The IDV source J 1128+5925, a new candidate for annual modulation?

Context. Short time-scale radio variations of compact extragalactic radio sources, known as IntraDay Variability (IDV), can be explained in at least some sources by a source-extrinsic effect, in which the variations are interpreted as scintillation of radio waves caused by the turbulent interstellar medium of the Milky Way. One of the most convincing observational arguments in favour of propagation-induced variability is the so-called “annual modulation” of the characteristic variability time-scale, which is due to the orbital motion of the Earth. So far there are only two sources known which show such a well-defined seasonal cycle, a few more sources with fewer data can be regarded as possible candidates for this effect. However, source-intrinsic effects, such as structural variations, can also cause the observed changes of the variability time-scale. Data for the new, recently discovered, and highly variable IDV source J 1128+5925 are presented. Aims. We study the frequency and time dependence of the IDV in this compact quasar. We measure the characteristic variability time-scale of the IDV throughout the year, and analyze whether the observed changes in the variability time-scale are consistent with annual modulation. Assuming a radio wave propagation effect as origin, we are able to constrain some physical properties (such as distance, scattering-strength, and possible anisotropy) of the “plasma” screen, which may cause the scintillation. Methods. We monitored the flux density variability of J 1128+5925 with dense time sampling between 2.7 and 10.45 GHz. We observed with the 100 m Effelsberg radio telescope of the Max-Planck-Institut fur Radioastronomie (MPIfR) at 2.70 GHz, 4.85 GHz, and 10.45 GHz, as well as with the 25 m Urumqi radio telescope (China) at 4.85 GHz. From ten observing sessions, each of which lasted several days during the period between 2004–2006, we determine the variability characteristics and time-scales which we investigate in view of possible scintillation and annual modulation. Results. The observed pronounced changes of the variability time-scale of J 1128+5925 are modelled with an anisotropic annual modulation model. The observed frequency dependence of the variation is in good agreement with the prediction from interstellar scintillation. Adopting a simple model for the annual modulation model and also using the frequency dependence of the IDV, we derive a lower limit to the distance the scattering screen and an upper limit for the scintillating source size. The latter is found to be consistent with the measured core size from Very Long Baseline Interferometry (VLBI).
Risk and morality

Risk and Morality examines how decisions about risk and uncertainty relate to moral principles and ethical conduct. Editors Richard Ericson and Aaron Doyle have brought together in this volume a selection of original essays on the topic by renowned scholars in the disciplines of philosophy, sociology, law, political science, geography, criminology, and accounting from Canada, the United States, England, France, and Australia. Presenting cutting-edge theory and research, the essays analyse the broader social, political, economic and cultural dimensions of risk and morality. The concept of risk has become pervasive in recent years in political discourse, popular culture, organizational communications, and everyday life. The contributors' respective research projects on risk and morality in politics, business, legal regulation, crime prevention, insurance, extreme sports, and biotechnology provide original empirical evidence to substantiate their theories and address the ideological and policy relevance of their work. Collectively, the contributors explain why risk is such a key aspect of Western culture, and demonstrate that new regimes for risk management are transforming social integration, value-based reasoning and morality. Further, they illustrate that these new regimes do not necessarily foster more responsible conduct or greater accountability in institutions.
Efficient and Fair Throughput-Optimal Scheduling in Buffer-Aided Relay-Based Cellular Networks

In this letter, we study throughput-optimal scheduling policies in single-path buffer-aided relay networks, where the packets of a user travel one fixed path from the source to the destination and do not require routing. We modify the well-known Max-Weight (MW) policy and propose a version of throughput-optimal algorithms, which we refer to as Modified MW (MMW). In MMW, by defining a suitably large threshold, a link's weight is proportional to just the corresponding local queue size either in the base station or the relay station, in most of the time slots. Moreover, a parameter can be adjusted for improving delay fairness between the relayed and direct users. MMW is suitable for use in both shared and independent channel scenarios and facilitates decentralized network implementations. Numerical results confirm that MMW is better able to provide similar performance for direct and relayed users in terms of queueing delay, compared with the existing algorithms.
Predicting the Compositionality of Multiword Expressions Using Translations in Multiple Languages

In this paper, we propose a simple, languageindependent and highly effective method for predicting the degree of compositionality of multiword expressions (MWEs). We compare the translations of an MWE with the translations of its components, using a range of different languages and string similarity measures. We demonstrate the effectiveness of the method on two types of English MWEs: noun compounds and verb particle constructions. The results show that our approach is competitive with or superior to state-of-the-art methods over standard datasets.
Cohort profile: the Dutch 'TRacking Adolescents' Individual Lives' Survey'; TRAILS.

