description: The PANDA experiment at the international accelerator Facility for Antiproton and Ion Research in Europe (FAIR), Darmstadt, Germany, will address fundamental questions of hadron physics using $\bar{p}p$ annihilations. Excellent Particle Identification (PID) over a large range of solid angles and particle momenta will be essential to meet the objectives of the rich physics program. Charged PID in the target region will be provided by a Barrel DIRC (Detection of Internally Reflected Cherenkov light) counter. The Barrel DIRC, covering the polar angle range of 22-140 degrees, will provide a $π/K$ separation power of at least 3 standard deviations for charged particle momenta up to 3.5 GeV/c. The design of the Barrel DIRC features narrow radiator bars made from synthetic fused silica, an innovative multi-layer spherical lens focusing system, a prism-shaped synthetic fused silica expansion volume, and an array of lifetime-enhanced Microchannel Plate PMTs (MCP-PMTs) to detect the hit location and arrival time of the Cherenkov photons. Detailed Monte-Carlo simulations were performed, and reconstruction methods were developed to study the performance of the system. All critical aspects of the design and the performance were validated with system prototypes in a mixed hadron beam at the CERN PS. In 2020 the PANDA Barrel DIRC project advanced from the design stage to component fabrication. The series production of the fused silica bars was successfully completed in 2021 and delivery of the MCP-PMTs started in May 2022.

description: Recreational anglers are known to seek different types of experiences in different settings. Such preference and behavioural diversity has important management implications. Research methods which assume only a limited degree of preference heterogeneity and impose rigid substitution patterns can impair understanding of individual’s unique decision process and lead to misguided management and policy recommendations. This paper reports results from an internet-based stated preference survey of recreational trout anglers in the North Canterbury Region of New Zealand. A mixed logit model, which simultaneously specifies random parameters plus error components, is used to capture the extent of random preference heterogeneity in systematic utility along with variance differences in unobserved utility at the alternative specific level. These error components are independent of the random parameters and fully relax the IID property. The model is further generalised to control for heterogeneity in the means and heteroscedasticity in the variances of the random parameters as well as error components using angler’s self reported skill level. The performance of the extended mixed logit-error component specification is evaluated against multinomial logit and latent class.
Indentification and characterization of a prostate-specific androgen independent protein binding site in the probasin promoter
Creators: name: Yeung, Lillian Hoi Yan
Publisher: name: University of British Columbia
Year: 2009

description: It is known that the probasin (PB) promoter has the ability to dictate prostatespecific gene expression both in vitro and in vivo. Unfortunately, the regulatory factors that dictate the prostate-tissue specific gene expression are currently unknown. In this study we investigated the combination of transcription factors and proteins binding to the proximal part of the PB promoter. Using DNasel and DMS in vitro footprinting, several protected regions were identified on the proximal PB promoter (nucleotides -286 to +28 relative to the transcription start site) when nuclear extracts from LNCaP, a human prostate cancer cell line, were used. Three of the protected areas were observed only when LNCaP nuclear extracts treated with synthetic androgen (10nM R1881) were used. Two other regions, referred to as FPI and FPII, showed protection regardless of presence or absence of androgen. When DNaseI footprinting was done using other prostate and non-prostate nuclear extracts, protection of the FPII region was only seen in prostate cell lines. These androgen-independent regions were further tested for tissue and binding specificity using the electrophoresis mobility shift assay (EMSA). Eight complexes formed with the FPI probe while four complexes were observed with the FPII probe on incubation with the tested nuclear extracts. Methylation protection assays reveal that prostate cancer cell lines yield subtly different protection patterns for some of the protein complexes formed with non-prostate derived cell lines, suggesting the presence of prostate-enriched or -exclusive proteins. In an attempt to identify the protein(s) binding to the FPII region, transcription factor database searches were used. Two potential candidates, c-Myb and NF-I, were identified. Binding assays, including supershift experiments revealed the participation of NF-I or a closely related protein, although other unknown proteins are also involved. In transient transfection studies, site directed mutagenesis of the putative NF-I site within FPII resulted in a significant reduction in PB promoter activity compared to the wild type promoter. Defining the DNA and protein components that dictate prostate-specific expression of the probasin promoter in an androgen-independent manner would provide a strong basis for the design and development of a gene therapy for systemic treatment of androgen independent prostate cancer.
Two-particle correlations on transverse momentum and momentum dissipation in Au-Au collisions at $\sqrt{s_{NN}}$ = 130 GeV

