Cell phone technology and second language acquisition: an action research experiment

This action research study explored the possibility of engaging Japanese university learners of English as a Foreign Language (EFL) to use their cell phones to communicate in the target language. One hundred and two students participated in a pre and post-test survey to collect their opinions about producing cell phone-based audio-visual resources. In addition, evidence collected from 50 participants' cell phone videos reports on their verbal performances. The outcome of this experiment provides an example for integrating cell phones as part of the language curriculum and it reveals that students gained some benefits from using this technology.

Case of Pott’s Disease in a 17-Year-Old Patient in the Dominican Republic

Pott’s disease, or spinal tuberculosis, is caused by the pathogen Mycobacterium tuberculosis. Although tuberculosis is endemic in developing countries, such as Dominican Republic, Pott’s disease is rarely seen, only representing 1% of the total cases. Due to its low incidence, this could be easily misdiagnosed. We report a case of a 17-year-old male with a history of pleural effusion that presented with severe back pain. Several imaging studies reported an aggressive paravertebral neoplasia at the thoracic levels. A surgical biopsy was performed, and the procedure revealed bone fragmentation, which prompted the need to rule out Pott’s disease per current recommendations. Biopsy and subsequent positive QuantiFERON-TB Gold test confirmed spinal tuberculosis.
Uncovering Behavioral Strategies: Likelihood-Based Experimental Data Mining

Economists and psychologists have recently been developing new theories of decision making under uncertainty that can accommodate the observed violations of standard statistical decision theoretic axioms by experimental subjects. We propose a procedure which finds a collection of decision rules that best explain the behavior of experimental subjects. The procedure is a combination of maximum likelihood estimation of the rules together with an implicit classification of subjects to the various rules, and a penalty for having too many rules. We prove that our procedure yields consistent estimates (as the number of tasks per subject and the number of subjects go to infinity) of the number of rules being used, the rules themselves, and the proportion of our population using each of the rules. We apply our procedure to data on probabilistic updating by subjects in four different universities. We get remarkably robust results which show that the most important rules used by the subjects are Bayes rule, representativeness rule (ignoring the prior), and conservatism (over-weighting the prior). In our procedure, the subjects are allowed to make errors, and our estimated error rate is typically 20%.
Peripartum cardiomyopathy: An analysis of clinical profiles and outcomes from a tertiary care centre in southern India

Peripartum cardiomyopathy is a syndrome of maternal heart failure with decreased left ventricular ejection fraction affecting maternal and fetal well-being. We analysed clinical profiles and outcomes in women with peripartum cardiomyopathy enrolled retrospectively from a tertiary care centre in southern India (1 January 2008–31 December 2014). The incidence of peripartum cardiomyopathy was one case per 1541 live births. Fifty-four women with a mean age of 25.5 years and mean gestational age of 35.4 weeks were recruited; 35 were primigravidae. Maternal and fetal deaths occurred in 9.3% and 24.1% of subjects, respectively. Mild-to-moderate maternal anaemia (80–110 g/L) was associated with fetal mortality (p = 0.02). Reduced left ventricular ejection fraction (<30%, p = 0.04) and cardiogenic shock (p = 0.01) were significantly associated with adverse maternal outcomes. Forty per cent of women were followed up after 24.2 ± 17.7 months, and in these women a significant increase in left ventricular ejection fraction was seen (mean 16.4%, p < 0.01); all were asymptomatic. Peripartum cardiomyopathy with poor left ventricular ejection fraction and shock is associated with adverse maternal outcomes, while non-severe maternal anaemia predisposes to adverse fetal outcomes. Significant left ventricular ejection fraction recovery occurred on follow-up.

Validation of automated arrhythmia detection for Holter ECG

This paper describes a fast and very effective feature extraction technique for detection and discrimination of QRS on a microprocessor-based Holter ECG analysis system. The technique converts long term (up to 24 hours) recorded ECG into a positive waveform by signal preprocessing. Three characteristic factors, the duration, the areas, and the original slope of the positive waveform are detected when the onset and end points of each pulse have been detected by dynamic threshold detection. The prominent feature is extracted from a product of these three factors. It is used to identify normal beats and arrhythmias. This method has been examined using 47 different patients' ECG signals on a MIT/BIH database. The accuracy of QRS detection was 99.3% in validation. The identification sensitivity of PVC beats was 95.2% with 14 different arrhythmia patients. The method has also been implemented on a microprocessor based Holter ECG analysis system. A record of the MIT database recorded ECG can be completely analyzed within 30 second for reporting the heart rate variations, heart beat classifications and arrhythmia analysis.
Semantic Web Service Process Mediation in WSMO:Current Solutions and Open Issues

