Continuance intention of using e- book among higher education students

This paper investigates determinant of continuance intention to use e-book among higher education students. The determinants used in this paper are adopted from Technology Acceptance Model (TAM) and Expectancy Disconfirmation Theory (EDT). The quantitative study employed random sampling where the email invitation which contained a hypertext link of the survey page, enables the participants to access to the survey hosted in Google Drive. Out of 760 sample size, a total of 650 responses were gathered with 509 valid responses used for analysis. The data were analysed to test the relationship between determinants of continuance intention to use e-book among higher education students. The finding demonstrates that determinant of continuance intention to use ebook are based on Satisfaction, while Satisfaction is strongly determined by Perceived Ease of Use and Confirmation of using e-book. Internet self-efficacy is reported to have strong effect on Satisfaction through Perceived Ease of Use, while Perceived Quality affects Satisfaction of using ebook through Confirmation. In general findings from this study are beneficial for libraries in that determinants of continuance intention of using e-books could also be used in selecting and evaluating e-books features before subscription. Additionally e-book vendors could use these findings to improve and enhance features of their e-books services.
Functional role of cyanidin-3-O-glucoside in osteogenesis: A pilot study based on RNA-seq analysis

Cyanidin-3-O-glucoside (C3G) is the most widely distributed anthocyanin and it can reportedly reduce the risk of osteoporosis, but the molecular mechanism by which C3G promotes bone formation is poorly understood. In the current study, RNA sequencing (RNA-seq) was used to investigate the mechanism of action of C3G in osteogenesis. MC3T3-E1 mouse osteoblasts were divided into a C3G (100 μmol/L)-treated group and a vehicle-treated control group, and differentially expressed genes (DEGs) in groups were evaluated via RNA-seq analysis. The functions of the DEGs were evaluated by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses, and the genes were validated by quantitative real-time PCR. The RNA-seq analysis identified 34 genes that were upregulated in C3G-treated cells compared to vehicle-treated cells, and 17 that were downregulated GO and KEGG pathway analyses indicated that these genes were highly enriched in functions related to lysosomes and glycolipid biosynthesis, among others. The differential expression of ATPase H+-transporting V0 subunit C (Atp6v0c), chemokine (C-X3-C motif) ligand 1 (Cx3cl1), and lymphocyte antigen 6 complex, locus A (Ly6a) genes was validated by quantitative real-time-PCR. Because these genes have been previously implicated in osteoporosis, they are potential target genes of C3G action in MC3T3-E1 cells. These results provide molecular level evidence for the therapeutic potential of C3G in the treatment of osteoporosis and other disorders of bone metabolism.
Nonspecific Facial Expression Recognition via the Sparse Representation and Weighted

On the person-independent facial expression recognition, the utilization rate of the facial expression texture is not high. Facing with the problem of the person-independent face, this paper proposes a method about facial expression recognition based on the improved weighted local binary pattern(LBP) and sparse representation. In order to use the local texture information of the facial organs effectively, first it uses the improved weighted LBP operator to extracting the local texture feature, the extracted features to construct the training samples, and classified via the sparse representation last. Experimental results show a better performance on the JAFFE and CK database.
Capturing the holistic profile of high performance Olympic weightlifting development

Recent expertise development studies have used retrospective recall methods to explore developmental biographies and/or practice histories of current or past athletes. This methodological approach limits the generalizability and trustworthiness of findings. As such, a gap exists for research exploring key multidisciplinary features in athlete development using prospective longitudinal research designs. The present research aimed to holistically model the development of talent in Olympic Weightlifting using such a design. We observed the holistic profiles of 29 junior weightlifting athletes longitudinally over a 10-month period, and subsequently classified six of the 23 athletes as high performing based on their performances in competitions up to 12 months following the study. This holistic profile was based on a framework of expertise development themes: (1) demographics and family sport participation, (2) anthropometrics and physiological factors, (3) psychosocial profiling, (4) sport participation history, and (5) weightlifting specific practice activities. A summary model was produced which selected a critical set of nine features that classified group membership with 91% average accuracy. Odds ratio calculations uncovered discriminating features in the holistic profiles of performance groups, from which empirically derived logical statements could inform the description of high-performance attainment.

