This paper explores whether a speaker's voice quality, de®ned as the perceived timbre of someone's speech, changes as a function of variation in speech melody. Analyses are based on several productions of the vowel `a', provided with di€erent intonation patterns. It appears that in general fundamental frequency covaries with the `strength relationship' between the ®rst two harmonics (H1±H2). Th...

In this paper, we present new variants of global bi-conjugate gradient (Gl-BiCG) and global bi-conjugate residual (Gl-BiCR) methods for solving nonsymmetric linear systems with multiple right-hand sides. These methods are based on global oblique projections of the initial residual onto a matrix Krylov subspace. It is shown that these new algorithms converge faster and more smoothly than the Gl-...

We extend the BMS(4) group by adding logarithmic supertranslations. This is done relaxing boundary conditions on metric and its conjugate momentum at spatial infinity in order to allow terms of carefully designed form asymptotic expansion, while still preserving finiteness action. Standard theorems Hamiltonian formalism are used derive (finite) generators As ordinary supertranslations, these de...

\begin{abstract} Let $P\pm$ be the Riesz's projection operator and let $P_-= I - P_+$. We consider estimates of expression $\|( |P_ + f | ^s |P_- |^s) ^{\frac{1}{s}}\|_{L^p (\mathbf{T})}$ in terms Lebesgue $p$-norm function $f \in L^p(\mathbf{T})$. find accurate for $p\geq 2$ $0<s\leq p$, thus significantly improving results from \cite{KALAJ.TAMS} where it is considered $s=2$ $1<p<\infty$. Inte...

Treatment methods for breast cancer are not specific and each one has its own drawbacks. For this reason, scientists are seeking ways in which specifically affect cancer cells. Photothermal therapy is a method that uses near-infrared (NIR) laser energy to create sufficient heat to destroy cancer cells. In this study, the photothermal effect of gold nanorods (GNRs) was investigated for breast ca...

Introduction: This study aimed to compare operation time, intraoperative bleeding and postoperative pain between cold dissection tonsillectomy and harmonic scalpel tonsillectomy.  Materials and Methods: In this single-blinded clinical trial, 32 patients aged 14–48 were enrolled. Each patient randomly underwent tonsillectomy using the harmonic scalpel on one side and cold dissection on the other...

accurate calculation of reliability index is very important for the reliability analysis of structures. in some limit state functions with nonlinear characteristic and several local optimum design points, the computational reliability methods may not appropriately determine the failure probability, and iterative reliability approaches may be converged to local optimum design points. in this pap...
