description: Nonsequential multiple ionization of atoms in intense laser fields is initiated by a recollision between an electron, freed by tunneling, and its parent ion. Following recollision, the initial electron shares its energy with several bound electrons. We use a classical model based on rapid electron thermalization to interpret recent experiments. For neon, good agreement with the available data is obtained with an upper bound of 460 attoseconds for the thermalization time.

description: The autocorrelation function (ACF) is a simple and useful tool that allows to measure the average linewidth of spectra with great precision. Unlike the cross-correlation function (CCF), the ACF can be used without having to rely on weighted binary masks. It makes the ACF much easier to use. We analyze 7 Cepheids and present a new method to obtain very precise turbulent velocity curves for 6 of them by using the ACF. We compare our Full Widths at Half-Maximum (FWHM) curves as a function of the pulsational phase to those of Nardetto et al. (2006) who used the Fe I 6056.005 Å line only. We note a significant improvement in the shape of the FWHM curves for all Cepheids by using the ACF. From the FWHM curves, we measure microturbulence curves for 6 Cepheids by using a Gaussian approximation. Finally, we artificially degrade the resolution of the spectra and add noise to further assess and highlight the advantages of the ACF. The FWHM curves obtained with the ACF remain virtually unchanged up to a degradation by a factor of 10. A degradation by a factor of 20 slightly affected the results but an average linewidth variation remains easily detectable.

description: Introduction: Today mental disorders are important concerns of health care system in all countries. Among different mental disorders; depression, anxiety, and somatization are more frequent. This manuscript was conducted to evaluate the frequency of somatization symptoms, its related factors and the correlation between somatization symptoms and anxiety and depression disorders in Iranian population. Methods: The cross-sectional study was conducted in Kerman, Iran, 2017. Participants were selected from patients who referred to the Clinics of Educational Hospitals using convenience sampling method. The PHQ-15 and HADS questionnaire were used to assess the somatization and depression and anxiety, respectively. The univariate and multivariate logistic regression was used to determine the predictive factors of somatization symptoms. The correlations between each PHQ-15 item score and anxiety and depression score were expressed. Results: The frequency of mild, moderate and severe levels of somatization was 66.3%, 20.5% and 13.1%, respectively. Considering multivariate logistic regression analysis; age was associated with somatic symptoms, significantly. The risk of somatic symptoms was 3.4 times more in Divorced/Widowed participants than single ones (p-value: 0.035). There were significant positive correlations between anxiety and depression scores. Each additional score of anxiety and depression were associated with 1.14 times more likely (p-value: <0.001) and 1.11 times less likely (p-value: 0.003) of having somatic symptoms, respectively. Conclusion: The burden of somatization, depression and anxiety is high in Iranian population. Psychologists and policy-makers should consider these predictive factors for primary prevention of somatization at the personal and community level, respectively.

description: The coverage of vicinal, stepped surfaces with molecules is simulated with the help of a two-dimensional Ising model including local distortions and an Ehrlich-Schwoebel barrier term at the steps. An effective two-spin model is capable to describe the main properties of this distorted Ising model. It is employed to analyze the behavior of the system close to the critical points. Within a well-defined regime of bonding strengths and Ehrlich-Schwoebel barriers we find a reduction of coverage (magnetization) at low temperatures due to the presence of the surface step. This results in a second, low-temperature transition besides the standard Ising order-disorder transition. The additional transition is characterized by a divergence of the susceptibility as a finite-size effect. Due to the surface step the mean-field specific heat diverges with a power law.

description: The World Wide Web's introduction and the quick uptake of social media sites like Facebook and Twitter opened the door to a level of information sharing never seen in human history. Social media platforms are being used by consumers to create and share more information than ever before, some of it false and unrelated to reality. It is difficult to automatically classify a text article as misleading or disinformation. Even a subject-matter expert must consider a variety of factors before determining if an article is true. In this work, we propose to automatically classify news articles using an ensemble machine learning approach. Our research examines many textual characteristics that can be utilized to discern authentic content from counterfeit. We train a variety of machine learning algorithms employing those properties in conjunction with different ensemble approaches, and we assess their performance on four real-world datasets. Our suggested ensemble learner technique outperforms individual learners, as confirmed by experimental evaluation.

