description: Achieving robust multi-person 2D body landmark localization and pose estimation is essential for human behavior and interaction understanding as encountered for instance in HRI settings. Accurate methods have been proposed recently, but they usually rely on rather deep Convolutional Neural Network (CNN) architecture, thus requiring large computational and training resources. In this paper, we investigate different architectures and methodologies to address these issues and achieve fast and accurate multi-person 2D pose estimation. To foster speed, we propose to work with depth images, whose structure contains sufficient information about body landmarks while being simpler than textured color images and thus potentially requiring less complex CNNs for processing. In this context, we make the following contributions. i) we study several CNN architecture designs combining pose machines relying on the cascade of detectors concept with lightweight and efficient CNN structures; ii) to address the need for large training datasets with high variability, we rely on semi-synthetic data combining multi-person synthetic depth data with real sensor backgrounds; iii) we explore domain adaptation techniques to address the performance gap introduced by testing on real depth images; iv) to increase the accuracy of our fast lightweight CNN models, we investigate knowledge distillation at several architecture levels which effectively enhance performance. Experiments and results on synthetic and real data highlight the impact of our design choices, providing insights into methods addressing standard issues normally faced in practical applications, and resulting in architectures effectively matching our goal in both performance and speed.

description: For most finite element simulations, boundary-conforming meshes have significant advantages in terms of accuracy or efficiency. This is particularly true for complex domains. However, with increased complexity of the domain, generating a boundary-conforming mesh becomes more difficult and time consuming. One might therefore decide to resort to an approach where individual boundary-conforming meshes are pieced together in a modular fashion to form a larger domain. This paper presents a stabilized finite element formulation for fluid and temperature equations on sliding meshes. It couples the solution fields of multiple subdomains whose boundaries slide along each other on common interfaces. Thus, the method allows to use highly tuned boundary-conforming meshes for each subdomain that are only coupled at the overlapping boundary interfaces. In contrast to standard overlapping or fictitious domain methods the coupling is broken down to few interfaces with reduced geometric dimension. The formulation consists of the following key ingredients: the coupling of the solution fields on the overlapping surfaces is imposed weakly using a stabilized version of Nitsche's method. It ensures mass and energy conservation at the common interfaces. Additionally, we allow to impose weak Dirichlet boundary conditions at the non-overlapping parts of the interfaces. We present a detailed numerical study for the resulting stabilized formulation. It shows optimal convergence behavior for both Newtonian and generalized Newtonian material models. Simulations of flow of plastic melt inside single-screw as well as twin-screw extruders demonstrate the applicability of the method to complex and relevant industrial applications.

description: Problem, research strategy, and findings: Local governments can secure valuable public benefits from private real estate development through negotiations or schedule-based exaction programs. Nevertheless, few studies have empirically examined their relative strengths and weaknesses. In this study I compare the experiences of two major U.S. cities, Boston (MA)—where exactions are heavily negotiated—and Seattle (WA)—where public benefits are secured through statutory exaction programs with pre-established schedules. I analyze the entitlement processes of large-scale projects approved in 2016 in each city and show that both approaches have their own strengths and weaknesses. Boston was able to extract substantial public benefit packages, but uncertainty was high, and projects were subject to inconsistent decision making at times. By contrast, Seattle’s schedule-based approach was found to be fair and certain while yielding moderate public benefit packages. Despite the commonly held belief that negotiating land uses on a project-by-project basis is associated with significant process delays and a lack of transparency, the case of Boston offers a different perspective. Boston’s projects were approved in a shorter time frame and were subjected to more public meetings per project than Seattle’s. Takeaway for practice: U.S. local governments are likely to rely on both negotiations and schedules to extract public benefits from real estate developments. Though schedule-based exaction programs ensure overall fairness and certainty of the entitlement process, project-by-project negotiation could potentially yield significant public benefits. However, uncertainty can be high in a negotiation-heavy system, which may disadvantage small-scale developers. Moreover, negotiations may open up room for poor and inconsistent decision making, which must be mitigated by establishing clear policies and standards to guide the negotiation process. Both negotiation and schedule-based processes can be designed to ensure a transparent process with multiple public participation opportunities.

