description: A Jordan region is a subset of the plane that is homeomorphic to a closed disk. Consider a family $\mathcal{F}$ of Jordan regions whose interiors are pairwise disjoint, and such that any two Jordan regions intersect in at most one point. If any point of the plane is contained in at most $k$ elements of $\mathcal{F}$ (with $k$ sufficiently large), then we show that the elements of $\mathcal{F}$ can be colored with at most $k+1$ colors so that intersecting Jordan regions are assigned distinct colors. This is best possible and answers a question raised by Reed and Shepherd in 1996. As a simple corollary, we also obtain a positive answer to a problem of Hliněný (1998) on the chromatic number of contact systems of strings. We also investigate the chromatic number of families of touching Jordan curves. This can be used to bound the ratio between the maximum number of vertex-disjoint directed cycles in a planar digraph, and its fractional counterpart.

description: The purpose of this study was to assess the challenges and prospects of employee performance management system implemented in commercial Bank of Ethiopia. The study used descriptive method of study with cross sectional survey and used mixed research approach. This study has used stratified random sampling to select questionnaire respondents and purposive sampling to select interviewees. The research objectives were to assess the prospects and challenges of employee performance management system, to identify benefits gained from and challenges faced in implementing the system, to assess employees' perception towards employee performance management system and to evaluate performance management processes in the bank. Primary and secondary data were used. The analysis was done by the help of SPSS and presented using descriptive statistics; frequency tables, percentages, bar and pie charts. The scope of the study was limited to branches and head office within Addis Ababa area. The findings of the research indicated that employee performance management system has numerous benefits. Among them; it has created role clarity among employees, enables to differentiate good and poor performers, created a constructive competition among staffs. The system has also helps to motivate employees and encourage development through creating communications between the employees and their supervisor or managers. It improves both individual and the bank's overall performance. However the researcher has found that there were challenges; a tendency giving unbalanced goals for similar positions while they have equal job grades, no fair job rotation among employees, no sufficient resource allocation to execute their job properly, no clear mechanism in the bank to address the issue of underperformance, a tendency of giving 1 and 4 only for non financial targets. Furthermore, the result of evaluation did not attach with reward and recognition schemes. On the basis of the findings, the researcher recommended that the bank has to be making sure that equal jobs are assigned for equal positions, prevailing fair job rotation, attaching performance evaluation results with reward and recognition programs so that the issue of underperformance will be solved. The bank has also work with training of supervisors on assessment to make rating standard/uniform across assessors and branches/process Key words: Employee Performance Management system, commercial bank of Ethiopia, challenges and prospects.

description: In this letter we apply the Gauss--Bonnet theorem (GB) to calculate the deflection angle by a quantum corrected Schwarzschild black hole in the weak limit approximation. In particular we calculate the light deflection by two types of quantum corrected black holes: the renormalization group improved Schwarzschild solution and the quantum corrected Schwarzschild solution in Bohmian quantum mechanics. We start from the corresponding optical metrics to use then the GB theorem and calculate the Gaussian curvature in both cases. We calculate the leading terms of the deflection angle and show that quantum corrections modifies the deflection angle in both solutions. Finally by performing geodesics calculations we show that GB method gives exact results in leading order terms.

description: Sentence Ordering refers to the task of rearranging a set of sentences into the appropriate coherent order. For this task, most previous approaches have explored global context-based end-to-end methods using Sequence Generation techniques. In this paper, we put forward a set of robust local and global context-based pairwise ordering strategies, leveraging which our prediction strategies outperform all previous works in this domain. Our proposed encoding method utilizes the paragraph's rich global contextual information to predict the pairwise order using novel transformer architectures. Analysis of the two proposed decoding strategies helps better explain error propagation in pairwise models. This approach is the most accurate pure pairwise model and our encoding strategy also significantly improves the performance of other recent approaches that use pairwise models, including the previous state-of-the-art, demonstrating the research novelty and generalizability of this work. Additionally, we show how the pre-training task for ALBERT helps it to significantly outperform BERT, despite having considerably lesser parameters. The extensive experimental results, architectural analysis and ablation studies demonstrate the effectiveness and superiority of the proposed models compared to the previous state-of-the-art, besides providing a much better understanding of the functioning of pairwise models.

