description: We present a microscopic theory of nonlinear damping and dephasing of low-frequency eigenmodes in nano- and micro-mechanical systems. The mechanism of the both effects is scattering of thermally excited vibrational modes off the considered eigenmode. The scattering is accompanied by energy transfer of $2\hbarω_0$ for nonlinear damping and is quasieleastic for dephasing. We develop a formalism that allows studying both spatially uniform systems and systems with a strong nonuniformity, which is smooth on the typical wavelength of thermal modes but not their mean free path. The formalism accounts for the decay of thermal modes, which plays a major role in the nonlinear damping and dephasing. We identify the nonlinear analogs of the Landau-Rumer, thermoelastic, and Akhiezer mechanisms and find the dependence of the relaxation parameters on the temperature and the geometry of a system.

description: This paper aims to quantitatively evaluate the training performance of each XR modalities in general and in terms of the medical fields studied and outcomes measured. Face, content validation, and construct validation of the modalities of VR, AR, and MR training with the peg transfer, blood vessel cutting, and rope perforation were evaluated to the competition. Through subjective and objective evaluation, the potential promoting effects of vision and touch in module training were discussed. Using the entropy method to process the data obtained in the experiment, through calculations, the three modules of peg transfer, vessel cutting, and rope are calculated. The skills of doctors using VR training are improved by 17.71%, 17.83%, and 17.71% respectively. The skills of doctors using AR training are improved by 15.16%, 17.47%, and 16.41% respectively. With the MR training, the skills of doctors are improved by 21.77%, 22.74, and 19.84%. We can conclude that after using MR training, skill improvement is the highest, followed by VR and AR.

Determinants of Dividend payout: An Empirical Study on Bank Industry in Ethiopia
Creators: name: Kinfe, Theodros
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: This paper aimed at investigating the factors determining dividend payout policy in Ethiopia bank industry. This study used a panel dataset of audited financial statement of banks between the years of 2006 and 2010. Seven hypotheses were investigated using OLS regression techniques. The models considered the impact of profitability, liquidity, leverage, firm size, growth, and lagged dividend per share on dividend payout ratios. Empirical results verified that the main characteristics of firm dividend payout policy were that dividend payments related strongly and directly to firm size and lagged dividend per share, but negatively to the liquidity ratio. However, there is no relationship of profitability, leverage, and growth as independent variables with dividend payout. The statistically significant variables may indicate that firms pay dividends with the intention of reducing the agency problem. Mangers are reluctant to cut dividend. And, negative relation of liquidity with dividend may indicate inefficient of bank industry. The results of this study have delivered some insights on the determinant factors of dividend in Ethiopia. Keywords: dividend policy, irrelevant theorem, bird-in-hand theory, tax preference theory, agency conflict and signaling mechanism

description: Network couplings of oscillatory large-scale systems, such as the brain, have a space-time structure composed of connection strengths and signal transmission delays. We provide a theoretical framework, which allows treating the spatial distribution of time delays with regard to synchronization, by decomposing it into patterns and therefore reducing the stability analysis into the tractable problem of a finite set of delay-coupled differential equations. We analyse delay-structured networks of phase oscillators and we find that, depending on the heterogeneity of the delays, the oscillators group in phase-shifted, anti-phase, steady, and non-stationary clusters, and analytically compute their stability boundaries. These results find direct application in the study of brain oscillations.
Attachment Security, Environmental Adversity, and Fast Life History Behavioral Profiles in Human Adolescents

Publisher: name: Open Science Framework
Year: 2023
Subjects: subject: Social and Behavioral Sciences

description: The coupling between extrinsic mortality and fast life history (LH) rests on the assumption that organisms’ internal traits and states are unrelated to their external environments. In reality, animals react to extrinsic mortality conditions as functions of their intrinsic vitality, which includes physical and mental states. This study investigated attachment as an internal mental state in mediating and moderating the association between external adversity and fast LH behavioral profile. A sample of 1169 adolescents (51% girls) from 9 countries was observed for 8 years from age 10. The results confirm both mediation and moderation and, for moderation, secure attachment nullified and insecure attachment maintained the environment-LH coupling. These findings suggest that attachment may contribute to the slowing of human LH.