Publisher: name: Journal of Preventive Medicine and Hygiene
Year: 2019

description: Introduction: The health benefits of physical activity in all ages are widely known, however the effects of early physical activity on future health are not yet fully understood. The aim of this study was to analyze the cross-sectional associations between previous and current physical activity with overweight among adults. Methods: A probabilistic sample of 534 teachers was included in the study. Independent variables were physical activity in childhood, adolescence, and current, and clustering of physical activity through life, all analyzed using a self-report questionnaire. The dependent variable was overweight, estimated by the body mass index, assessed using self-report measures of weight and height. Covariates were sex, age, skin color, income, sedentary behavior, medication use for weight control, and nutritionist counseling. Poisson regression was adopted to estimate Prevalence Ratios (PR) in the multivariate analysis. Results: Physical activity at ages 6-10 (PR=1.03 to 1.13), 12-14 (PR=0.96 to 0.98), and 15-17 (PR=0.76 to 0.90) years was not associated with overweight. Participants who do not meet the recommendation of current physical activity have a higher likelihood of being overweight (PR=1.55 to 2.17) and the magnitude of the association increased when analyzing those who were not physically active through all stages of life (PR=3.69 to 4.69). Conclusion: Performing physical activity only in early life does not seem to promote health benefits in the sample analyzed. Although current physical activity is associated with the outcome, promoting physical activity continuously through lifespan seems to be a better strategy to prevent overweight among adults.

description: Extracellular vesicles (EVs) are released from cells and enter into body fluids thereby providing a toxicological mechanism of cell-cell communication. The present study aimed at assessing (a) the presence of EVs in mouse body fluids under physiological conditions, (b) the effect of exposure of mice to cigarette smoke for 8 weeks, and (c) modulation of smoke-related alterations by the nonsteroidal anti-inflammatory drug celecoxib, a selective cyclooxygenase-2 inhibitor. To this purpose, ICR (CD-1) mice were either unexposed or exposed to cigarette smoke, either treated or untreated with oral celecoxib. EVs, isolated from bronchoalveolar lavage fluid (BALF), blood serum, and urines, were analyzed by nanoparticle tracking analysis and flow cytometry. EVs baseline concentrations in BALF were remarkably high. Larger EVs were detected in urines. Smoking increased EVs concentrations but only in BALF. Celecoxib remarkably increased EVs concentrations in the blood serum of both male and female smoking mice. The concentration of EVs positive for EpCAM, a mediator of cell-cell adhesion in epithelia playing a role in tumorigenesis, was much higher in urines than in BALF, and celecoxib significantly decreased their concentration. Thus, the effects of smoke on EVs concentrations were well detectable in the extracellular environment of the respiratory tract, where they could behave as delivery carriers to target cells. Celecoxib exerted both protective mechanisms in the urinary tract and adverse systemic effects of likely hepatotoxic origin in smoke-exposed mice. Detection of EVs in body fluids may provide an early diagnostic tool and an end-point exploitable for preventive medicine strategies.

description: The electronic transport properties of the delafossite oxides ABO$_2$ are usually understood in terms of two well separated entities, namely, the triangular A$^+$ and (BO$_2$)$^-$ layers. Here we review several cases among this extensive family of materials where the transport depends on the interlayer coupling and displays unconventional properties. We review the doped thermoelectrics based on CuRhO$_2$ and CuCrO$_2$, which show a high-temperature recovery of Fermi-liquid transport exponents, as well as the highly anisotropic metals PdCoO$_2$, PtCoO$_2$ and PdCrO$_2$ where the sheer simplicity of the Fermi surface leads to unconventional transport. We present some of the theoretical tools that have been used to investigate these transport properties and review what can and cannot be learned from the extensive set of electronic structure calculations that have been performed.

description: We exhibit string contributions to the $\nd{S}$ matrix relating in- and out- state density matrices that do not factorize as a product of $S$ and $S^\dagger$ matrices. They are associated with valley trajectories between topological defects on the string world sheet, that appear as quantum fluctuations in the space-time foam. Through their ultraviolet cut-off dependences these valleys cause non-Hamiltonian time evolution and suppress off-diagonal entries in the density matrix at large times.

