description: We discuss the relations between restricted Boltzmann machine (RBM) states and the matrix product states (MPS) for the ground states of 1D translational invariant stabilizer codes. A generic translational invariant and finitely connected RBM state can be expressed as an MPS, and the matrices of the resulting MPS are of rank 1. We dub such an MPS as an RBM-MPS. This provides a necessary condition for exactly realizing a quantum state as an RBM state, if the quantum state can be written as an MPS. For generic 1D stabilizer codes having a non-degenerate ground state with periodic boundary condition, we obtain an expression for the lower bound of their MPS bond dimension, and an upper bound for the rank of their MPS matrices. In terms of RBM, we provide an algorithm to derive the RBM for the cocycle Hamiltonians whose MPS matrices are proved to be of rank 1. Moreover, the RBM-MPS produced by our algorithm has the minimal bond dimension. A family of examples is provided to explain the algorithm. We finally conjecture that these features hold true for all the 1D stabilizer codes having a non-degenerate ground state with periodic boundary condition, as long as their MPS matrices are of rank 1.

description: We study numerically the magnetic properties (magnetization and magnetoresistance) of ultra-thin magnetic films (Fe/Cr) grown following the Fibonacci sequence. We use a phenomenological model which includes Zeeman, cubic anisotropy, bilinear and biquadratic exchange energies. Our physical parameters are based on experimental data recently reported, which contain biquadratic exchange coupling with magnitude comparable to the bilinear exchange coupling. When biquadratic exchange coupling is sufficiently large a striking self-similar pattern emerges.

description: We dispersively couple a single trapped ion to an optical cavity to extract information about the cavity photon-number distribution in a nondestructive way. The photon-number-dependent AC-Stark shift experienced by the ion is measured via Ramsey spectroscopy. We use these measurements first to obtain the ion-cavity interaction strength. Next, we reconstruct the cavity photon-number distribution for coherent states and for a state with mixed thermal-coherent statistics, finding overlaps above 99% with the calibrated states.

How do referees integrate evaluation criteria into their overall judgment? Evidence from grant peer review
Creators: name: Hug, Sven E.
Publisher: name: arXiv
Year: 2023
Subjects: subject: Digital Libraries (cs.DL)
subject: FOS: Computer and information sciences

description: Little is known whether peer reviewers use the same evaluation criteria and how they integrate the criteria into their overall judgment. This study therefore proposed two assessment styles based on theoretical perspectives and normative positions. According to the case-by-case style, referees use many and different criteria, weight criteria on a case-by-case basis, and integrate criteria in a complex, non-mechanical way into their overall judgment. According to the uniform style, referees use a small fraction of the available criteria, apply the same criteria, weight the criteria in the same way, and integrate the criteria based on simple rules (i.e., fast-and-frugal heuristics). These two styles were examined using a unique dataset from a career funding scheme that contained a comparatively large number of evaluation criteria. A heuristic (fast-and-frugal trees) and a complex procedure (logistic regression) were employed to describe how referees integrate the criteria into their overall judgment. The logistic regression predicted the referees' overall assessment with high accuracy and slightly more accurately than the fast-and-frugal trees. Overall, the results of this study support the uniform style but also indicate that the uniform style needs to be revised as follows: referees use many criteria and integrate the criteria using complex rules. However, and most importantly, the revised style could describe most - but not all - of the referees' judgments. Future studies should therefore examine how referees' judgments can be characterized in those cases where the uniform style failed. Moreover, the evaluation process of referees should be studied in more empirical and theoretical detail.

description: This paper assesses the profitability of industrial potato production in Poland. The studies indicated changes on the market concerning industrial potatoes and involved an assessment of the area of cultivation and level of production achieved in comparison to other EU countries. Farm profitability is determined based on the calculated gross margin from which its agricultural income was estimated. An analysis of the profitability of assets and sales was also prepared. Changes in potato production and crop yield as well as the general situation on the potato market were analysed. It was shown that the purchase price of potatoes and potato crop cultivation materials are the most important factors contributing to the profitability of potato production. Research was carried out at a specifically selected family farm specializing in potato production. It was observed that the farmer did not pursue drastic reductions in production costs, as this would have led to a decrease in income and profitability. However, their strategy did allow for a sufficiently high gross margin to be obtained. The gross margin from potato production that was obtained in 2014-2018 was positive, and higher than the average in their province.

