Hidden Web Data Extractor Komal Taneja

In present scenario, WWW is very important and most common place for the users of the internet. We are facing a world with ever growing data. This data is stored in documents in networks. The most prominent of these networks is the World Wide Web often referred to as the Internet. Finding and retrieving information or documents in a large environment is a huge task. For this reason crawlers have been developed. They traverse over a subset of the Internet, and try to index the pages according to their relevance. Due to the fact that the Internet is huge and ever growing, crawlers can only view a subset of the internet. Thus one large problem of crawlers is to select the relevant pages of the Internet and index them accordingly. The modern Internet nowadays also contains multimedia contents like video images and audio files. Extracting information from these data sources and indexing these is a major challenge for modern crawlers. The aim of our research is to develop a crawler capable of querying and extracting the data from the hidden web database. This system will allow a user to submit desired query or keywords on a form-based interface and crawler extract required data from the hidden web not the hyperlinks that traditional crawlers does.

Association of PTPN22 polymorphsims and ankylosing spondylitis susceptibility.

BACKGROUND As a susceptibility gene for AS, the polymorphsims of PTPN22 associated with disease susceptibility. METHODS We selected two SNPs of rs1217406 and rs1217414 within PTPN22 with Haploview software and investigated the relationship between the SNPs of PTPN22 gene and AS susceptibility. 120 AS patients and 100 healthy people were enrolled from Qilu Hospital of Shandong University. And we genotyped the SNPs of PTPN22 with PCR-RFLP method. RESULTS The results showed that C allele (rs1217406) and T allele (rs1217414) both were risk factors for AS (OR: 3.12, 2.13). The persons with A-T, C-C or C-T haplotypes were more likely to suffer AS (OR: 3.17, 3.66, 4.011). CONCLUSIONS Due to the close relationship of PTPN22 and AS, the study may be helpful for the early diagnosis and differential diagnosis.
Who is at risk of emotional problems and how do you know? Screening of women going for IVF treatment.

BACKGROUND Fertility problems are accompanied by a lot of emotional distress, resulting in a considerable proportion of female patients showing severe maladjustment after assisted reproductive technology. Although this interferes with their daily life, emotional distress has also shown to be related to dropout of treatment and deterioration of health behaviour. Early identification of women at risk enables the provision of timely psychosocial support and the focusing psychosocial resources on those who need it most. This study investigated the psychometric characteristics of a screening tool SCREENIVF to identify women at risk of emotional problems at an early stage of treatment. METHODS Risk factors for emotional maladjustment were identified in a previous study and incorporated in SCREENIVF which consists of 34 items on general and infertility specific psychological factors. A group of 279 women in their first IVF treatment cycle completed SCREENIVF at both pretreatment and 3-4 weeks after the pregnancy test. Linear Regression analyses were performed to investigate the predictive value of SCREENIVF, and sensitivity and specificity as well as likelihood ratios were described. RESULTS SCREENIVF successfully identified 75% of the patients as at risk or not at risk. The negative predictive value was high: 89%. The positive predictive value was low (48% in the total sample and 56% after unsuccessful treatment). Sensitivity was 69%, specificity was 77%. CONCLUSIONS For its use as a first screening for emotional problems, SCREENIVF is an acceptable instrument to identify women at risk. These women could be offered more detailed diagnostics e.g. an interview to further investigate to what extent they could benefit from psychological treatment. In addition, physicians can anticipate on this risk profile when communicating with these patients.
Seven Problems of Online Group Learning (and Their Solutions)

The benefits of online collaborative learning, sometimes referred to as CSCL (computer-supported collaborative learning) are compelling, but many instructors are loath to experiment with non-conventional methods of teaching and learning because of the perceived problems. This paper reviews the existing literature to present the seven most commonly reported such problems of online group learning, as identified by both researchers and practitioners, and offers practical solutions to each, in the hope that educators may be encouraged to “take the risk”.
Recommending Talks at Research Conferences Using Users' Social Networks

This paper investigates recommendation algorithms to suggest talks of interest to attendees of research conferences. In this study, based on a social conference support system Conference Navigator 3 (CN3), we explored three kinds of knowledge sources to generate recommendations: users' preference about talks (CN3 bookmarks), users' social networks (research collaboration network and CN3 following network) and talk content information (titles and abstracts). Using these sources, we explored a diverse set of algorithms from non-personalized community vote-based recommendations and conventional collaborative filtering recommendations to hybrid recommendations such as social network-based (SN) recommendations boosted by content information of talks. We found that SN recommendations fused with content information outperformed the other approaches. Moreover, for cold-start users who have an insufficient number of bookmarks to express their preferences, the recommendations based on their social connections also .
Flavonoides de trece especies del género Bursera con potencial antioxidante.

