Modal Inversion SW 06 Experiment

Modal dispersion data i.e. mode travel time as a function of frequency have been used in inversion schemes that estimate sediment properties in a range-independent environment. This method has been extended to include range-dependent environment. Simulation studies show that range-dependent sediment properties can be extracted if mode dispersion data are obtained for multiple source/receiver locations [1]. In the Shallow Water 2006 experiment effort was made to collect co-located data sets to perform inversions using both, mode dispersion data and mode eigenvalues. The overlapping data sets will provide a direct means of comparison and evaluation of compressional wave speed profile estimates from mode dispersion data and mode eigenvalues
Religion and education: recent evidence from the United States

While there is evidence to suggest that education is positively related to religious activity, it is possible that education may be endogenous. We re-examine this relationship using the cumulative US General Social Survey (GSS) data file. While we observe a positive correlation between education and attendance at religious services, we find no evidence to support a causal inference. Moreover, while we observe a positive association between education and religious contributions, the possibility of causal connection cannot be dismissed.
Hi & Ha , are new indices in differentiation between Iron deficiency anemia and beta-Thalassaemia trait / A Study in Sulaimani City-Kurdistan / Iraq

Objectives: This study was conducted to compare the validity of newly created indices, Hisham (Hi index), and Hameed (Ha index) with various discrimination indices in differentiating beta-Thalassaemia trait (β-TT ) from iron deficiency anemia (IDA) by calculating their sensitivity, specificity and Youden's index. Methods: in total 600 adult patients with microcytic anemia were involved. New hematological indices (Hi) = (MCH×RDW)/RBC & (Ha) = (MCH×Hct×RDW)/(RBC×Hb) were created, and a total of fifteen discrimination indices; RBCs, RDW, Mentzer index (MI), Shine & Lai index (S&L), England &Fraser index (E&F), Srivastava index (S), Green & King index (G&K), RBC distribution width index (RDWI), Ricerca index (R), Keikhaei index (KI), Telmissani et al index (TI), Ehsani et al index (EI), Sirdah et al index (SI), (Hi) & (Ha) were used to differentiate between these two conditions. Youden’s index of each discrimination index was calculated. Results: All fifteen discrimination indices didn’t have the sensitivity and specificity of 100%. The Ha & Hi indices showed the most reliable discrimination indices in differentiation between β-TT and IDA. Conclusion: Youden's index of Ha & Hi was the highest and most reliable in differentiating β-TT from IDA in the adult patient.
Galactosylated poly(ethylene glycol)-b-poly (l-lactide-co-β-malic acid) block copolymer micelles for targeted drug delivery: preparation and in vitro characterization

Biodegradable galactosylated methoxy poly(ethylene glycol)/poly(l-lactide-co-β-malic acid) (Gal-PEG-b-PLMA) block copolymer micelles were successfully prepared by a solvent diffusion method, and could efficiently encapsulate doxorubicin. The Gal-PEG-b-PLMA micelles before and after doxorubicin loading were characterized by size, morphology, in vitro drug release, and in vitro cytotoxicity in HepG2 cells. Transmission electron microscopy and dynamic light scattering results showed that the empty and doxorubicin-loaded micelles were approximately spherical in shape and had mean sizes of about 72 nm and 85 nm, respectively. In vitro release behavior of doxorubicin from the micelles was pH-dependent, with obviously faster release rates at mildly acidic pH 4.5 and 5.5 compared with physiologic pH 7.4. Methylthiazoletetrazolium assay and flow cytometric analysis indicated that the doxorubicin-loaded galactosylated micelles exhibited a greater growth-inhibitory effect on HepG2 cells than the nongalactosylated doxorubicin-loaded micelles, and induced S phase cell cycle arrest. Confocal laser scanning microscope observations revealed that the galactosylated micelles could be efficiently internalized by HepG2 cells through receptor-mediated endocytosis. The results suggest that Gal-PEG-b-PLMA copolymer micelles are a promising carrier system for targeted drug delivery in cancer therapy.
2-D Analytical Drain Current Model of Double-Gate Heterojunction TFETs With a SiO2/HfO2 Stacked Gate-Oxide Structure

