description: The Multi-Object Navigation (MultiON) task requires a robot to localize an instance (each) of multiple object classes. It is a fundamental task for an assistive robot in a home or a factory. Existing methods for MultiON have viewed this as a direct extension of Object Navigation (ON), the task of localising an instance of one object class, and are pre-sequenced, i.e., the sequence in which the object classes are to be explored is provided in advance. This is a strong limitation in practical applications characterized by dynamic changes. This paper describes a deep reinforcement learning framework for sequence-agnostic MultiON based on an actor-critic architecture and a suitable reward specification. Our framework leverages past experiences and seeks to reward progress toward individual as well as multiple target object classes. We use photo-realistic scenes from the Gibson benchmark dataset in the AI Habitat 3D simulation environment to experimentally show that our method performs better than a pre-sequenced approach and a state of the art ON method extended to MultiON.

description: We study finite groups $G$ with elements $g$ such that $\lvert \mathbf{C}_G(g)\rvert = \lvert G:G' \rvert$. (Such elements generalize fixed-point-free automorphisms of finite groups.) We show that these groups have a unique conjugacy class of nilpotent supplements for the commutator subgroup and, using the classification of finite simple groups, that these groups are solvable.

description: Mobile Spielanimation ist in der Schweiz eine bewährte Methode der Soziokulturellen Animation. Sie bietet Kindern einen offenen Rahmen, in dem sie spielerisch tätig sein und sich in ihren persönlichen und sozialen Fähigkeiten weiterentwickeln können. Bekunden Kinder Mühe, sich in die Gruppe zu integrieren, sind die Fachpersonen gefordert. Die Möglichkeiten der individuellen Förderung der Kinder erscheinen in der Spielanimation begrenzt. Diesen Grenzen wird in dieser Arbeit nachgegangen, und es wird geprüft, ob und wie die individuelle Förderung der Kinder in ihren zentralen Entwicklungsaufgaben verstärkt werden könnte. Geprüft wird zudem, ob sozialpädagogische Ansätze der Schulsozialarbeit zur individuellen Förderung oder Formen der Zusammenarbeit mit der Schulsozialarbeit in Frage kommen. Mit fünf Fachpersonen der Spielanimation diverser Aktionsorte, zwei Schulsozialarbeiter*innen und einem Spielexperten wurden Expert*innen-Interviews geführt. Anschliessend wurden die Ergebnisse in der Gruppe diskutiert. Verbesserungspotential ist erkennbar beim Spiel als Methode und mit gezieltem Einbezug sozialpädagogischer Ansätze, die für das offene Setting adaptiert werden müssten, z.B. Sozialkompetenztrainings. Eine starke Kooperation mit der Schulsozialarbeit ermöglicht die Triage in Einzelfällen und gemeinsame präventive Projekte. Zudem muss auf politischer Ebene von den Organisationen und den Fachkräften der Sozialen Arbeit andauernd auf die Wirkung der Spielanimation bei den Kindern hingewiesen werden.

description: Safety and security are the two most important properties of industrial control systems (ICS), and their integration is necessary to ensure that safety goals do not undermine security goals and vice versa. Sometimes, safety and security co-engineering leads to conflicting requirements or violations capable of impacting the normal behavior of the system. Identification, analysis, and resolution of conflicts arising from safety and security co-engineering is a major challenge, an under-researched area in safety-critical systems(ICS). This paper presents an STPA-SafeSec-CDCL approach that addresses the challenge. Our proposed methodology combines the STPA-SafeSec approach for safety and security analysis and the Conflict-Driven Clause Learning (CDCL) approach for the identification, analysis, and resolution of conflicts where conflicting constraints are encoded in satisfiability (SAT) problems. We apply our framework to the Tennessee Eastman Plant process model, a chemical process model developed specifically for the study of industrial control processes, to demonstrate how to use the proposed method. Our methodology goes beyond the requirement analysis phase and can be applied to the early stages of system design and development to increase system reliability, robustness, and resilience.

