description: We study a class of Monte Carlo algorithms for the nonlinear $σ$-model, based on a Wolff-type embedding of Ising spins into the target manifold $M$. We argue heuristically that, at least for an asymptotically free model, such an algorithm can have dynamic critical exponent $z \ll 2$ only if the embedding is based on an (involutive) isometry of $M$ whose fixed-point manifold has codimension 1. Such an isometry exists only if the manifold is a discrete quotient of a product of spheres. Numerical simulations of the idealized codimension-2 algorithm for the two-dimensional $O(4)$-symmetric $σ$-model yield $z_{int,{\cal M}^2} = 1.5 \pm 0.5$ (subjective 68\% confidence interval), in agreement with our heuristic argument.

description: With the rise of machine learning, there is a great deal of interest in treating programs as data to be fed to learning algorithms. However, programs do not start off in a form that is immediately amenable to most off-the-shelf learning techniques. Instead, it is necessary to transform the program to a suitable representation before a learning technique can be applied. In this paper, we use abstractions of traces obtained from symbolic execution of a program as a representation for learning word embeddings. We trained a variety of word embeddings under hundreds of parameterizations, and evaluated each learned embedding on a suite of different tasks. In our evaluation, we obtain 93% top-1 accuracy on a benchmark consisting of over 19,000 API-usage analogies extracted from the Linux kernel. In addition, we show that embeddings learned from (mainly) semantic abstractions provide nearly triple the accuracy of those learned from (mainly) syntactic abstractions.

description: Computing the entanglement entropy in confining gauge theories is often accompanied by puzzles and ambiguities. In this work we show that compactifying the theory on a small circle $\mathbb S^1_L$ evades these difficulties. In particular, we study Yang-Mills theory on $\mathbb R^3\times \mathbb S^1_L$ with double-trace deformations or adjoint fermions and hold it at temperatures near the deconfinement transition. This theory is dual to a multi-component (electric-magnetic) Coulomb gas that can be mapped either to an XY-spin model with $\mathbb Z_p$-preserving perturbations or dual Sine-Gordon model. The entanglement entropy of the dual Sine-Gordon model exhibits an extremum at the critical temperature/crossover. We also compute Renyi mutual information (RMI) of the XY-spin model by means of the replica trick and Monte Carlo simulations. These are expensive calculations, since one in general needs to suppress lower winding vortices that do not correspond to physical excitations of the system. We use a T-duality that maps the original XY model to its mirror image, making the extraction of RMI a much efficient process. Our simulations indicate that RMI follows the area law scaling, with subleading corrections, and this quantity can be used as a genuine probe to detect deconfinement transitions. We also discuss the effect of fundamental matter on RMI and the implications of our findings in gauge theories and beyond.

The Welfare Cost of Business Cycles Revisited: Finite Lives and Cyclical Variation in Idiosyncratic Risk

description: This paper investigates the welfare costs of business cycles in a heterogeneous agent, overlapping generations economy which is distinguished by idiosyncratic labor market risk. Aggregate variation arises both in terms of aggregate productivity shocks and countercyclical variation in the volatility of idiosyncratic shocks. Based on both aggregate data and microeconomic data from the Panel Study on Income Dynamics, we find the welfare benefits of eliminating aggregate variation to be large – an order of magnitude larger than those originally documented by Lucas (1987). The key difference is countercyclical variation in idiosycratic risk, which both amplifies the welfare cost of aggregate productivity shocks and imposes a cost of its own. The magnitude of these effects increases non-linearly in risk aversion. Our results, therefore, are consistent with the increasingly popular notion that distributional effects are an important aspect of understanding the welfare cost of business cycles.

