description: A multitask deep neural network model was trained on more than 218k different glass compositions. This model, called GlassNet, can predict 85 different properties (such as optical, electrical, dielectric, mechanical, and thermal properties, as well as density, viscosity/relaxation, crystallization, surface tension, and liquidus temperature) of glasses and glass-forming liquids of different chemistries (such as oxides, chalcogenides, halides, and others). The model and the data used to train it are available in the GlassPy Python module as free and open source software for the community to use and build upon. As a proof of concept, GlassNet was used with the MYEGA viscosity equation to predict the temperature dependence of viscosity and outperformed another general purpose viscosity model available in the literature (ViscNet) on unseen data. An explainable AI algorithm (SHAP) was used to extract knowledge correlating the input (physicochemical information) and output (glass properties) of the model, providing valuable insights for glass manufacturing and design. It is hoped that GlassNet, with its free and open source nature, can be used to enable faster and better computer-aided design of new technological glasses.

Opportunities and Challenges of Modular Construction in a Hospitality Centric Environment
Creators: name: Paliwal, Shreyansh
Publisher: name: University of Nevada, Las Vegas
Year: 2019

description: Modular construction techniques can substantially decrease project schedules and costs, effectively maintaining or increasing the quality of an end product by shifting a percentage of site-based work to an off-site fabrication shop. Modular construction can also significantly contribute to sustainability by reducing site disruption, reducing waste generated, creating better relocatability and reusability, causing less dust and noise pollution, and reducing the probability of loss, theft, and damage to equipment. The primary goal of this research is to identify the opportunities and challenges of implementing modular construction techniques in a hospitality-centric environment, by investigating the current situation and characteristics of modular construction in Las Vegas. In this study, the approach includes the formulation of a survey, which was shared with 63 industry professionals, followed by three personal interviews. The results suggested that 85% percent of survey participants expected an improvement in schedule, and 65% of those actually experienced an improved schedule. Sixty-two percent of the participants claimed that they would continue using modular methods in the next 12 months, whereas, 44% claimed a plan to increase their use of modularization in the next 5 years. Two of the top five expected benefits achieved included reduced waste and less site disruption (noise/traffic, dust, etc.), which contribute towards sustainable construction. The results also demonstrated that transportation/logistics was selected by industry professionals as a key barrier in the implementation of modular construction. To implement more sustainable modular construction, practitioners require additional research to improve/overcome the key barrier of transportation/logistics. The results from this research would provide valuable insights for
implementing modular methods in hospitality-centric environments around the world, such as Paris, Macau, Singapore, Dubai, etc.
Effect of Common Oxidative Water Treatments on Acanthamoeba Internalized Legionella

description: Legionella pneumophila can cause pneumonic and non-pneumonic disease in humans. Infections occur from aerosolized contaminated water. This bacterium is an opportunistic intracellular pathogen able to infect both protozoans, such as Acanthamoeba polyphaga, and human macrophages. Both L. pneumophila and A. polyphaga resist commonly used water treatments, such as chlorination, but L. pneumophila has displayed greater resistance in the presence of A. polyphaga. Therefore, there is concern that L. pneumophila could become established in plumbing systems after water treatment, leading to infections. The objective of this study was to show the effect of chlorine and chlorine dioxide exposures on the survival of A. polyphaga internalized L. pneumophila. Gentamicin was used to kill extracellular L. pneumophila and samples were exposed to the oxidants, then the reactions were quenched and incubated at 30°C. The concentration of L. pneumophila was determined by culture analysis following lysis of Acanthamoeba on days 0, 7, and 14. Chlorine achieved ~1 log reduction at a concentration of 56.7 mg.min/L and ~2 log reduction at 376.3 mg.min/L. Chlorine dioxide achieved ~1 log reduction at a concentration of 74.21 mg.min/L and ~2 log reduction at 249.4 mg.min/L. All but one ClO2 concentration tested showed increasing log reduction throughout the 14-day monitoring period. This project addresses a concern of water treatment facilities and public health officials regarding the survival of intracellular Legionella. The results of this study show the need for greater understanding of other microorganisms' impact on Legionella control and will be useful to water treatment in determining oxidant levels needed for ensuring that potable water does not pose a delayed threat to the public.

