description: We investigate primordial magnetogenesis and the evolution of the electromagnetic field through a quantum bounce, in a model that starts in the far past from a contracting phase where only dust is present and the electromagnetic field is in the adiabatic quantum vacuum state. By including a coupling between curvature and electromagnetism of the form $RF_{μν}F^{μν}$, we find acceptable magnetic field seeds within the current observational constraints at 1 mega-parsec (Mpc), and that the magnetic power spectrum evolves as a power-law with spectral index $n_B=6$. It is also shown that the electromagnetic backreaction is not an issue in the model under scrutiny.

description: Using the lag-luminosity relation and various BATSE catalogs we create a large catalog of burst redshifts, peak luminosities and emitted energies. These catalogs permit us to evaluate the lag-luminosity relation, and to study the burst energy distribution. We find that this distribution can be described as a power law with an index of alpha=1.76 +/- 0.05 (95% confidence), close to the alpha=2 predicted by the original quasi-universal jet model.

description: We discovered a hysteresis in a microwave-driven low-pressure argon plasma during gas pressure change across the transition region between $α$ and $γ$ discharge modes. The hysteresis is manifested in that the critical pressure of mode transition depends on the direction of pressure change. As a corollary, the plasma would attain different discharge properties under the same operating parameters (pressure, power, and gas composition), suggesting a bi-stability or existence of memory effect. Analysis of the rotational and vibrational temperatures measured from the OH (A-X) line emissions shows that the hysteresis is mainly due to the fast gas heating in the $γ$-mode leading to a smaller neutral density than that of the $α$-mode. When increasing the gas pressure, the $γ$-mode discharge maintains a relatively higher temperature and lower neutral density, and thus, it requires a higher operating pressure to reach the $α$-mode. On the other hand, decreasing the pressure while maintaining $α$-mode, the transition to $γ$-mode occurs at a lower pressure than the former case due to a relatively higher neutral density of $α$-mode discharge. This interpretation is supported by the fact that the hysteresis disappears when the plasma properties are presented with respect to the neutral gas density instead of pressure.
Search for events with a pair of displaced vertices from long-lived neutral particles decaying into hadronic jets in the ATLAS muon spectrometer in pp collisions at $\sqrt{s}=13$ TeV

description: A search for events with two displaced vertices from long-lived particles (LLP) pairs using data collected by the ATLAS detector at the LHC is presented. This analysis uses 139~fb$^{-1}$ of proton-proton collision data at $\sqrt{s}=13$ TeV recorded in 2015-2018. The search employs techniques for reconstructing vertices of LLPs decaying to jets in the muon spectrometer displaced between 3 m and 14 m with respect to the primary interaction vertex. The observed numbers of events are consistent with the expected background and limits for several benchmark signals are determined. For the Higgs boson with a mass of 125 GeV, the paper reports the first exclusion limits for branching fractions into neutral long-lived particles below 0.1%, while branching fractions above 10% are excluded at 95% confidence level for LLP proper lifetimes ranging from 4 cm to 72.4 m. In addition, the paper present the first results for the decay of LLPs into into $t\bar{t}$ in the ATLAS muon spectrometer.

description: Adhoc wireless sensor network is an architecture of connected nodes, each node has its main elements such as sensors, computation and communications capabilities. Adhoc WSNs restrained energy sources result in a shorter lifetime of the sensor network and inefficient topology. In this paper, a new approach for saving and energy controlling is introduced using quality of service, the main reason is to reduce the nodes energy through discovering the best optimum route that meets quality of service requirements; quality of service technique is used to find the optimum methodology for nodes packets transmission and energy consumption.

