The aim of this experiment is to assess the effects of the linguistic status of timbre on pitch processing in the brainstem. Brainstem frequency following responses were evoked by the Mandarin high-rising lexical tone superimposed on a native vowel quality ([i]), nonnative vowel quality ([œ]), and iterated rippled noise (nonspeech). Results revealed that voice fundamental frequency magnitudes w...

Surprisingly little is known about the neural mechanism of cough. Although slow and fast adapting stretch receptors in the air passages have been hypothesized to trigger cough, stimuli that activate these receptors do not induce cough. Recently, a new receptor type responsive to touch and acid—stimuli that also evoke cough—was identified in guinea pigs. Mazzone et al. have further characterized...

The question whether or not vowel quality can be maintained at F0 of the sounds exceeding statistical F1 of „normal“ speech is still a matter of debate. The present study investigates the perception of long Cantonese vowels /i, y, œ, a, ɔ, u/, spoken and sung in (C)V and (C)V:S context by a well-known female Cantonese Opera singer in the range of F0 of c. 560–860Hz. 172 high-pitched syllables o...

The stiffness in some systems of nonlinear differential equations is shown to be characterized by single stiff equations of the form y' = g'(x) + \\y g(x)\. The stability and accuracy of numerical approximations to the solution v = g(x), obtained using implicit one-step integration methods, are studied. An S-stability property is introduced for this problem, generalizing the concept of /4-stabi...

There appear to be two ways read Art. 60.7 in the current Shenzhen Code (Turland & al. Regnum. Veg. 159. 2018). The key question is where diacritical signs are found. was discussion (23–27 Aug 2021 at https://taxacom.markmail.org/) on name Eflugelia after Erik Flügel, some authors having come conclusion that sign needs “to suppressed with necessary transcription of letters so modified”, i.e. a ...

Belladonna alkaloids have been prized for centuries for their mind-altering qualities (Shader & Greenblatt, 1971), and the toxic state resulting from poisoning with these alkaloids was well recognised. Christison (1845) described the leading symptoms as “¿ dryness in the throat, then delirium with dilated pupils and after wards coma―.The delirium he noted to be “¿ generally extravagant an...

THE swallowing of foreignbodies is more prevalent in prisonsthan in mental hospitals. Is it that there is something in the prison environment which causes some prisoners to swallow foreign bodies, or should the clue be sought for in the personalities of the swallowers? A few prisonswallowers are insane, the great majority are not. Most of the swallowers I have seen were psychopathic personaliti...

THOUGH electro-convulsive therapy (E.C.T.) is one of our most useful treat ments, its mode of action is still largely unknown, and this ignorance is preventing us from making it more successful and more widely applicable. Among its possible modes of action is the possibility of its having some “¿ activating― action on the basal, and more particularly on the hypothalamic, structures. Such ac...
