description: The research programme on multiple job holding identified substantial discrepancies between the Census and HLFS series regarding the increasing level of rural multiple job holding 1981 to 2001. Furthermore, evidence from the Time Use Survey suggests that the distribution of second job occupations does not match those for first jobs. This result and qualitative data indicate answers to census questions could lead to under-reporting of some rural occupations "hidden" as second jobs. Any under-reporting of the scale and form of the rural labour force in official statistics has implications for understanding rural occupations and industries, and formulation of rural policies.

description: The key resource in efficient production is the management input used to coordinate the land, labour and capital. Yet, our understanding of this resource is still somewhat limited, especially the factors involved in improving the managerial ability of farmers. This paper summarises three tests developed to help assess managers, and uses the data collected through random surveys of all types of farmers to explain the origins of managerial ability. Survey data on the competencies farmers' believe are important in successful management is reviewed, and finally a computer based teaching package to develop the important competencies is outlined. The tests developed cover managerial style, the locus of control, and aptitude.

description: Motu is currently developing a dataset of production costs relating to different rural land uses, which we can use to help explain historical land-use trends at a Territorial Authority level. The Meat and Wool Economic Service farm survey provides a rich database containing physical and financial data for New Zealand sheep and beef farms including detailed information on average farm expenditure, from at least 1980. But while this dataset provides extensive information for 8 farm classes and 5 regions, the actual location of the farms within each class is not known. So, we have developed an algorithm that generates a map of potential farm classes utilising supplementary information on farm location from QVNZ and a land productivity map developed by Baisden (2006) at Landcare Research. This map can be used to map any information contained with the farm survey reports.

description: The 2003 reform of the European Union's Common Agricultural Policy (CAP) replaced the coupled direct support schemes by a Single Farm Payment (SFP), which will be mainly delivered to farmers irrespective of what they produce (hence 'decoupled' from production). The level of decoupling differs among the Member States. This paper assesses the implementation of the SFP across Member States and how far it has been decoupled. The expected changes in the European Union's and New Zealand's trade in dairy products and beef resulting from the 2003 reform of the CAP are simulated, using a partial equilibrium trade model (Lincoln Trade and Environment Model; LTEM).

description: This article explores long-term land improvement (lime application) under land tenure insecurity on leased land. The dynamic optimisation problem is solved by a stochastic dynamic programming routine with known parameters for one-period returns and transition equations. The model parameters represent Finnish soil quality and production conditions. The farmer's decision rules are solved for alternative likelihood scenarios over the continuation of the fixed term lease contract. The results suggest that, as the probability for non-renewal of the lease contract increases, farmers quickly decrease investments in irreversible land improvement and, thereafter, yields decline gradually. The estimated decision rules are a part of larger set of farmer's decision rules to be taken care when land leasing and environmental legislation is renewed.

description: Large quantities of fresh produce can be grown in the Highlands provinces of Papua New Guinea, and this produce is then marketed to a range of markets, including the coastal cities of Port Moresby and Lae. However, it is often argued that the marketing system performs poorly, and various reasons for this are cited. In this paper, the results of a study on the marketing of smallholder produce originating in the Highlands provinces and destined for a range of markets, including the coastal cities, are presented. A defensible supply chain framework is used to evaluate a range of marketing issues and to evaluate the performance of the marketing system. The results of the study are refreshingly positive. It was found that the marketing system was remarkably vibrant, given the current level of market development in Papua New Guinea. It is characterised by entrepreneurial behaviour by the private sector, where businesses along the chain compete and innovate in order to expand their operations and meet the needs of the customers in their varied market segments. However, they are constrained in their endeavours by poor infrastructure, which raises their costs of doing business. It was concluded that the use of a Supply Chain Framework can yield a very robust and insightful understanding of the performance of the agricultural marketing system in developing economies.

description: Economics is an evolving and emerging field of study, so is the management of ecosystems. As such, this paper delineates the co-evolution of economic evaluation that reflects the various recognized ecosystem management approaches of anticipative, adaptive and capacitive ecosystem management. Each management approach is critiqued and from this theoretical analysis an emergent approach for the management of ecosystem is put forward, which accordingly suggests an alternative methodological approach for economic evaluations.

