The impact of international financial Reporting standard (IFRS) adoption on key Financial ratios – the case of private commercial banks in Ethiopia
Creators: name: Manalebih, Mequanint
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: This study examines the impact IFRS adoption on key financial ratios on commercial banks in Ethiopia with objectives of ascertaining the role of IFRS for quality accounting information, identifying the sources of differences in financial reporting experienced by banks, examining whether the differences between GAAP and IFRS exist. The study employs a quantitative research approach based on financial information's and figures collected from banks annual audited reports. Sixteen banks were selected out of eighteen commercial banks. To understand the impact of IFRS adoption on banks financial ratios and figures, data were collected and summarized in excels, test and analyzed in SPSS. Figures and ratios were tested and analyzed through descriptive statistics, test of equality of means, median and variances and regression analysis. The descriptive statistics result indicates most of the range of values is larger in IFRS compared to that in GAAP. The test equality of means and medians results not statistically rejected for all figures .IFRS adoption does not change significantly, at the aggregate level. The median value of revenue indicates that there is no difference in Revenue between GAAP and IFRS, and Revenue does not have any impact on differences between ratios. Some financial statement figures decreased and others increase after the transition. Profit for the year increase and inconsistent to the research problems that profit decreases after the transition from GAAP to IFRS by banks. The IFRS values are not fully explained by GAAP in regression analysis. The study suggests that at the aggregate level, the analysis of medians and means of IFRS values is generally reliable; the volatility of accounting figures in IFRS is generally higher than GAAP. Various adjustments affect the differences between financial statement figures and ratios in IFRS and GAAP. It may be prudent to rely on cash flows to avoid the subjectivity inherent to accounting adjustments. IFRS adoption is new to Ethiopia, the impact of IFRS on financial statement figures, ratios, and earnings may not be observed and understood at this time and it needs further studies by taking more trend data in the future.

description: Hoje tornou-se comum a convivência com robôs, já que estes são capazes de realizar desde uma simples à mais complexa tarefa. Robôs são criados para a execução de diversas atividades, dentre elas podemos citar, função doméstica, busca e resgate, vigilância, ou um simples empilhar de caixas. Assim, a robótica coletiva tonou-se valiosa, por permitir a realização de tarefas com maior agilidade e confiabilidade que um único robô centralizado. Neste contexto a presente pesquisa objetiva criar um algoritmo capaz de controlar um time de robôs para que eles realizem de forma autônoma, ciclos de vigilância, adaptando-se a novos ambientes e escolhendo os melhores trajetos. A fim de solucionar essa tarefa foram utilizados técnicas bio-inspiradas, tais como inteligência de enxames, autômatos celulares e inteligência de colônia de formigas. Os robôs se movimentam no mesmo ambiente e comunicam-se através do feromônio invertido das formigas, ou seja, a cada passo de tempo eles depositam uma certa quantia de feromônio em suas células vizinhas, sendo o depósito somente nas células livres, sem obstáculos. Portanto, a probabilidade de visitarem uma célula com alta quantia de feromônio é baixa, por conseguinte, a chance de visitarem uma célula com baixa quantia de feromônio é alta. Ao final o feromônio invertido faz que os robôs evitem a repetição de posições, obtendo um resultado mais equilibrado. Com a intenção de verificar a eficácia do algoritmo vários experimentos foram realizados em diferentes ambientes com tamanhos e quantidade de cômodos variados, com o objetivo de averiguar a sua adaptação a novos ambientes. Em seguida, o número de iterações foi variado entre 10 3 , 10 4 e 10 5 , ao passo que a cada passo o robô era inicializado em diferentes posições. A partir disso, temos que um time de robôs se torna mais efetivo no seu presente ambiente, à medida que ao final das iterações estipuladas todos os cômodos tivessem sido vigiados o maior número de vezes. É valido ressaltar que, um único robô demoraria muitas iterações para conseguir verificar todos os cômodos pelo menos uma vez. Como conclusão, pudemos perceber, a importância do usa da robótica de enxames, que realiza tarefas complexas de forma paralelística, gastando um menor tempo para o desempenho de um determinado objetivo.

