Heat Stress Promotes Fibroblast‐Derived WNT5A Secretion Through m6A Modification to Activate Melanogenesis

Advanced Science, EarlyView.
Heat stress promotes WNT5A secretion from fibroblasts via METTL3/YTHDC1‐dependent m6A methylation. Subsequently, WNT5A binds to FZD10 on melanocytes, activating β‐catenin‐driven melanogenesis. ABSTRACT As the impact of global warming continues to intensify, the effects of heat stress on the skin are becoming increasingly evident.

Implementation and Evaluation of the Synchronization Protocol Immediate Priority Ceiling in PREEMPT-RT Linux

Journal of Software, 2012
In general purpose operating systems, such as the mainline Linux, priority inversions occur frequently and are not considered harmful. They are not avoided or limited as in real-time systems. In the current version of the kernel PREEMPT-RT Linux, the protocol used for  priority inversion control is the Priority Inheritance.

From Charge‐Transfer Adducts to (Tri)Halide‐Templated Supramolecular Cages: Covalent vs Ionic Products in the Reactions of Pyridin‐4‐ylthio‐Substituted Tetrathiafulvalene With Dihalogens and Interhalogens

Chemistry – A European Journal, EarlyView.
The reactions between tetra(pyridin‐4‐ylthio)tetrathiafulvalene and Br2/I2/ICl/IBr led to a variety of products, including a rare example of neutral 1:4 CT adduct and ionic products showing supramolecular cage motifs at (tri)halide templates. The nature of the reaction products was elucidated based on XRD analysis, Raman spectroscopy and QTAIM, NCI ...

A Voxel‐Wise T2 Distribution Framework for Lesion Severity Stratification and Treatment‐Response Assessment in Stroke: Insights Into Suberoylanilide Hydroxamic Acid‐Induced Neuroprotection

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate lesion severity distribution in ischaemic brain lesions in spontaneously hypertensive rats (SHR) subjected to 90‐min transient middle cerebral artery occlusion (tMCAO), and to determine whether epigenetically based neuroprotection modifies lesion severity profiles using a voxel‐wise T2 distribution framework.

Predicting Runtime in Spark‐Like Systems With Allocation‐Aware Deterministic Models

Software: Practice and Experience, EarlyView.
ABSTRACT Objectives Apache Spark is widely used for distributed data processing, but accurately predicting application execution time remains challenging because performance depends on application structure, resource configuration, and executor‐allocation behavior.
