Expansivity and Shadowing in Linear Dynamics [PDF]
, 2016 In the early 1970's Eisenberg and Hedlund investigated relationships between expansivity and spectrum of operators on Banach spaces. In this paper we establish relationships between notions of expansivity and hypercyclicity, supercyclicity, Li-Yorke ...

Limit Average Shadowing and Dominated Splitting
پژوهشهای ریاضی, 2020 Introduction The influence of persistence behavior of a dynamical system on tangent bundle of a manifold is always a challenge in dynamical systems. Persistence properties have been studied on whole manifold or on some pieces with independent dynamics ...

Outage Analysis of Mixed FSO/WiMAX Link
IEEE Photonics Journal, 2016 In this paper, we study the outage performance of a complex system consisting of a free-space optical (FSO)/radio-frequency (RF) link. Using radio over free-space optics technology, the FSO link carries Worldwide Interoperability for Microwave Access ...

On the genericity of the shadowing property for conservative homeomorphisms [PDF]
Proceedings of the American Mathematical Society, 2016 We prove the genericity of the shadowing and periodic shadowing properties for both conservative and dissipative homeomorphisms on a compact connected manifold. Our proof is valid for topological manifolds and still holds in the dissipative case.

N-expansive homeomorphisms with the shadowing property [PDF]
, 2016 We discuss the dynamics of $n$-expansive homeomorphisms with the shadowing property defined on compact metric spaces. For every $n\in\mathbb{N}$, we exhibit an $n$-expansive homeomorphism, which is not $(n-1)$-expansive, has the shadowing property and ...

Social Neuroscience, 2006 The recent finding that Broca's area, the motor center for speech, is activated during action observation lends support to the idea that human language may have evolved from neural substrates already involved in gesture recognition. Although fascinating, this hypothesis can be questioned because while observing actions of others we may evoke some ...

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.

A sum-of-sinusoids based simulation model for the joint shadowing process in urban peer-to-peer radio channels [PDF]
, 2005 Most conventional channel models are not capable of capturing the joint spatial correlation of shadowing processes between a large number of meshed radio channels in an ad-hoc wireless communications network. In this paper, we present a sum-of-sinusoids (

Error Performance of DDPSK Receiver in the Presence of Composite Fading
IEEE AccessWe investigate the justification for implementing double differential phase-shift keying (DDPSK) instead of differential phase-shift keying (DPSK) in the presence of carrier frequency offset (CFO) over wireless channels affected by thermal noise ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Rates of cancer among adolescents and young adults (AYA), age 15–39 years, are increasing. Consequently, radiation oncologists are treating more AYAs who have diagnoses spanning both pediatric and adult practices. Compared to pediatric and older adult patients, AYAs face a unique set of challenges.
