Impacts of Trade Liberalization on Growth and Poverty in Ethiopia: A Dynamic Computable General Equilibrium Model
Creators: name: Mohammed, Seid
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2007

description: This paper presents a dynamic Computable General Equilibrium (CGE) Model for Ethiopia's trade liberalization that allows for quantification of income and welfare effects stemming from tariff reduction. This dynamic model has been built using a Social Accounting Matrix (SAM) of 1999/2000 for Ethiopia. The model is simulated for alternative policies scenarios depicting full and indiscriminating liberalization, full and discriminating liberalization, gradual and rationalized liberalization and instantaneous tariff liberalization. The main findings of these scenarios are a decline in poverty among all households in the long run. In the short run, poverty remains significantly unaffected for most of the simulations' Scenarios. The simulations' results show that static version of the model underestimates trade liberalization's impacts on production, and welfare, since it excludes the accumulation effects. However, from the alternative simulations' scenarios, instantaneous type of liberalization seems performing well in its capacity to increase real GDP, welfare, real output, and real export in the long run. This liberalization also recorded substantial decline in poverty level in the long run. Key words: Dynamic CGE Model, Trade Liberalization, Poverty, Growth, Ethiopia

description: We explore a simple solution to the cosmological challenges of the original Mirror Twin Higgs (MTH) model that leads to interesting implications for experiment. We consider theories in which both the standard model and mirror neutrinos acquire masses through the familiar seesaw mechanism, but with a low right-handed neutrino mass scale of order a few GeV. In these $ν$MTH models, the right-handed neutrinos leave the thermal bath while still relativistic. As the universe expands, these particles eventually become nonrelativistic, and come to dominate the energy density of the universe before decaying. Decays to standard model states are preferred, with the result that the visible sector is left at a higher temperature than the twin sector. Consequently the contribution of the twin sector to the radiation density in the early universe is suppressed, allowing the current bounds on this scenario to be satisfied. However, the energy density in twin radiation remains large enough to be discovered in future cosmic microwave background experiments. In addition, the twin neutrinos are significantly heavier than their standard model counterparts, resulting in a sizable contribution to the overall mass density in neutrinos that can be detected in upcoming experiments designed to probe the large scale structure of the universe.

description: As Physics did in previous centuries, there is currently a common dream of extracting generic laws of nature in economics, sociology, neuroscience, by focalising the description of phenomena to a minimal set of variables and parameters, linked together by causal equations of evolution whose structure may reveal hidden principles. This requires a huge reduction of dimensionality (number of degrees of freedom) and a change in the level of description. Beyond the mere necessity of developing accurate techniques affording this reduction, there is the question of the correspondence between the initial system and the reduced one. In this paper, we offer a perspective towards a common framework for discussing and understanding multi-level systems exhibiting structures at various spatial and temporal levels. We propose a common foundation and illustrate it with examples from different fields. We also point out the difficulties in constructing such a general setting and its limitations.
The Inverse Problem for the Dirichlet-to-Neumann map on Lorentzian manifolds

description: We consider the Dirichlet-to-Neumann map $Λ$ on a cylinder-like Lorentzian manifold related to the wave equation related to the metric $g$, a magnetic field $A$ and a potential $q$. We show that we can recover the jet of $g,A,q$ on the boundary from $Λ$ up to a gauge transformation in a stable way. We also show that $Λ$ recovers the following three invariants in a stable way: the lens relation of $g$, and the light ray transforms of $A$ and $q$. Moreover, $Λ$ is an FIO away from the diagonal with a canonical relation given by the lens relation. We present applications for recovery of $A$ and $q$ in a logarithmically stable way in the Minkowski case, and uniqueness with partial data.

description: We study the statistics of the local resolvent and non-ergodic properties of eigenvectors for a generalised Rosenzweig-Porter $N\times N$ random matrix model, undergoing two transitions separated by a delocalised non-ergodic phase. Interpreting the model as the combination of on-site random energies $\{a_i\}$ and a structurally disordered hopping, we found that each eigenstate is delocalised over $N^{2-γ}$ sites close in energy $|a_j-a_i|\leq N^{1-γ}$ in agreement with Kravtsov \emph{et al}, arXiv:1508.01714. Our other main result, obtained combining a recurrence relation for the resolvent matrix with insights from Dyson's Brownian motion, is to show that the properties of the non-ergodic delocalised phase can be probed studying the statistics of the local resolvent in a non-standard scaling limit.