description: Using MUSE observations from the GASP survey, we study 54 galaxies undergoing ram-pressure stripping (RPS) spanning a wide range in galaxy mass and host cluster mass. We use this rich sample to study how the star formation rate (SFR) in the tails of stripped gas depends on the properties of the galaxy and its host cluster. We show that the interplay between all the parameters involved is complex and that there is not a single, dominant one in shaping the observed amount of SFR. Hence, we develop a simple analytical approach to describe the mass fraction of stripped gas and the SFR in the tail, as a function of the cluster velocity dispersion, galaxy stellar mass, clustercentric distance and speed in the intracluster medium. Our model provides a good description of the observed gas truncation radius and of the fraction of star-formation rate (SFR) observed in the stripped tails, once we take into account the fact that the star formation efficiency in the tails is a factor $\sim 5$ lower than in the galaxy disc, in agreement with GASP ongoing HI and CO observations. We finally estimate the contribution of RPS to the intracluster light (ICL) and find that the average SFR in the tails of ram-pressure stripped gas is $\sim 0.22 M_{\odot}\,\mathrm{yr}^{-1} $ per cluster. By extrapolating this result to evaluate the contribution to the ICL at different epochs, we compute an integrated average value per cluster of $\sim 4 \times 10^9 M_\odot$ of stars formed in the tails of RPS galaxies since $z\sim 1$.

description: Alchemical perturbation density functional theory has been shown to be an efficient and computationally inexpensive way to explore chemical compound space. We investigate approximations made, in terms of atomic basis sets and perturbation order,introduce an electron-density based estimate of errors of the alchemical prediction, and propose a correction for effects due to basis-set incompleteness. Our numerical analysis of potential energy estimates, and resulting binding curves, is based on CCSD reference results, and is limited to all neutral diatomics with 14 electrons (AlH ... N$_2$). The method predicts binding energy, equilibrium distance, and vibrational frequencies of neighbouring out-of-sample diatomics with near CCSD quality using perturbations up to 5$^{th}$ order. We also discuss simultaneous alchemical mutations at multiple sites in benzene.

description: The inner layers of a neutron star crust, composed of a Coulomb lattice of neutron rich nuclear clusters immersed in a sea of ``free'' superfluid neutrons, are closely analogous to periodic condensed matter systems such as electronic, photonic or phononic crystals. Applying methods from solid state physics to the neutron star context, we study the transport properties of those ``free'' neutrons for the outermost layers of the inner crust, near the drip point $ρ_{\rm drip} \sim 4\times 10^{11}$ g.cm$^{-3}$. In particular, we evaluate the effective neutron mass resulting from Bragg scattering by a band structure calculation. Comparison is made with the case of electrons in solids. The observational consequences are briefly discussed.

description: Surface tension (S) is due to the inward force experienced by particles at the surface and usually gravitation does not play an important role in this force. But in compact stars the gravitational force on the particles is very large and S is found to depend not only on the interactions in the strange quark matter, but also on the structure of the star, i.e. on its mass and radius. Indeed, it has been claimed recently that 511 keV photons observed by the space probe INTEGRAL from the galactic bulge may be due to electron-positron annihilation, and their source may be the positron cloud outside of an antiquark star. Such stars, if they exist, may also go a long way towards explaining away the antibaryon deficit of the universe. For that to happen S must be high enough to allow for survival of quark/antiquark stars born in early stages of the formation of the universe. High value of S may also assist explanation of delayed gamma-ray burst after a supernova explosion, as conversion from normal matter to strange matter takes place. The possibility of some implications from formation of surface waves are also discussed.

description: We study the exchange between electron and magnon spins at the interface of an antiferromagnet and a heavy metal at finite temperatures. The underlying physical mechanism is based on spin torque associated with the creation/annihilation of thermal magnons with right-hand and left-hand polarization. The creation/annihilation process depends strongly on the relative orientation between the polarization of the electron and the magnon spins. For a sufficiently strong spin transfer torque (STT), the conversion process becomes nonlinear, generating a nonzero net spin pumping current in the AFM that can detected in the neighboring metal layer. Applying an external magnetic field renders possible the manipulation of the STT driving thermal spin pumping. Our theoretical results are experimentally feasible and are of a direct relevance to antiferromagnet-based spintronic devices.

