description: Let $\mathbf{F}_q$ be a finite field of $q$ elements. We show that the normalized Jacobi sum $q^{-(m-1)/2}J(χ_1,\dots,χ_m)$ ($χ_1\dotsm χ_m$ nontrivial) is asymptotically equidistributed on the unit circle, when $χ_1\in \mathcal{A}_1,\dots, χ_m\in \mathcal{A}_m$ run through arbitrary sets of nontrivial multiplicative characters of $\mathbf{F}_q^\times$, if $\#\mathcal{A}_1\ge q^{\frac{1}{2}+ε}$, $\#\mathcal{A}_2 \ge (\log q)^{\frac{1}δ-1}$ for $ε>δ>0$ fixed and $q\to \infty$ or if $\#\mathcal{A}_1\#\mathcal{A}_2/q\to \infty$. This extends previous results of Xi, Z. Zheng, and the authors.

description: We consider a run an tumble particle with two velocity states $\pm v_0$, in an inhomogeneous force field $f(x)$ in one dimension. We obtain exact formulae for its velocity $V_L$ and diffusion constant $D_L$ for arbitrary periodic $f(x)$ of period $L$. They involve the "active potential" which allows to define a global bias. Upon varying parameters, such as an external force $F$, the dynamics undergoes transitions from non-ergodic trapped states, to various moving states, some with non analyticities in the $V_L$ versus $F$ curve. A random landscape in the presence of a bias leads, for large $L$, to anomalous diffusion $x \sim t^μ$, $μ<1$, or to a phase with a finite velocity that we calculate.

description: Despite the proliferation of inclusive policies on disability, there remains little academic literature grounded in the field of international relations that explains under which domestic socio-political conditions international disability rights norms are likely to flourish. This paper asks, ―Which factors contribute to variation in the domestic promotion of political participation and social inclusion for persons with disabilities, as exemplified by the social model of disability and the UN Convention on the Rights of Persons with Disabilities (CRPD)?‖ The primary focus of the paper is to uncover certain historical processes that influence democratic and relatively wealthy countries to engage with international disability rights instruments by embracing the social-model language of the CRPD in their disability-related laws. With respect to this question, the author distinguishes the United States from India- two large, democratic countries with stable economies, which have adopted very different models within their disability laws in the 1990s. The case studies reveal that, although the U.S.`s disability laws comply with the standards of the CRPD, domestic tensions have hindered its participation as a leader in international human rights treaties. On the other hand, India`s original disability law, which does not embrace the fundamental principles of the CRPD, was a product of on-going transitions in India`s foreign policy and efforts to build a more globally engaged capitalist economy.

description: In the Standard Model, all massive elementary particles acquire their masses by coupling to a background Higgs field with a non-zero vacuum expectation value. What is often overlooked is that each massive particle is also a source of the Higgs field. A given particle can in principle shift the mass of a neighboring particle. The mass shift effect goes beyond the usual perturbative Feynman diagram calculations which implicitly assume that the mass of each particle is rigidly fixed. Local mass shifts offer a unique handle on Higgs physics since they do not require the production of on-shell Higgs bosons. We provide theoretical estimates showing that the mass shift effect can be large and measurable, especially near pair threshold, at both the Tevatron and the LHC.

description: The Itajaí Basin located in the southern border of the Luís Alves Microplate is considered as a peripheral foreland basin related to the Dom Feliciano Belt. It presents an excellent record of the Ediacaran period, and its upper parts display the best Brazilian example of Precambrian turbiditic deposits. The basal succession of Itajaí Group is represented by sandstones and conglomerates (Baú Formation) deposited in alluvial and deltaic-fan systems. The marine upper sequences correspond to the Ribeirão Carvalho (channelized and non-channelized proximal silty-argillaceous rhythmic turbidites), Ribeirão Neisse (arkosic sandstones and siltites), and Ribeirão do Bode (distal silty turbidites) formations. The Apiúna Formation felsic volcanic rocks crosscut the sedimentary succession. The Cambrian Subida leucosyenogranite represents the last felsic magmatic activity to affect the Itajaí Basin. The Brusque Group and the Florianópolis Batholith are proposed as source areas for the sediments of the upper sequence. For the lower continental units the source areas are the Santa Catarina, São Miguel and Camboriú complexes. The lack of any oceanic crust in the Itajaí Basin suggests that the marine units were deposited in a restricted, internal sea. The sedimentation started around 600 Ma and ended before 560 Ma as indicated by the emplacement of rhyolitic domes. The Itajaí Basin is temporally and tectonically correlated with the Camaquã Basin in Rio Grande do Sul and the Arroyo del Soldado/Piriápolis Basin in Uruguay. It also has several tectono-sedimentary characteristics in common with the African-equivalent Nama Basin.
Conformal Algebra and Physical States in Non-critical 3-brane on R*S^3

