Music teacher’s reports suggest that the respiratory function and laryngeal control in wind instruments, stimulate muscular tension of the involved anatomical structure. However, the physiology and acoustics of the larynx during trumpet playing has seldom been studied. Therefore, the current paper describes the laryngeal articulation during trumpet performance with biomedical signals and audito...

We consider the problem of computing certain parameterized minimum volume outer ellipsoidal (MVOE) approximation of the Minkowski sum of a finite number of ellipsoids. We clarify connections among several parameterizations available in the literature, obtain novel analysis results regarding the conditions of optimality, and based on the same, propose two new algorithms for computing the paramet...

This study investigated whether there were individual differences in within-category sensitivity to the voicing contrast and, if so, whether these differences were related to listeners‟ differential sensitivity to different acoustic cues. To do this, we conducted two speech perception experiments with English-speaking adults: visual analogue scaling (VAS) and anticipatory eye movement (AEM). St...

A characterization of Blaschke addition as a map between origin-symmetric convex bodies is established. This results from a new characterization of Minkowski addition as a map between origin-symmetric zonoids, combined with the use of Lévy-Prokhorov metrics. A full set of examples is provided that show the results are in a sense the best possible.

We derive a Brunn-Minkowski-type inequality regarding the volume of the Minkowski sum of degenerate sets, namely, line sets. Let A 1 : : : A n be one dimensional sets of unit length, and v

To determine the relative position of any two surfaces in a system, one approach is to use operations (Minkowski sum and intersection) on sets of constraints. These constraints are made compliant with half-spaces of n  where each set of half-spaces defines an operand polyhedron. These operands are generally unbounded due to the inclusion of degrees of invariance for surfaces and degrees of fre...

Five taxa viz, Agaricus altipes, A. cupreobrunneus, A. placomyces, A. porphyrocephalus, and A. urinascens var. urinascens are reported as new records for Iran. Details of taxonomical important features are also presented herewith. New localities in the west and north-west of the country are reported as habitats of Agaricus speciesin Iran.  

Basic helix-loop-helix (bHLH) transcription factors are involved in many abiotic stress responses as well as flavonol and anthocyanin biosynthesis. In grapes (Vitis vinifera L.), flavonols including anthocyanins and condensed tannins are most abundant in the skins of the berries. Flavonols are important phytochemicals for viticulture and enology, but grape bHLH genes have rarely been examined. ...
