The results of the research showed that students studying in the Faculty of Theology had low levels of smartphone addiction, male students had higher levels of smartphone addiction compared to female students, the use of social media via smartphones increased the risk of addiction, and that students with a higher average daily smartphone usage also had higher levels of addiction.
Word Sense Disambiguation in Hindi Language Using Score Based Modified Lesk Algorithm

Hindi is the widely used spoken language in the Indian subcontinent, and is used by more than 260 million Indians citizens. Indian governments has many digital initiatives to serve Indian citizen better, hence Hindi language becomes one of the important languages to serve Indian citizen. The Government initiatives are like smart city, Hospital Services, Common Service Centers, Digital Payment Ecosystem, Pensioners Scheme, Digital Locker and many more. These all initiative are served using mobile and web based applications, which citizens can access easily instead of visiting various government departments. To serve the large Hindi speaking population, it is necessary to handle the ambiguous words which have multiple connotations in any natural language processing task. In this paper, word sense disambiguation for Hindi language is proposed. Proposed method makes use of Lesk algorithm to disambiguate the Hindi words. Novel scoring method is used to assign a sense score to each token of the Hindi sentence. The sense score is calculated based on the gloss, hypernym, hyponym and synonym of the combinations of different sense of tokens. Hindi WordNet database created by CFILT, IIT Bombay is used in the proposed system. The proposed algorithm takes a natural language (NL) sentence in Hindi (Devanagari script) and process the sentence according to the score based approach modeled on the basic Lesk algorithm with the help of Hindi WordNet designed by CFILT IIT Bombay. The solution provided in this paper can be used vividly in various web based applications like Query-Response Systems, Question-Answer Systems, Sentiment analysis, Recommendation systems etc.
Distinct spectral response in 
M
-edge magnetic circular dichroism

Experimental investigations of ultrafast magnetization dynamics increasingly employ resonant magnetic spectroscopy in the ultraviolet spectral range. Besides allowing to disentangle the element-specific transient response of functional magnetic systems, these techniques also promise to access attosecond to few-femtosecond dynamics of spin excitations. Here, we report on a systematic study of transient magnetic circular dichroism (MCD) on the transition metals Fe, Co and Ni as well as on a FeNi and GdFe alloy and reveal a delayed onset between the electronic and magnetic response. Supported by \textit{ab-initio} calculations, we attribute our observation to a transient energy shift of the absorption and MCD spectra at the corresponding elemental resonances due to non-equilibrium changes of electron occupations.

Contextualize Knowledge Bases with Transformer for End-to-end Task-Oriented Dialogue Systems

Incorporating knowledge bases (KB) into end-to-end task-oriented dialogue systems is challenging, since it requires to properly represent the entity of KB, which is associated with its KB context and dialogue context. The existing works represent the entity with only perceiving a part of its KB context, which can lead to the less effective representation due to the information loss, and adversely favor KB reasoning and response generation. To tackle this issue, we explore to fully contextualize the entity representation by dynamically perceiving all the relevant entities and dialogue history. To achieve this, we propose a COntext-aware Memory Enhanced Transformer framework (COMET), which treats the KB as a sequence and leverages a novel Memory Mask to enforce the entity to only focus on its relevant entities and dialogue history, while avoiding the distraction from the irrelevant entities. Through extensive experiments, we show that our COMET framework can achieve superior performance over the state of the arts.
Characteristics of motor dysfunction in longstanding HIV.

