Statistical analysis of wave parameters in the north coast of the Persian Gulf

Abstract. In this study we have analysed wind and wave time series data resulting from hourly measurements on the sea surface in Bushehr, the northern part of the Persian Gulf, from 15 July to 4 August 2000. Wind speed (U10) ranged from 0.34 to 10.38 m/s as alternating sea and land breezes. The lowest wind speed occurs at about midnight and the highest at around noon. The calculated autocorrelation of wind speed data shows that when the sea-land breeze is strong, the land-sea breeze is weak and vice versa. The significant wave height (Hs) varies between 0.10 to 1.02 m. The data of the present study reflects mostly the local waves or the sea waves. The calculated correlation between wind and wave parameters is rather weak, due to the continuous change in the wind direction. Wave height distribution follows the well-known Rayleigh distribution law. The cross correlation analyses between U10 and Hs reveal a time lag of 4h. Finally, we have shown that the time series of U10, Hs, and wave period are stationary. We have modeled these parameters by an auto regressive moving average (ARMA) and auto regressive integrated moving average (ARIMA) models. Keywords.

Clinical significance of the BCR-ABL fusion gene in adult acute lymphoblastic leukemia: a Cancer and Leukemia Group B Study (8762).

The Philadelphia (Ph1) chromosome, or its molecular counterpart, the BCR-ABL fusion gene, is a rare but important prognostic indicator in childhood acute lymphoblastic leukemia (ALL), but its impact on adult ALL has not been well ascertained. A prospective study of the BCR-ABL fusion gene was begun on patients entered on clinical trials conducted by the Cancer and Leukemia Group B (CALGB). All patients received intensive, multiagent chemotherapy that included daunorubicin. Over 2 years, 56 patients were studied for molecular evidence of a BCR-ABL gene using Southern blot and pulsed-field gel hybridization analysis. Results were compared with cytogenetic detection of a Ph1 chromosome, and clinical features were compared for the BCR-ABL-positive and -negative groups. Molecular methods detected the BCR-ABL gene in 30% of cases compared with cytogenetic detection of the Ph1 chromosome in only 23%. The majority of cases (76%) showed the p190 gene subtype similar to pediatric ALL; the BCR-ABL-positive cases displayed a more homogeneous immunophenotype than the BCR-ABL-negative cases and were predominantly CALLA positive (86%) and B-cell surface antigen positive (82%). The rate of achieving complete remission was similar in the BCR-ABL-positive and -negative groups (71% and 77%, respectively, P = .72). There were more early relapses in the BCR-ABL-positive group, resulting in a shorter remission duration that was especially marked in the CALLA-positive and B-cell antigen-positive populations. These preliminary data suggest that the impact of the BCR-ABL gene on clinical outcome in ALL may be on maintenance of complete remission (CR) rather than achievement of CR when aggressive, multiagent chemotherapy is used. This study identifies the BCR-ABL gene as an important factor in adult ALL and demonstrates the utility of molecular methods for its accurate diagnosis.
Influencing factors of transient elastography in detecting liver stiffness

Liver stiffness, which correlates well with liver fibrosis stage, can be measured noninvasively by transient elastography, also known as Fibroscan. The present study aimed to determine the independent factors influencing Fibroscan detection by multiple regression analysis. A total of 181 patients who required liver biopsy were enrolled. Liver stiffness measurement (LSM) was detected by Fibroscan on the day of liver biopsy, while clinical information and routine biochemical examination results were also collected. Correlation was analyzed by Spearman's correlation, and multiple regression analysis was performed to analyze the independent influencing factors. The results demonstrated that platelet (PLT) levels, serum albumin (ALB), prothrombin activity (PTA) and body mass index (BMI) were independent predictors of liver stiffness. The contribution of these four predictors to the regression equation was in the following descending order: PLT (negative correlation) > ALB (negative correlation) > PTA (negative correlation) > BMI (positive correlation). In conclusion, the parameters of PLT, ALB, PTA and BMI are independent predicting factors affecting Fibroscan detection. Therefore, the diagnosis and evaluation of liver fibrosis should comprehensively consider the results of Fibroscan, and clinical and laboratory examinations.
Learning biology as ‘Increase ones’ knowledge and understanding’: studying Taiwanese high school students’ learning strategies in relation to their epistemic views and conceptions of learning in biology

