Input: Task: corroborate the claim using the given text. Claim: Researchers are exploring genetic modifications in animals to better understand aging mechanisms. [SEP] Text: Because these dwarfs don't produce GH, they carry abnormally small IGF-1 concentrations, connecting a dearth of IGF-1 with slowed aging (see Bartke Viewpoint). Technical obstacles and ethical concerns preclude genetic manipulations to test the hypothesis in people. But nature might provide a viable avenue by which to explore the question: These dwarf rodents already have human counterparts. For instance, several human populations carry mutations in Prop1, the same gene that falters in Ames dwarf mice. These individuals could help researchers decipher how insulin and IGF-1 signaling affect aging in people. The prospects are tremendous, but bringing the idea to fruition will be laborious: Because these mutations are extremely rare--individuals with any given mutation typically number far less than 100--researchers can't get the volume of data necessary to make accurate assessments of longevity, says endocrinologist of School of Medicine in Atlanta, Georgia. Still, the promise these groups provide is too great to ignore. "It's imperative to look at the evidence for and against effects on life span in these humans," says Parks. One group of humans with inherited pituitary flaws lives on the island of Krk, off the coast of Croatia. Records provide ages of death for four individuals in this group, who lived to 68, 77, 83, and 91 years. "It's clear that they were older than average," says Parks--but if these folks are typical, the Krk inhabitants aren't as hardy as their rodent cousins are. "These were not people who were living to 120. " Why humans might show life span changes that are different from those of similarly modified rodents is unknown. Detrimental effects of hormone deprivation, which stunts growth, might be more pronounced in an organism that lives nearly 100--instead of about 2--years, or they might be minimized in the sheltered environment in which lab animals exist (see "Get Wild"). Researchers need to gather statistics on the 20 other known, affected individuals, but even with those numbers, getting robust longevity data will be difficult, says Parks: "The bottom line is, we're not sure exactly what's going on in these people [in terms of longevity]. " Complicating matters further, many individuals with these pituitary defects now receive hormone therapy; the therapy helps patients mature more normally, but "it kills the experiment," says physiologist of of Medicine in Springfield. Pituitary paradox. [SEP] Justify:

Output: The text corroborates the claim by discussing the potential for using genetically altered animals, specifically Ames dwarf mice, and their human counterparts, to explore aging mechanisms. It connects the low levels of IGF-1 in these dwarf rodents with slowed aging and highlights the efforts to understand how similar genetic modifications in humans might affect aging. The assertion that researchers need to gather statistics on affected individuals indicates an exploration of genetic modifications in relation to aging.


Input: Task: contrast the claim using the given text. Claim: BCI technology can currently allow users to fully control all electronic devices by thought alone. [SEP] Text: 956), although in their approach the user is required to do specific tasks on an Android-based platform, whereas our user can freely use their preferred device to navigate through a web document. Our findings suggest that the best classification device is a partial decision tree trained using a combination of features gathered through the evaluation of button clicks and scroll traces from 174 voluntary users, detecting the user operating hand with an TPR value of 99. 92. However, we must point out that whenever it is required to get a quick classification based on analysis of very few user interactions (n = 1, n = 2. . . ), the algorithms based on boosting techniques (such as AdaStump or ) are the ones that perform better. To the best of our knowledge, this approach is the first to explore and propose a solution for operating hand detection in mobile web applications using only data gathered from the touchscreen when the user spontaneous carries out web browsing tasks. Although the tasks studied are focused on click and scroll up/down, the relatively high level of classification accuracy obtained (99. 6%), ruled us out to explore the effect of other, no so common web browsing tasks, such as for example scroll left/right or zoom in/out. Unlike other proposals covered in this document, the proposed solution is based on implicit determination of the user’s handedness based on stealth observation of natural interaction tasks. It does not require users to perform uncommon tasks in order to determine their handedness. It neither requires to install platform dependant software on the target mobile device, neither the use of sensors, avoiding calibration an extra battery consumption. E-commerce web application developers can make use of these findings to detect the handedness of anonymous users visiting their web sites after observing their natural (spontaneous) interactions for a few time in stealth mode. The proposed algorithm is able to detect the user’s handedness with moderate-high level of accuracy, thus enriching the user model required by their applications through the user interface personalization process. Although discussion about how this personalization process may be implemented is beyond the scope of this paper, E-commerce applications may improve their user experience providing custom interfaces for left and right-handed users. Hence, the personalization process may provide accessibility-based solutions to the specific user interaction requirements of each kind of user. The data gathering agents developed in this study can be deployed in the target web applications to feed inference algorithms running on the server-side. [SEP] Justify:

Output: The text contrasts the claim by discussing a method of detecting user handedness based on interactions with mobile web applications and emphasizes that the user must perform specific tasks rather than controlling devices fully by thought alone. The focus on user interactions through button clicks and scroll traces indicates that current technology does not allow for complete thought-based control, thus undermining the assertion made in the claim.

Input: Task: corroborate the claim using the given text. Claim: Researchers are exploring genetic modifications in animals to better understand aging mechanisms. [SEP] Text: A family from the includes individuals with inherited pituitary deficiencies generated by a defect in Prop1. An affected 18-year-old girl (bottom row, right) appears unusually youthful compared with her unaffected 22-year-old sister (bottom row, left), but 40- and 38-year-old siblings (second row from the top, left and center) have already developed wrinkled skin and appear aged compared with their 35-year-old unaffected brother (second row, far right). The parents are in the top row, and three pituitary-deficient family members are in the third row (aged 33, 29, and 27, left to right). [Credit: A. L. Rosenbloom et al. , J. Clin. Endo. Metab. 84, 50-57 (1999)]Despite a paucity of longevity data, these populations are hinting at how altering hormone concentrations with the goal of extending life might impact health. Investigations of other humans with malfunctioning pituitaries suggest that even if such changes confer long life, they come with a downside. For instance, members of a family in the with mutations in the Prop1 gene are shorter than average and, even in their 20s, appear adolescent and don't show signs of puberty--so even if such individuals lived long, they'd be saddled with unusually small stature and fertility problems. They nevertheless exhibit characteristics of aging, such as wrinkled skin. Other individuals acquire age-related diseases unusually early. Members of the in North America--who also carry a Prop1 mutation--develop osteoporosis while still young, for example. In a Brazilian population with a genetic variation analogous to that carried by another long-lived dwarf rodent, the Little mouse, several people are in their 60s and 70s, establishing that they have at least normal longevity. However, many of them have increased blood pressure, cholesterol concentrations, and fat deposits. In addition, people in an Ecuadorian clan with Laron syndrome--caused by mutations in the gene that encodes the GH receptor protein--have relatively normal mortality. However, like the Brazilian population, they display risk factors for cardiovascular disease. Why these people have apparently normal life spans isn't clear. [SEP] Justify:

