Take me to SSD: a hybrid block-selection method on HDFS based on storage type

As the era of Big-data has risen, the importance of big data technologies is also increasing day by day. Especially, Hadoop has become a critical part of the overall Big-data system because of its ability to store, process, and analyze thousands of terabytes of data. A major issue for supporting high performance on Hadoop is managing the growth of data while satisfying high storage I/O request. Hadoop's overall performance is largely influenced by the storage input/output(I/O). However, storage I/O technologies are still very limited. Therefore, now more than ever, studies on improving storage I/O on a distributed file system of Hadoop(HDFS) have been gaining popularity. To this end, latest trend in storage systems is to utilize hybrid storage devices. However, it is not easy to use the information of heterogeneous storage devices in HDFS. This is because, when reading data, HDFS is unable to exploit such heterogeneous storage type information yet. In this paper, we propose a hybrid block-selection method on the HDFS, we consider the storage type such as SSD and HDD when reading data. Using this method, the Hadoop Eco System utilizes the high SSD bandwidth by priority. As a result, we certainly improve the Hadoop Eco System overall performance. In the experiments, we demonstrated that our new method efficiently reduced the execution time of select count(*) query and TPC H benchmark up to 22% and 30% on average.
Longer breastfeeding duration among gifted students in Saudi Arabia

Background: Investigating the factors related to the development of intelligence may improve our understanding of human development. The long-term benefit of breastfeeding on children's intelligence has attracted a great deal of research attention; therefore, the aim of this study was to describe the pattern of breastfeeding among gifted students at the Mawhiba Foundation in Saudi Arabia. Methods: A descriptive cross-sectional survey was conducted using the Mawhiba Foundation database of gifted students in Saudi Arabia. An electronic close-ended questionnaire was circulated to mothers of talented students in Grades 4 and 7 from different regions of Saudi Arabia. Sociodemographic data and the breastfeeding history of each talented student were collected. The main outcome measures were the categories of breastfeeding (breastfeeding, partial/mixed breastfeeding, and never breastfed) and duration of breastfeeding (6 months, 12 months, 18 months, and 2 years) and their association with demographic variables. Results: Of the 233 gifted students enrolled in the study, 214 (91%) were from populous areas in the Eastern, Makkah, and Riyadh regions of Saudi Arabia. The parents of most of these students were educated to the university level or higher (mothers, 192 [82.2%] and fathers, 158 [79.8%]), and almost half of the mothers were employed. The partial/mixed breastfeeding category was the most common observed in this population (171 [73%]). Almost half of the population (91 [41%]) had been breastfed for >1 year. The duration of breastfeeding and the mother's employment status had statistically significant relationships with the breastfeeding categories (P = 0.001 and 0.004, respectively). Conclusions: Partial/mixed breastfeeding is the most common category of breastfeeding, with a tendency toward prolonged breastfeeding among gifted students.
[Attitudes, self-efficacy and intention towards tobacco cessation in Spanish college students].

BACKGROUND To determine attitudes towards smoking, perception of self-efficacy, and the intention of smoking cessation in college student smokers, and their variation according to the stage of the tobacco cessation process. METHODS Cross-sectional study with 255 college students (18-24 years old) smokers of =1 cigarette per week. Instruments used: a personal interview, Fageström test, trans-theoretical change model, scale of Attitudes, self-efficacy and intention to quit smoking in college smokers and CO in exhaled air. RESULTS Sample with a majority of women (62%), average age 20.3 years, users of 9.2 cigarettes/day for 5.7 years, with mild dependence on nicotine; 69% were in the stages of pre-contemplation and contemplation. Although smoking was considered to be negative for health and the environment for more than 70%, and 96.7% had negative attitudes towards tobacco, only 45.1% were aware of the associated morbidity and mortality. More than 60% considered tobacco to be a social facilitator, thus anxiety (72.6%) and having friends who smoke (69.4%) are factors considered negative for tobacco cessation. Ninety-one percent believed that they would smoke next year, but 86% stated that they would not be a smoker within five years. One hundred percent of the subjects in pre-contemplation considered that they will smoke during the next year as opposed to 83.5% of those in the stage of preparation. CONCLUSION College student smokers show positive attitudes, erroneous beliefs and a low perception of self-efficacy about smoking cessation. All students in the pre-contemplation phase do not even consider smoking cessation in the medium and long term.
Fiducial Facial Point Extraction Using a Novel Projective Invariant

