description: Die vorliegende Arbeit beschäftigt sich mit dem Konzept von Markenaktivismus, das in der heutigen Welt stetig an Bedeutung gewinnt. Markenaktivismus bezeichnet dabei die Positionierung eines Unternehmens zu den soziopolitischen Problemstellungen ihrer Kund:innen. Entsprechen diese Probleme auch den Werten eines Unternehmen so können sie sich dazu äußern und auch soziopolitisch aktiv werden. Im Rahmen dieser Masterarbeit wurde eine quantitative Forschung durchgeführt, in der untersucht wird, ob der vorherrschende Entscheidungstyp im Unternehmen, der Industrietyp und die Größe des Unternehmens wie auch ihre organisatorische Struktur Einfluss darauf haben, ob das Unternehmen Stellung bezieht. Dabei wurden 151 Marketer:innen in einer Onlineumfrage, zu den in ihren Unternehmen vorhanden Vorgehensweisen betreffend der bereits erwähnten Faktoren, befragt. Diese Masterarbeit liefert wichtige Ansätze, um Marketingverantwortlichen in Unternehmen dabei zu helfen, zu erkennen, was im Zusammenhang mit einer Entscheidung bezüglich Markenaktivismus wichtig ist. Unter anderem werden vom Autor dieser Arbeit weiterführende Forschungsaspekte im Zusammenhang mit Markenaktivismus beleuchtet und begründet.
description: This paper deals with the concept of brand activism, which is becoming increasingly important in today's world. Brand activism refers to the positioning of a company towards the socio-political problems of its customers. If these problems correspond to the values of a company, it may express itself and become socio-politically active. In the context of this master’s thesis, quantitative research was conducted to investigate whether the predominant decision-making type in the company, the type of the company, the size of the company but also its organizational structure has an influence on whether a company may take a stand. In an online survey, 151 brand managers and company owners were asked about the procedures in their companies regarding the factors already mentioned above. This master's thesis provides important approaches to help marketing managers within companies to understand the importance of decision-making in context with taking a socio-political stand through brand activism. Furthermore, the author of this thesis highlights further research aspects in connection with brand activism.

description: We study the impact on the primordial abundances of light elements created by a variation of the quark masses at the time of Big Bang nucleosynthesis (BBN). In order to navigate through the particle and nuclear physics required to connect quark masses to binding energies and reaction rates in a model-independent way, we use lattice QCD data and a hierarchy of effective field theories. We find that the measured Helium-4 abundances put a bound of -1 %

description: Die vorliegende Masterarbeit befasst sich mit der Untersuchung der Kernherausforderungen für Unternehmen in Österreich bei der Entwicklung einer digitalen Marketingstrategie und setzt den Fokus auf Social Media. Die Arbeit verfolgt das Ziel, die Kernherausforderungen aufzuzeigen und Handlungsempfehlungen abzuleiten. Im Zuge der empirischen Untersuchung wurden mit Hilfe von Case Studies und darauf aufbauenden Interviews drei Unternehmen im Dienstleistungsbereich betrachtet, um eine möglichst präzise und valide Datengrundlage zu schaffen. Die Ergebnisse zeigen fundamentale Kernherausforderungen für Unternehmen bei der Strategieentwicklung auf, die sich auf den Ressourceneinsatz und fehlendem Know-how ableiten. Ein weiterer Punkt der Untersuchung definiert den budgetären Einsatz, welcher wiederrum in der strategischen Ausrichtung berücksichtigt werden muss. Insgesamt trägt die Masterarbeit dazu bei, für Unternehmen bei der Entwicklung einer digitalen Marketingstrategie Kernherausforderungen aufzuzeigen und diese zu vermeiden, indem auf Modelle und Prozesse verwiesen wird.
description: This master's thesis examines the core challenges for companies in Austria in developing a digital marketing strategy with a focus on social media. The aim of the thesis is to identify the core challenges and to derive recommendations for action. In the course of the empirical investigation, three companies in the service sector were examined with the help of case studies and interviews based on them in order to create a data basis that is as precise and valid as possible. The results show fundamental core challenges for companies in strategy development, which are derived from the use of resources and the lack of knowhow. A further point of the investigation defines the budgetary employment, which must be considered again in the strategic adjustment. Overall, the master's thesis helps to identify core challenges for companies in the development of a digital marketing strategy and to avoid them by referring to models and processes.

