description: In this study, we present a suite of high-resolution numerical simulations of an isolated galaxy to test a sub-grid framework to consistently follow the formation and dissociation of H$_2$ with non-equilibrium chemistry. The latter is solved via the package KROME, coupled to the mesh-less hydrodynamic code GIZMO. We include the effect of star formation (SF), modelled with a physically motivated prescription independent of H$_2$, supernova feedback and mass losses from low-mass stars, extragalactic and local stellar radiation, and dust and H$_2$ shielding, to investigate the emergence of the observed correlation between H$_2$ and SF rate surface densities. We present two different sub-grid models and compare them with on-the-fly radiative transfer (RT) calculations, to assess the main differences and limits of the different approaches. We also discuss a sub-grid clumping factor model to enhance the H$_2$ formation, consistent with our SF prescription, which is crucial, at the achieved resolution, to reproduce the correlation with H$_2$. We find that both sub-grid models perform very well relative to the RT simulation, giving comparable results, with moderate differences, but at much lower computational cost. We also find that, while the Kennicutt-Schmidt relation for the total gas is not strongly affected by the different ingredients included in the simulations, the H$_2$-based counterpart is much more sensitive, because of the crucial role played by the dissociating radiative flux and the gas shielding.

description: This paper is concerned with the Laplace boundary-value problem with the directional derivative, corresponding to the specific nature of measurements of the longitudinal component of the photospheric magnetic field. Boundary conditions are specified by a distribution on the sphere of projection of the magnetic field vector unto a given direction. It is shown that the solution of this problem exists in the form of a spherical harmonic expansion, and uniqueness of this solution is proved. A conceptual sketch of numerical determination of the harmonic series coefficients is given. The field of application of the method is analyzed having regard to the peculiarities of actual data. Finally, we present differences in results derived from extrapolating the magnetic field from a synoptic map and a full-disk magnetogram.

description: The Paris Agreement has confirmed that the ultimate climate policy goal is to hold the increase in the global average temperature to well below 2 °C above pre-industrial levels and to pursue efforts to limit the increase to 1.5 °C. Moving the goal from 2 °C to 1.5 °C calls for much more concerted effort, and presents greater challenges and costs. This study uses an Asia-Pacific Integrated Model/Computable General Equilibrium (AIM/CGE) to evaluate the role of socioeconomic factors (e.g. technological cost and energy demand assumptions) in changing mitigation costs and achieving the 1.5 °C and 2 °C goals, and to identify the channels through which socioeconomic factors affect mitigation costs. Four families of socioeconomic factors were examined, namely low-carbon energy-supply technologies, end-use energy-efficiency improvements, lifestyle changes and biomass-technology promotion (technology cost reduction and social acceptance promotion). The results show that technological improvement in low-carbon energy-supply technologies is the most important factor in reducing mitigation costs. Moreover, under the constraints of the 1.5 °C goal, the relative effectiveness of other socioeconomic factors, such as energy efficiency improvement, lifestyle changes and biomass-related technology promotion, becomes more important in decreasing mitigation cost in the 1.5 °C scenarios than in the 2 °C scenarios.

description: We show that a measurement of the reaction energy dependence of relative hadron resonance yields in heavy ion collisions can be used to study the phase structure of the dense QCD matter created in these collisions, and investigate the origin of the trends observed in the excitation functions of certain soft hadronic observables. We show that presence of chemical nonequilibrium in light quark abundance imparts a characteristic signature on the energy dependence of resonance yields, that differs considerably from what is expected in the equilibrium picture.

