Objective Vowels are the center of syllables while formant structures are one of the most important acoustic characteristics of speech sounds that help in their articulatory and perceptual aspects. Formants represent the shape and size of the vocal tract. There exist trivial differences between the vocal tracts of different people due to which the formant structures of a vowel in one person are different from another person. Towards the end of the 20 th century, advances in acoustic science and

These voice acoustical characteristics analyses lead to better assessment of the voices. Effective treatment of speech disorders depends on accurate diagnosis by the speech-language pathologist. The relationship between the first three formants is the main component of perceptual categorization by the listener. Therefore, the aim of the current study is to determine and compare Persian vowel frequency of first, second and third formants in bilingual adults. Materials & Methods A cross-sectional study was performed on 50 participants (25 males and 25 females) aged 18 to 24 years. Bilingual students from Tabriz University of Medical Sciences were selected by an easy and non randomized sampling method, where the average of the first, second and the third formant frequencies for each of the six Persian vowels were taken into consideration. Data collection involved a demographic questionnaire (age, gender, bilingualism, and diseases related to the speechbreathing mechanism), the consent form, a computer equipped with PRATT Software and one sound recorder set.

GA-Novo: De Novo Peptide Sequencing via Tandem Mass Spectrometry using Genetic Algorithm [article]

Samaneh Azari, Bing Xue, Mengjie Zhang, Lifeng Peng
2019 arXiv   pre-print
Proteomics is the large-scale analysis of the proteins. The common method for identifying proteins and characterising their amino acid sequences is to digest the proteins into peptides, analyse the peptides using mass spectrometry and assign the resulting tandem mass spectra (MS/MS) to peptides using database search tools. However, database search algorithms are highly dependent on a reference protein database and they cannot identify peptides and proteins not included in the database.
more » ... , de novo sequencing algorithms are developed to overcome the problem by directly reconstructing the peptide sequence of an MS/MS spectrum without using any protein database. Current de novo sequencing algorithms often fail to construct the completely matched sequences, and produce partial matches. In this study, we propose a genetic algorithm based method, GA-Novo, to solve the complex optimisation task of de novo peptide sequencing, aiming at constructing full length sequences. Given an MS/MS spectrum, GA-Novo optimises the amino acid sequences to best fit the input spectrum. On the testing dataset, GA-Novo outperforms PEAKS, the most commonly used software for this task, by constructing 8% higher number of fully matched peptide sequences, and 4% higher recall at partially matched sequences.

Improving the Results of De novo Peptide Identification via Tandem Mass Spectrometry Using a Genetic Programming-based Scoring Function for Re-ranking Peptide-Spectrum Matches [article]

Samaneh Azari, Bing Xue, Mengjie Zhang, Lifeng Peng
2019 arXiv   pre-print
De novo peptide sequencing algorithms have been widely used in proteomics to analyse tandem mass spectra (MS/MS) and assign them to peptides, but quality-control methods to evaluate the confidence of de novo peptide sequencing are lagging behind. A fundamental part of a quality-control method is the scoring function used to evaluate the quality of peptide-spectrum matches (PSMs). Here, we propose a genetic programming (GP) based method, called GP-PSM, to learn a PSM scoring function for

Important characteristics about goodness of the matches are extracted from the learning set and incorporated into the GP scoring functions. We compare GP-PSM with two methods including Support Vector Regression (SVR) and Random Forest (RF). The GP method along with RF and SVR, each is used for post-processing the results of peptide identification by PEAKS, a commonly used de novo sequencing method. The results show that GP-PSM outperforms RF and SVR and discriminates accurately between correct and incorrect PSMs. It correctly assigns peptides to 10% more spectra on an evaluation dataset containing 120 MS/MS spectra and decreases the false positive rate (FPR) of peptide identification.

2016 Journal of Health Research in Community. Autumn   unpublished
Introduction and purpose: The release of chlorinated organic compounds (COCs) is accounted as a danger for public health and environment due to their harmful effects such as carcinogenicity, toxicity, and flammability. Trichlorethylene (TCE) is one of the most famous COCs, which is commonly used as a solvent for dry-cleaning and industrial degreasing and contaminates soil and groundwater. Thus, it is considered as a possible carcinogenic compound (class B2) for humans. Therefore, this study was

Methods: Iron nanoparticles were prepared through the Ferric Chloride revival method by sodium borohydride. The properties of nanoparticles were determined using scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and vibrating sample magnetometer. In addition, the effect of pH, concentration of trichloroethylene, iron nano-particle dosage, and contact time were studied on TCE removal efficiency. Box Behnken model was used to investigate the interaction of these variables. Analysis of variance was considered as the statistical method for analysis of responses. Results: Results showed that the degradation efficiency was equal to 91.23% in optimal conditions (pH=3, nanoparticles dose= 0.63 g/l, TCE concentration= 11 mg/l, and contact time= 86 min). The results of kinetic studies revealed that TCE degradation by nZVI follows first-order kinetic model. Conclusion: It is conclude that zero-valent iron nanoparticles have a good efficiency in the degradation of TCE. On the other hand, separation of these nanoparticles is simple due to its magnetism properties, which can improve the use of these nanoparticles.