description: We discuss various issues concerning the behaviors near the boundary (σ=0,π) and the midpoint (σ=π/2) of the open string coordinate X(σ) and its conjugate momentum P(σ)=-iδ/δX(σ) acting on the matter projectors of vacuum string field theory. Our original interest is in the dynamical change of the boundary conditions of the open string coordinate from the Neumann one in the translationally invariant backgrounds to the Dirichlet one in the D-brane backgrounds. We find that the Dirichlet boundary condition is realized on a lump solution only partially and only when its parameter takes a special value. On the other hand, the string midpoint has a mysterious property: it obeys the Neumann (Dirichlet) condition in the translationally invariant (lump) background.

description: We present a comprehensive architectural analysis for a proposed fault-tolerant quantum computer based on cat codes concatenated with outer quantum error-correcting codes. For the physical hardware, we propose a system of acoustic resonators coupled to superconducting circuits with a two-dimensional layout. Using estimated physical parameters for the hardware, we perform a detailed error analysis of measurements and gates, including CNOT and Toffoli gates. Having built a realistic noise model, we numerically simulate quantum error correction when the outer code is either a repetition code or a thin rectangular surface code. Our next step toward universal fault-tolerant quantum computation is a protocol for fault-tolerant Toffoli magic state preparation that significantly improves upon the fidelity of physical Toffoli gates at very low qubit cost. To achieve even lower overheads, we devise a new magic-state distillation protocol for Toffoli states. Combining these results together, we obtain realistic full-resource estimates of the physical error rates and overheads needed to run useful fault-tolerant quantum algorithms. We find that with around 1,000 superconducting circuit components, one could construct a fault-tolerant quantum computer that can run circuits which are currently intractable for classical computers. Hardware with 18,000 superconducting circuit components, in turn, could simulate the Hubbard model in a regime beyond the reach of classical computing.

description: For all their ability to make us laugh, many comedians report severe struggles with mental health. Even so, this reality does not deter a growing number of improvisational (improv) comedians from endorsing applications of their craft in wellbeing-oriented workshops for the public, which claim to leverage the beneficial side effects of learning improv comedy to help with a growing list of psychological ailments like social anxiety and autism. This existential-phenomenological study explored the complex dynamics of wellbeing among eight professional improvisers (five men and three women) to illuminate the psychological vulnerabilities and resiliencies of this unique subset of the comedy community. Qualitative analysis yielded six common themes that conveyed the beneficial personal "by-products" of doing improv, which included the opportunity for adults to play, the joy of collaborative relationships, increased comfort with risk, improved confidence, a focus on positivity, and a revitalizing effect on emotional health, self-image, and sense of purpose. Stressors unique to the business aspect of improv, but not improv itself, were also revealed. Results provide valuable insights both for improvisers and those interested in the application of improv in clinical settings.

description: A method is proposed of constructing quantum correlators for a general gauge system whose classical equations of motion do not necessarily follow from the least action principle. The idea of the method is in assigning a certain BRST operator $\hatΩ$ to any classical equations of motion, Lagrangian or not. The generating functional of Green's functions is defined by the equation $\hatΩZ (J) = 0$ that is reduced to the standard Schwinger-Dyson equation whenever the classical field equations are Lagrangian. The corresponding probability amplitude $Ψ$ of a field $ϕ$ is defined by the same equation $\hatΩΨ(ϕ) = 0$ although in another representation. When the classical dynamics are Lagrangian, the solution for $Ψ(ϕ)$ is reduced to the Feynman amplitude $e^{\frac{i}{\hbar}S}$, while in the non-Lagrangian case this amplitude can be a more general distribution.