description: We construct composite CFT operators from a large number of fermionic primary fields corresponding to states that are holographically dual to a zero temperature Fermi gas in AdS space. We identify a large N regime in which the fermions behave as free particles. In the hydrodynamic limit the Fermi gas forms a degenerate star with a radius determined by the Fermi level, and a mass and angular momentum that exactly matches the boundary calculations. Next we consider an interacting regime, and calculate the effect of the gravitational back-reaction on the radius and the mass of the star using the Tolman-Oppenheimer-Volkoff equations. Ignoring other interactions, we determine the "Chandrasekhar limit" beyond which the degenerate star (presumably) undergoes gravitational collapse towards a black hole. This is interpreted on the boundary as a high density phase transition from a cold baryonic phase to a hot deconfined phase.

Processes governing carbon dioxide exchange between the atmosphere and hydromagnesite-magnesite playas in Atlin, British Columbia
Creators: name: Doucet, Anne-Martine
Publisher: name: University of British Columbia
Year: 2022

description: The hydromagnesite-magnesite playas in Atlin, BC provide a unique opportunity for studying the carbonate-bicarbonate system and carbonate mineral stability at the Earth’s surface. Based on analysis of pore water samples and mineralogical data, Power et al. (2014) concluded that the playas degas CO₂ from Mg-HCO₃-rich groundwater and in-situ carbonate mineral precipitation, but CO₂ emissions were not quantified directly. In this thesis, eddy covariance (EC) and dynamic closed chamber (DCC) systems were co-located to directly quantify rates and characterize processes governing the CO₂ flux across the playa-atmosphere interface. Data were collected continuously over 27 days in 2020 and 14 days in 2021. The results from the DCC method show distinct diurnal oscillations of CO₂ fluxes, with average daytime fluxes of +0.15±0.34 μmol mˉ² sˉ¹ (2020) and +0.15±0.19 μmol mˉ² sˉ¹ (2021) and nighttime fluxes of -0.24±0.31 μmol mˉ² sˉ¹ (2020) and +0.04±0.18 μmol mˉ² sˉ¹ (2021) (positive upward and negative downward). Fluxes measured via the DCC method indicate minimal net exchange of carbon across the playa-atmosphere interface during the monitoring period. These observations imply that DCC-measured CO₂ fluxes are governed predominantly by changes in CO₂ solubility in alkaline porewater related to diurnal temperature fluctuations and variations in CO₂ concentrations in ambient air above the ground surface. However, EC measurements show a continuous positive flux averaging +1.38±0.62 μmol mˉ² sˉ¹ (2020) and +1.07±0.43 μmol mˉ² sˉ¹ (2021). The net CO₂ flux measured by EC was attributed to a source undetected by the DCCs with possible contributions from soil respiration at the playa margins or surrounding forests, or directly released via preferential pathways from a deeper source within the playa. The use of two complementary flux measurement methods revealed that CO₂ fluxes vary as a function of scale and location at this site. These findings provide insights on CO₂ flux dynamics in sparsely vegetated arid and semi-arid regions and the application of these methods for monitoring and verification of ex-situ carbon mineralization at sites with enhanced mineral weathering. The complex interactions between minerals, fluids and the atmosphere make Atlin an ideal site to test complementary methods for measuring CO₂ fluxes.

description: Diffusion in coulomb crystals can be important for the structure of neutron star crusts. We determine diffusion constants $D$ from molecular dynamics simulations. We find that $D$ for coulomb crystals with relatively soft-core $1/r$ interactions may be larger than $D$ for Lennard-Jones or other solids with harder-core interactions. Diffusion, for simulations of nearly perfect body-centered-cubic lattices, involves the exchange of ions in ring-like configurations. Here ions "hop" in unison without the formation of long lived vacancies. Diffusion, for imperfect crystals, involves the motion of defects. Finally, we find that diffusion, for an amorphous system rapidly quenched from coulomb parameter $Γ=175$ to coulomb parameters up to $Γ=1750$, is fast enough so that the system starts to crystallize during long simulation runs. These results strongly suggest that coulomb solids in cold white dwarf stars, and the crust of neutron stars, will be crystalline and not amorphous.

