description: Placing bright sub-millimetre galaxies (SMGs) within the broader context of galaxy formation and evolution requires accurate measurements of their clustering, which can constrain the masses of their host dark matter halos. Recent work has shown that the clustering measurements of these galaxies may be affected by a `blending bias,' which results in the angular correlation function of the sources extracted from single-dish imaging surveys being boosted relative to that of the underlying galaxies. This is due to confusion introduced by the coarse angular resolution of the single-dish telescope and could lead to the inferred halo masses being significantly overestimated. We investigate the extent to which this bias affects the measurement of the correlation function of SMGs when it is derived via a cross-correlation with a more abundant galaxy population. We find that the blending bias is essentially the same as in the auto-correlation case and conclude that the best way to reduce its effects is to calculate the angular correlation function using SMGs in narrow redshift bins. Blending bias causes the inferred host halo masses of the SMGs to be overestimated by a factor of $\sim6$ when a redshift interval of $δz=3$ is used. However, this reduces to a factor of $\sim2$ for $δz=0.5$. The broadening of photometric redshift probability distributions with increasing redshift can therefore impart a mild halo `downsizing' effect onto the inferred host halo masses, though this trend is not as strong as seen in recent observational studies.

description: We show that the category of vector fields on a geometric stack has the structure of a Lie 2-algebra. This proves a conjecture of R.~Hepworth. The construction uses a Lie groupoid that presents the geometric stack. We show that the category of vector fields on the Lie groupoid is equivalent to the category of vector fields on the stack. The category of vector fields on the Lie groupoid has a Lie 2-algebra structure built from known (ordinary) Lie brackets on multiplicative vector fields of Mackenzie and Xu and the global sections of the Lie algebroid of the Lie groupoid. After giving a precise formulation of Morita invariance of the construction, we verify that the Lie 2-algebra structure defined in this way is well-defined on the underlying stack.

The well-known states that the threshold for the property G(n, p) -> (F, H) is equal to n(-1/)m(2)((F,H)), where m(2)(F, H) is given by m(2) (F, H) := max {e(J)/v(J) - 2 + 1/m(2)(H) : J subset of F, e(J) >= 1}. for any pair of graphs F and H with m(2) (F) >= m(2)(H).

description: The accurate determination of the maximum mass of the neutron stars is one of the most important tasks in astrophysics. It is directly related to the identification of the black holes in the universe, the production of neutron stars from the supernovae explosion, and the equation of state (EoS) of dense matter. However, not only the EoS is directly connected with neutron star masses, but also the speed of sound in dense matter is a crucial quantity which characterizes the stiffness of the EoS. The upper bound of the speed of sound imposes strong constraints on the maximum mass of neutron stars. However, this upper bound remains still an open issue. Recent observations, of binary neutron star systems, offer the possibility of measuring with high accuracy both the mass and the tidal polarizability of the stars. We study possible effects of the upper bound of the speed of sound on the upper bound of the mass and the tidal polarizability. We conclude that these kinds of measurements, combined with recent observations of neutron stars with masses close to $2 M_{\odot}$, will provide robust constraints on the equation of state of hadronic matter at high densities.

description: In the field of human resource management, training and development is one of the fields concerned with organizational activity aimed at improving the performance of individuals and groups in organizational settings. Training and development always plays an important role in employee performance improvement as well as the organization. This is because training and development and employee performance improvement is core factor in which managers should be keen in order to meet the organization's target. A descriptive research design with survey method is applied in this study. Using stratified random sampling technique, 297 participants (employees) of the organization were selected from a target population of 1971. The primary data was collected using standard questionnaires subject to subsequent analysis using SPSS version 20 software. Accordingly, training methods (r=.549** with p<0.05), Training evaluation (r=.597 with p<0.001) and training policies and procedures with (r=0.396, p<0.01) have a high degree of positive relationship with employee performance improvement. The expected outcome is aimed at detecting the need to motivate employees so as to improve their performance. The findings of the research generally reveal that training and development has a great deal of impact on employee performance improvement and the current training and development scheme is of satisfying to the employees per their response. The results imply that employees at CBE find training and development satisfying and yet some improvements in the training methods, evaluation and policy and procedure should be made per the researcher's observation.

