Radio spectrum of the AXP J1810 197 and of its profile components

As part of a European Pulsar Network (EPN) multitelescope observing campaign, we performed simultaneous multifrequency observations at 1.4, 4.9 and 8.4 GHz during 2006 July and quasi-simultaneous multifrequency observations from 2006 December until 2007 July at 2.7, 4.9, 8.4, 14.6 and 32 GHz, in order to obtain flux density measurements and spectral features of the 5.5 s radio-emitting magnetar AXP J1810−197. We monitored the spectral evolution of its pulse shape which consists of a main pulse (MP) and an interpulse (IP). We present the flux density spectrum of the average profile and of the separate pulse components of this first-known radio-emitting transient anomalous X-ray pulsar. We observe a decrease in the flux density by a factor of 10 within 8 m and follow the disappearance of one of the two main components. Although the spectrum is generally flat, we observe large fluctuations of the spectral index with time. For that reason, we have made some measurements of modulation indices for individual pulses in order to investigate the origin of these fluctuations.
Years of Matter Wave : Louis de Broglie and Renaissance of the Causally Complete Knowledge

A physically real wave associated to any moving particle and propagating in a surrounding material medium was introduced by Louis de Broglie in a series of short notes in 1923 and in the most complete form in his thesis defended in Paris on the 25th November 1924. This result, recognised by the Nobel Prize in 1929, gave rise to the whole field of the ‘new physics’ known today as ‘quantum mechanics’. However, although such notions as ‘de Broglie wavelength’ and ‘wave-particle duality’ have become ‘conventional’ in the standard quantum theory, it actually only takes for granted (postulates) the formula for the wavelength (similar to other its formally postulated ‘results’) and totally ignores the underlying causal, physically real and transparent picture of quantum/wave behaviour outlined by Louis de Broglie in his thesis and further considerably developed in his later works, in the form of ‘double solution’ and ‘hidden thermodynamics’ concepts (the first of them is only mechanistically imitated within the over-simplified ‘interpretation’ of ‘Bohmian mechanics’, now often presented as ‘causal de Broglie-Bohm theory’). The payment for such crude deviation from the basic de Broglian realism is the absolute domination of the fundamental science by purely abstract, detached from reality and mechanistically simplified schemes made of formal symbols and rules that has inevitably led it into the deep impasse judiciously described today as the ‘end of science’. However, an independent approach of the ‘quantum field mechanics’ (quant-ph/9902015,16, gr-qc/9906077) created recently within the ‘universal science of complexity’ and the related ‘dynamic redundance paradigm’ (physics/9806002) leads to confirmation and natural completion of unreduced de Broglie's results eliminating all their ‘difficult points’ and reconstituting the causally complete, totally adequate and naturally unified picture of the objective reality directly extendible to all higher levels of the complex
The Bond Rate and Actual Future Inflation

The long-term bond rate is cointegrated with the actual one-period inflation rate during two sample periods, 1961Q1 to 1979Q3 and 1961Q1 to 1995Q4. This result indicates that in the long run the bond rate and actual inflation move together. The nature of short-run dynamic adjustments between these variables has, however, changed over time. In the pre-1979 period, when the bond rate rose above the one-period inflation rate, actual inflation accelerated. In the post-1979 period, however, the bond rate reverted back and actual inflation did not accelerate. Thus, the bond rate signaled future inflation in the period before 1979, but not thereafter. The results here indicate that in the period after 1979 Fed policy prevented any pickup in inflationary expectations (evidenced by the rise in the bond rate) from getting reflected in higher actual future inflation.
Coupling impedance for modern accelerators

A systematic review of theoretical results for the longitudinal and transverse impedances obtained by different methods is presented. The paper comprises definitions, general theorems, modal analysis, a diffraction model, and analytical results. Several new results are included. In particular, necessary and sufficient conditions are given for the independence of the impedance from the beam longitudinal direction. The impedances of two basic simple structures—that of a cavity and that of a step—are studied in detail. The transition from the regime of a cavity to the regime of a step is explained, an approximate formula describing this transition is given, and the criterion for determining the applicability of each regime is established. The asymptotic behavior of the impedance for a finite number M of periodically arranged cavities as a function of M is studied. The different behaviors of the impedance for a single cavity and that for an infinite number of cavities are explained as resulting from the interference of the diffracted waves. A criterion for determining the transition in the impedance behavior from small M to large M is presented.
Magnetic particle hyperthermia: nanoparticle magnetism and materials development for cancer therapy

