Anisotropic Cellular Forces Drive Hexagonal‐to‐Tetragonal Tiling Transitions in the Drosophila Eye

Development, Growth & Differentiation
ABSTRACT Tile patterns are fundamental organizational principles of multicellular epithelial tissues. The Drosophila compound eye provides a striking example, in which ommatidia are arranged in a highly regular hexagonal lattice, while tetragonal patterns emerge in specific ...

Deep learning‐based prediction of cervical lymph node metastasis and genetic alterations from whole‐slide images of thyroid cancer frozen sections

Interdisciplinary Medicine, EarlyView.
Deep learning models accurately predict cervical lymph node metastasis and key genetic mutations (BRAF/TERT) directly from thyroid cancer frozen sections. This AI‐driven pipeline provides a rapid real‐time tool to guide intraoperative surgical decisions, helping to optimize surgical extent and prevent both over‐ and under‐treatment without the need for

Reliable labels, uncertain meaning: Classifications for medial meniscus posterior root tears lack consensus and arthroscopy‐anchored accuracy

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
ABSTRACT Purpose Multiple, nonharmonised classification systems exist for posterior medial meniscus root tears (PMMRT), yet their diagnostic accuracy and observer reliability remain unclear. This PRISMA‐2020 systematic review aimed to catalogue available PMMRT classifications and to summarise accuracy and reliability metrics.

Eliminating Conflict Misses for Tiled Codes

, 2008
Tiling is a powerful compiler technique for exploiting data locality in scientific codes. However, previous research has shown conflict misses occurring due to caches with limited associativity can significantly degrade the performance of tiled codes ...

Reducing Motion Artifact in High Resolution 7 T MRI Using the Magnetic Resonance Minimal Motion (“MR‐MinMo”) Head Stabilization Device

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate the effectiveness of the MR‐MinMo head stabilization device in mitigating motion artifacts during long‐duration, high‐resolution 7 T MRI scans, with and without retrospective motion correction Methods The MR‐MinMo was tested on seven pediatric and 12 adult healthy volunteers using 0.6 mm isotropic, 3D Multi‐Echo Gradient ...

Nonwoven rCF/PA6 Thermoplastic Composites: Hybrid Commingled Fibers vs. Powder Impregnation—Effects on Microstructure and Mechanical Properties

Polymer Composites, EarlyView.
Comparison of powder impregnation and hybrid commingled non‐wovens for PA6/rCF nonwoven composites. The two‐step powder route gives lower voids and higher properties, while the single‐step hybrid route is limited by precursor inhomogeneity and high void content.

"Passive Force Covering" (anti‑impulse meta‑tiles)

Passive Shock-Protective Surface (PSP) is a modular, power-free protective covering for floors, walls, and ceilings that reduces peak impact and blast loads by routing energy laterally and dissipating it within the material stack. The PSP tile combines: (1) a low-friction shear interface that lets the top sheet slip a controlled 1–3 mm; (2) an auxetic ...