description: A world-volume model of non-critical 3-brane is quantized in a strong coupling phase where fluctuations of the conformal mode become dominant. This phase, called the conformal-mode dominant phase, is realized at the very high energy far beyond the Planck mass scale. We separately treat the conformal mode and the traceless mode and quantize the conformal mode "non-perturbatively", while the traceless mode is treated in the perturbation which is renormalizable and asymptotically free. In the conformal-mode dominant phase, the coupling of the traceless mode vanishes and the world-volume dynamics is described as a four dimensional conformal field theory (CFT_4). We canonically quantize this model on R*S^3 where the dynamical metric fields are expanded using spherical tensor harmonics on S^3. Conformal charges and conformal algebra are constructed. They give strong constraints on physical states. We find that all negative-metric modes are related to positive-metric modes through the charges so that they are not independent physical modes themselves. An infinite number of physical states satisfying the conformal invariance conditions are constructed. In appendix, we construct spherical vector, tensor harmonics on S^3 in the useable form using Wigner D-functions and Clebsch-Gordan coefficients and calculate integrals of their products.

description: The Nordström-Vlasov system describes the dynamics of a self-gravitating ensemble of collisionless particles in the framework of the Nordström scalar theory of gravitation. We prove existence and uniqueness of classical solutions of the Cauchy problem in three dimensions and establish a condition which guarantees that the solution is global in time. Moreover, we show that if one changes the sign of the source term in the field equation, which heuristically corresponds to the case of a repulsive gravitational force, then solutions blow up in finite time for a large class of initial data. Finally, we prove global existence of classical solutions for the one dimensional version of the system with the correct sign in the field equation.

description: We derive the exchange currents of pseudoscalar, vector, and scalar mesons from Feynman diagrams, and use them to calculate the magnetic form factors of nucleon and $Δ(1232)$. The magnetic moments and electromagnetic radii are obtained by using those form factors and the parameters determined from the masses of nucleon and $Δ(1232)$. We find the magnetic moments and electromagnetic radii of nucleon and $Δ(1232)$ can be produced very well in the extended Goldstone-boson-exchange model (GBE) in which all of pseudoscalar, vector and scalar meson nonet are included. The magnetic moments of $Δ(1232)$ are closer to experiment values and results from lattice calculation than the results obtained by the model without other mesons except for pion and sigma.

description: We use light-like Wilson loops and the AdS/CFT correspondence to compute the anomalous dimensions of twist two operators in the cascading (Klebanov-Strassler) theory. The computation amounts to find a minimal surface in the UV region of the KS background which is described by the Klebanov-Tseytlin solution. The result is similar to the one for SU(N), N=4 SYM but with N replaced by an effective, scale dependent N. We perform also a calculation using a rotating string and find agreement. In fact we use a double Wick rotated version of the rotating string solution which is an Euclidean world-sheet ending on a light-like line in the boundary. It gives the same result as the rotating string for the N=4 case but is more appropiate than the rotating string in the N=1 case.

description: There is growing consensus that at least some subtypes of ADHD may be associated with certain sleep difficulties and that these difficulties may contribute to the symptoms of the disorder. Recent sleep research has indicated that the sleep physiology of solitary sleeping infants differs from that of infants who cosleep with an adult. This study explored the potential link between infant sleep and later ADHD symptoms using survey methodology. The relationships between various sleep arrangements in infancy, along with relevant covariates, were examined in relation to each other and to symptoms of ADHD in children ages 3 to 6. No relationship was found between sleep arrangements at birth and later ADHD symptoms, however, several significant relationships were found among the other variables. The results of this study demonstrate the complex nature of the relationships between variables known to affect the risk for ADHD symptoms.

description: Deciding on the unimodality of a dataset is an important problem in data analysis and statistical modeling. It allows to obtain knowledge about the structure of the dataset, ie. whether data points have been generated by a probability distribution with a single or more than one peaks. Such knowledge is very useful for several data analysis problems, such as for deciding on the number of clusters and determining unimodal projections. We propose a technique called UU-test (Unimodal Uniform test) to decide on the unimodality of a one-dimensional dataset. The method operates on the empirical cumulative density function (ecdf) of the dataset. It attempts to build a piecewise linear approximation of the ecdf that is unimodal and models the data sufficiently in the sense that the data corresponding to each linear segment follows the uniform distribution. A unique feature of this approach is that in the case of unimodality, it also provides a statistical model of the data in the form of a Uniform Mixture Model. We present experimental results in order to assess the ability of the method to decide on unimodality and perform comparisons with the well-known dip-test approach. In addition, in the case of unimodal datasets we evaluate the Uniform Mixture Models provided by the proposed method using the test set log-likelihood and the two-sample Kolmogorov-Smirnov (KS) test.