Automatic extraction of fiducial facial points is one of the key steps to face tracking, recognition, and animation. Great facial variations, especially pose or viewpoint changes, typically degrade the performance of classical methods. Recent learning or regression-based approaches highly rely on the availability of a training set that covers facial variations as wide as possible. In this paper, we introduce and extend a novel projective invariant, named the characteristic number (CN), which unifies the collinearity, cross ratio, and geometrical characteristics given by more (6) points. We derive strong shape priors from CN statistics on a moderate size (515) of frontal upright faces in order to characterize the intrinsic geometries shared by human faces. We combine these shape priors with simple appearance based constraints, e.g., texture, edge, and corner, into a quadratic optimization. Thereafter, the solution to facial point extraction can be found by the standard gradient descent. The inclusion of these shape priors renders the robustness to pose changes owing to their invariance to projective transformations. Extensive experiments on the Labeled Faces in the Wild, Labeled Face Parts in the Wild and Helen database, and cross-set faces with various changes demonstrate the effectiveness of the CN-based shape priors compared with the state of the art.
Context aided fusion procedure for road safety application

Road safety applications require the most reliable and trustable sensors. Context information plays also a key role, adding trustability and allowing the study of the interactions and the danger inherent to them. Vehicle dynamics, dimensions. can be very useful to avoid misdetections when performing vehicle detection and tracking (fusion levels 0 and 1). Traffic safety information is mandatory for fusion levels 2 and 3 by evaluating the interactions and the danger involved in any detection. All this information is context information that was used in this application to enhance the capacity of the sensors, providing a complete and multilevel fusion application. Present application use three sensors: laser scanner, computer vision and inertial system, the information given by these sensors is completed with context information, providing reliable vehicle detection and danger evaluation. Test results are provided to check the usability of the detection algorithm.
The Spawns of Creative Behavior in Team Sports: A Creativity Developmental Framework

Developing creativity in team sports players is becoming an increasing focus in sports sciences. The Creativity Developmental Framework is presented to provide an updated science based background. This Framework describes five incremental creative stages (beginner, explorer, illuminati, creator, and rise) and combines them into multidisciplinary approaches embodied in creative assumptions. In the first training stages, the emphasis is placed on the enrollment in diversification, deliberate play and physical literacy approaches grounded in nonlinear pedagogies. These approaches allow more freedom to discover different movement patterns increasing the likelihood of emerging novel, adaptive and functional solutions. In the later stages, the progressive specialization in sports and the differential learning commitment are extremely important to push the limits of the creative progress at higher levels of performance by increasing the range of skills configurations. Notwithstanding, during all developmental stages the teaching games for understanding, a game-centered approach, linked with the constraints-led approach play an important role to boost the tactical creative behavior. Both perspectives might encourage players to explore all actions possibilities (improving divergent thinking) and prevents the standardization in their actions. Overall, considering the aforementioned practice conditions the Creativity Developmental Framework scrutinizes the main directions that lead to a long-term improvement of the creative behavior in team sports. Nevertheless, this framework should be seen as a work in progress to be later used as the paramount reference in creativity training.
Prognostic significance of nucleophosmin mutations and FLT3 internal tandem duplication in adult patients with cytogenetically normal acute myeloid leukemia

