ZFIRE : using Hα equivalent widths to investigate the in situ initial mass function at z ~ 2

We use the ZFIRE (http://zfire.swinburne.edu.au) survey to investigate the high-mass slope of the initial mass function (IMF) for a mass-complete (log(10)(M-*/M-circle dot) similar to 9.3) sample of 102 star-forming galaxies at z similar to 2 using their H alpha equivalent widths (H alpha EWs) and rest-frame optical colours. We compare dust-corrected H alpha EW distributions with predictions of star formation histories (SFHs) from PEGASE. 2 and STARBURST99 synthetic stellar population models. We find an excess of high H alpha EWgalaxies that are up to 0.3-0.5 dex above the model-predicted Salpeter IMF locus and the H alpha EW distribution is much broader (10-500 angstrom) than can easily be explained by a simple monotonic SFH with a standard Salpeter-slope IMF. Though this discrepancy is somewhat alleviated when it is assumed that there is no relative attenuation difference between stars and nebular lines, the result is robust against observational biases, and no single IMF (i.e. non-Salpeter slope) can reproduce the data. We show using both spectral stacking and Monte Carlo simulations that starbursts cannot explain the EW distribution. We investigate other physical mechanisms including models with variations in stellar rotation, binary star evolution, metallicity and the IMF upper-mass cut-off. IMF variations and/or highly rotating extreme metal-poor stars (Z similar to 0.1 Z(circle dot)) with binary interactions are the most plausible explanations for our data. If the IMF varies, then the highest H alpha EWs would require very shallow slopes (Gamma > -1.0) with no one slope able to reproduce the data. Thus, the IMF would have to vary stochastically. We conclude that the stellar populations at z greater than or similar to 2 show distinct differences from local populations and there is no simple physical model to explain the large variation in H alpha EWs at z similar to 2.
The Relative Influence of Consumer Innovativeness, Brand Loyalty, and Deal Proneness on New Product Adoption: A Direct Product Experience Study

When consumers are introduced to new products, they often undergo a complex decision making process. Adopting an approach-avoidance conflict framework, this study examines the influence of three consumer dispositions, specifically consumer innovativeness, brand loyalty, and deal proneness on the adoption of an innovative premium consumer product being marketed under a new brand name. A panel of 132 households comprising a total of 493 consumers participated in a one-week trial of the new product/brand during which both pre- and post- test data were collected. Hypotheses were tested using structural equation modeling and multiple-group analyses to assess the moderating effects of demographic characteristics. The pooled results reveal that deal proneness (an avoidance mechanism) has the strongest influence on new product adoption, which contradicted the initial hypothesis of a negative relationship. The next strongest influence on new product adoption is consumer innovativeness (an approach mechanism), in the hypothesized positive direction. Brand loyalty (an avoidance mechanism) has a moderate negative influence as hypothesized. These influences are consistent between older and younger, as well as male and female consumer groups. These findings offer important implications to marketers of new products and provide directions for future research.
Flexible Contract Workers in Inferior Jobs: Reappraising the Evidence

There has been concern that the increase in non-standard or flexible employment contracts witnessed in many OECD economies is evidence of a growth in low-pay, low-quality jobs. In practice, however, it is difficult to evaluate the `quality' of flexible jobs. Previous research has either investigated objective measures of job quality such as wages and training or subjective measures such as job satisfaction. In this paper, we seek to jointly evaluate objective and subjective elements of flexible employment contracts. Specifically we develop and use an index of job quality that incorporates both subjective and objective elements. Analysis of this index demonstrates that flexible jobs are of a lower quality. However, this approach suggests that analysis of, for instance, job satisfaction alone overstates the negative impact of flexible contracts on workers.
Body Configuration in Multiple Somersault High Bar Dismounts

An 11-segment three-dimensional simulation model was used to modify the body configurations of eight gymnasts performing multiple somersault dismounts during the Men’s High Bar competition in the 1988 Seoul Olympic Games. Four layout double somersault performances were modified to change a characteristic backward arch to a straight body position. This modification reduced the somersault rotation by 0.03 to 0.10 somersaults. Four tucked triple somersault performances were modified so that the thigh abduction angle was reduced to zero. This modification resulted in underrotations ranging from 0.01 to 0.34 somersaults depending on the amount of thigh abduction in the original movement. The additional angular momentum needed for successful completion of the modified movements was small in general and in no case greater than 13%.
The Impact of Task Complexity on Iranian EFL Learners' L2 Reading Comprehension

