description: Measurements of double helicity asymmetries in inclusive hadron production in polarized $p + p$ collisions are sensitive to helicity-dependent parton distribution functions, in particular to the gluon helicity distribution, ∆g. This study focuses on the extraction of the double helicity asymmetry in $\eta$ production ($\vec{p}+\vec{p}$ → $\eta+X$), the $\eta$ cross section and the $\eta/\pi^0$ cross section ratio. The cross section and ratio measurements provide essential input for the extraction of fragmentation functions that are needed to access the helicity-dependent parton distribution functions.

CP violation in the interference between $ρ(770)^0$ and $S$-wave in $B^\pm\to π^+ π^-π^\pm$ decays and its implication for CP asymmetry in $B^\pm\to ρ^0π^\pm$

description: The decay amplitude analyses of $B^\pm\to π^+ π^-π^\pm$ decays in the Dalitz plot performed by LHCb indicate that CP asymmetry for the dominant quasi-two-body decay $B^\pm\toρ(770)^0π^\pm$ was found to be consistent with zero in all three approaches for the $S$-wave component and that CP-violation effects related to the interference between the $ρ(770)^0$ resonance and the $S$-wave were clearly observed. We show that the nearly vanishing CP violation in $B^\pm\toρ^0π^\pm$ is understandable within the framework of QCD factorization. There are two $1/m_b$ power corrections, one from penguin annihilation and the other from hard spectator interactions. They contribute destructively to $A_{CP}(B^\pm\toρ^0π^\pm)$ to render it compatible with zero, in contrast to the sizable negative CP asymmetry predicted in most of the existing models. We next show that the measured interference pattern between the $ρ$ and $S$-wave contributions in the low $m_{π^+π^-}$ region separated by the sign of value of $\cosθ$ with $θ$ being the angle between the two same charged pions measured in the rest frame of the $ρ$ resonance can be explained in terms of the smallness of $A_{CP}(B^+\toρ^0π^+)$ and the interference between $ρ(770)$ and $σ/f_0(500)$. If CP asymmetry in $B^\pm\toρ^0π^\pm$ is not negligible as predicted in many existing models, the observed interference pattern will be destroyed. We conclude that the experimental observation of the interference pattern between $P$- and $S$-waves in the low-$m_{π^+π^-}$ region between 0.5 and 1.0 GeV is consistent with a nearly vanishing CP violation in $B^\pm\toρ^0π^\pm$.

Assessment of occupational injury and associated factors among Mugher cement factory workers, Mugher, Ethiopia
Creators: name: Gebretsadik, Mulu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: Back ground-Throughout the world, occupational exposure to cement dust and noise continue to cause serious public health problems and are leading cause of disability and disease among workers. There are 2 million work-related deaths annually worldwide. Studies done in Ethiopia on textile factory, Iron and steel factory and among small and medium scale industries, occupational injury is the cause for hospitalization, disability and death of workers. There is no study done on the prevalence and associated factors of occupational injury in cement factory. Objectives-this study investigated the prevalence and determinants of occupational injuries among cement factory workers in Mugher. Methods -An institution based cross sectional study complemented with work place observation checklist and record review was conducted. Stratified random sampling by job category was used to get the desired sampling unit. The study participants were selected using simple random sampling technique, lottery method. Data was collected by trained data collectors using pretested Amharic version questionnaire through face to face interview of the study participants after getting ethical clearance from responsible bodies and informed verbal consent from study participants. The raw data was edited, entered in to a computer using Epi Info version 3.5.0 then exported to IBM SPSS version 21 and cleaned. Data was analyzed using IBM SPSS version 21. Bivariate analysis &multivariate analysis was done.95% confidence interval and p-value <0.05 was used. Results: The prevalence of occupational injury in one year was 10.4%.There was one report with disability .In addition, 1356 working days were lost as a result of 52 work related injuries.Thirty seven (71.2%) were hospitalized, accounting for 51.4% hospitalization for more than 24 hours, 18(34.6%) were absent from work for 15-30 days .The significant contributing factor for occupational injuries was job category. Workers in the cement production were 74.7% less likely to experience occupational injury than workers in clinker production [AOR= 0.25, CI :( 0.100-0.639)], workers in the raw material production had 73.6 % less likely to experience occupational injury than workers in the clinker production [AOR= 0.26, CI :( 0.107-0.653)]. Conclusion and recommendation: The prevalence of occupational injury was 10.4%. Job category increased the risk of work related injuries. Preventive measures like provision of adequate and quality safety materials timely and work place supervision should get focus.

