description: Scholars have paid increasing attention to how questions of multi-level governance have become politicized in the domestic political arena. Issues surrounding democratic government itself have received surprisingly little attention in this debate. In this article, we ask how political parties politicize the principles of liberal democracy within advanced democracies. We expect that challenger parties are most likely to question existing principles. The targets of their criticism, however, should vary according to their ideological origins. Conducting automated quantitative text analysis of Swiss, German and Austrian party press releases between 2006 and 2018 using a multidimensional dictionary of liberal democracy, we confirm that left-libertarian and populist radical right parties are the main challengers of the democratic status quo. The foundation of criticism, however, differs fundamentally. While left-libertarians focus on principles that strengthen individual autonomy in politics, populist radical right parties demand more forms of participation and fewer constraints by liberal elements of democracy.

description: Cilia and flagella exhibit regular bending waves that perform mechanical work on the surrounding fluid, to propel cellular swimmers and pump fluids inside organisms. Here, we quantify a force-velocity relationship of the beating flagellum, by exposing flagellated \emph{Chlamydomonas} cells to controlled microfluidic flows. A simple theory of flagellar limit-cycle oscillations, calibrated by measurements in the absence of flow, reproduces this relationship quantitatively. We derive a link between the chemo-mechanical efficiency of the flagellar beat and its ability to synchronize to oscillatory flows.

description: Mit Hilfe von im Jahre 1997 aufgezeichneten Daten des H1-Experiments wurde der doppelt differentielle Wirkungsquerschnitt von QED-Compton-Streuung beiHERA gemessen. Die Messung wurde in Intervallen der kinematischen Variablen xl und Q2l im Bereich 1.8 · 10-5 < xl < 1.8 · 10-3 und 2 GeV2 < Q2l < 86 GeV2durchgeführt. Die Ergebnisse werden benutzt, um Informationen über die Protonstrukturfunktion F2 im kinematischen Bereich von kleinen Virtualitäten desausgetauschten Photons Q2h bis zu 0.05 GeV2 und in einem breiten Bereich der Bjorkenschen Variablen xh zwischen ca. 10-4 und 0.5 zu gewinnen, also in einemnicht in inklusiver ep-Streuung bei HERA zugänglichen kinematischen Bereich. Außerdem wurde die Messung mit theoretischen Berechnungen in der kollinearenApproximation verglichen, in der das ausgetauschte Photon als Parton im Proton betrachtet wird. Es wurde gefunden, dass dieser Ansatz im Bereich inelastischerQED-Compton-Streuung zu signifikanten Diskrepanzen zwischen den vorhergesagten und den gemessenen Werten des Wirkungsquerschnittes führt.
description: The double differential cross section of QED Compton scattering at HERA is measured using data collected in 1997 by the H1 experiment. The measurement iscarried out in bins of the kinematic variables xl and Q2l in the range 1.8 · 10-5 < xl < 1.8 · 10-3 and 2 GeV2 < Q2l < 86 GeV2. The results are used to gaininformation on the proton structure function F2 in the kinematic region of small virtualities of the exchanged photon Q2h down to 0.05 GeV2 and in a wide range ofthe Bjorken variable xh between approximately 10-4 and 0.5, a region which is not accessible in inclusive ep scattering at HERA. The measurement is alsoconfronted to theoretical calculations performed in the collinear approximation, in which the exchanged photon is treated as a parton of the proton. It is found thatthis approach leads to significant discrepancies between the predicted and the measured cross section values in the domain of inelastic QED Compton scattering.

description: Perturbative matching relates the parton quasi-distributions, defined by Euclidean correlators at finite hadron momenta, to the light-cone distributions which are accessible in experiments. Previous matching calculations have exclusively focused on twist-2 distributions. In this work, we address, for the first time, the one-loop matching for the twist-3 parton distribution function $g_T(x)$. The results have been obtained using three different infrared regulators, while dimensional regularization has been adopted to deal with the ultraviolet divergences. We present the renormalized expressions of the matching coefficient for $g_{T}(x)$ in the $\overline{\rm MS}$ and modified $\overline{\rm MS}$ schemes. We also discuss the role played by a zero-mode contribution. Our results have already been used for the extraction of $g_T(x)$ from lattice QCD calculations.