description: Purpose Sleep problems reported by hematological cancer patients are usually linked to higher levels of cancer-related fatigue. Although the awareness of sleep problems in solid cancer patients is rising, there has been less attention to the issue in hematological cancer patients. The present study assesses the differences in sleep by comparing physical activity and fatigue levels among hematological cancer patients during the onset of chemotherapy. Furthermore, it investigates the relationship between sleep, physical activity, and fatigue through mediation analysis. Methods The recruited sample consists of 58 newly diagnosed hematological cancer patients (47.1 ± 15.4 yrs; 51.7% males). Subjects completed questionnaires assessing sleep (PSQI), physical activity (visual analogue scale), fatigue (MFI-20), anxiety, depression (HADS), and quality of life (EORTC QLQ-C30) within two weeks from starting treatment. Results The sample reported more sleep problems in comparison to the German population norm. The classification as good (ca 25%) or bad sleepers (ca 75%) showed less frequent physical activity (p = .04), higher fatigue (p = .032), anxiety (p = .003), depression (p = .011) and pain (p = .011) in bad sleepers. The mediation analysis revealed significant indirect effects of sleep on fatigue through physical activity habits. Conclusions This study highlights the combined action of sleep problems and physical activity on fatigue during the onset of induction chemotherapy. These two parameters could represent meaningful intervention targets to improve a patient’s status during chemotherapy. Trial registration The study was registered on the WHO trial register (DRKS00007824).

description: Ferromagnetism in one dimension is a novel observation which has been reported in a recent work (P. Gambardella et.al., Nature {\bf 416}, 301 (2002)), anisotropies are responsibles in that relevant effect. In the present work, another approach is used to obtain transition between two different magnetic ordering phases. Critical temperature has been estimated by Binder method. Ferromagnetic long range interactions have been included in a special Hamiltonian through a power law that decays at large inter-particle distance $r$ as $r^{-α}$, where $α\geq0$. For the present model, we have found that the trend of the critical temperature vanishes when the range of interactions decreases ($α\to\infty$) and close to mean field approximation when the range of interactions increases ($α\to0$). The crossover between two these limit situations is discussed

Ecosystem observation, processes and dynamics

description: No abstracts are to be cited without prior reference to the author.In Belgium a 4 year project called INRAM (Integrated Risk Assessment and Monitoring of micropollutants in the Belgian coastal zone) is currently underway. The project is financed by the Belgian Federal Science Policy Office and aims to assess in an integrated approach the risks of micropollutants to Belgian coastal zone ecosystems and man. Passive sampling will be used as an innovative approach to measure contaminant pressure in the environment. During the project, a large group of hydrophobic organics will be measured at nine sampling points with passive samplers. Passive sampling will also be used as a tool for in lab toxicity tests at constant and environmentally relevant concentrations. Through the ‘reverse’ use of passive samplers toxicity assays will be performed with complex mixtures of contaminants.

description: We study the bound nucleon sigma term and the quark condensate in nuclear matter. In the quark-meson coupling (QMC) model the nuclear correction to the sigma term is small and negative, i.e., it decelerates the decrease of the quark condensate in nuclear matter. However, the quark condensate in nuclear matter is controlled primarily by the scalar-isoscalar $σ$ field. Compared to the leading term, it moderates the decrease more than that of the nuclear sigma term alone at densities around and larger than the normal nuclear matter density.

A unified model for age-velocity dispersion relations in Local Group galaxies: Disentangling ISM turbulence and latent dynamical heating

description: We analyze age-velocity dispersion relations (AVRs) from kinematics of individual stars in eight Local Group galaxies ranging in mass from Carina ($M_{*} \sim 10^{6}$) to M31 ($M_{*} \sim 10^{11}$). Observationally the $σ$ vs. stellar age trends can be interpreted as dynamical heating of the stars by GMCs, bars/spiral arms, or merging subhalos; alternatively the stars could have simply been born out of a more turbulent ISM at high redshift and retain that larger velocity dispersion till present day - consistent with recent IFU studies. To ascertain the dominant mechanism and better understand the impact of instabilities and feedback, we develop models based on observed SFHs of these Local Group galaxies in order to create an evolutionary formalism which describes the ISM velocity dispersion due to a galaxy's evolving gas fraction. These empirical models relax the common assumption that the stars are born from gas which has constant velocity dispersion at all redshifts. Using only the observed SFHs as input, the ISM velocity dispersion and a mid-plane scattering model fits the observed AVRs of low mass galaxies without fine tuning. Higher mass galaxies above $M_{vir} > 10^{11}$ need a larger contribution from latent dynamical heating processes (for example minor mergers), in excess of the ISM model. Using the SFHs we also find that supernovae feedback does not appear to be a dominant driver of the gas velocity dispersion compared to gravitational instabilities - at least for dispersions $σ\gtrsim 25$ km/s. Together our results point to stars being born with a velocity dispersion close to that of the gas at the time of their formation, with latent dynamical heating operating with a galaxy mass-dependent efficiency. These semi-empirical relations may help constrain the efficiency of feedback and its impact on the physics of disk settling in galaxy formation simulations.

