description: We incorporate non-thermal excitation and ionization processes arising from non-thermal electrons that result from γ-ray energy deposition, into our radiative transfer code CMFGEN. The non-thermal electron distribution is obtained by solving the Spencer-Fano equation using the procedure of Kozma & Fransson (1992). We applied the non-thermal calculations to the blue supergiant explosion model whose early evolution was studied in Dessart & Hillier (2010). Non-thermal processes generally increase excitation and ionization and decrease the temperature of the ejecta. We confirm that non-thermal processes are crucial for modeling the nebular spectra. Both optical HI and HeI lines are significantly strengthened. While optical HeI lines are not easily discerned in observational spectra due to severe blending with other lines, HeI 2.058 μm provides an excellent opportunity to infer the influence of non-thermal processes. We also discuss the processes controlling the formation of the HeI lines during the nebular epoch. Most lines of other species are only slightly affected. We also show that the inclusion of FeI has substantial line-blanketing effects on the optical spectra. Our model spectra and synthetic light curves are compared to the observations of SN 1987A. The spectral evolution shows broad agreement with the observations, especially Hα. The uncertainties of the non-thermal solver are studied, and are expected to be small. With this new addition of non-thermal effects in CMFGEN, we now treat all known important processes controlling the radiative transfer of a supernova ejecta, whatever the type and the epoch.

description: A microwave ultra-broadband polarization-independent metamaterial absorber is demonstrated. It is composed of a periodic array of metal-dielectric multilayered quadrangular frustum pyramids. These pyramids possess resonant absorption modes at multi-frequencies, of which the overlapping leads to the total absorption of the incident wave over an ultra-wide spectral band. The experimental absorption at normal incidence is above 90% in the frequency range of 7.8-14.7GHz, and the absorption is kept large when the incident angle is smaller than 60 degrees. The experimental results agree well with the numerical simulation.

description: Non-traditional stable isotopes of metals were recently shown as new dietary tracers in terrestrial and marine mammals. Whether these metal stable isotopes can be used to understand feeding habits in stream food webs is not known yet. In this study, we explored the potential of stable isotopes of essential Mg (δ²⁶Mg) and Zn (δ⁶⁶Zn) as a new tool in stream ecology. For this purpose, we determined δ²⁶Mg and δ⁶⁶Zn values of stream organisms and their potential metal sources in upper and lower reaches of two streams in the Lake Biwa catchment, Central Japan. Our goals were (1) to explore variations in δ²⁶Mg and δ⁶⁶Zn across organisms of different feeding habits and (2) to understand Mg and Zn sources to stream organisms. Overall, δ²⁶Mg and δ⁶⁶Zn values of organisms were neither related to each other, nor to δ¹³C and δ¹⁵N values, indicating different elemental sources and factors controlling isotopic fractionation depending on element and taxa. Low δ²⁶Mg values in filter-feeding caddisfly larvae and small gobies indicated aqueous Mg uptake. Higher δ²⁶Mg values in leaf-shredding crane fly and grazing mayfly larvae suggested Mg isotopic fractionation during Mg uptake from the diet. While the δ²⁶Mg values of stonefly nymphs reflected those of caddisfly larvae as a potential prey, the highest δ²⁶Mg values found in dobsonfly nymphs can be explained by ²⁶Mg enrichment during maturing. δ⁶⁶Zn values of caddisfly and mayfly larvae indicated Zn was a mixture of aqueous and dietary available Zn, while higher δ⁶⁶Zn values in crane fly larvae pointed to Zn isotopic fractionation during Zn uptake from plant litter. δ⁶⁶Zn values in stonefly and dobsonfly nymphs were often in the range of those of caddisfly larvae as their prey, while dragonfly nymphs and small goby were depleted in ⁶⁶Zn relative to their dietary Zn sources. We conclude that δ²⁶Mg is a promising indicator to assess Mg sources in stream ecology depending on taxa, while the use of δ⁶⁶Zn is limited due to the complexity in Zn sources.

description: We develop a perturbative approach to study the supersymmetric non-linear sigma model characterized by a generic coupling matrix in the strong coupling limit. The method allows us to calculate explicitly the moments of the eigenfunctions and the two-level correlation function in the lowest order of the perturbative expansion. We find that the obtained expressions are equivalent to the results derived before for the corresponding random matrix ensembles. Such an equivalence is elucidated and generalized to all orders of the perturbative expansion by mapping the sigma model onto the field theory describing the almost diagonal random matrices.

