description: Any recipe to grow black hole hair has to circumvent no-hair theorems by violating some of their assumptions. Recently discovered hairy black hole solutions exist due to the fact that their scalar fields don't inherit the symmetries of the spacetime metric. We present here a general analysis of the constraints which limit the possible forms of such a hair, for both the real and the complex scalar fields. These results can be taken as a novel piece of the black hole uniqueness theorems or simply as a symmetry noninheriting Ansätze guide. In addition we introduce new classification of the gravitational field equations which might prove useful for various generalizations of the theorems about spacetimes with symmetries.

The Contribution of Group-Based Micro and Small Enterprises to the Local Economy and Social Development in the Arada Sub City: A Case Study on Metal and Wood Work Enterprises
Creators: name: Belay, Endalsasa
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2012

description: The main objective of this study is to investigate the Contribution of Group-Based Micro and Small Enterprisers (specifically metal and wood work enterprises) to the local economy and social development in the Arada Sub city. Both primary and secondary data were employed. Questionnaire, key informant interview and observation were the main data collection instruments. Among the 10 woredas in the sub city, 4 of them (woreda 2, 3, 6 & 9) were purposely selected due to their relative performance. Among the 4 woredas, 16 group-based enterprises and a sample size of 97 respondents were covered. The quantitative data was analyzed using simple statistical techniques like tables, charts and graphs. Narration method was employed to analyze the qualitative data. The findings of the study indicated that MSEs have great influential nature in the locality in terms of economic (be good source of income for local individuals) as well as non economic (for the development social capital/resource) contributions. Furthermore, the research finding showed that lack of capital, limited working space, lack of market, lack of raw material inputs, unfair treatment among enterprises by the government, absence of display centers, difficult collateral to get loan from financial institutions are some of the constraints that hinder operation of MSEs. All in all, there is a need for strengthening the growth of MSEs and thereby enhancing their socio-economic contributions by widening access to loans, providing working premises in the appropriate place, and strengthening both financial and non-financial (Business Development Services) supports

description: We describe the competitive motion of (N + 1) incompressible immiscible phases within a porous medium as the gradient flow of a singular energy in the space of non-negative measures with prescribed mass endowed with some tensorial Wasserstein distance. We show the convergence of the approximation obtained by a minimization schemè a la [R. Jordan, D. Kinder-lehrer \& F. Otto, SIAM J. Math. Anal, 29(1):1--17, 1998]. This allow to obtain a new existence result for a physically well-established system of PDEs consisting in the Darcy-Muskat law for each phase, N capillary pressure relations, and a constraint on the volume occupied by the fluid. Our study does not require the introduction of any global or complementary pressure.

description: We address the problem of controlling a motorized kite of an Airborne Wind Energy System (AWES) during the take-off and landing maneuvers, using a circular path. Airborne Wind Energy (AWE) is the name given to concepts that convert wind energy into electricity, relying on autonomous kites or flying devices linked to the ground by one or more tethers. AWE systems offer several potential advantages over conventional wind turbines. They require less material than tower-based turbines, have the potential to be manufactured at a lower cost, can be quickly deployed and can harness stronger and steadier winds by flying at higher altitudes. One of the main challenges in AWES is the ability to operate safely, reliably, and autonomously for long periods of time in different weather and environmental conditions. For a complete flight cycle of the kite used on these systems and for it to function at its highest performance, it is mandatory to have an automatic take-off and landing of these systems. A solution is yet to be established, and various research teams and universities are still addressing this problem. To address this problem, we propose a circular take-off and landing (CTOL) approach, similar to [1], on which the kite has self-propulsion, and the tether is aligned with the wing during the kite acceleration. We use a modification of the model [2], [3] based on a mass–point model. We model a tethered kite with self-propulsion using Matlab/Simulink and develop a control scheme to confer the take-off and landing ability to an AWE system. The control inputs of the model are the throttle and the angle of attack of the kite. The kite starts in a rest position, having zero velocity. When performing the take-off procedure, the kite starts to accelerate, gaining velocity. Since it is connected to the ground station via a tether, the kite is forced to describe a circular path around the ground station. Using sliding mode control to uncover the relationship between the kite position and attitude and the inputs, namely the angle-of-attack and the throttle, we can increase its altitude, ensuring its safety. The same procedure is used for landing. The controllers resulting from our simulations are applied to a small-scale physical prototype. REFERENCES: [1] A. Cherubini, B. Szalai, R. Schmehl, and M.