description: We use HST/WFC3 imaging to study the red population in the IR-selected, X-ray detected, low-mass cluster Cl J1449+0856 at z=2, one of the few bona-fide established clusters discovered at this redshift, and likely a typical progenitor of an average massive cluster today. This study explores the presence and significance of an early red sequence in the core of this structure, investigating the nature of red sequence galaxies, highlighting environmental effects on cluster galaxy populations at high redshift, and at the same time underlining similarities and differences with other distant dense environments. Our results suggest that the red population in the core of Cl J1449+0856 is made of a mixture of quiescent and dusty star-forming galaxies, with a seedling of the future red sequence already growing in the very central cluster region, and already characterising the inner cluster core with respect to lower density environments. On the other hand, the color-magnitude diagram of this cluster is definitely different from that of lower-redshift (z<1) clusters, as well as of some rare particularly evolved massive clusters at similar redshift, and it is suggestive of a transition phase between active star formation and passive evolution occurring in the proto-cluster and established lower-redshift cluster regimes.

description: The gap equations for the surface quasiparticle propagators in a slab of three-dimensional topological insulator in external electric and magnetic fields perpendicular to the slab surfaces are analyzed and solved. A different type of magnetic catalysis is revealed with the dynamical generation of both Haldane and Dirac gaps. Its characteristic feature manifests itself in the crucial role that the electric field plays in dynamical symmetry breaking and the generation of a Dirac gap in the slab. It is argued that, for a sufficiently large external electric field, the ground state of the system is a phase with a homogeneous surface charge density.

description: Thresholds for beam damage have been assessed for La$_{0.7}$Sr$_{0.3}$MnO$_3$ and SrTiO$_3$ as a function of electron probe current and exposure time at 80 and 200 kV acceleration voltage. The materials were exposed to an intense electron probe by aberration corrected scanning transmission electron microscopy (STEM) with simultaneous acquisition of electron energy loss spectroscopy (EELS) data. Electron beam damage was identified by changes of the core loss fine structure after quantification by a refined and improved model based approach. At 200 kV acceleration voltage, damage in SrTiO$_3$ was identified by changes both in the EEL fine structure and by contrast changes in the STEM images. However, the changes in the STEM image contrast as introduced by minor damage can be difficult to detect under several common experimental conditions. No damage was observed in SrTiO$_3$ at 80 kV acceleration voltage, independent of probe current and exposure time. In La$_{0.7}$Sr$_{0.3}$MnO$_3$, beam damage was observed at both 80 and 200 kV acceleration voltages. This damage was observed by large changes in the EEL fine structure, but not by any detectable changes in the STEM images. The typical method to validate if damage has been introduced during acquisitions is to compare STEM images prior to and after spectroscopy. Quantifications in this work show that this method possibly can result in misinterpretation of beam damage as changes of material properties.
Analysis of Economic Growth, Income Distribution and Poverty in Ethiopia using CGE Model
Creators: name: Israel, Ephrem
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2006

description: This paper presents the nature of the links between economic growth, poverty and income distribution, a central question to the study of economic development. The model adapted was the simple non-dynamic Computable General Equilibrium (CGE) model developed by International Food Policy Research Institute (IFPRI) and those used by Cogneau and Robilliard. CGE model takes into account market interaction, that is, the effects of pricing outcomes of one market in other markets, and its effects, in turn, creating ripples throughout the whole economy, perhaps even to the extent of affecting the price-quantity equilibrium in the original market. The underlying Social Accounting Matrix (SAM), which provides initial values for variables and parameters in the model, is taken from Alemayehu and Tadeles' 1999 SAM. Given the limitations of CGE models, econometric estimations is carried out to handle the households agricultural production function using the Ethiopian Rural Household Survey (ERHS). To explore the impact of an increasing agricultural productivity on poverty and inequality, simulation exercises are performed. Then, the mean income elasticity of the Foster-Greer-Thorbeck (FGT) poverty indices are estimated to examine its poverty impact. Inequality effects are explored by estimating Gini index for rural and urban households by using the Generalized Quadratic (GQ) Lorenz curve. Key words: computable general equilibrium (CGE), growth, poverty, inequality
Cosmological thermodynamics with Hawking temperature on the apparent horizon and Unruh temperature of the fluid: Some interesting consequences

