description: Non-gravitational feedback affects the nature of the intra-cluster medium (ICM). X-ray cooling of the ICM and in situ energy feedback from AGN's and SNe as well as {\it preheating} of the gas at epochs preceding the formation of clusters are proposed mechanisms for such feedback. While cooling and AGN feedbacks are dominant in cluster cores, the signatures of a preheated ICM are expected to be present even at large radii. To estimate the degree of preheating, with minimum confusion from AGN feedback/cooling, we study the excess entropy and non-gravitational energy profiles upto $r_{200}$ for a sample of 17 galaxy clusters using joint data sets of {\it Planck} SZ pressure and {\it ROSAT/PSPC} gas density profiles. The canonical value of preheating entropy floor of $\gtrsim 300$ keV cm$^2$, needed in order to match cluster scalings, is ruled out at $\approx 3σ$. We also show that the feedback energy of 1 keV/particle is ruled out at 5.2$σ$ beyond $r_{500}$. Our analysis takes both non-thermal pressure and clumping into account which can be important in outer regions. Our results based on the direct probe of the ICM in the outermost regions do not support any significant preheating.

description: We present several classes of constraints on the discontinuities of Feynman integrals that go beyond the Steinmann relations. These constraints follow from a geometric formulation of the Landau equations that was advocated by Pham, in which the singularities of Feynman integrals correspond to critical points of maps between on-shell spaces. To establish our results, we review elements of Picard-Lefschetz theory, which connect the homotopy properties of the space of complexified external momenta to the homology of the combined space of on-shell internal and external momenta. An important concept that emerges from this analysis is the question of whether or not a pair of Landau singularities is compatible-namely, whether or not the Landau equations for the two singularities can be satisfied simultaneously. Under conditions we describe, sequential discontinuities with respect to non-compatible Landau singularities must vanish. Although we only rigorously prove results for Feynman integrals with generic masses in this paper, we expect the geometric and algebraic insights that we gain will also assist in the analysis of more general Feynman integrals.

Corporate Governance Policy and Its Effects on the Performance of Private Banks in Ethiopia - A Comparative Analysis
Creators: name: Tesemma, Yohannes
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: It is apparent that nowadays the issue of corporate governance has got due attention from various stakeholders such as the general public, academia and government policy makers. This may be due to the recognition of either the multifaceted benefits derived from its effective implementation or the severe consequences it poses otherwise. For this reason the objective of this research is to analyze the effects of the corporate governance policy enforced by the NBE on the performance of the private commercial banks operating in Ethiopia. Thus both primary and secondary data are collected from 14 (fourteen) private banks operating in the country and in order to address the objectives of the study, a deductive research approach and various statistical techniques such as Descriptive Statistics, T- test, Spearman's Rank Correlation and Analysis of Variance (ANOVA) were employed so as to make comparative analyses among the corporate governance and performance variables during the periods 2011-15 and 2016 respectively. Taking in to account the expected outcome of implementing the policy effectively and the empirical findings of previously done researches, this study has made five hypotheses asserting that the corporate governance variables could have significant effects on bank performance. The analyses result from descriptive statistics depicts the existence of improvements in the implementation of most of the requirements of the policy relatively. However, analytical results from t-tests show that the changes were significant for some variables, but not for others. Spearman's correlation results also demonstrate the existence of low correlation in general, except for board size and board composition in 2011-15. The results obtained using ANOVA on the other hand show that the mean variance of all corporate governance variables and bank performance are found not-significant during the study periods. Hence, all the hypotheses, except related to Board size, were supported. Based on the results obtained from the analyses some recommendations such as the determination of optimal board size by the banks , enhancing board composition through the participation of executives and/or non-executive professional personnel in boards' and others are made that are thought to enhance the effectiveness of the policy through safekeeping the interests of both shareholders and other stakeholders and hence improving the performances of the banks accordingly; for that the proactive engagements of all the concerned such as the supervisory organ, the respective banks and others will have a remarkable impact on the effectiveness of the policy under consideration. Key words: Corporate Governance, Corporate Governance Policy, Bank Performance, Board Structure.