description: Measurements of two-particle correlations on transverse momentum $p_t$ for Au-Au collisions at $\sqrt{s_{NN}} = 130$ GeV are presented. Significant large-momentum-scale correlations are observed for charged primary hadrons with $0.15 \leq p_t \leq 2$ GeV/$c$ and pseudorapidity $|η| \leq 1.3$. Such correlations were not observed in a similar study at lower energy and are not predicted by theoretical collision models. Their direct relation to mean-$p_t$ fluctuations measured in the same angular acceptance is demonstrated. Positive correlations are observed for pairs of particles which have large $p_t$ values while negative correlations occur for pairs in which one particle has large $p_t$ and the other has much lower $p_t$. The correlation amplitudes per final state particle increase with collision centrality. The observed correlations are consistent with a scenario in which the transverse momentum of hadrons associated with initial-stage semi-hard parton scattering is dissipated by the medium to lower $p_t$.

description: The welfare costs of urban water restrictions are now well recognised, even if not yet quantified with precision (see, for example, Edwards 2008). Notwithstanding the costs that attend this form of intervention, governments have proven reluctant to abandon them, at least until additional infrastructure is in place. Accordingly, some form of behavioural constraint over the use of water is now applied in almost every major urban centre in Australia. Against this background there is value in understanding the motivations for individuals to comply with water restrictions. There is also much to be gained from developing an appreciation of the preferences for different restriction regimes. There is also scope to address wider politico-economic considerations as part of this analysis. This paper considers some of these issues by presenting the results of a choice modelling and contingent valuation study drawing data from New South Wales and Victoria. The study also embodies data from water-rich and water-poor communities in metropolitan and regional settings.

description: We present Spitzer Space Telescope observations of the z=2.38 lya-emitter over-density associated with galaxy cluster J2143-4423, the largest known structure (110 Mpc) above z=2. We imaged 22 of the 37 known lya-emitters within the filament-like structure, using the MIPS 24um band. We detected 6 of the lya-emitters, including 3 of the 4 clouds of extended (>50 kpc) lyman alpha emission, also known as Lya Blobs. Conversion from rest-wavelength 7um to total far-infrared luminosity using locally derived correlations suggests all the detected sources are in the class of ULIRGs, with some reaching Hyper-LIRG energies. Lya blobs frequently show evidence for interaction, either in HST imaging, or the proximity of multiple MIPS sources within the Lya cloud. This connection suggests that interaction or even mergers may be related to the production of Lya blobs. A connection to mergers does not in itself help explain the origin of the Lya blobs, as most of the suggested mechanisms for creating Lya blobs (starbursts, AGN, cooling flows) could also be associated with galaxy interactions.

description: The terms ‘grandfather clause’ and ‘grandfathering’ describe elements of a policy program in which existing participants in an activity are protected from the impact of regulations, restrictions or charges applied to new entrants. In this paper, the role of grandfathering in the design of a carbon emissions trading scheme in Australia is assessed. It is argued that adjustment assistance policies such as those adopted in conjunction with previous microeconomic reform programs are preferable to policies based on the free issue of emissions permits.

subject: sensory attributes and cooking methods.

description: In modelling retail meat demand and supply equations it is difficult to identify close substitutes or competing products. However, close substitutes can be identified through a comparison of meat attributes, especially cooking method and sensory attributes. The Meat Standards Australia (MSA) grading system can be used to identify primals (whole muscles) with similar attributes. The MSA system is based on carcase attributes, cooking methods and sensory properties and it allocates 3, 4 or 5 stars to beef primals. Prices for different star grades are affected by the quantity of meat allocated into each grade and this is determined by cooking method, which is dependent upon season. Estimating demand and supply by MSA grades and cooking methods requires fewer variables and therefore reduces multicollinearity and increases model efficiency.