description: The issue of career orientations has become a critical component of career development of professionals in a rapidly changing world. To this effect, the career orientations of professionals employees is considered to have important implications for their job satisfaction, commitment, and retention within organizations. However, career orientations of professionals in general and that of Accounting professionals in particular have not yet been studied in Ethiopia. In view of the above, this study examines the career orientation held by accounting professionals in Ethiopia and the variation in the distribution of career orientation among category of accounting professionals having different occupational/ professionals status. Data for the study were obtained from 40 accounting professionals working in various organizations in Addis Ababa. The findings of the study suggest that the most prevalent career orientation among accounting professionals included in the sample are service/ dedication to a cause, entrepreneurial creativity, pure challenge and life style. The remaining types of career orientations (technical functional, general management competence, Autonomy/independence, security /stability.) are found to be less predominant. However the results obtained for each dimensions indicated the existence of variation in the distribution of career orientation across the sample categories of accounting professionals.

Factors That Determine Film Genre Preference Of Audiences: The Case Of Three Selected Government Owned Cinemas In Addis Ababa
Creators: name: Mohammed, Yesuf
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: People use different mechanisms to quench their thirst for entertainment, information and communication. There are myriad of entertainment alternatives and film is among those which attract numerous number of audiences. Movies play a pivotal role in relaying messages in a manner that is based on the interest of a particular target audience. Over the past few years the number of films produced and movie-goers have increased. It is not uncommon to hear people criticizing our local films for being narrow, lack of originality, and for their superficial & similar plots. Even though there is a big appetite for various film genres with different themes, many of the films that are being released seem to revolve around only romance, drama, tragedy and comedy. The purpose of the study was to describe factors that determine film genre preference of audiences. Theoretical and empirical literatures were reviewed to formulate the hypotheses of the study. To accomplish the objectives of the study a survey of 400 audiences found at the three government owned cinemas (Cinema Ampere, Cinema Ethiopia, and Ambassador Cinema) was conducted. Deductive approach, descriptive research design and quantitative research method were employed in order to conduct the study Survey questionnaire was used as a strategic instrument to gather the required primary data from the sample population. The descriptive and inferential analyses of the collected data were conducted with the help of SPSS version 20. The key finding attained from the hypotheses tested using chi square indicated that gender, age, and level of education did have a strong association with film genre preference of the respondents. It was further revealed that action, war, horror, crime, suspense, and adventure were cited as films the audiences would like to watch locally made. Advertising, poster, word-of-mouth, budget, director, and publicity were found to be other factors that influenced film genre preference of the audiences. Eventually, some recommendations to alleviate the problems associated with Ethiopian film industry and suggestions for future research were made.

description: Semantic maps represent the environment using a set of semantically meaningful objects. This representation is storage-efficient, less ambiguous, and more informative, thus facilitating large-scale autonomy and the acquisition of actionable information in highly unstructured, GPS-denied environments. In this letter, we propose an integrated system that can perform large-scale autonomous flights and real-time semantic mapping in challenging under-canopy environments. We detect and model tree trunks and ground planes from LiDAR data, which are associated across scans and used to constrain robot poses as well as tree trunk models. The autonomous navigation module utilizes a multi-level planning and mapping framework and computes dynamically feasible trajectories that lead the UAV to build a semantic map of the user-defined region of interest in a computationally and storage efficient manner. A drift-compensation mechanism is designed to minimize the odometry drift using semantic SLAM outputs in real time, while maintaining planner optimality and controller stability. This leads the UAV to execute its mission accurately and safely at scale.

