Criticality and Inflation of the Gauged B-L Model

We consider the multiple point principle (MPP) and the inflation of the gauged B-L extension of the Standard Model (SM) with a classical conformality. We examine whether the scalar couplings and their beta functions can become simultaneously zero at $\Lambda_{\text{MPP}}:=10^{17}$ GeV by using the two-loop renormalization group equations (RGEs). We find that we can actually realize such a situation and that the parameters of the model are uniquely determined by the MPP. However, as discussed in \cite{Iso:2012jn}, if we want to realize the electroweak symmetry breaking by the radiative B-L symmetry breaking, the self coupling $\lambda_{\Psi}$ of a newly introduced SM singlet complex scalar $\Psi$ must have a non-zero value at $\Lambda_{\text{MPP}}$, which means the breaking of the MPP. We find that the ${\cal{O}}(100)$GeV electroweak symmetry breaking can be achieved even if this breaking is very small; $\lambda_{\Psi}(\Lambda_{\text{MPP}})\leq10^{-10}$. Within this situation, the mass of the B-L gauge boson is predicted to be \begin{equation} M_{B-L}=2\sqrt{2}\times\sqrt{\frac{\lambda(v_{h})}{0.10}}\times v_{h}\simeq 696\hspace{1mm}\text{GeV},\nonumber\end{equation} where $\lambda$ is the Higgs self coupling and $v_{h}$ is the Higgs expectation value. This is a remarkable prediction of the (slightly broken) MPP. Furthermore, such a small $\lambda_{\Psi}$ opens a new possibility: $\Psi$ plays a roll of the inflaton \cite{Okada:2011en}. Another purpose of this paper is to investigate the $\lambda_{\Psi}\Psi^{4}$ inflation scenario with the non-minimal gravitational coupling $\xi\Psi^{2} {\cal{R}}$ based on the two-loop RGEs.
Academic Environment and Students’ Learning: Causal Perspective of Secondary School Level in Dera Ghazi Khan

The study aims to find out students’ perception about various aspects of academic environment at school and to depict the impact of academic environment on students’ learning. This study also discovers whether these two variables exist at the same standard in public and private sectors or there is any variation in availability or relation? The study employed descriptive survey method. The population of the study was the secondary class students of all Public and Private Secondary Schools in Dera Ghazi Khan district. Two stage random technique was adopted to determine the sample size. At first stage 10 public sector and 10 private secondary school from Dera Ghazi Khan with equal ratio of male and female schools. At the second stage 25 students from each school were randomly selected. Total sample size for the study was consisted on 500 secondary school students. The researchers used the questionnaire and an achievement test in English as data collection instruments. The collected data was analysed by calculated mean score and Standard Deviation. t-test and co relational tests were applied to find out the relation between academic environment at school and students’ learning. The study concluded that there was a positive co-relation between academic environment and students’ learning. The study also recommended that secondary school management should focus in ensuring positive academic environment at school to enhance students’ learning output and overall growth and development.
THE CHALLENGES OF ENVIRONMENTAL HEALTH ON THE SCIENCE CURRICULUM ON THE LAST YEARS OF ELEMENTARY EDUCATION, IN THE STATE OF TOCANTINS

Environmental Health is an area of knowledge that goes through many curricular components, especially in the Natural Sciences, an important field to develop it. It should be related to the teachers' preparation to work in a critical way with a bias towards scientific literacy. This study aimed to evaluate the challenges faced by teachers in the area of Natural Sciences to implement Environmental Health in the Final Years of Elementary School, in the state of Tocantins. A quantitative and qualitative research identified a high percentage of young teachers, with higher prevalence to teach expository lessons and little appropriation of scientific literacy. Although the teachers indicated little difficulty in working with the themes of Environmental Health, they reported the need for continued education.
Track Running Shoes: A Case Report of the Transition from Classical Spikes to “Super Spikes” in Track Running

