All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

Advanced Functional Materials, EarlyView.
An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

Unraveling ovarian histology: The key morphological aspects that spur the development of the Fossa ovarii in equine

The Anatomical Record, EarlyView.
Abstract The equine ovary exhibits unique structural and developmental features that distinguish it from those of other domestic species, including the presence of an ovulation fossa and an inversion of cortical and medullary layers. This study aimed to investigate the morphostructural development of the equine fetal ovary, with particular emphasis on ...

Metrnβ drives sepsis immunosuppression via macrophage reprogramming: A novel prognostic biomarker and therapeutic target

Interdisciplinary Medicine, EarlyView.
Metrnβ serves as a novel prognostic biomarker for sepsis and that targeted blockade of the Metrnβ‐c‐Kit axis represents a promising therapeutic strategy for sepsis. Abstract Sepsis is a heterogeneous syndrome critically driven by immunosuppression, yet lacking personalized prognostic markers and therapeutic targets. Here, we provide evidence to support

Single‐Cell Profiling Identifies CLEC5A+ Macrophages as Key Drivers of Thoracic Aortic Aneurysm Via CCL5‐Mediated M1 Polarization

Journal of Clinical Laboratory Analysis, EarlyView.
Thoracic aortic aneurysm (TAA) is a life‐threatening cardiovascular disease with limited therapeutic options. Through single‐cell RNA sequencing of aortic tissues from healthy individuals and TAA patients (105,541 cells), we identified CLEC5A+macrophages as the predominant pathogenic cell population exhibiting the highest M1 polarization score.
