description: This paper is the second in a series describing the Sydney University Molonglo Sky Survey (SUMSS) being carried out at 843MHz with the Molonglo Observatory Synthesis Telescope (MOST). The survey will consist of ~590 4.3deg. x 4.3deg. mosaic images with 45"x45"cosec|dec.| resolution, and a source catalogue. In this paper we describe the initial release (version 1.0) of the source catalogue consisting of 107,765 radio sources made by fitting elliptical gaussians in 271 SUMSS mosaics to a limiting peak brightness of 6mJy/beam at dec.<=-50deg. and 10mJy/beam at dec.>-50deg.. The catalogue covers approximately 3500deg^2 of the southern sky with dec.<=-30deg., about 43 per cent of the total survey area. Positions in the catalogue are accurate to within 1"-2" for sources with peak brightness A>=20mJy/beam and are always better than 10". The internal flux density scale is accurate to within 3 per cent. Image artefacts have been classified using a decision tree, which correctly identifies and rejects spurious sources in over 96 per cent of cases. Analysis of the catalogue shows that it is highly uniform and is complete to 8mJy at dec.<=-50^deg. and 18mJy at dec.>-50deg.. In this release of the catalogue about 7000 sources are found in the overlap region with the NRAO VLA Sky Survey (NVSS) at 1.4GHz. We calculate a median spectral index of alpha=-0.83 between 1.4GHz and 843MHz. This version of the catalogue will be released via the World Wide Web with future updates as new mosaics are released.

description: The conductivity of a granular metal or an array of quantum dots usually has the temperature dependence associated with variable range hopping within the soft Coulomb gap of density of states. This is difficult to explain because neutral dots have a hard charging gap at the Fermi level. We show that uncontrolled or intentional doping of the insulator around dots by donors leads to random charging of dots and finite bare density of states at the Fermi level. Then Coulomb interactions between electrons of distant dots results in the a soft Coulomb gap. We show that in a sparse array of dots the bare density of states oscillates as a function of concentration of donors and causes periodic changes in the temperature dependence of conductivity. In a dense array of dots the bare density of states is totally smeared if there are several donors per dot in the insulator.

description: Despite ongoing research on the topic of adversarial examples in deep learning for computer vision, some fundamentals of the nature of these attacks remain unclear. As the manifold hypothesis posits, high-dimensional data tends to be part of a low-dimensional manifold. To verify the thesis with adversarial patches, this paper provides an analysis of a set of adversarial patches and investigates the reconstruction abilities of three different dimensionality reduction methods. Quantitatively, the performance of reconstructed patches in an attack setting is measured and the impact of sampled patches from the latent space during adversarial training is investigated. The evaluation is performed on two publicly available datasets for person detection. The results indicate that more sophisticated dimensionality reduction methods offer no advantages over a simple principal component analysis.

description: Primary open-angle glaucoma (POAG) is a chronic condition characterised by optic neuropathy and vision loss. Elevated intraocular pressure (IOP) can damage the optic nerve and is a risk factor for glaucoma, thus treatment usually comprises topical hypotensives. This analysis aims to address methodological issues associated with the synthesis of glaucoma clinical trial data, given variations in study methodology and IOP measurement. Meta-regression was used to estimate how IOP varies over time for patients receiving treatment. Relative treatment effects were assessed using a random-effects mixed treatment comparison (MTC) in order to preserve randomisation and avoid selection bias. To produce clinically meaningful outputs, these analyses were combined to obtain the mean on-treatment IOP and the proportion of patients achieving different IOP targets at different time points. A further MTC estimated the probability of hyperaemia events. The analysis showed that after 3 months’ treatment, between 58 and 83% of patients will have a ≥20% reduction in IOP and 70–93% of patients will have an absolute IOP <20 mmHg. Latanoprost and bimatoprost were found to produce significantly lower on-treatment IOP compared with timolol (p This analysis suggests that latanoprost and bimatoprost produce a statistically significant reduction in IOP compared with timolol, but are associated with a higher risk of hyperaemia. Out of all the prostaglandins, latanoprost may achieve a good balance between tolerability and IOP efficacy. As with all forms of meta-analysis, the results are based on the assumption that the studies and intervention groupings are sufficiently similar to be compared.

