Renormalizability of the local composite operator Aμ2 in linear covariant gauges [PDF]
Physics Letters B, 2003 The local composite operator $A_ ^{2}$ is analysed within the algebraic renormalization in Yang-Mills theories in linear covariant gauges. We establish that it is multiplicatively renormalizable to all orders of perturbation theory. Its anomalous dimension is computed to two-loops in the MSbar scheme.

FEBS 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.

Multivariate Polya-Schur classification problems in the Weyl algebra
, 2009 A multivariate polynomial is {\em stable} if it is nonvanishing whenever all variables have positive imaginary parts. We classify all linear partial differential operators in the Weyl algebra $\A_n$ that preserve stability.

Cyclic behavior of linear fractional composition operators [PDF]
, 2001 Let \(\mathbb{C}\) denote the plane of complex numbers, and for real number \(v\), and analytic functions \(f\), \(g\) representable as \[ f(z)= \sum\{a_nz^n, n= 0,1,2,\dots\},\quad g(z)= \sum\{b_n z^n, n= 0,1,\dots,\}, \] let \((f|g)_v= \sum\{(a_n b_n(n+ 1)^{2v}, n= 0,1,\dots\}\), \(\|f\|^2_v= \sum\{|a_n|^2(n+ 1)^{2v}, n= 0,1,2,\dots\}\).

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

The inner kernel theorem for a certain Segal algebra
, 2018 The Segal algebra ${\textbf{S}}_{0}(G)$ is well defined for arbitrary locally compact Abelian Hausdorff (LCA) groups $G$. Despite the fact that it is a Banach space it is possible to derive a kernel theorem similar to the Schwartz kernel theorem, of ...

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.

A simple and low-cost integrative sensor system for methane and hydrogen measurement
Sensors International, 2020 Energy production by methanization or gasification of biomass is dependant on the chemical composition of the gas generated. The resistive sensors based on semiconductor metal oxides, like the MQ series sensors, are inexpensive and frequently used in gas
