description: We give a generalization to an infinite tree geometry of Vidal's infinite time-evolving block decimation (iTEBD) algorithm for simulating an infinite line of quantum spins. We numerically investigate the quantum Ising model in a transverse field on the Bethe lattice using the Matrix Product State ansatz. We observe a second order phase transition, with certain key differences from the transverse field Ising model on an infinite spin chain. We also investigate a transverse field Ising model with a specific longitudinal field. When the transverse field is turned off, this model has a highly degenerate ground state as opposed to the pure Ising model whose ground state is only doubly degenerate.

description: While measures can be taken to reduce the number of large-scale power losses due to failures of the generation and high-voltage transmission grid, such failures cannot be eliminated. The survival of essential missions is a more tractable problem than the prevention of all large cascading failures, and its solutions are verifiable. Thus, serious attention should be directed towards assuring the continuation of essential missions even after the grid has failed.

description: The ability to detect and distinguish quantum interference signatures is important for both fundamental research and for the realization of devices including electron resonators, interferometers and interference-based spin filters. Consistent with the principles of subwavelength optics, the wave nature of electrons can give rise to various types of interference effects, such as Fabry-Pérot resonances, Fano resonances and the Aharonov-Bohm effect. Quantum-interference conductance oscillations have indeed been predicted for multiwall carbon nanotube shuttles and telescopes, and arise from atomic-scale displacements between the inner and outer tubes. Previous theoretical work on graphene bilayers indicates that these systems may display similar interference features as a function of the relative position of the two sheets. Experimental verification is, however, still lacking. Graphene nanoconstrictions represent an ideal model system to study quantum transport phenomena due to the electronic coherence and the transverse confinement of the carriers. Here, we demonstrate the fabrication of bowtie-shaped nanoconstrictions with mechanically controlled break junctions (MCBJs) made from a single layer of graphene. We find that their electrical conductance displays pronounced oscillations at room temperature, with amplitudes that modulate over an order of magnitude as a function of sub-nanometer displacements. Surprisingly, the oscillations exhibit a period larger than the graphene lattice constant. Charge-transport calculations show that the periodicity originates from a combination of quantum-interference and lattice-commensuration effects of two graphene layers that slide across each other. Our results provide direct experimental observation of Fabry-Pérot-like interference of electron waves that are partially reflected/transmitted at the edges of the graphene bilayer overlap region.

description: Planetary systems with several planets in compact orbital configurations such as TRAPPIST-1 are surely affected by tidal effects. Its study provides us with important insight about its evolution. We developed a second generation of a N-body code based on the tidal model used in Mercury-T, re-implementing and improving its functionalities using Rust as programming language (including a Python interface for easy use) and the WHFAST integrator. The new open source code ensures memory safety, reproducibility of numerical N-body experiments, it improves the spin integration compared to Mercury-T and allows to take into account a new prescription for the dissipation of tidal inertial waves in the convective envelope of stars. Posidonius is also suitable for binary system simulations with evolving stars.

The FFLO state in the one-dimensional attractive Hubbard model and its fingerprint in the spatial noise correlations

description: We explore the pairing properties of the one-dimensional attractive Hubbard model in the presence of finite spin polarization. The correlation exponents for the most important fluctuations are determined as a function of the density and the polarization. We find that in a system with spin population imbalance, Fulde-Ferrell-Larkin-Ovchinnikov (FFLO)-type pairing at wavevector Q=|k_{F,\uparrow}-k_{F,\downarrow}| is always dominant and there is no Chandrasekhar-Clogston limit. We then investigate the case of weakly coupled 1D systems and determine the region of stability of the 1D FFLO phase. This picture is corroborated by density-matrix-renormalization-group (DMRG) simulations of the spatial noise correlations in uniform and trapped systems, unambiguously revealing the presence of fermion pairs with nonzero momentum Q. This opens up an interesting possibility for experimental studies of FFLO states.

description: The contribution of technological innovations to design choices, like in many industrial sectors, does not always correspond to controlled improvement of the built environment. Integrating feedback from the physical and cultural context of construction is a challenge for the future of the profession. International studies dedicate resources in order to monitor constructions and to develop executive designs that are evidence-based. Professional associations, research institutes and universities experiment with models for integrating specialist skills into a commitment that is unsustainable for most architects. Based on these experiences, this contribution considers an informed and reliable process of ideation-construction in pursuit of build quality.

