Potassium trihydrogen dioxalate dihydrate (KTO) nonlinear optical (NLO) single crystal for optical limiting application

Results in Physics, 2023
In nonlinear optics, optical power limiting (OPL) compounds are known to be an important class of materials because it has the ability to protect the optical sensor components as well as human eyes from the abrupt intense laser power. Here, we have grown

Turbulent Velocity Structure in Molecular Clouds

, 2002
We compare velocity structure in the Polaris Flare molecular cloud at scales ranging from 0.015 pc to 20 pc to simulations of supersonic hydrodynamic and MHD turbulence computed with the ZEUS MHD code.

Acid Red 114 Removal Using a Low-Cost Material: Experimental Study and Statistical Physics Modeling [PDF]

Iranian Journal of Chemistry & Chemical Engineering
An eco-friendly and cost-effective biosorbent has been developed for the efficient elimination of acid red 114 dye from aqueous media. Batch studies were carried out to determine the effects of various operating parameters, namely the effect of ...

Structure of a Ty1 restriction factor reveals the molecular basis of transposition copy number control

Nature Communications, 2021
In Saccharomyces cerevisiae, unchecked proliferation of Ty1 retrotransposons is controlled by the process of copy number control (CNC), which requires the p22/p18 protein, translated from an internal transcript within the Ty1 GAG gene.

Effect of Intra-molecular Disorder and Inter-molecular Electronic Interactions on the Electronic Structure of Poly-p-Phenylene Vinylene (PPV)

, 2007
We investigate the role of intra-molecular conformational disorder and inter-molecular electronic interactions on the electronic structure of disorder clusters of poly-p-phenylene vinylene (PPV) oligomers.

Glucosamine-induced endoplasmic reticulum stress attenuates apolipoprotein B100 synthesis via PERK signaling

Journal of Lipid Research, 2009
Glucosamine impairs hepatic apolipoprotein B100 (apoB100) production by inducing endoplasmic reticulum (ER) stress and enhancing cotranslational and posttranslational apoB100 degradation (Qiu, W., R. K. Avramoglu, A. C. Rutledge, J. Tsai, and K.

An allosteric conduit facilitates dynamic multisite substrate recognition by the SCFCdc4 ubiquitin ligase

Nature Communications, 2017
The WD40 domain of the SCFCdc4ubiquitin ligase targets substrates via multiple phosphorylated degron motifs. The authors define a second degron-binding WD40 pocket that imparts a negative allosteric effect on binding to the primary pocket, and thereby ...

NLRP10 engages oxidized DNA through a Schiff-base mechanism and dissociates from NLRP3 upon inflammasome activation

Communications Biology
Mitochondrial DNA release into the cytosol is a critical event in innate immune activation, often acting as a damage-associated molecular pattern (DAMP) that triggers inflammasome assembly.

Supersonic turbulence and structure of interstellar molecular clouds [PDF]

, 2002
The interstellar medium (ISM) provides a unique laboratory for highly supersonic, driven hydrodynamics turbulence. We present a theory of such turbulence, confirm it by numerical simulations, and use the results to explain observational properties of ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
