description: In this paper, an optimal output consensus problem is studied for discrete-time linear multiagent systems subject to external disturbances. Each agent is assigned with a local cost function which is known only to itself. Distributed protocols are to be designed to guarantee an output consensus for these high-order agents and meanwhile minimize the aggregate cost as the sum of these local costs. To overcome the difficulties brought by high-order dynamics and external disturbances, we develop an embedded design and constructively present a distributed rule to solve this problem. The proposed control includes three terms: an optimal signal generator under a directed information graph, an observer-based compensator to reject these disturbances, and a reference tracking controller for these linear agents. It is shown to solve the formulated problem with some mild assumptions. A numerical example is also provided to illustrate the effectiveness of our proposed distributed control laws.

description: An artifact for the paper "Partial Order Reduction for Reachability Games", accepted at CONCUR'19.

The source-code for the engine is found in the "verifypn-games.zip" file while the experiments and scripts to execute those are found in "reproducability.zip".

Code

The implementation reuses the general framework of partial order reduction applied in https://doi.org/10.1016/j.jlamp.2018.09.002

The core reduction algorithm is implemented in a (semantically equivalent and) efficient manner in  PetriEngine/ReducingSuccessorGenerator.cpp

Here the "prepare"-method implements the equivalent of the "St"-function of the paper (Algorithm 2), the "closure"-method implements the "Saturate"-function (Algorithm 3) and computeFinite, computeSCC, computeStaticCycles being responsible for the cycle-detection (Algorithm 1).

Repeatability

The repeatability-package is only available on Linux.

To run the experiments as per the paper, run:

./run_POR.sh games-243 ; ./run_NPOR.sh games-243

Outputs will be generated in the "outputs" folder, and a Tex-table can be outputted by

./extract.sh games-243

Notice that we have pre-populated the outputs-folder with the results reported in the paper.

The execution-scripts will NOT overwrite existing output files, and thus the outputs folder should be purged prior to a re-run of the experiments.

To use a different executor (for instance sbatch on a slurm-enabled cluster for concurrent execution of the experiments), the run-commands can be prefixed as such:

EXECUTOR=sbatch ./run_POR.sh games-243

The included binary is revision 243 of https://code.launchpad.net/~verifypn-cpn/verifypn/verifypn-games

To limit the memory-consumption of each experiment, modify "run.sh" and change the "ulimit" memory-bound to the desired value.

A "timeout"-command can also be added here to introduce a time-limit of the execution (we utilize slurm for this purpose).

Notice that we measure and report the computation time excluding parsing; i.e. we report the fix-point computation-time as computed by the engine directly.

description: This series of six reports entitled: "On-Farm Food Safety and Environmental Farm Plans: Identifying and Classifying Benefits and Costs" was initiated soon after the launch of the Agricultural Policy Framework (APF) in 2002. The APF recognized the importance of food safety and environmental concerns for the future growth of the agriculture and Agri-food sector. For this reason, Agriculture and Agri-Food Canada (AAFC) commissioned this series of reports to develop a conceptual framework to strengthen our understanding of the potential benefit and cost implications of On-farm Food Safety (OFFS) and Environmental Farm Plans (EFP) that were key components of the APF. The reports were prepared by a group of academics with extensive knowledge of the agriculture and Agri-food sector and issues related to food safety, traceability and the environment. The first report presents a summary of the findings in the five main reports in the series. The second report presents the conceptual framework that was developed to help identify qualitatively the potential benefits and costs that the various players in the agriculture and agri-food supply chain would face in implementing OFFS and EFP programs. The third report applies this framework to pork, the fourth, to beef, the fifth, to grains and the sixth, to dairy. In general, benefits and costs are divided into both demand and supply side effects. In addition, both public and private costs and benefits are considered, especially since they help indicate where a role for government might be required and where markets are not working as well as they might. Based on these preliminary qualitative assessments, the beef and pork sector have more to gain from HACCP-based OFFS and EFP initiatives, due to their ability to gain market share from marketing their products internationally, while the grains sector already benefits internationally from its high quality reputation and the dairy sector is restricted to produce only for the domestic market. However, more work is required in these areas to validate and quantify costs and benefits.

description: We experimentally demonstrate the entanglement can be created on two distant particles using separate state. We show that two data particles can share some entanglement while one ancilla particle always remains separable from them during the experimental evolution of the system. Our experiment can be viewed as a benchmark to illustrate the idea that no prior entanglement is necessary to create entanglement.

