Anisotropic Memristive Switching in NbOCl2 Enabled by Directional Oxygen Ion Migration

Advanced Science, EarlyView.
This study investigates strongly orientation‐dependent memristive switching in anisotropic NbOCl2, observed exclusively along the in‐plane c‐axis. The switching originates from direction‐selective oxygen‐ion migration and vacancy propagation that modulate the Pd/NbOCl2 Schottky barrier, enabling short‐term plasticity.

Transversal Hamilton Paths and Cycles

SIAM Journal on Discrete Mathematics
Abstract. Given a collection [Formula: see text] of graphs on the common vertex set [Formula: see text] of size [Formula: see text], an [Formula: see text]-edge graph [Formula: see text] with vertices in [Formula: see text] is a transversal in [Formula: see text] if there exists a bijection [Formula: see text] such that [Formula: see ...

The Natural Product Corramycin Acts as a DNA Gyrase Poison and Overcomes Fluoroquinolone Resistance in Mycobacterium tuberculosis

Advanced Science, EarlyView.
Corramycin, a myxobacterial natural product antibiotic, exhibits potent bactericidal activity against multidrug‐resistant Mycobacterium tuberculosis. The compound hijacks bacterial transporters such as BacA and OppABCD to enter the cell and inhibits DNA synthesis through a previously unrecognized mode of DNA gyrase poisoning, locking the enzyme in an ...

k-Ordered Hamilton cycles in digraphs

Journal of Combinatorial Theory, Series B, 2008
Given a digraph D, the minimum semi-degree of D is the minimum of its minimum indegree and its minimum outdegree. D is k-ordered Hamiltonian if for every ordered sequence of k distinct vertices there is a directed Hamilton cycle which encounters these vertices in this order.

A Rare De Novo Missense Mutation in IFT122 Confers a Genetic Susceptibility Factor of Idiopathic Pediatric Uveitis Via Trio‐based Whole‐Exome Sequencing

Advanced Science, EarlyView.
A rare de novo IFT122‐A773E variant is identified in idiopathic pediatric uveitis and shown to exacerbate retinal inflammation and barrier dysfunction. Mechanistically, the variant enhances IFT43 interaction, elevates calcium signaling, and activates the MEK/ERK/FRA1 axis, revealing a previously unrecognized cilia‐associated pathway that may increase ...

Counterexample to a conjecture on Hamilton cycles

Discrete Mathematics, 1987
We disprove the following conjecture [cf. ''Unsolved problems'', Cycles in graphs, Workshop Simon Fraser Univ., Burnaby/Can. 1982, Ann. Discrete Math. 27, 461-468 (1985)]: Let G be a 2-connected graph with minimum degree n on atmost 3n-2 vertices. Then G is Hamiltonian if it has a 2- factor.

A Note on Cycles in Locally Hamiltonian and Locally Hamilton-Connected Graphs

Discussiones Mathematicae Graph Theory, 2020
Let 𝒫 be a property of a graph. A graph G is said to be locally 𝒫, if the subgraph induced by the open neighbourhood of every vertex in G has property 𝒫. Ryjáček conjectures that every connected, locally connected graph is weakly pancyclic.

m6A‐Driven Pexophagy Triggers Placental Ferroptosis to Impair Fetal Growth Upon Environmental Stress

Advanced Science, EarlyView.
Prenatal environmental stress exposure promotes m6A modification to drive PEX2‐dependent pexophagy, thereby causing placental ferroptosis and FGR. ABSTRACT The role and underlying mechanisms of placental ferroptosis in fetal growth restriction (FGR) induced by environmental stress remain poorly understood.

Hamilton cycles in Euler tour graph

Journal of Combinatorial Theory, Series B, 1986
The Euler tour graph of an Euler graph G denoted by \(E_ u(G)\) is the undirected simple graph defined as follows: The vertices of \(E_ u(G)\) are the Euler tours of G and two Euler tours E and F are adjacent in \(E_ u(G)\) if they can be transformed from each other by a K- transformation which was introduced by Kotzig in 1966.