description: Link prediction is an important and frequently studied task that contributes to an understanding of the structure of knowledge graphs (KGs) in statistical relational learning. Inspired by the success of graph convolutional networks (GCN) in modeling graph data, we propose a unified GCN framework, named TransGCN, to address this task, in which relation and entity embeddings are learned simultaneously. To handle heterogeneous relations in KGs, we introduce a novel way of representing heterogeneous neighborhood by introducing transformation assumptions on the relationship between the subject, the relation, and the object of a triple. Specifically, a relation is treated as a transformation operator transforming a head entity to a tail entity. Both translation assumption in TransE and rotation assumption in RotatE are explored in our framework. Additionally, instead of only learning entity embeddings in the convolution-based encoder while learning relation embeddings in the decoder as done by the state-of-art models, e.g., R-GCN, the TransGCN framework trains relation embeddings and entity embeddings simultaneously during the graph convolution operation, thus having fewer parameters compared with R-GCN. Experiments show that our models outperform the-state-of-arts methods on both FB15K-237 and WN18RR.

description: We describe an ultra-wide-bandwidth, low-frequency receiver ("UWL") recently installed on the Parkes radio telescope. The receiver system provides continuous frequency coverage from 704 to 4032 MHz. For much of the band (~60%) the system temperature is approximately 22K and the receiver system remains in a linear regime even in the presence of strong mobile phone transmissions. We discuss the scientific and technical aspects of the new receiver including its astronomical objectives, as well as the feed, receiver, digitiser and signal-processor design. We describe the pipeline routines that form the archive-ready data products and how those data files can be accessed from the archives. The system performance is quantified including the system noise and linearity, beam shape, antenna efficiency, polarisation calibration and timing stability.

Individually, each provides an important constraint to any given model; in concert, the four represent a fundamental (intractable) boundary condition for chemodynamical simulations. We review the current state-of-the-art semi-analytical and chemodynamical models for the Milky Way, emphasising the strengths and weaknesses of both approaches.

description: We study the formation and evolution of HII regions around the first stars formed at z=10-30. We use a one-dimensional Lagrangian hydrodynamics code which self-consistently incorporates radiative transfer and non-equilibrium primordial gas chemistry. The star-forming region is defined as a spherical gas cloud with a Population III star embedded at the center. We explore a large parameter space of host halo mass, gas density profile, and stellar luminosity. The formation of the HII region is characterized by initial slow expansion of a weak D-type ionization front near the center, followed by rapid propagation of an R-type front throughout the outer gas envelope. We find that the transition between the two front types is indeed a critical condition for the complete ionization of halos of cosmological interest. In small mass (< 10^6 M_sun) halos, the transition takes place within a few 10^5 yr, yielding high escape fractions (>80%) of both ionizing and photodissociating photons. In larger mass (> 10^7 M_sun) halos, the ionization front remains to be of D-type over the lifetime of the massive star, the HII region is confined well inside the virial radius, and the escape fractions are essentially zero. We derive an analytic formula that reproduces well the results of our simulations. We discuss immediate implications of the present results for the star formation history and early reionization of the Universe.

description: We present images of the young stellar object ASR 41 in the NGC 1333 star forming region at the wavelengths of H_alpha and [SII] and in the I, J, H, and K-bands. ASR 41 has the near-infrared morphology of an edge-on disk object, but appears an order of magnitude larger than typical systems of this kind. We also present detailed models of the scattering and radiative transfer in systems consisting of a young star surrounded by a proto-planetary disk, and the whole system being embedded in either an infalling envelope or a uniform molecular cloud. The best fit to the observed morphology can be achieved with a disk of approx. 200 AU diameter, immersed in a low density cloud. The low cloud density is necessary to stay below the sub-mm flux upper limits and to preserve the shadow cast by the disk via single scattering. The results demonstrate that ASR 41 is probably not inherently different from typical edge-on disk objects, and that its large apparent size is due to the shadow of a much smaller disk being projected into the surrounding dusty molecular material.
A Precision Measurement of the Mass of the Top Quark

description: The Standard Model of particle physics contains about two dozen parameters - such as particle masses - whose origins are still unknown and cannot be predicted, but whose values are constrained through their interactions. In particular, the masses of the top (t) quark (M_t) and W boson constrain the mass of the long-hypothesized, but thus far not observed, Higgs boson. A precise measurement of the top-quark mass can therefore point to where to look for the Higgs, and indeed whether the hypothesis of a SM Higgs is consistent with experimental data. Since top quarks are produced in pairs and decay in only ~10^-24 s into various final states, reconstructing their mass from their decay products is very challenging. Here we report a technique that extracts far more information from each top-quark event and yields a greatly improved precision on the top mass of 5.3 GeV/c^2, compared to previous measurements. When our new result is combined with our published measurement in a complementary decay mode and with the only other measurements available, the new world average for M_t becomes 178.0 +- 4.3 GeV/c^2. As a result, the most likely Higgs mass increases from the experimentally excluded value of 96 GeV/c^2 to 117 GeV/c^2, which is beyond current experimental sensitivity. The upper limit on the Higgs mass at 95% confidence level is raised from 219 GeV/c^2 to 251 GeV/c^2.