In particular, we identify the topological charges in the algebras and find BPS bounds for the energies. The charges are given by the integral over a brane's spatial worldvolume of a certain closed form built out of the Killing spinors and background fields. The existence of such closed forms for arbitrary supersymmetric backgrounds generalises the existence of calibration forms for special holonomy manifolds.

title: Using the Pomodoro Technique® to help undergraduate students better manage technology-based multitasking during independent study
title: A design-based research investigation

description: The issue of student multitasking is debated often in higher education, for example when discussing whether ‘digital native’ students can naturally multitask when using technology. Yet some students do continue to struggle with multitasking, especially when undertaking self-directed study using digital devices, and there have been few empirical investigations into how to support those students. In this thesis, I seek to investigate the effectiveness of a popular time management technique, the Pomodoro Technique® (PT), in helping students better manage technology-based multitasking during independent study. To this end, I describe a design-based research investigation comprising four cycles/iterations, dedicated in turn to understanding the reasons students multitask (cycle 1), exploring and refining the use of the technique (cycles 2-3) and following the use of the refined technique by students over two months (cycle 4). Participants were twelve undergraduate students at a UK university who self-identified as struggling with multitasking. Data collection included participant diary records and periodic interviews. Findings reveal that participants’ reasons for multitasking were varied. Most participants found the PT® helpful for addressing their multitasking. However, there was little consensus on how the PT® helped participants or which aspects were helpful, with the same aspects (e.g. ticking timer, deferring potential interruptions) identified as helpful or ineffective by different participants. The effectiveness of the technique was also impacted by contextual factors such as assessment deadlines and unconducive study environments. Overall, it seems important that students allow enough time to get used to the technique, and that they reflect on and modify how they use the technique to suit their context under appropriate guidance. The thesis contributes to the literature on student multitasking in higher education. It presents one of the first evidenced-based investigations of managing multitasking (and one of the first formal evaluation of the PT® in an academic context). The findings highlight previously overlooked reasons for student multitasking, such as the convergent use of online platforms for both study and non-study-related activities, and emphasise that technology and non-technology-based reasons for multitasking can be closely related. The thesis also argues that scholars working on student multitasking should be aware of issues highlighted in other areas of literature, such as in studies of self-efficacy and human visual processing.
Meta-analysis of the evidence for a partially hydrolyzed 100% whey formula for the prevention of allergic diseases

description: Infants with a documented hereditary risk of atopy (i.e., an affected parent and/or sibling) who cannot be breastfed exclusively are recommended to receive a formula with confirmed reduced allergenicity, i.e., a partially or extensively hydrolyzed formula (pHF and eHF, respectively), as a means of preventing allergic reactions. The efficacy of each hydrolyzed formula for the prevention of allergic diseases should be established separately, as factors such as the protein source, hydrolysis method and degree of hydrolysis that often depend on the manufacturer contribute to differences among hydrolysates. The aim was to systematically review data on the efficacy of a partially hydrolyzed 100% whey formula (pHF) in reducing the risk of allergy in healthy infants at high risk for allergy. The Cochrane Library, MEDLINE, EMBASE, and CINAHL databases were searched in September 2009 (from inception to September 2009) for randomized and quasi-randomized controlled trials (RCTs); additional references were obtained from reviewed articles. The company that manufactures the pHF used was contacted for unpublished data. The search yielded 84 citations. Fifteen RCTs were included, some of which had potential methodological limitations such as unclear or inadequate allocation concealment, no intention-to-treat analysis, and no true blinding. For primary outcomes, i.e., all allergic diseases and atopic eczema/atopic dermatitis, use of the pHF compared with standard formula (SF) was associated with reduced risks (incidence, cumulative incidence, period prevalence) that were statistically significant for most, albeit not all, time points. Comparison of groups who received the pHF versus extensively hydrolyzed (eH) whey formula revealed no significant differences in outcomes except for reductions in the cumulative incidences of all allergic diseases at 0 to 36 months of age. Comparison of groups who received the pHF versus eH casein formula revealed no significant difference in outcomes between groups. The use of the pHF compared to SF is effective in allergy prevention in children at high risk for allergy at most time points. These results should be interpreted with caution due to a lack of methodological rigor in many trials. Reassuringly, the strongest evidence comes from a well-designed and conducted, independently funded RCT.

description: We present further evidence that the magnetic chemically peculiar stars (CP2) of the upper main sequence already occur at very early stages of the stellar evolution, significantly before they reach 30% of their life-time on the main sequence. This result is especially important for models dealing with dynamo theories, angular momentum loss during the pre- as well as main sequence and evolutionary calculations for CP2 stars. Results from the literature either derived for objects in the Hyades and the UMa cluster or from the Hipparcos mission contradict each other. A way out of this dilemma is to investigate young open clusters with known ages and accurate distances (error < 10%), including CP2 members. Up to now, four open clusters fulfill these requirements: IC 2391, IC 2602, NGC 2451A and NGC 2516. In total, 13 CP2 stars can be found within these clusters. We have used the measurements and calibrations of the Geneva 7-color photometric system to derive effective temperatures and luminosities. Taking into account the overall metallicity of the individual clusters, isochrones and evolutionary tracks were used to estimate ages and masses for the individual objects. The derived ages (between 10 and 140 Myr) are well in line with those of the corresponding clusters and further strengthen the membership of the investigated CP2 stars.

