A note on supersymmetry in noncommutative field theories
Abstract We show that a solution of the type IIB supergravity representing D3-branes in the presence of a 2-form background has 16 supersymmetries by explicitly constructing the transformation parameter of unbroken supersymmetry. This solution is dual to a noncommutative Yang–Mills theory in a certain limit.

SUPER WEYL ANOMALIES IN THE AdS/CFT CORRESPONDENCE
Anomalies of N=(4,4) superconformal field theories coupled to a conformal supergravity background in two dimensions are computed by using the AdS/CFT correspondence. We find that Weyl, axial gauge and super Weyl transformations are anomalous, while general coordinate, local Lorentz, vector gauge and local supertransformations are not. The coefficients of the anomalies show that the superconformal field theories have the central charge expected in the AdS/CFT correspondence.

Coupling of the BLG theory to a conformal supergravity background
A bstractThe Bagger-Lambert-Gustavsson theory is coupled to an off-shell D = 3, $ \mathcal{N}=8 $ conformal supergravity background. Local transformation laws of the conformal supergravity multiplet are obtained from those of the D = 4, $ \mathcal{N}=8 $ SO(8) gauged super-gravity. The complete Lagrangian and local transformation laws of the coupled theory are obtained. As an application the supercurrent multiplet in a flat background is obtained.

Conformal supergravity from the AdS / CFT correspondence
Construction of a five-dimensional conformal supergravity (D = 5 CSG) is attempted by applying the AdS/CFT correspondence to the F(4) AdS supergravity in six dimensions. As a first step, local transformation laws of D = 5 CSG have been established, from which the Weyl weights of the various fields in D = 5 can be predicted. (C) 2000 Elsevier Science B.V.

Comments on higher derivative terms for the tachyon action
We consider the open string tachyon action in a world-sheet sigma model approach. We present explicit calculations up to order 8 in derivatives for the bosonic string, and mimic these to order 6 for the superstring, including terms with multiple derivatives acting on the tachyon field. We reproduce lower derivative terms obtained elsewhere, and speculate on the role of the world-sheet contact terms regularizing the action for the superstring tachyon.

A Thick and Large Active Area Si(Li) Detector
A 5 inch diameter, 3mm thick silicon detector has been fabricated using a nondetector grade crystal. The detector characteristics of the silicon detector were examined with infrared light as well as a hadron beam.
