description: Growing significance of environmentalism in today’s culture has given way to the environment-conscious young generation rising up with youth-led movements and initiatives. While the realization of practical actions may vary from one urban area to another, New York City, with its 2030 Zero Waste goal, can capitalize on this momentum to widely execute the program’s key initiative: composting. To that end, this research seeks to identify the factors that New York City's residents face when attempting to compost and explores possible interventions the City can implement to bolster community engagement. With the young generation’s demonstrated responsibility and sensitivity to trending environmental issues, the research aims particularly at those aged 20-39 to be effective conduits of the social movement. Online survey responses were collected from those identified as the target group via popular social network platforms. The quantitative data was further complemented by in-person interviews of the City residents, volunteers and staff at relevant organizations. The findings suggest that the low participation rate in composting programs can be overcome by addressing the following prominent barriers:​ 𝘭𝘢𝘤𝘬 𝘰𝘧 𝘢𝘤𝘤𝘦𝘴𝘴​ to composting sites, ​𝘭𝘪𝘮𝘪𝘵𝘦𝘥 𝘬𝘯𝘰𝘸𝘭𝘦𝘥𝘨𝘦 𝘢𝘯𝘥 𝘪𝘯𝘵𝘦𝘳𝘦𝘴𝘵 ​on the topic, and ​𝘱𝘦𝘳𝘤𝘦𝘪𝘷𝘦𝘥 𝘪𝘯𝘤𝘰𝘯𝘷𝘦𝘯𝘪𝘦𝘯𝘤𝘦𝘴​. Starting with the City’s young people, the concept of “nudging” can be employed to influence their proactive behavior and allow their participation in the composting program to be the source of inspiration to other age groups in realizing the 2030 Zero Waste goal.

description: As Naturally Occurring Retirement Communities (NORCs) gain support as an aging-in-place approach to senior housing, it is important to consider the impact of existing building infrastructure on aging residents. By definition, NORCs are unplanned and undesigned. New York City and State define eligibility of NORC legislative designation to be a building or complex constructed with government assistance with a high concentration of seniors but not specifically built for seniors. While NORC social and health services provide unique assistance to these groups of seniors, the challenge of adapting the physical spaces of NORCs in order to assist aging are rarely discussed. This paper is a case study of a NORC identified within a New York City Housing Authority development and analyzes the benefits and challenges that “place” brings to both the residents and the service providers in an aging-in-place model. This qualitative approach seeks to collect experiences and perspectives of the daily life of NORC residents from both a neighborhood scale and a building scale in order to evaluate the aging experience within the embedded physical infrastructure and address the question, what is the level of need for physical improvements within this NORC context? Through its findings, this paper proposes a series of recommendations from multiple vantage points that addresses the issue at different scales, some involving holistic healthy aging.

description: We investigate the electronic structure of Nickel sulphide (NiS) in the millerite phase using electron spectroscopic measurements and band structure as well as model Hamiltonian calculations. While band structure calculations are found to be relatively more successful in describing the experimental valence band spectrum of this highly conducting phase compared to the hexagonal phase of NiS, cluster calculations including electron correlation effects are found to be necessary for the description of certain features in the experimental spectra, indicating importance of correlation effects even in a highly metallic system. The electronic parameter strengths obtained from these calculations confirm that the millerite NiS is a highly covalent pd-metal. The comparative study of hexagonal and millerite forms of NiS, provides the information concerning the evolution of the spectral function in a pd-metal as a function of covalency.

