description: We present first results from the Southern Cosmology Survey, a new multiwavelength survey of the southern sky coordinated with the Atacama Cosmology Telescope (ACT), a recently commissioned ground-based mm-band Cosmic Microwave Background experiment. This article presents a full analysis of archival optical multi-band imaging data covering an 8 square degree region near right ascension 23 hours and declination -55 degrees, obtained by the Blanco 4-m telescope and Mosaic-II camera in late 2005. We describe the pipeline we have developed to process this large data volume, obtain accurate photometric redshifts, and detect optical clusters. Our cluster finding process uses the combination of a matched spatial filter, photometric redshift probability distributions and richness estimation. We present photometric redshifts, richness estimates, luminosities, and masses for 8 new optically-selected clusters with mass greater than $3\times10^{14}M_{\sun}$ at redshifts out to 0.7. We also present estimates for the expected Sunyaev-Zel'dovich effect (SZE) signal from these clusters as specific predictions for upcoming observations by ACT, the South Pole Telescope and Atacama Pathfinder Experiment.

description: In den vergangenen Jahren kommen internationale wie nationale Untersuchungen zu Beziehungen zwischen Lehrkräften und Schüler*innen zu dem Ergebnis, dass ein tragfähiges Lehrer*innen-Schüler*innen-Verhältnis nicht nur statistisch signifikante Effekte auf die Leistungs- und Persönlichkeitsentwicklung der Schüler*innen, sondern auch auf die Selbstwirksamkeit und Motivation der Lehrkräfte hat (u. a. Kuhn & Fischer, 2014; Klassen, Perry & Frenzel, 2012; Spilt, Koomen & Thijs, 2011; Drucks, Osipov & Quenzel, 2010; Baumert & Kunter, 2006). Insbesondere für Schulen in herausfordernder Lage verweisen jüngste Studien vor dem Hintergrund von Bildungsgerechtigkeit auf die Bedeutsamkeit der Beziehungsebene (u. a. Bremm, 2019; Racherbäumer & van Ackeren, 2015; Rutledge, Cohen-Vogel, Osborne-Lampkin & Roberts, 2015; Smyth 2014; Stojanow, 2013). Ein positives Verhältnis zwischen Lehrkräften und Schüler*innen stellt somit nachweisbar einen Zugewinn für beide Seiten dar und sollte für alle Beteiligten erstrebenswert sein. Für die Schulentwicklungsarbeit bedeutet dies, dass Schulen notwendigerweise ein Programm zur Veränderung der Lehrer*innen-Schüler*innen-Beziehungen mitbringen müssen, dessen Einlösung auch empirisch überprüft werden kann.

description: We use N-body simulations to explore the origin and a plausible orbit for the Orphan Stream, one of the faintest substructures discovered so far in the outer halo of our Galaxy. We are able to reproduce its position, velocity and distance measurements by appealing to a single wrap of a double-component satellite galaxy. We find that the progenitor of the Orphan Stream could have been an object similar to today's Milky Way dwarfs, such as Carina, Draco, Leo II or Sculptor; and unlikely to be connected to Complex A or Ursa Major II. Our models suggest that such progenitors, if accreted on orbits with apocenters smaller than ~35 kpc, are likely to give rise to very low surface brightness streams, which may be hiding in the outer halo and remain largely undetected with current techniques. The systematic discovery of these ghostly substructures may well require wide field spectroscopic surveys of the Milky Way's outer stellar halo.