The additional heavy particles ($t$, $W$, $Z$) in the final state can be used for tagging purposes, increasing the signal to background ratio. These reactions are dominated by $bq$ and $bg$ fusion. Their relevance for Higgs particle searches is discussed taking into account the expected efficiencies and purities for $b$--tagging. We find that, for tan$β= 30$, the cross sections for $pp\rightarrow bZ^0Φ$ are larger than 14 $pb$, over the whole intemediate range of $M_{A^0}$, for $A^0$ and at least one of the other two Higgses. Therefore this reaction is an excellent candidate for the discovery of one or more $\cal MSSM$ Higgs particles.}

Capital Ownership under Market Incompleteness: Does It Matter?

description: In the macroeconomic literature, the implications of a context with household heterogeneity and incomplete financial markets have been mostly studied under the assumption that households own the physical capital and undertake the intertemporal investment decision. Further, firms rent capital and labor from the households to maximize period profits. The present paper provides the conditions under which this assumption is still irrelevant when markets are incomplete. It shows that, if firms own the physical capital and undertake the investment decision to maximize their asset value, in the sense that they discount future cash flows with positive state price processes that are consistent with security prices, the equilibrium allocations are the same as in the standard setting with static firms. On the other hand, the firm valuation of future cash flows only coincides with the valuation of the unconstrained shareholders. Given this, value maximization may still lead to shareholder disagreement in the presence of effectively binding portfolio restrictions.

description: We report on the adsorption dynamics of phospholipid membranes on graphene-coated substrates using the quartz crystal microbalance with dissipation monitoring (QCM-D) technique. We compare the lipid vescle interaction and membranne formation on gold and silicon dioxide QCM crystal surfaces with their graphene oxide (GO) and reduced (r)GO coated counterparts, and report on the different lipid structures obtained. We establish graphene derivative coatings as support surfaces with tuneable hydrophobicity for the formation of controllable lipid structures. One structure of interest formed are lipid monolayer membrannes which were formed on rGO, which are otherwise challenging to produce. We also demonstrate and monitor biotin-avidin binding on such a membranne, which will then serve as a platform for a wide range of biosensing applications. The QCM-D technique could be extended to both fundamental studies and applications of other covalent and non-covalent interactions in 2-dimensional materials.

AMR sensing is well suited for NMR detection in microfluidic ``lab-on-a-chip'' applications.

description: Executive projects must guarantee that technical specifications are properly interpreted, so that construction work can be adequately implemented. In view of the upcoming automation of building sites arising from the cyber-physical system-based Industry 4.0 framework, the detailed design “grammar rules” are bound to change, too. The reported discussions focus on information integration between on-site and off-site production, as well as among humans, machines and sensors. This study surveys and updates the state of the art in the research of the building process automation. Based on that, it defines an information management model for integrated processes which encompasses the entire construction process (Integrated Design Process, Construction Management and Facility Management) and it is ready to be shared on the cloud.

Capital Gains Taxes and Portfolio Rebalancing

description: The major friction that investors face in rebalancing their portfolios is capital gains taxes, which are triggered by the sale of assets. In this article, we examine the impact of an investor’s capital gains tax liability and existing risk exposure upon the optimal portfolio and rebalancing decisions. We capture the trade-off over the investor’s lifetime between the tax costs and diversification benefits of trading. We find that the investor’s incentive to re-diversify the portfolio declines with the size of the capital gain and the investor’s age. Unlike conventional financial advice, the reset of the capital gains tax bases and the resulting elimination of the capital gains tax liability at death, suggests that the optimal equity proportion of the investor’s portfolio increases as he ages.
Interaction Matters: A Note on Non-asymptotic Local Convergence of Generative Adversarial Networks

description: Motivated by the pursuit of a systematic computational and algorithmic understanding of Generative Adversarial Networks (GANs), we present a simple yet unified non-asymptotic local convergence theory for smooth two-player games, which subsumes several discrete-time gradient-based saddle point dynamics. The analysis reveals the surprising nature of the off-diagonal interaction term as both a blessing and a curse. On the one hand, this interaction term explains the origin of the slow-down effect in the convergence of Simultaneous Gradient Ascent (SGA) to stable Nash equilibria. On the other hand, for the unstable equilibria, exponential convergence can be proved thanks to the interaction term, for four modified dynamics proposed to stabilize GAN training: Optimistic Mirror Descent (OMD), Consensus Optimization (CO), Implicit Updates (IU) and Predictive Method (PM). The analysis uncovers the intimate connections among these stabilizing techniques, and provides detailed characterization on the choice of learning rate. As a by-product, we present a new analysis for OMD proposed in Daskalakis, Ilyas, Syrgkanis, and Zeng [2017] with improved rates.