Planning with Character: Gotouchi Kyara and Place Branding in Japan

Subjects: subject: City planning

description: As part of urban planning, local governments in Japan have developed a unique type of city branding that uses gotouchi kyara ご当地キャラ, which are community character mascots representing cities, towns, or villages that highlight significant aspects of the area, such as famous foods or tourist attractions. The character mascots tap into the already present character goods and kawaii culture of Japan, are cost effective and sustainable, are a means for bringing the community residents together, and easily lend themselves to local economic development. Thus, the character mascots are a major strategy for place branding. A geographical information system (GIS) cluster analysis suggests that the origin of gotouchi kyara in Japan was dispersed in the early 1980s, became random in the 1990s, and began to cluster in the mid-2000s. Clusters that are far apart from each other can be found throughout Japan, and hot spots of multiple gotouchi kyara are found in the smaller cities, towns, and villages in the south of Japan and cold spots are found near Tokyo. The proliferation of gotouchi kyara is most dense around the major metropolitan areas. Criticism exists for the mascots, but “character power” is undeniable in contemporary Japanese society.

description: We analyze the situation of a local quantum field theory with constraints, both indexed by the same set of space-time regions. In particular we find ``weak'' Haag-Kastler axioms which will ensure that the final constrained theory satisfies the usual Haag-Kastler axioms. Gupta-Bleuler electromagnetism is developed in detail as an example of a theory which satisfies the ``weak'' Haag-Kastler axioms but not the usual ones. This analysis is done by pure C*-algebraic means without employing any indefinite metric representations, and we obtain the same physical algebra and positive energy representation for it than by the usual means. The price for avoiding the indefinite metric, is the use of nonregular representations and complex valued test functions. We also exhibit the precise connection with the usual indefinite metric representation. We conclude the analysis by comparing the final physical algebra produced by a system of local constrainings with the one obtained from a single global constraining and also consider the issue of reduction by stages. For the usual spectral condition on the generators of the translation group, we also find a ``weak'' version, and show that the Gupta-Bleuler example satisfies it.

description: Urban agriculture is transitioning from a predominantly fringe activity into a land classification with increasingly mainstream appeal for achieving neighborhood improvements. Cities around the world have reversed earlier positions prohibiting agricultural uses on urban land. Some, such as Baltimore, MD have gone even further into a full embrace of urban agriculture in hopes of reaping the social, economic and environmental benefits touted by urban agriculture advocates. This study takes a qualitative look at Baltimore’s plan to expand and support urban agriculture through a formal plan: Grow Local. The plan was written with the intent to help Baltimore create an environment that facilitates urban agricultural practice. This study examines and challenges the robustness of the Grow Local plan, and attempts to identify critical barriers to implementation to date. The research attempts to answer the question of whether planning for urban agriculture is relevant and if so, how can other cities learn from the implementation challenges facing the city of Baltimore.
Teck's Coal business unit applied research and development program - a watershed approach

description: Teck’s Coal business unit is embarking on a comprehensive, applied research and development (R&D) initiative that will provide information to support management decisions with respect to mine design changes that will support the objective of maintaining watershed function in perpetuity, at all of Teck’s coal mining operations. The program will involve laboratory, pilot, prototype and commercial scale studies to ensure that results of technology testing are demonstrated and that indicators of watershed function (hydrologic and biogeochemical, in the short term), are established and verified at the dump, mine, and watershed scales. Projects within the program will be undertaken at all of Teck’s operations in the Elk Valley of southeast B.C., and at our Cardinal River Operations in Alberta. The projects are being undertaken in partnership with a team of industry and University-based research scientists and engineers. The program is a multi-year initiative designed to actively support mine planning and closure planning decisions on an ongoing basis through a developed technology transfer process. The overall applied R&D program is being developed using the US Environmental Protection Agency (EPA) Data Quality Objectives (DQO) process as a guide. The DQO process is used to develop performance and acceptance criteria (or data quality objectives) that clarify study objectives, define the appropriate type of data, and specify tolerable levels of potential decision errors that will be used as the basis for establishing the quality and quantity of data needed to support decisions (EPA QA/G-4 2006). Teck is employing the DQO process at various levels to assemble the research program and to clearly link the research to management decisions and mine planning activities. The applied R&D program is a multi-disciplinary program with a selenium (Se) and watershed focus. It integrates applied research in the areas of biogeochemistry, water balance (hydrology, hydrogeology), landform design and reclamation. Core questions within the program will integrate results to address the broader management decisions which will allow for maintenance of healthy watershed function.

description: This study examines the reasons that airport noise compatibility land use regulations are infrequently implemented in the Northeast United States. Noise compatibility land use regulations are advocated by the Federal Aviation Administration as a solution to the negative externality of airport noise but are rarely enacted by local jurisdictions. To investigate the topic, a mixed-methods approach involving document review and interviews is used to assess the historical circumstances under which some municipalities have adopted this form of regulation while others have not. Five case studies of commercial hub airports in the Northeast serve as examples of implementation scenarios and highlight the challenges inherent in the coordination of airport and municipal development.