Background Nucleophosmin (NPM1) gene and fms-like tyrosine kinase 3 gene-internal tandem duplication (FLT3-ITD) mutations are the most frequent mutations in patients with cytogenetically normal (CN)-AML. We analyzed the prognostic impact of these mutations and their interactions in adults with CN-AML. Methods NPM1 mutation (NPM1mut) and FLT3-ITD mutation (FLT3-ITD+) were analyzed by GeneScan and PCR assays of bone marrow samples obtained from 121 adult patients with CN-AML (age≤60 years at diagnosis). Results The incidence of FLT3-ITD+ was higher in the NPM1mut group than in the wild-type NPM1 gene (NPM1wt) group. The patients were divided according to their mutation status into the NPM1mut/FLT3-ITD (isolated NPM1mut), NPM1mut/FLT3-ITD+ or NPM1wt/FLT3-ITD-, and NPM1wt/FLT3-ITD+ (isolated FLT3-ITD+) groups. The isolated NPM1mut group showed significantly better clinical outcomes in terms of relapse rate, 5-year relapse-free survival (RFS), and overall survival (OS) than the other groups. In contrast, the isolated FLT3-ITD+ group had a higher relapse rate and shorter RFS and OS than the other groups. The 5-year RFS rate was much higher among the patients who underwent allogeneic stem cell transplantation (alloSCT) than among those treated with high-dose cytarabine chemotherapy (HDAC) only as consolidation therapy in the isolated NPM1mut group and the NPM1mut/FLT3-ITD+ or NPM1wt/FLT3-ITD- group. Conclusion Adult patients with CN-AML carrying isolated NPM1mut and isolated FLT3-ITD+ exhibit different clinical outcomes than those with NPM1mut/FLT3-ITD+ or NPM1wt/FLT3-ITD-. Although isolated NPM1mut leads to favorable clinical outcomes of CN-AML, the role of alloSCT in such patients remains to be considered.
Nursing Within Primary Care Settings in Atlantic Canada: A Scoping Review

To address the prevalence of chronic diseases in Newfoundland and Labrador, the province has committed to primary health care reform, including implementing interdisciplinary primary care (PC) teams. To inform discussions regarding integrating nurse practitioners (NPs), registered nurses (RNs), and licensed practical nurses (LPNs) into these teams, better understanding of their roles in PC is needed. A scoping review was conducted to examine and synthesize existing evidence related to nursing roles and resources in PC settings across Atlantic Canada (Newfoundland and Labrador, New Brunswick, Nova Scotia, Prince Edward Island), and associated contributions to patient care. Joanna Briggs Institute scoping review methodology was used. The Nursing Role Effectiveness Model guided the review. Twenty articles met inclusion criteria. Roles of RNs and NPs in PC included chronic disease management, education, and health promotion. No literature focused on LPNs. Interdisciplinary collaboration was evident across studies. However, nurses’ functions within teams were limited by institutional constraints and other providers. PC settings with nurses had positive clinical outcomes, improved access to services, and high patient satisfaction. The prevalence of nursing in PC throughout Atlantic Canada and how nurses’ roles are enacted is unclear. There is opportunity for future inquiry into specific attributes of nursing and PC teams that result in positive patient and system outcomes.
Effects of nonsphericity on mineral dust modeling

[1] The dependency of nonsphericity on gravitational settling of mineral dust particles is parameterized for prolate ellipsoids and Reynolds number lower than 2. The settling speed is numerically solved from the momentum equation as a function of particle diameter and aspect ratio. The reduction of settling speed due to nonsphericity is included in the Global Ozone Chemistry Aerosol Radiation and Transport (GOCART) model to simulate dust size distribution for April 2001. Two numerical schemes for solving sedimentation are compared. For particles of diameter greater than 5 μm, the simulated size distribution is sensitive to the numerical sedimentation scheme. Changing the particle shape from spherical to nonspherical with λ = 2 makes little difference to the simulated surface concentration and size distribution except at the periphery of the dust sources. However, when very elongated particles (λ = 5) are simulated, the differences between nonspherical and spherical particles are significant. With limited in situ measurements reporting most frequent λ around 1.5, the overall effects on global modeling is rather negligible and the essential benefit is to relax the CFL condition of Eulerian settling schemes.
Differential recruitment efficacy of patient-derived amyloidogenic and myeloma light chain proteins by synthetic fibrils—A metric for predicting amyloid propensity