We show that the local spin Hamiltonian obtained from the six-vertex model with alternating inhomogeneities in fact leads to the Sine-Gordon model in the low-energy limit. We show that the Bethe Ansatz results for this model lead to the correct general relations for different critical exponents of the coupling constant.

description: The origin of star-formation in customarily passively evolving early-type massive galaxies is poorly understood. We present a case study of a massive galaxy, I~Zw~81, inside the Bootes void. The void galaxy is known to host an active galactic nuclei (AGN). Our detailed 2D decomposition of the surface brightness distribution in the $Canada$ $France$ $Hawaii$ $Telescope$ ($CFHT$) g- and r-bands revealed multiple structural components such as a nuclear point source, a bar, a ring, and an inner exponential disk followed by an outer low surface brightness (LSB) disk. I~Zw~81 turns out to be a disk-dominated galaxy with lenticular morphology. The modelling of the multi-wavelength spectral energy distribution (SED) shows that the galaxy is star-forming (SF), and belongs to the blue cloud. We find that the optical (g$-$r) color of the bar is bluer than the disks, and the far- and near-ultraviolet emission inside the galaxy observed with Ultraviolet Imaging Telescope (UVIT) onboard {\em AstroSat} is concentrated in the central few kpc region enclosing the bar. The strong bar might be playing a pivotal role in driving the gas inflow and causing SF activity in tandem with the minor merger-like interactions as evident from the deep $CFHT$ data. The low-luminosity AGN is insufficient to quench the central SF. The results are peculiar from the standpoint of a massive barred lenticular galaxy.

description: In this paper, the results of computer simulations based on Nowak--Szamrej--Latané model with multiple (from two to five) opinions available in the system are presented. We introduce the noise discrimination level (which says how small the clusters of agents could be considered as negligible) as a quite useful quantity that allows qualitative characterization of the system. We show that depending on the introduced noise discrimination level, the range of actors' interactions (controlled indirectly by an exponent in distance scaling function, the larger the exponent the more influential the nearest neighbors are) and the information noise level (modeled as social temperature, which increases results in increase of randomness in taking the opinion by the agents), the ultimate number of the opinions (measured as the number of clusters of actors sharing the same opinion in clusters greater than the noise discrimination level) may be smaller than the number of opinions available in the system. These are observed in small and large information noise limits but result in either unanimity, or polarization, or randomization of opinions.

description: The role of sounds produced by free-flying insects is challenging to research due to technical difficulties in obtaining audio recordings suitable for playback experiments. Experimental studies using flight sounds are needed to understand if buzzes carry information and by whom it is perceived. We developed the 'buzzOmeter system' for recording untethered, flying insects in their habitat, followed by file processing that allows precise measurements of acoustic parameters, including those dependent on the distance of the sound source from the microphone, i.e. signal magnitude measurements. The system consists of commercially available elements and open-source software. We provide a practical guide for the assembly and use of two alternative setups of the buzzOmeter system, followed by a video tutorial on file processing and an R script for the assignment of audio recordings to the corresponding species based on mixture discriminant analysis. Recordings of nine insect species (bees, wasps and lepidopterans) obtained with the use of our system in various habitats demonstrate its feasibility for field studies. Diverse species interactions are based on sound, and our new tool can aid researchers studying acoustical signalling in predator-prey, pollinator-plant and mimic-model complexes, among others.

description: We attempt to grasp the mathematics behind the planetary theories of the Syrian astronomer Ibn al-Shatir (1304-1375) in his treatise Nihayat al-Sul. Following the Maragha school of astronomers, by composing circular movements with constant angular velocity, Ibn al-Shatir attains two goals. He eliminates the need of excentrics and equant points in astronomy; but he also describes longitudes and latitudes with a unique method, with no more orbs than what is strictly necessary to the longitudes. A better understanding of rotation as a spatial transformation enables this ultimate economy of thought. In our commentary, we take Venus as an example offering an interesting problem about the latitudes. It is the opportunity to give the edition of the chapter of the Nihayat al-Sul dedicated to the latitudes of Mercury and Venus.

