description: We review several aspects of flavour-diagonal CP violation, focussing on the role played by the electric dipole moments (EDMs) of leptons, nucleons, atoms and molecules, which consitute the source of several stringent constraints on new CP-violating physics. We dwell specifically on the calculational aspects of applying the hadronic EDM constraints, reviewing in detail the application of QCD sum-rules to the calculation of nucleon EDMs and CP-odd pion-nucleon couplings. We also consider the current status of EDMs in the Standard Model, and on the ensuing constraints on the underlying sources of CP-violation in physics beyond the Standard Model, focussing on weak-scale supersymmetry.

Test of postzygotic isolation and parallel inheritance of morphological traits in threespine stickleback (Gasterosteus aculeatus complex)
Creators: name: Clifford, Elisabeth Anne
Publisher: name: University of British Columbia
Year: 2009

description: This thesis investigates post-zygotic reproductive isolation, parallel evolution, and parallel inheritance of morphological characters using two pairs of ecologically differentiated populations of threespine stickleback. These populations represent two evolutionarily distinct lineages, one from Japan and one from Canada, that are each represented by one marine and one stream-dwelling population. I used hybridisation experiments to examine degree of postmating isolation among the four populations. I found no significant reduction in F₁ or F₂ hybrid fitness relative to pure-bred controls. For my fitness measures I used fertilisation and hatching success of F₁ and F₂ hybrids. The lack of postzygotic isolation between populations when genetic relationships and times of divergence are considered is consistent with other postzygotic isolation studies in frogs, salamanders, and Drosophila. I used the hybrid fish created in the first experiment to answer three questions regarding the genetic causes of parallel evolution. First, do the two ecologically similar stream populations show parallel evolution of morphology? Second, are morphological characters evolved in parallel inherited in a similar way? And third, is parallel inheritance the result of changes at exactly the same loci or merely at loci that behave similarly? I used two morphological characters for these analyses: lateral plate number and body shape as quantified by a thin-plate spline analysis. These traits represent the extremes of genetic complexity with lateral plate number being under simple genetic control and body shape representing a polygenic composite character.

description: Lead and tin chalcogenides have been studied widely due to their promising thermoelectric (TE) properties. Further enhancement in their TE efficiency has been reported upon the reduction of the dimension, which is an important feature in modern device fabrications. Using density functional theory combined with the Semi-classical Boltzmann transport theory, we studied the structural, electronic and TE properties of two-dimensional (2D) MX (M = Sn, Pb; X = S, Te) monolayers. Spin-orbit coupling was found to have significant effects on their electronic structure, particularly for the heavy compounds. Structural optimization followed by phonon transport studies prevailed that the rectangular (γ-) phase is energetically the most favorable for SnS and SnTe monolayers, whereas the square structure is found the most stable for PbS and PbTe monolayers. Our results are in good agreement with previous studies. These 2D materials exhibit high Seebeck coefficients and power factors along with low lattice thermal conductivities, which are essential features of good TE materials. The maximum figure of merits (ZT) of 1.04, 1.46, 1.51 and 1.94 are predicted for n-type SnS, SnTe, PBS and p-type PbTe monolayers respectively at 700 K, which are higher than their bulk ZT values. Hence, these monolayers are promising candidates for TE applications.

description: Macht ist ein vielschichtiges soziales Grundphänomen, welches einer starken Tabuisierung innerhalb der Gesellschaft und der Pflege unterliegt. Weiterhin scheint es dialektisch mit dem Begriff der Bildung verbunden zu sein. Aufgrund dessen erfordert es einer besonderen Aufmerksamkeit innerhalb der Ausbildung in einem sozialen, auf Interaktion basierenden Beruf wie der Pflegeausbildung. Im Rahmen einer Masterarbeit wurden vier ausgewählte Curricula und Lehrbücher der Pflegeausbildung dahingehend analysiert, in welcher Art und in welchem Umfang das Thema Macht in der pflegerischen Ausbildung aufgegriffen und berücksichtigt wird und es wurde der Versuch unternommen, hemmende und begünstigende Faktoren bezüglich des Umgangs mit dem Thema zu identifizieren.

