description: Additional file 8: Fig. S6. Amplification of spalt from cDNA extracted from zygotes and 24-h post-fertilization Crepidula embryos. Amplification of spalt (Cfo-spalt) was only detected using cDNA from 24-h post-fertilization Crepidula embryos. There was no amplification at all when cDNA from zygotes was used. The gene twist from Crepidula (Cfo-twist) was used as a positive control since twist is detected at both stages of development. PCR products were run on 1% agarose gels.

description: We derive constraints on two-dimensional conformal field theories with higher spin symmetry due to unitarity, modular invariance, and causality. We focus on CFTs with $\mathcal{W}_N$ symmetry in the "irrational" regime, where $c>N-1$ and the theories have an infinite number of higher-spin primaries. The most powerful constraints come from positivity of the Kac matrix, which (unlike the Virasoro case) is non-trivial even when $c>N-1$. This places a lower bound on the dimension of any non-vacuum higher-spin primary state, which is linear in the central charge. At large $c$, this implies that the dual holographic theories of gravity in AdS$_3$, if they exist, have no local, perturbative degrees of freedom in the semi-classical limit.

description: Aleksandrov surfaces are a generalization of two-dimensional Riemannian manifolds, and it is known that every open simply connected Aleksandrov surface is conformally equivalent either to the unit disc (hyperbolic case) or to the plane (parabolic case). We prove a criterion for hyperbolicity of Aleksandrov surfaces which have nice tilings(triangulations) and where negative curvature dominates. We then apply this to generalize a result of Nevanlinna and give a partial answer for his conjecture about line complexes.

description: Orthogonal temporal modes (TMs) form a field-orthogonal, continuous-variable degree of freedom that is in principle infinite dimensional, and create a promising resource for quantum information science and technology. The ideal quantum pulse gate (QPG) is a device that multiplexes and demultiplexes temporally orthogonal optical pulses that have the same carrier frequency, spatial mode, and polarization. The QPG is the chief enabling technology for usage of orthogonal temporal modes as a basis for high-dimensional quantum information storage and processing. The greatest hurdle for QPG implementation using nonlinear-optical, parametric processes with time-varying pump or control fields is the limitation on achievable temporal mode selectivity, defined as perfect TM discrimination combined with unity efficiency. We propose the use of pulsed nonlinear frequency conversion in an optical cavity having greatly different finesses for different frequencies to implement a nearly perfectly TM-selective QPG in a low-loss integrated-optics platform.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

Shock Breakout in Type Ibc Supernovae and Application to GRB 060218/SN 2006aj

description: Recently, a soft black-body component was observed in the early X-ray afterglow of GRB 060218, which was interpreted as shock breakout from the thick wind of the progenitor Wolf-Rayet (WR) star of the underlying Type Ic SN 2006aj. In this paper we present a simple model for computing the characteristic quantities (including energy, temperature, and time-duration) for the transient event from the shock breakout in Type Ibc supernovae produced by the core-collapse of WR stars surrounded by dense winds. In contrast to the case of a star without a strong wind, the shock breakout occurs in the wind region rather than inside the star, caused by the large optical depth in the wind. We find that, for the case of a WR star with a dense wind, the total energy of the radiation generated by the supernova shock breakout is larger than that in the case of the same star without a wind by a factor > 10. The temperature can be either hotter or cooler, depending on the wind parameters. The time-duration is larger caused by the increase in the effective radius of the star due to the presence of a thick wind. Then, we apply the model to GRB 060218/SN 2006aj. We show that, to explain both the temperature and the total energy of the black-body component observed in GRB 060218 by the shock breakout, the progenitor WR star has to have an unrealistically large core radius (the radius at optical depth of 20), larger than 100 Rsun. In spite of this disappointing result, our model is expected to have important applications to the observations on Type Ibc supernovae in which the detection of shock breakout will provide important clues to the progenitors of SNe Ibc.

