description: A primary requirement for a robust and unconditionally secure quantum network is the establishment of quantum nonlocal correlations over a realistic channel. While loophole-free tests of Bell nonlocality allow for entanglement certification in such a device-independent setting, they are extremely sensitive to loss and noise, which naturally arise in any practical communication scenario. Quantum steering relaxes the strict technological constraints of Bell nonlocality by re-framing it in an asymmetric manner, thus providing the basis for one-sided device-independent quantum networks that can operate under realistic conditions. Here we introduce a noise-robust and loss-tolerant test of quantum steering designed for single detector measurements that harnesses the advantages of high-dimensional entanglement. We showcase the improvements over qubit-based systems by experimentally demonstrating detection loophole-free quantum steering in 53 dimensions through simultaneous loss and noise conditions corresponding to 14.2 dB loss equivalent to 79 km of telecommunication fibre, and 36% of white noise. We go on to show how the use of high dimensions counter-intuitively leads to a dramatic reduction in total measurement time, enabling a quantum steering violation almost two orders of magnitude faster obtained by simply doubling the Hilbert space dimension. By surpassing the constraints imposed upon the device-independent distribution of entanglement, our loss-tolerant, noise-robust, and resource-efficient demonstration of quantum steering proves itself a critical ingredient for making device-independent quantum communication over long distances a reality.

Year: 2018

description: This study emphasizes on the effect that social media has on the customer flow of the hotel industry. The objective of the study is to assess the impact of social media in contribution to customer flow of the hotel business in the country with special emphasis on the five-star hotels. Currently, social media networks and websites like Facebook, Twitter, LinkedIn and many more are redefining the way people communicate and share their travel and touring experiences. As a result, more and more companies are turning to these platforms to gather information, keep their customers informed about their products and so much more. In Ethiopia, however, the hotel industry heavily depends on conventional media for communication and advertising. The research has been conducted using explanatory research method since explanatory method is where a researcher has an idea or has observed something and seek to understand more about it. Sample size was calculated in the following formula and has come to be 214 respondents. Marketing managers of each five-star hotels in Addis Ababa i.e. seven Five-star hotels (Sheraton Addis, Capital International hotel, Ellily International Hotel, Radisson Blu Hotel, Golden Tulip Hotel, Getfam international Hotel and Marriot international Hotel) were the target for the study. The evidence from the collected data shows that each five-star hotel customers have been exposed to social media and they have been influenced by the information provided on the social media platforms including the information about the hotels services qualities, location, accommodation and price for using the services of the hotels. In advocacy, the engagement in social media has to be thought within the security framework of connectivity between the customers and Hotels. The issue of reliability about the information provided in the social media platform may have impact in reducing the customer flow of the Five Star Hotels. Therefore, both the customer and the Hotels has to think of ways that may secure their level of interaction in a mutually confirmed platform of social media protected by firewall and anti-fraudulent people.

description: In this work corrections to the usual flavor SU(2) Nambu-Jona-Lasinio coupling due to a weak external magnetic field are calculated by considering quark polarization in a (dressed) gluon exchange mechanism for quark interactions. The quark field is splitted into two components, one that condenses and another one that is a background field for interacting quarks, being the former integrated out. The resulting determinant is expanded for relatively large quark mass and small magnetic field, $(eB_0/{M^*}^2)<1$ by resolving magnetic field dependent low energy quark effective interactions. Besides the corrections for the NJL and vector NJL effective couplings, different $B_0-$dependent effective couplings that break isospin and chiral symmetry emerge.

description: Two formulations of relativistic hydrodynamics of particles with spin 1/2 are compared. The first approach, dubbed the canonical one, uses expressions for the energy-momentum and spin tensors that have properties that follow a direct application of Noether's theorem, which yields a totally antisymmetric spin tensor. The other one is based on a simplified form of the spin tensor and is commonly used in the current literature under the name of a phenomenological approach. We show that these two frameworks are equivalent, i.e., they can be directly connected by a suitably defined pseudogauge transformation, only if the first framework is initially improved by a suitable modification of the energy-momentum tensor (addition of a divergence-free term that cannot be interpreted as a pseudogauge). Our analysis uses arguments related to the positivity of entropy production. The latter turns out to be equivalent for the improved canonical and phenomenological frameworks.

