An Exact Solution of the Binary Singular Problem

Journal of Function Spaces, 2014
Singularity problem exists in various branches of applied mathematics. Such ordinary differential equations accompany singular coefficients. In this paper, by using the properties of reproducing kernel, the exact solution expressions of dual singular ...

Generalized Darboux transformations for the KP equation with self-consistent sources

, 2004
The KP equation with self-consistent sources (KPESCS) is treated in the framework of the constrained KP equation. This offers a natural way to obtain the Lax representation for the KPESCS.

Efficient Photodegradation of Dyes from Single and Binary Aqueous Solutions Using Copper(II) Coordination Polymers

Molecules
The present study reports the application of three copper(II) coordination polymers, namely 1∞[Cu3L2(N3)] CH3COO (CP1), 1∞[Cu3L2(NO3)]NO3·2CH3OH·2H2O (CP2), and 1∞[Cu3L2(H2O)](ClO4)2 (CP3), where H2L stands for N,N′-bis[(2-hydroxybenzilideneamino)propyl]-

Analytical, Statistical Approximate Solution of Dissipative and Nondissipative Binary-Single Stellar Encounters

Physical Review X, 2021
We present a statistical approximate solution of the bound, nonhierarchical three-body problem, and extend it to a general analysis of encounters between hard binary systems and single stars.

New code for equilibriums and quasiequilibrium initial data of compact objects. II. Convergence tests and comparisons of binary black hole initial data

, 2012
COCAL is a code for computing equilibriums or quasiequilibrium initial data of single or binary compact objects based on finite difference methods. We present the results of supplementary convergence tests of COCAL code using time symmetric binary black ...

Studies on the Deviation of a Solution from the Hypothetical Ideal Solution with the Total Activity Coefficient

Molecules
The total activity coefficient is exploited to study the deviation of a solution from the hypothetical ideal solution. It is proven for a solution that the curve of the total activity coefficient and all curves of activity coefficients of components will

An approximate binary-black-hole metric [PDF]

, 2000
An approximate solution to Einstein's equations representing two widely-separated non-rotating black holes in a circular orbit is constructed by matching a post-Newtonian metric to two perturbed Schwarzschild metrics. The spacetime metric is presented in

Photometric solutions of some contact ASAS binaries [PDF]

New Astronomy, 2016
We present the first light curve solution of 6 contact binary systems which are chosen from the ASAS catalog. The photometric elements and the estimated absolute parameters of all systems are obtained with the light curve analyses. We calculated the values of degree of contact for the systems.

Demonstration of Solute-specific Synergism in Binary Solvents

Journal of Fluorescence, 2022
Abstract The structure and solvation behaviour of binary liquid mixtures of Methanol (MeOH) and N, N-Dimethylformamide (DMF) are explored by ascertaining their intermolecular interactions with either Rhodamine-B (RhB) or Rhodamine101 (Rh101) dye through steady-state absorption, emission, and two-photon induced fluorescence. Specifically, in the

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.