description: The spontaneously formed striped polarization nanodomain configuration of a PbTiO${_3}$/SrTiO${_3}$ superlattice transforms to a uniform polarization state under above-bandgap illumination with a time dependence varying with the intensity of optical illumination and a well-defined threshold intensity. Recovery after the end of illumination occurs over a temperature-dependent period of tens of seconds at room temperature and shorter times at elevated temperatures. A model in which the screening of the depolarization field depends on the population of trapped electrons correctly predicts the observed temperature and optical intensity dependence.

Durch die qualitative Inhaltsanalyse nach Mayring wurden Schlüsselkonzepte in englischer und deutscher Literatur erfasst. Die Arbeit fokussiert auf den Zusammenhang zwischen Impulskontrolle und Verhaltensstörungen wie ADHS, ODD, SVV und ASPD. Ergebnisse zeigen, dass eine eingeschränkte Impulskontrolle auffälliges Verhalten verstärken kann, während gezielte Förderung dieses Verhalten reduziert. Dies wird auch anhand von Erkenntnissen zu neuronalen Korrelaten der Impulskontrolle diskutiert. Die Arbeit betont die Bedeutung von theoretischem (Grundlagen-)Wissen über Impulskontrolle im Spezifischen und exekutiven Funktionen im Allgemeinen für die Unterstützung von Schülerinnen und Schülern mit Verhaltensherausforderungen, um effektive Interventionsansätze für deren Förderung zu entwickeln.

description: Epidemiological data suggests for every 1% reduction in LDL-C there is a corresponding 1–1.5% reduction in cardiovascular events (CVEs). Additionally, for every 2–3% increase in HDL-C there is a reduction in CVEs by 2–4% that is independent of LDL-C. With numerous treatment options for managing dyslipidemia, it is important to evaluate agents that result in the greatest reduction of CVEs. To compare current high-potency dyslipidemia pharmacotherapy with respect to changes in LDL-C and HDL-C and estimate risk reductions for CVEs. This study is an analysis of existing published studies for dyslipidemia products marketed in the US. Literature searches were conducted using Medline, International Pharmaceutical Abstracts, Embase, and CINAH to identify trials for niacin extended-release and lovastatin (NER/L); niacin extended-release and simvastatin (NER/S); rosuvastatin (R); and, ezetimibe/simvastatin (E/S) from database inception to 1 May 2009. Demographics and changes from baseline in LDL-C and HDL-C were abstracted and HDL-C to LDL-C change (%Δ-lipids) was created for each therapy. Using a previously validated model the percent reduction in CVEs was estimated for each treatment strategy. Data for 177 treatment arms (120 unique reports), accounting for drug and dose were abstracted. The range in mean ± SD %Δ-lipids depending on drug dose was: E/S, 58 ± 6 to 67 ± 3; R, 51 ± 5 to 65 ± 5; NER/L, 33 ± 7 to 75 ± 7; and NER/S, 48 to 77 ± 4. Risk reductions were greatest for NER/statin combinations, with percent risk reductions greater than 77% for NER/S, 2000 mg/10 mg and 83% NER/S, 2000 mg/40 mg. Ignoring medication strengths, reductions in CVEs ranged from 58% for R, 60% for E/S, 61% for NER/L, and 72% for NER/S. There are several potential limitations associated with this study including: publication bias, English only search, limited published studies with NER in combination with L or S, adherent populations, and aggregation of multiple populations. The results of the analysis suggest that greater risk reductions in CVEs occur with combination therapies, especially those including niacin extended-release (NER). Up to an 83% risk reduction was estimated for the highest doses of NER and simvastatin (NER/S).

description: We explore the string spectrum in the Witten QCD model by considering classical string configurations, thereby obtaining energy formulas for quantum states with large excitation quantum numbers representing glueballs and Kaluza-Klein states. In units of the string tension, the energies of all states increase as the 't Hooft coupling $λ$ is decreased, except the energies of glueballs corresponding to strings lying on the horizon, which remain constant. We argue that some string solutions can be extrapolated to the small $λ$ regime. We also find the classical mechanics description of supergravity glueballs in terms of point-like string configurations oscillating in the radial direction, and reproduce the glueball energy formula previously obtained by solving the equation for the dilaton fluctuation.

