On (anti-)multiplicative generalized derivations

Glasnik matematički, 2012
Let $R$ be a semiprime ring and let $F, f : R \to R$ be (not necessarily additive) maps satisfying $F(xy)=F(x)y+xf(y)$ for all $x, y \in R.$ Suppose that there are integers $m$ and $n$ such that $F(uv)=mF(u)F(v)+nF(v)F(u)$ for all $u, v$ in some nonzero ideal $I$ of $R.$ Under some mild assumptions on $R, $ we prove that there exists $c \in C(I ...

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

FEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

Synthesis of Benzene Derivatives with Multiple Dichlorophosphino Groups

ChemPlusChem, 2023
AbstractThe chlorination of 1,2‐diphosphinobenzene with PCl5 to 1,2‐bis(dichlorophosphino)benzene was performed with high yields (93 %) despite the high number of P−H functions. The method was further applied to other phosphanes, enabling the first synthesis and complete characterization of 1,2,4‐tris(dichlorophosphino)benzene (89 % yield) and 1,2,4,5 ...

Renormalization of Critical Gaussian Multiplicative Chaos and KPZ Relation [PDF]

, 2013
Gaussian Multiplicative Chaos is a way to produce a measure on R[superscript d] (or subdomain of R[superscript d]) of the form e[superscript γX(x)]dx, where X is a log-correlated Gaussian field and γ∈[ 0, √2d) is a fixed constant.

Transcripts enriched in codons that trigger P‐site tRNA‐mediated mRNA decay possess stable mRNA

FEBS Open Bio, EarlyView.
PTMD codons were first described by Mendel et al. as mediators of an mRNA decay pathway dependent on the human protein CNOT3, homologous to yeast Not5. Our findings confirm that PTMD codons destabilize transcripts; however, unlike in yeast, the human pathway specifically targets and slightly destabilizes primarily stable mRNAs.

Impact of Asymptomatic Intracranial Hemorrhage on Outcome After Endovascular Stroke Treatment

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Endovascular treatment (EVT) achieves high rates of recanalization in acute large‐vessel occlusion (LVO) stroke, but functional recovery remains heterogeneous. While symptomatic intracranial hemorrhage (sICH) has been well studied, the prognostic impact of asymptomatic intracranial hemorrhage (aICH) after EVT is less certain ...

Fluid Biomarkers of Disease Burden and Cognitive Dysfunction in Progressive Supranuclear Palsy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Identifying objective biomarkers for progressive supranuclear palsy (PSP) is crucial to improving diagnosis and establishing clinical trial and treatment endpoints. This study evaluated fluid biomarkers in PSP versus controls and their associations with regional 18F‐PI‐2620 tau‐PET, clinical, and cognitive outcomes.

Stochastic Bifurcations of a Fractional-Order Vibro-Impact System Driven by Additive and Multiplicative Gaussian White Noises

Complexity, 2019
Stochastic fractional-order systems or stochastic vibro-impact systems can present rich dynamical behaviors, and lots of studies dealing with stochastic fractional-order systems or stochastic vibro-impact systems are available now, while the discussion ...

When in a multiplicative derivation additive? [PDF]

International Journal of Mathematics and Mathematical Sciences, 1990
Our main objective in this note is to prove the following. Suppose R is a ring having an idempotent element e(e ≠ 0,  e ≠ 1) which satisfies: urn:x-wiley:01611712:media:ijmm275743:ijmm275743-math-0001 If d is any multiplicative derivation of R, then d is additive.
