Supplement: "Localization and broadband follow-up of the gravitational-wave transient GW150914" (2016, ApJL, 826, L13)

This Supplement provides supporting material for Abbott et al. (2016a). We briefly summarize past electromagnetic (EM) follow-up efforts as well as the organization and policy of the current EM follow-up program. We compare the four probability sky maps produced for the gravitational-wave transient GW150914, and provide additional details of the EM follow-up observations that were performed in the different bands

All-sky search for long-duration gravitational wave transients with initial LIGO

We present the results of a search for long-duration gravitational wave transients in two sets of data collected by the LIGO Hanford and LIGO Livingston detectors between November 5, 2005 and September 30, 2007, and July 7, 2009 and October 20, 2010, with a total observational time of 283.0 days and 132.9 days, respectively. The search targets gravitational wave transients of duration 10–500 s in a frequency band of 40–1000 Hz, with minimal assumptions about the signal waveform, polarization, source direction, or time of occurrence. All candidate triggers were consistent with the expected background; as a result we set 90% confidence upper limits on the rate of long-duration gravitational wave transients for different types of gravitational wave signals. For signals from black hole accretion disk instabilities, we set upper limits on the source rate density between 3.4×10−5 and 9.4×10−4  Mpc−3 yr−1 at 90% confidence. These are the first results from an all-sky search for unmodeled long-duration transient gravitational waves

Evaluation of serum enzyme activities as predictors of passive transfer status in lambs

Objective\u2014To determine the associations between serum IgG concentration and serum activities of γ-glutamyltransferase (GGT), alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, and pseudocholinesterase for the potential use of these serum enzymes as predictors of passive transfer status in neonatal lambs. Design\u2014Prospective observational study. Animals\u201447 Sardinian lambs from birth to 2 days old. Procedure\u2014Serum enzyme activities were measured by use of commercially available kits and a clinical biochemical analyzer. Serum IgG concentration was determined by single radial immunodiffusion. Associations between serum IgG concentration and the activity of each serum enzyme were established by use of regression analysis. Results\u2014A significant correlation was detected between serum IgG concentration and serum GGT activity in 1- and 2-day-old lambs. Minimal correlations were detected between serum IgG concentration and serum alkaline phosphatase activity in 1-day-old lambs and serum pseudocholinesterase activity in 1- and 2-day-old lambs. No significant associations were detected between serum IgG concentration and serum activities of aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase. A multiple linear regression model was accurate for the estimation of the natural logarithm of serum IgG concentration as a function of the natural logarithm of serum GGT activity and of the age of lambs at the time of sampling (adjusted R2 = 0.89). This model was then used to calculate the serum GGT activity equivalent to various serum IgG concentrations for 1- and 2-day-old lambs. Conclusions and Clinical Relevance\u2014Results suggested that passive transfer status in neonatal lambs can be successfully predicted by measurement of serum GGT activity but not by measurement of the other enzymes teste

Bacterial Succession within an Ephemeral Hypereutrophic Mojave Desert Playa Lake

Abstract Ephemerally wet playas are conspicuous features of arid landscapes worldwide; however, they have not been well studied as habitats for microorganisms. We tracked the geochemistry and microbial community in Silver Lake playa, California, over one flooding/desiccation cycle following the unusually wet winter of 2004–2005. Over the course of the study, total dissolved solids increased by ∽10-fold and pH increased by nearly one unit. As the lake contracted and temperatures increased over the summer, a moderately dense planktonic population of ∽1 × 106 cells ml−1 of culturable heterotrophs was replaced by a dense population of more than 1 × 109 cells ml−1, which appears to be the highest concentration of culturable planktonic heterotrophs reported in any natural aquatic ecosystem. This correlated with a dramatic depletion of nitrate as well as changes in the microbial community, as assessed by small subunit ribosomal RNA gene sequencing of bacterial isolates and uncultivated clones. Isolates from the early-phase flooded playa were primarily Actinobacteria, Firmicutes, and Bacteroidetes, yet clone libraries were dominated by Betaproteobacteria and yet uncultivated Actinobacteria. Isolates from the late-flooded phase ecosystem were predominantly Proteobacteria, particularly alkalitolerant isolates of Rhodobaca, Porphyrobacter, Hydrogenophaga, Alishwenella, and relatives of Thauera; however, clone libraries were composed almost entirely of Synechococcus (Cyanobacteria). A sample taken after the playa surface was completely desiccated contained diverse culturable Actinobacteria typically isolated from soils. In total, 205 isolates and 166 clones represented 82 and 44 species-level groups, respectively, including a wide diversity of Proteobacteria, Bacteroidetes, Actinobacteria, Firmicutes, Gemmatimonadetes, Acidobacteria, and Cyanobacteria