RESUMEN: Se evaluo preliminarmente el potencial antioxidante de los flavonoides presentes en las hojas de trece especies del genero Bursera, procedentes de los Estados de Puebla y Guerrero, Mexico. Los extractos hidroalcoholicos (metanol 80%) de las hojas de cada especie, se analizaron por un sistema de cromatografia en capa fina automatizado para detectar y/o identificar los flavonoides, empleando estandares. La actividad antioxidante se determino in vitro por el metodo autobiografico y por espectrofotometria, en ambos casos basandose en la reduccion del radical DPPH (2,2-difenil-1-picrilhidracilo). Los resultados muestran que los flavonoides estan presentes en todos los extractos, la mayoria de estos presentaron un alto porcentaje de reduccion del DPPH al incrementar la concentracion de los extractos (10, 100 y 1000 ppm). La mayor actividad, en la mas baja concentracion probada, se observo en las especies B. aleoxylon, B. vejar-vazquezii (seccion Bullockia), B. grandifolia y B. morelensis (Seccion Bursera).
The Dutch Childhood Anxiety Sensitivity Index: Psychometric Properties and Factor Structure

Examined the reliability, validity, and factor structure of the Childhood Anxiety Sensitivity Index (CASI; Silverman, Fleisig, Rabian, & Peterson, 1991) in a Dutch sample. Five hundred forty-four Dutch schoolchildren between 8 and 16 years of age completed Dutch translations of the CASI; the State-Trait Anxiety Inventory for Children (Spielberger, Edwards, Lushene, Montuori, & Platzek, 1973); and the Fear Survey Schedule for Children-Revised (Ollendick, 1983). The Dutch CASI was found to have adequate internal consistency for use with children as well as adolescents. Results reveal that the CASI predicted fear beyond a measure of trait anxiety in this Dutch sample. Both exploratory and confirmatory factor analyses comparing different models were undertaken. The model with 3 first-order factors found in previous studies showed an acceptable fit in this cross-validation sample. Loadings on the 3 factors (Physical Concerns, Mental Concerns, and Publicly Observable Concerns) did not differ between children and adolescents. Results are compared with previous research on the CASI. Directions for future research are discussed.
Cardiovascular Hybrid Imaging using PET/MRI

Abstract The following overview provides a summary of the state of the art and research as well as potential clinical applications of cardiovascular PET/MR imaging. PET/MRI systems have been clinically available for a few years, and their use in cardiac imaging has been successfully demonstrated. At this period in time, some of the technical difficulties that arose at the beginning have been solved; in particular with respect to MRI-based attenuation correction, caution should be exercised with PET quantification. In addition, many promising technical options are still in the developmental stage, such as MRI-based motion correction of PET data resulting from simultaneous MR acquisition, and are not yet available for cardiovascular imaging. On the other hand, PET/MRI has been used to demonstrate significant pathologies such as acute and chronic myocardial infarction, myocarditis or cardiac sarcoidosis; future applications in clinical routine or within studies appear to be possible. In coming years additional studies will have to be performed to prove diagnostic gain at a reasonable cost-benefit ratio before valid conclusions are possible regarding the clinical utility and future of cardiovascular PET/MR imaging. Key Points: • The feasibility of cardiovascular PET/MRI has been successfully demonstrated and application in clinical routine is possible. • Initial experience suggests added value of PET/MRI with FDG in pathologies like acute myocardial infarction, myocarditis, cardiac sarcoidosis and cardiac tumors. • Technical improvements in the field of attenuation correction and MRI-based motion correction as well as new PET tracers could result in new applications for cardiovascular PET/MRI in next years.

Desvenlafaxine 50 and 100 mg/d versus placebo for the treatment of major depressive disorder: a phase 4, randomized controlled trial.

OBJECTIVE To assess short-term efficacy and safety of desvenlafaxine 50 and 100 mg/d versus placebo for treating major depressive disorder (MDD). Assessment of sexual function was a secondary objective. METHOD Outpatients (≥ 18 years) who met criteria for MDD from the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision and had screening and baseline 17-item Hamilton Depression Rating Scale (HDRS17) total scores ≥ 20 were randomly assigned to placebo or desvenlafaxine 50 or 100 mg/d in an 8-week study conducted from October 2011 to August 2012. The primary efficacy end point was change from baseline in HDRS17 total score at week 8, analyzed using a mixed-effects model for repeated measures. Sexual function was assessed using the Arizona Sexual Experiences Scale (ASEX). RESULTS The safety population included 909 patients (intent-to-treat population, n = 886). Significantly greater improvement in adjusted mean HDRS17 total score from baseline to week 8 was observed for desvenlafaxine 50 mg (-11.28; P = .006) and desvenlafaxine 100 mg (-11.67; P < .001) compared with placebo (-9.71), with adjustment for multiplicity. In the ASEX total score analysis (n = 422), the treatment by gender interaction was not significant; thus, genders were combined for subsequent analyses. Comparisons for desvenlafaxine versus placebo for change from baseline in ASEX total and all item scores found P > . 05, with no adjustment for multiplicity. Rates of sexual dysfunction based on ASEX were comparable among treatment groups. CONCLUSIONS These results support previous findings demonstrating antidepressant efficacy, safety, and tolerability of desvenlafaxine 50 and 100 mg/d versus placebo. Sexual function was comparable between desvenlafaxine and placebo. TRIAL REGISTRATION ClinicalTrials.gov identifier: NCT01432457.
Implementation of the MFCC front-end for low-cost speech recognition systems