description: We investigate an extension of the $Λ$CDM model where the dark matter (DM) is coupled to photons, inducing a nonconservation of the numbers of particles for both species, where the DM particles are allowed to dilute throughout the cosmic history with a small deviation from the standard evolution decaying into photons, while the associated scattering processes are assumed to be negligible. In addition, we consider the presence of massive neutrinos with the effective number of species $N_{\rm eff}$ as a free parameter. The effects of the DM-photon coupling on the cosmic microwave background (CMB) and matter power spectra are analyzed. We derive the observational constraints on the model parameters by using the data from CMB, baryonic acoustic oscillation (BAO) measurements, the recently measured new local value of the Hubble constant from the Hubble Space Telescope, and large scale structure (LSS) information from the abundance of galaxy clusters. The DM-photon coupling parameter $Γ_{γ}$ is constrained to $Γ_{γ} \leq 1.3 \times10^{-5}$ (at 95\% C.L.) from the joint analysis carried out by using all the mentioned data sets. The neutrino mass scale $\sum m_ν$ upper bounds at 95\% C.L. are obtained as $\sum m_ν \sim 0.9$ eV and $\sum m_ν \sim 0.4$ eV with and without the LSS data, respectively. We observe that the DM-photon coupling cause significant changes in the best fit value of $N_{\rm eff}$ but yields statistical ranges of $N_{\rm eff}$ compatible with the standard predictions, and we do not find any evidence of dark radiation. Due to nonconservation of photons in our model, we also evaluate and analyze the effects on the BAO acoustic scale at the drag epoch. The DM-photon coupling model yields high values of Hubble constant consistent with the local measurement, and thus alleviates the tension on this parameter.

Year: 1993
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Grand unified theories often predict unification of Yukawa couplings (e.g., $h_{b} = h_τ$), and thus certain relations among fermion masses. The latter can distinguish these from models that predict only coupling constant unification. The implications of Yukawa couplings of the heavy-family in the supersymmetric extension of the standard model (when embedded in a GUT) are discussed. In particular, uncertainties associated with $m_{t}$ and $m_{b}$, threshold corrections at the low-scale, and threshold and nonrenormalizable-operator corrections associated with a grand-unified sector at the high-scale are parametrized and estimated. The implication of these and of the correlation between $m_{t}$ and the prediction for $α_{s}$ are discussed. Constraints on the $\tanβ$ range in such models and an upper bound on the $t$-quark pole mass are given and are shown to be affected by the $α_{s}-m_{t}$ correlation. Constraints on the low-scale thresholds are found to be weakened by uncertainties associated with the high-scale.

description: Electromagnetic (EM) counterparts to supermassive black hole binary mergers observed by LISA can be localized to within the field of view of astronomical instruments ~10 deg^2 hours to weeks prior to coalescence. The temporal coincidence of any prompt EM counterpart with a gravitationally-timed merger may offer the best chance of identifying a unique host galaxy. We discuss the challenges posed by searches for prompt EM counterparts and propose novel observational strategies to address them. In particular, we discuss the size and shape evolution of the LISA localization error ellipses on the sky, and quantify the requirements for dedicated EM surveys of the area prior to coalescence. A triggered EM counterpart search campaign will require monitoring a several-square degree area. It could aim for variability at the 24-27 mag level in optical bands, for example, which corresponds to 1-10% of the Eddington luminosity of the prime LISA sources of 10^6-10^7 Msun BHs at z=1-2, on time-scales of minutes to hours, the orbital time-scale of the binary in the last 2-4 weeks. A cross-correlation of the period of any variable EM signal with the quasi-periodic gravitational waveform over 10-1000 cycles may aid the detection. Alternatively, EM searches can detect a transient signal accompanying the coalescence. We highlight the measurement of differences in the arrival times of photons and gravitons from the same cosmological source as a valuable independent test of the massive character of gravity, and of possible violations of Lorentz invariance in the gravity sector.

description: Neutron scattering experiments have been performed on the ternary rare-earth diborocarbide Ce$^{11}$B$_2$C$_2$. The powder diffraction experiment confirms formation of a long-range magnetic order at $T_{\rm N} = 7.3$ K, where a sinusoidally modulated structure is realized with the modulation vector ${\bm q} = [0.167(3), 0.167(3), 0.114(3)]$. Inelastic excitation spectra in the paramagnetic phase comprise significantly broad quasielastic and inelastic peaks centered at $\hbar ω\approx 0, 8$ and 65 meV. Crystalline-electric-field (CEF) analysis satisfactorily reproduces the observed spectra, confirming their CEF origin. The broadness of the quasielastic peak indicates strong spin fluctuations due to coupling between localized $4f$ spins and conduction electrons in the paramagnetic phase. A prominent feature is suppression of the quasielastic fluctuations, and concomitant growth of a sharp inelastic peak in a low energy region below $T_{\rm N}$. This suggests dissociation of the conduction and localized $4f$ electrons on ordering, and contrasts the presently observed incommensurate phase with spin-density-wave order frequently seen in heavy fermion compounds, such as Ce(Ru$_{1-x}$La$_x$)$_2$Si$_2$.