description: We review recent progress in the determination of the parton distribution functions (PDFs) of the proton, with emphasis on the applications for precision phenomenology at the Large Hadron Collider (LHC). First of all, we introduce the general theoretical framework underlying the global QCD analysis of the quark and gluon internal structure of protons. We then present a detailed overview of the hard-scattering measurements, and the corresponding theory predictions, that are used in state-of-the-art PDF fits. We emphasize here the role that higher-order QCD and electroweak corrections play in the description of recent high-precision collider data. We present the methodology used to extract PDFs in global analyses, including the PDF parametrization strategy and the definition and propagation of PDF uncertainties. Then we review and compare the most recent releases from the various PDF fitting collaborations, highlighting their differences and similarities. We discuss the role that QED corrections and photon-initiated contributions play in modern PDF analysis. We provide representative examples of the implications of PDF fits for high-precision LHC phenomenological applications, such as Higgs coupling measurements and searches for high-mass New Physics resonances. We conclude this report by discussing some selected topics relevant for the future of PDF determinations, including the treatment of theoretical uncertainties, the connection with lattice QCD calculations, and the role of PDFs at future high-energy colliders beyond the LHC.

description: Magnetic bit writing by short-wave magnons without conversion to the electrical domain is expected to be a game-changer for in-memory computing architectures. Recently, the reversal of nanomagnets by propagating magnons was demonstrated. However, experiments have not yet explored different wavelengths and the nonlinear excitation regime of magnons required for computational tasks. We report on the magnetization reversal of individual 20-nm-thick Ni81Fe19 (Py) nanostripes integrated onto 113-nm-thick yttrium iron garnet (YIG). We suppress direct interlayer exchange coupling by an intermediate layer such as Cu and SiO2. Exciting magnons in YIG with wavelengths λ down to 148 nm we observe the reversal of the integrated ferromagnets in a small opposing field of 14 mT. Magnons with a small wavelength of λ = 195 nm, i.e., twice the width of the Py nanostripes, induced the reversal at an unprecedentedly small spin precessional power of about 1 nW after propagating over 15 μm in YIG. Considerations based on dynamic dipolar coupling explain the observed wavelength dependence of magnon-induced reversal efficiency. For an increased power the stripes reversed in an opposing field of only about 1 mT. Our findings are important for the practical implementation of nonvolatile storage of broadband magnon signals in YIG by means of bistable nanomagnets without the need of an appreciable global magnetic field.

description: High resolution remotely sensed bathymetric data is rapidly increasing in volume, but analyzing this data requires a mastery of a complex toolchain of disparate software, including computing derived measurements of the environment. Bathymetric gradients play a fundamental role in energy transport through the seascape. Benthic Terrain Modeler (BTM) uses bathymetric data to enable simple characterization of benthic biotic communities and geologic types, and produces a collection of key geomorphological variables known to affect marine ecosystems and processes. BTM has received continual improvements since its 2008 release; here we describe the tools and morphometrics BTM can produce, the research context which this enables, and we conclude with an example application using data from a protected reef in St. Croix, US Virgin Islands.

The evolution of selfing, inbreeding depression, and polyploidy in the Claytonia perfoliata complex (Portulacaceae)
Creators: name: Rausch, Joseph Howard
Publisher: name: Washington State University
Year: 2008
Subjects: Portulacaceae

description: Polyploidy, the doubling of chromosomes within a species (autopolyploidy) or chromosome doubling in conjunction with hybridization (allopolyploidy), is accepted as having a major role in plant evolution. The ubiquity of polyploidy in plants indicates that polyploidization is a common form of speciation with significant ecological and genetic consequences. The objective of this research is to investigate the evolution of polyploidy; both theoretical and empirical approaches are considered. First, theoretical models are developed to examine the role of selfing, inbreeding depression, and population size on autopolyploid establishment in mixed cytotype populations. This research is presented in Chapter One. The Second Chapter represents a response to a technical comment of Chapter One. Results from both of these chapters show that autopolyploid establishment is facilitated by increased selfing and/or lower inbreeding depression in polyploids relative to diploids. Second, molecular and quantitative population-level approaches are used to empirically examine the relationship between polyploidy, selfing, and inbreeding depression in populations of the Claytonia perfoliata polyploid complex. This is presented in Chapter Three. Results show that inbreeding depression is greatest in outcrossing populations and that ploidy has no significant effects on the level of inbreeding depression. Third, DNA-based data is used to infer phylogenetic relationships and polyploid origins among diploid and polyploidy entities in the Claytonia perfoliata polyploid complex. This is presented in Chapter Four. Results show that both autopolyploidy and allopolyploidy are common within the Claytonia perfoliata complex and that many cytotypes have multiple independent polyploid origins.