description: Using the fluctuation exchange approximation of the one band Hubbard model, we discuss the origin of the changing Fermi surface volume in underdoped cuprate systems due to the transfer of occupied states from the Fermi surface to its shadow, resulting from the strong dynamical antiferromagnetic short range correlations. The momentum and temperature dependence of the quasi particle scattering rate shows unusual deviations from the conventional Fermi liquid like behavior. Their consequences for the changing Fermi surface volume are discussed. Here, we investigate in detail which scattering processes might be responsible for a violation of the Luttinger theorem. Finally, we discuss the formation of hole pockets near half filling.

description: During the last 30 years, stimulated by the quest to build superconducting quantum processors, a theory of quantum electrical circuits has emerged and this theory goes under the name of circuit quantum electrodynamics or circuit-QED. The goal of the theory is to provide a quantum description of the most relevant degrees of freedom. The central objects to be derived and studied are the Lagrangian and the Hamiltonian governing these degrees of freedom. Central concepts in classical network theory such as impedance and scattering matrices can be used to obtain the Hamiltonian and Lagrangian description for the lossless (linear) part of the circuits. Methods of analysis, both classical and quantum, can also be developed for nonreciprocal circuits. These lecture notes aim at giving a pedagogical overview of this subject for theoretically-oriented Master or PhD students in physics and electrical engineering, as well as Master and PhD students who work on experimental superconducting quantum devices and wish to learn more theory.

description: We numerically investigate the supercooled dynamics of two simple model liquids exploiting the partition of the multi-dimension configuration space in basins of attraction of the stationary points (inherent saddles) of the potential energy surface. We find that the inherent saddles order and potential energy are well defined functions of the temperature T. Moreover, decreasing T, the saddle order vanishes at the same temperature (T_MCT) where the inverse diffusivity appears to diverge as a power law. This allows a topological interpretation of T_MCT: it marks the transition from a dynamics between basins of saddles (T>T_MCT) to a dynamics between basins of minima (T

description: We introduce a new continuous cellular automaton that presents self-organized criticality. It is one-dimensional, totally deterministic, without any kind of embedded randomness, not even in the initial conditions. This system is in the same universality class as the Oslo rice pile system, boundary driven interface depinning and the train model for earthquakes. Although the system is chaotic, in the thermodynamic limit chaos occurs only in a microscopic level.

description: Leaky boundary conditions in asymptotically AdS spacetimes are relevant to discuss black hole evaporation and the evolution of the Page curve via the island formula. We explore the consequences of leaky boundary conditions on the one-loop partition function of gravity. We focus on JT gravity minimally coupled to a scalar field whose normalizable and non-normalizable modes are both turned on, allowing for leakiness through the AdS boundary. Classically, this yields a flux-balance law relating the scalar news to the time derivative of the mass. Semi-classically, we argue that the usual diffeomorphism-invariant measure is ill-defined, suggesting that the area-non-preserving diffeomorphisms are broken at one loop. We calculate the associated anomaly and its implication on the gravitational Gauss law. Finally, we generalize our arguments to higher dimensions and dS.

description: We investigate the dynamics of two-dimensional site-diluted Ising antiferromagnets. In an external magnetic field these highly disordered magnetic systems have a domain structure which consists of fractal domains with sizes on a broad range of length scales. We focus on the dynamics of these systems during the relaxation from a long-range ordered initial state to the disordered fractal-domain state after applying an external magnetic field. The equilibrium state with applied field consists of fractal domains with a size distribution which follows a power law with an exponential cut-off. The dynamics of the system can be understood as a growth process of this fractal-domain state in such a way that the equilibrium distribution of domains develops during time. Following these ideas quantitatively we derive a simple description of the time dependence of the order parameter. The agreement with simulations is excellent.

The definition is suitable for any regularization scheme and clearly states to what extent the classical equations of motion should be used, thus resolving existing controversies surrounding previous proposals. Additionally, we exhibit the link between our definition of the anomaly and the functional Jacobian arising from a Weyl transformation.

description: Radial velocity (RV) surveys have detected hundreds of exoplanets through their gravitational interactions with their host stars. Some will be transiting, but most lack sufficient follow-up observations to confidently detect (or rule out) transits. We use published stellar, orbital, and planetary parameters to estimate the transit probabilities for nearly all exoplanets that have been discovered via the RV method. From these probabilities, we predict that $25.5^{+0.7}_{-0.7}$ of the known RV exoplanets should transit their host stars. This prediction is more than double the amount of RV exoplanets that are currently known to transit. The Transiting Exoplanet Survey Satellite (TESS) presents a valuable opportunity to explore the transiting nature of many of the known RV exoplanet systems. Based on the anticipated pointing of TESS during its two-year primary mission, we identify the known RV exoplanets that it will observe and predict that $11.7^{+0.3}_{-0.3}$ of them will have transits detected by TESS. However, we only expect the discovery of transits for $\sim$3 of these exoplanets to be novel (i.e., not previously known). We predict that the TESS photometry will yield dispositive null results for the transits of $\sim$125 RV exoplanets. This will represent a substantial increase in the effort to refine ephemerides of known RV exoplanets. We demonstrate that these results are robust to changes in the ecliptic longitudes of future TESS observing sectors. Finally, we consider how several potential TESS extended mission scenarios affect the number of transiting RV exoplanets we expect TESS to observe.