Background Monoclonal free light chain (LC) proteins are present in the circulation of patients with immunoproliferative disorders such as light chain (AL) amyloidosis and multiple myeloma (MM). Light chain-associated amyloid is a complex pathology composed of proteinaceous fibrils and extracellular matrix proteins found in all patients with AL and in ~10–30% of patients who presented with MM. Amyloid deposits systemically in multiple organs and tissues leading to dysfunction and ultimately death. The overall survival of patients with amyloidosis is worse than for those with early stage MM. Methods and findings We have developed a sensitive binding assay quantifying the recruitment of full length, patient-derived LC proteins by synthetic amyloid fibrils, as a method for studying their amyloidogenic potential. In a survey of eight urinary LC, both AL and MM-associated proteins were recruited by synthetic amyloid fibrils; however, AL-associated LC bound significantly more efficiently (p < 0.05) than did MM LCs. The LC proteins used in this study were isolated from urine and presumed to represent a surrogate of serum free light chains. Conclusion The binding of LC to synthetic fibrils in this assay accurately differentiated LC with amyloidogenic propensity from MM LC that were not associated with clinical amyloid disease. Notably, the LC from a MM patient who subsequently developed amyloid behaved as an AL-associated protein in the assay, indicating the possibility for identifying MM patients at risk for developing amyloidosis based on the light chain recruitment efficacy. With this information, at risk patients can be monitored more closely for the development of amyloidosis, allowing timely administration of novel, amyloid-directed immunotherapies—this approach may improve the prognosis for these patients.
The paradoxical influence of stress on the intensity of romantic feelings towards the partner

According to Brehm’s emotional intensity theory (EIT), the strength of feelings of romantic affect towards a romantic partner should vary as a cubic function of increasing levels of relationship stress (i.e., deterrence to feelings of romantic affect). The study tested this hypothesis in a true experiment with 80 young adults actually engaged in a romantic relationship, by systematically manipulating stress, through a recall procedure, across four distinct levels of intensity (control vs. low vs. moderate vs. high levels of manipulated stress). As predicted by emotional intensity theory, feelings of romantic affect were strong in the control condition, reduced in the low stress condition (low deterrence), maintained intense in the moderate stress condition (moderate deterrence), and reduced, again, in the high stress condition (high deterrence). Findings and both theoretical and practical implications for professionals and future research are discussed, with special emphasis on how to promote partners’ everyday adjustments to stress and emotional intensity regulation.
Compton reflection and iron fluorescence in BeppoSAX observations of Seyfert type 1 galaxies

A sample of nine bright Seyfert 1 and NELG type galaxies, observed with BeppoSAX, is analyzed to assess on a truly broad band basis (0.1{200 keV) the issue of the spectral contributions of Compton reflection and iron line fluorescence from circumnuclear gas. The empirical description adopted for the direct continuum is the commonly used power law with an exponential cut{o. The most direct test of the theoretical predictions, namely that the equivalent width of the line, W, and the strength R of the reflection relative to the direct continuum are closely related to each other, gives a substantially positive result, that is their mean ratio is very close to expectation, and only a modest spread in the iron abundance seems implied. The existence of a steep correlation between R and the slope of the power law is not conrmed. A weak evidence is found that the existence of a very shallow trend to increase on average with cannot be altogether excluded in both R and W, but needs to be tested with a larger sample. The energy Ef in the exponential cut{o spans a range from about 80 to more than 300 keV. A possible correlation is found, with Ef increasing on average with : if ignored, for instance by keeping Ef at a xed value in a sample study, it could be cause of articial steepening in a correlation between R and .
An intonational study of Kuwaiti Bedouin Arabic