description: The {\it Transiting Exoplanet Survey Satellite} (TESS) searches for planets transiting bright and nearby stars using high-cadence, large-scale photometric observations. Full Frame Images provided by the TESS mission include large number of serendipitously observed main-belt asteroids. Due to the cadence of the published Full Frame Images we are sensitive to periods as long as of order tens of days, a region of phase space that is generally not accessible through traditional observing. This work represents a much less biased measurement of the period distribution in this period range. We have derived rotation periods for 300~main-belt asteroids and have partial lightcurves for a further 7277 asteroids, including 43 with periods $P > 100$ h; this large number of slow rotators is predicted by theory. Of these slow rotators we find none requiring significant internal strength to resist rotational reshaping. We find our derived rotation periods to be in excellent agreement with results in the Lightcurve Database for the 55~targets that overlap. Over the nominal two-year lifetime of the mission, we expect the detection of around 85,000 unique asteroids with rotation period solutions for around 6000 asteroids. We project that the systematic analysis of the entire TESS data set will increase the number of known slow-rotating asteroids (period > 100~h) by a factor of 10. Comparing our new period determinations with previous measurements in the literature, we find that the rotation period of asteroid (2320) Blarney has decreased by at least 20\% over the past decade, potentially due to surface activity or subcatastrophic collisions.

description: A review of tools and methods to calculate electrostatic potentials and fields inside high-purity germanium detectors in various configurations is given. The methods are illustrated concretely with a new educational program named GeFiCa - Germanium detector Field Calculator. Demonstrated in GeFiCa are generic numerical calculations based on the successive over-relaxation method as well as analytic ones whenever simplification is possible due to highly symmetric detector geometries. GeFiCa is written in C++, and provided as an extension to the CERN ROOT libraries widely used in the particle physics community. Calculation codes for individual detectors, provided as ROOT macros and python scripts, are distributed along with the GeFiCa core library, serving as both examples showing the usage of GeFiCa and starting points for customized calculations. They can be run without compilation in a ROOT interactive session or directly from a Linux shell. The numerical results are saved in a ROOT tree, making full use of the I/O optimization and plotting functionalities in ROOT. The speed and precision of the calculation are comparable to other commonly used packages, which qualifies GeFiCa as a scientific research tool. However, the main focus of GeFiCa is to clearly explain and demonstrate the analytic and numeric methods to solve Poisson's equation, practical coding considerations and visualization methods, with intensive documentation and example macros. It serves as a one-stop resource for people who want to understand the operating mechanism of such a package under the hood.

With future supernova surveys such as SNAP, large numbers of core collapse supernovae will be discovered, a small fraction of which will be multiply imaged. Measurements of the image separation, flux-ratio, time-delay and lensing foreground galaxy for these systems will provide tight constraints on the slope of galactic halos as well as providing complementary and independent information to other cosmological tests with respect to the Hubble parameter.

description: A radiation hard Si detector is used in the new CMS tracker detector at HL-LHC. It has been observed that n-MCz and n-Fz Si as a material can be used for the Si micro strip detector. The detector design for this material should be simulated and optimized to get high CCE. In order to understand the charge collection behavior of the n-MCz/n-FzSi detector, it is required to simulate and compare the radiation damage effects in the mixed irradiated n-MCz Si and neutron irradiated n-FzSi micro strip detector equipped with metal overhang and multiple guard rings. In this paper, we have done analysis and optimization of the radiation hard n-MCz Si/n-Fz Si strip detector design for the HL-LHC experiment in order to get high CCE.

description: Previous research on Lorentz invariance violation in photons from gamma-ray bursts (GRBs) suggested a scenario where multi-GeV photons could be emitted before lower-energy photons at the GRB source frame. This implies the existence of a new preburst phase in addition to the traditionally identified prompt and afterglow stages observed in earlier studies. In this study, we present direct evidence for this novel preburst phase in gamma-ray bursts based on recent observations of GRB 221009A. Our analysis leverages data from the Fermi Gamma-ray Burst Monitor (GBM) and Large Area Telescope (LAT) detectors of the Fermi Gamma-ray Space Telescope (FGST), as well as data from the KM2A detector of the Large High Altitude Air-shower Observatory (LHAASO).

