description: Despite the importance of the agricultural and downstream processing sectors in the New Zealand economy, there is no tradition of using partial or general equilibrium models to evaluate policies or other measures directed at the agricultural sector. Policy-makers have instead relied on the development of ad hoc scenarios of land use change, farm budget models, and simple multiplier analysis of flow-on effects. To redress this situation, we have developed a catchment-scale partial equilibrium framework based on the US REAP model, which we have thus far calibrated for two different catchments. In this paper, we present an application of the model to the Hurunui Catchment in North Canterbury in which we assess several scenarios for the development of irrigated area under several water storage options. This application is timely, given that there are increasing pressures on water resources in the catchment, and frequent conflicts between abstractive users (mainly pastoral), recreational users (e.g. kayaking, fishing) users, and environmental needs. Currently, a private consortium are pursuing storage options similar to those that we have modelled, while a newly constituted Water Management Zone Committee is tasked with developing a strategic approach to managing water in the Hurunui and adjacent Waiau catchments. In addition, water quality limits are also being developed in the Hurunui catchment. Our modelling approach includes pastoral (dairy, sheep, beef and deer), arable, horticultural and forestry enterprises along with an array of management including various irrigation and fertiliser regimes. The model allows us to test policy scenarios for addressing environmental issues such as mitigating climate change and improving water quality, and changes in resource constraints such as water availability. Using a profit maximizing objective function we compare the impact of the proposed irrigation scenarios in the Hurunui catchment on total catchment profits and a variety of environmental parameters like greenhouse gas emissions and nutrient losses.

Il n'a pas pour but de presenter un travail abouti, mais illustre le deploiement par un cas concret et ebauche une liste de besoins non encore satisfaits dans le domaine. ----- The J2EE (Java 2 platform Enterprise Edition) specification defines an architecture for Java Application Servers. Until J2EE 1.3, the deployment aspect was addressed from the developer point of view only. Since J2EE 1.4, deployment APIs and steps have been more precisely specified within the "J2EE Deployment Specification". JOnAS (Java Open Application Server) is a J2EE platform implementation by ObjectWeb. The deployment aspects are under development. This article describes the J2EE Deployment concepts, and the issues raised when implementing deployment features within JOnAS. It does not provide a complete solution, but illustrates deployment through a concrete example and initiates a list of non fulfilled requirements.
A model for the generic alpha relaxation of viscous liquids
Creators: name: Dyre, Jeppe C.
Publisher: name: arXiv
Year: 2005
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: Dielectric measurements on molecular liquids just above the glass transition indicate that alpha relaxation is characterized by a generic high-frequency loss varying as $ω^{-1/2}$, whereas deviations from this come from one or more low-lying beta processes [Olsen et al, Phys. Rev. Lett. {\bf 86} (2001) 1271]. Assuming that long-wavelength fluctuations dominate the dynamics, a model for the dielectric alpha relaxation based on the simplest coupling between the density and dipole density fields is proposed here. The model, which is solved in second order perturbation theory in the Gaussian approximation, reproduces the generic features of alpha relaxation.

description: This paper is motivated by applications of a Census Bureau interested in releasing aggregate socio-economic data about a large population without revealing sensitive information about any individual. The released information can be the number of individuals living alone, the number of cars they own, or their salary brackets. Recent events have identified some of the privacy challenges faced by these organizations. To address them, this paper presents a novel differential-privacy mechanism for releasing hierarchical counts of individuals. The counts are reported at multiple granularities (e.g., the national, state, and county levels) and must be consistent across all levels. The core of the mechanism is an optimization model that redistributes the noise introduced to achieve differential privacy in order to meet the consistency constraints between the hierarchical levels. The key technical contribution of the paper shows that this optimization problem can be solved in polynomial time by exploiting the structure of its cost functions. Experimental results on very large, real datasets show that the proposed mechanism provides improvements of up to two orders of magnitude in terms of computational efficiency and accuracy with respect to other state-of-the-art techniques.