Output: The text corroborates the claim by discussing how specific genetic modifications, particularly related to the Prop1 gene mutations, influence aging and longevity in humans. It mentions how various populations with inherited genetic conditions related to hormonal functions are revealing insights that could contribute to understanding aging mechanisms, thereby aligning with the claim about the research focus on genetic modifications in animals.

In contrast, sham group subjects showed no increased performance. In addition to BCI performance, pre-stimulus alpha band power and the phase locking values (PLVs) averaged over sensory motor areas showed significant increases in low performers following stimulation in the vibrotactile stimulation and tDCS groups, while sham stimulation group subjects and high performers showed no significant stimulation effects across all groups. Our findings suggest that stimulation effects may differ depending upon BCI efficiency, and inefficient BCI users have greater plasticity than efficient BCI users. BackgroundBrain-computer interface (BCI) constitutes an interface between a computer and the human brain that allows people to control a computer using their brain activity without any body movements [1, 2]. BCI can be categorized according to its control features, in which motor imagery BCI is an active BCI that uses the brain signals generated when people imagine body movement, such as moving both hands, feet, and tongue [3, 4]. Motor imagery BCI applications have helped people by providing a game controlled by brain signals [5, 6] that improves rehabilitation training [7, 8]. Compared with other BCI control features, motor imagery is intuitive, so its BCI is natural to users, and it offers a greater sense of control than other BCI types because motor imagery BCI is active. However, challenging issues remain in BCI, including motor imagery BCI and other BCI systems. BCI researchers have reported that a significant proportion of subjects (approximately 15–30%), who are referred to as ‘BCI-illiterate’, failed to achieve controllable BCI performance [9,10,11,12].

It states that while BCI allows people to control computers using their brain activity, a significant portion of users (15–30%), referred to as 'BCI-illiterate', struggle to achieve controllable performance. This implies that not all users can fully control electronic devices by thought alone, challenging the claim's assertion of full control for all users.

Input: Task: corroborate the claim using the given text. Claim: Researchers are exploring genetic modifications in animals to better understand aging mechanisms. [SEP] Text: Such findings at first might disappoint those interested in manipulating hormone signaling to improve health--but these apparent contradictions resemble those seen in the long-lived rodents, bolstering the notion that the animals will yield insights into human physiology. Dwarf rodents also show signs of rapid aging, says geneticist of the in Bar Harbor, Maine. Despite having long lives ahead of them, young animals have abnormally low blood cell counts and their wounds heal slowly. On the other hand, the mice experience a slower than normal decline in brain function, says Bartke. "Characteristics of accelerated aging and delayed aging are [both] expressed in these dwarf mice," says Flurkey, "as if one aging clock is set ahead, and another is set back. "Despite the difficulties in distilling sound numbers from human populations, Parks thinks that these groups harbor important information. He wants to identify physiological parameters that provide an indicator of aging and measure them in these populations. Such studies could provide a more practical method of gauging longevity than life-span records. They could also reveal how quickly different tissues deteriorate, despite normal life span. He'd like to use "a battery of tests to give an inference of how far along these people are in the aging process. " No such study is in the works as of yet, and no one has uncovered a reliable biomarker for aging, but Parks says, "I need a really good aging associate: someone who knows all of the ins and outs of human aging and the limitations of the assays.

[Credit: Bernard Corenblum, University of Calgary]Data from humans with other problems might help bolster the endeavor.

Output: The text corroborates the claim by discussing research on dwarf rodents that exhibit both accelerated and delayed aging characteristics, suggesting that studying these animals can yield insights into aging mechanisms.

Input: Task: contrast the claim using the given text. Claim: BCI technology can currently allow users to fully control all electronic devices by thought alone. [SEP] Text: Those subjects were unable to generate the distinct brain activity pattern during a BCI task, so a machine learning-based classifier failed to extract stable features even though the subjects performed the BCI task. Although BCI researchers have proposed many applications and feature extraction algorithms, BCI illiteracy remains a significant challenge. To overcome BCI illiteracy so that everyone can achieve controllable BCI performance, researchers have approached the issue from multiple perspectives. One approach is to develop new feature extraction algorithms to identify hidden and robust features to improve BCI performance in the hope that they can extract control features from BCI-illiterate as well as good performers [13,14,15,16]. For example, Riemannian approaches calculate the Riemannian distance between the template covariance matrices and a single trial covariance matrix to determine the minimum distance class, which achieved improved performance [16], while deep learning techniques have achieved dramatically improved performance in subject-specific and cross-subject BCI models through multiple hidden layers [13, 14]. However, although those proposed advanced feature extraction algorithms improved BCI performance, it is unclear whether deep learning methods can improve everyone’s BCI performance. For example, Lee et al. [13] proposed subject-independent BCI using deep convolutional neural networks (CNNs), and tested it with 54 subjects. The subjects achieved better BCI performance compared to existing classification methods with respect to subject-specific and subject-independent BCI performance evaluation. However, the deep learning technique did not solve the BCI illiteracy issues fully, as low BCI performers still remained and achieved less than 50% accuracy (near chance level) in binary class motor imagery. Moreover, in Xu et al. ’s [17] investigation with eight different EEG datasets, the mean BCI performance was lower in the datasets with many subjects than in those with fewer subjects. It can be inferred that datasets with many subjects may contain more who are BCI-illiterate, and whose performance did not improve, while high BCI performers who had achieved controllable performance already with existing algorithms improved their performance further. Another approach extends beyond feature extraction algorithms that use the brain’s plasticity to modulate the brain activity related to specific BCI tasks that use external stimuli. This approach focuses more on the subject. [SEP] Justify:

Output: The text contrasts the claim by discussing the limitations of BCI technology, emphasizing the challenges of BCI illiteracy. It mentions that despite advancements in algorithms and techniques, many subjects still struggle to achieve controllable BCI performance, with low performers reaching less than 50% accuracy in tasks. This indicates that full control of electronic devices by thought alone is not currently achievable for all users, thereby challenging the assertion made in the claim.