Mental disorders account for one-fifth of the total burden of disease in the Western world, 1 and, as such, should require due attention from the international epidemiological research community. Good quality research on the aetiology and course of psychopathology in the population is impossible without reliable and valid data from long-term longitudinal cohort studies. Research on psychopathology in adolescence is important both from a scientific point of view and from the point of view of prevention and public health policy. Adolescence is characterized by major biological, psychological and social challenges and opportunities, where interaction between the individual and environment is intense, and developmental pathways are set in motion or become established. 2–4 Furthermore, adolescent psychopathology can have important consequences for education, relationships and socioeconomic achievement in later life. 5–7 These characteristics of adolescence do not only set high demands for cohort studies aiming to capture the most salient aspects of developmental pathways, they also ensure a great gain in empirical knowledge and an invaluable source of information for public health policy from such studies. In order to fully benefit from this potential, a multidisciplinary approach is essential.
Portrayal of Characters with Disabilities in Newbery Books

PORTRAYAL OF CHARACTERS WITH DISABILITIES IN NEWBERY BOOKS Melissa Leininger Department of Counseling Psychology and Special Education Educational Specialist in School Psychology Newbery books represent quality literature that is likely to be used for bibliotherapy, yet these books have not been systematically evaluated for their portrayal of characters with disabilities. Thirty Newbery Award and Honor books from 1975–2008 were identified that contained 40 characters with disabilities. These books were evaluated using a rating scale that combines literary standards and standards relating to individuals with disabilities. The types of disabilities and personal characteristics such as gender, age, and race were documented and the personal portrayal of characters with disabilities and exemplary practices in these books were evaluated. This information was compared to the current school special education population. The most commonly found disabilities were orthopedic impairment, emotional disturbance, and mental retardation. The majority of characters were portrayed realistically and positively and the personal portrayal and depiction of exemplary practices and social interactions with others has improved over time. When comparing school age characters to students receiving special education services today, though, some discrepancies arise. While the most commonly portrayed disabilities for school-age characters in Newbery books were mental retardation, orthopedic impairment, autism, and multiple disabilities, the most common disabilities of students receiving special education services are specific learning disability, speech or language impairment, mental retardation, and other health impairment. Also, White school-age characters with disabilities were overrepresented while Black characters and Hispanic characters were underrepresented and other ethnicities were not represented at all. This study is relevant to parents, teachers, librarians, and school psychologists who are interested in selecting appropriate books to encourage understanding and acceptance of students with disabilities.

Live dense reconstruction with a single moving camera

We present a method which enables rapid and dense reconstruction of scenes browsed by a single live camera. We take point-based real-time structure from motion (SFM) as our starting point, generating accurate 3D camera pose estimates and a sparse point cloud. Our main novel contribution is to use an approximate but smooth base mesh generated from the SFM to predict the view at a bundle of poses around automatically selected reference frames spanning the scene, and then warp the base mesh into highly accurate depth maps based on view-predictive optical flow and a constrained scene flow update. The quality of the resulting depth maps means that a convincing global scene model can be obtained simply by placing them side by side and removing overlapping regions. We show that a cluttered indoor environment can be reconstructed from a live hand-held camera in a few seconds, with all processing performed by current desktop hardware. Real-time monocular dense reconstruction opens up many application areas, and we demonstrate both real-time novel view synthesis and advanced augmented reality where augmentations interact physically with the 3D scene and are correctly clipped by occlusions.
Anisotropic Norm Bounded Real Lemma for Linear Discrete Time Varying Systems

We consider a finite horizon linear discrete time varying system whose input is a random noise with an imprecisely known probability law. The statistical uncertainty is described by a nonnegative parameter a which constrains the anisotropy of the noise as an entropy theoretic measure of deviation of the actual noise distribution from Gaussian white noise laws with scalar covariance matrices. The worst-case disturbance attenuation capabilities of the system with respect to the statistically uncertain random inputs are quantified by the a-anisotropic norm which is an appropriately constrained operator norm of the system. We establish an anisotropic norm bounded real lemma which provides a state-space criterion for the a-anisotropic norm of the system not to exceed a given threshold. The criterion is organized as an inequality on the determinants of matrices associated with a difference Riccati equation and extends the Bounded Real Lemma of the H-infinity-control theory. We also provide a necessary background on the anisotropy-based robust performance analysis.
Comparative Studies of Mutations in Animal Isolates and Experimental In Vitro- and In Vivo-Selected Mutants ofSalmonella spp. Suggest a Counterselection of Highly Fluoroquinolone-Resistant Strains in the Field

