description: A calculation of the high-harmonic generation (HHG) in $α$-quartz using the time-dependent density functional theory is reported. The inter-band process is attributed to the dominant in HHG above the band gap. The photon energy is set to 1.55 eV, and the cutoff energy of the plateau region is found to be limited at the 19th harmonic (30 eV). The dependence of the HHG efficiency at the cutoff energy region on laser intensity is consistent with that of the hole density in the lowest-lying valence band. Numerical results indicate that electron-hole recombination plays a crucial role in HHG in $α$-quartz. It is found that a 200 attosecond pulse train is produced using HHG around the plateau cutoff energy.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2007

description: Background: Annually, throughout the world, an estimated 271 million people suffer from work related injuries, and 2 million die from the injury. In recent years, in developed countries the occupational health and safety of workers has improved, but it is not true in developing countries. Ethiopia is categorized among under developed countries and do not have much data on health and safety. Objective: The objective of the study was to assess the knowledge and practice of factory workers on occupational safety information. Methods: A descriptive cross- sectional study was conducted in Kality Metal Product and Ethiopian Iron and Steel factories in March 2007. A total of 417 study subjects were randomly selected from the two factories according to their worker number proportions. The data was collected using the questionnaires, focus group discussion, and observational checklists. The questionnaire was pre-tested for their accuracy and validation prior to the actual study and the necessary adjustments were done accordingly. The data were entered after being encoded and analyzed using Epi info and SPSS. Results: The mean (standard deviation) age of the respondents was 39.56± (11.08). Sixty nine percent of the respondents recognized at least one safety sign. Two hundred eighteen (52.3%) respondents got training on different occupational health and safety information and 71.5% of the respondents used glove and 48.2% used boots. Safety recommendation, sex, and work experience were found to be the determinant factors of respondents knowledge level [OR: 2.394(1.439, 3.984)], [OR: 2.398(1.169, 4.922)], and [OR: 1.934(1.178, 3.174)] respectively. Health and safety training was found to be a positive determinant factor for PPD usage [OR: 1.970(1.146, 3.386)]. Conclusion and recommendation: The workers have less knowledge level compared to other studies. Health and safety recommendations have positive effects on both knowledge levels and safe practices. Health and safety training has positive effects on safe practice but did not impact knowledge. Health and safety recommendation should be given to the workers. Safety signs should posted at a reasonable work sites. Keywords: occupational health and safety information,knowledge,practice

description: Exoplanet atmospheres are the key to understanding the nature of exoplanets. To this end, transit spectrophotometry provides us opportunities to investigate the physical properties and chemical compositions of exoplanet atmospheres. We aim to detect potential atmospheric signatures in 12 gaseous giant exoplanets using transit spectrophotometry and we try to constrain their atmospheric properties. The targets of interest were observed using transit spectrophotometry with the GTC OSIRIS instrument. We estimated the transit parameters and obtained the optical transmission spectra of the target planets using a Bayesian framework. We analyzed the spectral features in the transmission spectra based on atmospheric retrievals. Most of the observed transmission spectra were found to be featureless, with only the spectrum of CoRoT-1b showing strong evidence for atmospheric features. However, in combination with the previously published near-infrared transmission spectrum, we found multiple interpretations for the atmosphere of CoRoT-1b due to the lack of decisive evidence for alkali metals or optical absorbers. Featureless spectra are not necessarily indicative of cloudy atmospheres if they poorly constrain the altitudes of cloud decks. Precise constraints on the models of hazes and clouds strongly depend on the significance of the observed spectral features. Further investigations on these exoplanets, especially CoRoT-1b, are required to confirm the properties of their atmospheres.

