description: To autonomously navigate and plan interactions in real-world environments, robots require the ability to robustly perceive and map complex, unstructured surrounding scenes. Besides building an internal representation of the observed scene geometry, the key insight toward a truly functional understanding of the environment is the usage of higher-level entities during mapping, such as individual object instances. We propose an approach to incrementally build volumetric object-centric maps during online scanning with a localized RGB-D camera. First, a per-frame segmentation scheme combines an unsupervised geometric approach with instance-aware semantic object predictions. This allows us to detect and segment elements both from the set of known classes and from other, previously unseen categories. Next, a data association step tracks the predicted instances across the different frames. Finally, a map integration strategy fuses information about their 3D shape, location, and, if available, semantic class into a global volume. Evaluation on a publicly available dataset shows that the proposed approach for building instance-level semantic maps is competitive with state-of-the-art methods, while additionally able to discover objects of unseen categories. The system is further evaluated within a real-world robotic mapping setup, for which qualitative results highlight the online nature of the method.

description: Nearly all theoretical analyses of the Maxwell's demon focus on its energetic and entropic costs of operation. Here, we focus on its rate of operation. In our model, a demon's rate limitation stems from its finite response time and gate area. We determine the rate limits of mass and energy transfer, as well as entropic reduction for four such demons: Those that select particles according to (1) direction, (2) energy, (3) number and (4) entropy. Lastly, we determine the optimal gate size for a demon with small, finite response time, and compare our predictions with molecular dynamics simulations with both ideal and non-ideal gasses. Lastly, we study the conditions under which the demons are able to move both energy and particles in the chosen direction when attempting to only move one.

description: Iron perovskites CaFeO_3 and La_{0.33}Sr_{0.67}FeO_3 show charge disproportionation, resulting in charge-ordered states with Fe^{3+}:Fe^{5+} =1:1 and =2:1, respectively. We have made photoemission and unrestricted Hartree-Fock band-structure calculation of CaFeO_3 and compared it with La_{0.33}Sr_{0.67}FeO_3. With decreasing temperature, a gradual decrease of the spectral weight near the Fermi level occurred in CaFeO_3 as in La_{0.33}Sr_{0.67}FeO_3 although lattice distortion occurs only in CaFeO_3. Hartree-Fock calculations have indicated that both the breathing and tilting distortions are necessary to induce the charge disproportionation in CaFeO_3, while no lattice distortion is necessary for the charge disproportionation in La_{0.33}Sr_{0.67}FeO_3.

description: It is a consequence of theorems of Gordon-Reid [Tangle decompositions of tunnel number one knots and links, J. Knot Theory and its Ramifications, 4 (1995) 389-409] and Thompson [Thin position and bridge number for knots in the 3-sphere, Topology, 36 (1997) 505-507] that a tunnel number one knot, if put in thin position, will also be in bridge position. We show that in such a thin presentation, the tunnel can be made level so that it lies in a level sphere. This settles a question raised by Morimoto [A note on unknotting tunnels for 2-bridge knots, Bulletin of Faculty of Engineering Takushoku University, 3 (1992) 219-225], who showed that the (now known) classification of unknotting tunnels for 2-bridge knots would follow quickly if it were known that any unknotting tunnel can be made level.

description: We describe the simulated data sample for the "Photometric LSST Astronomical Time Series Classification Challenge" (PLAsTiCC), a publicly available challenge to classify transient and variable events that will be observed by the Large Synoptic Survey Telescope (LSST), a new facility expected to start in the early 2020s. The challenge was hosted by Kaggle, ran from 2018 September 28 to 2018 December 17, and included 1,094 teams competing for prizes. Here we provide details of the 18 transient and variable source models, which were not revealed until after the challenge, and release the model libraries at https://doi.org/10.5281/zenodo.2612896. We describe the LSST Operations Simulator used to predict realistic observing conditions, and we describe the publicly available SNANA simulation code used to transform the models into observed fluxes and uncertainties in the LSST passbands (ugrizy). Although PLAsTiCC has finished, the publicly available models and simulation tools are being used within the astronomy community to further improve classification, and to study contamination in photometrically identified samples of type Ia supernova used to measure properties of dark energy. Our simulation framework will continue serving as a platform to improve the PLAsTiCC models, and to develop new models.

