description: Reid has asked whether hyperbolic manifolds with the same geodesic length spectrum must be commensurable. Building toward a negative answer to this question, we construct examples of hyperbolic 3-manifolds that share an arbitrarily large portion of the length spectrum but are not commensurable. More precisely, for all sufficiently large n, we construct a pair of incommensurable hyperbolic 3-manifolds $N_n$ and $N_n^μ$ whose volume is approximately n and whose length spectra agree up to length n. Both $N_n$ and $N_n^μ$ are built by gluing two standard submanifolds along a complicated pseudo-Anosov map, ensuring that these manifolds have a very thick collar about an essential surface. The two gluing maps differ by a hyper-elliptic involution along this surface. Our proof also involves a new commensurability criterion based on pairs of pants.

Artificial intelligence applied to the automatic analysis of absorption spectra. Objective measurement of the fine structure constant
Creators: name: Bainbridge, Matthew B.

Publisher: name: arXiv
Year: 2016
Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)
subject: FOS: Physical sciences

description: A new and automated method is presented for the analysis of high-resolution absorption spectra. Three established numerical methods are unified into one "artificial intelligence" process: a genetic algorithm (GVPFIT); non-linear least-squares with parameter constraints (VPFIT); and Bayesian Model Averaging (BMA). The method has broad application but here we apply it specifically to the problem of measuring the fine structure constant at high redshift. For this we need objectivity and reproducibility. GVPFIT is also motivated by the importance of obtaining a large statistical sample of measurements of $Δα/α$. Interactive analyses are both time consuming and complex and automation makes obtaining a large sample feasible. In contrast to previous methodologies, we use BMA to derive results using a large set of models and show that this procedure is more robust than a human picking a single preferred model since BMA avoids the systematic uncertainties associated with model choice. Numerical simulations provide stringent tests of the whole process and we show using both real and simulated spectra that the unified automated fitting procedure out-performs a human interactive analysis. The method should be invaluable in the context of future instrumentation like ESPRESSO on the VLT and indeed future ELTs. We apply the method to the $z_{abs} = 1.8389$ absorber towards the $z_{em} = 2.145$ quasar J110325-264515. The derived constraint of $Δα/α= 3.3 \pm 2.9 \times 10^{-6}$ is consistent with no variation and also consistent with the tentative spatial variation reported in Webb et al (2011) and King et al (2012).

description: We derive necessary and sufficient conditions under which a large class of relativistic generalizations of Braginskii's magnetohydrodynamics with shear, bulk, and heat diffusion effects is causal and strongly hyperbolic in the fully nonlinear regime in curved spacetime. We find that causality severely constrains the size of nonideal effects and the onset of kinetic instabilities. Our results are crucial for assessing the regime of validity of fluid dynamical simulations of plasmas near supermassive black holes.

Recording and Describing Poker Hands

Year: 2023
Subjects: subject: Artificial Intelligence (cs.AI)
subject: FOS: Computer and information sciences

description: This paper introduces the Poker Hand History (PHH) file format, designed to standardize the recording of poker hands across different game variants. Despite poker's widespread popularity in the mainstream culture as a mind sport and its prominence in the field of artificial intelligence (AI) research as a benchmark for imperfect information AI agents, it lacks a consistent format that humans can use to document poker hands across different variants that can also easily be parsed by machines. To address this gap in the literature, we propose the PHH format which provides a concise human-readable machine-friendly representation of hand history that comprehensively captures various details of the hand, ranging from initial game parameters and actions to contextual parameters including but not limited to the venue, players, and time control information. In the supplementary, we provide 10,088 hands covering 11 different variants in the PHH format. The full specification is available on https://github.com/uoftcprg/phh-std

description: One of the scenarios for the formation of grand-design spiral arms in disky galaxies involves their interactions with a satellite or another galaxy. Here we consider another possibility, where the perturbation is instead due to the potential of a galaxy cluster. Using $N$-body simulations we investigate the formation and evolution of spiral arms in a Milky Way-like galaxy orbiting a Virgo-like cluster. The galaxy is placed on a few orbits of different size but similar eccentricity and its evolution is followed for 10 Gyr. The tidally induced, two-armed, approximately logarithmic spiral structure forms on each of them during the pericenter passages. The spiral arms dissipate and wind up with time, to be triggered again at the next pericenter passage. We confirm this transient and recurrent nature of the arms by analyzing the time evolution of the pitch angle and the arm strength. We find that the strongest arms are formed on the tightest orbit, however they wind up rather quickly and are disturbed by another pericenter passage. The arms on the most extended orbit, which we analyze in more detail, wind up slowly and survive for the longest time. Measurements of the pattern speed of the arms indicate that they are kinematic density waves. We attempt a comparison with observations by selecting grand-design spiral galaxies in the Virgo cluster. Among those, we find nine examples bearing no signs of recent interactions or the presence of companions. For three of them we present close structural analogues among our simulated spiral galaxies.