description: Mobile apps are becoming popular educational tools due to their accessibility, interactivity and ability to provide personalised learning. Numerous apps are now available for healthcare professionals, including in the area of medical education and training. But until now, the number of PHTLS apps available for health professionals or information on their features was not known.PHTLS is the emergency support provided for trauma patients involving their immediate care and transport. It is indispensable for the early identification and management of life-endangering trauma.Researchers in Peru conducted a systematic search of the Apple Store, BlackBerry World, and the Google Play Store in December 2015 for all English and Spanish mobile apps that at least provided information on the airway, breathing and circulation (ABC) first-aid procedure for PHTLS. They found a total of 41 mobile apps.Less than half these apps were free, among which only a few had interactive content (30%). Also, few of the free apps (30%) were institutionally certified, which means the credibility of their content cannot be guaranteed. An Internet connection was not required for most free apps (85%) to be fully functional, a feature that could be considered useful for professionals working in pre-hospital environments where Internet connections can be weak or unavailable, say the researchers.The team did not have access to information on PHTLS training apps that cost money, so they were unable to evaluate their features and compare them with those of free apps. Nevertheless, the team believes this to be the first study that has evaluated the features of mobile apps for PHTLS. Designers of these apps, PHTLS professionals and researchers in the field of wireless and mobile technologies in medical care should take the study’s findings into consideration when designing and using them, the researchers conclude in their study published in the Journal of Emergency Medicine, Trauma & Acute Care.Other InformationPublished in: QScience.com Highlights, Published by Nature Research for Hamad bin Khalifa University Press (HBKU Press)

description: Using a modification of the Shapiro approach, we introduce the two-parameter family of conductance distributions W(g), defined by simple differential equations, which are in the one-to-one correspondence with conductance distributions for quasi-one-dimensional systems of size L^{d-1}\times L_z, characterizing by parameters L/ξand L_z/L (ξis the correlation length, d is the dimension of space). This family contains the Gaussian and log-normal distributions, typical for the metallic and localized phases. For a certain choice of parameters, we reproduce the results for the cumulants of conductance in the space dimension d=2+εobtained in the framework of the σ-model approach. The universal property of distributions is existence of two asymptotic regimes, log-normal for small g and exponential for large g. In the metallic phase they refer to remote tails, in the critical region they determine practically all distribution, in the localized phase the former asymptotics forces out the latter. A singularity at g=1, discovered in numerical experiments, is admissible in the framework of their calculational scheme, but related with a deficient definition of conductance. Apart of this singularity, the critical distribution for d=3 is well described by the present theory. One-parameter scaling for the whole distribution takes place under condition, that two independent parameters characterizing this distribution are functions of the ratio L/ξ.

description: Diffusion models have proven effective for various applications such as images, audio and graph generation. Other important applications are image super-resolution and the solution of inverse problems. More recently, some works have used stochastic differential equations (SDEs) to generalize diffusion models to continuous time. In this work, we introduce SDEs to generate super-resolution face images. To the best of our knowledge, this is the first time SDEs have been used for such an application. The proposed method provides an improved peak signal-to-noise ratio (PSNR), structural similarity index measure (SSIM), and consistency than the existing super-resolution methods based on diffusion models. In particular, we also assess the potential application of this method for the face recognition task. A generic facial feature extractor is used to compare the super-resolution images with the ground truth and superior results were obtained compared with other methods.

description: The present work addresses the distinction between the topological properties of PT symmetric and non-PT symmetric scenarios for the non-Hermitian Su-Schrieffer-Heeger (SSH) model. The non-PT symmetric case is represented by non-reciprocity in both the inter- and the intra-cell hopping amplitudes, while the one with PT symmetry is modeled by a complex on-site staggered potential. In particular, we study the loci of the exceptional points, the winding numbers, band structures, and explore the breakdown of bulk-boundary correspondence (BBC). We further study the interplay of the dimerization strengths on the observables for these cases. The non-PT symmetric case denotes a more familiar situation, where the winding number abruptly changes by a half-integer through tuning of the non-reciprocity parameters, and demonstrates a complete breakdown of BBC, thereby showing the non-Hermitian skin effect. The topological nature of the PT symmetric case appears to follow closely to its Hermitian analogue, except that it shows unbroken (broken) regions with complex (purely real) energy spectra, while another variant of the winding number exhibits a continuous behavior as a function of the strength of the potential, while the conventional BBC is preserved.