ABSTRACT This study aimed to examine high school students’ learning strategies in relation to their epistemic views and conceptions of learning in the discipline of biology through a structural equation modelling technique. A total of 247 high school students (168 males) participating in this study completed 3 questionnaires, the Epistemic Views of Biology (EVB), the Conceptions of Learning Biology (COLB), and the Strategies of Learning Biology (SLB). The results supported the hypothesised model proposed in this study, and a new factor of ‘Increase one’s Knowledge and Understanding,’ reflecting the feature of high school students’ biology learning, and serving an important role in biology learning, was identified in this study. In addition, students’ epistemic views were associated with their conceptions of learning, which consequently correlated to their learning strategies. More specifically, the EVB of ‘Uncertainty’ negatively related to lower COLB, which consequently positively related to Surface Strategies, whereas the EVB of ‘Justification’ was positively correlated to higher COLB as ‘Increase one’s Knowledge and Understanding,’ which in turn was correlated to Deep Strategies. According to the research findings, theoretical and practical suggestions for future research are provided.
Prediction of course completion by students of a university in Brazil

Abstract The conclusion of the undergraduate course by university students in the time predicted by the curriculum is desirable for young people and for society. The aim was to verify the reliability, sensitivity and specificity of a broad set of predictors for academic performance of university students, who completed the undergraduate course within the time predicted by the curricula, through data mining methodology, provided by the Support Vector Machines algorithm. A simple approach is proposed for the prediction of course completion by students in a university in Brazil. The dataset has 170 students who finished the course and 117 who did not finish. With the proposed methodology, it was possible to predict the course completion by students with an accuracy of 79.5% when using the 19 original variables. An accuracy of 75% was found using only 05 variables: Course, year of the course, gender, initial and final academic performance.
Chromosomal Abnormalities in Reimplantation Development

Direct testing of the outcome of human female meiosis demonstrated that up over a half of oocytes from IVF patients of advanced reproductive age are aneuploid, originating comparably from meiosis I and meiosis II errors, with potential probability of aneuploidy rescue in an almost half of oocytes with sequential first and second meiotic errors. One fifth of abnormalities originating from meiosis I and II are of complex nature, with nonrandom distribution of chrmomatid/chromosome (10:1 ratio), and missing/extra chromotid (chromosome) errors (2:1 ratio). The data also demonstrate the relationship between embryo viability and meiotic origin of chromosomal errors, affecting their clinical impact on preimplantation and post-implantation development
Variables That Best Differentiate In-Patient Acute Stroke from Stroke-Mimics with Acute Neurological Deficits

Introduction. Strokes and stroke-mimics have been extensively studied in the emergency department setting. Although in-hospital strokes are less studied in comparison to strokes in the emergency department, they are a source of significant direct and indirect costs. Differentiating in-hospital strokes from stroke-mimics is important. Thus, our study aimed to identify variables that can differentiate in-hospital strokes from stroke-mimics. Methods. We present here a retrospective analysis of 93 patients over a one-year period (2009 to 2010), who were evaluated for a concern of in-hospital strokes. Results. About two-thirds (57) of these patients were determined to have a stroke, and the remaining (36) were stroke-mimics. Patients with in-hospital strokes were more likely to be obese (p = 0.03), have been admitted to the cardiology service (p = 0.01), have atrial fibrillation (p = 0.03), have a weak hand or hemiparesis (p = 0.03), and have a prior history of stroke (p = 0.05), whereas, when the consults were called for “altered mental status” but no other deficits (p < 0.0001), it is likely a stroke-mimic. Conclusion. This study demonstrates that in-hospital strokes are a common occurrence, and knowing the variables can aid in their timely diagnosis and treatment.
Are Cognitive Symptoms of Schizophrenia Mediated by Abnormalities in Emotional Arousal?