description: The thermodynamics of excited nuclear systems allows one to explore the second-order phase transition in a two-component quantum mixture. Temperatures and densities are derived from quantum fluctuations of fermions. The pressures are determined from the grand partition function of Fisher's model. Critical scaling of observables is found for systems which differ in neutron to proton concentrations thus constraining the equation of state of asymmetric nuclear matter. The derived critical exponent β= 0.35 \pm 0.01, belongs to the liquid-gas universality class. The critical compressibility factor Pc /ρc Tc increases with increasing neutron number.

description: The BrainScaleS-2 (BSS-2) system implements physical models of neurons as well as synapses and aims for an energy-efficient and fast emulation of biological neurons. When replicating neuroscientific experiments on BSS-2, a major challenge is finding suitable model parameters. This study investigates the suitability of the sequential neural posterior estimation (SNPE) algorithm for parameterizing a multi-compartmental neuron model emulated on the BSS-2 analog neuromorphic system. The SNPE algorithm belongs to the class of simulation-based inference methods and estimates the posterior distribution of the model parameters; access to the posterior allows quantifying the confidence in parameter estimations and unveiling correlation between model parameters. For our multi-compartmental model, we show that the approximated posterior agrees with experimental observations and that the identified correlation between parameters fits theoretical expectations. Furthermore, as already shown for software simulations, the algorithm can deal with high-dimensional observations and parameter spaces when the data is generated by emulations on BSS-2. These results suggest that the SNPE algorithm is a promising approach for automating the parameterization and the analyzation of complex models, especially when dealing with characteristic properties of analog neuromorphic substrates, such as trial-to-trial variations or limited parameter ranges.

Die Wirkungen anderer Nachfrageprozesse auf die Lösung der verzögerten Differentialgleichung und damit des Peitscheneffektes sind zu untersuchen. Dementsprechend ist zu zeigen, dass der Nachfrageprozess des Typs „ Autoregressiver Prozess erster Ordnung “ (AR(1)) die Lösung der zugehörigen Differentialgleichung bestimmt und der Peitscheneffekt berechnet werden kann.

Oscillations following the Shubnikov-de Haas (SdH) formula are observed in the transition from the insulator to QH liquid when the observed almost temperature-independent Hall slope indicates insignificant interaction correction. Our study shows that the existence of SdH oscillations in such a transition can be understood based on the non-interacting model.

description: Modelle der neu-keynesianischen ¨Okonomie geben eine Erkl¨arung f¨ur die kurzfristige Nichtneutralit¨at des Geldes. Als Erkl¨arungsansatz dient hierbei die Annahme nominaler Rigidit¨aten auf dem Arbeits- und G¨utermarkt. Der vorliegende Beitrag zielt auf einen Vergleich zweier Modelle der neukeynesianischen Literatur. Zum einen wird das Modell von Fisher (1977) analysiert, zum anderen das Modell von Calvo (1983). Beide Modelle beruhen auf der Annahme der zeitlich gestaffelten Preissetzung (“Staggered Pricing“). Ein wesentlicher Unterschied zwischen beiden ist, dass das Fisher- Modell von einer festen Fixierung der Preise auf dem Arbeitsmarkt, d.h. der Nominall¨ohne ausgeht, das Calvo-Modell hingegen von einer stochastischen Fixierung der Preise auf dem G¨utermarkt. Im folgenden wird - im anschließenden Abschnitt 2, 3 und 4 - das Modell von Fisher (1977) und Calvo (1983) formal und verbal analysiert. Dabei wird im Abschnitt 4.2 das Verfahren der Dynamischen Programmierung erl¨autert, um im Rahmen des Modells von Calvo (1983) eine dynamische Analyse durchf¨uhren zu k¨onnen. Gegenstand des Abschnittes 5 ist ein Vergleich beider Modelle bez¨uglich der neu-keynesianischen Phillipskurve. Der Beitrag endet mit einer Zusammenfassung.

