description: We present radio observations of the tidal disruption event candidate (TDE) XMMSL1 J0740$-$85 spanning 592 to 875 d post X-ray discovery. We detect radio emission that fades from an initial peak flux density at 1.6 GHz of $1.19\pm 0.06$ mJy to $0.65\pm 0.06$ mJy suggesting an association with the TDE. This makes XMMSL1 J0740$-$85 at $d=75$ Mpc the nearest TDE with detected radio emission to date and only the fifth TDE with radio emission overall. The observed radio luminosity rules out a powerful relativistic jet like that seen in the relativistic TDE Swift J1644+57. Instead we infer from an equipartition analysis that the radio emission most likely arises from a non-relativistic outflow similar to that seen in the nearby TDE ASASSN-14li, with a velocity of about $10^4$ km s$^{-1}$ and a kinetic energy of about $10^{48}$ erg, expanding into a medium with a density of about $10^2$ cm$^{-3}$. Alternatively, the radio emission could arise from a weak initially-relativistic but decelerated jet with an energy of $\sim 2\times 10^{50}$ erg, or (for an extreme disruption geometry) from the unbound debris. The radio data for XMMSL1 J0740$-$85 continues to support the previous suggestion of a bimodal distribution of common non-relativistic isotropic outflows and rare relativistic jets in TDEs (in analogy with the relation between Type Ib/c supernovae and long-duration gamma-ray bursts). The radio data also provide a new measurement of the circumnuclear density on a sub-parsec scale around an extragalactic supermassive black hole.

description: Achieving hardware-specific implementation and optimization while maintaining productivity in an increasingly diverse environment of supercomputing architectures is challenging and requires rethinking traditional numerical weather prediction model programming designs. We provide insights into the ongoing porting and development of ECMWF’s non-hydrostatic FVM atmospheric dynamical core option in Python with the domain-specific library GT4Py. The presentation highlights the GT4Py approach for implementing weather and climate models, shows preliminary high-performance computing results on CPUs and GPUs for FVM and other ECMWF relevant codes, and outlines the roadmap for the overall model porting project with partners at CSCS and ETH Zurich.
title: Evaluating Passivhaus EnerPHit Retrofit Strategies for Low-Rise Suburban Dwellings in China's Hot Summer - Cold Winter Climate Region
Creators: name: Liu, Chenfei
Publisher: name: University of Liverpool Repository

description: China is the largest energy consumer in the world, and the biggest source of energy demand in China is the building sector, which accounts for 46.5% of the country's total energy consumption and 51.3% of carbon emissions. The area with the fastest growth in building energy demand in the country is the central southern hot summer - cold winter climate region. The Passivhaus standard (and its retrofit equivalent EnerPHit) focusses on achieving ultra-low operational energy consumption. However, examples of Passivhaus and EnerPHit buildings are rare for hot climates, and this particularly true for China. When improving the energy performance of an existing building, it is also important to consider the environmental impact of any retrofit building materials that are used as part of an EnerPHit retrofitting programme. Therefore, this study investigated the energy savings, carbon emission reductions and cost savings that might accrue from retrofitting, to the EnerPHit standard, a case study dwelling located in China’s hot summer - cold winter climate region. External weather and indoor thermal conditions of the case building were monitored for 12 months, and these data were used to validate a digital model of the dwelling. The model was used to evaluate retrofitting to the EnerPHit standard, which gave energy savings of 90.1% for heating and 72.6% for cooling compared with the pre-retrofit condition. Next, different combinations of retrofitting measures were evaluated for four different build scenarios to find how the EnerPHit criteria could be met using fewer building materials. Lastly, the finalized retrofitting plans for the case building were evaluated from the carbon and cost points of view, through detailed life cycle carbon and cost assessments. The results showed that the carbon payback time of the proposed retrofitting plans was much faster than the cost payback time, and that at the end of the evaluated lifespan, savings of up to 83.4% of the carbon emissions and 18% of the costs could be achieved.