Research on high-tech running shoes is increasing but few studies are available about the use of high-tech track spike shoes (super spikes), despite their growing popularity among running athletes. The aim of this case study was to investigate kinematics, kinetics, and plantar pressures of an Olympic running athlete using two different types of shoes, to provide an easy and replicable method to assess their influence on running biomechanics. The tested athlete performed six running trials, at the same speed, wearing a pair of normal spikes shoes (NSS) and a super spikes shoe (SSS), in random order. SSS increased contact time, vertical impact, and swing force (Effect Size 3.70, 7.86, and 1.31, respectively), while it reduced foot-strike type and vertical ground reaction force rate (Effect Size 3.62 and 7.21, respectively). Moreover, a significant change was observed in medial and lateral load, with SSS inducing a more symmetrical load distribution between the left and right feet compared to the NSS (SSS left medial load 57.1 ± 2.1%, left lateral load 42.9 ± 1.4%, right medial load 55.1 ± 2.6%, right lateral load 44.9 ± 2.6%; NSS left medial load 58.4 ± 2.6%, left lateral load 41.6 ± 2.1%, right medial load 49.2 ±3.7%, right lateral load 50.8 ± 3.7%). The results of this case study suggest the importance of using individual evaluation methods to assess shoe adaptations in running athletes, which can induce biomechanical modifications and should be considered by coaches to ensure optimal running performance.
Comparison of magnetic perturbation data from LEO satellite constellations: Statistics of DMSP and AMPERE

During the past decade engineering‐grade magnetic field measurements from the low Earth orbiting (LEO) Iridium constellation of communication satellites have been available to the geospace science community as a tool to map field‐aligned currents. The Active Magnetosphere and Planetary Electrodynamics Response Experiment (AMPERE) applied to Iridium measurements markedly improved the temporal and spatial resolution of these data. We developed new methods to compare data from the latest improvement to AMPERE with those from a constellation of four LEO Defense Meteorological Satellite Program (DMSP) spacecraft that carry high‐resolution magnetometers. To perform the comparisons, we transformed all data to a common coordinate frame and altitude (110 km) and developed a means of computing spacecraft magnetic conjunctions. These conjunctions yield discrepancies in the magnetic field perturbations measured at each proximate spacecraft. During the geomagnetic disturbance of 29–30 May 2010, the vector differences in the horizontal perturbations at closest approach (typically a few tens of kilometers) had mean, median, and standard deviation values of 132 nT, 112 nT, and 90 nT, respectively. The DMSP spacecraft tend to report larger perturbations in the northern polar cap and cusp regions, especially during active intervals. We attribute some of the differences to limitations of spacecraft‐attitude knowledge that propagate into AMPERE data. Overall, for the magnetic storm, we provide clear evidence that AMPERE data can provide high‐resolution auroral zone data in good agreement with DMSP data for use in data assimilation algorithms. Such dual‐use commercial data can provide important global augmentation to the nation's space weather monitoring capabilities.
Halo-independent tests of dark matter direct detection signals: local DM density, LHC, and thermal freeze-out

From an assumed signal in a Dark Matter (DM) direct detection experiment a lower bound on the product of the DM-nucleon scattering cross section and the local DM density is derived, which is independent of the local DM velocity distribution. This can be combined with astrophysical determinations of the local DM density. Within a given particle physics model the bound also allows a robust comparison of a direct detection signal with limits from the LHC. Furthermore, the bound can be used to formulate a condition which has to be fulfilled if the particle responsible for the direct detection signal is a thermal relic, regardless of whether it constitutes all DM or only part of it. We illustrate the arguments by adopting a simplified DM model with a Z′ mediator and assuming a signal in a future xenon direct detection experiment.
Non-conservative evolution in Algols: where is the matter?

