Effect of plasma resonances on dynamic characteristics of double graphene-layer optical modulator

open access: yes, 2012
We analyze the dynamic operation of an optical modulator based on double graphene-layer(GL) structure utilizing the variation of the GL absorption due to the electrically controlled Pauli blocking effect. The developed device model yields the dependences

Koszul Modules

open access: yesJournal of Pure and Applied Algebra, 2005
From the authors' introduction: Consider a noetherian local ring \(R\) with maximal ideal \(\mathcal M\) and residue field \(k\). Given a finitely generated \(R\)-module \(M\) and \(F\) its minimal free resolution, denote \(\text{lin}^R(F)\) the associated graded complex of \(F\) arising from the standard \(\mathcal M\)-adic filtration.

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

All-optical $\mathcal{PT}$-symmetric amplitude to phase modulator

open access: yes, 2015
We study electromagnetic field propagation through a planar three-waveguide coupler with linear gain and loss, in a configuration that is the optical analog of a quantum $\mathcal{PT}$-symmetric system, and provide its closed-form analytic propagator. At

β‐TrCP overexpression enhances cisplatin sensitivity by depleting BRCA1

open access: yesMolecular Oncology, EarlyView.
Low levels of β‐TrCP (Panel A) allow the accumulation of BRCA1 and CtIP, which facilitate the repair of cisplatin‐induced DNA damage via homologous recombination (HR) and promote tumor cell survival. In contrast, high β‐TrCP expression (Panel B) leads to BRCA1 and CtIP degradation, impairing HR repair, resulting in persistent DNA damage and apoptosis ...

Electron-phonon interaction in the t-J model

open access: yes, 2004
We derive a t-J model with electron-phonon coupling from the three-band model, considering modulation of both hopping and Coulomb integrals by phonons.