description: Learning for control is capable of acquiring controllers in novel task scenarios, paving the path to autonomous robots. However, even with recent advances in the field, the problem of automatically designing and learning controllers for complex robots remains a challenging problem. Typical learning approaches can be prohibitively expensive in terms of robot experiments, and policies learned in simulation do not transfer, due to modelling inaccuracies. This encourages learning information from simulation that has a higher chance of transferring to hardware. In this thesis, we explore methods that learn from simulation to improve performance on actual robots. One way to improve sample-efficiency is through parametric expert-designed controllers. Such controllers are popular in robotics but need re-learning of parameters for new task scenarios. In this context, Bayesian optimization has emerged as a promising approach for automatically learning controller parameters. However, when performing Bayesian optimization on hardware for high-dimensional policies,
sample-efficiency can still be an issue. We develop an approach that utilizes simulation to map the original parameter space into a domain-informed space. During
Bayesian optimization, similarity between controllers is now calculated in this transformed space, thus informing distances on hardware with behavior in simulation.
We propose two ways of building this transformation, hand-designed features based on knowledge of human walking and using neural networks to extract this information automatically. Our hardware experiments on the ATRIAS robot, and simulation experiments on a 7-link biped model, show that these feature transforms capture important aspects of walking and accelerate learning on hardware
and perturbed simulation, as compared to traditional Bayesian optimization and other learning methods.
Another question arises: What if the simulation significantly differs from hardware? To answer this, we create increasingly approximate simulators and study the
effect of increasing simulation-hardware mismatch on the performance of Bayesian optimization. We also compare our approach to other approaches from literature, and find it to be more reliable, especially in cases of high mismatch.
An alternative to directly optimizing policies on hardware is to learn robust policies in simulation that can be implemented on hardware. We study the effect of different
policy structures on the robustness of very high-dimensional neural network policies. Our experiments on the ATRIAS robot show that neural network policies with an expert-designed structure have a higher rate of transfer between simulation and hardware than unstructured policies.

description: Dense stellar clusters are natural sites for the origin and evolution of exotic objects such as relativistic binaries (potential gravitational wave sources), blue stragglers, etc. We investigate the secular dynamics of a binary system driven by the global tidal field of an axisymmetric stellar cluster in which the binary orbits. In a companion paper (Hamilton & Rafikov 2019a) we developed a general Hamiltonian framework describing such systems. The effective (doubly-averaged) Hamiltonian derived there encapsulates all information about the tidal potential experienced by the binary in its orbit around the cluster in a single parameter $Γ$. Here we provide a thorough exploration of the phase-space of the corresponding secular problem as $Γ$ is varied. We find that for $Γ> 1/5$ the phase-space structure and the evolution of binary orbital element are qualitatively similar to the Lidov-Kozai problem. However, this is only one of four possible regimes, because the dynamics are qualitatively changed by bifurcations at $Γ= 1/5,0,-1/5$. We show how the dynamics are altered in each regime and calculate characteristics such as secular evolution timescale, maximum possible eccentricity, etc. We verify the predictions of our doubly-averaged formalism numerically and find it to be very accurate when its underlying assumptions are fulfilled, typically meaning that the secular timescale should exceed the period of the binary around the cluster by $\gtrsim 10-10^2$ (depending on the cluster potential and binary orbit). Our results may be relevant for understanding the nature of a variety of exotic systems harboured by stellar clusters.