description: Deep generative models including generative adversarial networks (GANs) are powerful unsupervised tools in learning the distributions of data sets. Building a simple GAN architecture in PyTorch and training on the CANDELS data set, we generate galaxy images with the Hubble Space Telescope resolution starting from a noise vector. We proceed by modifying the GAN architecture to improve the Subaru Hyper Suprime-Cam ground-based images by increasing their resolution to the HST resolution. We use the super resolution GAN on a large sample of blended galaxies which we create using CANDELS cutouts. In our simulated blend sample, $\sim 20 \%$ would unrecognizably be blended even in the HST resolution cutouts. In the HSC-like cutouts this fraction rises to $\sim 90\%$. With our modified GAN we can lower this value to $\sim 50\%$. We quantify the blending fraction in the high, low and GAN resolutions over the whole manifold of angular separation, flux ratios, sizes and redshift difference between the two blended objects. The two peaks found by the GAN deblender result in ten times improvement in the photometry measurement of the blended objects. Modifying the architecture of the GAN, we also train a Multi-wavelength GAN with seven band optical+NIR HST cutouts. This multi-wavelength GAN improves the fraction of detected blends by another $\sim 10\%$ compared to the single-band GAN. This is most beneficial to the current and future precision cosmology experiments (e.g., LSST, SPHEREx, Euclid, Roman), specifically those relying on weak gravitational lensing, where blending is a major source of systematic error.

description: The prevalence and determinants of substance use (a lcohol, khat, cigarette), mental illness, s u icidal a t tempt, STDs and teenage pregnancy among adolescents aged 10-24 years have not been well documented in the country. A community based cross - sectional study was conducted in Awassa Zuria Woreda, southern Ethiopia from November to December 1994 G.C. A total of 1953 adolescents were included in the study . Data were collected using questionnaire by trained interviewers. The likelihood of substance (alcohol, Khat, Cigarette) use on average was at least two times higher (p<0.05) among adolescents who reported history of run away from their family and police arrest. Mental illness, suicidal attempt, STDs and teenage pregnancy were found to be more likely to occur among adolescents who use one or more of the substances than others. The older adolescents in general were found to be more likely to be exposed to all of the heal th related problems studied. Risk factors identified for substance use and association of substance use with the health related problems among adolescents were observed in this study. The level s and the interactions observed between the adolescent risk behaviours and hea lth related problems indicate the need to set an immediate intervention programmes .

description: 3D silicon pixel detectors have been investigated as radiation-hard candidates for the innermost layers of the HL-LHC upgrade of the ATLAS pixel detector. 3D detectors are already in use today in the ATLAS IBL and AFP experiments. These are based on 50x250 um2 large pixels connected to the FE-I4 readout chip. Detectors of this generation were irradiated to HL-LHC fluences and demonstrated excellent radiation hardness with operational voltages as low as 180 V and power dissipation of 12--15 mW/cm2 at a fluence of about 1e16 neq/cm2, measured at -25 degree C. Moreover, to cope with the higher occupancies expected at the HL-LHC, a first run of a new generation of 3D detectors designed for the HL-LHC was produced at CNM with small pixel sizes of 50x50 and 25x100 um2, matched to the FE-I4 chip. They demonstrated a good performance in the laboratory and in beam tests with hit efficiencies of about 97% at already 1--2V before irradiation.

description: Models of planetary core growth by either planetesimal or pebble accretion are traditionally disconnected from the models of dust evolution and formation of the first gravitationally-bound planetesimals. The state-of-the-art models typically start with massive planetary cores already present. We aim to study the formation and growth of planetary cores in a pressure bump, motivated by the annular structures observed in protoplanetary disks, starting with sub-micron-sized dust grains. We connect the models of dust coagulation and drift, planetesimal formation in the streaming instability, gravitational interactions between planetesimals, pebble accretion, and planet migration, into one uniform framework. We find that planetesimals forming early at the massive end of the size distribution grow quickly dominantly by pebble accretion. These few massive bodies grow on the timescales of ~100 000 years and stir the planetesimals formed later preventing the emergence of further planetary cores. Additionally, a migration trap occurs allowing for retention of the growing cores. Pressure bumps are favourable locations for the emergence and rapid growth of planetary cores by pebble accretion as the dust density and grain size are increased and the pebble accretion onset mass is reduced compared to a smooth-disk model.