description: In this work, we illustrate the recently introduced concept of the cavity Born-Oppenheimer approximation for correlated electron-nuclear-photon problems in detail. We demonstrate how an expansion in terms of conditional electronic and photon-nuclear wave functions accurately describes eigenstates of strongly correlated light-matter systems. For a GaAs quantum ring model in resonance with a photon mode we highlight how the ground-state electronic potential-energy surface changes the usual harmonic potential of the free photon mode to a dressed mode with a double-well structure. This change is accompanied by a splitting of the electronic ground-state density. For a model where the photon mode is in resonance with a vibrational transition, we observe in the excited-state electronic potential-energy surface a splitting from a single minimum to a double minimum. Furthermore, for a time-dependent setup, we show how the dynamics in correlated light-matter systems can be understood in terms of population transfer between potential energy surfaces. This work at the interface of quantum chemistry and quantum optics paves the way for the full ab-initio description of matter-photon systems.

description: We introduce a theoretical scheme for the analog quantum simulation of long-range XYZ models using current trapped-ion technology. In order to achieve fully-tunable Heisenberg-type interactions, our proposal requires a state-dependent dipole force along a single vibrational axis, together with a combination of standard resonant and detuned carrier drivings. We discuss how this quantum simulator could explore the effect of long-range interactions on the phase diagram by combining an adiabatic protocol with the quasi-periodic drivings and test the validity of our scheme numerically. At the isotropic Heisenberg point, we show that the long-range Hamiltonian can be mapped onto a non-linear sigma model with a topological term that is responsible for its low-energy properties, and we benchmark our predictions with Matrix-Product-State numerical simulations.

In this paper we show how these operators can be of use also for the removal of impulsive noise and to increase the stability of TDA in the presence of noisy data. In particular, we prove that GENEOs can control the expected value of the perturbation of persistence diagrams caused by uniformly distributed impulsive noise, when data are represented by $L$-Lipschitz functions from $\mathbb{R}$ to $\mathbb{R}$.

The Assessment of Good Urban Governance Practice in Land Administration of Addis Ababa: the Case of Yeka Sub-City
Creators: name: Aimro, Ashenafi
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Over the last decade, good governance has become a major area of focus by the government of Ethiopia. However, in reality most of public service institutions call for genuine practices of good governance. The service delivery of those institutions hindered due to the absence of good governance. The objective of the study is to assess the practice of good governance in land administration of Addis Ababa city administration Land Development and Management Office of Yeka sub city. This study tried to identify the perception of customers and employees towards the practice of good governance and customer satisfaction on the service provision of the sub city's Tenure administration and transitional period service office. Based on the perceptions that obtained from the respondents; the study tried to check on the relationship between the overall customer satisfaction on the office's service delivery and practice of good governance. In this research the tailored dimensions/principles of good governance are utilized on the Likert scale questionnaire. The five selected principles/dimensions of good governance were taken as variables of good governance. Additionally, to triangulate the responses of respondents qualitative data collected through key informants' interview and observation. To achieve the research objectives, both explanatory and descriptive research methods were applied. Therefore, the findings of the study revealed that the degradation of office's service quality has arises from unsatisfactory practice of good governance and/or inadequate quality of good governance of the office. Among the identified root causes of the office's customer service problems; the citizen charter of the bureau is not in function and most of customers have no idea about the citizen charter, there are inconsistencies on interpreting enacted legislations due to the absence of definite work procedure, the office didn't provide capacity building training and development schemes, the office did not respond promptly for customers' complaint and Customers at grass root level didn't get any opportunity to participate on developing and/or commenting plans, policies, and on evaluating final performances of the office. The study has also come up with important recommendations