description: The Barrett-Cavalcanti-Lal-Maroney (BCLM) argument stands as the most effective means of demonstrating the reality of the quantum state. Its advantages include being derived from very few assumptions, and a robustness to experimental error. Finding the best way to implement the argument experimentally is an open problem, however, and involves cleverly choosing sets of states and measurements. I show that techniques from convex optimisation theory can be leveraged to numerically search for these sets, which then form a recipe for experiments that allow for the strongest statements about the ontology of the wavefunction to be made. The optimisation approach presented is versatile, efficient and can take account of the finite errors present in any real experiment. I find significantly improved low-cardinality sets which are guaranteed partially optimal for a BCLM test in low Hilbert space dimension. I further show that mixed states can be more optimal than pure states.

description: The transformer-based semantic segmentation approaches, which divide the image into different regions by sliding windows and model the relation inside each window, have achieved outstanding success. However, since the relation modeling between windows was not the primary emphasis of previous work, it was not fully utilized. To address this issue, we propose a Graph-Segmenter, including a Graph Transformer and a Boundary-aware Attention module, which is an effective network for simultaneously modeling the more profound relation between windows in a global view and various pixels inside each window as a local one, and for substantial low-cost boundary adjustment. Specifically, we treat every window and pixel inside the window as nodes to construct graphs for both views and devise the Graph Transformer. The introduced boundary-aware attention module optimizes the edge information of the target objects by modeling the relationship between the pixel on the object's edge. Extensive experiments on three widely used semantic segmentation datasets (Cityscapes, ADE-20k and PASCAL Context) demonstrate that our proposed network, a Graph Transformer with Boundary-aware Attention, can achieve state-of-the-art segmentation performance.

description: Anaemia and immunosuppresion have been shown to be a cardinal feature in African trypanosomosis. In this study, we have evaluated and compared the capacity of two registered veterinary trypanocides Novidium® (homidium chloride) and Berenil® (diminazene aceturate) to reduce haematological and biochemical lesions in rats experimentally infected with T. brucei. Packed cell volume (PCV), lymphocyte and eosinophil values in infected negative control group were significantly different and lower compared to positive control group as well as infected animals treated with homidium chloride and diminazene aceturate (P<0.05). Also the white blood cell (WBC) and neutrophil counts in the negative control group were lower and significantly different from the other groups indicating evidence of infection-induced immunosuppresion. Haematological indices in infected rats treated with homidium chloride and diminazene aceturate were higher (P<0.05) than obtained in infected negative control group and significantly different from positive control (P<0.05). Total protein and albumin concentrations in infected negative control group were higher and significantly different from control and treated animals (P<0.05). In contrast, significantly lower values were obtained for albumin concentrations in treated animals compared to both negative and positive control groups (P<0.05). Results suggest that drugs administered have capacity to improved blood components as well as reverse immunosuppressive action of infecting trypanosomes.