A Critique of the Fuzzball Program

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We explore the viability of fuzzballs as candidate microstate geometries for the black hole, and their possible role in resolutions of the information paradox. We argue that if fuzzballs provide a description of black-hole microstates, then the typical fuzzball geometry can only differ significantly from the conventional black-hole geometry at a Planck-scale-distance from the horizon. However, precisely in this region, quantum fluctuations in the fuzzball geometry become large and the fuzzball geometry becomes unreliable. We verify these expectations through a detailed calculation of quantum expectation values and quantum fluctuations in the two-charge fuzzball geometries. We then examine some of the solutions discovered in arXiv:1607.03908. We show, based on a calculation of a probe two-point function in this background, that these solutions, and others in their class, violate robust expectations about the gap in energies between successive energy eigenstates, and differ too much from the conventional black hole to represent viable microstates. We conclude that while fuzzballs are interesting star-like solutions in string theory, they do not appear to be relevant for resolving the information paradox, and cannot be used to make valid inferences about black-hole interiors.

description: The dynamics and thermal equilibrium of spin waves (magnons) in a quantum ferromagnet as well as the macroscopic magnetisation are investigated. Thermal noise due to an interaction with lattice phonons and the effects of spatial correlations in the noise are considered. We first present a Markovian master equation approach with analytical solutions for any homogeneous spatial correlation function of the noise. We find that spatially correlated noise increases the decay rate of magnons with low wave vectors to their thermal equilibrium, which also leads to a faster decay of the ferromagnet's magnetisation to its steady-state value. For long correlation lengths and higher temperature we find that additionally there is a component of the magnetisation which decays very slowly, due to a reduced decay rate of fast magnons. This effect could be useful for fast and noise-protected quantum or classical information transfer and magnonics. We further compare ferromagnetic and antiferromagnetic behaviour in noisy environments and find qualitatively similar behaviour in Ohmic but fundamentally different behaviour in super-Ohmic environments.

description: We construct an improved version of nonrelativistic QCD for use in lattice simulations of heavy quark physics, with the goal of reducing systematic errors from all sources to below 10\%. We develop power counting rules to assess the importance of the various operators in the action and compute all leading order corrections required by relativity and finite lattice spacing. We discuss radiative corrections to tree level coupling constants, presenting a procedure that effectively resums the largest such corrections to all orders in perturbation theory. Finally, we comment on the size of nonperturbative contributions to the coupling constants.

The Value of Better Weather Information to the Raisin Industry

Subjects: subject: 150399 Business and Management not elsewhere classified
subject: FOS: Economics and business

description: This report utilizes decision theory to investigate the possible benefits of better weather information to California raisin growers. A supply curve is fitted to the raisin industry and used to evaluate the importance of various factors: weather is of overwhelming importance. Subsequent analysis focuses on the most vulnerable aspect of raisin production: its dependence on early forecasts of rain in September and October when the grapes are being dried and in danger of being damaged by rain. Section 1, in the tradition of micro-economic, partial equilibrium analysis, is concerned with the value of weather information to a single grower. Only the grower focused upon is assumed to receive the better information. This assumption implies there is high value for forecasting rain three weeks in advance. A figure of 90.95 per acre is the value of perfect three week forecasts. Were this value to be realized for each bearing acre in 1960, the total value of better weather information to the raisin industry would be 20,300,000. But merely summing across firms to get industry totals may lead to a fallacy of composition: the analysis must be extended to a wider partial equilibrium framework. Section 2 examines the value of better weather information to the raisin industry as a whole. Since costs are not greatly affected by improved weather information, profit differences are closely approximated by changes in revenue. The elasticity of demand for raisins is calculated from a demand curve fitted to industry data. The inelasticity of demand causes profit to fall under the impact of better information, at least in the short run. The scope of the analysis is then extended to other industries. Using this wider viewpoint, the Conclusion examines the possibility of a simple tax that would reallocate land and labor. The presence of released resources seems to imply a clear gain for better information. However, the basis of such a gain is positive value for these resources in other uses. But the short run inelasticity of other possible products makes it clear that, at least in the short run, better weather information results in net loss. However, some relief is offered through the possibility of regulation. An Appendix examines the question of the value of inaccurate forecasts.