The present study was conducted to compare the effect of dual task instruction with that of single task instruction on reading comprehension. Skehan (1998) argues that the more demanding tasks tap into more attentional resources, the less attention will be available to focus on form. Robinson's (2005) prediction that increasing task complexity along resource–dispersing dimensions will result in worse outcomes matches with Skehan's argument. Sixty intermediate students, majoring in English language and translation studies at the University of Zanjan were selected based on the Nelson English Language Test results. These participants were then randomly divided into three groups: one control group and two experimental groups. The participants in each group read a text, but under different instructions. The participants of the first group were required to read the text and then answer the reading comprehension questions only (single reading comprehension instruction). The participants in the second group were told to read the text and then answer both vocabulary and reading comprehension questions (dual task). The participants of control group received no task instruction. Data analysis results indicated that single task group (reading comprehension task instruction) outperformed the dual task group (both vocabulary and reading comprehension task instruction).
Boundary derivatives of the phases of inner and outer functions and applications

We prove that boundary derivatives of the phases of inner functions exist and are positive almost everywhere, but those of outer functions, on the other hand, have zero mean on the boundary. The concepts and results have definitive applications to the definitions of instantaneous frequency and mono‐components complying with requirements in physics and contemporary study of analytic signals.

Sovereign Credit Risk Analysis for Selected Asian and European Countries

We analyze the nature of sovereign credit risk for selected Asian and European countries through a set of sovereign CDS data for an eighty-year period that includes the episode of the 2008-2009 financial crisis. Our principal component analysis results suggest that there is strong commonality in sovereign credit risk across countries after the crisis. The regression tests show that the commonality is linked to both local and global financial and economic variables. Besides, we also notice intriguing differences in the sovereign credit risk behavior of Asian and European countries. Specifically, we find that some variables, including foreign reserve, global stock market, and volatility risk premium, affect the of Asian and European sovereign credit risks in the opposite direction. Further, we assume that the arrival rates of credit events follow a square-root diffusion from which we build our pricing model. The resulting model is used to decompose credit spreads into risk premium and credit-event components.
Late Weichselian Stratigraphy at Hjelmeland, Southwest Norway

Based on grain-size distributions, fabrics, fossil molluscs, pollen contents, plant macrofossils and radio­ carbon dating, a glacial history is proposed: l) The area was deglaciated during the Bolling or Older Dryas Chronozone. Molluscs indicate the presence of Atlantic water; 2) During the late Allerod or early Younger Dryas Chronozone there was a glacial readvance. A surge mechanism is proposed for this readvance; 3) The glacier front retreated during the early Younger Dryas Chronorone to the fjord-mouth where it remained for several hundreds of years. Atlantic water was replaced by cold polar water. P. Blystad, Arkeologisk museum i Stavanger, Boks 478, N-4001 Stavanger, Norway. ,.
A theorem on the methodology of positive economics

Abstract It has long been recognized that the Milton Friedman’s 1953 essay on economic methodology (or F53, for short) displays open-ended unclarities. For example, the notion of “unrealistic assumption” plays a role of absolutely fundamental importance in his methodological framework, but the term itself was never unambiguously defined in any of the Friedman’s contributions to the economics discipline. As a result, F53 is appealing and liberating because the choice of premises in economic theorizing is not subject to any constraints concerning the degree of realisticness (or unrealisticness) of the assumptions. The question: “Does the methodology of positive economics prevent the overlapping between economics and science fiction? ” comes very naturally, indeed. In this paper, we show the following theorem: the Friedman’s methodology of positive economics does not exclude science fiction. This theorem is a positive statement, and consequently, it does not involve value judgements. However, it throws a wrench on the formulation of economic policy based on surreal models.
Segmentation-Based Ground Points Detection from Mobile Laser Scanning Point Cloud

In most Mobile Laser Scanning (MLS) applications, filtering is a necessary step. In this paper, a segmentation-based filtering method is proposed for MLS point cloud, where a segment rather than an individual point is the basic processing unit. Particularly, the MLS point cloud in some blocks are clustered into segments by a surface growing algorithm, then the object segments are detected and removed. A segment-based filtering method is employed to detect the ground segments. Two MLS point cloud datasets are used to evaluate the proposed method. Experiments indicate that, compared with the classic progressive TIN (Triangulated Irregular Network) densification algorithm, the proposed method is capable of reducing the omission error, the commission error and total error by 3.62%, 7.87% and 5.54% on average, respectively.
Dividend Announcements and Stock Market Reaction

This paper presents "Dividend Announcements and Stock Market Reaction in Kuala Lumpur Stock Exchange. " Using an event study approach, the evidence shows that dividend increase announcements are greeted positively by investors, while there are some evidences suggesting investors react negatively prior to dividend decrease announcements. The observations are then separated into the magnitude of dividend change and income change. This paper also separates the observations into government linked companies (GLCs) and non-GLCs.
CERN-TH-2017-125 Precision Probes of QCD at High Energies