description: In this paper, we consider the existence problem of rank one and two stable Ulrich bundles on imprimitive Fano 3-folds obtained by blowing-up one of $\mathbb{P}^{3}$, $Q$ (smooth quadric in $\mathbb{P}^{4}$), $V_{3}$ (smooth cubic in $\mathbb{P}^{4}$) or $V_{4}$ (complete intersection of two quadrics in $\mathbb{P}^{5}$) along a smooth irreducible curve. We prove that the only class which admits Ulrich line bundles is the one obtained by blowing up a genus 3, degree 6 curve in $\mathbb{P}^{3}$. Also, we prove that there exist stable rank two Ulrich bundles with $c_{1}=3H$ on a generic member of this deformation class.

Brexit and the ties that bind: how global finance shapes city-level growth models

description: This paper contributes to the Growth Model (GM) research program in comparative and international political economy by analyzing the impact of Brexit on London and other financial centers within the European Union (EU). Our key contribution is to demonstrate that for many countries, national growth models are really city-level growth models, and that this is directly observable in the relationship between GMs and their international financial centers. Such city-level GMs are possible precisely because they do not depend on, nor are they deeply integrated into, the rest of their national economy. To explain these observations, we draw upon insights from economic sociology and argue that ‘place-specific social capital’ and professional ‘linked ecologies’ make such internationally oriented city-level GMs highly robust to external shocks – even one as big as Brexit. Empirically, we develop this argument using financial firm-level data to observe the post-Brexit movement of assets, loans, and jobs in London, Dublin, Amsterdam, Paris and Frankfurt. We conclude with some observations on what a city-level GM perspective means for the study of comparative and international political economy.

description: An efficient finite-difference time-domain (FDTD) algorithm is built to solve the transverse electric 2D Maxwell's equations with inhomogeneous dielectric media where the electric fields are discontinuous across the dielectric interface. The new algorithm is derived based upon the integral version of the Maxwell's equations as well as the relationship between the electric fields across the interface. It is an improvement over the contour-path effective-permittivity algorithm by including some extra terms in the formulas. The scheme is validated in solving the scattering of a dielectric cylinder with exact solution from Mie theory and is then compared with the above contour-path method, the usual staircase and the volume-average method. The numerical results demonstrate that the new algorithm has achieved significant improvement in accuracy over the other methods. Furthermore, the algorithm has a simple structure and can be merged into any existing FDTD software package very easily.

An Assessment of Urban Water Supply and Sanitation: the Case of Ambo Town, Oromia Region
Creators: name: Deyessa, Chala
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: The effort of this research is to access the status of household drinking water supply and sanitation services in Ambo town. The major factors attributed to lower accessibility are shortage of water supply, high cost of piped water connection, length of process during connection and frequent interruption. The town has no sewerage system; no adequate and safe waste disposal sites. Further the municipality has no waste collection and disposal trucks. As result liquid wastes are released to rivers, ditches and on open spaces. These acts have seriously contributed to health, socioeconomic and environmental pollution. Community participation in water supply and sanitation is inadequate due to the weakness of offices or authorities particularly municipality in coordinating and promoting active community participation

description: The theory of composite bosons (cobosons) made of two fermions [Phys. Rev. A 71, 034306 (2005), Phys. Rev. Lett. 109, 260403 (2012)] converges to ordinary structureless bosons in the limit of infinitely strong entanglement between the fermionic constituents. For finite entanglement, the annihilation operator $\hat c$ of a composite boson couples the $N$-coboson Fock-state not only to the $(N-1)$-coboson state -- as for ordinary bosons --, but also to a component which is orthogonal to the Fock-state ladder of cobosons. Coupling with states orthogonal to the Fock ladder arises also in dynamical processes of cobosons. Here, with a Gedanken-experiment involving both mode-splitting and collective Hong-Ou-Mandel-like interference, we derive the characteristic physical signature of the states orthogonal to the Fock ladder generated in the splitting process. This allows to extract microscopic properties of many-fermion-wave functions from the collective coboson behavior. We show that consecutive beam-splitter dynamics increases the deviation from the ideal bosonic behavior pattern, which opens up a rigorous approach to the falsification of coboson theory.