description: Geometric phases, accumulated when a quantum system traces a cycle in quantum state space, do not depend on the parametrization of the cyclic path, but do depend on the path itself. In the presence of noise that deforms the path, the phase gets affected, compromising the robustness of possible applications, e.g., in quantum computing. We show that for a special class of spin states, called anticoherent, and for paths that correspond to a sequence of rotations in physical space, the phase only depends on topological characteristics of the path, in particular, its homotopy class, and is therefore immune to noise.

description: Neutrino oscillations, biased by the magnetic field, alter the shape of the neutrinosphere in a cooling protoneutron star emerging from the supernova collapse. The resulting anisotropy in the momentum of outgoing neutrinos can be the origin of the observed proper motions of pulsars. The connection between the pulsars velocities and neutrino oscillations results in a prediction for the tau neutrino mass of order 100 eV.

description: Dynamics, the study of change, is normally the subject of mechanics. Whether the chosen mechanics is ``fundamental'' and deterministic or ``phenomenological'' and stochastic, all changes are described relative to an external time. Here we show that once we define what we are talking about, namely, the system, its states and a criterion to distinguish among them, there is a single, unique, and natural dynamical law for irreversible processes that is compatible with the principle of maximum entropy. In this alternative dynamics changes are described relative to an internal, ``intrinsic'' time which is a derived, statistical concept defined and measured by change itself. Time is quantified change.

description: Gauging the success of industrial reclamation requires targets to be set for restoring ecosystem structure and function. An indication of reclamation success is if wildlife recolonize, forage, rest, reproduce and survive on reclaimed areas. The grizzly bear is a threatened species that exists at low densities in Alberta, Canada and facilitates a variety of ecosystem processes. To make suggestions for mitigating the effects of open pit mining on this species, we collected and analysed biological data for grizzly bears on and around Cheviot, Luscar and Gregg River coal mines in west-central Alberta. During 2008-2010, we captured and attached GPS radiocollars on 12 adult bears on and around mines which allowed us to intensively track their movements. We visited bear used GPS locations in the field to assess bear activity and microhabitat characteristics. Bears selected reclaimed mines and areas near mines extensively in late spring and early summer to forage on forbs sown as part of mine reclamation and to depredate ungulate calves and lambs. In the fall, bears moved primarily in areas outside mines to forage on berries in preparation for winter denning. Bears often bedded in dense tree cover which underlines the importance of maintaining original vegetation patches in planning mine operations. The animals sometimes crossed the major active mine haul road and moved on and near trails designated for human access on mine leases. High mortality risk associated with expansion of human access into previously remote areas is a major threat to long-term persistence of the grizzly bear population. Defensive driving and potentially enforcement of speed restrictions on mine haul roads in areas with high frequency of bear crossings, provisioning for ecological movement corridors and proper waste management practices will help prevent human-bear conflict during the active mining phase. Following closure of mines, access management along designated trails will reduce the risk of conflicts. Imposing access restrictions, along with preserving undisturbed habitat patches and restoring the original vegetation cover will enable coexistence of people and bears on a shared landscape.

description: We define a Carmichael number of order m to be a composite integer n such that nth-power raising defines an endomorphism of every Z/nZ-algebra that can be generated as a Z/nZ-module by m elements. We give a simple criterion to determine whether a number is a Carmichael number of order m, and we give a heuristic argument (based on an argument of Erdos for the usual Carmichael numbers) that indicates that for every m there should be infinitely many Carmichael numbers of order m. The argument suggests a method for finding examples of higher-order Carmichael numbers; we use the method to provide examples of Carmichael numbers of order 2.

description: In this paper we study the thermopower of a quantum dot connected to two leads in the presence of Kondo correlation by employing a modified second-order perturbation scheme at nonequilibrium. A simple scheme, Ng's ansatz [Phys. Rev. Lett. {\bf 76}, 487 (1996)], is adopted to calculate nonequilibrium distribution Green's function and its validity is further checked with regard to the Onsager relation. Numerical results demonstrate that the sign of the thermopower can be changed by tuning the energy level of the quantum dot, leading to a oscillatory behavior with a suppressed magnitude due to the Kondo effect. We also calculate the thermal conductance of the system, and find that the Wiedemann-Franz law is obeyed at low temperature but violated with increasing temperature, corresponding to emerging and quenching of the Kondo effect.