Short-term fluctuations in vegetation and phytoplankton during the Middle Eocene greenhouse climate: a 640-kyr record from the Messel oil shale (Germany)

description: The Palaeogene was the most recent greenhouse period on Earth. Especially for the Late Palaeocene and Early Eocene, several superimposed short-term hyperthermal events have been described, including extremes such as the Palaeocene–Eocene Thermal Maximum. Major faunal and floral turnovers in the marine and terrestrial realms were recorded in association with these events. High-resolution palynological analysis of the early Middle Eocene maar lake sediments at Messel, near Darmstadt, Germany, provides an insight into the dynamics of a climax vegetation during the Middle Eocene greenhouse climate in a time span without significant climatic excursions. Numerical techniques like detrended correspondence analysis and wavelet analysis have been applied to recognize cyclic fluctuations and long-term trends in the vegetation through a time interval of approximately 640 kyr. Based on the numerical zoning of the pollen diagram, three phases in the development of the vegetation may be distinguished. Throughout these phases, the climax vegetation did not change substantially in qualitative composition, but a trend towards noticeably less humid conditions probably in combination with a drop of the water level in the lake may be recognized. A shift in algal population from the freshwater dinoflagellate cyst Messelodinium thielepfeifferae to a dominance of Botryococcus in the uppermost part of the core is interpreted as a response to changes in acidity and nutrient availability within the lake. Time series analyses of pollen assemblages show that variations in the Milankovitch range of eccentricity, obliquity and precession can be distinguished. In addition, fluctuations in the sub-Milankovitch range are indicated. This demonstrates that floral changes during steady depositional conditions in the Middle Eocene of Messel were controlled by orbital forcing.
title: The Ultrastructural and Abnormal Calcium Handling in Pulmonary Vein Sleeve Cells, Atrial and Ventricular Myocytes During Ageing
Creators: name: Masoud, Said

description: Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, with age being a significant risk factor. It is well established now that electric activities originating from pulmonary vein sleeve cells (PVCs) initiate AF. Factors that are involved in maintaining AF include structural remodelling and abnormal Ca2+ handling in PVCs and atrial myocytes. Whilst structural changes and alterations in the Ca2+ homeostasis have been described previously in atrial myocytes, similar studies are still lacking in PVCs. Thus, this thesis investigated structural remodelling and Ca2+ handling, particularly in PVCs from 3- and 24month-old mice.

Using immunohistochemical and electron microscopy (EM) studies, this thesis revealed that PVCs just like atrial and ventricular myocytes, express RyR2, Cx40, and Cx43. Whilst RyR2 and Cx43 expressions did not change with age, Cx40 expression was found to deteriorate during ageing. Additionally, EM studies showed significant alterations in mitochondria which increased in size and numbers during ageing. Unlike PVCs, mitochondria in atrial myocytes were enlarged but did not increase in numbers during ageing. Mitochondria in ventricular myocytes did not deteriorate with age.

This study also showed that Ca2+ homeostasis in PVCs is disrupted during ageing. PVCs from aged mice had an increased frequency and duration of spontaneous Ca2+ waves, with reduced amplitude, less able to follow electrical pacing and had higher basal ROS levels compared to PVCs from young mice.

Additional studies attempted to induce ageing chemically with hydroxyurea (HU) in neonatal rat ventricular myocytes (NRVMs). HU inhibited pacing ability, induced autophagy and increased inducible ROS. Although some changes in chemically ageing model were similar to those in aged PVCs, further studies are needed to fully establish whether HU can induce ageing in NRVMs.