description: The agriculture and agri-food sector faces a number of challenges such as rapid technological change, increased competition and changes in consumer requirements. The sector therefore needs to adjust to keep up with the changes and become more competitive. This report provides information about the pork supply chain and highlights the structural changes that have occurred over time in the pork industry. The report uses tables, charts and figures to describe performance indicators and structural changes within the industry and shows that the Canadian pork supply chain is healthy, growing and export-oriented.

description: We present constraints on the existence of weakly interacting massive particles (WIMPs) from an 11 kg-day target exposure of the DAMIC experiment at the SNOLAB underground laboratory. The observed energy spectrum and spatial distribution of ionization events with electron-equivalent energies $>$200 eV$_{\rm ee}$ in the DAMIC CCDs are consistent with backgrounds from natural radioactivity. An excess of ionization events is observed above the analysis threshold of 50 eV$_{\rm ee}$. While the origin of this low-energy excess requires further investigation, our data exclude spin-independent WIMP-nucleon scattering cross sections $σ_{χ-n}$ as low as $3\times 10^{-41}$ cm$^2$ for WIMPs with masses $m_χ$ from 7 to 10 GeV$c^{-2}$ . These results are the strongest constraints from a silicon target on the existence of WIMPs with $m_χ$$

We then apply these results show how Brownian motion-like results are recovered, and how an Ornstein-Uhlenbeck process results within a totally deterministic framework. These results illustrate that the contamination of experimental data by "noise" may, under certain circumstances, be alternately interpreted as the signature of an underlying chaotic process.

description: The agri-food chain today is significantly different from that of twenty years ago. Changing consumer demands, knowledge intensive technology, North American integration and globalization have all contributed to the evolution of the different segments of the chain, which include input suppliers, agricultural producers, food processors, and food distributors. The purpose of the performance report series is to create a picture of the economic health of the entire agri-food chain and its various segments, and to identify the challenges and opportunities that they will face in the future. To get a full picture of each component's and the whole chain's economic health, these reports will measure economic performance from several different perspectives; profitability, competitiveness, investment, productivity, innovativeness, etc. Traceability is the process of tracking or tracing the flow of products through a supply chain. Traceability systems can vary from simple traceback systems to systems that provide identity preservation and quality assurance. This report examines the extent of traceability in the Canadian dairy processing industry. The authors use a mail survey and Principal Component Analysis to better understand the drivers, the challenges and the costs and benefits experienced by firms which have implemented traceability systems. The report finds that most dairy processing plants had implemented a system of product traceability and are able to trace forward and backwards.

description: Ultraviolet (UV) scattering on quantum crossbars (QCB) is an effective tool for probing QCB spectral properties, leading to excitation of QCB plasmon(s). Experimentally, such a process corresponds to sharp peaks in the frequency dependence of the differential scattering cross section. The peak frequency strongly depends on the direction of the scattered light. As a result, $1D\to 2D$ crossover can be observed in the scattering spectrum. It manifests itself as a splitting of single lines into multiplets (mostly doublets). The splitting magnitude increases with interaction in QCB crosses, while the peak amplitudes decrease with electron-electron interaction within a QCB constituent.

description: We investigate the problem of the predominance and survival of "weak" species in the context of the simplest generalization of the spatial stochastic rock-paper-scissors model to four species by considering models in which one, two, or three species have a reduced predation probability. We show, using lattice based spatial stochastic simulations with random initial conditions, that if only one of the four species has its probability reduced then the most abundant species is the prey of the "weakest" (assuming that the simulations are large enough for coexistence to prevail). Also, among the remaining cases, we present examples in which "weak" and "strong" species have similar average abundances and others in which either of them dominates -- the most abundant species being always a prey of a "weak" species with which it maintains a unidirectional predator-prey interaction. However, in contrast to the three-species model, we find no systematic difference in the global performance of "weak" and "strong" species, and we conjecture that the same result will hold if the number of species is further increased. We also determine the probability of single species survival and coexistence as a function of the lattice size, discussing its dependence on initial conditions and on the change to the dynamics of the model which results from the extinction of one of the species.

