description: At higher education institutions (HEI), which for centuries served only to educate the elite, the composition of the student body is increasingly changing towards greater social and cultural diversity. Students’ differences are also the focus of this article, but not with a specific emphasis on preselected categories. Instead, the article asks how students in teaching in higher education (HE) are represented in the print media and professional discourse in Germany, i.e., which categories of difference are constructed as relevant in HE teaching contexts, which are normalized and (de)legitimized, and what is expected of HEI concerning these differences. Second, to what extent does this change over time, particularly concerning the new circumstances of Corona‐based digital teaching in 2020? The contribution is based on a combination of discourse theory and neo‐institutional organizational sociology. Discourses are a place where social expectations towards organizations are negotiated and constructed. Simultaneously, the discourses construct a specific understanding of HE, making visible openings and closures concerning different groups of students. Which students are constructed as legitimate, desirable, at risk of dropping out, or a risk for HE quality? Based on qualitative content analysis, the article shows that it is less the traditional socio‐structural categories such as gender, social or ethnic origin, or impairments, that are discussed to be relevant in HE teaching contexts. The reproduction of inequality and the associated discrimination is hardly discussed. The focus is instead on the students’ differences concerning individualizable characteristics, competencies, or study practices. Even though many of these individualized differences are conveyed via socio‐structural categories, this connection is often not considered in the discourses.

description: We report an unexpected mechanism by which an epitaxial interface can form between materials having strongly mismatched lattice constants. A simple model is proposed in which one material tilts out of the interface plane to create a coincidence-site lattice that balances two competing geometrical criteria---low residual strain and short coincidence-lattice period. We apply this model, along with complementary first-principles total-energy calculations, to the interface formed by molecular-beam epitaxy of cubic Fe on hexagonal GaN and find excellent agreement between theory and experiment.

A longitudinal comparison of the metabolic characteristics of outpatients with first episode psychosis taking second generation antipsychotics : an interim analysis
Creators: name: Whitney, Zachary
Publisher: name: University of British Columbia
Year: 2016

description: Background. Second generation antipsychotics (SGAs) are used widely for the treatment of schizophrenia and other psychotic disorders. Despite the efficacy of these compounds, they have been associated with a number of adverse events such as weight gain and type II diabetes. Methods. In this study we have performed an interim analysis of a four-month long clinical trial to evaluate the effects of SGA drugs on weight gain in patients with first episode psychosis. A completer’s analysis was performed approximately mid-way through the trial. Anthropometric measures were collected at baseline and again at four months. Physical activity and eating patterns were measured through the international physical activity questionnaire (IPAQ) and three factor eating questionnaire (TFEQ). Secondary outcomes that were investigated include the effects on psychopathology using the positive and negative syndromes scale (PANSS) and the Calgary depression scale (CDS), effects on global functioning through the social and occupational functioning scale (SOFAS), quality of life as assessed by the short-form 36 (SF-36). Adherence to medication was assessed through the medication adherence rating scale (MARS). A simple t-test (p=<.05) was used to detect differences in anthropometric data, the PANSS, and the CDS. Repeated measures one-way analysis of variance (ANOVA) (p=<.05) was utilized for analysis of SF-36, TFEQ, IPAQ, and MARS. Findings. At baseline, patients taking antipsychotics weighed significantly more than the control group. Significant increases in waist circumference were observed in patients taking antipsychotics at four months. Significant differences in BMI and heart rate were detected between groups at four months. Significantly lower SF-36 summary scores were detected between groups with significant improvements in mental health summary scores in the antipsychotic group. CDS scores also improved significantly. Conclusion. At four months of treatment with SGAs, patients may show measurable changes in metabolic parameters that could eventually lead to metabolic syndrome.

