description: This work examines the dynamics of density patches in the 2D zero-diffusivity Boussinesq system modified such that momentum is in a large Prandtl number balance. We establish the global well-posedness of this system for compactly supported and bounded initial densities, and then examine the regularity of the evolving boundary of patch solutions. For $k \in \{0,1,2\}$, we prove the global in time persistence of $C^{k+μ}$-regularity, where $μ\in (0,1)$, for the density patch boundary via estimates of singular integrals. We conclude with a simulation of an initially circular density patch via a level-set method. The simulated patch boundary forms corner-like structures with growing curvature, and yet our analysis shows the curvature will be bounded for all finite times.

Invariant manifolds and the parameterization method in coupled energy harvesting piezoelectric oscillators
Creators: name: Granados, Albert
Publisher: name: arXiv
Year: 2016
Subjects: subject: Dynamical Systems (math.DS)
subject: FOS: Mathematics

description: Energy harvesting systems based on oscillators aim to capture energy from mechanical oscillations and convert it into electrical energy. Widely extended are those based on piezoelectric materials, whose dynamics are Hamiltonian submitted to different sources of dissipation: damping and coupling. These dissipations bring the system to low energy regimes, which is not desired in long term as it diminishes the absorbed energy. To avoid or to minimize such situations, we propose that the coupling of two oscillators could benefit from theory of Arnold diffusion. Such phenomenon studies $O(1)$ energy variations in Hamiltonian systems and hence could be very useful in energy harvesting applications. This article is a first step towards this goal. We consider two piezoelectric beams submitted to a small forcing and coupled through an electric circuit. By considering the coupling, damping and forcing as perturbations, we prove that the unperturbed system possesses a $4$-dimensional Normally Hyperbolic Invariant Manifold with $5$ and $4$-dimensional stable and unstable manifolds, respectively. These are locally unique after the perturbation. By means of the parameterization method, we numerically compute parameterizations of the perturbed manifold, its stable and unstable manifolds and study its inner dynamics. We show evidence of homoclinic connections when the perturbation is switched on.

Creators: name: Mulu, Adisu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: The purpose of this study is to assess the financial performance of microfinance institutions and the perception of their contribution for community development. The researcher used both qualitative and quantitative research approaches. Specifically, the study employs data obtained from a documentary review, a questionnaire survey and interviews through random and purposive sampling techniques respectively. The researcher chose 98 clients from ADCSI and 81 clients from OCSSCO through random sampling technique in Sendafa Bekie town and 60 clients from ADCSI in Yeka sub city wereda 11 branches through random sampling for the purpose of comparison. The study revealed that Addis credit and saving institution have achieved the outreach, return on equity, operational self-sufficiency and profitability. However, the institution has not achieved the portfolio quality, return on asset and efficiency for the last five years. Outreach, profitability, operational self-sufficiency, operational cost and return on equity of Oromiya credit and saving Share Company are improved over time. However, portfolio quality and Cost per borrower of Oromiya credit and saving Share Company is not improved. Also the results show that the living standards of the communities and business operations are perceived to be improved after they join the microfinance program in Sendafa Bekie town and Yeka sub city, but it is better in Yeka sub city. The main challenges while providing microfinance services are Shortage of skilled man power, failures of clients business, Loan default, limited portfolios and transportation problems during follow up. Finally, based on this study, it is recommended that MFIs should try to diversifying the microfinance program, offer enough capital to run their business and establish strong networks with governmental and non-governmental organizations to provide effective microfinance services to the poor communities in Sendafa Bekie town.

description: Understanding the effect of pinning on the vortex dynamics in superconductors is a key factor towards controlling critical current values. Large-scale simulations of vortex dynamics can provide a rational approach to achieve this goal. Here, we use the time-dependent Ginzburg-Landau equations to study thin superconducting films with artificially created pinning centers arranged periodically in hexagonal lattices. We calculate the critical current density for various geometries of the pinning centers --- varying their size, strength, and density. Furthermore, we shed light upon the influence of pattern distortion on the magnetic-field-dependent critical current. We compare our result directly with available experimental measurements on patterned molybdenum-germanium films, obtaining good agreement. Our results give important systematic insights into the mechanisms of pinning in these artificial pinning landscapes and open a path for tailoring superconducting films with desired critical current behavior.