description: Voluntary approaches have become a popular in the U.S. to enhance the efficacy and scope of existing regulations and to reduce emissions in sectors or for pollutants where formal environmental regulation is lacking. In this paper, we examine the effectiveness of a particular EPA voluntary program for the metal finishing industry, the Strategic Goals Program (SGP). The Strategic Goals Program is a good candidate for evaluation because it had a credible regulatory threat at the time the program was implemented, we can measure both baseline emissions and progress towards explicit environmental goals, and we have data for participants and non-participants. We look at the decision to participate in the SGP and also try to determine what effect, if any, this program has had on the pollution profile of facilities. In addition, we examine whether the voluntary program had any discernible impact on toxicity-weighted emissions. Finally, we explore the possibility that we have a bimodal distribution in the sample caused by the different motivations of facilities to join a voluntary program. A number of factors influence a firm’s decision to participate in SGP, including trade group membership. However, we do not find robust evidence that SGP participation has had a significant impact on emission reductions. This result continues to hold when we adjust emissions to account for toxicity. Our measure of the threat of regulation is correlated with emission reductions for both participants and non-participants.

New Research Suggests that Emissions Reductions May Be a Risky and Very Expensive Way to Avoid Dangerous Global Climate Changes

description: Proponents of greenhouse gas emissions reductions have long assumed that such reductions are the best approach to global climate change control and sometimes argued that they are the least risky approach. It is now generally understood that to be effective such reductions would have to involve most of the world and be very extensive and rapidly implemented. This paper examines the question of whether it is feasible to use only this approach to control dangerous global climate changes, the most critical of the climate change control objectives. I show that in one of two critical cases analyzed recent papers provide evidence that such an approach is not a feasible single approach to avoiding the dangerous climate changes predicted by a very prominent group of US climate change researchers. In the other case using a widely accepted international standard I show that such an approach appears to be very risky and much more expensive than previously thought. These conclusions further reinforce previous research that emissions reductions alone do not appear to be an effective and efficient single strategy for climate change control. So although emissions reductions can play a useful role in climate change control, other approaches would appear to be needed if dangerous climate changes are to be avoided. This conclusion suggests that the current proposals in a number of Western European countries and the United States to use emissions reductions as the sole means to control global warming may be doomed to failure in terms of avoiding such dangerous changes. An alternative approach is briefly discussed that would be more effective and efficient, and could avoid the perilous risks and high costs inherent in an emissions reduction only approach.
Multimodality and young childrens' meaning making
Creators: name: Obadia, Nicole
Publisher: name: The University of British Columbia
Year: 2014

description: This paper explores the ways in which children make meaning through literacy experiences in their multimodal environments. It focuses on young children of kindergarten age. This paper summarizes recent research on multimodal pedagogy and explores the research of prominent researches in the field of emergent literacy (Marie Clay, Elizabeth Sulzby and Anne Dyson). The work of these researchers suggests that children draw from their social resources to make meaning of written language. Further, children's writing development involves talking, drawing and the use of a variety of sign symbols to convey meaning. The paper concludes with a kindergarten unit on "Garbage" that highlights multimodal learning experiences and the ways in which multimodal activities support children's writing development.
Blasts from the Past: Supernova Shock Breakouts among X-Ray Transients in the XMM-Newton Archive

Publisher: name: arXiv
Year: 2020
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: The first electromagnetic signal from a supernova (SN) is released when the shock crosses the progenitor surface. This shock breakout (SBO) emission provides constraints on progenitor and explosion properties. Observationally, SBOs appear as minute to hour-long extragalactic X-ray transients. They are challenging to detect and only one SBO has been observed to date. Here, we search the XMM-Newton archive and find twelve new SN SBO candidates. We identify host galaxies to nine of these at estimated redshifts of 0.1-1. The SBO candidates have energies of ${\sim}10^{46}$ erg, timescales of 30-3000 s, and temperatures of 0.1-1 keV. They are all consistent with being SN SBOs, but some may be misidentified Galactic foreground sources or other extragalactic objects. SBOs from blue supergiants agree well with most of the candidates. However, a few could be SBOs from Wolf-Rayet stars surrounded by dense circumstellar media, whereas two are more naturally explained as SBOs from red supergiants. The observations tentatively support non-spherical SBOs and are in agreement with asymmetries predicted by recent three-dimensional SN explosion simulations. eROSITA may detect ${\sim}$2 SBOs per year, which could be detected in live analyses and promptly followed up.
description: 31 pages, 1 figure, 7 tables, 12 SN SBO candidates. Accepted for publication in ApJ. Updated to match the accepted version. We have made minor clarifications and added a comment on the recent preprint by Novara et al. (2020; arXiv:2004.10665), which reports an independent discovery and analysis of one of the SBO candidates. Their and our results and interpretations agree very well with each other

