S-Adenosyl-l-homocysteine hydrolase (SAHase) from the symbiotic bacterium Bradyrhizobium elkanii (BeSAHase) was crystallized in four ligand complexes with (i) mixed adenosine (Ado) and cordycepin (Cord; 3'-deoxyadenosine), (ii) adenine (Ade), (iii) Ado and (iv) mixed 2'-deoxyadenosine (2'-dAdo) and Ade. The crystal structures were solved at resolutions of 1.84, 1.95, 1.95 and 1.54 Å, respective...

BACKGROUND Adverse drug events (ADEs) are both common and costly. Most hospitals identify ADEs using spontaneous reporting, but this approach lacks sensitivity; chart review identifies more events but is expensive. Computer-based approaches to ADE identification appear promising, but they have not been directly compared with chart review and they are not widely used. OBJECTIVES To develop a c...

We determine N = 4 partition functions of N = 4 super Yang-Mills gauge theory for some ADE gauge groups on K3, under the assumption that they are holomorphic. Our partition functions satisfy the gap condition and Montonen-Olive duality at the same time, like the SU(N) partition functions of Vafa and Witten. As a result we find a close relation between Hecke operator and S-duality of N = 4 super...

n An), and |a| ∈ Z denotes the grading. The bracket and differential are required to respect the grading, in that for homogeneous elements, |[a, b]| = |a| + |b| while |∂a| = |a| − 1. The adjoint action of A on itself is given by ade(a) = [e, a] and acts on the grading by ade : An−→An+|e|. In this notation (2) and (3) can be rewritten as • (2) (Jacobi identity) ad[a,b] = [ada, adb] • (3) (Leibni...

We determine N = 4 partition functions on K3 for some ADE gauge groups, on the assumption that they are holomorphic. Our partition functions satisfy the gap condition and Montonen-Olive duality at the same time, like the SU(N) partition functions of Vafa and Witten. As a result, we reveal a close relation between Hecke operator and S-duality of N = 4 ADE gauge theory on K3.

Inspired by Cachazo, Katz and Vafa (“Geometric transitions and N = 1 quiver theories” (hep-th/0108120)), we examine representations of “N = 1 quivers” arising from string theory. We derive some mathematical consequences of the physics, and show that these results are a natural extension of Gabriel’s ADE theorem. Extending the usual ADE case that relates quiver representations to curves on surfa...

Dijkgraaf and Vafa have conjectured the correspondences between topological string theories, N = 1 gauge theories and matrix models. By the use of this conjecture, we calculate the quantum deformations of Calabi-Yau threefolds with ADE singularities from ADE multi-matrix models. We obtain the effective superpotentials of the dual quiver gauge theories in terms of the geometric engineering for t...

The presence of butanoic acid excess in the reaction media employed for the synthesis of a MOF with formula [Cu(2)(μ(3)-ade)(2)(μ(2)-OOC(CH(2))(2)CH(3))(2)](n) (ade: adeninate) leads to the formation of micelles that exert a template effect and provide a pronounced increase of its microporosity, doubling the intrinsic adsorption capacity of the pristine crystal network.

This paper describes a knowledge-based system for the non-destructive diagnostics of fac ade isolation. The system uses the fusion of information extracted from images obtained from two electromagnetic wavebands: from low-resolution IR images (320 240 pixels; 7.5–13 lm wavelength), and from highresolution visual RGB images (3264 2448 pixels; 0.39–0.75 lmwavelength). The fusion of the informatio...
