Real‐Time Tire Tread Identification From Wheel Tracks Using YOLOv11 and Triplet Embedding

International Journal of Intelligent Systems, Volume 2026, Issue 1, 2026.
This paper presents a unified real‐time framework for tire tread identification that integrates tire‐mark detection and tread retrieval into a single end‐to‐end pipeline. Unlike existing studies that directly apply standard YOLO or metric‐learning models, the proposed system introduces three key innovations: (1) a YOLOv11‐based detector customized with

Controllable Liquid Metal Microparticles Production and Patterning by Miniaturized Filter‐Sieve Generators

Small Methods, Volume 9, Issue 11, November 24, 2025.
A miniaturized filter‐sieve generator is introduced as an innovative, compact platform for scalable production and patterning of liquid metal microparticles. By leveraging a simple electrochemical mechanism, the MFSG achieves high productivity, energy efficiency, and precise size control. Its versatility is demonstrated in LM droplet patterning and the

Insulin facilitates entry of calcium ions into human and murine erythrocytes via Piezo1: a newly identified mechanism with implications for type 2 diabetes

The FEBS Journal, Volume 292, Issue 20, Page 5457-5474, October 2025.
Despite being enucleated, mammalian red blood cells (RBCs) possess complex signaling mechanisms. Here, we show that insulin signals through the mechanosensitive channel Piezo1 to promote influx of calcium ions. This newly identified pathway is disrupted in a murine model of type 2 diabetes and may contribute to driving circulatory deficits in prevalent

Activation of Kir4.1 Channels by 2‐D08 Promotes Myelin Repair in Multiple Sclerosis

Advanced Science, Volume 12, Issue 34, September 11, 2025.
Multiple sclerosis causes myelin loss and neurological dysfunction. This study shows that 2‐D08, a small molecule targeting Kir4.1 channels, promotes OPCs differentiation via FYN tyrosine kinase phosphorylation and the FYN/MYRF pathway. It significantly improves myelin repair and motor deficits in EAE mice and marmosets, highlighting its potential as a

The Fashioning of the Humanist Governor at the Dawn of a New Political and Cultural Era: Francesco Barbaro as Podestà of Venetian Vicenza

Renaissance Studies, Volume 39, Issue 4, Page 473-492, September 2025.
Abstract The patrician Francesco Barbaro (1390–1454) is well known for having been both a first‐class humanist and a figurehead of the Venetian government in the new territories of the Stato da Terra. This article explores the pioneering use of humanist culture in the official praises he received during his political career, which helped shape a ...
