Machine Learning‐Assisted Design and Performance Prediction of a Compact Dual‐Band Polarization‐Insensitive THz Metamaterial Absorber for Skin‐Cancer‐Related Refractive‐Index Sensing

open access: yesAdvanced Electronic Materials, EarlyView.
A compact QASRR‐based THz metamaterial absorber enables polarization‐insensitive dual‐band absorption and skin‐cancer‐related refractive‐index sensing through measurable resonance shifts. Field, surface‐current, and circuit analyses clarify the dual‐resonance mechanism, while StackNet‐assisted prediction accurately estimates the simulated absorption ...

Effects of a period without mandatory physical training on maximum oxygen uptake and anthropometric parameters in naval cadets.

open access: yesPLoS ONE, 2021
The effects of a period without physical training on the civilian population are well established. However, no studies show the effects of a period without mandatory physical training on maximum oxygen uptake (VO2 max) and anthropometric parameters in ...

Streamlined V3.5+ Electrolyte Production by Leveraging Chemical and Catalytic Reductions

open access: yesAdvanced Energy Materials, EarlyView.
A tuned catalytic process for V3.5+ electrolyte production is shown to streamline the conventional chemical‐to‐catalytic sequence by extending catalysis into the rate‐determining reduction regime. This study shows that initiating catalysis in this regime shortens the overall production time by 67% based on rigorous thermodynamic and kinetic analysis of

Comprehensive exploration of unexplained dyspnoea in subjects with normal ejection fraction and low natriuretic peptides

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 879-887, April 2025.
Abstract Background Unexplained exertional dyspnoea without significant elevation of natriuretic peptides is common. One of the causes might be early heart failure with preserved ejection fraction (HFpEF). Aims This study aimed to characterize patients with exertional dyspnoea and normal/near‐to‐normal N‐terminal pro‐brain natriuretic peptide (NT ...

Considerations for drug trials in hypertrophic cardiomyopathy

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1095-1112, April 2025.
Abstract Hypertrophic cardiomyopathy (HCM) is a heterogeneous condition with potentially serious manifestations. Management has traditionally comprised therapies to palliate symptoms and implantable cardioverter‐defibrillators to prevent sudden cardiac death. The need for disease‐modifying therapies has been recognized for decades.
