description: Transiting planets like HD209458b offer a unique opportunity to scrutinize their atmospheric composition and structure. Transit spectroscopy probes the transition region between the day and night sides, called limb. We present a re-analysis of existing archived HST/STIS transmission spectra of HD209458b's atmosphere. From these observations we: Identify H2 Rayleigh scattering, derive the absolute Sodium abundance and quantify its depletion in the upper atmosphere, extract a stratospheric T-P profile with a temperature inversion and explain broad band absorptions with the presence of TiO and VO molecules in the atmosphere of this planet.

description: ENJOI will build a Manifesto of Standards, Principles and Indicators (SPIs) for Outstanding Open Science Communication through many diverse lines of actions. Besides desk research and direct interviews and surveys, ENJOI will also organise Engagement Workshops and Labs to involve an extensive range of diverse stakeholders in the definition, assessment, evaluation, co-design, amendment and iterative improvement of its SPIs as well as of its guidelines, practices, tools and prototypes which are the basis of its core actions. The main objective of this working document is to develop and implement a methodology for continuous evaluation of the Engagement Workshops (EWs) and the Labs. These EWs and Labs will be held in Italy, Spain, Portugal and Belgium. The continuous evaluation falls under the so-called first strand of research of the ENJOI project. This working document details the steps towards the evaluation methodology. It is a working document to include insights from the cascade approach the project has embraced.

description: Kossovsky recently conjectured that the distribution of leading digits of a chain of probability distributions converges to Benford's law as the length of the chain grows. We prove his conjecture in many cases, and provide an interpretation in terms of products of independent random variables and a central limit theorem. An interesting consequence is that in hierarchical Bayesian models priors tend to satisfy Benford's Law as the number of levels of the hierarchy increases, which allows us to develop some simple tests (based on Benford's law) to test proposed models. We give explicit formulas for the error terms as sums of Mellin transforms, which converges extremely rapidly as the number of terms in the chain grows. We may interpret our results as showing that certain Markov chain Monte Carlo processes are rapidly mixing to Benford's law.

A thermodynamic analysis of several pressurized fluidized bed combined cycle power generation systems
Creators: name: Anastasiou, Roger
Publisher: name: University of British Columbia
Year: 2010

description: This thesis presents the results of computer modelling of two classes of combined cycle pressurized fluidized bed, coal fired power generation systems. The steam tube and air heater cycles have been proposed for future power stations because of their cost effectiveness and low pollution. The performance of the air heater cycle and seven variations of the steam tube cycle are simulated. The emphasis in modelling is to develop a system which will compare the cycles on an equal basis. Several configurations of the steam tube cycle are modelled using Hat Creek coal. Intercooling is found to be beneficial to the steam tube cycle, while recuperation is detrimental. The intercooled steam tube cycle is found to be 2 percentage points more efficient than conventional coal fired power plants. The air heater cycle has an efficiency similar to the conventional cycle. The part load simulation of a single module, air heater plant was also completed, indicating that when operating at 50% load, the gross thermal efficiency drops from 36.8% to 30.8%.

description: In order to study the X-ray properties of young stellar objects (YSOs), we analyze an exceptionally sensitive Chandra dataset of the Coronet cluster in the CrA star-forming region, achieving a limiting luminosity of LXmin=5E26 erg/sec for lightly absorbed sources. This dataset represents one of the most sensitive X-ray observations ever obtained of a star-forming region. The X-ray data are used to investigate the membership status of tentative members of the region, to derive plasma temperatures and X-ray luminosities of the YSOs, and to investigate variability on the timescale of several years. 46 of the 92 X-ray sources in the merged Chandra image can be identified with optical or near/mid-infrared counterparts. X-ray emission is detected from all of the previously known optically visible late-type (spectral types G to M) stellar cluster members, from five of the eight brown dwarf candidates, and from nine embedded objects ("protostars") with class 0, class I, or flat-spectrum SEDs in the field of view. While the Herbig Ae/Be stars TY CrA and R CrA, a close companion of the B9e star HD 176386, and the F0e star T CrA are detected, no X-ray emission is found from any of the Herbig-Haro (HH) objects or the protostellar cores without infrared source. We find indications for diffuse X-ray emission near R CrA / IRS 7. The observed X-ray properties of the Coronet YSOs are consistent with coronal activity; no soft spectral components hinting towards X-ray emission from accretion shocks were found. The X-ray emission of the AeBe stars TY CrA and HD 176386 originates probably from close late-type companions. The Ae star R Cra shows a peculiar X-ray spectrum and an extremely hot plasma temperature. Finally, we discuss the differences of the X-ray properties of YSOs in different evolutionary stages.

description: We study equivariant families of discrete Hamiltonians on amenable geometries and their integrated density of states (IDS). We prove that the eigenspace of a fixed energy is spanned by eigenfunctions with compact support. The size of a jump of the IDS is consequently given by the equivariant dimension of the subspace spanned by such eigenfunctions. From this we deduce uniform convergence (w.r.t. the spectral parameter) of the finite volume approximants of the IDS. Our framework includes quasiperiodic operators on Delone sets, periodic and random operators on quasi-transitive graphs, and operators on percolation graphs.