BACKGROUND Cognitive dysfunction in HIV has decreased, but milder forms of HIV-associated neurocognitive disorders (HAND) persist along with motor dysfunction. The HIV Motor Scale (HMS) is a validated tool which captures motor abnormalities on routine neurologic examination, and which is associated with cognitive impairment in HIV. In this study, we applied a modified HMS (MHMS) to a nationwide cohort of people with longstanding HIV to characterize and understand the factors contributing to motor dysfunction. METHODS The National NeuroAIDS Tissue Consortium (NNTC) is a nationwide longitudinal cohort study. Participants undergo regular assessments including neurological examination, neuropsychological testing and immunovirologic data collection. Data from examinations were used to calculate the MHMS score which was then correlated with history of AIDS-related CNS disorders (ARCD; e.g. prior CNS opportunistic infection), cerebrovascular disease (CVD) and HIV-associated neurocognitive disorder (HAND). RESULTS Sixty-nine percent of participants showed an abnormality on the MHMS, with 27% classified as severe. Results did not vary based on demographic or immunologic variables. The most common abnormalities seen were gait (54%) followed by coordination (39%) and strength (25%), and these commonly co-occurred. CVD (p=0.02), history of ARCD (p=0.001), and HAND (p=0.001) were all associated with higher (i.e. worse) HMS in univariate analyses; CVD and ARCD persisted in multivariate analyses. CVD was also marginally associated with symptomatic HAND. CONCLUSIONS Complex motor dysfunction remains common in HIV and is associated with CVD, ARCD and to a lesser extent HAND. Future studies are needed to understand the longitudinal trajectory of HIV-associated motor dysfunction, its neural substrates and impact on quality of life.
Robust output feedback regulation for infinite-dimensional systems

In this paper, a robust output regulation problem is considered for general infinite-dimensional systems. More precisely, for the design of the regulator, the controlled output y(t) and the reference signal yr(t) are assumed to be available. One mode of the designed regulator is driven by the tracking error ey(t), and is used for the reference signal tracking and disturbance rejection, while another mode driven by y(t) is used to address the plant stabilization. In particular, simpler and sufficient conditions are provided to injection and feedback gains. The robustness is achieved based on Internal Model Principle and verified for non-destabilizing system with model uncertainties and simultaneous satisfaction of G−conditions is guaranteed. An uncertain hyperbolic PDE system is used to demonstrate the paper results. keyword: Infinite-dimensional systems, robust output regulation, model uncertainty, output feedback.
Characteristic Performance of Guard Electrode in LA–SF–ICP– MS for Multi-Element Quantification

The performance characteristics of the use of a guard electrode in laser ablation–sector field–inductively coupled plasma–mass spectrometry for multiple element quantification were investigated in this study. The guard electrode (GE) shapes and increases the ion density of the plasma prior to injection into the sample cone. The results illustrate that the GE shifts the ionization zone back to the sample cone which requires a larger carrier gas flow rate for compensation. The signal intensity of 55 elements was enhanced by a factor of 3–20 with the use of GE (hereafter denoted “GE-on mode”) compared to that without using GE (hereafter denoted “GE-off mode”), however, at the cost of higher oxide and doubly charged ion yields. The enhancement capability was negatively correlated with elemental mass number. Elements with low mass number showed a large sensitivity improvement. The limits of detections were not improved in the GE-on mode due to the enhanced background intensity. Ion transmission efficiency was improved by a factor of 3–20 and the linear relationship between mass number and transmission efficiency in GE-off mode is changed to the quadratic relationship in GE-on mode. Mass discrimination may be limited to lower mass elements with no further increase at >100 a.m.u. The ion profile in ICP illustrated that the GE increases the ion density of the plasma, which is probably related to the reduced ion kinetic energy distribution. The analyses of seven MPI-DING and one USGS glass reference materials show that the analytical precision in the GE-on mode is improved by a factor of 2–4 in comparison to the GE-off mode, and accuracy is almost identical in both modes.
Analysis of the Influence of Measurement Circuit Asymmetries on Three-Phase CM/DM Conducted EMI Separation