description: Verwaltungsformulare, Verträge, Gesetzestexte, die Bedienungsanleitung einer Kaffeemaschine oder auch der Beipackzettel eines Medikaments – jeder kennt solche Texte und fast immer gibt es ein Problem mit der Verständlichkeit. Was wollen die jetzt von mir? Was soll ich machen? Das sind Fragen, die am Ende offen bleiben. Der Leser steht hilflos vor kompliziert und unverständlich, meist auch ermüdend geschriebenen Texten. Eigentlich sollte aber jeder diese Texte verstehen können. Um die Benutzerfreundlichkeit und die Qualität einer Bedienungsanleitung gewährleisten zu können, sind in Normen, wie VDI 4500, DIN EN ISO 121000 und DIN EN 62079, Kriterien bzgl. Inhalt, Layout und Beschaffenheit festgelegt. Bei der Verständlichkeit wird quasi am Minimum angesetzt, weil wirklich jeder die Anleitung verstehen soll. Doch was ist mit denen, die die Anleitung zwar verstehen sollen, aber eben nicht können? Menschen mit geistiger Behinderung werden im Alltag mit einer Vielzahl an Texten konfrontiert, die sie nicht verstehen. Der Textinhalt bleibt somit ein nicht zu lösendes Rätsel. Dass Menschen mit geistiger Behinderung ein selbstbestimmtes und selbstständiges Leben führen können, wird so von vornherein ausgeschlossen. Die Möglichkeit durch Kommunikation an der Gesellschaft teilzunehmen, wird weitestgehend unterbunden. Um diesem Ausschluss entgegenzuwirken, muss bei der Verwendung von Sprache und Erstellung von Texten unmittelbar bei dieser Zielgruppe angesetzt werden, so dass Texte und Sprache der vorhandenen Lesekompetenz entsprechend zugänglich werden. Hier setzt das Konzept Leichte Sprache an. Durch Unterstützung und Förderung beim Einsatz von Leichter Sprache sollen Menschen mit geistiger Behinderung schulische und berufliche Fähigkeiten erwerben und erfolgreich am sozialen Leben teilnehmen können. In der folgenden Arbeit wird, um Diskriminierung vorzubeugen, zunächst die Begrifflichkeit "geistige Behinderung" geklärt und deren Verwendung festgelegt. Dann wird das Konzept Leichte Sprache vorgestellt. Grundlagen von Verständlichkeit im Allgemeinen und bezogen auf die möglichen Zielgruppen, u.a. Menschen mit geistiger Behinderung, werden erläutert. Um feststellen zu können, ob eine Eingrenzung von Texten notwendig ist, bei denen Verständlichkeit gefördert bzw. überprüft werden soll, wird zwischen verschiedenen Textsorten abgegrenzt. So kann schließlich im Ergebnis überprüft werden, ob Leichte Sprache ein Konzept verständlichen Textens ist.
Conscientiousness, students’ goal orientation, and reasoning ability: significance for educational standards

description: Previous studies show that students’ goal orientation and conscientiousness are related to academic performance. Few studies, however, allow conclusions to be drawn about the factor structure of goal orientation and its distinctions from conscientiousness. In a study with N = 145 secondary school students (M = 13.9, SD = 0.85; 41% male), we investigated if the residuals of latent factors of goal orientation are still meaningfully correlated with academic performance and reasoning. Based on structural equation models, we have replicated the theoretically derived four-factor structure and showed that conscientiousness explains 29% of the variance in learning goals and 40% of the variance in work avoidance. Furthermore, we show that the residuals of goal orientation are mainly not significantly related to reasoning or educational standards (only work avoidance correlated with reasoning, and performance goals correlated with educational standards). Educational standards were highly correlated with reasoning. Implications for school practice and possible interventions are discussed.
Analyticity as a Robust Constraint on the LHC Cross Section