Year: 2016
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Thermodynamics on the cosmological apparent horizon of a flat Friedmann-Lemaitre-Robertson-Walker metric has been investigated with Bekenstein entropy and Hawking temperature on the horizon, and Unruh temperature for the fluid inside the horizon. This temperature is experienced by a radial comoving observer infinitesimally close to the horizon due to the pressure exerted by the fluid bounded by the horizon. An expression for the entropy of the fluid has been obtained which is found to be proportional to the volume of the thermodynamic system which implies that the Unruh temperature of the fluid is inconsistent with the holographic principle. Further, we have been able to find an expression for the effective entropy of the system. Finally, assuming a barotropic equation of state $p=wρ$ ($w$ constant) for the fluid, it has been shown that the generalized second law holds good for a non-phantom w, while thermodynamic equilibrium is never possible for such a scenario.

description: Atomic interferometry can be used to probe dark energy models coupled to matter. We consider the constraints coming from recent experimental results on models generalising the inverse power law chameleons such as $f(R)$ gravity in the large curvature regime, the environmentally dependent dilaton and symmetrons. Using the tomographic description of these models, we find that only symmetrons with masses smaller than the dark energy scale can be efficiently tested. In this regime, the resulting constraints complement the bounds from the Eötwash experiment and exclude small values of the symmetron self-coupling.

A Milky Way with a massive, centrally concentrated thick disc: new Galactic mass models for orbit computations

description: In this work, two new axisymmetric models for the Galactic mass distribution are presented. Motivated by recent results, these two models include the contribution of a stellar thin disc and of a thick disc, as massive as the thin counterpart but with a shorter scale-length. Both models satisfy a number of observational constraints: stellar densities at the solar vicinity, thin and thick disc scale lengths and heights, rotation curve(s), and the absolute value of the perpendicular force Kz as a function of distance to the Galactic centre. We numerically integrate into these new models the motion of all Galactic globular clusters for which distances, proper motions, and radial velocities are available, and the orbits of about one thousand stars in the solar vicinity. The retrieved orbital characteristics are compared to those obtained by integrating the clusters and stellar orbits in pure thin disc models. We find that, due to the possible presence of a thick disc, the computed orbital parameters of disc stars can vary by as much as 30-40%. We also show that the systematic uncertainties that affect the rotation curve still plague computed orbital parameters of globular clusters by similar amounts.

The Determinants of Household's Adoption of Solar Energy in Rural Ethiopia: The Case Study of Gurage Zone
Creators: name: Christian, Anteneh
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: In rural Ethiopian traditional fuels like kerosene and firewood are the main sources of energy used for lighting purpose. They are a major factor for environmental problems and health risks that affect the wellbeing of low-income rural households. However, Ethiopia has a vast potential for renewable energy resources like solar energy that have not fully utilized. The main aim of the study was to assess the determinants of household adoption of solar energy in the Gurage zone. In order to achieve the objective of the study, data were collected from 384 households using a survey questionnaire from Cheha and Ezha woredas. The collected survey data were analyzed by descriptive statistics and econometric model (probit model). The result of the probit model reveals that the adoption of solar energy has a positive and significant relation with household income, remittances, education, marital status and ownership of cattle. But the adoption of solar energy has a negative and significant relation with household size, sex, and age. Based on the findings, the study recommends that the government should enhance in poverty alleviation program in rural areas and improve rural household wealth, increase access to education and encourage women by giving especial service like credit access and creating awareness, to increase the adoption of solar energy technology.

description: The emergence of quantum consciousness stems from dynamic flows of hydrogen ions in brain liquid. This liquid contains vast areas of the fourth phase of water with hexagonal packing of its molecules, the so-called exclusion zone (EZ) of water. The hydrogen ion motion on such hexagonal lattices shows as the hopping of the ions forward and the holes (vacant places) backward, caused by the Grotthuss mechanism. By supporting this motion using external infrasound sources, one may achieve the appearance of the superfluid state of the EZ water. Flows of the hydrogen ions are described by the modified Navier-Stokes equation. It, along with the continuity equation, yields the nonlinear Schrodinger equation, which describes the quantum effects of these flows, such as the tunneling at long distances or the interference on gap junctions.