description: The Alice ultraviolet spectrograph on board the \textit{Rosetta} orbiter provided the first near-nucleus ultraviolet observations of a cometary coma from arrival at comet 67P/Churyumov-Gerasimenko in 2014 August through 2016 September. The characterization of atomic and molecular emissions in the coma revealed the unexpected contribution of dissociative electron impact emission at large heliocentric distances and during some outbursts. This mechanism also proved useful for compositional analysis, and Alice observed many cases that suggested elevated levels of the supervolatile \ce{O2}, identifiable in part to their emissions resulting from dissociative electron impact. In this paper we present the first two-dimensional UV maps constructed from Alice observations of atomic emission from 67P during an increase in cometary activity on 2015 November 7-8. Comparisons to observations of background coma and of an earlier collimated jet are used to describe possible changes to the near-nucleus coma and plasma. To verify the mapping method and place the Alice observations in context, comparisons to images derived from the MIRO and VIRTIS-H instruments are made. The spectra and maps we present show an increase in dissociative electron impact emission and an \ce{O2}/\ce{H2O} ratio of $\sim$0.3 for the activity; these characteristics have been previously identified with cometary outbursts seen in Alice data. Further, UV maps following the increases in activity show the spatial extent and emission variation experienced by the near-nucleus coma, informing future UV observations of comets that lack the same spatial resolution.

description: Spontaneous and induced fission in Special Nuclear Material (SNM) such as 235U and 239Pu results in the emission of neutrons and high energy gamma-rays. The multiplicities of and time correlations between these particles are both powerful indicators of the presence of fissile material. Detectors sensitive to these signatures are consequently useful for nuclear material monitoring, search, and characterization. In this article, we demonstrate sensitivity to both high energy gamma-rays and neutrons with a water Cerenkov based detector. Electrons in the detector medium, scattered by gamma-ray interactions, are detected by their Cerenkov light emission. Sensitivity to neutrons is enhanced by the addition of a gadolinium compound to the water in low concentrations. Cerenkov light is similarly produced by an 8 MeV gamma-ray cascade following neutron capture on the gadolinium. The large solid angle coverage and high intrinsic efficiency of this detection approach can provide robust and low cost neutron and gamma-ray detection with a single device.

Interactive polygon filling on a raster graphic display

Publisher: name: University of British Columbia
Year: 2010

description: This thesis describes Polygon Filling System, an interactive graphics system, which fills user defined areas on a raster scan graphics display device. The areas may be concave or convex and may be nested within each other. Issues related to the underlying grid model, hexagonal or square tesselation, are discussed. A formal approach to polygon filling is compared to a heuristic domain dependent approach. Connectivity problems arise in processing boundaries. Two user rules are defined. Adherence to these rules ensures correct processing of data. These rules are appropriate for cartographic and remote sensing applications. The implementation of the system and its key data structures are described.

description: We compare the main feature of the measured Raman scattering spectra from single layer graphene with a bilayer in which the two layers are arbitrarily misoriented. The profiles of the 2D bands are very similar having only one component, contrary to the four found for commensurate Bernal bilayers. These results agree with recent theoretical calculations and point to the similarity of the electronic structures of single layer graphene and misoriented bilayer graphene. Another new aspect is that the dependance of the 2D frequency on the laser excitation energy is different in these two latter systems.

description: In theoretical models of galaxy evolution, AGN and star formation (SF) activity are closely linked and AGN feedback is routinely invoked to regulate galaxy growth. In order to constrain such models, we compare the hydrodynamical simulations IllustrisTNG and SIMBA, and the semi-analytical model SAG to the empirical results on AGN and SF at cosmic noon ($0.75 < z < 2.25$) reported in Florez et al. (2020). The empirical results are based on a large mass-complete sample drawn from 93,307 galaxies with and without high X-ray luminosity AGN ($L_X \gtrsim 10^{44}$ erg s$^{-1}$), selected from a 11.8 deg$^2$ area ($\sim 0.18$ Gpc$^3$ comoving volume at $z=0.75-2.25$). The main results of our comparisons are: (i) SAG and IllustrisTNG both qualitatively reproduce the empirical result that galaxies with high X-ray luminosity AGN have higher mean SFR, at a given stellar mass, than galaxies without such AGN. SAG, however, strongly over-produces the number density of high X-ray luminosity AGN by a factor of 10 to 100, while IllustrisTNG shows a lack of high X-ray luminosity AGN at high stellar mass ($M* > 10^{11} \ M_{\odot}$) at $z \sim 2$. (ii) In SIMBA, the mean SFR of galaxies with high X-ray luminosity AGN is lower than the SFR of galaxies without such AGN. Contrary to the data, many high X-ray luminosity AGN in SIMBA have quenched SF, suggesting that AGN feedback, or other feedback modes in galaxies with such AGN, might be too efficient in SIMBA.

