Dual-Kinetic Relaxation Spectroscopy for Discrimination of Volatile Organic Mixtures via Finite-Size Surface Gratings

Abstract Discrimination of chemically similar volatile organic compounds (VOCs) in gas mixtures remains a challenge for traditional optical refractive index sensors. In this work, we used a surface holographic grating relaxation technique to monitor the transport kinetics of VOCs...

The Infinite Volume Limit of the Hopfield Neural Networks in the Replica-Symmetric Regime

Abstract Despite extensive research over the past five decades, a rigorous determination of the infinite volume limit of the free energy of the Hopfield model with an extensive number of patterns has remained an outstanding open problem as standard methods from spin glass theory...

Alzheimer's Co‐Pathology Burden on Basal Forebrain Atrophy and Cognitive Impairment in Dementia with Lewy Bodies: A Cross‐Sectional Pilot Study

OBJECTIVE: Dementia with Lewy Bodies (DLB) is the second most common neurodegenerative dementia after Alzheimer's disease (AD), with significant pathological overlap between the two conditions. However, the impact of Alzheimer's co-pathology on basal forebrain (BF) atrophy and it...

Eco‐Designed Transparent Bacterial Cellulose Composites for Next‐Generation Opto‐Electronics

ABSTRACT Sustainable, bio‐based alternatives to petrochemical substrates are essential for the fabrication of next‐generation optoelectronic devices. However, very few natural materials offer simultaneously high transparency, mechanical robustness, and functional versatility. Bac...

Dynamic topological exciton-polaritons enabling ultrafast logic operations

Topological active materials have emerged as a powerful paradigm bridging the discovery of exotic topological phases of matter with the development of functional topological devices. The recent extension of these material systems into dynamic regime, where topological properties...

Sensing‐Integrated Patient‐Derived Tumorspheres Predict Chemotherapeutic Efficacy via Local Extracellular pH Dynamics

ABSTRACT Pancreatic ductal adenocarcinoma (PDAC) is among the deadliest malignancies, due to late diagnosis, poor therapeutic response, and high inter‐ and intra‐patient heterogeneity. Metabolic alterations, particularly extracellular acidification, critically impair drug respons...