Plasmas of Arbitrary Neutrality
Creators: Sarasola Martin, Xabier
Publisher: name: Columbia University
Year: 2011
Subjects: Plasma (Ionized gases)
Physics

description: The physics of partially neutralized plasmas is largely unexplored, partly because of the difficulty of confining such plasmas. Plasmas are confined in a stellarator without the need for a plasma current, and regardless of the degree of neutralization. The Columbia Non-neutral Torus (CNT) is a stellarator dedicated to the study of non-neutral, and partially neutralized plasmas. This thesis describes the first systematic studies of plasmas of arbitrary neutrality. The degree of neutralization of the plasma can be parameterized through the quantity η ≡ |n_e - Z n_i|/|n_e + Z n_i|. In CNT, η can be varied continuously from pure electron (η = 1) to quasi-neutral (η ≈ 0) by adjusting the neutral pressure in the chamber, which controls the volumetric ionization rate. Pure electron plasmas are in macroscopically stable equilibria, and have strong self electric potentials dictated by the emitter filament bias voltage on the magnetic axis. As η decreases, the plasma potential decouples from the emitter, and spontaneous fluctuations begin to appear. Partially neutralized plasmas (10^-3 < η < 10^-1) generally exhibit multi-mode oscillations in CNT. However, when magnetized ions are present, the electron-rich plasma oscillates at a single dominant mode (20 - 100 kHz). As the plasma approaches quasi-neutrality (η < 10^-5), it also reverts to single mode behavior (1 - 20 kHz). A parametric characterization of the single mode fluctuations detected in plasmas of arbitrary neutrality is presented in this thesis along with measurements of the spatial structure of the oscillations. The single mode fluctuations observed for η ≈ 0.01 to 0.8 are identified as an ion resonant instability propagating close to the E × B velocity of the plasma. The experiments also show that these oscillations present a poloidal mode number m = 1, and a toroidal number n = 0, which is identical to the spatial structure of the diocotron instability in pure-toroidal traps, and implies that the ion-driven instability breaks parallel force balance and the conservation of poloidal flux in CNT. The low frequency oscillations detected in the quasi-neutral regime are a global instability convected by the E × B flow of the plasma. In this case, the mode aligns almost perfectly with the field lines, and presents a resonant m = 3 poloidal structure.

description: Magnetic domain walls are topological solitons whose internal structure is set by competing energies which sculpt them. In common ferromagnets, domain walls are known to be of either Bloch or Néel types. Little is established in the case of Mn$_3$Sn, a triangular antiferromagnet with a large room-temperature anomalous Hall effect, where domain nucleation is triggered by a well-defined threshold magnetic field. Here, we show that the domain walls of this system generate an additional contribution to the Hall conductivity tensor and a transverse magnetization. The former is an electric field lying in the same plane with the magnetic field and electric current and therefore a planar Hall effect. We demonstrate that in-plane rotation of spins inside the domain wall would explain both observations and the clockwise or anticlockwise chirality of the walls depends on the history of the field orientation and can be controlled.

description: I discuss the role played by the spin-network basis and recoupling theory (in its graphical tangle-theoretic formulation) and their use for performing explicit calculations in loop quantum gravity. In particular, I show that recoupling theory allows the derivation of explicit expressions for the eingenvalues of the quantum volume operator. An important side result of these computations is the determination of a scalar product with respect to which area and volume operators are symmetric, and the spin network states are orthonormal.

