SRJA: A research on optimizing top-k join queries based on spark

With the explosive growth of RDF data, the traditional centralized environment is increasingly unable to adapt to this huge data query processing requirements, especially the top-k query. This paper designs and implements the original storage scheme of RDF data based on HBase, and presents two top-k query algorithms: STA (Spark Threshold Algorithm) and SRJA (Spark Rank Join Algorithm) which are under Massive RDF Data Query Processing Framework which Based on HBase-based storage system and Spark-based Parallel Computing System. The STA (Spark Threshold Algorithm) is to reduce the RDF data connection during the operation of the operation. The SRJA (Spark Rank Join Algorithm) is proposed to reduce the sort-related operations of the intermediate data and it is the optimization of. Experimental results show that the SRJA algorithm is superior to the STA algorithm and the traditional top-k algorithm, and has strong applicability.
Health outcomes of unpaid care workers in low-income and middle-income countries: a protocol for a systematic review

Introduction The literature on health outcomes of unpaid care work has included studies coming from high-income countries, and has reported gender inequalities that make caregiving women more vulnerable to physical and mental health problems. The impact of unpaid care work on the health of those living in low-income and middle-income countries, where women’s autonomy is more limited, is unknown. Methods and analysis We will conduct a systematic review of observational studies on health outcomes according to unpaid caregiving status and sex of people living in low-income and middle-income countries. Cumulative Index to Nursing and Allied Health Literature, PubMed and Scientific Electronic Library Online Citation Index will be searched for reports in English or Spanish with published results from inception to 1 June 2017. We expect the studies to have recruited individuals in low-income and middle-income countries, including exposed and non-exposed groups to participation in unpaid care to members if their households or community reporting either physical and/or mental health problems, self-reported health-related quality of life, self-care skills/behaviours or use of any healthcare services in the participants. Data extraction, the assessment of risk of bias and confounding, and qualitative synthesis will be carried out by two independent reviewers with the assistance of a third party. Dissemination Results are expected to be published in peer-reviewed journals from the field of health and gender, or health and inequality. PROSPERO registration number CRD42017071785.
Migraine with Aura and Right-to-Left Shunt on Transcranial Doppler: A Case-Control Study

Right-to-left shunt (RLS), usually due to patent foramen ovale, is a well-established risk factor for ischemic stroke in young patients, while the role of migraine as an independent factor is still debated. We evaluated 44 patients suffering from migraine with aura, and compared them with 73 patients younger than 50 with focal cerebral ischemia, and 50 controls, asymptomatic for cerebrovascular disease, and without a history of migraine. All the subjects underwent bilateral transcranial Doppler with injection of contrast medium in an antecubital vein. The test was performed during normal ventilation and during Valsalva maneuver, recording both the middle cerebral arteries and the basilar artery. Criteria for diagnosing RLS was the presence of at least 3 microbubbles within 15 s from injection. Eighteen out of 44 migraine patients (41%) showed RLS, as opposed to 8 of 50 controls (16%) (p < 0.005). Twenty-six out of 73 patients with cerebral ischemia had RLS (35%). We conclude that the prevalence of RLS in patients with migraine with aura is significantly higher than in normal controls, and is similar to the prevalence of RLS in young patients with stroke. These findings could be helpful in understanding the relationship between migraine and stroke.
Effects of continuous positive airway pressure on energy balance regulation: a systematic review