It contains information and exercises in assessing a board in three ways: (1) director’s selfassessment (assesses seven areas related to a director’s responsibilities and duties), (2) assessing the cooperative board as a single entity (assesses how well directors work together), and (3) assessing board meetings (measuring the productivity and effectiveness of meetings). Cooperative boards can use assessments to identify problem areas and weaknesses and subsequently devise programs, plans, and training methods to remedy them. An assessment should be conducted regularly. Improvements should be made and progress tracked.

description: Novel guanine nucleotide analogues have been used to investigate the role of Mg2+ in nucleotide release and binding with the small G protein rac. The fluorescent analogues have 7-(ethylamino)-8-bromocoumarin-3-carboxylic acid attached to the 3‘-position of the ribose via an ethylenediamine linker. This modification has only small effects on the interaction with rac. There are large fluorescence changes on binding of the triphosphate to rac, on hydrolysis, and then on release of the diphosphate. Furthermore, the fluorescence is sensitive to the presence of Mg2+ in the active site. Using this signal, it was shown that, for a variety of conditions, the nucleotides dissociate by a two-step mechanism. Mg2+ is released first followed by the nucleotide. With the diphosphate, Mg2+ is fast and nucleotide release slow. For the fluorescent GMPPNP analogue, the rate of dissociation is limited by Mg2+ release. In the latter case …

description: A one-dimensional and stationary reactor model is presented to describe the catalytic conversion of a gaseous hydrocarbon fuel with air and steam to synthesis gas by autothermal reforming (ATR) and catalytic partial oxidation (CPO). The model defines two subsequent sections in the reactor, namely an upstream oxidation section, and a downstream reforming section. In the oxidation section all of the oxygen is converted, with partial conversion of the fuel. An empirical fuel utilization ratio is used to quantify which part of the fuel is converted in the oxidation section as function of the relative flows of air and steam. In the oxidation section, the gas temperature rapidly increases toward the toptemperature at the intersection with the reforming section. In this section the temperature decreases while the fuel is further converted with water and CO2 as oxidant. For methane as fuel, simulation results are presented and compared with experiments. For multicomponent fuels such as natural gas and naphtha, it is described how the two-section model can be applied.

description: Individual rate constants have been determined for each step of the Ras·GTP hydrolysis mechanism, activated by neurofibromin. Fluorescence intensity and anisotropy stopped-flow measurements used the fluorescent GTP analogue, mantGTP (2‘(3‘)-O-(N-methylanthraniloyl)GTP), to determine rate constants for binding and release of neurofibromin. Quenched flow measurements provided the kinetics of the hydrolytic cleavage step. The fluorescent phosphate sensor, MDCC-PBP was used to measure phosphate release kinetics. Phosphate−water oxygen exchange, using 18O-substituted GTP and inorganic phosphate (Pi), was used to determine the extent of reversal of the hydrolysis step and of Pi binding. The data show that neurofibromin and Pi dissociate from the NF1·Ras·GDP·Pi complex with identical kinetics, which are 3-fold slower than the preceding cleavage step. A model is presented in which the Pi …

description: The distant ice giants of the Solar System, Uranus and Neptune, have only been visited by one space mission, Voyager 2. The current knowledge on their composition remains very limited despite some recent advances. A better characterization of their composition is however essential to constrain their formation and evolution, as a significant fraction of their mass is made of heavy elements, contrary to the gas giants Jupiter and Saturn. An in situ probe like Galileo would provide us with invaluable direct ground-truth composition measurements. However, some of the condensibles will remain out of the grasp of a shallow probe. While additional constraints could be obtained from a complementary orbiter, thermochemistry and diffusion modeling can further help us to increase the science return of an in situ probe.

description: Following the announcement of the President's program of voluntary wage and price standards in October 1978, a food price monitoring program was established in the Economics, Statistics, and Cooperatives Service (ESCS) of USDA in cooperation with the Council on Wage and Price Stability (CWPS). The responsibilities of the food price monitoring effort initially included (1) the monitoring of price changes at various levels in the food system (2) the identification of significant movements in food prices, and (3) the development of policy alternatives to reduce inflation in the food sector of the economy. Since October, these functions have been expanded and now include margins monitoring.

