description: The provision of services in rural areas is constrained by a number of issues arising from the remoteness of such areas and the relative sparsity of rural populations. These factors combine to increase the cost of supply and reduce the demand for services, which consequently threatens the viability of service provision whether by the public or private sectors. A possible to solution to these issues lies in the co-location of rural services, which in general means that two or more distinct services are located within the same premises thus reducing the delivery costs associated with one or more of these services. Beyond the simple economics of service provision lies the existence of non-market elements of services in terms of benefits to local communities of service provision that might arise from the social elements of local provided services such as community cohesion. This paper applies non-market valuation to quantify these benefits in three case studies across Scotland. The results indicate that relative degree of these benefits can be related to the remoteness of rural communities in that more remote communities particularly value the community aspects of services whereas less remote communities are more resistant to increased distances to access services. More generally, the results provide evidence on the inherent trade-offs between factors such as opening hours, levels of service and distance that can be used in determining the optimal configuration of service provision.

description: This paper investigates an indoor hybrid visible light communication (VLC) and radio frequency (RF) scenario with two-hop downlink transmission. A light emitting diode (LED) transmits both data and energy via VLC to an energy-harvesting relay node, which then uses the harvested energy to retransmit the decoded information to an RF user in the second phase. The design parameters include the direct current (DC) bias and the time allocation for VLC transmission. We formulate an optimization problem to maximize the data rate under decode-and-forward relaying with fixed receiver orientation. The non-convex problem is decomposed into two sub-problems, solved iteratively by fixing one parameter while optimizing the other. Additionally, we analyze the impact of random receiver orientation on the data rate, deriving closed-form expressions for both VLC and RF rates. An exhaustive search approach is employed to solve the optimization, demonstrating that joint optimization of DC bias and time allocation significantly enhances the data rate compared to optimizing DC bias alone.

description: This paper draws on the results of a multi-disciplinary research project funded by Defra1 which has focussed on identifying and developing practical approaches by which the dairy sector can reduce inputs and diffuse pollution, whilst maintaining biodiversity, product quality, high animal health and welfare standards and market competitiveness. The pressures on UK dairying for change towards greater economic and environmental sustainability derive from the need to remain profitable in the face of low farm-gate prices, competition from the global market in the context of a wide range of environmental and animal welfare constraints that have increased considerably in number and stringency during recent years. The challenge is to identify and develop practices that, through the use of integrated systems, incorporate environmental objectives into profitable, modern farming. The research has explored the complex interaction 'surfaces' of multiple sustainability criteria in systems simulations using an interactive framework of modelling (N, P, methane and production economics) and objective scoring matrices (biodiversity, landscape features, product quality and animal health). As part of the SIMSDAIRY model2, the EDMM (Economic Dairy Management Model) is an empirically-based model which simulates the revenue and costs attributed to dairy farming in the UK. At its core are a series of econometric relationships that replicate the underlying production and cost structures of dairy farm management. The results are presented and discussed in the context of recent market and policy developments in the milk supply sector.

description: Using an elementary method, we show that an odd number of Majorana fermions in $8k+1$ dimensions suffer from a gauge anomaly that is analogous to the Witten global gauge anomaly. This anomaly cannot be removed without sacrificing the perturbative gauge invariance. Our construction of higher-dimensional examples ($k geq1$) makes use of the SO(8) instanton on $S^8$.

description: The adoption of organic production has increased dramatically over recent years, especially in less developed countries. However, little information is available about who adopts, the difficulties they face in converting and how these factors vary over time. Using small-scale avocado producers (<15ha) from Michoacán, Mexico as a case study, this paper explores the factors affecting the time-to-adoption of organic production and certification, drawing from five parametric descriptions of the data. These models are implemented using a Bayesian approach and advances in Markov chain Monte Carlo methods. The results indicate that additional sources of income, together with membership of producers' associations, higher levels of education and experience of export markets, other than the US, have a positive effect on the adoption decision. Labour requirements and administrative capacity appear to be unimportant, while information sources and the frequency of contact with these sources have a varied, but largely negative effect on the probability of adoption. These findings raise a number of questions about the future of organic production in Mexico and the avocado zone, not least how to overcome credit and information constraints, but more importantly whether aiming for the organic market is a viable production strategy for small-scale producers.