TDOA detection algorithm in interference location for satellite systems

In order to enhance the performance of interference location for satellite systems based on TDOA measurement,a new TDOA parameter estimation method is presented based on wavelet transform and the Naiman-Pearson principle.By the use of the characteristic of the wavelet de-noising,TDOA estimation is convergent to the true value with a high probability in the low signal-to-noise ratio(SNR) environment and the performance of interference location for satellite systems is improved.By choosing an appropriate wavelet function to process the wavelet transform as weighted calculation,the processing burden can be reduced greatly during wavelet transform.The simulation results illustrate the reliability and effectiveness of this new TDOA estimation method.
Content-centered method for search engine optimization

Value of online business has grown to over one trillion USD. This thesis is about search engine optimization, which focus is to increase search engine rankings. Search engine optimization is an important branch of online marketing because the first page of search engine results is generating majority of the search traffic. Current articles about search engine optimization and Google are indicating that with the proper use of quality content, there is potential to improve search engine rankings. However, the existing search engine optimization literature is not noticing content at a sufficient level. To decrease that difference, the content-centered method for search engine optimization is constructed, and content in search engine optimization is studied. This content-centered method consists of three search engine optimization tactics: 1) content, 2) keywords, and 3) links. Two propositions were used for testing these tactics in a real business environment and results are suggesting that the content-centered method is improving search engine rankings. Search engine optimization is constantly changing because Google is adjusting its search algorithm regularly. Still, some long-term trends can be recognized. Google has said that content is growing its importance as a ranking factor in the future. The contentcentered method is taking advance of this new trend in search engine optimization to be relevant for years to come.
A Morpho-Semantic Analysis of Verbs as Lexical Categories

A principal aspect of a language analysis is the investigation of the structure of words and their organization into the grammar of a language. A language satisfies the communicative needs of the society and people using it when certain rules are observed in the production of linguistic expressions. Lexical category is a unit of classification of words in the grammar of a language and serves to portray the unique configuration properties of certain words and word classes. This paper surveys an aspect of word categorization in Ẹdo language (lexical category) with special focus on the properties of the verb as a member of this class. Illustrations will be provided in the paper to justify first of all the dichotomy between different classes of words in the language (lexical vs functional) and the place of the verb in the category of words known as ‘lexical’. The findings of the paper will show that the verb possesses rich morphological, syntactic and semantic features that justify its inclusion in the class of lexical class of words.
From spontaneous rhythmic engagement to joint drumming: A gradual development of flexible coordination at approximately 24 months of age

Humans have a flexible and accurate ability to coordinate their movement in time with external rhythms. However, it remains unclear when and how, during their development, human children acquire the ability to adjust tempo and control the timing of their movement toward others. A previous study suggested that such self-regulation of coordination develops at around 18 and 30 months after birth. In this study, we investigated the performance of 24-month-old children and compared their data with those of 18- and 30-month-olds provided in our previous study. In the joint-drumming task, each child was enticed to drum under four conditions [partner: mother or robot; speed: 400 or 600 ms inter-stimulus-interval (ISI)]. The most pivotal test condition was the 600 ms ISI speed condition (slower than children’s spontaneous motor tempo in these age groups). We found that from the age of 24 months, children try to slow down their drumming tempo toward the 600 ms ISI speed condition, regardless of the drumming partner. On the other hand, significant timing control toward the onset of the 600 ms ISI condition was observed from the age of 30 months. This implies that both motor and cognitive mechanisms are required for flexible tempo adjustment and accurate synchronization and that these develop gradually among 18-, 24-, and 30-month-olds.
Decreased anterograde transport coupled with sustained retrograde transport contributes to reduced axonal mitochondrial density in tauopathy neurons

Mitochondria are essential organelle required for neuronal homeostasis. Mitochondria supply ATP and buffer calcium at synaptic terminals. However, the complex structural geometry of neurons poses a unique challenge in transporting mitochondria to synaptic terminals. Kinesin motors supply mitochondria to the axonal compartments, while cytoplasmic dynein is required for retrograde transport. Despite the importance of presynaptic mitochondria, how and whether axonal mitochondrial transport and distribution are altered in tauopathy neurons remain poorly studied. In the current study, we have shown that anterograde transport of mitochondria is reduced in P301L neurons, while there is no change in the retrograde transport. Consistently, axonal mitochondrial abundance is reduced in P301L neurons. We further studied the possible role of two opposing motor proteins on mitochondrial transport and found that mitochondrial association of kinesin is decreased significantly in P301L cells. Interestingly, fitting our experimental data into mathematical equations suggested a possible rise in dynein activity to maintain retrograde flux in P301L cells. Our data indicate that decreased kinesin-mediated transport coupled with sustained retrograde transport might reduce axonal mitochondria in tauopathy neurons, thus contributing to the synaptic deficits in Alzheimer’s disease (AD) and other tauopathies.
Antioxidant and antiradical activities depend on adrenal tumor type

