User behavioural patterns and reduced user profiles extracted from log files

This paper is focused on log files where one log file attribute is an originator of the recorded activity (originator is a person in our case). Hence, based on the similar attributes of people, we are able to construct models which explain certain aspects of a persons behaviour. Moreover, we can extract user profiles based on behaviour and find latent ties between users and between different user groups with similar behaviours. We accomplish this by our new approach using the methods from log mining, business process analysis, complex networks and graph theory. The paper describes the whole process of the approach from the log file to the user graph. The main focus is on the step called `The finding of user behavioural patterns'.
Urban Politics Reconsidered

Over the past three decades, research in urban politics or increasingly urban governance reveals a landscape powerfully reflecting what might now be defined as a post-political consensus. Following a waning of the community power, urban managerialist and collective consumption debates, this ‘new urban politics’ has appeared conspicuously absorbed with analysing a purported consensus around economic growth alongside a proliferation of entrepreneurially oriented governing regimes. More recent contributions, acknowledging the role of the state and governmentalities of criminal justice, uncover how downtown renaissance is inscribed through significant land privatisations and associated institutionalised expressions like Business Improvement Districts and other ‘primary definers’ of ‘public benefit’: all choreographed around an implicit consensus to ‘police’ the circumspect city, while presenting as ultra-politics anything that might disturb the strict ethics of consumerist citizenship. Beyond downtown, a range of shadow governments, secessionary place-makings and privatisms are remaking the political landscape of post-suburbia. It is contended that the cumulative effect of such metropolitan splintering may well be overextending our established interpretations of urban landscapes and city politics, prompting non-trivial questions about the precise manner in which political representation, democracy and substantive citizenship are being negotiated across metropolitan regions, from downtown streetscape to suburban doorstep. This paper suggests that recent theorisations on post-democracy and the post-political may help to decode the contemporary landscape of urban politics beyond governance, perhaps in turn facilitating a better investigation of crucial questions over distributional justice and metropolitan integrity.
Pilot Test of a Peer-Led Small-Group Video Intervention to Promote Mammography Screening Among Chinese American Immigrants

This study evaluated the feasibility, acceptability, and potential effect of a small-group video intervention led by trained Chinese American lay educators who recruited Chinese American women not up to date on mammography screening. Nine lay educators conducted 14 Breast Health Tea Time Workshops in community settings and private homes that started with watching a culturally tailored video promoting screening followed by a question-and-answer session and distribution of print materials. Many group attendees did not have health insurance or a regular doctor, had low levels of income, and were not proficient in English. Forty-four percent of the attendees reported receipt of a mammogram within 6 months after the small-group session, with higher odds of screening among women who had lived in the United States less than 10% of their lifetime. Four of the educators were very interested in conducting another group session in the next 6 months.
EFFECT OF VITAMIN C SUPPLEMENTATION ON THE PERFORMANCE OF DESI, FAYOUMI AND COMMERCIAL WHITE LEGHORN CHICKEN EXPOSED TO HEAT STRESS

Sixty layers (50 weeks of age) each of native Desi, Fayoumi and commercial White Leghorn (Nick Chick) were kept in wire cages following completely randomized design for 8 weeks during summer season (June and July). The birds of each type were divided into two groups i.e. with and without supplementation of vitamin C with three replicates assigned to each layer group (10 birds in each replicate). The vitamin C (C-vit fort) was added at the rate of 5 ml/5 liter in drinking water throughout the experimental period in respective layer group. The results indicated that the mean egg production, egg weight and egg shell thickness improved (P<0.05) with supplementation of vitamin C in all layers. The average feed consumption of three types of layers was also improved (P<0.05) with supplementation of vitamin C. The blood picture showed that the concentration of ascorbic acid was higher (P<0.05) in groups supplemented with vitamin C. However, the concentrations of blood enzymes (ALP, SGPT and SGOT) were lowered (P<0.01) with vitamin C supplementation in all types of layers. Based on the findings of the present study, it was concluded that vitamin C supplementation was effective in improving performance of layers under heat stress conditions.
Face Recognition based on a Hybrid Meta-Heuristic Feature Selection Algorithm

For the past few years, a number of new face recognition techniques have been proposed. Always it is a big unanswered question among face recognition researchers about which method or technique will have better performance. In this study an approach to recognize known faces based on Eigen vectors and a hybrid Meta-heuristic feature selection algorithm is proposed. The eigenvectors which are covariance matrix of the face images together describes the difference between face images. Face recognition problem is viewed as a two dimensional recognition problem. Initially the face images are projected in to face space and using Principal component analysis the eigenvectors with high Eigenvalues are extracted to reduce the dimension of the feature vector. Further to select the best feature vectors which increase the classification accuracy is selected by using a hybrid metaheuristic algorithm using Genetic algorithm (GA) and Bacteria Foraging Optimization (BFO). In this study the Support vector machine (SVM) and Back propagation neural network (BPNN) are used for classification. The classifiers are trained and tested separately using the frontal face images taken from AT&T database. The SVM and BPNN produces an average classification accuracy of 82.6% and 83.28% respectively.
A 23.5GHz PLL with an adaptively biased VCO in 32nm SOI-CMOS

