Dissipative periodic processes [PDF]
Bulletin of the American Mathematical Society, 1971 Abstract : The objective of this paper is to develop a general and meaningful theory of dissipative periodic systems. For ordinary periodic differential equations one studies the iterates of a map T of a state space into itself where the map T is topological and the space is locally compact (n-dimensional Euclidean space). However, for the applications

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.

Computational Methods for Periodic Systems - An Overview [PDF]
, 2001 We present an up-to-date survey of numerical methods for the analysis and design of linear discrete-time periodic systems. The basic tool is the periodic Schur form and its variants, for which a certain form of numerical stability can be ...

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.

Periodic-GP: Learning Periodic World with Gaussian Process Bandits
CoRR, 2021 We consider the sequential decision optimization on the periodic environment, that occurs in a wide variety of real-world applications when the data involves seasonality, such as the daily demand of drivers in ride-sharing and dynamic traffic patterns in transportation. In this work, we focus on learning the stochastic periodic world by leveraging this

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.

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 ...

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'

Comparative Drug Response Profiling in Neuroblastoma Cell Lines and Patient‐Derived Tumor Organoids
Pediatric Blood &Cancer, EarlyView.ABSTRACT High‐risk neuroblastoma remains a leading cause of pediatric cancer mortality, and improved preclinical models are needed to guide therapeutic developments. We screened seven high‐risk neuroblastoma cell lines and three patient‐derived tumor organoids with 528 compounds alongside bone marrow controls, and compared them with external datasets ...

Design of Fault Detection Filters for Periodic Systems [PDF]
, 2004 We propose a numerically reliable computational approach to design fault detection filters for periodic systems. This approach is based on a new numerically stable algorithm to compute least order annihilators without explicitly building time-invariant ...
