Pfam is a large collection of protein families and domains. Over the past 2 years the number of families in Pfam has doubled and now stands at 6190 (version 10.0). Methodology improvements for searching the Pfam collection locally as well as via the web are described. Other recent innovations

Abstract: We analyze the transmission properties of double negative metamaterials (DNM). Numerical simulations, based on the transfer matrix algorithm, show that some portion of the electromagnetic wave changes its polarization inside the DNM structure. As the transmission properties depend

is also used to construct model libraries automatically from sequences in structural databases. We evaluate the SAM-T98 method with four datasets. Three of the test sets are fold-recognition tests, where the correct answers are determined by structural similarity. The fourth uses a curated database

Abstract. The paper presents a double structure constitutive model based on a generalized plasticity formalism. The behaviour of macrostructure, microstructure and their interactions are described. A coupled hydromechanical formulation is then presented that assumes no hydraulic equilibrium between

It is shown that the general plane section of a double structure on an integral curve CXP $ has a connected numerical character (that is, its Hilbert function is of decreasing type). The paper gives applications, particularly to the stability of the normal bundle of space curves. 1.

Abstract. Let Y be a smooth Enriques surface. A K3 carpet on Y is a locally Cohen-Macaulay double structure on Y with the same invariants as a smooth K3 surface (i.e., regular and with trivial canonical sheaf). The surface Y possesses an étale K3 double cover X π − → Y. We prove that π can

We suggest that the commonly accepted core structure of the 90 ± partial dislocation in Si may not be correct, and propose instead a period-doubled structure. We present local-density approximation, tightbinding, and classical Keating-model calculations, all of which indicate that the period-doubled

This paper reports on deformation characteristics and mechanical features of a tapered bottom tip of a cutting blade subjected to pushing loads. Whereas a 16 high carbon steel bevel blade of 0.16 mm tip thickness was experimentally investigated, various tapered bottom tips were numerically analyzed for effect of tip thickness and apex angle using elasto-plastic Finite Element Method. From this research, the transition point at which a large increase of crushed height also known as the shimming effect starts has been revealed. Major findings of this research have been (i) tip thickness moves the transition point without changing cutting direction stiffness, and (ii) up to a certain range the apex angle controls the lateral deflection mode of the blade.

The Lasso estimate for linear regression parameters can be interpreted as a Bayesian posterior mode estimate when the regression parameters have in-dependent Laplace (double-exponential) priors. Gibbs sampling from this pos-terior is possible using an expanded hierarchy with conjugate normal priors