description: The study’s objectives were (a) to characterize physicians’ attitudes and practices in relation to treating male pattern hair loss (MPHL), (b) to examine differences vis-à-vis physician distinctions, and (c) to consider the findings in relation to published research on MPHL patients’ treatment-seeking experiences. The online survey across six countries (United States, France, Germany, Spain, Japan, and Korea) involved 466 physicians (263 dermatologists and 203 primary care physicians [PCPs]) who at least occasionally treat patients for MPHL. Over 50% of physicians were cognizant of patients’ concerns and the impact of hair loss on patients’ quality of life. Moreover, 65% were comfortable talking about MPHL with patients, and 62% were comfortable recommending treatment. On the other hand, about one-third of surveyed physicians were not especially comfortable assessing and treating MPHL. Relative to PCPs, dermatologists reported a significantly greater likelihood of spending time answering questions about MPHL and treatments (89 vs. 74%, p p p In contrast to physicians less experienced with MPHL treatment, dermatologists and other physicians frequently treating MPHL have attitudes and practices that may foster a favorable context for MPHL patient care.

description: Choreographic programming (CP) is a paradigm for implementing distributed systems that uses a single global program to define the actions and interactions of all participants. Library-level CP implementations, like HasChor, integrate well with mainstream programming languages but have several limitations: Their conditionals require extra communication; they require specific host-language features (e.g., monads); and they lack support for programming patterns that are essential for implementing realistic distributed applications.
 We make three contributions to library-level CP to specifically address these challenges. First, we propose and formalize conclaves and multiply-located values, which enable efficient conditionals in library-level CP without redundant communication. Second, we propose end-point projection as dependency injection, a design pattern that enables library-level CP in host languages without support for monads. Third, we propose census polymorphism, a technique for abstracting over the number of participants in a choreography. We demonstrate these contributions via implementations in Haskell, Rust, and TypeScript.

description: We present PFNN, a penalty-free neural network method, to efficiently solve a class of second-order boundary-value problems on complex geometries. To reduce the smoothness requirement, the original problem is reformulated to a weak form so that the evaluations of high-order derivatives are avoided. Two neural networks, rather than just one, are employed to construct the approximate solution, with one network satisfying the essential boundary conditions and the other handling the rest part of the domain. In this way, an unconstrained optimization problem, instead of a constrained one, is solved without adding any penalty terms. The entanglement of the two networks is eliminated with the help of a length factor function that is scale invariant and can adapt with complex geometries. We prove the convergence of the PFNN method and conduct numerical experiments on a series of linear and nonlinear second-order boundary-value problems to demonstrate that PFNN is superior to several existing approaches in terms of accuracy, flexibility and robustness.

description: Biredox ionic liquids are a new class of functionalized electrolytes that may play an important role in future capacitive energy storage devices. By allowing additional storage of electrons inside the liquids, they can improve device performance significantly. However current devices employ nanoporous carbons in which the diffusion of the liquid and the adsorption of the ions could be affected by the occurrence of electron-transfer reactions. It is therefore necessary to understand better the thermodynamics and the kinetics of such reactions in biredox ionic liquids. Here we perform ab initio molecular dynamics simulations of both the oxidized and reduced species of several redox-active ionic molecules (used in biredox ionic liquids) dissolved in acetonitrile solvent and compare them with the bare redox molecules. We show that in all the cases, it is necessary to introduce a two Gaussian state model to calculate the reaction free energies accurately. These reaction free energies are only slightly affected by the presence of the IL group on the molecule. We characterize the structure of the solvation shell around the redox active part of the molecules and show that in the case of TEMPO-based molecules strong reorientation effects occur during the oxidation reaction.

description: We consider the Hamiltonian BRST quantization of a noncommutative non abelian gauge theory. The Seiberg-Witten map of all phase-space variables, including multipliers, ghosts and their momenta, is given in first order in the noncommutative parameter $θ$. We show that there exists a complete consistence between the gauge structures of the original and of the mapped theories, derived in a canonical way, once we appropriately choose the map solutions.