description: Researchers have widely analysed the economic, managerial, social and psychological drivers of industry adoption of R&D outputs both in the international (e.g. Rogers 2003) and Australian context (e.g. Pannell et al. 2006). Many of these studies have mainly focused on the drivers of industry adoption of technical research, whose value - increasing productivity or decreasing costs within a firm's boundaries - is generally more tangibly perceived by the industry (Pralahad 1993). On the other hand, research has not focused on the drivers of industry adoption of R&D outputs stimulating market development, whose value - identifying and exploiting a market opportunity outside the boundaries of the firm - is usually more uncertain and difficult to be perceived (Pralahad 1993). At the same time, the industry uptake of research for market development is crucial in current agri-food systems, where companies increasingly need to be consumer-responsive in order to sustain their competitive advantage and survive. To attempt to start filling this gap, we explored the factors influencing industry adoption of R&D in marketing by taking a case-based grounded theory approach (Glaser and Strauss 1967; Eisenhardt 1989). Thirty-five market development projects conducted by the Australian Seafood Cooperative Research Centre, in collaboration with a number of industry and research partners, provided the instrumental cases for this study. Although limited to the seafood sector, by comparing and contrasting cases in sub-sectors with very different characteristics (oyster, wild prawn, rock lobster, abalone, tuna, salmon, finfish, sardines, barramundi) this study empirically explores factors related to 1) individual firms' characteristics and capabilities, 2) firms' organization within their industry and with external stakeholders 3) the project scope of the value proposition and industry engagement process. Results show that although individual firms' characteristics and the governance and structure of their industry associations influences the industry uptake, the scope of value proposition and the process of industry engagement are in determining industry uptake. In particular, the focus of consumer/market research, the timely communication among partners and the industry acquisition of market-sensing capabilities are three key elements influencing the industry uptake of the public market development research outputs.

We provide an asymptotic expansion of the eigenvalues $λ_n$ as $n\to+\infty$, and prove that for each {\it real} polynomial $P_{m-1}$, the eigenvalues are all real and positive, with only finitely many exceptions.

description: The SMPL body model is widely used for the estimation, synthesis, and analysis of 3D human pose and shape. While popular, we show that SMPL has several limitations and introduce STAR, which is quantitatively and qualitatively superior to SMPL. First, SMPL has a huge number of parameters resulting from its use of global blend shapes. These dense pose-corrective offsets relate every vertex on the mesh to all the joints in the kinematic tree, capturing spurious long-range correlations. To address this, we define per-joint pose correctives and learn the subset of mesh vertices that are influenced by each joint movement. This sparse formulation results in more realistic deformations and significantly reduces the number of model parameters to 20% of SMPL. When trained on the same data as SMPL, STAR generalizes better despite having many fewer parameters. Second, SMPL factors pose-dependent deformations from body shape while, in reality, people with different shapes deform differently. Consequently, we learn shape-dependent pose-corrective blend shapes that depend on both body pose and BMI. Third, we show that the shape space of SMPL is not rich enough to capture the variation in the human population. We address this by training STAR with an additional 10,000 scans of male and female subjects, and show that this results in better model generalization. STAR is compact, generalizes better to new bodies and is a drop-in replacement for SMPL. STAR is publicly available for research purposes at http://star.is.tue.mpg.de.

description: We show that Google search activity on relevant terms is a strong out-of-sample predictor for future employment growth in the US over the period 2004-2019 at both short and long horizons. Starting from an initial search term “jobs”, we construct a large panel of 172 variables using Google’s own algorithms to find semantically related search queries. The best Google Trends model achieves an out-of-sample R2 between 29% and 62% at horizons spanning from one month to one year ahead, strongly outperforming benchmarks based on a single search query or a large set of macroeconomic, financial, and sentiment predictors. This strong predictability is due to heterogeneity in search terms and extends to industry-level and state-level employment growth using state-level specific search activity. Encompassing tests indicate that when the Google Trends panel is exploited using a non-linear model, it fully encompasses the macroeconomic forecasts and provides significant information in excess of those.