description: Citrinin is a nephrotoxic mycotoxin from the group of polyketides synthesized by moulds of
 genera Penicillium (P. citrinum, P. viridicatum, P. expansum, P. notatum), Aspergillus and
 Monascus. Citrinin can be found in cereals with small grains (wheat, oats, barley, rye, rice) and
 large grains (corn), oilseeds (peanuts), fruits, vegetables, fruit juices, spices and in dairy
 products since cereals are basis for the feed. Commonly, citrinin is formed after harvest, under
 poor storage conditions, i.e. in silos.
 In 2012, the European Food Safety Authority published a Scientific Opinion on the risks for
 public and animal health related to the presence of citrinin in food and feed. Since data on the
 occurrence of citrinin in food and feed are insufficient, in recent years, EFSA in its calls for
 continuous data collection on the occurrence of certain contaminants has include the collection
 of additional data on citrinin.
 Therefore, the Croatian Food Agency (present the Croatian Agency for Agriculture and Food)
 in 2017, at the suggestion of its Scientific Panel for Chemical Hazards, was launched a threeyear
 study of the occurrence of citrinin in cereals (wheat, barley, corn) in four Croatian counties
 (Brod-Posavina, Osijek-Baranja, Koprivnica-Križevci and Međimurje). Results of the study
 were used for preparation of this scientific report. Statistical analysis of data was performed by
 use Statistics 13.3. software package.
 The results of a three-year study conducted by the Croatian Agency for Agriculture and Food
 show very high percentage of samples in which the concentration of citrinin was below the limit
 of quantification (LOQ), that only 5% of the samples were above the LOQ in concentration from
 8.0 μg/kg to 132 μg/kg.
 Comparison the results between examined years (2017, 2018 and 2019) showed that there is
 a statistically significant difference in distribution of data at the determined citrinin
 concentration, (p = 0.0174). Furthermore, the Kruskal – Wallis ANOVA test showed that there
 is no statistically significant difference in the distribution of citrinin concentration data between
 different types of cereals (p = 0.4953), and there is no statistically significant difference
 between the distribution of data by counties (p = 0.659).
 Given the insufficient number of data on the occurrence and toxicity of citrinin both in the
 Republic of Croatia and in Europe, it is necessary to conduct continuous collection of data on
 occurrence in order to define the toxicological limit and maximum levels for different types of
 products.

description: We consider the adiabatic limit of Hadamard states for free quantum Klein-Gordon fields, when the background metric and the field mass are slowly varied from their initial to final values. If the Klein-Gordon field stays massive, we prove that the adiabatic limit of the initial vacuum state is the (final) vacuum state, by extending to the symplectic framework the adiabatic theorem of Avron-Seiler-Yaffe. In cases when only the field mass is varied, using a abstract version of the mode decomposition method we can also consider the case when the initial or final mass vanishes, and the initial state is either a thermal state or a more general Hadamard state.

description: Background: Since the beginning of the COVID-19 pandemic and development of new vaccines, the issue of post-vaccination exacerbation or manifestation of demyelinating central nervous system (CNS) disorders has gained increasing attention. Case presentation: We present a case of a 68-year-old woman previously diagnosed with multiple sclerosis (MS) since the 1980s who suffered a rapidly progressive severe sensorimotor paraparesis with loss of bladder and bowel control due to an acute longitudinal extensive transverse myelitis (LETM) after immunization with the mRNA Pfizer–BioNTech COVID-19 vaccine. Detection of Aquaporin-4-antibodies (AQP4) in both serum and CSF led to diagnosis of AQP4-antibody positive neuromyelitis optica spectrum disorder (NMOSD). Treatment with intravenous corticosteroids and plasmapheresis led to a slight improvement of the patient’s symptoms. Conclusions: Pathogenic mechanisms of post-vaccination occurrence of NMOSD are still unknown. However, cases like this should make aware of rare neurological disorders manifesting after vaccination and potentially contribute to improvement of management of vaccinating patients with inflammatory CNS disorders in the future. So far two cases of AQP4-antibody positive NMOSD have been reported in association with viral vector COVID-19 vaccines. To our knowledge, we report the first case of AQP4-antibody positive NMOSD after immunization with an mRNA COVID-19-vaccine.

description: This study investigates the factors that affect customer adoption of internet banking on Commercial Bank of Ethiopia Addis Ababa city branches. The variables were chosen based on findings from the previous literatures. A mixed research approach and explanatory design were adopted in carrying out this research. Secondary time series data were collected from E-payment department reports and performance reports of the bank. In addition, use internal portal's and links. Multiple linear regression equation was used to estimate the model using SPSS version 20 software. The results obtained from regression output indicated that among the studied variables, Perceived usefulness, ease of use, prior internet knowledge, intention to use and convenience were found to be statistically significant determinant of adoption of internet banking. On the other hand, perceived risks were statistically insignificant in affecting adoption of internet banking. The study suggests that focusing on these internet banking variables could further reduce the probability of default while customer adoption of internet banking

description: A lattice polytope $\mathcal{P}$ is called reflexive if its dual $\mathcal{P}^\vee$ is a lattice polytope. The property that $\mathcal{P}$ is unimodularly equivalent to $\mathcal{P}^\vee$ does not hold in general, and in fact there are few examples of such polytopes. In this note, we introduce a new reflexive simplex $Q_n$ which has this property. Additionally, we show that $δ$-polynomalial of $Q_n$ is the Eulerian polynomial and show the existence of a regular, flag, unimodular triangulation.