Use of LIDAR in landslide investigations: A review

This paper presents a short history of the appraisal of laser scanner technologies in geosciences used for imaging relief by high-resolution digital elevation models (HRDEMs) or 3D models. A general overview of light detection and ranging (LIDAR) techniques applied to landslides is given, followed by a review of different applications of LIDAR for landslide, rockfall and debris-flow. These applications are classified as: (1) Detection and characterization of mass movements; (2) Hazard assessment and susceptibility mapping; (3) Modelling; (4) Monitoring. This review emphasizes how LIDARderived HRDEMs can be used to investigate any type of landslides. It is clear that such HRDEMs are not yet a common tool for landslides investigations, but this technique has opened new domains of applications that still have to be developed

Avaliação da profundidade do palato e das dimensões do arco dentário superior em indivíduos com má oclusão e diferentes tipos faciais Evaluation of palatine depth and dimensions of the upper dental arch in patients with malocclusion and different facial types

OBJETIVO: o deste estudo foi avaliar a profundidade do palato e as dimensões do arco dentário superior de indivíduos com má oclusão e diferentes tipos faciais. METODOLOGIA: a amostra empregada neste estudo foi constituída por telerradiografias em norma lateral e modelos de estudo de 135 pacientes com más oclusões de Classe I (n = 45), Classe II (n = 45) e Classe III (n = 45) de Angle, sendo 67 do gênero feminino e 68 do gênero masculino, com faixa etária entre 12 e 21 anos de idade, divididos igualmente em três grupos conforme o tipo facial apresentado: braquifacial, mesofacial e dolicofacial. RESULTADOS E CONCLUSÕES: os resultados obtidos demonstraram que, quanto ao tipo facial, houve diferença estatisticamente significante apenas para a medida da profundidade do palato, sendo que os indivíduos braquifaciais apresentaram palato com menor profundidade (média = 18,18mm), quando comparados aos indivíduos dolicofaciais (média = 19,52mm). Quanto ao dimorfismo sexual, pudemos verificar que os indivíduos do gênero masculino apresentaram médias da distância intermolares superiores (51,36mm) e da profundidade do palato (19,61mm) aumentadas, de forma significante, em relação às médias obtidas para o gênero feminino (50,15mm e 18,37mm para as medidas da distância intermolares e da profundidade do palato, respectivamente). Avaliando o tipo de má oclusão, pudemos constatar que houve diferença estatisticamente significante apenas para a medida do comprimento do arco, sendo que indivíduos com má oclusão de Classe II apresentaram arcos dentários superiores com maior comprimento ântero-posterior (média = 31,23mm) que indivíduos com má oclusão de Classe III (média = 29,64mm). Entretanto, a média da medida comprimento do arco encontrada para o grupo Classe I (30,52mm) não apresentou diferença estatisticamente significante quando comparada às médias obtidas para os grupos Classe II e Classe III.<br>AIM: The aim of this study was to evaluate palatine depth and dimensions of the upper dental arch in patients with malocclusion and different facial types. METHODS: The sample was constituted of profile cephalograms and dental casts of 135 individuals, 67 females and 68 males, with age between 12 to 21 years and malocclusions: Class I (n = 45), Class II (n = 45) and Class III (n = 45), Angle. The sample was divided in three groups, according to the facial type: brachyfacial (n = 45), mesofacial (n = 45) and dolichofacial (n = 45). The transversal dimensions (intercuspids and inter-first molars distances) and upper dental arch length were obtained with auxiliary of digital caliper. In order, to obtain palatine depth measurement was used a special equipment developed and adapted to the digital caliper. RESULTS AND CONCLUSION: Based on our results, we concluded that: (1) no statistically significant differences between these measurements were found considering the facial types, except for the palatine depth, that was smaller in brachyfacial group (18.18mm) than dolichofacial group (19.52mm); (2) according to sex, only two variables, the depth palatine and inter-first molar distance, demonstrated statistically significant differences, that appeared to be bigger in males than females; (3) according to the malocclusion, statistically significant differences between these measurements were found only to the upper dental arch length, that was bigger in Class II group (31.23mm) than Class III group (29.64mm)
