Role of time reversal symmetry and tilting in circular photogalvanic responses

description: We study the role of time reversal symmetry (TRS) in the circular photogalvanic (CPG) responses considering chiral Weyl semimetal (WSM) while a quantized CPG response is guaranteed by broken of both inversion symmetry (IS) and mirror symmetries. The TRS broken WSM yields one left and one right chiral Weyl nodes (WNs) while there are two left and right chiral WNs for TRS invariant WSM. We show that these features can potentially cause the quantization of CPG response at higher values compared to the topological charge of the underlying WSM. This is further supported by the fact that Berry curvature and velocity behave differently whether the system preserves or breaks the TRS. We find the CPG responses for TRS invariant type-II WSM to be quantized at two and four times the topological charge of the activated WNs while the chemical potential are respectively chosen in the vicinity of energies associated with left and right chiral WNs. By contrast, irrespective of the above choice of the chemical potential, the quantization in CPG response is directly given by the topological charge of the activated WNs for TRS broken case. Interestingly, we notice non-quantized peak in CPG response when energies of WNs associated with opposite chiralities are close to each other as it is the case for TRS invariant type-I WSM considered here. Moreover, we show that the tilt can significantly modify the CPG response as velocity in the tilt direction changes which enters into the CPG tensor through the Fermi distribution function. Given these exciting outcomes, the second order CPG response emerges as a useful indicator to characterize the system under consideration. Furthermore, we investigate the momentum resolved structure of CPG response to relate with the final results and strengthen our analysis from the perspective of the lattice models.

description: A generalization of the matrix model idea to quantum gravity in three and higher dimensions is known as group field theory (GFT). In this paper we study generalized GFT models that can be used to describe 3D quantum gravity coupled to point particles. The generalization considered is that of replacing the group leading to pure quantum gravity by the twisted product of the group with its dual --the so-called Drinfeld double of the group. The Drinfeld double is a quantum group in that it is an algebra that is both non-commutative and non-cocommutative, and special care is needed to define group field theory for it. We show how this is done, and study the resulting GFT models. Of special interest is a new topological model that is the ``Ponzano-Regge'' model for the Drinfeld double. However, as we show, this model does not describe point particles. Motivated by the GFT considerations, we consider a more general class of models that are defined using not GFT, but the so-called chain mail techniques. A general model of this class does not produce 3-manifold invariants, but has an interpretation in terms of point particle Feynman diagrams.

Robotic Pick-and-Place With Uncertain Object Instance Segmentation and Shape Completion
Creators: name: Gualtieri, Marcus

Publisher: name: arXiv
Year: 2020
Subjects: subject: Robotics (cs.RO)
subject: FOS: Computer and information sciences

description: We consider robotic pick-and-place of partially visible, novel objects, where goal placements are non-trivial, e.g., tightly packed into a bin. One approach is (a) use object instance segmentation and shape completion to model the objects and (b) use a regrasp planner to decide grasps and places displacing the models to their goals. However, it is critical for the planner to account for uncertainty in the perceived models, as object geometries in unobserved areas are just guesses. We account for perceptual uncertainty by incorporating it into the regrasp planner's cost function. We compare seven different costs. One of these, which uses neural networks to estimate probability of grasp and place stability, consistently outperforms uncertainty-unaware costs and evaluates faster than Monte Carlo sampling. On a real robot, the proposed cost results in successfully packing objects tightly into a bin 7.8% more often versus the commonly used minimum-number-of-grasps cost.

Particle Ratios in Heavy-Ion Collisions

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: In framework of statistical models, different particle ratios at energies ranging from $3.5 $ to $200 $GeV are calculated. Assuming that the particle production takes place along the freeze-out curve, we study the sharp peak in $K^+/π^+$ ratio observed at SPS energy. We study the responsibility of non-equilibrium quark occupancy of phase space $γ_i$ for particle production. Allowing $γ_i$ to take values other than that of equilibrium, we got a very well description for $K^+/π^+$ ratio at all energies. Using the resulting parameter set, we analyzed the $K^-/π^-$, $Λ/π^+$ and \hbox{$Λ/$} ratios. We found that the corresponding peaks all are located at the same value of energy, $\sqrt{s_{NN}}^{(c)}\simeq7.5 $GeV. At this energy, the entropy per particle is singular. The saddle-point in entropy per particle likely refers to critical phenomenon and change in the phase space.