description: It is well known that high energy data alone do not discriminate between asymptotic $\ln s$ and $\ln^2s$ behavior of $pp$ and $\bar pp$ cross sections. By exploiting high quality low energy data, analyticity resolves this ambiguity in favor of cross sections that grow asymptotically as $\ln^2s$. We here show that two methods for incorporating the low energy data into the high energy fits give numerically identical results and yield essentially identical tightly constrained values for the LHC cross section. The agreement can be understood as a new analyticity constraint derived as an extension of a Finite Energy Sum Rule.

We prove that an elliptic operator $P$ on $M\_0$ has an invertible perturbation $P+R$ by a lower order operator if an only if its analytic index vanishes. As an application, we determine the $K$-theory groups of groupoid $C^*$--algebras of manifolds with corners.

description: We report on acoustically driven spin resonances in atomic-scale centers in silicon carbide at room temperature. Specifically, we use a surface acoustic wave cavity to selectively address spin transitions with magnetic quantum number differences of $\pm$1 and $\pm$2 in the absence of external microwave electromagnetic fields. These spin-acoustic resonances reveal a non-trivial dependence on the static magnetic field orientation, which is attributed to the intrinsic symmetry of the acoustic fields combined with the peculiar properties of a half-integer spin system. We develop a microscopic model of the spin-acoustic interaction, which describes our experimental data without fitting parameters. Furthermore, we predict that traveling surface waves lead to a chiral spin-acoustic resonance, which changes upon magnetic field inversion. These results establish silicon carbide as a highly-promising hybrid platform for on-chip spin-optomechanical quantum control enabling engineered interactions at room temperature.

description: The ongoing respiratory COVID-19 pandemic has heavily impacted the social and private lives of the majority of the global population. This infection is primarily transmitted via virus-laden fluid particles (i.e., droplets and aerosols) that are formed in the respiratory tract of infected individuals and expelled from the mouth in the course of breathing, talking, coughing, and sneezing. To mitigate the risk of virus transmission, in many places of the world, the public has been asked or even obliged to use face covers. It is plausible that in the years ahead we will see the use of face masks, face shields and respirators become a normal practice in our life. However, wearing face covers is uncomfortable in some situations, like, for example, in summer heat, while staying on beaches or at hotel swimming pools, doing exercises in gyms, etc. Also, most types of face cover become contaminated with time and need to be periodically replaced or disinfected. These nuisances are caused by the fact that face covers are based on material barriers, which prevent inward and outward propagation of aerosol and droplets containing the pathogen. Applying well established gas-particle flow formalism, we study a non-material based protection barrier created by a flow of well directed down stream of air across the front of the open face. The~protection is driven by dragging virus-laden particles inside the width of the air flow and hence, as a consequence, displacing them away from their primary trajectories. The study, shows that such, potentially portable, air curtains can effectively provide both inward and outward protection and serve as an effective personal protective equipment (PPE) mitigating human to human transmission of virus infection like COVID-19.

description: The Quantum Null Energy Condition (QNEC) is a lower bound on the stress-energy tensor in quantum field theory that has been proved quite generally. It can equivalently be phrased as a positivity condition on the second null shape derivative of the relative entropy $S_{\text{rel}}(ρ||σ)$ of an arbitrary state $ρ$ with respect to the vacuum $σ$. The relative entropy has a natural one-parameter family generalization, the Sandwiched Renyi divergence $S_n(ρ||σ)$, which also measures the distinguishability of two states for arbitrary $n\in[1/2,\infty)$. A Renyi QNEC, a positivity condition on the second null shape derivative of $S_n(ρ||σ)$, was conjectured in previous work. In this work, we study the Renyi QNEC for free and superrenormalizable field theories in spacetime dimension $d>2$ using the technique of null quantization. In the above setting, we prove the Renyi QNEC in the case $n>1$ for arbitrary states. We also provide counterexamples to the Renyi QNEC for $n<1$.