description: This is the first report, to our knowledge, on a systematic method for constructing a large scale kinetic metabolic model with incomplete information on kinetic parametersr, and its initial application to the modeling of central metabolism of Methylobacterium extorquens AM1, a methylotrophic and environmental important bacterium, with all necessary constraints. Through a systematic and consistent procedure of finding a set of parameters in the physiological range we overcome an outstanding difficulty in large scale kinetic modeling: the requirement for a massive number of enzymatic reaction parameters. We are able to construct the kinetic model based on general biological considerations and incomplete experimental kinetic parameters. The success of our approach with incompletely input information is guaranteed by two known principles in biology, the robustness of the system and the cooperation among its various parts.

Die Programmatik des Forschungs- und Interventionsprojekts zielt unter anderem auf Reflexion von Defizitorientierung sowie auf ihre Überschreibung durch kommunikative Evidenz und Selbstwirksamkeitserfahrungen. Nun zeigte eine selbst entwickelte Skala über die Projektlaufzeit (Messzeitpunkt 1=2014 bis Messzeitpunkt 2=2018) nicht statistischen Rückgang, sondern Zunahme von Defizitorientierung über alle Gruppen (Schulformen, Standorttypen, Netzwerke etc.) hinweg.

description: Thyridinae 1055 * R Thyris maculata Harris, 1839 T: Covell (1984) L: None C: UASM M Jun – L Jun m – G Section 2. Butterflies The butterflies have received considerable attention because of their conspicuous nature. As a result, they are relatively well known, and a vast literature is available for technical and popular audiences. In North America, very few species remain undescribed. However, uncertainty remains about the status of many taxa; some subspecies may prove to be valid species, and there is considerable debate about the status and composition of several genera. As a result, the accepted scientific names of the taxa listed here vary from one publication to another. Th e higher classification used here is based on Pelham (2008), which is expected to become the standard classification for the forseeable future. The butterflies comprise three superfamilies, the Hesperioidea, the Papilionoidea, and the Hedyloidea, which are phylogenetically embedded within the moths. Approximately 17 500 species are known worldwide; this group is particularly diverse in the tropics. Th e superfamily Hedyloidea occurs only in Central and South America. About 800 species of butterflies are known in North America north of Mexico; 175 species are reported from AB. The butterflies of AB have been treated by Bird et al. (1995) and Layberry et al. (1998). A large number of the taxa listed here were also covered in detail by Guppy and Shepard (2001). Th ese references are not listed in the taxonomy sections for the families or the individual species; all three of them are relevant to almost every species listed, and should be consulted in addition to the other references cited.

description: Theoretical issues are discussed for the measurement of the top-mass using jets, including perturbative and non-perturbative effects that relate experimental observables to the Lagrangian mass, and appropriate choices for mass schemes. Full account for these issues is given for e+e--> t-tbar using a factorization theorem for event shapes for massive quarks. Implications for the Tevatron top-mass measurement are discussed. A mass-scheme, the "MSR-mass", is introduced which allows for a precise description of observables sensitive to scales R << m, but at the same time does not introduce perturbative matching uncertainties in conversion to the MSbar mass.

description: Metamagnetism in layered ruthenates has been interpreted as a novel kind of quantum critical behavior. In an external magnetic field, Ca$_{2-x}$Sr$_x$RuO$_4$ undergoes a metamagnetic transition accompanied by a pronounced magnetostriction effect. In this paper we present a mean-field study for a microscopic model that naturally reproduces the key features of this system. The phase diagram calculated is equivalent to the experimental $T$-$x$ phase diagram. The presented model also gives a good basis to discuss the critical metamagnetic behavior measured in the system.