description: The first calculation of the next-to-leading-order electroweak corrections to Z-boson + jet hadroproduction including leptonic Z-boson decays is presented, i.e. to the production of a charged lepton--anti-lepton final state in association with one hard jet at the LHC and the Tevatron. The Z-boson resonance is treated consistently using the complex-mass scheme, and all off-shell effects as well as the contributions of the intermediate photon are taken into account. The corresponding next-to-leading-order QCD corrections have also been recalculated. The full calculation is implemented in a flexible Monte Carlo code. Numerical results for cross sections and distributions of this Standard Model benchmark process are presented for the Tevatron and the LHC.

description: A series of experiments is carried out to identify the contribution of interface and bulk antiferromagnetic (AFM) spins to exchange bias (EB) in ultrathin epitaxial ferromagnetic (FM)/AFM bilayer samples. These are single-crystalline AFM Ni𝑥Mn100−𝑥 and ferromagnetic Co layers on Cu3Au(001), deposited under ultrahigh vacuum conditions, in which structural or chemical defects are deliberately introduced by controlled Ar ion sputtering at the surface of the AFM layer or at a certain depth inside the AFM layer. Comparison of the magnetic properties measured by magneto-optical Kerr effect for sputtered and nonsputtered parts of the same sample then allows a precise determination of the influence of sputtering on the AFM layer during the sample preparation, whereas all other parameters are kept identical. The results show that the creation of defects in the bulk of the AFM layer enhances the magnitude of EB and its blocking temperature, but not the creation of defects at the interface. It is also observed that the deeper the insertion of defects in the AFM layer, the higher the value of the EB field and the larger the coercivity, These findings are discussed as the effect of additional pinning centers in the bulk of the AFM layer.

description: In cake filtration, shrinkage cracking is an undesirable phenomenon as it leads to deterioration of the filtration process in terms of residual moisture, gas consumption and overall cost. Whereas shrinkage cracking has been extensively studied for thermal drying, there is little research on shrinkage and cracking behavior in a filtration process. Aim of this work is to investigate the relationship of dewatering, shrinkage and crack onset and propagation for compressible filter cakes during vacuum filtration. We combine an image analysis technique with laser displacement measurements to investigate in-plane and vertical shrinkage during cake dewatering. The influence of the boundary on cracking behavior and the saturation at crack onset are determined. The influence of filtration pressure on crack area and crack propagation speed will be discussed.

description: We study the stability of resonance poles in pi-N P_11 partial wave, particularly the Roper resonance, by varying parameters significantly within the EBAC dynamical coupled-channels model, keeping a good fit to the empirical amplitude. We find that two Roper poles are stable against the variation. However, for higher energies, the number of poles can change depending on how the parameters are fitted within error bars. We also developed a model with a bare nucleon which forms the physical nucleon by being dressed by the meson-cloud. We still find a good stability of the Roper poles.

Το σύγχρονο περιβάλλον, ως εξαιρετικά αβέβαιο, θα πρέπει να λειτουργεί ευνοϊκά προς την ανάπτυξη της επιχειρηματικότητας για αρκετούς λόγους και ο πρώτος είναι η αποδοτικότητα και η ποιότητα των παρεχόμενων υπηρεσιών. Επίσης η καινοτομία, η ανάπτυξη νέων προϊόντων ή υπηρεσιών και η βελτίωση υπαρχόντων προϊόντων ή υπηρεσιών αποτελούν σημαντικές διακλαδώσεις της επιχειρηματικότητας που μπορούν να ενισχύσουν την οικονομική και κοινωνική ανάπτυξη μιας χώρας.