A continuous 2-D analytical drain current model of double-gate (DG) heterojunction tunnel field-effect transistors (HJTFETs) with a SiO2/HfO2 stacked gate-oxide structures has been presented in this paper. The surface potential model has been developed by considering the effect of accumulation/inversion charges and depletion region at source/channel and drain/channel junctions. The electric field-dependent band-to-band tunneling generation rate has been derived from the surface potential model. The tangent line approximation method has been used to calculate the drain current of DG HJTFETs. The developed model is valid for all regions (subthreshold to strong accumulation/inversion region) of operation. The model has been developed for Si/Ge hetero and Si homojunction-based tunnel field-effect transistor devices. The model is also applicable for other structures such as III–V materials-based InAs/GaSb DG HJTFET and silicon-on-insulator-based HJTFET. The analytical model results are validated by 2-D ATLAS simulation data.
Clinical value of glioma-associated oncogene homolog 1 as a prognostic marker in cancer : a meta-analysis

Aberrant activation of the transcription factor glioma-associated oncogene homolog 1 (GLI1), a central effector of the Hedgehog (HH) pathway, is associated with human malignancies. Emerging evidence has shown that overexpressed GLI1 is significantly correlated with clinicopathologic features and poor prognosis in patients with cancer. To evaluate the clinical value of GLI1 as a prognostic marker in human cancers, this meta-analysis collected all relevant articles and explored the association of GLI1 expression levels with prognosis in patients with carcinoma. Literature collection was conducted by searching electronic databases PubMed, Medline, EMBASE, Web of Science, Ovid and Cochrane library (up to July 10, 2015). Pooled hazard ratios (HRs) with corresponding 95% confidence intervals (CIs) were calculated to estimate the strength of the link between GLI1 and clinical prognosis by STATA 12.0 software. 21 eligible studies with a total of 2381 patients were matched to our inclusion criteria. The result showed that overexpression of GLI1 could predict poor overall survival (OS) and disease-free survival (DFS) in patients with cancer, with HR of 2.07 (95% CI 1.83-2.35), HR of 1.81 (95% CI 1.53-2.16), respectively. Residence region (Asia and Europe), cancer type (nervous, digestive and respiratory system carcinoma), measurement methods (IHC and PCR) and methods of analysis (univariate and multivariate analyses), did not alter the predictive value of GLI1 on poor OS among the investigated cancers. This meta-analysis demonstrated that GLI1 may be used as a prognostic marker to predict poor survival of patients with cancer.
The Portland Hills Fault: An Earthquake Generator or Just Another Old Fault?

Several lines of indirect evidence and preliminary interpretations of recently collected seismic reflection data have led to the conclusion that the Portland Hills fault at the eastern base of the Portland Hills appears to be capable of generating large-magnitude earthquakes. Although no historical earthquake can be associated with the Portland Hills fault, small-magnitude seismicity in the past 20 years in the vicinity of the Portland Hills fault zone, which includes the Oatfield and East Bank faults, suggests that one or all of these structures may be seismogenic. The Portland Hills fault may be 40–60 km long, probably dips to the southwest beneath the Portland Hills, and may slip in a reverseoblique sense. Limited observations suggest that, on average, the intervals between large earthquakes are a few thousand to more than 10,000 years. Given its location in the midst of the Portland metropolitan area, rupture of the Portland Hills fault resulting in a large earthquake could be devastating. Future studies are required to characterize the earthquake potential of the fault in a more definitive manner and to provide an improved basis for predicting the hazards that would result from such a large earthquake.
Cryptic Diversity in Common Mustached Bats Pteronotus cf. parnellii (Mormoopidae) in French Guiana and Brazilian Amapa

The common mustached bat (Pteronotus parnellii) is a mormoopid bat living in caves in lowland rainforests throughout the north and eastern Neotropics, including several Caribbean islands. Recent studies have shown that this taxon is certainly a composite of several cryptic species, especially in the western part of the Guianan Shield, where molecular reconstructions and bioacoustics point to the presence of at least two cryptic species that may not be related to genuine P. parnellii, native to Jamaica. We examined here over 200 bioacoustically identified individuals to show that two phonic types live in sympatry in French Guiana with no overlap in frequencies of echolocation calls. Morphological variation in some skull characters showed consistent and significant differences between the two phonic types, whereas external measurements alone were unable to discriminate between groups. Two mitochondrial markers analyzed in a selection of each of these phonic types were further used to evidence that they represent two genetically discrete groups, and to assign them to the existing molecular clades described elsewhere. Molecular comparisons with reference specimens sampled near the type localities of P. parnellii and P. rubiginosus further suggest that the 53 kHz phonic type found in French Guiana and Amapa (Brazil) should be assigned to the later species, while the 59 kHz phonic type represents an undescribed species.
The role of socioscientific issues in biology teaching: from the perspective of teachers