description: Wie Selbststeuerung ein zentrales Element des Cooperativen Offenen Lernens (COOL) wurde. Das Cooperative Offene Lernen ist eine Lehrer*inneninitiative für mehr Selbstständigkeit, Eigenverantwortung und Kooperation im Bildungswesen. Auf die Schule bezogen handelt es sich um einen reformpädagogisch inspirierten Ansatz, der sich stark auf Unterrichts- beziehungsweise Schulentwicklung und selbstgesteuertes Lernen aller Akteure fokussiert. Dass Selbststeuerung viel mehr ist als eine Frage von Methoden und Formen des Offenen Lernens, war von vornherein klar. Dass diese „Haltung“, um die es letztlich geht, auch bei Lehrer*innen nicht vorausgesetzt werden kann, sondern unter anderem in speziellen Fortbildungsformaten gelernt werden muss und kann, war und ist eine zentrale Erkenntnis der COOL-Entwickler*innen. Dieser Beitrag beschreibt die Geschichte und Entwicklung von COOL sowie die Leistung von Franz Hofmann, der durch seine kritische Analyse, seine wissenschaftlich fundierten Beiträge und seine konkreten Angebote einen wesentlichen Anteil an der Weiterentwicklung dieses Unterrichts und Schulentwicklungsansatzes hatte.
description: How self-determination became a focus of COOL. Co-operative Open Learning is an initiative of (Austrian) teachers aiming at the promotion of self-determination strategies in the system of education. Concerning schools it is a concept based on reformpedagogy (Dalton-plan) focusing on the quality of teaching and school development. Selfdetermination has always been more than methods and tools of open learning. It is the professional attitude that makes the difference and this cannot be taken for granted with teachers. The COOL-development team has been aware that this attitude must be developed in special on-the-job training courses. This article describes the history and development of COOL and the helpful role of Franz Hofmann, who promoted and stimulated this school development concept with his critical analysis, theoretical contributions and practical support.

description: We develop a systematic approach to deriving addition theorems for, and some other bilocal sums of, spin spherical harmonics. In this first part we establish some necessary technical results. We discuss the factorization of orbital and spin degrees of freedom in certain products of Clebsch-Gordan coefficients, and obtain general explicit results for the matrix elements in configuration space of tensor products of arbitrary rank of the position and angular-momentum operators. These results are the basis of the addition theorems for spin spherical harmonics obtained in part II.

description: Malaria, a parasitic infection transmitted through the bites of female Anopheles mosquitoes carrying Plasmodium species, remains a significant global health challenge, particularly in sub-Saharan Africa where it accounts for the majority of malaria-related deaths. While Plasmodium falciparum is the predominant cause of malaria in this region, Plasmodium vivax prevails in other parts of the world such as Central and South America, North Africa, and the Middle East. The prevalence of malaria is influenced by various factors including altitude, age, and topography, with tropical regions characterized by high rainfall and colder climates posing a greater risk of parasitic infection.  The life cycle of the Anopheles mosquito comprises four stages: eggs, larvae, pupa, and adult (imago), with transmission occurring during the adult stage when the mosquito takes blood meals from humans. Climate conditions, including temperature and rainfall patterns, significantly impact the transmission dynamics of malaria. Certain population groups, such as pregnant women, children under five years old, immunocompromised individuals, and unexposed immigrants, are particularly vulnerable to malaria.  Fortunately, malaria is both preventable and treatable through a combination of interventions including intermittent preventive treatment, vaccination, insecticide-treated nets and sprays, and antimalarial drugs. However, achieving effective malaria control requires a multifaceted approach that addresses both prevention and treatment strategies.  This abstract provides insights into the epidemiology, transmission dynamics, and control measures of malaria, emphasizing the importance of targeted interventions to mitigate the burden of this disease on vulnerable populations

description: We report on a search for new particles in the diphoton channel using a data sample of $p\bar p$ collisions at $\sqrt{s} = 1.96$ TeV collected by the CDF II detector at the Fermilab Tevatron, with an integrated luminosity of 5.4 fb$^{-1}$. The diphoton invariant mass spectrum of the data agrees well with the standard model expectation. We set upper limits on the production cross section times branching ratio for the Randall-Sundrum graviton, as a function of diphoton mass. We subsequently derive lower limits on the graviton mass of 459 GeV$/c^{2}$ and 963 GeV$/c^{2}$, at the 95% confidence level, for coupling parameters ($k/\bar{M}_{Pl}$) of 0.01 and 0.1 respectively.

description: The Fisher-Rao distance is the geodesic distance between probability distributions in a statistical manifold equipped with the Fisher metric, which is a natural choice of Riemannian metric on such manifolds. It has recently been applied to supervised and unsupervised problems in machine learning, in various contexts. Finding closed-form expressions for the Fisher-Rao distance is generally a non-trivial task, and those are only available for a few families of probability distributions. In this survey, we collect examples of closed-form expressions for the Fisher-Rao distance of both discrete and continuous distributions, aiming to present them in a unified and accessible language. In doing so, we also: illustrate the relation between negative multinomial distributions and the hyperbolic model, include a few new examples, and write a few more in the standard form of elliptical distributions.