Speech recognition front-end implemented using a high-end floating-point processor is expensive both in terms of computer resources and cost. This paper presents a new small footprint MFCC front-end design that is suitable for low-cost speech recognition systems. By exploiting the overlapping nature of the input frames and by adopting a simple pipeline structure, the implemented design only utilizes approximately 10% total resources of a low-cost and modest-size FPGA device, thus leaving significant space for speech recognition post-processing.
The nucleotide mapping of DNA double‐strand breaks at the CYS3 initiation site of meiotic recombination in Saccharomyces cerevisiae.

Initiation of meiotic recombination in the yeast Saccharomyces cerevisiae occurs by localized DNA double‐strand breaks (DSBs) at several locations in the genome, corresponding to hot spots for meiotic gene conversion and crossing over. The meiotic DSBs occur in regions of chromatin that are hypersensitive to nucleases. To gain insight into the molecular mechanism involved in the formation of these DSBs, we have determined their positions at the nucleotide level at the CYS3 hot spot of gene conversion on chromosome I. We found four major new features of these DSBs: (i) sites of DSBs are multiple with varying intensities and spacing within the promoter region of the CYS3 gene; (ii) no consensus sequence can be found at these sites, indicating that the activity involved in DSB formation has little or no sequence specificity; (iii) the breaks are generated by blunt cleavages; and (iv) the 5′ ends are modified in rad50S mutant strains, where the processing of these ends is known to be prevented. We present a model for the initiation of meiotic recombination taking into account the implications of these results.
Selective Attention to Stimulus Features Modulates Interocular Suppression

Psychological and neurophysiological studies have shown that attention modulates various sorts of perceptual processing. Here, we report that attention affects the perceptual dominance of binocular rivalry. Experiments using a dichoptic masking paradigm revealed that when an observer was attending to one of the two orientations of the elements of a monocular texture, a texture briefly presented to the opposite eye suppressed the perception of the elements with the attended orientation, while the elements with the orientation which was ignored sustained their dominance. Moreover, subsequent experiments indicated that the suppression depended on the orientation of the texture elements constituting the mask, but was independent of their locations. These results suggest that attention to specific features modulates interocular suppression in a mode which is different from that found in a previous study [Ooi and He, 1999 Perception 28 551–574].
Stick-Slip Dynamics of a Two-Degree-of-Freedom System

Two-degree-of-freedom autonomous system with friction is analyzed numerically. The friction coefficient has been smoothened using arc tan function. The standard, but slightly modified chaos identification tools have been applied for the analyzed discontinuous system. Some interesting examples of stick-slip regular and chaotic dynamics have been illustrated and discussed.
Hardware accelerated power estimation

In this paper, we present power emulation, a novel design paradigm that utilizes hardware acceleration for the purpose of fast power estimation. Power emulation is based on the observation that the functions necessary for power estimation (power model evaluation, aggregation, etc.) can be implemented as hardware circuits. Therefore, we can enhance any given design with "power estimation hardware", map it to a prototyping platform, and exercise it with any given test stimuli to obtain power consumption estimates. Our empirical studies with industrial designs reveal that power emulation can achieve significant speedups (10X to 500X) over state-of-the-art commercial register-transfer level (RTL) power estimation tools.
Relationship between 17-hydroxyprogesterone responses to human chorionic gonadotropin and markers of ovarian follicle morphology in women with polycystic ovary syndrome.

