Bifurcation of limit cycles for a class of quintic Hamiltonian systems with quartic perturbed terms
上海师范大学学报. 自然科学版, 2022 By using the method of detection function and numerical calculation, the bifurcation of limit cycles for a class of quintic Hamiltonian systems under quartic perturbations was studied.

Dynamic analysis of unilateral diffusion Gompertz model with impulsive control strategy
Advances in Difference Equations, 2018 In this paper, we establish a unilateral diffusion Gompertz model of a single population in two patches in a theoretical way. Firstly, we prove the existence and uniqueness of an order-one periodic solution by the geometry theory of differential ...

CoRRRhythmic fluctuations in acoustic energy and accompanying neuronal excitations in cortical oscillations are characteristic of human speech, yet whether a corresponding rhythmicity inheres in the articulatory movements that generate speech remains unclear.

Limit cycles in four dimensions [PDF]
Journal of High Energy Physics, 2012 We present an example of a limit cycle, i.e., a recurrent flow-line of the beta-function vector field, in a unitary four-dimensional gauge theory. We thus prove that beta functions of four-dimensional gauge theories do not produce gradient flows. The limit cycle is established in perturbation theory with a three-loop calculation which we describe in ...

Analysing panel flutter in supersonic flow by Hopf bifurcation [PDF]
Iranian Journal of Numerical Analysis and Optimization, 2014 This paper is devoted to study of a partial differential equation governing panel motion in supersonic flow. This PDE can be transformed to an ODE by means of a Galerkin method.

The plastic limit of clays [PDF]
, 2013 The plastic limit of soils was first described by Atterberg in 1911. The thread-rolling test was standardised at the US Public Roads Bureau in the 1920s and 1930s, and has subsequently become one of the standard tests of soil mechanics.

Solid Pseudopapillary Neoplasm of the Pancreas in Children and Adolescents: Expert Recommendations
Pediatric Blood &Cancer, EarlyView.ABSTRACT Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare low‐grade malignant exocrine pancreatic tumor, mostly discovered during the second decade of life in females, with a very good prognosis, provided microscopically complete surgical excision is achieved.