description: Sunspots are concentrations of magnetic field visible on the solar surface (photosphere). It was considered implausible that solar flares, as resulted from magnetic reconnection in the tenuous corona, would cause a direct perturbation of the dense photosphere involving bulk motion. Here we report the sudden flare-induced rotation of a sunspot using the unprecedented spatiotemporal resolution of the 1.6 m New Solar Telescope, supplemented by magnetic data from the Solar Dynamics Observatory. It is clearly observed that the rotation is non-uniform over the sunspot: as the flare ribbon sweeps across, its different portions accelerate (up to 50 deg per hr) at different times corresponding to peaks of flare hard X-ray emission. The rotation may be driven by the surface Lorentz-force change due to the back reaction of coronal magnetic restructuring and is accompanied by a downward Poynting flux. These results have direct consequences for our understanding of energy and momentum transportation in the flare-related phenomena.

description: In this work, we have investigated the precursor effects to superconductivity in BaPb$_{0.75}$Bi$_{0.25}$O$_3$ using temperature dependent resistivity, x-ray diffraction technique and photoemission spectroscopy. The present compound exhibits superconductivity around 11 K ($T_C$). The synthesis procedure adopted is much simpler as compared to the procedure available in the literature. In the temperature range (10 K-25 K) i.e. above $T_C$, our results show an increase in both the orthorhombic and tetragonal strain. The well screened features observed in Bi and Pb 4$f_{7/2}$ core levels are indicative of the metallic nature of the sample. The compound exhibits finite intensity at the Fermi level at 300 K and this intensity decreases with decrease in temperature and develops into a pseudogap; the energy dependence of the spectral density of states suggests disordered metallic state. Furthermore, our band structure calculations reveal that the structural transition upon Pb doping results in the closing of the band gap at the Fermi level.

description: Using the Keldysh Green function technique, we calculate the finite-frequency correlator between the electrical current and the heat current flowing through a quantum dot connected to reservoirs. At equilibrium, we find that this quantity, called mixed noise, is linked to the thermoelectric ac-conductance by the fluctuation-dissipation theorem. Out-of-equilibrium, we discuss its spectrum and find evidence of the close relationship between the mixed noise and the thermopower. We study the spectral coherence and identify the conditions to have a strong correlation between the electrical and heat currents. The change in the spectral coherence due to the presence of a temperature gradient between the reservoirs is also highlighted.

description: The continued growth in the processing power of FPGAs coupled with high bandwidth memories (HBM), makes systems like the Xilinx U280 credible platforms for linear solvers which often dominate the run time of scientific and engineering applications. In this paper, we present Callipepla, an accelerator for a preconditioned conjugate gradient linear solver (CG). FPGA acceleration of CG faces three challenges: (1) how to support an arbitrary problem and terminate acceleration processing on the fly, (2) how to coordinate long-vector data flow among processing modules, and (3) how to save off-chip memory bandwidth and maintain double (FP64) precision accuracy. To tackle the three challenges, we present (1) a stream-centric instruction set for efficient streaming processing and control, (2) vector streaming reuse (VSR) and decentralized vector flow scheduling to coordinate vector data flow among modules and further reduce off-chip memory accesses with a double memory channel design, and (3) a mixed precision scheme to save bandwidth yet still achieve effective double precision quality solutions. To the best of our knowledge, this is the first work to introduce the concept of VSR for data reusing between on-chip modules to reduce unnecessary off-chip accesses for FPGA accelerators. We prototype the accelerator on a Xilinx U280 HBM FPGA. Our evaluation shows that compared to the Xilinx HPC product, the XcgSolver, Callipepla achieves a speedup of 3.94x, 3.36x higher throughput, and 2.94x better energy efficiency. Compared to an NVIDIA A100 GPU which has 4x the memory bandwidth of Callipepla, we still achieve 77% of its throughput with 3.34x higher energy efficiency.

We discuss five major topics including: (1) Development of phase coherence and two-stage hybridization; (2) Two-fluid behavior and hidden universal scaling; (3) Quantum phase transitions and fractionalized heavy fermion liquid; (4) Quantum critical superconductivity; (5) Material-specific properties. These cover the most essential parts of heavy fermion physics and lead to an emerging global picture beyond conventional theories based on mean-field or local approximations.