description: The Pollution Abatement Costs and Expenditures (PACE) survey is the most comprehensive source of information on U.S. manufacturing’s capital expenditures and operating costs associated with pollution abatement. In 2003, the U.S. Environmental Protection Agency began a significant initiative to redevelop the survey, guided by the advice of a multi-disciplinary workgroup consisting of economists, engineers, survey design experts, and experienced data users, in addition to incorporating feedback from key manufacturing industries. This paper describes some of these redevelopment efforts. Issues discussed include the approach to developing the new survey instrument, methods used to evaluate (and improve) its performance, innovations in sampling, and the special development and role of outside expertise. The completely redesigned PACE survey was first administered in early 2006.

description: Using data drawn from a web‐based travel cost survey, we jointly model revealed and stated preference trip count data in an attempt to estimate the recreational use value from diving the intentionally sunk ex‐USS Oriskany. Respondents were asked to report (1) their actual trips from the previous year, (2) their anticipated trip in the next year, and (3) their anticipated trip next year assuming a second dive‐able destroyer were sunk in the same vicinity. Results from a single‐site Poisson and negative binomial travel cost model indicate an annual use value of $1,215 per diver associated with current Oriskany‐specific dive trips. Expected annual use value estimates then increase to $2,596 with the “bundling” of a second vessel alongside the Oriskany to create a multiple‐ship artificial reef area.

description: We consider the set of random Bienaymé-Galton-Watson trees with a bounded number of offspring and bounded number of generations as a statistical mechanics model: a random tree is a rooted subtree of the maximal tree; the spin at a given node of the maximal tree is equal to the number of offspring if the node is present in the random tree and equal to -1 otherwise. We introduce nearest neighbour interactions favouring pairs of neighbours which both have a relatively large offspring. We then prove (1) correlation inequalities and (2) recursion relations for generating functions, mean number of external nodes, interaction energy and the corresponding variances. The resulting quadratic dynamical system, in two dimensions or more depending on the desired number of moments, yields almost exact numerical results. The balance between offspring distribution and coupling constant leads to a phase diagram for the analogue of the extinction probability. On the transition line the mean number of external nodes in generation $n+1$ is found numerically to scale as $n^{-2}$.

description: The "Physics Beyond Colliders (PBC)" study explores fundamental physics opportunities at the CERN accelerator complex complementary to collider experiments. Three new collaborations aim to exploit the M2 beamline in the North Area with existing high-intensity muon and hadron beams, but also aspire to go beyond the current M2 capabilities with a RF-separated, high intensity hadron beam, under study. The AMBER/COMPASS++ collaboration proposes an ambitious program with a measurement of the proton radius with muon beams, as well as QCD-related studies from pion PDFs / Drell-Yan to cross section measurements for dark sector searches. Assuming feasibility of the RF-separated beam, the spectrum of strange mesons would enter a high precision era while kaon PDFs as well as nucleon TMDs would be accessible via Drell-Yan reactions. The NA64mu collaboration proposes to search for dark sector mediators such as a dark scalar A' or a hypothetical Z_mu using the M2 muon beam and complementing their on-going A' searches with electron beams. The MuonE collaboration intends to assess the hadronic component of the vacuum polarization via elastic mu-e scattering, the dominant uncertainty in the determination of (g-2)_mu. An overview of the three new experimental programs will be presented together with implications for the M2 beamline and the experimental area EHN2, based on the studies of the PBC "Conventional Beams" Working Group.