description: Self-assembly of protein monomers into distinct membrane protein oligomers provides a general mechanism for diversity in the molecular architectures, and resulting biological functions, of membrane proteins. We develop a general physical framework describing the thermodynamic competition between different oligomeric states of membrane proteins. Using the mechanosensitive channel of large conductance as a model system, we show how the dominant oligomeric states of membrane proteins emerge from the interplay of protein concentration in the cell membrane, protein-induced lipid bilayer deformations, and direct monomer-monomer interactions. Our results suggest general physical mechanisms and principles underlying regulation of protein function via control of membrane protein oligomeric state.

Equations of mirrors to log Calabi--Yau pairs via the heart of canonical wall structures

description: Gross and Siebert developed a program for constructing in arbitrary dimension a mirror family to a log Calabi--Yau pair $(X,D)$, consisting of a smooth projective variety $X$ with a normal-crossing anti-canonical divisor $D$ in $X$. In this paper, we provide an algorithm to practically compute explicit equations of the mirror family in the case when $X$ is obtained as a blow-up of a toric variety along hypersurfaces in its toric boundary, and $D$ is the strict transform of the toric boundary. The main ingredient is ``the heart of the canonical wall structure'' associated to such pairs $(X,D)$, which is constructed purely combinatorially, following our previous work with Mark Gross. In the case when we blow up a single hypersurface we show that our results agree with previous results computed symplectically by Aroux--Abouzaid--Katzarkov. In the situation when the locus of blow-up is formed by more than a single hypersurface, due to infinitely many walls interacting, writing the equations becomes significantly more challenging. We provide the first examples of explicit equations for mirror families in such situations.

description: Photons entangled in their position-momentum degrees of freedom (DoFs) serve as an elegant manifestation of the Einstein-Podolsky-Rosen paradox, while also enhancing quantum technologies for communication, imaging, and computation. The multi-mode nature of photons generated in parametric downconversion has inspired a new generation of experiments on high-dimensional entanglement, ranging from complete quantum state teleportation to exotic multi-partite entanglement. However, precise characterisation of the underlying position-momentum state is notoriously difficult due to limitations in detector technology, resulting in a slow and inaccurate reconstruction riddled with noise. Furthermore, theoretical models for the generated two-photon state often forgo the importance of the measurement system, resulting in a discrepancy between theory and experiment. Here we formalise a description of the two-photon wavefunction in the spatial domain, referred to as the collected joint-transverse-momentum-amplitude (JTMA), which incorporates both the generation and measurement system involved. We go on to propose and demonstrate a practical and efficient method to accurately reconstruct the collected JTMA using a simple phase-step scan known as the $2Dπ$-measurement. Finally, we discuss how precise knowledge of the collected JTMA enables us to generate tailored high-dimensional entangled states that maximise discrete-variable entanglement measures such as entanglement-of-formation or entanglement dimensionality, and optimise critical experimental parameters such as photon heralding efficiency. By accurately and efficiently characterising photonic position-momentum entanglement, our results unlock its full potential for discrete-variable quantum information science and lay the groundwork for future quantum technologies based on multi-mode entanglement.