description: Left atrial appendage (LAA) is the source of thrombi formation in more than 90% of strokes in patients with nonvalvular atrial fibrillation. Catheter-based LAA occlusion is being increasingly applied as a treatment strategy to prevent stroke. Anatomical complexity of LAA makes percutaneous occlusion commonly performed under transesophageal echocardiography (TEE) and X-ray (XR) guidance especially challenging. Image fusion techniques integrating 3D anatomical models derived from pre-procedural imaging into the live XR fluoroscopy can be applied to guide each step of the LAA closure. Cardiac magnetic resonance (CMR) imaging gains in importance for radiation-free evaluation of cardiac morphology as alternative to gold-standard TEE or computed tomography angiography (CTA). Manual delineation of cardiac structures from non-contrast enhanced CMR is, however, labor-intensive, tedious, and challenging due to the rather low contrast. Additionally, arrhythmia often impairs the image quality in ECG synchronized acquisitions causing blurring and motion artifacts. Thus, for cardiac segmentation in arrhythmic patients, there is a strong need for an automated image segmentation method. Deep learning-based methods have shown great promise in medical image analysis achieving superior performance in various imaging modalities and different clinical applications. Fully-convolutional neural networks (CNNs), especially U-Net, have become the method of choice for cardiac segmentation. In this paper, we propose an approach for automatic segmentation of cardiac structures from non-contrast enhanced CMR images of arrhythmic patients based on CNNs implemented in a multi-stage pipeline. Two-stage implementation allows subdividing the task into localization of the relevant cardiac structures and segmentation of these structures from the cropped sub-regions obtained from previous step leading to efficient and effective way of automated cardiac segmentation.

description: Public perceptions of Robotics and Artificial Intelligence (RAI) are important in the acceptance, uptake, government regulation and research funding of this technology. Recent research has shown that the public's understanding of RAI can be negative or inaccurate. We believe effective public engagement can help ensure that public opinion is better informed. In this paper, we describe our first iteration of a high throughput in-person public engagement activity. We describe the use of a light touch quiz-format survey instrument to integrate in-the-wild research participation into the engagement, allowing us to probe both the effectiveness of our engagement strategy, and public perceptions of the future roles of robots and humans working in dangerous settings, such as in the off-shore energy sector. We critique our methods and share interesting results into generational differences within the public's view of the future of Robotics and AI in hazardous environments. These findings include that older peoples' views about the future of robots in hazardous environments were not swayed by exposure to our exhibit, while the views of younger people were affected by our exhibit, leading us to consider carefully in future how to more effectively engage with and inform older people.

description: Automatische Spracherkennungssysteme (Automatic Speech Recognition - ASR) können derzeit nicht alle Wörter korrekt erkennen und daher noch keine guten Transkriptionen erstellen. Die Qualität der automatischen Spracherkennung wird von vielen Faktoren beeinflusst. Einer davon ist das Vokabular. Je vielfältiger und komplexer die Themen, desto größer die Anzahl der fachspezifischen Wörter ist, die erkannt werden müssen, desto schwieriger ist die Erkennungsaufgabe und desto schlechter sind die Transkriptionsergebnisse. Die Sprachmodelle von automatischen Spracherkennungssystemen müssen durch Training angepasst werden, damit sie auch bei Gebieten mit speziellem Vokabular gute Resultate erzielen können. In dieser Arbeit wird untersucht, ob der prozentuale Anteil der korrekt erkannten Wörter durch Training des Sprachmodells der automatischen Spracherkennung mit fachspezifischer Terminologie wirksam gesteigert werden kann. Anhand von Ergebnissen der durchgeführten Experimente wird dargelegt, welche Anzahl und Art von Daten benötigt wird, um den Prozentsatz der falsch erkannten Wörter zu senken. Die Ergebnisse der Domänen-Adaption bilden die Basis für den anschließenden Vergleich des fachspezifischen Vokabulars in Vorlesungsvideos und wissenschaftlichen Publikationen, um die Unterschiede hinsichtlich der verwendeten Fachsprache aufzuzeigen. Grundlage und Ausgangspunkt für die gesamte Untersuchung stellt die Erkennung der Fachterminologie und ihre Unterscheidung von der Allgemeinsprache dar.