Process mediation plays an important role in ensuring successful interaction between a provider and a service requestor. Therefore process mediation could be conceptualized as a 'middleware' that coordinates t he interaction between web services. The Semantic Web Service promises automation in discovery, selection and composition but is still facing serious challenges in resolving mismatches where the Web service interaction takes place. For this paper, the WSMO, a Semantic Web Services framework is chosen and the current process mediation approaches that have adopted this framework are analyzed. The findings enable the identification of some open issues and p rocess mediation elements. These identified factors can be further explored to support automatic communication mismatches in the generic Web Services.
The Efficiency of WhatsApp in Teleconsultation of Finger Vascularity in Hand Surgery

Abstract Background Teleconsultation over the smartphone is now widely used in modern medicine in the management of burns, flap cover, upper extremity trauma, and in the assessment of the feasibility of reimplantation in amputated fingers. The development of the WhatsApp application has enhanced the smartphone's efficiency remarkably to transmit images in clinical and academic settings with its failsafe and encrypted technology. In hand surgery, a teleconsultation technology must communicate details of finger vascularity effectively. However, there is a paucity of evidence on the functionality of these modern teleconsultation technologies in Hand Surgery. Here, the authors have estimated the efficiency of the WhatsApp teleconsultation in the assessment of finger vascularity. Materials and Methods In two phases, the authors transmitted clinical photographs of vascular and avascular fingers to experienced hand surgeons over the WhatsApp and asked them to assess the finger vascularity. The efficiency of the WhatsApp teleconsultation in assessing the details of finger vascularity was estimated from their responses. Results Despite 81.06% of the hand surgeons rating the vascular fingers on the transmitted photographs correctly, only 44.95% detected the avascular digits accurately; that is, 55.05% of the surgeons failed to diagnose the avascularity of fingers. This suggests serious implications in a clinical setting. The intra- and the inter-rater reliability values were 0.232 and 0.6086 (with 95% confidence interval), respectively, which indicated poor reliability of the WhatsApp teleconsultation regarding the assessment of finger vascularity. Conclusion The authors, therefore, conclude that WhatsApp is inadequate in teleconsultation given the value of vascularity details of the fingers in making a diagnosis in hand surgery.
Formal Verification of Distributed Programs using Session Types and Coq

This thesis investigates one possible way of proving functional correctness of distributed programs by integrating Session Types and Separation Logic. We introduce a language that has Session Type style typing judgements inside its Hoare triples and Separation Logic predicates inside its Session Type protocols. The language – which builds on an existing Java-like language built by Bengtson et al. [3] – is implemented in Coq, which has also been used to prove properties and theorems of the language semantics. The extended language has the new send, recv and start primitives with which programs with multiple processes that communicate using message-passing governed by Session Type protocols can be constructed. Using Separation Logic predicates instead of types to describe the transferred data, receivers are allowed to assume properties proven by the sending party. As a case-study, we introduce a version of distributed merge sort implemented in our language and show its correctness using decorated programs on paper. The results show that our language has the ability to reason about the functional correctness of recursive, distributed programs using Hoare-triples and Separation Logic predicates in a way that is similar to how non-distributed programs are verified.
Probiotic awareness among general dentists in Chennai

Aim: To assess the awareness of probiotic among general dentists in Chennai. Materials and Methods: A cross sectional survey was conducted among 100 general dental practitioners through a questionnaire about the awareness of probiotics and its effects and usage. Result: All the participants were aware of probiotics but the awareness about its constituents, benefits and usage was considerably less. Though majority of the participants were aware of the benefits of probiotics almost one third of them did not prescribe. Conclusion: Though beneficial, lack of adequate knowledge regarding probiotics limited its usage among general dentists in Chennai
A growing fear

The purpose of the present study was to investigate the prevalence of nomophobia (the fear of being out of mobile phone contact) among young adults in Turkey. The Nomophobia Questionnaire (NMP-Q) was administered to 537 Turkish college students. The results revealed 42.6% of young adults had nomophobia, and their greatest fears were related to communication and information access. The study also found that gender and the duration of smartphone ownership had an effect on young adults’ nomophobic behaviors, whereas age and the duration of mobile phone ownership had no effect. Based on these results, implications, limitations, and further studies were discussed.