description: Non-interacting particles obeying certain fractional statistics have been predicted to exhibit superconductivity. We discuss the issue in an attractively interacting system of spinful semions on a lattice by numerically investigating the presence of off-diagonal long-range order at zero temperature. For this purpose, we construct a Hubbard model wherein two semions with opposite spin can virtually coincide while maintaining consistency with the fractional braiding statistics. Clear off-diagonal long range order is seen in the strong coupling limit, consistent with the expectation that a pair of semions obeys Bose statistics. We find that the semion system behaves similarly to a system of fermions with the same attractive Hubbard $U$ interaction for a wide range of $U$, suggesting that semions also undergo a BCS to BEC crossover as a function of $U$.

description: We prove several identities expressing polynomials counting permutations by various descent statistics in terms of Eulerian polynomials, extending results of Stembridge, Petersen, and Brändén. Additionally, we find $q$-exponential generating functions for $q$-analogues of these descent statistic polynomials that also keep track of the inversion number or inverse major index. We also present identities relating several of these descent statistic polynomials to refinements of type B Eulerian polynomials and flag descent polynomials by the number of negative letters of a signed permutation. Our methods include permutation enumeration techniques involving noncommutative symmetric functions, Brändén's modified Foata-Strehl action, and a group action of Petersen on signed permutations. Notably, the modified Foata-Strehl action yields an analogous relation between Narayana polynomials and the joint distribution of the peak number and descent number over 231-avoiding permutations, which we also interpret in terms of binary trees and Dyck paths.

description: A correta evacuação de pedestres em ambientes fechados e sob incêndio é fundamental para assegurar a integridade física de todos os ocupantes de um determinado espaço. A modelagem de tais situações vêm sendo um tema recorrente em trabalhos nos últimos anos, onde se destacam o uso de Autômatos Celulares (ACs). Um AC é constituído por um reticulado de d dimensões, dividido em células de mesmo tamanho e que apresentam um determinado estado. A partir de uma regra de transição, é possível obter o estado das células em cada momento t e quando a aplicamos por T passos de tempo, obtemos a evolução espaço-temporal do AC. O presente projeto consiste na implementação de um modelo híbrido, composto pelo modelo determinístico de Varas e por uma parte estocástica, proposta neste trabalho, para a escolha do movimento do pedestre. Em seguida, será feita a comparação entre os modelos citados e outros existentes, com e sem a presença de fogo. O desenvolvimento da aplicação é realizado a partir da linguagem de programação C padrão e os testes são executados no terminal da distribuição do Ubuntu. Até o presente momento, o modelo de Varas foi implementado e três análises diferentes foram realizadas, uma das quais com presença de fogo. Nos dois primeiros blocos de teste, que contaram com, respectivamente, uma e duas saídas, foi identificada uma grande formação de filas na frente das portas. Foi também constatado que saídas próximas aos cantos da sala tendem a ter um desempenho pior em comparação às que estão mais ao meio de uma parede. Adicionalmente, foi constatado que quanto mais perto duas portas estão uma da outra, pior é o desempenho do caso, devido à distribuição dos pedestres ser aglomerada num mesmo ponto. Por fim, no último bloco de testes, que contou com a presença do fogo, manteve-se os fenômenos apresentados acima e verificou-se que o fogo funciona como uma espécie de obstáculo para os pedestres, o atrasando em sua tentativa de sair da sala. Isso ocasiona em simulações onde o desvio absoluto é muito acentuado. Como conclusão temos que ao criar uma estrutura predial, essas situações de escolha de onde as portas devem ser inseridas deve ser considerada e melhorar o processo de evacuação de pedestres.

title: A Taste for Ethics: Shifting from Lifestyle to a Way of Life
Creators: name: Tam Dic Sze, Daisy
Publisher: name: Goldsmiths, University of London
Year: 2009

description: This thesis concerns contemporary food movements and practices in the UK, their relation to lifestyle and consumption on the one hand, and to "way of life" on the other. Recent attention to food practices has indicated a shift in consumptive behaviour: increased concern for the welfare of the environment, animals and people who work in the industry, as well as for the quality of food, have made labels such as "good", "clean" and "fair" (associated with "quality", "organic" and "fair-trade") buzz-words in the industry. Through fieldwork (4 years' participant observation as a weekend trader for a local fruit producer in Borough Market, London), theoretical engagement and media analysis, the thesis critically evaluates the privileged status that these terms are given and aims to differentiate the changes that benefit individual stylised living (lifestyles) from those which contribute to the betterment of society (way of life). This thesis takes four sites in which ethical food consumption is emphasized: the Slow Food movement, supermarkets, farmers' markets and the community garden; and critically evaluates their responses to these concerns in a theoretical context based on the cultural analysis of the everyday, drawing on thinkers including Henri Lefebvre, Michel Foucault, Michel de Certeau, Jacques Derrida and others. A different model for addressing questions ofethical consumption arises from each empirical study: every model is critically evaluated on the basis of a combination of theory and experiences drawn from fieldwork, revealing certain limitations which move the investigation forward to the next site - in this sense the thesis develops dialectically through particular cases towards addressing the general problematic of ethical living in the everyday. It concludes by taking the model of a community garden, contextualised by a discussion of the commons, as an outline for addressing the problematic of ethical consumption in its widest social context, and as an indication of the possible direction of subsequent research.