description: Wide-field radio continuum observations of galaxy clusters are revealing an increasing number of spiral galaxies hosting tens of kpc-long radio tails produced by the nonthermal interstellar medium being displaced by the ram pressure. We present a semi-empirical model for the multi-frequency radio continuum emission from ram pressure stripped tails based on the pure synchrotron cooling of a radio plasma moving along the stripping direction with a uniform velocity. We combine LOFAR and uGMRT observations at 144 and 400 MHz to study the flux density and spectral index profiles of the radio tails of 7 galaxies in Abell 2255, and use the model to reproduce the flux density and spectral index profiles, and infer the stripped radio plasma velocity. For 5 out of 7 galaxies we observe monotonic decrease in both flux density and spectral index up to $~30$ kpc from their stellar disk. Our model reproduces the observed trends with a radio plasma bulk projected velocity between 160 and 430 km s$^{-1}$. This result represents the first indirect measure of the stripped, nonthermal interstellar medium velocity. The observed spectral index trends indicate that the synchrotron cooling is faster than the adiabatic expansion losses, thus suggesting that the stripped radio plasma can survive for a few tens of Myr outside of the stellar disk. This provides a lower limit for the lifetime of the stripped ISM outside of the disk. As a proof of concept, we use the best-fit velocities to constrain the galaxies' 3D velocity in the cluster to be in the 300-1300 km s$^{-1}$. We estimate the ram pressure affecting these galaxies to be between 0.1 and 2.9 $\times10^{-11}$ erg cm$^{-3}$, and measure the inclination between their stellar disk and the ram pressure wind.

description: We calculate the medium modification factor $I_{pA}$ for the photon-tagged jet fragmentation functions for scenario with the quark-gluon plasma formation in $pA$ and $pp$ collisions. We perform calculations of radiative and collisional parton energy loss in the quark-gluon plasma with running $α_s$ which has a plateau around $Q\sim κT$ with $κ$ fitted to the LHC data on the heavy ion $R_{AA}$. We find that the theoretical prediction for $I_{pA}$ in $5.02$ TeV $p$+Pb collisions are within errors consistent with the data from ALICE [1]. However, a definite conclusion about the presence or absence of jet quenching in $pA$ collisions cannot be drawn due to large experimental errors of the ALICE data [1]. Our calculations show that this requires a significantly more accurate measurement of $I_{pA}$.

description: The concept of weak invariant is introduced. Then, the weak invariants associated with time-dependent quantum dissipative systems are discussed in the context of master equations of the Lindblad type. In particular, with the help of the su(1,1) Lie-algebraic structure, the weak invariant is explicitly constructed for the quantum damped harmonic oscillator with the time-dependent frequency and friction coefficient. This generalizes the Lewis-Riesenfeld invariant to the case of nonunitary dynamics in the Markovian approximation.

description: We report the discovery of a candidate dual QSO at z=1.889, a redshift that is in the era known as "cosmic noon" where most of the Universe's black hole and stellar mass growth occurred. The source was identified in Hubble Space Telescope WFC3/IR images of a dust-reddened QSO that showed two closely-separated point sources at a projected distance of 0.26", or 2.2 kpc. This red QSO was targeted for imaging to explore whether red QSOs are hosted by merging galaxies. We subsequently obtained a spatially-resolved STIS spectrum of the system, covering the visible spectral range, and verifying the presence of two distinct QSO components. We also obtained high-resolution radio continuum observations with the VLBA at 1.4 GHz (21-cm L band) and found two sources coincident with the optical positions. The sources have similar black hole masses, bolometric luminosities, and radio loudness parameters. However, their colors and reddenings differ significantly. The redder QSO has a higher Eddington ratio, consistent with previous findings. We consider the possibility of gravitational lensing and and find that it would require extreme and unlikely conditions. If confirmed as a bona-fide dual QSO, this system would link dust-reddening to galaxy and supermassive black hole mergers, opening up a new population in which to search for samples of dual AGN.

