Discrepancies in Atomic Data and Suggestions for Their Resolutions

open access: yesAtoms, 2017
The analysis and modelling of a range of plasmas (for example, astrophysical, laser- produced and fusion) require atomic data for a number of parameters, such as energy levels, radiative rates and electron impact excitation rates, or equivalently, the ...

Journey of a Lifetime [PDF]

open access: yesFamily Medicine and Community Health, 2019
As I work with medical students and family medicine residents at the University of Virginia (UVA) School of Medicine, I remind them that they are where I was four decades ago, and I am where they will be in four decades.

Bounds on the Lifetime Expectations of Series Systems with IFR Component Lifetimes

open access: yesEntropy, 2021
We consider series systems built of components which have independent identically distributed (iid) lifetimes with an increasing failure rate (IFR). We determine sharp upper bounds for the expectations of the system lifetimes expressed in terms of the ...

Lifetime of kaonium [PDF]

open access: yesPhysical Review D, 2004
The kaon--antikaon system is studied in both the atomic and the strongly interacting sector. We discuss the influence of the structures of the $f_0(980)$ and the $a_0(980)$ mesons on the lifetime of kaonium. The strong interactions are generated by vector meson exchange within the framework of the standard $SU(3)_V\times SU(3)_A$ invariant effective ...

Second-Order Phase Transition in Counter-Rotating Taylor–Couette Flow Experiment

open access: yesEntropy, 2020
In many basic shear flows, such as pipe, Couette, and channel flow, turbulence does not arise from an instability of the laminar state, and both dynamical states co-exist.

Enhancing Emission via Radiative Lifetime Manipulation in Ultrathin InGaN/GaN Quantum Wells: The Effects of Simultaneous Electric and Magnetic Fields, Thickness, and Impurity

open access: yesNanomaterials, 2023
Ultra-thin quantum wells, with their unique charge confinement effects, are essential in enhancing the electronic and optical properties crucial for optoelectronic device optimization.

Inverse change in positron lifetimes of vacancies in tungsten by binding of interstitial impurity atoms to a vacancy: A first-principles study

open access: yesNuclear Materials and Energy, 2023
First-principles calculations related to defect complexes formed from a monovacancy and multiple interstitial impurity atoms (hydrogen, carbon, nitrogen, and oxygen atoms) in tungsten were performed.
