description: All clocks, classical or quantum, are open non equilibrium irreversible systems subject to the constraints of thermodynamics. Using examples I show that these constraints necessarily limit the performance of clocks and that good clocks require large energy dissipation. For periodic clocks, operating on a limit cycle, this is a consequence of phase diffusion. It is also true for non periodic clocks (for example, radio carbon dating) but due to telegraph noise not to phase diffusion. In this case a key role is played by accurate measurements that decrease entropy, thereby raising the free energy of the clock, and requires access to a low entropy reservoir. In the quantum case, for which thermal noise is replaced by quantum noise (spontaneous emission or tunnelling), measurement plays an essential role for both periodic and non periodic clocks. The paper concludes with a discussion of the Tolman relations and Rovelli's thermal time hypothesis in terms of clock thermodynamics.

description: This study undertakes a systematic experimental investigation of hysteresis (path dependency) in an agent-based computational labor market framework. It is shown that capacity asymmetries between work suppliers and employers can result in two distinct hysteresis effects, network and behavioral, when work suppliers and employers interact strategically and evolve their worksite behaviors over time. These hysteresis effects result in persistent heterogeneity in earnings and employment histories across agents who have no observable structural differences. At a more global level, these hysteresis effects are shown to result in a one-to-many mapping between treatment factors and experimental outcomes. These hysteresis effects may help to explain why excess earnings heterogeneity is commonly observed in real-world labor markets.

On the origin of the drifting subpulses in radio pulsars

description: A model for the main observational characteristics of the radio emission of pulsars with well organized drifting subpulses is presented. We propose that drifting subpulses result from the modulation of the radio emission mechanism due to long-wavelength drift waves in the magnetosphere. The drift waves are generated at shorter wavelengths, and their nonlinear evolution favours accumulation in a specific azimuthal eigenmode with an integral number, $m$, of nodes encircling the magnetic pole. The electric field of the drift waves is along the magnetic field lines, and this modulates the distribution for particles and hence the radio emission mechanism. The ratio of the frequency of the eigenmode to the rotation frequency of the star is insensitive to the magnetic field strength and the period of rotation, and is of order unity. The period, $P_3$, of the drifting subpulses is attributed to the mismatch between this frequency and the nearest harmonic of the rotation frequency of the star.

description: Experiments with real and computational agents are used to examine the impact of changing the level of a non-employment payoff on the evolution of cooperation between workers and employers participating in a sequential employment game with incomplete contracts. Workers either direct work offers to preferred employers or choose unemployment and receive the non-employment payoff. Subject to capacity limitations, employers either accept work offers from preferred workers or remain vacant and receive the non-employment payoff. Matched workers and employers participate in an employment relationship modeled as a prisoner's dilemma game. In both types of experiments, increases in the non-employment payoff result in higher unemployment and vacancy rates while at the same time encouraging higher rates of cooperation among the workers and employers who do form matches. However, the behaviors exhibited by the computational agents are coordinated to a higher degree than the behaviors of the human subjects. This difference raises challenging questions for both human-subject and computational experimentalists.

description: Secure software leasing (SSL) is a quantum cryptographic primitive that enables users to execute software only during the software is leased. It prevents users from executing leased software after they return the leased software to its owner. SSL can make software distribution more flexible and controllable. Although SSL is an attractive cryptographic primitive, the existing SSL scheme is based on public key quantum money, which is not instantiated with standard cryptographic assumptions so far. Moreover, the existing SSL scheme only supports a subclass of evasive functions. In this work, we present SSL schemes based on the learning with errors assumption (LWE). Specifically, our contributions consist of the following. - We construct an SSL scheme for pseudorandom functions from the LWE assumption against quantum adversaries. - We construct an SSL scheme for a subclass of evasive functions from the LWE assumption against sub-exponential quantum adversaries. - We construct SSL schemes for the functionalities above with classical communication from the LWE assumption against (sub-exponential) quantum adversaries. SSL with classical communication means that entities exchange only classical information though they run quantum computation locally. Our crucial tool is two-tier quantum lightning, which is introduced in this work and a relaxed version of quantum lighting. In two-tier quantum lightning schemes, we have a public verification algorithm called semi-verification and a private verification algorithm called full-verification. An adversary cannot generate possibly entangled two quantum states whose serial numbers are the same such that one passes the semi-verification, and the other also passes the full-verification. We show that we can construct a two-tier quantum lightning scheme from the LWE assumption.