In conclusion, this study showed that structural remodelling and Ca2+ homeostasis differs in PVCs during ageing which may facilitate the occurrence of arrhythmias.

description: Advantages in several fields of research and industry are expected with the rise of quantum computers. However, the computational cost to load classical data in quantum computers can impose restrictions on possible quantum speedups. Known algorithms to create arbitrary quantum states require quantum circuits with depth O(N) to load an N-dimensional vector. Here, we show that it is possible to load an N-dimensional vector with a quantum circuit with polylogarithmic depth and entangled information in ancillary qubits. Results show that we can efficiently load data in quantum devices using a divide-and-conquer strategy to exchange computational time for space. We demonstrate a proof of concept on a real quantum device and present two applications for quantum machine learning. We expect that this new loading strategy allows the quantum speedup of tasks that require to load a significant volume of information to quantum devices.

description: The red shouldered soapberry bug Jadera haematoloma (Heteroptera:Rhopalidae) has provided an unique opportunity to study the genetic basis for phenotypic differences between populations. Among J. haematoloma in Southern Florida, individuals are found feeding and reproducing on the native balloon vine (Cardiospermum sp.). Recently derived (~60 years) populations also feed on goldenrain tree (Koelreuteria sp.). As a result of this host shift, rostrum length in derived J. haematoloma has declined from almost 70% of body length to roughly 50%. This study looks into the development of the mouthparts, focusing on three genes- Distal-less, dachshund, and homothorax known to play a role in the mouthpart development in another heteropteran, Oncopeltus fasciatus. RNA interference was used to characterize the roles of these genes in J. haematoloma mouthpart development. Treatment groups for all the genes resulted in phenotypic differences from the control group. Maternal RNAi for Dll resulted in hatchlings without proper appendage development. Juvenile RNAi showed that Dll significantly reduced labrum length and dac showed a significant reduction in labium segment 3 and 4. It has been concluded that Distal-less, dachshund, and homothorax play a developmental role in J. haematoloma mouthparts and that the genes have a conserved function between species.

description: Comparison of periodic B dopants with a random alloy of substitional boron in diamond is carried out using several supercells and the coherent potential approximation (CPA) for the random alloy case. The main peak in the B local density of states is shifted to lower binding energy compared to the corresponding C peak in intrinsic diamond. In supercells, this shows up as strongly B-character bands split from bulk C bands away from the zone center,in an energy region around -1 eV. Even for a 4*4*4 supercell (BC$_{127}$), effects of the dopant order are evident in the form of primarily B-character bands just below the Fermi level at the supercell zone boundary. The bands resulting from the CPA are of continuous mixed C-B character. They resemble virtual crystal bands, but broadened somewhat reflecting the disorder-induced lifetime, and are consistent with angle-resolved photoemission band maps. The B character is 1.7 times larger than for C (per atom) near the top of the valence bands for CPA, and roughly the same for supercells. CPA results are particularly useful since they characterize the wavevector and energy dependence of disorder broadening.

The starting points are the recently-proposed amplitudes for the scattering among the physical, massive excitations of the theory. The analysis fully confirms the correctness of the S-matrix. We also derive closed sets of functional relations for the pseudoenergies (Y-systems). These relations are shown to be the k-->infinity limit of the Sp(k+1)-related systems studied some years ago by Kuniba and Nakanishi in the framework of lattice models.

title: Carnosine metabolism and function in the thoroughbred horse
Creators: name: Dunnett, Mark
Publisher: name: The Open University
Year: 1996

description: Thoroughbred horseracing involves high-intensity exercise characterized by the production and accumulation of hydrogen (H+) ions within the skeletal muscles. Without a system for maintaining acid-base balance the consequential accumulation of H+ ions within the working muscles would produce a rapid decline in intra-cellular pH with a concomitant impairment of the contractile process. Carnosine (ß-alanyl-L-histidine, pKa 6.83) occurs at high concentration in equine muscle where it functions as an effective H+ ion buffer at physiological pH.

 High-performance liquid chromatography analytical methods were developed for carnosine and used to investigate its distribution and metabolism in equine fluids and tissues, with emphasis on type 1, IIA and IIB muscle fibres. Foals and yearlings had significantly lower plasma carnosine concentrations than older horses. Plasma carnosine concentration showed little change during normal feeding and high-intensity exercise, however, episodes of equine exertional rhabdomyolysis produced large increases. Carnosine concentrations in tissues, such as the heart, liver and intestine were 10 to 100-fold lower than in skeletal muscle. Carnosine displayed a heterogeneous distribution within skeletal muscle. Its concentration in type IIA and 1113fi bres was approximately 5-fold higher than in type I fibres.

