Annular billiard dynamics in a circularly polarized strong laser field [PDF]

open access: yes, 2011
We analyze the dynamics of a valence electron of the buckminsterfullerene molecule (C60) subjected to a circularly polarized laser field by modeling it with the motion of a classical particle in an annular billiard.

Predicting the Future Burden of Renal Replacement Therapy in Türkiye Using National Registry Data and Comparative Modeling Approaches

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic kidney disease is a growing public health problem worldwide, and the number of patients requiring renal replacement therapy is steadily increasing. Türkiye has experienced a similar rise in both the incidence and prevalence of renal replacement therapy over the past decades; however, national‐level projections of future ...

Математическое моделирование автоколебаний нейрона в клеточной мембране с использованием дробной модели ФитцХью-Нагумо с функцией интенсивности раздражителя

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki
В статье проводится исследование процесса временного распространения нервного импульса в клеточной мембране. Для этой цели была предложена новая математическая модель, основанная на дробном осцилляторе ФитцХью-Нагумо с функцией интенсивности раздражителя.

Stratifications and foliations in phase portraits of gene network models

open access: yesВавиловский журнал генетики и селекции, 2023
Periodic processes of gene network functioning are described with good precision by periodic trajectories (limit cycles) of multidimensional systems of kinetic-type differential equations.

Rotation of the Trajectories of Bright soliton and Realignment of Intensity Distribution in the Coupled Nonlinear Schrodinger Equation

open access: yes, 2013
We revisit the collisional dynamics of bright solitons in the coupled Nonlinear Schrodinger equation. We observe that apart from the intensity redistribution in the interaction of bright solitons, one also witnesses a rotation of the trajectories of ...

Phase Space Structure and Transport in a Caldera Potential Energy Surface [PDF]

open access: yes, 2018
We study phase space transport in a 2D caldera potential energy surface (PES) using techniques from nonlinear dynamics. The caldera PES is characterized by a flat region or shallow minimum at its center surrounded by potential walls and multiple symmetry

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Topological polarisation states

open access: yesFrontiers in Physics, 2023
Polarisation states are described by spin expectation values, known as Stokes parameters, the trajectories of which in a rotationally symmetric system form a sphere named after Poincaré.

Fluctuating observation time ensembles in the thermodynamics of trajectories

open access: yes, 2013
The dynamics of stochastic systems, both classical and quantum, can be studied by analysing the statistical properties of dynamical trajectories. The properties of ensembles of such trajectories for long, but fixed, times are described by large-deviation

Reaction rate calculation with time-dependent invariant manifolds [PDF]

open access: yes, 2012
The identification of trajectories that contribute to the reaction rate is the crucial dynamical ingredient in any classical chemical reactivity calculation.