Observing The Cosmic Microwave Background Polarization Anisotropy At 40 Ghz With Quiet

description: The Cosmic Microwave Background has proven to be an invaluable tool for cosmology, but much of the scientific information contained in its polarization anisotropy is still to be discovered. Of particular interest is the angular power spectrum of the tiny B-mode polarization signal, the divergence free component which is geometrically distinct from the dominant E-modes. The theory of inflation, which has been proposed to explain several curious features of our universe, predicts the existence of B-mode fluctuations on large angular scales and at a signal level that may be achievable in the near future.

The Q/U Imaging Experiment (QUIET) is designed to make sensitive measurements of the CMB polarization using arrays of integrated "detectors on a chip" that can be scaled to reach the sensitivity requirements for detecting B-modes.

This thesis covers the design of QUIET, which consists of separate instruments for observation at 40 and 90 GHz. After the discussion of the detectors, which generally applies to both instruments, the remaining sections focus on observations, calibration, and data analysis for the 40 GHz detector. Tests performed on the data indicate some not-yet-identified source of contamination that must be understood and corrected before a reliable result can be obtained.

description: Motivated by evidence for the existence of dark matter, many new physics models predict the pair production of new particles, followed by the decays into two invisible particles, leading to a momentum imbalance in the visible system. For the cases where all four components of the vector sum of the two `missing' momenta are measured from the momentum imbalance, we present analytic solutions of the final state system in terms of measureable momenta, with the mass shell constraints taken into account. We then introduce new variables which allow the masses involved in the new physics process, including that of the dark matter particles, to be extracted. These are compared with a selection of variables in the literature, and possible applications at lepton and hadron colliders are discussed.

Formaldehyde Silhouettes Against the Cosmic Microwave Background: A Mass-Limited, Distance-Independent, Extinction-Free Tracer of Star Formation Across the Epoch of Galaxy Evolution

description: We examine the absorption of cosmic microwave background (CMB) photons by formaldehyde (H2CO) over cosmic time. The K-doublet rotational transitions of H2CO become "refrigerated" - their excitation temperatures are driven below the CMB temperature - via collisional pumping by molecular hydrogen (H2). "Anti-inverted" H2CO line ratios thus provide an accurate measurement of the H2 density in molecular clouds. Using a radiative transfer model, we demonstrate that H2CO centimeter wavelength line excitation and detectability are nearly independent of redshift or gas kinetic temperature. Since the H2CO K-doublet lines absorb CMB light, and since the CMB lies behind every galaxy and provides an exceptionally uniform extended illumination source, H2CO is a distance-independent, extinction-free molecular gas mass-limited tracer of dense gas in galaxies. A Formaldehyde Deep Field could map the history of cosmic star formation in a uniquely unbiased fashion and may be possible with large bandwidth wide-field radio interferometers whereby the silhouettes of star-forming galaxies would be detected across the epoch of galaxy evolution. We also examine the possibility that H2CO lines may provide a standardizable galaxy ruler for cosmology similar to the Sunyaev-Zel'dovich effect in galaxy clusters but applicable to much higher redshifts and larger samples. Finally, we explore how anti-inverted meterwave H2CO lines in galaxies during the peak of cosmic star formation may contaminate HI 21 cm tomography of the Epoch of Reionization.

