Commutable Matrix-Valued Functions and Operator-Valued Functions

Communications in Advanced Mathematical Sciences, 2020
A simple expression is established for an analytic commutable matrix-valued function. Then a characterization of two by two functional commutative matrices is proven.

Resolving Resolvins

Chemistry & Biology, 2013
In this issue of Chemistry & Biology, Dalli and colleagues report the chemical structures of resolvin D3 (RvD3) and aspirin-triggered RvD3, derived from the ω3-fatty acid docosahexaenoic acid. These compounds have a specific temporal appearance within inflammation resolution and display anti-inflammatory and proresolving properties.

Resolvability and Strong Resolvability in the Direct Product of Graphs [PDF]

Results in Mathematics, 2016
Given a connected graph $G$, a vertex $w\in V(G)$ distinguishes two different vertices $u,v$ of $G$ if the distances between $w$ and $u$ and between $w$ and $v$ are different. Moreover, $w$ strongly resolves the pair $u,v$ if there exists some shortest $u-w$ path containing $v$ or some shortest $v-w$ path containing $u$.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Properties of the resolvent of singular q-Dirac operators

Electronic Journal of Differential Equations, 2020
In this article, we investigate the resolvent operator of a singular q-Dirac system. We obtain an integral representations for the resolvent of this system, in terms of the spectral function.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

The significant contribution of stochastic forcing to nonlinear energy transfer in resolvent analysis

Theoretical and Applied Mechanics Letters
Nonlinear energy transfer is represented through eddy viscosity and stochastic forcing within the framework of resolvent analysis. Previous investigations estimate the contribution of eddy-viscosity-enhanced resolvent operator to nonlinear energy ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Resolvable, not maximally resolvable spaces

Topology and its Applications, 1997
According to \textit{J. G. Ceder} [Fundam. Math. 55, 87-93 (1964; Zbl 0139.40401)] following E. Hewitt (1963), a space \(X= (X,{\mathcal T})\) is said to be \(\kappa\)-resolvable if \(X\) is the union of \(\kappa\)-many pairwise disjoint dense subsets; and \(X\) is maximally resolvable if \(X\) is \(\Delta(X)\)-resolvable, where \(\Delta(X)= \min\{| U|:

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