ABSTRACT The occurrence of mutations in the genes coding for gyrase (gyrA and gyrB) and topoisomerase IV (parE and parC) of Salmonella typhimurium experimental mutants selected in vitro and in vivo and of 138 nalidixic acid-resistant Salmonella field isolates was investigated. The sequencing of the quinolone resistance-determining region of these genes in highly fluoroquinolone-resistant mutants (MICs of 4 to 16 μg/ml) revealed the presence of gyrA mutations at codons corresponding to Gly-81 or Ser-83, some of which were associated with a mutation at Asp-87. No mutations were found in the gyrB,parC, and parE genes. An assay combining allele-specific PCR and restriction fragment length polymorphism was developed to rapidly screen mutations at codons 81, 83, and 87 ofgyrA. The MICs of ciprofloxacin for the field isolates reached only 2 μg/ml, versus 16 μg/ml for some in vitro-selected mutants. The field isolates, like the mutants selected in vivo, had only a single gyrA mutation at codon 83 or 87. SinglegyrA mutations were also found in highly resistant in vitro-selected mutants (MIC of ciprofloxacin, 8 μg/ml), which indicates that mechanisms other than the unique modification of the intracellular targets could participate in fluoroquinolone resistance in Salmonella spp. A comparison of experimental mutants selected in vitro, field strains, and mutants selected in vivo suggests that highly fluoroquinolone-resistant strains are counterselected in field conditions in the absence of selective pressure.
Incidence of Childhood Leukemia and Oil Exploitation in the Amazon Basin of Ecuador

Abstract To determine whether there was any difference in childhood leukemia incidence rates between populations living in the proximity to oil fields and those living in areas free from oil exploitation in the Amazon basin of Ecuador, 91 cancer cases among children (0–14 years) from the provinces of Sucumbios, Orellana, Napo, and Pastaza during the period 1985–2000 were studied. The relative risks for all leukemias indicated significantly elevated levels in the youngest age group (0–4 years), both genders combined (RR 3.48, 95% CI 1.25–9.67), and in all age groups (0–14 years) combined for females (RR 2.60, 95% CI 1.11–6.08) and both genders combined (RR 2.56,95% CI 1.35–4.86). There was no significant difference between the two groups in all other cancer sites combined. Study results are compatible with a relationship between childhood leukemia incidence and living in the proximity of oil fields in the Ecuadorian Amazon.
Virtual boundary method for the analysis of elliptically cross-sectional photonic-crystal fibers with elliptical pores

This paper introduces a new semianalytical method for the analysis of propagation characteristics of elliptically cross-sectional photonic-crystal fibers (PCFs) with elliptical pores. This method known as a virtual boundary method (VBM) is based on the equivalency between an actual PCF and a three-layered, transversely inhomogeneous waveguide. The complicated refractive-index profile of the PCF is written as a double Fourier series, and an approximate separable wave equation is found in an elliptical coordinate system for the longitudinal field components. The exact solution to the derived equation is expressed in terms of higher order transcendental functions, such as regular and irregular Coulomb-wave functions and Mathieu functions. After having expressed all the field components, boundary conditions are imposed on the boundaries, and then, a transcendental equation for the propagation constant is derived, which is solved numerically. The validity of the method is ensured by comparing various quantities, such as effective indexes, modal birefringences, and electromagnetic field distributions, with those from an accurate full-vector finite-element method (FEM) simulator, showing relatively good agreement between the results. The method correctly confirms some of the unique PCFs' properties, such as strong localization of light within the fiber and enhancement of modal birefringence as a function of the topology of hole arrangement.
Clinical management of patients with ASXL1 mutations and Bohring–Opitz syndrome, emphasizing the need for Wilms tumor surveillance