Obesity is both a cause and a possible consequence of obstructive sleep apnoea (OSA), as OSA seems to affect parameters involved in energy balance regulation, including food intake, hormonal regulation of hunger/satiety, energy metabolism and physical activity. It is known that weight loss improves OSA, yet it remains unclear why continuous positive airway pressure (CPAP) often results in weight gain. The goal of this systematic review is to explore if and how CPAP affects the behaviour and/or metabolism involved in regulating energy balance. CPAP appears to correct for a hormonal profile characterised by abnormally high leptin and ghrelin levels in OSA, by reducing the circulating levels of each. This is expected to reduce excess food intake. However, reliable measures of food intake are lacking, and not yet sufficient to make conclusions. Although studies are limited and inconsistent, CPAP may alter energy metabolism, with reports of reductions in resting metabolic rate or sleeping metabolic rate. CPAP appears to not have an appreciable effect on altering physical activity levels. More work is needed to characterise how CPAP affects energy balance regulation. It is clear that promoting CPAP in conjunction with other weight loss approaches should be used to encourage optimal outcomes in OSA patients. CPAP in sleep apnoea patients affects some aspects of energy balance regulation, which can affect body weight http://ow.ly/6ATZ303KXRv
A Study of Asynchronous Mobile-Enabled SMS Text Psychotherapy.

BACKGROUND Many obstacles to obtaining psychotherapy continue to diminish its reach despite its documented positive effects. Using short message service (SMS) texting and Web platforms to enable licensed psychotherapists to deliver therapy directly to the lived context of the client is one possible solution. INTRODUCTION Employing a feasibility study design, this pilot trial further evaluated the external validity for treatment outcomes of text therapy and extended findings to include mobile-enabled text platforms. MATERIALS AND METHODS Adults seeking text therapy treatment for a variety of disorders were recruited from a text therapy service (N = 57). Clinical outcomes were measured using the General Health Questionnaire-12 (GHQ-12) through 15 weeks of treatment. A process variable, the therapeutic alliance, was measured with the Working Alliance Inventory. Treatment acceptability was assessed with ratings of satisfaction for several aspects of the treatment, including affordability, effectiveness, convenience, wait times to receiving treatment, and cost-effectiveness. RESULTS Results indicate evidence for the effectiveness of the intervention (GHQ-12, Cohen's d = 1.3). Twenty-five (46%) participants experienced clinically significant symptom remission. Therapeutic alliance scores were lower than those found in traditional treatment settings, but still predicted symptom improvement (R2 = 0.299). High levels of satisfaction with text therapy were reported on dimensions of affordability, convenience, and effectiveness. Cost-effectiveness analyses suggest that text therapy is 42.2% the cost of traditional services and offers much reduced wait times. CONCLUSION Mobile-enabled asynchronous text therapy with a licensed therapist is an acceptable and clinically beneficial medium for individuals with various diagnoses and histories of psychological distress.
A Typological Analysis of Behavioral Profiles of Sexually Abused Children

A cluster analysis is used to explore differential outcomes in 123 French Canadian children reporting sexual abuse contrasted with 123 control children. Mothers' reports of behavioral problems on the Child Behavior Checklist, abuse-related variables, personal factors, and family characteristics are used as potential variables discriminating clusters. Results reveal four clusters: (a) anxiety constellation group refers to children displaying behavior problems on a subset of scales, (b) the severe distress group refers to children showing a broader array of behavior problems, (c) victims of less severe sexual abuse (SA) group consists of children disclosing mostly extrafamilial SA, and (d) resilient children refers to children who, while disclosing severe abuse, rely less on avoidance coping. Findings underscore the need to go beyond abuse-related variables to orient treatment for children disclosing sexual abuse and for tailoring interventions to distinct subgroups.
Health status of older adults living in the community in Japan: Recent changes and significance in the super‐aged society

As of 2017, the total Japanese population was 126.7 million, which included 35 million who were aged ≥65 years (27.6%) and 17.3 million aged ≥75 years (13.7%). From now, the old‐old aged ≥75 years will increase rapidly in Japan compared with the young‐old aged 65–74 years. The characteristics of the old‐old include deterioration of activities of daily living (ADL) functions and an increase of chronic diseases, which are unavoidable consequences of advanced age. In the present review article, secular changes of the health status and functional capacity of older people living in communities are described based on representative longitudinal studies on aging in Japan. The author also discusses the importance and implication of two major strategies related to health promotion, and prevention of both lifestyle‐related diseases and long‐term care dependence in the super‐aged society. Among the old‐old people, prevention of long‐term care dependence becomes a much higher priority than disease prevention. In regard to evidence‐based prevention of long‐term care dependence, various geriatric syndromes, such as undernutrition, falling, incontinence and decline of cognitive function, are the major targets for prevention. Many randomized controlled trials on the prevention of geriatric syndromes have been carried out in Japan, targeting high‐risk older people living in the community, and have attained many excellent achievements so far. Finally, the author introduces a new index of competence for older people (the Japan Science and Technology Agency Index of Competence), which can accurately measure high‐level competence and higher functioning needed to execute the activities of more sophisticated living of today and in the future.