description: Vorgestellt wird eine theoretische Auseinandersetzung mit den Entstehungsbedingungen von Begeisterung in der Erwerbsarbeit. Begeisterung wird als spezielle Wohlbefindens-Emotion definiert und gegen Zustände wie Freude und Flow abgegrenzt. Begeisterung als emotionaler Ausdruck für persönliches Sinnerleben und Selbstverwirklichung entsteht, so die Hauptthese, wenn eine Person in der (Arbeits-)Tätigkeit die Realisierung zentraler eigener Ziele und Motive erlebt. Handlungsspielraum, Neuartigkeit der Aufgabe, Ergebnisfeedback und ein mittlerer bis hoher Schwierigkeitsgrad sind notwendige aber nicht hinreichenden Arbeitsbedingungen für die Entstehung von Begeisterung. Auf Seiten der Person sind darüber hinaus eine komplexe Motivstruktur, Bewusstheit, Kompetenzen, die Fähigkeit zur stabil-flexiblen Handlungsregulation und eine seelisch-körperliche Leistungsfähigkeit erforderlich, damit sich Begeisterung einstellen kann. Die zentralen theoretischen Annahmen wurden in einer ersten empirischen Überprüfung mittels problemzentrierter Interviews weitgehend bestätigt.

description: We present predictions for the photon energy spectrum in inclusive $B\to X_sγ$ decays mediated by the electromagnetic penguin operator $O_7$ to N$^3$LL$'$. We use soft-collinear effective theory (SCET) to resum the singular contributions in the peak region at large photon energy. In the tail region the resummed predictions are matched to fixed order at N$^3$LO, where we include the known fixed-order contributions for $O_7$ up to $\mathcal{O}(α_s^2)$. We develop a method to suitably parametrize the still unknown $\mathcal{O}(α_s^3)$ nonsingular corrections in terms of theory nuisance parameters, whose variations provide an estimate of the associated theory uncertainty. In this context, we also study different ways to treat higher-order cross terms in the matching. Another important aspect of our analysis is the short-distance scheme used for the $b$-quark mass $m_b$. We find that in the present context, the 1$S$ mass scheme, which was previously used up to 2-loop order, fails to work at 3-loop order, because the mass scheme enters at a soft scale much smaller than $m_b$ here, for which the 1$S$ scheme was not devised. Using instead the MSR mass scheme with $R\sim 1\,\mathrm{GeV}$, we obtain stable results with good perturbative convergence up to N$^3$LL$'$.

description: ABSTRACT: Lignin-derived porous carbons have great potential for energy storage applications. However, their traditional synthesis requires highly corrosive activating agents in order to produce porous structures. In this work, an environmentally friendly and unique method has been developed for preparing lignin-based 3D spherical porous carbons (LSPCs). Dropwise injection of a lignin solution containing PVA sacrificial templates into liquid nitrogen produces tiny spheres that are lyophilized and carbonized to produce LSPCs. Most of the synthesized samples possess excellent specific surface areas (426.6−790.5 m2 /g) along with hierarchical micro- and mesoporous morphologies. When tested in supercapacitor applications, LSPC-28 demonstrates a superior specific capacitance of 102.3 F/g at 0.5 A/g, excellent rate capability with 70.3% capacitance retention at 20 A/g, and a commendable energy density of 2.1 Wh/kg at 250 W/kg. These materials (LSPC-46) also show promising performance as an anode material in sodium-ion batteries with high reversible capacity (110 mAh g−1 at 100 mA g−1 ), high Coulombic efficiency, and excellent cycling stability. This novel and green technique is anticipated to facilitate the scalability of lignin-based porous carbons and open a range of research opportunities for energy storage applications

Year: 2018

description: The objective of this study was to examine the determinants of export performance of textile and garment companies in Ethiopia with regard to export market knowledge, management competence, technology, product quality, infrastructure and policy and regulation. A quantitative research design and explanatory research approaches were used. Primary data sources through questionnaire were used. Statistical Package for the Social Sciences (SPSS) version 20 was used to analyze the data. The study had 81.6% response rate. To achieve the objectives a conceptual model was formulated by reviewing previous related literatures, hypotheses were developed and tested. The variation explained by the regression of all the predictor variables on export performance was 96.4%. It can be said that there is a relatively good fit between the model and data. Correlation between the independent and dependent variables indicates a degree of less multi-collinearity. According to the findings, management competence, export market knowledge, technology, policy and regulation and product quality have positive and significant effect on export performance. Even though infrastructure also has positive relation on export performance, its effect was not statistically significant. Export performance was mainly influenced by management competence followed by export market knowledge, technology, policy and regulation, and product quality. Infrastructure did not show a statistically significant effect. Therefore, textile and garment export companies could benefit from considering management competence as main targets for their better export performance, they could also benefit from scaling up the knowledge of employees with regard to export market, and equipped with state-of-the-art technologies, relaxed policy and regulation and product quality to have competitive advantages and manage needs of their customers in the international market