description: Density-based and classification-based methods have ruled unsupervised anomaly detection in recent years, while reconstruction-based methods are rarely mentioned for the poor reconstruction ability and low performance. However, the latter requires no costly extra training samples for the unsupervised training that is more practical, so this paper focuses on improving this kind of method and proposes a novel Omni-frequency Channel-selection Reconstruction (OCR-GAN) network to handle anomaly detection task in a perspective of frequency. Concretely, we propose a Frequency Decoupling (FD) module to decouple the input image into different frequency components and model the reconstruction process as a combination of parallel omni-frequency image restorations, as we observe a significant difference in the frequency distribution of normal and abnormal images. Given the correlation among multiple frequencies, we further propose a Channel Selection (CS) module that performs frequency interaction among different encoders by adaptively selecting different channels. Abundant experiments demonstrate the effectiveness and superiority of our approach over different kinds of methods, e.g., achieving a new state-of-the-art 98.3 detection AUC on the MVTec AD dataset without extra training data that markedly surpasses the reconstruction-based baseline by +38.1 and the current SOTA method by +0.3.

Entanglement monotones and transformations of symmetric bipartite states
Creators: name: Girard, Mark W.
name: Gour, Gilad
Publisher: name: arXiv
Year: 2016
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The primary goal in the study of entanglement as a resource theory is to find conditions that determine when one quantum state can or cannot be transformed into another via local operations and classical communication. This is typically done through entanglement monotones or conversion witnesses. Such quantities cannot be computed for arbitrary quantum states in general, but it is useful to consider classes of symmetric states for which closed-form expressions can be found. In this paper, we show how to compute the convex roof of any entanglement monotone for all Werner states. The convex roofs of the well-known Vidal monotones are computed for all isotropic states, and we show how this method can generalize to other entanglement measures and other types of symmetries as well. We also present necessary and sufficient conditions that determine when a pure bipartite state can be deterministically converted into a Werner state or an isotropic state.

Redirective design politics: Attachments as sites of rupture
Creators: name: Zajzon, Noémi
Publisher: name: Loughborough University
Year: 2023
Subjects: Design not elsewhere classified

description: This study engages with the paradox that, by being inherently political, design simultaneously compartmentalises agency and secures participation through attachments to values that shape our identities. In social design, attachments are perceived as ontological associations that are leveraged for technical capacities and devices in social issues, but the affective values they circulate and the politics these may perpetuate remain unexplored. More existentialist views have charged design with displacing attachments by perpetuating renewal but stop short of understanding what attachments hold and secure. Drawing on three citizen-led political movements and organisations in Romania and Hungary, and employing theoretical resources from political and affect theories, science and technology and social movement studies, this thesis examines how design contributes to collective agency. By considering the role of attachments as a threshold for redirective practices, it explores the experience of participation by the collectives and the action potential they construct, in deliberate and spontaneous ways, to change the terms and conditions of participation within the political system. Insofar as attachments mobilise capacities, the citizen designer or design activist is also subject to the conditions revealed in this study. By deconstructing attachments through the intensities and effects, elements and moments that form the manifest content of design action, the study develops a framework through orientation within the affective register, guiding the reader through the sets of relations and the repertoires that iterate commitments between the individual and collective. The thesis contributes to critiques of design’s hegemonic epistemes that are embedded in liberal knowledge systems and that perpetuate the field’s critique in-and-of-itself, suggesting that the innate desires of design politics are subject to the contradictory promises held within attachments that settle a sense of democratic belonging, in this context through the nation state.
Ferroelectric tuning of superconductivity and band topology in a two-dimensional heterobilayer

description: Realization of tunable superconductivity with concomitant nontrivial band topology is conceptually intriguing and highly desirable for superconducting devices and topological quantum computation. Based on first-principles calculations, here we present the first prediction of simultaneously tunable superconducting transition temperature (Tc) and band topology in a superconducting IrTe2 overlayer on a ferroelectric In2Se3 monolayer. We first demonstrate that the Tc is substantially enhanced from that of IrTe2 nanoflakes (Tc ~3 K) due to significant charge repartitioning around the Fermi level. More importantly, the Tc is shown to sensitively depend on the In2Se3 polarization, with the higher Tc of ~(8-10) K attributed to enhanced interlayer electron-phonon coupling when the polarization is downward. The band topology is also switched from trivial to nontrivial as the polarization is reversed from upward to downward. These findings provide physically realistic platforms for simultaneously tuning superconductivity and band topology in two-dimensional heterobilayers and related heterostructures using a reversible and nonvolatile approach.