MHD Wave Propagation in the Neighbourhood of Two Null Points

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The nature of fast magnetoacoustic and Alfvén waves is investigated in a zero $β$ plasma in the neighbourhood of a pair of two-dimensional null points. This gives an indication of wave propagation in the low $β$ solar corona, for a more complicated magnetic configuration than that looked at by McLaughlin & Hood (2004). It is found that the fast wave is attracted to the null points and that the front of the wave slows down as it approaches the null point pair, with the wave splitting and part of the wave accumulating at one null and the rest at the other. Current density will then accumulate at these points and ohmic dissipation will then extract the energy in the wave at these points. This suggests locations where wave heating will occur in the corona. The Alfvén wave behaves in a different manner in that the wave accumulates along the separatrices. Hence, the current density will accumulate at this part of the topology and this is where wave heating will occur. However, the phenomenon of wave accumulation at a specific place is a feature of both wave types, and illustrates the importance of studying the topology of the corona when considering MHD wave propagation.

description: This study examines the relatively recent development of a “fixed-point proximity” approach to one type of minimization problem, considers its application to image denoising, and explores convergence and divergence of the iterative algorithm beyond a (previously supplied) theoretically guaranteed convergence bound on one of the parameters (𝜆). While reviewing the fixed-point proximity approach and its application to image denoising, we aim to communicate the concepts and details in a way that will facilitate understanding for undergraduates and for scholars from other subfields. In the latter portion of our study, the numerical experiment provides thought-provoking data on the effects that parameters 𝜇 and 𝜆 have on convergence or divergence once 𝜆 exceeds the range known to guarantee convergence.

description: This paper studies the effects of capacity utilization on accounting profit margins and stock returns. Since accounting profit margins represent the average profit per unit and not the economists' concept of unit contribution margin, the marginal/variable profit per unit, a firm with idle capacity can increase its profit margins by increasing sales (output). But, if the firm is operating at full capacity, an increase in output must be preceded by an increase in capacity (and fixed costs resulting in lower profit margins. Our empirical findings suggest that firms' profit margins increase in sales when there is idle capacity, but decreases in sales when the firm approaches full capacity. We show that firms experiencing high growth in sales operating in industries with high capacity utilization experience abnormally low stock returns in the following period.

It is also shown how generalized holomorphic structures arise naturally from the reduction procedure.

description: An authorial and hermetic concept of buildings no longer responds to shifting contemporary needs and lifestyles. A linearizing vision of the building process tends to limit technical design to the simple translation of design considerations into construction drawings. Any possibilities to define a broader framework of co-evolving relations between ideation, construction and the possibility to adapt what we build to unpredictable functional, social and economic changes are set aside. Rethinking the methods, contents and objectives of technical design presents an important challenge for extending the survival of a building. More important than the survival of an idea or form, this is a key element of the social, ecological and economic sustainability of making architecture.

description: The search for habitable planets like Earth around other stars fulfils an ancient imperative to understand our origins and place in the cosmos. The past decade has seen the discovery of hundreds of planets, but nearly all are gas giants like Jupiter and Saturn. Recent advances in instrumentation and new missions are extending searches to planets the size of the Earth, but closer to their host stars. There are several possible ways such planets could form, and future observations will soon test those theories. Many of these planets we discover may be quite unlike Earth in their surface temperature and composition, but their study will nonetheless inform us about the process of planet formation and the frequency of Earth-like planets around other stars.

Flux tubes and the type-I/type-II transition in a superconductor coupled to a superfluid

description: We analyze magnetic flux tubes at zero temperature in a superconductor that is coupled to a superfluid via both density and gradient (``entrainment'') interactions. The example we have in mind is high-density nuclear matter, which is a proton superconductor and a neutron superfluid, but our treatment is general and simple, modeling the interactions as a Ginzburg-Landau effective theory with four-fermion couplings, including only s-wave pairing. We numerically solve the field equations for flux tubes with an arbitrary number of flux quanta, and compare their energies. This allows us to map the type-I/type-II transition in the superconductor, which occurs at the conventional kappa = 1/sqrt(2) if the condensates are uncoupled. We find that a density coupling between the condensates raises the critical kappa and, for a sufficiently high neutron density, resolves the type-I/type-II transition line into an infinite number of bands corresponding to ``type-II(n)'' phases, in which n, the number of quanta in the favored flux tube, steps from 1 to infinity. For lower neutron density, the coupling creates spinodal regions around the type-I/type-II boundary, in which metastable flux configurations are possible. We find that a gradient coupling between the condensates lowers the critical kappa and creates spinodal regions. These exotic phenomena may not occur in nuclear matter, which is thought to be deep in the type-II region, but might be observed in condensed matter systems.

