Let $G$ be a tamely ramified reductive $p$-adic‎ ‎group‎. ‎We study distinction of a class of irreducible admissible representations‎ ‎of $G$ by the group of fixed points $H$ of an involution‎ ‎of $G$‎. ‎The representations correspond to $G$-conjugacy classes of‎ ‎pairs $(T,phi)$‎, ‎where $T$ is a‎ ‎tamely ramified maximal torus of $G$ and $phi$ is a quasicharacter‎ ‎of $T$ whose restriction t...

Phagosome-lysosome membrane fusion is a highly regulated event that is essential for intracellular killing of microorganisms. Functionally, it represents a form of polarized regulated secretion, which is classically dependent on increases in intracellular ionized calcium ([Ca2+]i). Indeed, increases in [Ca2+]i are essential for phagosome-granule (lysosome) fusion in neutrophils and for lysosoma...

We initiate the study of higher dimensional topological finiteness properties monoids. This is done by developing theory monoids acting on CW complexes. For this we establish foundations $M$-equivariant homotopy where $M$ a discrete monoid. projective $M$-CW complexes prove several fundamental results such as extension and lifting property, which use to Whitehead theorems. define left equivaria...

For a given pseudo-Brewster angle phi(pB) of minimum reflectance |r(p)| of p-polarized light at a dielectric-conductor interface, the second-Brewster angle phi(2B) of minimum reflectance ratio |rho|=|r(p)|/|r(s)| of the p and s polarizations is determined for all possible values of the complex relative dielectric function epsilon that lead to the same phi(pB). The difference phi(2B)-phi(pB) is ...

In this paper, we address the additivity of n-multiplicative isomorphisms and derivations on gamma rings. We proved that, if $${{\mathfrak {M}}}\, $$ is a $$\Gamma -ring satisfying some conditions, then any isomorphism $$\left( \varphi , \phi \right) onto an arbitrary ring additive.