description: The least concave majorant, $\hat F$, of a continuous function $F$ on a closed interval, $I$, is defined by \[ \hat F (x) = \inf \left\{ G(x): G \geq F, G \mbox{ concave}\right\},\; x \in I. \] We present here an algorithm, in the spirit of the Jarvis March, to approximate the least concave majorant of a differentiable piecewise polynomial function of degree at most three on $I$. Given any function $F \in \mathcal{C}^4(I)$, it can be well-approximated on $I$ by a clamped cubic spline $S$. We show that $\hat S$ is then a good approximation to $\hat F$. We give two examples, one to illustrate, the other to apply our algorithm.
Creating Interactive Plots to Display Weather Data Using the Holoviz/Geoviews Libraries in Python

Publisher: name: Zenodo

description: Using interactive maps to display and analyze meteorological data is crucial for understanding weather patterns and making informed decisions. It is an avenue that generally, has been seldom explored or made widely available. Interactive maps allow users to visualize and explore data in a more engaging and interactive way, providing a better understanding of the spatial distribution of meteorological phenomena. These maps can display real-time weather data, such as temperature, precipitation, wind direction and speed, air pressure, and other important metrics. Additionally, interactive maps can incorporate various layers of information that can provide a more comprehensive view of data. Overall, the use of interactive maps for meteorological data analysis is a valuable tool for researchers, forecasters, and the general public to better understand and prepare for weather events. Using Python and the powerful Geoviews, Datashader, Panel and Bokeh libraries, I have developed interactive maps that display various meteorological variables across the United States. The maps I created plot ASOS reports, which provide information on precipitation type (including MPING), wind gusts, precipitation, and temperature. The interactive maps I developed offer an engaging and interactive way to visualize and explore this data. One of the significant advantages of the interactivity allowed with these libraries is it allows users to go back to each hour over the last day. I utilized the Datashader library to be able to add gridded numerical model data into Geoviews as well. This allows users to be able to zoom into only areas that they’re interested in when looking at a modeled forecast. I also developed an ERA-5 reanalysis viewer, which allows users to select any date in the ERA dataset and display any variable for that day. Overall, the maps and tools I developed using Python, Geoviews, Datashader, Panel and Bokeh libraries provide a powerful and flexible platform for analyzing meteorological data. They offer an engaging and interactive way to explore meteorological variables and can be used by researchers, forecasters, and anyone interested in weather to analyze and interpret past and future data in a more meaningful way.
The semi-inclusive jet function in SCET and small radius resummation for inclusive jet production

description: We introduce a new kind of jet function: the semi-inclusive jet function $J_i(z, ω_J, μ)$, which describes how a parton $i$ is transformed into a jet with a jet radius $R$ and energy fraction $z = ω_J/ω$, with $ω_J$ and $ω$ being the large light-cone momentum component of the jet and the corresponding parton $i$ that initiates the jet, respectively. Within the framework of Soft Collinear Effective Theory (SCET) we calculate both $J_q(z, ω_J, μ)$ and $J_g(z, ω_J, μ)$ to the next-to-leading order (NLO) for cone and anti-k$_{\rm T}$ algorithms. We demonstrate that the renormalization group (RG) equations for $J_i(z, ω_J, μ)$ follow exactly the usual DGLAP evolution, which can be used to perform the $\ln R$ resummation for {\it inclusive} jet cross sections with a small jet radius $R$. We clarify the difference between our RG equations for $J_i(z, ω_J, μ)$ and those for the so-called unmeasured jet functions $J_i(ω_J, μ)$, widely used in SCET for {\it exclusive} jet production. Finally, we present applications of the new semi-inclusive jet functions to inclusive jet production in $e^+e^-$ and $pp$ collisions. We demonstrate that single inclusive jet production in these collisions shares the same short-distance hard functions as single inclusive hadron production, with only the fragmentation functions $D_i^h(z, μ)$ replaced by $J_i(z, ω_J, μ)$. This can facilitate more efficient higher-order analytical computations of jet cross sections. We further match our $\ln R$ resummation at both LL$_{R}$ and NLL$_{R}$ to fixed NLO results and present the phenomenological implications for single inclusive jet production at the LHC.

