We have used the TOPAS simulation framework to model direct conversion of 511 keV gamma rays electrons in a micro-channel plate (MCP) constructed from thin laminae heavy-metal-loaded dielectric such as lead-glass, patterned with micro-channels (LMCP). The serve converter ray primary electron within depth channel-forming surface that penetrates channel (‘surface conversion’). channels are coated...

In this paper, a new composite floor system using cold-formed thin-walled C steel channel embedment and foam concrete slab is developed. This type of features lightweight, high fire-resistant, anti-corrosion features, can be used for multi-story buildings, providing promising alternative the construction market. Two four-point bending tests were carried out to investigate flexural capacity fail...

For the purpose of increasing capacity an Angang Strip Production (ASP) continuous caster and surface quality a medium-thin slab with mold sections 150 × (1020–1540) mm2, present work investigated influences submerged entry nozzle (SEN) structure main operating parameters on flow characteristic temperature distribution in by physical numerical simulations. The results showed that typical “doubl...

The generation of a 33.7 W radially polarized output is demonstrated by way double-pass amplification in Ho:YAG thin-slab crystal. amplifier system was seeded with the beam from continuous-wave 13.2 W, 2.1 µm rod laser, which exploited gain medium bifocusing and ring-shaped pump spot to promote preferential lasing on Laguerre–Gaussian mode. By compensating for both thermally induced stress bire...

[1] Although mantle slabs ultimately drive plate motions, the mechanism by which they do so remains unclear. A detached slab descending through the mantle will excite mantle flow that exerts shear tractions on the base of the surface plates. This ‘‘slab suction’’ force drives subducting and overriding plates symmetrically toward subduction zones. Alternatively, cold, strong slabs may effectivel...

Electrostatic charges near the interface between topological (TI) and ordinary (OI) insulators induce magnetic fields in medium that can be described through so-called method of image dyons (electric charge - monopole pairs), magnetoelectric extension classical electrostatics. Here, we provide expressions for ensuing potentials a system comprised by two planar-parallel OI-TI interfaces conformi...

At present, reducing subgrade settlement of soft soil foundation is a key problem in high-speed railway construction. Pile-slab structure is a widely-utilized form of foundation structure to reduce the subgrade settlement in China. In order to save the engineering cost for high-speed railway construction in developing countries, the author developed a pile-slab structure and named it as the new...

We present new tomographic models of the Nazca slab under South America from 6°S to 32°S, and from 95 km to lower mantle (895 km) depths. By combining data from 14 separate networks in the central Andes, we use finite-frequency teleseismic P-wave tomography to image the Nazca slab from the upper mantle into the mantle transition zone (MTZ) and the uppermost lower mantle on a regional scale. Our...

We investigate the influence of slab thickness on the electronic structure of the Si(1 0 0)- p([Formula: see text]) surface in density functional theory (DFT) calculations, considering both density of states and band structure. Our calculations, with slab thicknesses of up to 78 atomic layers, reveal that the slab thickness profoundly affects the surface band structure, particularly the danglin...