description: In this report, we present a concise review on the various moduli stabilisation schemes proposed in the context of type IIB superstring compactifications using Calabi-Yau orientifolds. We discuss the details of the known schemes by classifying them into two categories; the first one includes non-perturbative superpotential contributions leading to the well-known class of models like KKLT, Racetrack and LVS, while the second one includes only perturbative corrections arising from the series of $α^\prime$- and string-loop effects, leading to a new scheme - known as perturbative LVS. In addition, we motivate and briefly discuss about the global embedding requirements for all these moduli stabilisation schemes, and present some details for the perturbative LVS scheme by focusing on a concrete CY orientifold setting. In this context, the resulting 4D effective supergravity model indeed does not receive any non-pertubative superpotential effects due to the lack of necessary divisor topologies, and the Kähler moduli stabilisation is performed entirely by perturbative effects, leading to AdS minimum with exponentially large VEV for the overall volume of the internal CY manifold. It is further shown how this class of AdS solutions can be uplifted to de-Sitter solutions by using a couple of prescriptions such as $D$-term uplifting and the $T$-brane uplifting.

The Effects of Selective Doping on Electron Transport in Two-Dimensional Electron Gases

Publisher: name: California Institute of Technology
Year: 2006
Subjects: Physics

description: Recent research on bilayer two-dimensional electron gasses (2DEG) indicates the possibility of excitonic superfluidity, though experiments have measured small dissipation due to motion of unpaired vortices. In regular superconductors, carriers flow without dissipation beacuse vortices are "pinned" by impurities. This research investigates the effects of C and Si dopants within the quantum well of a single quantum well 2DEG. These dopants are candidates for improving vortex pinning in bilayer 2DEG systems. Four C-doped samples, with dopant density ranging from 3.5 x 1014cm-3 to 2.5 x 1016 cm-3 , and one Si-doped sample, with 2.3 x 1015m-3 Si ions are studied by electron transport measurements as functions of magnetic field strength. We find that minima in longitudinal resistance as a function of filling factor 11 are wider and offset toward'S lower v in samples with higher doping. This widening and shift is shown by mimina up to a v that decreases with increasing C dopant density, but is not observed at all for minima in the Si-doped sample.

description: We can feasibly probe for physics beyond the Standard Model of particle physics with more
accurate and precise results from neutron beta decay experiments. An ultracold neutron (UCN)
beta decay experiment will begin this year at the Los Alamos Neutron Science Center
(LANSCE). This experiment will perform a precision measurement of the neutron betaasymmetry
(or the A-correlation), which is the correlation between the neutron's spin and the
momentum of the emitted decay electron. A precise measurement of the A-correlation, combined
with a value for the neutron lifetime, can be used to test the unitarity of the Standard Model's
quark-electroweak mixing matrix. Prior to commencement, the 1 Tesla field superconducting
spectrometer constructed for the experiment by Caltech must be fully calibrated. A position and
energy resolution study of the plastic scintillator and MWPC was accomplished using thin film
conversion line sources, 113Sn and 207Bi, placed at the center of the spectrometer.

description: Diese Studie stellt die Ergebnisse einer Debattenanalyse zum Thema Rohstoffknappheit vor. Ziel dabei ist, die Debatte zu systematisieren, d.h. die Positionen zentraler Akteure zu charakterisieren und unterschiedliche Debattenstränge („Diskurse“) zu identifizieren. In diesem Problemfeld wurden drei Diskurse identifiziert: 1. ein wirtschaftlich/ökonomisch geprägter Versorgungssicherheits-Diskurs, der Konkurrenzsituationen um knapper werdende Ressourcen auf den internationalen Rohstoffmärkten betont und die Ausweitung des Rohstoffangebots als Lösungsansatz sieht; 2. einen entwicklungspolitischen Diskurs, der die Folgen von Rohstoffexporten aus rohstoffreichen Entwicklungsländern thematisiert und 3. einen rohstoffpolitischen Effizienz- Diskurs, der als Gegendiskurs zum Versorgungssicherheits-Diskurs von der Prämisse ausgeht, dass der inländische Ressourcenverbrauch als Stellschraube einer Rohstoffpolitik genutzt werden sollte um Abhängigkeiten von Rohstoffimporten zu verringern und negative soziale und ökologische Auswirkungen der Rohstoffgewinnung zu vermeiden. Zwischen diesen Diskursen gibt es Überschneidungen, beispielsweise im Bereich Recycling und Substitution oder bei der Bereitstellung einer besseren Informationsbasis über Ressourcenflüsse, aber auch Gegensätze. Diese zeigen nicht nur in der Problemdefinition und den Lösungsvorschlägen, sondern vor allem auch in der Instrumentierung einer Rohstoffpolitik. Vertreter des Versorgungssicherheits- Diskurses verweisen vor allem auf freiwillige Berichtsinitiativen und Förderprogramme für Investitionen in den Bergbau. Ordnungsrechtliche und fiskalische Instrumente lehnen sie dagegen strikt ab, weil sie vor allem an möglichst niedrigen Rohstoffpreisen interessiert sind. Demgegenüber sprechen sich Vertreter des Rohstoffeffizienz-Diskurses für die Nutzung ebensolcher Instrumente sowie für die Festlegung konkreter Verbrauchsobergrenzen aus.

