Independent Bondage Number in Planar Graphs Under Girth Constraints

open access: yesMathematics
Given a finite, simple, connected graph G with at least one edge, the independent bondage number bi(G) of G is the minimum size of an edge set, such that its deletion results in a graph with a strictly larger independent domination number than that of G.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Neighbor Full Sum Distinguishing Total Coloring of Planar Graphs with Girth at Least 5

open access: yesAxioms
A neighbor full sum distinguishing total coloring of a graph G is a proper k-total coloring ϕ such that no two adjacent vertices u and v satisfy ω(u)≠ω(v), where ω(v)=ϕ(v)+∑e∋vϕ(e)+∑u∈N(v)ϕ(u) and N(v)={u|uv∈E(G)}.

Effect of secondary discharge on the repeatability of contact discharge method

open access: yesElectronics Letters, 2017
Submillimetre gaps caused by buttons, switches exist in the electronic device. IEC 61000‐4‐2 indicates that contact discharge method will be used if these floating metals could be touched in its normal use. Secondary discharge happens when conduct contact discharge on these floating metals.

Changes in Immune‐Inflammation Status and Acute Ischemic Stroke Prognosis in Prospective Cohort

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Inflammation is a critical risk factor for poor outcomes in cerebral infarction. Prior studies focused primarily on baseline inflammation status, neglecting dynamic longitudinal changes. We try to investigate the association between immune‐inflammation status alterations and stroke prognosis, and evaluated three systemic biomarkers'