Factors Affecting Consumers' Purchase Decision of Over-The-Counter (OTC) Medicines: Empirical Evidences from Community Pharmacies in Ethiopia.
Creators: name: Wube, Meseret
Publisher: name: National Academic Digital Repository of Ethiopia

description: The objective of this study was to examine factors affecting consumers' purchase decision of over-the-counter (OTC) medicines from community pharmacies in Ethiopia. A quantitative research design, and descriptive and explanatory research approaches were used. Both primary and secondary data were collected. For primary data (questionnaire) and secondary data (related literatures and different documents) were used. Statistical Package for the Social Sciences (SPSS) version 23 was used to analyze the data. The study had a 96% response rate. According to the finding, pharmacist's recommendation, price, and country of origin of OTC medicines have positive and significant effect on consumers' purchase decision. Even though, past experience and families' and friends' recommendation also have positive effect on consumers' purchase decision of OTC medicine, their effect were not statistically significant. Consumers' decisions to purchase OTC medicines were influenced by pharmacist's recommendation followed by price and country of origin of OTC medicines. Past experience and families' and friends' recommendation did not show a statistically significant effect. Therefore; marketers of OTC medication could benefit from considering community pharmacists as main targets for their promotional activities, they could also benefit from pricing strategies to have competitive advantages and manage needs of their consumers, and marketers could also capitalize on the country of origin for their products in their marketing activities.

description: Flavor symmetries à la Froggatt-Nielsen~(FN) provide a compelling way to explain the hierarchies of fermionic masses and mixing angles in the Yukawa sector. In Supersymmetric~(SUSY) extensions of the Standard Model where the mediation of SUSY breaking occurs at scales larger than the breaking of flavor, this symmetry must be respected not only by the Yukawas of the superpotential, but by the soft-breaking masses and trilinear terms as well. In this work we show that contrary to naive expectations, even starting with completely flavor blind soft-breaking in the full theory at high scales, the low-energy sfermion mass matrices and trilinear terms of the effective theory, obtained upon integrating out the heavy mediator fields, are strongly non-universal. We explore the phenomenology of these SUSY flavor models after the latest LHC searches for new physics.

description: This letter investigates low frequency 1/ f noise in hBN encapsulated graphene device in a dual gated geometry. The noise study is performed as a function of top gate carrier density (nT G) at different back gate densities (nBG). The noise at low nBG is found to be independent of top gate carrier density. With increasing nBG, noise value increases and a noise peak is observed near charge inhomogeneity of the device. Further increase in nBG leads to decrease in noise magnitude. The shape of the noise is found to be closely related to charge inhomogeneity region of the device. Moreover, the noise and conductivity data near charge neutrality shows clear evidence of noise emanating from combination of charge number and mobility fluctuation

description: Abstract Objectives: Osteoporosis because of physical inactivity is one of the major complications associated with neuromuscular disorders. The study aimed to compare using Suit therapy and whole-body vibration in addition to selected physical therapy program to improve Bone Mineral Density in children with cerebral palsy of spastic diplegia. Methods: Forty-six patients were classified randomly into two equal groups. Patients in the group (A) engaged in a selected physical therapy program, also besides, suit therapy training program while those in the group (B) received the same selected physical therapy program received by group (A) in addition to the whole-body vibration training program. The treatment programs were conducted three times per week for twelve successive weeks. Measurements obtained included bone mineral density at the lumbar spine as well as at the femoral neck. These measures were recorded pre- and post-treatment. Results: There was a significant improvement in favor of the whole-body Vibration group. Bone mineral density improved significantly at both the lumbar spine (P=.038) and the femoral neck (P=.005) in the WBV group as compared to the Suit therapy group. Conclusions: Whole-body vibration is effective in improving Bone Mineral Density rather than Suit therapy in children with cerebral palsy of spastic diplegia.

