A NEW SAMPLE OF OBSCURED AGNs SELECTED FROM THE XMM-NEWTON AND AKARI SURVEYS

We report a new sample of obscured active galactic nuclei (AGNs) selected from the XMM-Newton serendipitous source and AKARI point-source catalogs. We match X-ray sources with infrared (18 and 90 μm) sources located at ∣ b ∣ > 10 ° ? > to create a sample consisting of 173 objects. Their optical classifications and absorption column densities measured by X-ray spectra are compiled and study efficient selection criteria to find obscured AGNs. We apply the criteria (1) X-ray hardness ratio defined by using the 2–4.5 keV and 4.5–12 keV bands > −0.1 and (2) EPIC-PN count rate (CR) in the 0.2–12 keV to infrared flux ratio CR/ F 90 < 0.1 ? > or CR/ F 18 < 1 , ? > where F18 and F90 are infrared fluxes at 18 and 90 μm in Jy, respectively, to search for obscured AGNs. X-ray spectra of 48 candidates, for which no X-ray results have been published, are analyzed and X-ray evidence for the presence of obscured AGNs such as a convex shape X-ray spectrum indicative of absorption of N H ? > ∼ 1022–24 cm−2, a very flat continuum, or a strong Fe–K emission line with an equivalent width of > 700 eV ? > is found in 26 objects. Six of them are classified as Compton-thick AGNs, and four are represented by either Compton-thin or Compton-thick spectral models. The success rate of finding obscured AGNs combining our analysis and the literature is 92% if the 18 μm condition is used. Of the 26 objects, 4 are optically classified as an H ii nucleus and are new “elusive AGNs” in which star formation activity likely overwhelms AGN emission in the optical and infrared bands.
The Termination Clause as a Sequential Screening Device ∗

In a takeover setting in which buyers arrive sequentially and the value uncertainty is resolved over time, we show that a termination clause can serve as a device for the target ﬁrm to sequentially screen the initial buyer. The initial buyer with an optimistic estimate accepts a contract with a high ﬂoor price and high termination fee to mitigate future competition; a pessimistic initial buyer, in contrast, chooses to stay ﬂexible by accepting a low price and low termination fee. We characterize the revenue-maximizing contract and provide a rationale for the use of go-shop provisions in the M&A market.
RFC1-Related Disease

In 2019, a biallelic pentanucleotide repeat expansion in the gene encoding replication factor C subunit 1 (RFC1) was reported as a cause of cerebellar ataxia with neuropathy and vestibular areflexia syndrome (CANVAS). In addition, biallelic expansions were shown to account for up to 22% of cases with late-onset ataxia. Since this discovery, the phenotypic spectrum reported to be associated with RFC1 expansions has extended beyond the initial conditions to include pure cerebellar ataxia, isolated somatosensory impairment, combinations of the 2, and parkinsonism, leading to a potentially broad differential diagnosis. Genetic studies suggest RFC1 expansions may be the most common genetic cause of ataxia and are likely underdiagnosed. This review summarizes the current molecular and clinical knowledge of RFC1-related disease, with a focus on the evaluation of recent phenotype associations and highlighting the current challenges in clinical pathways to diagnosis and molecular testing.
Pre-proof What makes tourists adopt smart hospitality? An inquiry beyond the technology acceptance model

Smart hospitality has become an attractive project in tourism. Extant research has studied smart technology as a contingency but has neglected to conceptualize smartness and investigate its consequences. This study conceptualizes and operationalizes smart hospitality and explores the relationships among smartness, perceived usefulness, perceived ease of use, overall image of a hotel and tourists’ behavioral intention to stay in a smart hotel. The proposed model incorporated technology acceptance model (TAM) and image theory. With a sample of 348 respondents in Macau, this study tested the model using partial least squares path modeling (PLS-PM), which indicates that the proposed model fits the data. In spite of a high inter-construct correlation, the results showed that smartness does not have a direct effect on behavioral intention. According to mediation analysis, indirect effects made up of significant direct effects and assigned them to TAM, image theory, and a combination of both. This paper contributes to hospitality management theory by providing additional insight into smart hospitality, it demonstrates the applicability of PLS-PM with composite and common factor models in technological change research, and it suggests smartness as a business strategy that can change tourists’ choices in practice.
Influence of Tactical Levels in School and Extracurricular Football