description: We report on the mechanical properties of few-layer black phosphorus (BP) nanosheets, in high vacuum and as a function of time of exposure to atmospheric conditions [1]. BP flakes with thicknesses ranging from 4 to 30 nm suspended over circular holes are characterized by nanoindentations using an atomic force microscope tip. From measurements in high vacuum an elastic modulus of 46+/-10 GPa and breaking strength of 2.4+/-1 GPa are estimated. Both magnitudes are independent of the thickness of the flakes. Our results show that the exposure to air has substantial influence in the mechanical response of flakes thinner than 6 nm but small effects on thicker flakes.

description: We present the results of the first model electrode study, where the geometryindependent relations between polarisation resistance (Rp) of Ba0.5La0.5CoO6-δ (BLC) and T, pO2 and pH2O have been extracted. The results are used as inputs in a model for quantifying the partial contributions to electrode polarization from oxide ions and protons, and the mediation of polarization by partial transport of electrode holes in a non-faradaic current. The model is fitted to – and exemplified through – a detailed analysis of the Rp of a brush-painted 3x3 mm BLC electrode on a BaZr0.4Ce0.4Y0.2O2.9 (BZCY442) electrolyte. The model may be used as input in higher-level system models, where the efficiency losses under static operation over the cell in electrolysis or fuelcell mode can be linked to materials-specific parameters for electrode or electrolyte materials. The model may also incorporate lower-level input from atomistic modelling to give predictive power to materials development and tailoring of functional properties relevant for anodic, cathodic or reversible operation. This delivery is a first step towards a full electrochemical model, where the direct relation between dynamic overpotential and current will be given in an analytical soloution. The study is undertaken on a brush-painted 3x3 mm BLC electrode as a pre-study for the upcoming geometry-resolved model electrode study which will reveal the extension of the reaction zone in x, y and z directions under increasing positive and negative DC bias. The large test-matrix give information of rate-determining reaction steps and the activation energies for protons and oxide ions across these steps for an electrode material with low proton- and high electronic conductivity. Verification of the experimental set-up will form the basis for further electrode characterisation under DC conditions. Impedance characterisation under DC bias is challenging, and the effect of several cell configurations is therefore investigated. We herein report the results of a cell configuration using Pt as counter electrode (CE) with ø 1 cm. We continue with studying the effect of CE area and material, as the counter electrode may be expected to influence the relative transport of protons, oxide ions and electron holes under DC conditions. We will not report on the results of other cell configurations in this document. The results of the study with Pt CE is that the polarisation resistance at the working electrode in reversible operation (zero bias) is dominated by mass transfer for the anodic oxidation of water at high temperatures, and by mass transfer for the cathodic oxygen reduction at low temperatures.

description: The inner regions of the envelopes surrounding young protostars are characterised by a complex chemistry, with prebiotic molecules present on the scales where protoplanetary disks eventually may form. This paper introduces a systematic survey, "Protostellar Interferometric Line Survey (PILS)" of the Class 0 protostellar binary IRAS 16293-2422 using the Atacama Large Millimeter/submillimeter Array (ALMA). The survey covers the full frequency range from 329 to 363 GHz (0.8 mm) with additional targeted observations at 3.0 and 1.3 mm. More than 10,000 features are detected toward one component in the protostellar binary. Glycolaldehyde, its isomers, methyl formate and acetic acid, and its reduced alcohol, ethylene glycol, are clearly detected. For ethylene glycol both lowest state conformers, aGg' and gGg', are detected, the latter for the first time in the ISM. The abundance of glycolaldehyde is comparable to or slightly larger than that of ethylene glycol. In comparison to the Galactic Center, these two species are over-abundant relative to methanol, possibly an indication of formation at low temperatures in CO-rich ices. Both 13C and deuterated isotopologues of glycolaldehyde are detected, also for the first time ever in the ISM. For the deuterated species, a D/H ratio of approximately 5% is found with no differences between the deuteration in the different functional groups of glycolaldehyde. Measurements of the 13C-species lead to a 12C:13C ratio of approximately 30, lower than the typical ISM value. This low ratio may reflect an enhancement of 13CO in the ice due to either ion-molecule reactions in the gas before freeze-out or differences in the temperatures where 12CO and 13CO ices sublimate. The results reinforce the importance of low-temperature grain surface chemistry for the formation of prebiotic molecules seen here in the gas after sublimation of the entire ice mantle.