description: We investigate emergence of spontaneous filtering of Brownian motion in higher dimensional space by many--body structures of symmetry broken dimer. Interacting dimer form structures which eventually restrict rotational degrees of freedom of individual constituents resulting in spontaneous emergence of collective transport. In this phenomenon, interaction and broken structural symmetry play cooperatively in emergence of collective transport out of thermal fluctuations. As a general phenomenon, spontaneous filtering of Brownian fluctuation might play an important role in the structural transition of complex molecules on top of what is known in terms of Kramers--rate process. This could also be a missing link to completely understand basics of bio--polymers' folding transitions (protein folding) where structure might encode motion in phase space.

Clues on the Majorana scale from scalar resonances at the LHC
Creators: name: Fischer, Oliver
Publisher: name: arXiv
Year: 2016
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: In order to address the observation of the neutrino oscillations and the metastability of the Standard Model, we extend the fermion sector with two right-handed (i.e. sterile) neutrinos, and the scalar sector of the SM with a real scalar, the Hill field. The latter takes the role of a Majoron and generates the Majorana masses for the neutrino sector, such that the particle spectrum features two CP-even scalars $h_1$ and $h_2$, and also two heavy, mass degenerate neutrinos. When the $h_1$ is identified with the scalar resonance at ~125 GeV and the condition is imposed that the $h_1$ self coupling and its running vanish at the Planck scale, the scalar mixing and the vacuum expectation value of the Hill field are fixed by the $h_2$ mass. The $h_2$ can be searched for at the LHC, and it has prospects of being discovered for the target integrated luminosities of the HL-LHC and the Future Circular hadron Collider (FCC-hh) when its mass is on the weak scale. The knowledge of the $h_2$ mass and its decay properties can yield an insight into its coupling to the heavy neutrinos, and thus also on the heavy neutrino mass scale. This yields an interesting connection between potentially detectable heavy scalars in high-energy proton collisions and the mass scale of the heavy neutrinos that is testable at the LHC and at future colliders.

description: Recently, there has been a growing interest in efficient numerical algorithms based on tensor networks and low-rank techniques to approximate high-dimensional functions and solutions to high-dimensional PDEs. In this paper, we propose a new tensor rank reduction method based on coordinate transformations that can greatly increase the efficiency of high-dimensional tensor approximation algorithms. The idea is simple: given a multivariate function, determine a coordinate transformation so that the function in the new coordinate system has smaller tensor rank. We restrict our analysis to linear coordinate transformations, which gives rise to a new class of functions that we refer to as tensor ridge functions. Leveraging Riemannian gradient descent on matrix manifolds we develop an algorithm that determines a quasi-optimal linear coordinate transformation for tensor rank reduction.The results we present for rank reduction via linear coordinate transformations open the possibility for generalizations to larger classes of nonlinear transformations. Numerical applications are presented and discussed for linear and nonlinear PDEs.