Decoupling of the Occipitotemporal Cortex and the Brain’s Default-Mode Network in Dyslexia and a Role for the Cingulate Cortex in Good Readers: A Brain Imaging Study of Brazilian Children

ABSTRACT The goal of the present study was to investigate intrinsic and reading-related brain function associated with dyslexia and typical readers in monolingual Brazilian children. Two fMRI studies were carried out: a resting-state and a word-reading study. The results show (a) underconnectivity between the occipitotemporal region (visual word form area) and the brain’s default-mode network in dyslexic readers and (b) more activation of the anterior cingulate cortex for typical readers relative to dyslexic readers. The findings provide evidence for brain connectivity and function differences in an underrepresented population in fMRI studies of dyslexia; the results suggest atypical intrinsic function, and differences in directed attention processes in dyslexia.
Risks of Intra-Abdominal Nonshunt Surgery in Cirrhotics

We have reviewed the risks of various nonshunt intra-abdominal operations in cirrhotic patients. Most of these studies are retrospective reviews with limitations. Among various risk stratifications in cirrhosis, Child-Pugh classification is sufficiently informative. Elective surgery can be done safely in patients with Child’s A or B class. Operations in Child’s C patients and emergent surgery carry formidably high mortality. Limiting the extent of surgery, controlling ascites, correcting coagulation abnormality and malnutrition and aggressively treating infection, might reduce mortality. Laparoscopic cholecystectomy and endoscopic sphincterotomy in cirrhotics seem to be promising in reducing mortality and morbidity.
Task assignment to distributed teams aided by a hybrid methodology of verbal decision analysis

An increasingly common practice in large software development companies is to distribute tasks among geographically dispersed teams. This practice can bring many benefits, such as gains in terms of time and cost, but many are the challenges. One of the major challenges regards the method of assigning tasks to remote teams. This method involves knowing, classifying and ordering the factors that drive the assignment of tasks in a distributed scenario. This is a typical scenario for decision-making based on multiple criteria. Verbal decision analysis (VDA) is a multi-criteria framework to decision-making. This study presents a hybrid methodology structured on methods of VDA for classification ORdinal CLASSification (ORCLASS) and ordering (ZAPROS III-i) of factors that drive task assignment to distributed teams in software development projects. Tasks were grouped according to their type, i.e. requirements, architecture, implementation, and testing.
Genetic Relationships among Japanese, Northern Han, Hui, Uygur, Kazakh, Greek, Saudi Arabian, and Italian Populations Based on Allelic Frequencies at Four VNTR (D1S80, D4S43, COL2A1, D17S5) and One STR (ACTBP2) Loci

The genetic polymorphism at four variable number of tandem repeats (D1S80, D4S43, COL2A1, D17S5) and one short tandem repeat (ACTBP2) loci was assessed by polymerase chain reaction analysis of genomic DNA obtained from blood samples of eight human populations (Japanese, Northern Han, Hui, Uygur, Kazakh, Saudi Arabian, Greek, Italian). Allele frequencies at all loci were in the Hardy-Weinberg equilibrium for each population. With the exception of ACTBP2, the allelic distribution patterns for these loci revealed a marked genetic divergence among the eight populations. A dendrogram constructed by the neighbor-joining method based on the allele frequencies of the five loci suggested that the five Asian populations (Japanese, Northern Han, Hui, Uygur, and Kazakh) formed one cluster, whereas the two European populations and one West Asian population (Italian, Greek, and Saudi Arabian) formed another. The genetic relationship among these populations may have been greatly influenced by admixture as a result of the migration of individuals along the Silk Road throughout history.
Localized Single-Cell Lysis and Manipulation Using Optothermally-Induced Bubbles