description: Song in zebra finches is an important mating signal- males learn a specific song from a “tutor” and eventually use it to attract a female, while females choose a mate based on their song preferences. Given that singing is a male-specific behavior, there is limited knowledge surrounding song learning ability in female zebra finches, as it was presumed that females are not receptive to song exposure during development. This study utilized fourteen female zebra finches to address whether early rearing conditions influence song preference in adulthood. Females were semi-randomly assigned to one of two conditions- “tutored” (exposure to the song of an unrelated male) or “isolated” (completely isolated from song). Song preference was tested with an operant conditioning perch-trigger assay, in which hopping on a perch triggered the playback of one of two songs. Results indicated that all “tutored” females (n = 7) significantly preferred the “familiar” song, or the song of the male that they had been exposed to during development, over an “unfamiliar” song of similar structure. The group of “isolated” females (n = 7) did not form a specific preference for one song over the other, and individually, they displayed varied preferences. These findings suggest that females are sensitive to song exposure throughout development, thus having implications for early song learning on mate choice in adulthood.
What Determines the Export Performance of Ethiopia: A Time Series Analysis
Creators: name: Muhabaw, Nega
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2013

description: This paper identified some of the main determinants of export performance in Ethiopia for the period 1974-2011.To test empirically the relationship between export performance and its major selected deter-minants such as terms of trade, trade openness, gross domestic product, real effective exchange rate, do-mestic credit and capital expenditure over a period. The results from the econometric analysis revealed that all the above listed explanatory variables signifi-cantly affected export performance in the long run except capital expenditure. In the short run, terms of trade became insignificant and negative in sign which was unexpected. Capital expenditure was also in-significant like in the case of long run. However, except these two variables other variables were found to significantly affect the export performance of the country. On the other hand, out of the variables signifi-cantly affected export both in the long run and short run; terms of trade, trade openness, and real gross domestic product affected export positively as expected. Especially when we look at the magnitude by which trade openness affected the dependent variable both in the long run and in the short run positively and significantly, it can be regarded as one of the key finding in this study.

description: We consider scenarios of Higgs compositeness where the Higgs doublet arises as a pseudo-Nambu Goldstone boson. Our focus is the physical scalar ("radial") excitation associated with the global symmetry breaking vacuum, which we call the "global Higgs". For the minimal case of a $SO(5)/SO(4)$ coset, the couplings of the global Higgs to Standard Model (SM) particles are fully determined by group theoretical factors and two decay constants. The global Higgs also couples to the composite resonances of the theory, inducing an interaction with the SM gauge bosons at one-loop. We thoroughly analyze representative fermionic sectors, considering a global Higgs both in the $\bf 5$ and $\bf 14$ representations of $SO(5)$ and taking into account the renormalization group evolution of couplings in the composite sector. We derive the one-loop effective couplings and all decays of the global Higgs, showing that its decay width over mass can range from $ O (10^{-3})$ to $ O(1)$. Because of the multiplicity of the resonances, the coupling of the global Higgs to gluons is sizeable, potentially opening a new window into composite models at the LHC.

Welfare Effects of Price Cap Regulation in comparison with Rate of Return Regulation: A Stochastic Frontier Analysis of Efficiency Costs of Flour Factories in Addis Ababa.
Creators: name: Tassew, Zelalem
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: This study aims at assessing the welfare effect of Price Cap Regulation that put in order by the government to regulate and ensure price stability for basic commodities supply in the market. In order to achieve the stated objective of the study, Stochastic Frontier Analysis of Efficiency Costs model is specified using the Cobb-Douglass Specification in its stochastic form. The parameters of the stochastic frontier functions are estimated using maximum likelihood that help to analyze the welfare effects of Price Cap Regulation. The data used for the estimation includes panel of 28 wheat flour factories in Addis Ababa from the period of May 2011 to April 2015. The major findings of the study show that Price Cap Regulation has improved the welfare of consumers as compared to the Rate of Return regulation. However, welfare distribution problem remains unsolved. The average capacity utilization of the flour mills remain as low as a quarter of their capacity and the supply of input wheat, which constitute the major cost of production of wheat flour as addressed by the government, is found to be not satisfactory. To improve efficiency of flour mills and the corresponding consumer welfare, supply of wheat need to be improved both in quantity and frequency terms. Furthermore, welfare distribution problem need to be addressed by enforcing the incentive scheme of flour mills based on the average not on the high cost firm. The study is made on the four year panel data of twenty eight flour factories situated in Addis Ababa. Such data helps to make comparative welfare effects in the study area, and to complement it, further research considering the regional flour mills and quality impact of price cap regulation can help to produce full effect assessment.