description: The huge atomic heterogeneity of high-entropy materials along with a possibility to unravel the behavior of individual components at the atomic scale suggests a great promise in designing new compositionally complex systems with the desired multi-functionality. Herein, we apply multi-edge X-ray absorption spectroscopy (extended X-ray absorption fine structure (EXAFS), X-ray absorption near edge structure (XANES), and X-ray magnetic circular dichroism (XMCD)) to probe the structural, electronic, and magnetic properties of all individual constituents in the single-phase face-centered cubic (fcc)-structured nanocrystalline thin film of Cr20Mn26Fe18Co19Ni17 (at.%) high-entropy alloy on the local scale. The local crystallographic ordering and component-dependent lattice displacements were explored within the reverse Monte Carlo approach applied to EXAFS spectra collected at the K absorption edges of several constituents at room temperature. A homogeneous short-range fcc atomic environment around the absorbers of each type with very similar statistically averaged interatomic distances (2.54–2.55 Å) to their nearest-neighbors and enlarged structural relaxations of Cr atoms were revealed. XANES and XMCD spectra collected at the L2,3 absorption edges of all principal components at low temperature from the oxidized and in situ cleaned surfaces were used to probe the oxidation states, the changes in the electronic structure, and magnetic behavior of all constituents at the surface and in the sub-surface volume of the film. The spin and orbital magnetic moments of Fe, Co, and Ni components were quantitatively evaluated. The presence of magnetic phase transitions and the co-existence of different magnetic phases were uncovered by conventional magnetometry in a broad temperature range.

description: We report the detection of diffuse Ly$α$ emission, or Ly$α$ halos (LAHs), around star-forming galaxies at $z\approx3.78$ and $2.66$ in the NOAO Deep Wide-Field Survey Boötes field. Our samples consist of a total of $\sim$1400 galaxies, within two separate regions containing spectroscopically confirmed galaxy overdensities. They provide a unique opportunity to investigate how the LAH characteristics vary with host galaxy large-scale environment and physical properties. We stack Ly$α$ images of different samples defined by these properties and measure their median LAH sizes by decomposing the stacked Ly$α$ radial profile into a compact galaxy-like and an extended halo-like component. We find that the exponential scale-length of LAHs depends on UV continuum and Ly$α$ luminosities, but not on Ly$α$ equivalent widths or galaxy overdensity parameters. The full samples, which are dominated by low UV-continuum luminosity Ly$α$ emitters ($M_{\rm UV} \gtrsim -21$), exhibit LAH sizes of 5$\,-\,6\,$kpc. However, the most UV- or Ly$α$-luminous galaxies have more extended halos with scale-lengths of 7$\,-\,9\,$kpc. The stacked Ly$α$ radial profiles decline more steeply than recent theoretical predictions that include the contributions from gravitational cooling of infalling gas and from low-level star formation in satellites. On the other hand, the LAH extent matches what one would expect for photons produced in the galaxy and then resonantly scattered by gas in an outflowing envelope. The observed trends of LAH sizes with host galaxy properties suggest that the physical conditions of the circumgalactic medium (covering fraction, HI column density, and outflow velocity) change with halo mass and/or star-formation rates.

description: We consider the robust exponential utility maximization problem in discrete time: An investor maximizes the worst case expected exponential utility with respect to a family of nondominated probabilistic models of her endowment by dynamically investing in a financial market, and statically in available options. We show that, for any measurable random endowment (regardless of whether the problem is finite or not) an optimal strategy exists, a dual representation in terms of (calibrated) martingale measures holds true, and that the problem satisfies the dynamic programming principle (in case of no options). Further it is shown that the value of the utility maximization problem converges to the robust superhedging price as the risk aversion parameter gets large, and examples of nondominated probabilistic models are discussed.

