Intersubband-transition-induced phase matching [PDF]
Optics Letters, 1994 We suggest the use of the refractive-index changes associated with the intersubband transitions in quantum wells for phase matching in nonlinear materials. An improvement in the conversion efficiency of mid-IR second-harmonic generation by almost 2 orders of magnitude over non-phase-matched bulk GaAs is predicted.

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

The comparison of electrooptical properties of PDLC liquid-crystalline composites in visual and near-IR ranges [PDF]
Biuletyn Wojskowej Akademii Technicznej, 2017 Electrooptical properties of conventional Polymer-Dispersed Liquid Crystals (PDLC) composites were compared in visual and near-IR ranges for the electrically-induced light transmission effect.

Frontiers in Surgery, 2023 BackgroundNontraumatic osteonecrosis of the femoral head (ONFH) can be corticosteroid-induced, alcohol-induced, and idiopathic ONFH (IONFH). Although corticosteroid- and alcohol-induced ONFH has been investigated extensively regarding its relationship ...

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 ...

Colour and texture associations in voice-induced synaesthesia
Frontiers in Psychology, 2013 Voice-induced synaesthesia, a form of synaesthesia in which synaesthetic perceptions are induced by the sounds of people’s voices, appears to be relatively rare and has not been systematically studied.

Induced Matchings in Graphs of Degree at Most 4 [PDF]
SIAM Journal on Discrete Mathematics, 2016 Summary: For a graph \(G\), let \(\nu_s(G)\) be the strong matching number of \(G\). We prove the sharp bound \(\nu_s(G)\geq \frac{n(G)}{9}\) for every graph \(G\) of maximum degree at most 4 and without isolated vertices that does not contain a certain blown-up 5-cycle as a component.

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+.

Phase-matched electron–photon interactions enabled by 3D-printed helical waveguides
NanophotonicsThe Smith–Purcell effect enables electromagnetic radiation across arbitrary spectral ranges by phase-matching the diffraction orders of an optical grating with the near-field of a moving electron.
