Visible Light-Responsive Photocatalytic Activity of Boron Nitride Incorporated Composites

open access: yesFrontiers in Chemistry, 2018
Photocatalysts are essential to promote the highly efficient applications of solar energy in water splitting and/or the degradation of organic contaminations.

Analytical thermodynamics of a strongly attractive three-component Fermi gas in one dimension

open access: yes, 2010
Ultracold three-component atomic Fermi gases in one dimension are expected to exhibit rich physics due to the presence of trions and different pairing states.

A TV-Gaussian prior for infinite-dimensional Bayesian inverse problems and its numerical implementations [PDF]

open access: yes, 2016
Many scientific and engineering problems require to perform Bayesian inferences in function spaces, in which the unknowns are of infinite dimension. In such problems, choosing an appropriate prior distribution is an important task.

A Hybrid Reproducing Kernel Particle Method for Three-Dimensional Helmholtz Equation

open access: yesMathematics
The reproducing kernel particle method (RKPM) is one of the most universal meshless methods. However, when solving three-dimensional (3D) problems, the computational efficiency is relatively low because of the complexity of the shape function.

Graded Computing

open access: yesСовременные информационные технологии и IT-образование, 2019
Calculations with a large amount of data (or data of a large dimension) are usually reduced to sets of calculations with fairly small amounts of them.

First results for the Coulomb gauge integrals using NDIM [PDF]

open access: yes, 2000
The Coulomb gauge has at least two advantadges over other gauge choices in that bound states between quarks and studies of confinement are easier to understand in this gauge.

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Electrostatics in Fractal Geometry: Fractional Calculus Approach

open access: yes, 2011
The electrostatics properties of composite materials with fractal geometry are studied in the framework of fractional calculus. An electric field in a composite dielectric with a fractal charge distribution is obtained in the spherical symmetry case. The

A matrix formulation for small-x singlet evolution [PDF]

open access: yes, 2007
We propose a matrix evolution equation in (x,kt)-space for flavour singlet, unintegrated quark and gluon densities, which generalizes DGLAP and BFKL equations in the relevant limits.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These