Challenges and Prospects of Introducing Sustainable Microfinance Services in Afar Pastoral Population
Creators: name: Muhamed, Mesaud
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: Background: Afar regional state is one of the pastoral dominant livelihoods in the country. Like any other pastoralists Afar region was also neglected from developmental activities and services like microfinance institutions. The reason why such MFI did not exist in the region was not studied before. This study explores challenges and prospects of introducing sustainable microfinance services in the region focusing on the pastoral people. Objective: This study explores challenges and prospects of introducing sustainable microfinance services Afar pastoral population and the demand for the service. Methods: The study employed a mix of both quantitative and qualitative methodology employing semi structured and in-depth interviews with 60 pastoralists from two markets in zone one of Aysa"ita and Logia markets, 5 cooperative leaders from Aysa"ita woreda, and 8 key informants. The participants were selected from two markets (Logia and Aysaita) purposive sampling. Findings: Among the pastoralist sample, a substantial number of participants were found with high need for microfinance services at the same time with lack of awareness as how to diversify income generating activities. They show also a good habit of informal lending and borrowing with good repayment culture aided by clan based court (mablo). With regard to saving they are poor in saving but they show a need of formal MFIs for saving, money transfer, and credit services. NGO and government led cooperatives were not as such effective in their five years journey. The region has some specific constraints which increase cost of providing microfinance services to the pastoral community: such as harsh climate, highly dispersed settlement, poor infrastructure and socio economic conditions and other constraints. Interest issue is the most sensitive challenge observed from the study regarding failure of introducing MFI in the region. Conclusion: form the study it was concluded that there are specific constraints which could increase cost of providing services to the pastoralists. However, there are also compromising factors which help sustainable microfinance service like good demand and culture of repayment enforcement by the cultural court. Recommendation: Multi-faceted interventions on issues of income diversification and business skill of pastoralists should be carried out so as to create awareness about business, and so as to encourage need of the people for credit and saving services. Integration should be maintained with interventionists so as to cover operational costs and the product design should also cope with beneficiaries" culture

description: We study the structure of the zeros of optimal polynomial approximants to reciprocals of functions in Hilbert spaces of analytic functions in the unit disk. In many instances, we find the minimum possible modulus of occurring zeros via a nonlinear extremal problem associated with norms of Jacobi matrices. We examine global properties of these zeros and prove Jentzsch-type theorems describing where they accumulate. As a consequence, we obtain detailed information regarding zeros of reproducing kernels in weighted spaces of analytic functions.

description: We present analytical and numerical results regarding the magnetization full counting statistics (FCS) of a subsystem in the ground-state of the Haldane-Shastry chain. Exact Pfaffian expressions are derived for the cumulant generating function, as well as any observable diagonal in the spin basis. In the limit of large systems, the scaling of the FCS is found to be in agreement with the Luttinger liquid theory. The same techniques are also applied to inhomogeneous deformations of the chain. This introduces a certain amount of disorder in the system; however we show numerically that this is not sufficient to flow to the random singlet phase, that corresponds to $XXZ$ chains with uncorrelated bond disorder.

description: Field inspections to establish the frequency of occurrence and the length of sediment tongues around the boundaries of drainage lines of logged coupes on the granite soils in the Eden Woodchip Area, New South Wales showed that a sediment tongue occurs for every 0.5 km of drainage line but that sediment tongues penetrate to drainage lines on average once per 2.4 km of drainage line. When the lengths of sediment tongues are compared with the provisions for buffer strip width, it is concluded that, for slopes for up to 20*, a width of buffer strip of 20 metres is conservative. Associated studies of the source of sediment in sediment tongues, using the isotopes Cs-137 and Be-7, showed that the source of the sediment was almost entirely from the snig tracks. The methods used are promising for the study of sediment tongues.