description: Galactic halos accrete material from the intergalactic medium (IGM) and part of this accretion is expected to be in the form of cool ($T\sim10^4$ K) gas. A signature of this process could reside in the detection of numerous clouds in the circumgalactic medium (CGM). However, whether this material is able to accrete onto the galaxies and feed their star formation or, instead, evaporates into the CGM hot phase (corona, $T\sim10^6$ K), is not yet understood. Here, we investigate the evolution of cool CGM clouds accreted from the IGM and falling through the hot corona of low-redshift disc galaxies, using 3D high-resolution hydrodynamical simulations. We include the effects of gravity due to the dark matter halo, isotropic thermal conduction, radiative cooling and an ionizing UV background. We explored different values of parameters such as the halo mass, coronal mass, initial cloud velocity and strength of the thermal conduction. We find that the clouds lose the vast majority of their mass at distances larger than half of the galaxy virial radius and are completely dissolved in the corona before reaching the central galaxy. Resolving the Field length with at least 5-7 cells is crucial to correctly capture the evolution of the infalling cool gas. Our results indicate that cool IGM accretion can not feed star formation in $z\sim0$ star-forming galaxies in halos with masses of $10^{11.9}\ M_{\odot}$ or above. This suggests that present-day massive star-forming galaxies can sustain their star formation only via the spontaneous or induced cooling of their hot corona.

description: Context. Three-dimensional non-local thermodynamical equilibrium (NLTE) radiative transfer calculations are a fundamental tool for a detailed spectral analysis in stellar atmospheres, but require vast amounts of computer power. This prevents their broader application. Aims. We undertake a first exploration of the use of 3D irregular grids in stellar atmospheres. In particular, we aim to test whether irregular grids can be used to speed up the 3D NLTE problem, in the same way as depth optimisation can lead to faster running times in 1D. Methods. We created irregular grids based on 3D Voronoi diagrams, sampling different distributions from a 3D radiation-magnetohydrodynamic Bifrost simulation. We developed a method for solving radiation on the 3D irregular grid and implemented a simple NLTE solver using $Λ$-iteration and statistical equilibrium. We applied this to a simplified hydrogen-like atom and studied the convergence properties and accuracy of the irregular grid methods. For reference, we compared them to a standard short-characteristics solver on a regular grid. Results. We find that our method for radiation in irregular grids gives similar results to those from regular grids, and that it is possible to obtain nearly the same results with about ten times fewer points in the irregular grid for the continuum intensity in local thermodynamical equilibrium. We find that the irregular grid can give good results for the NLTE problem, but it takes four times longer per iteration than the regular grid, and it converges in about the same number of iterations. This makes it particularly inefficient. Our formulation therefore does not lead to an improvement. We also find that the design of the irregular grid is crucial for accurate results, and find it non-trivial to design an irregular grid that can work well across a wide range of heights.

description: We determine the frequency of the Yb I $^1S_0 - ^1P_1$ transition at 399 nm using an optical frequency comb. Although this transition was measured previously using an optical transfer cavity [D. Das et al., Phys. Rev. A 72, 032506 (2005)], recent work has uncovered significant errors in that method. We compare our result of 751 526 533.49 $\pm$ 0.33 MHz for the Yb-174 isotope with those from the literature and discuss observed differences. We verify the correctness of our method by measuring the frequencies of well-known transitions in Rb and Cs, and by demonstrating proper control of systematic errors in both laser metrology and atomic spectroscopy. We also demonstrate the effect of quantum interference due to hyperfine structure in a divalent atomic system and present isotope shift measurements for all stable isotopes.

description: The purpose of this thesis was to examine a case study on the didactics of community interpreting. Due to the great arrival of migrants and refugees in Greece, but also internationally, we wanted to know what trainers choose to impart to community interpreters, what are the challenges, and whether their work, the skills they must have, their working conditions, etc. differ compared to conference interpreters. We described the theoretical framework of the sociology of interpretation and then the profile of interpreters as acting subjects in their workplace. We conducted two interviews and analysed them based on the research questions formulated. Finally, we mentioned everything we discovered, citing pieces from the international and domestic literature on the issues raised.

description: Although VCT service is increasingly available in Ethiopia, there is still great reluctance for youth to be tested. There are several possible contributing factors that must be addressed if VCT is to have an important role in HIV prevention and care. The study was conducted from August 2003 to May 2004 to identify factors influencing use of VCT service among 15-24 years old age group in Jijiga town using quantitative and qualitative methods of data collection. The study design is unmatched case-control, where the cases are HIV tested and controls are untested youth. A total of 242 tested and 484 untested youth were included in the study. Of all the socio-demographic and sexual history variables, being female, older youth, educational level of secondary and above grade and sexually active youth were more likely to be tested [AOR (95% CI)=1.52(1.03,2.23)], [AOR (95% CI)=1.93 (1.30,2.87)],[AOR (95% CI)=2.29 (1.03,5.11)], [AOR (95% CI)=2.23(1.42,3.52)], respectively. The main reason for VCT utilization was to know self (61.6%) and have not had HIV test yet because they afraid to get the result. Based on the finding, advocating HIV VCT with proper IEC activities through mass media and peer education for youth in general and male, illiterate, young and not sexually active youth in particular need to be addressed by involving all stakeholders and using local resources, improving training, testing equipment, condom promotion, STI treatment, supervision, referral system, feedback and network are recommended.