This report reviews the different red meat traceability systems that are in place around the world, and explores the question: 'What kind of a traceability system do Canadian consumers want in the red meat sector?' The authors use experimental auctions of beef and ham sandwiches to estimate consumers' willingness to pay for simple traceback systems, traceback systems that provide assurances of superior food safety production standards and traceback systems that provide assurances of humane animal treatment.
Schrödinger evolution of the Hawking state

description: A Schrödinger-picture description of the evolving quantum state of Hawking radiation is given, based on an ADM decomposition using time slicings that smoothly cross the horizon. This treatment avoids requiring a role for trans-planckian modes, which can be viewed as artifacts of Hawking's original calculation, and also supports arguments that radiation from black holes is produced in a "quantum atmosphere" with thickness comparable to the horizon size, rather than microscopically far from it. Particularly explicit formulas are given for the two-dimensional analog of the Schwarzschild geometry. This analysis is expected to generalize to other black holes, and to cosmology. The resulting quantum evolution also provides important background for investigating corrections to the Hawking process, as are necessary for restoring unitary evolution of black hole decay.

description: We present a Chandra study of 38 X-ray luminous clusters of galaxies in the ROSAT Brightest Cluster Sample (BCS) that lie at z~0.15-0.4. We find that the majority of clusters at moderate redshift generally have smooth, relaxed morphologies with some evidence for mild substructure perhaps indicative of recent minor merger activity. Using spatially-resolved spectral analyses, cool cores appear to still be common at these redshifts. At a radius of 50 kpc, we find that at least 55 per cent of the clusters in our sample exhibit signs of mild cooling [t(cool)<10 Gyr], while in the central bin at least 34 per cent demonstrate signs of strong cooling [t(cool)<2 Gyr]. These percentages are nearly identical to those found for luminous, low-redshift clusters of galaxies, suggesting little evolution in cluster cores since z~0.4 and that heating and cooling mechanisms may already have stabilised by this epoch. Comparing the central cooling times to central Halpha emission in BCS clusters, we find a strong correspondence between the detection of Halpha and central cooling time. (Abridged)

Aerodynamically-driven rupture of a liquid film by turbulent shear flow

description: The rupture of a liquid film due to co-flowing turbulent shear flows in the gas phase is studied using a volume-of-fluid method. To simulate this multiphase problem, we use a simplified numerical setup where the liquid film is 'sandwiched' between two fully developed boundary layers from a turbulent channel simulation. The film deforms and eventually ruptures within the shear zone created by the co-flows. This efficient setup allows systematic variation of physical parameters to gauge their role in the aerodynamically-driven deformation and rupture of a liquid film under fully developed sheared turbulence. The present work presents a detailed study of the developing pressure field over the deforming film and related aerodynamic effects, as previously suggested by other authors, in particular the role of the inviscid lift and drag forces. A cumulative lift force is introduced to capture the effect of the alternating pressure minima and maxima forming over the film which amplify and eventually rupture the film. A velocity scale derived from the lift-induced drag force reflects the state of the turbulent boundary layer over the film and collapses the temporal development of this cumulative lift force as well as the amplitude of film deformation with some success for the different film thicknesses and Reynolds numbers.

Therapeutic applications of ceramide lipids for apoptosis induction
Creators: name: Shabbits, Jennifer A.
Publisher: name: University of British Columbia
Year: 2009

description: The emerging role of ceramide lipids in apoptosis and an increased understanding of their involvement in multidrug resistance (MDR) has revealed new opportunities for manipulating ceramide levels in order to achieve specific therapeutic objectives. The research presented in this thesis focused on the relationship between ceramide, MDR and apoptosis. Direct and indirect approaches for modulating intracellular ceramide levels were investigated in an attempt to chemosensitize MDR tumors and induce apoptosis. Inhibition of pro-apoptotic ceramide conversion to its non-cytotoxic glucosylceramide metabolite was shown to sensitize two human MDR breast cancer cell lines to the cytotoxic effects of tubulin-binding chemotherapy drugs. Enhanced sensitization was correlated with increased ceramide, suggesting that therapeutic manipulations aimed at increasing endogenous ceramide should promote apoptosis. On the basis of these results, the feasibility of delivering therapeutic amounts of exogenous ceramides to cells was then investigated. After evaluating different chain length ceramides it was determined that synthetic C₆-ceramide was internalized and cytotoxic to cells whereas naturally occurring C₁₆-ceramide was neither internalized nor cytotoxic. This difference established the importance of intracellular delivery as a prerequisite to apoptosis induction by exogenous ceramides. Liposome-based delivery systems were then introduced in an attempt to overcome the limitations associated with intracellular delivery of natural ceramide. Physically stable liposomes containing up to 50 mole percent C₁₆-ceramide in the lipid bilayer were successfully formulated. These liposomes were internalized by J774 macrophage cells in vitro and induced apoptosis with similar potency to free C6-ceramide. In order to translate this encouraging data to an in vivo model it was first necessary to evaluate the behavior of these liposomes in the circulation. Pharmacokinetic studies demonstrated in vivo stability over 24 hours following iv bolus administration. The antitumor activity of these liposomes was then evaluated in the J774 ascites tumor model. Optimal antitumor activity was observed following intraperitoneal administration of C₁₆-ceramide liposomes on days 1, 5, and 9. This corresponded to a statistically significant increase in animal survival of 43.5% over non-ceramide control liposomes. Taken together, this research provides evidence for the rational design of ceramide-based liposomes as a novel approach for cancer chemotherapy.