description: Diffraction microtomography in coherent light is foreseen as a promising technique to image transparent living samples in three dimensions without staining. Contrary to conventional microscopy with incoherent light, which gives morphological information only, diffraction microtomography makes it possible to obtain the complex optical refractive index of the observed sample by mapping a three-dimensional support in the spatial frequency domain. The technique can be implemented in two configurations, namely, by varying the sample illumination with a fixed sample or by rotating the sample using a fixed illumination. In the literature, only the former method was described in detail. In this report, we precisely derive the three-dimensional frequency support that can be mapped by the sample rotation configuration. We found that, within the first-order Born approximation, the volume of the frequency domain that can be mapped exhibits a missing part, the shape of which resembles that of an apple core. The projection of the diffracted waves in the frequency space onto the set of sphere caps covered by the sample rotation does not allow for a complete mapping of the frequency along the axis of rotation due to the finite radius of the sphere caps. We present simulations of the effects of this missing information on the reconstruction of ideal objects.

description: 48. Hesperiidae – skippers Skippers are small to medium-sized insects that are distinguished from other butterflies by the combination of three pairs of legs that are all functional for walking and 12 wing veins unbranched from the base to the outer margin of the wing. Skippers are also characterized by having a stout, moth-like thorax and abdomen. Some species have a hook-like antenna tip. Most Hesperiidae larvae construct shelters in webbed or folded leaves; they feed on a variety of flowering plants. The Hesperiidae is currently divided into five subfamilies, but the higher relationships are not completely understood and some of these subfamilies are likely paraphyletic. More than 3 400 species are known worldwide, with the greatest diversity occurring in the tropics. Approximately 300 species are known from North America; 31 species are known from AB.

At leading order, the results confirm the Luttinger liquid and conformal field theory predictions.

description: We discuss a novel strategy for computing the eigenvalues and eigenfunctions of the relativistic Dirac operator with a radially symmetric potential. The virtues of this strategy lie on the fact that it avoids completely the phenomenon of spectral pollution and it always provides two-side estimates for the eigenvalues with explicit error bounds on both eigenvalues and eigenfunctions. We also discuss convergence rates of the method as well as illustrate our results with various numerical experiments.

description: The folding of biological macromolecules is a fundamental process of which we lack a full comprehension. Mostly studied in proteins and RNA, single-stranded DNA (ssDNA) also folds, at physiological salt conditions, by forming non-specific secondary structures that are difficult to characterize with biophysical techniques. Here we present a helix-coil model for secondary structure formation, where ssDNA bases are organized in two different types of domains (compact and free). The model contains two parameters: the energy gain per base in a compact domain, $ε$, and the cooperativity related to the interfacial energy between different domains, $γ$. We tested the ability of the model to quantify the formation of secondary structure in ssDNA molecules mechanically stretched with optical tweezers. The model reproduces the experimental force-extension curves in ssDNA of different molecular lengths and varying sodium and magnesium concentrations. Salt-correction effects for the energy of compact domains and the interfacial energy are found to be compatible with those of DNA hybridization. The model also predicts the folding free energy and the average size of domains at zero force, finding good agreement with secondary structure predictions by Mfold. We envision the model could be further extended to investigate native folding in RNA and proteins.

description: Schulentwicklung als Bemühungen, Schulen im Sinne erfolgreicher Qualitätsverbesserungen oder innovativen Wandels weiterzuentwickeln, damit sie die an sie gestellten Anforderungen des Bildungsauftrags möglichst optimal bewältigen können, hat sich zumeist als schwieriger und langwieriger erwiesen als es von Bildungsadministrationen, von der Wissenschaft oder von Schulen selbst erwartet wurde. Die Initiierung von Schulentwicklungsprozessen und die Implementation von Neuerungen haben vielfach nicht zu einer Institutionalisierung von Veränderungen der Alltagspraxis oder zu Qualitätsverbesserungen geführt. Dies liegt zum Teil zunächst an der besonderen Verfasstheit und Komplexität der Bildungsinstitution Schule (als Organisation von Expert*innen mit individuellem Autonomieanspruch) und an der Charakteristik und Komplexität der Innovationen selbst (Rogers, 2005), so dass Voraussetzungen für Veränderungen (z. B. Motivationen, Strukturen, Strategien) erst mühsam hergestellt werden müssen (Holtappels, 2014). [...] Direktlink zum Sammelband: 10.5281/zenodo.4498782 . Für Zitationen in diesem Abschnitt s.

