Subjects: subject: 80101 Adaptive Agents and Intelligent Robotics

description: Provides a geometric representation of friction for a rigid planar part with two translational and one rotational degrees of freedom. The construction of a generalized friction cone is accomplished by imbedding into the part's configuration space the constraints that define the classical friction cone in real space. The resulting representation provides a simple computational method for determining the possible motions of a part subjected to an applied force and torque. The representation has been used both for simulating part motions and for planning assembly operations. Generalizations to the six-dimensional configuration space of a three-dimensional part are possible.

description: A cross-diffusion system modeling the information herding of individuals is analyzed in a bounded domain with no-flux boundary conditions. The variables are the species' density and an influence function which modifies the information state of the individuals. The cross-diffusion term may stabilize or destabilize the system. Furthermore, it allows for a formal gradient-flow or entropy structure. Exploiting this structure, the global-in-time existence of weak solutions and the exponential decay to the constant steady state is proved in certain parameter regimes. This approach does not extend to all parameters. We investigate local bifurcations from homogeneous steady states analytically to determine whether this defines the validity boundary. This analysis shows that generically there is a gap in the parameter regime between the entropy approach validity and the first local bifurcation. Next, we use numerical continuation methods to track the bifurcating non-homogeneous steady states globally and to determine non-trivial stationary solutions related to herding behaviour. In summary, we find that the main boundaries in the parameter regime are given by the first local bifurcation point, the degeneracy of the diffusion matrix and a certain entropy decay validity condition. We study several parameter limits analytically as well as numerically, with a focus on the role of changing a linear damping parameter as well as a parameter controlling the cross-diffusion. We suggest that our paradigm of comparing bifurcation-generated obstructions to the parameter validity of global-functional methods could also be of relevance for many other models beyond the one studied here.

description: Soil salt damage has become one of the main biological stresses affecting plant seed germination, crop growth and yield. Salt damage can lead to the accumulation of superoxide anion, hydrogen peroxide and hydroxyl free radicals in plants, and a large amount of accumulated reactive oxygen species will cause the oxidation of lipids, proteins and nucleic acids and then cause cell damage. In this experiment, the seedlings and adult plants of transgenic Arabidopsis with overexpression of Zostera japonica (Z. japonica) DnaJ gene ZjDjB1 were used as materials. Wild-type and transgenic ZjDjB1 Arabidopsis were treated with 100 mM and 200 mM NaCl and root length, fresh weight, leaf water content and dry weight, physiological indexes and antioxidant system enzyme activities were measured. The results showed that overexpression of Z. japonica DnaJ gene ZjDjB1 could significantly alleviate the damage caused by salt stress to transgenic ZjDjB1 Arabidopsis seedlings and adult plants. The results showed that overexpression of Z. japonica DnaJ gene ZjDjB1 could reduce the content of MDA and O2-, increase the content of proline and activate the enzyme activity of antioxidant system under salt stress, to reduce the damage of salt stress to plants.

description: This note attempts to make it easier for non-technology experts to respond to Q3 of the National Data Strategy consultation, which is open for consultation until 2 December. The National Data Strategy is about decision making. Data drives decisions, and the Strategy sets out a range of measures and proposals for how data about people, things and systems could and should be used in the UK. The way decisions are made in a democracy is of interest to everyone. Q3 of the consultation asks: “please provide any comments about the potential impact the proposals outlined in this consultation may have on individuals with a protected characteristic under the Equality Act 2010?” People with protected characteristics are often regarded as “edge cases” in big data sets, and consequently penalised because information is missing, incomplete, or unduly reflective of other structural biases. It is also important because - without good governance - algorithmic decisions can deepen and entrench bias and social injustice. The consultation questions are currently being considered by technology experts, privacy specialists, and data scientists, but the strategy is of interest to everyone who champions the rights of marginalised communities. To answer Q3 of the consultation, it is important to understand the impact of the Strategy in aggregate, which this briefing note attempts to do. Draft recommendations are given at the beginning and end of this document as starting points for addressing the concerns raised here. If you would like to develop these recommendations further, contribute to or co-sign a co-ordinated consultation response, please email hello@careful.industries by 15 November 2020. Otherwise, please feel free to use this note as an input in your own response. Please note that this note does not consider the privacy, security or data adequacy aspects of the proposal.

description: A hallmark feature of topological physics is the presence of one-way propagating chiral modes at the system boundary. The chirality of edge modes is a consequence of the topological character of the bulk. For example, in a non-interacting quantum Hall model, edge modes manifest as mid-gap states between two topologically distinct bulk bands. The bulk-boundary correspondence dictates that the number of chiral edge modes, a topological invariant called the winding number, is completely determined by the bulk topological invariant, the Chern number. Here, for the first time, we measure the winding number in a 2D photonic system. By inserting a unit flux quantum at the edge, we show that the edge spectrum resonances shift by the winding number. This experiment provides a new approach for unambiguous measurement of topological invariants, independent of the microscopic details, and could possibly be extended to probe strongly correlated topological orders.