Context. There is gathering indirect evidence suggesting non-conservative evolutions in Algols. However, the systemic mass-loss rate is poorly constrained by observations and generally set as a free parameter in binary-star evolution simulations. Moreover, systemic mass loss may lead to observational signatures that are stil l to be found. Aims. Within the ‘hotspot’ ejection mechanism, some of the materi al that is initially transferred from the companion star via an accretion stream is expelled from the system due to the radiative energy released on the gainer’s surface by the impactin g material. The objective of this paper is to retrieve observable quanti ties from this process, and to compare them with observations. Methods. We investigate the impact of the outflowing gas and the possib le presence of dust grains on the spectral energy distributi on (SED). We used the 1D plasma code Cloudy and compared the results with the 3D Monte-Carlo radiative transfer code Skirt for dusty simulations. The circumbinary mass-distribution and binary parameters are computed with state-of-the-art binary calculations done with the Binstar evolution code. Results. The outflowing material reduces the continuum flux-level of t he stellar SED in the optical and UV. Due to the timedependence of this effect, it may help to distinguish between different ejection mechanisms. Dust, if present, leads to obser vable infrared excesses even with low dust-to-gas ratios and traces the cold material at large distances from the star. By sear ching for such dust emission in the WISE catalogue, we found a small number of Algols showing infrared excesses, among which the two rather surprising objects SX Aur and CZ Vel. We find that some binary B [e] stars show the same strong Balmer continuum as we predict with our models. However, direct evidence of systemic mass loss is probably not observable in genuine Algols, since these systems no longer eject mass through the hotspot mechanism. Furthermore, owing to its high velocity, the outflowing material dis sipates in a few hundred years. If hot enough, the hotspot may produce highly ionised species such as Siiv and observable characteristics that are typical of W Ser systems. Conclusions. Systemic mass loss, if present, leads to clear observationa l imprints. These signatures are not to be found in genuine Algols but in the closely relatedβ Lyraes, W Serpentis stars, Double Periodic Variables, Symbiotic Algols and binary B[e] stars. We emphasise the need for further observations of such objects where systemic mass loss is most likely to occur.
Fluctuations in the high-redshift Lyman–Werner background: close halo pairs as the origin of supermassive black holes

The earliest generation of stars and black holes must have established an early ' 'Lyman-Werner' background (LWB) at high redshift, prior to the epoch of reionization. Because of the long mean free path of photons with energies hv 99 per cent of the DM haloes are illuminated by an LW flux within a factor of 2 of the global mean value. However, a small fraction, ∼10 -8 to 10 -6 , of DM haloes with virial temperatures T vir ≥ 10 4 K have a close luminous neighbour within ≤10 kpc, and are exposed to an LW flux exceeding the global mean by a factor of >20, or to J 21,LW > 10 3 (in units of 10 -21 erg s -1 Hz -1 sr -1 cm -2 ). This large LW flux can photodissociate H 2 molecules in the gas collapsing due to atomic cooling in these haloes, and prevent its further cooling and fragmentation. Such close halo pairs therefore provide possible sites in which primordial gas clouds collapse directly into massive black holes (MBH ≈10 4-6 M ⊙ ), and subsequently grow into supermassive (M BH ≥ 10 9 M ⊙ ) black holes by z ≈ 6.
Infrared-faint radio sources: a new population of high-redshift radio galaxies

We present a sample of 1317 Infrared-Faint Radio Sources (IFRSs) that, for the first time, are reliably detected in the infrared, generated by cross-correlating the Wide-Field Infrared Survey Explorer (WISE) all-sky survey with major radio surveys. Our IFRSs are brighter in both radio and infrared than the first generation IFRSs that were undetected in the infrared by the Spitzer Space Telescope. We present the first spectroscopic redshifts of IFRSs, and find that all but one of the IFRSs with spectroscopy has z > 2. We also report the first X-ray counterparts of IFRSs, and present an analysis of radio spectra and polarization, and show that they include Gigahertz-Peaked Spectrum, Compact Steep Spectrum, and Ultra-Steep Spectrum sources. These results, together with their WISE infrared colours and radio morphologies, imply that our sample of IFRSs represents a population of radio-loud Active Galactic Nuclei at z > 2. We conclude that our sample consists of lower-redshift counterparts of the extreme first generation IFRSs, suggesting that the fainter IFRSs are at even higher redshift.
ILLNESS PERCEPTION AND PERCEIVED STRESS AS PREDICTORS OF QUALITY OF LIFE AMONG OUTPATIENTS OF FEDERAL NEURO- PSYCHIATRIC HOSPITAL, YABA, LAGOS.

