Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Subspace Codes Based on Partial Injective Maps of Vector Spaces Over Finite Fields

open access: yesIEEE Access, 2020
Subspace codes are widely used in error corrections of random network coding. In this article, subspace codes based on partial injective maps of vector spaces over finite fields are considered. Several bounds of the subspace codes (n, M, 2b, e)q based on

Definability with bounded number of bound variables

open access: yesInformation and Computation, 1989
A model-theoretic method for establishing the k-variable property is given in the paper. To study the k-variable property is important from the temporal logic point of view. A first-order theory satisfies the k- variable property if every formula is, under the theory, equivalent to a formula with at most k bound variables.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Theory of bounded groups and their bounded cohomology [PDF]

open access: yesPacific Journal of Mathematics, 1988
Bounded cohomology H can be defined for groups and for topological spaces. Recent work has shown that \(H^ *_ b(M)\) of a topological space M depends only on \(\pi _ 1(M)\). In this paper we consider a new concept - a bounded group - and thereby expand the definition of bounded cohomology.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Some New Bounds for Mathieu's Series [PDF]

open access: yes, 2007
In the paper, an upper bound and two lower bounds for Mathieu’s series are established, which refine to a certain extent a sharp double inequality obtained by Alzer-Brenner-Ruehr in 1998.
