Continuum model of the simple dielectric fluid: Consistency between density based and continuum mechanics methods
Creators: name: Sprik, Michiel
Publisher: name: arXiv
Year: 2020
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: The basic continuum model for polar fluids is deceptively simple. The free energy integral consists of four terms: The coupling of polarization to an external field, the electrostatic energy of the induced electric field interacting with itself and the stored polarization energy quadratic in the polarization. A local function of density accounts for the mechanical state of the fluid. Viewed as a non-equilibrium free energy functional of number density and polarization, minimization in these two densities under constraints of the Maxwell field equations should lead the correct equilibrium state. The alternative is a continuum mechanics approach in which the mechanical degree of freedom is extended to full deformation. We show that the continuum electromechanics method leads to a force balance equation which is consistent with the density functional equilibrium equation. The continuum mechanics procedure is significantly more demanding. The gain is a well defined pressure tensor derived from deformation of total energy. This resolves the issue of the uncertainty in the pressure tensor obtained from integration of the force density, which is the conventional method in density based thermomechanics. Our derivation is based on the variational electrostatics approach developed by Ericksen (Arch. Rational Mech. Anal. {\bf 183} 299 (2007)).

description: This paper studies the effects of high skilled immigration on employment and net income in the host economy where the market for low skilled labor is distorted by union wage setting and a redistributive unemployment benefit scheme. I show that high skilled immigration can increase as well as decrease low skilled employment depending on how the public budget adjusts to immigration and that the effects on workers' net income levels may vary substantially. I conclude that a Pareto improvement can be achieved if the unemployment benefit level remains unaffected by high skilled immigration.

description: We construct Matrix Membrane theory in pp wave backgrounds that have a null linear dilaton in Type IIB string theory. Such backgrounds can serve as toy models of big bang cosmologies. At late times only abelian degrees of freedom survive, and if the Kaluza-Klein modes along one of the directions of the membrane decouple, standard perturbative strings emerge. Near the ``big bang'', non-abelian configurations of fuzzy ellipsoids are present, as in the Type IIA theories. A generic configuration of these shrink to zero volume at late times. However, the Kaluza Klein modes (which can be thought of as states of (p,q) strings in the original IIB theory) can be generically produced in pairs in both pp wave and flat backgrounds in the presence of time dependence. Indeed, if we require that at late times the theory evolves to the perturbative string vacuum, these modes must be prepared in a squeezed state with a thermal distribution at early times.

description: All protein structures submitted to the Protein Data Bank (PDB) are validated to identify potential errors and quantify their overall quality. Validation can be broadly categorised into two types: “geometric” and “model vs data”. Geometric validation asks whether a protein structure looks like what we know proteins generally look like. A structure may have very good geometrical quality but this does not necessarily mean it is accurate (an accurate structure is one that is close to the true structure). In order to determine accuracy, model vs data validation is required. For x-ray crystal structures, model vs data measures include R factor and Rfree. However, for NMR structures there are no equivalent measures and therefore no method for determining their accuracy.

We are currently developing a method for validating the accuracy of NMR protein structures which involves computing local flexibility (i.e. per residue) using Floppy Inclusions and Rigid Substructure Topography (FIRST) to compare to local flexibility predicted from backbone chemical shifts using Random Coil Index RCI. We present our progress so far, including how our method can identify structures that have incorrect fold/secondary structure and structures that are too floppy (e.g. lack sufficient hydrogen bonds).

description: We consider two-level detectors coupled to a scalar field and moving on arbitrary trajectories in Minkowski space-time. We first derive a generic expression for the response function using a (novel) regularization procedure based on the Feynmann prescription that is explicitly causal, and we compare it to other expressions used in the literature. We then use this expression to study, analytically and numerically, the time dependence of the response function in various non-stationarity situations. We show that, generically, the response function decreases like a power in the detector's level spacing, $E$, for high $E$. It is only for stationary world-lines that the response function decays faster than any power-law, in keeping with the known exponential behavior for some stationary cases. Under some conditions the (time dependent) response function for a non-stationary world-line is well approximated by the value of the response function for a stationary world-line having the same instantaneous acceleration, torsion, and hyper-torsion. While we cannot offer general conditions for this to apply, we discuss special cases; in particular, the low energy limit for linear space trajectories.

