Evolutionary rescue in a fluctuating environment: periodic versus quasi-periodic environmental changes [PDF]
, 2023 No environment is constant over time, and environmental fluctuations impact the outcome of evolutionary dynamics. Survival of a population not adapted to some environmental conditions is threatened unless, for example, a mutation rescues it, an eco ...

Probabilistic properties of a Markov-switching periodic $GARCH$ process [PDF]
, 2019 summary:In this paper, we propose an extension of a periodic $GARCH$ ($PGARCH$) model to a Markov-switching periodic $GARCH$ ($MS$-$PGA$ $RCH$), and provide some probabilistic properties of this class of models.

Fine-scale species delimitation: speciation in process and periodic patterns in nudibranch diversity [PDF]
ZooKeys, 2020 Using the nudibranch genus Amphorina as a model, ongoing speciation is demonstrated, as well as how periodic-like patterns in colouration can be included in an integrated method of fine-scale species delimitation.

A Super-Algebraically Convergent, Windowing-Based Approach to the Evaluation of Scattering from Periodic Rough Surfaces [PDF]
, 2008 We introduce a new second-kind integral equation method to solve direct rough surface scattering problems in two dimensions. This approach is based, in part, upon the bounded obstacle scattering method that was originally presented in Bruno et al. [2004]

Friction and adhesive wear behavior caused by periodic impact in mixed-lubricated point contacts
Advances in Mechanical Engineering, 2020 Periodic impact is a common phenomenon experienced by functional components. The mechanisms governing the adhesive wear growth caused by the periodic impact are not well understood, which limits the development of antiwear and lubricating behavior.

Stability and Almost Periodicity of Trajectories of Periodic Processes
Journal of Differential Equations, 1995 Based on the De Leeuw-Glicksberg decomposition theorem, the author proves that if the monodromy operator \(V\) is power-bounded and its spectrum \(\sigma (V)\) has countable intersection with the unit circle \(\Gamma\), and the point spectrum \(P \sigma (V^*)\) of \(V^*\) satisfies a certain condition, then all solutions on \(\mathbb{R}_ +\) of (1) \(u'

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Cerebellar ataxia after pediatric brain tumor treatment can cause persistent gait, balance, and speech impairment, yet no established rehabilitation strategy exists. Somato‐cognitive coordination therapy (SCCT) is a virtual reality–guided intervention designed to promote sensorimotor integration through visually constrained reaching

On double periodic non-homogeneous poisson processes [PDF]
, 2002 Non-homogenous Poisson processes with periodic claim intensity rate are proposed as the claim counting process of risk theory. We introduce a doubly periodic Poisson model with short and long term trends, illustrated by a double-beta intensity function ...

Bifurcation dynamics of Sherman neuron under magnetic flow effect
Journal of Measurement Science and Instrumentation, 2023 The bifurcation behavior of Sherman neuron system under the influence of magnetron memristor is analyzed. Taking the membrane potential reversal voltages VCa and VK of islet β-cell neuron model as bifurcation parameters, the inter-spike interval ...
