Theoretical and Computational Results of a Memory-Type Swelling Porous-Elastic System
Mathematical and Computational Applications, 2022 In this paper, we consider a memory-type swelling porous-elastic system. First, we use the multiplier method to prove explicit and general decay results to solutions of the system with sufficient regularities.

Fermionic decay of a massive scalar in the early Universe
, 2019 We derive a curved space generalization of a scalar to fermion decay rate with a Yukawa coupling in expanding Friedmann-Robertson-Walker universes. This is done using the full theory of quantum fields in curved spacetime and the added-up transition ...

Instability of Ultra-Spinning Black Holes [PDF]
, 2003 It has long been known that, in higher-dimensional general relativity, there are black hole solutions with an arbitrarily large angular momentum for a fixed mass.

Stability of Excited Dressed States with Spin-Orbit Coupling
, 2013 We study the decay behaviors of ultracold atoms in metastable states with spin-orbit coupling (SOC), and demonstrate that there are two SOC-induced decay mechanisms. One arises from the trapping potential and the other is due to interatomic collision. We

General decay synchronization of delayed BAM neural networks with reaction–diffusion terms
Advances in Difference Equations, 2020 In this paper, general decay synchronization of delayed bidirectional associative memory neural networks with reaction–diffusion terms is studied. First, a useful lemma is introduced to determine the general decay synchronization of considered systems ...

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.

Dynamics of a new thermoelastic Timoshenko system with second sound
Results in Applied Mathematics, 2021 This work studies the optimal and general stability of a thermoelastic Timoshenko system with second sound. More succinctly, under some assumptions on the parameters of the system, we derive an optimal and general decay result for the solution energy of ...

Effect of dissipation on the decay-rate phase transition [PDF]
, 1998 A general condition for sharp transition of decay rate from quantum to thermal regimes is derived in dissipative tunneling models when position dependent mass is involved.