monetary policy regime, regional inflation

description: The adoption of a credible monetary policy regime such as inflation
targeting is known to reduce the persistence of inflation fluctuations. This conclusion, however, is derived from aggregate inflation or sectoral inflation rates, not from regional inflation data. This paper studies the regional dimension of inflation targeting, i.e. the consequences of inflation targeting for regional inflation persistence. Based on data for Korean cities and provinces it is shown that the adoption of inflation targeting leads (i) to a fall in inflation persistence at the regional level and (ii) to a reduction in the cross-regional heterogeneity in inflation persistence. A common factor model lends further support to the role of the common component, and hence monetary policy, for regional inflation persistence.

description: Tor and i2p networks are two of the most popular darknets. Both darknets have become an area of illegal activities highlighting the necessity to study and analyze them to identify and report illegal content to Law Enforcement Agencies (LEAs). This paper analyzes the connections between the Tor network and the i2p network. We created the first dataset that combines information from Tor and i2p networks. The dataset contains more than 49k darknet services. The process of building and analyzing the dataset shows that it is not possible to explore one of the networks without considering the other. Both networks work as an ecosystem and there are clear paths between them. Using graph analysis, we also identified the most relevant domains, the prominent types of services in each network, and their relations. Findings are relevant to LEAs and researchers aiming to crawl and investigate i2p and Tor networks.

description: We discuss head-on collisions of neutron stars and disks of dust ("galaxies") following the ideas of equilibrium thermodynamics, which compares equilibrium states and avoids the description of the dynamical transition processes between them. As an always present damping mechanism, gravitational emission results in final equilibrium states after the collision. In this paper we calculate selected final configurations from initial data of colliding stars and disks by making use of conservation laws and solving the Einstein equations. Comparing initial and final states, we can decide for which initial parameters two colliding neutron stars (non-rotating Fermi gas models) merge into a single neutron star and two rigidly rotating disks form again a final (differentially rotating) disk of dust. For the neutron star collision we find a maximal energy loss due to outgoing gravitational radiation of 2.3% of the initial mass while the corresponding efficiency for colliding disks has the much larger limit of 23.8%.

DSGE model
Inventories

description: This paper introduces inventories in an otherwise standard Dynamic Stochastic General Equilibrium Model (DSGE) of the business cycle. Firms accumulate inventories to facilitate sales, but face a cost of doing so in terms of costly storage of intermediate goods. The paper’s main contribution is to present a DSGE model with inventories that is estimated using Bayesian methods. Based on U.S. data we show that accounting for inventory dynamics has a significant impact on parameter estimates and impulse responses. Our analysis also reveals that the contribution of structural shocks to variations in the observable variables changes significantly when we allow for inventories. Moreover, we find that inventories enter the Phillips curve as an additional and significant driving variable of inflation and make the inflation process less backward-looking.
title: Serum albumin as a measure of inflammation or malnutrition in inflammatory bowel disease: a cross sectional study
Creators: name: Squirell, Elizabeth
Publisher: name: Memorial University of Newfoundland
Year: 2021

description: Albumin may be both a marker of malnutrition and a marker of inflammation in various disease states but there has been very little study of the precise etiology of hypoalbuminemia in patients with Crohn’s disease (CD). Malnutrition, a common complication of active CD, can lead to hypoalbuminemia. Inflammation can also lead to low albumin levels, and previous literature in other inflammatory diseases has suggested that inflammation may be more likely than malnutrition to be a primary driver of hypoalbuminemia. This study was a single centre cross sectional study of patients with Crohn’s disease in St. John’s, NL. The main objectives were to examine the association between serum albumin and both inflammation and malnutrition in patients with CD and to determine if serum albumin is an appropriate indicator of one or both of these processes in patients with CD. A total of 45 patients with Crohn’s disease were enrolled in the study. Serum albumin was compared with the subjective global assessment (SGA) for nutritional status, the Crohn’s disease activity index (CDAI), and CReactive Protein (CRP), a marker of inflammation. In our study hypoalbuminemia was independently associated with both malnutrition and inflammation in patients with CD but was most profound in subjects with both malnutrition and active inflammation.