description: The behavior of stock market returns over a period of 1-60 days has been investigated for S&P 500 and Nasdaq within the framework of nonextensive Tsallis statistics. Even for such long terms, the distributions of the returns are non-Gaussian. They have fat tails indicating that the stock returns do not follow a random walk model. In this work, a good fit to a Tsallis q-Gaussian distribution is obtained for the distributions of all the returns using the method of Maximum Likelihood Estimate. For all the regions of data considered, the values of the scaling parameter q, estimated from one day returns, lie in the range 1.4 to 1.65. The estimated inverse mean square deviations (beta) show a power law behavior in time with exponent values between -0.91 and -1.1 indicating normal to mildly subdiffusive behavior. Quite often, the dynamics of market return distributions is modelled by a Fokker-Plank (FP) equation either with a linear drift and a nonlinear diffusion term or with just a nonlinear diffusion term. Both of these cases support a q-Gaussian distribution as a solution. The distributions obtained from current estimated parameters are compared with the solutions of the FP equations. For negligible drift term, the inverse mean square deviations (betaFP) from the FP model follow a power law with exponent values between -1.25 and -1.48 indicating superdiffusion. When the drift term is non-negligible, the corresponding betaFP do not follow a power law and become stationary after certain characteristic times that depend on the values of the drift parameter and q. Neither of these behaviors is supported by the results of the empirical fit.

Mitochondria represent the main source of energy of the cell generating ATP through the oxidative phosphorylation (OXPHOS). ATP is synthetised by F1-Fo ATPase (complex V) that uses the electrochemical gradient generated by the mitochondrial respiratory chain complexes to phosphorylate ADP. Many other roles have been proposed for complex V from maintaining cristae morphology to mitochondrial permeability transition. In the absence of mitochondrial membrane potential complex V can also hydrolyse ATP to pump H+ from the matrix in the inter membrane space pointing out how important its regulation can be for cell growth and survival. Both nuclear and mitochondrial genomes contribute to the biogenesis of this sophisticated molecular machinery; although the assembly, structure and function of the matrix part have been well understood in the past years, very little is known about the membrane part and its functions. 6.8 kDa Mitochondrial Proteolipid (MP68) is a small hydrophobic inner membrane protein that has been recently identified as a subunit of the membrane part of the vertebrate ATP synthase. I used CRISPR Cas9-mediated genome editing technology to investigate the role of this protein in F1-Fo ATPase assembly and function. I showed that MP68 knock out (KO) causes an increase in turnover of the membrane part of complex V as well as a defect in the assembly of the holocomplex with accumulation of various assembly intermediates in HEK293T cells. We also showed an increase in ATPase activity of isolated complex V suggesting a role of MP68 as part of the inhibitory mechanism that prevents the complex from hydrolysing ATP.

description: Training and development is an Investment rather than a cost to the organization. The utilization of all other resources directly depends on efficient utilization of human resources. Every organization needs to have well-trained and experienced people to perform the activities that have to be done. As jobs have become more complex in the banking sector, the importance of employee training and development has increased. A key for obtaining consistent success with training programs is to have a systematic approach to Training and development practices. Recognition of the Training and development of employees are crucial for the organization's success. This study deles with training and development of bank employees of CBE and AIB. It was carried out with a total sample of 160 employees drown from 16 branches of both CBE and AIB in Addis Ababa. A structured questionnaire is administered to all the respondents under the sample. certain aspects of training and development practices - Training policies and objectives, methods and Effects and benefits of the training of the banks. The finding of the study shows that there is no statistically significant difference and there is also a gap between the ideal training and development practice and the actual practices employed by the banks studied. Based on the finding the recommendation was put forward

description: We introduce and study some deformations of complete finite-volume hyperbolic four-manifolds that may be interpreted as four-dimensional analogues of Thurston's hyperbolic Dehn filling. We construct in particular an analytic path of complete, finite-volume cone four-manifolds $M_t$ that interpolates between two hyperbolic four-manifolds $M_0$ and $M_1$ with the same volume $\frac {8}3π^2$. The deformation looks like the familiar hyperbolic Dehn filling paths that occur in dimension three, where the cone angle of a core simple closed geodesic varies monotonically from $0$ to $2π$. Here, the singularity of $M_t$ is an immersed geodesic surface whose cone angles also vary monotonically from $0$ to $2π$. When a cone angle tends to $0$ a small core surface (a torus or Klein bottle) is drilled producing a new cusp. We show that various instances of hyperbolic Dehn fillings may arise, including one case where a degeneration occurs when the cone angles tend to $2π$, like in the famous figure-eight knot complement example. The construction makes an essential use of a family of four-dimensional deforming hyperbolic polytopes recently discovered by Kerckhoff and Storm.