Jhs. n. Chr. Vergleichbare Stücke stammen aus dem gesamten Mittelmeergebiet, besonders aber aus dem adriatischen Raum. Durch den Fund der beiden Fragmente in Shkodra kann nicht nur ein weiterer Punkt auf der Verbreitungskarte der ›korinthischen‹ Keramik hinzugefügt werden, die Stücke erweitern zugleich auch unsere Kenntnisse hinsichtlich Ikonographie und Formenvielfalt dieser Keramikgattung. So wird vorgeschlagen, der offenen Systematik von Malfitana 2007 zwei neue Hirtenszenen (bei Gruppe III oder V) und eine neue ikonografische Gruppe hinzuzufügen: die Gruppe VIII: ›Tierfriese‹. Die beiden ›korinthischen‹ Reliefgefäße aus Shkodra verdeutlichen erneut den engen Zusammenhang zwischen literarischer Überlieferung und bildender Kunst. Durch ihre singuläre Stellung in Bezug auf Form und Größe und die bislang unbekannten Bildmotiven zeigen sie, wie groß das Potential ist, das diese Gattung nach wie vor für die Forschung zu bieten hat.

description: Recent neutrino oscillation experiments used high atomic number nuclear targets to attain sufficient interaction rates. The use of these complex targets introduced systematic uncertainties due to the nuclear effects in the experimental observables and need to be measured properly to pin down the discovery. Through this simulation work, we are trying to quantify the nuclear effects in the argon (Ar) target in comparison to hydrogen (H) target which are proposed to be used at Deep Underground Neutrino Experiment far detector and near detector, respectively. Generates Events for Neutrino Interaction Experiments and NuWro, two neutrino event generators, are used to construct final state kinematics. To quantify the systematic uncertainties in the observables, we present the ratio of the oscillation probability (P(Ar)/P(H)) as a function of reconstructed neutrino energy.

description: We use entangled multimode coherent states to produce entangled giant graviton states, in the context of gauge/gravity duality. We make a smeared distribution of the entangled multimode coherent states on the circle, or on the five-sphere, in the higher dimensional view. In gauge/gravity duality, we analyze the superposition of giant graviton states, and the entangled pairs of giant graviton states. We map a class of angular distribution functions to unitary operations on the pairs. We also use Young tableau states to construct cat states and qudit states. Various bipartite quantum states involving Young tableau states are analyzed, including micro-macro entangled states. Mixed states of Young tableau states are generated, by using ensemble mixing using angular distribution functions, and also by going through noisy quantum channels. We then produce mixed entangled pair of giant graviton states, by including interaction with the environment and using noisy quantum channels.

New phase space structures  in the Gaia data:  a dynamically young disk
Creators: name: Antoja, Teresa
Publisher: name: Zenodo
Year: 2019

description: We will present the new phase space substructures sampled by the six million stars’ dataset with 6D phase-space information from the Gaia satellite, thanks to the large amount of data and their excellent precision. The new morphologies discovered are a snail-shaped structure in the combination of vertical position and velocity, and diagonal ridges in the azimuthal velocity combined with galactic radius. The vertical structures are signatures of ongoing phase-mixing and our hypothesis is that the Milky Way disk might have been perturbed in the past. This helps us to determine properties of the possible perturbation and parameters of the Milky Way potential as well. By considering a realistic model for the potential of the Galaxy and the associated orbital vertical frequencies, we infer that a perturbation might have occurred between 300 and 900 million years ago, which is consistent with estimates of the previous pericenter of the Sagittarius dwarf galaxy. But we will also review alternative hypothesis presented so far such as the effects of the buckling of the bar or bending waves in the disk. The in-plane diagonal ridges might be a result of phase-mixing or/and resonant effects of the bar and spiral arms. In any case, the Gaia data prove that the disk of our Galaxy strongly changes with time and is very responsive to perturbations.
The prediction of short term adjustment in psychotic patients
Creators: name: Smith, Geoffrey Norman
Publisher: name: University of British Columbia
Year: 2010