description: Recent structural VAR studies of the monetary transmission mechanism have voiced concerns about the use of recursive identification schemes based on short-run exclusion restrictions. We trace out the effects on impulse propagation of informational constraints embodying classical Cholesky-timing restrictions in otherwise standard Dynamic New Keynesian (DNK) models. By reinforcing internal propagation mechanisms and enlarging a model's equilibrium state space, timing restrictions may produce a non-trivial moving average component of the equilibrium representation, making finite order VARs a poor approximation of true adjustment paths to monetary impulses, albeit correctly identified. They can even serve as an independent source of model-based nonfundamentalness, thereby hampering shock identification via VAR methods. This notwithstanding, restricted DNK models are shown to feature (i) invertible equilibrium representations for the observables and (ii) fast-converging VAR coefficient matrices under empirically tenable parameterizations. This alleviates concerns about identification and lag truncation bias: low-order Cholesky-VARs do well at uncovering the transmission of monetary impulses in a truly Cholesky world.

Using the Very Large Array, we simultaneously observed the v=0, J=1-0, 43.4-GHz, ground-state and the v=1, J=1-0, 43.1-GHz, first excited-state transitions of SiO toward the oxygen-rich evolved stars IRC+10011, o Ceti, W Hya, RX Boo, NML Cyg, and R Cas and the S-type star chi Cyg. We detected at least one v=0 SiO maser feature from six of the seven stars observed, with peak maser brightness temperatures ranging from 10,000 K to 108,800 K. In fact, four of the seven v=0 spectra show multiple maser peaks, a phenomenon which has not been previously observed. Ground-state thermal emission was detected for one of the stars, RX Boo, with a peak brightness temperature of 200 K. Comparing the v=0 and the v=1 transitions, we find that the ground-state masers are much weaker with spectral characteristics different from those of the first excited-state masers. For four of the seven stars the velocity dispersion is smaller for the v=0 emission than for the v=1 emission, for one star the dispersions are roughly equivalent, and for two stars (one of which is RX Boo) the velocity spread of the v=0 emission is larger. In most cases, the peak flux density in the v=0 emission spectrum does not coincide with the v=1 maser peak. Although the angular resolution of these VLA observations were insufficient to completely resolve the spatial structure of the SiO emission, the SiO spot maps produced from the interferometric image cubes suggest that the v=0 masers are more extended than their v=1 counterparts.

description: To be given at a meeting of professional economists, the subject of this paper implies (1) a gap between the subject matter and emphasis of current research, (2) a lack of communications between those doing research and those in industry who are impatient for answers to constantly changing problems, or (3) both. And, while the nature of institutional research and the nature of economics training have been perennial themes of industry sessions at these meetings, increasingly there are similar challenges coming from professionals in academia and government.
FORCES INFLUENCING RURAL COMMUNITY GROWTH

description: This panel is to focus on three questions: What is happening demographically in the rural areas of the United States? Can the recent growth trend be expected to continue into the future? And, what does this imply as far as public policy and programs are concerned? The first question has been dealt with very capably here and elsewhere by Calvin Beale. There is little room to doubt his statistical evidence. As the latter two questions lend themselves more to non-statistical arguments and as I have little data, I will concentrate on them.

description: The thesis of the paper is that there is a need for social science researchers and community development practitioners to focus on the fundamental problem of the loss of a sense of community in American life (we define sense of community as the existence of shared meaning and trust among individuals). We see the problems of environmental quality, provision of public services and concerns about other factors considered to be in the rubric of quality of life as symptomatic of this fundamental breakdown in community. The erosion of community is being accompanied by increasing attempts to maintain or strengthen organizational/institutional structures. We see these attempts as furthering destruction of community.

description: During the past five years, the popularity of the rural development movement has waned considerably. The reasons for diminished RD support among both public officials and researchers are numerous and complex, but the failure to adequately incorporate institutional change into research on community resource allocation must be regarded as one of the movement's major disappointments.

description: In a paper presented at these meetings two years ago, Back argued that "the unsatisfactory state of rural development policy reflects in part either an inadequate or inaccessible knowledge base" (p. 1125). Basically, Back was arguing that research in rural, development had not provided policy-makers with the information necessary to formulate a cohesive national rural development policy. In addition, he argued that the reason for the "knowledge gap" is the institutional arrangements for conducting rural development research.

description: This paper briefly reviews the process of artificial orthogonalization and component deletion in regression analysis. Confusion seems to exist over which elements to delete in -the orthogonal frame of analysis. This paper developed theory of component deletion via the characteristic root and t-value and interprets the meaning of each criterion. A simulation model is employed.