Volcanic evolution of the Otowi Member of the Bandelier Tuff, Jemez mountains, New Mexico
Creators: name: Cook, Geoffrey William
Publisher: name: Washington State University
Year: 2009
Subjects: Volcanic ash, tuff, etc -- New Mexico -- Jemez Mountains

description: The 1.61 Ma Otowi Member of the Bandelier Tuff is a compositionally-zoned, high-silica rhyolite tuff showing internal upward decreases in the concentrations of incompatible trace elements. It is associated with the first major episode of collapse at the Valles caldera. Using a comprehensive methodology, the minimum eruptive volume of the Otowi Member has been recalculated at 335 km3 DRE. The plinian phase has been calculated at 45 km3 DRE. Based on these minimum calculations, it is likely that the original volume of the deposit was greater than 500 km3 DRE. Prior studies suggested that the Otowi eruption began with a single, central vent and transitioned quickly to multiple ring vents as collapse ensued. This model has been evaluated by comparing vertical profiles in pumice chemistry and lithic abundances in outflow sheet sections around the caldera. Lithic distributions are surprisingly uniform around the caldera. Thus, a new model for eruption of the Otowi Member is presented here in which a single, central vent was responsible for the majority of the eruption. Lithic and chemical evidence indicate a vent shift late in the eruption towards the northeast as collapse ensued. However, multiple ring vents are not evident in the data. In addition, volume calculations of chemical types in the Otowi ignimbrites indicate a roughly equal tri-part distribution. This volume-constrained chemical data may prove useful in future petrogenetic studies on the Otowi Member.

Spirituality and race in the counseling preferences of African American adults
Creators: name: Easterly, Talitha Parish
Publisher: name: Washington State University

Subjects: Cross-cultural counseling

description: Research on counseling preferences of African American adults was extended to include spirituality as a counseling variable. This study investigated the effects of African American spiritual identification and counselor characteristics (i.e., race and spirituality) on favorability ratings in determining counselor preference among African American adults. Respondents included 205 African American adults who completed the TRIOS Spirituality Subscale (Jones, 2003), an assessment of African American spirituality that is a part of the full TRIOS-C Index, and rated and responded to 4 vignettes describing different counseling conditions using the Counselor Favorability Questionnaire (CFQ; Want, 1995). Data was analyzed using a Repeated Measures MANCOVA for main and interaction effects. This study provides support for similar race counselor preference among African American adults. In consideration of within-group variability, this study found that African American participants with a higher level of spiritual identification expressed a much stronger preference for an African American counselor compared to a Caucasian American counselor. This study did not find a preference based on the counselor variable of spirituality and no support was found for the interactions between race of counselor, spiritual encouragement by counselor, and participants' level of spiritual identification.

description: We provide an update for the astrometric solution for the Type II supernova progenitor Betelgeuse using the revised Hipparcos Intermediate Astrometric Data (HIAD) of van Leeuwen, combined with existing VLA and new e-MERLIN and ALMA positions. The 2007 Hipparcos refined abscissa measurements required the addition of so-called Cosmic Noise of 2.4 mas to find an acceptable 5-parameter stochastic solution. We find that a measure of radio Cosmic Noise should also be included for the radio positions because surface inhomogeneities exist at a level significant enough to introduce additional intensity centroid uncertainty. Combining the 2007 HIAD with the proper motions based solely on the radio positions leads to a parallax of $π= 5.27\pm 0.78$ mas ($190^{+33}_{-25}$ pc), smaller than the Hipparcos 2007 value of $6.56\pm 0.83$ mas ($152^{+22}_{-17}$ pc; van Leeuwen 2007). Furthermore, combining the VLA and new e-MERLIN and ALMA radio positions with the 2007 HIAD, and including radio Cosmic Noise of 2.4 mas, leads to a nominal parallax solution of $4.51 \pm 0.80$ mas ($222^{+48}_{-34}$ pc), which while only $0.7σ$ different from the 2008 solution of Harper et al. it is $2.6σ$ different from the solution of van Leeuwen. An accurate and precise parallax for Betelgeuse is always going to be difficult to obtain because it is small compared to the stellar angular diameter ($θ=44$ mas). We outline an observing strategy, utilizing future mm and sub-mm high-spatial resolution interferometry that must be used if substantial improvements in precision and accuracy of the parallax and distance are to be achieved.
Spatial development of the cytoplasmic compartments for single cell C4 photosynthesis, and mechanisms of tolerance to salinity in Bienertia sinuspersici
Creators: name: Park, Joonho
Publisher: name: Washington State University
Year: 2008
Subjects: Chenopodiaceae