A comparative analysis of 'high' and 'low' performance government institutions at MACRO, MESO and MICRO levels in oromia regional state against high performance factors
Creators: name: Kebede, Geneti
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: High performance government is vital for all countries; but more than any other things for developing countries like Ethiopia in general and Oromia Regional State in particular where much is expected from government to play custodian role, producer role, midwife role and husbandry role in line with self-declared democratic developmental state. High performance government in turn depends on high-performing public organizations, high performance teams and high performing individual public servants. In effect, this dissertation is aimed at assessing the status of high performance practices of public entities at four tiers; namely government-wide, public organizations, teams and individuals through comparative analysis of the reported high performance and low performance categories. To this end, descriptive-inferential and mixed research approach are used to describe the status of high performance practices at each level and test existence of statistically significant difference between the reported high performance and low performance ones based on primary and secondary data collected through document analysis, questionnaires and interview. In order to carry out these analyses, primary data were collected from 851 leaders categorized as high performance and low performance, 487 public servants from high performance and low performance sectors and 748 beneficiaries at service stations and public meetings and trainings; as well as 54 interviewees comprising of sector heads and deputy heads and member of the Caffee Oromia Standing Committee. The finding showed that government wide system designs are rated positively, while core management functions, accountability status, status of regional government capacity to deliver and status of public trust are all rated negatively. In connection with comparison of high performance and low performance public organizations there is statistically significant difference between the two in terms of leadership quality, organizational system quality, human resource quality, public service performance quality and citizens-public sectors partnership quality. By the same token, there is also statistically significant difference between high performance and low performance team concerning team objectives, team values and team roles. Finally, there is statistically significant difference between high performance and low performance public servants pertaining to competency, attitude, ethics and outlook. It is therefore recommended that political will, public will and organizational will should be raised and integrated; as well as hardware(institutions) and software(human) should be transformed towards creating and sustaining high performance government system in the region.

description: We classify singularities in FRW cosmologies, which dynamics can be reduced to the dynamical system of the Newtonian type. This classification is performed in terms of geometry of a potential function if it has poles. At the sewn singularity, which is of a finite scale factor type, the singularity in the past meets the singularity in the future. We show, that such singularities appear in the Starobinsky model in $f(\hat{R})=\hat{R}+γ\hat{R}^2$ in the Palatini formalism, when dynamics is determined by the corresponding piece-wise smooth dynamical system. As an effect we obtain a degenerated singularity. Analytical calculations are given for the cosmological model with matter and the cosmological constant. The dynamics of model is also studied using dynamical system methods. From the phase portraits we find generic evolutionary scenarios of the evolution of the Universe. For this model, the best fit value of $Ω_γ=3γH_0^2$ is equal $9.70\times 10^{-11}$. We consider model in both Jordan and Einstein frames. We show that after transition to the Einstein frame we obtain both form of the potential of the scalar field and the decaying Lambda term.

description: Between 2018-2022, there was a significant surge of venture capital in Agtech. The causes were many: the rise in global population and its consequences, AgTech developments themselves, the search for new investment sectors by VCs themselves, and even the pandemic all played a part. The surge brought investment to locations that hitherto had been completely outside the VC radar, notably Asia but now also Africa. Now that the surge has ebbed, along with VC investment as a whole, it is possible to begin to take stock. The evidence to date suggests that the majority of investment during the surge has flowed into downstream companies with the opportunity for rapid growth and high valuations. No global champion has yet emerged for upstream AgTech, whether in plant genetics, animal health or even novel farming systems. The impact of the surge in raising yields therefore rests on exits to or partnerships with major corporates, as they have the capacity to deliver technology at scale.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: The main purpose of this research is to examine the challenges of BSC implementing in performance appraisal on Enterprise Division in ethio-telecom. The data were collected using a questionnaire and semi-structured interview question from a sample population in Enterprise Division. From the total of 170 target population, this research selected 119 samples and collected data after that analyzed by using SPSS version 20 for the close-ended question. Then the data presented using descriptive statistics with the help of frequency, tables, and percentage to provide information. Mean and Standard Deviation through a measure of central tendency was also used to analyze data. The data that were collected by semi-structured interview questions and open-ended questions, interpreted manually. The result shows that the major challenges of BSC implementation in performance appraisal were, even if the staff discussed performance appraisal with their supervisors most of the time their idea is not acceptable. This leads to a disagreement between the staff and the supervisors. Most of the staffs are not satisfied by BSC implementation and the respondents state different reasons for this like BSC most of the time focused on countable factors, does not consider the weakness of the company rather focus only employees side, when the plan given it is not equally distributed between divisions this creates bias and the parameter (criteria) does not consider the working environment. The availability of enough resource take the highest share to achieve any target but the finding clearly indicated that there is no enough resource available to achieve the target. Performance progress is not monitored continuously before formal evaluation made this leads not to know the performance continuously. Therefore, future researchers may conduct for further related research work that covers a wider scope and larger sample size appears to be significant