description: In synchrotron Moessbauer spectroscopy, the nuclear exciton polariton manifests itself in the lineshape of the spectra of nuclear forward scattering (NFS) Fourier-transformed from time domain to frequency domain. This lineshape is generally described by the convolution of two intensity factors. One of them is Lorentzian related to free decay. We derived the expressions for the second factor related to Frenkel exciton polariton effects at propagation of synchrotron radiation in Moessbauer media. Parameters of this Frenkelian shape depend on the spatial configuration of Moessbauer media. In a layer of uniform thickness, this factor is found to be a simple hypergeometric function. Next, we consider the particles spread over a 2D surface or diluted in non-Moessbauer media to exclude an overlap of ray shadows by different particles. Deconvolving the purely polaritonic component of linewidths is suggested as a simple procedure sharpening the experimental NFS spectra in frequency domain. The lineshapes in these sharpened spectra are theoretically expressed via the parameters of the particle size distributions (PSD). Then, these parameters are determined through least-squares fitting of the line shapes.

description: Excerpts from the report Explanation: This bulletin provides a summary of several statistical series, relating to farm-to-retail price spreads and marketing charges for farm products which have been developed in the Bureau of Agricultural Economics and published since 1935. The latest basic publication for foods, containing monthly data beginning January 1913, was Price Spreads Between Farmers and Consumers for Food Products, 1913-44, Miscellaneous Publication 576, which has been out of print since 1947. A statistical supplement (processed) which was released in June 1947 carried monthly data for the period January 1944 through March 1947. Current monthly estimates are released in "The Marketing and Transportation Situation, issued by the Bureau. To the data for foods there are added here two series of farm-retail price spreads for nonfood farm products: Cotton products and tobacco products. The data for cotton products begin with 1927 on an annual basis for a group of 42 cotton articles and show quarterly estimates for the 3 years 1946-48. Annual series are provided for each of three selected individual cotton articles. Price spreads for a group of four principal tobacco products are calendar-year annual averages; they begin with 1926.

description: We study high energy photodisintegration of the deuteron into two $Δ$-isobars at large center of mass angles within the QCD hard rescattering model (HRM). According to the HRM, the process develops in three main steps: the photon knocks the quark from one of the nucleons in the deuteron; the struck quark rescatters off a quark from the other nucleon sharing the high energy of the photon; then the energetic quarks recombine into two outgoing baryons which have large transverse momenta. Within the HRM, the cross section is expressed through the amplitude of $pn\rightarrow ΔΔ$ scattering which we evaluated based on the quark-interchange model of hard hadronic scattering. Calculations show that the angular distribution and the strength of the photodisintegration is mainly determined by the properties of the $pn\rightarrow ΔΔ$ scattering. We predict that the cross section of the deuteron breakup to $ Δ^{++}Δ^{-}$ is 4-5 times larger than that of the breakup to the $ Δ^{+}Δ^{0}$ channel. Also, the angular distributions for these two channels are markedly different. These can be compared with the predictions based on the assumption that two hard $Δ$-isobars are the result of the disintegration of the preexisting $ΔΔ$ components of the deuteron wave function. In this case, one expects the angular distributions and cross sections of the breakup in both $ Δ^{++}Δ^{-}$ and $ Δ^{+}Δ^{0}$ channels to be similar.

description: Radiation from a narrow circular ring shows a characteristic double-horn profile dominated by photons having energy around the maximum or minimum of the allowed range, i.e. near the extremal values of the energy shift. The energy span of a spectral line is a function of the ring radius, black hole spin, and observer's view angle. We describe a useful approach to calculate the extremal energy shifts in the regime of strong gravity. Then we consider an accretion disk consisting of a number of separate nested annuli in the equatorial plane of Kerr black hole, above the innermost stable circular orbit (ISCO). We suggest that the radial structure of the disk emission could be reconstructed using the extremal energy shifts of the individual rings deduced from the broad wings of a relativistic spectral line.