description: No abstracts are to be cited without prior reference to the author.The equilibrium partitioning theory (EqP) has commonly been used to describe the bioavailability of chemicals in sediment-water systems. The EqP theory assumes that the distribution of hydrophobic organic chemicals is in equilibrium among the lipids of the organism, the organic carbon (OC) and pore water (Cw) of the sediment. The aim of present study was to test if the bioavailability of sediment associated radiolabelled hydrophobic contaminants (Chlorpyrifos, pyrene, TBDE, TCBP) can be predicted by POM-based freely dissolved pore water concentrations. It appeared that a long time (at least 8 weeks) is needed to reach equilibrium for the POM-water partitioning coefficient (Kp). However, time for Kp was satisfactory to determine the organic carbon/water distribution coefficient (Koc) and enabled to calculate freely dissolved TPCB concentrations in pore water (Cw). In the present data, the predicted bioaccumulation from pore water (BCF*Cw) agrees with the observed bioaccumulation

description: Motivation gilt als ein zentraler Antreiber von schulischen Lernprozessen und ist positiv mit Leistungen von Lernenden verknüpft. Allerdings sinkt die Motivation vieler Schülerinnen und Schüler im Verlauf der Schulzeit ab, sodass der Unterstützung motivationaler Merkmale von Lernenden eine wichtige Rolle bereits im Grundschulkontext zukommt. Die vorliegende Dissertation beschäftigte sich ausgehend von theoretischen Annahmen und empirischen Befunden zu Unterrichtsqualität und Motivationspsychologie daher mit der übergeordneten Frage, wie Gestaltungsmerkmale des Unterrichts und motivationale Merkmale von Grundschulkindern zusammenhängen. Die Dissertation umfasst vier Einzelbeiträge. In den Beiträgen I und II standen Zusammenhänge zwischen der Motivierungsqualität des Unterrichts und motivationalen Merkmalen von Lernenden in den Domänen Mathematik und naturwissenschaftlicher Sachunterricht im Fokus. Darüber hinaus wurde in Beitrag II analysiert, welche Relevanz schulische Leistungen und Kompetenzerleben der Lernenden im Unterricht für die intrinsische Motivation und das Fähigkeitsselbstkonzept in Mathematik besitzen. Für beide untersuchte Domänen ergab sich, dass eine höher wahrgenommene Motivierungsqualität des Unterrichts mit einer höheren intrinsischen Motivation und einem günstigeren Fähigkeitsselbstkonzept der Lernenden verknüpft war. Außerdem mediierte das Kompetenzerleben die Zusammenhänge zwischen Motivierungsqualität des Mathematikunterrichts bzw. Mathematiknote und dem Fähigkeitsselbstkonzept der Kinder. In den Beiträgen III und IV wurde in der Domäne Lesen analysiert, ob das Textinteresse von Grundschulkindern mit verschiedenen Textmerkmalen (z. B. Textthema) und dem Textverstehen verbunden war. Dabei wurde insbesondere auf mögliche Geschlechterunterschiede fokussiert. Die Ergebnisse verdeutlichten, dass spezifische Textmerkmale systematisch mit dem Textinteresse der Kinder verknüpft waren und ein höheres Textinteresse mit einem besseren Textverstehen einherging. Zudem wurden geschlechtsspezifische Befundmuster identifiziert: Mädchen berichteten zum Beispiel im Vergleich zu Jungen ein durchschnittlich höheres und weniger selektives Interesse. Insgesamt umfasst die Dissertation wichtige empirische Befunde zur Motivationsunterstützung im Grundschulunterricht, die im aktuellen Forschungsstand verortet werden. Mögliche Implikationen für zukünftige Bildungsforschung und Schulpraxis werden beleuchtet und diskutiert.