Determinants of Nonperforming Loans: Evidence from Commercial Banks in Ethiopia
Creators: name: Kibur, Minas
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: The aim this study is to examine three bank specific and three macroeconomic determinants of nonperforming loans proposed by the literature in the Ethiopian banking system for the period 2005 to 2013 using Arellano Bond (1991) first difference GMM estimation method. The three bank specific factors are ROA, capital to asset ratio and loan to deposit ratio and the three macroeconomic factors are real GDP growth, unemployment and inflation. The estimation result indicates that the coefficient of lagged dependent variable was between 0 and 1 as expected. Profitability and capital adequacy both showed significant (p<0.05) negative effect on NPL. Loan growth has also shown significantly (P<0.05) and positively effect on NPL. However the three macroeconomic factors have insignificant (p<0.1) effect on NPLs. The model was tested for over identification problem by Sargan test as recommended by Aellano Bond (1991). Further two autocorrelation test, AR (1) and AR (2) were conducted to test the assumption of no autocorrelations in the error term. The test result rejected the null hypotheses confirm the validity model assumptions. The results of the research benefit specifically bank managers and financial sector regulatory body.
Microscopic theory of Dzyaloshinsky-Moriya interaction in pyrochlore oxides with spin-orbit coupling
Creators: name: Arakawa, Naoya
Publisher: name: arXiv
Year: 2016
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: Pyrochlore oxides show several fascinating phenomena, such as the formation of heavy fermions and the thermal Hall effect. Although a key to understanding some phenomena may be the Dzyaloshinsky-Moriya (DM) interaction, its microscopic origin is unclear. To clarify the microscopic origin, we constructed a $t_{2g}$-orbital model with the kinetic energy, the trigonal-distortion potential, the multiorbital Hubbard interactions, and the $LS$ coupling, and derived the low-energy effective Hamiltonian for a $d^{1}$ Mott insulator with the weak $LS$ coupling. We first show that lack of the inversion center of each nearest-neighbor V-V bond causes the odd-mirror interorbital hopping integrals. Those are qualitatively different from the even-mirror hopping integrals, existing even with the inversion center. We next show that the second-order perturbation using the kinetic terms leads to the ferromagnetic and the antiferromagnetic super exchange interactions. Then, we show the most important result: the third-order perturbation terms using the combination of the even-mirror hopping integral, the odd-mirror hopping integral, and the $LS$ coupling causes the DM interaction due to the mirror-mixing effect, where those hopping integrals are necessary to obtain the antisymmetric kinetic exchange and the $LS$ coupling is necessary to excite the orbital angular momentum at one of two sites. We also show that the magnitude and sign of the DM interaction can be controlled by changing the positions of the O ions and the strength of the Hubbard interactions. We discuss the advantages in comparison with the phenomenological theory and Moriya's microscopic theory, applicability of our mechanism, and the similarities and differences between our case and the strong-$LS$-coupling case.

A unified composite model of inflation and dark matter in the Nambu-Jona-Lasinio theory

description: In this work, we propose a cosmological scenario inherently based on the effective Nambu-Jona-Lasinio (NJL) model that cosmic inflation and dark matter can be successfully described by a single framework. On the one hand, the scalar channel of the NJL model plays a role of the composite inflaton (CI) and we show that it is viable to achieve successful inflation via a non-minimal coupling to gravity. For model of inflation, we compute the inflationary parameters and confront them with recent Planck 2015 data. We discover that the predictions of the model are in excellent agreement with the Planck analysis. We also present in our model a simple connection of physics from the high scales to low scales via renormalization group equations of the physical parameters. On the other hand, the pseudoscalar channel can be assigned as a candidate for composite dark matter (CD). For model of dark matter, we couple the pseudoscalar to the Higgs sector of the standard model with the coupling strength $κ$ and estimate its thermally-averaged relic abundance. We discover that the CD mass is strongly sensitive to the coupling $κ$. We find in case of light CD, $M_{s} M_{W,\,Z}$ (or $>M_{h}$), the required relic abundance can be satisfied for value of the CD mass $M_{s}\sim 410\,{\rm GeV}$ for $κ= 0.5$. In contradiction to the light mass case, however, the CD mass in this case can even be heavier when the coupling is getting larger.