Pigment Identification of Early Commercial Architectural Paint in Trade Catalogues: 1870-1914

description: What can early paint trade catalogues tell us about the beginnings of the commercial paint industry? Trade catalogues were originally produced advertising materials, but are now becoming a non-traditional tool for period architectural paint research. In order to garner the interest of the American consumer, paint manufacturers produced catalogues to promote and showcase their products. To do this these catalogues often used scenes depicting designs using their products, testimonials, or a collection of samples mounted inside. Many paint trade catalogues contained actual samples of the manufacturer's products, likely similar to those being sold to consumers. These catalogues were tested to understand the use of pigments as the paint industry developed in the late 19th and early twentieth century, leading to interesting and previously unknown findings about the paint industry during this period.

The study of commercial architectural paints is in its infancy, as most studies are focused on fine artists' paints and hand-mixed architectural paints. The research described in this paper begins to fill the hole in architectural paint research by using paint catalogues produced between 1870 and 1915 to test and identify the pigments used, looking to see if and how the use of pigments changed as the paint industry developed.

For this research, over 50 period paint catalogues, containing nearly 1500 samples and spanning almost 20 companies, were tested. This examination involved the technical analysis of the pigmentation present in the samples using a variety of methods, including Fourier transform infrared spectroscopy (FTIR), X-ray florescence (XRF), and polarized light microscopy (PLM). This testing was done not only to identify the pigments used, but also as an analysis of the testing methods for this particular type of investigation. The different strengths, advantages, and disadvantages of each test was noted, as different tests achieved different quality and types of results, with some tests being much more effective at gathering certain types of data than others.

The analysis of these samples revealed unexpected and fascinating results that would not have been achieved without a sampling of this size, showing sweeping similarities across the paint industry that had gone hitherto unnoticed as the paint industry developed into the large commercial enterprise that exists today.

Piloting Participatory Budgeting: An Examination of Social Capital, Well-Being, and Public Good Provision in New York City

Year: 2012
Subjects: Municipal budgets--Citizen participation

description: Participatory budgeting places the citizen in the role of the planner in an effort to improve public good provision and quality of life when resources are scarce. The process was instituted in New York City during a time when American citizens experienced increased inequality and a desire for more transparency in government. This case study is an examination of the pilot participatory budgeting process that was implemented in four New York City council districts from 2011 to 2012. An analysis of neighborhood assembly survey, nonparticipant observation, and project idea data suggest: 1. participatory budgeting can increase social capital; 2. it is unclear how much participatory budgeting affects the health and well-being of the community when such a small number of each community participated; 3. in general the participants already had a higher level of social capital entering the process; 4. inequality in social capital is evident when considering the public goods the residents are requesting; and 5. participatory budgeting risks maintaining or worsening inequality by empowering the powerful and not the disadvantaged. While social capital can work through public good provision to improve health and well-being, the unequal distribution of it may not help the people who need it the most. Ultimately, we must commit to being a just city by creating and implementing an overall equitable view, reconsidering the public goods and amenities allocation process, and focusing on social inclusion within our communities.

description: We prove existence of a countable family of spherically symmetric self-similar wave maps from 3+1 Minkowski spacetime into the 3-sphere. These maps can be viewed as excitations of the ground state wave map found previously by Shatah. The first excitation is particularly interesting in the context of the Cauchy problem since it plays the role of a critical solution sitting at the threshold of singularity formation. We analyze the linear stability of our wave maps and show that the number of unstable modes about a given map is equal to its excitation index. Finally, we formulate a condition under which these results can be generalized to higher dimensions.

