Seismic Damage and Track Irregularity Analysis of High-Speed Railway Track–Bridge Systems Under Near-Fault Earthquakes and CA Mortar Layer Void

Buildings
High-speed railway track–bridge systems (HSRTBSs) in near-fault high-seismicity regions face combined threats from pulse-type seismic excitations, vertical earthquake components and track defects, which may trigger structural damage and deterioration of ...

Amphoteric Cu‐Doping Leading to High Thermoelectric Performance in p‐Type Bismuth Antimony Telluride

Advanced Functional Materials, EarlyView.
This study shows that Cu plays two opposite roles in p‐type Bi0.5Sb1.5Te3 depending on the processing route. Under thermodynamic‐equilibrium bulk‐synthesis, Cu mainly occupies cation sites, increases hole concentration, preserves mobility, and slightly reduces lattice heat transport. The best‐performing composition among the investigated series reaches

Seismic responses of regular highway bridges under near-fault ground motions (COMPDYN 2017) [PDF]

, 2017
Ground motions recorded in near-fault areas have some specific characteristics that differ substantially from those recorded in far-fault regions. One of the main features of near-fault records is the pulse-like shape caused by forward-directivity effect.

Energetic Offset in Organic Solar Cells‐ Importance, Confusion and Outlook

Advanced Materials, EarlyView.
Energetic offsets in organic solar cells (OSCs) remain a subject of debate due to measurement‐ and lab‐dependent discrepancies. This Perspective clarifies the physical origins of these variations and identifies temperature‐dependent electro‐optical methods as a reliable approach to obtain consistent offset values.

Optimal Control Drives Ultrafast and Energy‐Efficient Magnetization Switching in Van der Waals Magnets

Advanced Materials, EarlyView.
ABSTRACT The accelerating expansion of data‐centric technologies is sharply increasing the energy burden of information storage, placing unprecedented pressure on the efficiency of magnetic switching. Conventional field‐driven reversal, once the foundation of magnetic memory, has become impractical in modern architectures due to its high energy cost ...

Effect of pulse-like near-fault ground motions on inelastic response of structures including foundation flexibility

, 2014
For the sites in close proximity to a causative fault where formation of near fault long period velocity pulses is conceivable, consideration of flexibility of the foundation system is very important.

Study on Long-Period Inelastic Spectra of near-Fault Pulse-Like Strong Ground Modeled Using Analytical Model

, 2011
Because the parameters of Mavroeidis analytical model of pulse-like strong ground motion have an unambiguous physical meaning, the analytical model has been calibrated using a large number of actual near-field ground-motion records, and It can ...