Internally consistent thermodynamic data and phase relations in the CaO-Al₂O₃-SiO₂-H₂O system
Creators: name: Hammerstrom, Lyle Thomas
Publisher: name: University of British Columbia
Year: 2010

description: Internally consistent thermodynamic data for 23 phases in the CaO-Al₂O₃-SiO₂-H₂O system are determined by linear programming consistent set analysis. The consistent set analysis is based on published experimental petrology data for equilibrium reactions involving the phases in this system. Inconsistencies in the experimental data are removed by moving four data points beyond the maximum error allowed by the specific authors or by ignoring some portions of the questionable data. The phase relations among the phases between 0 to 2000°C and 0 to 50,000 bars are calculated using the consistent thermodynamic data with the computer program PT-SYSTEM written by T.H. Brown and E.H. Perkins of the Department of Geological Sciences at the University of British Columbia. The stable portions of the 236 stable equilibrium reactions are drawn on pressure-temperature (P-T) diagrams showing the phase relations of each phase. The P-T diagrams can be used to interpret the petrogenesis of metamorphic zones containing the phases. The consistent thermodynamic data in this study can be improved by undertaking petrology experiments which will substantiate and further define the data. Experiments investigating the stability of prehnite, wairakite and heulandite are recommended. Updating of the internally consistent thermodynamic properties for existing and new phases should be carried out for each additional set of experimental data by redoing the linear programming consistent set analysis on the entire experimental data set. The new thermodynamic properties for the phases could then be used to calculate the new phase relations.

Classical and Quantum Gravitational Collapse in d-dim AdS Spacetime II. Quantum States and Hawking Radiation

description: In a previous paper we studied the collapse of a spherically symmetric dust distribution (marginally bound LTB) in d-dimensional AdS spacetime and obtained the condition for the formation of trapped surfaces. Here we extend the analysis by giving the canonical theory for the same and subsequently quantize the system by solving the Wheeler-DeWitt equation. We show that for the case of small dust perturbations around a black hole the wave functionals so obtained describe an AdS-Schwarzschild black hole in equilibrium with a thermal bath at Hawking temperature and show the non-trivial dependence of this temperature on the number of spacetime dimensions and the cosmological constant.

A new equation of state for dense hydrogen-helium mixtures II: taking into account hydrogen-helium interactions

description: In a recent paper (Chabrier et al. 2019), we have derived a new equation of state (EOS) for dense hydrogen/helium mixtures which covers the temperature-density domain from solar-type stars to brown dwarfs and gaseous planets. This EOS is based on the so-called additive volume law and thus does not take into account the interactions between the hydrogen and helium species. In the present paper, we go beyond these calculations by taking into account H/He interactions, derived from quantum molecular dynamics simulations. These interactions, which eventually lead to H/He phase separation, become important at low temperature and high density, in the domain of brown dwarfs and giant planets. The tables of this new EOS are made publicly available.

description: We use the Stokes photon of a biphoton pair to set the time origin for electro-optic modulation of the wave function of the anti-Stokes photon thereby allowing arbitrary phase and amplitude modulation. We demonstrate conditional single-photon wave functions composed of several pulses, or instead, having gaussian or exponential shapes.
Superconductivity of hexagonal heavily-boron doped silicon carbide

description: In 2004 the discovery of superconductivity in heavily boron-doped diamond (C:B) led to an increasing interest in the superconducting phases of wide-gap semiconductors. Subsequently superconductivity was found in heavily boron-doped cubic silicon (Si:B) and recently in the stochiometric ''mixture'' of heavily boron-doped silicon carbide (SiC:B). The latter system surprisingly exhibits type-I superconductivity in contrast to the type-II superconductors C:B and Si:B. Here we will focus on the specific heat of two different superconducting samples of boron-doped SiC. One of them contains cubic and hexagonal SiC whereas the other consists mainly of hexagonal SiC without any detectable cubic phase fraction. The electronic specific heat in the superconducting state of both samples SiC:B can be described by either assuming a BCS-type exponentional temperature dependence or a power-law behavior.