description: Collimated sprays of hadrons, called jets, are an emergent phenomenon of Quantum Chromodynamics (QCD) at collider experiments, whose detailed internal structure encodes valuable information about the interactions of high energy quarks and gluons, and their confinement into color-neutral hadrons. The flow of energy within jets is characterized by correlation functions of energy flow operators, with the three-point correlator, being the first correlator with non-trivial shape dependence, playing a special role in unravelling the dynamics of QCD. In this Letter we initiate a study of the three-point energy correlator to all orders in the strong coupling constant, in the limit where two of the detectors are squeezed together. We show that by rotating the two squeezed detectors with respect to the third by an angle $ϕ$, a $\cos (2ϕ)$ dependence arising from the quantum interference between intermediate virtual gluons with $+/-$ helicity is imprinted on the detector. This can be regarded as a double slit experiment performed with jet substructure, and it provides a direct probe of the ultimately quantum nature of the substructure of jets, and of transverse spin physics in QCD. To facilitate our all-orders analysis, we adopt the Operator Product Expansion (OPE) for light-ray operators in conformal field theory and develop it in QCD. Our application of the light-ray OPE in real world QCD establishes it as a powerful theoretical tool with broad applications for the study of jet substructure.

description: The {\em sign pattern} defined by the real polynomial $Q:=Σ_{j=0}^da_jx^j$, $a_j\neq 0$, is the string $σ(Q):=({\rm sgn(}a_d{\rm )},\ldots ,{\rm sgn(}a_0{\rm )})$. The quantities $pos$ and $neg$ of positive and negative roots of $Q$ satisfy Descartes' rule of signs. A couple $(σ_0,(pos,neg))$, where $σ_0$ is a sign pattern of length $d+1$, is {\em realizable} if there exists a polynomial $Q$ with $pos$ positive and $neg$ negative simple roots, with $(d-pos-neg)/2$ complex conjugate pairs and with $σ(Q)=σ_0$. We present a series of couples (sign pattern, pair $(pos,neg)$) depending on two integer parameters and with $pos\geq 1$, $neg\geq 1$, which is not realizable. For $d=9$, we give the exhaustive list of realizable couples with two sign changes in the sign pattern.

description: The ability of African countries to achieve sustained improvements in agricultural incomes depends on their ability to generate total factor productivity (TFP) change in their agricultural sectors and adjust to movements in agricultural output and input prices. The single factoral terms of trade index measures these changes, calculated as changes in the product of TFP and the agricultural terms of trade. Estimates of the single factoral terms of trade index for the selected commodities over the period 1970-2002 are reported and discussed for 33 African countries for which data sets are available. The index is estimated for producers of coffee, cocoa, copra, palm kernel oil, coconut oil, palm oil, rice, cotton and sugar using annual agricultural sector data. Few countries managed to achieve an increase in the index over this period and it declined in many countries. In the light of the empirical evidence assembled, three broad strategic options are considered, covering agricultural trade reform, economic diversification strategies and strategies to improve total factor productivity in commodity production.
Do Maxwell's equations need revision? - A methodological note

description: We propose a modification of Maxwell's macroscopic fundamental set of equations in vacuum in order to clarify Faraday's law of induction. Using this procedure, the Lorentz force is no longer separate from Maxwell's equations. The Lorentz transformations are shown to be related to the convective derivative, which is introduced in the electrodynamics of moving bodies. The new formulation is in complete agreement with the actual set of Maxwell's equations for bodies at rest, the only novel feature is a new kind of electromotive force. Heinrich Hertz was the first to propose a similar electrodynamic theory of moving bodies, although its interpretation was based on the existence of the so called "aether". Examining the problem of a moving circuit with this procedure, it is shown that a new force of induction should act on a circuit moving through an inhomogeneous vector potential field. This overlooked induction force is related to the Aharanov-Bohm effect, but can also be related to the classical electromagnetic field when an external magnetic field is acting on the system. Technological issues, such as the so called Marinov motor are also addressed.

The relationship between adult attachment and personality : including normal personality and personality disorder
Creators: name: Clark, Megan Disa
Publisher: name: University of British Columbia