description: The gravitational lens system CLASS B2108+213 has two lensed images separated by 4.56 arcsec. Such a wide image separation suggests that the lens is either a massive galaxy, or is composed of a group of galaxies. To investigate the structure of the lensing potential we have carried out new high resolution imaging of the two lensed images at 1.7 GHz with the VLBA and at 5 GHz with global VLBI. Compact and extended emission is detected from the two lensed images, which provides additional constraints to the lensing mass model. We find that the data are consistent with either a single lensing galaxy, or a two galaxy lens model that takes account of a nearby companion to the main lensing galaxy within the Einstein radius of the system. However, for an ensemble of global power-law mass models, those with density profiles steeper than isothermal are a better fit. The best-fitting profile for a single spherical mass model has a slope of $γ=$~2.45$_{-0.18}^{+0.19}$. The system also has a third radio component which is coincident with the main lensing galaxy. This component is detected at milli-arcsecond scales for the first time by the 1.7 GHz VLBA and 5 GHz global VLBI imaging. However, the third radio component is found not to be consistent with a core lensed image because the radio spectrum differs from the two lensed images, and its flux-density is too high when compared to what is expected from simple mass models with a variable power-law density profile and/or a reasonable core radius. Furthermore, 1.4 GHz imaging of the system with the MERLIN finds extended lobe emission on either side of the main lensing galaxy. Therefore, the radio emission from the third radio component is almost certainly from an AGN within the main lensing galaxy, which is classified as an FR I type radio source.

description: At radio wavelengths, solar-type stars emit thermal free-free and gyroresonance, gyrosynchrotron, and impulsive coherent emission. Thermal free-free emission originates at layers where the optical depth is close to unit, while high brightness temperature, variable emission, can be due to flares via gyrosynchrotron emission. We observed the alpha Cen system with the Australian Telescope Compact Array at 2 GHz for three days and 17 GHz for one day. Both stars have been detected at 17 GHz, while only an upper limit has been obtained at low frequency despite the longer integration time. The brightness temperatures are consistent with the temperature of the upper chromosphere of the Sun. Inverting the formulae of the free-free emission, the average electron density of the plasma has been inferred. The same procedure was applied to the data in the millimetre recently acquired with ALMA. A comparison with the atmospheric solar models reveals a higher level of activity in alpha Cen B rather than in alpha Cen A, even if still at quiescent level. The non detection at 2 GHz allows us to put a lower limit in the filling factor of active regions. The claimed detection of an Earth size planet in close orbit to alpha Cen B, although doubtful, opens the opportunity to check the existence of Star-Planet Magnetic Interaction (SPMI). We constructed dynamic spectra in the 1.3 - 2.9 GHz of the 2 stars to search for time-variable coherent emission but obtained a null result.

description: Almost 30% of aquatic grasses worldwide are either lost or degraded (Barbier et al, 2011). The Chesapeake Bay is no exception, with levels of submerged aquatic vegetation (SAV) remaining below half of the historic levels. This decline is largely attributed to excessive nutrient and sediment loads degrading Bay water quality. SAV provide many important functions to natural ecosystems, many of which are directly beneficial to local residents. To understand the implicit value residents place on SAV and the localized ecosystem services it provides, we undertake a hedonic property value study using residential transaction data from 1996 to 2008 in eleven Maryland counties adjacent to the Chesapeake Bay. These data are matched to high resolution maps of Baywide SAV coverage. We pose a quasi-experimental comparison and examine how the price of homes near and on the waterfront vary with the presence of SAV. On average, waterfront and near-waterfront homes within 200 meters of the shore sell at a 5% to 6% premium when SAV are present. Applying these estimates to the 185,000 acre SAV attainment goal yields total property value gains on the order of $300 to 400 million.