description: Surveys evaluating plasma lipid goal attainment in patients with coronary heart disease have shown that hypercholesterolaemia is inadequately treated. Limited data account for the reasons behind this. The aim of the CEntralized Pan-European survey on tHE Under-treatment of hypercholeSterolaemia (CEPHEUS) survey was to evaluate the current use and efficacy of lipid-lowering drugs (LLD), and to identify possible patient/physician characteristics associated with failure to achieve low-density lipoprotein cholesterol (LDL-C) targets recommended by the 2003 European guidelines (Third Joint Task Force). CEPHEUS was a European, multi-centre, cross-sectional survey conducted in eight countries and involved patients on LLD for >3 months (stable medication >6 weeks). One visit was scheduled for data collection, including fasting lipids. In all but one country, physicians and patients filled in a questionnaire about aspects of hypercholesterolaemia and treatment. Trial registration:ClinicalTrials.gov identifier: NCT00542867. Of the 15 199 patients recruited, 14 478 were included in the final analyses. The mean age was 63.2 years, and 45% of patients were female. Overall, 55.3% of the patients achieved their LDL-C target. In multivariate analyses, the factors identified as positive predictors for achieving LDL-C goals included normal body mass index, not smoking, not having metabolic syndrome, being on statin therapy and good treatment adherence. The population was a selected group of subjects treated with LLD, and the results cannot be extrapolated to the general population. Patient consent was obtained, which may have selected more motivated patients and induced a positive bias. The physician and patient questionnaires were not validated, but were only used for exploratory purposes. Only 55.3% of patients using LLD achieved the LDL-C target recommended in the 2003 European guidelines.

description: We have found an unusual competition of two frustration mechanisms in the 2D quantum antiferromagnet Cs$_2$CoBr$_4$. The key actors are the alternation of single-ion planar anisotropy direction of the individual magnetic Co$^{2+}$ ions, and their arrangement in a distorted triangular lattice structure. In particular, the uniquely oriented Ising-type anisotropy emerges from the competition of easy-plane ones, and for a magnetic field applied along this axis one finds a cascade of five ordered phases at low temperatures. Two of these phases feature magnetization plateaux. The low-field one is supposed to be a consequence of a collinear ground state stabilized by the anisotropy, while the other plateau bears characteristics of an "up-up-down" state exclusive for lattices with triangular exchange patterns. Such coexistence of the magnetization plateaux is a fingerprint of competition between the anisotropy and the geometric frustration in Cs$_2$CoBr$_4$.

title: Compression-Responsive Photonic Crystals Based on Fluorine-Containing Polymers
Creators: name: Kredel, Julia

Publisher: name: MDPI

description: Fluoropolymers represent a unique class of functional polymers due to their various interesting and important properties such as thermal stability, resistance toward chemicals, repellent behaviors, and their low refractive indices in comparison to other polymeric materials. Based on the latter optical property, fluoropolymers are particularly of interest for the preparation of photonic crystals for optical sensing application. Within the present study, photonic crystals were prepared based on core-interlayer-shell particles focusing on fluoropolymers. For particle assembly, the melt-shear organization technique was applied. The high order and refractive index contrast of the individual components of the colloidal crystal structure lead to remarkable reflection colors according to Bragg’s law of diffraction. Due to the special architecture of the particles, consisting of a soft core, a comparably hard interlayer, and again a soft shell, the resulting opal films were capable of changing their shape and domain sizes upon applied pressure, which was accompanied with a (reversible) change of the observed reflection colors as well. By the incorporation of adjustable amounts of UV cross-linking agents into the opal film and subsequent treatment with different UV irradiation times, stable and pressure-sensitive opal films were obtained. It is shown that the present strategy led to (i) pressure-sensitive opal films featuring reversibly switchable reflection colors and (ii) that opal films can be prepared, for which the written pattern—resulting from the compressed particles—could be fixed upon subsequent irradiation with UV light. The herein described novel fluoropolymer-containing photonic crystals, with their pressure-tunable reflection color, are promising candidates in the field of sensing devices and as potential candidates for anti-counterfeiting materials.

description: The aim of this paper is to compare some parameter estimation methods for the three-parameter kappa distribution, which is used in analysing precipitation, wind speed and streamflow data in hydrology. These methods include: method of L-moments (LM), maximum likelihood (ML), maximum product of spacings (MPS), location and scale parameters free maximum likelihood (LSPF), location parameter free maximum likelihood (LPF) and shrinkage estimation (SH). To compare the performance of these methods, some Monte Carlo simulation studies are applied. To demonstrate the usefulness of the three-parameter kappa distribution and its applications to hydrology, statistical analyses of two precipitation datasets are presented.

description: of a building during its construction and operation stages. However, current methods cannot match and segment instances with a high-resolution result in real, complex environments regarding mechanical, electrical, and plumbing (MEP) objects, since the geometry of as-built MEP objects is complex and often deviates from as-designed models in terms of position, orientation, and scale. To this end, this paper proposes a hybrid method by fusing point clouds, images, and 3D models to efficiently segment complex MEP components in buildings. An experiment targeting heating terminals in a real 3-floor staircase space shows the feasibility and practicality of the proposed method.