description: When the weak value of a projector is 1, a quantum system behaves as in that eigenstate with probability 1. By definition, however, the weak value may take an anomalous value lying outside the range of probability like -1. From the viewpoint of a physical effect, we show that such a negative weak value of -1 can be regarded as the counterpart of the ordinary value of 1. Using photons, we experimentally verify it as the symmetrical shift in polarization depending on the weak value given by pre-postselection of the path state. Unlike observation of a weak value as an ensemble average via weak measurements, the effect of a weak value is definitely confirmed in two photon interference: the symmetrical shift corresponding to the weak value can be directly observed as the rotation angle of a half wave plate.

description: Background: As the US population ages and non-Hodgkin lymphoma (NHL)–specific mortality declines, deaths from causes other than NHL will become increasingly important in treatment decision making for older patients with NHL. The objective of the current study was to describe how the 5-year cumulative incidence of NHL-specific and other-cause mortality varies by subtype, age, comorbidity level, and time since diagnosis in older patients. Methods: Using the Surveillance, Epidemiology, and End Results cancer registry data linked to Medicare claims, patients aged ≥66 years were identified at the time of diagnosis with a first, primary NHL diagnosis from 2004 through 2013. Death certificate data and Fine-Gray competing risks models were used to estimate the 5-year cumulative incidence of NHL-specific and other-cause mortality by NHL subtype, age, and comorbidity level. Estimates were displayed over time using stacked cumulative incidence curves. Results: Among 30,666 patients with NHL, 32% died of NHL and 13% died of other causes within 5 years of diagnosis. The cumulative incidence of other-cause mortality increased with age and comorbidity level for all subtypes. Among patients with aggressive NHL subtypes, NHL-specific mortality exceeded other-cause mortality across all age groups, comorbidity levels, and number of years after diagnosis. For patients with indolent NHL subtypes, other-cause mortality was similar to or exceeded NHL-specific mortality, especially among older patients with severe comorbidity or with the indolent marginal zone, lymphoplasmacytic, and mycosis fungoides subtypes. Conclusions: The findings of the current study suggest that mortality from causes other than NHL are important for patients of an older age, with a higher comorbidity level, and with indolent disease. Evidence from the current study can guide the development of tools for estimating individual prognosis that inform treatment discussions in patients with NHL.

description: Background: International attention to men's participation emerged from the 1994 international conference on population and development (ICPD) in Cairo. Representatives from countries signed an ICPD program of Action (UNFPA, 1995) that emphasized male responsibilities and participation as central components in improving SRH, promoting Gender equality, and empowering women. Objective: Objective of the study was to assess husband involvement during pregnancy and child birth. Methods:- A cross-sectional quantitative study was conducted in Akaki Kality Sub- City among married women who gave live birth in the past one year and attended their children vaccination, FP & counseling in the MCH department of the health facilities. A sample of 422 married women who had given live birth (s) in the past one year were interviewed using interviewer administered questionnaire. Bivariate analysis was done using cross tabulation and then multivariate logistic regression was used to analyze factors that were independently associated with husband involvement during pregnancy and child birth. Results: This study determined the prevalence of husband involvement during ANC (65.5%), labor (80.8%).Factors associated with husband involvement at ANC were Husbands occupation of formal employment (AOR=2.096, 95% CI=1.139, 3.897, P=0.001), Living together of husbands and wives (AOR=12.824, 95% CI=1.211, 135.769, P=0.016).Number received ANC (AOR=2.304, 95% CI=1.290, 4.113, P=0.005). Any signs of pregnancy complications (AOR=3.170, 95% CI=1.787, 5.620 P=0.000). Factors significantly associated with husband involvement during labor were family size of less than five (AOR=2.768 , 95% CI=1.080 , 7.094 , P=0.012),living together of husbands and wives (AOR=14.371, 95% CI=1.205, 171.384, P=0.000),history of abortion (AOR=0.290, 95% CI=0.092, 0.910, P=0.003),and husbands attended ANC (AOR=3.778 , 95% CI= 1.421, 10.044 ,P=0.000). Conclusion and recommendations: Husbands involvement were relatively higher During childbirth, moderate in Birth preparedness and complications readiness, and Relatively lower during ANC. Communities need to be empowered economically and Socially. Men should be considered during IEC of maternal health services.