Σκοπός της παρούσας μελέτης είναι η διερεύνηση των επιχειρηματικών προσανατολισμών και προθέσεων δώδεκα Πανεπιστημίων της Ελλάδας όσον αφορά τις στρατηγικές τους δηλώσεις, τις δημόσιες δηλώσεις σχετικά με τη φιλοσοφία, τις αξίες και τους κανόνες, τα κέντρα επιχειρηματικότητας, τις λέσχες επιχειρηματικότητας και δραστηριότητες κατάρτισης των φοιτητών που προάγουν την ιδέα της δημιουργικής επιχειρηματικότητας. Τα αποτελέσματα της έρευνας που διεξήχθη με τη μέθοδο της ανάλυσης περιεχομένου, έδειξαν ότι τα οχτώ από τα δώδεκα πανεπιστήμια της Ελλάδας ενσωματώνουν τις έννοιες της επιχειρηματικότητας στους στρατηγικούς τους στόχους, χωρίς όμως ουσιαστικές προτάσεις εφαρμογής. Ως προς την οργάνωση και τη λειτουργία τους διαπιστώνεται η υιοθέτηση κάποιων πρακτικών που συνδέονται με την επιχειρηματικότητα ωστόσο όμως υπάρχουν πολλές ακόμα ενέργειες που θα πρέπει να γίνουν.

Phase diagrams of binary mixtures of patchy colloids with distinct numbers of patches: The network fluid regime

description: We calculate the network fluid regime and phase diagrams of binary mixtures of patchy colloids, using Wertheim's first order perturbation theory and a generalization of Flory-Stockmayer's theory of polymerization. The colloids are modelled as hard spheres with the same diameter and surface patches of the same type, $A$. The only difference between species is the number of their patches -or functionality-, $f_A^{(1)}$ and $f_A^{(2)}$ (with $f_A^{(2)}>f_A^{(1)}$). We have found that the difference in functionality is the key factor controlling the behaviour of the mixture in the network (percolated) fluid regime. In particular, when $f_A^{(2)}\ge2f_A^{(1)}$ the entropy of bonding drives the phase separation of two network fluids which is absent in other mixtures. This changes drastically the critical properties of the system and drives a change in the topology of the phase diagram (from type I to type V) when $f_A^{(1)}>2$. The difference in functionality also determines the miscibility at high (osmotic) pressures. If $f_A^{(2)}-f_A^{(1)}=1$ the mixture is completely miscible at high pressures, while closed miscibility gaps at pressures above the highest critical pressure of the pure fluids are present if $f_A^{(2)}-f_A^{(1)}>1$. We argue that this phase behaviour is driven by a competition between the entropy of mixing and the entropy of bonding, as the latter dominates in the network fluid regime.

description: Excerpt from the report: Shipments of Western iceberg lettuce account for approximately 20 percent of all carlots of fresh fruits and vegetables shipped from California. Agricultural engineers in the Agricultural Research Service, U.S. Department of Agriculture, have developed a mechanical lettuce harvester. With present packaging methods, the machine is limited by the rate at which the crew can trim and pack the lettuce coming off the machine. The purpose of the study was to provide up-to-date information on current practices, trends, and problems that are encountered during the handling and marketing of lettuce and to determine changes other commodity groups are making.

description: Supersymmetric models based on the scenario of gague mediation often suffer from the well-known $μ$ problem. In this paper, we reconsider this problem in low-scale gauge mediation in terms of effective field theory analysis. In this paradigm, all high energy input soft mass can be expressed via loop expansions. If the corrections coming from messenger thresholds are small, as we assume in this letter, then RG evaluations can be taken as linearly approximation for low-scale supersymmetric breaking. Due to these observations, the parameter space can be systematically classified and studied after constraints coming from electro-weak symmetry breaking are imposed. We find that some old proposals in the literature are reproduced, and two new classes are uncovered. We refer to a microscopic model, where the specific relations among coefficients in one of the new classes are well motivated. Also, we discuss some primary phenomenologies.