description: The Holevo bound is a bound on the mutual information for a given quantum encoding. In 1996 Schumacher, Westmoreland and Wootters [Schumacher, Westmoreland and Wootters, Phys. Rev. Lett. 76, 3452 (1996)] derived a bound which reduces to the Holevo bound for complete measurements, but which is tighter for incomplete measurements. The most general quantum operations may be both incomplete and inefficient. Here we show that the bound derived by SWW can be further extended to obtain one which is yet again tighter for inefficient measurements. This allows us in addition to obtain a generalization of a bound derived by Hall, and to show that the average reduction in the von Neumann entropy during a quantum operation is concave in the initial state, for all quantum operations. This is a quantum version of the concavity of the mutual information. We also show that both this average entropy reduction, and the mutual information for pure state ensembles, are Schur-concave for unitarily covariant measurements; that is, for these measurements, information gain increases with initial uncertainty.

description: Cranioplasty (CP) after decompressive hemicraniectomy (DHC) is a common neurosurgical procedure with a high complication rate. The best material for the repair of large cranial defects is unclear. The aim of this study was to evaluate different implant materials regarding surgery related complications after CP. Type of materials include the autologous bone flap (ABF), polymethylmethacrylate (PMMA), calcium phosphate reinforced with titanium mesh (CaP-Ti), polyetheretherketone (PEEK) and hydroxyapatite (HA). A retrospective, descriptive, observational bicenter study was performed, medical data of all patients who underwent CP after DHC between January 1st, 2016 and December 31st, 2022 were analyzed. Follow-up was until December 31st, 2023. 139 consecutive patients with a median age of 54 years who received either PMMA (56/139; 40.3%), PEEK (35/139; 25.2%), CaP-Ti (21/139; 15.1%), ABF (25/139; 18.0%) or HA (2/139; 1.4%) cranial implant after DHC were included in the study. Median time from DHC to CP was 117 days and median follow-up period was 43 months. Surgical site infection was the most frequent surgery-related complication (13.7%; 19/139). PEEK implants were mostly affected (28.6%; 10/35), followed by ABF (20%; 5/25), CaP-Ti implants (9.5%; 2/21) and PMMA implants (1.7%, 1/56). Explantation was necessary for 9 PEEK implants (25.7%; 9/35), 6 ABFs (24.0%; 6/25), 3 CaP-Ti implants (14.3%; 3/21) and 4 PMMA implants (7.1%; 4/56). Besides infection, a postoperative hematoma was the most common cause. Median surgical time was 106 min, neither longer surgical time nor use of anticoagulation were significantly related to higher infection rates (p = 0.547; p = 0.152 respectively). Ventriculoperitoneal shunt implantation prior to CP was noted in 33.8% (47/139) and not significantly associated with surgical related complications. Perioperative lumbar drainage, due to bulging brain, inserted in 38 patients (27.3%; 38/139) before surgery was protective when it comes to explantation of the implant (p = 0.035). Based on our results, CP is still related to a relatively high number of infections and further complications. Implant material seems to have a high effect on postoperative infections, since surgical time, anticoagulation therapy and hydrocephalus did not show a statistically significant effect on postoperative complications in this study. PEEK implants and ABFs seem to possess higher risk of postoperative infection. More biocompatible implants such as CaP-Ti might be beneficial. Further, prospective studies are necessary to answer this question.