description: Spike-timing-dependent plasticity (STDP) with asymmetric learning windows is commonly found in the brain and useful for a variety of spike-based computations such as input filtering and associative memory. A natural consequence of STDP is establishment of causality in the sense that a neuron learns to fire with a lag after specific presynaptic neurons have fired. The effect of STDP on synchrony is elusive because spike synchrony implies unitary spike events of different neurons rather than a causal delayed relationship between neurons. We explore how synchrony can be facilitated by STDP in oscillator networks with a pacemaker. We show that STDP with asymmetric learning windows leads to self-organization of feedforward networks starting from the pacemaker. As a result, STDP drastically facilitates frequency synchrony. Even though differences in spike times are lessened as a result of synaptic plasticity, the finite time lag remains so that perfect spike synchrony is not realized. In contrast to traditional mechanisms of large-scale synchrony based on mutual interaction of coupled neurons, the route to synchrony discovered here is enslavement of downstream neurons by upstream ones. Facilitation of such feedforward synchrony does not occur for STDP with symmetric learning windows.

description: A distinguishing feature among households is whether adult members work or not, since the employment status affects a household’s available time for home activities. Using a survey method in two countries, Belgium and Germany, we provide household incomes that retain the level of well-being across different family types, distinguished by family size and employment status of adults. Our tests support that specialization in home production and childcare-time costs are important determinants of household well-being. Estimates of child costs relative to an adult are higher for households that are time-constrained (all adults in the household work), and also higher for poorer households.

description: The paper discusses key elements of optimal central bank design and applies its findings to the Eurosystem. A particular focus is on the size of monetary policy committees, the degree of centralization, and the representation of relative economic size in the voting rights of regional (or sectoral) interests. Broad benchmarks for the optimal design of monetary policy committees are derived, combining relevant theoretical arguments with available empirical evidence. A new indicator compares the mismatch of relative regional economic size and voting rights in the monetary policy committees of the US Fed, the pre-1999 German Bundesbank, and the ECB over time. Based on these benchmarks, there seems to be room to improve the organization of the ECB Governing Board and current plans for reform.

description: In this work we study the dynamical properties of a finite array of nanomagnets in artificial kagome spin ice at room temperature. The dynamic response of the array of nanomagnets is studied by implementing a "frustrated celular autómata" (FCA), based in the charge model and dipolar model. The FCA simulations, allow us to study in real-time and deterministic way, the dynamic of the system, with minimal computational resource. The update function is defined according to the coordination number of vertices in the system. Our results show that for a set geometric parameters of the array of nanomagnets, the system exhibits high density of Dirac strings and high density emergent magnetic monopoles. A study of the effect of disorder in the arrangement of nanomagnets is incorporated in this work.
The allocation of authority under limited liability

Subjects: subject: authority

subject: 300 Sozialwissenschaften::330 Wirtschaft

description: Authority is modelled as the right to undertake a non-contractible decision in a joint project. We show that the allocation of authority depends on bargaining power and differences in both parties cost functions. The decision- maker is assumed to exert an externality on the other parties. Overall surplus is shared according to generalized Nash bargaining. Under limited liability, the agent with the larger cost parameter receives authority if the agents’ cost parameters are very different. If the agents have similar cost parameters, bargaining power determines the allocation of authority. Possible applications include the introduction of a new product.