description: Despite the growing popularity of attachment theory, there has been little research examining how attachment fits with the more established construct of personality. An understanding of the relationship between attachment and personality is important, both for guiding future theory and research, and for providing insight into the etiology and treatment of interpersonal difficulties. This present study is a comprehensive examination of the relationship between adult attachment and a broad range of personality dimensions, including both normal personality and the extremes of personality characterized by personality disorder. A total of 213 adult volunteers from the community, aged 16-79 years (mean age = 31.4, SD =12.5) completed three self-report questionnaires: the Relationship Scales Questionnaire (RSQ) a dimensional assessment of attachment styles; the Eysenck Personality Questionnaire - Revised (EPQ-R), assessing normal personality dimensions; and the Dimensional Assessment of Personality Pathology - Differential Questionnaire (DAPP-DQ), assessing dimensions of personality disorder. Principal components analysis indicated that attachment, normal personality, and personality disorder share two underlying factors in common, one representing Emotional Distress, and one representing Intimacy Issues. These factors correspond to the dimensions of Anxiety and Avoidance theorized to underlie attachment. Regression analyses revealed that personality shares a moderate to modest proportion of variance with attachment, and that each attachment style is related to a unique pattern of personality and personality disorder dimensions. These patterns of predictor variables provide profiles of each attachment style that are theoretically supportable. Finally, a set of multiple regression analyses, using the four factors derived from the intercorrelations of the personality and personality disorder dimensions as predictors, provided further support for the theoretical dimensions of Anxiety and Avoidance underlying both attachment and personality. A more complete picture of the relationship between attachment and personality resulting from this study will help guide nature theory and research, as well as provide clinicians with insight into the etiology and treatment of personality disorders associated with interpersonal difficulties.

description: Two policy instruments, input taxes and regulations, can be used to deal with nitrate pollution. However, in practice command and control (CAC) measures such as input regulations and management practices, as outlined in Action Programmes under the EU Nitrates Directive, rather than economic instruments, are commonly used to deal with nitrate pollution from agricultural sources. Action Programmes are to meant to ensure that the applications of nitrogen to farmland are within limits calculated to avoid a level of nitrate emissions to water supplies that would put them above the concentration limit of 50mg/litre specified in the Directive. The premise of the Action Programmes is that farmers should take all reasonable steps to prevent or minimise the application to land of fertilisers in excess of crop requirements. To this end the Irish Action Programme specifies that the amount of livestock manure applied in any year to land on a holding, together with that deposited to land by livestock, cannot exceed an amount containing 170 kg nitrogen per hectare (ha) and also sets limits on the application of inorganic (manufactured) nitrogen. However, the objective of the Nitrates Directive, at least in terms of organic and inorganic nitrogen application rates, could theoretically be achieved by imposing a tax on nitrogen inputs. This paper tests the hypotheses that the objectives of the Nitrates Directive, in terms of organic and inorganic N application rates, would be more effectively and more equitably achieved by regulation, than by a tax. The results of the analysis indicate that this is the case.

description: We investigate the mathematics behind unshuffles, a type of card shuffle closely related to classical perfect shuffles. To perform an unshuffle, deal all the cards alternately into two piles and then stack the one pile on top of the other. There are two ways this stacking can be done (left stack on top or right stack on top), giving rise to the terms left shuffle ($L$) and right shuffle ($R$), respectively. We give a solution to a generalization of Elmsley's Problem (a classic mathematical card trick) using unshuffles for decks with $2^k$ cards. We also find the structure of the permutation groups $\langle L, R \rangle$ for a deck of $2n$ cards for all values of $n$. We prove that the group coincides with the perfect shuffle group unless $n\equiv 3 \pmod 4$, in which case the group $\langle L, R \rangle$ is equal to $B_n$, the group of centrally symmetric permutations of $2n$ elements, while the perfect shuffle group is an index 2 subgroup of $B_n$.

description: The flavour problem of the Standard Model can be addressed through the Froggatt-Nielsen (FN) mechanism. In this work, we develop an approach to the study of FN textures building a direct link between FN-charge assignments and the measured masses and mixing angles via unitary transformations in flavour space. We specifically focus on the quark sector to identify the most economic FN models able to provide a dynamical and natural understanding of the flavour puzzle. Remarkably, we find viable FN textures, involving charges under the horizontal symmetry that do not exceed one in absolute value (in units of the flavon charge). Within our approach, we also explore the degree of tuning of FN models in solving the flavour problem via a measure analogous to the Barbieri-Giudice one. We find that most of the solutions do not involve peculiar cancellations in flavour space.