description: In an earlier paper, the second author resolved a question of McDuff by constructing a non-Hamiltonian symplectic circle action on a closed, connected six-dimensional symplectic manifold with exactly 32 fixed points. In this paper, we improve on this example by reducing the number of fixed points. More concretely, we construct a non-Hamiltonian symplectic circle action on a closed, connected six-dimensional symplectic manifold with exactly $2k$ fixed points for any $k \geq 5$.

description: Vector-like quarks are featured by a wealth of beyond the Standard Model theories and are consequently an important goal of many LHC searches for new physics. Those searches, as well as most related phenomenological studies, however rely on predictions evaluated at the leading-order accuracy in QCD and consider well-defined simplified benchmark scenarios. Adopting an effective bottom-up approach, we compute next-to-leading-order predictions for vector-like-quark pair-production and single production in association with jets, with a weak or with a Higgs boson in a general new physics setup. We additionally compute vector-like-quark contributions to the production of a pair of Standard Model bosons at the same level of accuracy. For all processes under consideration, we focus both on total cross sections and on differential distributions, most these calculations being performed for the first time in our field. As a result, our work paves the way to precise extraction of experimental limits on vector-like quarks thanks to an accurate control of the shapes of the relevant observables and emphasize the extra handles that could be provided by novel vector-like-quark probes never envisaged so far

description: A single photon source with high repeatability and low uncertainties is the key element for few-photon metrology based on photon numbers. While low photon number fluctuations and high repeatability are important figures for qualification as a standard light source, these characteristics are limited in single photon emitters by some malicious phenomena like blinking or internal relaxations to varying degrees in different materials. This study seeks to characterize photon number fluctuations and repeatability for radiometry applications at room temperature. For generality in this study, we collected photon statistics data with various single photon emitters of $g^{(2)}(0) < 1$ at low excitation power and room temperature in three material platforms: silicon vacancy in diamond, defects in GaN, and vacancy in hBN. We found common factors related with the relaxation times of the internal states that indirectly affect photon number stability. We observed a high stability of photon number with defects in GaN due to faster relaxations compared with vacancies in hBN, which on the other hand produced high rates ($> 10^6$) of photons per second. Finally, we demonstrate repeatable radiant flux measurements of a bright hBN single photon emitter for a wide radiant flux range from a few tens of femtowatts to one picowatt.

Publisher: name: arXiv
Year: 2016
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: A new formalism is introduced to treat problems in quantum field theory, using coherent functional expansions rather than path integrals. The basic results and identities of this approach are developed. In the case of a Bose gas with point-contact interactions, this leads to a soluble functional equation in the weak interaction limit, where the perturbing term is part of the kinetic energy. This approach has the potential to prevent the Dyson problem of divergence in perturbation theory.

description: In recent years, some studies have drawn attention to the lack of large-angle correlations in the observed cosmic microwave background (CMB) temperature anisotropies with respect to that predicted within the standard $Λ$CDM model. Lately, it has been argued that such a lack of correlations could be explained in the framework of the so-called $R_h=ct$ model without inflation. The aim of this work is to study whether there is a mechanism to generate, through a quantum field theory, the primordial power spectrum presented by these authors. Specifically, we consider two different scenarios: first, we assume a scalar field dominating the early Universe in the $R_h=ct$ cosmological model, and second, we deal with the possibility of adding an early inflationary phase to the mentioned model. During the analysis of the consistency between the predicted and observed amplitudes of the CMB temperature anisotropies in both scenarios, we run into deep issues which indicate that it is not clear how to characterize the primordial quantum perturbations within the $R_h=ct$ model.

