description: This paper sets out to develop an economic framework for ex post evaluations of agri-environmental schemes. We begin by developing a non-parametric model for estimating farm-level environmental efficiency scores. We then use this efficiency framework to devise a set of economic criteria for evaluating agri-environmental schemes. One key criterion is whether an environmental scheme has given rise to an increase in environmental efficiency scores across participating farms, relative to a counterfactual group of non participants. We finally demonstrate the potential usefulness of the framework by applying it to a fictitious multiple-objective conservation programme. The dataset is made up of 100 fictitious farms, half of which participate in the environmental programme. Each farm is characterised by a set of financial and environmental performance indicators. The results of this mock evaluation show that the proposed evaluation framework generates useful insights into the performance of the scheme and permits identification of potential improvements.

In this study, a 33 full factorial design methodology was used to analyze the effects of spray parameters on the thickness, hardness, and surface porosity of low-pressure cold-sprayed WC-17Ni coatings. Three levels were selected for the spray parameters included in the design which were the powder feed rate (17.1 g/min, 21.1 g/min, and 23.7 g/min), gas temperature (475°C, 500°C, and 525°C), and the nozzle to substrate stand-off distance (3 mm, 5 mm, and 10 mm). It was found that the feed rate was the most significant parameter that affected the coating thickness. The surface porosity was most significantly affected by stand-off distance. The coating hardness was most influenced by the interaction between the feed rate and stand-off distance. An optimization study was then performed to maximize the coating thickness and hardness while minimizing the surface porosity. The optimal spray parameters (OSP) were found to be at a feed rate of 23.7 g/min, 500°C for the carrier gas temperature, and 10 mm for the stand-off distance. The OSP yielded a coating that was 1.22 ± 0.06 mm thick, with a hardness of 364.5 ± 8.5 HV and porosity of 6.8 ± 0.6%. With a multi-parameter process, the system response is affected by both the variation in the individual parameters and the interaction of the parameters with each other. It was also concluded that the interaction between the parameters significantly affected the coating hardness. These results suggest that variation of the selected parameters produce statistically significant effects on the coating quality of WC-17Ni coatings using a low-pressure cold spray system.

description: We study theoretically the quantum dynamics of two interacting electrons in the symmetric double-dot structure under the influence of the bichromatic resonant pulse. The state vector evolution is studied for two different pulse designs. It is shown that the laser pulse can generate the effective exchange coupling between the electron spins localized in different dots. Possible applications of this effect to the quantum information processing (entanglement generation, quantum state engineering) are discussed.

description: It is important to develop valid field tools that can identify homogeneous farming situations that facilitates offering of appropriate agricultural technology to farmers. The present study was conducted to test the validity of such a novel participatory field tool that can identify micro farming situation with special reference to rainfed rice cultivation in selected village of North 24 Parganas District of West Bengal, India. A Micro farming situation was conceptualised as a sub-system of a relatively large farming situation, which is relatively homogeneous in nature. Farmers of the village themselves classified their agricultural fields into distinct micro-farming situations through participatory mapping exercise. All the 70 farmers growing rainfed rice in that uninterrupted field were then interviewed for recording their rainfed rice cultivation practices. Most of the rainfed rice cultivation practices like variety selection, time of sowing, transplanting and harvesting, seed rate, seedling age, spacing, plant protection practices, fertilizer management and yield differed significantly among these identified micro-farming situations. This indicated the effectiveness of farmers’ classification. However, more empirical evidence is needed – especially for different field crops – to establish the validity of this tool. The tool can help to offer appropriate technologies to the farmers for a technically precise and environmentally sound agriculture.

