Benchmarking Hybrid CNN‐Transformer Versus Pure Transformer Architectures for Accelerated Hyperpolarized 129Xe MRI Reconstruction

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Hyperpolarized 129Xe MRI faces technical challenges including low signal‐to‐noise ratio and breath‐hold constraints. Current literature focuses on proprietary deep learning methods or image‐domain enhancements. Purpose To present a comprehensive evaluation of transformer and hybrid CNN‐transformer architectures integrating dual ...

Role of COL1A1 and CD44 in Modulating JAK1/STAT3‐Mediated Autophagy for Spinal Cord Injury Recovery

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Spinal cord injury (SCI) is a severe trauma to the central nervous system that often leads to motor and sensory dysfunction in patients, severely affecting their quality of life. Autophagy plays a role in the pathological process of SCI, but the specific mechanism of autophagy in this case is unknown.

Construction of a Non‐Invasive Predictive Model Based on PIVKA‐II Combined With MRI Imaging Features for Evaluating Microvascular Invasion in Hepatocellular Carcinoma

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study developed a non‐invasive model using PIVKA‐II and MRI features to predict microvascular invasion in hepatocellular carcinoma, providing a reliable tool for early risk assessment and personalized treatment planning. The study included 98 patients with pathologically confirmed HCC (Child‐Pugh A, BCLC stage A), comprising 43 MVI ...

Quantifying Soft‐Surgery in Cochlear Implantation: Multimodal Data From 30 International Specialists

open access: yesThe Laryngoscope, EarlyView.
Objective data from 30 specialist cochlear implant surgeons showed that surgical handling strongly influences intracochlear mechanical stress during implantation. Surgeons with fewer than 50 lifetime insertions performed significantly worse than more experienced colleagues, while self‐assessment did not reflect objective performance in any group ...

Corrosion Performance of Prepainted Galvanized Steel After 8‐Year Outdoor Exposure Upon the Distance to the Seashore in Temperate Environment

open access: yesMaterials and Corrosion, EarlyView.
The corrosion performance of line‐produced prepainted galvanized steel products was investigated upon the distance to the seashore in temperate environment over 8‐year exposure. The rate of underpaint corrosion from cut‐edge was estimated and depended on the agressiveness of the site and the angle of exposure.

Structure‐Aware Machine Learning for Polymers: A Hierarchical Graph Network for Predicting Properties From Statistical Ensembles

open access: yesMacromolecular Rapid Communications, EarlyView.
This work presents a structure‐aware graph convolutional network that models polymers as statistical ensembles to predict macroscopic properties. By combining topologically realistic graphs generated via kinetic Monte Carlo simulations with explicit molar mass distributions, the framework achieves high accuracy in classifying architectures and ...

The oxygen‐sensing FixLJ represses nitrogen fixation in Rhodopseudomonas palustris in response to oxygen

open access: yesmLife, EarlyView.
Abstract Biological nitrogen fixation in symbiotic diazotrophs is subject to oxygen regulation by an oxygen‐sensing FixLJ two‐component system under micro‐oxic conditions. However, it remains unclear whether this mechanism is conserved in free‐living diazotrophs.

Proteome Analysis of Corynebacterium diphtheriae–Macrophage Interaction

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Contact of Corynebacterium diphtheriae with macrophages induces adaptations on both bacterial and cellular sides. The study presented here was aiming to shed light on the simultaneous intracellular adaptation of the bacteria and changes in the proteome of the phagocytes in response to the internalization of C. diphtheriae.

Evaluation of a High‐Performance Monopropellant Formed of Microencapsulated Hydrocarbon Fuels in Combination With Gelled Hydrogen Peroxide in a Strand Burner Setup

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
A high‐performance premixed monopropellant is prepared from hydrocarbon‐filled microcapsules and hydrogen peroxide. This propellant is burned in a strand burner, and the effect of different parameters on the burn rate is evaluated. ABSTRACT A dispersion of hydrocarbon‐fuel‐filled microcapsules in gelled hydrogen peroxide can form a premixed ...