Impact of Working Capital Management on Profitability of Small and Medium Scale Enterprises (SMES) In Addis Ababa(The Case of Nifas-Silk-Lafto and Kirkos Sub Cities)
Creators: name: Woldu, Ephrem
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: Small and medium enterprises occupy a prominent position in the development agenda of many developing countries like Ethiopia. The number of SMEs in Ethiopia is steadily growing. But, much more important than their number is their current status, stage and pace of development. Despite the tremendous increase in number of SMEs, little research exists that examines working capital management of small and medium enterprises (SMEs) in developing countries, especially in Ethiopia. The purpose of the study is to identify the impact of working capital management on the performance of the SMEs in Nifas silk and Kirkos sub cities and to give recommendations based on the problems. In doing so both Primary and secondary data was collected from 30 SMEs in those Sub cities of the capital city; Addis Ababa. The primary data was collected through the use of questionnaires and secondary data was gathered from the financial statements of the enterprises. The population of the study includes all SME's operating within organization for women in self employment (WISE). Data analysis was done using descriptive statistics and quantitative methods (correlation and regression). The findings of the paper suggest that working capital is negatively affected by the time period required by the enterprises to receive their debts, pay their bills and collect cash. Beside that the financial leverage, size and current ratio of those SME's under study have impact on the availability of adequate working capital requirements. Key words: net operating profitability, small and medium enterprises, working capital management

description: For a general two-body bound state in quantum mechanics, both in the stable and decaying cases, we establish a way to extract its two-body wave function in momentum space from the scattering amplitude of the constituent two particles. For this purpose, we first show that the two-body wave function of the bound state corresponds to the residue of the off-shell scattering amplitude at the bound state pole. Then, we examine our scheme to extract the two-body wave function from the scattering amplitude in several schematic models. As a result, the two-body wave functions from the Lippmann--Schwinger equation coincides with that from the Schrödinger equation for an energy-independent interaction. Of special interest is that the two-body wave function from the scattering amplitude is automatically scaled; the norm of the two-body wave function, to which we refer as the compositeness, is unity for an energy-independent interaction, while the compositeness deviates from unity for an energy-dependent interaction, which can be interpreted to implement missing channel contributions. We also discuss general properties of the two-body wave function and compositeness for bound states in the schematic models.

description: Fractional diffusion and Fokker-Planck equations are widely used tools to describe anomalous diffusion in a large variety of complex systems. The equivalent formulations in terms of Caputo or Riemann-Liouville fractional derivatives can be derived as continuum limits of continuous time random walks and are associated with the Mittag-Leffler relaxation of Fourier modes, interpolating between a short-time stretched exponential and a long-time inverse power-law scaling. More recently, a number of other integro-differential operators have been proposed, including the Caputo-Fabrizio and Atangana-Baleanu forms. Moreover, the conformable derivative has been introduced. We here study the dynamics of the associated generalized Fokker-Planck equations from the perspective of the moments, the time averaged mean squared displacements, and the autocovariance functions. We also study generalized Langevin equations based on these generalized operators. The differences between the Fokker-Planck and Langevin equations with different integro-differential operators are discussed and compared with the dynamic behavior of established models of scaled Brownian motion and fractional Brownian motion. We demonstrate that the integro-differential operators with exponential and Mittag-Leffler kernels are not suitable to be introduced to Fokker-Planck and Langevin equations for the physically relevant diffusion scenarios discussed in our paper. The conformable and Caputo Langevin equations are unveiled to share similar properties with scaled and fractional Brownian motion, respectively.

