The protein super‐family of medium‐chain alcohol dehydrogenases (and glutathione‐dependent formaldehyde dehydrogenase), polyol dehydrogenases, threonine dehydrogenase, archaeon glucose dehydrogenase, and eye lens reductase‐active ζ‐crystallins also includes Escherichia coli quinone oxidoreductase, Torpedo VAT‐1 protei…
ABSTRACT: We study the microphases of linear multiblock copolymers formed from monodisperse A- and B-type blocks in the limit in which the number of blocks is large. We find the lamellar, gyroid, hexagonal, and cubic microphases to be stable. Monocontinuous catenoid-lamellar and bicontinuous double-diamond phases are…
X-ray-photoemission spectra of 4d(${\mathit{N}}_{4,5}$) core level in heavy rare-earth elements are studied theoretically with the consideration of the 4d-4f4f(${\mathit{N}}_{4,5\mathrm{\ensuremath{-}}}$${\mathit{N}}_{6,7}$${\mathit{N}}_{6,7}$) super-Coster-Kronig decay process in the excited states. It is shown that…

Pyrolysis or combustion of plastics are of interest from different points of view: on the one hand polymers from which harmful substances may arise are involved in fires or are fed to incinerators; on the other hand plastic refuses are an alternative resource of energy or chemical raw materials. For designing recyclin…
The influence of internal stress on the magnetic anisotropy and the magnetostriction was investigated in sputter-deposited amorphous (Tb0.27Dy0.73)0.42Fe0.58 films. Films with tensile stress show in-plane anisotropy and giant magnetostriction of λ∥=400×10−6 at 1 T measured in a field parallel to the film plane at room…

The species composition of epipelic algal assemblages on intertidal mudflats was investigated at three sites in the Severn estuary, England, between March 1990 and February 1991. Diatoms were the dominant algal group, comprising greater than 95% of living cells in 100 out of 106 lens tissue samples. Euglenoid algae we…
By using a density-functional theory we establish the existence of a ferroelectric nematic phase in fluids consisting of spherical particles which interact with Lennard-Jones and dipolar forces. Our detailed analysis of the thermodynamic limit shows that for a polarized dipolar fluid within a single domain the free en…
The effect of tensile stress on the orientation and phenotype of arterial smooth muscle cells (SMCs) cultured in three-dimensional (3D) type I collagen gels was morphologically investigated. Ring-shaped hybrid tissues were prepared by thermal gelation of a cold mixed solution of type I collagen and SMCs derived from b…

Abstract Copolymers of L‐lactide with 15 or more mole % D‐lactide are amorphous, noncrystallizable hydrolytically degradable materials. These glassy materials are brittle in tension and bending. To make these materials suitable for use as load‐bearing devices in biomedical applications, toughness has to be enhanced. T…
A direct simulation of phonon-mediated heat transfer is described and preliminary results are reported. The method is derived from past work in simulating gas-dynamic flow and uses a linear array of cells for modeling a one-dimensional heat transfer problem. Central to the development of the technique is the Debye mod…

Type XII and XIV collagens are very large molecules containing three extended globular domains derived from the amino terminus of each alpha chain and an interrupted triple helix. Both collagens are genetically and immunologically unique and have distinct distributions in many tissues. These collagens localize near th…

We present the results of a detailed molecular-dynamics study of relaxation in the van der Waals system ortho-terphenyl in the supercooled regime. The molecule is described by a simple rigid three-site model, with interactions between different molecules of the Lennard-Jones form. We find that the long-time (\ensurema…