The key idea is to use peak sections to suitably localize the Hilbert spaces $H^{0}\left(X,L^{\otimes m}\right)$ around $z_{0}$ in the large volume limit.

description: In this study, we introduce a novel ansatz for Generalized Parton Distributions (GPDs), named GSAMA24. This ansatz aims to provide a more accurate and comprehensive description of the internal structure of hadrons by incorporating advanced parameterizations and fitting techniques. We compare the performance of the GSAMA24 ansatz with three established models: the Extended Regge (ER), Modified Gaussian (MG), and M-HS22 ansatz. The GSAMA24 ansatz is designed to address limitations observed in previous models by offering improved flexibility in the ( $t$ )-dependence and skewness parameter $ξ$. Our analysis involves fitting the GSAMA24 ansatz to experimental form factor data and evaluating its predictive power against the ER, MG, and M-HS22 models. The comparison is based on key metrics such as the accuracy of form factor predictions, the consistency with known GPD properties, and the computational efficiency of the fitting process. Results indicate that the GSAMA24 ansatz provides a superior fit to the experimental data, particularly in the high momentum transfer region, where it outperforms the ER and MG models. Additionally, the GSAMA24 ansatz demonstrates better agreement with the theoretical expectations of GPD behavior compared to the M-HS22 model. These findings suggest that the GSAMA24 ansatz is a promising tool for future studies of hadronic structure and could significantly enhance our understanding of the spatial and momentum distributions of quarks and gluons within hadrons.

Instanton-Induced Correlations in Hadrons

description: QCD instantons generate non-perturbative spin- and flavor- dependent forces between quarks. We review the results of a series of studies on instanton-induced correlations in hadrons. We first present some evidence for instanton-mediated interactions in QCD, based on lattice simulations. Then we show that the Instanton Liquid Model can reproduce the available data on proton and pion form factors at large momentum transfer and explain the delay of the onset of the perturbative regime in several hard reactions. We also show that instantons generate a deeply bound scalar color anti-triplet diquark, with a mass of about 450 MeV and size comparable with that of the proton. The strong attraction in the anti-triplet scalar diquark channel leads to a quantitative description of non-leptonic weak decays of hyperons and provides a microscopic dynamical explanation of the Delta I=1/2 rule.

description: Metropolis-Hastings (MH) is a commonly-used MCMC algorithm, but it can be intractable on large datasets due to requiring computations over the whole dataset. In this paper, we study minibatch MH methods, which instead use subsamples to enable scaling. We observe that most existing minibatch MH methods are inexact (i.e. they may change the target distribution), and show that this inexactness can cause arbitrarily large errors in inference. We propose a new exact minibatch MH method, TunaMH, which exposes a tunable trade-off between its batch size and its theoretically guaranteed convergence rate. We prove a lower bound on the batch size that any minibatch MH method must use to retain exactness while guaranteeing fast convergence-the first such bound for minibatch MH-and show TunaMH is asymptotically optimal in terms of the batch size. Empirically, we show TunaMH outperforms other exact minibatch MH methods on robust linear regression, truncated Gaussian mixtures, and logistic regression.

description: Despite reforms over the past quarter-century, world agricultural markets remain highly distorted by government policies. Traditional indicators of those price distortions such as the nominal rate of assistance and consumer tax equivalent provide measures of the degree of intervention, but they can be misleading as indicators of the true effects of those policies. By drawing on recent theoretical literature that provides indicators of the trade- and welfare-reducing effects of price and trade policies, this paper develops more-satisfactory indexes for capturing distortions to agricultural incentives. It then exploits the Agricultural Distortion database recently compiled by the World Bank to generate estimates of them for both developing and high-income countries over the past half century, based on a sample of 75 countries that together account for all but one-tenth of the world’s population, GDP and agricultural production. While they are still only partial equilibrium measures, they provide a much better approximation of the true trade and welfare effects of sectoral policies without needing a formal model of global markets or even price elasticity estimates.