Input: Task: corroborate the claim using the given text. Claim: Researchers are exploring genetic modifications in animals to better understand aging mechanisms. [SEP] Text: Parks says that if researchers engineer a mouse model of this so-called acquired hypopituitarism--triggered in some way other than cancer--it could help reveal whether leaving pituitary function intact during early life but negating it later could allow animals to develop normally yet live extra-long. Perhaps the animals would also provide insight into whether extended life span is separable from small body size, an ongoing controversy (see below). Mousing for LongevityResearchers will continue to strive for the ultimate prize: discerning how insulin-related signaling influences human life span. But scientists won't be able to uncover all the details they want from humans, so future work on rodents--dwarf and otherwise--will continue to contribute. Previous studies on the Ames and Snell animals suggested a connection between decreased IGF-1 amounts and longevity, but the mice also harbor reduced amounts of thyroid-stimulating hormone and prolactin, creating uncertainty about which alteration is responsible for life-span extension. Other dwarf mice implicate IGF-1 more directly, because they carry mutations that dampen only GH signaling. But GH can exert its influence on cells and tissues by routes other than those that involve IGF-1, so researchers have begun tweaking the IGF-1 system itself, rather than manipulating it through GH. For instance, scientists have removed the mouse gene that encodes the IGF-1 receptor (IGF-1R), a cell surface protein that gloms onto IGF-1. Animals that lack IGF-1R die soon after birth, but mice with a half-dose of IGF-1R survive--and live about 25% longer than normal mice do, according to work published in January 2003 in Nature (see "One for All"). To pinpoint how the hormone signals brake aging, future studies should tweak the pathway in more subtle ways, says neuroendocrinologist of of Medicine in Winston-Salem, North Carolina. For instance, previous work revealed that curtailing insulin-related signaling in worms during adulthood, but not during early life development, extends life span (see Sonntag and Ramsey Perspective). To find out whether the same holds true in mammals, "what we need are animal models where we can precisely control IGF-1 activity in adults or during development," he says. Bartke agrees: "We need to be more selective. [SEP] Justify:

Output: The text corroborates the claim by discussing how researchers are engineering mouse models to explore aging mechanisms, specifically through genetic modifications affecting IGF-1 signaling and pituitary function. It highlights the relevance of using animal models, particularly rodent studies, to uncover insights related to longevity and aging, indicating ongoing efforts in the research community to understand these complex processes.


Input: Task: contrast the claim using the given text. Claim: BCI technology can currently allow users to fully control all electronic devices by thought alone. [SEP] Text: Specifically, to target the brain activity related to motor imagery, two stimulation methods have been applied most frequently: vibrotactile and electrical brain stimulation. In the vibrotactile stimulation, it is known that somatosensory stimulation modulates corticospinal excitability and the stimulation can increase motor evoked potentials (MEPs) [18] and electroencephalographic sensorimotor rhythms [19]. Previous studies have investigated vibrotactile stimulation’s effects during motor imagery or execution and found that it improved motor imagery BCI performance by enhancing the contralateral event-related desynchronization (ERD) over the electrode channels around the motor cortex [20,21,22,23]. For example, Ahn et al. designed a hybrid BCI paradigm combined with tactile selective attention by giving attention to vibrotactile stimulation on the left or right index fingertips during motor imagery [20]. Further, Yao et al. utilized vibrotactile stimulation for delivering tactile sensation to assist somatosensory attentional orientation (SAO) task training. They found that real tactile sensation-based training significantly improved SAO performance after the assisted training blocks [24]. Motivated by Yao’s study, Zhong et al. applied tactile sensation for assisting motor imagery BCI training by delivering sustained vibrotactile stimulation during motor imagery training blocks and found significant training effects on BCI performance compared to non-assisted motor imagery training [25]. In addition, Shu et al. applied tactile stimulation to the unilateral wrist and observed improved BCI performance with enhanced contralateral cortical activation [22]. Similarly, it was found that tactile stimulation along with motor movement (wrist extensions of paretic hand) achieved enhanced motor-related cortical activation in the alpha to beta bands and improved decoding accuracy in stroke patients compared to non-tactile stimulation conditions [23]. Moreover, recent studies have observed that frequency- or phase-specific stimulation in vibrotactile stimulation or transcranial magnetic stimulation (TMS) may produce stronger stimulation effects compared to continuous stimulation [21, 26]. In particular, Zhang et al. compared the stimulation effects of continuous vibrotactile stimulation and closed-loop stimulation activated during the rising/falling phase of alpha waves, and found that the alpha falling phase stimulation outperformed continuous and rising phase stimulation in motor imagery classification accuracy and cortical activation around the motor cortex [21].

Output: The text contrasts the claim by discussing various methods of brain-computer interface (BCI) training that enhance motor imagery performance but does not suggest that users can fully control all electronic devices by thought alone. It specifically focuses on stimulation methods and their effects on motor imagery BCI performance, which implies limitations in current BCI technology rather than full control over electronic devices.