description: A study of the energy deposition in the Neutrino Factory baseline target station is presented. FLUKA simulations are used to study how much of the 4 MW proton beam power is distributed within the target station, and these results are compared with MARS simulations. About 10% of the beam power is deposited in the mercury jet target, with more than 2 MW absorbed by the tungsten- carbide shielding. Heating in the superconducting coils, that generate most of the magnetic field in the target region, can be substantially reduced by increasing the surrounding shielding. Estimates of radiation damage are also given for different sections of the target geometry.

description: This work is based on the study and calculation of a two-layer magnet in a quasi-force-free system. In particular, a system with a reduced mechanical stress-to-magnetic field ratio will be built. Several variations of the construction of such a magnet in a 2d system are considered. Data are presented showing how a change in geometry can affect the weakening of the magnetic field in the system under study. The following programs were used: Comsol multyphisics, Auto CAD. Using the Comsol multyphisics program, a quasi-force-free magnet was simulated, and the mechanical stresses arising in the corresponding magnetic field were calculated. Ultimately, methods will be provided to deal with the high mechanical stress that leads to the destruction of the magnet.

description: Neutron stars are composed of the densest form of matter known to exist in our universe, and thus provide a unique laboratory for exploring the properties of cold matter at super-nuclear density. Measurements of the masses or radii of these objects can strongly constrain the neutron-star matter equation of state, and consequently the interior composition of neutron stars. Neutron stars that are visible as millisecond radio pulsars are especially useful in this respect, as timing observations of the radio pulses provide an extremely precise probe of both the pulsar's motion and the surrounding space-time metric. In particular, for a pulsar in a binary system, detection of the general relativistic Shapiro delay allows us to infer the masses of both the neutron star and its binary companion to high precision. Here we present radio timing observations of the binary millisecond pulsar PSR J1614-2230, which show a strong Shapiro delay signature. The implied pulsar mass of 1.97 +/- 0.04 M_sun is by far the highest yet measured with such certainty, and effectively rules out the presence of hyperons, bosons, or free quarks at densities comparable to the nuclear saturation density.

description: We propose an asymptotically non-free, natural model for dynamical electro-weak symmetry breaking characterized by the emergence of a weakly coupled Higgs in the IR regime. Due to the large anomalous dimension of the Higgs operator, the model is capable of solving the hierarchy problem without losing the phenomenologically appealing features typical of a weakly coupled sector. We speculate on the possibility that such a scenario be realized as a strongly coupled phase of non-supersymmetric non-abelian gauge theories.

Application of acoustic measurements in fine coal processing

Publisher: name: University of British Columbia

description: Metallurgical coal production is crucial for the world economy. It is the main ingredient in the steelmaking process, while steel is used in construction, infrastructure, transportation, new green renewable technologies, and everyday home appliances. Flotation has been commonly used to treat very fine ore and coal; however, flotation is a complex process requiring modern automation devices to be installed to maximize its efficiency. These sophisticated systems are usually cost intensive in terms of purchase and maintenance and require someone with qualified expertise to operate them. As a result, it is difficult for some companies to implement high-tech technology, so they must rely on manual sampling—resulting in costly decision-making delays. As a result, the main focus of this research was to find a suitable method to monitor the coal flotation process using acoustic monitoring as an alternative to other conventional approaches. The acoustic monitoring method was previously tested on ore and showed reasonable efficiency in monitoring froth in the flotation using coalescence phenomena as a process indicator. For the previous research, custom-made and industrial types of hydrophones were used in the experimental work, and their ability to monitor froth was confirmed in full-scale processing plants. For this research, it was decided to carry out a fundamental analysis to determine whether the sound signal could be directly correlated with solids content in the slurry and provide information on froth loading as an indicator of flotation efficiency. The commercially available acoustic equipment was acquired for the research; it met all the requirements from an efficiency point of view and had the flexibility to be used at the processing plant. This setup was shown to be fairly robust at the laboratory scale, and it had a reasonable response to changes in solids content in the tested coal samples. As a result, it was found that this type of monitoring approach could be used, and it will perform well since it does not require a high degree of qualifications or sophisticated skills to operate. In addition, the setup has the potential to be integrated into an automation system at an operating processing plant.

description: The modified versions of the bag model equation of state (EoS) are considered. They are constructed to satisfy the main qualitative features observed for the quark-gluon plasma EoS in the lattice QCD calculations. A quantitative comparison with the lattice results at high temperatures T are done in the SU(3) gluodynamics and in the full QCD with dynamical quarks. Our analysis advocates a negative value of the bag constant B.