Year: 2020
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In this paper, we explore the evolution of baryon asymmetry as well as the hypermagnetic field in the early universe with an assumption that the flavon of the Froggatt-Nielsen carries an asymmetry. Through the decay of the flavon to Standard Model fermions, this asymmetry is transferred to fermions, where the right-handed electron keeps its asymmetry while its Yukawa interaction is out of thermal equilibrium. Through the existence of the flavon, we can ensure that the freezing-in temperature of the right-handed electron is closer to the electroweak phase transition than the Standard cosmology scenario. With this trick, the asymmetry in the right-handed electron is saved for a longer time. Moreover, the injection of the asymmetry to the right-handed electron is gradual, which helps the preservation of the asymmetry in the right-handed sector significantly. Due to the intimate relationship between fermion number violation and the helicity of the hypermagnetic field, some of the asymmetry is used to amplify the hypermagnetic field which itself helps to preserve the remnant asymmetry through keeping the Yukawa processes out of thermal equilibrium. We find the sweet region of the parameter space that can produce the right asymmetry in the baryons while generating a large hypermagnetic field by the time of the electroweak phase transition.

Terroir rising? Varietal and quality distinctiveness of Australia’s wine regions

Publisher: name: Unknown
Year: 2009

description: It has been argued that part of the reason Australia was able to contribute to and respond so successfully in the 1990s to the growth in demand for commercial bottled wine was because of its freedom (relative to European producers) to blend wines across the full range of varieties and geographic regions, so as to be able to reproduce year after year a consistent style for each label. Over time, however, that has led some buyers in the ‘Old World’ to believe Australian and other ‘New World’ winemakers do not respect or exploit regional differences in terroir or, worse still, that the ‘New World’ is incapable of making high-quality, regionally distinct wines. This paper examines the changing extent to which Australian wine regions do in fact vary in their choice of winegrape varieties and in the average quality of those winegrapes. In doing so the study provides some new quantitative indexes that may be helpful for other purposes too, such as providing a base for simulating the potential impacts on different regions of climate change and of adaptive responses to it. The study focuses on 30 of Australia’s winegrape regions and on the top 12 red and 10 white winegrape varieties that together accounted in 2006 for all but 7 percent of Australia’s wine. It compares 2006 with 2001, the first year for which price and quantity data were compiled nationally by grape variety for the country’s newly defined Geographical Indication regions.

description: To obtain market access for NZ food exports to high value developed country markets exporters are having to comply and consider environmental factors such as carbon footprinting. This growth in demand for environmental attributes is shown in the rise of the food miles debate or concept. Food miles is a concept which has gained traction with the popular press arguing that the further food travels the more energy is used and therefore carbons emissions are greater. This paper assesses, using the same methodology, whether this is the case by comparing NZ production shipped to the UK with a UK source. The study found that due to the different production systems even when shipping was accounted for NZ dairy products used half the energy of their UK counterpart and in the case of lamb a quarter of the energy. In the case of apples the NZ source was 10 per cent more energy efficient. In case of onions whilst NZ used slightly more energy in production the energy cost of shipping was less than the cost of storage in the UK making NZ onions more energy efficient overall. The paper then explores other developments in market access to developed markets especially the rise in demand for products to be carbon footprinted and the introduction of carbon labelling. A review of latest methodology in carbon footprinting the PAS from the UK is reviewed and implications for trade assessed.

description: Communal water storage reservoirs (embungs) that serve many villages in West Timor, Indonesia, by providing water during the prolonged annual dry season are experiencing severe sedimentation problems. Sedimentation of reservoirs progressively reduces their water storage capacity and the benefits to community. This paper investigates four alternative strategies for managing the sedimentation of a typical village embung: (1) current management (a “no management” situation), (2) soil conservation in the embung catchment, (3) periodic sediment removal and (4) both soil conservation and sediment removal. Without periodic sediment removal, an embung has a finite life dependent on the rate of sedimentation. The results indicate that periodic cleaning is clearly worthwhile. Strategy (4) gives the highest NPV. Strategy (3) was not as good, though towards the upper end of the range of reasonable discount rates, it was almost as good as strategy 4. No management is the worst strategy.

description: Tiny values for gauge couplings of dark photons allow to suppress their kinetic mixing with ordinary photons. We point out that the Weak Gravity Conjecture predicts consequently low ultraviolet cut-offs where new degrees of freedom might appear. In particular, a mixing angle of $\mathcal{O}(10^{-15})$, required in order to fit the excess reported by XENON1T, corresponds to new physics below $\mathcal{O}(100)$ TeV, thus accessible at a Future Circular Collider. We show that possible realizations are provided by compactifications with six large extra dimensions and a string scale of order $\mathcal{O}(100)$ TeV.

