The retinotectofugal system is the main visual pathway projecting upon the telencephalon in birds and many other nonmammalian vertebrates. The ascending tectal projection arises exclusively from cells located in layer 13 of the optic tectum and is directed bilaterally toward the thalamic nucleus rotundus. Although previous studies provided evidence that different types of tectal layer 13 cells ...

Thin films of topological insulators are often capped with an insulating layer since topological insulators are known to be fragile to degradation. However, capping can hinder the observation of novel transport properties of the surface states. To understand the influence of capping on the surface states, it is crucial to understand the crystal structure and the atomic arrangement at the interf...

The crystal structure of the synaptic SNARE complex reveals a parallel four-helix coiled-coil arrangement; buried in the hydrophobic core of the complex is an unusual ionic layer composed of three glutamines and one arginine, each provided by a separate alpha-helix. The presence of glutamine or arginine residues in this position is highly conserved across the t- and v-SNARE families, and it was...

Two dimensional nanostructures of group IV elements have attracted a great deal of attention because of their fundamental and technological applications. A graphene-like single layer of tin atoms, commonly called stanene, has recently been predicted to behave like a quantum spin Hall insulator. Here we report the atomic structure, stability and electron transport properties of stanene stabilize...

Cone calorimeter and controlled atmosphere cone experiments were conducted on various samples. The intent of the tests was to examine behavior uniform composite samples in a range thicknesses, irradiances, oxygen concentrations. Single, layers acrylonitrile butadiene styrene (ABS) compared mix, comprising ABS with surface layer cardboard secondary polyethylene bubble wrap (intended represent po...

Ge1?xSnx film with Sn content (at%) as high 13% was grown on Si (100) substrate Ge buffer layer by magnetron sputtering epitaxy. According to the analysis of HRXRD and Raman spectrum, quality crystal strongly dependent growth temperature. Among them, GeSn (400) diffraction peak at 240 °C lowest, which is consistent result. transmission electron microscope image, some dislocations appeared inter...

Natural composites are one of the smart materials that have opportunity to replace use synthetic composites. and metal materials. Layered structural provide nearly uniform properties on all sides. The purpose this study was determine mechanical tensile, compressive impact behavior bamboo fiber polymer with a layered structure. This research method is experimental where specimens made in 2 quasi...

Abstract Additively manufactured parts are characterized by a peculiar microstructure, originated the distinctive layer-by-layer process. In case of additive technology based on localized melting metallic feedstock, as laser-based powder bed fusion (LPBF), resulting microstructure has hierarchical arrangement, consisting macro- and microscopical features affecting final properties. Commonly, se...