description: Factories are complex systems, which are characterized by interlinked and overlapping life cycles of the constituent factory elements. Within this context, the heterogeneity of these life cycles results in life cycle complexity and corresponding conflicts and trade-offs that need to be addressed in decision situations during the planning and operation of factory systems. Also with respect to the transformation need towards environmental sustainability, there is a need for methods and tools for life cycle oriented factory planning and operation. This paper systematically reviews existing life cycle concepts of factory systems as well as frameworks, models and methods for the evaluation and engineering of factory life cycles. In order to respond to the above challenges, a general understanding about the factory life cycle, e.g. life cycle stages, related activities and interdependencies, is developed and action areas of life cycle engineering are discussed that could supplement factory planning. Following that, the paper presents an integrated, model-based evaluation and engineering framework of factory life cycles. © 2022 The Authors

A worst-case optimization approach to impulse perturbed stochastic control with application to financial risk management

description: This work presents the main ideas, methods and results of the theory of impulse perturbed stochastic control as an extension of the classic stochastic control theory. Apart from the introduction and the motivation of the basic concept, two stochastic optimization problems are the focus of the investigations. On the one hand we consider a differential game as analogue of the expected utility maximization problem in the situation with impulse perturbation, and on the other hand we study an appropriate version of a target problem. By dynamic optimization principles we characterize the associated value functions by systems of partial differential equations (PDEs). More precisely, we deal with variational inequalities whose single inequalities comprise constrained optimization problems, where the corresponding admissibility sets again are given by the seeked value functions. Using the concept of viscosity solutions as weak solutions of PDEs, we avoid strong regularity assumptions on the value functions. To use this concept as sufficient verification method, we additionally have to prove the uniqueness of the solutions of the PDEs. As a second major part of this work we apply the presented theory of impulse perturbed stochastic control in the field of financial risk management where extreme events have to be taken into account in order to control risks in a reasonable way. Such extreme scenarios are modelled by impulse controls and the financial decisions are made with respect to the worstcase scenario. In a first example we discuss portfolio problems as well as pricing problems on a capital market with crash risk. In particular, we consider the possibility of trading options and study their in uence on the investor's performance measured by the expected utility of terminal wealth. This brings up the question of crash-adjusted option prices and leads to the introduction of crash insurance. The second application concerns an insurance company which faces potentially large losses from extreme damages. We propose a dynamic model where the insurance company controls its risk process by reinsurance in form of proportional reinsurance and catastrophe reinsurance. Optimal reinsurance strategies are obtained by maximizing expected utility of the terminal surplus value and by minimizing the required capital reserves associated to the risk process.

description: The government of Ethiopia is promoting the leather manufacturing sector as a priority subsector and the sector has a huge potential to develop an economy. However; its performance is unsatisfactory due to external and internal problem that hinders its competitiveness in the international market. Thus, the aim of this study was to investigate the effect of determinants on export performance of domestic leather footwear export manufacturing firms in Ethiopia. Determinants of export performance such as product quality, capital, export knowledge, technological capability, global competition and export promotional support were analyzed based on the selected conceptual framework. A quantitative research approach was applied in order to achieve research objectives. The researcher used a purposive sampling technique to select four departments and 9 heads of respondents in each 14 domestic footwear manufacturing firms. A structured questionnaires were distributed to 126 respondents those who represent the firm and 108 were collected. The collected data was analyzed through statistical techniques such as descriptive statistics, correlations and multiple linear regressions using Statistical Package for Social Science (SPSS) version 20.The research finding clearly indicates that product quality, capital, export knowledge, technological capability and export promotional support have a positive significant effect with coefficient of 0.293, 0.237, 0.197, 0.114 and 0.092 on export performance of domestic leather footwear export manufacturing firms respectively. It means that a unit increase in each variable will result in an increase on export performance by the value of each coefficient of variables. Global competition has negative relationship with export performance. It means that a unit increase in global competition will result in a decrease in export performance. Based on the findings of the study, the study recommends that local exporting firms need a special support in finance, technology and promotion in order to be competent in the international market. Therefore, the government should introduce special incentive policies that encourage the export manufacturing industry in order to gain the expected foreign currency earnings and the overall economic development from the sector