Electromagnetic interference (EMI) conducted emissions (CE) are of increasing concern in power electronics due to the high switching frequency and fast switching speeds of the latest generation of wide-bandgap semiconductors. The decomposition of the total conducted EMI noise into its common-mode (CM) and differential-mode (DM) part by means of a CM/DM noise separator is a useful tool that allows for a systematic EMI filter design. Carefully designed realizations achieve a CM rejection ratio and DM rejection ratio of <inline-formula><tex-math notation="LaTeX">${50}\,$</tex-math></inline-formula>dB at <inline-formula><tex-math notation="LaTeX">${30}\,$</tex-math></inline-formula>MHz. However, a very high-performance CM/DM noise separator is not sufficient. It is theoretically analyzed and experimentally proven that asymmetries in the EMI test setup result in an unwanted conversion between CM and DM EMI noise, and therefore significantly influence the CM/DM EMI separation. In particular, three main influences are identified: the line impedance stabilization network (LISN), the connection cables between LISN and the equipment under test (EUT), and the converter EMI filter. The unwanted noise conversion is pronounced for frequencies in the MHz range, where parasitic resonances occur. Experimental results show a CM-to-DM conversion of up to <inline-formula><tex-math notation="LaTeX">${-30}\,$</tex-math></inline-formula>dB at <inline-formula><tex-math notation="LaTeX">${30}\,$</tex-math></inline-formula>MHz (a degradation by <inline-formula><tex-math notation="LaTeX">${20}\,$</tex-math></inline-formula>dB or a factor of 10 compared to a high-performance separator alone) considering a connection cable length mismatch of roughly <inline-formula><tex-math notation="LaTeX">${5}\,$</tex-math></inline-formula>cm. Values as high as <inline-formula><tex-math notation="LaTeX">${-21\,}$</tex-math></inline-formula>dB result when standard commercial LISNs are used for the measurement. The impact of asymmetries in the EMI filter is most severe, and clearly limits the EMI noise splitting at high frequencies. A high-performance noise separator can, however, be used to investigate such filter asymmetries (component tolerances and/or layout), and therefore helps to improve the filter design process and facilitates the modeling of EMI noise sources.

Synthesis of NaYF4:Yb, Er up-conversion luminophore from nitrate flux

The behavior of nanoparticle ensembles was studied using of NaRF4 hexagonal phases. The evolution of particles in the process of rapid and productive synthesis from flux as a result of a chemical reaction was investigated. A low-temperature synthesis process in the medium of sodium nitrate was used. Synthesis of the samples of up-conversion phosphor NaY0.78Yb0. 2Er0.02F4 was performed from rare-earth nitrates at 350 – 430 ◦C for 15 – 500 min. NaF was used as the fluorinating agent. Powder X-ray phase analysis and scanning electron microscopy revealed a rapid transformation of the cubic alpha modification into a hexagonal phase, followed by the transformation of nanoparticles into hexagonal prisms of micron sizes. The up-conversion luminescence energy yield increased as the reaction time increased.
Do financial restricted companies use the cash flow for investment or for cash holdings?

The present paper aims to verify whether the most financially restricted companies use their cash flow for investment or for cash holdings. To this end, the cash flow sensitivity of investment as well as the cash flow sensitivity of cash for Brazilian publicly traded companies through the Threshold method is tested, given its classification in restricted and unrestricted companies. In this context, the models of Fazzari, Hubbard and Petersen (1984) and Almeida, Campello and Weisbach (2004) were applied, using as structural breaks the Dividends Paid, Total Assets, Z-score and KZ-index. The result of the analysis was not clear in relation to which behavior is predominant in Brazilian companies. Using the Total Asset as a Threshold, the model that was most representative was the one referring to investments in capital goods. But, considering the Z-score as a Threshold, the most representative model indicates that companies use more Cash Flow results for cash holdings. Dividends and KZ-index were not significant in the analysis.
The Clinical Impact of Body Mass Index on Breast Cancer in Korea: A Nationwide Population-Based Cohort Study

Purpose: Although increasing body mass index (BMI) is regarded as a potential risk factor for breast cancer (BC) in postmenopausal women, research on premenopausal women has produced conflicting results. We investigated the association between BMI and BC according to menopausal status in Korean. Methods: We analyzed clinical data from 186,835 women aged 20 years or older between 2003 and 2008 using a sample cohort from the national database in Korea. We identified women newly diagnosed with BC and estimated the risk of BC according to BMI (kg/m). Subjects were categorized into five groups according to World Health Organization recommendations for Asians: underweight, <18.5 kg/m; normal weight, 18.5–22.9 kg/m; overweight, 23.0–24.9 kg/m; obese class I, 25.0–29.9 kg/m; and obese class II, ≥30.0 kg/m. Results: 1,372 women in the cohort were newly diagnosed with BC. A positive relationship between BMI and BC was detected and the hazard ratio in each group compared with the normal weight group was 0.57 (95% CI, 0.42–0.78), 1.27 (1.11–1.45), 1.25 (1.09–1.44), and 1.28 (0.95–1.73), respectively. BMI was determined to be an important risk factor for BC in postmenopausal women (p for trend was 0.015). We failed to find a significant correlation between BMI and BC in premenopausal women. Conclusion: BMI is positively associated with BC in postmenopausal Korean women.
Factors influencing low intension detection rate in a non-invasive EEG-based brain computer interface system

