Another Proof of the Generalized Tutte—Berge Formula for f $f$‐Bounded Subgraphs

Journal of Graph Theory, EarlyView.
ABSTRACT Given a nonnegative integer weight f ( v ) $f(v)$ for each vertex v $v$ in a multigraph G $G$, an f $f$‐bounded subgraph of G $G$ is a multigraph H $H$ contained in G $G$ such that d H ( v ) ≤ f ( v ) ${d}_{H}(v)\le f(v)$ for all v ∈ V ( G ) $v\in V(G)$.

The Independence Ratio of 4‐Cycle‐Free Planar Graphs

Journal of Graph Theory, EarlyView.
ABSTRACT We prove that every n $n$‐vertex planar graph G $G$ with no triangle sharing an edge with a 4‐cycle has independence ratio n ∕ α ( G ) ≤ 4 − ε $n\unicode{x02215}\alpha (G)\le 4-\varepsilon $ for ε = 1 ∕ 30 $\varepsilon =1\unicode{x02215}30$. This result implies that the same bound holds for 4‐cycle‐free planar graphs and planar graphs with no ...

You, Me, and the AI: The Role of Third‐Party Human Teammates for Trust Formation Toward AI Teammates

Journal of Organizational Behavior, EarlyView.
ABSTRACT As artificial intelligence (AI) becomes increasingly integrated in teams, understanding the factors that drive trust formation between human and AI teammates becomes crucial. Yet, the emergent literature has overlooked the impact of third parties on human‐AI teaming.

Heat and Cold Waves in Brazil: An ERA5‐Based Analysis of Trends and Seasonality (1980–2024)

International Journal of Climatology, EarlyView.
This study uses ERA5 reanalysis data to assess changes in extreme heat and cold events across Brazil from 1980 to 2024. Results reveal a sharp increase in heatwave frequency and a general decline in coldwave occurrences, though regional variations are substantial.

Development of simple predictive models of tooth loss in the community setting

Journal of Periodontology, EarlyView.
Abstract Background A simple tool for predicting the risk of tooth loss is considered valuable for the implementation of early preventive measures in community settings. This study aimed to establish a simple predictive model for tooth loss in a community‐dwelling Japanese population.

An Integrated Prehospital Point‐of‐Care Lung Ultrasound Protocol for Patients with Dyspnea

Journal of Ultrasound in Medicine, EarlyView.
We present a time‐efficient, clinically integrated lung ultrasound protocol tailored for prehospital use by providers not yet routinely using ultrasound. Specifically designed to support the recognition of pneumothorax and interstitial syndrome, the protocol emphasizes operational feasibility, spectrum‐based diagnostic reasoning, and strict time ...

Observation of Linear and Nonlinear Light Trapping on Topological Dislocations

Laser &Photonics Reviews, EarlyView.
Topological dislocations are global lattice defects found in various systems ranging from crystals to photonic lattices. This work reports the first observation at optical frequencies of linear modes with tunable localization bound to edge dislocations and their nonlinear counterparts ‐ dislocation solitons. These results reveal an intriguing interplay

Nonlinear Resonance Modulation in Single‐Crystalline VO2‐Integrated Si Ring Resonator

Laser &Photonics Reviews, EarlyView.
This work first demonstrates a single‐crystalline VO2–Si hybrid ring resonator. The epitaxial lift‐off process enables high‐quality VO2 integration on the dissimilar Si photonic platform. The high‐quality VO2 film exhibits exceptional nonlinear resonance modulation and a steep optical transition across the metal‐insulator transition. ABSTRACT The metal‐

A Perspective of Multi‐Reflecting TOF MS

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Time‐of‐flight mass spectrometry (TOF MS) excels in rapid and high‐sensitivity analysis, making it a cornerstone of analytical chemistry. But as sample complexity explodes in omics studies, so does the need for higher resolving power to ensure accurate results.

Existence of Solutions of Semilinear Wave Equations With Time‐Dependent Propagation Speed and Time Derivative Nonlinearity

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Consider wave equations with time derivative nonlinearity and time‐dependent propagation speed which are generalized versions of the wave equations in the Friedmann–Lemaître–Robertson–Walker (FLRW) spacetime, the de Sitter spacetime and the anti‐de Sitter space time.