A 30% frequency tuning range 23.5GHz 32nm SOI-CMOS PLL features an adaptively biased VCO. Adaptive biasing of the VCO lowers the average PLL power consumption from 34mW to 24mW, while keeping the jitter below 1.5° RMS across all frequency bands.
Evaluation of alternating and sustained attention in a sample of healthy adults with high level of schooling

This study aimed the evaluation of the alternating and sustained attentional functions performance in a sample of an adult Brazilian population with high level of schooling. Were evaluated 14 subjects between 45 and 59 years old with level of schooling equal or higher than 18 years. The evaluation was conducted through semistructered interview, MEEM, depression and anxiety scale and neuropsychological tests, with focus on Trail Making Test. A descriptive analysis was performed in the TMT A and the TMT B and the results were within the expected age of the subjects. These data corroborate with studies that show the influence of time of schooling on achievement and learning of a cognitive-motor task and may contribute to the future performance comparisons between different age groups, since there are just a few findings which evaluate the intermediate age groups.
[Effects of extremely low frequency electromagnetic fields on male reproduction in mice].

OBJECTIVE To investigate the effects of extremely low frequency electromagnetic fields (ELF EMFs) on male reproduction in mice. METHODS 94 adult male mice were exposed to 50 Hz sinusoidal electromagnetic fields of 0.2, 3.2 or 6.4 mT for 2 weeks or 4 weeks. Testicular histology and weight, sperm amount, sperm motility and morphology were measured. The percentages of different ploidy cells and cell phases, and DNA content of testis cells were estimated by flow cytometry. The micronucleus rate of bone-marrow cell was also observed. RESULTS The testicular weight of the mice exposed to 6.4 mT for 4 weeks [(76.06 +/- 32.25) mg] was significantly lower than that of the control [(111.44 +/- 19.99) mg, P < 0.05]; no significant histopathological changes were observed on the testis in EMFs exposed mice;the sperm amount was decreased after EMFs exposure for 4 weeks, and those of the mice exposed to 0.2 mT and 6.4 mT for 4 weeks [(4.87 +/- 0.94) x 10(6)/ml and (4.30 +/- 1.89) x 10(6)/ml respectively] were significantly lower than that of the control [(6.67 +/- 0.70) x 10(6)/ml, P < 0.05]; the rates of sperm motility also showed a decline. After 0.2, 3.2 or 6.4 mT EMFs exposure for 2 weeks, the deformity rates of sperm [(7.416 +/- 3.352)%, (6.862 +/- 2.947)% and (8.112 +/- 4.615)% respectively] were significantly higher than that of the control [(4.098 +/- 2.028)%, P < 0.01]. Similarly, those of the mice exposed for 4 weeks [(10.267 +/- 3.836)%, (11.027 +/- 7.059)%, (8.814 +/- 3.678)% respectively] were higher than that of the control [(3.714 +/- 1.830)%]. After 6.4 mT exposure for 2 weeks, the percentages of 1C testis cells [(69.56 +/- 4.07)%] was significantly lower than that of the control [(73.45 +/- 3.10)%, P < 0.05]. There were not any remarkable changes in those of 2C, 4C cells. DNA content in different ploidy cells of the mice exposed to 6.4 mT was decreased. Moreover, the cell percentage in S phase was increased significantly (P < 0.01). CONCLUSION ELF EMFs exposure may have some adverse effects on reproduction in mice.
Face recognition in infants: A review of behavioral and near‐infrared spectroscopic studies

Recent developmental studies investigating face recognition ability in infants’ have provided evidence not only that infants show selective attention to faces, but also that they can discriminate between faces from birth, and that biases in face processing such as the face inversion and other race effects exist even in infancy. Studies measuring the hemodynamic responses to facial images in the infants’ brain using near-infrared spectroscopy (NIRS) have also reported differential cortical activity in response to face and nonface images in infants. This paper will review recent findings on infants face recognition provided by both behavioral studies and neuroimaging studies using NIRS. These converging lines of evidence point to the early onset of face recognition ability in infancy.
Characterization of quasi-symmetric designs with eigenvalues of their block graphs

A quasi-symmetric design (QSD) is a (v, k, λ) design with two intersection numbers x, y, where 0 ≤ x < y < k. The block graph of a QSD is a strongly regular graph (SRG), whereas the converse is not true. Using Neumaier’s classification of SRGs related to the smallest eigenvalue, a complete parametric classification of QSDs whose block graph is an SRG with smallest eigenvalue −3, or second largest eigenvalue 2, is obtained.
The Construction and Analysis of Baidu Baike Entry Network