The Effects Of Celebrity Endorsement In Advertisement On Consumer Buying Preference (In The Case Of Anbessa Shoes)
Creators: name: Cheru, Tadesse
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: The purpose of this study is to examine the effectiveness of celebrity endorsement advertisements on consumer buying preference in the case of Anbessa Shoes. Trustworthiness, physical attractiveness, expertise and celebrity product match-up have been examined as the potential factors that affected consumer buying preference to use the product of Anbessa Shoe. Structured questionnaires were developed. The hypotheses were simultaneously tested on a sample of 338 customers out of 385 distributed, giving a valid response rate of 88 percent. Several analytical techniques were used to assess the relationships among the variables under investigation such as correlation assumption tests like multicollinearity and normality tests, and multiple linear regressions, analysis The results showed that, perceived physical attractiveness, expertise of the celebrity and perceived celebrity product congruence/match-up have a positive influence on consumer buying preference. However, trustworthiness of the celebrity has not been found having a significant influence on the consumer buying preference in the case of Anbesssa Shoe consumers. Celebrity endorsements (measured by the attributes of physical attractiveness, expertise, and product/celebrity match) have a significant positive influence on the consumers buying preference. The implication is that marketers in the industry should consider the use of celebrities in their promotional endeavors so as to grab consumers" attention for their advertisements
Metric Algebroid and Poisson-Lie T-duality in DFT

description: In this article we investigate the gauge invariance and duality properties of DFT based on a metric algebroid formulation given previously in [1]. The derivation of the general action given in this paper does not employ the section condition. Instead, the action is determined by requiring a pre-Bianchi identity on the structure functions of the metric algebroid and also for the dilaton flux. The pre-Bianchi identity is also a sufficient condition for a generalized Lichnerowicz formula to hold. The reduction to the D-dimensional space is achieved by a dimensional reduction of the fluctuations. The result contains the theory on the group manifold, or the theory extending to the GSE, depending on the chosen background. As an explicit example we apply our formulation to the Poisson-Lie T-duality in the effective theory on a group manifold. It is formulated as a 2D-dimensional diffeomorphism including the fluctuations.

description: We consider effective Higgs boson couplings, including both the CP-even and CP-odd couplings, that affect Higgs boson pair production in this study. Through the partial wave analysis, we find that the process $gg\to hh$ is dominated by the $s$-wave component even at a 100~TeV $pp$-collider. Making use of the $s$-wave kinematics, we propose a cut efficiency function to mimic the collider simulation and obtain the potential of measuring Higgs effective couplings at the 14~TeV LHC with an integrated luminosity of $3000~{\rm fb}^{-1}$ and at a 100 TeV $pp$-collider. Analytical expressions of the $2σ$ exclusion limits at the LHC and the $5σ$ discovery bands at the 100 TeV machine are given.

description: Electron transport through a nanoscale system is an inherently stochastic quantum mechanical process. Electric current is a time series of electron tunnelling events separated by random intervals. Thermal and quantum noise are two sources of this randomness. In this paper, we used the quantum master equation to consider the following questions: (i) Given that an electron has tunnelled into the electronically unoccupied system from the source electrode at some particular time, how long is it until an electron tunnels out to the drain electrode to leave the system electronically unoccupied, where there were no intermediate tunnelling events ("the" tunnelling path)? (ii) Given that an electron has tunnelled into the unoccupied system from the source electrode at some particular time, how long is it until an electron tunnels out to the drain electrode to leave the system electronically unoccupied, where there were no intermediate tunnelling events ("an" tunnelling path)? (iii) What are the distributions of these times? We show that electron correlations suppress the difference between "the" and "an" electron tunnelling paths.

Estimation of optimal hedge ratio for oil futures: an application to the Ethiopian petroleum supply enterprise
Creators: name: Tesfaye, Belete
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: Ethiopian Petroleum Supply Enterprise, the sole importer of different oil products in Ethiopia is exposed to price fluctuation risk. Hedging oil with futures contract can offset this risk. So, the most important issue is to what extent or percentage the risk exposure should be hedged with futures contract. The aim of this thesis is to estimate an optimal hedge ratio that will provide the highest price risk reduction using monthly spot and futures price from October, 1990 to March ,2019. Hedge ratios and hedging effectiveness are determined by employing three models namely: Naïve, OLS (Ordinary Least Square) and ECM (Error Correction Model). Hedging effectiveness is evaluated and compared for the three models. The empirical results show that the ECM model provide highest variance(risk) reduction as compared to other models indicating that this model fits better in designing hedging strategy for EPSE. The empirical finding suggests that the EPSE can use oil futures contract as an effective instrument to minimize price fluctuation risk.