description: One of the most active fields of research of modern-day astrophysics is that of massive black hole formation and co-evolution with the host galaxy. In these investigations, ranging from cosmological simulations, to semi-analytical modeling, to observational studies, the Bondi solution for accretion on a central point mass is widely adopted. In this work we generalize the classical Bondi accretion theory to take into account the effects of the gravitational potential of the host galaxy, and of radiation pressure in the optically thin limit. Then, we present the fully analytical solution, in terms of the Lambert-Euler $W$-function, for isothermal accretion in Jaffe and Hernquist galaxies with a central black hole. The flow structure is found to be sensitive to the shape of the mass profile of the host galaxy. These results and the formulae that are provided, mostly important the one for the critical accretion parameter, allow for a direct evaluation of all flow properties, and are then useful for the above mentioned studies. As an application, we examine the departure from the true mass accretion rate of estimates obtained using the gas properties at various distances from the black hole, under the hypothesis of classical Bondi accretion. An overestimate is obtained from regions close to the black hole, and an underestimate outside a few Bondi radii; the exact position of the transition between the two kinds of departure depends on the galaxy model.

description: We report on the spectral analysis of the peculiar source Cir X-1 observed by the BeppoSAX satellite when the X-ray source was near the periastron. A flare lasting $\sim 6 \times 10^3$ s is present at the beginning of the observation. The luminosity during the persistent emission is $1 \times 10^{38}$ erg s$^{-1}$, while during the flare is $2 \times 10^{38}$ erg s$^{-1}$. We produced broad band (0.1-100 keV) energy spectra during the flare and the persistent emission. At low energies the continuum is well fitted by a model consisting of Comptonization of soft photons, with a temperature of $\sim 0.4$ keV, by electrons at a temperature of $\sim 1$ keV. Out of the flare a power-law component, with photon index $\sim 3$, is dominant at energies higher than 10 keV. This component contributes to $\sim 4%$ of the total luminosity. During the flare its addition is not statistically significant. An absorption edge at $\sim 8.4$ keV, with optical depth $\sim 1$, corresponding to the K-edge of Fe XXIII-XXV, and an iron emission line at 6.7 keV are also present. The iron line energy is in agreement with the ionization level of the absorption edge. The hydrogen column deduced from the absorption edge is $\sim 10^{24}$ cm$^{-2}$, two order of magnitude larger than the absorption measured in this source. We calculated the radius of the region originating the comptonized seed photons, $R_W \sim 150$ km. We propose a scenario where $R_W$ is the inner disk radius, a highly ionized torus surrounds the accretion disk and a magnetosphere is large up to $R_W$. The absorption edge and the emission line could originate in the photoionized torus, while the comptonized component originates in an inner region of the disk.

description: Introduction: Tuberculosis (TB) is a major public health problem in most of developing countries. Meanwhile, the prevalence of type 2 diabetes mellitus (DM) is also increasing rapidly. Objectives: To describe the feasibility of implementing screening test for tuberculosis among diabetic patients and identifying factors associated with high detection rate. Methods: Study Design: Multi-center cross-sectional study. This study was implemented in the governmental healthcare settings. To diagnose TB among diabetics, we used a symptom-based questionnaire that included the symptoms of suspected TB according to the guidelines of National Tuberculosis Program in Egypt. Results: Among 4283 adult diabetics, 14 TB cases were diagnosed; 9 known TB cases and 5 newly detected cases. The number needed to detect one new case of TB was 855. Male diabetics and those suffered from liver disease experienced a significantly higher prevalence of TB and a higher detection rate of new active cases. Conclusions: Screening for TB among diabetics in routine governmental healthcare services was successfully implemented. Screening DM patients in countries with a high prevalence of DM will reveal a significant number of active TB cases, which will in turn improve the case detection rate of TB.

Rayleigh-Taylor stability of a strong vertical magnetic field at the Galactic center confined by a disk threaded with horizontal magnetic field

