Efimov physics beyond three particles
, 2020 Efimov physics originally refers to a system of three particles. Here we review recent theoretical progress seeking for manifestations of Efimov physics in systems composed of more than three particles. Clusters of more than three bosons are tied to each

Robust limit on a varying proton-to-electron mass ratio from a single H2 system [PDF]
, 2010 The variation of the dimensionless fundamental physical constant mu=m_p/m_e can be checked through observation of Lyman and Werner lines of molecular hydrogen in the spectra of distant QSOs.

Optimization of Pollutant Discharge Permits, Using the Trading Ratio System: A Case Study
Earth, 2022 Water quality management of rivers is one of the challenges in the analysis of water resource systems. The optimal operation of the pollutant carrying capacity of these systems provides significant economic value and could reduce treatment costs. In this

Extreme Mass Ratio Binary: Radiation reaction and gravitational waveform [PDF]
, 2005 For a successful detection of gravitational waves by LISA, it is essential to construct theoretical waveforms in a reliable manner. We discuss gravitational waves from an extreme mass ratio binary system which is expected to be a promising target of the ...

Effective role of CaO/P2O5 ratio on SiO2-CaO-P2O5 glass system
Journal of Advanced Research, 2017 In the present work, the effect of the CaO/P2O5 ratio on the composition of sol-gel synthesized 58SiO2-(19 − x)P2O5–(23 + x)CaO (x = 0, 5, 10 and 15 mol%) glass samples was studied. Further, the effect of NBO/BO ratio on hydroxy carbonated apatite layer (

Spatiotemporal complexity of a ratio-dependent predator-prey system
, 2007 In this paper, we investigate the emergence of a ratio-dependent predator-prey system with Michaelis-Menten-type functional response and reaction-diffusion. We derive the conditions for Hopf, Turing and Wave bifurcation on a spatial domain.

Likelihood Ratio Derivative Estimators For Stochastic Systems [PDF]
1989 Winter Simulation Conference Proceedings, 1989 This paper discusses Iikelihood--ratio--derivative estimation techniques for stochastic systems. After a brief review of the basic concepts, likelihood-ratio-derivative estimators are presented for the following classes of stochastic processes: time homogeneous discrete-time Markov chains, non-time-homogeneous discrete-time Markov chains, time ...