The final result is changed drastically. Doing an expansion in the Higgs mass I show that the matrix element is identically 0 in the order (MZ/MH)^2, which is due to gauge invariance. Left with an amplitude of the order (MZ/MH)^4 the final result is that the scalar contribution to this decay rate is several orders of magnitude smaller than those of the W boson and fermions.

description: This Deliverable 2.1a is an interim airborne LiDAR report developed within a collaboration between WP2.1 (E. Lozić) and WP4.1 (B. Štular, M. Belak, A. Pleterski). Due to the specific archaeology, geology and geomorphology of the Bled micro-region the archaeological interpretation of airborne LiDAR derived data has been focused on detecting new Late Antiquity Period settlements. As in any airborne LiDAR analysis entire archaeological landscape record must be taken into account. Over 1000 features has been recorded, 265 of those are potential archaeological features. As the most important result of this analysis a discovery of previously unknown Prehistoric and Late Antiquity Period hillfort settlement on Ribenska gora is to be mentioned.

Resolution of the problem is central to an understanding of the difference between a monetary and a nonmonetary or barter economy, and there have been numerous attempts at resolution. The use of money or the existence of a positive demand has been made to depend on such diverse factors as the anticipation of price or interest rate changes, uncertainty, the embarrassment of default, legal restrictions, or some undefined set of "services"—such as "liquidity"— that money provides. Probably the dominant, current explanation posits the existence of a number of ostensibly separate "motives for holding money." This explanation coexists with vestiges of an earlier preferred explanation that made the use and/or holding of money depend on the "functions" performed by money, such as medium of exchange, store of value and unit of account.

description: It is well known that reconstruction problems, as the interdisciplinary subject, have been studied in numerous contexts including statistical physics, information theory and computational biology, to name a few. We consider a $2q$-state symmetric model, with two categories of $q$ states in each category, and 3 transition probabilities: the probability to remain in the same state, the probability to change states but remain in the same category, and the probability to change categories. We construct a nonlinear second order dynamical system based on this model and show that the Kesten-Stigum reconstruction bound is not tight when $q \geq 4$.

description: We study the formation and evolution of an interconnected string network in large-scale field-theory numerical simulations, both in flat spacetime and in expanding universe. The network consists of gauge U(1) strings of two different kinds and their bound states, arising due to an attractive interaction potential. We find that the network shows no tendency to ``freeze'' and appears to approach a scaling regime, with all characteristic lengths growing linearly with time. Bound strings constitute only a small fraction of the total string length in the network.

description: Magnetic resonance spectroscopic imaging (SI) is a unique imaging technique that provides biochemical information from in vivo tissues. The 1H spectra acquired from several spatial regions are quantified to yield metabolite concentrations reflective of tissue metabolism. However, since these metabolites are found in tissues at very low concentrations, SI is often acquired with limited spatial resolution. In this work we test the hypothesis that deep learning is able to upscale low resolution SI, together with the T1-weighted (T1w) image, to reconstruct high resolution SI. We report a novel densely connected Unet (D-Unet) architecture capable of producing super-resolution spectroscopic images. The inputs for the D-UNet are the T1w image and the low resolution SI image while the output is the high resolution SI. The results of the D-UNet are compared both qualitatively and quantitatively to simulated and in vivo high resolution SI. It is found that this deep learning approach can produce high quality spectroscopic images and reconstruct entire 1H spectra from low resolution acquisitions, which can greatly advance the current SI workflow.

description:
In the United States, the use of pre-exposure prophylaxis (PrEP) has led to a substantial decrease in HIV prevalence and incidence. However, some populations, including young men who have sex with men (YMSM) of color, continue to be disproportionately impacted, highlighting the need for tailored interventions addressing barriers to adequate PrEP access. In collaboration with partner clinics, we recruited 19 PrEP clients and 19 PrEP providers (n = 35) to participate in hour-long in-depth interviews. Although client interviews explored personal experiences with stigma, barriers, and motivators to PrEP and information preferences, provider interviews explored providers' perceived stigma in their clinic, perceived barriers and motivators to meeting clients' PrEP needs, and rapport building with clients. Most participants were affiliated with one of the southern partner clinics. Clients and providers noted similar determinants to PrEP access, uptake, and adherence. Both recognized the impact of personal barriers such as routine adjustments and perception of need, as well as institutional barriers such as transportation and financial difficulties. Clients emphasized the role of the client-provider relationship as part of contributing to willingness to disclose information such as HIV status and sexual practices. Providers noted the importance of sexual health and LGBTQ+ topics in their training. Despite limited geographical scope and the sensitive nature of HIV-related topics, this study has several implications. PrEP clinics may benefit from hiring providers who share identities and experiences with YMSM clients of color and operating with a flexible schedule. Medical provider training should include comprehensive sexual health and LGBTQ+ competencies to reduce bias in care.