description: Often, when dealing with real-world recognition problems, we do not need, and often cannot have, knowledge of the entire set of possible classes that might appear during operational testing. In such cases, we need to think of robust classification methods able to deal with the "unknown" and properly reject samples belonging to classes never seen during training. Notwithstanding, existing classifiers to date were mostly developed for the closed-set scenario, i.e., the classification setup in which it is assumed that all test samples belong to one of the classes with which the classifier was trained. In the open-set scenario, however, a test sample can belong to none of the known classes and the classifier must properly reject it by classifying it as unknown. In this work, we extend upon the well-known Support Vector Machines (SVM) classifier and introduce the Open-Set Support Vector Machines (OSSVM), which is suitable for recognition in open-set setups. OSSVM balances the empirical risk and the risk of the unknown and ensures that the region of the feature space in which a test sample would be classified as known (one of the known classes) is always bounded, ensuring a finite risk of the unknown. In this work, we also highlight the properties of the SVM classifier related to the open-set scenario, and provide necessary and sufficient conditions for an RBF SVM to have bounded open-space risk.

description: We present a novel data structure for searching sequences in large databases: the Hierarchical Interleaved Bloom Filter (HIBF). It is extremely fast and space efficient, yet so general that it could serve as the underlying engine for many applications. We show that the HIBF is superior in build time, index size, and search time while achieving a comparable or better accuracy compared to other state-of-the-art tools. The HIBF builds an index up to 211 times faster, using up to 14 times less space, and can answer approximate membership queries faster by a factor of up to 129.

description: The purpose of this study is to investigate project Implementation challenges and identify possible remedial actions for projects under carried by a local NGO called TaYA. Despite the different project implementation challenges NGOs in Ethiopia face there is a lack of sufficient published studies that document and address these challenges. Therefore, this study is conducted to contribute towards minimizing this gap. The research design is exploratory and descriptive while the sampling technique is purposive. Participants of the study are all program division staff of the organization and data is collected through in-depth interview, close and open-ended questionnaires and document analysis. The analysis is done qualitatively by relating the results with literatures and quantitatively using percentage, frequency and mean. The findings of the study revealed that lack of top management commitment, uncontrolled change to baseline requirement, lack of communication, inadequate tracking and directing of project activities, lack of Monitoring and Evaluation (M&E) system, high uncertainty, lack of accountability & completion criteria, CSO 70/30 policy, schedule pressure, being kept uninformed, unclear expectation, none collaborating functional areas, and staff turnover were the serious challenges the organization face during project implementation. These data support the view that TaYA is vulnerable to most of the challenges due to the traditional approach it adopts for project implementation and its high dependability on donors from abroad. Therefore, to alleviate these prevailing implementation challenges the organization should adopt a standard Project Management (PM) methodology for its projects, diversify funding partners, and conduct need assessment of beneficiaries. Furthermore, it needs to adopt well-structured communication strategy and invest more on the capacity building of its staff.

description: We consider the problem of efficient "on the fly" tuning of existing, or {\it legacy}, Artificial Intelligence (AI) systems. The legacy AI systems are allowed to be of arbitrary class, albeit the data they are using for computing interim or final decision responses should posses an underlying structure of a high-dimensional topological real vector space. The tuning method that we propose enables dealing with errors without the need to re-train the system. Instead of re-training a simple cascade of perceptron nodes is added to the legacy system. The added cascade modulates the AI legacy system's decisions. If applied repeatedly, the process results in a network of modulating rules "dressing up" and improving performance of existing AI systems. Mathematical rationale behind the method is based on the fundamental property of measure concentration in high dimensional spaces. The method is illustrated with an example of fine-tuning a deep convolutional network that has been pre-trained to detect pedestrians in images.

description: We prove a mass-angular momentum-charge inequality for a broad class of maximal, asymptotically flat, bi-axisymmetric initial data within the context of five-dimensional minimal supergravity. We further show that the charged Myers-Perry black hole initial data are the unique minimizers. In addition, we establish a rigidity statement for the relevant BPS bound, and give a variational characterization of BMPV black holes.