On capacity of optical communications over a lossy bosonic channel with a receiver employing the most general coherent electro-optic feedback control

description: We study the problem of designing optical receivers to discriminate between multiple coherent states using coherent processing receivers---i.e., one that uses arbitrary coherent feedback control and quantum-noise-limited direct detection---which was shown by Dolinar to achieve the minimum error probability in discriminating any two coherent states. We first derive and re-interpret Dolinar's binary-hypothesis minimum-probability-of-error receiver as the one that optimizes the information efficiency at each time instant, based on recursive Bayesian updates within the receiver. Using this viewpoint, we propose a natural generalization of Dolinar's receiver design to discriminate $M$ coherent states each of which could now be a codeword, i.e., a sequence of $N$ coherent states each drawn from a modulation alphabet. We analyze the channel capacity of the pure-loss optical channel with a general coherent-processing receiver in the low-photon number regime and compare it with the capacity achievable with direct detection and the Holevo limit (achieving the latter would require a quantum joint-detection receiver). We show compelling evidence that despite the optimal performance of Dolinar's receiver for the binary coherent-state hypothesis test (either in error probability or mutual information), the asymptotic communication rate achievable by such a coherent-processing receiver is only as good as direct detection. This suggests that in the infinitely-long codeword limit, all potential benefits of coherent processing at the receiver can be obtained by designing a good code and direct detection, with no feedback within the receiver.

description: We explore the formation of one-dimensional two-component quantum droplets with intercomponent particle imbalance using an ab-initio many-body method. It is shown that for moderate particle imbalance each component maintains its droplet flat-top or Gaussian type character depending on the intercomponent attraction. Importantly, large particle imbalance leads to a flat-top shape of the majority component with the minority exhibiting spatially localized configurations. The latter imprint modulations on the majority component which become more pronounced for increasing interspecies attraction. The same holds for larger mass or increasing repulsion of the minority species. Such structural transitions are also evident in the underlying two-body correlation functions. To interpret the origin and characteristics of these droplet states we derive an effective model based on the established Lee-Huang-Yang theory providing adequate qualitative analytical predictions even away from its expected parametric region of validity. In contrast, the droplet character is found to vanish in the presence of fermionic minority atoms. Our results pave the way for unveiling complex droplet phases of matter.

This paper introduces a novel approach towards an implementation of head pose estimation techniques for the application of noise control. An existing multi-stage process, which uses convolutional neural network (CNNs), for head pose estimation is modified, implemented, and validated for moving target active noise control. With evaluation and development of application focused methodologies, this paper highlights the  modifications necessary alongside the challenges involving real- time tracking. Utilizing such a method to improve noise comfort  within aircraft cabins through an integrated real-time tracking system allows for the capability to create a zone of quiet bubble around a passenger’s head during their flight time. Through various stand-alone and integrated system tests, the head tracking algorithm proposed shows desirable accuracies, exhibited through low total average % errors. Additionally, the integrated system also shows positive results with low tracking errors alongside effective real-time capabilities. The overall  implementation provides a convincing solution for head- tracking system to be integrated with active noise control for  moving targets within aircraft cabins.