We build this projector and check its properties to the first two orders in the number operator and to all orders in the deformation parameter. We then find the relation between the gravitational and internal gauge couplings in the resulting unified three-dimensional Chern--Simons theory for Blencowe--Vasiliev higher spin gravity coupled to fractional spin fields and internal gauge potentials. We also examine the model for integer or half-integer fractional spins, where infinite dimensional ideals arise and decouple, leaving finite dimensional gauge algebras $gl(2l+1)$ or $gl(l|l+1)$ and various real forms thereof.

description: We devise and experimentally realize a procedure capable of detecting and distinguishing quantum discord and classical correlations as well the presence of factorized states in a joint system-environment setting. Our scheme builds on recent theoretical results showing how the distinguishability between two reduced states of a quantum system in a bipartite setting can convey important information about the correlations present in the bipartite state and the interaction between the subsystems. The two addressed subsystems are the polarization and spatial degrees of freedom of the signal beam generated by parametric down-conversion, which are suitably prepared by the idler beam. Different global and local operations allow for the detection of different correlations by studying via state tomography the trace distance behavior between suitable polarization subsystem states.

description: The finite-temperature magnetism of a monolayer on a bcc (110) surface was examined using a model Hamiltonian containing ferromagnetic or antiferromagnetic exchange interactions, Dzyaloshinsky-Moriya interactions and easy-axis on-site anisotropy. We examined the competition between the collinear ground state parallel to the easy axis and the spin spiral state in the plane perpendicular to this axis preferred by the Dzyaloshinsky-Moriya interaction. Using approximative methods to calculate the magnon spectrum at finite temperatures, it was found that even if the ground state is collinear, increasing the Dzyaloshinsky-Moriya interaction strongly decreases the critical temperature where this collinear order disappears. Using atomistic spin dynamics simulations it was found that at this critical temperature the system transforms into the non-collinear state. Including external magnetic field helps stabilising the ferromagnetic state. An effect due to the finite size of the magnetic monolayer was included in the model by considering a different value for the anisotropy at the edges of the monolayer. This effect was shown to stabilize the spin spiral state by fixing the phase at the ends of the stripe.

Accurate and Flexible Simulation for Dynamic, Vision-Centric Robots

description: As robots become more complex by incorporating dynamic stability or greater mechanical degrees of freedom, the
difficulty of developing control algorithms directly on the robot increases. This is especially true for large or expensive
robots, where damage is costly, or where communication bandwidth limits in-depth debugging. One effective solution to
this problem is the use of a flexible, physically-accurate simulation environment which allows for experimentation with
the physical composition and control systems of one or more robots in a controlled virtual setting. While many robot
simulation environments are available today, we find that achieving accurate simulation of complex, vision-centric
platforms such as the Segway RMP or Sony AIBO requires accurate modeling of latency and robust synchronization.
Building on our previous work, we present an open-source simulation framework, ÜberSim, and demonstrate its ability to
simulate vision-centric, balancing robots in a realistic fashion. The focus of this simulation environment is on accurate
simulation with high-frequency control loops and flexible configuration of robot structure and parameters via a client-side
definition language.

description: This study explores the representation of interpreters in the Turkish news media by analysing the online editions of the three most circulated Turkish newspapers between June 2017 and March 2021. It looks at what triggers a media discourse on interpreters and how interpreters are represented in the news media. It also juxtaposes the current portrayal of conference and diplomatic interpreters with the media coverage of conference interpreters in two previous studies. The results indicate that although references to interpreters working in legal settings are by far the most numerous, these references are almost always in passing, giving interpreters in these settings no visibility or voice. The same applies to interpreters working in refugee settings. In contrast, news items on sign language and football interpreters accord significant visibility and voice to these interpreters. News reports on conference and diplomatic interpreters, on the other hand, seem to reflect a marked shift towards negative coverage, characterised by the absence of interpreters’ voices and a media discourse that contests their neutrality, the latter view of interpreters being at least partly related to political tensions in the country.