Purpose: Empirical evidence have shown that psychiatric out-patients often experience difficulties with getting back to normal family and work routines and relapse. This stimulated this study and made it imperative to examine the extent to which illness perception and perceived stress are implicated in fostering successful re-integration of out-patients back into the society, enhance total adherence to intake of prescribed medications, and increase being compliant to attending check-up at due time, among others. Methodology: The study investigated illness perception and perceived stress as predictors of quality of life among psychiatric patients in Federal Neuro-Psychiatric Hospital Yaba, using predictive design. The research sample consisted of sixty-one (61) out-patients at Federal Neuro-Psychiatric Hospital, Yaba. This comprised of thirty-nine (39; 63.9%) males and twenty two (22; 36.1%) females with mean age of 34.29, S.D 5.60, respectively. The participants were selected by the researcher using purposive sampling technique. They were individually administered the World Health Organization Quality of Life (WHOQOL) – Brief scale, Illness Perception Questionnaire-revised (IPQ-R), and Perceived Stress Scale (PSS). Multiple linear regression statistics was used for testing research hypothesis. Findings: The result revealed significant positive influence of illness perception on quality of life (R2= .048, R2 (adjusted) = . 015; β = . 205, p<. 05). It further revealed that perceived stress significant predicted quality of life (R2= .048, R2 (adjusted) = . 015; β = . 061, p<. 05). The researcher attributed these findings to the fact that psychiatric out-patients may by virtue of their health conditions might still not come to terms with their re-integration. Recommendation: As a result of the study findings, psychiatric outpatients should be exposed to programmes and psycho-education capable of promoting positive view of their health. Doing so will result to having positive illness perception leading to improve quality of life, since the two variables shared positive relationship. It also recommends that the process of re-integrating psychiatric outpatients back into the society should be done very well, amidst equipping them with required skills and knowledge they will need in handling the stressors they will face, positively.
Evaluation of Neurotoxicity in BALB/c Mice following Chronic Exposure to Polystyrene Microplastics

Background: The toxicity of microplastics (MPs) has attracted wide attention from researchers. Previous studies have indicated that MPs produce toxic effects on a variety of organs in aquatic organisms and mammals. However, the exact neurotoxicity of MPs in mammals is still unclear. Objectives: We aimed to confirm the neurotoxicity of chronic exposure to polystyrene MPs (PS-MPs) at environmental pollution concentrations. Methods: In the present study, mice were provided drinking water containing 100μg/L and 1,000μg/L PS-MPs with diameters of 0.5, 4, and 10μm for 180 consecutive days. After the exposure period, the mice were anesthetized to gain brain tissues. The accumulation of PS-MPs in brain tissues, integrity of the blood–brain barrier, inflammation, and spine density were detected. We evaluated learning and memory ability by the Morris water maze and novel object recognition tests. Results: We observed the accumulation of PS-MPs with various particle diameters (0.5, 4, and 10μm) in the brains of exposed mice. Meanwhile, exposed mice also exhibited disruption of the blood–brain barrier, lower level of dendritic spine density, and an inflammatory response in the hippocampus. In addition, exposed mice exhibited cognitive and memory deficits compared with control mice as determined using the Morris water maze and novel object recognition tests, respectively. There was a concentration-dependent trend, but no particle size-dependent differences were seen in the neurotoxicity of MPs. Conclusions: Collectively, our results suggested that PS-MPs exposure can lead to learning and memory dysfunctions and induce neurotoxic effects in mice, findings which have wide-ranging implications for the public regarding the potential risks of MPs. https://doi.org/10.1289/EHP10255
Simple ELISA Methods to Estimate Neutralizing Antibody Titers to SARS-CoV-2: IgG Quantification, the Avidity Index, and the Surrogate Virus Neutralization Test