ABSTRACT We tested 28 individuals with schizophrenia (SZ) and 16 healthy individuals on a test of logical reasoning and “cognitive gating,” defined as the ability to discriminate between relevant and irrelevant information in confirming or disconfirming a given belief. The Logical Reasoning and Cognitive Gating Task tests both processes under neutral and affect-laden conditions. This is done by presenting formally identical constructs using benign and emotionally arousing language. When separated by symptom profiles, we found statistically significant differences for performance and arousal response between patients with delusions, patients with formal thought disorder, and patients with neither delusions nor formal thought disorder, as well as between patients and healthy controls. When analyzed by error type, we found that nearly all errors by delusional patients were caused by overly restrictive information choice, a pattern that may be related to a delusional patient's tendency to “jump to conclusions” on Bayesian probabilistic tasks. This is in contrast to patients with formal thought disorder, whose low performance resulted also from overly extensive information choice. The tendencies towards restriction were exacerbated by arousal, which is consistent with studies on cognition and arousal in healthy individuals. After briefly examining research on emotional arousal and SZ, and the interaction between emotional arousal and restriction of perceptual cues in healthy individuals, we conclude by suggesting a model which accounts for the distinctive cognitive characteristics of delusional patients by their possessing distinct vulnerabilities to emotional arousal. Specifically, these results suggest the possibility that delusional patients process information in a manner that is essentially intact. However, delusional patients may possess an acute vulnerability to emotional arousal that might cause delusional individuals to behave cognitively as if they were healthy individuals under significantly more severe forms of stress.
Clostridium difficile Infections amongst Patients with Haematological Malignancies: A Data Linkage Study

Objectives Identify risk factors for Clostridium difficile infection (CDI) and assess CDI outcomes among Australian patients with a haematological malignancy. Methods A retrospective cohort study involving all patients admitted to hospitals in Western Australia with a haematological malignancy from July 2011 to June 2012. Hospital admission data were linked with all hospital investigated CDI case data. Potential risk factors were assessed by logistic regression. The risk of death within 60 and 90 days of CDI was assessed by Cox Proportional Hazards regression. Results There were 2085 patients of whom 65 had at least one CDI. Twenty percent of CDI cases were either community-acquired, indeterminate source or had only single-day admissions in the 28 days prior to CDI. Using logistic regression, having acute lymphocytic leukaemia, neutropenia and having had bacterial pneumonia or another bacterial infection were associated with CDI. CDI was associated with an increased risk of death within 60 and 90 days post CDI, but only two deaths had CDI recorded as an antecedent factor. Ribotyping information was available for 33 of the 65 CDIs. There were 19 different ribotypes identified. Conclusions Neutropenia was strongly associated with CDI. While having CDI is a risk factor for death, in many cases it may not be a direct contributor to death but may reflect patients having higher morbidity. A wide variety of C. difficile ribotypes were found and community-acquired infection may be under-estimated in these patients.
Nitrilase 1 modulates lung tumor progression in vitro and in vivo