description: We investigate dynamics arising after an interaction quench in the quantum sine-Gordon model for a one-dimensional system initially prepared in a spatially inhomogeneous domain wall state. We study the time-evolution of the density, current and equal time correlation functions using the truncated Wigner approximation (TWA) to which quantum corrections are added in order to set the limits on its validity. For weak to moderate strengths of the back-scattering interaction, the domain wall spreads out ballistically with the system within the light cone reaching a nonequilibrium steady-state characterized by a net current flow. A steady state current exists for a quench at the exactly solvable Luther-Emery point. The magnitude of the current decreases with increasing strength of the back-scattering interaction. The two-point correlation function of the variable canonically conjugate to the density reaches a spatially oscillating steady state at a wavelength inversely related to the current.

description: Interactions between the inflaton and any additional fields can lead to isolated bursts of particle production during inflation (for example from parametric resonance or a phase transition). Inflationary particle production leaves localized features in the spectrum and bispectrum of the observable cosmological fluctuations, via the Infra-Red (IR) cascading mechanism. We focus on a simple prototype interaction g^2 (ϕ-ϕ_0)^2χ^2 between the inflaton, ϕ, and iso-inflaton, χ; extending previous work on this model in two directions. First, we quantify the magnitude of the produced nongaussianity by extracting the moments of the probability distribution function from lattice field theory simulations. We argue that the bispectrum feature from particle production might be observable for reasonable values of the coupling, g^2. Second, we develop a detailed analytical theory of particle production and IR cascading during inflation, which is in excellent agreement with numerical simulations. Our formalism improves significantly on previous approaches by consistently incorporating both the expansion of the universe and also metric perturbations. We use this new formalism to estimate the shape of the bispectrum from particle production, showing this to be distinguishable from other mechanisms that predict large nongaussianity.

description: Mast cell-activating signals in cold urticaria are not yet well defined and are likely to be heterogeneous. Cold agglutinins and cryoglobulins have been described as factors possibly associated with cold urticaria, but their relevance has not been explained. We performed a single-center prospective cohort study of 35 cold urticaria patients. Cold agglutinin and cryoglobulin test results, demographics, detailed history data, cold stimulation test results, complete blood count values, C-reactive protein, total immunoglobulin E levels, and basal serum tryptase levels were analyzed. Forty six percent (n = 16) of 35 tested patients had a positive cold agglutinin test and 27% (n = 9) of 33 tested patients had a positive cryoglobulin test. Cold agglutinin positive patients, when compared to cold agglutinin negative ones, were mainly female (P = 0.030). No gender-association was found for cryoglobulins. A positive cold agglutinin test, but not a positive cryoglobulin test, was associated with a higher rate of reactions triggered by cold ambient air (P = 0.009) or immersion in cold water (P = 0.041), and aggravated by increased summer humidity (P = 0.007). Additionally, patients with a positive cold agglutinin test had a higher frequency of angioedema triggered by ingestion of cold foods or drinks (P = 0.043), and lower disease control based on Urticaria Control Test (P = 0.023). Cold agglutinin levels correlated with erythrocyte counts (r = -0.372, P = 0.028) and monocyte counts (r = -0.425, P = 0.011). Cryoglobulin concentrations correlated with basal serum tryptase levels (r = 0.733, P = 0.025) and cold urticaria duration (r = 0.683, P = 0.042). Results of our study suggest that cold agglutinins and cryoglobulins, in a subpopulation of cold urticaria patients, are linked to the course and possibly the pathogenesis of their disease.