description: In the wake of policy reforms such as the MTR of the CAP and WTO arrangements, many policy analysts are questioning the value of retaining the EU milk quota system in its current form and one policy reform option that has been discussed in advance of the 2008 "Health Check" of the CAP is the international transfer of quota rights between member states. A methodology for simulating a "free market" for milk quota is outlined in this paper with a view to extending the work to other member states to determine which member states would supply and demand milk quota if an international market for quotas was established. The analysis, conducted for Ireland, uses National Farm Survey data from 491 dairy farms to estimate the aggregate demand for and supply of milk quota. A profit maximization model is used to simulate the production decisions of farmers and aggregation techniques are applied to arrive at national and regional demand and supply curves. Two policy scenarios are analysed; one assumes that there is no WTO reform and that the policies agreed under the MTR of the CAP in 2003 continue indefinitely, the second scenario assumes that a WTO agreement is reached and that export subsidies are phased out. The analysis also considers the effect of the Single Farm Payment on the market for milk quota and a sensitivity analysis is conducted on the lifespan of the milk quota. The methodologies developed in this paper, offer policy makers in Ireland a useful tool to analyse the effect of imposing different constraints on the milk quota market, be they regional, volume based or some other measures. The analysis also offer some insight into the capitalisation of policy measures into asset values; this is evident from the substantially lower market equilibrium price for quotas in a scenario where there is no export subsidies relative to a continuation of these policies and also from the effect of re-investment of the Single Farm Payment on quota values. The approach adopted is sufficiently general to be applied to FADN data for the major dairy producing countries in Europe to determine where milk production may move to if there was an international free market for quota rights.

description: A number of studies have tested economic models of household decision-making, yet there is no consensus regarding which is most appropriate for practical application. One area where the choice of household decision model has potentially important implications is the valuation of child health or safety. Few child health valuation studies have investigated household decision-making models, typically adopting the simplifying unitary model. This study aims to determine the implications of household decision making models on the magnitude of a child safety premium. To achieve this, a stated preference survey is conducted amongst farm households in Northern Ireland to ascertain mothers' and fathers' individual preferences regarding the value of reducing the risk of non-fatal farm accidents to their child relative to themselves. A number of interesting results emerge. Firstly, no significant difference is found between child values elicited from mothers and fathers. Secondly, the premium, which suggests that fathers are willing to pay twice as much for their child than self, is consistent with previous findings. Finally, the affect of different household models on the value of the premium will be investigated. Results show that the premium magnitude varies, with midpoint values of 1.25 from the bargaining model, 1.5 from the collective model and 2 from the unitary model.

Farm Management

description: Many scientific publications discussing the effects of climate change on the agricultural system express these in terms of changing crop production at coarse spatial and temporal scales. But in agro-economy, where crop production is the result of the interaction between bio-physical and management components, the temporal drivers operate at much smaller resolutions. Climate change affects the agricultural system via the interrelated, bio-physical layers of air, water, soil and crops. Furthermore, it influences the farm-system manager in their choice of their crops. In our paper the main question is how to deal systematically with the different time extents and time resolutions when studying agricultural management impacts due to climatic change. Agent based modeling offers an elegant way to tackle such challenges, where agents represent simplified farm managers. The agricultural management model is dynamically connected to a regional agro-economic model, a ground water model, a crop growth model and a soil model. Hence, we endogonize climatic change and make its effects a (risk)-factor in the agents considerations along different temporal scales. This paper reports on the fundamental issues regarding use of different temporal modeling scales with several clear practical examples.

description: We use Mellin space dispersion relations together with Polyakov conditions to derive a family of sum rules for Conformal Field Theories (CFTs). The defining property of these sum rules is suppression of the contribution of the double twist operators. Firstly, we apply these sum rules to the Wilson-Fisher model in $d=4-ε$ dimensions. We re-derive many of the known results to order $ε^4$ and we make new predictions. No assumption of analyticity down to spin $0$ was made. Secondly, we study holographic CFTs. We use dispersive sum rules to obtain tree-level and one-loop anomalous dimensions. Finally, we briefly discuss the contribution of heavy operators to the sum rules in UV complete holographic theories.

description: Australian wool producers have been slow to adopt price risk management strategies to stabilise the income from their wool sales. The highly volatile auction system accounts for 85% of raw wool sales while the remainder is sold by forward contract, futures and other hedging methods. Qualitative analysis was used to find behavioural factors associated with the adoption of price risk management strategies (specifically futures and forward contracts) for selling raw wool. Consideration was given to Diffusion of Innovations and the Theory of Planned Behaviour as theoretical frameworks in order to answer the research question: Are there any non-traditional behavioural factors that need to be incorporated into existing frameworks to determine adoption of price risk management strategies for selling raw wool? In contrast to these prominent theories, data from four focus groups conducted with wool producers in regional Western Australia showed that trust, habit and social cohesion were the major behavioural determinants that governed the adoption of price risk management strategies. The significance of this paper lies in its multi-disciplinary approach to understanding the dimensions of farm-level decision making.