The aim of the study was to assess the total antioxidant/oxidant status in the plasma and urine of patients with adrenal tumors. The study group consisted of 60 patients (31 women and 29 men) with adrenal masses, classified into three subgroups: non-functional incidentaloma, pheochromocytoma and Cushing’s/Conn’s adenoma. The number of patients was set a priori based on our previous experiment (α = 0.05, test power = 0.9). Antioxidant activity (Total Antioxidant Capacity (TAC), Total Oxidant Status (TOS), Oxidative Stress Index (OSI)) and antiradical activity (Radical-Scavenging Activity Assay (DPPH), Ferric-Reducing Antioxidant Power (FRAP)) were measured using colorimetric methods. FRAP level was decreased in plasma and urine incidentaloma (p<0.0001), pheochromocytoma (p<0.0001) and Cushing’s/Conn’s adenoma (p<0.0001), while DPPH antiradical activity only in plasma of patients with adrenal masses (p<0.0001). Plasma TAC was increased in incidentaloma patients (p=0.0192), whereas in pheochromocytoma group (p=0.0343) was decreased. Plasma and urine TOS (p<0.0001) and OSI (p<0.01) were significantly higher in patients with adrenal tumors. In pheochromocytoma patients, plasma and urine TAC (p=0.001; p=0.002), as well as plasma plasma DPPH (p=0.007) and urine FRAP (p=0.017) correlated positively with normethanephrine. We are the first who showed reduced radical scavenging capacity in the plasma/urine of patients with adrenal masses. Nevertheless, plasma TAC was significantly higher in the incidentaloma group compared to controls. Therefore, plasma and urinary antioxidant and antiradical activities depend on the presence of the tumor. Lower levels of TAC, DPPH and FRAP clearly indicate a reduced ability to scavenge free radicals and thus a lack of effective protection against oxidative stress in patients with adrenal tumors. Both plasma and urine redox biomarkers can be used to assess systemic antioxidant status in adrenal tumor patients.
AST-to-ALT ratio in the first trimester and the risk of gestational diabetes mellitus

Background Aspartate aminotransferase-to-alanine transaminase ratio (AST/ALT) has been reported affect the risk of type 2 diabetes (T2DM), but it is uncertain if it has relationship with gestational diabetes mellitus (GDM). Objectives Our study aimed to investigate the association between AST/ALT ratio in the first trimester and the risk of subsequent development of GDM. Method This prospective cohort study enrolling 870 pregnant women, 204 pregnant women with missing data or liver diseases were excluded, 666 pregnant women were included in this study containing 94 GDM women. Blood samples were collected in the first trimester. Univariate analysis and multivariate logistic regression were used to evaluate the association between AST/ALT and GDM. Nomogram was established based on the results of multivariate logistic analysis. Receiver Operating Characteristic (ROC) curves and calibration curves were used to evaluate the predictive ability of this nomogram model for GDM. Decision curve analysis (DCA) was used to examine the clinical net benefit of predictive model. Results AST/ALT ratio (RR:0.228; 95% CI:0.107-0.488) was associated with lower risk of GDM after adjusting for confounding factors. Indicators used in nomogram including AST/ALT, maternal age, preBMI, waist circumference, glucose, triglycerides, high density lipoprotein cholesterol and parity. The area under the ROC curve (AUC) value of this predictive model was 0.778, 95% CI (0.724, 0.832). Calibration curves for GDM probabilities showed acceptable agreement between nomogram predictions and observations. The DCA curve demonstrated a good positive net benefit in the predictive model. Conclusions The early AST/ALT level of pregnant women negatively correlated with the risk of GDM. The nomogram including AST/ALT at early pregnancy shows good predictive ability for the occurrence of GDM.
AM1 calculations of reaction field effects on the tautomeric equilibria of nucleic acid pyrimidine and purine bases and their 1-methyl analogs

