The Problem of Bicenter and Isochronicity for a Class of Quasi Symmetric Planar Systems
Abstract and Applied Analysis, 2014 We study a class of quasi symmetric seventh degree systems and obtain the conditions that its two singular points can be two centers at the same step by careful computing and strict proof. In addition, the condition of an isochronous center is also given.

Cyclo-P<sub>5</sub> <sup>-</sup> Revisited: The Surprisingly Stable Uncoordinated Pentaphospholide Anion. [PDF]
Angew Chem Int Ed EnglThe intriguing cyclo‐P5− anion, which is isolobal to the well‐known cyclopentadienide anion, was characterized for the first time crystallographically in the salts [M([2.2.2]cryptand)][cyclo‐P5] (M = Na, K). The compounds were further characterized by UV/Vis spectroscopy in solution and in the solid state by Raman and 31P MAS NMR spectroscopy ...

Journal of Nonlinear Mathematical Physics, 2021 The authors consider a Hamiltonian system of \(2N+2\) oscillators. They exhibit the solutions of its initial value problem. In the classical context the solutions are completely periodic for arbitrary initial data. In the quantal context the infinitely degenerate spectrum is equispaced. All the corresponding eigenfunctions are also exhibited.

Regulârnaâ i haoticeskaâ dinamika, 2021 Our main result is the complete set of explicit conditions necessary and sufficient for isochronicity of a Hamiltonian system with one degree of freedom. The conditions are presented in terms of Taylor coefficients of the Hamiltonian function.

Enhanced control of periodontitis by an artificial intelligence-enabled multimodal-sensing toothbrush and targeted mHealth micromessages: A randomized trial. [PDF]
J Clin PeriodontolAbstract Aim Treatment of periodontitis, a chronic inflammatory disease driven by biofilm dysbiosis, remains challenging due to patients' poor performance and adherence to the necessary oral hygiene procedures. Novel, artificial intelligence‐enabled multimodal‐sensing toothbrushes (AI‐MST) can guide patients' oral hygiene practices in real‐time and ...

Temporal Dynamics With and Without a Nervous System: Plant Physiology, Communication, and Movement. [PDF]
Cogn SciAbstract The concept of time has long been the subject of complex philosophical reflections and scientific research, which have interpreted it differently based on the starting question, context, and level of analysis of the system under investigation.

International Journal of Geometric Methods in Modern Physics, 2014 The possibility has been recently demonstrated to manufacture (nonrelativistic, Hamiltonian) many-body problems which feature an isochronous time evolution with an arbitrarily assigned period T yet mimic with good approximation, or even exactly, any given many-body problem (within a large, physically relevant, class) over times [Formula: see text ...