description: Progress in schizophrenia research has been hindered by the limitations of contemporary diagnostic criteria. All widely used diagnostic systems allow considerable variability in symptoms between schizophrenics and much similarity across psychotic disorders. Furthermore, schizophrenics show large differences in response to treatment strategies and in prognosis. These facts have led to a growing consensus that schizophrenia is not a homogeneous disorder but represents a heterogeneous collection of disorders. In the face of this heterogeneity, most schizophrenia research is conducted by comparing a group of diagnosed schizophrenics with a control group. This approach carries with it the implicit assumption that the disorder is homogeneous. The variability between schizophrenics and similarities across various psychotic disorders in association with this research strategy probably contributes to the slow progress in schizophrenia research. An alternative, three-point research strategy was proposed: 1) All psychotic patients, without diagnosed organic disorders, should be included in research studies to compensate for the imprecision in contemporary diagnostic procedures, 2) multiple measures should be used to identify variables that cluster within subgroups of patients, and 3) any identified subcategory of schizophrenia should be evaluated with regard to how well it predicts response to treatment and prognosis. In the present study, premorbid adjustment, negative symptoms (e.g., flat affect), and smooth pursuit eye movement anomalies were used to predict rehospitalization, general level of adjustment at follow-up, and employment-heterosexual period was nine to 18 months. Thirty-seven patients who had recently experienced their first psychotic episode served as subjects. Twenty were diagnosed schizophreniform, nine unipolar depressed, six bipolar, and two paranoid. The results of this study were successful in identifying two subgroups of psychotic patients. Disrupted eye-tracking, poor premorbid adjustment and a preponderance of negative symptoms tended to cluster in individuals with poor general and employment-heterosexual adjustment while good eye-tracking, normal premorbid adjustment, and a relative absence of negative symptoms were common in individuals with good adjustment at follow-up. Rehospitalization was not predicted successfully. The results are discussed in terms of their implications for a neuropathological subtype of schizophrenia. Suggestions for further research to extend the present findings are offered.
Bound states in N = 4 SYM on T^3: Spin(2n) and the exceptional groups

description: The low energy spectrum of (3+1)-dimensional N=4 supersymmetric Yang-Mills theory on a spatial three-torus contains a certain number of bound states, characterized by their discrete abelian magnetic and electric 't Hooft fluxes. At weak coupling, the wave-functions of these states are supported near points in the moduli space of flat connections where the unbroken gauge group is semi-simple. The number of such states is related to the number of normalizable bound states at threshold in the supersymmetric matrix quantum mechanics with 16 supercharges based on this unbroken group. Mathematically, the determination of the spectrum relies on the classification of almost commuting triples with semi-simple centralizers. We complete the work begun in a previous paper, by computing the spectrum of bound states in theories based on the even-dimensional spin groups and the exceptional groups. The results satisfy the constraints of S-duality in a rather non-trivial way.

description: Extensive literature exists on how to test for normality, especially for identically and independently distributed (i.i.d) processes. The case of dependent samples has also been addressed, but only for scalar random processes. For this reason, we have proposed a joint normality test for multivariate time-series, extending Mardia's Kurtosis test. In the continuity of this work, we provide here an original performance study of the latter test applied to two-dimensional projections. By leveraging copula, we conduct a comparative study between the bivariate tests and their scalar counterparts. This simulation study reveals that one-dimensional random projections lead to notably less powerful tests than two-dimensional ones.
A design for the evaluation of neighbourhood design guidelines
Creators: name: Goldburn, Christine Mary
Publisher: name: University of British Columbia
Year: 2010

description: In 1982, after considerable discussion and negotiation, the City of Edmonton municipal council approved a neighbourhood plan which had as one of its components a set of Design Guidelines intended to mitigate the perceived negative effects of the high density residential environment which the plan proposed. As well, the developers' concept for the area promoted the creation of a highly interactive and cohesive community, free of crime and with a strong sense of identity as promoted in Oscar Newman's book Defensible Space. As yet the neighbourhood has not been built, but once the area is developed and occupied, it is expected that the City Administration will conduct an evaluation of the Neighbourhood to determine whether the design concept as expressed in the Guidelines was effective, and effected, in the manner initially proposed. This thesis will undertake the initial stages of this evaluation, by examining the theory of neighbourhoods and neighbouring as well as the past experience of other cities with respect to neighbourhood development. This part of the thesis takes the form of extensive literature review, and results in the identification of four major and several minor topics which should be examined in the eventual evaluation of Terra Losa. The thesis then identifies the implicit and explicit goals of the Design Guidelines. In a discussion based on the results of the literature review, the relevance and feasibility of the goals is examined. Finally, and again based on the literature, particularly the case studies, an evaluation of the Defensible Space concept is presented and suggestions are made as to the procedures to be followed in eventually conducting a neighbourhood evaluation. The thesis concludes that although the intentions of the developers' concept is laudable, that the effectiveness of physical design in creation of a strong social community is limited, though it appears from past experience that the Guidelines, if properly implemented, would be effective in achieving this limited level of influence and relatively high levels of residential satisfaction.