As a result, we confirmed that, at the focal region where the planetary point spread function exists, the coronagraph system mitigates the raw contrast of a star-planet system by at least $1\times10^{-5}$ even for the 1-$λ/D$ star-planet separation. In addition, the verified coronagraph keeps the shapes of the off-axis point spread functions when the setup has the source angular separation of 1$λ/D$. The low-order wavefront error and the non-zero extinction ratio of the linear polarizer may affect the currently confirmed contrast. The sharpness of the off-axis point spread function generated by the sub-$λ/D$ separated sources is promising for the fiber-based observation of exoplanets. The coupling efficiency with a single mode fiber exceeds 50% when the angular separation is greater than 3--4$\times 10^{-1}λ/D$. For sub-$λ/D$ separated sources, the peak positions (obtained with Gaussian fitting) of the output point spread functions are different from the angular positions of sources; the peak position moved from about $0.8λ/D$ to $1.0λ/D$ as the angular separation of the light source varies from $0.1λ/D$ to $1.0λ/D$. The off-axis throughput including the fiber-coupling efficiency (with respect to no focal plane mask) is about 40% for 1-$λ/D$ separated sources and 10% for 0.5-$λ/D$ separated ones (excluding the factor of the ratio of pupil aperture width and Lyot stop width), where we assumed a linear-polarized-light injection. In addition, because this coronagraph can remove point sources on a line in the sky, it has another promising application for high-contrast imaging of exoplanets in binary systems.

description: Weyl's conformal gravity theory, which is considered as a compelling alternative to general relativity theory, has been claimed to describe the observed flat rotation curve feature of spiral galaxies without the need of invoking dark matter. However, it is important to examine whether the Weyl theory can also explain the relevant gravitational lensing observations correctly without considering any dark matter. In this regard, the gravitational bending angle in static spherically space-time (Mannheim-Kazanas metric) in Weyl theory has been calculated by several authors over the last two decades, but the results are found largely divergent. In this work, we have revisited the problem and obtain the correct and consistent expression of the deflection angle in conformal gravity. Subsequently we perform the gravitational lensing analysis. We compare the prediction of Weyl gravity with the gravitational lensing observations of the rich galaxy clusters Abell 370 and Abell 2390 and is found that Weyl theory cannot describe the stated lensing observations without considering dark matter.

The Einstein-Vlasov system in spherical symmetry: reduction of the equations of motion and classification of single-shell static solutions, in the limit of massless particles

description: We express the Einstein-Vlasov system in spherical symmetry in terms of a dimensionless momentum variable $z$ (radial over angular momentum). This regularises the limit of massless particles, and in that limit allows us to obtain a reduced system in independent variables $(t,r,z)$ only. Similarly, in this limit the Vlasov density function $f$ for static solutions depends on a single variable $Q$ (energy over angular momentum). This reduction allows us to show that any given static metric which has vanishing Ricci scalar, is vacuum at the centre and for $r>3M$ and obeys certain energy conditions uniquely determines a consistent $f=\bar k(Q)$ (in closed form). Vice versa, any $\bar k(Q)$ within a certain class uniquely determines a static metric (as the solution of a system of two first-order quasilinear ODEs). Hence the space of static spherically symmetric solutions of Einstein-Vlasov is locally a space of functions of one variable. For a simple 2-parameter family of functions $\bar k(Q)$, we construct the corresponding static spherically symmetric solutions, finding that their compactness is in the interval $0.7\lesssim \rm max_r(2M/r)\le 8/9$. This class of static solutions includes one that agrees with the approximately universal type-I critical solution recently found by Akbarian and Choptuik (AC) in numerical time evolutions. We speculate on what singles it out as the critical solution found by fine-tuning generic data to the collapse threshold, given that AC also found that {\em all} static solutions are one-parameter unstable and sit on the threshold of collapse.

