THE CHANDRA COSMOS LEGACY SURVEY: CLUSTERING OF X-RAY-SELECTED AGNs AT 2.9 ≤ z ≤ 5.5 USING PHOTOMETRIC REDSHIFT PROBABILITY DISTRIBUTION FUNCTIONS

We present the measurement of the projected and redshift-space two-point correlation function (2pcf) of the new catalog of Chandra COSMOS-Legacy active galactic nucleus (AGN) at 2.9 ≤ z ≤ 5.5 ( 〈 L bol 〉 ∼ 1046 erg s−1) using the generalized clustering estimator based on phot-z probability distribution functions in addition to any available spec-z. We model the projected 2pcf, estimated using πmax = 200 h−1 Mpc with the two-halo term and we derive a bias at z ∼ 3.4 equal to b = 6.6 − 0.55 + 0.60 , which corresponds to a typical mass of the hosting halos of log Mh = 12.83 − 0.11 + 0.12 h−1 M⊙. A similar bias is derived using the redshift-space 2pcf, modeled including the typical phot-z error σz = 0.052 of our sample at z ≥ 2.9. Once we integrate the projected 2pcf up to πmax = 200 h−1 Mpc, the bias of XMM and Chandra COSMOS at z = 2.8 used in Allevato et al. is consistent with our results at higher redshifts. The results suggest only a slight increase of the bias factor of COSMOS AGNs at z ≳ 3 with the typical hosting halo mass of moderate-luminosity AGNs almost constant with redshift and equal to log Mh = 12.92 − 0.18 + 0.13 at z = 2.8 and log Mh = 12.83 − 0.11 + 0.12 at z ∼ 3.4, respectively. The observed redshift evolution of the bias of COSMOS AGNs implies that moderate-luminosity AGNs still inhabit group-sized halos at z ≳ 3, but slightly less massive than observed in different independent studies using X-ray AGNs at z ≤ 2.
Secular dynamics of multiplanet systems: Implications for the formation of hot and warm Jupiters via high-eccentricity migration

Hot Jupiters (HJs) are Jupiter-like planets that reside very closely to their host star, within $\sim 0.1\,\mathrm{AU}$. Their formation is not well understood. It is generally believed that they cannot have formed in situ, implying that some form of migration must have occurred after their initial formation. We study the production of HJs through secular evolution in multiplanet systems with three to five planets. In this variant of high-$e$ migration, the eccentricity of the orbit of the innermost planet is excited on secular time-scales, triggering orbital migration due to tidal dissipation. We use a secular dynamics code and carry out a population synthesis study. We find that HJs are only produced if the viscous time-scale is short ($\approx 0.014$ yr). In contrast, in up to $\approx 0.3$ of systems, the innermost planet is tidally disrupted. The orbital period distribution is peaked around 5 d, consistent with observations. The median HJ mass is $1\,M_\mathrm{J}$ with a maximum of $\approx 2 \, M_\mathrm{J}$, similar to observed HJs. Approximately 0.1 of the HJs have retrograde orbits with respect to the stellar spin. We do not find any warm Jupiters in our simulations, i.e. planets with semimajor axes between 0.1 and 1 AU.
The exciting lives of giant molecular clouds

We present a detailed study of the evolution of giant molecular clouds (GMCs) in a galactic disc simulation. We follow individual GMCs (defined in our simulations by a total column density criterion), including their level of star formation, from their formation to dispersal. We find the evolution of GMCs is highly complex, and GMCs cannot be considered as isolated objects. GMCs often form from a combination of smaller clouds and ambient interstellar medium (ISM), and similarly disperse by splitting into a number of smaller clouds and ambient ISM. However some clouds emerge as the result of the disruption of a more massive GMC, rather than from the assembly of smaller clouds. Likewise in some cases, clouds accrete on to more massive clouds rather than disperse. Because of the difficulty of determining a precursor or successor of a given GMC, determining GMC histories and lifetimes is highly non-trivial. Using a definition relating to the continuous evolution of a cloud, we obtain lifetimes typically
Effect of a Short-Term Intervention with Lactobacillus salivarius Probiotic on Early Childhood Caries—An Open Label Randomized Controlled Trial