description: This article surveys a number of theoretical problems and open questions in the field of two-dimensional dilute Bose gases with weak repulsive interactions. In contrast to three dimensions, in two dimensions the formation of long-range order is prohibited by the Bogoliubov-Hohenberg theorem, and Bose-Einstein condensation is not expected to be realized. Nevertheless, first experimental indications supporting the formation of the condensate in low dimensional systems have been recently obtained. This unexpected behaviour appears to be due to the non-uniformity, introduced into a system by the external trapping potential. Theoretical predictions, made for homogeneous systems, require therefore careful reexamination. We survey a number of popular theoretical treatments of the dilute weakly interacting Bose gas and discuss their regions of applicability. The possibility of Bose-Einstein condensation in a two-dimensional gas, the validity of perturbative t-matrix approximation and diluteness condition are issues that we discuss in detail.

description: Citizens’ attitudes toward science are related to their use of science-related information from various sources. Evidence is scarce regarding citizens’ individual media repertoires for staying informed about science as segmentation studies so far have primarily focused on scientific attitudes. In this paper, we explore audience segments regarding their science-related information behavior and whether such segments are comparable or vary between two countries with similar information environments. Based on two surveys in Switzerland and Germany, we identify national audience segments that differ in their science-related information repertoires, and analyze their sociodemographic characteristics and science-related attitudes. In both countries, we find very comparable information user segments ranging from those who inform themselves frequently about science (“Active Seekers”/“Science Consumers”) to those who hardly get in contact with any information about science and research (“Non-Users”). Those segments which get in contact with information about science frequently show generally more positive attitudes.

description: Fisher information (I) is investigated for confined hydrogen atom (CHA)-like systems in conjugate $r$ and $p$ spaces. A comparative study between CHA and free H atom (with respect to $I$) is pursued. In many aspects, inferences in CHA are significantly different from free counterpart; that includes its dependence on $n, l, m$. The role of atomic number and atomic radius is discussed. Further, a detailed systematic result of $I$ with respect to variation of confinement radius $r_c$ is presented, with particular emphasis on \emph{non-zero}-$(l,m)$ states. Several new interesting observations are recorded. Most of these results are of benchmark quality and presented for the first time.

description: A number of authors have reported filaments connecting bright structures in high-resolution X-ray images, and in some cases these have been taken as evidence for a physical connection between the structures, which might be thought to provide support for a model with non-cosmological redshifts. In this paper I point out two problems which are inherent in the interpretation of smoothed photon-limited data of this kind, and develop some simple techniques for the assessment of the reality of X-ray filaments, which can be applied to either simply smoothed or adaptively smoothed data. To illustrate the usefulness of these techniques, I apply them to archival ROSAT observations of galaxies and quasars previously analysed by others. I show that several reported filamentary structures connecting X-ray sources are not in fact significantly detected.

We develop several robust estimators, some of them being computationally fast modifications of methods of moments, and some rather efficient modifications of conditional maximum likelihood. These estimators are compared to related recent proposals using simulations. The usefulness of the proposed methods is illustrated by a real data example.

description: An effective Proca Lagrangian action is used to address the vector condensation Lorentz violation effects on the equation of state of the strongly interacting fermions system. The interior quantum fluctuation effects are incorporated as an external field approximation indirectly through a fictive generalized Thomson Problem counterterm background. The general analytical formulas for the $d$-dimensions thermodynamics are given near the unitary limit region. In the non-relativistic limit for $d=3$, the universal dimensionless coefficient $ξ={4}/{9}$ and energy gap $Δ/ε_f ={5}/{18}$ are reasonably consistent with the existed theoretical and experimental results. In the unitary limit for $d=2$ and T=0, the universal coefficient can even approach the extreme occasion $ξ=0$ corresponding to the infinite effective fermion mass $m^*=\infty$ which can be mapped to the strongly coupled two-dimensions electrons and is quite similar to the three-dimensions Bose-Einstein Condensation of ideal boson gas. Instead, for $d=1$, the universal coefficient $ξ$ is negative, implying the non-existence of phase transition from superfluidity to normal state. The solutions manifest the quantum Ising universal class characteristic of the strongly coupled unitary fermions gas.

