This study aims to establish an imitation task of multi-finger haptics in the context of regular grasping and regrasping processes during activities of daily living. A video guided the 26 healthy, right-handed volunteers through the three phases of the task: (1) fixation of a hand holding a cuboid, (2) observation of the sensori-motor manipulation, (3) imitation of that motor action. fMRI recorded the task; graph analysis of the acquisitions revealed the associated functional cerebral connectivity patterns.

The accurate estimation of the temperature distribution of the GaN based power devices and optimization of the device structure is of great significance to possibly solve the self-heating problem, which hinders the further enhancement of the device performances. We present here the operando temperature measurement with high spatial resolution using Raman spectroscopy of AlGaN/GaN high electron mobility transistors (HEMTs) with different device structures and explore the optimization of the device thermal design accordingly. The lateral and depth temperature distributions of the single-finger HEMT were characterized.

MicroRNAs (miRNAs) are highly conserved endogenous non-coding RNAs that play a crucial role in fish immune response by regulating gene expression at the post-transcriptional level. In recent years, the viral diseases caused by infectious hematopoietic necrosis virus (IHNV) have caused significant economic losses in rainbow trout (Oncorhynchus mykiss) aquaculture, whereas the immune regulatory mechanisms of miRNAs involved in rainbow trout resistance to IHNV infection remains largely undefined. In this study, we analyzed the structural characteristics of Oncorhynchus mykiss tumor necrosis factor receptor-associated factor 3 (OmTRAF3) by bioinformatics software and explored the molecular mechanism of miR-203-3p in rainbow trout resistance to IHNV by regulating OmTRAF3 in vivo and in vitro.

HIV self-sampling and -testing (HIVSS/ST) reduces testing barriers and potentially reaches populations who may not test otherwise. In the Netherlands, at-home HIV tests became commercially available around 2016, but data on user experiences are limited. This study aimed to explore characteristics of users and their experiences with HIVSS/ST.