description: An important indicator of the performance of any economy is the productivity and the connections between the labour market and the sectoral distribution of profit. Despite the restrictions inherent in the use of different concepts of productivity, Kaldor and Verdoorn have undertaken a serious verification of some relationship between production, employment and productivity, in an attempt to explain the dynamics of inter-regional and inter-sectoral economies, resulting in the designation of the so-called Kaldor-Verdoorn Law. The model for such a law asks questions about the relationship between the growth of labour productivity and product growth, throwing up scale indices of impact and return, in particular applicable to the industrial sector. The main theoretical bases of the model have been developed in this article, with empirical applications to the fields of GDP, employment and added value in the Brazilian economy, and the assertions maintained by Kaldor and Verdoorn in their estimates of the elasticities obtained have been proven. In general, an incipient alteration of the structure of sectoral employment was observed, except in the case of the service sector, which offered, on a scale of 1 – 100, a change of 31, and thus a labour market structure with a notable internal modification.

description: Summary

To gain an idea on the possibility to use the EuroFIR E-learning module in several institutes within an existing curriculum it has been decided to send a small set of relevant questions to the affiliated partners within the consortium.

At the end of 2009 the questionnaire (annex 2) was sent to a group of selected institutes: AUT, RUG, DTU, UHEL, TTZ, NKUA, AUA, UCC< BGU, UiO UVI, UGR, SLU, UL, US, ETHZ and IMR. Twelve responses were received and the answers have been summarised (annex 1).

Most of the partners found the e-learning module of interest to use in their courses in the education curriculum. Some gave also suggestions for further expansion of the module with to think of antioxidants or bioactive compounds. Even if the partners would not become a AISBL partner, some were willing to pay a fee for having access to the e-learning module in their educational programme.

description: The objective of this study was to analyze the average production functions and the frontiers production function to characterize the structure of the agricultural production technology. Using data of the agricultural census of 1995/96 regarding the mesorregião of the Triangulo Mineiro and Alto Paranaíba of the State of Minas Gerais the goal programming was used to calculate the parameters of the Cobb Douglas production functions. One of the main conclusions is the existence of significant differences in the level of productive efficiency and in the structure of the production technologies in this Mesorrregião, indicating the bias that is incurred when making decisions only based on the parameters of the average production function. Another important conclusion is the fact that the procedures adopted in this study, shows some evidence about the structural characteristics of the production technology offering better information for the decision makers.

description: This work aims at verifying the competitiveness of the Brazilian soybean in relation to European Union and the of Asia-Pacific Economic Cooperation (APEC) Forum. To do so, the Revealed Comparative Advantage Index (RCAI), and the Regional Orientation Index (ROI) were used. The findings show that Brazil has been presenting a positive Revealed Comparative Advantage Indexes on the considered period and these were increasing except during the years of 1995, 1996, 1999 and 2003. The reason of these drops off may be related to the high exchange rates between 1995 and 1998 and, due to variations in the Brazilian and World soybean exportations. The ROI result concerning the European Union indicates that the exports are concentrated to the block. Although, this rate was falling during the analyzed period, the soybean exports are increasing to the block. This may indicate that the soybean exports to other markets are proportionally increasing, more the to the European Union. The ROI analyses to APEC indicated that the exports are extra APEC orientated; however, countries like China and Japan, that are members of the block, are great importers of Brazilian soybean nowadays.

description: We present a new area law which is associated with the correlator of OPE blocks in higher dimensional conformal field theories (CFTs). The area law shows similar behaviour as black hole entropy or geometric entanglement entropy. It includes a leading term which is proportional to the area of the entanglement surface, and a logarithmic subleading term with degree $q$. We extract the UV cutoff independent coefficients and discuss various properties of the coefficients.

description: This paper has the main goal of analyzing and evaluating the structure and dynamics of the market from the exporting section of Brazilian chicken raising, from 1996 to 2004. Concentration rates were calculated in order to measure the market share which are dominated by the main companies. The dynamics of the sector position (turnover) was also checked. The reached results point that the sector concentration is higt, and great investments are necessary to the performance in the international market; the placement of the companies was changed mainly due to the ones which had lost positions compared to the first year. However, the concentration has decreased, and there is evidence that the market power hasn’t been used by the companies in a sense of reducing the consumers’ well being.

