description: Intensification of agricultural practices is occurring in Canterbury. Dairy farm conversions continue with land use increasing 132% since 1995. Current concerns emanate predominantly from issues of water quantity and quality, in particular the degradation of lowland streams. These and other costs are not transmitted through markets for dairy products, these negative externalities represent allocation and equity concerns for regional policy makers. This study canvassed regional policy administrators, assembled available valuation studies and performed rudimentary calculations based on reviewed New Zealand literature to form an estimate of the external costs of dairy farming in Canterbury. External costs are estimated at $28.7 to $45 million annually. Using 146,000 hectares of dairy in Canterbury, external costs per hectare is calculated at $196.59 to $308.23. Damage to air resources from CO2 equivalent emissions is the largest category and is estimated to be $24.2 to $40.4 million per year

description: Quantum correlations in observables of multiple systems not only are of fundamental interest, but also play a key role in quantum information processing. As a signature of these correlations, the violation of Bell inequalities has not been demonstrated with multipartite hybrid entanglement involving both continuous and discrete variables. Here we create a five-partite entangled state with three superconducting transmon qubits and two photonic qubits, each encoded in the mesoscopic field of a microwave cavity. We reveal the quantum correlations among these distinct elements by joint Wigner tomography of the two cavity fields conditional on the detection of the qubits and by test of a five-partite Bell inequality. The measured Bell signal is $8.381\pm0.038$, surpassing the bound of 8 for a four-partite entanglement imposed by quantum correlations by 10 standard deviations, demonstrating the genuine five-partite entanglement in a hybrid quantum system.

Modelling and characterization of Steller sea lion haulouts and rookeries using oceanographic and shoreline type data
Creators: name: Ban, Stephen S.
Publisher: name: University of British Columbia
Year: 2009

description: Steller sea lions range across the Pacific rim from Southern California in the east to northern Japan in the west, where they have continuously occupied terrestrial resting sites (haulouts) and breeding sites (rookeries) for hundreds of years, if not longer. Why they choose (and stay) at these locations, and what their preferred habitat is, remains unknown. Thus, two aspects of the Steller sea lion's habitat usage were examined—the oceanographic and the terrestrial. For the oceanographic aspect, spatial models were constructed to determine which oceanographic factors are associated with haulouts and rookeries, and how conditions near sites might differ from conditions elsewhere. The two modelling techniques employed (logistic regression and supervised classification) were evaluated using the kappa statistic (Kn o), and receiver-operating characteristic (ROC) plots. Supervised classification was found to produce better-fitting models than logistic regression. In general, Steller sea lions showed preferences for sites associated with waters that were relatively shallow, well-mixed, had higher average tidal speeds and less-steep bottom slopes. Conditions within 1 nautical mile of land were better predictors of haulout and rookery locations than were conditions within 10, 20, and 50 nautical miles. No consistent differences were found in the physical characteristics of waters surrounding sites in the eastern and western populations of Steller sea lions, or between haulouts and rookeries. Regarding the terrestrial aspect of their habitat, anecdotal accounts describe Steller sea lions as predominantly occupying exposed, rocky shorelines, but this habitat preference has never been quantified. Locations of haulouts and rookeries were compared against a coastline type database to identify the shoreline preferences of Steller sea lions and to look for other spatial trends in site characteristics. Haulouts and rookeries were preferentially located on exposed rocky shorelines and wave-cut platforms. No relationship was found between either latitude or longitude of a site and its average non-pup count. The results indicate that there are differences in both the oceanographic and terrestrial characteristics of sites used by Steller sea lions versus areas of coastline where they are not found. The models could be used to predict changes in habitat use given changing physical conditions, and could be applied to any central-place forager.

description: The angular distributions of the baryon-antibaryon low-mass enhancements seen in the charmless three-body baryonic B decays B+ -> p pbar K+, B0 -> p pbar Ks, and B0 -> p Lambdabar pi- are reported. A quark fragmentation interpretation is supported, while the gluonic resonance picture is disfavored. Searches for the Theta+ and Theta++ pentaquarks in the relevant decay modes and possible glueball states G with 2.2 GeV/c2 < M-ppbar < 2.4 GeV/c2 in the ppbar systems give null results. We set upper limits on the products of branching fractions, B(B0 -> Theta+ p)\times B(Theta+ -> p Ks) < 2.3 \times 10^{-7}, B(B+ -> Theta++ pbar) \times B(Theta++ -> p K+) < 9.1 \times 10^{-8}, and B(B+ -> G K+) \times B(G -> p pbar) < 4.1 \times 10^{-7} at the 90% confidence level. The analysis is based on a 140 fb^{-1} data sample recorded on the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider.

description: Este trabalho aborda aspectos teóricos e ações dos movimentos que atuam no campo e que se propõem ocupar espaço e/ou resistir aos padrões de acumulação capitalista no Brasil. Em especial, são focados os movimentos e entidades que reivindicam inserção na agricultura e a reprodução do seu modo de vida no meio rural. Busca-se compreender a fundamentação teórica e a motivação da ação coletiva que relaciona as aspirações dos movimentos sociais de base com o discurso do uso sustentável da terra. A pesquisa realizada teve como base revisão bibliográfica e relatórios de governos, ONG’s, movimentos sociais e pesquisadores, bem como entrevistas com representantes de movimentos sociais. Partiu-se do pressuposto de que interações pró-ativas de enfrentamento ao status quo das relações de produção no campo, tenham como motivação a alteração de uma realidade de contradições ou mesmo de insustentabilidade social, econômica ou ambiental. Desenvolve-se a tese de que os diversos atores sociais necessitam organização de base estabelecida ou em processo dinâmico nesse sentido. São destacados os atores sociais no campo brasileiro e suas demandas por terra em função das perspectivas do uso de grandes áreas para a produção de agrocommodities para os biocombustíveis.

description: The following paper presents two simulation strategies for compressible two-phase or multicomponent flows. One is a full non-equilibrium model in which the pressure and velocity are driven towards the equilibrium at interfaces by numerical relaxation processes, the second is a four-equation model that assumes stiff mechanical and thermal equilibrium between phases or components. In both approaches, the thermodynamic behaviour of each fluid is modelled independently according to the stiffened-gas equations of state. The presented methods are used to simulate the de-pressurization of a pipe containing pure CO$_2$ liquid and vapour under the one-dimensional approximation.

description: Motivated by sensor networks and other distributed settings, several models for distributed learning are presented. The models differ from classical works in statistical pattern recognition by allocating observations of an independent and identically distributed (i.i.d.) sampling process amongst members of a network of simple learning agents. The agents are limited in their ability to communicate to a central fusion center and thus, the amount of information available for use in classification or regression is constrained. For several basic communication models in both the binary classification and regression frameworks, we question the existence of agent decision rules and fusion rules that result in a universally consistent ensemble. The answers to this question present new issues to consider with regard to universal consistency. Insofar as these models present a useful picture of distributed scenarios, this paper addresses the issue of whether or not the guarantees provided by Stone's Theorem in centralized environments hold in distributed settings.

description: Designed for commercial decentralized applications (DApps), EOSIO is a Delegated Proof-of-Stake (DPoS) based blockchain system. It has overcome some shortages of the traditional blockchain systems like Bitcoin and Ethereum with its outstanding features (e.g., free for usage, high throughput and eco-friendly), and thus becomes one of the mainstream blockchain systems. Though there exist billions of transactions in EOSIO, the ecosystem of EOSIO is still relatively unexplored. To fill this gap, we conduct a systematic graph analysis on the early EOSIO by investigating its four major activities, namely account creation, account vote, money transfer and contract authorization. We obtain some novel observations via graph metric analysis, and our results reveal some abnormal phenomenons like voting gangs and sham transactions.

description: Standard epidemiological models for COVID-19 employ variants of compartment (SIR) models at local scales, implicitly assuming spatially uniform local mixing. Here, we examine the effect of employing more geographically detailed diffusion models based on known spatial features of interpersonal networks, most particularly the presence of a long-tailed but monotone decline in the probability of interaction with distance, on disease diffusion. Based on simulations of unrestricted COVID-19 diffusion in 19 U.S cities, we conclude that heterogeneity in population distribution can have large impacts on local pandemic timing and severity, even when aggregate behavior at larger scales mirrors a classic SIR-like pattern. Impacts observed include severe local outbreaks with long lag time relative to the aggregate infection curve, and the presence of numerous areas whose disease trajectories correlate poorly with those of neighboring areas. A simple catchment model for hospital demand illustrates potential implications for health care utilization, with substantial disparities in the timing and extremity of impacts even without distancing interventions. Likewise, analysis of social exposure to others who are morbid or deceased shows considerable variation in how the epidemic can appear to individuals on the ground, potentially affecting risk assessment and compliance with mitigation measures. These results demonstrate the potential for spatial network structure to generate highly non-uniform diffusion behavior even at the scale of cities, and suggest the importance of incorporating such structure when designing models to inform healthcare planning, predict community outcomes, or identify potential disparities.

description: Using SU(3) lattice QCD, we perform the first systematic study for the ground-state three-quark (3Q) potential $V_{\rm 3Q}^{\rm g.s.}$ and the 1st excited-state 3Q potential $V_{\rm 3Q}^{\rm e.s.}$, {\it i.e.}, the energies of the ground state and the 1st excited state of the gluon field in the presence of the static three quarks. From the accurate and thorough calculation for more than 300 different patterns of 3Q systems, the static ground-state 3Q potential $V_{\rm 3Q}^{\rm g.s.}$ is found to be well described by the Coulomb plus Y-type linear potential, {\it i.e.}, Y-Ansatz, within 1%-level deviation. As a clear evidence for Y-Ansatz, Y-type flux-tube formation is actually observed on the lattice in maximally-Abelian projected QCD. For more than 100 patterns of 3Q systems, we calculate the 1st excited-state 3Q potential $V_{\rm 3Q}^{\rm e.s.}$ in quenched lattice QCD, and find the gluonic excitation energy $ΔE_{\rm 3Q} \equiv V_{\rm 3Q}^{\rm e.s.}-V_{\rm 3Q}^{\rm g.s.}$ to be about 1 GeV. This large gluonic-excitation energy is conjectured to ensure the success of the quark model for the low-lying hadrons even without gluonic excitations.

description: We study a dark energy scenario in the presence of a tachyon field $ϕ$ with potential $V(ϕ)$ and a barotropic perfect fluid. The cosmological dynamics crucially depends on the asymptotic behavior of the quantity $λ=-M_pV_ϕ/V^{3/2}$. If $λ$ is a constant, which corresponds to an inverse square potential $V(ϕ) \propto ϕ^{-2}$, there exists one stable critical point that gives an acceleration of the universe at late times. When $λ\to 0$ asymptotically, we can have a viable dark energy scenario in which the system approaches an ``instantaneous'' critical point that dynamically changes with $λ$. If $|λ|$ approaches infinity asymptotically, the universe does not exhibit an acceleration at late times. In this case, however, we find an interesting possibility that a transient acceleration occurs in a regime where $|λ|$ is smaller than of order unity.

description: The broad changes in the soil nematodes, Acari and Collembola of a beech forest, a felled beech grove and a beech grove reforested with larch have been exanimate. The woods are located in Navarra (North of Spain). 476taxa were identified, and their distribution seems to show a disruptive effect of the introduction of larch which may be larger than that of the felling or the seasonal component. The faunistic diversity is larger in the natural forest, despite being a phenologically more homogeneous biotope.
Influences of mountain pine beetle (Dendroctonus ponderosea), fire, and ungulate browsing on forest stand structure in the southern Canadian Rocky Mountains
Creators: name: Dordel, Julia
Publisher: name: University of British Columbia

description: Forests in the montane and lower subalpine ecoregions of the southern Canadian Rocky Mountains may have been more open and structurally diverse at the beginning of the 20th century than today. Today, mature Pinus contorta var. latifolia Dougl. (lodgepole pine) causing mountain pine beetle (MPB, Dendroctonus ponderosae) infestations, infrequent high severity fires, and herbivory appear to have increased in Banff and Kootenay National Parks. Based on a review of the literature it was hypothesised that 1. MPB infestations increase forest stand structural diversity; 2. Browsing intensity decreases with increasing amounts of coarse woody debris; and 3. Disturbances such as MPB infestation and low severity fire lead to decreased MPB stand susceptibility. Stand structure parameters were investigated in mesic montane and lower subalpine stands 15, 25, and 65 years after MPB outbreaks. Parameters measured were tree density, diameter, height class, species, and age distributions as well as coarse woody debris mass. Also, influences of fire frequency, time since fire and fire severity on the current stand structure were analysed. A MPB susceptibility index was calculated for stands with different MPB and fire disturbance histories. The Shannon-Wiener index indicated higher stand structural diversity on plots 15 years but not 25 and 65 years after MPB infestations. Influences of fire on stand structure were limited to increasing tree density with increasing time since the stand initiation fire, and higher proportions of understory vegetation at lower fire severities. Also, there was an indication that high amounts of coarse woody debris resulted in reduced browsing intensity. Finally, the MPB susceptibility index was significantly lower on stands with previous MPB infestations. The MPB susceptibility index also tended to be lower with increasing number of fires. Consequently, none of the above hypothesis could be rejected. Low intensity fires and a reduction of herbivory might be crucial to promote other early successional species such as Populus tremuloides (trembling aspen). Management strategies allowing for MPB and fire disturbances would benefit the ecosystems in the study area.

Using the H-theorem, within the framework of the two-parameter Lorentz-like gauge (so called v-gauge), we show that two kinds of magnetic vector potentials exist: one of them (solenoidal) can act exclusively with the velocity of light c and the other one (irrotational) with an arbitrary finite velocity $v$ (including a velocity more than c . We show also that the irrotational component of the electric field has a physical meaning and can propagate exclusively instantaneously.

description: UbiComp has been envisioned to bring about a future dominated by calm computing technologies making our everyday lives ever more convenient. Yet the same vision has also attracted criticism for encouraging a solitary and passive lifestyle. The aim of this paper is to explore and elaborate these tensions further by examining the human values surrounding future domestic UbiComp solutions. Drawing on envisioning and contravisioning, we probe members of the public (N=28) through the presentation and focus group discussion of two contrasting animated video scenarios, where one is inspired by "calm" and the other by "engaging" visions of future UbiComp technology. By analysing the reasoning of our participants, we identify and elaborate a number of relevant values involved in balancing the two perspectives. In conclusion, we articulate practically applicable takeaways in the form of a set of key design questions and challenges.

Abelianization of QCD in the Maximally Abelian Gauge and the Nambu-'t Hooft Picture for Color Confinement

Subjects: subject: High Energy Physics - Lattice (hep-lat)

description: We study the Nambu-'t Hooft picture for color confinement in terms of the abelianization of QCD and monopole condensation in the maximally abelian (MA) gauge. In the MA gauge in the Euclidean metric, the off-diagonal gluon amplitude is strongly suppressed, and then the off-diagonal gluon phase shows strong randomness, which leads to rapid reduction of the off-diagonal gluon correlation. In SU(2) and SU(3) lattice QCD in the MA gauge with the abelian Landau gauge, the Euclidean gluon propagator indicates a large effective mass of the off-diagonal gluon as $M_{\rm off} \simeq 1 {\rm GeV}$ in the intermediate distance as $0.2{\rm fm} \le r \le 0.8{\rm fm}$. Due to the infrared inactiveness of off-diagonal gluons, infrared QCD is well abelianized like nonabelian Higgs theories in the MA gauge. We investigate the inter-monopole potential and the dual gluon field $B_μ$ in the MA gauge, and find longitudinal magnetic screening with $m_B \simeq$ 0.5 GeV in the infrared region, which indicates the dual Higgs mechanism by monopole condensation. We define the ``gluonic Higgs scalar field'' providing the MA projection, and find the correspondence between its hedgehog singularity and the monopole location in lattice QCD.

The understanding of the meaning of social and economic development involves the mechanisms of distribution of the wealth generated in this context, the viability of the concept of sustainability will lead to changes in social behaviour (collective) and individual. The discussion about the behavior and planned and rational use of natural resources is central to the perpetuation of these resources for future generations.

Impact of juvenile wood on the drying characteristics of Pacific Coast Hemlock structural timber
Creators: name: Bradic, Slobodan
Publisher: name: University of British Columbia

description: Large volumes o f relatively small-diameter logs are generated from sustainable sources such as the Pacific Coast Hemlock second-growth forests. The percentage of juvenile wood in this kind of material is higher compared to limited old growth wood supplies. The present scientific knowledge is often limited to individual properties of juvenile wood without including interactions with other drying factors. For that reason, this investigation evaluates the drying quality of the mix of 105 mm square timbers from second-growth western hemlock (Tsuga heterophylla) and amabilis fir (Abies amabilis), commercially known as Pacific Coast Hemlock baby-squares, using two different concepts of interactions. First, the evaluation is based on the influence of juvenile wood presence shown with a pith location at their end-surface and drying target moisture content, while in the second concept the cutting season is added as the third controlled factor. Timber specimens were classified into four groups depending on the presence and location of the tree pith. A total of 640 specimens were dried in a laboratory conventional (heat-and-vent) kiln in four drying runs to 15% and 20% target moisture contents, with one charge of specimens from the summer and other of the fall cutting season. The results showed that timbers with the pith shown in the centre should be avoided in the production of baby-squares because of its high propensity for bow, twist and surface checks, due to the problems with variable shrinkage coupling of juvenile and mature wood within specimens. Specimens with the pith shown close to one of the sides in the cross-section had a lower, but acceptable, quality according to the El20 CFLA grading rules. Because of the higher shrinkage, the lower target moisture content shows a greater risk for twist and surface checks, compared with the higher moisture content. The importance of the cutting season is reflected through its significant interactions with the target moisture content in the case of volumetric shrinkage, and with the pith location in the case of twist. These are consequences of lower initial moisture content in summer-cut specimens that could occasionally reach moisture content below the fiber saturation point, and start to shrink before kiln drying.

