Dual PN Source/Drain Reconfigurable FET for Fast and Low-Voltage Reprogrammable Logic
IEEE Access, 2020 Schottky junction reconfigurable FETs suffer from limited output currents to drive the following stages, jeopardizing their viability for high-end applications. This drawback becomes dramatic at low voltages.

Chasing Charge Carriers: Diffusion Dynamics in Mixed‐n Quasi‐2D Colloidal MAPbBr3 Perovskites
Advanced Functional Materials, Volume 35, Issue 34, August 22, 2025.Metal halide perovskites are noted for their tunable optical properties. Colloidal synthesis allows the formation of differently shaped perovskite nanocrystals with varying optical and carrier transport behavior. Three MAPbBr3 morphologies are characterized: nanoplatelets, nanosheets, and nanostripes.

Expert Systems, Volume 42, Issue 7, July 2025.ABSTRACT Receiver operating characteristic curves are commonly used to evaluate the performance of machine learning ensemble classification models that combine multiple classifiers through a voting procedure. Although these models have many parameters, standard ROC analyses typically vary only the voting threshold, limiting their potential for ...

Advanced Healthcare Materials, Volume 14, Issue 10, April 15, 2025.Helicobacter pylori gastric infection is widespread and recurrency is common, fuelled by bacterial resistance to antibiotics. Therefore, specific and noninducing resistance alternative treatments are an urgent need. Taking advantage of this gastric pathogen auxotrophy for cholesterol, a “trojan horse” strategy for H.

AGING MEDICINE, Volume 8, Issue 2, Page 145-155, April 2025.ABSTRACT Purpose Premature cellular senescence is a pivotal process in aging and age‐related diseases, triggered by various stressors. However, this is not a homogeneous phenotype, but a heterogeneous cellular state composed of multiple senescence programs with different compositions. Therefore, understanding the complex dynamics of senescence programs