New physics, that is too heavy to be produced directly, can leave measurable imprints on the tails of kinematic distributions at the LHC. We use energetic QCD processes to perform novel measurements of the Standard Model (SM) Effective Field Theory. We show that the dijet invariant mass spectrum, and the inclusive jet transverse momentum spectrum, are sensitive to a dimension 6 operator that modifies the gluon propagator at high energies. The dominant effect is constructive or destructive interference with SM jet production. We compare differential next-to-leading order predictions from POWHEG to public 7 TeV jet data, including scale, PDF, and experimental uncertainties and their respective correlations. We constrain a New Physics (NP) scale of 3.5 TeV with current data. We project the reach of future 13 and 100 TeV measurements, which we estimate to be sensitive to NP scales of 8 and 60 TeV, respectively. As an application, we apply our bounds to constrain heavy vector octet colorons that couple to the QCD current. We project that effective operators will surpass bump hunts, in terms of coloron mass reach, even for sequential couplings. 1 simone.alioli@cern.ch 2 farina.phys@gmail.com 3 duccio.pappadopulo@gmail.com 4 ruderman@nyu.edu 1 ar X iv :1 70 6. 03 06 8v 2 [ he pph ] 2 6 Ju l 2 01 7
Research on Continued Use of Sport-related Social Application: Taking WeRun as an Example

Research on healthcare gadget or application is not new to many of us, yet WeRun's special features have been a reason, and it is completely free of charge. While we take into consideration that WeRun is the most popular application in the world, this study makes a through exploration of how this application could attract loyal members and recruit new members every day. Based on the Theory of Expectation Confirmation, the research combing the variables of emotional pleasure and subjective norm into the expectation-confirmation model of IS continuance (ECM-ISC) to measure the factors that affect the continued use of WeRun by users. A 325 online questionnaire survey had been conducted to this research. The results show that emotional pleasure was positively and significantly associated with users' satisfaction of WeRun and internal influence was positively and significantly associated with users' continuance intention. However, emotional pleasure is not significantly associated with users' continuance intention and external influence has negative influence on user's continuance intention.
Luminex Crossmatch as a Successful Algorithm for Post-Transplant Follow-up in Developing Nations-A Study of 169 Consecutive Samples

Background: Since 2014 Luminex crossmatch (LXM) is being performed regularly in India for post-transplant management of renal allograft recipients. Aim This study was planned to evaluate the possible role of the LXM in the post-transplant setting for the detection and characterization of HLA-specific IgG antibodies and to correlate with allograft biopsy and renalfunction. Methods: A retrospective study was performed on 169 consecutive LXM performed at a single center to investigate suspected allograft dysfunction (n=147) and for monitoring DSA in normally functioning allografts (n=22). A total of 116 biopsies (including 11 repeats) and 40 panel reactive antibody (PRA) screen tests were performed. Results: Donor specific antibodies (DSA) were detected in 81 samples (47.9%): 7 recipients had HLA class I DSA alone, 56 had only HLA class II DSA and 18 recipients had both. First time biopsies were categorized as: negative for rejection (n=30), antibody mediated rejection (n=32), acute cellular rejection (n=23), chronic rejection (n=15) and dual morphology (n=5). LXM was positive in 44/75 biopsies with rejection and transiently raised in 11/30 recipients who showed no evidence of rejection. On the basis of the LXM results biopsywas not performed in 42 recipients who showed improved renal function 15 recipients with non-specific findings on first biopsy. Conclusion: The study suggests that LXM is useful and economically viable algorithm for the detection of antibodies in the post-transplant work up of renal allograft recipients in developing nations.
Life-cycle management of construction projects based on virtual prototyping technology

Life-cycle management (LCM) has been employed in the management of construction projects for many years in order to reduce whole life cost, time, risk and improve the service to owners. However, owing to lack of an effective information sharing platform, the current LCM of construction projects is not effectively used in the construction industry. Based upon the analysis of the information flow of LCM, a virutal prototyping (VP)-based communication and collaboration information platform is proposed. Following this, the platform is customized using DASSAULT sofware. The whole process of implementing the VP-based LCM are also discussed and, from a simple case study, it is demonstrated that the VP-based communication and collaboration information platform is an effective tool to support the LCM of construction projects.
Right ventricular Hemodynamic Alteration after Pulmonary Valve Replacement in Children with Congenital Heart Disease