description: In the cosmic web, galaxy superclusters or their high-density cores are the largest objects that may collapse at present or during the future evolution. We study the dynamical state and possible future evolution of galaxy superclusters from the Sloan Great Wall (SGW), the richest galaxy system in the nearby Universe. We calculated supercluster masses using dynamical masses of galaxy groups and stellar masses of galaxies. We employed normal mixture modelling to study the structure of rich SGW superclusters and search for components (cores) in superclusters. We analysed the radial mass distribution in the high-density cores of superclusters centred approximately at rich clusters and used the spherical collapse model to study their dynamical state. We found that the lower limit of the total mass of the SGW is approximately $M = 2.5\times~10^{16}h^{-1}M_\odot$. Different mass estimators of superclusters agree well, the main uncertainties in masses of superclusters come from missing groups and clusters. We detected three high-density cores in the richest SGW supercluster (SCl~027) and two in the second richest supercluster (SCl~019). They have masses of $1.2 - 5.9 \times~10^{15}h^{-1}M_\odot$ and sizes of up to $\approx 60 h^{-1}$ Mpc. The high-density cores of superclusters are very elongated, flattened perpendicularly to the line of sight. The comparison of the radial mass distribution in the high-density cores with the predictions of spherical collapse model suggests that their central regions with radii smaller than $8 h^{-1}$Mpc and masses of up to $M = 2\times~10^{15}h^{-1}M_\odot$ may be collapsing. The rich SGW superclusters with their high-density cores represent dynamically evolving environments for studies of the properties of galaxies and galaxy systems.

description: By first-principles calculations, we study the magnetic and topological properties of XYBi2Te5-family (X, Y = Mn, Ni, V, Eu) compounds. The strongly coupled double magnetic atom-layers can significantly enhance the magnetic ordering temperature while keeping the topologically nontrivial properties. Particularly, NiVBi2Te5 is found to be a magnetic Weyl semimetal in bulk and a Chern insulator in thin film with both the Curie temperature (~150 K) and full gap well above 77 K. Ni2Bi2Te5, MnNiBi2Te5, NiVBi2Te5 and NiEuBi2Te5 exhibits intrinsic dynamic axion state. Among them, MnNiBi2Te5 has a Neel temperature over 200 K and Ni2Bi2Te5 even demonstrates antiferromagnetic order above room temperature. These results indicate an approach to realize high temperature quantum anomalous Hall effect and other topological quantum effects for practical applications.

description: We study the effect of a local potential shift induced by a side electrode on the edge modes at the boundary between gapped and ungapped bilayer graphene. A potential shift close to the gapped-ungapped boundary causes the emergence of unprotected edge modes, propagating in both directions along the boundary. These counterpropagating edge modes allow edge backscattering, as opposed to the case of valley-momentum-locked edge modes. We then calculate the conductance of a bilayer graphene wire in presence of finger-gate electrodes, finding strong asymmetries with energy inversion and deviations from conductance quantization that can be understood with the gate-induced unprotected edge modes.

description: In this paper we aim to derive solutions for the SU($\mathcal{N}$) self-dual Yang-Mills (SDYM) equation with arbitrary $\mathcal{N}$. A set of noncommutative relations are introduced to construct a matrix equation that can be reduced to the SDYM equation. It is shown that these relations can be generated from two different Sylvester equations, which correspond to the two Cauchy matrix schemes for the (matrix) Kadomtsev-Petviashvili hierarchy and the (matrix) Ablowitz-Kaup-Newell-Segur hierarchy, respectively. In each Cauchy matrix scheme we investigate the possible reductions that can lead to the SU$(\mathcal{N})$ SDYM equation and also analyze the physical significance of some solutions, i.e. being Hermitian, positive-definite and of determinant being one.

description: We develop a general method for the self consistent calculation of the hydrodynamics of an astrophysical object irradiated by a radiation field with an arbitrary strength and spectral energy distribution (SED). Using the XSTAR photoionization code, we calculate heating and cooling rates as a function of gas photoionization parameter and temperature for several examples of SEDs: bremsstrahlung, blackbody, hard and soft state XRBs, Type 1 and Type 2 AGN. As an application of our method we study the hydrodynamics of 1-dimensional spherical winds heated by a uniform radiation field using the code Athena++. We find that in all cases explored a wind settles into a transonic, steady state. The wind evolves along the radiative heating equilibrium curve until adiabatic cooling effects become important and the flow departs from radiative equilibrium. If the flow is heated very rapidly, for example as in a thermally unstable regime, the corresponding column density of gas is low. Perhaps one of the most intriguing results of our work is the two stage acceleration of the wind that happens when there are two thermally unstable regions and the flux is relatively high. The efficiency with which the radiation field transfers energy to the wind is dependent on the SED of the external source, particularly the relative flux of soft X-rays. These results suggest that detailed photoionization calculations are essential not only to predict spectra but also to properly capture the flow dynamics.