description: With a sample of nearly 18,611 utility patents, this paper studies the technology mix of 90 of the world's leading food and beverage multinationals (FBMs) over 1969-1994. It explores the statistical association between patenting in food technology and in non-food technological fields. Food patenting is always associated with patenting in Biotech, Chemistry, Machinery and Other patenting, whatever the home country of the company. The strength of the association, however, could vary. Herfindahl indices show that capabilities in core technology and in Machinery and Other fields are spread among many FBMs. Though to a lesser extent, technical capabilities in Biotechnology, Packaging and Refrigeration are also dispersed. By contrast, patenting in Tobacco, Chemistry and Drugs is concentrated.

description: In einem Artikel der Zeitschrift Die Zeit wird die Generation Y, die Generation deren Angehörige derzeit zum Großteil ihre akademische Ausbildung beenden und sich dem Arbeitsmarkt zuwenden, auch als Generation Pippi, angelehnt an Astrid Lindgrens Kinderbuchheldin Pippi Langstrumpf, bezeichnet (Bund et al., 2013: 1). Individualität, eine ausgeprägte Abneigung gegenüber Autoritätspersonen, der Wunsch nach Spaß und Abwechslung sowie das Bestreben, sich selbst zu verwirklichen, charakterisieren Pippi Langstrumpf (Bund et al., 2013: 1). Diese Charakterbeschreibungen werden z. T. auf die Generation Y übertragen und stellen Unternehmen vor eine Herausforderung: Um Arbeitnehmer der Generation Y affektiv zu binden, so dass sich in diese getätigte und noch zu tätigenden Investitionen rentieren, müssen neue Strategien entwickelt werden. Innerhalb dieser Bachelorarbeit konnten erste Erkenntnisse dahingehend gewonnen werden, dass u. a. Work-Life-Balance Maßnahmen, (gesundheitsorientierte) Führung, ein positives Arbeitsklima und Mitbestimmung als Auslöser affektiven organisationalen Commitments der Generation Y fungieren können. Bei der nachfolgend dargestellten Arbeit handelt es sich um eine überarbeitete Version der gleichnamigen Bachelorarbeit, die von Prof. Dr. Sven Litzcke sowie von Prof. Dr. Dr. Daniel Wichelhaus betreut wurde.
description: An article of the journal Die Zeit describes Generation Y, the generation a large part of is completing their academic education and turns to the labor market, as generation Pippi, leaning on Astrid Lindgren's children's book heroine Pippi Longstocking (Bund et al., 2013: 1). Individuality, a distinct aversion to authority, a longing for fun and variety as well as the desire of individual fulfillment characterize Pippi Longstocking (Bund et al, 2013: 1). These characteristics are transferred to Generation Y and in some cases companies have to meet a chal-lenge: to affectively attach employees of Generation Y, so that investments al-ready made and yet to be done turn out to be profitable, new strategies must be developed. This thesis gives initial results concerning the effect of work-life-balance measures, (health-oriented) leadership, a positive working environment and participation to serve as positive triggers stimulating the affective organiza-tional commitment of Generation Y. The following assignment is a revised edi-tion of the bachelor thesis with the same name, which was supervised by Prof. Dr. Sven Litzcke and Prof. Dr. Dr. Daniel Wichelhaus.

Transverse momentum fluctuations and their correlation with elliptic flow in nuclear collision

description: We propose observables $v_0$ and $v_0(p_T)$ which quantify the relative fluctuations in the total transverse momentum at fixed multiplicity. We first study the factorization of the fixed multiplicity momentum dependent two particle correlation function into a product of $v_0(p_T^a)$ and $v_0(p_T^b)$ within realistic hydrodynamic simulations. Then we present computations of $v_0(p_T)$ for different particle types. We determine the relation between the integrated $v_0$ and previously measured observables, and compare results from a hybrid hydrodynamics based model to experimental data. The effects of bulk viscosity and an initial pre-equilibrium stage on the results are quantified. We find that $v_0$ is strongly correlated with the initial state entropy per elliptic area, $S/A$. Using this result, we explain how the observed correlations between the elliptic flow and the transverse momentum (both in simulations and experiment) reflect the initial state correlations between $1/A$ and ellipticity $\varepsilon_2$ at fixed multiplicity. We argue that the systematic experimental study of $v_0$, with the same sophistication as used for the other $v_n$, can contribute significantly to our understanding of quark gluon plasma properties.