Introduction:Â Â In patients who underwent surgery to repair Tetralogy of Fallot, right ventricular dilation from pulmonary regurgitation may be result in right ventricular failure, arrhythmias and cardiac arrest. Hence, pulmonary valve replacement may be necessary to reduce right ventricular volume overload. The aim of present study was to assess the effects of pulmonary valve replacement on right ventricular function after repair of Tetralogy of Fallot. Â Â Materials andÂ Â Method:Â Â This retrospective study was carried out between July 2011 and October 2013 on 21 consecutive patients in Chamran Heart Center (Esfahan). The study included 13 male (61.9) and 8 female (38.1). Cardiac magnetic resonance was performed before, 6 and 12 months after pulmonary valve replacement in all patients (Babak Imaging Center, Tehran) with the 1.5 Tesla system. The main reason for surgery at Tetralogy of Fallot repaired time was Tetralogy of Fallot + Pulmonary insufficiency (17 cases) and Tetralogy of Fallot + Pulmonary atresia (4 cases). Right ventricular function was assessed before and after pulmonary valve replacement with Two-dimensional echocardiography and ttest was used to evaluate follow-up data. Â Â Results:Â Â Right ventricular end-diastolic volume, right ventricular end- systolic volume significantly decreased (P value E� 0.05). Right ventricular ejection fraction had a significant increase (P value E� 0.05). Right ventricular mass substantially shrank after pulmonary valve replacement. Moreover, pulmonary regurgitation noticeably decreased in patients. The other hemodynamic parameter such as left ventricular ejection fraction improved but was not significant (P value= 0.79). Conclusion:Â Â Pulmonary valve replacement can successfully restores the impaired hemodynamic function of right ventricle which is caused by direct consequence of volume unloading in patient. Pulmonary valve surgery in children with Tetralogy of Fallot who have moderate to severe pulmonary regurgitation leads to an improvement of right ventricular function. Â
Prevalence of metabolic syndrome using NCEP-ATPIII and ınternational dietetics federation (IDF) definitions: A cross- sectional study in Turkish adults

To estimate the prevalence of metabolic syndrome using international dietetics federation (IDF) versus National cholesterol education program; adult treatment panel III (NCEP-ATPIII) definitions in Turkish adults. A cross-sectional study was conducted on a total of 1531 (male 758 and female 773) Turkish adults, aged between 20 to 64 years. Subjects were randomly selected from the general population of Ankara. The overall prevalence of MetS, as defined by NCEP-ATPIII and IDF was 48.2 and 56.4%, respectively. The agreement between National cholesterol education program (NCEP) and IDF definitions was substantial (kappa: 0.79). The prevalence was increased significantly according to increasing age in women, but was not different by age group in men. The prevalence of MetS in all age groups was higher in women. Hypertriglyceridemia and low High-density lipoprotein cholesterol (HDLC) were the criteria of metabolic syndrome (MetS) with the highest prevalence. According to IDF criteria, the frequency of participants with high fasting plasma glucose (FPG) and Waist circumference (WC) was higher than the participants with adult treatment panel III (ATP III) criteria. The prevalence of the MetS was found to be very high, especially in women. The IDF definition resulted in a higher prevalence of metabolic syndrome than the NCEP-ATPIII in the entire Turkish population. The agreement between the IDF and NCEP definitions for metabolic syndrome was very good. Key words: Metabolic syndrome, NCEP-ATPIII, IDF, adult.

How to model supernovae in simulations of star and galaxy formation

Author(s): Hopkins, PF; Wetzel, A; Keres, D; Faucher-Giguere, CA; Quataert, E; Boylan-Kolchin, M; Murray, N; Hayward, CC; El-Badry, K | Abstract: © 2018 The Author(s). Published by Oxford University Press on behalf of the Royal Astronomical Society. We study the implementation of mechanical feedback from supernovae (SNe) and stellar mass loss in galaxy simulations, within the Feedback In Realistic Environments (FIRE) project. We present the FIRE-2 algorithm for coupling mechanical feedback, which can be applied to any hydrodynamics method (e.g. fixed-grid, moving-mesh, and mesh-less methods), and black hole as well as stellar feedback. This algorithm ensures manifest conservation of mass, energy, and momentum, and avoids imprinting 'preferred directions' on the ejecta. We show that it is critical to incorporate both momentum and thermal energy of mechanical ejecta in a self-consistent manner, accounting for SNe cooling radii when they are not resolved. Using idealized simulations of single SN explosions, we show that the FIRE-2 algorithm, independent of resolution, reproduces converged solutions in both energy and momentum. In contrast, common 'fully thermal' (energy-dump) or 'fully kinetic' (particle-kicking) schemes in the literature depend strongly on resolution: when applied at mass resolution ≳100M⊙, they diverge by orders of magnitude from the converged solution. In galaxy-formation simulations, this divergence leads to orders-of-magnitude differences in galaxy properties, unless those models are adjusted in a resolution-dependent way. We show that all models that individually time-resolve SNe converge to the FIRE-2 solution at sufficiently high resolution (l 100M⊙). However, in both idealized single-SN simulations and cosmological galaxy-formation simulations, the FIRE-2 algorithm converges much faster than other sub-grid models without re-tuning parameters.
