Abstract Topological photonic crystals, which offer topologically protected and back-scattering-immune transport channels, have recently gained significant attention for both scientific and practical reasons.Although most current studies focus on dielectric materials with weak dispersions, this study focuses on topological phases in dispersive mate
BackgroundThoracoabdominal acute aortic syndrome is associated with high morbidity and mortality.We aim to scrutinize our evolving strategies for acute aortic syndrome (AAS) management using minimally invasive and adaptive surgical techniques over two decades.MethodsThis is a longitudinal observational study at our tertiary vascular centre from 200
Multi-speed transmission can greatly improve the power and economic performance of electric vehicles (EVs) compared with single-speed transmission.Gear ratio is the key design parameter of multi-speed transmission.Optimizing gear ratios can further improve vehicle performance.Most of the existing optimization methods of gear ratios take the power a
PurposeTo explore the clinical phenotype and genetic defects of Bed Accessories families with congenital aniridia.MethodsFour Chinese families with aniridia were enrolled in this study.The detailed ocular presentations of the patients were recorded.Whole exome sequencing (BGI MGIEasy V4 chip) was used to detect the gene mutation.Sanger sequencing w
The studies were conducted on the natural waters of Georgia: Gortubani and Naminauri (Adigeni region), Danisparauli, Dandalo and Makhinjauri (Adjara region) which exhibit medicinal properties.The following water indicators were determined: titratable acidity, electrical conductivity, hardness, the content of solids, sulfates, chlorides, hydrocarbon