description: On December 8, 2016, the New England Journal of Medicine published a sounding board on Real World Evidence (RWE)1 by the US Food and Drug Administration (FDA) leadership. While the value of RWE based on nonrandomized observational studies was appreciated, such as for hypothesis generating, safety, and measuring quality in healthcare delivery, the authors expressed concerns on the quality of data sources and the ability of methodologies to control for confounding. In response, we offer a few considerations regarding these concerns.

description: In this work, we study the accuracy that can be achieved when inferring the atmospheric information from realistic numerical magneto-hydrodynamic simulations that reproduce the spatial resolution we will obtain with future observations made by the 4m class telescopes DKIST and EST. We first study multiple inversion configurations using the SIR code and the Fe I transitions at 630 nm until we obtain minor differences between the input and the inferred atmosphere in a wide range of heights. Also, we examine how the inversion accuracy depends on the noise level of the Stokes profiles. The results indicate that when the majority of the inverted pixels come from strongly magnetised areas, there are almost no restrictions in terms of the noise, obtaining good results for noise amplitudes up to 1$\times10^{-3}$ of $I_c$. At the same time, the situation is different for observations where the dominant magnetic structures are weak, and noise restraints are more demanding. Moreover, we find that the accuracy of the fits is almost the same as that obtained without noise when the noise levels are on the order of 1$\times10^{-4}$of $I_c$. We, therefore, advise aiming for noise values on the order of or lower than 5$\times10^{-4}$ of $I_c$ if observers seek reliable interpretations of the results for the magnetic field vector reliably. We expect those noise levels to be achievable by next-generation 4m class telescopes thanks to an optimised polarisation calibration and the large collecting area of the primary mirror.

description: The forecasting of solar energetic particles (SEPs) is a prominent area of space weather research. Numerous forecasting models exist that predict SEP event properties at proton energies <100MeV. One of these models is the SPARX system, a physics-based forecasting tool that calculates >10MeV and >60MeV flux profiles within minutes of a flare being detected. This work describes SPARX-H, the extension of SPARX to forecast SEP events above 300MeV . SPARX-H predicts fluxes in three high energy channels up to several hundred MeV. Correlations between SEP peak flux and peak intensity of the associated solar flare are seen to be weak at high energies, but improved when events are grouped based on the field polarity during the event. Initial results from this new high energy forecasting tool are presented here and the applications of high energy forecasts are discussed. Additionally, the new high energy version of SPARX is tested on a set of historic SEP events. We see that SPARX-H performs best when predicting peak fluxes from events with source locations in well-connected regions, where many large SEP events tend to originate.

description: This is the second in a series of papers associated with cataclysmic variables (CVs) and related objects, formed in a suite of simulations for globular cluster evolution performed with the MOCCA Monte Carlo code. We study the properties of our simulated CV populations throughout the entire cluster evolution. We find that dynamics extends the range of binary CV progenitor properties, causing CV formation from binary progenitors that would otherwise not become CVs. The CV formation rate in our simulations can be separated into two regimes: an initial burst ($\lesssim$ 1 Gyr) connected with the formation of the most massive white dwarfs, followed by a nearly constant formation rate. This result holds for all models regardless of the adopted initial conditions, even when most CVs form dynamically. Given the cluster age-dependence of CV properties, we argue that direct comparisons to observed Galactic field CVs could be misleading, since cluster CVs can be up to 4 times older than their field counterparts. Our results also illustrate that, due mainly to unstable mass transfer, some CVs that form in our simulations are destroyed before the present-day. Finally, some field CVs might have originated from globular clusters, as found in our simulations, although the fraction of such escapers should be small relative to the entire Galactic field CV population.