description: The benefits of portfolio diversification is a central tenet implicit to modern financial theory and practice. Linked to diversification is the notion of breadth. Breadth is correctly thought of as the number of in- dependent bets available to an investor. Conventionally applications us- ing breadth frequently assume only the number of separate bets. There may be a large discrepancy between these two interpretations. We uti- lize a simple singular-value decomposition (SVD) and the Keiser-Gutman stopping criterion to select the integer-valued effective dimensionality of the correlation matrix of returns. In an emerging market such as South African we document an estimated breadth that is considerably lower than anticipated. This lack of diversification may be because of market concentration, exposure to the global commodity cycle and local currency volatility. We discuss some practical extensions to a more statistically correct interpretation of market breadth, and its theoretical implications for both global and domestic investors.

description: In spite of intensive studies on the chalcogenides as conventional thermoelectrics, it remains a challenge to find a proper material with high electrical but low thermal conductivities. In this work, we introduced a new class of thermoelectrics, Ge-based inorganic halide perovskites \ce{CsGeX3} (X = I, Br, Cl), which were already known as a promising candidate for photovoltaic applications. By performing the lattice-dynamics calculations and solving the Boltzmann transport equation, we revealed that these perovskites have ultralow thermal conductivities below 0.18 W m$^{-1}$ K$^{-1}$ while very high carrier mobilities above 860 cm$^2$ V$^{-1}$ s$^{-1}$, being much superior to the conventional thermoelectrics of chalcogenides. These results highlight the way of searching high-performance and low-cost thermoelectrics based on inorganic halide perovskites.

description: Using density functional theory with the generalized gradient approximation and ultra-soft pseudo-potentials, we have calculated structural relaxations of the Cu(532) surface which contains steps and kinks. We find the relaxation pattern to oscillate dramatically for atoms in the first 10 layers before decaying rapidly in the bulk. The most striking feature is an outward expansion of the relative interlayer separation $\mathbf{d}_{12}$ of 25%. We also find serious discrepancies with relaxation pattern and relaxation amplitudes calculated using embedded atom method potentials that may reflect the limitation of these potentials to accurately describe systems with complex geometries. Full potential calculations reveal a dispersionless surface state along a high symmetry direction in the surface Brillouin zone. Valence charge density along several planes show access of charge around kink atom and the nature of bonding with other (532) atoms.

description: Topology and strong electron correlations are crucial ingredients in emerging quantum materials, yet their intersection in experimental systems has been relatively limited to date. Strongly correlated Weyl semimetals, particularly when magnetism is incorporated, offer a unique and fertile platform to explore emergent phenomena in novel topological matter and topological spintronics. The antiferromagnetic Weyl semimetal Mn3Sn exhibits many exotic physical properties such as a large spontaneous Hall effect and has recently attracted intense interest. In this work, we report synthesis of epitaxial Mn3+xSn1-x films with greatly extended compositional range in comparison with that of bulk samples. As Sn atoms are replaced by magnetic Mn atoms, the Kondo effect, which is a celebrated example of strong correlations, emerges, develops coherence, and induces a hybridization energy gap. The magnetic doping and gap opening lead to rich extraordinary properties as exemplified by the prominent DC Hall effects and resonance-enhanced terahertz Faraday rotation.

description: Bhakti Movement in India and Negro Spirituals in America are both created out of social misconduct and spiritual inclination to solve this misconduct. Bhakti Movement started to address the issues of Caste discrimination in Indian subcontinent and Nero Spirituals were created by the Africans who were captured ns brought to the US as slaves. Bhakti poets were denied social acceptance because of their low caste and Africans were deprived of their languages, families and cultures. But music and songs bound these two down-trodden communities. Over the years these African slaves and their dependents adopted Christianity and reshaped it into a deeply personal way to deal with their personal oppression and trauma. Just like that, the Bhakti Poets created their own faith by having their personal relation, sometimes to their personal God. This article compares some of the socio-religious similarities between the Bhakti Movement and the Negro Spirituals.