description: Within low-nutrient tropical oceans, islands and atolls with higher primary production support higher fish biomass and reef organism abundance. External energy subsidies can be delivered onto reefs via a range of physical mechanisms. However, the influence of spatial variation in primary production on reef fish growth and condition is largely unknown. It is not yet clear how energy subsidies interact with reef depth and slope. Here we test the hypothesis that with increased proximity to deep-water oceanic nutrient sources, or at sites with shallower reef slopes, parameters of fish growth and condition will be higher. Contrary to expectations, we found no association between fish growth rate and sites with higher mean chlorophyll-a values. There were no differences in fish δ15N or δ13C values between depths. The relationship between fish condition and primary production was influenced by depth, driven by increased fish condition at shallow depths within a primary production ‘hotspot’ site. Carbon δ13C was depleted with increasing primary production, and interacted with reef slope. Our results indicate that variable primary production did not influence growth rates in planktivorous Chromis fieldi within 10–17.5 m depth, but show site-specific variation in reef physical characteristics influencing fish carbon isotopic composition.

description: In this paper we introduce a method to overcome one of the main challenges of person re-identification in multi-camera networks, namely cross-view appearance changes. The proposed solution addresses the extreme variability of person appearance in different camera views by exploiting multiple feature representations. For each feature, Kernel Canonical Correlation Analysis (KCCA) with different kernels is exploited to learn several projection spaces in which the appearance correlation between samples of the same person observed from different cameras is maximized. An iterative logistic regression is finally used to select and weigh the contributions of each feature projections and perform the matching between the two views. Experimental evaluation shows that the proposed solution obtains comparable performance on VIPeR and PRID 450s datasets and improves on PRID and CUHK01 datasets with respect to the state of the art.

description: In dieser Arbeit wird die doppelt-diffusive Konvektion anhand von theoretischen Überlegungen, Experimenten mit einem Tensid/Glyzerin System und Computersimulationen der Navier-Stokes Gleichungen untersucht. Die Untersuchungen befassen sich mit der Wellenlänge und Form der dabei auftretenden Strukturen. Die bisherigen theoretischen Modelle der Wellenlänge basieren auf den Konzentrationsgradienten des Systems unter Vernachlässigung einer Zeitabhängigkeit. Dieses Modell wird durch eine Berücksichtigung der Zeitabhängigkeit erweitert, so daß der bisherige Parameter des Konzentrationsgradienten durch die anfängliche Konzentration ersetzt wird. Weiterhin wird die Wachstumszeit als eine neue Meßgröße eingeführt. Für ein stufenförmiges Konzentrationsprofil werden quantitative Voraussagen zum Skalenverhalten der Wachstumszeit und der Wellenlänge getroffen.Diese Voraussagen können anhand von Computersimulationen bestätigt werden. Darüber hinaus werden Simulationen mit weiteren Anfangsbedingungen durchgeführt. Hierbei ergeben sich Veränderungen im Skalenverhalten, die theoretisch begründbar sind.Die Wellenlänge und die Wachstumszeit werden weiterhin in Experimenten mit einem Tensid/Glyzerin System untersucht. Diese Messungen zeigen eine quantitative Übereinstimmung mit den Computersimulationen.Die Form der Strukturen wird anhand von Experimenten und Computersimulationen untersucht. Basierend auf den bisherigen Arbeiten werden Simulationen mit einer externen Scherströmung durchgeführt. Hierbei zeigt sich ein Übergang von einer waben- zu einer streifenförmigen Struktur. Dieses Phänomen kann in weiteren Simulationen ohne externe Einflüsse nur durch die Form der Anfangsbedingung erzielt werden. Dabei treten erstmalig verschiedene Strukturen in nur einem System auf. Darüber hinaus werden in diesem System neue Mechanismen der Strukturentstehung beschrieben.Diese Strukturen und ihre Entstehungsmechanismen können experimentell in allen Punkten bestätigt werden. Somit eignet sich dieses System insbesondere als universelles Demonstrationsexperiment der doppelt-diffusiven Konvektion.
An Assessment of Service Delivery Performance in the Aftermath of Business Process Reengineering Implementation the Case of Ethiopian Civil Aviation Authority
Creators: name: Haile, Habtamu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2010