The cyanide heap leaching behavior of cupriferous gold ores
Creators: name: Tahvili, Mohammad Sasan
Publisher: name: University of British Columbia
Year: 2009

description: To develop a fundamental understanding of cyanide heap leaching of low-grade gold ores, with significant copper mineralization, two sets of column leach tests were operated under two different leaching solutions. In one set, four 1.5 m tall column tests were leached with sodium cyanide solution. In the second set, another four columns were leached with solutions of cyanocuprate complexes in the absence of free cyanide. Each set was run for a period of up to 200 days. The behavior of individual species, were investigated for the purpose of developing reliable rate parameters for the mathematical model. Significant amount of weak acid soluble copper minerals was discharged from the ore, simply by pre-rinsing with water. The cyanide leaching is shown to occur in different stages with remarkable characteristics as follows: (a) Significant decrease in the pH at the beginning of the cyanide column leach tests; (b) Reductive dissolution of the remaining WAS copper salts and dissolution of copper sulfide minerals, from the first day of the experiment; (c) Dissolution of gold from the first stage while no free cyanide is present in the solution; (d) The occurrence of two distinct peaks in copper concentration, first as the result of leaching of labile copper sulfides and second as the result of redissolution of copper cyanide precipitates; (e) Free cyanide breakthrough in the effluent, which is accompanied by the appearance of dissolved iron. The second set of column leach tests showed that the leaching of gold with a solution of cyanocuprate complex and in the absence of free cyanide is accessible with rate parameters comparable to leaching with cyanide. It is also concluded that some of the copper minerals can be leached in the absence of free cyanide. Iron does not show any dissolution in cyanocuprate leaching systems.

description: The ${\cal N}{=}8, 1D$ analytic bi-harmonic superspace is shown to provide a natural setting for ${\cal N}{=}8$ supersymmetric mechanics associated with the off-shell multiplet ${\bf (4, 8, 4)}$ . The latter is described by an analytic superfield $q^{1,1}$, and we construct the general superfield and component actions for any number of such multiplets. The set of transformations preserving the flat superspace constraints on $q^{1,1}$ constitutes ${\cal N}{=}8$ extension of the two-dimensional Heisenberg algebra {\bf h}(2), with an operator central charge. The corresponding invariant $q^{1,1}$ action is constructed. It is unique and breaks 1D scale invariance. We also find a one-parameter family of scale-invariant $q^{1,1}$ actions which, however, are not invariant under the full ${\cal N}{=}8$ Heisenberg supergroup. Based on preserving the bi-harmonic Grassmann analyticity, we formulate ${\cal N}{=}8, 1D$ supergravity in terms of the appropriate analytic supervielbeins. For its truncated version we construct, both at the superfield and component levels, the first example of off-shell $q^{1,1}$ action with local ${\cal N}{=}8, 1D$ supersymmetry. This construction can be generalized to any number of self-interacting $q^{1,1}$ .

description: HPC software stacks require administrators to deploy and maintain a complex collection of software. Historically this was done on bare-metal nodes, which present challenges when maintaining a coherent suite of software. This paper describes hosting administrative HPC software on a Kubernetes platform, along with auxilary tooling for storage, IP/DNS management, metrics and logging. Since Kubernetes exclusively runs container images, individual components of the software stack run in simplified, reproducible environments. Altogether, the platform can replicate most of the advantages of a bare-metal environment, while improving on reproducibility, stability, uptime, and the quality of telemetry.

description: Segmentation of structural parts of 3D models of plants is an important step for plant phenotyping, especially for monitoring architectural and morphological traits. Current state-of-the art approaches rely on hand-crafted 3D local features for modeling geometric variations in plant structures. While recent advancements in deep learning on point clouds have the potential of extracting relevant local and global characteristics, the scarcity of labeled 3D plant data impedes the exploration of this potential. We adapted six recent point-based deep learning architectures (PointNet, PointNet++, DGCNN, PointCNN, ShellNet, RIConv) for segmentation of structural parts of rosebush models. We generated 3D synthetic rosebush models to provide adequate amount of labeled data for modification and pre-training of these architectures. To evaluate their performance on real rosebush plants, we used the ROSE-X data set of fully annotated point cloud models. We provided experiments with and without the incorporation of synthetic data to demonstrate the potential of point-based deep learning techniques even with limited labeled data of real plants. The experimental results show that PointNet++ produces the highest segmentation accuracy among the six point-based deep learning methods. The advantage of PointNet++ is that it provides a flexibility in the scales of the hierarchical organization of the point cloud data. Pre-training with synthetic 3D models boosted the performance of all architectures, except for PointNet.

description: We construct some separable infinite dimensional homogeneous Hilbertian operator spaces which generalize the row and column spaces R and C. We show that separable infinite-dimensional Hilbertian JC*-triples are completely isometric to an element of the set of (infinite) intersections of these spaces. This set includes the operator spaces R, C, their intersection, and the space spanned by creation operators on the full anti-symmetric Fock space. In fact, we show that these new spaces are completely isometric to the space of creation (resp. annihilation) operators on the anti-symmetric tensors of the Hilbert space. Together with the finite-dimensional case studied in our previous paper, this gives a full operator space classification of all rank-one JC*-triples in terms of creation and annihilation operator spaces. We use the above to show that all contractive projections on a C*-algebra A with infinite dimensional Hilbertian range are ``expansions'' (which we define precisely) of normal contractive projections from the second dual of A onto a Hilbertian space which is completely isometric to one of the four spaces mentioned above. This generalizes the well known result, first proved for B(H) by Robertson, that all Hilbertian operator spaces that are completely contractively complemented in a C*-algebra are completely isometric to R or C. We also compute various completely bounded Banach-Mazur distances between these spaces.

description: This work is concerned about the asymptotic behavior of the solutions of the two and three dimensional stochastic convective Brinkman-Forchheimer (SCBF) equations driven by white noise with nonlinear diffusion terms. We prove the existence and uniqueness of weak pullback mean random attractors for the 2D SCBF equations (for $r\geq1$) as well as 3D SCBF equations (for $r>3$, any $μ,β>0$ and for $r=3$, $2μβ\geq1$) in Bochner spaces, when the diffusion terms are Lipschitz nonlinear functions. Furthermore, we establish the existence of weak pullback mean random attractors for a class of locally monotone stochastic partial differential equations.

description: We study the Non-Linear Born-Infeld(NLBI) scalar field model and quintessence model with two different potentials($V(ϕ)=-sϕ$ and ${1/2}m^2ϕ^2$). We investigate the differences between those two models. We explore the equation of state parameter w and the evolution of scale factor $a(t)$ in both NLBI scalar field and quintessence model. The present age of universe and the transition redshift are also obtained. We use the Gold dataset of 157 SN-Ia to constrain the parameters of the two models. All the results show that NLBI model is slightly superior to quintessence model.

description: The production of top-quark pairs in hadronic collisions is among the most important reactions in modern particle physics phenomenology and constitutes an instrumental avenue to study the properties of the heaviest quark observed in nature. The analysis of this process at the Large Hadron Collider relies heavily on Monte Carlo simulations of the final state events, whose accuracy is challenged by the outstanding precision of experimental measurements. In this letter we present the first matched computation of top-quark pair production at next-to-next-to-leading order in QCD with all-order radiative corrections as implemented via parton-shower simulations. Besides its intrinsic relevance for LHC phenomenology, this work also establishes an important step towards the simulation of other hadronic processes with colour charges in the final state.

In-Depth Behavior Understanding and Use: The Behavior Informatics Approach
Creators: name: Cao, Longbing
Publisher: name: arXiv

Subjects: subject: Social and Information Networks (cs.SI)
subject: FOS: Computer and information sciences

description: The in-depth analysis of human behavior has been increasingly recognized as a crucial means for disclosing interior driving forces, causes and impact on businesses in handling many challenging issues. The modeling and analysis of behaviors in virtual organizations is an open area. Traditional behavior modeling mainly relies on qualitative methods from behavioral science and social science perspectives. The so-called behavior analysis is actually based on human demographic and business usage data, where behavior-oriented elements are hidden in routinely collected transactional data. As a result, it is ineffective or even impossible to deeply scrutinize native behavior intention, lifecycle and impact on complex problems and business issues. We propose the approach of Behavior Informatics (BI), in order to support explicit and quantitative behavior involvement through a conversion from source data to behavioral data, and further conduct genuine analysis of behavior patterns and impacts. BI consists of key components including behavior representation, behavioral data construction, behavior impact analysis, behavior pattern analysis, behavior simulation, and behavior presentation and behavior use. We discuss the concepts of behavior and an abstract behavioral model, as well as the research tasks, process and theoretical underpinnings of BI. Substantial experiments have shown that BI has the potential to greatly complement the existing empirical and specific means by finding deeper and more informative patterns leading to greater in-depth behavior understanding. BI creates new directions and means to enhance the quantitative, formal and systematic modeling and analysis of behaviors in both physical and virtual organizations.
Kubernetes with Open OnDemand Using Kyverno
Creators: name: Dockendorf, Trey
Publisher: name: Zenodo