Cloning and expression of genes encoding divergent 4-coumarate : CoA ligase in poplar
Creators: name: Cukovic, Daniela
Publisher: name: University of British Columbia
Year: 2009

description: The enzyme 4-coumarate:Coenzyme A ligase catalyzes the third and final step in the general phenylpropanoid metabolic pathway, providing activated thioester substrates for different phenylpropanoid products. To clone putative divergent members of the poplar 4CL gene family, degenerate primers directed to a part of the first exon, containing a putative AMP-binding motif, were used. Three new 4CL-like classes were distinguished among 72 cloned PCR amplification products. The new 4CL-like sequence classes, arbitrarily named 4CL6, 4CL10 and 4CL14, shared 61% to 96% deduced amino acid sequence identity over the 600 bp region compared. A full-length cDNA clone of 4CL6 was isolated by screening a xylem cDNA library with the PCR fragment. Isolation of a full-length cDNA clone of 4CL10 involved both screening a young leaf cDNA library, and 5' and 3' RACE. Sequence analysis showed that the most divergent member of the poplar 4CL gene family is 4CL10 (61% -65% amino acid identity with others), while 4CL6 is moderately divergent to previously isolated members. RNA blot analysis showed that the 4CL6 gene is expressed exclusively in xylem, green stem and root, while 4CL10 expression is restricted to young leaf, old leaf and root. Recombinant enzymes corresponding to the 4CL6 and 4CL10 genes were expressed using a baculovirus system. The recombinant 4CL6 was partially purified by FPLC, and showed a substrate utilization profile (4-coumaric acid > ferulic acid > caffeic acid > cinnamic acid, and no activity toward sinapic acid) similar to the profiles of the previously studied native and recombinant 4CL proteins.

description: The capability to extract task specific, semantic information from raw sensory data is a crucial requirement for many applications of mobile robotics. Autonomous inspection of critical infrastructure with Unmanned Aerial Vehicles (UAVs), for example, requires precise navigation relative to the structure that is to be inspected. Recently, Artificial Intelligence (AI)-based methods have been shown to excel at extracting semantic information such as 6 degree-of-freedom (6-DoF) poses of objects from images.
 In this paper, we propose a method combining a state-of-the-art AI-based pose estimator for objects in camera images with data from an inertial measurement unit (IMU) for 6-DoF multi-object relative state estimation of a mobile robot. The AI-based pose estimator detects multiple objects of interest in camera images along with their relative poses. These measurements are fused with IMU data in a state-of-the-art sensor fusion framework. We illustrate the feasibility of our proposed method with real world experiments for different trajectories and number of arbitrarily placed objects. We show that the results can be reliably reproduced due to the self-calibrating capabilities of our approach.

description: Several recent experiments, including our own in the fission yeast, S. pombe, have characterized the motions of gene loci within living nuclei by measuring the locus position over time, then proceeding to obtain the statistical properties of this motion. To address the question of whether a population of single particle tracks, obtained from many different cells, corresponds to a single mode of diffusion, we derive theoretical equations describing the probability distribution of the displacement covariance, assuming the displacement is a zero-mean multivariate Gaussian random variable. We also determine the corresponding theoretical means, variances, and third central moments. Bolstering the theory is good agreement between its predictions and the results obtained for various simulated and measured data sets, including simulated particle trajectories of simple and anomalous diffusion, and the measured trajectories of an optically-trapped bead in water, and in a viscoelastic solution. We also show that, for sufficiently long tracks, each covariance distribution in these examples is well-described by a skew-normal distribution with mean, variance, and skewness given by theory. For experimental S. pombe gene locus data, however, we find that the first two covariance distributions are wider than predicted, although the third and subsequent covariances are well-described by theory. This suggests that the origin of the theory-experiment discrepancy is associated with localization noise, which influences only the first two covariances. Thus, we hypothesize that the discrepancy is caused by locus-to-locus heterogeneity in the localization noise. Further simulations reveal excess covariance widths can be largely recreated on the basis of heterogeneous noise. We conclude that the motion of gene loci in fission yeast is consistent with a single mode of diffusion.