description: The energy landscape of multiverse cosmology is often modeled by a multi-dimensional random Gaussian potential. The physical predictions of such models crucially depend on the eigenvalue distribution of the Hessian matrix at potential minima. In particular, the stability of vacua and the dynamics of slow-roll inflation are sensitive to the magnitude of the smallest eigenvalues. The Hessian eigenvalue distribution has been studied earlier, using the saddle point approximation, in the leading order of $1/N$ expansion, where $N$ is the dimensionality of the landscape. This approximation, however, is insufficient for the small eigenvalue end of the spectrum, where sub-leading terms play a significant role. We extend the saddle point method to account for the sub-leading contributions. We also develop a new approach, where the eigenvalue distribution is found as an equilibrium distribution at the endpoint of a stochastic process (Dyson Brownian motion). The results of the two approaches are consistent in cases where both methods are applicable. We discuss the implications of our results for vacuum stability and slow-roll inflation in the landscape.

description: Microorganisms living in sub-zero environments can benefit from the presence of dissolved salts, as they significantly increase the temperature range of liquid water by lowering the freezing point. However, high concentrations of salts can reduce microbial growth and survival, and can evoke a physiological stress response. It remains poorly understood how the physicochemical parameters of brines (e.g. water activity, ionic strength, solubility and hydration shell strength between the ions and the surrounding water molecules) influence the survival of microorganisms. We used the cryo− and halotolerant bacterial strain Planococcus halocryophilus as a model organism to evaluate the degree of stress different salts assert. Cells were incubated in liquid media at −15°C containing single salts at eutectic concentrations (CaCl2, LiCl, LiI, MgBr2, MgCl2, NaBr, NaCl, NaClO4 and NaI). Four of these salts (LiCl, LiI, MgBr2 and NaClO4) were also investigated at concentrations with a low water activity (0.635) and, separately, with a high ionic strength (8 mol/L). Water activity of all solutions was measured at −15°C. This is the first time that water activity has been measured for such a large number of liquid salt solutions at constant sub-zero temperatures (−15°C). Colony-Forming Unit (CFU) counts show that the survival of P. halocryophilus has a negative correlation with the salt concentration, molecular weight of the anion and anion radius; and a positive correlation with the water activity and anions’ hydration shell strength. The survival of P. halocryophilus did not show a significant correlation with the ionic strength, the molecular weight of the cation, the hydrated and unhydrated cation and hydrated anion radius, and the cations’ hydration bond length. Thus, the water activity, salt concentration and anion parameters play the largest role in the survival of P. halocryophilus in concentrated brines. These findings improve our understanding of the limitations of microbial life in saline environments, which provides a basis for better evaluation of the habitability of extraterrestrial environments such as Martian cryobrines.

description: The Scholarship of Teaching and Learning (SoTL) is an opportunity for appreciating and using diversity in higher education: The research-based and systematically reflective engagement with one’s own teaching and the students’ learning offers room for dealing with the learning prerequisites and different resources of students as well as colleagues’ perspectives. Since its first naming in the 1990s, SoTL practices evolved and differentiated, making it difficult to define SoTL. There are not only diverse practices and focuses, but also different normative demands: While most SoTL work is oriented to students’ understanding within the disciplines, Kreber and Kranton suggest a broader view on SoTL including a critical perspective and transformative learning of both teachers and students. The international discussion is very lively, showing a development towards the acknowledgement of teaching and learning’s socio-political purposes. 

The SoTL discussion in the German speaking world is not parallel to the English speaking one: while SoTL took off in the United States in the 1990s , there was little visible activity in German-speaking countries for some time and basic discussions are still caught up with. This raises the question of whether international developments are having an impact in Germany: Do scholars in Germany use SoTL for their transformative learning to support students better or to involve them more? Do they orient their interest towards socio-political purposes or are they striving for discipline-specific knowledge on teaching and learning? Are there even specificities that might be inspiring for other contexts? 

