hiatus is a situation in which there is no consonant between the nuclei of two adjacent syllables. it occurs when the left syllable lacks a coda while the right one lacks an onset. hiatus occurs in underlying representation or at a level between underlying and phonetic representations. its occurrence is expected in every language, but its resolution is obligatory in languages which require syll...

objective: globozoospermia is a rare syndrome with an incidence of less than 0.1% among infertile men. researchers have recently identified a large deletion, about 200 kbp, encompassing the whole length of dpy19l2 or mutations in spata16 and pick1 genes associated with globozoospermia. the aim of this study was to analyze the dpy19l2 gene deletion using polymerase chain reaction technique for t...

Previous correlational research shows that childhood adversity is associated with earlier age of reproduction in humans and other species. Such studies, however, cannot show that stressful conditions cause earlier reproduction. Using the cold-pressor task, we built on previous work to test the idea that acute stress influences human reproductive and marital ideals, and that individual stress re...

The common causes of 18p deletion syndrome are spontaneous errors in the chromosomal structure in the early stages of human embryonic development. In this study, a 29-year-old girl was introduced with the features of deletion of chromosome 18. In addition, GTG banding karyotype revealed that this case had a deletion involving the short arm of chromosome 18. In comparison with the usual phenotyp...

Fingerspelling recognition is one of the last skills acquired, due to the complex nature of fingerspelling and a lack of display technology that is sufficiently natural for recognition practice. This paper describes a corpus-based study utilizing an n-gram extension to ELAN to gain a deeper understanding of deletion and coarticulation in fingerspelling. The analysis shows that coarticulation an...