Bayesian Mass Estimates of the Milky Way: including measurement uncertainties with hierarchical Bayes

description: We present a hierarchical Bayesian method for estimating the total mass and mass profile of the Milky Way Galaxy. The new hierarchical Bayesian approach further improves the framework presented by Eadie, Harris, & Widrow (2015) and Eadie & Harris (2016) and builds upon the preliminary reports by Eadie et al (2015a,c). The method uses a distribution function $f(\mathcal{E},L)$ to model the galaxy and kinematic data from satellite objects such as globular clusters (GCs) to trace the Galaxy's gravitational potential. A major advantage of the method is that it not only includes complete and incomplete data simultaneously in the analysis, but also incorporates measurement uncertainties in a coherent and meaningful way. We first test the hierarchical Bayesian framework, which includes measurement uncertainties, using the same data and power-law model assumed in Eadie & Harris (2016), and find the results are similar but more strongly constrained. Next, we take advantage of the new statistical framework and incorporate all possible GC data, finding a cumulative mass profile with Bayesian credible regions. This profile implies a mass within $125$kpc of $4.8\times10^{11}M_{\odot}$ with a 95\% Bayesian credible region of $(4.0-5.8)\times10^{11}M_{\odot}$. Our results also provide estimates of the true specific energies of all the GCs. By comparing these estimated energies to the measured energies of GCs with complete velocity measurements, we observe that (the few) remote tracers with complete measurements may play a large role in determining a total mass estimate of the Galaxy. Thus, our study stresses the need for more remote tracers with complete velocity measurements.

description: Genetic analysis methods are foundational to advancing personalized and preventative medicine, accelerating disease diagnostics, and monitoring the health of organisms and ecosystems. Current nucleic acid technologies such as polymerase chain reaction (PCR), next-generation sequencing (NGS), and DNA microarrays rely on fluorescence and absorbance, necessitating sample amplification or replication and leading to increased processing time and cost. Here, we introduce a label-free genetic screening platform based on high quality (high-Q) factor silicon nanoantennas functionalized with monolayers of nucleic acid fragments. Each nanoantenna exhibits substantial electromagnetic field enhancements with sufficiently localized fields to ensure isolation from neighboring resonators, enabling dense biosensor integration. We quantitatively detect complementary target sequences using DNA hybridization simultaneously for arrays of sensing elements patterned at densities of 160,000 pixels per cm$^2$. In physiological buffer, our nanoantennas exhibit average resonant quality factors of 2,200, allowing detection of two gene fragments, SARS-CoV-2 envelope (E) and open reading frame 1b (ORF1b), down to femtomolar concentrations. We also demonstrate high specificity sensing in clinical nasopharyngeal eluates within 5 minutes of sample introduction. Combined with advances in biomarker isolation from complex samples (e.g., mucus, blood, wastewater), our work provides a foundation for rapid, compact, amplification-free and high throughput multiplexed genetic screening assays spanning medical diagnostics to environmental monitoring.

description: High pressure X-ray diffraction measurements have been carried out on the intermetallic semiconductor FeGa$_3$ and the equation of state for FeGa$_3$ has been determined. First principles based DFT calculations within the GGA approximation indicate that although the unit cell volume matches well with the experimentally obtained value at ambient pressure, it is significantly underestimated at high pressures and the difference between them increases as pressure increases. GGA + U calculations with increasing values of U$_{Fe(3d)}$ (on-site Coulomb repulsion between the Fe 3d electrons) at high pressures, correct this discrepancy. Further, the GGA+U calculations also show that along with U$_{Fe(3d)}$, the Fe 3d band width also increases with pressure and around a pressure of 4 GPa, a small density of states appear at the Fermi level. High pressure resistance measurements carried out on FeGa$_3$ also clearly show a signature of an electronic transition. Beyond the pressure of 19.7 GPa, the diffraction peaks reduce in intensity and are not observable beyond $\sim$ 26 GPa, leading to an amorphous state.