description: The general eight-vertex model on a square lattice is studied numerically by using the Corner Transfer Matrix Renormalization Group method. The method is tested on the symmetric (zero-field) version of the model, the obtained dependence of critical exponents on model's parameters is in agreement with Baxter's exact solution and weak universality is verified with a high accuracy. It was suggested longtime ago that the symmetric eight-vertex model is a special exceptional case and in the presence of external fields the eight-vertex model falls into the Ising universality class. We confirm numerically this conjecture in a subspace of vertex weights, except for two specific combinations of vertical and horizontal fields for which the system still exhibits weak universality.

description: This thesis aimed to see the determinant factors for capital adequacy using 14 selected banks operating in Ethiopia from 2011 to 2015. The paper conducted different estimation to see the relationship between the dependent variable, Capital Adequacy Ratio (CAR) and independent Variables which include Bank size (SIZE), DAR (Deposit to Asset Ratio), Loan to Asset Ratio (LAR), Loan to Deposit (LTD), Return on Asset (ROA), Return on Equity (ROE), Loan Loss Provision (LPR), and macroeconomic variables (gross domestic product and inflation).The OLS regression result show that DAR, ROE, LPR and ROA are significant at one % of significant level; Size is significant at 5% of significant level whereas LAR is significant at 10 % of significant level. The variables SIZE, DAR, LAR and ROE affect CAR negatively whereas ROA and LPR affects positively. Hence, it is recommended that to be sure that banks have adequate adequacy reserve, commercial banks and National Bank of Ethiopia should give attention to the risk associated with banks size, caring of banks loan and deposit, initiating to increase their return on their asset and to manage their equity return

Hydrodynamic description of (visco)elastic composite materials and relative strains as a new macroscopic variable

description: One possibility to adjust material properties to a specific need is to embed units of one substance into a matrix of another substance. Even materials that are readily tunable during operation can be generated in this way. In (visco)elastic substances, both the matrix material as well as the inclusions and/or their immediate environment can be dynamically deformed. If the typical dynamic response time of the inclusions and their surroundings approach the macroscopic response time, their deformation processes need to be included into a dynamic macroscopic characterization. Along these lines, we present a hydrodynamic description of (visco)elastic composite materials. For this purpose, additional strain variables reflect the state of the inclusions and their immediate environment. These additional strain variables in general are not set by a coarse-grained macroscopic displacement field. Apart from that, during our derivation, we also include the macroscopic variables of relative translations and relative rotations that were previously introduced in different contexts. As a central point, our approach reveals and classifies the importance of a new macroscopic variable: relative strains. We analyze two simplified minimal example geometries as an illustration.

description: Real forms of a complex reductive group are classified by Galois cohomology H^1(Gamma,G_ad) where G_ad is the adjoint group. Cartan's classification of real forms in terms of maximal compact subgroups can be stated in terms of H^(Z/2Z,G_ad) where the action is by a (holomorphic) Cartan involution. The main result is that for any complex reductive group, possibly disconnected, there is a canonical isomorphism between H^1(Gamma,G) and H^1(Z/2Z,G). As applications we give short proofs of some well known results, including the Sekiguchi correspondence, Matsuki duality, results on Cartan subgroups, the rational Weyl group, and strong real forms. We also compute H^1(Gamma,G) for all simple, simply connected real groups.

description: As charge carriers traverse a single superconductor ferromagnet interface they experience an additional spin-dependent phase angle which results in spin mixing and the formation of a bound state called the Andreev Bound State. This state is an essential component in the generation of long range spin triplet proximity induced superconductivity and yet the factors controlling the degree of spin mixing and the formation of the bound state remain elusive. Here we demonstrate that point contact Andreev reflection can be used to detect the bound state and extract the resulting spin mixing angle. By examining spectra taken from La1.15Sr1.85Mn2O7 single crystal - Pb junctions, together with a compilation of literature data on highly spin polarised systems, we show that the existence of the Andreev Bound State both resolves a number of long standing controversies in the Andreev literature as well as defining a route to quantify the strength of spin mixing at superconductor-ferromagnet interfaces. Intriguingly we find that for these high transparency junctions, the spin mixing angle appears to take a relatively narrow range of values across all the samples studied. The ferromagnets we have chosen to study share a common property in terms of their spin arrangement, and our observations may point to the importance of this property in determining the spin mixing angle under these circumstances.