description: We explore the graph approach to contextuality to restate the extended definition of noncontextuality as given by J. Kujala et. al. [Phys. Rev. Lett. 115, 150401 (2015)] using graph-theoretical terms. This extended definition avoids the assumption of the pre-sheaf or non-disturbance condition, which states that if two contexts overlap, then the marginal distribution obtained for the intersection must be the same, a restriction that will never be perfectly satisfied in real experiments. With this we are able to derive necessary conditions for extended noncontextuality for any set of random variables based on the geometrical aspects of the graph approach, which can be tested directly with experimental data in any contextuality experiment and which reduce to traditional necessary conditions for noncontextuality if the non-disturbance condition is satisfied.

description: We show that our Universe may be inhomogeneous on large sub-horizon scales without us being able to realise it. We assume that a network of domain walls permeates the universe dividing it in domains with slightly different vacuum energy densities. We require that the energy scale of the phase transition which produced the domain walls is sufficiently low so that the walls have a negligible effect on structure formation. Nevertheless, the different vacuum densities of different domains will lead to different values of the cosmological parameters $Ω_Λ^0$, $Ω_m^0$ and $h$, in each patch thus affecting the growth of cosmological perturbations at recent times. Hence, if our local patch of the universe (with uniform vacuum density) is big enough -- which is likely to happen given that we should have on average about one domain per horizon volume -- we might not notice these large-scale inhomogeneities. This happens because in order to see a patch with a different vacuum density one may have to look back at a time when the universe was still very homogeneous.

description: The coefficients of different combinations of terms of the liquid drop model have been determined by a least square fitting procedure to the experimental atomic masses. The nuclear masses can also be reproduced using a Coulomb radius taking into account the increase of the ratio $R\_0/A^{1/3}$ with increasing mass, the fitted surface energy coefficient remaining around 18 MeV.

description: We introduce an efficient general method for calculating the self-energies, collective modes, and dispersion relations of quarks and gluons in a momentum-anisotropic high-temperature quark-gluon plasma. The method introduced is applicable to the most general classes of deformed anisotropic momentum distributions and the resulting self-energies are expressed in terms of a series of hypergeometric basis functions which are valid in the entire complex phase-velocity plane. Comparing to direct numerical integration of the self-energies, the proposed method is orders of magnitude faster and provides results with similar or better accuracy. To extend previous studies and demonstrate the application of the proposed method, we present numerical results for the parton self-energies and dispersion relations of partonic collective excitations for the case of an ellipsoidal momentum-space anisotropy. Finally, we also present, for the first time, the gluon unstable mode growth rate for the case of an ellipsoidal momentum-space anisotropy.

description: Background: Chronic pancreatitis (CP) is a leading cause of hospitalization among gastrointestinal diseases resulting in considerable financial burden to patients. However the direct costs for nonsurgical management in CP remains unexplored. Methods: A cross sectional study was carried out (2011–14) in the Department of Gastroenterology, Kasturba Hospital, Manipal, India. Demographic and clinical data on laboratory investigations, interventions and follow up were obtained from the medical records department. Item costs were derived from the hospital electronic billing section. Cost was expressed as median annual cost per patient. Results: 65 (male 48; 73.8%) patients were included. Their median age was 31 (range 12–68) years. The annual median (IQR) total cost per patient was INR 88,892 (70,550.5–116,004); [USD 1410(1119–1841); € 1155(916–1507)], comprising of INR 61,089 (39,102.5–90,360.5) [USD 970 (621–1434); € 793(508–1174)] for outpatient management and INR 32,450 (11,016–46,958) [USD 515 (175–745); €421(143–610)] for hospitalization. 69.5% of the treatment cost was attributed to outpatient treatment. Drugs contributed to 54%, hospitalization incurred 30.5%, investigations 12% and professional fees (3.5%) of the total cost. Pancreatic enzyme replacement therapy (PERT) cost contributed to three-quarters of drug therapy. Use of rabeprazole as against pantoprazole reduced the overall annual cost of therapy by 4%. Conclusions: This study depicts the first nonsurgical management of accrued direct costs associated with CP due to expensive medications. Due to the high cost for PERT, its usefulness needs proper validation by cost benefit analysis.