description: The successful introduction of electric vehicles continues to be stiﬂed by the high cost and limited perfor-mance life of battery technology. We assert that a disruptive improvement in systems-level cost-of-performance is possible by employing a rate-heterogeneous energy storage system, combining low-rate batteries and high-rate supercapacitors, that is mated to a predictive control system that optimizes power management by exploiting topographic information, traffic history, and specific driver performance. Such predictive power management, optimizing energy storage throughout episodes of vehicle acceleration and regenerative braking, has the potential to significantly decrease the total energy duty on the vehicle’s batteries.

description: We address the task of inferring the future actions of people from noisy visual input. We denote this task activity forecasting. To achieve accurate activity forecasting, our approach models the effect of the physical environment on the choice of human actions. This is accomplished by the use of state-of-the-art semantic scene understanding combined with ideas from optimal control theory. Our unified model also integrates several other key elements of activity analysis, namely, destination forecasting, sequence smoothing and transfer learning. As proof-of-concept, we focus on the domain of trajectory-based activity analysis from visual input. Experimental results demonstrate that our model accurately predicts distributions over future actions of individuals.We show how the same techniques can improve the results of tracking algorithms by leveraging information about likely goals and trajectories.

description: Neural networks along the spinal cord contribute substantially to generating locomotion behaviours in humans and other legged animals. However, the neural circuitry involved in this spinal control remains unclear. We here propose a specific circuitry that emphasizes feedback integration over central pattern generation. The circuitry is based on neurophysiologically plausible muscle-reflex pathways that are organized in 10 spinal modules realizing limb functions essential to legged systems in stance and swing. These modules are combined with a supraspinal control layer that adjusts the desired foot placements and selects the leg that is to transition into swing control during double support. Using physics-based simulation, we test the proposed circuitry in a neuromuscular human model that includes neural transmission delays, musculotendon dynamics and compliant foot-ground contacts. We find that the control network is sufficient to compose steady and transitional 3-D locomotion behaviours including walking and running, acceleration and deceleration, slope and stair negotiation, turning, and deliberate obstacle avoidance. The results suggest feedback integration to be functionally more important than central pattern generation in human locomotion across behaviours. In addition, the proposed control architecture may serve as a guide in the search for the neurophysiological origin and circuitry of spinal control in humans.

description: This paper describes state-of-the-art digital filtering techniques that are part of GEANA, an automatic data analysis software used for the GERDA experiment. The discussed filters include a novel, nonlinear correction method for ballistic deficits, which is combined with one of three shaping filters: a pseudo-Gaussian, a modified trapezoidal, or a modified cusp filter. The performance of the filters is demonstrated with a 762 g Broad Energy Germanium (BEGe) detector, produced by Canberra, that measures γ-ray lines from radioactive sources in an energy range between 59.5 and 2614.5 keV. At 1332.5 keV, together with the ballistic deficit correction method, all filters produce a comparable energy resolution of ~1.61 keV FWHM. This value is superior to those measured by the manufacturer and those found in publications with detectors of a similar design and mass. At 59.5 keV, the modified cusp filter without a ballistic deficit correction produced the best result, with an energy resolution of 0.46 keV. It is observed that the loss in resolution by using a constant shaping time over the entire energy range is small when using the ballistic deficit correction method.

description: Triple photoionization of Xe3+, Xe4+ and Xe5+ ions has been studied in the energy range 670-750 eV, including the 3d ionization threshold. The photon-ion merged-beam technique was used at a synchrotron light source to measure the absolute photoionization cross sections. These cross sections exhibit a progressively larger number of sharp resonances as the ion charge state is increased. This clearly visualizes the re-ordering of the $ε$f continuum into a regular series of (bound) Rydberg orbitals as the ionic core becomes more attractive. The energies and strengths of the resonances are extracted from the experimental data and are further analyzed by relativistic atomic-structure calculations.

A Numberless, Tensed Language for Action Oriented Tasks

Publisher: name: Figshare

Subjects: subject: 80101 Adaptive Agents and Intelligent Robotics
subject: FOS: Computer and information sciences

description: Action oriented languages arc number intensive. Graphic languages arc centered around where to draw
something rather than what to draw. The "where" involves a tedious numeric description of vertices.Robotics languages are also dominated by a "where" description. but now the "where" specifics a robot motion. The result is an array of numbers that obscures the meaning of the program to its reader.