description: Consistent coupling of effective field theories with a quantum theory of gravity appears to require bounds on the the rank of the gauge group and the amount of matter. We consider landscapes of field theories subject to such to boundedness constraints. We argue that appropriately "coarse-grained" aspects of the randomly chosen field theory in such landscapes, such as the fraction of gauge groups with ranks in a given range, can be statistically predictable. To illustrate our point we show how the uniform measures on simple classes of N=1 quiver gauge theories localize in the vicinity of theories with certain typical structures. Generically, this approach would predict a high energy theory with very many gauge factors, with the high rank factors largely decoupled from the low rank factors if we require asymptotic freedom for the latter.

Intracluster Short Gamma-Ray Bursts by Compact Binary Mergers

Year: 2007

description: One of the possible origins of short gamma-ray bursts (SGRBs) is merging of compact binaries, and the effect of large kick velocity is a signature that can be used as an observational test for this hypothesis. Intracluster SGRBs that escaped from a host galaxy in a galaxy cluster are interesting in this context, since they would escape more easily by cluster tidal force, and would have brighter afterglow luminosity by dense intracluster gas, than those in general field galaxies. Here we calculate the escape fraction of compact binaries from their host galaxies in a galaxy cluster, and discuss some observational implications. We found that the escape fraction strongly depends on the nature of dark matter subhalos associated with member galaxies. If the amount of dark matter around member galaxies is not large and the gravitational potential for an escaping binary is determined mostly by stellar mass, most of SGRBs should escape and be observed as hostless, which is a much higher fraction than those in the field. Hence, statistics of intracluster SGRBs could give important information about the dark matter distribution in galaxy clusters, as well as hints for the origin of SGRBs.

description: In most of the studies concerning nonlinear wave equations of Korteweg-de Vries type, the authors focus on waves of elevation. Such waves have general form ~$u_{\text{u}}(x,t)=A f(x-vt)$, where ~$A>0$. In this communication we show that if ~$u_{\text{up}}(x,t)=A f(x-vt)$ is the solution of a given nonlinear equation, then $u_{\text{down}}(x,t)=-A f(x-vt)$, that is, an inverted wave is the solution of the same equation, but with changed sign of the parameter ~$α$. This property is common for KdV, extended KdV, fifth-order KdV, Gardner equations, and generalizations for cases with an uneven bottom.

Nonetheless, it was effectively published (see Art. 31.1, ICN) only on May 8th 1890 (Stafleu & Cowan 1983). Petersen (1890) only cited a Warming gathering, without further details. Three specimens were found at C herbarium with labels indicating they were part of Warming’s Herbarium, together with the collector’s handwriting, gathering number and locality. A photo negative made by Macbride (Photo Negative no. F 9838) representing the specimen once placed at B herbarium, which was subsequently destroyed, was also found with fragments and an illustrative analysis. The specimen C 10014449 is designated here as lectotype since it is the most complete extant duplicate.

description: A clay ball with a Cypro-Minoan inscription excavated in a LH IIIC Developed workshop context at the northern tip of Tiryns’ Lower Citadel forms the basis for this discussion on interaction patterns and contacts between Mycenaean Tiryns and Late Bronze Age Cyprus. To provide a background to the contextual assessment of the Tiryns clay ball documents, contexts and practices associated with the Cypro-Minoan script/s on Cyprus are discussed. The analysis of the Tiryns clay ball focuses on epigraphy, find context and the dating of the object. While it is impossible to establish the provenance of the clay ball on the basis of current evidence, stratigraphic details and its find spot within a workshop area point to a post-palatial date. An overview of East Mediterranean (especially Cypriot) objects found in Tiryns identifies a few areas where such artefacts occur more frequently and discusses implications of ›Cypriot‹ practices on the basis of contextual data. Intimate contacts between Tiryns and Cyprus are attested to during the late palatial period, but continue into the postpalatial period and point to interpersonal contacts rather than merely long-distance trade.