Input: Task: corroborate the claim using the given text. Claim: Researchers are exploring genetic modifications in animals to better understand aging mechanisms. [SEP] Text: We need to turn [IGF-1] off during different stages of life or turn it down or eliminate it in different types of cells. "Researchers are already beginning to conduct such studies. For instance, work published last year in by physiologist of the University of Michigan, Ann Arbor, and colleagues suggests that in mice, reduced IGF-1 concentrations early in life--rather than late, as in worms--is a key to longevity (see "the Earth"). That finding doesn't mesh with the way hormone therapy is administered. "The [U. S. Food and Drug Administration] recently made it possible to administer IGF-1 and GH deliberately to children who have no medical complaint other than they are short," says Miller. "That's remarkably shortsighted. All the evidence [supporting the notion that reducing IGF-1 extends life span] suggests that [this treatment] may be robbing children of life. "Insulin InsightsOther studies hint that combinations of signals might dial longevity up and down in mammals. In these creatures, the single worm and fly insulin-like pathway splits in two; insulin sparks one signal, and IGF-1 ignites the other. Insulin regulates metabolism, controlling glucose uptake from the blood into cells, whereas IGF-1 spurs cell growth and prods animals to develop into adults. Each pathway operates in many different tissues, and some tissues carry both systems. Moreover, both pathways harness many of the same components, and insulin and IGF-1 can each, when presenting high concentrations, activate the other hormone's receptor. Division of labor. IGF-1 and insulin utilize similar machinery to control separate cellular events. Insulin regulates primarily glucose uptake and storage, whereas IGF-1 spurs cellular reproduction and growth. How each of the pathways contributes to aging in mammals remains unclear, but rare human mutations and engineered rodents might help clarify the issue. [Source: V. D. Longo and C. Finch, Science 299, 1342-1346 (2003), Illustration: Julie White]Recent studies suggest that stifling insulin signaling delays aging. In work published last February in Science, diabetes researcher C. of the Center in Boston and colleagues engineered mice so that they don't make the insulin-receptor protein in their fat cells; the insulin receptor normally prods cells to store sugar as fat upon binding insulin.

Output: The text corroborates the claim by discussing research efforts that involve genetic modifications in animals, specifically mentioning engineered rodents and studies on insulin and IGF-1 pathways as a means to clarify aging mechanisms. The mention of reducing IGF-1 concentrations and how it relates to longevity in mice supports the idea that researchers are examining genetic modifications to gain insights into aging.

For example, Baxter et al. investigated the stimulation effects of high-definition tDCS (HD-tDCS) by placing anode and cathode electrodes between the CP3/P3 electrode channels, and observed that anodal stimulation decreased the mean time to achieve right-hand imagery successfully and increased alpha and beta band power at the C3/CP3 channels after the stimulation session [27]. However, previous tDCS studies have reported mixed effects with respect to the ERD after the tDCS session. In particular, some previous studies found an increase in ERD in the hemisphere stimulated during motor imagery tasks [29,30,31], while one found a decrease in ERD following the tDCS session [32]. Still another study found that tDCS did not affect frequencies above 9 Hz [33]. Rather than developing new feature extraction algorithms, external stimulation sources may have greater potential to solve the BCI illiteracy problem, as the stimulation methods affect brain activity. In contrast, feature extraction algorithms may fail to identify the robust features if they do not exist in the brain signals recorded from BCI-illiterate individuals. However, some limitations in the stimulation-based approaches need to be addressed. One consideration is the lack of a comparative study of vibrotactile stimulation and tDCS, the stimulation method used most frequently to modulate brain activity during motor imagery and improve motor imagery BCI performance. The difficulty in conducting a comparative study derives from the stimulation paradigm. In general, vibrotactile stimulation is delivered while subjects are performing a motor imagery task because the stimulation enhances the cortical activation that motor imagery induces [21] and thus, concurrent stimulation effects can be investigated. However, with tDCS, the stimulation effects are investigated following the stimulation session because recording EEG during the stimulation session is not applicable, and appropriate stimulation is necessary to modulate brain activity. Thus, to compare the stimulation effects, the stimulation paradigms should be equal. Here, we conducted a study to compare the stimulation effects of vibrotactile stimulation and tDCS with the same stimulation paradigm by assessing the effects of the vibrotactile stimulation following the stimulation session. Another consideration when investigating the stimulation effects is dividing the subjects according to BCI performance. [SEP] Justify:

Output: The text contrasts the claim by discussing the limitations and challenges associated with brain-computer interface (BCI) technology, particularly in the context of electrical stimulation methods like transcranial direct current stimulation (tDCS). It highlights that while stimulation can enhance BCI performance, there are mixed results and that issues such as BCI illiteracy and the need for stimulation paradigms to be equal complicate the current capabilities of BCIs. This suggests that full control of electronic devices by thought alone is not presently achievable.

Input: Task: corroborate the claim using the given text. Claim: Researchers are exploring genetic modifications in animals to better understand aging mechanisms. [SEP] Text: These lean animals carry only a small amount of fat and don't develop signs of diabetes, despite eating as much as or more than normal mice do. In addition, the animals live 20% longer than controls (see "Fasting"). The study implies that defects in insulin signaling stall aging, presumably in addition to the ones in the IGF-1 pathway that have been uncovered by the various dwarf mutation studies. Because of the similarities between the insulin and IGF-1 pathways, assessing which is most important in aging will be difficult, says molecular biologist of College of in Athens. But he's willing to speculate: "I think it's insulin," he says. Recent studies from his research team compared longevity of mice missing the GH receptor (Laron mice) and mice that produce a crippled GH variant that prevents normal signaling through the receptor. Mice without the GH receptor lived longer than normal, but mice with the altered GH molecule lived a normal life span. Although IGF-1 quantities are small in both animals, Kopchick says, insulin amounts are small only in the Laron mice. The result, he says, suggests that insulin is predominantly responsible for extra lifetime, although he doesn't exclude a role for IGF-1. Kopchick's research might also help resolve another controversy: whether reducing IGF-1 amounts extends life because it decreases body size. Much research points to a trend: Within a species--dogs or humans or mice--petite individuals tend to live longer. Researchers are currently trying to separate the body-shrinking and life-extending effects of reduced amounts of GH and IGF-1, says Bartke. For instance, Kopchick's study suggests that body size might not confer a longevity advantage. Both types of mice--those without the GH receptor and those with the GH blocker--were small, but only one was long-lived. If researchers can tease these qualities apart, they might eventually be able to extend life while preserving normal stature. Although lab results suggest that limiting IGF-1 and GH extends longevity, consumers shell out untold dollars on GH-boosting injections, supplements, and sprays. Thanks to crafty sales pitches based on shaky claims, some adults believe that a burst of hormone--rather than a dearth of it--will counteract aging's toll, keeping them wrinkle-free and virile. [SEP] Justify:

Output: The text corroborates the claim by discussing various studies on genetic modifications in mice that affect their longevity and potential aging mechanisms. Specifically, it highlights research on mice with altered GH receptor signaling and IGF-1 pathway comparisons, suggesting that these genetic factors may help in understanding how aging works. The focus on manipulating these genetic pathways to discern their influence on lifespan aligns directly with the claim regarding researchers exploring genetic modifications to better understand aging.