description: Currently there is a widely shared understanding that Business Process Reengineering has transformed the service delivery performance of many government institutions at federal, regional as well as local levels. Processes which had been taking months or years with high cost have been made to be performed in hours and or days with lowest possible cost. The court system at federal and regional levels, municipal services at kebeles' in Addis Ababa city administration and many other institutions can be mentioned as an example. This study was conducted to assess the service delivery performance of Ethiopian Civil Aviation Authority in the aftermath of implementing BPR. The study is initiated due to the prevailing mass dissatisfactions and instability in the organization since the time of the implementation of BPR. Accordingly the study has examined the attitudes of ECAA employees and customers' evaluation about the changes brought by BPR implementation. To this purpose a comparative employee attitude analysis was made on the service delivery performance of the organization between the pre and post BPR implementation periods using pearsons' correlation and T-test as statistical tools. Furthermore, clients of the Authority evaluated its' service delivery performance using ten quality dimensions and their scores are analyzed based on the service quality model of parsmanma. The opinions of the management members have also been included in the assessment using semi structured interview. The finding has revealed that the Authority has not attained the required transformation from both the opinions of its employees and clients. The aggregate attitude Based on the findings of the study the researcher recommends the authority to revisit the BPR study and to work on improving the attitudes of its employees. A concerted effort has to be made to maintain its skilled human power. Especially the management of Ethiopian Civil Aviation Authority has to learn from the consequences of false promise to carry out a specified task and avoid such promises at any cost. Moreover, proper planning and timing is the key for successful implementation of programs and attainment of organizational objectives. Therefore, it is the time for Ethiopian Civil Aviation Authority to wake up and commit itself on investigating why the organization failed to attain the required transformation and find out solutions for further intervention
Clustering of variables for enhanced interpretability of predictive models

Year: 2020
Subjects: subject: Applications (stat.AP)
subject: FOS: Computer and information sciences

description: A new strategy is proposed for building easy to interpret predictive models in the context of a high-dimensional dataset, with a large number of highly correlated explanatory variables. The strategy is based on a first step of variables clustering using the CLustering of Variables around Latent Variables (CLV) method. The exploration of the hierarchical clustering dendrogram is undertaken in order to sequentially select the explanatory variables in a group-wise fashion. For model setting implementation, the dendrogram is used as the base-learner in an L2-boosting procedure. The proposed approach, named lmCLV, is illustrated on the basis of a toy-simulated example when the clusters and predictive equation are already known, and on a real case study dealing with the authentication of orange juices based on 1H-NMR spectroscopic analysis. In both illustrative examples, this procedure was shown to have similar predictive efficiency to other methods, with additional interpretability capacity. It is available in the R package ClustVarLV.

description: We report on new results of a search for two-photon interaction with axionlike particles (ALPs). The experiment was carried out at a synchrotron radiation facility using a "light shining through a wall (LSW)" technique. For this purpose, we have developed a novel pulsed-magnet system, composed of multiple racetrack-magnets and a transportable power supply. It produces fields of about 10 T over 0.8 m with a high repetition rate of 0.2 Hz and yields a new method of probing vacuum with high intensity fields. The data obtained with a total of 27,676 pulses provide a limit on the ALP-two-photon coupling constant that is more stringent by a factor of 5.2 compared to a previous x-ray LSW limit for the ALP mass below 0.1 eV.

description: This paper shows how the gender composition of executive government impacts national responses to crises through the case study of the COVID-19 pandemic. Building on descriptive accounts of women’s underrepresentation in COVID-19 decision-making I consider the causes and consequences of their (non)presence. Using data from the UN COVID-19 Global Gender Response Tracker, I find that: (i) across 62 countries, women average 25 per cent of members of government taskforces responding to the crisis and are siloed into advisory as opposed to decision-making positions; and, (ii) Women leaders shape who is present in policy-making, and policy outcomes. Women-led countries, although limited in number, have higher proportions of women on taskforces, especially decision-making ones. A country being woman-led has a large, although non-significant, positive effect on whether a policy response is gender-sensitive, whilst a higher proportion of women on all taskforces combined has a significant, yet small, positive effect.