Semiempirical AM1 quantum-chemical calculations of the principal tautomers of cytosine, thymine, uracil, 1-methylcytosine, 1-methylthymine, 1-methyluracil, adenine, and guanine were carried out for the isolated molecules, and for the same molecules in a polarizable dielectric medium with the relative permittivity of water, using the self-consistent reaction field method. In almost all cases, the same tautomer is predicted as most stable regardless of the method used and environment applied. However, the calculations imply significant quantitative differences in the relative stabilities of the tautomers in different media, which need to be taken account of in the nucleic acid base pairing/mispairing probability estimations based on quantum-chemical data

An Improved Multi-class Support Vector Machine for Hyperspectral Remote Sensing Imagery Classification

Support Vector Machine (SVM) is applied in the research on hyperspectral remote sensing image classification. Decision Boundary Feature Extraction (DBFE) algorithm is adopted as dimension reduction for hyperspectral image data. Radial Basis Function (RBF) is used as SVM kernel function. The chaotic optimization search technique was introduced into the Particle Swarm Optimization (PSO) algorithm. Its main idea is, within the basic PSO framework, to overcome disadvantages of low convergent speed and easily falling into local minimum by chaotic optimization search with predetermined number of steps for the best particle among a population. The improved PSO algorithm is proposed to automatically determine SVM model parameters, and the PSO based SVM (PSO-SVM) model was constructed. Experimental results of 220 bands AVIRIS hyperspectral data indicate that PSO-SVM algorithm, we proposed in this paper, can improve the overall classification accuracy about 8.8%, as compared to the standard SVM with Leave One Out(LOO) based grid search strategy. The proposed algorithm is very efficient for small samples and unbalanced remote sensing data cmassification.
Autonomous facial expression recognition using the facial action coding system

The South African Sign Language research group at the University of the Western Cape is in the process of creating a fully-fledged machine translation system to automatically translate between South African Sign Language and English. A major component of the system is the ability to accurately recognise facial expressions, which are used to convey emphasis, tone and mood within South African Sign Language sentences. Traditionally, facial expression recognition research has taken one of two paths: either recognising whole facial expressions of which there are six i.e. anger, disgust, fear, happiness, sadness, surprise, as well as the neutral expression; or recognising the fundamental components of facial expressions as defined by the Facial Action Coding System in the form of Action Units. Action Units are directly related to the motion of specific muscles in the face, combinations of which are used to form any facial expression. This research investigates enhanced recognition of whole facial expressions by means of a hybrid approach that combines traditional whole facial expression recognition with Action Unit recognition to achieve an enhanced classification approach.
Variación diatópica, discursiva y fonética de /s/ codal en el habla de profesionales chilenos

espanolEl siguiente trabajo de investigacion se enmarca en la sociolinguistica cuantitativa y busca dar cuenta del fenomeno de la variacion de /s/ en posicion codal en una muestra de profesionales chilenos. Ademas de describir la variacion del fonema /s/ en posicion codal, este estudio busca determinar la variacion de /s/ codal en relacion con 3 variables: ciudad, modalidad discursiva (lectura en voz alta y entrevista semiespontanea) y contexto fonico (interior y final de palabra). En virtud de esto, se selecciono una muestra de 323 informantes de 8 ciudades capitales chilenas, y se realizo un analisis auditivo clasico de n= 3.264 realizaciones de /s/ codal. Los resultados del analisis descriptivo de los datos y de la prueba de χ2 de Pearson indican que las variables modalidad discursiva y contexto fonico tienen un efecto en la variacion de /s/ codal en los datos de la muestra; por su parte, el analisis en relacion con la variable ciudad no fue concluyente. EnglishThe present article falls within the framework of a quantitative and descriptive sociolinguistics perspective and it aims to describe the phenomenon of coda /s/ variation in a sample of college-educated subjects, speakers of Chilean Spanish. Moreover, this research aims to describe the variation of coda /s/ in Chilean Spanish regarding three variables: city of origin of the informant, discourse modality (reading aloud and semispontaneous interview) and phonetic context (wordinterior and word-final). In order to do so, a sample of 32 informants from 8 different Chilean regional capital cities was selected from FONDECYT4 Project N.1120886. The sample was analyzed by means of an auditory classical analysis, which considered n=3.264 tokens of coda /s/. The results from the descriptive analysis and from a Pearson’s chi-squared test show that the variables “discourse modality” and “phonic context” have an effect on the variation of coda /s/ in the sampled data. On the other hand, the analysis regarding the diatopic variable and its effect on coda /s/ variation was not conclusive.