description: With the aim of improving predictions on far infrared (FIR) line emission from Giant Molecular Clouds (GMC), we study the effects of photoevaporation (PE) produced by external far-ultraviolet (FUV) and ionizing (extreme-ultraviolet, EUV) radiation on GMC structure. We consider three different GMCs with mass in the range $M_{\rm GMC} = 10^{3-6}\,\rm{M_{\odot}}$. Our model includes: (i) an observationally-based inhomogeneous GMC density field, and (ii) its time evolution during the PE process. In the fiducial case ($M_{\rm GMC}\approx10^5 M_{\odot}$), the photoevaporation time ($t_{pe}$) increases from 1 Myr to 30 Myr for gas metallicity $Z=0.05-1\,\rm Z_{\odot}$, respectively. Next, we compute the time-dependent luminosity of key FIR lines tracing the neutral and ionized gas layers of the GMCs, ([CII] at $158\,\rm{μm}$, [OIII] at $88\,\rm μm$) as a function of $G_0$, and $Z$ until complete photoevaporation at $t_{pe}$. We find that the specific [CII] luminosity is almost independent on the GMC model within the survival time of the cloud. Stronger FUV fluxes produce higher [CII] and [OIII] luminosities, however lasting for progressively shorter times. At $Z=Z_{\odot}$ the [CII] emission is maximized ($L_{\rm CII}\approx 10^4\,\rm{L_{\odot}}$ for the fiducial model) for $t<1\,\rm{Myr}$ and $\log G_0\geq 3$. Noticeably, and consistently with the recent detection by Inoue et al. (2016) of a galaxy at redshift $z\approx 7.2$, for $Z\leq 0.2\,\rm{Z_{\odot}}$ the [OIII] line might outshine [CII] emission by up to $\approx 1000$ times. We conclude that the [OIII] line is a key diagnostic of low metallicity ISM, especially in galaxies with very young stellar populations.

description: The failure to find evidence for elementary particles that could serve as the constituents of dark matter brings to mind suggestions that dark matter might consist of massive compact objects (MACHOs). In particular, it has recently been argued that MACHOs with masses > 15 solar masses may have been prolifically produced at the onset of the big bang. Although a variety of astrophysical signatures for primordial MACHOs with masses in this range have been discussed in the literature, we favor a strategy that uses the potential for gravitational microlensing of stars outside our galaxy to directly detect the presence of MACHOs in the halo of our galaxy. We point out that the effect of the motion of the Earth on the shape of the microlensing brightening curves provides a promising approach to confirming over the course of next several years that dark matter consists of MACHOs.

Year: 2022

In this paper, estimation of the applied force on a planar catheter is considered. An image processing approach has been chosen as the most suitable tool. For this purpose, we create a comprehensive database of catheters with different shapes and operating forces. Using image processing algorithms, position data for the catheters' outer, middle, and inner layers in this database are obtained. Finally, using curve fitting, an exponential mathematical function is accepted for the middle layer of each catheter. Feeding this data into different machine learning algorithms, force estimation is obtained with a mean average error of 0.52 N. Later, the force applied to a tendon catheter is estimated using the SOFA framework and deep learning techniques, directing the research into a reliable applied force estimation.

Year: 2016
Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: We review recent experiments on the Bose-Einstein condensation of photons in a dye-filled optical microresonator. The most well-known example of a photon gas, photons in blackbody radiation, does not show Bose-Einstein condensation. Instead of massively populating the cavity ground mode, photons vanish in the cavity walls when they are cooled down. The situation is different in an ultrashort optical cavity imprinting a low-frequency cutoff on the photon energy spectrum that is well above the thermal energy. The latter allows for a thermalization process in which both temperature and photon number can be tuned independently of each other or, correspondingly, for a non-vanishing photon chemical potential. We here describe experiments demonstrating the fluorescence-induced thermalization and Bose-Einstein condensation of a two-dimensional photon gas in the dye microcavity. Moreover, recent measurements on the photon statistics of the condensate, showing Bose-Einstein condensation in the grandcanonical ensemble limit, will be reviewed.

description: Practical implementation of many quantum algorithms known today is limited by the coherence time of the executing quantum hardware and quantum sampling noise. Here we present a machine learning algorithm, NISQRC, for qubit-based quantum systems that enables inference on temporal data over durations unconstrained by decoherence. NISQRC leverages mid-circuit measurements and deterministic reset operations to reduce circuit executions, while still maintaining an appropriate length persistent temporal memory in quantum system, confirmed through the proposed Volterra Series analysis. This enables NISQRC to overcome not only limitations imposed by finite coherence, but also information scrambling in monitored circuits and sampling noise, problems that persist even in hypothetical fault-tolerant quantum computers that have yet to be realized. To validate our approach, we consider the channel equalization task to recover test signal symbols that are subject to a distorting channel. Through simulations and experiments on a 7-qubit quantum processor we demonstrate that NISQRC can recover arbitrarily long test signals, not limited by coherence time.