Long-term Stable Equilibria for Synchronous Binary Asteroids

description: Synchronous binary asteroids may exist in a long-term stable equilibrium, where the opposing torques from mutual body tides and the binary YORP (BYORP) effect cancel. Interior of this equilibrium, mutual body tides are stronger than the BYORP effect and the mutual orbit semi-major axis expands to the equilibrium; outside of the equilibrium, the BYORP effect dominates the evolution and the system semi-major axis will contract to the equilibrium. If the observed population of small (0.1 - 10 km diameter) synchronous binaries are in static configurations that are no longer evolving, then this would be confirmed by a null result in the observational tests for the BYORP effect. The confirmed existence of this equilibrium combined with a shape model of the secondary of the system enables the direct study of asteroid geophysics through the tidal theory. The observed synchronous asteroid population cannot exist in this equilibrium if described by the canonical "monolithic" geophysical model. The "rubble pile" geophysical model proposed by \citet{Goldreich2009} is sufficient, however it predicts a tidal Love number directly proportional to the radius of the asteroid, while the best fit to the data predicts a tidal Love number inversely proportional to the radius. This deviation from the canonical and \citet{Goldreich2009} models motivates future study of asteroid geophysics. Ongoing BYORP detection campaigns will determine whether these systems are in an equilibrium, and future determination of secondary shapes will allow direct determination of asteroid geophysical parameters.

description: There are no planets intermediate in size between Earth and Neptune in our Solar System, yet these objects are found around a substantial fraction of other stars. Population statistics show that close-in planets in this size range bifurcate into two classes based on their radii. It is hypothesized that the group with larger radii (referred to as "sub-Neptunes") is distinguished by having hydrogen-dominated atmospheres that are a few percent of the total mass of the planets. GJ 1214b is an archetype sub-Neptune that has been observed extensively using transmission spectroscopy to test this hypothesis. However, the measured spectra are featureless, and thus inconclusive, due to the presence of high-altitude aerosols in the planet's atmosphere. Here we report a spectroscopic thermal phase curve of GJ 1214b obtained with JWST in the mid-infrared. The dayside and nightside spectra (average brightness temperatures of 553 $\pm$ 9 and 437 $\pm$ 19 K, respectively) each show >3$σ$ evidence of absorption features, with H$_2$O as the most likely cause in both. The measured global thermal emission implies that GJ 1214b's Bond albedo is 0.51 $\pm$ 0.06. Comparison between the spectroscopic phase curve data and three-dimensional models of GJ 1214b reveal a planet with a high metallicity atmosphere blanketed by a thick and highly reflective layer of clouds or haze.

description: Trends and developments in online ethnography, By Eleonora Landucci (ESR 4) Among the methods that contribute to make anthropology a multidisciplinary field of research, online ethnography is receiving increasing attention due to the unique condition that many ethnographers are now encountering. In fact, while the use of online research methods applied to ethnography has been explored since the 1990s, after 2020 the debate is growing exponentially. The Coronavirus pandemic has further undermined the idea of an in-depth, long- lasting and far-flung research field that was already questioned by many anthropologists far before the spread of COVID-19 (Faubion and Marcus, 2009; Amit, 2000; Gupta and Ferguson, 1997). In return, the interest in qualitative research methods that involve digital technologies or actually focused on ethnographying the digital sphere has drastically grown.