CONTEXT Women with polycystic ovary syndrome (PCOS) have increased 17-hydroxyprogesterone (17-OHP) responses to gonadotropin stimulation although individual variability is substantial, as reflected by exaggerated as well as normal responses. The relationship between 17-OHP responses to gonadotropin stimulation and markers of ovarian function has not been assessed. OBJECTIVE To determine whether 17-OHP responses are associated with antral follicle count (AFC), anti-Mullerian hormone (AMH), or inhibin B (Inh B) levels in PCOS and normal women. DESIGN Prospective study. SETTING Research center at an academic medical center. PARTICIPANTS Women with PCOS (n = 18) and normal controls (n = 18). INTERVENTIONS Blood samples were obtained before and 24 hours after administration of 25 μg recombinant-human chorionic gonadotropin. Ovarian imaging was conducted with three-dimensional pelvic ultrasound. MAIN OUTCOME MEASURES Basal and stimulated levels of 17-OHP, androgens, estrogen, AMH, Inh B, and AFC. RESULTS In women with PCOS, 17-OHP responses were heterogeneous and inversely correlated with AMH and Inh B levels, but not AFC. In a subgroup of PCOS women with exaggerated 17-OHP responses, AMH levels were equivalent to that of normal women. In PCOS women with normal 17-OHP responses, AMH levels were markedly elevated. CONCLUSION Based on heterogeneous 17-OHP responses to human chorionic gonadotropin in women with PCOS, AMH levels are inversely linked to ovarian androgen production while positively correlated with AFC. These findings suggest that in PCOS, AMH production may reflect redistribution of the follicle population or regulation by intraovarian mechanisms.
In vivo MRI cell tracking: clinical studies.

OBJECTIVE The purpose of this review is to describe the principles of MRI cell tracking with superparamagnetic iron oxides and the four clinical trials that have been performed. CONCLUSION Clinical MRI cell tracking is likely to become an important tool at the bedside once (stem) cell therapy becomes mainstream. The most prominent role of this technique probably will be verification of accurate cell delivery with MRI-guided injection, in which interventional radiologists will play a role in the near future. All clinical studies described as of this writing have been performed outside the United States.
DNA Marker Technologies in Plants and Applications for Crop Improvements

Over the past several decades, especially through traditional breeding programme, intensive attempts have been made for the improvement of a large number of cereal varieties which adjusted to diverse agro-ecologies. However, increasing biotic and abiotic stresses, increasing populations, and sharply reducing natural resources especially water for agricultural purposes, push the breeders for organizing and developing improved cereal varieties with higher yield potential. In combination with developments in agricultural technology, plant breeding has made remarkable progress in increasing crop yields for over a century. Molecular markers are widely employed in plant breeding. DNA markers are being used for the acceleration of plant selection through marker-assisted selection (MAS). Genes of agronomic and scientific importance can be isolated especially on the basis of their position on the genetic map by using molecular markers technologies. In this review, the current status of marker development technologies for crop improvements will be discussed. It will also provide an outlook into the future approaches and most widely used applications in plant breeding in crop plants on the basis of present development.
Antibiotics and Antibiotic resistance determinants : an undesired element in the environment

The rapid development of resistance in bacteria is an evolutionary response to the selective pressure of antibiotics and results from natural selection. It is established that microbial adaptation evolves, and the cause for the development of antibiotic resistance is the widespread misuse of antibiotics. Pollution of the environment by antibiotic resistance genes can increase the chances of human pathogens for acquiring resistance. The release of residues containing human microbiota into environments containing bacteria enriched in resistance elements increases the possibility of acquiring novel resistance determinants by human-linked bacteria. The spread of resistance genes in natural ecosystems can challenge the population dynamics and the physiology of natural microbial populations. Active stewardship is needed to avoid gene flow to and from environmental resistance reservoirs. In this chapter, we discuss the dissemination of antibiotics resistance genes (ARGs) and antibiotics resistance bacteria (ARB) in the environment, with emphasis on how these elements interact with and affect the health and general wellbeing of human and natural ecosystems.
Measurements of temperature and humidity between the clothes and the body

The paper describes a series of observations made in a well-built room in south-west Persia. A study was made of conditions of temperature and humidity in the room, and between the clothes and the body. Observations were made in the cold and the hot seasons. In spite of the great contrast which prevailed in the room at these two seasons, there was very little difference on the surface of the body. The observations are consistent with those published by Mellanby, who worked under a wide range of artificially produced climatic conditions.
The Potential Hedonic Role of Olfaction in Sexual Selection and its Dominance in Visual Cross-Modal Interactions

Perfumes are commonly used to cover body odour, or to provide a positive, attracting, and interesting impact, or a smell that belongs to a social group. A role in sexual communication of such non-pheromonal olfactory cues has been suggested in the literature. However, there remain the questions whether these stimuli are involved in human chemosexual communication and, if so, at what level, and whether they interact with other sensorial modalities, in particular vision. To answer these, we investigated the influence of male and female perfumes as non-conscious stimulation during visual assessments of a range of facial qualities across and within the sexes. The female subjects were in their ovulatory phase, to avoid changes in perception across the menstrual cycle. Our data indicate that non-pheromonal olfactory cues are potentially involved in mate choice and may elicit strong hedonic responses that can dominate visual signs, with a cross-modal interaction.