description: Let $Y$ and $Z$ be two fixed topological spaces and $C(Y,Z)$ the set of all continuous maps from $Y$ into $Z$. We construct and study topologies on $C(Y,Z)$ that we call ${\cal F}_n(τ_n)$-family-open topologies. Furthermore, we find necessary and sufficient conditions such that these topologies to be splitting and jointly continuous. Finally, we present questions concerning a further study on this area.

Ising Model Coupled to Three-Dimensional Quantum Gravity

description: We have performed Monte Carlo simulations of the Ising model coupled to three-dimensional quantum gravity based on a summation over dynamical triangulations. These were done both in the microcanonical ensemble, with the number of points in the triangulation and the number of Ising spins fixed, and in the grand canoncal ensemble. We have investigated the two possible cases of the spins living on the vertices of the triangulation (``diect'' case) and the spins living in the middle of the tetrahedra (``dual'' case). We observed phase transitions which are probably second order, and found that the dual implementation more effectively couples the spins to the quantum gravity.

description: In our analysis of current Federal Reserve policy, the SOMC makes use of some explicit numerical rules, including the justly famous Taylor rule, for the conduct of monetary policy. The purpose of this paper is to discuss the way in which we do this, pointing out several issues concerning crucial details. In addition, the logic of the Taylor rule, as well as a base money rule promoted in my own work (e.g., McCallum, 1988), will be outlined and a different way of using the rules will be briefly mentioned. Finally, I will provide a bit of commentary on current conditions.

description: We analyze in detail the electronic properties of high pressure hydrogen around the liquid-liquid phase transition based on Coupled Electron-Ion Monte Carlo calculations. Computing the off-diagonal single particle density matrix and the momentum distribution we discuss localization properties of the electrons. The abrupt changes of these distributions indicate a metal to insulator transition occurring together with the structural transition from the atomic to molecular fluid. We further discuss the electron-proton and electron-electron pair correlation functions, which also change abruptly at the transition.

description: In meinem Beitrag diskutiere ich, inwiefern die Anerkennung von Differenz als Basis für feministische Solidarität dienen kann. Ich verbinde die Debatten innerhalb postkolonial-feministischer Theorie über die Un/Möglichkeiten von feministischer Solidarität mit der Perspektive der Politischen Ontologie, um Kosmopolitik als die Verhandlungen zwischen miteinander in ungleicher Beziehung verbundener heterogener Welten zu greifen. Dafür untersuche ich zwei Bewegungstreffen in Peru, die Fünften Dialogen zwischen Bewegungen und Wissen sowie das 13. Feministische Lateinamerikanische und Karibische Treffen. Um zu analysieren, wie Differenz auf den beiden Treffen konstruiert wird und welche Effekte dies auf die Möglichkeit hat, Solidarität zu praktizieren, schlage ich zwei Konstellationen von Solidarität und Kosmopolitik vor: Kosmopolitische Solidarität bezeichnet eine Haltung gegenüber als different betrachteten Gruppen und Individuen, die Differenz als Stärke emanzipatorischer Kämpfe sieht. Statt exklusive Grenzen zu betonen, wird die Intersektionalität verschiedener Kämpfe anerkannt, das geteilte politische Bewusstsein wird als erst im gemeinsamen Kampf geschaffen gesehen, und die Praxis der Imagination wird eingesetzt, um potenzielle Inkommensurabilitäten zu überbrücken. Kosmopolitik der Solidarität meint hingegen die Praxen der Solidarität, die heterogene und potenziell nicht ineinander aufgehende Kämpfe verschränken und auf wechselseitiger Kritik aufbauen. Erst die gemeinsame Betrachtung beider Konstellationen, so mein Argument, kann die machtvollen Aushandlungsprozesse fassen, die feministische Solidarität als dekolonisierende Praxis ermöglichen.