Input: Task: contrast the claim using the given text. Claim: BCI technology can currently allow users to fully control all electronic devices by thought alone. [SEP] Text: Previous studies have found that inefficient (low performers) and efficient BCI users (high performers) exhibited different neurophysiological characteristics. One study incorporated brain network features into ERD to improve low performers’ motor imagery BCI performance [34]. They found that the subjects benefited from brain network features (functional connectivity), and suggested that low performers may engage in motor imagery differently than high performers, and thus existing features, such as ERD, cannot capture the engagement, although the brain network showed the possibility. Similarly, another study divided the subjects recruited into two groups based upon BCI performance, compared their brain networks on multiple network scales [35], and found significantly higher phase synchronization values in the right hemisphere during high performers’ motor imagery. In addition to brain network measures, a difference between low and high BCI performers’ frequency band power has been reported during the rest or pre-stimulus period, showing that subjects with higher alpha band or sensory motor rhythm (SMR) power during those periods are more likely to achieve better BCI performance [36,37,38]. Based upon these previous findings, it can be expected that vibrotactile stimulation or tDCS affects low and high performers differently because the two show different characteristics and may engage in the same task in different ways. In addition to the neurophysiological perspective, they may differ from the behavioral perspective. High performers who achieve controllable BCI performance before the stimulation session have a sense of control already, and their brain activity is optimal and stable in the task. Therefore, external changes are less likely to affect them. On the other hand, low performers do not have this sense of control, and their brain activity is not yet optimal or stable. Therefore, low performers may have more potential to change. In this study, we compared vibrotactile stimulation and tDCS’s stimulation’s effects on brain activity related to motor imagery among inefficient BCI users. Through this study, we investigated which brain activity can be modulated by vibrotactile stimulation and tDCS and whether they can help improve low performers’ BCI performance. MethodsExperimental procedure and data acquisitionWe recruited a total of 44 healthy subjects for this study, and assigned them randomly to three groups—sham (control), vibrotactile stimulation, and tDCS. This experiment was conducted in a quiet space, and the subjects were seated in a comfortable chair approximately one meter from a 24-inch screen. [SEP] Justify:

Output: The text contrasts the claim by indicating that not all BCI users can fully control devices by thought alone. It discusses differences between low and high performers in BCI technology and how their brain activity varies, suggesting that while high performers may achieve controllable BCI performance, low performers do not have the same level of control. The text elaborates on the neurophysiological characteristics that differentiate these performers, highlighting that low performers lack a sense of control and optimal brain activity, which contradicts the notion that BCI technology allows full control universally.

Input: Task: contrast the claim using the given text. Claim: BCI technology can currently allow users to fully control all electronic devices by thought alone. [SEP] Text: Thereafter, the subjects performed the online phase, which consisted of two motor imagery blocks that showed visual feedback, for 1. 5 s by moving the circle to classified directions. For CSP-FLDA, an epoch was extracted from each trial at [1000–3500] ms to the stimulus onset, and band-pass filtered with cutoff frequencies of 8 and 30 Hz using the 4th -order Butterworth filter. However, we note that hyper-parameters for online classifiers were changed after the first ten subjects. Specifically, for the first ten subjects, CSP-FLDA was trained by 19 electrode channels and the first and last two CSP filters were selected. However, electrodes around the eyes and occipital areas often yielded notable noise with high variation attributable to non-brain activity, such as motion artifacts, eye movements, and bad contacts. As a result, for the remaining subjects, nine electrode channels around the central area, including the F3, Fz, F4, C3, Cz, C4, P3, Pz, and P4 channels, were used to train CSP, and the first and last CSP filters were selected to train FLDA. In this study, we calculated offline BCI performance to compare BCI performance with the same hyper-parameter over all subjects, as described in Sect. 2. 3. Stimulation session designIn this study, we compared the stimulation effects on brain activity modulation and relevant BCI performance. Depending upon the stimulation group, each subject performed a stimulation session in the middle of two motor imagery sessions. The stimulation groups consisted of the vibrotactile stimulation group, tDCS group, and sham stimulation group. Fig. 2 illustrates the stimulation session for each group. All stimulation group subjects performed four blocks of offline motor imagery task while receiving stimulation. Fig. 2Vibrotactile stimulation, tDCS, and sham stimulation.

Input: Task: corroborate the claim using the given text. Claim: One focus of anti-aging research is studying genetic markers associated with longevity in certain populations. [SEP] Text: Figures AbstractIn humans (UCPs) are a group of five mitochondrial inner membrane transporters with variable tissue expression, which seem to function as regulators of energy homeostasis and antioxidants. In particular, these proteins uncouple respiration from ATP production, allowing stored energy to be released as heat. Data from experimental models have previously suggested that UCPs may play an important role on aging rate and lifespan. We analyzed the genetic variability of human UCPs in cohorts of subjects ranging between 64 and 105 years of age (for a total of 598 subjects), to determine whether specific UCP variability affects human longevity. Indeed, we found that the genetic variability of UCP2, UCP3 and UCP4 do affect the individual's chances of surviving up to a very old age. This confirms the importance of energy storage, energy use and modulation of ROS production in the aging process. In addition, given the different localization of these UCPs (UCP2 is expressed in various tissues including brain, hearth and adipose tissue, while UCP3 is expressed in muscles and Tissue and UCP4 is expressed in neuronal cells), our results may suggest that the uncoupling process plays an important role in modulating aging especially in muscular and nervous tissues, which are indeed very responsive to metabolic alterations and are very important in estimating health status and survival in the elderly.

