Science with the TianQin observatory: Preliminary result on extreme-mass-ratio inspirals [PDF]

open access: yes, 2020
Systems consisting of a massive black hole and a stellar-origin compact object (CO), known as extreme-mass-ratio inspirals (EMRIs), are of great significance for space-based gravitational-wave detectors, as they will allow for testing gravitational ...

Accretion disc dynamics in extreme mass ratio compact binaries [PDF]

open access: yes, 2007
An analysis is presented of a numerical investigation of the dynamics and geometry of accretion discs in binary systems with mass ratios q < 0.1, applicable to ultra-compact X-ray binaries, AM CVn stars and very short period cataclysmic variables.

Considerations on similarity condition of wing deformation in flapping for model and mosquito wings

open access: yesJournal of Biomechanical Science and Engineering, 2019
In our previous paper, to simulate mosquito flapping flight, experiments were performed using a wing model, which had n-times (n=10) enlarged shape of the mosquito wing and was made of deformable elastic material.

Maximized Energy Density of RuO2//RuO2 Supercapacitors through Potential Dependence of Specific Capacitance

open access: yesChemElectroChem, 2020
In this study, a stepwise cyclic voltammetry approach was proposed to clarify the potential dependence of specific capacitance for reduced graphene oxide and ruthenium oxide electrodes. Based on the relationship between specific capacitance and potential,
