The Noise-Reduction Characteristics of Microstructure of Dragonfly Wing Leading Vein
Dragonfly wings have many excellent functions, such as superhydrophobic, fatigue resistance, anti-reflection, etc. However, there are few reports on the low noise flight of dragonfly wings.

Cuttlebone‐inspired architected metamaterials introduce controlled structural disorder to simultaneously enhance strength, energy absorption, and compressive stability. Tunable disorder suppresses shear anisotropy, outperforms periodic lattices, and establishes discrete randomness as a robust route to high‐performance lightweight mechanical ...

Epidermolysis bullosa acquisita: current diagnosis and therapy
Epidermolysis bullosa acquisita (EBA) is an acquired, autoimmune subepidermal blistering disease with an approximate prevalence of 0,2/million people. The hallmark of EBA is the presence of autoantibodies (mainly IgG class) to anchoring fibril collagen ...

The precipitate evolution in friction stir welding of 2195-O Al–Li alloy
The precipitate evolution of friction stir welding (FSW) 2195-O Al–Li alloy was analyzed by back scattered electron (BSE), X-ray diffraction (XRD), differential scanning calorimetry (DSC) and transmission electron microscopy (TEM).

Serrated adenoma of the duodenum [PDF]
The duodenum is the most common site for extracolonic adenomas in patients with familial adenomatous polyposis (FAP). These adenomas are usually tubular, villous, or tubulovillous. This report describes a patient with FAP who had a duodenal adenoma with a different histology—it had the microscopic attributes of a serrated adenoma—tumours that are ...

Strong‐yet‐ductile precipitation‐hardening alloys require novel microstructural complexity of precipitates in particularly at cryogenic condition, to constantly impart strain hardening of hard‐and‐brittle precipitates. The present work creates innovative structurally complex precipitates assembled with dispersed nanocores and a chemical‐heterogeneity ...

A Hadfield steel has been investigated to clarify the serrated flow and to explore the failure behavior at room temperature. The tensile experiments were performed under extensometer-measured strain control, rather than under conventional cross-head ...

ABSTRACT The Homologous Recombination Factor With OB‐Fold (HROB) plays a role in homologous recombination and DNA replication, where it enhances the MCM8‐MCM9 helicase complex activity. Recent findings link biallelic germline HROB variants to primary gonadal insufficiency (hypergonadotropic hypogonadism), a phenotype also associated with MCM8/MCM9 ...
