Real-time dynamic articulations in the 2-D waveguide mesh vocal tract model [PDF]
, 2006 Time domain articulatory vocal tract modeling in one-dimensional (1-D) is well established. Previous studies into two-dimensional (2-D) simulation of wave propagation in the vocal tract have shown it to present accurate static vowel synthesis.

Banach Journal of Mathematical Analysis, 2011 The author gives an elementary proof of the small dimension lemma: If \(K\) is a closed, irreducible subgroup of \(SU(n)\), where \(n\in\mathbb{N}\), such that \(k+ k^{-1}\in\mathbb{C} I\) for all \(k\in K\), then \(n=1\), or \(n=2\) and \(K\subseteq SU(2)\).

Large anisotropy of spin-orbit interaction in a single InAs self-assembled quantum dot
, 2009 Anisotropy of spin-orbit interaction (SOI) is studied for a single uncapped InAs self-assembled quantum dot (SAQD) holding just a few electrons. The SOI energy is evaluated from anti-crossing or SOI induced hybridization between the ground and excited ...

Derivatives of tangent function and tangent numbers
, 2015 In the paper, by induction, the Fa\`a di Bruno formula, and some techniques in the theory of complex functions, the author finds explicit formulas for higher order derivatives of the tangent and cotangent functions as well as powers of the sine and ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Emerging evidence suggests that low‐frequency neural oscillations are dynamically regulated by consciousness levels, with the recovery of low cortical activity potentially serving as a neurophysiological substrate for conscious emergence. Targeted enhancement of these low‐frequency rhythms in patients with disorders of consciousness

On the Superstability Related with the Trigonometric Functional Equation
Advances in Difference Equations, 2009 We will investigate the superstability of the (hyperbolic) trigonometric functional equation from the following functional equations: , , , , which can be considered the mixed functional equations of the sine function and cosine function, of the ...

Adaptive channel estimation for cognitive fully adaptive radar
IET Radar, Sonar & Navigation, 2022 The paper addresses channel state information estimation for a cognitive radar system. The underlying radar signal model considered in this paper is based on a stochastic Green's function approach. In the radar model, the clutter returns can be expressed

Optical vortices with an infinite number of screw dislocations
Компьютерная оптика, 2021 In optical data transmission with using vortex laser beams, data can be encoded by the topological charge, which is theoretically unlimited. However, the topological charge of a single separate vortex (screw dislocation) is limited by possibilities of ...

Operator Cosine Functions and Boundary Value Problems
Doklady Mathematics, 2019 For the first time, the theory of strongly continuous operator cosines of functions (COF) is applied to the study of the correct solvability of boundary value problems for second-order linear differential equations in Banach space (elliptic case). Usually in COF terms the correct solvability of the Cauchy problem (hyperbolic case) is formulated.