To explore German scholars’ aims and place them against the background of the international development, the question guiding our study is: What are the aims that can be identified in current German SoTL publications? We take an empirical approach by conducting a literature review and subsequently discuss our findings against international claims and developments, including developments in other European countries.
title: Mindfulness: How it Affects Pregnancy, Labor and Delivery

description: Pregnancy is a very physical and mental process during which many women face a wide variety of complications. The influx of hormones that happens during pregnancy has the ability to make pregnant women more susceptible to depression, anxiety and other stress related illnesses. High levels of stress can negatively affect the mother and unborn child and potentially the mother-child relationship. Many women prefer not to take the pharmaceutical route when coping with stress, anxiety and depression while pregnant. As a result, mindfulness practices have been utilized as an alternative method to reduce the negative effects of these complications and lower their prevalence within the pregnant population. As a beneficial coping strategy for pain, anxiety, and stress, mindfulness promotes a better environment for the fetus during the perinatal period. Mindfulness practices have also been found to aid in the delivery process and improve parental self-efficacy due to its positive effects on maternal neuroplasticity and effective use as a stress reduction measure.

description: In the search for a novel MRI contrast agent which relies on T1 shortening due to quadrupolar interaction between Bi nuclei and protons, a fast scanning wideband system for zero-field nuclear quadrupole resonance (NQR) spectroscopy is required. Established NQR probeheads with motor-driven tune-match stages are usually bulky and slow, which can be prohibitive if it comes to Bi compounds with low SNR (excessive averaging) and long quadrupolar T1 times. Moreover many experiments yield better results at low temperatures such as 77K (liquid nitrogen, LN) thus requiring easy to use cryo-probeheads. In this paper we present electronically tuned wideband probeheads for bands in the frequency range 20 - 120 MHz which can be immersed in LN and which enable very fast explorative scans over the whole range. To this end we apply an interleaved subspectrum sampling strategy (ISS) which relies on the electronic tuning capability. The superiority of the new concept is demonstrated with an experimental scan of triphenylbismuth from 24-116 MHz both at room temperature and in LN. Especially for the first transition which exhibits extremely long T1 times (64ms) and low signal the new approach allows an acceleration factor by more than 100 when compared to classical methods.

description: Hot gluons are the dominant components of the QCD plasma to be formed in future high energy heavy ion experiments. In this paper we study the elementary processes in the plasma medium for gluon multiplication based on all orders of the tree-diagrams in perturbative QCD. When applying to the chemical equilibration in the expanding system, we found that the gluons reaches chemical equilibrium well within its plasma phase. The inclusion of all the next-to-leading order processes makes the equilibration considerably faster than the simple $gg\leftrightarrow ggg$ one considered previously.

description: We present measurements of the neutron-capture elements Rb and Pb for bright giants in the globular clusters M4 and M5. The clusters are of similar metallicity ([Fe/H] = -1.2) but M4 is decidedly s-process enriched relative to M5: [Ba/Fe] = +0.6 for M4 but 0.0 for M5. The Rb and Pb abundances were derived by comparing synthetic spectra with high-resolution, high signal-to-noise ratio spectra obtained with MIKE on the Magellan telescope. Abundances of Y, Zr, La, and Eu were also obtained. In M4, the mean abundances from 12 giants are [Rb/Fe] = 0.39 +/- 0.02 (sigma = 0.07), [Rb/Zr] = 0.17 +/- 0.03 (sigma = 0.08), and [Pb/Fe] = 0.30 +/- 0.02 (sigma = 0.07). In M5, the mean abundances from two giants are [Rb/Fe] = 0.00 +/- 0.05 (sigma = 0.06), [Rb/Zr] = 0.08 +/- 0.08 (sigma = 0.11), and [Pb/Fe] = -0.35 +/- 0.02 (sigma = 0.04). Within the measurement uncertainties, the abundance ratios [Rb/Fe], [Pb/Fe] and [Rb/X] for X = Y, Zr, La are constant from star-to-star in each cluster and none of these ratios are correlated with O or Na abundances. While M4 has a higher Rb abundance than M5, the ratios [Rb/X] are similar in both clusters indicating that the nature of the s-products are very similar for each cluster but the gas from which M4's stars formed had a higher concentration of these products.

description: We consider the problem of identifying the most influential nodes for a spreading process on a network when prior knowledge about structure and dynamics of the system is incomplete or erroneous. Specifically, we perform a numerical analysis where the set of top spreaders is determined on the basis of prior information that is artificially altered by a certain level of noise. We then measure the optimality of the chosen set by measuring its spreading impact in the true system. Whereas we find that the identification of top spreaders is optimal when prior knowledge is complete and free of mistakes, we also find that the quality of the top spreaders identified using noisy information doesn't necessarily decrease as the noise level increases. For instance, we show that it is generally possible to compensate for erroneous information about dynamical parameters by adding synthetic errors in the structure of the network. Further, we show that, in some dynamical regimes, even completely losing prior knowledge on network structure may be better than relying on certain but incomplete information.