Loss processes in magnetic nanoparticles are discussed with respect to optimization of the specific loss power (SLP) for application in tumour hyperthermia. Several types of magnetic iron oxide nanoparticles representative for different preparation methods (wet chemical precipitation, grinding, bacterial synthesis, magnetic size fractionation) are the subject of a comparative study of structural and magnetic properties. Since the specific loss power useful for hyperthermia is restricted by serious limitations of the alternating field amplitude and frequency, the effects of the latter are investigated experimentally in detail. The dependence of the SLP on the mean particle size is studied over a broad size range from superparamagnetic up to multidomain particles, and guidelines for achieving large SLP under the constraints valid for the field parameters are derived. Particles with the mean size of 18 nm having a narrow size distribution proved particularly useful. In particular, very high heating power may be delivered by bacterial magnetosomes, the best sample of which showed nearly 1 kW g−1 at 410 kHz and 10 kA m−1. This value may even be exceeded by metallic magnetic particles, as indicated by measurements on cobalt particles.
Electrokinetic and Hemostatic Profiles of Nonwoven Cellulosic/Synthetic Fiber Blends with Unbleached Cotton

Greige cotton contains waxes and pectin on the outer surface of the fiber that are removed when bleached, but these components present potential wound dressing functionality. Cotton nonwovens blended with hydrophobic and hydrophilic fibers including viscose, polyester, and polypropylene were assessed for clotting activity with thromboelastography (TEG) and thrombin production. Clotting was evaluated based on TEG measurements: R (time to initiation of clot formation), K (time from end of R to a 20 mm clot), α (rate of clot formation according to the angle tangent to the curve as K is reached), and MA (clot strength). TEG values correlate to material surface polarity as measured with electrokinetic parameters (ζplateau, Δζ and swell ratio). The material surface polarity (ζplateau) varied from −22 to −61 mV. K values and thrombin concentrations were found to be inversely proportional to ζplateau with an increase in material hydrophobicity. An increase in the swell ratios of the materials correlated with decreased K values suggesting that clotting rates following fibrin formation increase with increasing material surface area due to swelling. Clot strength (MA) also increased with material hydrophobicity. Structure/function implications from the observed clotting physiology induced by the materials are discussed.
Impact of preventing exacerbations on deterioration of health status in COPD

Exacerbations of chronic obstuctive pulmonary disease (COPD) are associated with worse health status. The Inhaled Steroids in Obstructive Lung Disease in Europe (ISOLDE) study showed that treatment with fluticasone propionate (FP) reduced exacerbation frequency and the rate of deterioration in health status as compared with placebo. The present study analysed these data to test whether the effect of FP on health status was attributable to its effect on exacerbations. Rates of deterioration in St George's Respiratory Questionnaire (SGRQ) total score were obtained for 613 patients with moderate to severe COPD followed for a maximum of 3 yrs. Exacerbation rates were skewed and could not be normalised, therefore, patients were stratified into three exacerbation groups: none, infrequent (<1.65 exacerbations·yr−1) and frequent (>1.65 exacerbations·yr−1). There were 91 patients with no exacerbations, 285 with infrequent exacerbations and 235 with frequent exacerbations. Frequent exacerbations were independently associated with a worse baseline SGRQ score (p<0.0001) and a more rapid rate of deterioration in health status (p=0.0003). Exacerbation frequency and rate of decline in forced expiratory volume in one second were independently related to the rate of deterioration in SGRQ score. Statistical modelling showed the beneficial effect of fluticasone propionate on deterioration in health status to be largely due to its effect on exacerbation frequency.
Reported hypoglycemia in Type 2 diabetes mellitus patients: Prevalence and practices-a hospital-based study

Introduction: Hypoglycemia tops the list of hurdles in preventing tight glycemic control in diabetic patients. It is even considered as a cardiovascular risk factor. However, it continues to be a neglected complication with very limited epidemiological data in our country. Aim: To study the self-reported prevalence of hypoglycemia among type 2 diabetic patients and the practices adopted by them during and after the episodes to manage and avert future occurrences. Materials and Methods: It is a questionnaire-based cross-sectional study done using systematic random sampling selecting every 5th patient attending the diabetic Out-Patient (OP) in a tertiary medical college hospital. Results: There were 366 participants with median age of 60 years. Around 96% reported any one symptom of hypoglycemia, but 78% had eaten following the episode and got relieved of the symptoms. Weakness (76.2%) and dizziness (74%) were the most common symptoms reported by the patients. A quarter of them reported having severe attacks requiring somebody's assistance. Most patients resorted to timely meals (85%) to avert future attacks. Patients who took insulin along with oral hypoglycemic agents (OHAs) were at a higher risk (OR = 2.3) for hypoglycemia compared to patients taking only OHAs (P < 0.01). Conclusion: The reported prevalence of hypoglycemia among type 2 diabetes patients is quite high. This finding reiterates the importance of enquiring and educating every diabetic patient about hypoglycemic episodes during every health visit.
Factors of Job Satisfaction in the Healthcare Industry