Year: 2010

description: This study entitled " Capital Investment Decisions On IT And Its Impact On Corporate Value Maximization " has investigated the impact of IT on profitability and cost efficiency in six private commercial banks. The overall objectives of the study was to evaluate the general trend of using project appraisal tools, the rationale to invest on IT and the impact of IT on profitability and cost efficiency. In order to evaluate these objectives five years of data has been collected from six private banks. The data has been collected from two sources: the primary data has been gathered through questionnaire and the secondary data has been obtained from the banks' published audited financial statements. In order to further strengthen the findings of this study the results has been tested by using t-test The findings of this study has revealed that with the exception of one bank all the remaining banks included in the survey have not used project appraisal tools to have an ex ante knowledge of the benefits and costs of IT investments. More over the rationale behind investing on IT was found to be strategic requirement (75%) and to be a leader in use of technology (50%) Evaluation of IT on the profitability and cost efficiency of high IT capital banks and the relatively low IT capital banks has been made by using key profit and cost ratios. The result of the study and the hypothesis testing have shown that high IT capital did not result in a significantly better profit and cost performance compared to the relatively low IT capital banks

Riparian ecosystems in the 21st century are likely to play a critical role in determining the vulnerability of natural and human systems to climate change, and in influencing the capacity of these systems to adapt. Some authors have suggested that riparian ecosystems are particularly vulnerable to climate change impacts due to their high levels of exposure and sensitivity to climatic stimuli, and their history of degradation. Others have highlighted the probable resilience of riparian ecosystems to climate change as a result of their evolution under high levels of climatic and environmental variability. We synthesize current knowledge of the vulnerability of riparian ecosystems to climate change by assessing the potential exposure, sensitivity, and adaptive capacity of their key components and processes, as well as ecosystem functions, goods and services, to projected global climatic changes. We review key pathways for ecological and human adaptation for the maintenance, restoration and enhancement of riparian ecosystem functions, goods and services and present emerging principles for planned adaptation. Our synthesis suggests that, in the absence of adaptation, riparian ecosystems are likely to be highly vulnerable to climate change impacts. However, given the critical role of riparian ecosystem functions in landscapes, as well as the strong links between riparian ecosystems and human well-being, considerable means, motives and opportunities for strategically planned adaptation to climate change also exist. The need for planned adaptation of and for riparian ecosystems is likely to be strengthened as the importance of many riparian ecosystem functions, goods and services will grow under a changing climate. Consequently, riparian ecosystems are likely to become adaptation ‘hotspots’ as the century unfolds.

description: A weighted difference of the $g$-factors of the Li- and H-like ion of the same element is studied and optimized in order to maximize the cancellation of nuclear effects. To this end, a detailed theoretical investigation is performed for the finite nuclear size correction to the one-electron $g$-factor, the one- and two-photon exchange effects, and the QED effects. The coefficients of the $Zα$ expansion of these corrections are determined, which allows us to set up the optimal definition of the weighted difference. It is demonstrated that, for moderately light elements, such weighted difference is nearly free from uncertainties associated with nuclear effects and can be utilized to extract the fine-structure constant from bound-electron $g$-factor experiments with an accuracy competitive with or better than its current literature value.