In this paper, we further consider this problem and point out two weaknesses of ViTs in inductive biases, that is, the spatial relevance and diverse channel representation. First, on spatial aspect, objects are locally compact and relevant, thus fine-grained feature needs to be extracted from a token and its neighbors. While the lack of data hinders ViTs to attend the spatial relevance. Second, on channel aspect, representation exhibits diversity on different channels. But the scarce data can not enable ViTs to learn strong enough representation for accurate recognition. To this end, we propose Dynamic Hybrid Vision Transformer (DHVT) as the solution to enhance the two inductive biases. On spatial aspect, we adopt a hybrid structure, in which convolution is integrated into patch embedding and multi-layer perceptron module, forcing the model to capture the token features as well as their neighboring features. On channel aspect, we introduce a dynamic feature aggregation module in MLP and a brand new "head token" design in multi-head self-attention module to help re-calibrate channel representation and make different channel group representation interacts with each other. The fusion of weak channel representation forms a strong enough representation for classification. With this design, we successfully eliminate the performance gap between CNNs and ViTs, and our DHVT achieves a series of state-of-the-art performance with a lightweight model, 85.68% on CIFAR-100 with 22.8M parameters, 82.3% on ImageNet-1K with 24.0M parameters.

description: Important spectral features, such as the emptiness of the residual spectrum, countability of the point spectrum, provided the space is separable, and a characterization of spectral gap at $0$, known to hold for bounded scalar type spectral operators, are shown to naturally transfer to the unbounded case.
Possible molecular states of $\bar D^{*}K^{*}$ ($ D^{*}K^{*}$) and the new exotic states $X_0(2900)$ and $X_1(2900)$ ($T^a_{cs0}(2900)^0$ and $T^a_{cs0}(2900)^{++}$)

description: Two iso-singlet hadron states $X_0(2900)$ and $X_1(2900)$ with $J=0$ and 1 respectively, discovered by the LHCb collaboration in 2020, were identified as molecular bound states of $\bar D^*K^*$. Recently two structures $T^a_{cs0}(2900)^0$ and $T^a_{cs0}(2900)^{++}$ have been observed at the hadron spectra, one would suspect if they also are molecular states of $D^*$ and $K^*$. As long as they were of the molecular structures of $D^*K^*$, the hadron states must be in an iso-vector, namely $T^a_{cs0}(2900)^0$ and $T^a_{cs0}(2900)^{++}$ were $I_3=-1, 1$ components of the iso-vector. If it is the case, the corresponding $T^a_{cs0}(2900)^+$ of ($I=1,I_3=0$) and $T^{'a}_{cs0}(2900)^{+}$ of $I=0,I_3=0$ so far evade experimental observation, but should be found by the future experiments. To testify this ansatz, in this paper we study the possible molecular structures of $\bar D^{*}K^{*}$ and $D^{*}K^{*}$ within the Bethe-Salpeter (B-S) framework. With reasonable input parameters it is found that $\bar D^{*}K^{*}$ iso-scalar systems with $J^P=0^+$ and $1^+$ are solutions. The result supports the ansatz of $X_0(2900)$ ($X_1(2900)$) being molecular states of $\bar D^*K^{*}$. Whereas for the system of $ D^{*}K^{*}$ with $I=1$ the corresponding B-S equation has no solution. Thus we can draw a clear conclusion that $T^a_{cs0}(2900)^0$ and $T^a_{cs0}(2900)^{++}$ should not be bound states of $ D^{*}$ and $K^{*}$. The two structures observed by the LHCb collaboration may be caused by dynamics, such as the well-recognized triangle anomalies or other mechanisms.