The study aims to analyze and explore the factors that affect job satisfaction among nurses working in Emergency Departments. An online questionnaire was implemented to examine the factors that most influence overall job satisfaction among nurses in the Emergency Department. The survey contained items on job characteristics, as well as basic socio-demographics. Based on the results from the quantitative study, nurses working in the Emergency Department have a low overall job satisfaction score, with an average of 2.65 in a scale of 5-point Likert scale. The most influential factors of job satisfaction with significant correlation with the overall job satisfaction is work itself (0.801, p < 0.01) and the relationship with management (0.795, p < 0.01). Socio-demographic factors such as age, gender, level of education and number of children are not significantly influencial on the total score of employee satisfaction. Explore the determinants of job satisfaction nurses in the Emergency Department, highlight its importance in the current situation in Sweden and make recommendations about which are the main determinants of job dissatisfaction that need to be tackle from a managerial perspective. The low job satisfaction should be tackle from the managerial level by: implementing individual evaluation of the job satisfaction among nurses, increase the positive feedback from supervisors, involving experienced workers in the ED to influence in organizational decisions, introducing individual meetings with employees to identify their particular needs, improve the number of human resources by attracting internally contracted employees with compensations for weekends and evening/nights instead of hiring external nurses to cover those shifts.
On the Benefits of QoS-Differentiated Posted Pricing in Cloud Computing: An Analytical Model

When designing service and pricing models, an important goal is to both enable user-friendly and cost-effective access to services and achieve a high system's utilization. Such design could attract more users and improve the revenue. QoS-differentiated pricing represents an important direction to address the above design goal as illustrated by numerous studies in other fields such as Internet. In this paper, we propose the first analytical model of QoS-differentiated posted pricing in the context of cloud computing. In this model, a cloud provider offers a stable set of SLAs and their prices are also posted to users in advance, where higher QoSs are charged higher prices. As a result, users can directly choose their preferred SLA with a certain price, in contrast to many existing dynamic pricing mechanisms with the uncertain prices and availability of cloud resource. In order to maximizing the revenue of a cloud provider, the questions that arise here include: (1) setting the prices properly to direct users to the right SLAs best fitting their need, and, (2) given a fixed cloud capacity, determining how many servers should be assigned to each SLA and which users and how many of their jobs are admitted to be served. To this respect, we propose optimal schemes to jointly determine SLA-based prices and perform capacity planning. In spite of the usability of such a pricing model, simulations also show that it could improve the utilization of computing resource by up to eleven-fold increase, compared with the standard pay-as-you-go pricing model; furthermore, the revenue of a cloud provider could be improved by up to a five-fold increase.
Early Identification of Future Committers in Open Source Software Projects

There exists two types of developers in Open Source Software (OSS) projects: 1) Committers who have permission to commit edited source code to the Version Control System (VCS), 2) Developers who contribute source code but cannot commit to the VCS directly. In order to develop and evolve high quality OSS, projects are always in search of new committers. OSS projects often promote strong developers to become committers. When existing committers find strong developers, they propose their promotion to a committer role. Delaying the committer-promotion might lead to strong developers departing from an OSS project and the project losing them. However early committer-promotion comes with its own slew of risks as well (e.g., the promotion of inexperienced developers). Hence, committer-promotion decisions are critical for the quality and successful evolution of OSS projects. In this paper, we examine the committer-promotion phenomena for two OSS projects (Eclipse and Firefox). We find that the amount of activities by future committers was higher than the amount of activities by developers who did not become committers). We also find that some developers are promoted to a committer role very rapidly (within a few month) while some of developers take over one year to become a committer. Finally, we develop a committer-identification model to assist OSS projects identifying future committers.
Tailoring a COTS group support system for software requirements inspection

The inspection of early life-cycle artifacts such as requirement documents promises great benefits. However, research demonstrates that the inspection process is complex and expensive and that tool support would be highly desirable. Existing inspection tools focus largely on the inspection of source code. We have therefore devised groupware support for inspecting requirements. Based on our experience with adopting a group support system (GSS) for requirements negotiation, we decided to tailor this commercial GSS to support inspection of requirements. The paper discusses our concept of a Groupware-supported Requirements Inspection Process (GRIP) and shows that tailoring a COTS GSS works well to automate this process.
Role of Adipokines and Hormones of Obesity in Childhood Asthma