Digital Archaeological Archiving in Poland – SEADDA Cost Action and Beyond

Digitisation

description: During the SEADDA COST Action, the National Institute of Cultural Heritage in Poland investigated the preservation of digital archaeological data. The main focus was on state heritage service, which operates within the binding legal framework. The study has revealed that, despite the digital shift observed in many areas of life, particularly since the pandemic, state services responsible for archaeological heritage are lagging behind. The lack of a dedicated repository that would enable access and re-use, and the absence of a long-term national strategy for the digitisation of archaeology- related administrative processes has resulted in data fragmentation and general inaccessibility. Heritage professionals across the country are not fully utilizing the potential of properly preserved advanced archaeological records. An analysis of archaeological archiving practices in state heritage services, combined with a European overview of the current situation, has allowed for the identification of various levels of an ideal digitisation strategy. This includes targeting law and policy makers, as expressed in the EAC’s ‘call for action’ (Novak et al. 2023), developing and implementing digital tools, and ensuring systematic training and contact points for users. These findings are universal; however, the paper will discuss their practical application in the Polish context and provide an update on the current state-of-the-art.

description: We develop a microscopic theory for biasing the quantum trajectories of an open quantum system, which renders rare trajectories typical. To this end we consider a discrete-time quantum dynamics, where the open system collides sequentially with qubit probes which are then measured. A theoretical framework is built in terms of thermodynamic functionals in order to characterize its quantum trajectories (each embodied by a sequence of measurement outcomes). We show that the desired biasing is achieved by suitably modifying the Kraus operators describing the discrete open dynamics. From a microscopical viewpoint and for short collision times, this corresponds to adding extra collisions which enforce the system to follow a desired rare trajectory. The above extends the theory of biased quantum trajectories from Lindblad-like dynamics to sequences of arbitrary dynamical maps, providing at once a transparent physical interpretation.

description: To observationally explore physical processes, we present a multi-wavelength study of a wide-scale environment toward l = 13.7 - 14.9 degrees containing a mid-infrared bubble N14. The analysis of 12CO, 13CO, and C18O gas at [31.6, 46] km/s reveals an extended physical system (extension ~59 pc x 29 pc), which hosts at least five groups of the ATLASGAL 870 micron dust clumps at d ~3.1 kpc. These spatially-distinct groups/sub-regions contain unstable molecular clumps, and are associated with several Class I young stellar objects (mean age ~0.44 Myr). At least three groups of ATLASGAL clumps associated with the expanding HII regions (including the bubble N14) and embedded infrared dark clouds, devoid of the ionized gas, are found in the system. The observed spectral indices derived using the GMRT and THOR radio continuum data suggest the presence of non-thermal emission with the HII regions. High resolution GMRT radio continuum map at 1280 MHz traces several ionized clumps powered by massive B-type stars toward N14, which are considerably young (age ~10^3 - 10^4 years). Locally, early stage of star formation is evident toward all the groups of clumps. The position-velocity maps of 12CO, 13CO, and C18O exhibit an oscillatory-like velocity pattern toward the selected longitude range. Considering the presence of different groups/sub-regions in the system, the oscillatory pattern in velocity is indicative of the fragmentation process. All these observed findings favour the applicability of the global collapse scenario in the extended physical system, which also seems to explain the observed hierarchy.

description: The most massive and complex globular clusters in the Galaxy are thought to have originated as the nuclear cores of now tidally disrupted dwarf galaxies, but the connection between globular clusters and dwarf galaxies is tenuous with the M54/Sagittarius system representing the only unambiguous link. The globular cluster Omega Centauri (w Cen) is more massive and chemically diverse than M 54, and is thought to have been the nuclear star cluster of either the Sequoia or Gaia-Enceladus galaxy. Local Group dwarf galaxies with masses equivalent to these systems often host significant populations of very metal-poor stars ([Fe/H] < -2.5), and one might expect to find such objects in w Cen. Using high resolution spectra from Magellan-M2FS, we detected 11 stars in a targeted sample of 395 that have [Fe/H] ranging from -2.30 to -2.52. These are the most metal-poor stars discovered in the cluster, and are 5x more metal-poor than w Cen's dominant population. However, these stars are not so metal-poor as to be unambiguously linked to a dwarf galaxy origin. The cluster's metal-poor tail appears to contain two populations near [Fe/H] ~ -2.1 and -2.4, which are very centrally concentrated but do not exhibit any peculiar kinematic signatures. Several possible origins for these stars are discussed.

