Chemically Driven Nano‐Elastic Heterogeneities Control Fragility in Volcanic Melts

open access: yesAdvanced Science, Volume 13, Issue 5, 27 January 2026.
The study elucidates how nanoscale structural heterogeneity governs the mechanical behavior of volcanic glasses across compositions from basalt to rhyolite. Using a physicochemical framework, correlation length (ξ) and microscopic free volume (Vc) are derived from vibrational and physical properties, revealing systematic trends with silica content that

Evaluation of Present and Future Relationships Between Daily Precipitation and Temperature in Eastern China

open access: yesInternational Journal of Climatology, Volume 46, Issue 1, January 2026.
We examined temperature–precipitation scaling across NE and SE China using observations, ERA5, and CMIP6 MME data. All datasets show a peak structure, with precipitation intensifying up to a peak temperature and declining thereafter. ERA5 overestimates scaling rates, approaching the CC rate, while MME underestimates them, especially in SE China. Across

Body Surface Mapping of Ventricular Repolarization Heterogeneity: An Ex-vivo Multiparameter Study

open access: yesFrontiers in Physiology, 2020
BackgroundIncreased heterogeneity of ventricular repolarization is associated with life-threatening arrhythmia and sudden cardiac death (SCD). T-wave analysis through body surface potential mapping (BSPM) is a promising tool for risk stratification, but ...

Extraction and Comprehensive Characterization of Starch From Ryegrass (Lolium multiflorum L.) Seeds as a Non‐Conventional Source

open access: yesStarch - Stärke, Volume 78, Issue 1, January 2026.
A native starch was extracted from ryegrass (Lolium multiflorum L.), yielding a high‐purity product with a significant starch content. The starch exhibited type A and V crystallinity, with a mean particle size (D50) ~7 nm, high swelling power, and low retrogradation tendency.

Malignant ventricular arrhythmias in patients with implantable cardioverter-defibrillators: electrical signals which are predictors of recurrence

open access: yesCorSalud, 2017
Introduction: There is a growing number of patients with implantable cardioverter-defibrillators. Recurrences are frequent and electrical shocks are the main factor affecting the quality of life. Objective: To identify the electrocardiographic predictors

ECG Markers of Positive Drug Challenge With Ajmaline in Patients With Brugada Syndrome

open access: yesAnnals of Noninvasive Electrocardiology, Volume 31, Issue 1, January 2026.
A prominent S‐wave in lead II on a nondiagnostic baseline ECG is a powerful predictor for unmasking Brugada syndrome during an ajmaline challenge. This subtle sign enhances patient selection for provocation testing and aids in risk stratification, particularly in familial screening.

Artificial Intelligence–Enhanced Electrocardiography for the Diagnosis of Heart Failure With Preserved Ejection Fraction: A Systematic Review and Meta‐Analysis

open access: yesCardiology Research and Practice, Volume 2026, Issue 1, 2026.
Background Accounting for approximately 50% of heart failure, heart failure with preserved ejection fraction (HFpEF) is becoming increasingly common as populations age and multimorbidity grows. Diagnosis remains challenging, requiring multimodal testing with echocardiography, biomarkers and sometimes invasive haemodynamics.
