Experimental Study on Mechanical Properties of Fiber Recycled Concrete

Renmin Zhujiang, 2022
In this paper,the influence of fiber types on the mechanical properties of recycled concrete materials is analyzed by controlling the fiber types in recycled concrete materials.Then,the influence of the diameter,length,and mass ratio of polypropylene ...

Dissipation in extreme mass-ratio binaries with a spinning secondary [PDF]

Physical Review D, 2019
We present the gravitational-wave flux balance law in an extreme mass-ratio binary with a spinning secondary. This law relates the flux of energy (angular momentum) radiated to null infinity and through the event horizon to the local change in the ...

Binary black hole merger in the extreme mass ratio limit [PDF]

, 2006
We discuss the transition from quasi-circular inspiral to plunge of a system of two nonrotating black holes of masses $m_1$ and $m_2$ in the extreme mass ratio limit $m_1m_2\ll (m_1+m_2)^2$.

Mechanistic basis for inhibition of the extended‐spectrum β‐lactamase GES‐1 by enmetazobactam and tazobactam

FEBS Letters, EarlyView.
Antimicrobial resistance (AMR) is of huge importance, resulting in over 1 million deaths each year. Here, we describe how a new drug, enmetazobactam, designed to help fight resistant bacterial diseases, inhibits a key enzyme (GES‐1) responsible for AMR. Our data show it is a more potent inhibitor than the related tazobactam, with high‐level computation

Resonantly enhanced kicks from equatorial small mass-ratio inspirals

, 2014
We calculate the kick generated by an eccentric black hole binary inspiral as it evolves through a resonant orbital configuration where the precession of the system temporarily halts.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Probing boson stars with extreme mass ratio inspirals [PDF]

Journal of Cosmology and Astroparticle Physics, 2019
We propose to use gravitational waves from extreme mass ratio inspirals (EMRI), composed of a boson star and a supermassive black hole in the center of galaxies, as a new method to search for boson stars.