The training group participated in a six-week DSB program consisting of weekly training sessions and at-home breathing exercises. DSB exercises focused on prolonging the exhalation and the pause following exhalation. The Western Ontario and McMaster Osteoarthritis Index (WOMAC) was used to assess pain and physical function and HRV data were obtained pre- and post-intervention. Results revealed no significant interactions between group and time for any of the variables. There was no significant main effect for group, but there was a significant main effect (p < 0.025) and a large effect size for time on both pain (training pre 148 ± 94, post 84 ± 89; control pre 123 ± 87, post 92 ± 73; group ηp2 = 0.003, time ηp2 = 0.454) and physical function (training pre 434 ± 268, post 276 ± 287; control pre 482 ± 346, post 338 ± 274; group ηp2 = 0.010, time ηp2 = 0.506). There were no significant main effects (p > 0.017) for group and time on LF power (training pre 179.30 ± 562.1 ms2, post 9.82 ± 28.84 ms2; control pre 32.08 ± 66.55 ms2, post 0.74 ± 0.73 ms2; group ηp2 = 0.039, time ηp2 = 0.061), HF power (training pre 14.04 ± 39.76 ms2, post 7.02 ± 19.24 ms2; control pre 7.43 ± 9.99 ms2, post 1.50 ± 1.87 ms2; group ηp2 = 0.039, time ηp2 = 0.039), and LF/HF ratio (training pre 5.64 ± 10.03, post 2.13 ± 3.72; control pre 2.38 ± 3.79, post 0.97 ± 0.69; group ηp2 = 0.036, time ηp2 = 0.169). Results indicated that the six-week DSB program was not sufficient to alleviate pain or improve physical function in subjects with lower extremity joint pain. As this is the first study to examine the use of DSB for lower extremity joint pain and dysfunction, further research is needed to investigate the efficacy and applicability of DSB.

description: In a monopoly setting where consumers cannot observe the quality of the product we show that free samples which are of a lower quality than the marketed digital goods are used together with high prices as signals for a superior quality if the number of informed consumers is small and if the di®erence between the high and the low quality is not too small. Social welfare is higher, if the monopolist uses also free samples as signals, compared to a situation where he is restricted to pure price signalling. Both, the monopolist and consumers bene¯t from the additional signal.

The political economy of the German Länder deficits

description: We analyze the deficits of the German Länder for the period from 1960 to 2000 and test a number of hypotheses derived from the literature on the political economy of public expenditures and public deficits. Estimating a dynamic panel data model, we find evidence for political opportunism of the Rogoff/Sibert- type. German voters seem to favor fiscal discipline as debt issue is significantly lower in pre-election years. There is no evidence for partisan behavior. Party ideology thus plays a negligible role. As suggested by the theory, coalition governments issue more debt. This effect is, however, not statistically significant. If the probability of reelection is small, the incumbent government may find it beneficial to issue more debt. We consider four different approximations of the reelection probability but find evidence for none of them.

Intrinsic surface superconducting instability in Type-I Weyl Semimetals

description: Recent experiments on non-magnetic Weyl semimetals have seen separate bulk and surface superconductivity in Weyl semimetals, which raises the question of whether the surface Fermi arcs can support intrinsic superconductivity while the bulk stays in the normal state. A theoretical answer to this question is hindered by the absence of a well-defined surface Hamiltonian since the Fermi arcs merge with the bulk states at their endpoints. Using an alternate, Green's functions-based approach on a phenomenological model that can yield arbitrary Fermi arcs, we show -- within mean-field theory -- that the surface can support a standard Cooper instability while the bulk remains disordered. Although the surface has lower dimensionality, a higher density of states compared to the bulk allows it to have a higher mean-field superconducting transition temperature.