description: Malware checking is changing from being a local service to a cloud-assisted one where users' devices query a cloud server, which hosts a dictionary of malware signatures, to check if particular applications are potentially malware. Whilst such an architecture gains all the benefits of cloud-based services, it opens up a major privacy concern since the cloud service can infer personal traits of the users based on the lists of applications queried by their devices. Private membership test (PMT) schemes can remove this privacy concern. However, known PMT schemes do not scale well to a large number of simultaneous users and high query arrival rates. We propose a simple PMT approach using a carousel: circling the entire dictionary through trusted hardware on the cloud server. Users communicate with the trusted hardware via secure channels. We show how the carousel approach, using different data structures to represent the dictionary, can be realized on two different commercial hardware security architectures (ARM TrustZone and Intel SGX). We highlight subtle aspects of securely implementing seemingly simple PMT schemes on these architectures. Through extensive experimental analysis, we show that for the malware checking scenario our carousel approach surprisingly outperforms Path ORAM on the same hardware by supporting a much higher query arrival rate while guaranteeing acceptable response latency for individual queries.

description: Salmonellosis is a common type of food poisoning caused by Salmonella bacteria. It affects tens of millions and kills more than 100,000 people every year worldwide. It occurs by eating contaminated food and results in diarrhoea, fever and stomach cramps 12 to 72 hours after infection. The condition is usually self-limiting, requiring only adequate rehydration without the need for antibiotic treatment. However, in some cases the diarrhoea and consequent dehydration can be so severe that hospitalization becomes necessary.Researchers in Qatar reviewed physician and laboratory reports of salmonella cases in the country between 2004 and 2012 and found a high incidence of salmonellosis in the country. The trend was generally decreasing during the investigated time period, which can be attributed to improvements in the food chain and sanitation in the country, they say.The incidence rate of salmonellosis in Qatar in 2012 was 18.1 per 100,000. This rate is comparable to others in countries such as Canada (19.4/100,000), Poland (22.9/100,000) and the US (16.4/100,000).In 2012, half the cases in Qatar were girls below the age of two and boys below the age of three. Three-fourths of the cases in that same year were non-Qataris, with Indians, Egyptians and Pakistanis forming a large bulk of those affected. The highest incidence of cases was between May and September, which can be attributed to a known increased risk of gastrointestinal diseases when temperatures rise.Interestingly, the team found more than 40% of the Salmonella strains tested in 2012 to be resistant to five different antibiotics. Resistance in Salmonella strains often occurs due to the use of antimicrobial drugs in animal feed. Animals are the main reservoir of this bacterium. But a low-resistance pattern was found for two other commonly used antibiotics (cephalosporin and ciprofloxacin).“Special intervention and health awareness programs are required for early screening, detection and treatment as well as the need for strengthening the surveillance system of salmonellosis, with special emphasis on the laboratory study of cases,” conclude the researchers in their article published in the Qatar Medical Journal.Other InformationPublished in: QScience.com Highlights, Published by Nature Research for Hamad bin Khalifa University Press (HBKU Press)

description: Relying on the Penrose process mechanism, we study the possibility of energy extraction from a binary system composed of two extreme electrostatic black holes (BHs) oppositely charged, separated by a strut described by Bonnor's metric (BM). We determined and plotted the generalized ergosphere that surrounds only one of the BH. We demonstrate the existence of non closed orbits of negative energy outside the event horizon; these orbits allow the possibility of energy extraction by particle disintegration from a system described by the BM. Besides we prove that the extraction process can occur when a charged test particle and the BH have opposite charges; also, we analyzed the efficiency of the process.

description: Detector studies for future experiments rely on advanced software tools to estimate performance and optimize their design and technology choices. The Key4hep project provides a flexible turnkey solution for the full experiment life-cycle based on established community tools such as ROOT, Geant4, DD4hep, Gaudi, podio and spack. Members of the CEPC, CLIC, EIC, FCC, and ILC communities have joined to develop this framework and have merged, or are in the progress of merging, their respective software environments into the Key4hep stack. These proceedings will give an overview over the recent progress in the Key4hep project: covering the developments towards adaptation of state-of-the-art tools for simulation (DD4hep, Gaussino), track and calorimeter reconstruction (ACTS, CLUE), particle flow (PandoraPFA), analysis via RDataFrame, and visualization with Phoenix, as well as tools for testing and validation.