We show how to include both the positive and the negative anharmonicities in a simple and systematic fashion.

description: We test $E_6$ realisations of a generic $U(1)'$ extended Minimal Supersymmetric Standard Model (UMSSM), parametrised in terms of the mixing angle pertaining to the new $U(1)'$ sector, $θ_{E_6}$, against all currently available data, from space to ground experiments, from low to high energies. We find that experimental constraints are very restrictive and indicate that large gauge kinetic mixing and $θ_{E_6}\approx -π/3$ are required within this theoretical construct to achieve compliance with current data. The consequences are twofold. On the one hand, large gauge kinetic mixing implies that the $Z'$ boson emerging from the breaking of the additional $U(1)'$ symmetry is rather wide since it decays mainly into $WW$ pairs. On the other hand, the preferred $θ_{E_6}$ value calls for a rather specific $E_6$ breaking pattern different from those commonly studied. We finally delineate potential signatures of the emerging UMSSM scenario in both Large Hadron Collider (LHC) and in Dark Matter (DM) experiments.

Il est utilisé dans les classes de maternelle du district scolaire de Maple Ridge en Colombie-Britannique. C'était un project pilote à Burnaby en 2009, le district où mon école est située. J'ai décidé de créer et de mettre en pratique une version française du programme dan ma classe de première année. Le programme est basé sur une étude entreprise en anglais par les auteurs dans des classes de maternelle à Maple Ridge en 2002. Dans cette étude ainsi que dans la mienne, tous les élèves ont démontré une amélioration des habiletés phonologiques : la seule exception était dans les tâches de segmentation où les élèves moins performants avaient de la difficulté. Il faut noter que l'adaptation a été basée sur plus d'une simple traduction du programme de l'anglais au française car il y avait des différences linguistiques significatives. La mise en pratique du programme n'était pas simple pour des raisons pratiques, budgétaires et linguistiques. Cependant, elle a engendré d'étroites collaborations entre orthopédagogue, enseignantes de maternelle et de première année entre deux écoles d'immersion française concernant le processus de dépistage des élèves à risque d'echouer en lecture. L'utilisation de ce programme semble non seulement être idéale à la rentrée pour les élèves de la première année mais aussi il semble être approprié pour la maternelle. Cependant, plus d'études sont nécessaires à ce sujet.

description: We investigate the thermodynamical features of two Lorentzian signature backgrounds that arise in string theory as exact CFTs and possess more than two disconnected asymptotic regions: the 2-d charged black hole and the Nappi-Witten cosmological model. We find multiple smooth disconnected Euclidean versions of the charged black hole background. They are characterized by different temperatures and electro-chemical potentials. We show that there is no straightforward analog of the Hartle-Hawking state that would express these thermodynamical features. We also obtain multiple Euclidean versions of the Nappi-Witten cosmological model and study their singularity structure. It suggests to associate a non-isotropic temperature with this background.

The citation disadvantage of clinical research

description: Biomedical research encompasses diverse types of activities, from basic science ("bench") to clinical medicine ("bedside") to bench-to-bedside translational research. It, however, remains unclear whether different types of research receive citations at varying rates. Here we aim to answer this question by using a newly proposed paper-level indicator that quantifies the extent to which a paper is basic science or clinical medicine. Applying this measure to 5 million biomedical papers, we find a systematic citation disadvantage of clinical oriented papers; they tend to garner far fewer citations and are less likely to be hit works than papers oriented towards basic science. At the same time, clinical research has a higher variance in its citation. We also find that the citation difference between basic and clinical research decreases, yet still persists, if longer citation-window is used. Given the increasing adoption of short-term, citation-based bibliometric indicators in funding decisions, the under-cited effect of clinical research may provide disincentives for bio-researchers to venture into the translation of basic scientific discoveries into clinical applications, thus providing explanations of reasons behind the existence of the gap between basic and clinical research that is commented as "valley of death" and the commentary of "extinction" risk of translational researchers. Our work may provide insights to policy-makers on how to evaluate different types of biomedical research.