description: Supporting Kubernetes through Open OnDemand presents many challenges with regard to safely allowing users to run applications inside Kubernetes in a similar manner to how jobs would run in an High Performance Computing batch environment. To overcome these challenges, the Ohio Supercomputer Center has utilized the Kyverno policy engine to ensure that users using Kubernetes are doing so in a safe and secure way.

 The main challenge with user-submitted Kubernetes pods was ensuring that those pods are run as the UID/GID and supplemental groups belonging to that user. Additionally, there were challenges ensuring that users were authorized for the account they specified and could be charged for the resources consumed inside Kubernetes. These challenges were solved by deploying the Kyverno policy engine and implementing policies that ensure a user’s pod has certain required configurations set. Data from our local LDAP was used by the Kyverno policies to ensure not only correct UID/GID mappings but also that only active users are running pods. These changes are used to permit Kubernetes pods launched through Open OnDemand to have access to the same file systems as the HPC batch environment.
Determination of the mass loss rate and the terminal velocity of stellar winds. I Genetic algorithm for automatic line profile fitting
Creators: name: Georgiev, L.

Publisher: name: arXiv

description: Terminal wind velocity and mass loss rate are the most fundamental parameters of stellar winds. Unfortunately, their determination calls for high resolution spectroscopy in a range of wavelengths spanning from the ultraviolet to the infrared. For weak and/or distant objects, this becomes unfeasible. Nevertheless, it is possible to obtain an accurate estimate of these parameters through a simplified study of the formation processes of resonant lines which show P Cyg profiles. In this case, the line profile is a complex function of 6 parameters, with the radiative transport treatment becoming relatively inexpensive. However, preforming a 6 dimensional parameter fit raises a number of problems if one seeks an objective and automatic procedure to yield the optimal values, from which wind velocities and mass loss rates can be estimated. Useing a Likelihood function to construct a well defined statistical estimator of the goodness of fit which corresponds to a given model, we turn to a genetic algorithm through which we find the global maximum of the 6 dimensional Likelihood hyper-surface. We here present the implementation of the method, its successful testing with synthetic line profiles, where the answer is known in advance, together with first results of its application to real data

description: This report analyzes fruit and vegetable expenditures by low-income households and higher income households, and compares the sensitivity of both groups' purchases to changes in income. On average, low-income households spent $3.59 per capita per week on fruits and vegetables in 2000 while higher income households spent $5.02-a statistically significant difference. In addition, a statistical demand model indicates that marginal increases in income received by low-income households are not spent on additional fruits and vegetables. In contrast, increases in income received by higher income households do increase their fruit and vegetable expenditures. One interpretation of this finding is that low-income households will allocate an additional dollar of income to other food or nonfood items deemed more essential to the household such as meats, clothing, or housing.

description: In this paper, we investigate a nonlocal modification of general relativity (GR) with action $S = \frac{1}{16πG} \int [ R- 2Λ+ (R-4Λ) \, \mathcal{F}(\Box) \, (R-4Λ) ] \, \sqrt{-g}\; d^4x ,$ where $\mathcal{F} (\Box) = \sum_{n=1}^{+\infty} f_n \Box^n$ is an analytic function of the d'Alembertian $\Box$. We found a few exact cosmological solutions of the corresponding equations of motion. There are two solutions which are valid only if $Λ\neq 0, \, k = 0,$ and they have not analogs in Einsten's gravity with cosmological constant $Λ$. One of these two solutions is $ a (t) = A \, \sqrt{t} \, e^{\fracΛ{4} t^2} ,$ that mimics properties similar to an interference between the radiation and the dark energy. Another solution is a nonsingular bounce one -- $ a (t) = A \, e^{Λt^2}$. For these two solutions, some cosmological aspects are discussed. We also found explicit form of the nonlocal operator $\mathcal{F}(\Box)$, which satisfies obtained necessary conditions.