description: Die Relevanz von gelingenden Transfer- und Implementationsprozessen für die erfolgreiche Umsetzung von Reformen sowohl auf System- als auch Schulebene gilt in der Schulentwicklungsdiskussion als unbestritten (vgl. van Holt, 2014; Gräsel, 2010; Jäger, 2004). So betont auch die KMK in ihrer jüngst überarbeiteten Gesamtstrategie zum Bildungsmonitoring: «Die Aufgabe der Landesinstitute und Qualitätseinrichtungen der Länder besteht in diesem Zusammenhang darin, Forschungswissen in Kooperation mit wissenschaftlichen Einrichtungen adressatengerecht für die Schulen, die Bildungsadministration und die Bildungspolitik aufzubereiten und zu verbreiten. Um nachhaltig Wirkung in der Fläche erzielen zu können, bedarf es ferner besonderer Implementations- und Transferstrategien in den Ländern» (KMK, 2015, S. 14). Damit werden Wissenschaft und Landesinstitute als zentrale Kooperationspartner benannt, die Wissen für Schulen und Administration aufbereiten und transferieren sollen. Unklar bleibt jedoch, wie solche Kooperationsstrukturen konkret zu denken sind und was «besondere» Implementations- und Transferstrategien für Schulen und Bildungsadministration kennzeichnet.

B-Meson Wave Function through A Comparative Analysis of the $B\to π$, $K$ Transition Form Factors

description: The properties of the B-meson light-cone wave function up to next-to-leading order Fock state expansion have been studied through a comparative study of the $B\to π$, $K$ transition form factors within the $k_T$ factorization approach and the light-cone sum rule analysis. The transition form factors $F^{B\toπ}_{+,0,T}$ and $F^{B\to K}_{+,0,T}$ are carefully re-calculated up to ${\cal O}(1/m_b^2)$ within the $k_T$ factorization approach in the large recoil region, in which the main theoretical uncertainties are discussed. The QCD light-cone sum rule is applicable in the large and intermediate energy regions, and the QCD light-cone sum rule results in Ref.\cite{sumrule} are adopted for such a comparative study. It is found that when the two phenomenological parameters $\barΛ\in [0.50,0.55]$ and $δ\in[0.25,0.30]$, the results of $F^{B\toπ}_{+,0,T}(Q^2)$ and $F^{B\to K}_{+,0,T}(Q^2)$ from these two approaches are consistent with each other in the large recoil energy region.

Initial-state randomness as a universal source of decoherence

description: We study time evolution of entanglement between two qubits, which are part of a larger system, after starting from a random initial product state. We show that, due to randomness in the initial product state, entanglement is present only between directly coupled qubits and only for short times. Time dependence of the entanglement appears essentially independent of the specific hamiltonian used for time evolution and is well reproduced by a parameter-free two-body random matrix model.

On non-vanishing of cohomologies of generalized Raynaud polarized surfaces

description: We consider a family of slightly extended version of the Raynaud's surfaces X over the field of positive characteristic with Mumford-Szpiro type polarizations Z, which have Kodaira non-vanishing H^1(X, Z^{-1})\ne 0. The surfaces are at least normal but smooth under a special condition. We compute the cohomologies H^i(X, Z^n), for intergers i and n, and study their (non-)vanishing. Finally, we give a fairly large family of non Mumford-Szpiro type polarizations Z_{a,b} with Kodaira non-vanishing.
description: Previous version has been largely revised. In particular, we consider the Mumford-Szpiro type polarization, which is more natural than the previous version. Also we introduce a class of non Mumford-Szpiro type polarizations causing Kodaira non-vanishing