Searching beyond pixels and tiles

description: When confronted with a large amount of data, an immediate question is that of search. For traditional database systems this often means how to effectively retrieve a single entry such as a business transaction or a sensor measurement. In this case, queries are accelerated by building suitable indices that index individual entries. For geospatial data, the single entry—a pixel—is often not of that much interest. Rather, a user might want to find groups of pixels that define a storm, a heat wave, an atmospheric river, or a set of clouds obscuring a satellite image. With this in mind, we introduce the concept of overview indices. These are regional indices that summarize statistics across groups of pixels. They go beyond tile-level metadata often found in STAC-like catalogues by allowing us to identify relevant subsets of the data without loading the pixel-level raw data. Our talk will discuss the design of these indices—based on geoparquet—as well as their various uses. The latter will extend to questions of data federation and query optimization where minimizing (data transfer) costs is needed for cross-data center and cross-region operations.

description: A remarkable prediction of the Standard Model is that, in the absence of corrections lifting the energy density, the Higgs potential becomes negative at large field values. If the Higgs field samples this part of the potential during inflation, the negative energy density may locally destabilize the spacetime. We use numerical simulations of the Einstein equations to study the evolution of inflation-induced Higgs fluctuations as they grow towards the true (negative-energy) minimum. These simulations show that forming a single patch of true vacuum in our past light cone during inflation is incompatible with the existence of our Universe; the boundary of the true vacuum region grows outward in a causally disconnected manner from the crunching interior, which forms a black hole. We also find that these black hole horizons may be arbitrarily elongated---even forming black strings---in violation of the hoop conjecture. By extending the numerical solution of the Fokker-Planck equation to the exponentially suppressed tails of the field distribution at large field values, we derive a rigorous correlation between a future measurement of the tensor-to-scalar ratio and the scale at which the Higgs potential must receive stabilizing corrections in order for the Universe to have survived inflation until today.

description: We consider estimation of the quadratic (co)variation of a semimartingale from discrete observations which are irregularly spaced under high-frequency asymptotics. In the univariate setting, results from Jacod (2008) are generalized to the case of irregular observations. In the two-dimensional setup under non-synchronous observations, we derive a stable central limit theorem for the estimator by Hayashi and Yoshida (2005) in the presence of jumps. We reveal how idiosyncratic and simultaneous jumps affect the asymptotic distribution. Observation times generated by Poisson processes are explicitly discussed.

description: The aim of this study was to assess attitude of pharmacists towards generic medications. The study was conducted in all government hospitals pharmacies in Addis Ababa city, from April 30, 2019-May 30, 2019. Mixed (quantitative and qualitative) research approach was used; the data collection tools were self-administered questionnaire and interviews. The frequency and percentage were used for demographic data presentation. The results were analyzed using Cronbach Alpha coefficients to measure reliability of the research instrument, t-test and one-way ANOVA to test the hypothesis and the variance between groups; and Spearman.s rho to determine the correlation and relationship between two variables of interest. Regression was also used to test the relationship between attitude, subjective norms, perceived behavioral control and behavioral intention. According to this study the pharmacists. attitude (positive or negative) towards generics medicine does not depend on qualifications, years of experience and age. Regarding gender, the study found that there is a significant difference between male and female for the pharmacists. attitude (positive or negative) towards generics medicine. There was a weak positive correlation between attitude and subjective norms, which was statistically significant, rs =0.217, p =0.005. And, there was a strong positive correlation between attitude and perceived behavioral control, which was statistically significant, rs =0.524, p = 0.000. There is statistically a significant relationship between attitude and behavioral intention (positive correlation). The study concluded that attitude is one of the most important personal factors influencing both the organization and individual consumer buying behavior

description: Trap-assisted nonradiative recombination is known to limit the efficiency of optoelectronic devices, but the conventional multi-phonon emission (MPE) process fails to explain the observed loss in wide-band-gap materials. Here we highlight the role of trap-assisted Auger-Meitner (TAAM) recombination, and present a first-principles methodology to determine TAAM rates due to defects or impurities in semiconductors or insulators. We assess the impact on efficiency of light emitters in a recombination cycle that may include both TAAM and carrier capture via MPE. We apply the formalism to the technologically relevant case study of a calcium impurity in InGaN, where a Shockley-Read-Hall recombination cycle involving MPE alone cannot explain the experimentally observed nonradiative loss. We find that, for band gaps larger than 2.5 eV, the inclusion of TAAM results in recombination rates that are orders of magnitude larger than recombination rates based on MPE alone, demonstrating that TAAM can be a dominant nonradiative process in wide-band-gap materials. Our computational formalism is general and can be applied to the calculation of TAAM rates in any semiconducting or insulating material.