description: CARMENES (Calar Alto high-Resolution search for M dwarfs with Exoearths with Near-infrared and optical Echelle Spectrographs) started a new planet survey on M-dwarfs in January this year. The new high-resolution spectrographs are operating in the visible and near-infrared at Calar Alto Observatory. They will perform high-accuracy radial-velocity measurements (goal 1 m s-1) of about 300 M-dwarfs with the aim to detect low-mass planets within habitable zones. We characterised the candidate sample for CARMENES and provide fundamental parameters for these stars in order to constrain planetary properties and understand star-planet systems. Using state-of-the-art model atmospheres (PHOENIX-ACES) and chi2-minimization with a downhill-simplex method we determine effective temperature, surface gravity and metallicity [Fe/H] for high-resolution spectra of around 480 stars of spectral types M0.0-6.5V taken with FEROS, CAFE and HRS. We find good agreement between the models and our observed high-resolution spectra. We show the performance of the algorithm, as well as results, parameter and spectral type distributions for the CARMENES candidate sample, which is used to define the CARMENES target sample. We also present first preliminary results obtained from CARMENES spectra.

description: Using mechanical exfoliation combined with a controlled double step transfer procedure we demonstrate that single layers of antimony can be readily produced. These flakes are not significantly contaminated upon exposure to ambient conditions and they do not react with water. DFT calculations confirm our experimental observations and predict a band gap of 1.2-1.3 eV (ambient conditions) for single layer antimonene, which is smaller than that calculated under vacuum conditions at 0 K. Our work confirms antimonene as a highly stable 2D material with promising relevant applications in optoelectronics.

The Impact of Exchange Rate on the Profitability of Commercial Banks in Ethiopia
Creators: name: Getachew, Tadesse
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: As a financial intermediary, commercial banks are more exposed to the effect of exchange rate. Exchange rate can affect bank performance both directly and indirectly. The direct effect is easy to identify and can be easily managed. However, the indirect effect of exchange rate on the profitability of commercial banks is very subtle. Basically, it emanates from the impact of exchange rate on the business of bank clients and the economy in general. Therefore, knowing the aggregate impact of exchange rate on the profitability of banks is very crucial to device an appropriate coping strategy. This study, is therefore seek to examine the composite impact of exchange rate on the profitability (ROE) of commercial banks in Ethiopia using a balanced panel data set of banks over the period of 2000-2014. Furthermore, this study tried to determine how exchange rate affects the growth of bank loan with the intension to identify whether one of the indirect effect of exchange rate on bank profitability is through its effects on loan growth. The empirical findings of this study suggest that exchange rate has statistically significant negative impact on the profitability of commercial banks in Ethiopia. The result of the model estimated to examine the impact of exchange rate on loan growth of commercial banks in Ethiopia showed that exchange rate has statistically significant positive impact on the loan growth of banks in Ethiopia. Moreover, from the independent variables included as control variables in the regression analysis, loan growth rate and GDP growth are found to have statistically significant positive impact on bank profitability in Ethiopia, while loan loss expense ratio (Loan loss expense to total loan) is found to have statistically significant negative impact on bank profitability in Ethiopia. Similarly, from control variable included in the loan growth model, number of bank branches, lending interest rate and deposit to loan ratio are found to have statistically significant negative impact on the bank loan growth in Ethiopia. The study recommends that the bank managers and governing body shall focus on the composite effect of exchange rate variation on the bank profitability and make sure to avail appropriate strategy to reduce its adverse effect on the profitability of their bank.

description: Masser and Vaaler have given an asymptotic formula for the number of algebraic numbers of given degree $d$ and increasing height. This problem was solved by counting lattice points (which correspond to minimal polynomials over $\mathbb{Z}$) in a homogeneously expanding star body in $\mathbb{R}^{d+1}$. The volume of this star body was computed by Chern and Vaaler, who also computed the volume of the codimension-one "slice" corresponding to monic polynomials -- this led to results of Barroero on counting algebraic integers. We show how to estimate the volume of higher-codimension slices, which allows us to count units, algebraic integers of given norm, trace, norm and trace, and more. We also refine the lattice point-counting arguments of Chern-Vaaler to obtain explicit error terms with better power savings, which lead to explicit versions of some results of Masser-Vaaler and Barroero.