description: Background: Ependymomas are rare neoplasms of the central nervous system (CNS), usually localized intracranially and most commonly diagnosed in children. Spinal ependymomas are more frequent in young adults. They are either primary lesions or manifest as disseminated seeding of cranial tumors. Data on the management of spinal ependymoma lesions remain scarce, especially concerning stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT). The purpose of this study is to report the treatment outcomes of two institutions using robotic radiosurgery (RRS) for the treatment of spinal ependymomas. Materials and Methods: All patients with a histopathologically confirmed diagnosis of an ependymoma WHO grade II or III who were treated with RRS for one or more spinal lesions were included in this analysis. Results: Twelve patients underwent RRS for the treatment of 32 spinal ependymoma lesions between 2005 and 2020. Two patients were below the age of 18 when treated, whereas nine patients (75%) suffered from a primary spinal ependymoma. The median dose was 15 Gy prescribed to a median isodose of 70%, with 27 lesions (84%) receiving a single-session treatment. The local control (LC) after a median follow-up of 56.7 months was 84%. LC rates at 1, 3, and 5 years were 92, 85, and 77%, respectively. The Kaplan-Meier estimated overall survival after 1, 3, and 5 years were 75, 75, and 64%, respectively. Five patients died, all of them suffering from an anaplastic ependymoma, with widespread CNS tumor progression being the reason for death in four patients. The majority of patients (58%) showed a stable neurological status at the last available follow-up. Overall, the treatment was well tolerated. Conclusion: RRS appears to be a safe and efficient treatment modality for managing primary and secondary spinal ependymal tumors in patients with multiple lesions and local recurrences.
The thermodynamic Casimir force: A Monte Carlo study of the crossover between the ordinary and the normal surface universality class

Year: 2010

description: We study the crossover from the ordinary to the normal surface universality class in the three-dimensional Ising universality class. This crossover is relevant for the behavior of films of binary mixtures near the demixing point and a weak adsorption at one or both surfaces. We perform Monte Carlo simulations of the improved Blume-Capel model on the simple cubic lattice. We consider systems with film geometry, where various boundary conditions are applied. We discuss corrections to scaling that are caused by the surfaces and their relation with the so called extrapolation length. To this end we analyze the behavior of the magnetization profile near the surfaces of films. We obtain an accurate estimate of the renormalization group exponent y_{h_1}=0.7249(6) for the ordinary surface universality class. Next we study the thermodynamic Casimir force in the crossover region from the ordinary to the normal surface universality class. To this end, we compute the Taylor-expansion of the crossover finite size scaling function up to the second order in h_1 around h_1=0, where h_1 is the external field at one of the surfaces. We check the range of applicability of the Taylor-expansion by simulating at finite values of h_1. Finally we study the approach to the strong adsorption limit h_1 \rightarrow \infty. Our results confirm the qualitative picture that emerges from exact calculations for stripes of the two-dimensional Ising model, [D. B. Abraham and A. Maciolek, Phys. Rev. Lett. 105, 055701 (2010)], mean-field calculations and preliminary Monte Carlo simulations of the 3D Ising model, [T. F. Mohry et al, Phys. Rev. E 81, 061117 (2010)]: For certain choices of h_1 and the thickness of the film, the thermodynamic Casimir force changes sign as a function of the temperature and for certain choices of the temperature and h_1, it also changes sign as a function of the thickness of the film.

description: Background: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease with an adverse impact on patients' quality of life (QoL). Objectives: To quantify QoL impairment in patients in Germany suffering from HS and to identify the parameters associated with QoL impairment. Methods: A non-interventional, cross-sectional, mono-centric study with 500 HS patients. QoL data (measured using the Dermatology Life Quality Index; DLQI) and demographic, anamnestic, clinical, and blood parameters were collected. All patients were examined by dermatologists that documented the skin alterations. QoL data from 462 HS patients were available and evaluated. Results: The mean (+/- standard deviation) DLQI score of HS patients was 13.18 +/- 7.99. Approximately 40% and 20% of HS patients declared very large and extremely large QoL impairment, respectively. The degree of QoL disturbance correlated with the severity of skin alterations, blood leucocyte count and, in particular, with anogenital localization and the presence of nodules and fistulas. Furthermore, QoL impairment was associated with specific comorbidities, such as adiposity and back pain, but not with HS family history. QoL impairment was not influenced by whether or not the patients had undergone resection surgery or antibiotic treatment but was more severe in HS patients that had undergone abscess lancing compared to patients without such treatment in the past. Limitations: It was a mono-centric study and most data were obtained from self-administered patient questionnaires. The association of QoL with type of treatment was analyzed for abscess lancing, resection surgery, and antibiotic treatment. Further therapeutic modalities recommended in the guidelines were not investigated. Conclusion: A profound impairment in QoL was present in patients with HS, and this was higher than that observed in other studied dermatoses. The degree of impairment correlated with the extent of cutaneous and some extra-cutaneous alterations. Surgical and conventional medicamentous therapies of HS were not associated with long-lasting reduction of QoL impairment. Our data support the implementation of patient-reported outcome measures for the assessment of therapy responses.