Network has become the key method to analysis the interacting targets. The Baidu Baike entry network was constructed by means of Baidu Baike entry related terms and term category attributes. And then according to the feature of the closely connection in communities and the sparsely connection between communities in organization structure, it can reveal the relationship between the different entries in Baidu Baike. Many experiments show that communities of the Baidu Baike entry network have many overlap relations which explain that many Baidu Baike entries have rich meanings. And it is also found size and edge of community have a relationship of law of power function, which provides a reference about studying whether communities still have a large number of overlapping relationships when the network scale expand.
Effect of methylphenidate treatment on appetite and levels of leptin, ghrelin, adiponectin, and brain-derived neurotrophic factor in children and adolescents with attention deficit and hyperactivity disorder

Abstract Objectives. We aimed to explore whether the use of methylphenidate relates leptin, ghrelin, adiponectin, and brain-derived neurotrophic factor (BDNF). In addition, the relationship between methylphenidate-related weight loss in attention deficit hyperactivity disorder (ADHD) patients and these biomolecules were evaluated. Methods. Thirty ADHD patients receiving methylphenidate and 20 healthy controls were included. Leptin, ghrelin, adiponectin, and BDNF levels were measured at baseline and after two-month treatment in both groups. Results. At baseline, leptin, ghrelin, adiponectin, and BDNF levels were similar in the ADHD and control groups. The most common adverse events occurring in the ADHD group after a 2-month treatment period included loss of appetite (70%) and weight loss (66.7%). A significant difference was found in body weight, BMI, and CGI scores of the ADHD patients after the treatment. While post-treatment ghrelin and adiponectin levels were significantly higher in the ADHD group, BDNF level was significantly lower. Post-treatment decrease in leptin levels was not significant. Conclusions. Leptin and BDNF were not associated with poor appetite and/or weight loss due to methylphenidate treatment. However, ghrelin and adiponectin might be biomolecules that play a role in underlying neurobiological mechanisms of methylphenidate-related appetite or weight loss.
Biomarker-driven population enrichment for adaptive oncology trials with time to event endpoints.

The development of molecularly targeted therapies for certain types of cancers has led to the consideration of population enrichment designs that explicitly factor-in the possibility that the experimental compound might differentially benefit different biomarker subgroups. In such designs, enrollment would initially be open to a broad patient population with the option to restrict future enrollment, following an interim analysis, to only those biomarker subgroups that appeared to be benefiting from the experimental therapy. While this strategy could greatly improve the chances of success for the trial, it poses several statistical and logistical design challenges. Since late-stage oncology trials are typically event driven, one faces a complex trade-off between power, sample size, number of events and study duration. This trade-off is further compounded by the importance of maintaining statistical independence of the data before and after the interim analysis and of optimizing the timing of the interim analysis. This paper presents statistical methodology that ensures strong control of type-1 error for such population enrichment designs, based on generalizations of the conditional error rate approaches of Müller and Schäfer [8] and Irle and Schäfer [12]. The special difficulties encountered with time-to-event endpoints are addressed by our methods. The crucial role of simulation for guiding the choice of design parameters is emphasized. Although motivated by oncology, the methods are applicable as well to population enrichment designs in other therapeutic areas.
Oviposition behavior of Haemagogus leucocelaenus (Diptera: culicidae), a vector of wild yellow fever in Brazil

ABSTRACT Haemagogus leucocelaenus, which is considered a major vector of wild yellow fever, exhibits acrodendrophilic habits and mainly deposits its eggs in treeholes and bamboo internodes. The selection of nursery sites is essential in the life history and reproductive success of mosquitoes. The present work investigated the preferred oviposition height and period of Hg. leucocelaenus in an Atlantic forest area in Rio de Janeiro. Sampling was performed using oviposition traps that were placed on plant material at 0, 2, 4, 6, and 8 m above the ground, from August 2015 to July 2016. Eggs were more abundant during October and May, and the height of traps placement had no significant effect on the eggs number indicating that Hg. leucocelaenus explores different levels of forest habitats, a behavior that may favor the transmission of pathogens among arboreal animals including primates and humans. The findings of the present study are discussed from an ecological and epidemiological point of view.
A dominant mutation reveals asymmetry in MP/ARF5 function along the adaxial-abaxial axis of shoot lateral organs

