Long-Term Monitoring for Track Slab in High-Speed Rail via Vision Sensing
IEEE Access, 2020 Track slab deformation has become a challenging issue in high-speed rail (HSR) operation in recent years. This article proposed a novel approach for track slab deformation monitoring based on computer vision techniques.

The Failure of Monte Carlo Radiative Transfer at Medium to High Optical Depths [PDF]
, 2018 Computer simulations of photon transport through an absorbing and/or scattering medium form an important research tool in astrophysics. Nearly all software codes performing such simulations for three-dimensional geometries employ the Monte Carlo ...

Noise and Vibration of Resiliently Supported Track Slabs [PDF]
The Journal of the Acoustical Society of America, 1973 In this paper the dynamic response, vibration isolation, and sound radiation of a resiliently supported track slab are analyzed. An analytical model is investigated which views railroad rails as beams fastened elastically to a slab which is resiliently mounted to a substructure. The slab is assumed to be a plate of finite width and infinite length. The

Peptide Sequencing With Single Acid Resolution Using a Sub‐Nanometer Diameter Pore
Advanced Functional Materials, EarlyView.To sequence a single molecule of Aβ1−42–sodium dodecyl sulfate (SDS), the aggregate is forced through a sub‐nanopore 0.4 nm in diameter spanning a 4.0 nm thick membrane. The figure is a visual molecular dynamics (VMD) snapshot depicting the translocation of Aβ1−42–SDS through the pore; only the peptide, the SDS, the Na+ (yellow/green) and Cl− (cyan ...

Latitudinal dependence of wind-induced near-inertial energy [PDF]
, 2015 Mid-latitude storms, accounting for the majority of wind energy input to near-inertial motions in the ocean, are known to shift their track significantly from one year to another.

Advanced Functional Materials, EarlyView.Operando hard X‐ray absorption spectroscopy is applied to track the dynamic and interactive metal oxidation changes in iron group bimetallic hydroxides under different chemical and electrochemical conditions. It shows that Co and Fe oxidation are relatively equal and synchronized in CoFeOxHy.

Impermeable membranes for slab-track settlement mitigation [PDF]
Environmental Geotechnics, 2018 A series of numerical simulations is used to explore the effect of the geometrical disposition of impermeable membranes in the overall performance of slab-track railway earthworks, with particular reference to the generation of settlement during several years of exposure to the atmosphere and the admissibility of these post-construction deformations ...

Contact Lens with Moiré Patterns for High‐Precision Eye Tracking
Advanced Functional Materials, EarlyView.This work presents a passive contact lens for high‐precision eye tracking, integrating a microscopic moiré grating label. The parallax‐induced shift of macroscopic moiré patterns enables angle measurement with 0.28° precision using a standard camera under ambient light.