This paper shows how a number of linguistic devices can be used to eradicate the plethora of numbers from action oriented descriptions. Functions or verbs can be tensed (c.g., past tense) to modify their meaning without duplicating the root function. 'I'he result is an English-like description of a control structure.
Arguments or nouns can be modified in name, like the use of a GENSYM function in Lisp which generates a
unique variable name from a character string. and in number (e.g., singular vs. plural). The result is an English-like description of bound and quantified variables. The remaining quantitative description of action tasks can be relegated to a database whose management system is specialized for number management.

'The resulting language is a formal variant of a natural language with a Lisp-like syntax (i.e., lists with functions in the first position). The programs approach the readability of a natural language without the cost
of ambiguity that is inherent in natural descriptions. Finally. the programs can be easily pretty printed in
English so that they can bc read by non-programmers.

The application of the response function for crystalline helium has enabled determination of the contributions from the collective degrees of freedom to the shift and broadening. It occurs that the broadening due to the collective motion is negligible compared to the natural line width. The available pair-correlation functions for crystalline $^4$He have been applied for estimating the resonance-line shift due to collisions of $\bar{p}\mathrm{He}^{+}$ atom with the surrounding $^4$He atoms. The dependence of the line shift, which has been calculated in the quasistatic limit, on the solid-$^4$He density is nonlinear.

Because traditional spacecraft consume considerable amounts of fuel and are expensive, there has been an increase in interest in solar sails, which is an affordable and easier way to navigate through space, using only the momentum of photons from the Sun. This study aims to further develop the mission designed to reach Mars with a solar sail powered CubeSat spacecraft. To make the mission as realistic as possible, detailed orbital analyses of several Mars orbiter missions are performed and the trajectories are implemented into the script, also including the orbits of the moons of Mars, Phobos and Deimos. Additionally, the orbital design and analysis necessary to make it possible to fly by Mars and the Martian moons are performed. The analyses carried out in this study highlighted the advantages of solar sailing, showing the possibility of an interplanetary mission without chemical engines. A more accurate model of solar radiation pressure is implemented with the use of an SPAD file, allowing us to observe the differences among various SRP models. The cannonball model is implemented in this study for a more realistic approach to solar radiation pressure. Furthermore, several FOSS software, such as GMAT, Horizons and Mathematica are used for analyses, plotting and simulations, which are discussed in detail. This study aims to act as a guide for future interplanetary solar sail powered missions.

description: We present a simultaneous extraction of the moments of $F_2$ and $F_L$ structure functions of the proton at a range of photon virtuality, $Q^2$. This is achieved by computing the forward Compton amplitude via an application of the second-order Feynman-Hellmann method. We find the moments of $F_{2,L}$ in good agreement with experimental values. By studying the $Q^2$ dependence of $F_2$ moments, we estimate the power corrections.

description: A new formulation for obtaining the tunneling action for vacuum decay based on the so-called tunneling potential was developed recently. In the original derivation, the new action was obtained by requiring that its variation led to the correct equations of motion and the same value for the action as evaluated on the Euclidean bounce. We present an alternative derivation of the tunneling potential action via canonical transformations. We discuss both single-field and multi-field cases as well as the case with gravity. We also comment on the possible application of the new approach to the calculation of the functional determinant prefactor in the tunneling rate.

description: The semiconscious choice of unhealthy foods is investigated to provide a transferable branding-like method to quantify obesogenity in terms of consumers’ propensities to habituation. Some triggers of unhealthy food consumption and all the food choices associated to such cues were found as statistically independent from consumers’ motivations, particularly for two-thirds of consumers.