ECC is a significant therapeutic and social problem and a global burden on public health. The aim of this clinical trial was to test whether a 2-week daily consumption of chewing tablets containing thermally inactivated L. salivarius reduces the 12-month caries increment compared to the control group. The investigation was a single-center, randomized, controlled open-label, blinded end-point evaluation trial in two parallel groups. At baseline, 140 generally healthy children between 3 and 6 years of age with or without ECC were randomly assigned to the probiotic test group (n = 70) or to the treatment as the usual control group (n = 70). The primary outcome measure was the 1-year increment in caries incidence and prevalence. Secondary endpoints assessed were the initial, cavitated and obvious dentinal caries increment as well as the measurement of dental plaque accumulation, as an indicator of the ECC risk. Data were collected through the clinical assessment of the children’s caries (dmft and ICDAS II) and oral hygiene status (DI-S of OHI-S index). Caries incidence and prevalence were statistically significantly lower in the probiotic group versus the control group (p < 0.001 and p = 0.0075). The initial and final mean OHI-S scores in the probiotic group did not show any significant differences. In conclusion, the regular short-term intake of probiotics may reduce caries development. Our findings suggest that self-administered probiotic therapy may provide a good complement to increase the effectiveness of individual preventive home care in preschool children. This is the first clinical study evaluating the effect of a short-term probiotic intervention on reducing early childhood caries with 12 months of follow-up.
Satellite survival in highly resolved Milky Way class haloes

Surprisingly little is known about the origin and evolution of the Milky Way’s satellite galaxy companions. UV photoionisation, supernova feedback and interactions with the larger host halo are all thought to play a role in shaping the population of satellites that we observe today, but there is still no consensus as to which of these effects, if any, dominates. In this paper, we revisit the issue by re-simulating a Milky Way class dark matter (DM) halo with unprecedented resolution. Our set of cosmological hydrodynamic Adaptive Mesh Refinement (AMR) simulations, called the Nut suite, allows us to investigate the effect of supernova feedback and UV photoionisation at high redshift with sub-parsec resolution. We subsequently follow the effect of interactions with the Milky Way-like halo using a lower spatial resolution (50pc) version of the simulation down to z = 0. This latter produces a population of simulated satellites that we compare to the observed satellites of the Milky Way and M31. We find that supernova feedback reduces star formation in the least massive satellites but enhances it in the more massive ones. Photoionisation appears to play a very minor role in suppressing star and galaxy formation in all progenitors of satellite halos. By far the largest effect on the satellite population is found to be the mass of the host and whether gas cooling is included in the simulation or not. Indeed, inclusion of gas cooling dramatically reduces the number of satellites captured at high redshift which survive down to z = 0.
THE DEPENDENCE OF PRESTELLAR CORE MASS DISTRIBUTIONS ON THE STRUCTURE OF THE PARENTAL CLOUD

The mass distribution of prestellar cores is obtained for clouds with arbitrary internal mass distributions using a selection criterion based on the thermal and turbulent Jeans mass and applied hierarchically from small to large scales. We have checked this methodology by comparing our results for a log-normal density probability distribution function with the theoretical core mass function (CMF) derived by Hennebelle & Chabrier, namely a power law at large scales and a log-normal cutoff at low scales, but our method can be applied to any mass distributions representing a star-forming cloud. This methodology enables us to connect the parental cloud structure with the mass distribution of the cores and their spatial distribution, providing an efficient tool for investigating the physical properties of the molecular clouds that give rise to the prestellar core distributions observed. Simulated fractional Brownian motion (fBm) clouds with the Hurst exponent close to the value H = 1/3 give the best agreement with the theoretical CMF derived by Hennebelle & Chabrier and Chabrier's system initial mass function. Likewise, the spatial distribution of the cores derived from our methodology shows a surface density of companions compatible with those observed in Trapezium and Ophiucus star-forming regions. This method also allows us to analyze the properties of the mass distribution of cores for different realizations. We found that the variations in the number of cores formed in different realizations of fBm clouds (with the same Hurst exponent) are much larger than the expected root statistical fluctuations, increasing with H.
Flexural performance of CFRP strengthened beams - comparison with analytical model