description: Back ground : Every year about 12 million children die before reaching their fifth birthday .Over 70% of these deaths occur in the developing world, Ethiopia is one of these countries with unacceptably high infant and under five child mortality rate of 96.8 and 141/ 1000 respectively. Acute respiratory infections, diarrhoeal diseases, malaria, measles and malnutrition are the major causes. Objective : To investigate factors influencing the compliance of carers of under five children receiving IMCI, in Awassa H. centre, Awassa town, SNNPR state, Ethiopia. Method : A cross sectional survey was conducted from October to June 2006. The study population were all carers of under five children who attended IMCI clinic at Awassa Health centre. The sample size required for this study was determined using the formula for estimating single population proportion and a total of 401 carers were used. Data entry and analysis were conducting using Epi Info 2002 and SPSS. Result : Health workers explained correctly how to give antibiotic to 274(89.5%) of carers but demonstrated to only 19(6.2%) of carers. 65(21.3%) of carers gave antibiotic correctly. ORS was given correctly by 30(19.8%) of carers and 25(19.1%) of carers were attend follow up. 175(72.9%) of carers said they did not know how to give antibiotic. Concerning safe relief of cough 46(24.5%) of carers used safe remedy. 266(66.3%) of carers provided less fluid or fluid as usually to sick children after visiting the health center.

description: Discoveries of planet- and stellar remnant-hosting pulsars challenge our understanding as the violent supernova explosion that forms the pulsar presumably destabilizes the system. Type II supernova explosions lead to the formation of eccentric bound systems, free-floating planets, neutron stars, pulsars, and white dwarfs. Analytical and numerical studies of high mass-loss rate systems based on perturbation theory so far have focused mainly on planet-star systems. In this paper, we extend our understanding of the fate of planet-star and binary systems by assuming a homologous envelope expansion model using a plausible ejection velocity ($1000-10000\,\mathrm{km/s}$), envelope- and neutron star masses. The investigation covers secondary masses of 1-10MJup for planetary, and 1-20MSun for stellar companions. We conduct and analyze over 2.5 million simulations assuming different semi-major axes (2.23 - 100au), eccentricities (0-0.8), and true-anomalies (0-2pi) for the companion. In a homologous expansion scenario, we confirm that the most probable outcome of the explosion is the destabilization of the system, while the retention of a bound system requires a highly eccentric primordial orbit. In general, a higher ejecta velocity results in a lower eccentricity orbit independent of secondary mass. The explanation of close-in pulsar planets requires exotic formation scenarios, rather than survival through the type II supernova explosion model. Post-explosion bound star systems gain a peculiar velocity (<100\,km/s), even though the explosion model is symmetric. The applied numerical model allows us to derive velocity components for dissociating systems. The peculiar velocities of free-floating planets and stellar corpses are in the range of 10^-6-275km/s.

description: A novel atomistic effective Hamiltonian scheme, incorporating an original and simple bilinear energetic coupling, is developed and used to investigate the temperature dependent physical properties of the prototype antiferroelectric PbZrO3 (PZO) system. This scheme reproduces very well the known experimental hallmarks of the complex Pbam orthorhombic phase at low temperatures and the cubic paraelectric state of Pm 3m symmetry at high temperatures. Unexpectedly, it further predicts a novel intermediate state also of Pbam symmetry, but in which anti-phase oxygen octahedral tiltings have vanished with respect to the Pbam ground state. Interestingly, such new state exhibits a large dielectric response and thermal expansion that remarkably agree with previous experimental observations and the x-ray experiments we performed. We also conducted direct first-principles calculations at 0K which further support such low energy phase. Within this fresh framework, a re-examination of the properties of PZO is thus called for.

description: In this paper we give an explicit construction of unfolded equations for massive higher spin supermultiplets of the minimal (1,0) supersymmetry in AdS_3 space. For that purpose we use an unfolded formulation for massive bosonic and fermionic higher spins and find supertransformations leaving appropriate set of unfolded equations invariant. We provide two general supermultiplets (s, s+1/2) and (s, s-1/2) with arbitrary integer s, as well as a number of lower spin examples.