Localized single cells can be lysed precisely and selectively using microbubbles optothermally generated by microsecond laser pulses. The shear stress from the microstreaming surrounding laser-induced microbubbles and direct contact with the surface of expanding bubbles cause the rupture of targeted cell membranes. High-resolution single-cell lysis is demonstrated: cells adjacent to targeted cells are not lysed. It is also shown that only a portion of the cell membrane can be punctured using this method. Both suspension and adherent cell types can be lysed in this system, and cell manipulation can be integrated for cell–cell interaction studies.
On the order of vanishing of Stickelberger elements of Hilbert modular forms

We construct Stickelberger elements for Hilbert modular cusp forms of parallel weight 2 and use recent results of Dasgupta and Spieß to bound their order of vanishing from below. As a special case the vanishing part of Mazur and Tate's refined ‘Birch and Swinnerton‐Dyer type'‐conjecture for elliptic curves of rank 0 follows.
The Relationship between Bladder, Periarterial and Somatic Neuropathy in Diabetes

Objective Diabetes commonly affects the bladder nerves. However, the relationship among bladder, periarterial and somatic neuropathy in diabetes is not well known. In the present study we investigated these relationships. Methods A total of 110 diabetic subjects were enrolled in the study. All were referred for screening for diabetic neuropathy, irrespective of their symptoms. The patients included 61 men and 49 women; the mean age was 59.3 years (31-85 years); the mean disease duration was 14.0 years (5-30 years); and the mean HbA1c value was 10.1% (5.1-16.3%). We performed a nerve conduction study (NCS, A-alpha/beta and B fiber), ultrasound-based measurement of the post-void residual (PVR) volume (abnormal, >50 mL, mainly A-delta/C fiber) and postural blood pressure measurement (abnormal, >-20 mmHg, A-delta/C fiber). Fisher's exact probability test and Student's t-test were used to analyze the significance of differences. Results NCS abnormality, an abnormal PVR volume, and postural hypotension were noted in 74, 19, and 36 of the subjects, respectively. There were clear relationships between NCS and an abnormal PVR volume (p<0.05), postural hypotension and an abnormal PVR volume (p<0.05), or NCS and postural hypotension (p<0.01). There were also subjects who had NCS abnormality alone, a high PVR volume alone or postural hypotension alone. An abnormal PVR volume was not associated with the HbA1c value, but was clearly related to the duration of diabetes (p<0.05). Conclusion Bladder dysfunction was correlated with somatic and periarterial neuropathy. On the other hand, 16% of the cases of bladder dysfunction occurred in patients without somatic or periarterial neuropathy; thus, the regular measurement of the PVR volume is necessary.
Resource-Based View of Information Systems: Sustainable and Transient Competitive Advantage Perspectives

The resource-based view (RBV), or resource-based theory, is one of the oldest and most influential theories in the field of information systems. This paper contends that it is timely to revisit, reflect on, and reposition RBV to ensure its continued disciplinary relevance and progress. In doing so, this paper (i) provides a succinct and sharp evaluation of the conventional RBV of information systems that firms use to establish sustainable competitive advantage, and (ii) makes an original contribution by introducing a contemporary RBV of information systems that firms can use to establish transient competitive advantage. Both these contributions should advance the current and future understanding of information systems as (a) an internal firm resource, (b) a source of competitive advantage, and (c) a driver of firm performance.
Relation Extraction and Discovery from Free Texts via Bootstrapping