description: Observations of narrow radio-emitting filaments near the Galactic center have been interpreted in previous studies as evidence of a pervasive vertical (i.e. perpendicular to the Galactic plane) milliGauss magnetic field in the central 150 pc of the Galaxy. A simple cylindrically symmetric model for the equilibrium in this central region is proposed in which horizontal (i.e. parallel to the Galactic plane) magnetic fields embedded in an annular band of partially ionized molecular material of radius 150 pc are wrapped around vertical magnetic fields threading low-density hot plasma. The central vertical magnetic field, which has a pressure that significantly exceeds the thermal pressure of the medium, is confined by the weight of the molecular material. The stability of this equilibrium is studied indirectly by analyzing a uniformly rotating cylinder of infinite extent along the z axis in cylindrical coordinates (r,theta,z), with low-density plasma and an axial magnetic field at r< 150 pc, high-density plasma and an azimuthal field at r> 150 pc, and a gravitational acceleration g* proportional to r directed in the negative-r-hat direction. The density profile and gravity tend to destabilize the plasma, but the plasma tends to be stabilized by rotation and magnetic tension--since the interface between the high and low-density plasmas can not be perturbed without bending either the horizontal or vertical field. It is shown analytically that when beta= 8(pi)p/B^2 is small and the dense plasma is supported against gravity primarily by rotation, the necessary and sufficient condition for stability to k_z=0 modes is |g| < (2|Omega| a), where g = g* - Omega^2 r is the effective gravity, Omega is the uniform angular velocity, and "a" is the sound speed in the dense plasma.

description: India's tourism sector has the potential to accelerate economic and social development and transform economies. Rajasthan, known for its Thar Desert, has seen a fourfold increase in tourist arrivals in the last thirty years, attracting tourists from various states and the world. The state is home to several major tourist circuits and locations, each with its own unique attractions. The future of tourism in Rajasthan depends on partnerships between government agencies and the private sector. As tourist numbers increase, Rajasthan needs more hotel rooms to meet demand. The state has developed an ambitious plan to grow the tourism industry and improve visitor experience, including efforts to rehabilitate infrastructure, restore existing sites, and develop new tourism circuits and products. Private investment opportunities have emerged, such as buying private heritage assets, managing RTDC properties on lease or joint ventures, and investing in amusement parks, theme parks, resorts, adventure tourism, andNaturopathy, yoga, and meditation centers. However, the corporation's contribution to providing lodging to visitors was minimal, with a decrease in occupancy in hotels/motels due to insufficient advertising, insufficient marketing, and an unsuccessful marketing plan.

description: In this paper we consider the following Cauchy problem for the semi-linear wave equation with scale-invariant dissipation and mass and power non-linearity: \begin{align}\label{CP abstract} \begin{cases} u_{tt}-Δu+\dfrac{μ_1}{1+t} u_t+\dfrac{μ_2^2}{(1+t)^2}u=|u|^p, \\ u(0,x)=u_0(x), \,\, u_t(0,x)=u_1(x), \end{cases}\tag{$\star$} \end{align} where $μ_1, μ_2^2$ are nonnegative constants and $p>1$. On the one hand we will prove a global (in time) existence result for \eqref{CP abstract} under suitable assumptions on the coefficients $μ_1, μ_2^2$ of the damping and the mass term and on the exponent $p$, assuming the smallness of data in exponentially weighted energy spaces. On the other hand a blow-up result for \eqref{CP abstract} is proved for values of $p$ below a certain threshold, provided that the data satisfy some integral sign conditions. Combining these results we find the critical exponent for \eqref{CP abstract} in all space dimensions under certain assumptions on $μ_1$ and $μ_2^2$. Moreover, since the global existence result is based on a contradiction argument, it will be shown firstly a local (in time) existence result.

description: For the modelling of pedestrian dynamics we treat persons as self-driven objects moving in a continuous space. On the basis of a modified social force model we qualitatively analyze the influence of various approaches for the interaction between the pedestrians on the resulting velocity-density relation. To focus on the role of the required space and remote force we choose a one-dimensional model for this investigation. For those densities, where in two dimensions also passing is no longer possible and the mean value of the velocity depends primarily on the interaction, we obtain the following result: If the model increases the required space of a person with increasing current velocity, the reproduction of the typical form of the fundamental diagram is possible. Furthermore we demonstrate the influence of the remote force on the velocity-density relation.