description: Magnetic properties of a single vacancy in graphene is a relevant and still much discussed problem. The experimental results point to a clearly detectable magnetic defect state at the Fermi energy, while calculations based on density functional theory (DFT) yield widely varying results for the magnetic moment, in the range of $μ=1.04-2.0$ $μ_{B}$. We present a multi-tool \textit{ab initio} theoretical study of the same defect, using two simulation protocols for a defect in a crystal (cluster and periodic boundary conditions) and different DFT functionals - bare and hybrid DFT, mixing a fraction of Hartree-Fock exchange (XC). Our main conclusions are two-fold: First, we find that due to the $π$-character of the Fermi-energy states of graphene, inclusion of XC is crucial and for a single isolated vacancy we can predict an integer magnetic moment $μ=2μ_{B}$. Second, we find that due to the specific symmetry of the graphene lattice, periodic arrays of single vacancies may provide interesting diffuse spin-spin interactions.
Investigation of perforin pore function and formation
Creators: name: Stewart, Sarah Elizabeth
Publisher: name: Monash University

description: Cytotoxic lymphocytes eliminate virally infected or neoplastic cells through the action of cytotoxic proteases (granzymes). The pore-forming protein perforin is essential for delivery of granzymes into the cytoplasm of target cells. Perforin contains a membrane attack complex / perforin (MACPF) domain and oligomerises to form an aqueous pore in the plasma membrane. Therefore, the simplest (and best supported) model suggests that granzymes passively diffuse through the perforin pore into the cytoplasm of the target cell. However, the mechanics of pore assembly and granzyme delivery remain unclear. Perforin has been compared to Streptolysin O (SLO), a structurally similar bacterial pore-forming protein that is part of the cholesterol dependent cytolysin (CDC) family. The assembly of CDC pores has been extensively studied, and sets the paradigm for assembly of MACPF protein pores. This thesis comprehensively compares SLO and perforin in terms of cargo delivery and pore-forming mechanisms. Granzymes contain two cationic sites that have been previously shown to be important for delivery of human granzyme B by perforin. Human granzyme B contains the highest proportion of positive residues at these sites, while granzymes A and K both have fewer. It was shown that human and mouse granzyme A and K are delivered more efficiently by SLO than perforin. Human granzyme B, on the other hand, was delivered equally well with both perforin and SLO. These results reinforce the idea that positive residues are important for efficient delivery of granzymes by perforin, but not by SLO. Supporting this notion, it was found that perforin effectively delivered molecules other than granzymes, provided the cargo was cationic. Anionic and neutral molecules were inefficiently delivered by perforin. This suggests that perforin delivers cationic cargoes via “facilitated diffusion”, which may involve conserved features of oligomerised MACPF proteins, such as an anionic lumen. In a different approach, quartz crystal microbalance with dissipation monitoring (QCM-D) showed that the mechanism of pore formation of SLO is different to perforin. Perforin binding to membranes is cooperative whereas SLO binding follows first order kinetics. Cholesterol contributes to binding and activity of both SLO and perforin on intact cells and on model membranes. Finally, QCM-D revealed that perforin is able to efficiently bind membranes in the absence of calcium. When calcium was subsequently introduced the QCM-D traces changed significantly, indicating that perforin had bound calcium and then became active on the membrane. Taken together, these results demonstrate that there are fundamental differences between the cargo delivery and pore-forming mechanisms between MACPFs proteins and CDCs.

description: The main purpose of this study is to examine the effects of job satisfaction on employees' turnover intention in Cooperative Bank of Oromia S.C. The study is conducted using a sequential transformative mixed research approach with descriptive and explanatory research design. The primary date is collected using a self-administered structured questionnaire and interview with the employees of the bank. In addition secondary data is collected from the bank and related studies. The collected data were analyzed using descriptive statistics and multiple regressions. The correlation result revealed that the four job satisfaction factors are negatively and significantly related to turnover intention of employees'. Among the four job satisfaction factors, Pay satisfaction is the most predictor to turnover intention of employees' based on the regression result. The study recommends that the management of CBO should continuously examine and improve the existing HR policy and procedure on Pay and benefit structure which can guarantee continuous satisfaction of employees of the bank and to keep them retained in the bank