Considering the problem of extracting binary relations from free texts for different domains, we use a universal method with no human supervision. Previous methods based on machine learning tended to extracting relations for a specific domain. When applying to different domains, these methods needed to be retrained based on new features and large amounts of manually labeled data. In this paper, we propose a bootstrapping method of relation extraction which can be adapted to different domains without training and utilizing of domain specific features. Firstly, a set of seeds is generated and the contexts of sentences which contain seeds are extracted as 5-tuples. Secondly, 5-tuples are clustered based on a small set of domain independent features. Thirdly, the 5-tuple whose feature vector has the highest similarity with the central vector of each cluster is chosen as a candidate pattern. Finally, all candidate patterns are evaluated and only the reliable patterns are selected for extracting new relations which shall be added to the set of seeds in next iteration. The experimental results show that our approach outperforms several other methods.
Primary screening of diabetic retinopathy based on integrating morphological operation and support vector machine

Diabetic retinopathy is one of the most frequent causes of blindness due to diabetes. Primary screening is essential due to prerequisite step toward the diagnosis of diabetic retinopathy in order to prevent vision loss or blindness. This paper presents the methods to discriminate between healthy images and diabetic retinopathy images on the retinal images. The proposed method involves three main steps. Initially, the image is preprocessed to remove small noises and enhance the contrast of the image. Secondly, Kirsch edge detection is utilized to detect the bright lesions. Subsequently, the red lesions are detected depending on top-hat morphological filtering methods. Then the bright and dark lesions are combined by using logical AND operator. In order to be left only pathological signs, the noises near the vicinity of the optic disc and blood vessels are further removed using blob analysis. Finally, morphological features are extracted and fed to the SVM classifier. The proposed method was evaluated with three datasets containing 229 images. It achieved the accuracy of 90%, sensitivity of 86.33% and specificity of 98.55% with the average computational time 8 seconds per image. The method is simple and fast, easy to implement and the result is promising.
Macronutrient intake associated with weight gain in adolescent girls with anorexia nervosa

OBJECTIVE Adolescents and women with anorexia nervosa (AN) are known to severely restrict total calorie and fat intake. However, data are limited regarding specific macronutrient intake associated with weight gain in AN. OBJECTIVE To prospectively investigate dietary macronutrient composition associated with weight gain in adolescent girls with AN. METHOD A prospective naturalistic study of 90 girls 12-18 years old; 45 with AN and 45 healthy normal-weight-controls over a 6-12-month period. Participants completed four-day food diaries and underwent body composition assessment using dual energy X-ray absorptiometry. Weight gain was defined as a ≥10% increase in body mass index (BMI) from baseline. RESULTS Baseline clinical characteristics did not differ between girls with AN who did not gain weight (AN-0) versus those who did (AN-1) over the following 6-12 month period except for percentage of calories from proteins (p = 0.046). At 6-12 month follow-up, AN-1 consumed a lower percentage of total calories from protein (p = .001), and a higher percentage of total calories from fat (p = .02) compared to AN-0. AN-1 had a significant increase in the percentage of total calories obtained from and poly-unsaturated-fatty acids (PUFA) (p = 0.006) compared to AN-0, between baseline and follow-up. Within the AN group, BMI at follow-up was associated positively with percentage of total calories obtained from fat, MUFA, and PUFA (p < .05) at 6/12 months, and inversely with the percentage of total calories obtained from carbohydrates and proteins (p = .03). DISCUSSION Consuming a greater proportion of total calories from fat is associated with weight gain in adolescent girls with AN.
A single-phase, Pwm multilevel inverter with boosted output voltage

Splitting of a dc voltage source with two capacitor banks has been the approach in generating 5-level output voltage with single-and three-phase full-bridge circuits and added bidirectional switch. Associated with this configuration is the problem of voltage imbalance between the splitting capacitor banks. Also, the inverter output voltage magnitude is obviously limited to the value of the split input dc voltage source. Presented in this paper is a unit topology for single-phase 5-level multilevel inverter, MLI. It simply consists of a full-bridge circuit, a capacitor bank, charge-discharge unit and a dc source. The charge-discharge unit with the capacitor bank is the interface between the full-bridge and the dc source. The proposed unit cell can generate a 5-level output voltage waveform whose peak value is twice the dc input voltage value. Simulation and experimental verifications are carried out on the proposed inverter topology for an R-L load. Results are adequately presented.