ABSTRACT Previous research has documented that students who engage with socioscientific issues can acquire some of the complex competences and skills typically related to scientific literacy. But an emerging field of research on science teachers’ understanding and use of socioscientific issues, has documented that a range of challenges hinders the uptake of socioscientific issues. In this study, we investigated the interpretation and implementation of socioscientific issues among Danish biology teachers. We conducted five in-depth group interviews and validated the emergent themes from the teachers’ talk-in-interaction by distributing a questionnaire. Our findings suggest that the participating teachers generally harbour a content-centred interpretation of socioscientific issues which manifests itself in at least three separate ways. First, the teachers generally use socioscientific issues as a vehicle to teach factual biological content. Second, the teachers emphasised mastery of factual content in their assessment. Third, the teachers tended to reduce socioscientific issues to specific biological contents in a way may preclude students from engaging with the real socioscientific issue. Our findings are particularly significant for science educators, policy-makers and curriculum designers, as we argue that key aspects of this content-centred interpretation may be a coping strategy used to navigate a divided curriculum.
High-order overset grid method for detecting particle impaction on a cylinder in a cross flow

An overset grid method was developed to investigate the interaction between a particle-laden flow and a circular cylinder. The method is implemented in the Pencil Code, a high-order finite-difference code for compressible flow simulation. High-order summation-by-parts operators were used at the cylinder boundary, and both bi-linear Lagrangian and bi-quadratic spline interpolation were used to communicate between the Cartesian background grid and the body-conformal cylindrical grid. The performance of the overset grid method was assessed to benchmark cases of steady and unsteady flows past a cylinder. Results show high-order accuracy and good agreement to the literature. Particle-laden flow simulations were performed, with inertial point particles impacting on a cylinder. The simulations reproduced results from the literature at a significantly reduced cost. Further, an investigation into blockage effects on particle impaction revealing that the previously published DNS data is less accurate than assumed for particles with very small Stokes numbers.
Estresse, qualidade de vida e estressores ocupacionais de policiais: sintomas mais frequentes

Quality of life, occupational stress, and its causes were evaluated in 1,837 members of the police force in the State of Mato Grosso. The sample ranged from 19 to 65 years of age, with 77% of participants male and 23% female. It was comprised of military police (n=1,017), military fire brigade (n=108), civil police (n=454), forensic specialists (n=68), and administrative staff (n=190). It was found that 52% exhibited symptoms of stress. Quality of life was found to be lacking, primarily regarding health. The data show a significant association between high stress levels and poor quality of life. The study reveals that there is a need for institutional actions to stimulate the acquisition of stress coping strategies that can promote a better quality of life among public security servants in the state.

A marriage of manifolds and algebra : the mathematical work of Peter Landweber

It is no accident that Peter Landweber’s career closely matches the striking unification of algebra and topology provided by the theory of bordism of manifolds, especially complex bordism: his work has been at the heart of that interaction. Here I will briefly describe some of Landweber’s main contributions to this story. The starting point was Thom’s work [59], from 1954, in which he used transversality to identify bordism classes of closed smooth nmanifolds with what we today call the nth homotopy group of the Thom spectrum MO (though of course it was in part an attempt to express Thom’s arguments conveniently that later led to the concept of a spectrum) and then computed the homology of this (by the Thom isomorphism) and the homotopy (and actually the homotopy type). The result was that any mod 2 cohomology class was carried by a “singular manifold,” the image of the fundamental class of a smooth closed manifold under a map; and the bordism ring is a polynomial algebra over Z/2Z with one generator in each positive degree not one less than a power of 2. Thom also considered the oriented bordism ring Ω∗ = π∗(MSO). This was followed in 1960 by the use of the newly minted Adams spectral sequence [1], independently by Milnor [44] and by Novikov [51] to make the analogous computation of the complex bordism ring Ω ∗ = π∗(MU). The result was a polynomial algebra over Z with one

Market value, book value and earnings: is bank efficiency a missing link?