description: Conventional discrete choice Random Utility Maximization (RUM) models of recreation demand ignore the influence of knowledge, or site capital, gained over past trips on current site choice, despite its obvious impact. We develop a partially dynamic RUM model that incorporates a measure of site capital as an explanatory variable in an effort to address this shortcoming. To avoid the endogeneity of past and current trip choices, we estimate an auxiliary instrumental variable regression to purge site capital of its correlation with the error terms in current site utility. Our instrumental variable regression gives a fitted value ranging between 0 and 1 for each alternative for each person – a prediction of whether or not a person visited a site. Results suggest that the presence of accumulated site capital is an important predictor of current trips, and that failure to account for site capital will likely lead to underestimates of potential welfare effects.

description: Purpose. The purpose of this study was to examine the factors that affect food shocks and how vulnerable are people to food shocks using Ife North Local Government Area of Osun State Nigeria as a case study. Methodology / approach. Data were collected from 150 households through multistage sampling from ten political wards in Ife North Local Government Area. Descriptive statistics was used to describe the socio-economic characteristics and profile food shocks experienced and identify the coping strategies employed among rural households in the study area. Results. The study revealed that majority of the household age range of between 40 to 59 (62.0 %), married (77.3 %). Also, majority of the respondent own their farm (85.3 %). The result shows that the shocks that are prevalent in the study area include high price of input (66.6 %), loss of close relatives (72.0 %), low agricultural production (64.6 %), pest and disease (66.6 %), hash economic time (54.0%), and Ill health (50%). The other shocks experienced having low prevalence among households are non-availability of labour (23.4 %), accident (32.0 %), flood (31.4%), and theft (35.4 %). Originality / scientific novelty. The age categorization of vulnerability to food insecurity indicates that household heads aged 80 and above are more vulnerable to food insecurity (0.7158) followed by those within age 21–39 (0.6895). Also, the distribution of household head by their educational level shows that the household that have no formal education (0.5123) are more vulnerable to food insecurity. Practical value / implications. The implication of this study is that Government should regulate price fluctuation of agricultural goods and inputs. The use of pesticides should be encouraged to prevent pests and disease prevalence. Also, agricultural credit should be made available to farmers.
Vacuum polarization and photon mass in inflation

description: We give a pedagogical review of a mechanism through which long wave length photons can become massive during inflation. Our account begins with a discussion of the period of exponentially rapid expansion known as inflation. We next describe how, when the universe is not expanding, quantum fluctuations in charged particle fields cause even empty space to behave as a polarizable medium. This is the routinely observed phenomenon of vacuum polarization. We show that the quantum fluctuations of low mass, scalar fields are enormously amplified during inflation. If one of these fields is charged, the vacuum polarization effect of flat space is strengthened to the point that long wave length photons acquire mass. Our result for this mass is shown to agree with a simple model in which the massive photon electrodynamics of Proca emerges from applying the Hartree approximation to scalar quantum electrodynamics during inflation. A huge photon mass is not measured today because the original phase of inflation ended when the universe was only a tiny fraction of a second old. However, the zero-point energy left over from the epoch of large photon mass may have persisted during the post-inflationary universe as very weak, but cosmological-scale, magnetic fields. It has been suggested that these small seed fields were amplified by a dynamo mechanism to produce the micro-Gauss magnetic fields observed in galaxies and galactic clusters.

description: Yen et al. (2012) advanced a direct approach for the calculation of self-gravitational force to second order accuracy based on uniform grid discretization. This method improves the accuracy of N-body calculation by using exact integration of kernel functions and employing the Fast Fourier Transform (FFT) to reduce complexity of computation to nearly linear. This direct approach is free of artificial boundary conditions, however, the applicability is limited by the uniform discretization of grids. We report here an advancement in the direct method with the implementation of adaptive mesh refinement (AMR) and maintaining second-order accuracy, which breaks the barrier set by uniform grid discretization. The adoption of graphic process units (GPUs) can significantly speed up the computation and make application of this method possible to astrophysical systems of gaseous disk galaxies and protoplanetary disks.

description: The hypothesis that neutrons might decay into dark matter is explored using neutron stars as a testing ground. It is found that in order to obtain stars with masses at the upper end of those observed, the dark matter must experience a relatively strong self-interaction. Conservation of baryon number and energy then require that the star must undergo some heating, with a decrease in radius, leading to an increase in speed of rotation over a period of days.