description: Until recent discovery of single cell C4 (SC-C4) photosynthesis in the family Chenopodiaceae, C4 photosynthesis had been linked to Kranz type leaf anatomy. Anatomical, biochemical and cell biological approaches are being made to characterize SC-C4 photosynthesis in terrestrial plants. Here, these techniques were employed in three chapters to further understanding of the SC-C4. Since all SC-C4 species are found in saline, semi desert areas, the first objective was to study the mechanism of tolerance to salinity. Therefore, synthesis of compatible solutes, and other potential salt resistant mechanisms were discussed relative to biochemistry and physiology. SC-C4 species have one type of chlorenchyma cell (CC), while Kranz types have two types of CC, mesophyll and bundle sheath cells, to run C4 photosynthesis. Instead of having two cells, SC-C4 type has dimorphic chloroplasts in one cell type. One type of chloroplast is located in the peripheral cytoplasm, while the other type is located in a central cytoplasmic compartment. The spatial compartmentation of organelles during leaf development is a critical step for C4 photosynthesis. In the second objective, the positioning of cellular components during development of CC was studied in B.sinuspersici. Various fluorescent dyes targeted to different cellular compartments were used to observe spatial compartmentation of organelles and development of the vacuole which resulted in a model of how the C4 system forms. Using whole cell immunolocalization techniques, I also showed how structures of the cytoskeleton affect the positioning of organelles during the development of CC. In addition, to determine if environmental conditions could alter the structure of CC, different light treatments were performed. B.sinuspersici was chosen for further analyses using genomics and proteomics approaches. To study the gene expression pattern in chlorenchyma cells, a cDNA library was constructed from isolated CC. Two sequencing methods were used, a conventional method and 454 sequencing. In addition, to determining the expression pattern in CC, a Mudpit technique was used. Based on both transcriptomics and proteomics data, we discuss differences between C4 Kranz and SC-C4 species. Combined, these studies contribute to our understanding of the SC-C4 photosynthesis at physiological, developmental, and biochemical levels. Identifying relevant genetic information which governs the novel formation of SC-C4 photosynthesis in B.sinuspersici may be useful in developing strategies to genetically modify certain economically important C3 species to perform C4. This could provide increased tolerance to certain abiotic stresses resulting in higher photosynthesis and increased crop yield in certain environments.

We also study two functionals closely related to the entropy integral. First, their asymptotic behavior is completely described for weights $w$ in the Bernstein class. Then, as for the entropy, we obtain asymptotic upper bounds for these two functionals when $w(x)$ belongs to the Szegő class. In each case, we give conditions for these upper bounds to be attained.

description: Recently, anomalous Floquet topological phases without static counterparts have been observed in different systems, where periodically driven models are realized to support a winding number of 1 and a pair of edge modes in each quasienergy gap. Here, we focus on cold atomic gases in optical lattices and propose a novel driving scheme that breaks rotation symmetry but maintains inversion symmetry of the instantaneous Hamiltonian, and discover a novel type of anomalous Floquet topological phase with winding number larger than 1. By analyzing the condition of band touching under symmetry constraint, we map out the phase diagram exactly by varying the driving parameters and discuss the quasienergy spectra of typical topological phases, which can present multiple pairs of edge modes within a single gap. Finally, we suggest to characterize the topology of such phases by detecting the band inversion surfaces via quench dynamics.