Input: Task: contrast the claim using the given text. Claim: BCI technology can currently allow users to fully control all electronic devices by thought alone. [SEP] Text: 34G vibration amplitude. board was triggered through serial communication with scripts for closed loop vibrotactile stimulation. Recent studies have shown that EEG-guided stimulation can enhance the stimulation effects in vibrotactile stimulation and transcranial magnetic stimulation (TMS) by targeting motor cortex excitability states [21, 26]. Researchers have observed that stimulation triggered by the EEG alpha falling phase outperformed continuous stimulation with respect to the motor evoked potential (MEP) [26] amplitude and motor imagery BCI performance [21]. In this respect, our study applied vibrotactile stimulation according to the EEG alpha (8 ~ 13 Hz) phase at the electrode channels on the left (C3) and right motor cortex (C4) as in [21]. Specifically, during the vibrotactile stimulation session, the subjects were instructed to place their left and right index fingertips on each vibration motor. For each trial, 500ms-long epoch was extracted from the contralateral EEG channel every 50ms (with overlapping 450ms) to calculate the alpha phase. The epoch extracted was band-pass filtered in the [8,9,10,11,12,13] Hz frequency range using a 10th -order elliptical infinite impulse response (IIR) filter, and the phase was calculated using the Transform (FFT)-based phase tracking algorithm, as proposed and adopted previously [21, 41]; among the FFT amplitudes, the dominant alpha frequency component between 8 and 13 Hz and the corresponding phase were used to obtain a simple sine function to predict the upcoming phase. When the phase predicted was falling, the vibration was delivered through the left or right vibration motor for 100ms according to the motor imagery class, and the inter-stimulation interval was set to 100ms. Thus, the C4 channel alpha phase was extracted for the left-hand motor imagery trials, and the left vibration motor was activated when the phase predicted was falling and the converse. With respect to the technical details, during the vibrotactile stimulation session, EEG data and event markers that represented left- or right-hand motor imagery were streamed into scripts. To minimize delay and synchronize the EEG data and event markers, a trigger hub (Wearable Sensing, USA) was used to integrate the EEG data and event markers into the EEG device, and merged data were acquired over the wire. [SEP] Justify:

Output: The text contrasts the claim by detailing a specific scientific study on vibrotactile stimulation and EEG-guided stimulation, which indicates that while BCI technology can enhance certain actions, it does not demonstrate that users can fully control all electronic devices solely by thought. Instead, the text describes complex methods involving motor imagery and EEG data integration, implying limitations rather than the claim of full control.

Input: Task: corroborate the claim using the given text. Claim: One focus of anti-aging research is studying genetic markers associated with longevity in certain populations. [SEP] Text: Consistently, mice subjected to CR show an increased expression of Ucp2 and Ucp3 [37], [38]. In humans the correlation between mitochondrial uncoupling and aging emerges from association studies which support a role for UCPs in many age-related phenotypic traits involving alterations in cellular energy homeostasis such as obesity, diabetes and lipid-related diseases [39]–[41]. We recently performed a population-based study in a human cohort of elderly subjects which demonstrated that UCP3 variability has an impact on hand grip strength, one of the most important hallmarks of human aging [42] and more recently we also found that two variants (A-3826G and C-3740A) in the upstream enhancer region of human UCP1 gene affect the expression of the gene and are correlated with human longevity [43]. Given the tissue-specific expression of UCP genes, it seems likely that they may affect the senescence of different tissues with important effects on the overall aging process and consequently on lifespan. Thus, the goal of the present study was to assess both the primary effects of single loci and gene-gene interactions to test the hypothesis that other UCP genes may contribute to survival at very old age either independently and/or through complex interactions. statement Samples were collected within the framework of several recruitment campaigns carried out for monitoring the quality of aging in Calabria from 2002. The recruitment campaigns and subsequent analyses received the approval of the Ethical committee of the University of Calabria. All subjects provided written informed consent for studies on aging carried out by our research group. White blood cells (WBC) from blood buffy coats were used as a source of DNA. A total of 598 subjects (293 men and 305 women, age range 64–105 years; mean ages 82. 74 (±11. 66) and 85. 23 (±10. 84) years, respectively) participated in this study. All subjects were born in Calabria (southern Italy) and their ancestry in the region was ascertained up to the grandparents' generation. Younger subjects were contacted through family physicians. Subjects older than 90 years were identified through the population registers and then were contacted by specialized personnel and invited to join the study. Each subject underwent a medical visit carried out by a geriatrician who also conducted an interview including the administration of a structured questionnaire, validated at European level.

Input: Task: contrast the claim using the given text. Claim: BCI technology can currently allow users to fully control all electronic devices by thought alone. [SEP] Text: The stimulation session continued until the subjects performed four blocks of the offline motor imagery task, although we did not record EEG during the tDCS session because of electrical interference. The subjects were informed that they could stop the stimulation at any time if they felt severe pain. In addition, the sham stimulation group (control group) subjects performed the same task as the tDCS group subjects, but they received sham, rather than actual stimulation. For the sham group, the stimulation turned off after the ramping period, and the subjects did not know whether they belonged to the tDCS or sham stimulation group. After the stimulation session, the subjects washed their hair and were re-fitted with the EEG cap. Then, they performed the same motor imagery task that they did before the stimulation session. BCI performance evaluationThis study used offline BCI performance because online BCI classification parameters were not the same for all subjects. To evaluate the subjects’ BCI performance, the EEG data were band-pass filtered with 8–30 Hz using the 4th -order Butterworth filter, and any 60 Hz line noise that remained was filtered out with the band-stop filter from 58 to 62 Hz. Epochs were extracted from 500 to 3500 ms to the stimulus onset, which is the time window obtained heuristically. Except for the electrodes near the eyes, those with an amplitude greater than ± 100µV were removed, and subjects who had more than 30% of bad trials among all trials were eliminated from the analysis. Finally, we chose a region of interest (ROI), the nine electrode channels (F3, Fz, F4, C3, Cz, C4, P3, Pz, and P4), for motor imagery BCI classification using visual inspection. To evaluate BCI performance, the first two motor imagery blocks (offline phase) were used for training, and the remaining two blocks were used for testing. minimum distance metric (MDM) [16] was used to extract features and evaluate BCI performance. In this study, the subjects performed the motor imagery task before and after the stimulation session to evaluate stimulation effects on brain activity during motor imagery. Moreover, we divided each stimulation group into low- and high-performing groups according to their pre-stimulation BCI performance, as previous studies have observed that the two showed different neurophysiological characteristics [9, 36]. [SEP] Justify:

Output: The text contrasts the claim by detailing a study on offline BCI performance evaluation, which indicates that while brain-computer interface (BCI) technology is being researched and developed, it does not provide the capability for users to fully control electronic devices solely by thought. The mention of the motor imagery tasks and the complexity of evaluating BCI performance suggests limitations in current technology rather than the full control of devices as claimed.