description: We study leptogenesis in the supersymmetric standard model plus the seesaw. We identify important qualitative differences that characterize supersymmetric leptogenesis with respect to the non-supersymmetric case. The lepton number asymmetries in fermions and scalars do not equilibrate, and are related via a non-vanishing gaugino chemical potential. Due to the presence of new anomalous symmetries, electroweak sphalerons couple to winos and higgsinos, and QCD sphalerons couple to gluinos, thus modifying the corresponding chemical equilibrium conditions. A new constraint on particles chemical potentials corresponding to an exactly conserved $R$-charge, that also involves the number density asymmetry of the heavy sneutrinos, appears. These new ingredients determine the $3\times 4$ matrices that mix up the density asymmetries of the lepton flavours and of the heavy sneutrinos. We explain why in all temperature ranges the particle thermodynamic system is characterized by the same number of independent quantities. Numerical differences with respect to usual treatment remain at the ${\cal O}(1)$ level.

description: The implementation of immune checkpoint inhibitors (ICI) into the clinical management of different malignancies has largely changed our understanding of cancer treatment. After having proven efficacy in different tumor entities such as malignant melanoma and lung cancer, ICI were intensively tested in the setting of hepatocellular carcinoma (HCC). Here they could achieve higher and more durable response rates compared to tyrosine-kinase inhibitors (TKI), that were sole standard of care for the last decade. Most recently, ICI treatment was approved in a first line setting of HCC, for cases not suitable for curative strategies. However, only a subset of patients benefits from ICI therapy, while others experience rapid tumor progression, worsening of liver function and poor prognosis. Efforts are being made to find immune characteristics that predict tumor responsiveness to ICI, but no reliable biomarker could be identified so far. Nevertheless, data convincingly demonstrate that combination therapies (such as dual inhibition of PD-L1 and VEGF) are more effective than the application of single agents. In this review, we will briefly recapitulate the current algorithms for systemic treatment, discuss available results from checkpoint inhibitor trials and give an outlook on future directions of immunotherapy in HCC.

description: The intestinal epithelium is a complex, dynamic barrier that separates luminal contents from the immune compartment while mediating nutrient absorption and controlled passage of antigens to convey oral tolerance. A compromised epithelial barrier often leads to inflammation because immune cells in the lamina propria come into direct contact with luminal antigens. Defects in epithelial cell function were also shown to be involved in the etiology of inflammatory bowel diseases. These are severe, chronically relapsing inflammatory conditions of the gastrointestinal tract that also increase the risk of developing colorectal cancer. Despite major efforts of the scientific community, the precise causes and drivers of these conditions still remain largely obscured impeding the development of a permanent cure. Current therapeutic approaches mostly focus on alleviating symptoms by targeting immune cell signaling. The protein family of histone deacetylases (HDACs) has gained increasing attention over the last years, as HDAC inhibitors were shown to be potent tumor cell suppressors and also alleviate morbid inflammatory responses. Recent research continuously identifies new roles for specific HDACs suggesting that HDACs influence the cell signaling network from many different angles. This makes HDACs very interesting targets for therapeutic approaches but predicting effects after system manipulations can be difficult. In this review, we want to provide a comprehensive overview of current knowledge about the individual roles of HDACs in the intestinal epithelium to evaluate their therapeutic potential for inflammatory conditions of the gut.