The best prediction for sea level in the future is simply a linear projection of the history of sea level at the same location in the past. For Long Island, that is about 7-8 inches by 2080.

description: Many historians of the calculus deny significant continuity between infinitesimal calculus of the 17th century and 20th century developments such as Robinson's theory. Robinson's hyperreals, while providing a consistent theory of infinitesimals, require the resources of modern logic; thus many commentators are comfortable denying a historical continuity. A notable exception is Robinson himself, whose identification with the Leibnizian tradition inspired Lakatos, Laugwitz, and others to consider the history of the infinitesimal in a more favorable light. Inspite of his Leibnizian sympathies, Robinson regards Berkeley's criticisms of the infinitesimal calculus as aptly demonstrating the inconsistency of reasoning with historical infinitesimal magnitudes. We argue that Robinson, among others, overestimates the force of Berkeley's criticisms, by underestimating the mathematical and philosophical resources available to Leibniz. Leibniz's infinitesimals are fictions, not logical fictions, as Ishiguro proposed, but rather pure fictions, like imaginaries, which are not eliminable by some syncategorematic paraphrase. We argue that Leibniz's defense of infinitesimals is more firmly grounded than Berkeley's criticism thereof. We show, moreover, that Leibniz's system for differential calculus was free of logical fallacies. Our argument strengthens the conception of modern infinitesimals as a development of Leibniz's strategy of relating inassignable to assignable quantities by means of his transcendental law of homogeneity.

description: Wie bereits in einem früheren
      Policy Paper dargestellt, haben sich die Umbruchprozesse der
      MENA-Region von 2011 nicht nur in den Nationalstaaten selbst,
      sondern auch auf inter- und intraregionaler Ebene ausgewirkt.
      Auffälliger Indikator für die regionalpolitischen
      Umstrukturierungen war die Herausbildung von zwei
      Aktionsachsen, die zur zwischenzeitlichen Konstituierung von
      konkurrierenden Gravitationszentren entlang des Phänomens des
      moderaten Islamismus geführt hatte. Bis Juni 2015 haben sich
      regionale Konstellationen von Machtstrukturen, die sich durch
      die Systemveränderungen seit 2011 abgezeichnet und durch die
      Amtsenthebung Mohamed Mursis weiter akzentuiert hatten,
      erneut re-konfiguriert. Dies umfasst sowohl Kooperations-,
      als auch Konkurrenzverhältnisse der Staaten des Nahen Ostens,
      die nach wie vor einer permanenten Neuaushandlung unterworfen
      sind. Vor diesem Hintergrund soll analysiert werden,
      inwiefern sich die geopolitischen Machtverhältnisse in der
      Region des Mittleren Ostens verändert haben und es sich bei
      dem Phänomen des moderaten Islamismus weiterhin um einen
      zentralen Faktor in diesen Aushandlungsprozessen von

      die Beeinflussung der Re-Konfigurationen staatlicher Ordnung

      wird eine kurze Bestandsaufnahme über die Rolle des moderaten
      Islamismus als zentrale Determinante von Außen- und
      Interessenpolitiken unterschiedlicher Staaten des Nahen
      Ostens seit Beginn der systemischen Umbruchprozesse in der
      MENA-Region von 2011 vorgenommen. Auf dieser Grundlage werden
      an den Beispielen des Verhältnisses der Regionalstaaten
      gegenüber Iran und der Ausweitung der Organisation
      „Islamischer Staat“ (IS)exemplarisch zwei gewichtige
      Bedrohungsszenarien aufgezeigt, die Einfluss auf die
      Neuverhandlung der Region haben. Empirische Grundlagen für
      die Analyse bilden Auswertungen von unterschiedlichen
      Schriftdokumenten, Hintergrundgesprächen und Interviews, die

The identification of an electromagnetic counterpart could provide a more complete understanding of a gravitational wave event, including such characteristics as the location and the nature of the progenitor. We used the Expanded Very Large Array (EVLA) to search six galaxies which were identified as potential hosts for two candidate gravitational wave events. We summarize our procedures and discuss preliminary results.

