The preparation and electrical properties of high-temperature superconductor nanowire arrays are reported for the first time. YBa2Cu3O(7-delta) nanowires with widths as small as 10 nm (much smaller than the magnetic penetration depth) and lengths up to 200 microm are studied by four-point electrical measurements. All nanowires exhibit a superconducting transition above liquid nitrogen temperatu...
خTo reduce the construction costs of stilling basins of hydraulic jump type is sometimes, novel geometries are sometimes used to adopt the basin to the upstream and downstream sections without any transition structures. Otherwise, any changes in the geometry of the basin would cause changes in the conditions and characteristics of the hydraulic jump. In this study, the effects of variation in b...

The expressive power of neural networks is important for understanding deep learning. Most existing works consider this problem from the view of the depth of a network. In this paper, we study how width affects the expressiveness of neural networks. Classical results state that depth-bounded (e.g. depth-2) networks with suitable activation functions are universal approximators. We show a univer...
Silica is the most abundant oxide component in the Earth mantle by weight, and stishovite, the rutile-structured (P4(2)/mnm) high-pressure phase with silica in six coordination by oxygen, is one of the main constituents of the basaltic layer of subducting slabs. It may also be present as a free phase in the lower mantle and at the core-mantle boundary. Pure stishovite undergoes a displacive pha...
Implications of Venus Evolution Based on Ribbon Tessera Terrain Relations within Five Large Regional
Introduction. Venus' ribbon tessera terrain [1,2] (rtt) records ancient environmental conditions significantly different than contemporary Venus [3,4], and geologic relations are consistent with rtt representing the oldest locally exposed unit across Venus [5], although individual tracts of rrt may have formed at differnet times [6]. We have constructed a global geologic map of rtt exposures an...
Mapping the Moho depth and ocean-continent transition in the South China Sea using gravity inversion
One of the features unconventional $s_\pm$ state in iron-based superconductors is possibility to transform $s_{++}$ with increase nonmagnetic disorder. Detection such a transition would prove existence state. Here we study temperature dependence London magnetic penetration depth within two-band model for and superconductors. By solving Eliashberg equations accounting spin-fluctuation mediated p...