ABSTRACT In recent years, strengthening methods for reinforced concrete structures using fibre-reinforced polymer (FRP) composites have been gaining widespread interest and growing acceptance in civil engineering industry. Near surface mounted (NSM) reinforcement as well as externally bonded reinforcement (EBR) sheets have emerged as new strengthening methods in which external reinforcement (in the form of bars or sheets) is embedded into grooves or adhered to the section with epoxy adhesive. This paper proposes a simplified analytical approach to predict flexural behaviour of simply supported reinforced-concrete (RC) beams strengthened with carbon fibre-reinforced polymer (CFRP) using the above-mentioned methods. The flexural capacity and deformational behaviour of FRP strengthened beams are analysed using trilinear moment curvature relationship at three critical points namely (i) crack initiation point (ii) steel yield initiation point and (iii) ultimate capacity point, based on strain compatibility and principles of equilibrium. A good predictive performance of analytical model is appraised by simulating force-deflection response registered in the experimental program composed of RC beams strengthened with NSM as well as EBR methods. The analytical solutions have also given accurate prediction of experimental results in the literature regardless of the arrangement of CFRP reinforcement.
Synchronization in periodically driven and coupled stochastic systems-A discrete state approach

We investigate the behavior of stochastic bistable and excitable dynamics based on a discrete state modeling. In addition to the well known Markovian two state model for bistable dynamics we introduce a non Markovian three state model for excitable systems. Its relative simplicity compared to stochastic models of excitable dynamics with continuous phase space allows to obtain analytical results in different contexts. First, we study the joint influence of periodic signals and noise, both based on a characterization in terms of spectral quantities and in terms of synchronization properties with the driving signal. We present expressions for the spectral power amplification and signal to noise ratio for renewal processes driven by weak periodic signals. Applying these results to the discrete model for excitable systems allows to estimate signal frequencies which are optimally amplified by the stochastic system. Stochastic synchronization of the system to the driving signal is investigated based on diffusion properties of the transition events between the discrete states. We derive general results for the mean frequency and effective diffusion coefficient which, beyond the application to the discrete models considered in this work, provide a new tool in the study of periodically driven renewal processes. Applied to the dichotomically driven Markovian two state model for bistable system exact analytical results are obtained. While this system only exhibits one to one synchronization the three state model for excitable system shows different m : n synchronization regimes. The very same discrete model for excitable systems can also be considered as a simple model for a molecular motor. We show that an appropriate periodic modulation of the concentration of the fuel molecules can lead to a very regular motion of the motor. Finally the behavior of globally coupled excitable and bistable units is investigated based on the discrete state description. In contrast to the bistable systems, the excitable system exhibits synchronization and thus coherent oscillations. A non vanishing refractory period as well as an excitatory coupling are shown to be necessary conditions for synchronous firing to occur. All investigations of the non Markovian three state model are compared with the prototypical continuous model for excitable dynamics, the FitzHugh-Nagumo system. They reveal a good agreement between both models, rendering the non Markovian discrete state model for excitable systems an appropriate simplification of continuous phase space dynamics commonly used in the modeling of excitable dynamics.
Sommerfeld enhancements with vector, scalar and pseudoscalar force-carriers

The first AMS-02 measurement confirms the existence of an excess in the cosmic-ray positron fraction previously reported by the PAMELA and Fermi-LAT experiments. If interpreted in terms of thermal dark matter (DM) annihilation, the AMS-02 result still suggests that the DM annihilation cross section in the present day should be significantly larger than that at freeze-out. The Sommerfeld enhancement of the DM annihilation cross section is a possible explanation, which is however subject to the constraints from DM thermal relic density, mainly due to the annihilation of DM particles into force-carrier particles introduced by the mechanism. We show that the effects of the Sommerfeld enhancement and the relic density constraints depend significantly on the nature of the force carrier. Three scenarios where the force carrier is a vector boson, scalar, and pseudoscalar particle are investigated and compared. The results show that for the case with a vector force carrier, the Sommerfeld enhancement can marginally account for the AMS-02 data for the DM particle annihilating into 2 mu final states, while for the scalar force carrier the allowed Sommerfeld enhancement factor can be larger by a factor of 2. For the case with a pseudoscalar force carrier, the Sommerfeld enhancement factor can be very large in the resonance region, and it is possible to accommodate the AMS-02 and Fermi-LAT result for a variety of DM annihilation final states.
Incidence and therapy of relapse after allogenic hematopoietic stem cell transplantation

