How should one syllabify medial homorganic nasal plus stop (-VNCV-) clusters in Hindi such as those in [] ‘tall’ and [] ‘pebble’? A variety of principles have been proposed by phonologists, the three most common ones being the ‘legality’ principle, ‘maximize onset’ principle, and the ‘sonority sequencing’ principle. In this paper we will attempt to show that all -VNCVclusters do not ...

All spoken languages encode syllables and constrain their internal structure. But whether these restrictions concern the design of the language system, broadly, or speech, specifically, remains unknown. To address this question, here, we gauge the structure of signed syllables in American Sign Language (ASL). Like spoken languages, signed syllables must exhibit a single sonority/energy peak (i....

this study presents an overview of the different strategies that persian learners of english employ to deal with initial clusters. while vowel epenthesis appears to be the most widespread repair strategy to conform such clusters to persian phonotactics, the location of the epenthetic vowel varies. in this paper, we investigate two approaches that seek to explain the epenthetic site. the first o...

Syllable contact pairs cross-linguistically tend to have a falling sonority slope, a constraint which is called the Syllable Contact Law (SCL). In this study, the phonotactics of syllable contacts in 4202 CVC.CVC words of Persian lexicon is investigated. The consonants of Persian were divided into five sonority categories and the frequency of all possible sonority slopes is computed both in lex...

New gene formation by polyploidy has been an ongoing process during the evolution of various eukaryotes that has contributed greatly to the large number of genes in their genomes. After duplication, some genes that are retained can acquire new functions or expression patterns, or subdivide their functions or expression patterns between duplicates. Here, we show that SHORT SUSPENSOR (SSP) and Br...

barley belongs to the poaceae which is the largest monocotyledon family. plastid single-copy gene acetyl-coa carboxylase (accase) is the first step in the biosynthesis of fatty acids and therefore, it is used to study the phylogenetic relationships, evolutionary and systematic of grasses. in this study, for the first time, phylogenetic relationship of eight species of hordeum genus from iran in...

Colonization of oral tissues by Streptococcus sanguis may be influenced by a mucin-like salivary glycoprotein (SAG) through a calcium-dependent interaction with a specific bacterial receptor. We report the nucleotide and deduced amino acid sequence of the S. sanguis receptor (SSP-5) and show that this protein may bind sialic acid residues of SAG. The SSP-5 protein contains three unique structur...

Majorcan (and Balearic) Catalan dialects lack an overt inflectional morpheme for first person singular present indicative verb forms. Many of these Majorcan Catalan (MC) verbs end with the consonants of the verb root with no further inflectional vowel (represented by the morphs /u/, /o/, /e/ or /i/ in other dialects of Catalan). This divergent morphological structure is illustrated in (1) from ...

Staphylococcus saprophyticus surface-associated protein (Ssp) was the first surface protein described for this organism. Ssp-positive strains display a fuzzy layer of surface-associated material in electron micrographs, whereas Ssp-negative strains appear to be smooth. The physiologic function of Ssp, however, has remained elusive. To clone the associated gene, we determined the N-terminal sequ...
