Tensor glyph

In scientific visualization a tensor glyph is an object that can visualize all or most of the nine degrees of freedom, such as acceleration, twist or shear – of a ${\displaystyle 3\times 3}$ matrix. It is used for tensor field visualization, where a data-matrix is available at every point in the grid. "Glyphs, or icons, depict multiple data values by mapping them onto the shape, size, orientation, and surface appearance of a base geometric primitive."[1] Tensor glyphs are a particular case of multivariate data glyphs.

When creating a new protection group in DPM 2007 RTM you are presented with a list of computers on your network that have the DPM client installed.  The DPM server itself is in this list as it also runs the client for various reasons, including the ability to be backed up by another DPM server.

When you go to expand the local DPM server node you find a very small, or non-existent list of data that can be protected.  If you are running the DPM SQL database on the local machine, that will be the only thing available, otherwise there is absolutely nothing.

[caption id="attachment_19" align="alignnone" width="591" caption="Local Protection Disabled"][/caption]

DPM 2007 SP1 now includes the ability to protect resources local to the DPM server itself. This feature is being described by Microsoft as a way to build an all-in-one branch office server.  You can now run DPM on the same server that is providing file sharing, database, and other services to your branch office and use it to protect that data. Once the branch-office DPM server is protecting its local data you can then use the DPM server at your main office to protect it, “Instant Disaster Recovery” says Microsoft.

## Configuration

This new feature is implicitly disabled and must be enabled using a powershell cmdlet. Enable this feature using the Set-DPMGlobalProperty cmdlet, launch a DPM Management Shell session and enter the following incantation:

Set-DPMGlobalProperty –AllowLocalDataProtection $true my-dpm-server If for some reason you need/want to disable this feature, just change$true to \$false.

Now when creating a new protection group you should see the Shares and Volumes nodes available under your DPM server where only DPMDB existed before.

[caption id="attachment_20" align="alignnone" width="592" caption="Local Protection Enabled"][/caption]

## Using

This feature came not a moment too soon.  We don't currently need it for a branch-office configuration but I do need this feature rather badly for doing disk image backups of our VMWare infrastructure using DPM.  VMWare's Consolidated Backup mounts remote disk images as local directories, and without this feature I would have to use a third machine to act as the VCB proxy. Having a proxy would require not only another machine, but another node in the data flow between my VMs and tape.

I’ll explain indepth how I am using DPM to backup VMWare Infrastructur using VMWare Consolidated Backup in a future post.

## Dependence relation among values of canonical heights

### Abstract

Let $d\geq 2$ and let $H$ denote the absolute multiplicative Weil height on $\bar{\mathbb{Q}}$. Let $f(z)\in \bar{\mathbb{Q}}[z]$ of degree $d$ and let $a\in\bar{\mathbb{Q}}$, the multiplicative and logarithmic canonical heights of $a$ with respect to $f$ are defined as

$$\hat{H}_f (a) =\lim H(f^n(a))^{1/d^n} \quad \text{and}\quad \hat{h}_f(a)=\log \hat{H}_f(a).$$

Let $n$ be a positive integer. For $1\leq i\leq n$, let $f_i\in\bar{\mathbb{Q}}[z]$ of degree $d$ and let $a_i\in\bar{\mathbb{Q}}$. In this talk, we provide a complete characterization of when the $\hat{H}_{f_i}(a_i)$’s are multiplicatively dependent modulo constant meaning there exist integers $m_1,\ldots,m_n$ not all of which are $0$ and $a\in \bar{\mathbb{Q}}$ such that:

$$\hat{H}_{f_1}(a_1)^{m_1} \cdots \hat{H}_{f_n}(a_n)^{m_n}=a.$$

As an immediate consequence, we characterize all the pairs $(f,a)$ such that $\hat{H}_f(a)$ is an algebraic number and proves the existence of $(f,a)$ such that $\hat{h}_f(a)$ is an irrational number. The proof uses the Medvedev-Scanlon classification of preperiodic subvarieties under the dynamics of a split polynomial map and the construction of a certain auxiliary polynomial. This is joint work with Jason Bell.

# Zinc–copper couple

(Redirected from Zinc-copper couple)

Zinc–copper couple is an alloy of zinc and copper that is employed as a reagent in organic synthesis. The “couple” was popularized after the report by Simmons and Smith in 1959 of its application as an activated source of zinc required for formation of an organozinc reagent in the Simmons–Smith cyclopropanation of alkenes.[1] The couple has been widely applied as a reagent in other reactions requiring activated zinc metal. Zinc–copper couple does not refer to a rigorously defined chemical structure or alloy composition. The couple may contain varying proportions of copper and zinc; the zinc content is typically greater than 90%, although an alloy containing similar proportions of zinc and copper is used in some cases. The couple is frequently prepared as a darkly-colored powder and is slurried in an ethereal solvent prior to being used in slight excess relative to the substrate. Activation of zinc by copper is essential to the couple’s utility, but the origin of this effect is poorly documented. It is speculated that copper enhances reactivity of zinc at the surface of the alloy.[2]

## Synthesis

Zinc–copper couple has been prepared by numerous methods, which vary mainly with respect to the source of copper, but also by the ratio of copper to zinc, the physical state of the zinc (e.g. powder or granules), the use of protic acids and other additives, and temperature of the preparation. Most often the couple is generated and isolated prior to use, but routes have been described to storable forms of the alloy. Most methods involve reduction of an oxidized copper species with zinc, which is used in excess.