The establishment of adaxial-abaxial polarity in plant lateral organs involves elaborate interactions between members of several transcription factor families, including the Auxin Response Factors (ARFs). We previously described a dominant allele of ARF5/MONOPTEROS (MP), termed MPΔ, which causes severe vascular hypertrophy in shoot lateral organs. Here we report that these organs are also disrupted in adaxial-abaxial polarity. Other MPΔ lateral organs with decreased vasculature show similar disruptions, suggesting that MP impinges on organ polarity through pathways separate from its role in promoting vascularization. Furthermore, we demonstrate that MPΔ exhibits an adaxial-abaxial asymmetry in its ability to influence organ development. Since ARFs previously implicated in polarity establishment function as transcriptional repressors, the transcriptional activator MP represents a novel link between auxin signal transduction and adaxial-abaxial polarity.
Identification of a degradation in postural equilibrium invoked by different vibration frequencies on the tibialis anterior tendon

The aim of the study was to compare the effect of different vibration frequencies applied to the tibialis anterior tendon on the control of postural equilibrium. Sixty-three parameters were analyzed, with 44 of them showing an effect of vibration. The greatest differences were observed for those parameters related to movement in the anteroposterior direction. Such a result was due to the direction of postural sway induced by the vibration. There were no differences between the control condition and vibration at 50 Hz. However, both 70 and 90 Hz vibrations produced similar results. The method of postural perturbation presented here might be useful to test the sensitivity of parameters extracted from COP signals in terms of their capability to detect small changes in postural equilibrium
Optimizing Optimistic Concurrency Control for Tree-Structured, Log-Structured Databases

Scaling-out a database system typically requires partitioning the database across multiple servers. If applications do not partition perfectly, then transactions accessing multiple partitions end up being distributed, which has well-known scalability challenges. To address them, we describe a high-performance transaction mechanism that uses optimistic concurrency control on a multi-versioned tree-structured database stored in a shared log. The system scales out by adding servers, without partitioning the database. Our solution is modeled on the Hyder architecture, published by Bernstein, Reid, and Das at CIDR 2011. We present the design and evaluation of the first full implementation of that architecture. The core of the system is a log roll-forward algorithm, called meld, that does optimistic concurrency control. Meld is inherently sequential and is therefore the main bottleneck. Our main algorithmic contributions are optimizations to meld that significantly increase transaction throughput. They use a pipelined design that parallelizes meld onto multiple threads. The slowest pipeline stage is much faster than the original meld algorithm, yielding a 3x improvement of system throughput over the original meld algorithm.
Nexuses of knowledge and power in Afghanistan: the rise and fall of the informal justice assemblage

This article explores Western attempts to strengthen mechanisms of informal justice in Afghanistan. It traces the origins and evolution of an ‘informal justice assemblage’: the constellation of specific expert discourses, institutional practices, and strategic considerations that made it possible and plausible that Western actors should promote and work with informal processes of justice. The article problematizes expert statements that posit that working with informal justice is somehow more ‘Afghan-led’ and less of an outside imposition than supporting the country's formal justice system. To the contrary, this article details how – discursively and institutionally – academic authority about what is locally appropriate in practice served to foreclose national debate and scrutiny about the organization and administration of justice. This amounted to a net erosion of accountability, reinforced by the subsequent militarization of the justice sector and governance more broadly. In conclusion, the article calls for greater attention to the broader fields of power in which claims of sensitivity to the local sentiments and reality in Afghanistan are made.
Measurement and analysis of field emission electrons in the LCLS gun

The field emission was measured during the high- power testing of the LCLS photocathode RF gun. A careful study and analysis of the field emission electrons, or dark current is important in assessing the gun's internal surface quality in actual operation, especially those surfaces with high fields. The first indication of a good RF gun design and fabrication is short processing time to the required fields and low electron emission at high- fields. The charge per 2 microsecond long RF pulse (the dark charge) was measured as a function of the peak cathode field for the 1.6 cell, 2.856 GHz LCLS RF gun. Faraday cup data was taken for cathode peak RF fields up to 120 MV/m producing a maximum of 0.6 nC/RF pulse for a diamond-turned polycrystalline copper cathode installed in the gun. Digitized images of the dark charge were taken using a 100 micron thick YAG crystal for a range of solenoid fields to determine the location and angular distribution of the field emitters. The FN plots and emitter image analysis will be described in this paper.
Neural Prediction of Communication-Relevant Outcomes

Understanding the mechanisms of effective communication may be advanced by knowledge from social and cognitive neuroscience. We build on prior brain research that mapped mental processes, and describe a brain-as-predictor approach that encompasses studies that treat measures of brain activity in response to communication relevant tasks as: 1) mediators between communication relevant stimuli and outcomes, 2) moderators of the relationship between communication relevant stimuli and outcomes or 3) direct predictors of communication relevant outcomes. In this article, we give a detailed description of the brain-as-predictor approach and provide a guide and checklist for interested authors, reviewers and editors. We discuss how the approach can provide theoretical insights and advance practical applications in communication research. Given its potential for advancing theory and practice, we argue that the brain-as-predictor approach can complement other communication research methods and serve as a valuable addition to the communication science toolbox.