description: In this article we explore the angular resolution limits attainable in small FDIRC designs taking advantage of the new highly pixelated detectors that are now available. Since the basic FDIRC design concept attains its particle separation performance mostly in the angular domain as measured by two-dimensional pixels, this paper relies primarily on a pixel-based analysis, with additional chromatic corrections using the time domain, requiring single photon timing resolution at a level of 100-200ps only. This approach differs from other modern DIRC design concepts such as TOP or TORCH detectors, whose separation performances rely more strongly on time-dependent analyses. We find excellent single photon resolution with a geometry where individual bars are coupled to a single plate, which is coupled in turn to a cylindrical lens focusing camera.

description: A new quantile regression concept, based on a directional version of Koenker and Bassett’s traditional single-output one, has been introduced in [Hallin, Paindaveine and ˇSiman, Annals of Statistics 2010, 635-703] for multiple-output regression problems. The polyhedral contours provided by the empirical counterpart of that concept, however, cannot adapt to nonlinear and/or heteroskedastic dependencies. This paper therefore introduces local constant and local linear versions of those contours, which both allow to asymptotically recover the conditional halfspace depth contours of the response. In the multiple-output context considered, the local linear construction actually is of a bilinear nature. Bahadur representation and asymptotic normality results are established. Illustrations are provided both on simulated and real data.

description: The research investigates the roles that think tanks in Ethiopia such as the Ethiopian Economics Association (EEA) and the Forum for Social Studies (FSS) are playing in influencing or contributing to policy-making process in Ethiopia. The general objective of the study is to identify the roles that think tanks play in Ethiopia, the relevance of their research to policy making and the challenges and opportunities they are encountering. The researcher has used qualitative research method and has employed purposive sampling technique. The data was collected using semi-structured questionnaire, in-depth key informant interview and review of documentation. The use of questionnaire was used to complement the interview. The data was analyzed using descriptive analysis method. The timeframe used for the study is since the establishment of the EEA and FSS. The findings of the study indicate that think tanks contribute widely to the policy making process, however, they are not achieving their full potential. There is still room to improve their influence and the relevance of the research topics they select. In terms of challenge, they are operating in a restrictive and disabling regulatory environment imposed by the Charities and Societies Proclamation, limited democratic space and diminishing financial resources. Their trajectory is therefore a downward type as staff morale is also affected. In order for think tanks to surmount the difficulties they are facing, the regulation needs to be adapted to encourage their performance, the democratic space needs to open up and the funding issue resolved through various fund raising mechanisms

description: Banking industry in Ethiopia has stiff competition thus banks need to consider various strategic options and programs in order to survive and thrive. One of strategy is Customer Relationship Marketing (CRM).This study was aimed to examine the effect of customer relationship marketing dimensions (trust, commitment, conflict handling, and communication) on customer loyalty of commercial banks in Ethiopia. A survey was conducted, collecting data through a questionnaire containing 30 items from sample of 384 conveniently selected bank customers. The statistical result revealed that three relationship marketing dimensions: trust, communication and conflict handling have positive and significant effect on customer loyalty. Whereas commitment has negative and but insignificance effect on customer loyalty. The relationship between relationship marketing and customer loyalty was found partially significant. Banks should focus on CRM so that they are expected to attracting new customers and more on retaining the existed ones with regard to relationship marketing to increase customer loyalty
title: Artificial Intelligence Applied to Facial Image Analysis and Feature Measurement