Myasthenia gravis (MG) is an autoimmune disease caused by autoantibodies to the acetylcholine receptors of the neuromuscular junction characterized by weakness and abnormal fatigability of the muscles. Therefore, the diagnosis of MG depends on the recognition of this distinctive pattern of fatigable weakness. Previous studies presented the diagnostic efficacy of saccadic eye movements in patients with ocular MG. We here in report 2 patients of ocular MG showing the fatigue effects during repetitive sustained smooth pursuit, and the effects of the administration of edrophonium on myasthenic smooth pursuit. Changes in smooth pursuits reflecting peripheral and secondary central mechanisms were demonstrated. Res Vestib Sci 2019;18(2):54-58
Defense trees for economic evaluation of security investments

In this paper we present a mixed qualitative and quantitative approach for evaluation of information technology (IT) security investments. For this purpose, we model security scenarios by using defense trees, an extension of attack trees with attack countermeasures and we use economic quantitative indexes for computing the defender's return on security investment and the attacker's return on attack. We show how our approach can be used to evaluate effectiveness and economic profitability of countermeasures as well as their deterrent effect on attackers, thus providing decision makers with a useful tool for performing better evaluation of IT security investments during the risk management process.
CDS-1548 induces apoptosis in HeLa cells by activating caspase 3

Cervical cancer continues to be a threat to female health globally. In the present study, the potential anticancer activity of 2-[2-hydroxyl-1-(4-methoxy phenyl) ethyl]-3-(4-benzyloxy phenyl) isoindolin-1-one (CDS-1548), was evaluated in HeLa cells. CDS-1548 is an organic small-molecule compound characterized by two chiral centers, with the nuclear parent 1H-isoindolin-1-one. CDS-1548 administration significantly elevated the transcriptional activity of p53 and its downstream target genes in a dose-dependent manner. Additionally, CDS-1548 treatment increased the expression levels of p53 and mouse double minute 2 homolog, as well as inducing apoptosis in HeLa cells. Furthermore, CDS-1548 treatment downregulated the expression of B-cell lymphoma 2, upregulated Bcl-2 homologous antagonist killer, promoted the release of cytochrome c from mitochondria to cytoplasm, and activated the production of caspase 3 and 9. Collectively, these results suggested that CDS-1548 inhibited HeLa cell proliferation by promoting G2/M cell cycle phase arrest and inducting of mitochondria-mediated apoptosis.
Mining Frequent Sub-hypergraph in an Uncertain Hypergraph for Knowledge Transfer

The knowledge transfer learning can generalize across domains where the types of objects and variables are different. Previous studies ignored connectivity and creativity of domain knowledge. Thus, these studies just transfer knowledge from a source domain to a target domain that not effectively use the knowledge from other domains. We proposed a method, called Multi-domain second order knowledge integration (MSKI), for integrating to address this problem. We hybridize and create new knowledge, which is formalized into an uncertain hypergraph. Then, we proposed a method to mine frequent sub-hypergraph from the uncertain hypergraph (MFS-UHG). The frequent sub-hypergraphs are pivot knowledge, which has to be transferred with high priority. We embed the pivot knowledge in the progress of MLN structure learning. The experimental evaluation on four domain datasets shows that the MSKI outperforms state-of-the-art MLN-based transfer learning.
A distributed heuristic solution using arbitration for the MMMKP

The Multiple-Choice Multi-Dimension Multi Knapsack Problem (MMMKP) is the distributed version of Multiple-Choice Multi-Dimension Knapsack Problem (MMKP), a variant of the 0--1 classic Knapsack Problem. Algorithms for finding the exact solution of MMKP as well as MMMKP are not suitable for application in real time decision-making applications. This paper presents a new heuristic algorithm, Arbitrated Heuristic (A-HEU) for solving MMMKP. A-HEU finds the solution with a few messages at the cost of reduced optimality than that of I-HEU, which is a centralized algorithm. We also discuss practical uses of MMMKP such as distributed Video on Demand service.
A virtual network service for integrated-services internetworks

Integrated-services internetworks are usually defined as those internetworks that are designed to carry a variety of traffic types and to satisfy the main requirements of each type of traffic. In this paper, we argue that the services needed to satisfy such requirements are not the only ones those internetworks will have to offer in order to become a true basis for human society in the next century, they must be able to reproduce the most important features of networkless society, one of which is the provision of support to a variety of groups. We show how a service that will allow any interested user to create a virtual network for a group on top of any integrated-services internetwork can be designed. We call such a virtual network a "supranet".
Effects of different doses of tamoxifen on the sperm parameters and chromatin quality in mice: An experimental model