The aim of this paper is to investigate combinatorial properties of path posets, and to provide computational tools for multipath cohomology. In particular, we develop acyclicity criteria, and provide computations of multipath cohomology groups of oriented linear graphs. We further interpret the path poset as the face poset of a simplicial complex, and we investigate realisability problems.

description: We present nebular-phase imaging and spectroscopy for the hydrogen-poor superluminous supernova SN 2015bn, at redshift z=0.1136, spanning +250-400 d after maximum light. The light curve exhibits a steepening in the decline rate from 1.4 mag/(100 d) to 1.7 mag/(100 d), suggestive of a significant decrease in the opacity. This change is accompanied by a transition from a blue continuum superposed with photospheric absorption lines to a nebular spectrum dominated by emission lines of oxygen, calcium and magnesium. There are no obvious signatures of circumstellar interaction or large nickel mass. We show that the spectrum at +400 d is virtually identical to a number of energetic Type Ic supernovae such as SN 1997dq, SN 2012au, and SN 1998bw, indicating similar core conditions and strengthening the link between `hypernovae'/long gamma-ray bursts and superluminous supernovae. A single explosion mechanism may unify these events that span absolute magnitudes of -22 < M_B < -17. Both the light curve and spectrum of SN 2015bn are consistent with an engine-driven explosion ejecting 7-30 M$_\odot$ of oxygen-dominated ejecta (for reasonable choices in temperature and opacity). A strong and relatively narrow O II $λ$7774 line, seen in a number of these energetic events but not in normal supernovae, may point to an inner shell that is the signature of a central engine.

description: A selection of new jet substructure measurements are reported from the ALICE experiment at the CERN LHC in both proton-proton and heavy-ion collisions. These include the first fully corrected inclusive measurements of the groomed jet momentum fraction and the groomed jet radius, as well as the $N$-subjettiness distribution and the fragmentation distribution of reclustered subjets. We also report on the measurement of several groomed substructure observables of heavy-flavor jets in pp collisions, fragmentation functions and the new measurements of the radial distributions of D$^0$ mesons or $Λ^+_c$ baryons in jets. The measurements are compared to theoretical calculations and provide new constraints on the physics underlying parton fragmentation and jet quenching.

description: This study was intended to assess the performance of land management service delivery of Nifas Silk Lafto Sub-City. For African countries, there is strong force in proper urban management which better achieve the increasing need for efficient and effective delivery of land administration services to protect the interest and security of urban citizens. As urban land administration is a comprehensive and important part of public service delivery, the concept of quality service gets worthwhile attentions. Therefore, this study assessed the land management service delivery performances in Nifas Silk Lafto sub city. The study is both descriptive and explanatory in its type. This research employed both qualitative and quantitative research methods to draw samples, collect data, analyse and interpret data. To portray sample from target population (citizens residue in NSL sub-city, land management office employees, officers and managers), the researcher adopted both simple random sampling and purposive sampling techniques. In the current land administration of Nifas Silk Lafto sub-city, customers have to consult various organizations/departments to get the service done. The title service delivery system is not only time taking but also expensive. As a result the urban poor is being pushed away not to use the service. Thus, these situations have created gaps between expectation of citizens and land administration service provided by the sub city land administration organization as more than half of the respondents did not receive efficient, equitable and accountable land services as per their expectations. Case study method, supporting literature review and hypothetical factors for quality service delivery adopted by World Bank (2005) and SERVQUAL Service Quality Model have been used as guidelines for the study. The case study has used 106 customer respondents and 30 employees and 6 managers as primary data source through questionnaires and interviews. The analysis of the data and information collected from the field work found out the performance and challenges of land service delivery as: inconsistency in land related legislations, inadequate resources and technical capabilities, not all lands are titled, lack of skilled and qualified man power, lack of public awareness, unclear land ownership. Based on the identified findings, conclusions are drawn and possible recommendations are made. Key Words: Land Management, Land Administration and Cadastral Map

description: We utilize the recent LHC-13 TeV data to study the lower mass bound on top-squark (stop) in natural supersymmetry. We recast the LHC sparticle inclusive search of $(\ge 1){\rm jets} + E^{miss}_T$ with $α_T$ variable, the direct stop pair search (1-lepton channel and all-hadronic channel) and the monojet analyses. We find that these searches are complementary depending on stop and higgsino masses: for a heavy stop the all-hadronic stop pair search provides the strongest bound, for an intermediate stop the inclusive SUSY analysis with $α_T$ variable is most efficient, while for a compressed stop-higgsino scenario the monojet search plays the key role. Finally, the lower mass bound on a stop is: (i) 320 GeV for compressed stop-higgsino scenario (mass splitting less than 20 GeV); (ii) 765 (860) GeV for higgsinos lighter than 300 (100) GeV.

