Cubic Graphs with Total Domatic Number at Least Two

Discussiones Mathematicae Graph Theory, 2018
Let G be a graph with no isolated vertex. A total dominating set of G is a set S of vertices of G such that every vertex is adjacent to at least one vertex in S.

The identifying code, the locating-dominating, the open locating-dominating and the locating total-dominating problems under some graph operations [PDF]

, 2019
International audienceThe problems of determining minimum identifying, locating-dominating, open locating-dominating or locating total-dominating codes in a graph G are variations of the classical minimum dominating set problem in G and are all known to ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Chemical Reaction Optimization for Minimum Weight Dominating Set

, 2023
Dominating set of a graph can be defined as the set of vertices that can cover all other vertices of the graph. The minimum weight dominating set (MWDS) is the minimum number of vertices in the dominating set with minimum total weight.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

The pyruvate generator is a common phenomenon in mitochondria from different rat and mouse brain regions

FEBS Letters, EarlyView.
The pyruvate generator, which causes activation of respiration by extra‐mitochondrial Ca2+, is also present and functional in rat brainstem mitochondria, as it is in other brain regions. This finding is confirmed by experiments with a fully reconstituted malate–aspartate shuttle (MAS).

The Numerical Invariants concerning the Total Domination for Generalized Petersen Graphs

Journal of Mathematics, 2020
A subset S of VG is called a total dominating set of a graph G if every vertex in VG is adjacent to a vertex in S. The total domination number of a graph G denoted by γtG is the minimum cardinality of a total dominating set in G.

On the maximum number of minimum total dominating sets in forests

Discrete Mathematics & Theoretical Computer Science, 2019
We propose the conjecture that every tree with order $n$ at least $2$ and total domination number $\gamma_t$ has at most $\left(\frac{n-\frac{\gamma_t}{2}}{\frac{\gamma_t}{2}}\right)^{\frac{\gamma_t}{2}}$ minimum total dominating sets. As a relaxation of this conjecture, we show that every forest $F$ with order $n$, no isolated vertex, and total ...

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

FEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified
