Some dimensions of a planning problem : residential-agricultural land use conflict in metropolitan rural-urban fringe areas
Creators: name: Yeomans, Martin Gregory
Publisher: name: University of British Columbia
Year: 2010

description: Residential-agricultural land use conflict in the rural-urban fringe of metropolitan areas is commonly mentioned as a planning problem. The initial intent of this research was to correlate types of conflict and local planning responses in order to identify effective approaches to the management of such problems. The anticipated method would have combined theory which addresses the cause and characteristics of residential-agricultural conflict along with data from Vancouver suburbs having substantial agricultural activity and planning departments respected for their professional qualities. However, the investigation showed that the academic literature and the accessible data would not support such research. On the other hand, consultations with local planners and a review of available documentation in the municipalities of Richmond, Delta and Surrey, British Columbia, showed that residential-agricultural land use conflict is treated as a planning problem and is a source of complaints to municipal officials. Three kinds of conclusions resulted from this research. The first and second are appropriate to the underdeveloped state of the academic literature, while the first and third relate to professional practice in the absence of applicable scientific knowledge. The first is a description of the characteristics which are perceived as constituting a planning problem and a governmental response. Secondly, there are recommendations for development of data to support future research. Municipal governments in the three communities have no comprehensive monitoring system or set of cross-referenced records of complaints associated with land use conflicts. Instead, conflicts are received, identified and acted on by a variety of departments in the local government. From the descriptive material a tentative typology is offered to guide data collection and classification. Thirdly, there are suggestions which may be useful to planners who must rely on non-systematic methods to identify conflict situations appropriate for a planning response and to develop that response. The summaries of problems and responses reported are used to develop a tentative critique of present conceptualizations of appropriate planning measures. It is observed that planners have used only a few of the possible responses to rural-urban conflict. In particular, it is clear that for a wide range of conflict types there has been a reliance on land buffers to separate potentially conflicting activities. Alternative and supplementary approaches which may improve the management of typical conflict situations are suggested. These approaches focus on preventing the development of conflict through increasing the mutual understanding of the conflicting parties' points-of-view. Examples include public involvement in problem identification and resolution, as well as programs to facilitate communication between the government, farmers and non-farm residents.

description: In a central nucleus-nucleus collision at high-energies, medium partons kicked by a near-side jet acquire a momentum along the jet direction and subsequently materialize as the observed ridge particles. They carry direct information on the early parton momentum distribution which can be extracted by using the ridge data for central AuAu collisions at \sqrt{s_{NN}}=200 GeV. The extracted parton momentum distribution has a thermal-like transverse momentum distribution but a non-Gaussian, relatively flat rapidity distribution at mid-rapidity with sharp kinematic boundaries at large rapidities that depend on the transverse momentum.

description: Modern embedded and cyber-physical systems require every day more performance, power efficiency and flexibility, to execute several profiles and functionalities targeting the ever growing adaptivity needs and preserving execution efficiency. Such requirements pushed designers towards the adoption of heterogeneous and reconfigurable substrates, which development and management is not that straightforward. Despite acceleration and flexibility are desirable in many domains, the barrier of hardware deployment and operation is still there since specific advanced expertise and skills are needed. Related challenges are effectively tackled by leveraging on automation strategies that in some cases, as in the proposed work, exploit model-based approaches. This paper is focused on the Multi-Dataflow Composer (MDC) tool, that intends to solve issues related to design, optimization and operation of coarse-grain reconfigurable hardware accelerators and their easy adoption in modern heterogeneous substrates. MDC latest features and improvements are introduced in detail and have been assessed on the so far unexplored robotics application field. A multi-profile trajectory generator for a robotic arm is implemented over a Xilinx FPGA board to show in which cases coarse-grain reconfiguration can be applied and which can be the parameters and trade-offs MDC will allow users to play with.

description: Frequently accessed video streams are pre-transcoded into several formats to satisfy the characteristics of all display devices. Storing several video stream formats imposes a high cost on video stream providers using the old classical way. Alternatively, cloud providers offer a high flexibility of using their services and at a low cost relatively. Therefore, video stream companies adopted cloud technology to store their video streams. Generally, having all video streams stored in one type of cloud storage, the cost rises gradually. More importantly, the variation of the access pattern to frequently accessed video streams impacts negatively the storage cost and increases it significantly. To optimize storage usage and lower its cost, we propose a method that manages the cloud hierarchy storage. Particularly, we develop an algorithm that operates on parts of different videos that are frequently accessed and stores them in their suitable storage type cloud. Experiments came up with promising results on reducing the cost of using cloud storage by 18.75 %.

description: The hermitian Wilson kernel used in the construction of the domain-wall and overlap Dirac operators has exceptionally small eigenvalues that make it expensive to reach high-quality chiral symmetry for domain-wall fermions, or high precision in the case of the overlap operator. An efficient way of suppressing such eigenmodes consists of including a positive power of the determinant of the Wilson kernel in the Boltzmann weight, but doing this also suppresses tunneling between topological sectors. Here we propose a modification of the Hybrid Monte-Carlo algorithm which aims to restore tunneling between topological sectors by excluding the lowest eigenmodes of the Wilson kernel from the molecular-dynamics evolution, and correcting for this at the accept/reject step. We discuss the implications of this modification for the acceptance rate.

description: Building upon recent developments of force-based estimators with a reduced variance for the computation of densities, radial distribution functions or local transport properties from molecular simulations, we show that the variance can be further reduced by considering optimal linear combinations of such estimators. This control variates approach, well known in Statistics and already used in other branches of computational Physics, has been comparatively much less exploited in molecular simulations. We illustrate this idea on the radial distribution function and the one-dimensional density of a bulk and confined Lennard-Jones fluid, where the optimal combination of estimators is determined for each distance or position, respectively. In addition to reducing the variance everywhere at virtually no additional cost, this approach cures an artefact of the initial force-based estimators, namely small but non-zero values of the quantities in regions where they should vanish. Beyond the examples considered here, the present work highlights more generally the underexplored potential of control variates to estimate observables from molecular simulations.

Deep Westerbork observations of Abell 2256 at 350 MHz
Creators: name: Brentjens, M. A.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Deep polarimetric Westerbork observations of the galaxy cluster Abell 2256 are presented, covering a frequency range of 325-377 MHz. The central halo source has a diameter of the order of 1.2 Mpc (18'), which is somewhat larger than at 1.4 GHz. With alpha=-1.61+/-0.04, the halo spectrum between 1.4 GHz and 22.25 MHz is less steep than previously thought. The centre of the ultra steep spectrum source in the eastern part of the cluster exhibits a spectral break near 400 MHz. It is estimated to be at least 51 million years old, but possibly older than 125 million years. A final measurement requires observations in the 10-150 MHz range. It remains uncertain whether the source is a radio tail of Fabricant galaxy 122, situated in the northeastern tip of the source. Faraday rotation measure synthesis revealed no polarized flux at all in the cluster. The polarization fraction of the brightest parts of the relic area is less than 1%. The RM-synthesis nevertheless revealed 9 polarized sources in the field enabling an accurate measurement of the Galactic Faraday rotation (-33+/-2 rad m^{-2} in front of the relic). Based on its depolarization on longer wavelengths, the line-of-sight magnetic field in relic filament G is estimated to be between 0.02 and 2 uG. A value of 0.2 uG appears most reasonable given the currently available data.

description: Evaluation of relativistic molecular integrals over exponential-type spinor orbitals require using the relativistic auxiliary functions in prolate spheroidal coordinates. They have derived recently by the author [Physical Review E 91, 023303 (2015)]. They are used in solution of the molecular Dirac equation for electrons moving around Coulomb potential. A series of papers on a method for fully analytical evaluation of relativistic auxiliary functions in following, published [2, 3, 4]. From the computational physics point of view, these works also demonstrate how to deal with the integrals involve product of power functions with non-integer exponents and incomplete gamma functions. The computer program package to calculate these auxiliary functions in high accuracy is presented. It is designed in Julia programming language. It is capable of yielding highly accurate results for molecular integrals over a wide range of orbital parameters and quantum numbers. Additionally, the program package provides numerous tools such as efficient calculation for the angular momentum coefficients arising in the product of two normalized associated Legendre functions centered on different atomic positions, the rotation angular functions used for both complex and real spherical harmonics. Sample calculations are performed for two-center one-electron integrals over non-integer Slater-type orbitals. The results prove that the package is robust.

description: We demonstrate the electrical detection of magnon-magnon hybrid dynamics in yttrium iron garnet/permalloy (YIG/Py) thin film bilayer devices. Direct microwave current injection through the conductive Py layer excites the hybrid dynamics consisting of the uniform mode of Py and the first standing spin wave ($n=1$) mode of YIG, which are coupled via interfacial exchange. Both the two hybrid modes, with Py or YIG dominated excitations, can be detected via the spin rectification signals from the conductive Py layer, providing phase resolution of the coupled dynamics. The phase characterization is also applied to a nonlocally excited Py device, revealing the additional phase shift due to the perpendicular Oersted field. Our results provide a device platform for exploring hybrid magnonic dynamics and probing their phases, which are crucial for implementing coherent information processing with magnon excitations

description: Abstract

Farming activity is one of efforts to increase economy level of the farmers. One of farming activities is ability to utilize farming land. Pagerwojo District of Tulungagung Regency is one of villages that is potential to be used as farming land. Current condition has been able to develop an organic-based farming, which offers great benefits for farmers and the society. Implementation of such farming is followed by social capital to support and utilize the resources in the environment. This research studied problems that focused on the impact of social capital on adoption of the organic farming innovation in Pagerwojo district in order to increase economy level of the farmers. Objectives of the research were: 1) Identify parameter of the social capital (trust, norm, and network) in Pagerwojo District; 2) Identify parameter on adoption of the organic farming innovation in Pagerwojo District, and 3) Analyze the impact of social capital on adoption of the organic farming innovation in Pagerwojo District. Method of the research was combining the descriptive and explanatory research. The location was selected in accordance with case study in Pagerwojo District of Tulungagung Regency. Data of the research was primary data that was collected through interview and respondents were selected using Snowball sampling technique. The analysis method used Likert’s scale, which will be conversed using factor analysis with dependent variable such as adoption of innovation, and independent variables that include network, trust, and norm. Therefore, it indicated what is the extent of social capital affects the adoption of organic farming innovation in Pagerwojo District, Tulungagung Regency.

description: We study the Josephson current through a ferromagnetic trilayer, both in the diffusive and clean limits. For colinear (parallel or antiparallel) magnetizations in the layers, the Josephson current is small due to short range proximity effect in superconductor/ferromagnet structures. For non colinear magnetizations, we determine the conditions for the Josephson current to be dominated by another contribution originating from long range triplet proximity effect.

description: A mechanism of Mott transitions in a Bose Hubbard model on a square lattice is studied, using a variational Monte Carlo method. Besides an onsite correlation factor, we introduce a four-body doublon-holon factor into the trial state, which considerably improves the variational energy and can appropriately describe a superfluid-insulator transition. Its essense consists in binding (and unbinding) of a doublon to a holon in a finite short range, identical with the cases of fermions. The features of this transition are qualitatively different from those of Brinkman-Rice-type transitions.

Statistical properties of the localization measure of chaotic eigenstates and the spectral statistics in a mixed-type billiard

description: We study the quantum localization in the chaotic eigenstates of a billiard with mixed-type phase space, after separating the regular and chaotic eigenstates, in the regime of slightly distorted circle billiard where the classical transport time in the momentum space is still large enough, although the diffusion is not normal. In quantum systems with discrete energy spectrum the Heisenberg time $t_H =2π\hbar/ΔE$, where $ΔE$ is the mean level spacing, is an important time scale.The classical transport time scale $t_T$ in relation to the Heisenberg time scale $t_H$ (their ratio is the parameter $α=t_H/t_T$) determines the degree of localization of the chaotic eigenstates, whose measure $A$ is based on the information entropy. We show that $A$ is linearly related to normalized inverse participation ratio. The localization of chaotic eigenstates is reflected also in the fractional power-law repulsion between the nearest energy levels in the sense that the probability density to find successive levels on a distance $S$ goes like $\propto S^β$ for small $S$, where $0\leqβ\leq1$, and $β=1$ corresponds to completely extended states. We show that the level repulsion exponent $β$ is empirically a rational function of $α$, and the mean $\langle A \rangle$ as a function of $α$ is also well approximated by a rational function. In both cases there is some scattering of the empirical data around the mean curve, which is due to the fact that $A$ actually has a distribution, typically with quite complex structure, but in the limit $α\rightarrow \infty$ well described by the beta distribution. Like in other systems, $β$ goes from $0$ to $1$ when $α$ goes from $0$ to $\infty$. $β$ is a function of $\langle A \rangle$, similar to the quantum kicked rotator and the stadium billiard.

description: We provide a novel mechanism that resolves the Big Bang Singularity present in FRW space-times without the need for ghost fields. Building on the fact that a four-fermion interaction arises in General Relativity when fermions are covariantly coupled, we show that at early times the decrease in scale factor enhances the correlation between pairs of fermions. This enhancement leads to a BCS-like condensation of the fermions and opens a gap dynamically driving the Hubble parameter $H$ to zero and results in a non-singular bounce, at least in some special cases.

description: Viscoelastic flows through porous media become unstable and chaotic beyond critical flow conditions, impacting industrial and biological processes. Recently, Walkama \textit{et al.} [Phys. Rev. Lett. \textbf{124}, 164501 (2020)] have shown that geometric disorder greatly suppresses such chaotic dynamics. We demonstrate experimentally that geometric disorder \textit{per se} is not the reason for this suppression, and that disorder can also promote choatic fluctuations, given a slightly modified initial condition. The results are explained by the effect of disorder on the occurrence of stagnation points exposed to the flow field, which depends on the initially ordered geometric configuration.

There arises an operator ordering problem when the target space is curved. We have to fix the ordering in quantum operator properly to obtain the correct supersymmetry algebra. We demonstrate that the super-Poincaré algebra fixes the correct operator ordering. We obtain a supercurrent with correct operator ordering and a central extension of supersymmetry algebra.

description: We demonstrate a sequence of two quantum teleportations of optical coherent states, combining two high-fidelity teleporters for continuous variables. In our experiment, the individual teleportation fidelities are evaluated as F_1 = 0.70 \pm 0.02 and F_2 = 0.75 \pm 0.02, while the fidelity between the input and the sequentially teleported states is determined as F^{(2)} = 0.57 \pm 0.02. This still exceeds the optimal fidelity of one half for classical teleportation of arbitrary coherent states and almost attains the value of the first (unsequential) quantum teleportation experiment with optical coherent states.

description: We interpret the phase structure of hadronic matter in terms of the basic dynamical and geometrical features of hadrons. Increasing the density of constituents of finite spatial extension, by increasing the temperature T or the baryochemical potential mu, eventually "fills the box" and eliminates the physical vacuum. We determine the corresponding transition as function of T and mu through percolation theory. At low baryon density, this means a fusion of overlapping mesonic bags to one large bag, while at high baryon density, hard core repulsion restricts the spatial mobility of baryons. As a consequence, there are two distinct limiting regimes for hadronic matter. We compare our results to those from effective chiral model studies.

description: We show that the gauge hierarchy problem can be solved in the framework of scalar-tensor theories of gravity very much in the same way as it is solved in the Randall-Sundrum scenario. Our solution involves a fine-tuning of the gravitational sector. However our mechanism does not require the introduction of extra-dimensions or new physics strongly coupled to the standard model in the low energy regime. We do introduce a new scalar field which is however coupled only gravitationally to regular matter. The physical reason for the splitting between the weak scale and the Planck scale is a violation of the Einstein's equivalence principle.

description: In the first part of this study, a non-ferric method for selective elimination of β-lactoglobulin from cheese whey was investigated. A new method was developed based on hexametaphosphate treatment of cheese whey. When Cheddar cheese whey was treated under the optimized conditions, i.e., 1.33 mg/mL sodium hexametaphosphate at 22°C and pH 4.07 for 1 hr, more than 80% of β-lactoglobulin was removed by precipitation. Almost all of the immunoglobulins and the major portion of α-lactalbumin were retained in the supernatant as indicated by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and immunochemical assays. By dialysis against distilled water 72.2% of the phosphorus was removed from the supernatant. In the second and the third part of the thesis, chromatographic methods were used for isolation of immunoglobulins and lactoferrin from whey proteins. By using gel filtration on Sephacryl S-300, 99, 83.3 and 92.1% biologically active immunoglobulin G were obtained for colostral whey, acid and Cheddar cheese whey, respectively. Lactoferrin, selectively adsorbed to the heparin-attached Sepharose, was eluted with 5 mM Veronal-HC1 containing 0.5M NaC1, at pH 7.2. 1,4-Butanediol diglycidyl ether-iminodiacetic acid on Sepharose 6B, or so-called metal chelate-interaction chromatography (MCIC), was loaded with copper ion and used for the same purpose. Of the two peaks obtained, the first yellowish peak was rich in lactoferrin, while the second peak was rich in immunoglobulins. Some of the physical and chemical properties of the proteins in these peaks, including immunochemical properties, isoelectric points, binding to bacterial lipopolysaccharides, and the mechanism of protein-metal interaction via histidine modification, and the capacity of the method were studied. The possibility of isolating immunoglobulins and lactoferrin from electrodialyzed whey was also investigated. In the fourth, fifth and sixth parts of the thesis, the method developed for isolation of immunoglobulins and lactoferrin from whey protein was applied to isolate these biologically important proteins directly from skimmilk, blood and egg white. The casein in skimmilk was found to compete with immunoglobulins for binding to copper ion in MCIC column when skimmilk was loaded in presence of 0.05 M Tris-acetate buffer containing 0.5 M NaC1, pH 8.2; however, this problem was solved by changing the equilibrating buffer to 0.02 M phosphate buffer containing 0.5 M NaC1, pH 7.0. When blood was directly applied to MCIC column, the yield of biologically active IgG was more than 95%. Ovotransferrin, strongly adsorbed to the MCIC column, was eluted with two-step elution protocols which suggests it exists in two forms. The histidine residues in immunoglobulins, caseins, transferrin and ovotransferrin were found to be involved in the mechanism of the interaction with the MCIC column.

description: During the study of a large set of late-type stellar X-ray sources, we discovered a large fraction of multiple systems. In this paper we investigate the orbital elements and kinematic properties of three new spectroscopic triple systems as well as spectral types and astrophysical parameters (T_eff, log g, vsin i, log N(Li)) of their components. We conducted follow-up optical observations, both photometric and spectroscopic at high resolution, of these systems. We used a synthetic approach and the cross-correlation method to derive most of the stellar parameters. We estimated reliable radial velocities and deduced the orbital elements of the inner binaries. The comparison of the observed spectra with synthetic composite ones, obtained as the weighted sum of three spectra of non-active reference stars, allowed us to determine the stellar parameters for each component of these systems. We found all are only composed of main sequence stars. These three systems are certainly stable hierarchical triples composed of short-period inner binaries plus a tertiary component in a long-period orbit. From their kinematics and/or Lithium content, these systems result to be fairly young.

description: We introduce and implement an interferometric technique based on chirped femtosecond laser pulses and nonlinear optics. The interference manifests as a high-visibility (> 85%) phase-insensitive dip in the intensity of an optical beam when the two interferometer arms are equal to within the coherence length of the light. This signature is unique in classical interferometry, but is a direct analogue to Hong-Ou-Mandel quantum interference. Our technique exhibits all the metrological advantages of the quantum interferometer, but with signals at least 10^7 times greater. In particular we demonstrate enhanced resolution, robustness against loss, and automatic dispersion cancellation. Our interferometer offers significant advantages over previous technologies, both quantum and classical, in precision time delay measurements and biomedical imaging.

A new test of the light dark matter hypothesis

description: Detection of a surprisingly high flux of positron annihilation radiation from the inner galaxy has motivated the proposal that dark matter is made of weakly interacting light particles (possibly as light as the electron). This scenario is extremely hard to test in current high energy physics experiments. Here, however, we demonstrate that the current value of the electron anomalous magnetic moment already has the required precision to unambiguously test the light dark matter hypothesis. If confirmed, the implications for astrophysics are far-reaching.

description: The first-principles simulation of the electronic structure of organic semiconductors in solution poses a number of challenges that are not trivial to address simultaneously. In this work, we investigate the effects and the mutual interplay of solvation, alkylization, and doping on the structural, electronic, and optical properties of sexithiophene, a representative organic semiconductor molecule. To this end, we employ (time-dependent) density functional theory in conjunction with the polarizable-continuum model. We find that the torsion between adjacent monomer units plays a key role, as it strongly influences the electronic structure of the molecule, including energy gap, ionization potential, and band widths. Alkylization promotes delocalization of the molecular orbitals up to the first methyl unit, regardless of the chain length, leading to an overall shift of the energy levels. The alterations in the electronic structure are reflected in the optical absorption, which is additionally affected by dynamical solute-solvent interactions. Taking all these effects into account, solvents decrease the optical gap by an amount that depends on its polarity, and concomitantly increase the oscillator strength of the first excitation. The interaction with a dopant molecule promotes planarization. In such scenario, solvation and alkylization enhance charge transfer both in the ground state and in the excited state.

description: A mesoscopic multi-component lattice Boltzmann model with short-range repulsion between different species and short/mid-ranged attractive/repulsive interactions between like-molecules is introduced. The interplay between these composite interactions gives rise to a rich configurational dynamics of the density field, exhibiting many features of disordered liquid dispersions (micro-emulsions) and soft-glassy materials, such as long-time relaxation due to caging effects, anomalous enhanced viscosity, ageing effects under moderate shear and flow above a critical shear rate.

description: C*-endomorphisms arising from superselection structures with non-trivial centre define a 'rank' and a 'first Chern class'. Crossed products by such endomorphisms involve the Cuntz-Pimsner algebra of a vector bundle having the above-mentioned rank and first Chern class, and can be used to construct a duality for abstract (nonsymmetric) tensor categories vs. group bundles acting on (nonsymmetric) Hilbert bimodules. Existence and unicity of the dual object (i.e., the 'gauge' group bundle) are not ensured: we give a description of this phenomenon in terms of a certain moduli space associated with the given endomorphism. The above-mentioned Hilbert bimodules are noncommutative analogues of gauge-equivariant vector bundles in the sense of Nistor-Troitsky.

description: The formation of a novel spin-polarized 2D electron gas at the LaMnO$_3$ monolayer embedded in SrMnO$_3$ is predicted from the first-principles density-functional calculations. The La (d) electrons become confined in the direction normal to the interface in the potential well of the La layer, serving as a positively-charged layer of electron donors. These electrons mediate a ferromagnetic alignment of the Mn t$_{2g}$ spins near the interface via the Anderson-Hasegawa double exchange and become, in turn, spin-polarized due to the internal magnetic fields of the Mn moments.

description: The $γ$ Cephei system is one of the most closely bound binary planet hosts known to date. The companion ($γ$ Cep B) to the planet-hosting star ($γ$ Cep A) should have truncated any protoplanetary disk around $γ$ Cep A, possibly limiting planet formation in the disk. We explore this problem by calculating the truncation radii of protoplanetary disk models around $γ$ Cep A to determine whether or not there is sufficient material remaining in the disk to form a planet. We vary the accretion rate and viscosity parameter of the disk models to cover a range of reasonable possibilities for the disks properties and determine that for accretion rates of $\geq 10^{-7}$ M$_{\sun}$/yr and low viscosity parameter, sufficient material in gas and solids exist for planet formation via core accretion to be possible. Disk instability is less favored, as this can only occur in the most massive disk model with an extremely high accretion rate.