Remarks
This genus includes eight described species, plus several undescribed species. See Fig. 49 for a habitus illustration. They occur in Mexico and Guatemala (also doubtfully recorded from Peru). Whereas the larvae of most Metacyclini are unknown, those of Metacycla are clearly leaf-feeders (Andrews & Gilbert 2005). This suggests a closer relationship of Metacyclini with Galerucini (leaf-feeding larvae) than with Luperini (root-feeding larvae). It is noteworthy that, based on the morphology of Metacycla, Beenen (2013) advocated the synonymy of Metacyclini with Galerucini. Although Cneorane nigripes Allard, 1889 has most recently been classified in Scelida Chapuis, 1875, examination of the male holotype (Museum national d’histoire naturelle, Paris) reveals that this species properly belongs in the genus Metacycla as comb. nov.

description: The thermal Euclidean Green functions for Photons propagating in the Rindler wedge are computed employing an Euclidean approach within any covariant Feynman-like gauge. This is done by generalizing a formula which holds in the Minkowskian case. The coincidence of the found $(\be=2π)$-Green functions and the corresponding Minkowskian vacuum Green functions is discussed in relation to the remaining static gauge ambiguity already found in previous papers. Further generalizations to more complicated manifolds are discussed. Ward identities are verified in the general case.

description: Single crystals of MgB2 with a size up to 1.5x0.9x0.2 mm3 have been grown with a high pressure cubic anvil technique. The crystal growth process is very peculiar and involves an intermediate nitride, namely MgNB9. Single crystals of BN and MgB2 grow simultaneously by a peritectic decomposition of MgNB9. Magnetic measurements in fields of 1-5 Oe show sharp transitions to the superconducting state at 37-38.6 K with width of ~0.5 K. The high quality of the crystals allowed the accurate determination of magnetic, transport and optical properties as well as scanning tunnelling spectroscopy (STS) and decoration studies. Investigations of crystals with torque magnetometry show that Hc2//c is very low (24 kOe at 15 K), while Hc2//ab increases up to 140 kOe at 15 K. The upper critical field anisotropy gamma = Hc2//ab/ Hc2//c was found to be temperature dependent (decreasing from 6 at 15 K to 2.8 at 35 K). The effective anisotropy gamma_eff, as calculated from reversible torque data near Tc, is field dependent (increasing roughly linearly from 2 in zero field to 3.7 in 10 kOe). The temperature and field dependence of the anisotropy can be related to the double gap structure of MgB2 with a large two-dimensional gap and small three-dimensional gap, the latter being rapidly suppressed in a magnetic field. Torque magnetometry investigations show a pronounced peak effect, indicating an order-disorder transition of vortex matter. Decoration experiments and STS visualise a hexagonal vortex lattice. STS spectra evidence two gaps (3 meV/6 meV) with direction dependent weight. Magneto-optic investigations with H//c show a clear signature of the smaller of the two gaps, disappearing in fields higher than Hc2//c.

description: Studies have shown that mergers of massive galaxy clusters produce shocks and turbulence in the intra-cluster medium, the possible event that creates radio relics, as well as the radio halos. Here we present GMRT dual-band (235 and 610~MHz) radio observations of four such clusters from the MAssive Cluster Survey (MACS) catalogue. We report the discovery of a very faint, diffuse, elongated radio source with a projected size of about 0.5~Mpc in cluster MACSJ0152.5-2852. We also confirm the presence of a radio relic-like source (about 0.4~Mpc, previously reported at 325~MHz) in MACSJ0025.4-1222 cluster. Proposed relics in both these clusters are found apparently inside the virial radius instead of their usual peripheral location, while no radio halos are detected. These high-redshift clusters ($z=0.584$ and $0.413$) are among the earliest merging systems detected with cluster radio emissions. In MACSJ1931-2635 cluster, we found a radio mini-halo and an interesting highly bent pair of radio jets. Further, we present here a maiden study of low frequency (GMRT $235\;\&\;610$~MHz) spectral and morphological signatures of a previously known radio cluster MACSJ0014.3-3022 (Abell~2744). This cluster hosts a relatively flat spectrum ($α^{610}_{235}\sim -1.15$), giant ($\sim 1.6$~Mpc each) halo-relic structure and a close-by high-speed ($1769\pm^{148}_{359}$~km~s$^{-1}$) merger-shock ($\mathcal{M}=2.02\pm^{0.17}_{0.41}$) originated from a possible second merger in the cluster.