description: The coagulation of microscopic dust into planetesimals is the first step towards planet formation. The size and shape of the growing aggregates determine the efficiency of this early growth. It has been proposed that fluffy ice aggregates can grow very efficiently, suffering less from the bouncing and radial drift barriers. While the collision velocity between icy aggregates of similar size is thought to stay below the fragmentation threshold, they may nonetheless lose mass from collisions with much smaller projectiles. We investigate the effect of these erosive collisions on the ability of porous ice aggregates to cross the radial drift barrier. We develop a Monte Carlo code that calculates the evolution of the growing aggregates, while resolving the entire mass distribution at all times. The aggregate's porosity is treated independently of its mass, and is determined by collisions, gas compaction, and eventually self-gravity compaction. For erosion threshold velocities of 20-40 m/s, high-velocity collisions with small projectiles prevent the largest aggregates from growing when they start to drift. In these cases, our local simulations result in a steady-state distribution, with the majority of the dust mass in particles with Stokes numbers close to unity. Only for the highest erosion threshold considered (60 m/s), do porous aggregates manage to cross the radial drift barrier in the inner 10 AU of MMSN-like disks. Erosive collisions are more effective in limiting the growth than fragmentary collisions between similar-size particles. Conceivably, erosion limits the growth before the radial drift barrier, although the robustness of this statement depends on (uncertain) material properties of icy aggregates. If erosion inhibits planetesimal formation through direct sticking, the sea of ${\sim}10^9$ g, highly porous particles appears well-suited for triggering streaming instability.

description: First-order cosmological phase transitions in the early Universe source sound waves and, subsequently, a background of stochastic gravitational waves. Currently, predictions of these gravitational waves rely heavily on simulations of a Higgs field coupled to the plasma of the early Universe, the former providing the latent heat of the phase transition. Numerically, this is a rather demanding task since several length scales enter the dynamics. From smallest to largest, these are the thickness of the Higgs interface separating the different phases, the shell thickness of the sound waves, and the average bubble size. In this work, we present an approach to perform Higgsless simulations in three dimensions, producing fully nonlinear results, while at the same time removing the hierarchically smallest scale from the lattice. This significantly reduces the complexity of the problem and contributes to making our approach highly efficient. We provide spectra for the produced gravitational waves for various choices of wall velocity and strength of the phase transition, as well as introduce a fitting function for the spectral shape.

description: We report a combined experimental and theoretical simulation of multiply scattered light dynamics in an ultracold gas of 85Rb atoms. Measurements of the spectral dependence of the time-decay of the scattered light intensity, following pulsed excitation with near resonance radiation, reveals that the decay for long times is nearly exponential, with a decay constant that is largely independent of detuning from resonance. Monte Carlo simulations of the multiple scattering process show that, for large detunings, near resonance scattering of Fourier components of the excitation pulse plays a significant role in the effect. This interpretation is supported by the observations, and successful modelling, of beating between Rayleigh scattered light at the excitation carrier frequency with the Fourier components of the excitation pulse that overlap significantly with the atomic resonance.

description: Orienting parts that measure only a few micrometers in diameter introduces several challenges that need not be
considered at the macro-scale. First, there are several kinds of sticking effects due to Van der Waals forces and
static electricity which complicate hand-off motions and release of a part. Second, the degrees of freedom of
micro-manipulators are limited. This paper proposes a pair of manipulation primitives and a complete algorithm
that addresses these challenges. We will show that a sequence of these two manipulation primitives can uniquely
orient any asymmetric part while maintaining contact without sensing. This allows us to apply the same plan to
many (identical) parts simultaneously. For asymmetric parts we can ﬁnd a plan of length O (n) in O (n ) time that
orients the part, where n is the number of vertices.
A One-Dimensional Model for Rayleigh-Taylor Instability in Supernova Remnants

Year: 2015
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: This study presents a method for approximating the multidimensional effects of Rayleigh-Taylor instability as a modification of the one-dimensional hydro equations. This modification is similar to the Shakura-Sunyaev α prescription for modeling the coarse-grained effects of turbulence in astrophysical disks. The model introduces several dimensionless tunable parameters that are calibrated by comparing with high-resolution two-dimensional axisymmetric numerical calculations of Rayleigh-Taylor unstable flows. A complete description of the model is presented, along with a handful of test problems that demonstrate the extent to which the one-dimensional model is able to reproduce multidimensional effects.

description: Accomplishing simultaneous localization and mapping (SLAM) in very large city environments is a great challenge because of theoretical and practical  issues on computational complexity, dynamic environment, representation
and data association. In this paper, we describe practical algorithms for dealing with the representation issues. Feature based, grid-based and direct methods are integrated into the framework of the hierarchical object based representation.
The sampling and correlation based range image matching algorithm is developed to tackle the problem arising from uncertain, sparse and featureless data in outdoor environments. Experimental results of a 800 meter x 600 meter neighborhood demonstrate the feasibility of city-sized SLAM.