The present study deals with the intonation of Kuwaiti Bedouin Arabic (KBA). This is the product of an earlier Central Arabian intonation type which is yielding to the speech patterns of the majority of the population. It does not contrast very extensively with standard Kuwaiti. The main intonation systems of the dialect are shown and illustrated. Some indication is given of what intonations are dying out and what usages have survived and reasons are suggested for why they have survived. Chapter One traces the background of the people, their origin and settlement patterns. Reading conventions and the method of indicating intonation are provided. Chapter Two reviews what has been said in the literature, and treats the most relevant work in English and Arabic. Chapter Three shows the intonation patterns of KBA, their contours and what they communicate. Some visible intonation contour traces from a speech meter are included. Chapter Four exhibits the sentence types distinguished by intonation, and shows what tones go with what kind of sentence. Since attitude is diffused in the system and no single utterance can be said to be without emotion, attitude becomes a very difficult factor to contrast in the analysis, because one cannot fix exact emotions that go with specific tones. However, the writer tries to deal with the situations in which the particular utterance is associated with specific tones. Chapter Five provides three main models that intonation can display according to Kalliday's well known contrastive categories, which are tonality, tonicity and tone, to show how speakers manipulate their intonation patterns to fit their communication needs. Chapter Six ends with a short summary to pinpoint the main findings in the thesis. The appendix consists of some texts of different topics and their translations.
Compatibility of prior specifications across linear models

Bayesian model comparison requires the specification of a prior distribution on the parameter space of each candidate model. In this connection two concerns arise: on the one hand the elicitation task rapidly becomes prohibitive as the number of models increases; on the other hand numerous prior specifications can only exacerbate the well-known sensitivity to prior assignments, thus producing less dependable conclusions. Within the subjective framework, both difficulties can be counteracted by linking priors across models in order to achieve simplification and compatibility; we discuss links with related objective approaches. Given an encompassing, or full, model together with a prior on its parameter space, we review and summarize a few procedures for deriving priors under a submodel, namely marginalization, conditioning, and Kullback--Leibler projection. These techniques are illustrated and discussed with reference to variable selection in linear models adopting a conventional $g$-prior; comparisons with existing standard approaches are provided. Finally, the relative merits of each procedure are evaluated through simulated and real data sets.
Bimeromorphic automorphism groups of non-projective hyperkähler manifolds—a note inspired by C.T. McMullen

Being inspired by a work of Curtis T. McMullen about a very impressive automorphism of a K3 surface of Picard number zero, we shall clarify the structure of the bimeromorphic automorphism group of a non-projective hyperk\"ahler manifold, up to finite group factor. We also discuss relevant topics, especially, new counterexamples of Kodaira's problem about algebraic approximation of a compact K\"ahler manifold.
MBD4 Interacts With and Recruits USP7 to Heterochromatic Foci

MBD4 is the only methyl‐CpG binding protein that possesses a C‐terminal glycosylase domain. It has been associated with a number of nuclear pathways including DNA repair, DNA damage response, the initiation of apoptosis, transcriptional repression, and DNA demethylation. However, the precise contribution of MBD4 to these processes in development and relevant diseases remains elusive. We identified UHRF1 and USP7 as two new interaction partners for MBD4. Both UHRF1, a E3 ubiquitin ligase, and USP7, a de‐ubiquinating enzyme, regulate the stability of the DNA maintenance methyltransferase, Dnmt1. The ability of MBD4 to directly interact with and recruit USP7 to chromocenters implicates it as an additional factor that can potentially regulate Dnmt1 activity during cell proliferation. J. Cell.

Validating Uncertainty Analyses for Gas Flow Standards via Intra- and Inter-Laboratory Comparisons

The Fluid Flow Group (FFG) at NESTmaintains flow standards to perform calibrations of gas flowmeters over the 3.7x 10-2L/rein@to 78,000 L/rein flow range. Uncertainty analyses based on the propagation of uncertainties method show that the uncertainties of the provers range from O.16’%o to O.19’? 40. The results of inter-laboratory comparisons and intra-laboratory comparisons (i.e., “crossover tests” between two different provers within the NIST laboratory) are examined to verify the uncertainty analysis results. The concepts of shortand Iong-term crossover tests and comparison tolerance are discussed. The comparison test results support the uncertainty specifications for the FFG gas flow standards.