description: Fluctuations and correlations of conserved charges are sensitive observables for studying the QCD phase transition and critical point in high-energy heavy-ion collisions. We have studied the centrality and energy dependence of mixed-cumulants (up to fourth order) between net-baryon and net-strangeness in Au+Au collisions at $\sqrt{s_{NN}}$= 7.7, 11.5, 19.6, 27, 39, 62.4, 200 GeV from UrQMD model. To compare with other theoretical calculations, we normalize these mixed-cumulants by various order cumulants of net-strangeness distributions. We found that the results obtained from UrQMD calculations are comparable with the results from Lattice QCD at low temperature and hadron resonance gas model. The ratios of mixed-cumulants ($R_{11}^{BS},R_{13}^{BS},R_{22}^{BS}$,~$R_{31}^{BS}$) from UrQMD calculations show weak centrality dependence. However, the mixed-cumulant ratios $R_{11}^{BS}$ and $R_{31}^{BS}$ show strong increase at low energy, while the $R_{13}^{BS}$ snd $R_{22}^{BS}$ are similar at different energies. Furthermore, we have also studied the correlations between different hadron species and their contributions to the net-baryon and net-strangeness correlations. These models studies can provide baselines for searching for the signals of QCD phase transition and critical point in heavy-ion collisions.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: This research was conducted to study the relationship between performance levels of organizational value adding activities and profitability of selected leather products manufacturers in Addis Ababa based on the value chain model developed by Porter (1985). 35 different organizations were included in the study. Primary data from each of the organizations was collected through questionnaires. Secondary document analysis was also conducted by accessing financial and accounting records. Theoretical framework review and previous researches and studies in light of the current industry situation were used as an input for analysis and discussion of results. The data collected was descriptively analyzed through tabular summarization of the collected survey results, along with discussions. Correlation analysis was conducted to see how significant the associations of the value adding activities performance levels of the organizations are with their profitability. Furthermore, inferential statistics and hypothesis testing was undertaken in the form of median tests and ANOVA to test the assumption that difference in performance level in the organizational value adding activities determines the variability in profit margins of the organizations. Significant results were obtained from both the parametric and non parametric statistical tests. Correlation analysis results showed that the dependent and independent variables have positive and significant correlation. Also significant results from Analysis of variance taking operating profit margin of organizations as the response variable and performance levels of value adding activities as factors proved that organizational profitability is determined and depends on all primary and support value adding activities performance levels.

description: Associated abstract title: Most imported and locally sourced ryegrass seed lines contain plants resistant to Group 1 or 2 herbicidesRecent surveys revealed that >40% of New Zealand (NZ) vineyards and arable farms contain herbicideresistant plants. Resistant ryegrass (Lolium spp.) were particularly common. Multiplication of ryegrass provided NZ $80M in export revenues in 2021 but farmers suspected that cultivar seed-lines contained herbicide-resistant plants. We planted out seed from 56 distinct lots (28 per year) from 52 varieties, into 1.5 by 5 meter plots over two years, with four replicates per seed-lot and herbicide (336 randomized plots per year). Plots were treated with haloxyfop (Group 1), iodosulfuron (Group 2) and glyphosate at the highest recommended rate. Each herbicide was applied to approximately 30 to 80 thousand seedlings at the three-leaf stage, estimated survival rates were less than 2%. Eight weeks after treatment, up to 20 survivors were collected per variety and herbicide, grown in the glasshouse and tillered for respraying to confirm resistance to the herbicide treatments – because some plants could have been late germinators or somehow escaped exposure. Out of the 56 seed-lots (11 were from NZ, 45 were imported), resistance was confirmed for 44 lots, including some breeder’s lines. All NZ seed lots had resistant plants. Estimated resistance rates were between 1:20 and 1:70000, with seed lots classed as resistant to either haloxyfop (9 lots), iodsulfuron (10 lots) or both (25 lots), but none survived glyphosate. Some lines contained Poa annua that survived iodosulfuron as well. We speculate that resistance-conferring variants may occur normally in ryegrass at rates of 1:7000 or rarer, but 29 seed lots had higher rates.