Year: 1975

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: Based on the results of part I, we obtain the general form of the addition theorem for spin spherical harmonics and give explicit results in the cases involving one spin-$s'$ and one spin-$s$ spherical harmonics with $s',s=1/2$, 1, 3/2, and $|s'-s|=0$, 1. We obtain also a fully general addition theorem for one scalar and one tensor spherical harmonic of arbitrary rank. A variety of bilocal sums of ordinary and spin spherical harmonics are given in explicit form, including a general explicit expression for bilocal spherical harmonics.
The role of Adamts9 in melanoblast migration and modification of the skin proteome
Creators: name: Tharmarajah, Grace T.
Publisher: name: University of British Columbia
Year: 2015

description: The glabrous skin, which includes, the tail, the footpads, the nose and the ears, of the mouse retain melanocytes in the dermis, the hair follicles of the epidermis and the interfollicular regions of the epidermis. Given that melanocytes in humans are exclusively found in the epidermis and hair follicles, the epidermis of the glabrous skin of the mouse can be a functional model in the study of melanocytes. A dominant N-ethyl-N-nitrosourea (ENU) mutagenesis screen of C3HeB/FeJ mice at the National Research Center for Environment and Health (GSF) in Germany recovered two mutants, Und3 and Und4. These mice are characterized by a reduction in pigmentation that is localized to the middle regions of the tail, with the base and tip retaining pigmentation. Mapping and sequencing revealed single base pair changes in Adamts9. The mutations in Adamts9 create null alleles and Adamts9, expressed in the epidermis, is required for melanoblast migration in the tail at 18.5 dpc. A conditional knockout of Adamts9 suggests that the hypopigmentation is due to the loss of Adamts9 in melanocytes, but not keratinocytes. Terminal amine isotopic labeling of substrates (TAILS) was used to identify changes in potential cleavage processes between Adamts9Und4/+ and wildtype mice. Several candidates, associated with the stratum basale, were found to be significantly different between the wildtype and the mutant proteomes. These candidates are involved in the regulation of cytoplasmic cell structure (Filamin-A, Filamin-B, beta-tubulin 4A and alpha-tubulin 1C), maintaining the structural organization of cells within the extracellular matrix (Plectin, Desmoplakin, Perisotin and Vimentin) and communication between cells (Type XII collagen, Type VII collagen, Fibrillin-1, Fibronectin, Tenascin and Biglycan). These findings suggest that Adamts9 is essential for the appropriate migration of melanoblasts in the developing embryo and immediately after birth. Additionally, this protease is likely involved in mouse pigmentation by maintaining an environment in the stratum basale that supports the migration of melanoblasts in the epidermis through the activation of proliferation pathways during development.

description: We report new near-IR integral field spectroscopy of the central starburst region of the barred spiral galaxy M83 obtained with CIRPASS on Gemini-S, which we analyse in conjunction with GHaFaS Fabry-Perot data, an AAT IRIS2 Ks-band image, and near- and mid-IR imaging from the Hubble and Spitzer space telescopes. The bulk of the current star formation activity is hidden from optical view by dust extinction, but is seen in the near- and mid-IR to the north of the nucleus. This region is being fed by inflow of gas through the bar of M83, traced by the prominent dust lane entering into the circumnuclear region from the north. An analysis of stellar ages confirms that the youngest stars are indeed in the northwest. A gradual age gradient, with older stars further to the south, characterises the well-known star-forming arc in the central region of M83. Detailed analyses of the Pa beta ionised gas kinematics and near-IR imaging confirm that the kinematic centre coincides with the photometric centre of M83, and that these are offset significantly, by about 3 arcsec or 60 pc, from the visible nucleus of the galaxy. We discuss two possible options, the first of which postulates that the kinematic and photometric centre traces a galaxy nucleus hidden by a substantial amount of dust extinction, in the range A_V=3-10 mag. By combining this information with kinematic results and using arguments from the literature, we conclude that such a scenario is, however, unlikely, as is the existence of other "hidden" nuclei in M83. We thus concur with recent authors and favour a second option, in which the nucleus of the galaxy is offset from its kinematic and photometric centre. This is presumably a result of some past interaction, possibly related to the event which lies at the origin of the disturbance of the outer disk of the galaxy. (Abridged)