description: A systematic approach for the model building of Generalized Parton Distributions (GPDs), based on their overlap representation within the DGLAP kinematic region and a further covariant extension to the ERBL one, is applied to the valence-quark pion's case, using light-front wave functions inspired by the Nakanishi representation of the pion's Bethe-Salpeter amplitudes (BSA). This simple but fruitful pion's GPD model illustrates the general model building technique and, in addition, allows for the ambiguities related to the covariant extension, grounded on the Double Distribution (DD) representation, to be constrained by requiring a soft-pion theorem to be properly observed.

description: The purpose of the study was to examine the portrayal of teachers featured in children's literature as an avenue for illuminating embedded messages relative to care in the context of teaching and learning. The study employed two analytical frameworks relational epistemology and critical literacy. The data set consisted of 38 children's books, specifically picture storybooks, transitional books, and children's novels. The books targeted for inclusion in the study were those that had: 1) an original publication date between 1998 and 2008, 2) an elementary school setting, 3) a teacher featured as a central character, and 4) a storyline that depicted a teacher teaching. There were three coding categories. The first was social identities specifically coding for teacher gender, race, ethnicity, and culture. The second was personal dispositions related to caring. The third coding category focused on the pedagogical practices and approaches of the teachers featured in children's literature. Overall, the results indicated that children's books published within the last ten years reflect a positive trend in the portrayal of teachers. The findings revealed several key points relative to the coding categories. Female characters continue to dominant the portrayal of elementary teachers featured in children's literature. The majority of the fictional teachers featured in the literary texts were portrayed as having a light skin tone. Finally, across the texts analyzed the portrayal of teachers reflect an absence of pedagogical approaches and practices that incorporate caring as conveyed in different cultures. With an over representation of White European-American females and an under representation of cultures beyond the dominant mainstream culture, the conclusion drawn was that the teachers featured in children's literature does not accurately reflect the reality of the teachers teaching in elementary schools today. As such, this study brought awareness to the narrow perception of teaching and teachers. In sum, the significance of this study was the awareness brought forth as to the positive trend in the portrayal of teachers yet a narrow perception of what it means to be a caring teacher.

description: Superconducting bulks, acting as high-field permanent magnets, are promising for many applications. An important effect in bulk permanent magnets is crossed-field demagnetization, which can reduce the magnetic field in superconductors due to relatively small transverse fields. Crossed-field demagnetization has not been studied in sample shapes such as rectangular prisms or cubes. This contribution presents a study based on both 3D numerical modelling and experiments. We study a cubic Gd-Ba-Cu-O bulk superconductor sample of size 6 mm magnetized by field cooling in an external field of around 1.3 T, which is later submitted to crossed-field magnetic fields of up to 164 mT. Modelling results agree with experiments, except at transverse fields 50\% or above of the initial trapped field. The current paths present a strong 3D nature. For instance, at the mid-plane perpendicular to the initial magnetizing field, the current density in this direction changes smoothly from the critical magnitude, ${J_c}$, at the lateral sides to zero at a certain penetration depth. This indicates a rotation of the current density with magnitude ${J_c}$, and hence force free effects like flux cutting are expected to play a significant role.

description: Scientists have long speculated about the potential habitability of Venus, not at the 700K surface, but in the cloud layers located at 48-60 km altitudes, where temperatures match those found on Earth's surface. However, the prevailing belief has been that Venus' clouds cannot support life due to the cloud chemical composition of concentrated sulfuric acid-a highly aggressive solvent. In this work, we study 20 biogenic amino acids at the range of Venus' cloud sulfuric acid concentrations (81% and 98% w/w, the rest water) and temperatures. We find 19 of the biogenic amino acids we tested are either unreactive (13 in 98% w/w and 12 in 81% w/w) or chemically modified in the side chain only, after four weeks. Our major finding, therefore, is that the amino acid backbone remains intact in concentrated sulfuric acid. These findings significantly broaden the range of biologically relevant molecules that could be components of a biochemistry based on a concentrated sulfuric acid solvent.