description: We show that final state interactions (FSI) within a CPT invariant two-channel framework can enhance the charge-parity (CP) violation difference between $D^0\toπ^-π^+$ and $D^0\to K^-K^+$ decays up to the current experimental value. This result relies upon: (i) the dominant tree level diagram, (ii) the well-known experimental values for the $D^ 0\toπ^-π^+$ and $D^ 0\to K^-K^+$ branching ratios, and (iii) the $ππ\to ππ$ and $ππ\to K K $ scattering data to extract the strong phase difference and inelasticity. Based on well-grounded theoretical properties, we find the sign and bulk value of the $ΔA_{CP}$ and $A_{CP}(D^0 \to π^-π^+)$ recently observed by the LHCb Collaboration.

description: We present the results of a spectroscopic survey to characterize chromospheric activity, as measured by H$α$ emission, in low-mass members of the 500-Myr-old open cluster M37. Combining our new measurements of H$α$ luminosities ($L_{Hα}$) with previously cataloged stellar properties, we identify saturated and unsaturated regimes in the dependence of the $L_{Hα}$-to-bolometric-luminosity ratio, $L_{Hα}/L_{bol}$, on the Rossby number $R_o$. All rotators with Ro smaller than 0.03$\pm$0.01 converge to an activity level of $L_{Hα}/L_{bol}$ = (1.27$\pm$0.02) x 10$^{-4}$. This saturation threshold ($R_{o,sat}$ = 0.03$\pm$0.01) is statistically smaller than that found in most studies of the rotation-activity relation. In the unsaturated regime, slower rotators have lower levels of chromospheric activity, with $L_{Hα}/L_{bol}$($R_o$) following a power-law of index $β$ = -0.51$\pm$0.02, slightly shallower than the one found for a combined $\approx$650-Myr-old sample of Hyades and Praesepe stars. By comparing this unsaturated behavior to that previously found for coronal activity in M37 (as measured via the X-ray luminosity, $L_X$), we confirm that chromospheric activity decays at a much slower rate than coronal activity with increasing $R_o$. While a comparison of $L_{Hα}$ and $L_X$ for M37 members with measurements of both reveals a nearly 1:1 relation, removing the mass-dependencies by comparing instead $L_{Hα}/L_{bol}$ and $L_X/L_{bol}$ does not provide clear evidence for such a relation. Finally, we find that $R_{o,sat}$ is smaller for our chromospheric than for our coronal indicator of activity ($R_{o,sat}$ = 0.03$\pm$0.01 versus 0.09$\pm$0.01). We interpret this as possible evidence for coronal stripping.

description: تهدف هذه الدراسة إلى توضيح العلاقة بين الغاز الصخري باعتباره من أهم مصادر الطاقات التي أثارة الكثير من الجدل لدي الكثير من شعوب العالم وذلك للآثار الغير المرغوبة التي تحدثها في التنمية المستدامة بأبعدها المختلفة، وتوصلت الدراسة إلى أن علاقة الغاز الصخري بالتنمية المستدامة علاقة تعارض، بحيث يؤثر الغاز الصخري على البعد البيئي حيث يمس مخزون المياه والغلاف الجوي والطبقات التحتية للأرض، كما يؤثر الغاز الصخري على البعد الاجتماعي من خلال تلويث المياه الجوفية التي قد تؤثر على صحة الفرد مسببة أمراض خطيرة. بالإضافة إلى أن علاقة الغاز الصخري بالبعد الاقتصادي علاقة ضعيفة حيث أن عملية استخراج الغاز الصخري مبدئيا ليست مفيدة إلا بعد 30 سنة. وأوصت الورقة البحثية بضرورة استغلال الطاقات المتجددة بدلا من استغلال الغاز الصخري باعتبار الجزائر أول مخزن للطاقة الشمسية عالمية بمعدل يفوق 3000 ساعة شمسية سنويا "حسب دراسة ألمانية". أما إذا ما تم استغلال الغاز الصخري فمن الضروري استخدام أحدث التكنولوجيات للتخفيف من آثاره على الجانب البيئي والاجتماعي خاصة، بالإضافة إلى الاستفادة من التجربة الأمريكية خاصة في مجال استغلال الغاز الصخري. الكلمات المفتاحية: الغاز الصخري، التنمية المستدامة، البعد البيئي. This study aims at clarifying the relationship between rock gas as one of the most important sources of energies that have aroused much controversy among many peoples of the world due to the undesirable effects that it causes in sustainable development and the most different. The study concluded that the relation of rock gas to sustainable development Rock gas on the environmental dimension affects the water supply, the atmosphere and the underlying layers of the earth. Rock gas affects the social dimension by polluting underground water that may affect the health of the individual causing serious diseases. In addition, the relationship of shale gas to the economic dimension is weak since the extraction of shale gas in principle is not useful until 30 years. The paper recommended the use of renewable energies rather than the exploitation of shale gas as Algeria's first store of global solar energy at a rate of more than 3000 hours a year, "according to a German study. If rock gas is exploited, it is necessary to use the latest technology to mitigate its effects on the environmental and social aspects, in addition to benefiting from the American experience, especially in the exploitation of shale gas. Key words: rock gas, sustainable development, environmental dimension.

