Automatic Detection of the Cyclic Alternating Pattern of Sleep and Diagnosis of Sleep-Related Pathologies Based on Cardiopulmonary Resonance Indices

open access: yesSensors, 2022
The cyclic alternating pattern is the periodic electroencephalogram activity occurring during non-rapid eye movement sleep. It is a marker of sleep instability and is correlated with several sleep-related pathologies.

Algebraic functions with even monodromy

open access: yes, 2003
Let $X$ be a compact Riemann surface of genus $g$ and $d\geq 12g+4$ be an integer. We show that $X$ admits meromorphic functions with monodromy group equal to the alternating group $A_d.

The alternating central extension for the positive part of Uq(slˆ2)

open access: yesNuclear Physics B, 2019
This paper is about the positive part Uq+ of the quantum group Uq(slˆ2). The algebra Uq+ has a presentation with two generators A,B that satisfy the cubic q-Serre relations. Recently we introduced a type of element in Uq+, said to be alternating.

Maximal irredundant families of minimal size in the alternating group

open access: yes, 2019
Let $G$ be a finite group. A family $\mathcal{M}$ of maximal subgroups of $G$ is called `irredundant' if its intersection is not equal to the intersection of any proper subfamily.

Bimanual coordination deficits in hands following stroke and their relationship with motor and functional performance

open access: yesJournal of NeuroEngineering and Rehabilitation, 2019
Background Stroke can lead to movement disorders that affect interlimb coordination control of the bilateral upper extremities, especially the hands. However, few studies have investigated the influence of a stroke on bimanual force coordination control ...

Generating alternating groups

open access: yesHokkaido Mathematical Journal, 1997
The starting point of this paper is the claim that for any non-identity element \(x\) of the alternating group \(A_n\) there is \(y\in A_n\) such that \(\langle x,y\rangle=A_n\), made by \textit{I. M. Isaacs} and \textit{T. Zieschang} [Am. Math. Mon. 102, No. 8, 734-739 (1995; Zbl 0846.20004)]. A proof of this theorem is given here. It uses some lemmas

Experimental Study on Mechanical Deformation Characteristics of Inclined and Straight Alternating Pile Groups

open access: yesAdvances in Civil Engineering, 2020
In order to investigate the bearing characteristics of inclined straight alternating pile groups under vertical and horizontal loads, the indoor model test of 2 × 2 inclined straight alternating pile groups with two layers of soil on low pile caps was ...

Alternating forms and one-relator groups [PDF]

open access: yesProceedings of the American Mathematical Society, 1974
This paper considers epimorphisms of finitely generated one-relator groups G = F / R , F G = F/R,F free, R ⊆ F p [ F , F ] R \subseteq {F^p}[F,F] for some

Alternatives for pseudofinite groups [PDF]

open access: yesJournal of Group Theory, 2013
Abstract.The famous Tits alternative states that a linear group either contains a non-abelian free group or is soluble-by-(locally finite). In this paper we study similar alternatives in pseudofinite groups.
