The Egyptian Journal of Bronchology, 2022 Background Periodic leg movement disorder is defined as periodic episodes of repetitive limb movements during sleep that mainly occurs in the lower limb, including the hips, knees, and toes, and sometimes affects the upper limb.

On the fixed points of a Hamiltonian diffeomorphism in presence of fundamental group [PDF]
, 2014 Let M be a weakly monotone symplectic manifold, and H be a time-dependent Hamiltonian; we assume that the periodic orbits of the corresponding time-dependent Hamiltonian vector field are non-degenerate.

ON A CARLEMAN PROBLEM IN THE CASE OF A DOUBLY PERIODIC GROUP
Проблемы анализа, 2022 Let Г be a doubly periodic group whose fundamental region 𝐷 is a rectangle, in which the ratio of the largest side to the shortest one does not exceed 3.

A bound on the group velocity for Bloch wave packets [PDF]
, 2015 We give a direct proof that the group velocities of Bloch wave packet solutions of periodic second order wave equations cannot exceed the maximal speed of propagation of the periodic wave ...

Almost periodic transformation groups [PDF]
Transactions of the American Mathematical Society, 1937 1. In view of the recent work on topological groups it is natural to consider the situation which arises when such groups act as transformation groups on various types of spaces. Such a study is begun here from the point of view of almost periodic transformation groups, the definition of which is suggested by von Neumann's paper on almost periodic ...

Periodic Mesoporous Organosilica Nanoparticles with BOC Group, towards HIFU Responsive Agents
Molecules, 2020 Periodic Mesoporous Organosilica Nanoparticles (PMONPs) are nanoparticles of high interest for nanomedicine applications. These nanoparticles are not composed of silica (SiO2). They belong to hybrid organic−inorganic systems.

Periodic rings with finitely generated underlying group
International Journal of Mathematics and Mathematical Sciences, 2004 We study periodic rings that are finitely generated as groups. We prove several structure results. We classify periodic rings that are free of rank at most 2, and also periodic rings R such that R is finitely generated as a group and R/t(R)≃ℤ.

On Periodic Groups and Shunkov Groups that are Saturated by Dihedral Groups and $A_5$
Известия Иркутского государственного университета: Серия "Математика", 2017 A group is said to be periodic, if any of its elements is of finite order. A Shunkov group is a group in which any pair of conjugate elements generates Finite subgroup with preservation of this property when passing to factor groups by finite Subgroups ...

Groups with Subnormal Deviation
Mathematics, 2023 The structure of groups which are rich in subnormal subgroups has been investigated by several authors. Here, we prove that if a periodic soluble group G has subnormal deviation, which means that the set of its non-subnormal subgroups satisfies a very ...