description: The formation of Middle Tropospheric Cyclones (MTCs) that are responsible for a large portion of annual precipitation and extreme rainfall events over western India is studied using an unsupervised machine learning algorithm and cyclone tracking. Both approaches reveal four dominant weather patterns that lead to the genesis of these systems; specifically, re-intensification of westward moving synoptic systems from Bay of Bengal (Type 1, 51%), in-situ formation with a coexisting cyclonic system over the Bay of Bengal that precedes (Type 2a, 31%) or follows (Type 2b, 10%) genesis in the Arabian Sea, and finally in-situ genesis within a northwestward propagating cyclonic anomaly from the south Bay of Bengal (Type 2c, 8%). Thus, a large fraction of rainy middle tropospheric synoptic systems in this region form in association with cyclonic activity in the Bay of Bengal. The four variants identified also show a marked dependence on large-scale environmental features with Type 1 and Type 2a formation primarily occurring in phases 4 and 5, and Type 2b and Type 2c in phases 3 and 4 of the Boreal Summer Intraseasonal Oscillation. Further, while in-situ formation with a Bay of Bengal cyclonic anomaly (Type 2a and 2b) mostly occurs in June, downstream development is more likely in the core of the monsoon season. Out of all categories, Type 2a is associated with the highest rain rate (60 mm/day) and points towards the dynamical interaction between a low pressure system over the Bay of Bengal and the development of MTCs over western India and the northeast Arabian Sea. This classification, identification of precursors, connection with cyclonic activity over the Bay of Bengal and dependence on large-scale environment provides an avenue for better understanding and prediction of rain-bearing MTCs over western India.

description: Embedded WENO methods utilize all adjacent smooth substencils to construct a desirable interpolation. Conventional WENO schemes under-use this possibility close to large gradients or discontinuities. We develop a general approach for constructing embedded versions of existing WENO schemes. Embedded methods based on the WENO schemes of Jiang and Shu (J. Comput. Phys. 126 (1996)) and on the WENO-Z scheme of Borges et al. (J. Comput. Phys. 227 (2008)) are explicitly constructed. Several possible choices are presented that result in either better spectral properties or a higher order of convergence for sufficiently smooth solutions. However, these improvements carry over to discontinuous solutions. The embedded methods are demonstrated to be indeed improvements over their standard counterparts by several numerical examples. All the embedded methods presented have no added computational effort compared to their standard counterparts.