The mine that almost closed : a review of fifteen years of reclamation at the Kitsault Mine, Alice Arm, British Columbia
Creators: name: Tashe, N.

Publisher: name: The University of British Columbia
Year: 2012

description: The Kitsault Mine, a molybdenum mine located on the northwest British Columbia coast at the end of Alice Arm, operated intermittently from 1968 until 1982 when low molybdenum prices and market conditions forced its shutdown. The mine operation was under a care and maintenance programme until 1996 when mine reclamation began with the development of a reclamation plan, implementation of mine facilities decommissioning and site preparation for revegetation. Revegetation and water quality goals were also addressed in the plan. The mine was on target to apply for a closure certificate, until redevelopment of the mine was announced in late 2008. This paper presents information on the successful implementation of the reclamation plan, particularly site revegetation, addresses how reclamation planning was used, and reports some of the lessons learned in revegetation efforts in mining.

description: It has been pointed out by Shlyakhter that data from the natural fission reactors which operated about two billion years ago at Oklo (Gabon) had the potential of providing an extremely tight bound on the variability of the fine-structure constant alpha. We revisit the derivation of such a bound by: (i) reanalyzing a large selection of published rare-earth data from Oklo, (ii) critically taking into account the very large uncertainty of the temperature at which the reactors operated, and (iii) connecting in a new way (using isotope shift measurements) the Oklo-derived constraint on a possible shift of thermal neutron-capture resonances with a bound on the time variation of alpha. Our final (95% C.L.) results are: -0.9 \times 10^{-7}

description: With the rapid pace of urbanization in China, it becomes more and more important for urban planners to explore the planning issues existing in urban villages, which are the semi-urbanized spatial entities with collective land ownership regime in urban China. Place attachment is widely researched in planning field, which is used to describe the people-place connections. In this thesis, I explored residents' attachment in a typical urban village in Guangzhou using both quantitative and qualitative methods. Through surveys, I found residents in Zhu Village have moderate attachments to the place they live in, and some significant differences were identified based on variables like local status and length of residence. The results of interviews reveal that the locals hold a higher level of emotional attachment while the non-locals tend to show a strong feeling of place dependence. For locals, the emotional connections are anchored deeply in the culture, consanguinity and power worship to the village while emotional associations of non-locals are formed on the basis of the deep or shallow cognitions to a place. As for functional attachment, locals emphasize the functional connections in relation to activities with place-specific meanings. But for non-locals, whether the residence could satisfy their general needs for living is key to the formation of their functional attachment.

description: School closures can have enormous effects on students and families living in a neighborhood. School districts in many urban areas in the United States have recently been faced with the challenge of how to deal with a shrinking school-aged population, budget crises, aging facilities and poor academic performance. This has led some districts to close large numbers of school buildings. A prime example occurred in Pittsburgh, Pennsylvania in 2006. This research will examine changes in population count, racial composition, and housing characteristics in three affected neighborhoods of Pittsburgh following the decision by the Pittsburgh Board of Education to close 22 schools that year. The research will examine how large vacant facilities affect the neighborhood’s physical and social dynamics. Data analysis, interviews and site analysis help to answer the research questions. The findings suggest that school vacancies have a negative effect on neighborhoods to varying degrees, and the neighborhood’s ability to cope with this loss is determined by a number of factors such as desirability of the area and community resources. Recommendations can help other cities to better plan for closures in the future to ensure the most equitable outcomes.

The graviton background at early times in string cosmology
Creators: name: Maggiore, Michele
Publisher: name: arXiv
Year: 1997
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We discuss some peculiar properties of the stochastic graviton background predicted by string cosmology. At Planckian times, for the values of the parameters of the model which are more interesting for the detection in gravitational wave experiments, the number density of gravitons is parametrically large compared to Planck density, and is peaked at small energies. The large parameter is related to the duration of the string phase and is a characteristic of string cosmology. The typical interaction time is parametrically larger than the Planck or string time. Therefore the shape of the graviton spectrum is not distorted by thermal effects in the Planck era and can carry informations on the pre-big bang phase suggested by string cosmology.