description: Most published studies which consider the forecasting of agricultural prices have utilised the econometric technique. In many non-agricultural forecasting situations, the Box-Jenkins technique has been found to be of equal accuracy. This paper compares the forecasting accuracy of the Box-Jenkins and econometric techniques for forecasting manufacturing-grade beef prices in the United States of America, and suggests that the Box-Jenkins technique may be the more accurate.

description: In 2019, the Galactic center black hole Sgr A* produced an unusually high number of bright near-infrared flares, including the brightest-ever detected flare (Do et al 2019, Gravity Collaboration 2020). We propose that this activity was triggered by the near simultaneous infall of material shed by G1 and G2 objects due to their interaction with the background accretion flow. We discuss mechanisms by which S-stars and G-objects shed material, and estimate both the quantity of material and the infall time to reach the black hole.

description: An alcohol (pentanol) droplet exhibits spontaneous agitation on an aqueous solution, driven by a solutal Marangoni effect. We found that the droplet's mode of motion is controlled by its volume. A droplet with a volume of less than $0.1 μ\rm{l}$ shows irregular translational motion, whereas intermediate-sized droplets of $0.1-200 μ\rm{l}$ show vectorial motion. When the volume is above $300 μ\rm{l}$, the droplet splits into smaller drops. These experimental results regarding mode selection are interpreted in terms of the wave number selection depending on the droplet volume.

Subjects: Livestock Production/Industries

description: This paper reports on the evaluation of the performance of several forecasting methods used to forecast New South Wales quarterly beef production, one quarter ahead. The forecasting procedures used are a single equation regression model, a Box-Jenkins univariate time series model, a forecasting committee's judgement and a naive model. Absolute accuracy and relative accuracy measures are used to evaluate ex ante forecasts. Although the evaluation gave some mixed results according to the criteria used, it appears that the forecasting committee performed better than the alternative forecasting procedures considered in this study. However, the results indicate that the committee's performance was not much better than that of a naive (no change) model, indicating there is room for improvement.

description: A method for the evaluation of the epsilon expansion of multi-loop massless Feynman integrals is introduced. This method is based on the Gegenbauer polynomial technique and the expansion of the Gamma function in terms of harmonic sums.

description: Solving an acoustic wave equation using a parabolic approximation is a popular approach for many existing ocean acoustic models. Commonly used parabolic equation (PE) model programs, such as the range-dependent acoustic model (RAM), are discretized by the finite difference method (FDM). Considering the idea and theory of the wide-angle rational approximation, a discrete PE model using the Chebyshev spectral method (CSM) is derived, and the code is developed. This method is currently suitable only for range-independent waveguides. Taking three ideal fluid waveguides as examples, the correctness of using the CSM discrete PE model in solving the underwater acoustic propagation problem is verified. The test results show that compared with the RAM, the method proposed in this paper can achieve higher accuracy in computational underwater acoustics and requires fewer discrete grid points. After optimization, this method is more advantageous than the FDM in terms of speed. Thus, the CSM provides high-precision reference standards for benchmark examples of the range-independent PE model.

description: It is not likely that Governments will take precipitous action following the Uruguay Round. However, the large industrial economies should continue to press heavily for the revision of farm programs until a better accommodation is reached. The moves toward gradual decoupling of farmers' support payments from agricultural output and price levels should be the first order of business of Governments everywhere. This reform should be supplemented by greater international attention to domestic policies which create non-tariff barriers to trade.

description: We investigate the critical dynamics of a classical ferromagnet on the simple cubic lattice with double-exchange interaction. Estimates for the dynamic critical exponents $z$ and $θ$ are obtained using short-time Monte Carlo simulations. We also estimate the static critical exponents $ν$ and $β$ studying the behavior of the samples at an early time. Our results are in good agreement with available estimates and support the assertion that this model and the classical Heisenberg model belong to the same universality class.