Purpose The aim of this study was to evaluate serum levels of leptin, ghrelin, and adiponectin in obese and non-obese children with asthma and in healthy non-asthmatic children, and analyze their relationships with clinical outcomes. Methods This study enrolled 40 obese and 51 non-obese children with asthma and 20 healthy children. Body mass index and serum leptin, ghrelin, and adiponectin levels were determined in all children. Asthma symptom scores and lung function test results were recorded for subjects with asthma. Results Serum leptin levels (11.8±7.9, 5.3±6.8, and 2.1±2.4 ng/mL in the obese asthmatic, non-obese asthmatic, and control groups, respectively) and adiponectin levels (12,586.2±3,724.1; 18,089.3±6,452.3; and 20,297.5±3,680.7 ng/mL, respectively) differed significantly among the groups (P<0.001 for all). Mean ghrelin levels were 196.1±96.8 and 311.9±352.8 pg/mL in the obese and non-obese asthmatic groups, respectively, and 348.8±146.4 pg/mL in the control group (P=0.001). The asthma symptom score was significantly higher in the obese children with asthma than in the non-obese children with asthma (P<0.001). Leptin and adiponectin levels were correlated with the asthma symptom score in non-obese children with asthma (r=0.34 and r=-0.62, respectively). Conclusions Obesity leads to more severe asthma symptoms in children. Moreover, leptin, adiponectin, and ghrelin may play important roles in the inflammatory pathogenesis of asthma and obesity co-morbidity.
Evolution of Computed Tomography Angiography Spot Sign Is Consistent With a Site of Active Hemorrhage in Acute Intracerebral Hemorrhage

Background and Purpose— CT angiography spot sign predicts hematoma expansion in patients with acute intracerebral hemorrhage (ICH). The spot sign may represent a site of active extravasation, a locus of arrested hemorrhage forming fibrin globes, or represent associated epiphenomena such as hypertensive microaneurysms. We sought to describe the evolution of spot signs over 60 seconds in acute ICH using dynamic CT angiography and determine whether they grow and diffuse into the hematoma as would be expected with active extravasation. Methods— We prospectively identified consecutive patients presenting with spontaneous ICH <6 hours from symptom onset that completed dynamic CT angiography imaging over a 60-second acquisition protocol. We determined spot positivity, quantified spot volumes, and then used repeated-measures ANOVA to assess changes in spot volume over time. Results— We collected data on 35 patients; 13 of 35 (37%) patients were spot-positive. Spot-positive patients had larger median ICH volume compared with spot-negative patients (median 10.7 versus 49.2 mL; P=0.007). Maximal spot sign volumes ranged from 0.02 to 2.8 mL (median 0.17 mL). Spot sign volumes increased significantly with time (P<0.001) and seemed to disperse into the hematoma in all cases. Three of 13 (23%) spot-positive patients presented with 2 distinct spot signs, but the remaining patients either had only 1 spot sign or different contiguous components of an irregularly shaped spot sign. Conclusions— In this dynamic CT angiography study of ICH, spot signs evolve consistent with sites of active extravasation.
Full-Length Genomic Sequence of Subgenotype IIIA Hepatitis A Virus Isolate in Republic of Korea

Hepatitis A virus is known to cause acute hepatitis and has significant implications for public health throughout the world. In the Republic of Korea, the number of patients with hepatitis A virus infection has been increasing rapidly since 2006. In this study, the Kor-HAV-F strain was identified as subgenotype IIIA by RT-PCR, and its identity was confirmed by nucleotide sequencing and alignment analysis. Moreover, detailed phylogenetic analysis indicated that the Kor-HAV-F strain clustered into subgenotype IIIA, including strains isolated in Japan, Norway, and India. The entire amino acid sequence of the VP1 and 2A regions was compared with that of the reference strains isolated in various countries. We found 2 amino acid changes (T168A and L96P, resp.) in the VP1 and 2A regions, which had not been found in any other hepatitis A virus strain. To our knowledge, this study is the first to report the full-length sequence of a hepatitis A virus isolated in the Republic of Korea.

Antisocial attitude and aggressive behavior among immigrant children: The moderating effects of parent-child relationships

ABSTRACT Guided by the ecological framework, this study explored 1) the effect of antisocial attitude as a risk factor on aggressive behavior and 2) how a maternal- or paternal-child relationship buffers the impact of antisocial attitude in predicting aggressive behavior among children attending elementary school. A convenience sampling strategy was utilized to recruit 136 immigrant children (female 54.8%, Hispanic and Latino 80.9%) attending schools in one school district in the Southwestern United States. The results showed that the effect of antisocial attitude on aggressive behavior varied depending on the children’s relationships with their parents. A close relationship with their mother mitigated the effect of antisocial attitude on aggressive behavior. Also, if the child had a positive relationship with both parents, the impact of antisocial attitude on aggressive behavior decreased. Thus, immigrant children who had a close relationship with both parents were less likely to have aggressive behavior. These results indicate that there is a benefit when children have close relationships with their parents in reducing problem behaviors.
