Hardware implementation of reconfigurable and nonvolatile photoresponsivity is essential for advancing in-sensor computing for machine vision applications. However, existing reconfigurable photoresponsivity essentially depends on the photovoltaic effect of p-n junctions, which photoelectric efficiency is constrained by Shockley-Queisser limit and hinders the achievement of high-performance nonvolatile photoresponsivity. Here, we employ bulk photovoltaic effect of rhombohedral (3R) stacked/interlayer sliding tungsten disulfide (WS) to surpass this limit and realize highly reconfigurable, nonvolatile photoresponsivity with a retinomorphic photovoltaic device.

However, there is a rising incidence in CRC among individuals under 50 years of age, termed early-onset colorectal cancer (EOCRC). EOCRC patients are more advanced stage at diagnosis and may suffer more psychosocial, emotional and financial distress.

This study explores the thermoelectric potential of exfoliated penta-palladium-phosphorus-sulfur (PdPS) atomic layers, an air-stable 2D semiconductor with a puckered pentagonal low-symmetry structure, grown via chemical vapor transport (CVT). Thickness-dependent in-plane electrical conductivity (σ) and thermoelectric power factor (PF) of PdPS are investigated from 20-380 K, showing an increase in σ with thickness (11, 13, and 88-layer).

- - The study investigates the risk of hepatocellular carcinoma (HCC) in individuals with metabolic dysfunction-associated steatotic liver disease (MASLD) and a low fibrosis-4 index (FIB-4), which is used to assess liver health.
- - Out of 613 participants diagnosed with MASLD-related HCC, 13% had a low FIB-4, with 26% among those without cirrhosis, indicating potential missed cases for further evaluation.
- - The findings suggest that current guidelines may fail to identify over a quarter of MASLD-related HCC patients without cirrhosis who present a low FIB-4, highlighting a need for updated clinical pathways.
A multicenter multinational study to evaluate different aspects of the relationship between MS and pregnancy.

November 2024
Background: To investigate the pregnancy-related issues in females with multiple sclerosis (MS) from Turkiye, Egypt, Kuwait, and Iran.
Methods: 1692 pregnancies of 701 females with MS were evaluated in this retrospective multicenter, international project. Demographics, clinical features, pregnancy outcomes, relapses, effects of exposure to disease-modifying drugs on pregnancy and fetus, and worries about pregnancy decisions were investigated.
