Intracranial lipomas are rare, usually do not have clinical expression and are located more frequently in the corpus callosum. Other locations include the spinal cord, midbrain tectum, superior vermis, tuber cinereum, infundibulum and more rarely cerebellopontine angle, hypothalamus, superior medullary velum and insula. We report the case of a lipoma of the left inferior colliculus which was a ...

This paper presents a method for determining the vocaltract spectrum from the positions of xed points on the articulatory organs. The method is based on the search of a database comprised of pairs of articulatory and acoustic data representing the direct relationship between the articulator position and vocal-tract spectrum. To compile the database, the electro-magnetic articulograph (EMA) syst...

We have constructed models /i/ and /u/ of the vocal tract from the glottis to the velum with the pyriform fossa and the larynx, and have analyzed by finite element method. Sound pressure distributions in XY cross-sections at 500Hz, the first resonant frequencies, and 2500Hz are shown. The barycentric coordinates of real part of the sound intensity and of sound particle velocity in each XY cross...

An acoustic study is carried out to see whether the phenomenon of pharyngalization and/or velarizsation is confined to the emphatic consonant and the adjacent vowels or it extends over the whole word in Arabic. Measurements in Hz of F1 & F2 of front unrounded vowels in monosyllabic, bisyllabic and trisyllabic words in ISA having emphatic vs. non-emphatic consonants were made. They showed signif...

Abstract Objective To evaluate the feasibility of systematic observer training in drug-induced sedation endoscopy (DISE) interpretation. Methods Fifty DISE videos were randomly selected from a group 200 cohort patients with OSA and/or snoring. The assessed blindly and independently using modified VOTE classification by an expert two novice observers starting their training. A approach was initi...

Thioautotrophic endosymbionts in the Domain Bacteria mediate key sulfur transformations in marine reducing environments. However, the molecular pathways underlying symbiont metabolism and the extent to which these pathways are expressed in situ are poorly characterized for almost all symbioses. This is largely due to the difficulty of culturing symbionts apart from their hosts. Here, we use pyr...

Jonathan Keane It is widely assumed in the articulatory phonology literature that when an articulator is not active (unspecified in the gestural score) it assumes a neutral state. One example of this is that the velum, when not active, assumes a closed position; only when it is actively opened does it deviate from that position. is assumption makes predictions about speech that seem to be fairl...

Speech quality is an essential output in assessing the success of a palatoplasty. The goal palatoplasty not merely to create simple anatomical closure palate, but also adequate velopharyngeal mechanism for normal speech outcome and prevent abnormal maxillofacial development after surgery. aim this study find out difference between post-cleft palate patients without cleft palate. An analytical r...