An early method for the synthesis of zinc–copper couple entailed treatment of a mixture of zinc dust and copper(II) oxide with hydrogen gas at 500 °C.[1] A more convenient and cheaper method proceeds by treatment of zinc powder with hydrochloric acid and copper(II) sulfate.[3] Treatment of zinc powder with copper(II) acetate monohydrate in hot acetic acid is reportedly highly reproducible.[4] The couple may also be generated in situ by reaction of one equivalent of zinc dust with one equivalent of copper(I) chloride (or copper powder) in refluxing ether.[5]

The choice of method is dictated primarily by the application. The development of newer methods was motivated by the need for zinc–copper couple with reproducible behavior.

## Application

Zinc–copper couple has found widespread use in organic synthesis, especially in the Simmons–Smith cyclopropanation of alkenes. In this process, the couple (typically a slurry in an ethereal solvent) reacts with methylene iodide to generate iodomethylzinc iodide, which is the intermediate responsible for cyclopropanation.

${\displaystyle {\ce {{Zn_{\mathit {n}}(Cu)}+CH2I2->{IZnCH2I}+Zn_{{\mathit {n}}-1}(Cu)}}}$

The couple has also been employed to generate alkyl zinc reagents for conjugate addition, as a dehalogenating reagent, as a promoter of reductive coupling of carbonyl compounds, and to reduce electron-deficient alkenes and alkynes. Sonication has been employed to enhance the rate of the zinc–copper couple-mediated cycloaddition of α,α’-dibromo ketones to 1,3-dienes.[6]

A hallmark of imprinted genes in mammals is the occurrence of parent-of-origin-dependent asymmetry of DNA cytosine methylation (5m C) of alleles at CpG islands (CGIs) in their promoter regions. This 5m CpG asymmetry between the parental alleles creates allele-specific imprinted differentially methylated regions (iDMRs). iDMRs are often coupled to the transcriptional repression of the methylated allele and the activation of the unmethylated allele in a tissue-specific, developmental-stage-specific and/or isoform-specific fashion...

The job of the diagnostic radiologist is two-fold: identifying and interpreting the information available from diagnostic imaging studies and communicating that interpretation meaningfully to the referring clinician. However skilled our interpretive abilities, our patients are not well served if we fail to convey our conclusions effectively. Despite the central importance of communication skills to the work of radiologists, trainees rarely receive significant formal training in reporting skills, and much of the training given simply reflects the trainer's personal preferences...

Prediction of the magnetic moment of binary body centered cubic (BCC) is explored in terms of first principle calculations and data science. A dataset of 1,541 binary BCC materials constructed by first principle calculations is implemented for data mining. Descriptors for determining the magnetic moment are explored using machine learning, where classification and regression models are both implemented. Data mining reveals that two descriptors are responsible for classifying whether the materials have zero or nonzero magnetic moments and can also classify which groups of magnetic moments they belong to ($\mu_{B}$ $<$ 1, 1 $\leq$ $\mu_{B}$ $<$2,or 2 $\leq$ $\mu_{B}$ $<$ 3) where the average scores produced in cross validation indicate 80$\%$ and 91$\%$ accuracy, respectively...

New drug development is both resource and time intensive, where later clinical stages result in significant costs. We analyze recent late-stage failures to identify drugs where failures result from inadequate scientific advances as well as drugs where we believe pitfalls could have been avoided. These can be broadly classified into two categories: 1) where science is mature and the failures can be avoided through rigorous and prospectively determined decision-making criteria, scientific curiosity, and discipline to follow up on emerging findings; and 2) where problems encountered in Phase 3 failures cannot be explained at this time, as the science is not sufficiently advanced and companies/investigators need to recognize the possibility of deficiency of our knowledge...

Tissue Phenomics is the discipline of mining tissue images to identify patterns that are related to clinical outcome providing potential prognostic and predictive value. This involves the discovery process from assay development, image analysis, and data mining to the final interpretation and validation of the findings. Importantly, this process is not linear but allows backward steps and optimization loops over multiple sub-processes. We provide a detailed description of the Tissue Phenomics methodology while exemplifying each step on the application of prostate cancer recurrence prediction...

BACKGROUND: Dengue fever is a re-emerging viral disease commonly occurring in tropical and subtropical areas. The clinical features and abnormal laboratory test results of dengue infection are similar to those of other febrile illnesses; hence, its accurate and timely diagnosis for providing appropriate treatment is difficult. Delayed diagnosis may be associated with inappropriate treatment and higher risk of death. Early and correct diagnosis can help improve case management and optimise the use of resources such as hospital staff, beds, and intensive care equipment...

Social media are becoming an increasingly important source of information about the public mood regarding issues such as elections, Brexit, stock market, etc. In this paper we focus on sentiment classification of Twitter data. Construction of sentiment classifiers is a standard text mining task, but here we address the question of how to properly evaluate them as there is no settled way to do so. Sentiment classes are ordered and unbalanced, and Twitter produces a stream of time-ordered data. The problem we address concerns the procedures used to obtain reliable estimates of performance measures, and whether the temporal ordering of the training and test data matters...

Air quality models are important for studying the impact of air pollutant on health conditions at a fine spatiotemporal scale. Existing work typically relies on area-specific, expert-selected attributes of pollution emissions (e,g., transportation) and dispersion (e.g., meteorology) for building the model for each combination of study areas, pollutant types, and spatiotemporal scales. In this paper, we present a data mining approach that utilizes publicly available OpenStreetMap (OSM) data to automatically generate an air quality model for the concentrations of fine particulate matter less than 2...