description: We construct the {\it quasi-stationary} (QS) probability distribution for the Domany-Kinzel stochastic cellular automaton (DKCA), a discrete-time Markov process with an absorbing state. QS distributions are derived at both the one- and two-site levels. We characterize the distribuitions by their mean, and various moment ratios, and analyze the lifetime of the QS state, and the relaxation time to attain this state. Of particular interest are the scaling properties of the QS state along the critical line separating the active and absorbing phases. These exhibit a high degree of similarity to the contact process and the Malthus-Verhulst process (the closest continuous-time analogs of the DKCA), which extends to the scaling form of the QS distribution.

description: We consider downlink (DL) channel estimation for frequency division duplex based massive MIMO systems under the multipath model. Our goal is to provide fast and accurate channel estimation from a small amount of DL training overhead. Prior art tackles this problem using compressive sensing or classic array processing techniques (e.g., ESPRIT and MUSIC). However, these methods have challenges in some scenarios, e.g., when the number of paths is greater than the number of receive antennas. Tensor factorization methods can also be used to handle such challenging cases, but it is hard to solve the associated optimization problems. In this work, we propose an efficient channel estimation framework to circumvent such difficulties. Specifically, a structural training sequence that imposes a tensor structure on the received signal is proposed. We show that with such a training sequence, the parameters of DL MIMO channels can be provably identified even when the number of paths largely exceeds the number of receive antennas---under very small training overhead. Our approach is a judicious combination of Vandermonde tensor algebra and a carefully designed conjugate-invariant training sequence. Unlike existing tensor-based channel estimation methods that involve hard optimization problems, the proposed approach consists of very lightweight algebraic operations, and thus real-time implementation is within reach. Simulation results are carried out to showcase the effectiveness of the proposed methods.

description: We discuss the classicalization of a quantum state induced by an environment in the inflationary stage of the universe. The classicalization is necessary for the homogeneous ground sate to become classical non-homogeneous one accompanied with the statistical fluctuation, which is a plausible candidate for the seeds of structure formation. Using simple models, we show that i) the two classicalization criteria, the classical correlation and quantum decoherence, are simultaneously satisfied by the environment and that ii) the power spectrum of the resultant statistical fluctuation depends upon the detail of the classicalization process. Especially, the result ii) means that, taking account of the classicalization process, the inflationary scenario does not necessarily predict the unique spectrum which is usually believed.

description: The aim of this paper is to discuss new results concerning some kinds of parametric extended entropies and divergences. As a result of our studies for mathematical properties on entropy and divergence, we give new bounds for the Tsallis quasilinear entropy and divergence by applying the Hermite-Hadamard inequality. We also give bounds for biparametrical extended entropies and divergences which have been given in \cite{7}. In addition, we study $(r,q)$-quasilinear entropies and divergences as alternative biparametrical extended entropy and divergence, and then we give bounds for them. Finally we obtain inequalities for an extended Lin's divergence and some characterizations of Fermi-Dirac entropy and Bose-Einstein entropy.

A Bayesian approach to source separation

Publisher: name: arXiv
Year: 2000
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: Source separation is one of the signal processing's main emerging domain. Many techniques such as maximum likelihood (ML), Infomax, cumulant matching, estimating function, etc. have been used to address this difficult problem. Unfortunately, up to now, many of these methods could not account completely for noise on the data, for different number of sources and sensors, for lack of spatial independence and for time correlation of the sources. Recently, the Bayesian approach has been used to push farther these limitations of the conventional methods. This paper proposes a unifying approach to source separation based on the Bayesian estimation. We first show that this approach gives the possibility to explain easily the major known techniques in sources separation as special cases. Then we propose new methods based on maximum a posteriori (MAP) estimation, either to estimate directly the sources, or the mixing matrices or even both.

