Advances in Triboelectric Nanogenerators With Rotating Structure
Carbon Energy, EarlyView.The rotating TENG has been widely studied for its superiorities of simple structure, high efficiency, and stable output. This review introduced the four different principles of rotating TENG and offered a thorough summary for performance and application research through three‐level classification. Importantly, the current existing problems, challenges,

Railways; railways - selected characteristics
, 1973 Contained within the 4th Edition (1974) of the Atlas of Canada is a set of two maps accompanied by graphics. The first map shows the extension of the railway network. Gradual extensions are denoted for the following periods: 1836 to 1852, 1853 to 1880, 1881 to 1905, 1906 to 1918, 1919 to 1935, 1936 to 1952 and 1953 to 1971.

Investigating the Cytoskeleton of DRGs Using Cryo‐Electron Microscopy and Deep Learning
Cytoskeleton, EarlyView.ABSTRACT We describe a method for determining the ultrastructural organization of axons and varicosities of cultured dorsal root ganglion (DRG) neurons using cryogenic electron microscopy (cryo‐EM). Cryo‐EM reveals the dimensions, proximity, and overall organization of biological specimens in a near‐native state, avoiding artifacts of fixation and ...

Deep Underground Science and Engineering, EarlyView.The permeability variation of rocks during complete stress–strain processes was investigated. A mathematical model describing the influence of rock damage on permeability was constructed. The permeability–stress relationship between soft rock and hard rock was proposed.

Creep properties and constitutive model of diabase in deep water conveyance tunnels
Deep Underground Science and Engineering, EarlyView.The axial and lateral creep characteristics of diabase were analyzed based on compression creep tests. The nonlinear viscoelastic‐plastic model capable of describing the whole creep process was established based on the fractional derivative and damage theories.

Complex delay dynamics on railway networks: from universal laws to realistic modelling
, 2018 Railways are a key infrastructure for any modern country. The reliability and resilience of this peculiar transportation system may be challenged by different shocks such as disruptions, strikes and adverse weather conditions. These events compromise the

Deep Underground Science and Engineering, EarlyView.This paper investigates the high‐pressure water jet‐pick combined rock‐breaking mode (HPC), which employs high‐pressure water jets to precut grooves on both sides of the picks. The rock‐breaking patterns and performance of the HPC method are obtained, and the auxiliary rock‐breaking mechanism of water jet grooving is revealed.

The Maraca: a tool for minimizing resource conflicts in a non-periodic railway timetable [PDF]
, 2011 While mathematical optimization and operations research receive growing attention in the railway sector, computerized timetabling tools that actually make significant use of optimization remain relatively rare. SICS has developed a prototype tool for non-

Deep Underground Science and Engineering, EarlyView.Abstract As tunnel construction advances in lengths and depths, the construction of tunnels in high geothermal environments has become increasingly common, raising significant fire risks. In this study, a 1:20 scale model tunnel test platform was constructed to investigate the effects of a high geothermal environment on fire behavior in tunnels during ...
