Quantum number projection at finite temperature via thermofield dynamics

, 2004
Applying the thermo field dynamics, we reformulate exact quantum number projection in the finite-temperature Hartree-Fock-Bogoliubov theory. Explicit formulae are derived for the simultaneous projection of particle number and angular momentum, in ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS 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+.

Approximations of solutions for a class of conditionally well-posed integro-differential equations

Учёные записки Казанского университета: Серия Физико-математические науки
In this article, for a specific class of conditionally well-posed integro-differential equations in a novel pair of weighted Sobolev spaces, an alternative method for constructing approximations (particularly finite-dimensional ones) to the solution of ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Numerical analysis of low-Reynolds-number flow past an array of pillars with surface slip

Nihon Kikai Gakkai ronbunshu
In the development of micro- and nano-fluidic devices incorporating nanopillar structures to create nanoscale confined flow paths, it is important to consider the slip velocity on the pillar surface, which reflects the local wettability.

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

FEBS 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

A Projection Model of Neutrosophic Numbers for Multiple Attribute Decision Making of Clay-Brick Selection [PDF]

Neutrosophic Sets and Systems, 2016
Brick plays a significant role in building construction. So we should use the effective mathematical decision making tool to select quality clay-bricks for building construction.