description: Over the past thirty years, we have seen a rise in sexual self identification and group affiliation based on sexual identity across the world, but particularly in China. Much of the research on this topic has focused on the role capitalism and urbanization has played in producing the circumstances under which tongzhi (gay men) could come together, which has necessarily prioritized processed of transnationalism, class aesthetics and geographic emphasis on coastal areas. This project expands the literature on tongzhi assembling by focusing on the legacy of HIV/AIDS organizations in the province of Yunnan in helping to bring important funding and political opportunity to emerging tongzhi social groups. Through presenting detailed ethnographic data, I argue that the organization’s leaders engage in a form of fragmented authoritarian politics which involves balancing between localized bureaucratic political demands and organizing opportunities of fun for tongzhi men who may lack other spaces and times to meet. In this dissertation I will discuss how activities of play allow these groups to balance between dominant discourses and pragmatic social interactions.

description: All global solutions of arbitrary topology of the most general 1+1 dimensional dilaton gravity models are obtained. We show that for a generic model there are globally smooth solutions on any non-compact 2-surface. The solution space is parametrized explicitly and the geometrical significance of continuous and discrete labels is elucidated. As a corollary we gain insight into the (in general non-trivial) topology of the reduced phase space. The classification covers basically all 2D metrics of Lorentzian signature with a (local) Killing symmetry.

Platelet-Derived Growth Factor Receptor Beta is a Marker and Regulator of Neural Stem Cells in the Adult Ventricular-Subventricular Zone

description: Specific regions within the adult mammalian brain maintain the ability to generate neurons. The largest of these, the ventricular-subventricular zone (V-SVZ), comprises the entire lateral wall of the lateral ventricles. Here, a subset of glial fibrillary acid protein (GFAP)-positive astrocytes (B cells) gives rise to neurons and oligodendrocytes throughout life. This process of neurogenesis involves quiescent B cells becoming proliferative (epidermal growth factor receptor (EGFR)-positive) and giving rise to neuroblasts via transit amplifying precursors. The neuroblasts then migrate through the rostral migratory stream (RMS) to the olfactory bulbs (OBs), where they mature into neurons. Studying the stem cells in the V-SVZ has been hindered by the shortage of molecular markers to selectively target them. Using microarray and qPCR analysis of putative quiescent neural stem cells we determined that they were enriched for PDGFRβ mRNA. We used immunostaining to determine the in vivo identity of PDGFRβ+ cells, and discovered that only GFAP+ cells within the V-SVZ stem cell lineage express PDGFRβ. Moreover, these PDGFRβ+ B cells contact the ventricle at the center of ependymal pinwheel structures and the vast majority of them are EGFR-. Importantly, the V-SVZ/RMS/OBcore axis was highly enriched for PDGFRβ expression compared with other brain regions. Detailed morphological analyses of PDGFRβ+ B cells revealed primary cilia at their apical process in contact with the ventricle and long radial processes contacting blood vessels deep within the V-SVZ, both of which are characteristics of adult neural stem cells. When PDGFRβ+ cells were lineage traced in vivo they formed olfactory bulb neurons.
      Using fluorescence-activated cell sorting (FACS) to purify PDGFRβ+ astrocytes we discovered this receptor is expressed by all adult V-SVZ neural stem cells, including a novel population of EGFR+ PDGFRβ+ cells which correspond to the activated neural stem cells. RNA-sequencing analysis of the purified populations revealed that PDGFRβ+ EGFR+ cells possess a transcriptional profile intermediate between quiescent neural stem cells and actively proliferating GFAP- progenitor cells. Finally, when PDGFRβ is deleted in adult GFAP+ NSCs we observe a decrease in EGFR+ and Dcx+ progenitor cells, together with an increase in quiescent GFAP+ astrocytes. A larger proportion of these mutant cells come in contact with the ventricular lumen, suggesting that PDGFRβ is required for V-SVZ astrocytes to act as stem cells, possibly by mediating interactions with their niche. Taken together, these data identify PDGFRβ as a novel marker for adult V-SVZ neural stem cells that is an important regulator of their stem cell capabilities.