description: Majorana fermion dynamics may arise at the edge of Kitaev wires or superconductors. Alternatively, it can be engineered by using trapped ions or ultracold atoms in an optical lattice as quantum simulators. This motivates the theoretical study of Majorana fermions confined to a finite volume, whose boundary conditions are characterized by self-adjoint extension parameters. While the boundary conditions for Dirac fermions in $(1+1)$-d are characterized by a 1-parameter family, $λ= - λ^*$, of self-adjoint extensions, for Majorana fermions $λ$ is restricted to $\pm i$. Based on this result, we compute the frequency spectrum of Majorana fermions confined to a 1-d interval. The boundary conditions for Dirac fermions confined to a 3-d region of space are characterized by a 4-parameter family of self-adjoint extensions, which is reduced to two distinct 1-parameter families for Majorana fermions. We also consider the problems related to the quantum mechanical interpretation of the Majorana equation as a single-particle equation. Furthermore, the equation is related to a relativistic Schrödinger equation that does not suffer from these problems.

description: Giant planets around young stars serve as a clue to unveiling their formation history and orbital evolution. CI Tau is a 2\,Myr-old classical T-Tauri star hosting an eccentric hot Jupiter, CI Tau\,b. The standard formation scenario of a hot Jupiter predicts that planets formed further out and migrated inward. A high eccentricity of CI Tau b may be suggestive of high-$e$ migration due to secular gravitational perturbations by an outer companion. Also, ALMA 1.3\,mm-continuum observations show that CI Tau has at least three annular gaps in which unseen planets may exist. We present high-contrast imaging around CI Tau taken from Keck/NIRC2 $L^{\prime}$-band filter and vortex coronagraph that allows us to search for an outer companion. We did not detect any outer companion around CI Tau from angular differential imaging (ADI) using two deep imaging data sets. The detection limits from ADI-reduced images rule out the existence of an outer companion beyond $\sim30$\,au that can cause the Kozai-Lidov migration of CI Tau\,b. Our results suggest that CI Tau\,b may have experienced Type II migration from $\lesssim 2$\,au in Myrs. We also confirm that no planets with $\geq 2-4\,M_\mathrm{Jup}$ are hidden in two outer gaps.

description: We study the synchronization of chaotic units connected through time-delayed fluctuating interactions. We focus on small-world networks of Bernoulli and Logistic units with a fixed chiral backbone. Comparing the synchronization properties of static and fluctuating networks, we find that random network alternations can enhance the synchronizability. Synchronized states appear to be maximally stable when fluctuations are much faster than the time-delay, even when the instantaneous state of the network does not allow synchronization. This enhancing effect disappears for very slow fluctuations. For fluctuation time scales of the order of the time-delay, a desynchronizing resonance is reported. Moreover, we observe characteristic oscillations, with a periodicity related to the coupling delay, as the system approaches or drifts away from the synchronized state.

description: Introduction: Institutional delivery, a childbirth conducted by skill attendant in health facility built, equipped and managed to provide safe delivery service as one of its function, is responsible to provide greater assurance to find skilled attendant, essential equipment and drugs to manage labour and referral transportation as the need arises. Objective: This study assessed factors that affect utilization of institutional delivery among child bearing age women in Harari Region. Methodology: Community based unmatched case control study complemented with qualitative design was employed to assess factors that affect utilization of institutional delivery. Totally, 462 mothers 154 cases and 308 controls who had delivery within the last 24 months were enrolled and interviewed with pre tested questionnaire using Face-to-face interview & in-depth interview of key informants as data collection methods. EPI INFO Version 3.5.1 and SPSS version 15 statistical software were used to enter and analyze the data, respectively. Descriptive statistics, Univariate, Bivariate and Multivariate analysis of logistic regression as well as X2 test were used to determine factors that affect institutional delivery utilization. P-Value less than 5%, OR with 95% CI were used to show statistically significant association. Results: This study singled out a number of factors that affect institutional delivery utilization, mothers with secondary and more educations were 5.8 times more likely to use facility delivery compared with those had no formal education. Similarly mothers from house holds with 500ETB and more monthly income were 2.4 times more likely to use facility delivery. Obstetric factors such as ANC use, previous delivery complications, previous facility delivery utilization, Knowledge of risk associated with home delivery and benefit of institutional delivery were found to be independent predictors of institutional delivery utilization. Conclusion and Recommendations: factors that affect facility delivery utilization found to be different and interrelated at individual, family and community level. Based on these facts Promotion of women/girl education, promotion of income generating activities, health information, communication based on obstetric risk and benefit of safe delivery, organizing and promoting mother and community support group to improve awareness on planned and safe delivery are recommended.