Energy equipartition between stellar and dark matter particles in cosmological simulations results in spurious growth of galaxy sizes

description: The impact of 2-body scattering on the innermost density profiles of dark matter haloes is well established. We use a suite of cosmological simulations and idealised numerical experiments to show that 2-body scattering is exacerbated in situations where there are two species of unequal mass. This is a consequence of mass segregation and reflects a flow of kinetic energy from the more to less massive particles. This has important implications for the interpretation of galaxy sizes in cosmological hydrodynamic simulations, which nearly always model stars with less massive particles than are used for the dark matter. We compare idealised models as well as simulations from the EAGLE project that differ only in the mass resolution of the dark matter component, but keep sub-grid physics, baryonic mass resolution and gravitational force softening fixed. If the dark matter particle mass exceeds the mass of stellar particles, then galaxy sizes--quantified by their projected half-mass radii, ${\rm R_{50}}$--increase systematically with time until ${\rm R_{50}}$ exceeds a small fraction of the redshift-dependent mean inter-particle separation, $l$ (${\rm R_{50}}\geq 0.05\times l$). Our conclusions should also apply to simulations that adopt different hydrodynamic solvers, subgrid physics or adaptive softening, but in that case may need quantitative revision. Any simulation employing a stellar-to-dark matter particle mass ratio greater than unity will escalate spurious energy transfer from dark matter to baryons on small scales.

description: We advocate an alternative description of canonical gravity in 3+1 dimensions, obtained by using as the basic variable a real variant of the usual Ashtekar connection variables on the spatial three-manifold. With this ansatz, no non-trivial reality conditions have to be solved, and the Hamiltonian constraint, though non-polynomial, can be quantized rigorously in a lattice regularization.

Planarity and the mean curvature flow of pinched submanifolds in higher codimension

description: In this thesis, we explore the role of planarity in mean curvature flow in higher codimension and investigate its implications for singularity formation in a certain class of flows. In Chapter 1, we show that the blow-ups of compact 𝑛-dimensional solutions to mean curvature flow in ℝⁿ initially satisfying the pinching condition |𝐴|² < c |𝐻|² for a suitable constant c = c(𝑛) must be codimension one. We do this by establishing a new a priori estimate via a maximum principle argument. In Chapter 2, we consider ancient solutions to the mean curvature flow in ℝⁿ⁺¹ (𝑛 ≥ 3) that are weakly convex, uniformly two-convex, and satisfy derivative estimates |∇𝐴| ≤ 𝛾1 |𝐻|², |∇² 𝐴| \leq 𝛾2 |𝐻|³. We show that such solutions are noncollapsed. The proof is an adaptation of the foundational work of Huisken and Sinestrari on the flow of two-convex hypersurfaces. As an application, in arbitrary codimension, we classify the singularity models of compact 𝑛-dimensional (𝑛 ≥ 5) solutions to the mean curvature flow in ℝⁿ that satisfy the pinching condition |𝐴|² < c |𝐻|² for c = min {1/𝑛-2, 3(𝑛+1)/2𝑛(𝑛+2)}. Using recent work of Brendle and Choi, together with the estimate of Chapter 1, we conclude that any blow-up model at the first singular time must be a codimension one shrinking sphere, shrinking cylinder, or translating bowl soliton. Finally, in Chapters 3 and 4, we prove a canonical neighborhood theorem for the mean curvature flow of compact 𝑛-dimensional submanifolds in ℝⁿ (𝑛 ≥ 5) satisfying a pinching condition |𝐴|² < c |𝐻|² for $c = min {1/𝑛-2, 3(𝑛+1)/2𝑛(𝑛+2)}. We first discuss, in some detail, a well-known compactness theorem of the mean curvature flow. Then, adapting an argument of Perelman and using the conclusions of Chapter 2, we characterize regions of high curvature in the pinched solutions of the mean curvature flow under consideration.
