Research progress of semiconductive shielding layer of HVDC cable
High Voltage, Volume 5, Issue 1, Page 1-6, February 2020., 2020 As an indispensable part of high‐voltage direct current (HVDC) cable, the semiconductive shielding layer plays the role of uniforming electric field in the cable. However, cable shielding materials >35 kV mainly rely on foreign imports in China, which belongs to the technical weak issues in the field of electrical materials.

The popularisation of elementary science through popular science books c.1870-c.1939 [PDF]
, 2022 This thesis investigates the popularisation of science in terms of the implicit images of science, and the explicit claims about science, which popularisers communicate through their exposition.

Recursive Matrix Calculation Paradigm by the Example of Structured Matrix
Information, 2020 In this paper, we derive recursive algorithms for calculating the determinant and inverse of the generalized Vandermonde matrix. The main advantage of the recursive algorithms is the fact that the computational complexity of the presented algorithm is ...

BeSS: An R Package for Best Subset Selection in Linear, Logistic and Cox Proportional Hazards Models
Journal of Statistical Software, 2020 We introduce a new R package, BeSS, for solving the best subset selection problem in linear, logistic and Cox's proportional hazard (CoxPH) models. It utilizes a highly efficient active set algorithm based on primal and dual variables, and supports ...

Fretting corrosion of screws contribute to the fixation failure of the femoral neck: a case report
Biosurface and Biotribology, Volume 5, Issue 4, Page 118-123, December 2019., 2019 Fretting corrosion of metal implants has been associated with implant failure and revision surgeries. This report describes the fixation failure of a femoral neck fracture in a 61‐year‐old male patient due to corrosion of three cannulated screws. Radiographic evaluation at the time of primary surgery demonstrated well‐positioning of the cannulated ...

IET Nanodielectrics, Volume 2, Issue 4, Page 129-134, December 2019., 2019 The effective permittivity of low‐density polyethylene with the conductive carbon black (CB) was modelled by COMSOL. The impact of CB content on the electric properties of the composites with different geometry of the inclusions was investigated. The modelling outcomes evidenced that the simulation was in good agreement with the experiment results at ...