Recently, an instrument has been proposed to evaluate tactics in school and extracurricular football based on three levels (team, small groups and individual). The aim of the study was to find out to what extent each tactical level contributed to the successful completion of the attack and defence phases in introductory football. 88 children participated (age: M = 10.38, SD = 0.77 years) from eight male football teams (9-12 years old). 1,516 ball possessions from four official matches of the season were analysed. The observational methodology was used through an idiographic, timely and multidimensional design. Two observers viewed the videos of the matches and individually recorded four teams. The observation instrument was Tactical Assessment Instrument for Soccer . It was made up of 11 criteria divided into the three tactical levels, differentiated into attack and defence. Spearman’s Rho test and logistic regression were used for data analysis. The individual and team level actions were the ones that explained the success in the attack and defence phases at a higher percentage. However, the correlations showed the relationship between the three tactical levels and success in the attack and defence phases. Consequently, tactical training in introductory football is suggested, based on the inclusion of the three tactical levels analysed in this study (team, small groups and individual).
CONSTRAINING GLOBULAR CLUSTER AGE UNCERTAINTIES USING THE IR COLOR–MAGNITUDE DIAGRAM

Globular Clusters (GCs) in the Milky Way are the primary laboratories for establishing the ages of the oldest stellar populations and for measuring the color–magnitude relation of stars. In infrared (IR) color–magnitude diagrams (CMDs), the stellar main sequence (MS) exhibits a “kink” due to opacity effects in M dwarfs such that lower mass and cooler dwarfs become bluer in the IR color baseline. This diagnostic offers a new opportunity to model GC CMDs and to reduce uncertainties on cluster properties (e.g., their derived ages). In this context, we analyzed Hubble Space Telescope Wide Field Camera 3 IR archival observations of four GCs—47 Tuc, M4, NGC 2808, and NGC 6752—for which the data are deep enough to fully sample the low-mass MS, reaching at least ≃2 mag below the “kink. ” We derived the fiducial lines for each cluster and compared them with a grid of isochrones over a large range of parameter space, allowing age, metallicity, distance, and reddening to vary within reasonable selected ranges. The derived ages for the four clusters are, respectively, 11.6, 11.5, 11.2, and 12.1 Gyr and their random uncertainties are 0.7–1.1 Gyr. Our results suggest that the near-IR MS “kink,” combined with the MS turn-off, provides a valuable tool to measure GC ages and offers a promising opportunity to push the absolute age of GCs to sub-Gyr accuracy with the next generation IR telescopes such as the James Webb Space Telescope and the Wide-field Infrared Survey Telescope.
Production, economics and yield gap analysis of groundnut influenced by cluster front line demonstrations in Warangal district of Telangana

The Cluster frontline demonstrations (CFLDs) on groundnut were conducted by Krishi Vigyan Kendra, Mamnoor, Warangal during Rabi season of 2018-19 and 2019-2020 across an area of 97.2 ha with 157 demonstrations. Results revealed that per cent increase in demonstration yield over farmers practice was 18.7 and 24.24 during 2018-19 and 2019-20 respectively. Highest B: C ratio (2.61 and 3.16) was realized from demonstration during the study period against B: C ratio of 2.20 and 2.53 in farmers practice. During investigation, average technology gap (3.9 q/ha), average extension gap (3.7 q/ha) and technology index of 13.2% and 18.0% in respective years was recorded. Increased production and economic returns improved livelihood of farmers. The present study signifies that location specific recommendations must be formulated to narrow down technology gap and encourage beneficiary farmers to adopt full demonstrated technology to lessen extension gap. The technology index warrants horizontal spread.
JOB ACCOMPLISHMENT THROUGH INFORMATION TECHNOLOGY COMPETENCIES AND CORPORATE SOCIAL MEDIA USAGE OF COMPANY EMPLOYEES IN INDONESIA