description: The success of the agricultural systems is affected by several social, cultural and economical variables, which can restrict or nurture the development of the agribusiness. In this context, agricultural managers search for ways to improve production efficiency. This effort comprises the improvement of the managerial activities and decision making process. This research aimed to build a risk analysis framework, using different scenarios of economical analysis of an animal husbandry firm. The data used was collected from a rotational grazing system for beef cattle. The results suggest that the profitability of the system is low, and some of the risk scenarios presented negative profitability.

description: We study a special sort of 2-dimensional extended Topological Quantum Field Theories (TQFTs) which we call open-closed TQFTs. These are defined on open-closed cobordisms by which we mean smooth compact oriented 2-manifolds with corners that have a particular global structure in order to model the smooth topology of open and closed string worldsheets. We show that the category of open-closed TQFTs is equivalent to the category of knowledgeable Frobenius algebras. A knowledgeable Frobenius algebra (A,C,i,i^*) consists of a symmetric Frobenius algebra A, a commutative Frobenius algebra C, and an algebra homomorphism i:C->A with dual i^*:A->C, subject to some conditions. This result is achieved by providing a generators and relations description of the category of open-closed cobordisms. In order to prove the sufficiency of our relations, we provide a normal form for such cobordisms which is characterized by topological invariants. Starting from an arbitrary such cobordism, we construct a sequence of moves (generalized handle slides and handle cancellations) which transforms the given cobordism into the normal form. Using the generators and relations description of the category of open-closed cobordisms, we show that it is equivalent to the symmetric monoidal category freely generated by a knowledgeable Frobenius algebra. Our formalism is then generalized to the context of open-closed cobordisms with labeled free boundary components, i.e. to open-closed string worldsheets with D-brane labels at their free boundaries.

description: This study, conducted along the year 2003, was held in the environment of a cement company plant located in the São Paulo State. That industry has used carbon black as predominant energetic source which besides resulting a huge emission of gases (CO and CO2) into the atmosphere, has been more expensive than some other alternatives of biomass sources. Taking into consideration the location of that plant, there was a large supply of available biomass to be used as alternative fuel for industrial ovens. Several biomasses were analyzed and it was concluded that the sugar cane bagasse and residues of wood (sawdust and woodchips) were the most appropriate alternatives to such an industry.

description: We present observational results for extragalactic radio sources with milliarcsecond components, obtained with the 600 meter ring radio telescope RATAN-600 from 1st to 22nd December, 1997. For each source, a six frequency broad band radio spectrum was obtained by observing simultaneously with an accuracy up to a minute at 1.4, 2.7, 3.9, 7.7, 13 and 31 cm. The observed list is selected from Preston et al. (1985) VLBI survey and contains all the sources in the declinations between -30deg and +43deg with a correlated flux density exceeding 0.1 Jy at 13 cm. The sample includes the majority of sources to be studied in the current VSOP survey and the future RadioAstron Space VLBI mission.

description: Belgrade, as administrative, economic and cultural centre of Republic of Serbia, covers total area of 3.224 km2. From this area, 69,1% is agricultural land, which represents fundamental base for establishment of agricultural production. Live stock breeding, on the territory of Belgrade city, as well as in entire Republic of Serbia, is the most important branch of agriculture. On observed territory animal products’ processing industry (dairies and slaughter houses) especially is developed. Because of that, increment of total live stock breeding production is of great importance for this territory. For growth of live stock breeding competitiveness, in this paper work concrete activities are suggested, such as specialization and increment of production intensity, accomplishment of better financial conditions, selection, accomplishment of better primary agricultural products purchase, etc. In this paper work also are considered and described necessary measures which have to be done by governmental institution, local communities, agro complex companies and family husbandries, with main goal to increase livestock breeding production competitiveness.

description: Using silicon MOSFETs with thin (5nm) thermally grown SiO2 gate dielectrics, we characterize the density of electrically active traps at low-temperature after 16keV phosphorus ion-implantation through the oxide. We find that, after rapid thermal annealing at 1000oC for 5 seconds, each implanted P ion contributes an additional 0.08 plus/minus 0.03 electrically active traps, whilst no increase in the number of traps is seen for comparable silicon implants. This result shows that the additional traps are ionized P donors, and not damage due to the implantation process. We also find, using the room temperature threshold voltage shift, that the electrical activation of donors at an implant density of 2x10^12 cm^-2 is ~100%.