identification through heteroscedasticity

description: This paper formally proves that Rigobon and Sack (2004)'s approach of identifying monetary policy shocks through heteroscedasticity can be extended to a multimarket and multicountry framework. Applying our multivariate framework allows deriving consistent estimators of monetary policy effects. The advantage of our extended approach is illustrated by applying it to European financial markets. We analyse monetary policy actions of the European Central Bank (ECB), the Bank of England, the Swiss National Bank, and the Swedish Riksbank on major stock indices. First, in line with the Rigobon and Sack (2004) approach, we find an increase in the variance of European stock and money market returns on days when monetary policy committee meetings are held. Second, monetary policy actions have a significant impact on financial markets. Third, we discover that ECB monetary policy moves have spillover effects on the British and Swiss financial markets, but find no evidence of reverse causality.
Particle redistribution and slow decay of correlations in hard-core fluids on a half-driven ladder

description: We study driven particle systems with excluded volume interactions on a two-lane ladder with periodic boundaries, using Monte Carlo simulation, cluster mean-field theory, and numerical solution of the master equation. Particles in one lane are subject to a drive that forbids motion along one direction, while in the other lane the motion is unbiased; particles may jump between lanes. Despite the symmetry of the rates for transitions between lanes, the associated particle densities are unequal: at low densities there is an excess of particles in the undriven lane, while at higher densities the tendency is reversed. Similar results are found for an off-lattice model. We quantify the reduction in the stationary entropy caused by the drive. The stationary two-point correlation functions are found to decay algebraically, both on- and off-lattice. In the latter case the exponent governing the decay varies continuously with the density.

description: By extending a typical endowment effect experiment with the possibility to win the endow-ment in a real effort contest, we found two enforcing effects that led to a complete market failure. Subjects who won the item in the competition had an extremely high willingness to accept (trophy effect). By contrast, subjects who were not successful had an extremely low willingness to pay for the same item (reverse trophy effect). We disentangle the different components of the trophy effect, compare it to similar experiments, and discuss its important economic implications.

description: L’objectif principal visé par cette banque de données est de permettre l’accès contrôlé et sécurisé aux images médicales (incluant les images de pathologie) acquises dans un contexte clinique ou de recherche. L’accès physique aux fichiers d’imagerie devient nécessaire pour un nombre grandissant d’usages, notamment en radiomique, en intelligence artificielle et à des fins clinico-administratives (par ex. portrait des doses administrées en radiologie diagnostique). Sans cadre de gestion dédié, ces accès peuvent mener à des efforts dupliqués, à des bris de confidentialité et à des résultats peu ou pas reproductibles. La banque et les services y étant reliés (par ex. dé-identification, opérations en lot) visent à remplacer des processus actuels qui reposent principalement sur la production de CD/DVD par les filmothèques, et à implanterde bonnes pratiques quant à la gestion des images et aux flux de travail associés. Les images proviendront de différents secteurs dont la radiologie, la radio-oncologie, la médecine nucléaire et la pathologie, depuis des installations du réseau public ou de cliniques privées. Un deuxième objectif de la banque est de préserver dans un format normalisé l’information qui est générée lorsque les images sont annotées par des spécialistes ou par des agents machines (par ex. segmentation par une radiologiste ou un algorithme). Ces informations, qui peuvent être qualifiées de coûteuses (en expertise ou en temps de calcul), viennent bonifier substantiellement les données brutes etaugmentent leur potentiel de valorisation. À cet égard, la banque de données soutient les activités de curation liées à l’imagerie médicale et s’inscrit dans une volonté de rendre ces données FAIR (Facilement repérables, Accessibles, Interopérables, Réutilisables) en adéquation avec la Politique des trois organismes (CRSH, IRSC, CRSNG) sur la gestion des données de recherche. Il est important de souligner que le caractère FAIR des données n’a pas d’impact sur leur nature confidentielle; les obligations éthiques, légales et réglementaires sur les renseignements personnels continuent d’être respectées.