Protologue citation:—“ Brasilien: Ohne bestimmten Standort, wahrscheinlich Matto Grosso (Burchell n. 8351).”
Notes:— Schumann (1902) cited only the gathering Burchell 8351, without specifying a herbarium. Six specimens and a photograph of Macbride’s Collection (Photo Negative no. F 9837) were found with labels correctly indicating collector and gathering number. The specimen placed at B herbarium, subsequently destroyed, was certainly analyzed by Schumann, since it bears a label of revision with the author’s signature. Among them, we chose to designate specimen K 000586892 here as the lectotype since it also has the author´s annotation, indicating it as a new species.

Effects of a Velocity Shear on Double Current Sheet Systems: Explosive Reconnection and Particle Acceleration

description: The effect of a parallel velocity shear on the explosive phase of a double current sheet system is investigated within the 2D resistive magnetohydrodynamic (MHD) framework. We further explore the effect of this shear on acceleration of test particles. The general evolution pattern of the double current sheets is similar for all sub-Alfvénic shears with respect to the initial transient phase, the onset of the plasmoid instability and the final relaxation phase. We find that the theoretical scaling of the reconnection rate with shear holds if the rate is measured when the islands have a similar size. The larger island widths for lower shears greatly enhance the reconnection rate during the explosive phase. We have further examined the modification of the energy spectrum of the accelerated particles in the presence of a shear. Our results also show that the flow only modifies the high energy tail of the particle spectrum and has negligible effect on the power-law index. Individual particle trajectories help to explore the various mechanisms associated with the acceleration. Based on the location of the particles, the acceleration mechanisms are found to vary. We highlight the importance of the convective electric field in the inflow as well as the outflow region inside large magnetic islands in the acceleration of particles. The interaction and reflection of the particles with the reconnection exhausts inside the large scale primary magnetic islands is found to have a significant effect on the energization of the particles.

description: The stellar initial mass function (IMF) is central to our interpretation of astronomical observables and to our understanding of most baryonic processes within galaxies. The universality of the IMF, suggested by observations in our own Milky Way, has been thoroughly revisited due to the apparent excess of low-mass stars in the central regions of massive quiescent galaxies. As part of the efforts within the Fornax 3D project, we aim to characterize the two-dimensional IMF variations in a sample of 23 quiescent galaxies within the Fornax cluster. For each galaxy in the sample, we measured the mean age, metallicity, [Mg/Fe], and IMF slope maps from spatially resolved integrated spectra. The IMF maps show a variety of behaviors and internal substructures, roughly following metallicity variations. However, metallicity alone is not able to fully explain the complexity exhibited by the IMF maps. In particular, for relatively metal-poor stellar populations, the slope of the IMF seems to depend on the (specific) star formation rate at which stars were formed. Moreover, metallicity maps have systematically higher ellipticities than IMF slope ones. At the same time, both metallicity and IMF slope maps have at the same time higher ellipticities than the stellar light distribution in our sample of galaxies. In addition we find that, regardless of the stellar mass, every galaxy in our sample shows a positive radial [Mg/Fe] gradient. This results in a strong [Fe/H]-[Mg/Fe] relation, similar to what is observed in nearby, resolved galaxies. Since the formation history and chemical enrichment of galaxies are causally driven by changes in the IMF, our findings call for a physically motivated interpretation of stellar population measurements based on integrated spectra that take into account any possible time evolution of the stellar populations.

description: We consider several new classes of viable vector field alternatives to the inflaton and quintessence scalar fields. Spatial vector fields are shown to be compatible with the cosmological anisotropy bounds if only slightly displaced from the potential minimum while dominant, or if driving an anisotropic expansion with nearly vanishing quadropole today. The Bianchi I model with a spatial field and an isotropic fluid is studied as a dynamical system, and several types of scaling solutions are found. On the other hand, time-like fields are automatically compatible with large-scale isotropy. We show that they can be dynamically important if non-minimal gravity couplings are taken into account. As an example, we reconstruct a vector-Gauss-Bonnet model which generates the concordance model acceleration at late times and supports an inflationary epoch at high curvatures. The evolution of vortical perturbations is considered.

Notes:— Körnicke (1862) cited gatherings from Sellow (B), Riedel (“ Breideb ” on protologue) (LE), and Schott (W). Three specimens of Sellow are at BM and K herbaria, but all are duplicates of the specimen destroyed, once placed at B herbarium. The same is true for the Schott collection, which was originally housed at W and posteriorly destroyed. Nonetheless, a duplicate remains at BM herbarium. The Riedel 871 gathering is at LE herbarium, and duplicates can be found at P and S. We designate here the specimen LE 01041379 (Riedel 871) as the lectotype since it is the only one still housed at the original herbarium cited in the protologue.