description: The Common Muon Proton Apparatus for Structure and Spectroscopy (COMPASS) at CERN with its use of beams of naturally polarized muons scattered of a polarized deuteron target, provides an environment of hard scattering between quasi-real photons and partons. Hard hadron quasi-real photo-production with polarized initial states is sensitive to the polarized gluon distribution $Δ$G through $γ$-gluon($g$) direct channels as well as $q$-$g$ resolved processes. Comparisons of unpolarized differential cross section measurements to next-to-leading order (NLO) pQCD calculations are essential to develop our understanding of proton-proton and lepton-nucleon scattering at varying center of mass energies. These measurements are important to asses the applicability of NLO pQCD in interpreting polarized processes. In this talk we will discuss unidentified charged separated hadron production at low $Q^{2}$ (Q$^{2}<0.1 GeV^{2}/c^{2}$) and high transverse momenta (p$_{T}>1.0\,GeV/c$). $$ spectra of charged hadrons at $Q^{2}>1 GeV^{2}/c^{2}$ will also be discussed.

Molecular evolutionary analysis of TALE homeobox in Viridiplantae
Creators: name: Wang, Ming Hsiu
Publisher: name: University of British Columbia
Year: 2015

description: The emergence of embryophytes from their charophyte-like ancestor is estimated to have occurred 476-432 MYA. During the adaptation to land, embryophytes evolved to have sporic meiosis; whereas charophyte algae undergo zygotic meiosis. The transition to land required the embryophytes to develop specialized tissues and a cuticle to survive drier terrestrial environments. This transition resulted in increasing elaboration of the body plan in the diploid phase, establishing the sporophyte. It is hypothesized that diversification of heterodimeric TALE homeobox genes in the ancestral charophyte algae may have acted as new types of master regulators to control diploid-specific developmental program, which initiated the development of novel sporophytic body plan. This study is focused on determining TALE homeobox genealogy by comparing genetic sequences and gene structure of TALE homeobox found in the transcriptomes of Picocystis salinarum (prasinophyte), Mougeotia sp. (charophyte). and Cosmocladium constrictum (charophyte). The interaction of TALE homeobox proteins from Picocystis salinarum was tested with a Y2H assay. Prior to this study, it was known that the diploid developmental program was regulated by KNOX and BELL classes of TALE homeobox genes in embryophytes and KNOX and GSP1 classes of TALE homeobox genes in Chlamydomonas reinhardtii (chlorophyte). Through phylogenetic analysis, I found that charophytes express KNOX, BELL and GSP1 classes, and P. salinarum expresses KNOX, GSP1, divergent TALE, and two red algal homologs of the TALE homeobox. Furthermore, comparison of intron location indicated that the BELL and GSP1 genes in the charophytes may be homologous. Intron comparisons and phylogenetic analysis of the KNOX genes indicate that KNOX II class from streptophyta and KNOX from chlorophyta share the greatest similarity, whereas KNOX I class can be hypothesized to have emerged by gene duplication in the early charophyte ancestor. The Y2H assay of TALE homeobox from Picocystis salinarum shows that GSP1 and KNOX can interact, whereas the possibility of an interaction with the red algal homolog is inconclusive.

As a first application of this method, we use the binary black hole mergers observed during the LIGO, Virgo, and KAGRA third observation run to test the spatial distribution of these sources. We find no evidence for anisotropy in their angular distribution. We discuss further applications of this method to investigate other gravitational-wave source populations and their correlations to the cosmological large-scale structure.

Im Zentrum stehen gefährdete, „schwierige“ und scheiternde Bildungsbiografien in der Oberstufe, die mit quantitativen und qualitativen Methoden im Längsschnitt untersucht wurden. Die Ergebnisse sind vielfältig und deuten in ihrer Gesamtheit vor allem darauf hin, dass Rückstufungen und Abbrüche in der Oberstufe in nahezu allen Fällen auf eine Kombination schulischer und außerschulischer Ursachen zurückzuführen sind. Im Fazit ziehen wir erste Schlussfolgerungen für die Gestaltung von Beratung in der Oberstufe und geben einen Ausblick auf die Nutzung der Ergebnisse in einem zukünftigen Transferprojekt.

description: In 1979, for each signature for Fuchsian groups of the first kind, Bowen and Series constructed an explicit fundamental domain for one group of the signature, and from this a function on $\mathbb S^1$ tightly associated with this group. In general, their fundamental domain enjoys what has since been called the `extension property'. We determine the exact set of signatures for cocompact triangle groups for which this extension property can hold for any convex fundamental domain, and verify that for this restricted set, the Bowen-Series fundamental domain does have the property.
 To each Bowen-Series function in this corrected setting, we naturally associate four continuous deformation families of circle functions. We show that each of these functions is aperiodic if and only if it is surjective; and, is finite Markov if and only if its natural parameter is a hyperbolic fixed point of the triangle group at hand.

description: Employing an ensemble Monte Carlo transport simulation, we self-consistently analyze the spectral gain for different THz quantum cascade laser structures, considering bound-to-continuum as well as resonant phonon depopulation designs. In this context, we investigate temperature dependent gain broadening, affecting the temperature performance of THz structures. Furthermore, we discuss the influence of the individual scattering mechanisms, such as electron-electron, impurity and interface roughness scattering. A comparison of the simulation results to experimental data yields good agreement.