description: Muon spin rotation (μ+SR) measurements of square-root second moments of local magnetic fields σ in superconducting mixed states, as published for oriented crystals and powder samples of YBa2Cu3O7-δ (δ {\approx} 0.05), YBa2Cu4O8 and La2-xSrxCuO4 (x ~ 0.15-0.17), are subjected to comparative analysis for superconducting gap symmetry. For oriented crystals it is shown that anomalous dependences of σ on temperature T and applied field H, as-measured and extracted a- and b-axial components, are attributable to fluxon depinning and disorder that obscure the intrinsic character of the superconducting penetration depth. Random averages derived from oriented-crystal data differ markedly from corresponding non-oriented powders, owing to weaker influence of pinning in high-quality crystals. Related indicators for pinning perturbations such as non-monotonic H dependence of σ, irreproducible data and strong H dependence of apparent transition temperatures are also evident. Strong intrinsic pinning suppresses thermal anomalies in c-axis components of σ, which reflect nodeless gap symmetries in YBa2Cu3O7-δ and YBa2Cu4O8. For YBa2Cu3O7-δ, the crystal (a-b components, corrected for depinning) and powder data all reflect a nodeless gap (however, a-b symmetries remain unresolved for crystalline YBa2Cu4O8 and La1.83Sr0.17CuO4). Inconsistencies contained in multiple and noded gap interpretations of crystal data, and observed differences between bulk μ+SR and surface-sensitive measurements are discussed.

description: This paper presents measurements of charged-hadron spectra obtained in $pp$, $p$+Pb, and Pb+Pb collisions at $\sqrt{s}$ or $\sqrt{s_{_\text{NN}}}=5.02$ TeV, and in Xe+Xe collisions at $\sqrt{s_{_\text{NN}}}=5.44$ TeV. The data recorded by the ATLAS detector at the LHC have total integrated luminosities of 25 pb${}^{-1}$, 28 nb${}^{-1}$, 0.50 nb${}^{-1}$, and 3 $\mu$b${}^{-1}$, respectively. The nuclear modification factors $R_{p\text{Pb}}$ and $R_\text{AA}$ are obtained by comparing the spectra in heavy-ion and $pp$ collisions in a wide range of charged-particle transverse momenta and pseudorapidity. The nuclear modification factor $R_{p\text{Pb}}$ shows a moderate enhancement above unity with a maximum at $p_{\mathrm{T}} \approx 3$ GeV; the enhancement is stronger in the Pb-going direction. The nuclear modification factors in both Pb+Pb and Xe+Xe collisions feature a significant, centrality-dependent suppression. They show a similar distinct $p_{\mathrm{T}}$-dependence with a local maximum at $p_{\mathrm{T}} \approx 2$ GeV and a local minimum at $p_{\mathrm{T}} \approx 7$ GeV. This dependence is more distinguishable in more central collisions. No significant $|\eta|$-dependence is found. A comprehensive comparison with several theoretical predictions is also provided. They typically describe $R_\text{AA}$ better in central collisions and in the $p_{\mathrm{T}}$ range from about 10 to 100 GeV.

description: Re-entrance is a novel feature where the phase boundaries of a system exhibit a succession of transitions between two phases A and B, like A-B-A-B, when just one parameter is varied monotonically. This type of re-entrance is displayed by the 1D Bose Hubbard model between its Mott insulator (MI) and superfluid phase as the hopping amplitude is increased from zero. Here we analyse this counter-intuitive phenomenon directly in the thermodynamic limit by utilizing the infinite time-evolving block decimation algorithm to variationally minimize an infinite matrix product state (MPS) parameterized by a matrix size chi. Exploiting the direct restriction on the half-chain entanglement imposed by fixing chi, we determined that re-entrance in the MI lobes only emerges in this approximate when chi >= 8. This entanglement threshold is found to be coincident with the ability an infinite MPS to be simultaneously particle-number symmetric and capture the kinetic energy carried by particle-hole excitations above the MI. Focussing on the tip of the MI lobe we then applied, for the first time, a general finite-entanglement scaling analysis of the infinite order Kosterlitz-Thouless critical point located there. By analysing chi's up to a very moderate chi = 70 we obtained an estimate of the KT transition as t_KT = 0.30 +/- 0.01, demonstrating the how a finite-entanglement approach can provide not only qualitative insight but also quantitatively accurate predictions.