description: Five-dimensional $\mathcal{N}=1$ supersymmetric Yang-Mills theories are investigated from the viewpoint of random plane partitions. It is shown that random plane partitions are factorizable as q-deformed random partitions so that they admit the interpretations as five-dimensional Yang-Mills and as topological string amplitudes. In particular, they lead to the exact partition functions of five-dimensional $\mathcal{N}=1$ supersymmetric Yang-Mills with the Chern-Simons terms. We further show that some specific partitions, which we call the ground partitions, describe the perturbative regime of the gauge theories. We also argue their role in string theory.

description: B-DNA solutions of suitable concentration form left-handed chiral nematic phases (cholesterics). Such phases have also been observed in solutions of other stiff or semiflexible chiral polymers; magnitude and handedness of the cholesteric pitch are uniquely related to the molecular features. In this work we present a theoretical method and a numerical procedure which, starting from the structure of polyelectrolytes, lead to the prediction of the cholesteric pitch. Molecular expressions for the free energy of the system are obtained on the basis of steric and electrostatic interactions between polymers; the former are described in terms of excluded volume, while a mean field approximation is used for the latter. Calculations have been performed for 130 bp fragments of B-DNA. The theoretical predictions provide an explanation for the experimental behavior, by showing the counteracting role played by shape and charge chirality of the molecule.

description: Collisions between galaxy clusters dissipate enormous amounts of energy in the intra-cluster medium (ICM) through turbulence and shocks. In the process, Mpc-scale diffuse synchrotron emission in form of radio halos and relics can form. However, little is known about the very early phase of the collision. We used deep radio observations from 53 MHz to 1.5 GHz to study the pre-merging galaxy clusters A1758N and A1758S that are $\sim2$ Mpc apart. We confirm the presence of a giant bridge of radio emission connecting the two systems that was reported only tentatively in our earlier work. This is the second large-scale radio bridge observed to date in a cluster pair. The bridge is clearly visible in the LOFAR image at 144 MHz and tentatively detected at 53 MHz. Its mean radio emissivity is more than one order of magnitude lower than that of the radio halos in A1758N and A1758S. Interestingly, the radio and X-ray emissions of the bridge are correlated. Our results indicate that non-thermal phenomena in the ICM can be generated also in the region of compressed gas in-between infalling systems.

description: The manner in which electrolyte solutions respond to electric fields is crucial to understanding the behavior of these systems both at, and away from, equilibrium. The present formulation of linear response theory for such systems is inconsistent with common molecular dynamics (MD) implementations. Using the finite field formalism, suitably adapted for finite temperature MD, we investigate the response of bulk aqueous NaCl solutions to both finite Maxwell ($\mathbf{E}$) and electric displacement ($\mathbf{D}$) fields. The constant $\mathbf{E}$ Hamiltonian allows us to derive the linear response relation for the ionic conductivity in a simple manner that is consistent with the forces used in conventional MD simulations. Simulations of a simple point charge model of an electrolyte solution at constant $\mathbf{E}$ yield conductivities at infinite dilution within 15% of experimental values. The finite field approach also allows us to measure the solvent's dielectric constant from its polarization response, which is seen to decrease with increasing ionic strength. Comparison of the dielectric constant measured from polarization response versus polarization fluctuations enables direct evaluation of the dynamic contribution to this dielectric decrement, which we find to be small but not insignificant. Using the constant $\mathbf{D}$ formulation, we also rederive the Stillinger-Lovett conditions, which place strict constraints on the coupling between solvent and ionic polarization fluctuations.

description: The problem of distributed or decentralized detection and estimation in applications such as wireless sensor networks has often been considered in the framework of parametric models, in which strong assumptions are made about a statistical description of nature. In certain applications, such assumptions are warranted and systems designed from these models show promise. However, in other scenarios, prior knowledge is at best vague and translating such knowledge into a statistical model is undesirable. Applications such as these pave the way for a nonparametric study of distributed detection and estimation. In this paper, we review recent work of the authors in which some elementary models for distributed learning are considered. These models are in the spirit of classical work in nonparametric statistics and are applicable to wireless sensor networks.