description: Forkhead box O 3 (FOXO3) is a transcription factor involved in cell metabolism, inflammation and longevity. Here, we investigated if metformin can activate FOXO3 in human immune cells and affects the subsequent level of reactive oxygen/nitrogen species (ROS/RNS) in immune cells. AMP-activated protein kinase (AMPK) and FOXO3 activation were investigated by immunoblot or flow cytometry (FC) analysis, respectively. FOXO3 target gene expression was quantified by real-time PCR. ROS/RNS measurement using dichlorodihydrofluorescein diacetate (DCFH-DA) dye was investigated by FC. The role of the FOXO3 single nucleotide polymorphisms (SNPs) rs12212067, rs2802292 and rs12206094 on ROS/RNS production was studied using allelic discrimination PCR. Metformin induced activation of AMPK (pT172) and FOXO3 (pS413). ROS/RNS level was reduced in immune cells after metformin stimulation accompanied by induction of the FOXO3 targets mitochondrial superoxide dismutase and cytochrome c. Studies in Foxo3 deficient (Foxo3(-/-) ) mouse splenocytes confirmed that metformin mediates its effects via Foxo3 as it attenuates ROS/RNS in myeloid cells of wildtype (WT) but not of Foxo3(-/-) mice. Our results suggest that FOXO3 can be activated by metformin leading to reduced ROS/RNS level in immune cells. This may add to the beneficial clinical effects of metformin observed in large cohort studies on longevity, cardiovascular and cancer risk.

description: We analyze the dc Josephson effect in a ballistic superconductor/ferromagnet/superconductor junction by means of the Bogoliubov-de Gennes equations in the quasiclassical Andreev approximation. We consider the possibility of ferromagnetism originating from a mass renormalization of carriers of opposite spin, i.e. a spin bandwidth asymmetry. We provide a general formula for Andreev levels which is valid for arbitrary interface transparency, exchange interaction, and bandwidth asymmetry. We analyze the current-phase relation, the critical current, and the free energy in the short junction regime. We demonstrate that a larger number of $0-π$ transitions caused by a change in junction width or polarization magnitude is expected when ferromagnetism is driven by spin bandwidth asymmetry compared to Stoner magnetism, and that the same mechanism is likely responsible for the flowing of a larger critical current. We compare the phase diagrams of two identical junctions differing only in the mechanism by which the mid layer becomes magnetic, i.e. Stoner magnetism or bandwidth asymmetry. In particular, we point out that for these two cases, the phase difference across the junction in the ground state need not be the same, even if the polarizations are equal.

description: Despite the acceleration of knowledge and data accumulation in neuroscience over the last years, the highly prevalent neurodegenerative disease of AD remains a growing problem. Alzheimer's Disease (AD) is the most common cause of dementia and represents the most prevalent neurodegenerative disease. For AD, disease-modifying treatments are presently lacking, and the understanding of disease mechanisms continues to be incomplete. In the present review, we discuss candidate contributing factors leading to AD, and evaluate novel computational brain simulation methods to further disentangle their potential roles. We first present an overview of existing computational models for AD that aim to provide a mechanistic understanding of the disease. Next, we outline the potential to link molecular aspects of neurodegeneration in AD with large-scale brain network modeling using The Virtual Brain (), an open-source, multiscale, whole-brain simulation neuroinformatics platform. Finally, we discuss how this methodological approach may contribute to the understanding, improved diagnostics, and treatment optimization of AD.

description: Litigation has long been a part of interest groups' lobbying tactics in the U.S. In Europe, by contrast, taking political conflicts to court has traditionally been viewed with skepticism. However, in the wake of an increasing judicialization of politics in Europe, litigation has also become part of the toolbox of European interest groups. Using original survey data from five European countries, we study how they use that tool. We show that European interest groups go to court somewhat less often than their American counterparts, but that the groups that do end up in court have similar characteristics. Overall, we find that the more politically active and resourceful a group is, the more likely it is to turn to the courts. However, a subset of politically active groups, one that deploys distinct outsider tactics, is more likely to use litigation than the rest. Government funding, however, reduces groups' propensity to litigate.