Antibody the Surrogate Neutralization Test. Abstract A total of 104 sera sampled from vaccinated (“Sputnik V”, Russia) volunteers were tested in parallel to determine different markers of humoral immunity against SARS-CoV-2. Testing was conducted using the neutralizing antibodies titer (NtAb) in the virus neutralization assay (VNA), the IgG to RBD in the quantitative ELISA (BAU/ml), the avidity index (AI) of the IgG to RBD (also in ELISA), and the titers of “neutralizing antibodies” which can block an interaction between human ACE2 and the viral RBD proteins in a competitive ELISA surrogate virus neutralization test (sVNT). The correlation coefficients between the quantitative results in the tried ELISA assays and the “true” NtAb titers in the VNA were high, with the following values: r=0.86 for BAU/ml (95% confidence interval, CI: 0.80-0.91, p<0.0001); 0.54 for the AI (95% CI: 0,38-0,67, p<0.0001); and 0.84 for the sVNT titer (95% CI:0.79-0.90). Additionally, it was found that the multiplicative index of BAU/ml × AI (which corresponds to the concentration of the high-affinity fraction of the total IgG to the RBD) gives a maximum correlation to the NtAb titers (r=0.89, 95% CI: 0.84-0.92, p<0.0001). The sensitivity and specificity, respectively, of the tested ELISA assays in recognizing the supposedly protective NtAb titer of ≥1:160 were the following: for the BAU/ml – 87.7±8% and 97.4±5%; for the (BAU/ml ×
Information Spillovers Prior to M&A Announcements

In this paper, I study trading activities prior to M&A announcements pertaining to the rivals of the merging firms. I find that not only acquirers and targets experience increases in abnormal trading activities in stock and option markets, but also their rivals. The rise in option trading is especially strong for options that informed traders are most likely to trade. I find that the implied volatility spread (IV spread) constructed from a rival’s option prices the day before the announcement can predict this rival’s cumulative abnormal return (CAR) over the M&A announcement window. As the IV spread is widely adopted as a proxy for informed trading activities in the option market, my findings provide evidence for information spillovers from merging firms to their rivals prior to the announcements of the M&A deals.
Trajectories of East Asian Buddhism in South Africa: a comparative perspective

ABSTRACT In this article I take my cue from Michel Clasquin-Johnson’s reflections on six main themes (lay practice, gender equality, adhesion to democratic principles, impact of Western psychology, social engagement, creation of a non-sectarian tradition) underlying the development of mainstream South African Buddhism to explore three forms of East Asian Buddhism operating in the country: the Dharma Centre (Korean Sŏn)—a representative of mainstream South African Buddhism—and the local branches of two large new religious movements—the Japan-based Soka Gakkai International (Nichiren Buddhism) and the Taiwan-based Foguangshan (Chinese Pure Land/Chan Buddhism)—which include a more diverse section of the South African population. Besides providing a detailed analysis of these forms of East Asian Buddhism in the country, I test the applicability of Clasquin-Johnson’s themes to the case studies and explore four further topics for the comparative study of South African Buddhism: interactions with local religions, proselytization, hybridization, the promise of worldly benefits.
Strong thermal Leptogenesis: an exploded view of the low energy neutrino parameters in the SO(10)-inspired model

Leptogenesis is an attractive scenario in which neutrino masses and baryon asymmetry of the Universe are explained together under a minimal set of assumptions. After formulating the problem of initial conditions and introducing the strong thermal leptogenesis conditions as solution, we show that, within the framework provided by the \soten~model of leptogenesis, the latter lead to a set of testable predictions on the same neutrino parameters currently under experimental investigations. The emerging scenario selects the normal ordering of the neutrino mass pattern, a large value for the reactor mixing angle, $2\deg \lesssim \theta_{13} \lesssim 20\deg$, as well as a non maximal atmospheric mixing angle, $16\deg \lesssim \theta_{23} \lesssim 41\deg$, and favours negative values for the Dirac phase \delta. The signature of the proposed strong thermal \soten~solutions is in the relation obtained between the effective Majorana mass and the lightest neutrino mass: $m_{ee} \approx 0.8 \, m_1 \approx 15 $ meV.