description: In this paper we apply second-order gauge-invariant perturbation theory to investigate the possibility that the non-linear coupling between gravitational waves (GW) and a large scale inhomogeneous magnetic field acts as an amplification mechanism in an `almost' Friedmann-Lemaitre-Robertson-Walker (FLRW) Universe. The spatial inhomogeneities in the magnetic field are consistently implemented using the magnetohydrodynamic (MHD) approximation, which yields an additional source term due to the interaction of the magnetic field with velocity perturbations in the plasma. Comparing the solutions with the corresponding results in our previous work indicates that, on super-horizon scales, the interaction with the spatially inhomogeneous field in the dust regime induces the same boost as the case of a homogeneous field, at least in the ideal MHD approximation. This is attributed to the observation that the MHD induced part of the generated field effectively only contributes on scales where the coherence length of the initial field is less than the Hubble scale. At sub-horizon scales, the GW induced magnetic field is completely negligible in relation to the MHD induced field. Moreover, there is no amplification found in the long-wavelength limit.

We show the impact of nonlocality on the domains of existence and stability of the surface solitons, focusing on new types of dipole solitons residing partially inside the optical lattice. We find that such solitons feature strongly asymmetric shapes and that they are stable in large parts of their existence domain.

Finite-amplitude method for collective inertia in spontaneous fission

description: Background: Microscopic description of spontaneous fission is one of the most challenging subjects in nuclear physics. It is necessary to evaluate the collective potential and the collective inertia along a fission path for a description of quantum tunneling in spontaneous or low-energy fission. In past studies of the fission dynamics based on nuclear energy density functional (EDF) theory, the collective inertia has been evaluated with the cranking approximation, which neglects dynamical residual effects. Purpose: The purpose is to provide a reliable and efficient method to include dynamical residual effects in the collective inertia for fission dynamics. Methods: We use the local quasiparticle random-phase approximation (LQRPA) to evaluate the collective inertia along a fission path obtained by the constrained Hartree-Fock-Bogoliubov method with the Skyrme EDF. The finite-amplitude method (FAM) with a contour integration technique enables us to efficiently compute the collective inertia in a large model space. Results: We evaluate the FAM-QRPA collective inertia along a symmetric fission path in $^{240}$Pu and $^{256}$Fm. The FAM-QRPA inertia is significantly larger than the one of the cranking approximation, and shows pronounced peaks around the ground state and the fission isomer. This is due to dynamical residual effects. Conclusions: To describe the spontaneous or low-energy fission, we provide a reliable and efficient method to construct the collective inertia with dynamical residual effects that have been neglected in most of EDF-based works in the past. We show the importance of dynamical residual effects to the collective inertia. This work will be a starting point for a systematic study of fission dynamics in heavy and superheavy nuclei to microscopically describe the nuclear large-amplitude collective motions.

description: Economic page turners like Freakonomics are well written and there is much to be learned from them – not only about economics, but also about writing techniques. Their authors know how to build up suspense, i.e., they make readers want to know what comes. An uncountable number of pages in books and magazines are filled with advice on writing reportages or suspense novels. While many of the tips are specific to the respective genres, some carry over to economic page turners in an instructive way. After introducing some of these writing tools, I discuss whether these and other aspects of good writing lead to a biased presentation of economic theory and practice. I conclude that, whatever the problems with certain economic page turners may be, they are not due to the need to write in an accessible, appealing way.

By extrapolating to zero pressure, we have deduced the Doppler width which gives a first measurement of the Boltzmann constant, kB, by laser spectroscopy. A relative uncertainty of 2x10-4 has been obtained. The present determination should be significantly improved in the near future and contribute to a new definition of the kelvin.

Based on a new data set of forecasts from individual FOMC members between 1992 and 2000 it is shown that FOMC members intentionally overrevise their forecasts at the first revision and underrevise at the final revision date. This pattern of rationally biased forecasts is similar to that of private sector forecasters and is consistent with theories of reputation building among forecasters. The FOMC’s shift towards more transparency in 1994 had an impact on how members revised their forecasts and intensified the tendency to underrevise at the later stage of the forecasting process. The tendency to underrevise, i.e. to smooth forecast revisions, is particularly strong for nonvoting members of the committee.