description: In a framework where galaxies form hierarchically, extended stellar haloes are predicted to be an ubiquitous feature around Milky Way-like galaxies and to consist mainly of the shredded stellar component of smaller galactic systems. The type of accreted stellar systems are expected to vary according to the specific accretion and merging history of a given galaxy, and so is the fraction of stars formed in-situ versus accreted. Analysis of the chemical properties of Milky Way halo stars out to large Galactocentric radii can provide important insights into the properties of the environment in which the stars that contributed to the build-up of different regions of the Milky Way stellar halo formed. In this work we focus on the outer regions of the Milky Way stellar halo, by determining chemical abundances of halo stars with large present-day Galactocentric distances, $>$15 kpc. The data-set we acquired consists of high resolution HET/HRS, Magellan/MIKE and VLT/UVES spectra for 28 red giant branch stars covering a wide metallicity range, $-3.1 \lesssim$[Fe/H]$\lesssim -0.6$. We show that the ratio of $α$-elements over Fe as a function of [Fe/H] for our sample of outer halo stars is not dissimilar from the pattern shown by MW halo stars from solar neighborhood samples. On the other hand, significant differences appear at [Fe/H]$\gtrsim -1.5$ when considering chemical abundance ratios such as [Ba/Fe], [Na/Fe], [Ni/Fe], [Eu/Fe], [Ba/Y]. Qualitatively, this type of chemical abundance trends are observed in massive dwarf galaxies, such as Sagittarius and the Large Magellanic Cloud. This appears to suggest a larger contribution in the outer halo of stars formed in an environment with high initial star formation rate and already polluted by asymptotic giant branch stars with respect to inner halo samples.

description: No abstracts are to be cited without prior reference to the author.FRS Marine Laboratory, Aberdeen, is responsible for the licensing of deposition of wastes such as dredged spoils in UK waters adjacent to Scotland, under Part II of the Food and Environment Protection Act 1985. This includes the chemical assessment of potential deposits as well as assessment of the locations after deposition. Dredged harbour sediments being considered for disposal at sea are traditionally analysed for total concentrations of PAHs, CBs and metals and are assessed based on sediment quality criteria or guidelines. As part of the progressive development of the licensing process, FRS has assessed the availability of PAHs in dredged sediments collected from 6 locations in the Firth of Clyde, Scotland, UK (which, due to industrial and domestic inputs is arguably considered Scotland’s most contaminated water body) using silicone rubber passive samplers, following protocols developed through the ICES Working Group on Marine Sediments. Comparison of the concentrations of PAHs in pore water is made with sediment collected from Telford Dock, Aberdeen harbour (a busy harbour for vessels linked with the North Sea oil and gas and fishing industry as well as ferries to and from the Northern Isles), UK. Pore water concentrations in sediments from the Clyde ranged from 2.10 (dibenz[a,h]anthracene) – 65,105 (2,6-dimethylnaphthalene) pg L-1 and these were factors of 0.5 to 7.1 higher than the concentrations found in Aberdeen harbour.

description: Inclusive cross section for pion production in proton - proton collisions are calculated based on unintegrated parton distribution functions (uPDFs). In addition to purely gluonic terms the present approach includes also quark degrees of freedom. Phenomenological fragmentation functions from the literature are used. The new mechanisms are responsible for $π^+$ - $π^-$ asymmetry. In contrast to standard collinear approach, application of 2 $\to$ 1 $k_t$ - factorization approach can be extended towards much lower transverse momenta, both at mid and forward rapidity region. The results of the calculation are compared with SPS and RHIC data.
