The Role of $B_s \to K \pi$ in Determining the Weak Phase $\gamma$

open access: yes, 2000
The decay rates for $B^0 \to K^+ \pi^-$, $B^+ \to K^0 \pi^+$, and the charge-conjugate processes were found to provide information on the weak phase $\gamma \equiv {\rm Arg}(V_{ub}^*)$ when the ratio $r$ of weak tree and penguin amplitudes was taken from

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

open access: yesFEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

Can $X(5568)$ be described as a $B_s\pi$, $B\bar{K}$ resonant state?

open access: yes, 2016
The D0 Collaboration has recently seen a resonant-like peak in the $B_s\pi$ invariant mass spectrum, claimed to be a new state called $X(5568)$. Using a $B_s\pi$--$B\bar{K}$ coupled channel analysis, implementing unitarity, and with the interaction derived from Heavy Meson Chiral Perturbation Theory, we are able to reproduce the reported spectrum, with

Quasi-elastic knockout of pions and kaons from nucleons by high-energy electrons and quark microscopy of "soft" meson degrees of freedom in the nucleon

open access: yes, 2004
Electro-production of pions and kaons at the kinematics of quasi-elastic knockout (which is well known in the physics of atomic nucleus and corresponds to the $t$-pole diagram) is proposed for obtaining their momentum distribution (MD) in various ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Adolescents’ Psychological Inflexibility as a Mediator Between Maternal Inflexibility and Internalizing Problems

open access: yesChildren
Background/Objectives: Internalizing disorders are highly prevalent during adolescence. Previous research has shown that psychological inflexibility (PI) in both adolescents and their parents contributes to internalizing problems.

Determination of differential pencils with impulse from interior spectral data

open access: yesBoundary Value Problems, 2019
In this paper, we are concerned with the inverse spectral problems for differential pencils defined on [0,π] $[0,\pi ]$ with an interior discontinuity. We prove that two potential functions are determined uniquely by one spectrum and a set of values of ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Study of B c + → χ c π + $$ {B}_c^{+}\to {\chi}_c{\pi}^{+} $$ decays

open access: yesJournal of High Energy Physics
A study of B c + → χ c π + $$ {B}_c^{+}\to {\chi}_c{\pi}^{+} $$ decays is reported using proton-proton collision data, collected with the LHCb detector at centre-of-mass energies of 7, 8, and 13 TeV, corresponding to an integrated luminosity of 9 fb −1 ...