Scientists and engineers are continuously inventing and improving artificial intelligence (AI) to assist humans in many daily tasks. One of the most common technologies in automotive applications is the vision system that provides guidance to drivers to mitigate their lack of focus on road sign information. There is much vital information of which drivers need to be aware when negotiating through traffic. Drivers need to obey all road regulatory signs and pay attention to advisory signs. This presents a requirement for a vision system that can interpret text-based road signs and advise the drivers in a timely manner. The focus of this thesis is to develop a novel methodology to perform real-time Optical Character Recognition (OCR) on road signs as viewed by a forward facing camera to deliver necessary traffic sign information to drivers. Fundamentally, an field-programmable gate array (FPGA) with its concurrent architecture is an ideal platform to implement the system on. A feature extraction method using Haar-like features with an artificial neural network as classification has been developed to detect block letters on road signs. This neural network was trained using a comprehensive synthetic positive database formulated from a model letter set subjected to geometric mutations. Furthermore, a collection of optimization algorithms is proposed, implemented and demonstrated to facilitate the direct implementation of such a neural network on an FPGA platform. Finally, a fully working system is implemented and tested on an FPGA confirming full frame rate performance using live streaming video data.

description: Packet replication and elimination functions are used by time-sensitive networks (as in the context of IEEE TSN and IETF DetNet) to increase the reliability of the network. Packets are replicated onto redundant paths by a replication function. Later the paths merge again and an elimination function removes the duplicates. This redundancy scheme has an effect on the timing behavior of time-sensitive networks and many challenges arise from conducting timing analyses. The replication can induce a burstiness increase along the paths of replicates, as well as packet mis-ordering that could increase the delays in the crossed bridges or routers. The induced packet mis-ordering could also negatively affect the interactions between the redundancy and scheduling mechanisms such as traffic regulators (as with per-flow regulators and interleaved regulators, implemented by TSN asynchronous traffic shaping). Using the network calculus framework, we provide a method of worst-case timing analysis for time-sensitive networks that implement redundancy mechanisms in the general use case, i.e., at end-devices and/or intermediate nodes. We first provide a network calculus toolbox for bounding the burstiness increase and the amount of reordering caused by the elimination function of duplicate packets. We then analyze the interactions with traffic regulators and show that their shaping-for-free property does not hold when placed after a packet elimination function. We provide a bound for the delay penalty when using per-flow regulators and prove that the penalty is not bounded with interleaved regulators. Finally, we use an industrial use-case to show the applicability and the benefits of our findings.

description: We have investigated the longitudinal thermal conductivity of $α$-RuCl$_{3}$, the magnetic state of which is considered to be proximate to a Kitaev honeycomb model, along with the spin susceptibility and magnetic specific heat. We found that the temperature dependence of the thermal conductivity exhibits an additional peak around 100 K, which is well above the phonon peak temperature ($\sim$ 50 K). The higher-temperature peak position is comparable to the temperature scale of the Kitaev couplings rather than the Néel temperatures below 15 K. The additional heat conduction was observed for all five samples used in this study, and was found to be rather immune to a structural phase transition of $α$-RuCl$_{3}$, which suggests its different origin from phonons. Combined with experimental results of the magnetic specific heat, our transport measurement suggests strongly that the higher-temperature peak in the thermal conductivity is attributed to itinerant spin excitations associated with the Kitaev couplings of $α$-RuCl$_{3}$. A kinetic approximation of the magnetic thermal conductivity yields a mean free path of $\sim$ 20 nm at 100 K, which is well longer than the nearest Ru-Ru distance ($\sim$ 3 Å), suggesting the long-distance coherent propagation of magnetic excitations driven by the Kitaev couplings.