Input: Task: corroborate the claim using the given text. Claim: One focus of anti-aging research is studying genetic markers associated with longevity in certain populations. [SEP] Text: One of these is the MAX3 test which assumes the maximum of three different Cochran-Armitage trend tests (CATTs) evaluated with respect to three different genetic models of inheritance: dominant, additive or recessive [46], [47]. The main drawback of such tests is represented by the fact that they could be seriously affected by confounding factors [48]. In this context, So and Sham recently proposed a robust association test allowing for quantitative or binary traits as well as covariates [49]. This test was based on the score test and has been implemented in the R package RobustSNP. In the present study the robust association test proposed by So and Sham was applied to estimate the association between the variability in the UCP genes and the probability of reaching advanced ages. In each test we included sex and Index (BMI) as covariates. Haplotypic analysis Pairwise measures of linkage disequilibrium (LD) between the analyzed loci were calculated with the Haploview 4. 2 [50]. The amount of LD was quantified by Lewontin's coefficient (D'). In order to model the effect of the UCP haplotypes on the probability to attain longevity we used the haplo. stats package of R. It implements a haplotype-based association analysis within the generalized linear model (GLM) framework that allows for ambiguous haplotypes. The haplo. score function of this package has been used to obtain the GLM-based score statistics for testing global and individual haplotype effects on the probability to attain longevity [51]. Permutation-based p-values were used to evaluate the significance of the scores obtained (10000 permutations). In this model the effect of the different haplotypes was assessed assuming a dominant model after adjusting for sex and BMI. Interaction analysis In order to explore the interaction effects between the analyzed polymorphisms on the probability to be part of the very old age group, the Model-(MB-MDR) method was applied [52]. In this model only all possible second order interactions, after adjusting for main effects sex and BMI, were analyzed. All statistical analyses were performed using genetics, RobustSNP, mbmdr and haplo. stats packages of R 2. 10. 1. ResultsTable 2 reports the socio-demographic characteristics of the sample analyzed according to age group. The observed genotype frequencies (Table S1) were in agreement with those expected at HWE (p>0. [SEP] Justify:

Output: The text corroborates the claim as it discusses a robust association test that estimates the association between variability in UCP genes and the probability of reaching advanced ages. This research aligns with the focus on studying genetic markers associated with longevity, as indicated by the analysis of haplotypes and their effects on reaching old age.


Input: Task: contrast the claim using the given text. Claim: BCI technology can currently allow users to fully control all electronic devices by thought alone. [SEP] Text: Further, our previous study suggested that low and high BCI performers should be treated differently because low BCI performers’ features decreased the ability to generalize the cross-subject BCI model significantly, while subject selection may have increased cross-subject BCI performance [42]. In addition, we assumed that low BCI performers may have greater potential to change their brain activity through learning or external stimulation, for either better or worse, compared to high BCI performers because high BCI performers’ brain activity may be stable and optimal already. To divide the subjects into low and high BCI performance groups, a previous study used the median value of the BCI performance [35], as the median value can divide groups with the same size and allow analysis to be performed on sub-groups of the same size. However, the distribution and sample size affect the median value. Accordingly, if the BCI performance data collected are biased toward high or low performance, the divided groups do not represent true high or low performance groups. Instead, we used the statistical random probability introduced in [43] and used in our previous study [42] to divide low and high BCI performers, as it can produce a random threshold based upon the number of trials and the statistical significance. With 40 test trials and α = 0. 05, we obtained 60. 69% as a threshold to divide low and high BCI performers. As a result, we divided each stimulation group’s subjects into low and high BCI performers based upon their pre-stimulation performance and investigated the stimulation effects in the subgroups. Pre-stimulus band power for motor imageryThe pre-stimulus band power was calculated from the online phase of the motor imagery task before and after the stimulation session. For clarity, we note that the pre-stimulus band power refers to the band power calculated from the window preceding the motor imagery onset in every trial, and it is distinct from the stimulation session. Thus, pre-stimulus band powers were calculated during the motor imagery task before/after the stimulation. Maeder et al. investigated the relation between the pre-stimulus sensory motor rhythm (SMR) band power and motor imagery BCI performance and observed that higher pre-stimulus SMR trials yielded significantly better performance compared to lower trials [37]. [SEP] Justify:

Output: The text contrasts the claim by discussing the complexities of BCI performance and the differences between low and high BCI performers. It implies limitations in BCI technology, such as the influence of performer characteristics on the ability to generalize across subjects and the potential for performance bias. The mention of dividing subjects based on performance metrics suggests that full control of devices through thought alone is not currently achievable for all users, particularly those classified as low BCI performers.

Table 3 reports the results of the association test for the three different genetic models (dominant, additive and recessive) obtained in the analyzed sample using the RobustSNP algorithm. Table 3 clearly shows that the variability of the UCP polymorphism was significantly associated with the analyzed phenotype. In particular, using the minor allele for each SNP as reference and after adjusting for BMI and sex, the dominant model for the rs660339 (UCP2) and the rs1800849 (UCP3) resulted to be significantly associated with the longevity phenotype (p = 0. 001 in both cases), while the recessive model was the most likely for SNPs rs15763 (UCP3), rs9472817 (UCP4) and rs2235800 (UCP5) (p<0. 05). However, after adjusting for multiple testing, all the previous associations remained statistically significant, except those for rs2235800 of the UCP5 gene (p = 0. 058).

