BackgroundMalassezia restricta is a lipid-dependent yeast species that commonly colonizes human and warm-blooded animal skin as an opportunistic pathogen. Although strongly associated with dermatological conditions like seborrheic dermatitis, central nervous system (CNS) infections caused by Malasse...

This Special Issue showcases cutting-edge advances in the design, synthesis, and multifaceted applications of Metal–Organic Framework (MOF)-based micro/nanoscale materials [...]

Abstract We present the first P wave radial anisotropy tomography of the crust and upper mantle beneath the North China Craton (NCC), determined using a large number of high‐quality arrival‐time data of local earthquakes and teleseismic events. Our results show a prominent high‐velocity (high‐V) ano...

In this paper, the Thaumantis diores Doubleday, 1845-complex, including T. diores Doubleday, 1845 and T. hainana (Crowley, 1900), is studied, and a new subspecies, T. hainana libodiores Lang & Wang, ssp. nov., is described from Guizhou province, S.W. China.

The traditional method to rotate an image of light is by using a Dove prism, even though it is unreliable, owing to the mechanical adjustment when a tunable image rotation is required. Here, we propose a flexible and nonmechanical scheme to rotate an optical image by an arbitrary angle with optical...