description: Representing graph data in a low-dimensional space for subsequent tasks is the purpose of attributed graph embedding. Most existing neural network approaches learn latent representations by minimizing reconstruction errors. Rare work considers the data distribution and the topological structure of latent codes simultaneously, which often results in inferior embeddings in real-world graph data. This paper proposes a novel Deep Manifold (Variational) Graph Auto-Encoder (DMVGAE/DMGAE) method for attributed graph data to improve the stability and quality of learned representations to tackle the crowding problem. The node-to-node geodesic similarity is preserved between the original and latent space under a pre-defined distribution. The proposed method surpasses state-of-the-art baseline algorithms by a significant margin on different downstream tasks across popular datasets, which validates our solutions. We promise to release the code after acceptance.

description: As water resources in arid regions decline, agricultural producers are encouraged to adopt water conserving strategies. The implementation of alternative low-water use crops is one option, but is it economically feasible? Data on current and alternative crops for this study include enterprise budgets, producer interviews, and field trials in Northwestern Nevada, USA. We use WinEPIC, a Windows-based version of the EPIC model, which synthesizes both agronomics and economics, to model yields and returns of alternative crop production under differing irrigation levels. Risk analysis or the distribution of net returns to alternative crop production is also examined. This study determined that there are alternative crops that could be feasibly substituted for alfalfa and reduce water use by at least one-half while providing net returns that meet or exceed returns from alfalfa and keep producers profitable in agriculture

description: Food system dynamics worldwide are under a new paradigm. Energy supply based on renewable natural resources is now a necessary solution, where agri-business can play an important role, and food systems will have to interact worldwide with new competitors for land and agriculture activity. The argument in this paper is based on the evidence that innovation and technology changes in food production (agricultural production) can offer a sustainable supply of grain and biomass, when demand behaviour is consistent and very flexible (demand elasticity above 1). The main argument is based on the hypothesis that demand behaviour is the main driver in food systems, which can be observed looking at technical and technological changes in production systems in Europe and elsewhere, such as Latin America, and more specifically Brazil. Economic surplus distribution across the food chain is another key factor for the induced innovation process to occur dynamically in food and agricultural production, based on well functioning markets such as the international markets (elastic demand for most countries). Science will face a new industry demand for solutions on the production side that are able to provide sustainability and supply increases that have to support empowerment of the primary sector to help producers capture surplus created by new technology possibilities, and “new demands”. Technological changes will occur quickly enough to avoid strong changes in prices if, and only if, producers are able to look at new opportunities with conditions (and sufficient time) to improve their business (and share on economic surplus). Institutional innovation is another key factor in the food system, and should also provide capability to create value to a set of intangible goods provided by the primary sector, giving space for a multi-functionality perspective on the primary sector activity, such as environment and sustainability considerations. The first factor to be considered is certainly the market functioning, because food production traditionally suffers from market problems, which began with the characteristics of the products, space diversity, conservation problems, and production seasonality (to mention only the most obvious). Other considerations related with the environment, and non tangible goods, such as the landscape dimension (and other dimensions on man’s relationship with nature), will continue to deserve new initiatives to improve the Quality of Life.

At microscopic scales, an important challenge lies in overpowering the particles reorientation due to thermal fluctuations, especially in nano-sized systems, to create non-random, directed motion, needed for a wide range of possible applications. In this article, we employ molecular dynamics simulations to show that the diffusion of a self-propelling dipolar nanocube can be enhanced in a pre-defined direction with the help of a moderately strong applied magnetic field, overruling the effect of the thermal fluctuations. Furthermore, we show that the direction of diffusion is given by the orientation of the net internal magnetisation of the cube. This can be used to determine experimentally the latter in synthetically crafted active cobalt ferrite nanocubes.