description: A large number of empirical studies have recently explored the processes and the conditions under agri-food companies acquire and develop market orientation (e.g. Martin et al. 2009), entrepreneurship (e.g. Holster 2008) and innovation (e.g. Verhees 2005), which have been proven to have a positive relationship with their performance (e.g. Micheels and Gow 2008). A much smaller number of studies focused on how agri-food firms can acquire the capabilities that are necessary to become market-oriented and innovative (e.g. Anderson & Narus 2007), specifically market sensing and customer linking (Day 1994). As a number of public-private partnership projects are attempting to enhance agri-food companies' market orientation and innovation, it is useful to identify which research and dissemination methods effectively develop these capabilities and under which conditions. To attempt to start filling this gap, this study analyses under which conditions public-private projects based on research and dissemination manage to foster market-sensing and customer-linking capabilities of small agri-food firms. Fostering these capabilities in small firms is particularly challenging, as they have limited resources to absorb the new information, learn and apply strategic changes as a result of the learning process. The case of five knowledge-building Seafood Cooperative Research Centre projects based on supply chain mapping and benchmarking methods with the oyster, wild prawn, farmed prawn and finfish industries provides the instrumental cases to the study. We collected data both quantitatively and qualitatively to gain more insight on the cause-effect relationship among variables (Eisenhardt 1989). Then, we analysed data with a structural equation model, whose multivariate statistic approach allows a rigorous analysis of the relationships between latent variables such as market-sensing and customer-linking capabilities and attitudes. Preliminary results can be summarized as follows. First, an estimation of profit margins that different customers make along the chain and an assessment of customers' needs, when customers' concentration and rivalry along the chain is low, are crucial to foster small farms' capabilities. Second, informal networks play a key role for fostering these capabilities from few small firms to the majority of the target.

description: We optimize the turning on of a one-dimensional optical potential, V_L(x,t) = S(t) V_0 cos^2(kx) to obtain the optimal turn-on function S(t) so as to load a Bose-Einstein condensate into the ground state of the optical lattice of depth V_0. Specifically, we minimize interband excitations at the end of the turn-on of the optical potential at the final ramp time t_r, where S(t_r) = 1, given that S(0) = 0. Detailed numerical calculations confirm that a simple unit cell model is an excellent approximation when the turn-on time t_r is long compared with the inverse of the band excitation frequency and short in comparison with nonlinear time \hbar/μwhere μis the chemical potential of the condensate. We demonstrate using the Gross-Pitaevskii equation with an optimal turn-on function S(t) that the ground state of the optical lattice can be loaded with very little excitation even for times t_r on the order of the inverse band excitation frequency.

description: In recent years, renewable energy technologies have been advocated in Fiji on the basis that they improve energy security and serve as a risk-mitigation measure against oil price volatility. Despite this, there have been few attempts to measure the impact of renewable technologies on energy security. That analysis is important if the benefits of renewable energy technologies in Fiji are to be adequately evaluated. This paper develops and applies a method for assessing the potential contribution of renewable technologies to the security of electricity supply in Fiji. The method is based on an application of portfolio theory, traditionally used in financial markets, to the electricity generation mix in Fiji. The results demonstrate the impact of different renewable technologies on both portfolio generation cost and risk for Fijian electricity grids.

description: We study the problem of distributed estimation over adaptive networks where communication delays exist between nodes. In particular, we investigate the diffusion Least-Mean- Square (LMS) strategy where delayed intermediate estimates (due to the communication channels) are employed during the combination step. One important question is: Do the delays affect the stability condition and performance? To answer this question, we conduct a detailed performance analysis in the mean and in the mean-square-error sense of the diffusion LMS with delayed estimates. Stability conditions, transient and steady-state mean-square-deviation (MSD) expressions are provided. One of the main findings is that diffusion LMS with delays can still converge under the same step-sizes condition of the diffusion LMS without delays. Finally, simulation results illustrate the theoretical findings.

