Discrete Mathematics, 1988 The author deals with the comparison of the following two fundamental metrical properties of a network: (a) it is a tree if and only if its metric is convex, and (b) it decomposes into finitely many treelike segments on which the metric is convex.

Ultrametricity and metric betweenness in tangent spaces to metric spaces
P-Adic Numbers, Ultrametric Analysis, and Applications, 2010 The paper deals with pretangent spaces to general metric spaces. An ltrametricity criterion for pretangent spaces is found and it is closely related to the metric betweenness in the pretangent spaces.

FEBS Letters, EarlyView.This work presents the characterization of MvoDUF2193, a Methanococcus voltae (Mvo) protein from the domain of unknown function (DUF) 2193 family. We demonstrate that MvoDUF2193 binds a single [4Fe–4S] cluster per subunit and that cluster occupancy regulates the transition from an apo tetramer to a [4Fe–4S] monomeric form. This structural transition is

Approximation and Schur properties for Lipschitz free spaces over compact metric spaces
, 2015 We prove that for any separable Banach space $X$, there exists a compact metric space which is homeomorphic to the Cantor space and whose Lipschitz-free space contains a complemented subspace isomorphic to $X$.

Neutrophil deficiency increases T cell numbers at the site of tissue injury in mice
FEBS Letters, EarlyView.In wild‐type mice, injury or acute inflammation induces neutrophil influx followed by macrophage accumulation. Mcl1ΔMyelo (neutrophil‐deficient) mice lack neutrophils, and in response to muscle injury show fewer macrophages and exhibit strikingly elevated T‐cell numbers, primarily non‐conventional “double‐negative” (DN) αβ and γδ T cells.

Functional role and folding properties of the glucan‐binding domain of oral bacterial glucansucrase
FEBS Letters, EarlyView.The role of the glucan‐binding domain in Streptococcus sobrinus glucansucrase was examined, focusing on its impact on enzymatic activity, dextran binding, and structural stability of deletion mutants and a circularly permuted protein. Our research revealed that glucosyl transfer efficiency is linked to cooperative interdomain folding.

Topology and its Applications, 2014 Let $X$ be an unbounded metric space, $B(x,r) = \{y\in X: d(x,y) \leqslant r\}$ for all $x\in X$ and $r\geqslant 0$. We endow $X$ with the discrete topology and identify the Stone- ech compactification $ X$ of $X$ with the set of all ultrafilters on $X$.

FEBS Letters, EarlyView.The yeast mitoribosome assembly factor Rsm22 contains a [4Fe‐4S] cluster that is matured by the mitochondrial iron–sulfur cluster assembly (ISC) machinery. Defects in ISC components result in impaired mitochondrial protein synthesis due to a mitoribosome assembly defect.

Topographic Gromov-Hausdorff quantum Hypertopology for Quantum Proper Metric Spaces
, 2014 We construct a topology on the class of pointed proper quantum metric spaces which generalizes the topology of the Gromov-Hausdorff distance on proper metric spaces, and the topology of the dual propinquity on Leibniz quantum compact metric spaces.

The contraction principle for mappings on a metric space with a graph
, 2007 We give some generalizations of the Banach Contraction Principle to mappings on a metric space endowed with a graph. This extends and subsumes many recent results of other authors which were obtained for mappings on a partially ordered metric space.