description: Creativity is defined as the ability to generate new ideas or concepts, of new associations between known ideas and concepts, which usually produce original solutions. On the other hand, innovation is conceived as a process that introduces new features and refers to modifying existing elements in order to improve them, although it is also possible in the implementation of totally new elements. Today, university education focuses on training young people who have followed a previous process of basic education, based on standardized basic parameters worldwide and leading them to direct their professional life to a specific field, be it engineering, health sciences, economics or some other different area; However, third-level education, like secondary or primary, has continued with a continuous and monotonous approach, where students are taught to follow a group of steps to reach an objective or solution and students are not educated. themselves in a way that they can create new techniques or innovate on existing ones. The present work aims to identify which is the ideal profile of university students in terms of innovation and creativity, recognize the presence of these characteristics in students and their relationship with adaptation to life and the university context.

description: Prior information about the input state can be utilized to enhance the efficiency of quantum teleportation which we quantify using the first two moments of fidelity. The input knowledge is introduced by relaxing the uniformity assumption in the distribution of the input state and considering non-uniform distributions, namely the polar cap and von Mises-Fisher densities. For these distributions,we show that the average fidelity increases while the deviation decreases with the increase of information content about the input ensemble thereby establishing its role as a resource. Our comparative study between these two distributions reveals that for the same amount of information content about inputs, although the average fidelity yield is the same for both, the polar cap distribution is "better" as it offers a smaller deviation. Moreover, we contrast the resource of prior information with other resources involved in the protocol like shared entanglement and classical communication. Specifically, we observe that unlike uniform distribution, the amount of classical communication required to fulfill the task decreases with the increase of information available for inputs. We also investigate the role of prior information in higher (three) dimensional teleportation and report the signatures of dimensional advantage in prior information-based teleportation.

Dwellers of memory : an ethnography of place, memory and violence in Medellín, Colombia
Creators: name: Riaño Alcalá, Pilar
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation documents the memories of Medellin's city dwellers and explores how people in violent urban contexts make sense of violence and deal with its presence in their lives. This study is defined as an anthropology of remembering; it is an ethnographic observation of the practices of remembering and forgetting and how these practices shape and are shaped by the lived experience of violence. The dissertation is built on extensive fieldwork in the Colombian city of Medellin with a cross section of women, youth and community leaders. The thesis argues that when the uncertainty and paradox created by widespread forms of violence threaten to destroy the social and material worlds of Colombian city dwellers, memory becomes a strategic tool for human and cultural survival. The creation of an oral history of death and the dead, the presence of a local social knowledge that assists city dwellers in their safe circulation in and through the city, and the maintenance of practices of place making are examples of how city dwellers deal with the devastating effects of violence in their lives. The thesis develops a place-based exploration of memory and violence and approaches place as a physical, sensory, social and imaginative experience that maintains a sense of continuity between the past and the every day life of Medellin's city dwellers. The two connecting concepts that ground the analysis of the relationship between people, memory and violence are those of "sense of place" and "communities of memory." The dimensions of human agency, cultural survival and human suffering are central to the exploration of memory, place and violence developed in this thesis. From this perspective, the thesis takes to task anthropological works on violence that emphasize the routinization of terror and fear for those who live amidst widespread violence. The thesis discusses the multiple ways in which memory is disputed in Colombia and the risks posed by a local reading of violence as intrinsic to the history of the country. It concludes that when individuals are faced with realities such as life and death, the familiar faces of the actors of violence and the weakening of the social and ethical fabric of their communities, they do not stand in definite positions and cannot be defined in simple terms such as victims and perpetrators. Thus, it can be recognized that although violence plays a central role in the Medellin city dwellers processes of identity formation, it does not exhaust these possibilities.

description: This paper develops a Trade Network Game (TNG) that combines evolutionary game play with endogenous partner selection. Resource-constrained buyers and sellers choose and refuse trade partners on the basis of continually updated expected payoffs. Partner selection takes place in accordance with a "deferred choice and refusal" mechanism that is shown to have interesting stability, optimality, and uniqueness properties. The iterated prisoner's dilemma strategies used by buyers and sellers to conduct their trades are evolved over time via a genetic algorithm that biases reproduction in favor of strategies that have been successful in past trades. The TNG is shown to encompass a variety of economic applications, such as job search games, labor markets modelled as assignment games, labor markets with endogenously determined workers and employers, and double auction games. To illustrate the way in which preferential partner selection interacts with game play in the TNG, resulting in the endogenous formation of trade networks, a 5-trader TNG is analyzed in detail.

