Decay rates of charmonia within a quark-antiquark confining potential [PDF]

open access: yes, 2015
In this work, we investigate the spectroscopy and decay rates of charmonia within the framework of the non-relativistic Schrödinger equation by employing an approximate inter quark-antiquark potential. The spin hyperfine, spin-orbit and tensor components

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Dynamics for wave equations connected in parallel with nonlinear localized damping

open access: yesAdvances in Nonlinear Analysis
This study investigates the properties of solutions about one-dimensional wave equations connected in parallel under the effect of two nonlinear localized frictional damping mechanisms.

VARIATIONS IN METEORIC RADIO SIGNAL DECAY RATES

open access: yes, 1963
The rate of decay of the radio signal reflected from an underdense meteor trail is usually considered to be a simple function of trail height. In fact a large scatter is found in decay rates measured by means of radar or backscatter observations and ...

On the decay rates of buffers in continuous flow lines [PDF]

open access: yes, 2000
Consider a tandem system of machines separated by infinitely large buffers. The machines process a continuous flow of products, possibly at different speeds. The life and repair times of the machines are assumed to be exponential.

Asymptotic Stability and Decay Rates of Homogeneous Positive Systems With Bounded and Unbounded Delays [PDF]

open access: yesSIAM Journal of Control and Optimization, 2014
There are several results on the stability of nonlinear positive systems in the presence of time delays. However, most of them assume that the delays are constant.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Stability on 3D Boussinesq system with mixed partial dissipation

open access: yesAdvances in Nonlinear Analysis
In the article, we are concerned with the three-dimensional anisotropic Boussinesq equations with the velocity dissipation in x2{x}_{2} and x3{x}_{3} directions and the thermal diffusion in only x3{x}_{3} direction.

Modelling memory decay after injuries using household survey data from Khartoum State, Sudan

open access: yesBMC Medical Research Methodology, 2018
Background Injuries represent an important cause of morbidity and mortality worldwide. In retrospective epidemiological studies, estimated rates of reported injuries often decline considerably when information is included from periods more than a few ...

Viral decay and production in sediments of the Mediterranean Sea

open access: yes, 2011
Here, for the first time, we have carried out synoptic measurements of viral production and decay rates in continental-shelf and deep-sea sediments of the Mediterranean Sea to explore the viral balance.