description: The long-standing challenge of creating a Milky Way-like disk galaxy from cosmological simulations has motivated significant developments in both numerical methods and physical models in recent years. We investigate these two fundamental aspects in a new comparison project using a set of cosmological hydrodynamic simulations of the formation and evolution of a Milky Way-size galaxy. In this study, we focus on the comparison of two particle-based hydrodynamics methods: the improved smoothed particle hydrodynamics (SPH) code Gadget, and the Lagrangian Meshless Finite-Mass (MFM) code GIZMO. All the simulations in this paper use the same initial conditions and physical models, which include physics of both dark matter and baryons, star formation, "energy-driven" outflow, metal-dependent cooling, stellar evolution and metal enrichment from supernovae. We find that both numerical schemes produce a late-type galaxy with extended gaseous and stellar disks. However, notable differences are present in a wide range of galaxy properties and their evolution, including star formation history, gas content, disk structure and kinematics. In particular, there is significant difference in gas properties and their evolution between the two simulations. Compared to GIZMO, Gadget simulation produces a larger fraction of cold, dense gas at high redshift which fuels rapid star formation and results in a higher stellar mass by $20\%$ and a lower gas fraction by $10\%$ at $z = 0$, and the resulting gas disk is smoother and more coherent in rotation due to damping of turbulent motion by the numerical viscosity in SPH, in contrast to the GIZMO simulation which shows more prominent spiral structure. Given its better convergence properties and lower computational cost, we argue that MFM method is a promising alternative to the widely used SPH in cosmological hydrodynamic simulations.

Hydrogels have attracted the attention of growing fields such as tissue engineering because of their unique characteristics such as biocompatibility with several cell types  and tunable properties. In our study, we selected poly N- Isopropylacrylamide (pNIPAM) based hydrogel as this material  has low critical solution temperature close to the human physiological temperature. However, more information is required on how manufacturing processes can affect the mechanical behaviour of the printed structure. In-vat polymerization processes stand out among additive manufacturing processes capable of efficiently producing NIPAM-based hydrogels. Among them, the digital light processing (DLP) process allows for its high resolution, printing speed, dimensional and spatial control of the printing process, isotropy of the layers and reduced process cost when compared to other vat polymerization processes. This work is dedicated to investigating how crosslinking rate and thickness of 4D DLP printed NIPAM based hydrogels affect their folding behaviour. Two different printing approaches were investigated: (i) a constant thickness exposed to constant light intensity over all the sample surfaces, and (ii) a constant thickness but exposed to a gradient light intensity over the sample surface. Results show that printed sample thickness plays a key role in the bending of the samples. Samples smaller than 0.25 mm bend uncontrollably and erratically, samples between 0.25 mm and 0.55 mm bend longitudinally, obtaining the final shape of a cylinder, while samples thicker than 0.55 mm are unable to bend. The variation of light intensity generates variations in the crosslinking rate of the samples, where regions with higher crosslinking rates are more rigid and with less bending capacity.

A new eye-in-hand/eye-to-hand cooperated visual system in peg-in-hole microassembly work is assisted by coordinate-based augmented reality (AR) through three dimensional (3D)-hybrid visual calibration and servo. The 3D hybrid visual calibration is to combine real camera’s intrinsic  parameters and virtual camera’s extrinsic parameters in step- wise visual calibration. The detecting and tracking of image  feature points are undertaken by utilizing marker and estimator. By employing 3D model and ray casting, the 3D coordinates on the matching rod, including the center of mating hole, and corner points of supporting block correspondent to the 2D virtual image points are extracted. Regarding the image viewed by the real and virtual cameras in AR, a calibrated virtual camera is utilized to track the coordinates of real mating hole and supporting block. The effectiveness of coordinate-based AR technology by the eye-in-hand configuration is tested in the alignment between micropeg and mating hole for inserting a micropeg of diameter 80 μm with length 1~1.4 mm into a mating rod with 100 μm hole.