description: Beauty has always played an essential part in society, influencing both everyday human interactions and more significant aspects such as mate selection. The continued and expanding use of beauty products by women and, increasingly, men worldwide has prompted and motivated several companies to develop platforms that effectively integrate into the beauty and cosmetics sector. They attempt to improve the customer experience by combining data with personalisation. Global cosmetics spending is worth billions of dollars, and most of it is wasted on unsuitable or incompatible products. This enables artificial intelligence to alter the rules using computer vision and deep learning approaches, allowing customers to be completely satisfied. With the advanced feature extraction in deep learning, especially convolutional neural networks, automatic facial feature analysis from images for the sake of beauty and beautification has become an emerging subject of study. Scholars studying facial aesthetics have recently made breakthroughs in the areas of facial shape beautification and beauty prediction. In the cosmetics sector, a new line of recommendation system research has arisen. Users benefit from recommendation systems since these systems help them narrow down their options. This thesis has laid the groundwork for a recommendation system related to beautification purposes through hairstyle and eyelashes leveraging artificial intelligence techniques. One of the most potent descriptors for attribution of personality is facial attributes. Various types of facial attributes are extracted in this thesis, including geometrical, automatic and hand-crafted features. The extracted attributes provide rich information for the recommendation system to produce the final outcome. The coexistence of external effects on the faces, like makeup or retouching, could disguise facial features. This might result in degradation in the performance of facial feature extraction and subsequently in the recommendation system. Thus, three methods are further developed to detect the faces wearing the makeup before passing the images into the recommendation system. This would help to provide more reliable and accurate feature extraction and suggest more suitable recommendation results. This thesis also presents a method for segmenting the facial region with the goal of extending the developed recommendation system by incorporating a synthesised hairstyle virtually on the facial region, thereby harnessing the recommended hairstyle generated by our developed system. Hence, the work presented in this thesis shows the benefits of implementing computational intelligence methods in the beauty and cosmetics sector. It also demonstrates that computational intelligence techniques have redefined the notion of beauty and how the consumer communicates with these emerging intelligent facilities that bring solutions to our fingertips.

description: Das 166 kD schwere Protein Nalp1 gehört zur Familie der Nod-ähnlichen Rezeptoren (NLR), die eine wichtige Rolle im angeborenen Immunsystem spielen. Als intrazelluläre Rezeptoren erkennen sie Pathogene, die bereits in die Zelle eingedrungen sind. Nach der Aktivierung durch Pathogen-assoziierte molekulare Strukturen setzen die Nod-ähnlichen Rezeptoren über einen bislang wenig erklärten Mechanismus Entzündungsreaktionen in Gang. Im Rahmen dieser Arbeit konnte die Kristallstruktur der LRR-Domäne von humanem Nalp1 bis zu einer Auflösung von 1.65 Å aufgeklärt werden. Diese Kristallstruktur liefert die erste dreidimensionale Beschreibung der regulatorischen Domäne eines Nod-ähnlichen Rezeptors. Die Struktur zeigt, dass die LRR-Domäne von Nalp1 aus sechs vollständigen Leucin-reichen Wiederholungen besteht, die aus insgesamt sieben α-Helices und sieben β-Strängen geformt werden. Durch den geometrischen Vergleich mit LRR-Domänen anderer Proteine konnte die LRR-Domäne von Nalp1 der RI-ähnlichen Unterfamilie von LRR Proteinen zugeordnet werden. Unter Verwendung unterschiedlicher biophysikalischer Methoden wurde untersucht, ob Muramyldipeptid (MDP) an die isolierte LRR-Domäne von humanem Nalp1 bindet. In der Literatur ist MDP als Pathogen-assoziierte molekulare Struktur beschrieben worden, die in vitro den Rezeptor aktiviert. Ligandenbindungsstudien über Isothermale Titrationskaloriemetrie, Fern-UV CD Spektroskopie sowie Fluoreszenz- und Polarisationsspektroskopie zeigten keine Interaktion zwischen MDP und der LRR-Domäne von humanem Nalp1. Aus den Ergebnissen dieser Arbeit kann für den Aktivierungsmechanismus des humanen Nalp1 gefolgert werden, dass die LRR-Domäne des Rezeptors alleine nicht ausreichend ist für die Bindung des Liganden.