We prove pointwise estimates of eigenfunctions corresponding to negative eigenvalues and upper finite-time horizon estimates for heat kernels. We also analyze the relation between the matching lower estimates of the heat kernel and the ground state near the origin. Our results cover the relativistic Schrödinger operator with Coulomb potential.

description: The interpretation of dark matter direct detection experiments is complicated by the fact that neither the astrophysical distribution of dark matter nor the properties of its particle physics interactions with nuclei are known in detail. To address both of these issues in a very general way we develop a new framework that combines the full formalism of non-relativistic effective interactions with state-of-the-art halo-independent methods. This approach makes it possible to analyse direct detection experiments for arbitrary dark matter interactions and quantify the goodness-of-fit independent of astrophysical uncertainties. We employ this method in order to demonstrate that the degeneracy between astrophysical uncertainties and particle physics unknowns is not complete. Certain models can be distinguished in a halo-independent way using a single ton-scale experiment based on liquid xenon, while other models are indistinguishable with a single experiment but can be separated using combined information from several target elements.

description: A polynomial lemniscate is a curve in the complex plane defined by $\{z \in \mathbb{C}:|p(z)|=t\}$. Erdös, Herzog, and Piranian posed the extremal problem of determining the maximum length of a lemniscate $Λ=\{ z \in \mathbb{C}:|p(z)|=1\}$ when $p$ is a monic polynomial of degree $n$. In this paper, we study the length and topology of a random lemniscate whose defining polynomial has independent Gaussian coefficients. In the special case of the Kac ensemble we show that the length approaches a nonzero constant as $n \rightarrow \infty$. We also show that the average number of connected components is asymptotically $n$, and we observe a positive probability (independent of $n$) of a giant component occurring.

description: The Phase Retrieval problem is dealt with for the challenging case where just a single set of (phaseless) radiated field data is available. In particular, even still emulating the solution of crosswords puzzles, we provide decisive improvements over our recent approaches. In fact, by exploiting bandlimitedness and a suitable set of intersecting curves, we definitively lower the computational complexity (thus eliminating drawbacks) of our previous techniques. Numerical examples, concerning applications of actual interest, support the given theory and confirm the effectiveness of the developed procedure.

description: Pressure ulcers/injuries management continues to be a challenge in different care settings (Dealey et al., 2015; Sardo et al., 2018, 2023) and represents an important health care quality indicator (Kottner et al., 2018; McEvoy et al., 2021; Padula & Delarmente, 2019; Silva et al., 2013; Soares & Heidemann, 2018). Although there is no evidence that the use of pressure ulcer risk assessment scales reduce the incidence of pressure ulcers by itself (Moore & Patton, 2019) the systematic use of pressure ulcer risk assessment scales allows the early identification of patients “at risk” and their specific risk factors (Braden, 2012; Sardo et al., 2015, 2018). International guidelines (EPUAP et al., 2019) recommends that the pressure ulcer risk assessment should be performed (using a validated tool) as soon as possible and periodically reassessed. Besides, a comprehensive skin and tissue assessment should be performed in all health care settings and should include techniques to identify blanching response, temperature changes, oedema, and changes in tissue consistency in relation to surrounding tissue (EPUAP et al., 2019). Furthermore, the skin under and around medical devices should also be inspected at least twice daily for the signs of pressure-related injury on the surrounding tissue (EPUAP et al., 2019). Being admitted to a hospital is an important measure of frailty (Sardo, Simões, Alvarelhão, Simões, & Melo, 2016) and nursing team should manage several pressure ulcer risk factors (Sardo, Simões, Alvarelhão, Simões, Machado, et al., 2016) in different care settings, namely in emergency services. A recent systematic review (Sardo et al., 2023) concluded that the prevalence of pressure ulcers/injuries in emergency services ranges from 5.2% (at admission) to 12.3% (at discharge) and the incidence of pressure ulcers/injuries in emergency services ranges from 4.5% to 78.4%. Thus, pressure ulcer/injury prevention protocols (that comprise early nursing care/interventions) should be implemented as soon as possible (Denby & Rowlands, 2010; EPUAP et al., 2019). So, the management of pressure ulcers/injuries (risk) in hospital emergency services is a real and current problem/challenge, and nursing team should implement preventive measures based on the best available evidence (Alshahrani et al., 2021; Marques et al., 2023). Thus, the main objective of this scoping review is to map the available evidence of nursing care provided to prevent the development of pressure ulcers/injuries in emergency services.
$\boldsymbol{μ^-}$- $\boldsymbol{e^+}$ conversion in upcoming LFV experiments