description: In this letter, we discuss generation of magnetic field from cosmological perturbations. We consider the evolution of three component plasma (electron, proton and photon) evaluating the collision term between elecrons and photons up to the second order. The collision term is shown to induce electric current, which then generate magnetic field. There are three contributions, two of which can be evaluated from the first-order quantities, while the other one is fluid vorticity which is purely second order. We estimate the magnitudes of the former contributions and shows that the amplitude of the produced magnetic field is about $\sim 10^{-19} {\rm G}$ at 10Mpc comoving scale at the recombination. Compared to astrophysical and inflationary mechanisms for seed-field generation, our study suffers from much less ambiguities concerning unknown physics and/or processes.

description: Land use concepts for ecologically particularly sensitive agricultural landscapes are often focussed on the attainment of specific environmental objectives in specific areas, neglecting both socio-economic effects, in particular income effects, and the farmers' income-driven production responses outside these areas. The paper illustrates, on the basis of an empirical study on the land use in the southern German region Bayerisches Donauried, (1) that the farmers' objectives and production responses need to be integrated in land use concepts for agricultural landscapes because of their potentially counterproductive effects on the attainment of environmental objectives, and (2) how multi-criteria analysis (MCA) can be used to transform a primarily ecology-oriented land use concept for an ecologically very sensitive agricultural landscape into a more comprehensive one that makes due allowance for the farmers' responses and society's socio-economic objectives. The authors show that such integration of socioeconomic objectives can contribute to the maintenance of incomes and employment without overly harming the attainment of ecological goals. As far as the MCA is concerned, two methods are applied: The linear-additive model, and the outranking model ELECTRE. The models serve to evaluate four different land use options. Nine criteria are used, derived from the relevant landscape functions. Weights are based on written interviews with major decision-makers, and stakeholders of the region. The major assumptions underlying the models are discussed. The authors interpret the results of each model on the basis of sensitivity analyses, and compare them. Finally, the paper discusses policy implications resulting from the implementation of land use concepts for agricultural landscapes, in particular the question of a "regionalisation" of agri-environmental policy, and raises some administrative and practical issues that come up if policy makers apply MCA more widely in the design of such concepts.

description: This paper analyses the relationship between Spanish household consumption patterns and atmospheric pollutant emissions in 2000. Applying an input-output approach we estimate the relative responsibility of different types of households in the emissions of nine different atmospheric pollutants: the six greenhouse gases (CO2, CH4, N2O, SF6, HFCs and PFCs) regulated by the Kyoto protocol and three other gases (SO2, NOx and NH3). We combine input-output tables, national consumer survey statistics and environmental pollution satellite accounts into an environmental extended input-output model. We also analyse the assumptions required in order to apply the model to available data. We find that there is a positive and very high relationship between the level of household expenditure and the direct and indirect emissions generated by household consumption. However, the emission intensities tend to decrease with the expenditure level for the different atmospheric pollutants, with the exception of the synthetic greenhouse gases (SF6, HFCs and PFCs).

description: Many approaches to galaxy dynamics assume that the gravitational potential is simple and the distribution function is time-invariant. Under these assumptions there are traditional tools for inferring potential parameters given observations of stellar kinematics (e.g., Jeans models). However, spectroscopic surveys measure many stellar properties beyond kinematics. Here we present a new approach for dynamical inference, Orbital Torus Imaging, which makes use of kinematic measurements and element abundances (or other invariant labels). We exploit the fact that, in steady state, stellar labels vary systematically with orbit characteristics (actions), yet must be invariant with respect to orbital phases (conjugate angles). The orbital foliation of phase space must therefore coincide with surfaces along which all moments of all stellar label distributions are constant. Both classical-statistics and Bayesian methods can be built on this; these methods will be more robust and require fewer assumptions than traditional tools because they require no knowledge of the (spatial) survey selection function and they do not involve second moments of velocity distributions. We perform a classical-statistics demonstration with red giant branch stars from the APOGEE surveys: We model the vertical orbit structure in the Milky Way disk to constrain the local disk mass, scale height, and the disk--halo mass ratio (at fixed local circular velocity). We find that the disk mass can be constrained (naïvely) at the few-percent level with Orbital Torus Imaging using only eight element-abundance ratios, demonstrating the promise of combining stellar labels with dynamical invariants.

description: We construct examples of smooth periodic solutions to the Magnetohydrodynamic equations in dimension 2 with positive resistivity for which the topology of the magnetic lines changes under the flow. By Alfvén's theorem this is known to be impossible in the ideal case (resistivity = 0). In the resistive case the reconnection of the magnetic lines is known to occur and has deep physical implications, being responsible for many dynamic phenomena in astrophysics. The construction is a simplified proof of [3] and in addition we consider the case of the forced system.