description: In Bangladesh, climatic change is likely to impact significantly upon surface and groundwater availability, as well as in other countries. The population of Bangladesh is projected to be double the current 2010 level by 2050. Demand for water will rise with the increasing demand for rice. This paper considers the optimal demand management of irrigation water with stochastic supply under climate change for a 3-year planning horizon. It also identifies the utilization of irrigation water from surface water sources to maximize the expected net social return from rice production. This is done by considering decision on dam release for rice production with reference to climate change. A stochastic dynamic programming model is developed for analyzing the levels and timing of the allocation of surface water for irrigation. The objective is to find the optimal dam release for irrigation which results in the maximum expected present value of the stream of annual net social return from rice production for the 3 years from 2012 to 2014. Net social return in a year consists of the value of rice consumed, measured by consumers’ willingness to pay for rice, less the total cost of rice production. The paper also identifies the need for irrigation infrastructure and determines the optimal investment policies for the adaptation to climate change in Bangladesh agriculture.
Essays on exchange rate volatility and optimal monetary policy
Creators: name: Xu, Juanyi
Publisher: name: University of British Columbia
Year: 2009

description: This thesis consists of three essays on exchange rate behavior and optimal monetary policy in open economy. The first essay proposes a framework to explain why the nominal and real exchange rates are highly volatile and seem to be disconnected from macroeconomic fundamentals. Two types of foreign exchange traders, rational traders and noise traders with erroneous stochastic beliefs, are introduced into a dynamic general equilibrium model with sticky prices. The presence of noise traders creates deviations from uncovered interest parity. As a result, exchange rates can diverge significantly from fundamental values. Combined with local currency pricing and consumption smoothing behavior in an infinite horizon model, the presence of noise traders can help to explain the "exchange rate disconnect puzzle". The second essay explores the optimal monetary policy response to domestic and foreign technology shocks in an open economy with vertical structure of production and trade. Through the vertical linkage in production, any stage-specific productivity shock in one country has a trans-border spillover effect on the other country via vertical trade. So when choosing the optimal monetary rules, each monetary authority should respond to both home and foreign productivity shocks. Another finding is that the flexible exchange rate can not replicate the flexible price equilibrium even under producer currency pricing due to price stickiness in multiple stages. Finally, the exchange rate in such an environment will be more stable than that of an economy without vertical structure of production and trade. The third essay analyzes the determination of monetary policy in a world with a dollar standard, defined here as an environment in which all traded goods prices are set in US dollars. This generates an asymmetry whereby exchange rate pass-through into the US CPI is zero, while pass-through to other countries will be positive. I find that in such an economy, the US is essentially indifferent to exchange rate volatility in setting monetary policy, while the rest of the world places a high weight on exchange rate volatility. More importantly, in a Nash equilibrium of the monetary policy game between the US and the rest of the world, the preferences of the US dominate. Despite this, the US loses from the dollar's role as an international currency due to the absence of exchange rate pass-through even though US preferences dominate world monetary policy.

description: This paper uses variance decomposition modelling to explore how wheat revenue volatility in Australia has changed spatially and temporally. The components of revenue variance are the variances and covariances of wheat prices, the area of wheat harvested and the yield of wheat. The key finding is that the volatility of wheat revenue (detrended) has more than doubled in every main wheat-growing State in Australia over the last 15 years or so Changes in wheat areas are mostly a minor source of revenue variance. The principal cause of volatility is yield changes with price changes increasing slightly in absolute importance when compared to their adjacent previous period. Greater downside yield risk is often the principal cause of the increased yield variance. The implications are that revenue variance, and especially downside revenue risk, has posed major problems for wheat-dominant farm businesses over the last 15 years or so. How Australia’s wheat producers have managed this greater volatility of wheat revenue is likely to have greatly affected the viability of their farm businesses.

description: We face the problems of correctness, optimality and precision for the static analysis of logic programs, using the theory of abstract interpretation. We propose a framework with a denotational, goal-dependent semantics equipped with two unification operators for forward unification (calling a procedure) and backward unification (returning from a procedure). The latter is implemented through a matching operation. Our proposal clarifies and unifies many different frameworks and ideas on static analysis of logic programming in a single, formal setting. On the abstract side, we focus on the domain Sharing by Jacobs and Langen and provide the best correct approximation of all the primitive semantic operators, namely, projection, renaming, forward and backward unification. We show that the abstract unification operators are strictly more precise than those in the literature defined over the same abstract domain. In some cases, our operators are more precise than those developed for more complex domains involving linearity and freeness. To appear in Theory and Practice of Logic Programming (TPLP)