description: We introduce an analogue model for a nonglobally hyperbolic spacetime in terms of a two-dimensional fluid. This is done by considering the propagation of sound waves in a radial flow with constant velocity. We show that the equation of motion satisfied by sound waves is the wave equation on $AdS_2\times S^1$. Since this spacetime is not globally hyperbolic, the dynamics of the Klein-Gordon field is not well defined until boundary conditions at the spatial boundary of $AdS_2$ are prescribed. On the analogue model end, those extra boundary conditions provide an effective description of the point source at $r=0$. For waves with circular symmetry, we relate the different physical evolutions to the phase difference between ingoing and outgoing scattered waves. We also show that the fluid configuration can be stable or unstable depending on the chosen boundary condition.

Efficiency of Electronic Service Delivery: A Case Study in Automated Systems for Customs Data (Asycuda) in Ethiopian Revenue and Customs Authority (ERCA)
Creators: name: Kubie, Kidist
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2010

description: This study aims to explore the efficiency of electronic service delivery by taking Automate System Customs Data (ASYCUDA) as the case study in Ethiopia Revenue and Customs Authority (ERCA). To conduct this study descriptive research methods were used. The study tried to describe the effiency of the system (ASYCUDA) by triangulating different ideas from the point views of customers, employees and other relevant office, which used ASYCUDA, processed datain their works. Asurvey has beenusedtocollect dataformthetotalof samplesizeof 194.Thesample of this study were chosen using systematic, purposive and non-random sampling. Questionnaires, interviews, data analysis and organization observations were used to collect necessary data. The research study involved three categories of sample population:customers of theorganization,employees of ERCA andrelevant office who directly used the report of ASYCUDA driven data. Data analysis was made by using SPSS version 17 software and other simple stastical tools like percentage, ratio and tables. The study finding indicate that even though ASYCUDA is facilitating the import and export process of the organization, it face implementation problems. This creates in effiency in the maximizations of the benefits expected from implementations of ASYCUDA. The major technical and institutional problems associated with were also analyzed. Some of the challenges, which create problems in smooth process of implementation of ASYCUDA, were: repeated system failure because of different reasons, frequent electronic power interruptions and These frequent failures of networks. create a big problem inimport and export process of the organization. From the analysis of the above problems through questionnaires and interviews, the study concludes that, these factors should be improved by creating coordination inside and outside of the organization to improve the efficiency of ASYCUDA which solve the problems of import and export process and make the revenue collection of ERCA very smooth. The study gives recommendations accordingly and some of the recommendations are: give training to employees reading ASYCUDA, using latest versions of ASYCUDA, improve managing system of the work process, improve the availability of network by coordinating with Ethiopian Telecommunications (ETC) and Ethiopian Electric Power Authority regardingelectric power failuresoruseother means to reduce the power interruptions at working hours

Risque infectieux

description: L’incidence des infections en chirurgie ambulatoire reste faible. Il faut néanmoins respecter la préparation cutanée avec une douche préopératoire et le délai requis pour l’administration de l’antibioprophylaxie. L’implication du patient concernant les règles d’hygiène après évaluation de sa vulnérabilité psycho-socio-environnementale est indispensable. Ces mesures sont d’autant plus indispensables que l’évolution de la chirurgie ambulatoire se fait vers des actes chirurgicaux plus complexes. Enfin, l’enjeu pour les grands plateaux interventionnels sera également le respect des règles d’hygiène, en particulier la tenue vestimentaire, le délai entre les patients et le respect de la fermeture de la porte du bloc opératoire.