Livestock Production/Industries

description: Regulation of the New South Wales dairy industry creates inefficiencies and raises the cost of production. In this study, the industry is modelled by adapting an ABARE subregional programming model, and using spatial equilibrium linear activity analysis to examine the effects on the production of market and manufacturing milk within different regions of New South Wales of alternative policies. The output generated by the model includes regional market and manufacturing milk production levels, prices and quantities of market milk sold in each period and region, and market and manufacturing milk transfers between regions. The model also generates details of farm-level activities for each of the representative farms used in the construction of the model. Broadly speaking, the results generated by the model are consistent with economic theory and previous studies, and point to higher social welfare levels under a less regulated industry structure. However, with respect to the regional structure of the industry, some of the results generated by the model contradict earlier research. In a further series of experiments, the policy scenarios are re-examined after the model has been adjusted to correspond more closely with a long-run situation. Under these circumstances, the opportunity costs of land used in dairying heavily influences the long term structure of the industry. Differences in results between the long-run and short-run cases highlight the need for caution in interpreting the output from complex mathematical programming models.
Absence of Dipole Glass Transition for Randomly Dilute Classical Ising Dipoles

description: Dilute dipolar systems in three dimensions are expected to undergo a spin glass transition as the temperature decreases. Contrary to this, we find from Wang-Landau Monte Carlo simulations that at low concentrations $x$, dipoles randomly placed on a cubic lattice with dipolar interactions do not undergo a phase transition. We find that in the thermodynamic limit the ``glass'' transition temperature $T_g$ goes to zero as $1/\sqrt{N}$ where $N$ is the number of dipoles. The entropy per particle at low temperatures is larger for lower concentrations ($x=4.5%$) than for higher concentrations ($x=20%$).

description: Despite the availability of a spin Hamiltonian for the Gd3Ga5O12 garnet (GGG) for over twenty five years, there has so far been little theoretical insight regarding the many unusual low temperature properties of GGG. Here we investigate GGG in zero magnetic field using mean-field theory. We reproduce the spin liquid-like correlations and, most importantly, explain the positions of the sharp peaks seen in powder neutron diffraction experiments. We show that it is crucial to treat accurately the long-range nature of the magnetic dipolar interactions to allow for a determination of the small exchange energy scales involved in the selection of the experimental ordering wave vector. Our results show that the incommensurate order in GGG is classical in nature, intrinsic to the microscopic spin Hamiltonian and not caused by weak disorder.

description: The Cluster HEritage project with XMM-Newton - Mass Assembly and Thermodynamics at the Endpoint of structure formation (CHEX-MATE) is a three mega-second Multi-Year Heritage Programme to obtain X-ray observations of a minimally-biased, signal-to-noise limited sample of 118 galaxy clusters detected by Planck through the Sunyaev-Zeldovich effect. The programme, described in detail in this paper, aims to study the ultimate products of structure formation in time and mass. It is composed of a census of the most recent objects to have formed (Tier-1: 0.05 < z < 0.2; 2 x 10e14 M_sun < M_500 < 9 x 10e14 M_sun), together with a sample of the highest-mass objects in the Universe (Tier-2: z < 0.6; M_500 > 7.25 x 10e14 M_sun). The programme will yield an accurate vision of the statistical properties of the underlying population, measure how the gas properties are shaped by collapse into the dark matter halo, uncover the provenance of non-gravitational heating, and resolve the major uncertainties in mass determination that limit the use of clusters for cosmological parameter estimation. We will acquire X-ray exposures of uniform depth, designed to obtain individual mass measurements accurate to 15-20% under the hydrostatic assumption. We present the project motivations, describe the programme definition, and detail the ongoing multi-wavelength observational (lensing, SZ, radio) and theoretical effort that is being deployed in support of the project.

description: Since 1992 there have been some major debates and decisions on Australian agricultural policy issues. Recent policy issues of the dairy, wool, wheat and meat industries are canvassed, as well as current policies on rural adjustment and drought, and the latest policy direction of the National Farmers Federation are documented. Emerging emphases in policy include adding value to commodities, privatization of activities of statutory authorities, and the management of resources and risk by farmers. In agricultural policy formation in 1992-1994 these new emphases confronted the old imperatives of agriculture.

description: We report on 2MASS J01542930+0053266, a faint eclipsing system composed of two M dwarfs. The variability of this system was originally discovered during a pilot study of the 2MASS Calibration Point Source Working Database. Additional photometry from the Sloan Digital Sky Survey yields an 8-passband lightcurve, from which we derive an orbital period of 2.6390157 +/- 0.0000016 days. Spectroscopic followup confirms our photometric classification of the system, which is likely composed of M0 and M1 dwarfs. Radial velocity measurements allow us to derive the masses (M_1 = 0.66 +/- 0.03 M_sun; M_2 = 0.62 +/- 0.03 M_sun) and radii (R_1 = 0.64 +/- 0.08 R_sun; R_2 = 0.61 +/- 0.09 R_sun) of the components, which are consistent with empirical mass-radius relationships for low-mass stars in binary systems. We perform Monte Carlo simulations of the lightcurves which allow us to uncover complicated degeneracies between the system parameters. Both stars show evidence of H-alpha emission, something not common in early-type M dwarfs. This suggests that binarity may influence the magnetic activity properties of low-mass stars; activity in the binary may persist long after the dynamos in their isolated counterparts have decayed, yielding a new potential foreground of flaring activity for next generation variability surveys.

