We discuss decay of unstable particles and pair annihilation of stable heavy particles that occur in the cosmic medium, from the point of the fundamental microscopic theory. A fully quantum mechanical treatment shows that the effect of thermal environment on these processes cannot be described in terms of quantities on the mass shell alone, thus requiring an extention of the Boltzmann-like equa...

AIM To compare the predictive outcome of ocular burns using two different prognostic classification systems, that is, Dua and Roper Hall classification. PATIENTS AND METHODS In a prospective, randomised, controlled clinical trial, the extent of acute ocular burns in 100 patients was graded by Roper Hall and Dua classifications. Patients were randomised in two groups of 50 each to receive conv...

We investigate the one pion decay of Roper resonance ${N}^{*}(1440)\ensuremath{\rightarrow}N\ensuremath{\pi}$ in Sakai-Sugimoto model holographic QCD. The nucleon and emerge as ground first excited states collective radial motion instanton four dimensional space with extra dimension. It is found that ratio $\ensuremath{\pi}N{N}^{*}$ $\ensuremath{\pi}NN$ couplings, hence ${g}_{A}^{N{N}^{*}}$ ${g...

‎In this short note‎, ‎we present some inequalities for relative operator entropy which are generalizations of some results obtained by Zou [Operator inequalities associated with Tsallis relative operator entropy‎, ‎{em Math‎. ‎Inequal‎. ‎Appl.}‎ ‎{18} (2015)‎, ‎no‎. ‎2‎, ‎401--406]‎. ‎Meanwhile‎, ‎we also show some new lower and upper bounds for relative operator entropy and Tsallis relative o...

We discuss the analysis of data from πN elastic scattering and single pion photoand electroproduction. The main focus is a study of low-lying non-strange baryon resonances. Here we concentrate on some difficulties associated with resonance identification, in particular the Roper and higher P11 states.

In this article we propose a generalisation of the recent work of Gatheral-Jacquier [11] on explicit arbitrage-free parameterisations of implied volatility surfaces. We also discuss extensively the notion of arbitrage freeness and Roger Lee’s moment formula using the recent analysis by Roper [18]. We further exhibit an arbitrage-free volatility surface different from Gatheral’s SVI parameterisa...

Sixty-six consecutive cases undergoing enucleation with the insertion of the Roper-Hall magnetic implant at the Birmingham and Midland Eye Hospital (BMEH) were followed up to re-establish the rate of extrusion. It was possible to study the records of all 66 patients. An extrusion rate of 1.5% was found.