description: The ground state energies of Ag and Au in the face-centered cubic (FCC), body-centered cubic (BCC), simple cubic (SC) and the hypothetical diamond-like phase, and dimer were calculated as a function of bond length using density functional theory (DFT). These energies were then used to parameterize the many-body Gupta potential for Ag and Au. This parameterization over several phases of Ag and Au was performed to guarantee transferability of the potentials and to make them appropriate for studies of related nanostructures. Depending on the structure, the energetics of the surface atoms play a crucial role in determining the details of the nanostructure. The accuracy of the parameters was tested by performing a 2 ns MD simulation of a cluster of 55 Ag atoms -- a well studied cluster of Ag, the most stable structure being the icosahedral one. Within this time scale, the initial FCC lattice was found to transform to the icosahedral structure at room temperature. The new set of parameters for Ag was then used in a temperature dependent atom-by-atom deposition of Ag nanoclusters of up to 1000 atoms. We find a deposition temperature of 500 $\pm$50 K where low energy clusters are generated, suggesting an optimal annealing temperature of 500 K for Ag cluster synthesis.

description: This paper explores the pre-First World War Austro-Hungarian economy as a prominent case where growing conflict between various ethnic and national groups within an empire might have contributed to the emergence of internal borders and even its eventual dissolution. To this end we adopt an Engel-and- Rogers–type approach to examine on an annual basis the extent of co-movements in grain prices across a sample of ten regional capital cities in the empire and over the period 1877-1910. There are two key findings. First, the political borders that emerged from 1918 onwards became visible in the price dynamics of grain markets already 20 years before the Great War. Second, this effect of a “border before a border” can be explained by the extent of language heterogeneity across the various parts of the Habsburg Empire. These results raise several important questions about both the forces that shaped pre-war market integration as well as the economic costs of breaking up the Habsburg customs union after 1918.

description: Since objective news coverage is vital to democracy, captured media can seriously distort collective decisions. The current paper develops a voting model where citizens are uncertain about the welfare e¤ects induced by alternative policy options and derive information about those e¤ects from the mass media. The media might however secretly collude with interest groups in order to in uence the public opinion. In the case of voting over the level of a productivity-enhancing public bad, it is shown that an increase in the concentration of rm ownership makes the occurrence of media bias more likely. Although media bias is not always welfare worsening, conditions for it to raise welfare are restrictive.

description: The question of the correlation between magnetization, band splittings, and magnetic circular dichroism (MCD) in the fundamental gap region of dilute magnetic semiconductors is examined experimentally and theoretically taking the case of wurtzite Ga(1-x)FexN as an example. Magnetization and polarization-resolved reflectivity measurements have been performed down to 2K and up to 7T for x = 0.2%. Optical transitions originating from all three free excitons A, B and C, specific to the wurtzite structure, have been observed and their evolution with the magnetic field determined. It is demonstrated that the magnitude of the exciton splittings evaluated from reflectivity-MCD data can be overestimated by more than a factor of 2, as compared to the values obtained by describing the polarization-resolved reflectivity spectra with appropriate dielectric functions. A series of model calculations shows that the quantitative inaccuracy of MCD originates from a substantial influence of the magnetization-dependent exchange interactions not only on the spin splittings of excitons but also upon their linewidth and oscillator strength. At the same time, a method is proposed that allows to evaluate the field and temperature dependencies of the magnetization from MCD spectra. The accurate values of the excitonic splittings and of the magnetization reported here substantiate the magnitudes of the apparent $sp-d$ exchange integrals in (Ga,Fe)N previously determined.

description: Accurate perception of objects in the environment is important for improving the scene understanding capability of SLAM systems. In robotic and augmented reality applications, object maps with semantic and metric information show attractive advantages. In this paper, we present RO-MAP, a novel multi-object mapping pipeline that does not rely on 3D priors. Given only monocular input, we use neural radiance fields to represent objects and couple them with a lightweight object SLAM based on multi-view geometry, to simultaneously localize objects and implicitly learn their dense geometry. We create separate implicit models for each detected object and train them dynamically and in parallel as new observations are added. Experiments on synthetic and real-world datasets demonstrate that our method can generate semantic object map with shape reconstruction, and be competitive with offline methods while achieving real-time performance (25Hz).
