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.

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.

Numerical Range of Two Operators in Semi-Inner Product Spaces
Abstract and Applied Analysis, 2012 In this paper, the numerical range for two operators (both linear and nonlinear) have been studied in semi-inner product spaces. The inclusion relations between numerical range, approximate point spectrum, compression spectrum, eigenspectrum, and ...

On some numerical characteristics of operators
Arab Journal of Mathematical Sciences, 2015 We investigate some numerical characteristics of Toeplitz operators including the numerical range, maximal numerical range and maximal Berezin set. Further, we establish an inequality for the Berezin number of an arbitrary operator on the Hardy–Hilbert ...

Numerical ranges as circular discs
Applied Mathematics Letters, 2011 For a finite matrix \(A\) of the form \(\begin{pmatrix} aI& B \\ 0 &C\end{pmatrix}\) is proved that if its numerical range \(W(A)\) is a~circular disc centered at~\(a\), then \(a\) must be an eigenvalue of~\(C\). As a~consequence, the author shows, for any finite matrix~\(A\), that: (a)~if \(\partial W(A)\) contains a~circular disc, then its center is ...

On the boundary of the numerical range of a matrix
Applied Mathematics Letters, 2010 Every diagonal element of a~matrix~\(A\) is known to lie in the numerical range \(W(A)\) of~\(A\). A~characterization of real \(2\times 2\) matrices~\(A\) for which a~diagonal entry is a~boundary point of its numerical range is obtained, and is as follows: the diagonal entry~\(a_{11}\) is a~boundary point of the numerical range of~\(A\) if and only if \

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 ...

Numerical range for random matrices
, 2014 We analyze the numerical range of high-dimensional random matrices, obtaining limit results and corresponding quantitative estimates in the non-limit case. For a large class of random matrices their numerical range is shown to converge to a disc.