description: In recent years, advances in the development of whole-slide images have laid a foundation for the utilization of digital images in pathology. With the assistance of computer images analysis that automatically identifies tissue or cell types, they have greatly improved the histopathologic interpretation and diagnosis accuracy. In this paper, the Convolutional Neutral Network (CNN) has been adapted to predict and classify lymph node metastasis in breast cancer. Unlike traditional image cropping methods that are only suitable for large resolution images, we propose a novel data augmentation method named Random Center Cropping (RCC) to facilitate small resolution images. RCC enriches the datasets while retaining the image resolution and the center area of images. In addition, we reduce the downsampling scale of the network to further facilitate small resolution images better. Moreover, Attention and Feature Fusion (FF) mechanisms are employed to improve the semantic information of images. Experiments demonstrate that our methods boost performances of basic CNN architectures. And the best-performed method achieves an accuracy of 97.96% and an AUC of 99.68% on RPCam datasets, respectively.

monetary policy reaction function

description: We estimate monetary policy reaction functions with threshold effects for the Deutsche Bundesbank using a real-time data set. Estimates based on the deviation of inflation from the Bundesbank’s inflation target as threshold variable suggest a switch to a stronger output gap response in the reaction function if past inflation was high. The reaction function in the regime with higher inflation implies an overall less contractionary monetary policy than that for the low inflation regime. A modified model with three regimes shows this result to be related to periods of substantial excess inflation. We explore a threshold reaction function with a moving inflation target that captures a gradual adjustment of an intermediate to a long-term inflation target and find the Bundesbank to follow a more restrictive monetary policy stance if inflation is above the intermediate-term inflation target.

Sustainability stock indexes

description: This paper empirically analyzes the effect of the inclusion of German corporations in the Dow Jones STOXX Sustainability Index (DJSI STOXX) and the Dow Jones Sustainability World Index (DJSI World) on stock performance. In order to receive robust estimation results, we apply an event study approach that is based on both a modern asset pricing model, namely the three-factor model according to Fama and French (1993), and additionally on a GARCH model. Our empirical analysis implies that stock markets may penalize the inclusion of a firm in sustainability stock indexes. This result is mainly driven by the negative effect of the inclu-sion in the DJSI World. While we do not find significant average cumulative abnormal returns for the inclusion in the DJSI STOXX, the inclusion in the DJSI World leads to strong nega-tive impacts. This suggests that the inclusion in a more visible sustainability stock index has larger negative impacts.

description: Diese Masterarbeit untersucht das Potenzial von ChatGPT im Innovationsprozess von Unternehmen. Ziel der Untersuchung ist es herauszufinden, wie ChatGPT Führungskräfte und Mitarbeiter unterstützen kann, um Kreativität, Effizienz, Entscheidungsfindung und Kosteneffizienz in verschiedenen Phasen der Innovation zu optimieren. Hierzu wurde ein Mixed-Methods-Ansatz gewählt, der quantitative Umfragen und qualitative Interviews mit Branchenexperten kombiniert.

Die Ergebnisse zeigen, dass ChatGPT besonders in den Phasen der Ideenfindung und Konzeptentwicklung signifikante Vorteile bietet. Es unterstützt die Generierung kreativer Ideen und die Verfeinerung bestehender Konzepte. In den späteren Phasen des Innovationsprozesses trägt ChatGPT zur Entscheidungsfindung und Problemlösung bei, indem es umfangreiche Datenanalysen und Trendprognosen bereitstellt. Weiter berichten Unternehmen von einer erhöhten Effizienz, gesteigerter Kreativität und verbesserten Entscheidungsqualität durch die Nutzung von ChatGPT. Zudem trägt der Einsatz des Chatbots zur Kosteneffizienz bei, da Zeit- und Ressourcenaufwände reduziert werden.

Die Arbeit identifiziert mehrere spezifische Vorteile von ChatGPT: Es erleichtert ungeraderem Brainstorming-Sitzungen durch kontinuierliche Generierung neuer Ideen und Denkanstösse und hilft grosse Datenmengen zu analysieren, um Trends und Muster zu erkennen. Dies unterstützt Unternehmen innovative Ideen zu entwickeln, die den aktuellen Marktanforderungen entsprechen. Ferner fördert es die Entwicklung kreativer Lösungen und fungiert als Sparringspartner, indem es Fragen stellt und verschiedene Perspektiven einbringt.
Trotz dieser Vorteile bestehen auch Herausforderungen bei der Integration von ChatGPT. Dazu gehören die Akzeptanz durch die Nutzer, Probleme bei der Skalierbarkeit sowie ethische Bedenken hinsichtlich Datenschutzes und verantwortungsbewusster Nutzung von KI. Die Arbeit empfiehlt daher die Implementierung umfassender Schulungsprogramme, Investitionen in skalierbare Infrastrukturen und die Entwicklung ethischer Richtlinien, um diese Herausforderungen zu adressieren.