Introduction/Aim: Disease relapse after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is one of the most common and most severe post transplantation complications and represents the leading cause of treatment failure and patient death. The aim of this study is to assess the frequency and types of relapse, in relation to the time of occurrence; analyze the influence of conditioning regimens on relapse occurrence; review the therapeutic options after the occurrence of relapse; assess the prognosis in patients with relapse. Methods: This retrospective cohort study included 58 patients who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT). Pre-transplantation therapy was performed with a reduced-intensity conditioning regimen (RIC) or a myeloablative regimen (MAC). The diagnosis of relapse was made through myelogram analysis, analysis of cytogenetics, analysis of minimal residual disease (MRD), analysis of cellular chimerism, and analysis of immunohematological chimerism of blood group antigens. A database was formed in relation to the examined patient characteristics. Patient survival was analyzed using the Kaplan-Meier method and the log-rang test. Results: MAC (43 patients) was used more frequently than RIC (15 patients), as a conditioning regimen. After transplantation, 18 (34%) out of 53 patients had a relapse. The choice of regimen did not affect the occurrence of relapse, but patients on the RIC regimen lived longer (38.5 ± 7 months) as compared to patients on the MAC regimen (27.8 ± 3.5 months). However, the difference in survival was without statistical significance (p = 0.318). The median survival time of patients who relapsed was 26 ± 5 months, while patients without disease relapse had a median survival time of 41 ± 4 months. Conclusion: Patients who received reduced-intensity regimens (RIC) had a longer survival time, without an increase in the relapse rate. In future, consideration should be given to the inclusion of patients older than 60 years, as candidates for transplantation, as well as to the possible use of prophylactic therapy aimed at preventing relapse in high-risk patients.
TESTING DARK MATTER HALO MODELS OF QUASARS WITH THERMAL SUNYAEV–ZELDOVICH EFFECT

A statistical analysis of stacked Compton-y maps of quasar hosts with a median redshift of 1.5 using Millennium Simulation is performed to address two issues: one on the feedback energy from quasars and the other on testing dark matter halo models for quasar hosts. On the first, we find that at the resolution of FWHM = 10 arcmin obtained by Planck data, the observed thermal Sunyaev–Zeldovich (tSZ) effect can be entirely accounted for and explained by the thermal energy of halos sourced by the gravitational collapse of halos, without a need to invoke additional, large energy sources, such as quasar or stellar feedback. Allowing for uncertainties of dust temperature in the calibration of observed Compton-y maps, the maximum additional feedback energy is ∼ 25 % ? > of that previously suggested. Second, we show that with an FWHM = 1 arcmin beam, tSZ measurements will provide a potentially powerful test of quasar-hosting dark matter halo models, limited only by possible observational systematic uncertainties, not by statistical ones, even in the presence of possible quasar feedback.
Going qual in: Towards methodologically inclusive data work in academic libraries

Data literacy and research data services are a growing part of the work of academic libraries. Data in this context is often presumed to mean only numeric data or statistics, leaving open the question of what role qualitative research plays in services and programming for research data and data literacy. In this paper, we report on the results of interviews with academic librarians about their understanding of data literacy, qualitative research, and academic library infrastructure around qualitative research. From the interviews, we propose a model of data literacy that incorporates both interpretive and instrumental elements. We conclude with suggestions for incorporating qualitative data and analysis methods into academic library programming and services around data literacy and research data.
The Role of Human Resources Management Practices in Employee Job Satisfaction in Salaam Bank: The Moderating Role of Organizational Justice