We have implemented this approach in the SACHS system to provide a semantic help system for spreadsheets applications. In this paper, we evaluate the (comprehension) coverage of SACHS on an Excel-based financial controlling system via a "Wizard-of-Oz" experiment. This shows that SACHS adds significant value, but systematically misses important classes of explanations. For judgements about the information contained in spreadsheets, we provide a first approach for an "assessment module" in SACHS.

Feasibility study of inductive heating coil with distributed resonant capacitors
Creators: name: Xu, Tingting
Publisher: name: University of British Columbia
Year: 2015

description: Steam Assisted Gravity Drainage (SAGD) method is one of the most common methods used in the process of heavy oil recovery. However, the method is economically inefficient, inherently dependent of water availability and has some detrimental impact on the environment. Therefore the need for an efficient, economically feasible and environmental friendly solution to the existing problem is felt vehemently at the core of oil recovery industry. In the light of existing issue, electromagnetic heating technique has emerged as a promising solution and has received greater and greater attention of late. However, most of the studies (especially for inductive heating) have been limited to digital simulations and experiments primarily within the laboratory. In this thesis, preliminary investigations were carried out to confirm the feasibility of a new constructed capacitive compensated inductor coil. Design parameters of the inductor coil were computed and a test model was constructed in the lab for experimental verification of these parameters. The set up comprised a vertical drilling coil design with ferrite core inserted within, thus, creating an intensive electromagnetic field. In this design, a distributed resonating capacitor was proposed to avoid capacitor breakdown due to high voltage. Different coil winding configurations were proposed, constructed and tested by Frequency Response Analysis (FRA) to identify the resonant frequencies. The step response tests and field tests were performed with a square wave supply and were contrasted with the expected induced magnetic field modeled in MatLab. The measurements of the designed coil parameters matched the theoretically computed parameters and the experimental setup verified the advantage of using distributed capacitors, resulting is low breakdown voltage requirement. However, double-layer winding has multiple resonant frequencies and the proposed coil designs suffer from core losses core and winding copper losses. Thus, industrial application of this technology still requires further improvements.

description: The magnetic fields can change their topology through a process known as magnetic reconnection. This process in not only important for understanding the origin and evolution of the large-scale magnetic field, but is seen as a possibly efficient particle accelerator producing cosmic rays mainly through the first order Fermi process. In this work we study the properties of particle acceleration in reconnection zones and show that the velocity component parallel to the magnetic field of test particles inserted in nearly non-resistive magnetohydrodynamic (MHD) domains of reconnection without including kinetic effects, such as pressure anisotropy, the Hall term, or anomalous effects, increases exponentially. Also, the acceleration of the perpendicular component is always possible in such models. We have found that within contracting magnetic islands or current sheets the particles accelerate predominantly through the first order Fermi process, as previously described, while outside the current sheets and islands the particles experience mostly drift acceleration due to magnetic fields gradients. Considering two dimensional MHD models without a guide field, we find that the parallel acceleration stops at some level. This saturation effect is however removed in the presence of an out-of-plane guide field or in three dimensional models. Therefore, we stress the importance of the guide field and fully three dimensional studies for a complete understanding of the process of particle acceleration in astrophysical reconnection environments.

description: I outline a new model of particle acceleration in the current sheet separating the closed from the open field lines in the force-free model of pulsar magnetospheres, based on reconnection at the light cylinder and "auroral" acceleration occurring in the return current channel that connects the light cylinder to the neutron star surface. I discuss recent studies of Pulsar Wind Nebulae, which find that pair outflow rates in excess of those predicted by existing theories of pair creation occur, and use those results to point out that dissipation of the magnetic field in a pulsar's wind upstream of the termination shock is restored to life as a viable model for the solution of the "$σ$" problem as a consequence of the lower wind 4-velocity implied by the larger mass loading.

description: We investigate generalizations of the Charlier polynomials on the lattice $\mathbb{N}$, on the shifted lattice $\mathbb{N}+1-β$ and on the bi-lattice $\mathbb{N}\cup (\mathbb{N}+1-β)$. We show that the coefficients of the three-term recurrence relation for the orthogonal polynomials are related to solutions of the fifth Painlevé equation PV (which can be transformed to the third Painlevé equation). Initial conditions for different lattices can be transformed to the classical solutions of PV with special values of the parameters.