 Extensive, partly anaerobic training produced a 2-fold increase in the carnosine concentration in type IIA fibres, and an increase, although non-significant, in type I and IIB fibres. Thirty days of dietary ß-alanine and histidine supplementation produced an adaptive increase in ß-alanine and histidine bioavailability, and significant increases in the carnosine concentration in type IIA and IIB fibres.

 A greater skeletal muscle carnosine concentration via training and/or ß-alanine and histidine supplementation would produce a corresponding increase in H+ ion buffering capacity, which may reduce the rate of metabolic acidosis during high-intensity exercise, and possibly delay the subsequent onset of localized muscle fatigue.

The linked data allow us to measure SNAP participation more accurately than is possible with household survey data while also allowing us to estimate SNAP eligibility in the population. The large sample size of the ACS enables us to provide a breakdown of access rates by subgroups within the State and for demographic subgroups within the largest counties in Texas. The report provides Texas SNAP administrators with a profile of individuals who may benefit from expanded outreach.

description: Die Arbeit befasst sich mit der Erstellung eines Grundlagenpapiers für die Entwicklung eines schulischen Integrationskonzepts. Die Literatur und die gesetzlichen Grundlagen bzw. Richtlinien liefern dazu eine Fülle von Empfehlungen, welche die Grundlage dieser Arbeit bilden. Basierend darauf wird mit Hilfe einer Dokumentenanalyse und einem Experteninterview, welche mittels qualitativer Inhaltsanalyse ausgewertet wurden, ein Grundlagenpapier erstellt. Dieses kann zur Erstellung eines schulischen Integrationskonzepts herangezogen werden. Ein erster Schritt bei der Entwicklung eines schulischen Integrationskonzepts ist die Zusammenstellung einer Projektgruppe, welche das Konzept zielgerichtet und aufgrund einer gemeinsamen Wertehaltung entwickelt. Dabei sollte das Integrationskonzept zwei Schwerpunkte setzen. Zum einen sollte auf die ganzheitliche Förderung aller Schülerinnen und Schüler fokussiert werden. Ein anderer Schwerpunkt stellt der Umgang mit den spezifischen und individuellen Fördermassnahmen einzelner Schülerinnen und Schüler mit und ohne Lernzielanpassung dar. Ein Integrationskonzept sollte demnach die gemeinsame Praxis flexibel darstellen können und dennoch ausreichende Verbindlichkeit bieten.

We investigated the chemical composition of two Peru Balsam samples, one historical and one modern, using gas chromatography/mass spectrometry to identify the active ingredients responsible for its pharmaceutical properties. Both Peru Balsam specimens investigated had similar compositions, showing the stability of the substance. Components identified are effective against scabies, exhibit antimicrobial activity and aid skin penetration. These properties are consistent with historical uses of Peru Balsam. Several ingredients are also known allergens. This study, combining chemical information with scientific literature related to pharmaceutical properties of natural substances, represents a breakthrough in the elucidation of active ingredients in Peru Balsam.

description: Quantum mechanical models with a minimal length are often described by modifying the commutation relation between position and momentum. Although this represents a small complication when described in momentum space, at least formally, the (quasi-)position representation acquires numerous issues, source of misunderstandings. In this work, we review these issues, clarifying some of the aspects of minimal length models, with particular reference to the representation of the position operator.

description: An estimated 85.5 percent of American households were food secure throughout the entire year in 2012, meaning that they had access at all times to enough food for an active, healthy life for all household members. The remaining households (14.5 percent) were food insecure at least some time during the year, including 5.7 percent with very low food security—meaning that the food intake of one or more household members was reduced and their eating patterns were disrupted at times during the year because the household lacked money and other resources for food. The change in food insecurity overall (from 14.9 percent in 2011) was not statistically significant. The prevalence rate of very low food security was unchanged from 5.7 percent in 2011. Children were food-insecure in 10.0 percent of households with children in 2012, unchanged from 2011. In 2012, the typical food-secure household spent 26 percent more on food than the typical food-insecure household of the same size and household composition. Fifty-nine percent of all food- insecure households participated in one or more of the three largest Federal food and nutrition assistance programs during the month prior to the 2012 survey.