This research aimed to examine the factors that could affect the distribution of jobs accomplishment, which was included the distribution of corporate social media, information technologies competencies, and jobs interconnections. This research used the partial least square-structural equation model (PLS-SEM) to test the proposed hypothesis. Participants in this study included 367 respondents as the employees in Indonesia. The data collected in this research used a surveyed approached to get responses from participants. The results of data analysis in this research revealed that corporate social media had a significant direct effect on jobs accomplishment and jobs interconnections. In addition, the information technologies competencies had also showed to have an essential direct role in jobs accomplishment and jobs interconnections. Jobs interconnections had also showed to have a significant direct influence on jobs accomplishment. This study proved that jobs interconnections had a significant mediating effect on the relationship between corporate social media and jobs accomplishment, but it had no influencers the relationship between information technologies competencies and jobs accomplishment.
Effect of surfactant concentration and interfacial slip on the flow past a viscous drop at low surface Péclet number

The motion of a viscous drop is investigated when the interface is fully covered with a stagnant layer of surfactant in an arbitrary unsteady Stokes flow for the low surface P\'eclet number limit. The effect of the interfacial slip coefficient on the behavior of the flow field is also considered. The hydrodynamic problem is solved by the solenoidal decomposition method and the drag force is computed in terms of Faxen's laws using a perturbation ansatz in powers of the surface P\'eclet number. The analytical expressions for the migration velocity of the drop are also obtained in powers of the surface P\'eclet number. Further instances corresponding to a given ambient flow as uniform flow, Couette flow, Poiseuille flow are analyzed. Moreover, it is observed that, a surfactant-induced cross-stream migration of the drop occur towards the centre-line in both Couette flow and Poiseuille flow cases. The variation of the drag force and migration velocity is computed for different parameters such as P\'eclet number, Marangoni number etc.
Cheminformatics Identification and Validation of Dipeptidyl Peptidase-IV Modulators from Shikimate Pathway-Derived Phenolic Acids towards Interventive Type-2 Diabetes Therapy

Recently, dipeptidyl peptidase-IV (DPP-IV) has become an effective target in the management of type-2 diabetes mellitus (T2D). The study aimed to determine the efficacy of shikimate pathway-derived phenolic acids as potential DPP-IV modulators in the management of T2D. The study explored in silico (molecular docking and dynamics simulations) and in vitro (DPP-IV inhibitory and kinetics assays) approaches. Molecular docking findings revealed chlorogenic acid (CA) among the examined 22 phenolic acids with the highest negative binding energy (−9.0 kcal/mol) showing a greater affinity for DPP-IV relative to the standard, Diprotin A (−6.6 kcal/mol). The result was corroborated by MD simulation where it had a higher affinity (−27.58 kcal/mol) forming a more stable complex with DPP-IV than Diprotin A (−12.68 kcal/mol). These findings were consistent with in vitro investigation where it uncompetitively inhibited DPP-IV having a lower IC50 (0.3 mg/mL) compared to Diprotin A (0.5 mg/mL). While CA showed promising results as a DPP-IV inhibitor, the findings from the study highlighted the significance of medicinal plants particularly shikimate-derived phenolic compounds as potential alternatives to synthetic drugs in the effective management of T2DM. Further studies, such as derivatisation for enhanced activity and in vivo evaluation are suggested to realize its full potential in T2D therapy.
Monetary Policy in Japan Since the Late 1980s: Delayed Policy Actions and Some Explanations