description: In der vorliegenden Arbeit wurde für die Erhebung von rheologischen Parametern ein großmaßstäbliches Rohrviskosimeter verwendet. Originalproben aus fünf Biogasfermentern und Nachgärern wurden mit variiertem Volumenstrom durch verschieden dimensionierte Messrohrstrecken im Kreis gefördert. Über definierte Längen der Messrohrstrecken konnte der Differenzdruck bei laminarem Strömungsverhalten aufgenommen werden. Aus den geometrischen Größen sowie den Wertepaaren Volumenstrom und Differenzdruck ließen sich nach einer Korrektur der Schergeschwindigkeit die Parameter für die Abbildung der absoluten Fließ- und Viskositätseigenschaften nach dem Potenzansatz approximieren.
Three dimensional quantum electrodynamics and cuprate superconductivity
Creators: name: Davis, Thomas P.
Publisher: name: University of British Columbia
Year: 2009

description: The ubiquitous phase diagram of the cuprate superconductors has a phase where the density of states still has a gap above the superconducting transition temperature. Due to the presence of a gap without any other superconducting characteristics, this phase is known as the pseudogap (PG) state. Emery and Kivelson proposed that in this state the superconducting order parameter still has a finite amplitude, however the quantal phase is disordered in such a way that it does not possess long range order. Using these ideas, Franz and Tesanovic developed a theory to explain the pseudogap phase that is identical to three dimensional quantum electrodynamics (QED3 ) apart from an intrinsic anisotropy. Amazingly, this theory can easily explain the antiferromagnetic region. The main purpose of this thesis is twofold. First, to explore some finite temperature properties of QED3 . We do this by calculating a Bosonic polarization bubble at finite temperature in the Matsubara formalism. Secondly we wish to derive some experimentally testable predictions of QED3 . To this end we calculate the modification to the Patrick Lee universal conductivity in the pseudogap state.

description: Most quality properties of food products can be considered as credence characteristics, quality of which cannot be inferred before the purchase, and sometimes not even after the purchase. Our objectives are: (1) To assess how much consumers are willing to pay (WTP) for meat products, of which e.g. origins and production practices are known, especially with regard to safety issues; (2) To compare the applicability, reliability, and efficiency of safety information provided by either private companies or public institutions, and (3) to explore the possibility of the so-called information paradox: is more information always better - or more beneficial - information?

description: We derive analytical expressions for the quasiparticle lifetime tau, the effective mass m*, and the Green's function renormalization factor Z for a 2D Fermi liquid with electron-electron interaction in the presence of the Rashba spin-orbit interaction. We find that the modifications are independent of the Rashba band index rho, and occur in second order of the spin-orbit coupling alpha. In the derivation of these results, we also discuss the screening of the Coulomb interaction, as well as the susceptibility and the self-energy in small alpha.

description: In many applications, identity management (IdM) is used to associate a subject public key with an endpoint at which the subject can be contacted (telephone number, email, etc.). In decentralized applications based on distributed ledger technologies (DLTes), it is desirable for the IdM to be decentralized as well. Currently, endpoints are either verified by who needs it, which is impractical in DLT-based applications, or by a centralized authority, which contrasts with the spirit of DLTes. In this paper, we show two DLT-based protocols to prove the association between a subject and an endpoint in a decentralized manner, contributing in filling the gap of the current IdM approaches with respect to decentralization. Our protocols are compatible with a wide variety of endpoints. We analyze the security of our protocols and evaluate their performance and cost against the common approaches.
