A period distribution of X-ray binaries observed in the central region of M31 with Chandra and HST
, 2012 Almost all Galactic black hole binaries with low mass donor stars are transient X-ray sources; we expect most of the X-ray transients observed in external galaxies to be black hole binaries also.

, 2018 The Heliospheric Imagers (HI) on board the two spacecraft of the Solar Terrestrial Relations Observatory (STEREO) provided white-light images of transients in the solar wind from dual perspectives from 2007 to 2014. In this paper, we develop a new method

Detection of 25 new rotating radio transients at 111 MHz
, 2018 Nearly all fast radio RRAT-type transients that are pulsars with rare pulses have been previously detected using decimetre wavelengths. We present here 34 transients detected at metre wavelengths in our daily monitoring at declinations -9o < decl. < +42o.

Very long transients in globally coupled maps [PDF]
, 1999 Very long transients are found in the partially ordered phase of type II of globally coupled logistic maps. The transients always lead the system in this phase to a state with a few synchronous clusters.

Further Improvements in Topological Transformer Model Covering Core Saturation
IEEE Access, 2022 This paper is devoted to improvements of the low-frequency topological model of a three-legged stacked-core transformer. It is shown that $B-H$ hysteresis loops employed in the transformer model and $\Psi -i$ curves measured at transformer terminals ...

Phase 1 repolarization rate defines Ca2+ dynamics and contractility on intact mouse hearts. [PDF]
, 2019 In the heart, Ca2+ influx through L-type Ca2+ channels triggers Ca2+ release from the sarcoplasmic reticulum. In most mammals, this influx occurs during the ventricular action potential (AP) plateau phase 2.

AIP Advances, 2019 Selective laser melting (SLM) produces complex physical behaviors. After laser melting, the molten pool condenses with an uneven surface, which influences the next powder spreading process and affects the quality of the final product.

Impeller Optimized Design of the Centrifugal Pump: A Numerical and Experimental Investigation
Energies, 2018 Combined numerical simulation with experiment, blade wrap angle, and blade exit angle are varied to investigate the optimized design of the impeller of centrifugal pump. Blade wrap angles are 122°, 126°, and 130°. Blade exit angles are 24°