Purpose –Despite the obvious significance of human resources in an organization, their wellbeing over time has largely been taken for granted by some organizations.The purpose of this study is to analyze the role of human resource management (HRM) practices in employee job satisfaction.Design/methodology/approach –A case study approach and primary data collection method were used to gathered quantitative data for the study through structured, self-administered questionnaires with five-point Likert scale. A stratified random sampling technique was used to obtain sample population, including 692 full-time employees in Salaam Bank Mogadishu-Somalia. The collected data was coded to Statistical Package for the Social Sciences (SPSS). Findings–According to the results, planning and recruitment, training programs, employee compensation, andperformance appraisal have all significant impact on employees’ satisfaction. Moreover, coefficient analyses of three independent variables, namely planning and recruitment,employee compensation, andperformance appraisal crossed with organizational justice imply existence of a moderating effect between each of these three independent variables and organizational justice; while no moderating effect was found between training programs and organizational justice.Discussion–The outcome of the researchprovides a basis for bank managers to recognize the HRM practices that leads to higher employee job satisfaction. Accordingly, bank managers should adopt an efficient planning and recruitment, training, compensation, and appraisal system to achieve further job satisfaction. Since this research’s focus is on private sector, future research is required to be extended to other districts and consider public institution as well.
Physicochemical characterization and bioactive potential in Dovyalis hebecarpa Warb fruits

Ceylon gooseberry (Dovyalis hebecarpa Warb) is an important and valuable food source in the diet of several countries worldwide with a potential to positively impact nutritional security. This study aimed to evaluate the physicochemical attributes, bioactive compounds, and antioxidant capacity of D. hebecarpa fruits grown in Marechal Cândido Rondon/PR. The following parameters were assessed: fresh weight, longitudinal and transverse length, LD/TD (format index), yield in pulp, peel, and seed, soluble solids, titratable acidity, SS/TA (flavor index), pH, ascorbic acid, total carotenoids, yellow flavonoids, total anthocyanins, total chlorophyll, phenolic compounds, and antioxidant capacity (DPPH and FRAP). The review and results of study on ripe fruits of D. hebecarpa in Marechal Cândido Rondon/PR revealed that it contains significant levels of soluble solids (18.25 °Brix), good pulp yield (90.19%), and high levels of ascorbic acid (142.09 mg/100g-1 of pulp) and total anthocyanins (94.13 mg/100g-1 of peel). This information confirms that the fruits of D. hebecarpa can be successfully used for the formulation and development of new products, in addition to the utilization of other parts, such as peels and seeds.
Stress Drops of Intermediate‐Depth and Deep Earthquakes in the Tonga Slab

Multiple physical mechanisms have been proposed to explain the cause of intermediate‐depth and deep earthquakes, but they are still under debate. Source parameters such as stress drop, have the potential to provide insight into their physical mechanisms. We develop a modified spectral decomposition method to analyze 1‐year seismic data from temporary land‐based and ocean bottom seismographs in a complex subduction zone. By applying this method to investigate 1,083 intermediate‐depth and deep earthquakes in the Tonga slab, we successfully resolve the source spectra and stress drops of 743 MW 2.6–6.0 earthquakes. Although the absolute stress drops are subject to the choices of source model parameters, the relative stress drops are more reliably resolved. The median stress drop of Tonga earthquakes does not change with respect to magnitude but decreases with depth by 2–3 times in two separate depth ranges of 70–250 and 400–600 km, corresponding to intermediate‐depth and deep earthquakes, respectively. The median stress drops show spatial variations, with two high‐stress‐drop (five times higher than the ambient value) regions, coinciding with strong local deformation where the Tonga slab bends or tears. In the Tonga double seismic zone at 120–300 km depths, the median stress drop appears smaller in the lower plane than in the upper plane, suggesting a slower rupture velocity or a higher fluid content in the lower‐plane region. Our results suggest that intermediate‐depth and deep earthquakes in the Tonga slab generally follow the earthquake self‐similar model and favor the fluid‐related embrittlement hypothesis for both groups of earthquakes.