Zusammenfassend zeigt die Arbeit, dass ChatGPT das Potenzial hat, den Innovationsprozess in Unternehmen signifikant zu verbessern, sofern die Implementierung strategisch erfolgt und die genannten Herausforderungen berücksichtigt werden. Die Forschung unterstreicht die Bedeutung von ChatGPT als wertvolles Werkzeug zur Förderung von Innovationen und bietet konkrete Empfehlungen für dessen erfolgreiche Anwendung in der Praxis.

description: Thermoelectric (TE) refrigeration such as Peltier cooler enables a unique opportunity in electric energy to directly convert thermal energy. Here, we propose a TE module with both refrigeration and power generation modes by utilizing asymmetric surfaces of a magnetic topological insulator (quantum anomalous Hall insulator) with a periodic array of hollows filled with two different dielectrics. Based on the Boltzmann transport theory, we show that its efficiency, i.e., the dimensionless figure of merit ZT exceeds 1 in the low-temperature regime below 300 K. The proposed device could be utilized as a heat management device that requires precise temperature control in small-scale cooling.

description: The Equation of State and the properties of matter in the high temperature deconfined phase are analyzed by a quasiparticle approach for $T> 1.2~T_c$. In order to fix the parameters of our model we employ the lattice QCD data of energy density and pressure. First we consider the pure SU(3) gluon plasma and it turns out that such a system can be described in terms of a gluon condensate and of gluonic quasiparticles whose effective number of degrees of freedom and mass decrease with increasing temperature. Then we analyze QCD with finite quark masses. In this case the numerical lattice data for energy density and pressure can be fitted assuming that the system consists of a mixture of gluon quasiparticles, fermion quasiparticles, boson correlated pairs (corresponding to in-medium mesonic states) and gluon condensate. We find that the effective number of boson degrees of freedom and the in-medium fermion masses decrease with increasing temperature. At $T \simeq 1.5 ~T_c$ only the correlated pairs corresponding to the mesonic nonet survive and they completely disappear at $T \simeq 2 ~T_c$. The temperature dependence of the velocity of sound of the various quasiparticles, the effects of the breaking of conformal invariance and the thermodynamic consistency are discussed in detail.

description: Graph-structured data are an integral part of many application domains, including chemoinformatics, computational biology, neuroimaging, and social network analysis. Over the last two decades, numerous graph kernels, i.e. kernel functions between graphs, have been proposed to solve the problem of assessing the similarity between graphs, thereby making it possible to perform predictions in both classification and regression settings. This manuscript provides a review of existing graph kernels, their applications, software plus data resources, and an empirical comparison of state-of-the-art graph kernels.

Relation between phase space coverage and entanglement for spin-1/2 systems

description: For systems of two and three spins 1/2 it is known that the second moment of the Husimi function can be related to entanglement properties of the corresponding states. Here, we generalize this relation to an arbitrary number of spins in a pure state. It is shown that the second moment of the Husimi function can be expressed in terms of the lengths of the concurrence vectors for all possible partitions of the N-spin system in two subsystems. This relation implies that the phase space distribution of an entangled state is less localized than that of a non-entangled state. As an example, the second moment of the Husimi function is analyzed for an Ising chain subject to a magnetic field perpendicular to the chain axis.

description: One way of evaluating how well monetary authorities perform is to provide the public with a regular and independent second opinion. The European Central Bank (ECB) and the Bank of England are shadowed by professional and academic economists who provide a separate policy rate recommendation in advance of the central bank announcement. We explore differences between shadow and actual committee decisions based on an adapted Taylor rule and report a few systematic differences. The shadow committee of the ECB tends to be relatively less inflation averse than the ECB’s Governing Council. Perhaps most significantly our interpretation of the stance of the shadow committees is sensitive to the use of real time data, especially during the global financial crisis.