description: Pierce’s Disease (PD) is a bacterial disease that can kill grapevines over a span of one to three years. In this paper, we examine and model PD and vector control decisions made at the vineyard level in the Napa Valley in an effort to understand how the pest and disease affect individual growers, and to examine spatial externality issues and potential benefits from cooperation between adjacent vineyards. The model that we created adds to the literature by (a) treating grape vines as capital stocks that take time to reach bearing age and thus cannot be immediately replaced in the event of becoming diseased. We also (b) relax the assumption of an interior solution by examining the boundaries of parameter space for which winegrape growing is profitable and thus allowing growers to abandon land if it is not. We also explore (c) the effect of changing different policy parameters, such as PD control and vine replacement costs. Finally (d) we examine the potential benefits of cooperation between growers to manage vector populations, and determine that coordinated vector control could help riparian-adjacent growers to lessen grapevine losses and land abandonment, and thus to remain profitable in times of high PD pressure.

description: We present an efficient scheme for representing many-body wavefunctions in quantum Monte Carlo (QMC) calculations. The scheme is based on B-splines (blip functions), which consist of localized cubic splines centred on the points of a regular grid. We show that blip functions are unbiased, systematically improvable, and conveniently obtained from any standard plane-waves density functional theory (PW-DFT) code, and therefore provide a convenient and natural interface between PW-DFT and QMC calculations. We present tests on a 16-atom system of Si in the $β$-tin structure, and on 2- and 8- atoms systems of MgO in the NaCl structure. We show that already with such small systems the speed-up of blip functions with respect to plane-waves is between one and two order of magnitudes, without compromising the accuracy.

Evidence for new pulsation modes in Betelgeuse from BRITE data
Creators: name: Granzer, Thomas
Publisher: name: Zenodo
Year: 2024

description: In a recent paper, H. Saio et al. (MNRAS 526, 2765; 2023) claim that Betelgeuse may have reached the end of its core-carbon burning phase. Crucial here is the confirmation of a P~180d pulsation period. While some shallow evidence for an P~185d periodicity was claimed by Joyce at al. (ApJ 902, 63; 2020), this mode, as I will show in my talk, is undoubtedly present in BRITE-blue data. Nance et al. (MNRAS 479, 251; 2018) infer from models that, depending on the evolutionary stage of Betelgeuse, acoustic waves with periods P<20d may be generated in the convective core. While they doubt that any signal would penetrate to the surface, some recent 3D-modeling indicate a possible leakage of such frequencies to the surface. While less clear, I will also try to tackle this frequency range within the BRITE data set.

Multiple mechanisms of apoptosis induced by 20(S)-protopanaxadiol (aPPD) in glioma cells
Creators: name: Liu, Guo Yu
Publisher: name: University of British Columbia
Year: 2009

description: Ginsenosides are major pharmaceutical components in ginseng, cytotoxicity of ginsenoside Rh2, which exists in ginseng extract with trace concentrations, on cancer cells has been known. In our previous study, we identified that Careseng®, a specially formulated ginseng product, had the equal cytotoxicity on tumor cells as Rh2. In this study I investigated the mechanism of apoptosis in glioma cells with different PTEN and P53 status induced by 20(S) protopanaxadiol (aPPD), which is a derivative of Rh2 and the major constituent of Careseng®. aPPD can be obtained in lower cost from ginseng. Firstly, based on the viability analysis and DNA staining of U87MG (PTEN negative and wild type p53) and SF188 (PTEN positive and p53 mutant) cells treated by aPPD, it was found that aPPD, as effectively as Rh2, rapidly induced apoptosis in two glioma cell lines. The cell apoptosis of U87MG and SF188 cells induced by aPPD was confirmed by DNA fragmentation, TUNEL DNA-staining, typical apoptotic nuclear changes and cell membrane blebbing. By Western Blot analysis, it was demonstrated that caspase-3, -7, -8 and -9 were activated in the SF188 cells with dose- and time-response relationship to aPPD treatment but not in the U87MG cells, and found that cells with caspase activation revealed much more sensitive to aPPD treatment than those without caspase activation. Phosphorylated Akt on Ser473 was significantly decreased in U87MG but not SF188 cells. APPD-caused increase in intensity of superoxide anion and number of positive cells in both cell lines. Antioxidant gene activator, tBHQ or general caspase inhibitor partially blocked the aPPD-induced cell when applied alone but demonstrated a nearly complete protection when used together in SF188 cells. Although, INK phosphorylation was significantly increased in aPPD treated glioma cells, their activation was not related to the apoptosis as INK inhibitors had effect on the cell viability. The above results suggest that aPPD is a promising candidate for anti-cancer agent that induces apoptosis in a wide spectrum of cancer types. The bioactivity of aPPD is related to multiple signalling pathways and apoptosis induced by aPPD may be mediated by different mechanisms in different cells.