Uncovering novel growth modulators for non-small cell lung cancer (NSCLC) may lead to new therapies for these patients. Previous studies suggest Nit1 suppresses chemically induced carcinogenesis of the foregut in a mouse model. In this study we aimed to determine the role of Nit1 in a transgenic mouse lung cancer model driven by a G12D Kras mutation. Nit1 knockout mice (Nit1−/−) were crossed with KrasG12D/+ mice to investigate whether a G12D Kras mutation and Nit1 inactivation interact to promote or inhibit the development of NSCLC. We found that lung tumorigenesis was suppressed in the Nit1-null background (Nit1−/−:KrasG12D/+). Micro-CT scans and gross tumor measurements demonstrated a 5-fold reduction in total tumor volumes compared to Nit1+/+KrasG12D/+ (p<0.01). Furthermore, we found that Nit1 is highly expressed in human lung cancer tissues and cell lines and use of siRNA against Nit1 decreased overall cell survival of lung cancer cells in culture. In addition, cisplatin response was enhanced in human lung cancer cells when Nit1 was knocked down and Nit1−/−:KrasG12D/+ tumors showed increased sensitivity to cisplatin in vivo. Together, our data indicate that Nit1 may play a supportive role in the modulation of lung tumorigenesis and represent a novel target for NSCLCs treatment.
Exact solutions of the radial Schrödinger equation for some physical potentials

By using an ansatz for the eigenfunction, we have obtained the exact analytical solutions of the radial Schrödinger equation for the pseudoharmonic and the Kratzer potentials in two dimensions. The bound-state solutions are easily calculated from this eigenfunction ansatz. The corresponding normalized wavefunctions are also obtained.
Improved lower bounds on the connective constants for two-dimensional self-avoiding walks

We calculate improved lower bounds for the connective constants for self-avoiding walks on the square, hexagonal, triangular, (4.82) and (3.122) lattices. The bound is found by Kesten's method of irreducible bridges. This involves using transfer-matrix techniques to exactly enumerate the number of bridges of a given span to very many steps. Upper bounds are obtained from recent exact enumeration data for the number of self-avoiding walks and compared to current best available upper bounds from other methods.
Ordinal Structure of the Generic Analytic Workflow: A Survey of Intelligence Analysts

We present a model of the generic analytic workflow and measure the extent of ordinal structure that analysts apply to analytic work, as well as how this is affected by their training and experiences. The workflow comprises six stages that follow from one another: capture requirements, plan analytic response, obtain data, process data, interpret outputs, and communicate conclusions. A survey of 144 intelligence analysts revealed that only 16% structured their workflows in a logical ordinal way. The extent of ordinal structure applied to analytic work was unrelated to analytic thinking training, years of analytic experience, and proportion of time spent working collaboratively. These findings have implications for the training and assessment of analysts, as well as for the design of analytic tools.
The Albedo Distribution of Jovian Trojan Asteroids

We present radiometrically derived V-band geometric albedos and effective radii for 32 Jovian Trojan asteroids, using near-simultaneous mid-infrared and visible observations. We sampled the large end of the group's size distribution, down to a radius of 25 km, using 14 objects in the L4 swarm and 18 in the L5 swarm. We find that the albedo distribution is much narrower than previously derived from IRAS measurements. The Trojans, for the most part, have very similar albedos. The actual mean and standard deviation of the distribution depend on the average Trojan beaming parameter η. The "standard" value of 0.756, which was used for the IRAS analysis, yields a mean albedo of 0.056 ± 0.003 and a standard deviation of 0.009. However, a value of η = 0.94, which we found represented our data better, yields 0.041 ± 0.002 and a standard deviation of just 0.007. The thermal behavior of the Trojans seems to follow the "slow rotator" model, and the thermal inertia itself can be no greater than about half the Moon's value. The Kolmogorov-Smirnov test was used to compare the Trojans' albedo distribution with that of cometary nuclei, dead-comet candidates, and outer solar system objects. We find that the Trojan distribution is similar only to the cometary ones, and only if the Trojans' η ≈ 1. Observations of the binary (617) Patroclus reveal that its albedo is rather typical among the distribution. We have also discovered that (4709) Ennomos has an extremely elevated albedo, about 0.15. This object may have a very unusual thermal behavior or have recently suffered a large impact that excavated the surface down to a layer of highly reflective, pristine ice.
Emotion regulation and its relationship to academic difficulties among Jordanian first grade students

