On a waveguide with frequently alternating boundary conditions: homogenized Neumann condition
, 2010 We consider a waveguide modeled by the Laplacian in a straight planar strip. The Dirichlet boundary condition is taken on the upper boundary, while on the lower boundary we impose periodically alternating Dirichlet and Neumann condition assuming the ...

Structural biology of ferritin nanocages
FEBS 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 ...

Bruno Pini Mathematical Analysis Seminar, 2015 In this article, we show that under some coercive assumption on the complex-valued potential V(x), the derivatives of the resolvent of the non-selfadjoint Schröinger operator H = −∆ + V(x) satisfy some Gevrey estimates at the threshold zero.

Stability of the essential spectrum for 2D--transport models with Maxwell boundary conditions
, 2005 We discuss the spectral properties of collisional semigroups associated to various models from transport theory by exploiting the links between the so-called resolvent approach and the semigroup approach. Precisely, we show that the essential spectrum of

Rotationally resolved zero-kinetic-energy photoelectron spectrum of nitrogen
Physical Review A, 1992 Rotationally resolved zero-kinetic-energy (ZEKE) photoelectron spectra of the X $^{2}\mathrm{\ensuremath{\Sigma}}_{\mathrm{g}}^{+}$(${\mathrm{v}}^{+}$=0,1) \ensuremath{\leftarrow}X $^{1}\mathrm{\ensuremath{\Sigma}}_{\mathit{g}}^{+}$(v=0) bands of nitrogen have been recorded. The spectra show unexpected rotational-line intensities.

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

On Fuzzy Soft Linear Operators in Fuzzy Soft Hilbert Spaces
Abstract and Applied Analysis, 2020 Due to the difficulty of representing problem parameters fuzziness using the soft set theory, the fuzzy soft set is regarded to be more general and flexible than using the soft set.

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

On continuous and residual spectra of operators connected with iterative functional equations
Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2006 The sum type operator $F$, given by [ F lbrack varphi brack (x) : = displaystylesum^{infty}_{u = 0} 2^{-u} varphi (2^{u} x), ] will be considered on the space $D$ of bounded real functions, equipped with the supremum norm and on its ...

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+.
