Sensitivity and Hamming Graphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT For any m ≥ 3 $m\ge 3$ we show that the Hamming graph H ( n , m ) $H(n,m)$ admits an imbalanced partition into m $m$ sets, each inducing a subgraph of low maximum degree. This improves previous results by Tandya and by Potechin and Tsang, and disproves the Strong m $m$‐ary Sensitivity Conjecture of Asensio, García‐Marco, and Knauer.

Deciphering nodal burden in thyroid carcinoma: A dedicated survey of age, lymph node ratio, log odds of positive nodes, and preoperative prediction models

open access: yesJournal of Intelligent Medicine, EarlyView.
Abstract Evidence regarding the prognosis of thyroid carcinoma is heterogeneous, ranging from age effects and nodal burden metrics, such as lymph node ratio (LNR) and log odds of positive nodes (LODDS), to preoperative imaging models comprising ultrasound, CEUS, and radiomics.

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

open access: yesInternational 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.

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

open access: yesJournal 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 ...

Recent Advances in Photonic Bound States in the Continuum: From Fundamentals to Engineering and Implementation

open access: yesLaser &Photonics Reviews, EarlyView.
This review summarizes recent progress in meta‐photonics with a focus on bound states in the continuum (BICs) as a powerful platform for light confinement and control. It covers fundamental concepts, design strategies across optical regimes, symmetry breaking for practical quasi‐BICs, tunable and AI‐assisted BIC devices, and emerging applications in ...