description: We report an experimental study of quantum conductivity corrections in a low mobility, high density two-dimensional electron gas in a AlGaAs/GaAs/AlGaAs quantum well in a wide temperature range (1.5K - 110K). This temperature range covers both the diffusive and the ballistic interaction regimes for our samples. It has been therefore possible to study the crossover between these regimes for both the longitudinal conductivity and the Hall effect. We perform a parameter free comparison of our experimental data for the longitudinal conductivity at zero magnetic field, the Hall coefficient, and the magnetoresistivity to the recent theories of interaction-induced corrections to the transport coefficients. A quantitative agreement between these theories and our experimental results has been found.

description: This paper is the second of a two-part survey on noncooperative game theory relevant to agricultural markets. Part 1 of the survey focused on important game theory concepts, while this paper illustrates applications of the theory to agricultural markets. Game theory is relevant when markets are imperfectly competitive, and this paper argues that this condition is commonly met in agriculture. Specific topics of application include principal-agent models, auctions, and bargaining.

The experience of self-destructive behavior in First Nations adolescent girls
Creators: name: Davis, Sarah
Publisher: name: University of British Columbia
Year: 2009

description: This study is an attempt to better understand the experience of self-destructive behaviour in First Nations adolescent girls by telling their stories, discussing factors that may contribute to the behaviours, and providing counselling insight. Not every Native girl experiences self-destructive behaviour, however those that do require more effective solutions to their problems. There is ample literature regarding non-Native girls and their experiences with self-destructive behaviour. This is not the case with Native girls, and this study is an attempt to fill the literature gap, and at the same time provide insight into counselling practice. Many factors may contribute to the experience of self-destructive behaviour in First Nations adolescent girls (e.g., gender, developmental stages, parenting, cultural norms and values, and discrimination). The combination of these issues compounds each other and creates the context for the experience of self-destructive behaviour specific to Native girls. This reality puts them at risk for truancy, juvenile delinquency, teen pregnancy, drug and alcohol abuse, depression, anxiety, eating disorders, self-harming, and ultimately suicide. In order to understand the circumstances or events that lead to a young Native woman's experience with self-destructive behaviour I interviewed three women using in-depth, semi structured interviews. When answering the open-ended questions I asked, the interviewees revealed a story with a beginning, middle, and end. This story reflected the different stages in their lives, childhood, adolescence, and eventually young adulthood. Analysis of the interviews through theme identification revealed common threads through each woman's life. Although each woman had unique experiences, their stories revealed many commonalties. These common themes reflect factors that counsellors should consider when counselling First Nations girls who are experiencing self-destructive behaviour. The results of the study suggest that counsellors should not isolate factors that lead to self-destructive behaviour. For example, First Nations girls experience not just racism or neglectful parenting — they experience both of the factors. The contributing factors begin early in life and compound one another as the girl's life progresses. Hopefully, this study contributes to the betterment of individual Native girls, also to the betterment of the families' and communities' health.
Macroscopic Superposition States in Isolated Quantum Systems

description: For any choice of initial state and weak assumptions about the Hamiltonian, large isolated quantum systems undergoing Schrodinger evolution spend most of their time in macroscopic superposition states. The result follows from von Neumann's 1929 Quantum Ergodic Theorem. As a specific example, we consider a box containing a solid ball and some gas molecules. Regardless of the initial state, the system will evolve into a quantum superposition of states with the ball in macroscopically different positions. Thus, despite their seeming fragility, macroscopic superposition states are ubiquitous consequences of quantum evolution. We discuss the connection to many worlds quantum mechanics.

description: Sources and uses of funds in agricultural cooperatives are examined and compared to the aggregate of nonfinancial corporations for the period 1973-1987. Cooperatives are observed to finance nearly half their growth with equity. The equity financing proportion of cooperatives is statistically indistinguishable from the national average of nonfinancial corporations in the years 1973-1983 and is consistently higher than the national average since 1984. This finding contradicts the hypothesis of equity shortage in cooperatives.