description: We introduce an unsupervised discriminative model for the task of retrieving experts in online document collections. We exclusively employ textual evidence and avoid explicit feature engineering by learning distributed word representations in an unsupervised way. We compare our model to state-of-the-art unsupervised statistical vector space and probabilistic generative approaches. Our proposed log-linear model achieves the retrieval performance levels of state-of-the-art document-centric methods with the low inference cost of so-called profile-centric approaches. It yields a statistically significant improved ranking over vector space and generative models in most cases, matching the performance of supervised methods on various benchmarks. That is, by using solely text we can do as well as methods that work with external evidence and/or relevance feedback. A contrastive analysis of rankings produced by discriminative and generative approaches shows that they have complementary strengths due to the ability of the unsupervised discriminative model to perform semantic matching.

description: Cosmic rays (CRs) are an important component in the interstellar medium (ISM), but their effect on the dynamics of the disk-halo interface (< 10 kpc from the disk) is still unclear. We study the influence of CRs on the gas above the disk with high-resolution FIRE-2 cosmological simulations of late-type Lstar galaxies at redshift around zero. We compare runs with and without CR feedback (with constant anisotropic diffusion around 3e29 cm^2/s and streaming). Our simulations capture the relevant disk halo interactions, including outflows, inflows, and galactic fountains. Extra-planar gas in all of the runs satisfies dynamical balance, where total pressure balances the weight of the overlying gas. While the kinetic pressure from non-uniform motion (>1-kpc scale) dominates in the midplane, thermal and bulk pressures (or CR pressure if included) take over at large heights. We find that with CR feedback, (1) the warm (1e4K) gas is slowly accelerated by CRs; (2) the hot (> 5e5K) gas scale height is suppressed; (3) the warm-hot (2e4-5e5K) medium becomes the most volume-filling phase in the disk-halo interface. We develop a novel conceptual model of the near-disk gas dynamics in low-redshift Lstar galaxies: With CRs, the disk-halo interface is filled with CR-driven warm winds and hot super-bubbles that are propagating into the CGM with a small fraction falling back to the disk. Without CRs, most outflows from hot superbubbles are trapped by the existing hot halo and gravity, so typically they form galactic fountains.

description: We consider the third quantization in quantum cosmology of a minisuperspace extended by the Eisenhart-Duval lift. We study the third quantization based on both Klein-Gordon type and Dirac-type equations in the extended minisuperspace. Spontaneous creation of "universes" is investigated upon the quantization of a simple model. We find that the quantization of the Dirac-type wave function reveals that the number density of universes is expressed by the Fermi-Dirac distribution. We also calculate the entanglement entropy of the multi-universe system.

description: We introduce and study several combinatorial properties of a class of symmetric polynomials from the point of view of integrable vertex models in finite lattice. We introduce the $L$-operator related with the $U_q(sl_2)$ $R$-matrix, and construct the wavefunctions and their duals. We prove the exact correspondence between the wavefunctions and symmetric polynomials which is a quantum group deformation of the Grothendieck polynomials. This is proved by combining the matrix product method and an analysis on the domain wall boundary partition functions. As applications of the correspondence between the wavefunctions and symmetric polynomials, we derive several properties of the symmetric polynomials such as the determinant pairing formulas and the branching formulas by analyzing the domain wall boundary partition functions and the matrix elements of the $B$-operators.

description: The study focused on the effect of training and development on employees' performance at the Ministry of Public Service and Human Resource Development. The overall objective of the study is to determine the effect of training and development on employees' performance. The study adopted mixed approach and used both primary and secondary data sources. The primary data collected from MOPSHRD through self administered questionnaire for 156 selected experts and middle level managers through simple random sampling technique and semi- structured interview question employed for human resource director and training coordinator through interview. The collected data were analyzed by using statistical tools (SPSS-Version 21). Both descriptive and inferential statistics were used for the data analysis. The descriptive statistics such as frequency, percent, mean and standard deviation were used for describing the demographic characteristics of respondents and the dependent and independent variables. The inferential statistics like Pearson correlation coefficient(r) and simple linear regression were used to determine if there is relationship existed between independent and dependent variables (training development and employees' performance. The findings indicated that training and development were positively correlated and claimed statistically significant relationship with employees' performance. The study concluded that training and development have positive effect on employees' performance. The findings of the study indicated that there was no sounding and effective training and development practices of the study' consequently the result disclosed the given training and development processes have been unsystematic. Hence, the researcher recommended that the top Management and other training coordinators should apply systematic and authentic training and development practices. Generally, the study recommended that training and development have to be strategic and systematic in order to achieve organizations desire and objective