description: This paper develops a heterogeneous-agent model to assess the impacts of removing lucerne growing subsidies, increasing livestock numbers and including district-level equilibrium conditions on optimal farm plans in the Qingyang district of Gansu Province, China. The model is a five-year dynamic linear program that solves across 96 farm households whilst incorporating district-level constraints. The approach used allows us to observe seasonal variations in incomes, infer the distribution of a policy shock among households and highlight trade patterns at the district level. The results suggest that without lucerne growing subsidies the total area of lucerne grown by all modelled households falls by 18%. Increasing livestock numbers by 25% reduces net household incomes by 17% as changes to labour allocations reduce off-farm employment opportunities. When external trade in forages is included in the model, total livestock numbers held by all 96 households rise from 502 to 838, this highlights the benefits of integrated feed markets. Shadow prices for crop production rise when livestock numbers increase, implying that benefits exist to improving crop yields.
Scaling of Power Corrections for Angularities from Dressed Gluon Exponentiation

description: We study power corrections to a recently introduced family of event shapes, the class of angularities, within the formalism of dressed gluon exponentiation (DGE). We find that the universal scaling rule for the leading power corrections deduced from resummation also holds when taking renormalon enhancements into account. The scaling is due to boost invariance of eikonal dynamics in the two-jet limit, which we recover in the context of DGE. Furthermore, dressed gluon exponentiation provides an ansatz for non-leading power corrections that violate the scaling. These non-leading corrections are further suppressed by non-integer powers of the hard scale.

description: We establish a hidden extension in the Adams spectral sequence converging to the stable homotopy groups of spheres at the prime 2 in the 54-stem. This extension is exceptional in that the only proof we know proceeds via Pstragowski's category of synthetic spectra. This was the final unresolved hidden 2-extension in the Adams spectral sequence through dimension 80. We hope this provides a concise demonstration of the computational leverage provided by $\mathbb{F}_2$-synthetic spectra.

description: The 2^{n} different n-point functions that occur in real-time thermal field theory are Fourier transformed to real energies. Because of branch cuts in various energy variables, none of these functions can be extended analytically to complex energies. The known linear combinations that form the fully retarded and advanced functions can be extended analytically. It is proven that no other linear combinations have an analytic extension to complex energies.

Current relaxation in the Random Resistor cum Tunneling Network Model through First-Passage route : Regimes and Time-scales

description: Numerically we study the bulk current relaxation in percolative Random Resistor cum Tunneling Network (RRTN) model through a first-passage route. The RRTN considers an extra semi-classical barrier-crossing process over a voltage threshold within a framework of classical RRN bond percolation model. We identify the different temporal regimes of relaxation and corresponding phenomenological time-scales, which fix up the extents of different regimes. These time-scales were previously identified in refs. \cite{relax-physicaA, aksubh}. We investigate on the distributions of these time-scales and observe that there exists a perfect correlation among them in the thermodynamic limit. We conclude that there exists a single time-scale which controls the RRTN dynamics. The variation of mean first-passage time .vs. system size seems to be due to sub-diffusive motion of charge carrier through the network.

description: Traffic is constrained by the information involved in locating the receiver and the physical distance between sender and receiver. We here focus on the former, and investigate traffic in the perspective of information handling. We re-plot the road map of cities in terms of the information needed to locate specific addresses and create information city networks with roads mapped to nodes and intersections to links between nodes. These networks have the broad degree distribution found in many other complex networks. The mapping to an information city network makes it possible to quantify the information associated with locating specific addresses.