ABSTRACT The purpose of this study is to examine the relationship between emotion regulation and academic difficulties among 367 Jordanian first grade students. Two measurements were applied: The Conners Comprehensive Behaviour Rating Scales and the Emotion Regulation Checklist. The study results revealed a statistically significant inverse correlation between male and female first grade students’ academic difficulties and their ability to regulate emotions. The weaker the ability of first grade students to organize their emotions, the greater the likelihood of facing academic difficulties. The results also indicated the presence of apparent differences in the correlation coefficients attributed to gender in favour of male students, as emotion regulation impacted academic difficulties in male students to a higher degree than the impact in female students. Finally, the results suggested a predictive relationship between students’ emotion regulation skills and level of academic difficulties.
Design and implementation of automatic defensive websites tamper-resistant based on OpenStack cloud system

With the popularity of Internet applications, security issues of Web become increasingly prominent. The tampering contents and embedding Trojan in public Internet website will seriously affect the public image of the government and enterprises, and result in significant economic losses and adverse social impact. To solve the above problems, we researched and developed a Web tamper-resistant system that have the characteristics of fast response, accurate judgment and flexible deploy. Cloud storage platform could provide redundant data object storage with the advantages of high durability, completely symmetrical system architecture, unlimited scalability and no single point of failure. To improve the robustness and security of tamper-proof system, we built a Cloud storage environment based on the OpenStack open source Cloud computing platform to design and implement a website anti-tamper system in Cloud environment. The Implementation of the system will help to maintain the website environmental security of the public Internet to ensure the protection of the website information and critical network information systems.
The Influence of Anger on Strategic Cooperative Interactions

We investigate the effect of anger on performance and strategic cooperative interactions. In a laboratory experiment, we induced anger in participants playing an indefinite repeated Prisoner’s Dilemma game against each other, showing resulting declines in performance and individual profit. We assess the dynamics of strategic cooperative decisions and behaviors, revealing that anger-induced subjects used suboptimal strategies. We further describe the underpinning mechanism of automatic emotional regulation by analyzing participants’ heart rate variability indexes. Finally, we extend our findings in an online experiment with an independent sample, increasing generalizability and helping explain how anger influences participants’ ways of strategizing. Altogether, our contribution advances theoretical and practical implications regarding the impact of discrete emotions on strategic outcomes.
Factors affecting performance in first-year computing

Performances are analysed over successive semesters for a cohort of first-year students doing computer programming. Attainment is related to performance in other studies. However, many factors have roles. Learning style and problem-solving skills are important in information technology in Semester I. Gender and secondary school outcomes matter in introductory programming, also in Semester I. Dislike of programming influences outcomes in introductory programming and in Data Structures and Algorithms in Semester II. For a number of indicators, influence fluctuates over time and across area of study.
A dyadic model of investments: Partner effects on commitment

A dyadic approach to studying relationship dynamics yields considerably more insights than examining each partner separately. Yet relatively little research has examined dyadic models of commitment, despite commitment being essential to relationship persistence. Accordingly, we tested a dyadic version of the investment model of commitment. In two cross-sectional studies of couples and one experiment, we tested the role of partner investments and perceived partner investments as novel antecedents of commitment. Studies 1 and 2 demonstrated that greater partner investments were related to greater levels of individuals’ commitment, while controlling for individuals’ own satisfaction with, investments in, and alternatives to the relationship. Study 3 revealed that partner-reported investments predicted commitment independent of perceived partner investments. The findings advance the investment model beyond the individual level, emphasizing the need to examine dyadic elements of relationships.
Anomalous Transport: A Mathematical Framework

We develop a mathematical framework allowing to study anomalous transport in homogeneous solids. The main tools characterizing the anomalous transport properties are spectral and diffusion exponents associated to the covariant Hamiltonians describing these media. The diffusion exponents characterize the spectral measures entering in Kubo's formula for the conductivity and hence lead to anomalies in Drude's formula. We give several formulas allowing to calculate these exponents and treat, as an example, Wegner's n-orbital model as well as the Anderson model in coherent potential approximation.