Abstract Background Tamoxifen (TX) is widely used for the treatment of male factor and idiopathic infertility. It has been shown that TX induces sperm production and so improves male fertility. Objective This study evaluated the effects of different doses of TX on the sperm parameters and chromatin quality in mice. Materials and Methods In this research, 24 male NMRI mice were divided into three groups including group A: control animal receiving vehicle; group B: the group receiving basal diet and TX 0.4 mg/kg/day; and group C: the group receiving basal diet and TX 0.6 mg/kg/day for 35 days. Thereafter, epididymal spermatozoa were analyzed for standard parameters and nuclear chromatin quality using Aniline Blue (AB) and Toluidine Blue (TB) staining. Results The results indicated that although the TX did not affect the sperm count, motility, and viability parameters, it could elevate the percentage of sperm cells with abnormal morphology and abnormal chromatin at both doses. In addition, in comparison with the control mice, a significant elevation was observed in spermatozoa with residual histones (assessed by AB staining) at high doses of TX. Conclusion Our experimental data in mice suggested that the use of TX for treating male infertility might increase the rates of spermatozoa with abnormal chromatin in a dose-dependent manner.
Dissociating Alzheimer’S Disease from Amnestic Mild Cognitive Impairment using Time-Frequency Based Eeg Neurometrics

Alzheimer’s Disease (AD), already the most common cause of dementia, is a rapidly escalating worldwide health concern thanks to increasing life expectancies and aging populations. This work explores the utility of using magnitude (ERSP), phase angle (ITPC), and cross-frequency coupling (PAC) indices derived from electroencephalogram (EEG) recording using spectral decomposition as unique biomarkers of AD and amnestic mild cognitive impairment (aMCI), respectively. The experimental protocol was a visual oddball discrimination task conducted during a brief (approximately 20 minute) recording session. Participants were 60 older adults from an outpatient memory clinic diagnosed with either aMCI (n=29; M=73.0; SD=9.32) or AD (n=31; M=78.29; SD=8.28) according to NIA-AA criteria. Results indicate that ITPC values differ significantly between AD and MCI groups. Findings contribute to a growing body of literature seeking to document illness-related abnormalities in time-frequency EEG signatures that may serve as reliable indicators of the pathophysiological processes underlying the cognitive deficits observed in AD and aMCI-afflicted populations.
The effects of pulse pressure on left atrium andleft ventricle geometry in hypertensive patients

Objectives: An increased pulse pressure (PP) suggests aortic stiffening. New evidence suggests that (PP) is more sensitive measure of cardiac risk than other indexes of blood pressure. We aim to study the effect of pulse pressure in hypertensive patients on left atrial and left ventricle diameters (LAD, LVD), left ventricle geometry [wall thickness (WT), left ventricle mass (LVM), regional wall thickness (RWT)] and the effects of age and sex on the PP. Methods: Echocardiography study of LAD, LVD, left ventricle end diastolic diameter (LVEDD), aortic root diameter (ARD), ratios and left ventricle geometry was performed on 92 patients (61 female & 31 male). A correlation analysis between these variables and pulse pressure was done. Patients were grouped into high PP >60 mmHg and normal PP <59 mmHg and chi-square test was applied. Results: We found strong positive correlation between age and PP (p value =0.00), positive correlation of PP with WT, LVM and SBP (p value < 0.05) and positive correlation of LVM to LAD, LVD, RWT, LAD/ARD, LAD/LVEDD and the age (p value <0.05). Conclusion: The PP which increased by age is the most important BP measurement (compared to SBP and DBP) that directly affects LV geometry mainly WT & LVM.
Research on One Secure Solution for Multiple Factor Ambiguous Pattern Recognition System

Ambiguous pattern recognition is a very important technology in the field of science including engineering application nowadays, it uses methods of fuzzy mathematics enabling the computer to recognize and judge the objective things. But, the research on ambiguous pattern recognition system rarely involves the field of security, while in fact both the participant of the pattern recognition and the database need to protect their privacy. This paper mainly introduces the secure multi-party computation into the field of ambiguous pattern recognition, raises a new solution for the secure multi factor ambiguous pattern recognition system under the half honest model, and proves the validity and security of the protocol.