description: Individual rate constants have been determined for each step of the Ras·GTP hydrolysis mechanism, activated by neurofibromin. Fluorescence intensity and anisotropy stopped-flow measurements used the fluorescent GTP analogue, mantGTP (2‘(3‘)-O-(N-methylanthraniloyl)GTP), to determine rate constants for binding and release of neurofibromin. Quenched flow measurements provided the kinetics of the hydrolytic cleavage step. The fluorescent phosphate sensor, MDCC-PBP was used to measure phosphate release kinetics. Phosphate−water oxygen exchange, using 18O-substituted GTP and inorganic phosphate (Pi), was used to determine the extent of reversal of the hydrolysis step and of Pi binding. The data show that neurofibromin and Pi dissociate from the NF1·Ras·GDP·Pi complex with identical kinetics, which are 3-fold slower than the preceding cleavage step. A model is presented in which the Pi …
The Effect of Proton Temperature Anisotropy on the Solar Minimum Corona and Wind

description: A semi-empirical, axisymmetric model of the solar minimum corona is developed by solving the equations for conservation of mass and momentum with prescribed anisotropic temperature distributions. In the high-latitude regions, the proton temperature anisotropy is strong and the associated mirror force plays an important role in driving the fast solar wind; the critical point where the outflow velocity equals the parallel sound speed is reached already at 1.5 Rsun from Sun center. The slow wind arises from a region with open field lines and weak anisotropy surrounding the equatorial streamer belt. The model parameters were chosen to reproduce the observed latitudinal extent of the equatorial streamer in the corona and at large distance from the Sun. We find that the magnetic cusp of the closed-field streamer core lies at about 1.95 Rsun. The transition from fast to slow wind is due to a decrease in temperature anisotropy combined with the non-monotonic behavior of the non-radial expansion factor in flow tubes that pass near the streamer cusp. In the slow wind, the plasma beta is of order unity and the critical point lies at about 5 Rsun, well beyond the magnetic cusp. The predicted outflow velocities are consistent with OVI Doppler dimming measurements from UVCS/SOHO. We also find good agreement with polarized brightness (pB) measurements from LASCO/SOHO and HI Ly-alpha images from UVCS/SOHO.

description: The hydrogen fluoride (HF) molecule is seen in absorption in the interstellar medium (ISM) along many lines of sight. Surprisingly, it is observed in emission toward the Orion Bar, which is an interface between the ionized region around the Orion Trapezium stars and the Orion molecular cloud. We aim to understand the origin of HF emission in the Orion Bar by comparing its spatial distribution with other tracers. We examine three mechanisms to explain the HF emission: thermal excitation, radiative dust pumping, and chemical pumping. We used a Herschel/HIFI strip map of the HF J = 1-0 line, covering 0.5' by 1.5' that is oriented perpendicular to the Orion Bar. We used the RADEX non-local thermodynamic equilibrium (non-LTE) code to construct the HF column density map. We use the Meudon PDR code to explain the morphology of HF. The bulk of the HF emission at 10 km s^-1 emerges from the CO-dark molecular gas that separates the ionization front from the molecular gas that is deeper in the Orion Bar. The excitation of HF is caused mainly by collisions with H2 at a density of 10^5 cm^-3 together with a small contribution of electrons in the interclump gas of the Orion Bar. Infrared pumping and chemical pumping are not important. We conclude that the HF J = 1-0 line traces CO-dark molecular gas. Similarly, bright photodissociation regions associated with massive star formation may be responsible for the HF emission observed toward active galactic nuclei.

description: A solvmanifold is a compact differentiable manifold M on which a connected solvable Lie group G acts transitively. As the main result, we will see, applying a result of Arapura and Nori on solvable Kaehler groups and some of the author's previous results, that a compact solvmanifold admits a Kaehler structure if and only if it is a finite quotient of a complex torus which has a structure of a complex torus bundle over a complex torus. There are also quite a few comments and remarks on and around this result.

description: We use a Heisenberg spin-1/2 chain to investigate how chaos and localization may affect the entanglement of pairs of qubits. To measure how much entangled a pair is, we compute its concurrence, which is then analyzed in the delocalized/localized and in the chaotic/non-chaotic regimes. Our results indicate that chaos reduces entanglement and that entanglement decreases in the region of strong localization. In the transition region from a chaotic to a non-chaotic regime localization increases entanglement. We also show that entanglement is larger for strongly interacting qubits (nearest neighbors) than for weakly interacting qubits (next and next-next neighbors).