Purpose - This paper examines whether earnings and its components are relevant and sufficient to bridge the gap between banks' market and book values, and also considers if bank efficiency is “value relevant” for banks valuation. Design/methodology/approach - This paper follows the value relevance literature methodology which tests for the difference between book and market values using a variety of indicators including net income and its components as well as bank efficiency (derived using DEA) and risk indicators. The regression models are estimated using OLS, random and fixed effects approaches for a sample of listed Jordanian banks between 1993 and 2004. Findings - The main findings of this paper are twofold. First, it is found that earnings (and its components) are value relevant and explain the gap between market and book values. Secondly, cost efficiency, as an economic performance measure, provides incremental information, not contained directly in banks financial statements, to the market. Overall it is found that the components of net income are more important than aggregate net income in explaining bank value. Furthermore, bank operational efficiency adds incremental information in explaining the gap between market and book value. These results support the view that stock prices aggregate signals received by the market as well as from firm's accounting systems. Practical implications - The study shows that bank efficiency indicators (along with more traditional accounting measures) help explain market values. Originality/value - This is one of only a limited number of studies that link bank efficiency to market valuation. It is the first, we believe, to do this for banks operating in an emerging economy.

Identification of 72 phytoplankton species by radial basis function neural network analysis of flow cytometric data

Radial basis function artificial neural networks (ANNs) were trained to discriminate between phytoplankton species based on 7 flow cytometric parameters measured on axenic cultures. Comparison was made between the performance of networks restricted to using radially-symmetric basis functions and networks using more general arbitrarily oriented ellipso~dal basis functions, with the latter proving significantly superior in performance. ANNs trained on 62, 54 and 72 taxa identified them with respectively 77, 73 and 70% overall success. As well as high success in identification, high confidence of correct identification was also achieved. Misidentifications resulted from overlap of character distributions. Improved overall identification success can be achieved by grouping together species with similar character distributions. This can be done within genera or based on groupings indicated in dendrograms constructed for the data on all species. When an ANN trained on 1 data set was tested with data on cells grown under different light conditions, overall successful identification was low (<20%), but when an ANN was trained on a combined data set identification success was high (>? 0%). Clearly it is essential to include data on cells covering the whole spectrum of biological variatlon. Ways of obtaining data for training ANNs to identify phytoplankton from field samples are discussed.
OSTEOPHYTES AND THE OSTEOARTHRITIC FEMORAL HEAD *

The study describes the topography, morphology and growth of osteophytes in forty femoral heads removed from patients presenting with advanced osteoarthritis of the hip. In addition to standard histological techniques, radiography of serial bone slices and in vivo bone labeffing with tetracycline and 32P were used. The pattern of major osteophyte formation appeared to be influenced by the direction, degree and rate of displacement of the femoral head in relation to the acetabulum ; four principal patterns of growth were noted. Osteophytes form part of extensive osteogenic processes that involve bone structure in the osteoarthritic joint.
A TWO-PARAMETER MODEL FOR THE INFRARED/SUBMILLIMETER/RADIO SPECTRAL ENERGY DISTRIBUTIONS OF GALAXIES AND ACTIVE GALACTIC NUCLEI

A two-parameter semi-empirical model is presented for the spectral energy distributions of galaxies with contributions to their infrared–submillimeter–radio emission from both star formation and accretion disk-powered activity. This model builds upon a previous one-parameter family of models for star-forming galaxies, and includes an update to the mid-infrared emission using an average template obtained from Spitzer Space Telescope observations of normal galaxies. Star-forming/active galactic nucleus (AGN) diagnostics based on polycyclic aromatic hydrocarbon equivalent widths and broadband infrared colors are presented, and example mid-infrared AGN fractional contributions are estimated from model fits to the Great Observatories All-Sky LIRG Survey sample of nearby U/LIRGS and the Five mJy Unbiased Spitzer Extragalactic Survey sample of 24 μm selected sources at redshifts 0 ≲ z ≲ 4.