Hořava-Lifshitz Bouncing Bianchi IX Universes: A Dynamical System Analysis

description: We examine the Hamiltonian dynamics of bouncing Bianchi IX cosmologies in Hořava-Lifshitz gravity. The $6$-dim phase space presents two critical points, one asymptotic de Sitter attractor at infinity and a $2$-dim invariant plane. We identified four distinct parameter domains $A$, $B$, $C$ and $D$ for which the pair of critical points engenders distinct features in the dynamics. In the domain $A$ the dynamics consists basically of periodic bouncing orbits, or oscillatory orbits with a finite number of bounces. The center with multiplicity two engenders in its neighborhood the topology of stable and unstable cylinders $R \times S^3$ of orbits. We show that the stable and unstable cylinders coalesce realizing a smooth homoclinic connection to the center manifold, a rare event of regular/non-chaotic dynamics in bouncing Bianchi IX cosmologies. The presence of a saddle of multiplicity two in the domain $B$ engenders a high instability in the dynamics so that the cylinders emerging from the center manifold towards the bounce have four distinct attractors: the center manifold itself, the de Sitter attractor at infinity and two further momentum-dominated attractors with infinite anisotropy. In the domain $C$ we examine the features of invariant manifolds of orbits about a saddle of multiplicity two. The presence of the saddle of multiplicity two engenders bifurcations of the invariant manifold as the energy $E_0$ of the system increases relative to the energy $E_{cr}$ providing structures that were not yet observed in the literature. The domain $D$ is not examined as most of its features are present already in the previous domains.

description: We propose a new stage of confiment-decofinment transition, which can be observed in laboratory. In two-gap superconductors (SCs), two kinds of vortex exist and each of them carries a continuously variable fraction of the unit flux quanta Phi_0=h c / 2 e. The confined state of these two is a usual vortex and stable in the low temperature region of the system under a certain magnetic field above H_c1. We see an analogy to quarks in a charged pion. An entropy gain causes two fractional vortices to be deconfined above a certain temperature.

Classical dynamics of rigid string from Willmore functional

description: A new approach for investigating the classical dynamics of the relativistic string model with rigidity is proposed. It is based on the embedding of the string world surface into the space of a constant curvature. It is shown that the rigid string in flat space-time is described by the Euler-Lagrange equation for the Willmore functional in a space-time of the constant curvature K=-g/(2 a), where g and a are constants in front of the Nambu-Goto term and the curvature term in the rigid string action respectively. For simplicity the Euclidean version of the rigid string in the three-dimensional space-time is considered. The Willmore functional (the action for the "Willmore string") is obtained by dropping the Nambu-Goto term in the Polyakov-Kleinert action for the rigid string. Such "reduction" of the rigid string model would be useful, for example, by applying some results about the Numbu-Goto string dynamics in the de Sitter universe to the rigid string model in the Minkowski space-time. It allows also to use numerous mathematical results about the Willmore surfaces in the context of the physical problem.

description: The detailed distribution and kinematics of the atomic and the CO-bright molecular hydrogen in the disc of the Milky Way inside the Solar circle are derived under the assumptions of axisymmetry and pure circular motions. We divide the Galactic disc into a series of rings, and assume that the gas in each ring is described by four parameters: its rotation velocity, velocity dispersion, midplane density and its scale height. We fit these parameters to the Galactic HI and CO (J=1-0) data by producing artificial HI and CO line-profiles and comparing them with the observations. Our approach allows us to fit all parameters to the data simultaneously without assuming a-priori a radial profile for one of the parameters. We present the distribution and kinematics of the HI and H2 in both the approaching (QIV) and the receding (QI) regions of the Galaxy. Our best-fit models reproduces remarkably well the observed HI and CO longitude-velocity diagrams up to a few degrees of distance from the midplane. With the exception of the innermost 2.5 kpc, QI and QIV show very similar kinematics. The rotation curves traced by the HI and H2 follow closely each other, flattening beyond R=6.5 kpc. Both the HI and the H2 surface densities show a) a deep depression at 0.5

Gravitational Stirring in Planetary Debris Disks

Publisher: name: arXiv

description: We describe gravitational stirring models of planetary debris disks using a new multi-annulus planetesimal evolution code. The current code includes gravitational stirring and dynamical friction; future studies will include coagulation, fragmentation, Poynting-Robertson drag, and other physical processes. We use the results of our calculations to investigate the physical conditions required for small bodies in a planetesimal disk to reach the shattering velocity and begin a collisional cascade. Our results demonstrate that disks composed primarily of bodies with a single size will not undergo a collisional cascade which produces small dust grains at 30-150 AU on timescales of 1 Gyr or smaller. Disks with a size distribution of bodies reach conditions necessary for a collisional cascade in 10 Myr to 1 Gyr if the disk is at least as massive as a minimum mass solar nebula and if the disk contains objects with radii of 500 km or larger. The estimated 500 Myr survival time for these disks is close to the median age of roughly 400 Myr derived for nearby stars with dusty disks.

