Automated Creak Identifies Laryngeal Dystonia During Conversational Speech
This study evaluated whether automated creak distinguished speakers with adductor laryngeal dystonia (AdLD), muscle tension dysphonia (MTD), and those without voice disorders during conversational speech. Automated creak estimates were able to differentiate speakers with AdLD from MTD and controls with similar performance across different types of ...

Research of hieroglyphic signs using audiovisual digital analysis methods
A study of ancient written texts and signs showed that the hieroglyphs and structure of the archaic sentence have much in common with the modern Chinese language.

On Non‐Compact Extended Bach Solitons
ABSTRACT We study the characterization of non‐compact solitons of the extended Bach flow, known as an extended Bach soliton. We prove that a weakly conformally flat extended Bach soliton (Mn,g,V)$(M^n,g,V)$ with harmonic Weyl tensor is Bach‐flat and the potential vector field V$V$ is conformal.

Polyrhythms in the Brain: Metrical Priming, Acoustic Balance, and Perceptual Biases
This study investigates whether metrical priming modifies the neural responses to the beat of polyrhythms. After balancing the acoustic energy related to the two beat periodicities, we measured the neural activity synchronized to each primed beat using frequency tagging.

Experimental characteristics of spatial subharmonics in BSO
The generation of spatial subharmonics in BSO is characterized experimentally. The frequency shift of the subharmonic beam is measured in heterodyne detection, threshold values for the subharmonic generation are measured, and the optimum frequency shift ...

Boundary unique continuation in planar domains by conformal mapping
Abstract Let Ω⊂R2$\Omega \subset \mathbb {R}^2$ be a chord arc domain. We give a simple proof of the the following fact, which is commonly known to be true: a nontrivial harmonic function which vanishes continuously on a relatively open set of the boundary cannot have the norm of the gradient which vanishes on a subset of positive surface measure (arc ...

The universal family of punctured Riemann surfaces is Stein
Abstract We show that the universal Teichmüller family V(g,n)$V(g,n)$ of compact Riemann surfaces of genus g⩾0$g\geqslant 0$ with n>0$n>0$ punctures is a Stein manifold. We describe its basic function‐theoretic properties and pose some challenging questions. We show, in particular, that the space of fibrewise algebraic functions on the universal family

Power losses and windings temperature of an induction machine under voltage subharmonics
This paper deals with the effect of voltage subharmonics on power losses and heating of an induction motor. An increase in power losses in stator and rotor windings and their impact on windings temperature is presented for subharmonics of various ...

Modeling of subharmonics and chaos in DC motor drives [PDF]
In this paper, the nonlinear dynamics of both voltage-mode and current-mode controlled dc motor drive systems are presented. The investigation is based on the derivation of the discrete mappings that describe their system subharmonics and chaos in the ...