description: Following the Healthy, Hunger-Free Kids Act of 2010, USDA instituted many changes to the National School Lunch Program (NSLP). School lunches have had to meet new nutrition standards since the fall of 2012. Using data collected as part of the 2005 School Nutrition and Dietary Assessment III, this report examines whether students who attended schools serving more fruits and vegetables, in amounts that would meet the new standards, actually ate more of them than students at schools that did not. Student consumption data were matched by date to lunch menu records for the same day. Tobit models were used to estimate consumption of fruits and vegetables in school lunches by NSLP participants, controlling for other characteristics of students and school food operations. Students in schools that offered more fruits and vegetables and in quantities that met daily standards consumed greater quantities of many of those foods. But most students did not eat any of the offered fruits and vegetables in 2005, suggesting that additional methods may need to be considered in order to meet nutritional goals.
title: Exploring the clinical guideline development process : influences and interactions

description: Evidence-based clinical guidelines serve as an important support for medical decision-making. To date, research on clinical guidelines has focused mainly on guideline development methodology and the extent of guideline implementation. How guideline groups utilise various forms of evidence and the social processes involved in developing clinical guidelines have not yet been fully explored. This qualitative study considers the individual, group and external factors that influenced the recommendations made by one guideline development group for the guideline concerning diagnosis and management of macular degeneration within the ophthalmology therapeutic area in the UK. Using direct observation, interviews and document analysis methods, this study explored, over 27-months, how the guideline group proceeded from reviewing the evidence on this condition to drafting guideline recommendations. This research provides a detailed account of how the guideline group – working within an environment that includes influential external stakeholders – interpreted evidence, interacted and functioned as a group, and made consensus decisions on guideline recommendations. The study reveals that the ready availability (and acceptability) of evidence shapes the extent of reliance on expert opinion. In circumstances of low evidence availability, expert opinion is relied upon and factors such as group composition and dynamics, resource availability and external network challenges appear to be particularly important in the guideline development process and in shaping the guideline recommendations. The study is the first to provide an account of the guideline development process in the ophthalmology area as well as adding, more generally, to the empirical literature on the clinical guideline development. The findings suggest that clinical and economic evidence does not easily or smoothly translate into strong recommendations. Rather, guideline development involves the interplay of many factors. An additional contribution of this research is the development of an integrative framework to capture and analyse these factors within the guideline development process.

description: We classify two-dimensional local conformal nets with parity symmetry and central charge less than 1, up to isomorphism. The maximal ones are in a bijective correspondence with the pairs of A-D-E Dynkin diagrams with the difference of their Coxeter numbers equal to 1. In our previous classification of one-dimensional local conformal nets, Dynkin diagrams D_{2n+1} and E_7 do not appear, but now they do appear in this classification of two-dimensional local conformal nets. Such nets are also characterized as two-dimensional local conformal nets with mu-index equal to 1 and central charge less than 1. Our main tool, in addition to our previous classification results for one-dimensional nets, is 2-cohomology vanishing for certain tensor categories related to the Virasoro tensor categories with central charge less than 1.

description: In this paper we report on the herbivore-affected C and N concentrations in the throughfall and altered canopy to soil transfer during a Pine Lappet (Dendrolimus pini L) mass infestation in 60-year-old Scots Pine (Pinus sylvestris L) forests. Our investigations covered a period of 7 months and could show, that herbivore defoliation significantly altered C and N concentrations in the throughfall solution and enhanced organic matter input situation to the forest floor. Compared to the uninfested site mean concentrations of the throughfall solution at the infested site under strong frass activity contained 80% more C and 61% more N. Additionally, C and N inputs were with 131 kg C ha-1 time-1 and 9.6 kg N ha-1 time-1 higher under strong frass activity during 3 months compared to the input at the uninfested site. We assume that outbreaks of phytophagous insects play an important key role in monoculture forest by influencing the nutrient turnover.

description: We present the final sample of 98 detached double white dwarf (WD) binaries found in the Extremely Low Mass (ELM) Survey, a spectroscopic survey targeting <0.3 Msun He-core WDs completed in the Sloan Digital Sky Survey footprint. Over the course of the survey we observed ancillary low mass WD candidates like GD278, which we show is a P=0.19 d double WD binary, as well as candidates that turn out to be field blue straggler/subdwarf A-type stars with luminosities too large to be WDs given their Gaia parallaxes. Here, we define a clean sample of ELM WDs that is complete within our target selection and magnitude range 15

description: The Hispano/Latino population in the United States of America tripled from an estimated population of 14.8 million in 1980 to more than 50.5 million in 2010. Despite their growth and presence throughout the country, the evident underrepresentation of Hispano/Latino artists, staff, board members and visitors in mainstream museums is of concern. This research explores the value and importance of the National Museum of Mexican Art (Chicago, IL) and the National Hispanic Cultural Center (Albuquerque, NM) from the perspective of their staff and the implications of their experiences to the potential establishment of the Smithsonian American Latino Museum.