description: Linking scientific instruments to exascale machines and analyzing the large volumes of data produced by the instruments requires workflow infrastructure that scales along many dimensions. In this white paper we generalize this problem to include control systems, analysis of data produced by supercomputers, computational steering and data assimilation. The requirements of distributed computing problems which couple HPC and streaming data, are distinct from those familiar from large­scale parallel simulations, grid computing, data repositories and orchestration, which have generated sophisticated software platforms. Our analyses points to new research directions for a scalable infrastructure, to address this generalized streaming distributed workflows problem class.

description: Black-hole spacetimes with a "photonsphere", a hypersurface on which massless particles can orbit the black hole on circular null geodesics, are studied. We prove that among all possible trajectories (both geodesic and non-geodesic) which circle the central black hole, the null circular geodesic is characterized by the {\it shortest} possible orbital period as measured by asymptotic observers. Thus, null circular geodesics provide the fastest way to circle black holes. In addition, we conjecture the existence of a universal lower bound for orbital periods around compact objects (as measured by flat-space asymptotic observers): $T_{\infty}\geq 4πM$, where $M$ is the mass of the central object. This bound is saturated by the null circular geodesic of the maximally rotating Kerr black hole.

description: Let $H=-Δ+V$, where $V$ is a real valued potential on $\R^2$ satisfying $|V(x)|\les \la x\ra^{-3-}$. We prove that if zero is a regular point of the spectrum of $H=-Δ+V$, then $$ \|w^{-1} e^{itH}P_{ac}f\|_{L^\infty(\R^2)}\les \f1{|t|\log^2(|t|)} \|w f\|_{L^1(\R^2)}, |t| >2, $$ with $w(x)=\log^2(2+|x|)$. This decay rate was obtained by Murata in the setting of weighted $L^2$ spaces with polynomially growing weights.

description: The magnetic properties of single-crystal EuTiO3 are suggestive of nanoscale disorder below its cubic-tetragonal phase transition. We demonstrate that electric field cooling acts to restore monocrystallinity, thus confirming that emergent structural disorder is an intrinsic low-temperature property of this material. Using torque magnetometry, we deduce that tetragonal EuTiO3 enters an easy-axis antiferromagnetic phase at 5.6 K, with a first-order transition to an easy-plane ground state below 3 K. Our data is reproduced by a 3D anisotropic Heisenberg spin model.

description: In-medium ${\bar K}N$ scattering amplitudes developed within a new chirally motivated coupled-channel model due to Cieply and Smejkal that fits the recent SIDDHARTA kaonic hydrogen 1s level shift and width are used to construct $K^-$ nuclear potentials for calculations of $K^-$ nuclear quasi-bound states. The strong energy and density dependence of scattering amplitudes at and near threshold leads to $K^-$ potential depths $-Re V_K \approx 80 -120$ MeV. Self-consistent calculations of all $K^-$ nuclear quasi-bound states, including excited states, are reported. Model dependence, polarization effects, the role of p-wave interactions, and two-nucleon $K^-NN\rightarrow YN$ absorption modes are discussed. The $K^-$ absorption widths $Γ_K$ are comparable or even larger than the corresponding binding energies $B_K$ for all $K^-$ nuclear quasi-bound states, exceeding considerably the level spacing. This discourages search for $K^-$ nuclear quasi-bound states in any but lightest nuclear systems.

description: Understanding electron transport processes in molecular wires connected between contacts is a central focus in the field of molecular electronics. Especially, the dephasing effect causing tunneling-to-hopping transition has great importance from both applicational and fundamental points of view. We analyzed coherent and incoherent electron transmission through conjugated molecular wires by means of density-functional tight-binding theory within the D'Amato-Pastawski model. Our approach can study explicitly the structure/transport relationship in molecular junctions in a dephasing environmental condition using only single dephasing parameter. We investigated the length dependence and the influence of thermal fluctuations on transport and reproduced the well-known tunneling-to-hopping transition. This approach will be a powerful tool for the interpretation of recent conductance measurements of molecular wires.