Einstein Static Universe and its Stability in Generalized Rastall Gravity

description: The Einstein static (ES) state is a good candidate for describing the very early universe in terms of a regular cosmological model in which the Big Bang singularity is avoided. In the present study we propose an ES solution in the framework of generalized Rastall gravity (GRG), a modified version of original Rastall theory in which the coupling parameter is allowed to vary with respect to the spacetime coordinates. Introducing an ansatz for the Rastall parameter, existence and the corresponding stability of the solutions are investigated. We show that the GRG is capable of describing a stable singularity-free state for the universe. The problem of transition from an ES to an inflationary state is also addressed. We find that a time variation of the equation of state parameter from values lying in the range |w|<1/3 to the value w=-1/3 can give rise to such a phase transition. The vector and tensor perturbations around the ES solution are studied, as well. In the case of GRG, the vector perturbations remain frozen, nevertheless, the tenor perturbations can grow in such a way that the ES solution remains stable provided the ratio of Rastall gravitational constant to the Einsteinian one always exceeds a minimum value for each tensor mode.

description: icro-finance institutions have made significant contributions to the livelihoods of many people through the provision of financial and supporting services to the poor, especially women in rural environments. Thus, it is understood that micro-financing, as a development strategy, empowers women who were hitherto marginalized, and as such, were restricted from participating in the social, economic and political activities of their societies. This study examined the impact of Amhara Credit and Saving Institutions' (ACSI's) micro-financing service on women's economic empowerment. Data was collected from a total of 171 rural women consisting of 54 Matured Clients, 33 Incoming Clients, and 26 Dropouts (ex-Clients) in ACSI program areas; and 16 and 42 non-clients in program and non-program areas respectively situated in Kobo Woreda, Amhara National Regional State. The empirical analysis of the study was conducted using both descriptive statistics and Binomial Logit regression analysis. The results of the study indicate that the micro-financing scheme has a positive impact on women's economic empowerment as measured by the increased participation of women in household decision-making. ACSI's program has had a positive impact on the living conditions of its clients. Compared to the Incoming clients and non-clients, matured clients of ACSI have improved their household incomes, asset possession levels, and savings habit; thereby positively affecting their ability to fully participate in household decision-making. However, the impact of improvement of the above three variables; income, asset possession and savings habit, does not significantly affect the variable "decision making on household large sales", which was used as an indicator of women's economic empowerment in the regression analysis. The implication of the findings is that giving women access to resources does not always mean empowering them economically, unless they can also exercise full control, and make important decisions, over their resources. Thus, beyond financial support, the contribution of micro-finance services to women's economic empowerment should be enhanced through a combination of more effective support services of MFIs or linkages should be made with services provided by other agencies like the Woreda Women's Affaire' Office and other gender-focused organizations.

description: With the NIST post-quantum standardization competition entering the second round, the interest in practical implementation results of the remaining NIST candidates is steadily growing. Especially implementations on embedded devices are often not protected against side-channel attacks, such as differential power analysis. In this regard, the application of countermeasures against side-channel attacks to candidates of the NIST standardization process is still an understudied topic. Our work aims to contribute to the NIST competition by enabling a more realistic judgment of the overhead cost introduced by side-channel countermeasures that are applied to lattice-based KEMs that achieve CCA-security based on the Fujisaki-Okamoto transform. We present a novel higher-order masking scheme that enables an efficient comparison of polynomials as previous techniques based on arithmetic-to-Boolean conversions renders this (generally inexpensive) component extremely expensive in the masked case. Our approach has linear complexity in the number of shares compared to quadratic complexity of previous contributions and it applies to lattice based schemes with prime modulus. It comes with a proof in the probing model and an efficient implementation on an ARM Cortex-M4F microcontroller which was defined as a preferred evaluation platform for embedded implementations by NIST. Our algorithm can be executed in only 1.5-2.2 milliseconds on the target platform (depending on the masking order) and is therefore well suited even for lightweight applications. While in previous work, practical side-channel experiments were conducted using only 5,000 - 100,000 power traces, we confirm the absence of first-order leakage in this work by collecting 1 million power traces and applying the t-test methodology.