description: We report spectroscopic and interferometric observations of the high-proper motion double-lined binary system HD 9939, with an orbital period of approximately 25 days. By combining our radial-velocity and visibility measurements we estimate the system physical orbit and derive dynamical masses for the components of $M_A = 1.072 \pm 0.014$ M$_{\sun}$ and $M_B = 0.8383 \pm 0.0081$ M$_{\sun}$; fractional errors of 1.3% and 1.0%, respectively. We also determine a system distance of $42.23 \pm 0.21$ pc, corresponding to an orbital parallax of $π_{\rm orb} = 23.68 \pm 0.12$ mas. The system distance and the estimated brightness difference between the stars in $V$, $H$, and $K$ yield component absolute magnitudes in these bands. By spectroscopic analysis and spectral energy distribution modeling we also estimate the component effective temperatures and luminosities as $T_{\rm eff}^A = 5050 \pm 100$ K and $T_{\rm eff}^B = 4950 \pm 200$ K and $L_A$ = 2.451 $\pm$ 0.041 $L_{\sun}$ and $L_B$ = 0.424 $\pm$ 0.023 $L_{\sun}$. Both our spectral analysis and comparison with stellar models suggest that HD 9939 has elemental abundances near solar values. Further, comparison with stellar models suggests the HD 9939 primary has evolved off the main sequence and appears to be traversing the Hertzsprung gap as it approaches the red giant phase of its evolution. Our measurements of the primary properties provide new empirical constraints on stellar models during this particularly dynamic evolutionary phase. That HD 9939 is currently in a relatively short-lived evolutionary state allows us to estimate the system age as 9.12 $\pm$ 0.25 Gyr. In turn the age and abundance of the system place a potentially interesting, if anecdotal, constraint on star formation in the galactic disk.

Optimal and Suboptimal Detection of Gaussian Signals in Noise: Asymptotic Relative Efficiency

description: The performance of Bayesian detection of Gaussian signals using noisy observations is investigated via the error exponent for the average error probability. Under unknown signal correlation structure or limited processing capability it is reasonable to use the simple quadratic detector that is optimal in the case of an independent and identically distributed (i.i.d.) signal. Using the large deviations principle, the performance of this detector (which is suboptimal for non-i.i.d. signals) is compared with that of the optimal detector for correlated signals via the asymptotic relative efficiency defined as the ratio between sample sizes of two detectors required for the same performance in the large-sample-size regime. The effects of SNR on the ARE are investigated. It is shown that the asymptotic efficiency of the simple quadratic detector relative to the optimal detector converges to one as the SNR increases without bound for any bounded spectrum, and that the simple quadratic detector performs as well as the optimal detector for a wide range of the correlation values at high SNR.

description: Covid-19 has had a big impact on many aspects of our life, including mental health. Since the start of the pandemic, a whole body of Belgian research has been performed on the relation between covid-19 and mental health (care). The mental health & covid-19 working group of the superior health council lists these studies in order to provide advice to policy makers and the general public. The first advisory report focused on international literature on contagious outbreaks, since not many studies on covid-19 and, especially, not many Belgian studies were published yet. This advice can be found here: https://www.health.belgium.be/en/report-9589-mental-health-and-covid-19 As part of the work performed in the first advisory report, the Policy Coordination Working group has asked the Superior Health Council to list all Belgian studies investigating the relation between covid-19 and mental health and/or mental health care and to provide regular updates. The superior Health Council, therefore, started the project of the Belgian mental health data repository. This repository will consist of ongoing studies, preliminary results, accepted and published articles with a Belgian population. For each study, an overview will be given of the authors (including contact details), status (ongoing, published,..), different methodological factors used in the study (e.g. type of population, type of data collection, …) and a short description of the study. The Belgian Mental Health Data Repository will allow for other researchers, policy makers, health care providers and the general public to have a better idea of and easier access to the mental health studies in Belgium. Additionally, more in-depth analyses across studies can be facilitated leading to better insights into the impact of covid-19 on mental health. An update of the living document will be published weekly.