description: Нашими исследованиями обнаружено, что развитие и становление надпочечников происходят в этапах раннего постнатального периода и подчинена определённой закономерности и динамике. Она во многом имеет сходство с динамикой развития, характерной и описанной для других переферических эндокринных желёз, и это указывает на общие принципы регуляторных механизмов в развитие и формировании в постнатальный период развития для органов периферической эндокринной системы.

description: Depuis quelques années, à l'Université d'Ottawa, une grande partie des étudiants et étudiantes en enseignement arrivent d'Afrique subsaharienne. Bien que la plupart réussisse ses stages, la littérature recensée analyse surtout les difficultés rencontrées. Cette étude se situe dans la recherche qualitative interprétative. Elle adopte l'approche interactionniste et la notion d'expérience de Dewey. Suivant la méthode de Morissette et Demazière (2019), deux stagiaires d'Afrique subsaharienne ont été invitées à un « entretien individuel à orientation biographique » (p. 53), puis à trois entretiens collectifs entre elles et moi. En s'inspirant des auteurs, les stagiaires et moi-même avons interprété et co-analysé les expériences et les incidents critiques vécus dans le milieu de stage. La méthode des incidents critiques et les entrevues semi-dirigés ont montré qu'un stage réussi ne signifie pas nécessairement que la stagiaire interprète son expérience de façon positive. En somme, l'analyse montre la grande complexité de l'expérience de stage, façonnée par la vulnérabilité induite par la négociation de schèmes d'interprétation au travers l'interaction des stagiaires avec leur enseignant-accompagnateur.

description: This report contains the analyses and findings of the Alaska Fisheries Science Center’s Fisheries Monitoring and Analysis Division’s Observer Science Committee on the efficiency and effectiveness of observer deployment in 2014. This review is performed as part of the annual review process implemented by the North Pacific Fishery Management Council for the North Pacific Groundfish and Halibut Observer Program. This report is intended to inform the Council, the National Marine Fisheries Service (NMFS), and the public how well various aspects of the observer program are working, and it contains recommendations for improvement. Several performance metrics were evaluated. These included metrics that assess whether targeted levels of observer coverage were achieved, metrics that assess whether data from the observed fleet was representative of the unobserved fleet, and metrics that evaluated the probability of obtaining data throughout the fleet given the current sample rate (deployment rate). Observer deployments are representative if they are not spatially or temporally biased and if the characteristics of observed trips are similar to those from unobserved trips. Non-representative spatial or temporal deployments are evidence of a deployment effect and differences between the observed and unobserved fleet fishing characteristics are evidence of an observer effect. This evaluation of observer deployment was conducted at the stratum level as defined in the 2014 Annual Deployment Plan (ADP; released in December of 2013), since each stratum is defined by its own sampling unit (i.e., vessels or trips) and/or rate of sampling...

description: This report, the second of its kind from ASINA project, aims at providing a roadmap with quantitative metrics for Safe(r) and (more) Sustainable by Design (SSbD) solutions for titanium dioxide (TiO2) nanomaterials (NMs). We begin with a brief description of ASINA’s methodology across the product lifecycle, highlighting the quantitative elements, such as the Key Performance Indicators (KPIs). We then propose a decision support tool for implementing SSbD objectives across various dimensions—functionality, cost, environment, and human health safety. This is followed by the main innovative findings, a consolidation of the technical processes involved, design rationales, experimental procedures, tools and models, used and developed, to deliver photocatalytic depolluting surfaces by spray- finishing techniques based on TiO2 NMs formulations. The roadmap is thoroughly described to inform similar projects through the integration of KPIs into SSbD methodologies, fostering data-driven decision making. While specific results are beyond this report’s scope, its primary aim is to demonstrate the roadmap (SSbD know-how) and promote SSbD-oriented innovation in nanotechnology. Finally, we provide a comparison of the approaches followed in two case studies that target different industrial sectors. This case-specific SSbD assessments provide a concrete exemplification of the addressed methodology that contributes to the efforts towards attaining a common roadmap for implementing SSbD solutions aligned with the EU’s Green Deal objectives