Channel Sensing in Molecular Communications with Single Type of Ligand Receptors

Year: 2019
Subjects: subject: Emerging Technologies (cs.ET)

description: Molecular Communications (MC) uses molecules as information carriers between nanomachines. MC channel in practice can be crowded with different types of molecules, i.e., ligands, which can have similar binding properties causing severe cross-talk on ligand receptors. Simultaneous sensing of multiple ligand types provides opportunities for eliminating interference of external molecular sources and multi-user interference (MUI), and developing new multiple access techniques for MC nanonetworks. In this paper, we investigate channel sensing methods that use only a single type of receptors and exploit the amount of time receptors stay bound and unbound during ligand-receptor binding reaction to concurrently estimate the concentration of multiple types of ligands. We derive the Cramér-Rao Lower Bound (CRLB) for multi-ligand estimation, and propose practical and low-complexity suboptimal estimators for channel sensing. We analyze the performance of the proposed methods in terms of normalized mean squared error (NMSE), and show that they can efficiently estimate the concentration of ligands up to $10$ different types with an average NMSE far below $10^{-2}$. Lastly, we propose a synthetic receptor design based on modified kinetic proofreading (KPR) scheme to sample the unbound and bound time durations, and a Chemical Reaction Network (CRN) to perform the required computations in synthetic cells.

description: Purpose of ProjectCognitive errors contribute to erroneous diagnoses. The use of metacognitive aids can help in decreasing the non-rational factors associated with cognitive errors. This study was aimed at helping anesthesia providers become aware of the decision-making style that they identify with and to provide them with a metacognitive aid that will help to maintain rational thinking. Methodology Anesthesiologists (n = 3), Certified Registered Nurse Anesthetists (CRNA) (n= 21), and Resident Registered Nurse Anesthetists (RRNA) (n= 42) participated in this study. A questionnaire, with the decision styles scale, was given via Qualtrics, followed by an educational lecture on the types of decision-making processes and common cognitive errors existing in anesthesia practice. Following the lecture, a badge buddy with a metacognitive aid, TWED checklist, was made available to each participant.Results The Chi-Squared Test was used to determine any association between confidence levels and type of provider. Only 1 of 4 questions produced statistically significant data (p > 0.1). Implications for PracticeUtilization of metacognitive aids will result in an increase of awareness of possible cognitive errors. From this study, providers were made aware of the non-rational factors that can potentially negatively impact patient safety throughout the perioperative period and methods that can be used to mitigate these factors.

description: Humans convey their thoughts, emotions, and intentions through a concert of social displays: voice, facial expressions, hand gestures, and body posture, collectively referred to as social signals. Despite advances in machine perception, machines are unable to discern the subtle
and momentary nuances that carry so much of the information and context of human communication.
The encoding of conveyed information by social signals, particularly in nonverbal communication, is still poorly understood, and thus it is unclear how to teach machines to
use such social signals to make them collaborative partners rather than tools that we use. A major obstacle to scientific progress in this direction is the inability to sense and measure the broad spectrum of behavioral cues in groups of interacting individuals, which hinders applying computational methods to model and understand social signals.
In this thesis, we explore new approaches in sensing, measuring, and modeling social signals to ultimately endow machines with the ability to interpret nonverbal communication. This thesis starts by describing our exploration in building a massively multiview
sensor system, the Panoptic Studio, that can capture a broad spectrum of human social signaling—including voice, social formations, facial expressions, hand gestures, and body postures—among groups of multiple people. Second, leveraging this system equipped with more than 500 synchronized cameras, we then present a method to measure the subtle 3D movements of anatomical keypoints in face-to-face interaction, providing a new opportunity
to computationally study social signals. In the last part of this thesis, we present a social signal prediction task to model nonverbal communication in a data-driven manner. We establish a new large-scale corpus from hundreds of participants containing various channels of social signal measurements. Leveraging this dataset, we verify that the social signals are predictive each other with strong correlations.

description: Building on the foundation work of Brown, Milton and Torquato, we present a tractable approach to analyse the effective permittivity of anisotropic two-phase structures. This methodology accounts for successive dipolar interactions, providing a recurrent series expansion of the effective permittivity to arbitrary order. Within this framework, we also demonstrate a progressive method to determine tight bounds that converge towards the exact solution. We illustrate the utility of these methods by using ensemble averaging to determine the micro-structural parameters of anisotropic level-cut Gaussian fields. We find that the depolarization factor of these structures is equivalent to that of an isolated ellipse with the same stretchingratio, and discuss the contribution of the fourth order term to the exact anisotropy.

description: We study the nature of charm degrees of freedom in hot strong interaction matter by performing lattice QCD calculations of the second and fourth-order cumulants of charm fluctuations, and their correlations with net baryon number, electric charge and strangeness fluctuations. We show that below the chiral crossover temperature thermodynamics of charm can be very well understood in terms of charmed hadrons. Above the chiral transition charm quarks show up as new degrees of freedom contributing to the partial charm pressure. However, up to temperatures as high as 175 MeV charmed hadron-like excitations provide a significant contribution to the partial charm pressure.