description: Automated multi-label chest X-rays (CXR) image classification has achieved substantial progress in clinical diagnosis via utilizing sophisticated deep learning approaches. However, most deep models have high computational demands, which makes them less feasible for compact devices with low computational requirements. To overcome this problem, we propose a knowledge distillation (KD) strategy to create the compact deep learning model for the real-time multi-label CXR image classification. We study different alternatives of CNNs and Transforms as the teacher to distill the knowledge to a smaller student. Then, we employed explainable artificial intelligence (XAI) to provide the visual explanation for the model decision improved by the KD. Our results on three benchmark CXR datasets show that our KD strategy provides the improved performance on the compact student model, thus being the feasible choice for many limited hardware platforms. For instance, when using DenseNet161 as the teacher network, EEEA-Net-C2 achieved an AUC of 83.7%, 87.1%, and 88.7% on the ChestX-ray14, CheXpert, and PadChest datasets, respectively, with fewer parameters of 4.7 million and computational cost of 0.3 billion FLOPS.

description: The PLATO mission (PLAnetary Transits and Oscillations of stars, hereafter abbreviated as PLATO) has been selected as part of ESA’s Cosmic Vision 2015–2025 program for the M3 mission launch foreseen in 2026. The main science goal of PLATO is to detect and characterize extrasolar planets, including terrestrial planets in the habitable zone (HZ) of their host stars. Characterization here means to derive accurate planetary radii, masses, and ages. In order to achieve these goals, it is mandatory to characterize the host stars. As transit search is an indirect detection and characterization method, the accurate knowledge of the host star parameters limits the accuracy of the derived planet parameters. PLATO will therefore monitor hundreds of thousands of stars for up to three years in order to fully characterize stars with asteroseismology and to detect transiting planets. The resulting large data set of stellar light curves provides an additional science return of the mission that reaches far beyond the exoplanet science case into stellar, Galactic, and extragalactic research. PLATO Payload features a multi-telescope configuration consisting of 26 cameras, of 12 cm pupil size aperture each, covering a field of view of about 2000 square degrees spread over 104 CCDs of 20 million pixels a piece. PLATO has strict noise requirements achieved through excellent optics transmission and quantum efficiency, low read-out noise, and stringent pointing requirements. In this talk we will review the drivers for PLATO Performance and present the most recent description of the status of noise budget and verification of main performance requirements (including field of view and pointing performance).

description: The number of bound states due to inhomogeneities in a BCS superconductor is usually established either by variational means or via exact solutions of particularly simple, symmetric perturbations. Here we propose estimating the number of sub-gap states using the Birman-Schwinger principle. We show how to obtain upper bounds on the number of sub-gap states for small normal regions and derive a suitable Cwikel-Lieb-Rozenblum inequality. We also estimate the number of such states for large normal regions using high dimensional generalizations of the Szego theorem. The method works equally well for local inhomogeneities of the order parameter and for external potentials.

description: We consider type II backgrounds of the form R^{1,d-1} x M^{10-d} for even d, preserving 2^{d/2} real supercharges; for d = 4, 6, 8 this is minimal supersymmetry in d dimensions, while for d = 2 it is N = (2,0) supersymmetry in two dimensions. For d = 6 we prove, by explicitly solving the Killing-spinor equations, that there is a one-to-one correspondence between background supersymmetry equations in pure-spinor form and D-brane generalized calibrations; this correspondence had been known to hold in the d = 4 case. Assuming the correspondence to hold for all d, we list the calibration forms for all admissible D-branes, as well as the background supersymmetry equations in pure-spinor form. We find a number of general features, including the following: The pattern of codimensions at which each calibration form appears exhibits a (mod 4) periodicity. In all cases one of the pure-spinor equations implies that the internal manifold is generalized Calabi-Yau. Our results are manifestly invariant under generalized mirror symmetry.

description: This paper analyzes higher education funding in Germany from a distributional perspective. For this, I first compare the quantitative importance of different funding instruments, from free tuition to subsidized health insurance for students. I show that free tuition is, by far, the most important instrument. Then, I take a lifetime perspective and assess how individuals of different expected lifetime incomes benefit from higher education funding. I distinguish between different fields of study as there are large differences in both the expected lifetime earnings of graduating from a specific field and the social cost of tuition associated with each field. Finally, I focus exclusively on the instrument of subsidized tuition and simulate the introduction of different tuition fee schemes with income-contingent loans. While the distributional effects would be sizable in absolute terms, I estimate that they would cause few individuals to change their educational decisions.