description: We re-consider the self-energy of a nodal (Dirac) fermion in a 2D d-wave superconductor. A conventional belief is that Im Σ(ω, T) \sim max (ω^3, T^3). We show that Σ(ω, k, T) for k along the nodal direction is actually a complex function of ω, T, and the deviation from the mass shell. In particular, the second-order self-energy diverges at a finite T when either ωor k-k_F vanish. We show that the full summation of infinite diagrammatic series recovers a finite result for Σ, but the full ARPES spectral function is non-monotonic and has a kink whose location compared to the mass shell differs qualitatively for spin-and charge-mediated interactions.

description: We present a comprehensive study of internal quality factors in superconducting stub-geometry 3-dimensional cavities made of aluminum. We use wet etching, annealing and electrochemichal polishing to improve the as machined quality factor. We find that the dominant loss channel is split between two-level system loss and an unknown source with 60:40 proportion. A total of 17 cavities of different purity, resonance frequency and size were studied. Our treatment results in reproducible cavities, with ten of them showing internal quality factors above 80 million at a power corresponding to an average of a single photon in the cavity. The best cavity has an internal quality factor of 115 million at single photon level.

They are: (1) a conventional Maxwellian distribution for particle masses around 5 to 9 GeV; (2) a dark matter stream coming from the general direction of Galactic rotation (not the Sagittarius stream). Our idea is based on attributing the DAMA signal to scattering off Na, instead of I, and can be tested in the immediate future by detectors using light nuclei, such as CDMS-II (using Si) and CRESST-II (using O).

description: This paper presents a general C++ platform for the implementation of a trade network game (TNG) that combines evolutionary game play with preferential partner selection. In the TNG, successive generations of resource constrained traders choose and refuse trade partners on the basis of continually updated expected payoffs, engage in risky trades modelled as two-person games, and evolve their trade strategies over time. The modular design of the TNG platform facilitates experimentation with alternative specifications for market structure, trade partner matching, trading, expectation formation, and trade strategy evolution. The TNG platform can be used to study the evolutionary implications of these specifications at three different levels: individual trader attributes; trade network formation; and social welfare.

description: Multiparticle entangled states generated via interaction between narrow-band light and an ensemble of identical two-level atoms are considered. Depending on the initial photon statistics, correlation between atoms and photons can give rise to entangled states of these systems. It is found that the state of any pair of atoms interacting with weak single-mode squeezed light is inseparable and robust against decay. Optical schemes for preparing entangled states of atomic ensembles by projective measurement are described.

description: Machine learning techniques are used for treating jets as images to explore the performance of boosted top quark tagging. Tagging performances are studied in both hadronic and leptonic channels of top quark decay, employing a convolutional neural network (CNN) based technique along with boosted decision trees (BDT). This computer vision approach is also applied to distinguish between left and right polarized top quarks. In this context, an experimentally measurable asymmetry variable is proposed to estimate the polarization. Results indicate that the CNN based classifier is more sensitive to top quark polarization than the standard kinematic variables. It is observed that the overall tagging performance in the leptonic channel is better than the hadronic case, and the former also serves as a better probe for studying polarization.

description: For a postscript copy of this paper, click here. Agent-base computational economics (ACE) is roughly defined as the computational study of economies modelled as evolving decentralized systems of autonomous interacting agents. A key focus of ACE research is understanding how global regularities arise from the bottom up, through the repeated local interactions of autonomous agents channeled through socio-economic institutions, rather than from top down coordination mechanisms such as imposed market clearing constraints or an assumption of single representative agents. This paper discusses how ACE materials have been introduced into graduate-level course in macroeconomic theory over the past several years, using an ACE labor market framework for concrete illustration.

description: A method to estimate the reliability of a perturbative expansion of the stochastic inflationary Langevin equation is presented and discussed. The method is applied to various inflationary scenarios, as large field, small field and running mass models. It is demonstrated that the perturbative approach is more reliable than could be naively suspected and, in general, only breaks down at the very end of inflation.