Year: 2021

description: Purpose of ProjectCognitive errors contribute to erroneous diagnoses. The use of metacognitive aids can help in decreasing the non-rational factors associated with cognitive errors. This study was aimed at helping anesthesia providers become aware of the decision-making style that they identify with and to provide them with a metacognitive aid that will help to maintain rational thinking. Methodology Anesthesiologists (n = 3), Certified Registered Nurse Anesthetists (CRNA) (n= 21), and Resident Registered Nurse Anesthetists (RRNA) (n= 42) participated in this study. A questionnaire, with the decision styles scale, was given via Qualtrics, followed by an educational lecture on the types of decision-making processes and common cognitive errors existing in anesthesia practice. Following the lecture, a badge buddy with a metacognitive aid, TWED checklist, was made available to each participant.Results The Chi-Squared Test was used to determine any association between confidence levels and type of provider. Only 1 of 4 questions produced statistically significant data (p > 0.1). Implications for PracticeUtilization of metacognitive aids will result in an increase of awareness of possible cognitive errors. From this study, providers were made aware of the non-rational factors that can potentially negatively impact patient safety throughout the perioperative period and methods that can be used to mitigate these factors.

description: Arbitrarily large ground state population is a general property of any ideal bose gas when conditions of degeneracy are satisfied; it occurs at any dimension D. For $D = 1$, the condensation is diffuse, at $D = 2$ it is a sort of quasi-condensate. The discussion is made by following a microscopic approach and for finite systems. Some astrophysical consequences are discussed, as well as the temperature-dependent mass case.

description: State-of-the-art distributed algorithms for reinforcement learning rely on multiple independent agents, which simultaneously learn in parallel environments while asynchronously updating a common, shared policy. Moreover, decentralized control architectures (e.g., CPGs) can coordinate spatially distributed portions of an articulated robot to achieve system-level objectives. In this work, we investigate the relationship between distributed learning and decentralized control by learning decentralized control policies for the locomotion of articulated robots in challenging environments. To this end, we present an approach that leverages the structure of the asynchronous advantage actor-critic (A3C) algorithm to provide a natural means of learning decentralized control policies on a single articulated robot. Our primary contribution shows individual agents in the A3C algorithm can be defined by independently controlled portions of the robot's body, thus enabling distributed learning on a single robot for efficient hardware implementation. We present results of closed-loop locomotion in unstructured terrains on a snake and a hexapod robot, using decentralized controllers learned offline and online respectively.

Effective size of a parity-time symmetric dimer

description: Parity-time (PT) symmetric dimers were introduced to highlight the unusual properties of non-Hermitian systems that are invariant after a combined parity and time reversal operation. They are also the building blocks of a variety of symmetry and topologically protected structures, especially on integrated photonic platforms. As the name suggests, it consists of two coupled oscillators, which can be optical, mechanical, electronic, and so on in nature. In this article, we show that its effective size, defined by the number of lattice sites inversely proportional to the lattice momentum, is surprisingly three instead of two from the perspective of energy quantization. More specifically, we show analytically that the complex energy levels of a one-dimensional concatenated chain with $N$ PT-dimers are determined by a system size of $1+2N$, which reduces to three in the case of a single PT-dimer. We note that while energy quantization conditions were established in various non-Hermitian systems, exact and explicitly quantized complex energies as reported here are still scarce. In connection, we also discuss the other symmetries of a PT-dimer and concatenated PT-dimer chain, including non-Hermitian particle-hole symmetry and chiral symmetry.

description: Supersymmetry, a symmetry between fermions and bosons, provides a promising extension of the standard model but is still lack of experimental evidence. Recently, the interest in supersymmetry arises in the condensed matter community owing to its potential emergence at the continuous quantum phase transition. In this work, we demonstrate that 2+1D supersymmetry, relating massive Majorana and Ising fields, might emerge at the first-order quantum phase transition of the Ising magnetization by tuning a single parameter. Although the emergence of the SUSY is only allowed in a finite range of scales due to the existence of relevant masses, the scale range can be large when the masses before scaling are small. We show that the emergence of supersymmetry is accompanied by a topological phase transition for the Majorana field, where its non-zero mass changes the sign but keeps the magnitude. An experimental realization of this scenario is proposed using the surface state of a 3+1D time-reversal invariant topological superconductor with surface magnetic doping.

description: We point out that two different definitions of the superfluid density - through statistical response to static gauge phase and through dynamic response to altering gauge phase - yield, generally speaking, different quantities in $d<3$. The physics leading to this difference is associated with the equilibrium statistics of supercurrent states. Some experimentally observable consequences of this fact are discussed.