Results of the Robust SNP association test for the most likely genetic model (additive, recessive and dominant) obtained in the analyzed sample. the z-statistics of these models we observed that carriers of the T allele at rs660339 and at rs1800849 (dominant models) significantly influenced the probability to be part of the oldest group (positive scores). For the recessive models, homozygous subjects for the T allele at rs15763 variation also increased the probability to be part of the oldest group, while this probability was significantly decreased (negative score) for homozygous subjects with the T allele at rs9472817. By using the MB-MDR approach we did not find any significant interaction effect among the analyzed polymorphisms (data not shown). Subsequently, using the aforementioned GLM-based algorithm, we evaluated the effect of the UCP haplotypes on the probability to attain longevity. LD analysis showed that among the four SNPs in the UCP2-UCP3 gene region rs660339, rs659366 and rs15763 were in moderate LD (see Fig. [SEP] Justify:

Output: The text corroborates the claim by discussing specific genetic markers associated with longevity. It details findings related to the UCP polymorphism and how certain SNPs, particularly rs660339 and rs1800849, are significantly associated with the longevity phenotype, which aligns directly with the focus of anti-aging research on genetic markers in certain populations.


Input: Task: contrast the claim using the given text. Claim: BCI technology can currently allow users to fully control all electronic devices by thought alone. [SEP] Text: The global PLV was obtained by averaging all PLVs between the nine electrode channels, as illustrated by the bold linesFull size image The PLVs were compared in this study before and after the stimulation session using a paired Student’s t-test for subjects with low and high BCI performance in the sham, vibrotactile stimulation, and tDCS groups to assess the stimulation effects on the average strength of the connection around the central areas during motor imagery. ResultsAmong the 44 subjects who were assigned randomly to the three stimulation groups—sham, vibrotactile stimulation, and tDCS—bad subjects (> 30% bad trials), including one who failed to concentrate on the post-stimulation motor imagery task because of a significant delay in setup after the stimulation session, were removed from the analysis. As a result, 39 subjects remained: 12, 13, and 14 subjects in the sham, vibrotactile, and tDCS groups, respectively. Moreover, we divided each stimulation group into low and high BCI performance groups using statistical random probability. With respect to the low and high BCI performance groups, the subjects in each group who achieved a performance lower than 60. 69% were assigned to the low BCI performance group, and the remaining subjects were assigned to the high BCI performance group. As a result, sham group subjects were divided into 6 low performers and 6 high performers, vibrotactile stimulation group subjects were divided into 10 low performers and 3 high performers, while the tDCS group subjects were divided into 10 low performers and 4 high performers. Although we assigned the stimulation groups randomly, the vibrotactile stimulation and tDCS groups included more low performers than the sham stimulation group. Stimulation effects on BCI performanceMotor imagery BCI performances during pre-stimulation and post-stimulation are depicted in Table 1; Fig. 4. Low performers in the sham stimulation group achieved 53. 75% (43. 75 ~ 60%), and high performers achieved 71. 88% (63. 75 ~ 95%) before the pre-stimulation session. After the sham stimulation session, low performers achieved 53. 99% (43. 75 ~ 61. 25%), showing no significant change. However, the high performers’ BCI performance decreased to 62. 71% (47. 5 ~ 85%). On the other hand, the low performers in the actual stimulation groups, the vibrotactile stimulation and the tDCS groups, showed improved performance. [SEP] Justify:

Output: The text contrasts the claim by providing detailed information about a study on brain-computer interface (BCI) performance, indicating that subjects in the experiment were grouped by performance levels and showing figures for low and high BCI performances. It specifically mentions that after the stimulation sessions, there was no significant improvement for low performers and a decrease for high performers after sham stimulation. This suggests that the current technology does not enable full control of electronic devices by thought alone but rather reflects variability and limitations in BCI performance.

Input: Task: corroborate the claim using the given text. Claim: One focus of anti-aging research is studying genetic markers associated with longevity in certain populations. [SEP] Text: DiscussionSubstantial evidence suggests that the ability of UCPs to reduce ROS and regulate energy utilization underpins the ability of UCPs to promote lifespan in various experimental models [27], [28], [29], [30], [35]. In the present study we found that variants in UCP2, UCP3, and UCP4 significantly affect an individual's chances of becoming ultra-nonagenarians. The different localization of the proteins we found associated with longevity allows us to predict the areas where the uncoupling process may play an important role in survival at very old age. UCP2 and UCP3 genes cluster on chromosome 11q13 in a region linked to lower resting metabolic rate in humans [53], which is also syntenic to a region of mouse chromosome 7 linked to hyperinsulinemia and obesity [54]. Their chromosomal location and their association with fatty acid transport across mitochondrial inner membrane and β-oxidation, support the hypothesis that, in addition to functioning as regulators of oxidative stress, both UCP2 and UCP3 can modulate cellular energy metabolism [16], [55]. While mounting evidence has documented the importance of both UCP2 and UCP3 variability in the pathophysiology of different chronic metabolic diseases, such as diabetes and obesity [41], [56], relatively little is known of their implication in human aging and longevity. In this study we found that the Ala55Val (rs660339) of UCP2, and -55 C/T (rs1800849) and rs15763 of UCP3 were significantly associated with survival at very old age after Bonferroni correction. Ala55val SNP in exon 4 causes a conservative amino acid change that does not seem to cause a functional change in the protein. However, it has been reported that the Val/Val genotype causes a lower degree of uncoupling, an enhanced metabolic efficiency, and a lower fat oxidation than the Ala/Ala and Ala/Val genotypes [57]. In addition this genotype has been associated to higher exercise energy efficiency [58], higher risk in obesity, higher incidence of diabetes [59], [60], and a higher acute insulin response to glucose [61]. Moreover, individuals with the Val/Val genotype had greater weight loss and a higher BMI [62]. Nevertheless, other studies have produced conflicting results [63]–[66]. [SEP] Justify:

Output: The text corroborates the claim by discussing specific genetic variants (UCP2 and UCP3) that are significantly associated with prolonged survival into very old age. It highlights how studying these genetic markers may help in understanding longevity, providing evidence that aligns with the focus of anti-aging research on genetic markers linked to lifespan.