description: Molti oggi ritengono conclusa la vicenda dello stato moderno In Europa a causa dell’irrompere della ‘globalizzazione’. Tale visione non tiene però adeguatamente conto della vicenda storica cominciata nel 1919 con la Costituzione di Weimar. Questa ha infatti introdotto la nuova stagione della ‘supremazia della costituzione’, pur rimanendo all’interno dell’età moderna. Le nuove costituzioni novecentesche hanno riconosciuto l’importanza della ‘società’ e hanno assunto quale compito quello di mediare tra le contraddizioni sociali. Questa funzione è tutt’ora riconosciuta e apprezzata come valida e in questo senso si può dire che il moderno non sia ancora stato superato dal post-moderno. Se possiamo dire superato lo ‘stato di diritto’ di stampo liberale, è invece ben vivo lo ‘stato costituzionale’ che è ancora e sempre ‘stato moderno’ sia pure con caratteri in parte mutati. Il post-moderno non ha dunque superato il moderno: più semplicemente si può riconoscere che si è andati ‘oltre il Novecento’.

Risk and Uncertainty

description: How large are potential benefits from global risksharing? In order to answer this question we propose a new methodology that is closely connected with the empirical growth literature. We obtain estimates of residual risk (growth uncertainty) at various horizons from regressions of country-specific growth in deviation from world growth on a wide set of variables in the information set. Since this residual risk can be entirely hedged through risksharing, we use it to obtain a measure of the potential welfare gain for a representative country. We find that nations can reap very large benefits from engaging in such risksharing arrangements. Using post-war data, the gain for a 35-year horizon, corresponding to an equivalent permanent increase in consumption, is 6.6% when based on a set of 49 countries, and 1.5% when based on 21 OECD countries. Using historical data from 1870 to 1990, we find that the potential gain for a 120-year horizon ranges from 4.9% for a small set of rich countries to 16.5% for a broad set of 24 countries.

description: This study reports experimental market power and efficiency outcomes for a computational wholesale electricity market operating in the short run under systematically varied concentration and capacity conditions. The pricing of electricity is determined by means of a clearinghouse double auction with discriminatory midpoint pricing. Buyers and sellers use a modified Roth Erev individual reinforcement learning algorithm to determine their price and quantity offers in each auction round. It is shown that high market efficiency is generally attained, and that market microstructure is strongly predictive for the relative market power of buyers and sellers independently of the values set for the reinforcement learning parameters. Results are briefly compared against results from an earlier study in which buyers and sellers instead engage in social mimicry learning via genetic algorithms.
RBF-HS: Recursive Best-First Hitting Set Search
Creators: name: Rodler, Patrick
Publisher: name: arXiv

description: Various model-based diagnosis scenarios require the computation of most preferred fault explanations. Existing algorithms that are sound (i.e., output only actual fault explanations) and complete (i.e., can return all explanations), however, require exponential space to achieve this task. As a remedy, we propose two novel diagnostic search algorithms, called RBF-HS (Recursive Best-First Hitting Set Search) and HBF-HS (Hybrid Best-First Hitting Set Search), which build upon tried and tested techniques from the heuristic search domain. RBF-HS can enumerate an arbitrary predefined finite number of fault explanations in best-first order within linear space bounds, without sacrificing the desirable soundness or completeness properties. The idea of HBF-HS is to find a trade-off between runtime optimization and a restricted space consumption that does not exceed the available memory. In extensive experiments on real-world diagnosis cases we compared our approaches to Reiter's HS-Tree, a state-of-the-art method that gives the same theoretical guarantees and is as general(ly applicable) as the suggested algorithms. For the computation of minimum-cardinality fault explanations, we find that (1) RBF-HS reduces memory requirements substantially in most cases by up to several orders of magnitude, (2) in more than a third of the cases, both memory savings and runtime savings are achieved, and (3) given the runtime overhead is significant, using HBF-HS instead of RBF-HS reduces the runtime to values comparable with HS-Tree while keeping the used memory reasonably bounded. When computing most probable fault explanations, we observe that RBF-HS tends to trade memory savings more or less one-to-one for runtime overheads. Again, HBF-HS proves to be a reasonable remedy to cut down the runtime while complying with practicable memory bounds.