Bohring–Opitz syndrome is a rare genetic condition characterized by distinctive facial features, variable microcephaly, hypertrichosis, nevus flammeus, severe myopia, unusual posture (flexion at the elbows with ulnar deviation, and flexion of the wrists and metacarpophalangeal joints), severe intellectual disability, and feeding issues. Nine patients with Bohring–Opitz syndrome have been identified as having a mutation in ASXL1. We report on eight previously unpublished patients with Bohring–Opitz syndrome caused by an apparent or confirmed de novo mutation in ASXL1. Of note, two patients developed bilateral Wilms tumors. Somatic mutations in ASXL1 are associated with myeloid malignancies, and these reports emphasize the need for Wilms tumor screening in patients with ASXL1 mutations. We discuss clinical management with a focus on their feeding issues, cyclic vomiting, respiratory infections, insomnia, and tumor predisposition. Many patients are noted to have distinctive personalities (interactive, happy, and curious) and rapid hair growth; features not previously reported. © 2015 Wiley Periodicals, Inc.
Maraviroc Intensification of cART in Patients with Suboptimal Immunological Recovery: A 48-Week, Placebo-Controlled Randomized Trial

Objective The immunomodulatory effects of the CCR5-antagonist maraviroc might be beneficial in patients with a suboptimal immunological response, but results of different cART (combination antiretroviral therapy) intensification studies are conflicting. Therefore, we performed a 48-week placebo-controlled trial to determine the effect of maraviroc intensification on CD4+ T-cell counts and immune activation in these patients. Design Double-blind, placebo-controlled, randomized trial. Methods Major inclusion criteria were 1. CD4+ T-cell count <350 cells/μL while at least two years on cART or CD4+ T-cell count <200 cells/μL while at least one year on cART, and 2. viral suppression for at least the previous 6 months. HIV-infected patients were randomized to add maraviroc (41 patients) or placebo (44 patients) to their cART regimen for 48 weeks. Changes in CD4+ T-cell counts (primary endpoint) and other immunological parameters were modeled using linear mixed effects models. Results No significant differences for the modelled increase in CD4+ T-cell count (placebo 15.3 CD4+ T cells/μL (95% confidence interval (CI) [1.0, 29.5] versus maraviroc arm 22.9 CD4+ T cells/μL (95% CI [7.4, 38.5] p = 0.51) or alterations in the expression of markers for T-cell activation, proliferation and microbial translocation were found between the arms. However, maraviroc intensification did increase the percentage of CCR5 expressing CD4+ and CD8+ T-cells, and the plasma levels of the CCR5 ligand MIP-1β. In contrast, the percentage of ex-vivo apoptotic CD8+ and CD4+ T-cells decreased in the maraviroc arm. Conclusions Maraviroc intensification of cART did not increase CD4+ T-cell restoration or decrease immune activation as compared to placebo. However, ex-vivo T-cell apoptosis was decreased in the maraviroc arm. Trial Registration ClinicalTrials.gov NCT00875368

Administration of antibiotics to ewes at the beginning of the dry-period

The objective of the present paper is to review the significance of administration of antibiotics at the end of a lactation period/beginning of the dry-period in ewes. During the stage of active involution, there is an increased risk of new mastitis cases and recrudescence of subclinical infections that had occurred during the previous lactation period. The main pathogens involved in the so-called ‘dry-period mastitis’ are coagulase-negative staphylococci. The principle of antibiotic administration at the end of a lactation period involves the intramammary infusion of a preparation to both mammary glands of ewes in the flock. Although a variety of products is licensed for administration in ewes, preferably the product for administration should be selected on the results of susceptibility testing of bacteria to be isolated from samples from ewes in the flock. In many clinical studies from around the world, performed in dairy- or mutton-production flocks, administration of antimicrobial agents at the end of a lactation period has been found beneficial in curing intramammary infections present at cessation of a lactation period, as well as in minimising the risk for intramammary infections during the dry-period. In dairy flocks, there are also benefits from increase in milk yield and decrease flock bulk milk mean somatic cell counts during the subsequent lactation period. Antibiotic administration at drying-off may be performed to all animals in a flock (‘complete’) or only to those considered to be infected (‘selective’). In all cases, after administration of the antibiotic, definite and complete cessation of the lactation period is essential for success of the procedure. Moreover, maintenance of the prescribed withdrawal periods is essential to safeguard public health. The procedure should always be applied as part of a strategic udder health management plan in a flock; implementation improves the welfare of animals and affords significant financial benefits to the farmer. A mastitis prevention scheme during lactation will minimise the incidence of the disease; effective treatment of cases of the disease during lactation will decrease the bacterial populations in the flock and limit risk of infection of other animals. Administration of antibiotics at the end of a lactation period will complement the above procedures and will contribute to improved mammary health for the forthcoming lactation period.
