Gamma-ray bursts with MeerLICHT by De Wet, Simon

“…This burst was unique for being the rst GRB with a clear rebrightening in its millimeter light curve which we attempted to explain via energy injection or a reverse shock from a late-time shell collision. Prior to the millimeter rebrightening, we found that the X-ray, optical and millimeter data could be reconciled within a standard forward shock model in a stellar wind medium, however, similar to other bursts with extensive radio data sets, no standard model could explain all of our radio data.…”

Analytical perspectives on localized solutions of the phi-4 theory by Dika, Alain

“…We investigate the topological and non-topological solitons—kink and breather—in the φ4 model. Our first objective is to explain the chaotic motion of the resonantly driven kink. …”

Computational analysis of viscoelastic fluid dynamics with applications to heat exchangers by Mavi, Anele

“…Non-Newtonian viscoelastic fluids in heat exchanger arrangements are encountered in various industrial applications such as power generation, refrigeration and in the food processing industry where the need for cooling and heating of liquids is required. The model problem is governed by complex, non-linear and coupled partial differential equations. …”

Aspects of amplitudes, gravity & complexity by Moynihan, Nathan

“…We then construct the scattering amplitudes of massive gravitons to probe the so-called van Dam-Veltman-Zakharov (vDVZ) discontinuity in a purely on-shell manner, which we again find to be in agreement with the usual result. …”

Determination of shakedown boundary and fitness-assessment-diagrams of cracked pipe bends by ElSaadany, Mostafa

“…Line Spring Elements (LSE) are embedded in quadratic shell elements to model part through cracks. Failure assessment diagrams (FAD) are developed through linking the J-integral fracture mechanics parameter with the shakedown limit moments of the analyzed cracked 90-degree pipe bend. …”