description: This work considers methods for imposing sparsity in Bayesian regression with applications in nonlinear system identification. We first review automatic relevance determination (ARD) and analytically demonstrate the need to additional regularization or thresholding to achieve sparse models. We then discuss two classes of methods, regularization based and thresholding based, which build on ARD to learn parsimonious solutions to linear problems. In the case of orthogonal covariates, we analytically demonstrate favorable performance with regards to learning a small set of active terms in a linear system with a sparse solution. Several example problems are presented to compare the set of proposed methods in terms of advantages and limitations to ARD in bases with hundreds of elements. The aim of this paper is to analyze and understand the assumptions that lead to several algorithms and to provide theoretical and empirical results so that the reader may gain insight and make more informed choices regarding sparse Bayesian regression.
Striking a balance between intense recreation and parks conservation in Victoria, BC : a study of Thetis Lake, Francis/King and Mill Hill regional parks
Creators: name: Lommerse, Julia Cathrina
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of many parks, particularly those that aim to preserve extensive natural areas is twofold. First, to protect the natural environment within the park boundaries and, secondly to provide the public with recreational opportunities. Often these two purposes clash in a dynamic growing community; such is the situation that exists for the parks case- studied for this thesis. Perhaps, in order to balance the dual and somewhat opposing mandates, a new paradigm or approach to park planning and design should be considered. One that seeks to balance the fragile and complex ecosystems found within parks and their connection to the regional environment, while recognizing the recreational pressure exerted by the community. Standard approaches to planning, engineering, and construction are often employed in various types and sizes of parks across Canada. As a result, infrastructure and facilities often create generic spaces, which seem out of context and character for the area. Park facilities, infrastructure and connections should ultimately protect fragile environments; respond to the ecology of the park and the character of the place. This thesis explores these dilemmas and seeks to provide an example of how a landscape ecology approach can be applied to three conservation parks—Thetis Lake, Francis/King and Mill Hill Regional Parks on southern Vancouver Island in the Capital Regional District. This area, which includes the capital city of Victoria, is experiencing rapid development. As a result, the three regional parks used as a case study for this thesis are facing the pressure of increased visitorship. Now that more recreational demands have been placed on the park the antiquated facilities, plus the fact that the park infrastructure and design was based on previous uses, have started to show their inadequacies. Essentially the parks' imageablility, recreational carrying capacity and ecology are the key components that are suffering. Perhaps an alternative approach to planning and design can enhance and contribute to the healthy ecological function of these parks, and at the same time meet the increased recreational demands and convey the image that these parks are essentially conservation parks.

description: One of the most crucial problems facing the U.S. economy is the possibility of a terrorist attack on its food sector. The implications can be profound for its stakeholders, who are highly dependent on this sector for their economic livelihood as well as their food supplies. The U.S. Bioterrorism Act of 2002 was enacted to improve the ability of the United States to prevent, prepare for and respond to bioterrorism and other public health emergencies. One of the important features of the U.S. Bioterrorism Act of 2002 is its emphasis on prevention, a change from prior legislation that focused on punishments after an incidence had occurred. The U.S. Bioterrorism Act does not address food safety issues in general; its focus is to prevent intentional contamination. The objective of this study was to assess the preparedness to potential bioterrorism in the grain and oilseed sector based on facility security expenditures and history of security breaches. The study was conducted as a research activity under the multistate project NC-1016 “Economic Assessment of Changes in Trade Arrangements, Bio-terrorism Threats and Renewable Fuels Requirements on the U.S. Grain and Oilseed Sector.” In addition to assessing preparedness, the study investigated the relationship between adoption of security measures and breaches in facility security. Finally the study documents, for a small sample, the extent to which grain and oilseed facilities appear to be following regulations that implement the U.S. Bioterrorism Act.