description: The Ricochet experiment seeks to measure Coherent (neutral-current) Elastic Neutrino-Nucleus Scattering using dark-matter-style detectors with sub-keV thresholds placed near a neutrino source, such as the MIT (research) Reactor (MITR), which operates at 5.5 MW generating approximately 2.2e18 neutrinos/second in its core. Currently, Ricochet is characterizing the backgrounds at MITR, the main component of which comes in the form of neutrons emitted from the core simultaneous with the neutrino signal. To characterize this background, we wrapped Bonner cylinders around a He-3 thermal neutron detector, whose data was then unfolded via a Markov Chain Monte Carlo (MCMC) to produce a neutron energy spectrum across several orders of magnitude. We discuss the resulting spectrum and its implications for deploying Ricochet at the MITR site as well as the feasibility of reducing this background level via the addition of polyethylene shielding around the detector setup.

description: Measuring behavior that has a social stigma attached to it is difficult because people do not respond exactly the way they behave. This is due to the apprehension that people have about disclosing such behaviors. The repercussion that they may face is a powerful fact that mitigates their responses. Therefore, to study specific contexts such as unethical behavior, researchers have devised techniques to keep the respondents anonymous (Dalton & Metzger, 1992). In this study, unethical behavior is measured by using two techniques that are compared in an online setting: unmatched count technique (UCT) and a nominal technique. Using these techniques, the impact of technology on the disclosure apprehension is studied. Disclosure apprehension is a perception that has positive and negative valence for a subject who is faced with a request to disclose sensitive information. The results show that UCT is better for obtaining disclosure of sensitive information. Individual traits such as neuroticism and openness to experience along with media characteristics (persistence and interactivity) were shown to affect disclosure apprehension. Persistence is the ability of the media to retain content that passes through it. Both persistence and interactivity were found to have significant overall effects.

description: The mechanisms responsible for heating the extended atmospheres of early-M spectral-type supergiants are poorly understood. So too is the subsequent role these mechanisms play in driving the large mass-loss rates of these stars. Here we present ALMA long (i.e., $\sim$16 km) baseline 338 GHz (0.89 mm) continuum observations of the free-free emission in the extended atmosphere of the M2 spectral-type supergiant Betelgeuse. The spatial resolution of 14 mas exquisitely resolves the atmosphere, revealing it to have a mean temperature of 2760 K at $\sim$1.3 R$_{\star}$, which is below both the photospheric effective temperature ($T_{\textrm{eff}} = 3690$ K) and the temperatures at $\sim$$2 $R$_{\star}$. This is unambiguous proof for the existence of an inversion of the mean temperature in the atmosphere of a red supergiant. The emission is clearly not spherically symmetric with two notable deviations from a uniform disk detected in both the images and visibilities. The most prominent asymmetry is located in the north-east quadrant of the disk and is spatially resolved showing it to be highly elongated with an axis-ratio of 2.4 and occupying $\sim$$5\%$ of the disk projected area. Its temperature is approximately 1000 K above the measured mean temperature at 1.3 R$_{\star}$. The other main asymmetry is located on the disk limb almost due east of the disk center and occupies $\sim$$3\%$ of the disk projected area. Both emission asymmetries are clear evidence for localized heating taking place in the atmosphere of Betelgeuse. We suggest that the detected localized heating is related to magnetic activity generated by large-scale photospheric convection.

description: We propose a method for the implementation of one-way quantum computing in superconducting circuits. Measurement-based quantum computing is a universal quantum computation paradigm in which an initial cluster-state provides the quantum resource, while the iteration of sequential measurements and local rotations encodes the quantum algorithm. Up to now, technical constraints have limited a scalable approach to this quantum computing alternative. The initial cluster state can be generated with available controlled-phase gates, while the quantum algorithm makes use of high-fidelity readout and coherent feedforward. With current technology, we estimate that quantum algorithms with above 20 qubits may be implemented in the path towards quantum supremacy. Moreover, we propose an alternative initial state with properties of maximal persistence and maximal connectedness, reducing the required resources of one-way quantum computing protocols.