description: In marketing, different tools are used to promote the product and make the consumer aware of it. Among all these tools, celebrity endorsement is one of the most emerging, successful and effective tool.Celebrity endorsement is an advertising strategy whereby companies use people of public recognition as spokespersons for their products. Today, the attitude, taste, preferences and buying pattern of consumers are changing rapidly and consumers are becoming more literate and aware of the products that they use to fulfill their needs and wants. Celebrity endorsement is a very successful and commonly practiced strategy for major firms to create and improve company's brand image Attractiveness, expertise, trustworthiness, and familiarity can contribute to celebrity endorsement and also use to measure celebrity endorsement. The main focus of this research paper is to examine the impacts of celebrity endorsement on customer's awareness and motivation towards the bank service. This study was limited on Ethiopian banks that implement celebrity endorsement as their marketing strategies these are: Awash international bank, Abyssinia bank, Bunna international bank, Commercial bank of Ethiopia, Oromia international bank, and Zemen bank were the focus area of the study.The researcher used explanatory research method in order to explain the impact of celebrity endorsement in creating awareness and motivating consumers towards buying their services. The target populations for the study were customers of the Ethiopian banking industry in Addis Ababa and have endorsed celebrities as a promotional strategy. Sample size was calculated as 400 is the appropriate sample size. The procedure of sampling for selecting sample respondents was multiple stage sampling. Data were collected from customers through a structured questionnaire prepared in both Amharic and English languages. Responses from the customers of the selected banks were filled in to computer and analyzed using SPSS software. The study utilized both descriptive statistical analysis and multiple regression analysis. The finding of the study shows that there is a direct and positive relationship between celebrity endorsement and customer motivation. The coefficients of the regression equation show that the independent variables (credibility and familiarity) have positive relationship with the dependent variable (Customer Awareness). While the independent variables (attractiveness and expertise) have negative relationship with dependent variable (customer awareness). On the other hand the coefficient of the regression equation shows that all the independent variables positive relationship with dependent variable (customer motivation).

description: Bismuth vanadate is one of most studied materials in the field of photocatalysis due to its high photocatalytic activity. The modulation of its optical properties can be engineered by fabricating photonic crystals in which bismuth vanadate is included. In the present study, bismuth vanadate in the monoclinic clinobisvanite structure has been included in a one-dimensional photonic crystal. Bismuth vanadate layers are alternated with layers on silicon dioxide doped with titanium dioxide nanoparticles and silver nanoparticles. The optical properties of the crystal have been studied by employing the transfer matrix method, taking into account all the refractive index dispersions of the selected materials. The transmission spectra have been studied as a function of the bismuth vanadate layers thickness and the filling factor of titanium dioxide and silver dioxide in the silicon dioxide layers.

description: In the brain, both neurons and glial cells work in conjunction with each other during information processing. Stimulation of neurons can cause calcium oscillations in astrocytes which in turn can affect neuronal calcium dynamics. The "glissandi" effect is one such phenomenon, associated with a decrease in infraslow fluctuations, in which synchronized calcium oscillations propagate as a wave in hundreds of astrocytes. Nitric oxide molecules released from the astrocytes contribute to synaptic functions on the basis of the underlying astrocyte-neuron interaction network. In this study, by defining an astrocyte-neuronal (A-N) unit as an integrated circuit of one neuron and one astrocyte, we developed a minimal model of neuronal stimulus-dependent and nitric oxide-mediated emergence of calcium waves in astrocytes. Incorporating inter-unit communication via nitric oxide molecules, a coupled network of 1,000 such A-N units is developed in which multiple stable regimes were found to emerge in astrocytes. We examined the ranges of neuronal stimulus strength and the coupling strength between A-N units that give rise to such dynamical behaviors. We also report that there exists a range of coupling strength, wherein units not receiving stimulus also start showing oscillations and become synchronized. Our results support the hypothesis that glissandi-like phenomena exhibiting synchronized calcium oscillations in astrocytes help in efficient synaptic transmission by reducing the energy demand of the process.

Dark Matter Relic Abundance and Light Sterile Neutrinos

description: In this paper, we calculate the relic abundance of the dark matter particles when they can annihilate into sterile neutrinos with the mass $\lesssim 100 \text{ GeV}$ in a simple model. Unlike the usual standard calculations, the sterile neutrino may fall out of the thermal equilibrium with the thermal bath before the dark matter freezes out. In such a case, if the Yukawa coupling $y_N$ between the Higgs and the sterile neutrino is small, this process gives rise to a larger $Ω_{\text{DM}} h^2$ so we need a larger coupling between the dark matter and the sterile neutrino for a correct relic abundance.