description: We revisit the Einstein-Gauss-Bonnet theory in view of the GW170817 event, which compels that the gravitational wave speed is equal to $c_T^2=1$ in natural units. We use an alternative approach compared to one previous work of ours, which enables us to express all the slow-roll indices and the observational indices as functions of the scalar field. Using our formalism we investigate if the Swampland criteria are satisfied for the Einstein-Gauss-Bonnet theory and as we demonstrate, the Swampland criteria are satisfied for quite general forms of the potential and the Gauss-Bonnet coupling function $ξ(ϕ)$, if the slow-roll conditions are assumed to hold true.

description: This paper proposes a software architecture for dynamical service adaptation. The services are constituted by reusable software components. The adaptation's goal is to optimize the service function of their execution context. For a first step, the context will take into account just the user needs but other elements will be added. A particular feature in our proposition is the profiles that are used not only to describe the context's elements but also the components itself. An Adapter analyzes the compatibility between all these profiles and detects the points where the profiles are not compatibles. The same Adapter search and apply the possible adaptation solutions: component customization, insertion, extraction or replacement.

description: Using estimation of demand for the George Washington/Jefferson National Forest as a case study, it is shown that in a stratified/clustered on-site sample, latent heterogeneity needs to be accounted for twice: first to account for dispersion in the data caused by unobservability of the process that results in low and high frequency visitors in the population, and second to capture unobservable heterogeneity among individuals surveyed at different sites according to a stratified random sample (site specific effects). It is shown that both of the parameters capturing latent heterogeneity are statistically significant. It is therefore claimed in this paper, that the model accounting for site-specific effects is superior to the model without such effects. Goodness of fit statistics show that our empirical model is superior to models that do not account for latent heterogeneity for the second time. The price coefficient for the travel cost variable changes across model resulting in differences in consumer surplus measures. The expected mean also changes across different models. This information is of importance to the USDA Forest Service for the purpose of consumer surplus calculations and projections for budget allocation and resource utilization.
Effects of Solar Activity on Taylor Scale and Correlation Scale in Solar Wind Magnetic Fluctuations

description: The correlation scale and the Taylor scale are evaluated for interplanetary magnetic field fluctuations from two-point, single time correlation function using the Advanced Composition Explorer (ACE), Wind, and Cluster spacecraft data during the time period from 2001 to 2017, which covers over an entire solar cycle. The correlation scale and the Taylor scale are respectively compared with the sunspot number to investigate the effects of solar activity on the structure of the plasma turbulence. Our studies show that the Taylor scale increases with the increasing sunspot number, which indicates that the Taylor scale is positively correlated with the energy cascade rate, and the correlation coefficient between the sunspot number and the Taylor scale is 0.92. However, these results are not consistent with the traditional knowledge in hydrodynamic dissipation theories. One possible explanation is that in the solar wind, the fluid approximation fails at the spatial scales near the dissipation ranges. Therefore, the traditional hydrodynamic turbulence theory is incomplete for describing the physical nature of the solar wind turbulence, especially at the spatial scales near the kinetic dissipation scales.

description: We investigate the properties of 1262 red giant stars with high photospheric abundances of lithium observed by the GALAH and \Ktwo-HERMES surveys, and discuss them in the context of proposed mechanisms for lithium enrichment and re-depletion in giant stars. We confirm that Li-rich giants are rare, making up only 1.2 per cent of our giant star sample. We use stellar parameters from the third public data release from the GALAH survey and a Bayesian isochrone analysis to divide the sample into first-ascent red giant branch and red clump stars, and confirm these classifications using asteroseismic data from \Ktwo. We find that red clump stars are 2.5 times as likely to be lithium-rich as red giant branch stars, in agreement with other recent work. The probability for a star to be lithium-rich is affected by a number of factors, though the causality in those correlations is not entirely clear. We show for the first time that primary and secondary red clump stars have distinctly different lithium enrichment patterns. The data set discussed here is large and heterogeneous in terms of evolutionary phase, metallicity, rotation rate and mass. We expect that if the various mechanisms that have been proposed for lithium enrichment in evolved stars are in fact active, they should all contribute to this sample of lithium-rich giants at some level.