A two-dimensional high-order well-balanced scheme for the shallow water equations with topography and Manning friction

description: We develop a two-dimensional high-order numerical scheme that exactly preserves and captures the moving steady states of the shallow water equations with topography or Manning friction. The high-order accuracy relies on a suitable polynomial reconstruction, while the well-balancedness property is based on the first-order scheme from Michel-Dansac et. al., 2016 and Michel-Dansac et. al., 2017, extended to two space dimensions. To get both properties, we use a convex combination between the high-order scheme and the first-order well-balanced scheme. By adequately choosing the convex combination parameter following a very simple steady state detector, we ensure that the resulting scheme is both high-order accurate and well-balanced. The method is then supplemented with a MOOD procedure to eliminate the spurious oscillations coming from the high-order polynomial reconstruction and to guarantee the physical admissibility of the solution. Numerical experiments show that the scheme indeed possesses the claimed properties. The simulation of the 2011 Japan tsunami, on real data, further confirms the relevance of this technique.
The species-area relationship and evolution

description: Models relating to the Species-Area curve are usually defined at the species level, and concerned only with ecological timescales. We examine an individual-based model of co-evolution on a spatial lattice based on the Tangled Nature model, and show that reproduction, mutation and dispersion by diffusion in an interacting system produces power-law Species-Area Relations as observed in ecological measurements at medium scales. We find that co-evolutionary habitats form, allowing high diversity levels in a spatially homogenous system, and these are maintained for exponentially increasing time when increasing system size.

description: One of the critical success factors for the future development of the agri-food sector is the increased integration of enterprises and other stakeholders in horizontal and vertical ‘communities’. Tracking and tracing, agreements on quality policy, improvements in logistics, dissemination of innovations, cooperation in quality planning and market orientation, access to knowledge bases, etc. are all examples which build on an increased horizontal or vertical integration in information and communication activities. The paper will discuss ongoing research on the conceptualization, design and testing of online communities that provide the functionalities that might improve cooperation in the different (horizontal and vertical) dimensions. It builds on initiatives from the area of ‘collaborative working environments’, sometimes captured under the heading ‘electronic community house’. First prototypes utilize freely available software modules and demonstrate the capability of today’s level of development if one has a clear conceptual base.

description: Two-level electron-phonon systems with reflection symmetry linearly coupled to one or two phonon modes (exciton and E$\otimes(b_1+b_2)$ Jahn-Teller model) exhibit strong enhancement of quantum fluctuations of the phonon coordinates and momenta due to the complex interplay of quantum fluctuations and nonlinearities inherent to the models. We show that for the complex correlated quantum fluctuations of the anisotropic two-level systems the Shannon entropies of phonon coordinate and momentum and their sum yield their proper global description. On the other hand, the variance measures of the Heisenberg uncertainties suffer from several shortcomings to provide proper description of the fluctuations. Wave functions, related entropies and variances were determined by direct numerical simulations. Illustrative variational calculations were performed to demonstrate the effect on an analytically tractable exciton model.

description: The goal of this paper is to frame the effect of regulatory burdens in a research outline which enables the study of their effect on the competitiveness of the food and drinks industry, especially the European dairy sector. A firm perspective is used. We address the basic structure and tendencies in the food sector, the regulatory role of regulatory burdens and their effect on competitiveness. A theoretical foundation is provided by transaction cost economics and total quality management insights. The effects of legislation on administrative costs and competitiveness are mediated by impacts on innovativeness, company strategy, food safety system availability, as well as the available information & communication capabilities. Building on a previous studies showing the negative impact of administrative requirements on competitiveness, this paper focuses at expanding the available research framework and to adjust it to sector (i.e. dairy) specifics. We will connect to previous research (Wijnands et al., 2007) which, among others, generated the following generic results: - administrative burdens are connected to prevention measures; - administrative burdens impede on the innovativeness of food companies; - administrative burdens are influenced by the content of law and by the predictability and clearness of regulations.
Latent dynamical variables produce signatures of spatiotemporal criticality in large biological systems

description: Understanding the activity of large populations of neurons is difficult due to the combinatorial complexity of possible cell-cell interactions. To reduce the complexity, coarse-graining had been previously applied to experimental neural recordings, which showed over two decades of scaling in free energy, activity variance, eigenvalue spectra, and correlation time, hinting that the mouse hippocampus operates in a critical regime. We model the experiment by simulating conditionally independent binary neurons coupled to a small number of long-timescale stochastic fields and then replicating the coarse-graining procedure and analysis. This reproduces the experimentally-observed scalings, suggesting that they may arise from coupling the neural population activity to latent dynamic stimuli. Further, parameter sweeps for our model suggest that emergence of scaling requires most of the cells in a population to couple to the latent stimuli, predicting that even the celebrated place cells must also respond to non-place stimuli.