description: In the modern market economy, there are various organizational and legal forms of enterprises that provide for the security of society. But managers of large businesses rarely think about the need for competent personnel management and personnel analysis of such a system. Although it is the high human resources potential that is the key to the efficiency of the enterprise and its efficiency. In the article, the authors use the method of a wide range of scientific methods: comparison, general method, structural analysis method, comparison method, analysis of financial ratios, etc. The article presents a toolkit that has proven to be effective and has already been tested at domestic and international enterprises to improve the efficiency of both the existing management system and its provision with highly professional personnel. Based on this, an analysis of the activities of several individual enterprises of the Sverdlovsk region was carried out. As a result, a number of existing problems that negatively affect the activities of small businesses are given and described. Proposals for solving identified problems and minimizing risks have been developed. Attention is paid to the analysis of methods for improving the efficiency of personnel activities. The processes of implementation and regulation of document circulation, including the electronic document management system (EDMS) in the personnel management system, are considered, the directions for its improvement are determined, which, as a result, will improve the performance discipline and increase the efficiency of an individual enterprise. The calculations of the costs of implementation, the efficiency of the EDMS are given. In conclusion, the article concludes that the recommended measures will help improve the personnel and documentation support for personnel management, as well as allow an individual enterprise to take a more stable and competitive position in the market.

description: In order to fully harness the potential of machine learning, it is crucial to establish a system that renders the field more accessible and less daunting for individuals who may not possess a comprehensive understanding of its intricacies. The paper describes the design of a system that integrates AutoML, XAI, and synthetic data generation to provide a great UX design for users. The system allows users to navigate and harness the power of machine learning while abstracting its complexities and providing high usability. The paper proposes two novel classifiers, Logistic Regression Forest and Support Vector Tree, for enhanced model performance, achieving 96\% accuracy on a diabetes dataset and 93\% on a survey dataset. The paper also introduces a model-dependent local interpreter called MEDLEY and evaluates its interpretation against LIME, Greedy, and Parzen. Additionally, the paper introduces LLM-based synthetic data generation, library-based data generation, and enhancing the original dataset with GAN. The findings on synthetic data suggest that enhancing the original dataset with GAN is the most reliable way to generate synthetic data, as evidenced by KS tests, standard deviation, and feature importance. The authors also found that GAN works best for quantitative datasets.

description: The high energy (Regge) limit provides a playground for understanding all loop structures of scattering amplitudes, and plays an important role in the description of many phenomenologically relevant cross-sections. While well understood in the planar limit, the structure of non-planar corrections introduces many fascinating complexities, for which a general organizing principle is still lacking. We study the structure of multi-reggeon exchanges in the context of the effective field theory for forward scattering, and derive their factorization into collinear operators (impact factors) and soft operators. We derive the structure of the renormalization group consistency equations in the effective theory, showing how the anomalous dimensions of the soft operators are related to those of the collinear operators, allowing us to derive renormalization group equations in the Regge limit purely from a collinear perspective. The rigidity of the consistency equations provides considerable insight into the all orders organization of Regge amplitudes in the effective theory, as well as its relation to other approaches. Along the way we derive a number of technical results that improve the understanding of the effective theory. We illustrate this collinear perspective by re-deriving all the standard BFKL equations for two-Glauber exchange from purely collinear calculations, and we show that this perspective provides a number of conceptual and computational advantages as compared to the standard view from soft or Glauber physics. We anticipate that this formulation in terms of collinear operators will enable a better understanding of the relation between BFKL and DGLAP in gauge theories, and facilitate the analysis of renormalization group evolution equations describing Reggeization beyond next-to-leading order.

Scattering theory on surface Majorana fermions by an impurity in 3He-B

description: We have formulated the scattering theory on Majorana fermions emerging in the surface bound state of the superfluid $^3$He B-phase ($^3$He-B) by an impurity. By applying the theory to the electron bubble, which is regarded as the impurity, trapped below a free surface of $^3$He-B, the observed mobility of the electron bubble [Ikegami et al., J. Phys. Soc. Jpn. 82, 124607 (2013)] is quantitatively reproduced. The mobility is suppressed in low temperatures from the expected value in the bulk $^3$He-B by the contribution from the surface Majorana fermions. By contrast, the mobility does not depend on trapped depth of the electron bubble in spite of the spatial variation of the wave function of the surface Majorana fermions. Our formulated theory demonstrates the depth independent mobility by considering intermediate states in the scattering process. Therefore, we conclude that the experiment has succeeded in observing Majorana fermions in the surface bound state.