description: I review the development of numerical evolution codes for general relativity based upon the characteristic initial value problem. Progress is traced from the early stage of 1D feasibility studies to 2D axisymmetric codes that accurately simulate the oscillations and gravitational collapse of relativistic stars and to current 3D codes that provide pieces of a binary black spacetime. A prime application of characteristic evolution is to compute waveforms via Cauchy-characteristic matching, which is also reviewed.

description: The orbital angular momentum (OAM) of photons presents a degree of freedom for enhancing the secure key rate of free-space quantum key distribution (QKD) through mode-division multiplexing (MDM). However, atmospheric turbulence can lead to substantial modal crosstalk, which is a long-standing challenge to MDM for free-space QKD. Here, we show that the digital generation of time-reversed wavefronts for multiple probe beams is an effective method for mitigating atmospheric turbulence. We experimentally characterize seven OAM modes after propagation through a 340-m outdoor free-space link and observe an average modal crosstalk as low as 13.2% by implementing real-time time reversal. The crosstalk can be further reduced to 3.4% when adopting a mode spacing $Δ\ell$ of 2. We implement a classical MDM system as a proof-of-principle demonstration, and the bit error rate is reduced from $3.6\times 10^{-3}$ to be less than $1.3\times 10^{-7}$ through the use of time reversal. We also propose a practical and scalable scheme for high-speed, mode-multiplexed QKD through a turbulent link. The modal crosstalk can be further reduced by using faster equipment. Our method can be useful to various free-space applications that require crosstalk suppression.

Productivity Analysis

description: Accurate estimates of returns to scale require that inputs and output are measured without error and that environmental and managerial differences among firms of varying sizes are taken into account. Measurement problems affecting estimates of returns to scale in agriculture include: (1) combining the farm dwelling with capital inputs, (2) correlation of environmental and management characteristics with size and (3) the effect of off-farm employment on small farm output and production costs. Estimates of long run average total cost curves for farms in the corn belt reveal that after the above factors are taken into account, estimated scale economies in agriculture disappear, while there is evidence of diseconomies as farm size increases.

description: Nonlinear SU(1,1) interferometers are fruitful and promising tools for spectral engineering and precise measurements with phase sensitivity below the classical bound. Such interferometers have been successfully realized in bulk and fiber-based configurations. However, rapidly developing integrated technologies provide higher efficiencies, smaller footprints, and pave the way to quantum-enhanced on-chip interferometry. In this work, we theoretically realised an integrated architecture of the multimode SU(1,1) interferometer which can be applied to various integrated platforms. The presented interferometer includes a polarization converter between two photon sources and utilizes a continuous-wave (CW) pump. Based on the potassium titanyl phosphate (KTP) platform, we show that this configuration results in almost perfect destructive interference at the output and supersensitivity regions below the classical limit. In addition, we discuss the fundamental difference between single-mode and highly multimode SU(1,1) interferometers in the properties of phase sensitivity and its limits. Finally, we explore how to improve the phase sensitivity by filtering the output radiation and using different seeding states in different modes with various detection strategies.
Characteristic formulation of the Regge-Wheeler and Zerilli Green functions

description: We present a characteristic initial value approach to calculating the Green function of the Regge-Wheeler and Zerilli equations. We combine well-known numerical methods with newly derived initial data to obtain a scheme which can in principle be generalised to any desired order of convergence. We demonstrate the approach with implementations up to sixth-order in the grid spacing. By combining the results of our numerical code with late-time tail expansions and methods of subtracting the direct part of the Green function, we show that the scalar self-force in Schwarzschild spacetime can be computed to better accuracy than previous Green-function based approaches. We also demonstrate agreement with frequency-domain methods for computing the Green function in the gravitational case. Finally, we apply the Regge-Wheeler and Zerilli Green functions to the computation of the gravitational energy flux.

description: In his first 1941 paper Kolmogorov assumed that the velocity has increments which are homogeneous and independent of the velocity at a suitable reference point. This assumption of local homogeneity is consistent with the nonlinear dynamics only in an asymptotic sense when the reference point is far away. The inconsistency is illustrated numerically using the Burgers equation. Kolmogorov's derivation of the four-fifths law for the third-order structure function and its anisotropic generalization are actually valid only for homogeneous turbulence, but a local version due to Duchon and Robert still holds. A Kolomogorov--Landau approach is proposed to handle the effect of fluctuations in the large-scale velocity on small-scale statistical properties; it is is only a mild extension of the 1941 theory and does not incorporate intermittency effects.
