Local area networks for microcomputers
Abstract This paper analyses the ways in which modern high performance Local Area Networks (LANs) can be of use to microcomputers. It discusses some of the basic concepts of LANs, with special reference to international standards. It then presents ways in which LANs may be connected to, and used with microcomputers. Examples are given of existing applications.

Cp Violation In Models With Two And Three Scalar Doublets
We reanalyze the two- and three-scalar (Higgs) doublet models with spontaneous CP violation. We show that the two-Higgs doublet model of T.D. Lee can be made consistent with the recent measurements of e′/e provided the ΔS = 2 amplitudes receive important contributions from neutral Higgs exchanges. The sign of e′/e is positive in this model. The main part of our paper constitutes a new calculation of CP violation in the three-Higgs doublet model with natural flavor conservation. We find in contrast to previous analyses that this model is consistent with the experimental value of e′/e provided an interesting hierarchy among the vacuum expectation values present in the model is assumed. e′/e can have both signs in this model and is typically ±0.005. Simultaneously ΔM(K1 − Ks), the e-parameter and the electric dipole moment of the neutron are consistent with the experimental data.

On the Breakdown of Chiral Symmetries in Supersymmetric {QCD}
We investigate the breakdown of chiral symetries in supersymmetric QCD with N colours and M flavours, using anomaly consistency conditions and an effective lagrangian approach. For M N, however, one needs at least unbroken SU(N)V × SU(M − N)R × SU(M − N)L × U(1) × U(1) to arrive at a consistent picture.

Gravitation And Symmetry Breaking
Among the possible vacua, quantum gravity within the stationary phase approximation selects the vacuum with vanishing cosmological constant. Classical background gravity coupled to matter renders the highest Higgs potential minimum stable, allowing for spontaneous supersymmetry breaking. The influence of the non-renormalizability of supergravity on the symmetry breaking pattern is studied.

Trace anomalies and the Delta I = 1/2 rule
Trace Anomaly Dominance in weak $K$-decays successfully reproduces the $\Delta I = {1\over 2}$ selection rule results, as observed in $K_S \to \pi\pi, K_L \to \pi\pi\pi, K_S \to \gamma\gamma$ and $K_L \to \pi^0 \gamma\gamma$. Comment: 10 pages, no figure

Current-current operator evolution in the chiral limit
Abstract We consider the strong interaction corrections to current-current hadronic operators in the chiral limit. High-momentum contributions are computed in perturbative QCD with massless quarks while low-momentum contributions are estimated in a truncated non-linear σ-model for massless pseudoscalars. In the large- N approximation, the ambiguity on the momentum matching around the confining scale is removed by using the effective color-singlet gauge boson exchanged between the two currents as a universal probe.