Integrated solar energy harvesting and storage devices

description: Large scale storage of electricity is a vital requirement for the realization of a carbon-neutral electricity grid. This thesis provides a study of integrated solar energy conversion and storage systems in order to increase the efficiency and reduce the utilization cost of solar energy. The efficient performance of photogalvanic cells relies on high dye solubility and selective electrodes with fast electron transfer kinetics. A new configuration is proposed for photogalvanic cells that removes these impractical requirements. Instead of illuminating the device through the electrode a new vertical configuration is employed with light coming between the two electrodes. This way, the light absorption and hence electron generation is spread through the depth of the device which can be adjusted according to the concentration of the dyes to absorb all the incoming photons even with low solubility dyes and slow electrode kinetics. The proposed configuration is mathematically studied and a numerical model is built for detailed analysis that gives practical guidelines for working towards device parameters with high power conversion efficiency. The analysis suggests that upon the realization of highly selective electrodes and an improved dye/mediator couple, an efficiency higher than 13 % should be achievable from the new configuration compared to 3.7 % at best using the conventional approach. Storage however in this system will be challenging due to the characteristic recombination times of dyes and mediators in the same phase. For significant and long-lived storage we designed and demonstrated an integrated solar-battery structure based on two relatively well established technologies of the redox flow battery and the dye-sensitized solar cell. The cell consists of a sensitized electrode in a redox flow battery structure. The design enables independent scaling of power and energy rating of the system thus it is applicable for large scale storage purposes. An areal energy capacity of 52 μWhcm−², charge capacity of 1.2 mAhL−¹, energy efficiency of 78 % and almost perfect Coulombic efficiency are observed for the integrated cell. These values show a 35 times increase in charge capacity and 13 times improvement in areal energy density compared to similar devices.
Quasinormal modes of charged BTZ black holes

description: We investigate the scalar field equation in a (2+1)-dimensional charged BTZ black hole. The quasinormal spectra of the solution are obtained applying two different methods and good convergence between both is achieved. Using the characteristic integration technique we tested the geometry evidencing its stability against linear scalar perturbations. As a consequence a two pattern set of frequencies (families) emerges, one oscillatory and another purely imaginary. In that spectra, the fundamental modes without angular momentum are hugely affected by the presence of the black hole charge surprisedly even for small values of this. Their evolution are controlled by purely imaginary frequencies as in the non-rotating chargeless BTZ case. Similar to others AdS black holes, the fundamental oscillations scale the black hole event horizon and the temperature of the hole (far from maximal charges).

SDSS J141624.08+134826.7: Blue L Dwarfs and Non-Equilibrium Chemistry

description: We present an analysis of the recently discovered blue L dwarf SDSS J141624.08+134826.7. We extend the spectral coverage of its published spectrum to ~4 microns by obtaining a low-resolution L band spectrum with SpeX on the NASA IRTF. The spectrum exhibits a tentative weak CH4 absorption feature at 3.3 microns but is otherwise featureless. We derive the atmospheric parameters of SDSS J141624.08+134826.7 by comparing its 0.7-4.0 micron spectrum to the atmospheric models of Marley and Saumon which include the effects of both condensate cloud formation and non-equilibrium chemistry due to vertical mixing and find the best fitting model has Teff=1700 K, log g=5.5 [cm s-2], fsed=4, and Kzz=10^4 cm2 s-1. The derived effective temperature is significantly cooler than previously estimated but we confirm the suggestion by Bowler et al. that the peculiar spectrum of SDSS J141624.08+134826.7 is primarily a result of thin condensate clouds. In addition, we find strong evidence of vertical mixing in the atmosphere of SDSS J141624.08+134826.7 based on the absence of the deep 3.3 micron CH4 absorption band predicted by models computed in chemical equilibrium. This result suggests that observations of blue L dwarfs are an appealing way to quantitatively estimate the vigor of mixing in the atmospheres of L dwarfs because of the dramatic impact such mixing has on the strength of the 3.3 micron CH4 band in the emergent spectra of L dwarfs with thin condensate clouds.
