The braking index of millisecond magnetars [PDF]

open access: yes, 2017
We make the first measurement of the braking index $n$ of two putative millisecond magnetars born in short gamma-ray bursts. We measure $n=2.9\pm0.1$ and $n=2.6\pm0.1$ for millisecond magnetars born in GRB 130603B and GRB 140903A respectively.

Differential rotation decay in the radiative envelopes of CP stars

open access: yes, 2002
Stars of spectral classes A and late B are almost entirely radiative. CP stars are a slowly rotating subgroup of these stars. It is possible that they possessed long-lived accretion disks in their T Tauri phase.

Close binary evolution I. The tidally induced shear mixing in rotating binaries

open access: yes, 2013
We study how tides in a binary system induce some specific internal shear mixing, able to substantially modify the evolution of close binaries prior to mass transfer. We construct numerical models accounting for tidal interactions, meridional circulation,

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

open access: yesAdvanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Can Ti‐Based MXenes Serve as Solid Lubricants for Brake Applications? A Tribological Study

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the first implementation of Ti‐based MXenes materials in brake pad friction composite material. The resulting composite material exhibits a 48% reduction in the wear rate; alongside significant improvements are observed for thermal and mechanical properties.

Research and Application of Distributed Automatic Test Technology for Line Longitudinal Difference

open access: yesJournal of Harbin University of Science and Technology, 2022
Aiming at the problems of the joint debugging test of optical fiber differential protection, the two terminal testers can not achieve synchronous control, and carry out the fault test of both sides and automatic test of ratio braking characteristics.