Year: 2019

description: Companies in order to create the right packaging for their products, they must understand their sales performance and also the role and the effect of packaging as a variable that can influence the sales of the product. Therefore, by understanding, what factors influence the sales performance and what packaging elements are most important that will help companies making the right decisions about product packaging. The research identified the dependent variable of the study that is the sales performance and some independent variables like packaging color, packaging material, printed information and innovation. The research mainly focuses on coffee processing company TO.MO.CA PLC which is one of the pioneers in production of coffee. There are 10 branches in Addis Ababa but by using convenience sampling, 5 branches were selected. The research data was collected through 385 structured questionnaires and SPSS V 25.0 was used to analyze the data collected and to test the hypotheses put forward. The result also showed packaging color, packaging material, product information and innovation all have a strong and positive relation with the sales performance as they were hypothesized. Based on the result of the study it is recommended that coffee companies should pay much attention specifically for product information and innovation packaging

description: Within low-nutrient tropical oceans, islands and atolls with higher primary production support higher fish biomass and reef organism abundance. External energy subsidies can be delivered onto reefs via a range of physical mechanisms. However, the influence of spatial variation in primary production on reef fish growth and condition is largely unknown. It is not yet clear how energy subsidies interact with reef depth and slope. Here we test the hypothesis that with increased proximity to deep-water oceanic nutrient sources, or at sites with shallower reef slopes, parameters of fish growth and condition will be higher. Contrary to expectations, we found no association between fish growth rate and sites with higher mean chlorophyll-a values. There were no differences in fish δ15N or δ13C values between depths. The relationship between fish condition and primary production was influenced by depth, driven by increased fish condition at shallow depths within a primary production ‘hotspot’ site. Carbon δ13C was depleted with increasing primary production, and interacted with reef slope. Our results indicate that variable primary production did not influence growth rates in planktivorous Chromis fieldi within 10–17.5 m depth, but show site-specific variation in reef physical characteristics influencing fish carbon isotopic composition.

description: Low frequency high precision laser interferometry is subject to excess laser-frequency-noise coupling via arm-length differences which is commonly mitigated by locking the frequency to a stable reference system. This approach is crucial to achieve picometer level sensitivities in the 0.1 mHz to 1 Hz regime, where laser frequency noise is usually high and couples into the measurement phase via arm-length mismatches in the interferometers. Here we describe the results achieved by frequency stabilising an external cavity diode laser to a quasi-monolithic unequal arm-length Mach-Zehnder interferometer read out at mid-fringe via balanced detection. We find this stabilization scheme to be an elegant solution combining a minimal number of optical components, no additional laser modulations and relatively low frequency noise levels. The Mach-Zehnder interferometer has been designed and constructed to minimize the influence of thermal couplings and to reduce undesired stray light using the optical simulation tool ifocad. We achieve frequency-noise levels below 100 Hz/$\sqrt{\textrm{Hz}}$ at 1 Hz and are able to demonstrate the LISA frequency prestabilization requirement of 300 Hz/$\sqrt{\textrm{Hz}}$ down to frequencies of 100 mHz by beating the stabilized laser with an iodine-locked reference.

