The effect of prenatal sensory stimulation on the parvalbumin neurons in entopallium and visual Wulst

Conserved genetic mechanisms participate in developing brain asymmetries in vertebrates, but the effect of prenatal sensory stimulation on lateralised neural circuits is less understood. In birds, lateralisation emerges from the interaction of genetic factors and prenatal experience. Light exposure during a sensitive stage of embryonic development asymmetrically stimulates the two eyes, causing lateralised visual functions. However, nothing is known about its effects on the cell composit...

A Self-Supervised Approach to Pixel-Level Change Detection in Bi-Temporal RS Images

Deep-learning techniques have achieved great success in remote-sensing image change detection. Most of them are supervised techniques, which usually require large amounts of training data and are limited to a particular application. Self-supervised methods solve these problems and are widely used in unsupervised binary change detection tasks. However, the existing self-supervised methods in change detection are suboptimal for pixel-wise change detection tasks. In this work, a pixel-wise contr...

Experimental Evaluation of Rolling Contact Fatigue in Railroad Wheels

Surface damage in railroad wheels is a very complex phenomenon and the contact fatigue plays a fundamental role in the damage process. In the case of railroad wheels the actual fracture process is quite different from the conventional idea of fracture in a load bearing structural component. The cracks that are generated by contact fatigue are not the source of actual wheels cracking but lead to the damaging phenomenon called shelling which implies separation of chunks of material from the sur...