Motor imagery (MI) responses extracted from the brain in the form of EEG signals have been widely utilized for intention detection in brain computer interface (BCI) systems. However, due to the non-linearity and the non-stationarity of EEG signals, BCI systems suffer from low MI prediction rate with both known and unknown influncing factors. This paper investigates the impact of visual stimulus, feature dimensions and artifacts on MI task detection rate, towards improving MI prediction rate. Three EEG datasets were utilized to facilitate the investigation. Three filters (band-pass, notch and common average reference) and the independent component analysis (ICA) were applied on each datasets, to eliminate the impact of artifact. Three sets of features where extracted from artifact free ICA components, from which more relevant features were selected. Moreover, the selected feature subsets were incorporated into three classifiers, NB, Regression Tree and K-NN to predict four MI and hybrid tasks. K-NN classifier outperformed the other two classifies in each dataset. The highest classification accuracy is obtained in hybrid task EEG dataset. Moreover, accurately predicted EEG classes were applied to a robotic arm control.
Effects of bran from sorghum grains containing different classes and levels of bioactive compounds in colon carcinogenesis

Effects of Bran from Sorghum Grains Containing Different Classes and Levels of Bioactive Compounds in Colon Carcinogenesis. (December 2008) Jayme Beth Lewis, B.S., Texas A&M University Chair of Advisory Committee: Dr. Nancy D. Turner In order to test the dietary effects of bioactive compounds present in whole grains, we decided to observe the effect of varying types of sorghum bran on colon cancer promotion. We used 40 rats consuming diets containing 6% fiber from either cellulose or bran from white (contains phenolic acids), brown (contains tannins), or black (contains anthocyanins) sorghum (n=10). Diets were fed for 10 wk, during which two azoxymethane (AOM) injections (15 mg/kg BW) were administered in wk 3 and 4. We observed that the total number of aberrant crypts (AC) and high multiplicity aberrant crypt foci (HMACF) were lower in rats consuming black (p < 0.04) and brown (p < 0.006) sorghum diets when compared to the cellulose diet, and that these decreases were an inverse function of diet antioxidant activity (ABTS). These observations led us to evaluate the effect of these diets on endogenous enzymatic activities (superoxide dismutase, SOD; catalase, CAT; and glutathione peroxidase, GPx), redox status as measured by reduced and oxidized glutathione, and cell cycle processes, proliferation and apoptosis, in the rat colon. Total SOD activity was higher (p < 0.04) in rats consuming black sorghum when compared to all other diets. A similar, but not
Effect of seed priming on seed quality of resultant seed in Kabuli chickpea (Cicer arietinum L.) varieties

A laboratory experiment was carried out at Seed Quality and Research Laboratory, Seed Unit (National Seed Project), University of Agricultural Sciences, Dharwad during rabi of 2016-17 and 2017-18 to study the effect of seed priming on seed quality parameters of resultant seed in kabuli chickpea varieties. Seed quality parameters were significantly influenced among varieties and priming treatments. BG1105 (V1) recorded significantly higher seed quality parameters as compared to MNK-1 (V2), While seed priming with Sprint (Mancozeb 50% + Carbendazim 25% WS) @ 2 g per kg of seed (T9) recorded significantly higher seed quality parameters as compared to other treatments and control (T1) during 2016-17 and 2017-18 and pooled data. Therefore, seed priming with sprint (Mancozeb 50% + Carbendazim 25% WS) @ 2 g per kg of seed (T9) can be used in order to enhance the seed quality of kabuli chickpea varieties.
MECHANICAL AND THERMAL PRE-TREATMENT OF BIOMASS FOR THE THERMOCHEMICAL CONVERSION

This paper presents investigations on some residual biomass kinds and analysis mechanical and thermal pre-treatment approaches to improve thermochemical conversion process. Four different biomass samples were dried, mechanical grinding and sieving to decrease the moisture content and particle size to increase conversion efficiency. Samples had an initial moisture content of >10%, after drying all samples have a similar humidity (≈5%). A grinding time of 5-10 minutes has proven to be sufficient to obtain a high fraction of particle size less than 1mm, more effective for thermochemical conversion. This pre-treatment has improved the yield, the smaller particles lead to a higher gas fraction.