description: Using an expected mean-variance model the changes in farm enterprise levels and indirect utility were examined under conditions of risk aversion, budget constraints and gross margin variance. An extension of the comparative statics of the expected mean-variance model was adopted by introducing a budget constraint into the constrained optimisation problem. A 10-year expected mean-variance whole-farm model was solved for a farm in the wheat-sheep zone of Australia to provide an empirical example. Results were obtained using no planning horizon (the static model) and then with a five-year rolling planning horizon (the dynamic model). In addition, enterprise levels were constrained to match levels observed on the farm so as to compare incomes between the constrained and unconstrained models. For a cash constrained, risk averse, farmer it was found that they are likely to have larger expenditures than less risk averse operators in order to obtain the same indirect utility. Enterprise levels differed between the dynamic and static models, and a dynamic model was used to help explain inter-temporal decision-making. Risk aversion reduced the set of possible welfare improving production activities available to a farmer.
The dynamics of liquid films, as described by the diffuse-interface model

description: The dynamics of a thin layer of liquid, between a flat solid substrate and an infinitely-thick layer of saturated vapor, is examined. The liquid and vapor are two phases of the same fluid, governed by the diffuse-interface model. The substrate is maintained at a fixed temperature, but in the bulk of the fluid the temperature is allowed to vary. The slope $\varepsilon$ of the liquid/vapor interface is assumed to be small, as is the ratio of its thickness to that of the film. Three asymptotic regimes are identified, depending on the vapor-to-liquid density ratio $ρ_{v}/ρ_{l}$. If $ρ_{v}/ρ_{l}\sim1$ (which implies that the temperature is comparable, but not necessarily close, to the critical value), the evolution of the interface is driven by the vertical flow due to liquid/vapor phase transition, with the horizontal flow being negligible. In the limit $ρ_{v}/ρ_{l}\rightarrow0$, it is the other way around, and there exists an intermediate regime, $ρ_{v}/ρ_{l}\sim\varepsilon^{4/3}$, where the two effects are of the same order. Only the $ρ_{v}/ρ_{l}\rightarrow0$ limit is mathematically similar to the case of incompressible (Navier--Stokes) liquids, whereas the asymptotic equations governing the other two regimes are of different types.
Jet quenching in relativistic heavy ion collisions

description: Parton propagation in dense nuclear matter results in elastic, inelastic and coherent multiple soft scattering with the in-medium color charges. Such scattering leads to calculable modifications of the hadron production cross section that is evaluated in the framework of the perturbative QCD factorization approach. Final state medium-induced gluon bremsstrahlung is arguably the most efficient way of suppressing large transverse momentum particle production in nucleus-nucleus collisions. The observed hadronic attenuation, known as jet quenching, can be related to the properties of the medium, such as density and temperature, and carries valuable information about the early stages of heavy ion reactions. Non-Abelian energy loss in the quark-gluon plasma can be studied in much greater detail through the modification of the two particle back-to-back correlations. Perturbative calculations give good description of the redistribution of the lost energy in lower transverse momentum particles and predict significant increase of the correlation width of away-side di-hadrons. In contrast, energy loss in cold nuclear matter was found to be small but for large values of Feynman-x is expected to complement the dynamical higher twist shadowing in experimentally observable forward rapidity hadron suppression.

description: The Australian government has identified soil carbon sequestration on agricultural lands as a potential strategy to offset greenhouse gas emissions. Industry and government claim providing positive incentives for farmers to change their land management will be cost can result in significant carbon sequestration in agricultural soils. There is, however, little information about the costs or benefits of agricultural soil carbon sequestration to test these claims. The objective of this study is to assess the costs of alternative land-use and land practises that will increase soil carbon sequestration, for a case study of the WA Wheat belt. The analysis integrates biophysical modelling of carbon sequestration with whole-farm economic modelling, to evaluate the cost-effectiveness of alternative carbon storage practices. Preliminary results suggest that, even under low commodity price scenarios, the opportunit sequestering carbon are considerable. We discuss the implications of our findings for policy development.

description: We demonstrate detection of NMR signals using a non-cryogenic atomic magnetometer and describe several novel applications of this technique. A water free induction decay (FID) signal in a 0.5 $μ$T field is detected using a spin-exchange-relaxation-free K magnetometer and the possibility of using a multi-channel magnetometer for 3-D MRI requiring only a single FID signal is described. We also demonstrate detection of less than $10^{13}$ $^{129}$Xe atoms whose NMR signal is enhanced by a factor of 540 due to Fermi-contact interaction with K atoms. This technique allows detection of less than $10^{9}$ $^{129}$Xe spins in a flowing system suitable for remote NMR applications.