description: We present an illustrative discussion of the physics potential of $μ^-$- $e^+$ conversion. We point out that this process, although much less frequently studied than the related but much more popular processes of $μ^-$- $e^-$ conversion and neutrinoless double beta decay, in fact is a promising alternative possibility to detect both lepton flavour and number violation. However, for this goal to be reached, a combined effort of experiments and theory, both in nuclear and particle physics, is necessary to advance. The aim of this paper is to be an "appetiser" to trigger such an initiative.

Intermediate-scale statistics for real-valued lacunary sequences

description: We study intermediate-scale statistics for the fractional parts of the sequence $(αa_n)_{n=1}^{\infty}$, where $(a_n)_{n=1}^{\infty}$ is a positive, real-valued lacunary sequence, and $α\in\mathbb{R}$. In particular, we consider the number of elements $S_{N}(L,α)$ in a random interval of length $L/N$, where $L=O\left(N^{1-ε}\right)$, and show that its variance (the number variance) is asymptotic to $L$ with high probability w.r.t. $α$, which is in agreement with the statistics of uniform i.i.d. random points in the unit interval. In addition, we show that the same asymptotics holds almost surely in $α\in\mathbb{R}$ when $L=O\left(N^{1/2-ε}\right)$. For slowly growing $L$, we further prove a central limit theorem for $S_{N}(L,α)$ which holds for almost all $α\in\mathbb{R}$.

description: Analyzing the dimension of an unknown quantum system in a device-independent manner, i.e., using only the measurement statistics, is a fundamental task in quantum physics and quantum information theory. In this paper, we consider this problem in the prepare-and-measure scenario. Specifically, we provide a lower bound on the dimension of the prepared quantum systems which is a function that only depends on the measurement statistics. Furthermore, we show that our bound performs well on several examples. {In particular}, we show that our bound provides new insights into the notion of dimension witness, and we also use it to show that the sets of restricted-dimensional prepare-and-measure correlations are not always convex.

Quantitative prediction of sling events in turbulence at high Reynolds numbers

description: Collisional growth of droplets, such as occurring in warm clouds, is known to be significantly enhanced by turbulence. Whether particles collide depends on their flow history, in particular on their encounters with highly intermittent small-scale turbulent structures, which despite their rarity can dominate the overall collision rate. Intuitively, strong vortices may act as slings for inertial particles, leading to intersections where several streams of particles collide at large velocities. Here, we develop a quantitative criterion for sling events based on the velocity gradient history along particle paths. We demonstrate by combination of theory and simulations that the problem reduces to a one-dimensional localization problem as encountered in condensed matter physics. The reduction demonstrates that the creation of slings is completely controlled by the smallest negative eigenvalue of the velocity gradient tensor. We use fully resolved turbulence simulations to confirm our predictions and study their Stokes and Reynolds number dependence. We also discuss extrapolations to the parameter range relevant in clouds, showing that sling events at high Reynolds numbers are significantly enhanced for small Stokes numbers.
