Wettability of amorphous and nanocrystalline Fe78B13Si9 substrates by molten Sn and Bi

Description :

Abstract

The wettability of amorphous and annealing-induced nanocrystalline Fe78B13Si9 ribbons by molten Sn and Bi at 600 K was measured using an improved sessile drop method. The results demonstrate that the structural relaxation and crystallization in the...

Variational Principles for Minkowski Type Problems, Discrete Optimal Transport, and Discrete Monge-Ampere Equations

Description : In this paper, we develop several related finite dimensional variational principles for discrete optimal transport (DOT), Minkowski type problems for convex polytopes and discrete Monge-Ampere equation (DMAE). A link between the discrete optimal transport, discrete Monge-Ampere equation and the po...

Approximating Loops in a Shortest Homology Basis from Point Data

Description : Inference of topological and geometric attributes of a hidden manifold from its point data is a fundamental problem arising in many scientific studies and engineering applications. In this paper we present an algorithm to compute a set of loops from a point data that presumably sample a smooth man...

Dynamics of quantum entanglement in the reservoir with memory effects

Description : The non-Markovian dynamics of quantum entanglement is studied by the Shabani-Lidar master equation when one of entangled quantum systems is coupled to a local reservoir with memory effects. The completely positive reduced dynamical map can be constructed in the Kraus representation. Quantum entang...

Detection of competing DNA structures by thermal gradient gel electrophoresis: from self-association to triple helix formation by (G,A)-containing oligonucleotides

Description : Sequence-specific recognition of DNA can be achieved by triple helix-forming oligonucleotides that bind to the major groove of double-helical DNA. These oligonucleotides have been used as sequence-specific DNA ligands for various purposes, including sequence-specific gene regulation in the so-ca...

Position- and orientation-specific enhancement of topoisomerase I cleavage complexes by triplex DNA structures

Description : Topoisomerase I (Top1) activities are sensitive to various endogenous base modifications, and anticancer drugs including the natural alkaloid camptothecin. Here, we show that triple helix-forming oligonucleotides (TFOs) can enhance Top1-mediated DNA cleavage by affecting either or both the nicking a...

Comparison between CUUG and UUCG tetraloops: thermodynamic stability and structural features analyzed by UV absorption and vibrational spectroscopy

Description : CUUG loop is one of the most frequently occurring tetraloops in bacterial 16S rRNA. This tetraloop has a high thermodynamic stability as proved by previous UV absorption and NMR experiments. Here, we present our results concerning the thermodynamic and structural features of the 10mer 5′-r(GCG-CUUG-...

IMMUNOCAT—A Data Management System for Epitope Mapping Studies

Description : To enable rationale vaccine design, studies of molecular and cellular mechanisms of immune recognition need to be linked with clinical studies in humans. A major challenge in conducting such translational research studies lies in the management and integration of large amounts and various types of d...

(3S,4R)-3-Ethyl-4-hydr­oxy-3-(3-methoxy­phen­yl)-1-methyl­azepanium (2R,3R)-2,3-bis­(benzo­yloxy)-3-carboxy­propionate

Description : The crystal structure of the title compound, C16H26NO2 +·C18H13O8 −, is stabilized by an extensive network of classical N—H⋯O and O—H⋯O hydrogen bonding. The crystal structure also shows an ammonium-driven diastereo­isomerism.
