IET Generation, Transmission &Distribution, Volume 17, Issue 9, Page 2038-2054, May 2023., 2023 A co‐phase power supply system with hybrid energy storage system (HESS) for electrified railway is studied. A bi‐level optimization model considering battery degradation to obtain both optimal sizing and operation of HESS is proposed. The proposed model includes a novel real‐time energy management scheme (EMS); the lower level is built as a dynamic ...

Aging Cell, Volume 22, Issue 5, May 2023., 2023 The immune system plays a central role in aging. The findings illustrated that the innate immune system plays critical roles in shaping extreme health span and longevity. Monocytes from long‐lived individuals reveal enhanced life‐cycles and a M2‐like phenotype, which are associated with an insulin‐driven immune‐metabolic network that supports multiple ...

Influence analysis of calculated horizontally layered soil parameters on grounding parameters
High Voltage, Volume 8, Issue 2, Page 421-430, April 2023., 2023 Abstract Calculated parameters (soil layer resistivity, soil layer thickness, and the number of soil layers) of horizontally layered soil are usually obtained based on the measured apparent resistivity under different measurement distances, which are significant for the design, operation, and maintenance of grounding grids.

A novel approach to touch voltage risk assessment for gas pipelines in shared transmission corridors
IET Science, Measurement &Technology, Volume 17, Issue 1, Page 27-36, January 2023., 2023 Abstract Touch voltages are more likely to appear on long‐distance pipelines that lie in shared corridors with transmission lines. The touch voltage level varies with soil resistivity and can become hazardous while maintenance is being undertaken, necessitating risk assessment.