description: The goal of white-box cryptography is to protect secret keys embedded in a cryptographic software deployed in an untrusted environment. In this article, we revisit state-of-the-art countermeasures employed in white-box cryptography, and we discuss possible ways to combine them. Then we analyze the different gray-box attack paths and study their performances in terms of required traces and computation time. Afterward, we propose a new paradigm for the gray-box attack against white-box cryptography, which exploits the data-dependency of the target implementation. We demonstrate that our approach provides substantial complexity improvements over the existing attacks. Finally, we showcase this new technique by breaking the three winning AES-128 white-box implementations from WhibOx 2019 white-box cryptography competition.

description: At EUROCRYPT 2004, Naccache et al. showed that the projective coordinates representation of the resulting point of an elliptic curve scalar multiplication potentially allows to recover some bits of the scalar. However, this attack has received little attention by the scientific community, and the status of deployed mitigations to prevent it in widely adopted cryptography libraries is unknown. In this paper, we aim to fill this gap, by analyzing several cryptography libraries in this context. To demonstrate the applicability of the attack, we use a side-channel attack to exploit this vulnerability within libgcrypt in the context of ECDSA. To the best of our knowledge, this is the first practical attack instance. It targets the insecure binary extended Euclidean algorithm implementation using a microarchitectural side-channel attack that allows recovering the projective representation of the output point of scalar multiplication during ECDSA signature generation. We captured 100k traces to estimate the number of traces an attacker would need to compromise the libgcrypt ECDSA implementation, resulting in less than 2k for commonly used elliptic curve secp256r1, demonstrating the attack feasibility. During exploitation, we found two additional vulnerabilities. However, we remark the purpose of this paper is not merely exploiting a library but about providing an analysis on the projective coordinates vulnerability status in widely deployed open-source libraries, filling a gap between its original description in the academic literature and the adoption of countermeasures to thwart it in real-world applications.

description: The GIFT family of lightweight block ciphers, published at CHES 2017, offers excellent hardware performance figures and has been used, in full or in part, in several candidates of the ongoing NIST lightweight cryptography competition. However, implementation of GIFT in software seems complex and not efficient due to the bit permutation composing its linear layer (a feature shared with PRESENT cipher). In this article, we exhibit a new non-trivial representation of the GIFT family of block ciphers over several rounds. This new representation, that we call fixslicing, allows extremely efficient software bitsliced implementations of GIFT, using only a few rotations, surprisingly placing GIFT as a very efficient candidate on micro-controllers. Our constant time implementations show that, on ARM Cortex-M3, 128-bit data can be ciphered with only about 800 cycles for GIFT-64 and about 1300 cycles for GIFT-128 (assuming pre-computed round keys). In particular, this is much faster than the impressive PRESENT implementation published at CHES 2017 that requires 2116 cycles in the same setting, or the current best AES constant time implementation reported that requires 1617 cycles. This work impacts GIFT, but also improves software implementations of all other cryptographic primitives directly based on it or strongly related to it.

description: The sensitivity of astronomical X-ray detectors is limited by the instrumental background. The background is especially important when observing low surface brightness sources that are critical for many of the science cases targeted by future X-ray observatories, including Athena and future US-led flagship or probe-class X-ray missions. Above 2keV, the background is dominated by signals induced by cosmic rays interacting with the spacecraft and detector. We develop novel machine learning algorithms to identify events in next-generation X-ray imaging detectors and to predict the probability that an event is induced by a cosmic ray vs. an astrophysical X-ray photon, enabling enhanced filtering of the cosmic ray-induced background. We find that by learning the typical correlations between the secondary events that arise from a single primary, machine learning algorithms are able to successfully identify cosmic ray-induced background events that are missed by traditional filtering methods employed on current-generation X-ray missions, reducing the unrejected background by as much as 30 per cent.