Japan’s monetary policy is now at a crossroads. The overnight call rate, the primary instrument of monetary policy in Japan, had been virtually zero for almost a year at the time of this writing (February 2000). There are increasing requests for further monetary easing, from both inside and outside the country, to prompt economic recovery. The requests often come with the proposal that the central bank should purchase some specific assets, such as government bonds, stocks, foreign currencies (implying unsterilized intervention), or even real estate. These proposals are in some cases accompanied by the policy strategy of ‘‘managed inflation,’’ in which the central bank makes an exclusive commitment to achieve some targeted inflation, or, more broadly, ‘‘inflation targeting. ’’ In contemplating further policy actions, it may be worthwhile to look back at the history of Japan’s monetary policy and seek to draw some lessons from the past. This essay reviews how monetary policy has func-
TECHNICAL-TACTICAL ANALYSIS OF MEN’S WRESTLING: A CASE STUDY OF THE 72ND NATIONAL ATHLETIC MEET OF 2017 IN JAPAN

The purpose of this research was to reveal the techniques that winners and losers attempted to use in wrestling matches, as well as the number of times these techniques were successful. We filmed and categorized the techniques used in 19 freestyle and 10 Greco-Roman matches in the 72nd National Athletic Meet of 2017 in Japan. When the winner scored points, standing position accounted for a high proportion of the positions in both freestyle and Greco-Roman, at 71.1% and 66.7% respectively. The loser scored all the points in the standing position. These results indicate that wrestling matches play out with a focus on standing positions. In freestyle, single-leg attacks were the most common point-scoring techniques for winners and the second most common for losers. The success rate for single-leg attack by winners was 73.1% but was significantly lower for losers at 25.0%. Therefore, it can be considered that practice on improving the success rate of single-leg attacks should be prioritized for securing victory in freestyle. The technique that scored the most points for winners in Greco-Roman was the gut wrench. Conversely, the gut wrench was not present and therefore failed to score points for the losers. These findings can be helpful to plan effective training for wrestlers.
Clustering of intermediate redshift quasars using the final SDSS III-BOSS sample

Author(s): Eftekharzadeh, S; Myers, AD; White, M; Weinberg, DH; Schneider, DP; Shen, Y; Font-Ribera, A; Ross, NP; Paris, I; Streblyanska, A | Abstract: © 2015 The Authors. Published by Oxford University Press on behalf of the Royal Astronomical Society. We measure the two-point clustering of spectroscopically confirmed quasars from the final sample of the Baryon Oscillation Spectroscopic Survey (BOSS) on comoving scales of 4 ≲ s ≲ 22 h-1 Mpc. The sample covers 6950 deg2 [~19 (h-1Gpc)3] and, over the redshift range 2.2 ≲ z ≲ 2.8, contains 55 826 homogeneously selected quasars, which is twice as many as in any similar work. We deduce bQ = 3.54 ± 0.10; the most precise measurement of quasar bias to date at these redshifts. This corresponds to a host halo mass of ~2 × 1012 h-1M⊙ with an implied quasar duty cycle of ~1 per cent. The real-space projected correlation function is well fitted by a power law of index 2 and correlation length r0 = (8.12 ± 0.22) h-1 Mpc over scales of 4 ≲ rp ≲ 25 h-1 Mpc. To better study the evolution of quasar clustering at moderate redshift, we extend the redshift range of our study to z ~ 3.4 and measure the bias and correlation length of three subsamples over 2.2 ≲ z ≲ 3.4. We find no significant evolution of r0 or bias over this range, implying that the host halo mass of quasars decreases somewhat with increasing redshift. We find quasar clustering remains similar over a decade in luminosity, contradicting a scenario in which quasar luminosity is monotonically related to halo mass at z ≈ 2.5. Our results are broadly consistent with previous BOSS measurements, but they yield more precise constraints based upon a larger and more uniform data set.
Influence of hadronic bound states above T c on heavy-quark observables in Pb + Pb collisions at the CERN Large Hadron Collider