description: We study the ground state ordering and interactions between two two-dimensional Wigner crystals on neutralizing charged plates by means of computer simulation. We consider crystals formed by (i) point-like charges and (ii) charged dimers, which mimic the screening of charged surfaces by elongated multivalent ions such as aspherical globular proteins, charged dendrimers or short stiff polyelectrolytes. Both systems, with point-like and dimeric ions, display five distinct crystalline phases on increasing the interlayer distance. In addition to alteration of translational ordering within the bilayer, the phase transitions in the dimeric system are characterized by alteration of orientational ordering of the ions.

#Halal Culture on Instagram

description: Halal is a notion that applies to both objects and actions, and means permissible according to Islamic law. It may be most often associated with food and the rules of selecting, slaughtering, and cooking animals. In the globalized world, halal can be found in street corners of New York and beauty shops of Manila. In this study, we explore the cultural diversity of the concept, as revealed through social media, and specifically the way it is expressed by different populations around the world, and how it relates to their perception of (i) religious and (ii) governmental authority, and (iii) personal health. Here, we analyze two Instagram datasets, using Halal in Arabic (325,665 posts) and in English (1,004,445 posts), which provide a global view of major Muslim populations around the world. We find a great variety in the use of halal within Arabic, English, and Indonesian-speaking populations, with animal trade emphasized in first (making up 61% of the language's stream), food in second (80%), and cosmetics and supplements in third (70%). The commercialization of the term halal is a powerful signal of its detraction from its traditional roots. We find a complex social engagement around posts mentioning religious terms, such that when a food-related post is accompanied by a religious term, it on average gets more likes in English and Indonesian, but not in Arabic, indicating a potential shift out of its traditional moral framing.

description: We have witnessed a dramatic increase over the last five years in results on distant galaxies, in large part because of the high resolution imaging capability of HST, and the multiobject spectroscopic capability of the Keck telescopes. Our program to obtain wide-field, multi-color WFPC2 mosaics with HST of intermediate redshift clusters, and spectroscopic membership and high S/N spectroscopy with LRIS on Keck, has provided new insights into the nature of elliptical and S0 galaxies in the cluster environment over a wide range of densities. In particular, most ellipticals, and a significant fraction of the S0 population, have large luminosity-weighted ages, suggesting that their stellar populations were formed at redshifts beyond z~2, though the existence of substantial numbers of major mergers in MS 1054-03 at z=0.83 suggests that final assembly of such galaxies may not have occurred until much later for a significant fraction of early-type galaxies.

description: AbstractThe importance of continued development of petro-technical professionals in the upstream oil and gas industry cannot be over emphasized. The deep knowledge-base of upstream geoscience and engineering operations, coupled with its attendant long learning curve, the continued awareness and appreciation of health, safety and environment considerations in upstream operations, and the global talent crisis among petro-technical professionals requires that petro-technical professionals are provided with a structured, consistent and relevant training programs to develop their capacity to accelerate the time to autonomy. The main aim of the research study was to develop a competency framework to help develop human capital to accelerate time to autonomy for petro-technical professionals in the upstream oil and gas industry. The research study employed a pragmatism paradigmatic approach to the inquiry and adopted the mixed-methods exploratory sequential design. Qualitative data consisting of individual in-depth interviews were collected from 13 individuals: two CEOs or corporate leaders, three human resources or learning and development professionals, five petro-technical managers and three petro-technical professionals. Following analysis of these data, a survey was constructed and then distributed to 152 petro-technical professionals. The findings of the study contribute to theory development and practice by demonstrating that developing petro-technical professionals to accelerate time to autonomy requires a competency framework with an eclectic approach to training and development, utilizing a blended learning system to provide the employee with holistic training. The findings of the study also indicate that the competency framework must guide learning from the known to the unknown, simple to complex and concrete to abstract, adding new knowledge in an incremental manner. Finally, the study emphasizes that the competency framework must include critical developmental elements such as coaching and mentoring, career planning and progression systems, a goal-oriented performance management system with a two-way feedback mechanism, and a comprehensive post training evaluation system.