description: Current advancements in battery technologies require electrodes to combine high-performance active material such as Silicon (Si) with two-dimensional materials such as transition metal carbides (MXenes) for prolonged cycle stability and enhanced electrochemical performance. More so, it is the interface between these materials, which is the nexus for their applicatory success. Herein, the interface strength variations between amorphous Si and Ti3C2Tx MXene are determined as the MXene surface functional groups (Tx) are changed using first principle calculations. Si is interfaced with three Ti3C2 MXene substrates having surface -OH, -OH and -O mixed, and -F functional groups. Density functional theory (DFT) results reveal that completely hydroxylated Ti3C2 has the highest interface strength of 0.6 J/m2 with amorphous Si. This interface strength value drops as the proportion of surface -O and -F groups increases. Additional analysis of electron redistribution and charge separation across the interface is provided for a complete understanding of underlying physico-chemical factors affecting the surface chemistry and resultant interface strength values. The presented comprehensive analysis of the interface aims to develop sophisticated MXene based electrodes by their targeted surface engineering.

description: We apply some of the latest techniques from machine-learning to the arithmetic of hyperelliptic curves. More precisely we show that, with impressive accuracy and confidence (between 99 and 100 percent precision), and in very short time (matter of seconds on an ordinary laptop), a Bayesian classifier can distinguish between Sato-Tate groups given a small number of Euler factors for the L-function. Our observations are in keeping with the Sato-Tate conjecture for curves of low genus. For elliptic curves, this amounts to distinguishing generic curves (with Sato-Tate group SU(2)) from those with complex multiplication. In genus 2, a principal component analysis is observed to separate the generic Sato-Tate group USp(4) from the non-generic groups. Furthermore in this case, for which there are many more non-generic possibilities than in the case of elliptic curves, we demonstrate an accurate characterisation of several Sato-Tate groups with the same identity component. Throughout, our observations are verified using known results from the literature and the data available in the LMFDB. The results in this paper suggest that a machine can be trained to learn the Sato-Tate distributions and may be able to classify curves much more efficiently than the methods available in the literature.

description: Das HERA-B Experiment am Deutschen Elektronen-Synchrotron (DESY) in Hamburg wurde aufgebaut, um die CP-Verletzung im System der neutralen B-Mesonen zu untersuchen. Für diese und weitere Messungen zur Physik schwerer Quarks ist es notwendig, Ereignisse mit Myonen im Endzustand effizient zu selektieren. Der Myon-Pretrigger definiert Startpunkte für Myonspuren für die nachfolgenden Triggerstufen. Im Rahmen dieser Arbeit wird ein Simulationsprogramm entwickelt, das die Funktion des Myon-Pretrigger-Systems auf dem Niveau von Bitoperationen beschreibt. Unter Verwendung dieses Programmes werden die Effizienz, Akzeptanz und die Latenzzeit als wichtige Kenngrößen des Myon-Pretrigger-Systems bestimmt. Zudem werden Ergebnisse einer Untersuchung zu einem Multiplizitäts-Veto-System präsentiert.
description: The HERA-B experiment was built up at the Deutsches Elektronen-Synchrotron (DESY) in Hamburg to study CP violation in the neutral B meson system. For this and other measurements in the field of heavy quark physics an efficient selection of events with final state muons is needed. The muon pretrigger defines starting points for muon track candidates for the higher level trigger systems. Within the scope of this thesis a simulation program is developed that describes the operation of the muon pretrigger system on the bit level. Using this program the efficiency, acceptance and latency of the muon pretrigger system are determined. In addition results of studies on a multiplicity veto system are presented.

description: The ratios of off-diagonal and diagonal susceptibilities of conserved charges are studied using a hadron resonance gas (HRG) model with an emphasis towards providing a proper baseline for comparison to the corresponding future experimental measurements. We have studied the effect of kinematic acceptances, transverse momentum ($p_T$) and pseudorapidity ($η$), and different charged states on the ratios of the calculated susceptibilities. We find that the effect of $p_T$ and $η$ acceptance on the ratio of the susceptibilities are small relative to their dependence on the beam energy or the charged states of the used particles. We also present a HRG based calculation for various combinations of cumulant ratios of protons and pions, recently proposed as robust observables (with no theoretical uncertainties) for critical point search in the experiments. These results which increase as a function of collision energy will provide a better baseline for non-critical point physics compared to Poisson expectation.