We investigate how the possible existence of hadronic bound states above the deconfinement transition temperature ${T}_{c}$ affects heavy-quark observables, such as the nuclear modification factor, the elliptic flow, and azimuthal correlations. Lattice QCD calculations suggest that above ${T}_{c}$ the effective degrees of freedom might not be exclusively partonic but that a certain fraction of hadronic degrees of freedom might already form at higher temperatures. This is an interesting question by itself but also has a strong influence on other probes of the strongly interacting matter produced in ultrarelativistic heavy-ion collisions. A substantial fraction of hadronic bound states above ${T}_{c}$ reduces on average the interaction of the heavy quarks with colored constituents of the medium. We find that all studied observables are highly sensitive to the active degrees of freedom in the quark-gluon plasma.
A New Back Casting Method for Valuing Urban Land: Comparison to Land Residuals*

We develop a new method for urban land valuation based on theory which implies that land and structure trade as a bundle until the structure has no economic value. This back casting method first estimates property value, construction costs and residual land value in the year of new construction. Thereafter, the ratio of land to property value changes primarily with structure depreciation; changes in property value are shared by land and structure components. In contrast, land residual methods (land value equals property value minus the depreciated cost to rebuild in the sales year) predicts that the ratio is volatile because it is leveraged by relatively stable replacement costs. We fit both models to Maricopa County assessor data on houses up to 28 years old during a bust and recovery period (2007–2018) and we evaluate the models for relevance to property tax assessment. Our inability to distinguish from a counterfactual points towards future research focused on sample selection. *We are grateful to the Lincoln Institute of Land Policy for data and financial support. We benefitted from conversations and data provided by Jeffrey P. Cohen, John Harding, Jennifer Rearich and Kerry Vandell, and from extensive discussion with participants in a Lincoln Institute symposium, January 2021.
Heavy quarkonium production: Nontrivial transition from pA to AA collisions

Two novel QCD effects, double-color filtering and mutual boosting of the saturation scales in colliding nuclei, affect the transparency of the nuclei for quark dipoles in comparison with proton-nucleus collisions. The former effect increases the survival probability of the dipoles, since color filtering in one nucleus makes the other one more transparent. The second effect acts in the opposite direction and is stronger; it makes the colliding nuclei more opaque than in the case of pA collisions. As a result of parton saturation in nuclei the effective scale is shifted upward, which leads to an increase of the gluon density at small x. This in turn leads to a stronger transverse momentum broadening in AA compared with pA collisions, i.e., to an additional growth of the saturation momentum. Such a mutual boosting leads to a system of reciprocity equations, which result in a saturation scale, a few times higher in AA than in pA collisions at the energies of the large hadron collider (LHC). Since the dipole cross section is proportional to the saturation momentum squared, the nuclei become much more opaque for dipoles in AA than in pA collisions. For the same reason gluon shadowing turns out to bemore » boosted to a larger magnitude compared with the product of the gluon shadowing factors in each of the colliding nuclei. All these effects make it more difficult to establish a baseline for anomalous J/{Psi} suppression in heavy ion collisions at high energies. « less
Brucella Infection in Domestic Animals in Nigeria: A Review

et al. Brucella 5(1): 1099. Abstract Brucellosis of animal origin is currently in the increase, especially in the developing countries like Nigeria where an imals and man share microenvironment together coupled with lack of proper control measures. The disease due to Brucella species has zoonotic implication and is responsible for high economic loss. Brucella spp. infects many animals’ species and their prevalence is worldwide, mainly associ ated with the presence or absence of control programmes and also in some countries, with the vaccination of animals against the disease. It is eradicated through prevention, sur veillance and test-and-slaughter programmes in animals by many developed countries. To control and eradicate brucel losis, it is pertinent to identify the risk factors of the dis ease in animals and/or the environment that maintain such infections. Several risks have been identified; the most im portant have been identified as animal management (age, sex, species or breed), herd management (herd/flock size, number of species, contact with wild animals or type of ani mal production), farm management (facilities, cleaning and disinfection or veterinary support) and farmers’ knowledge about the disease. All these have been poorly studied and reported in Nigeria, leading to scanty of information for ef fective implementation of eradication, prevention and con trol programmes. The objective of this manuscript was to review the work of earlier workers on Brucellosis in domes tic animals and to a certain extent its impact on humans. There is also the need to educate the populace on the dan-gers of the disease in both human and animals.
