description: This paper uses a random sample of 881 farmers drawn from eastern and western Kenya to examine the prevalence and drivers of seed and pollen mediated geneflow in the two major sorghum growing regions. It employs both qualitative and quantitative techniques to assess farmers’ awareness of wild sorghum varieties, the practices they use in maintaining varietal purity and the conditioners of their success in maintaining the purity of cultivated varieties. The study finds that, among others, cultural differences, agro-climate and poverty affect the awareness, practices used in maintaining varietal purity and farmers’ success in doing so. These findings have implication for biosafety and policy in Kenya due to the clamour to introduce genetically modified bio-fortified sorghum varieties in Africa.

description: There remains an important need for the development of image reconstruction methods that can produce diagnostically useful images from undersampled measurements. In magnetic resonance imaging (MRI), for example, such methods can facilitate reductions in data-acquisition times. Deep learning-based methods hold potential for learning object priors or constraints that can serve to mitigate the effects of data-incompleteness on image reconstruction. One line of emerging research involves formulating an optimization-based reconstruction method in the latent space of a generative deep neural network. However, when generative adversarial networks (GANs) are employed, such methods can result in image reconstruction errors if the sought-after solution does not reside within the range of the GAN. To circumvent this problem, in this work, a framework for reconstructing images from incomplete measurements is proposed that is formulated in the latent space of invertible neural network-based generative models. A novel regularization strategy is introduced that takes advantage of the multiscale architecture of certain invertible neural networks, which can result in improved reconstruction performance over classical methods in terms of traditional metrics. The proposed method is investigated for reconstructing images from undersampled MRI data. The method is shown to achieve comparable performance to a state-of-the-art generative model-based reconstruction method while benefiting from a deterministic reconstruction procedure and easier control over regularization parameters.

Year: 2004
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We define the notion of an aligned null direction, a Lorentz-signature analogue of the eigenvector concept that is valid for arbitrary tensor types. The set of aligned null directions is described by a a system of alignment polynomials whose coefficients are derived from the components of the tensor. The algebraic properties of the alignment polynomials can be used to classify the corresponding tensors and to put them into normal form. The alignment classification paradigm is illustrated with a discussion of bivectors and of Weyl-type tensors. Note: an earlier version of this manuscript was published in the proceedings of SPT 2004. The present version has been expanded to include a discussion of complexified alignment. Section 4 also corrects errors contained in the earlier manuscript.

description: Dynamical Mean-Field Theory (DMFT) replaces the many-body dynamical problem with one for a single degree of freedom in a thermal bath whose features are determined self-consistently. By focusing on models with soft disordered $p$-spin interactions, we show how to incorporate the mean-field theory of aging within dynamical mean-field theory. We study cases with only one slow time-scale, corresponding statically to the one-step replica symmetry breaking (1RSB) phase, and cases with an infinite number of slow time-scales, corresponding statically to the full replica symmetry breaking (FRSB) phase. For the former, we show that the effective temperature of the slow degrees of freedom is fixed by requiring critical dynamical behavior on short time-scales, i.e. marginality. For the latter, we find that aging on an infinite number of slow time-scales is governed by a stochastic equation where the clock for dynamical evolution is fixed by the change of effective temperature, hence obtaining a dynamical derivation of the stochastic equation at the basis of the FRSB phase. Our results extend the realm of the mean-field theory of aging to all situations where DMFT holds.

description: The QED contribution to the anomalous magnetic moments of electron and muon are known very precisely up to the order $α^4$. However, the knowledge of $α^5$ term will also be required when the precision of measurement improves further. This paper reports the first systematic attempt to evaluate the $α^5$ term. Feynman diagrams contributing to this term can be classified into six gauge-invariant sets which can be subdivided further into 32 gauge-invariant subsets. Thus far we have numerically evaluated all integrals of 17 gauge-invariant subsets which contain light-by-light-scattering subdiagrams and/or vacuum-polarization subdiagrams. They cover most of leading terms of muon $g-2$ and lead to a preliminary result 663(20) $(α/π)^5$, which is 8.5 times more precise than the old estimate.

description: Nb3Sn is a promising next-generation material for superconducting radiofrequency cavities, with significant potential for both large scale and compact accelerator applications. However, so far, Nb3Sn cavities have been limited to cw accelerating fields <18 MV/m. In this paper, new results are presented with significantly higher fields, as high as 24 MV/m in single cell cavities. Results are also presented from the first ever Nb3Sn-coated 1.3 GHz 9-cell cavity, a full-scale demonstration on the cavity type used in production for the European XFEL and LCLS-II. Results are presented together with heat dissipation curves to emphasize the potential for industrial accelerator applications using cryocooler-based cooling systems. The cavities studied have an atypical shiny visual appearance, and microscopy studies of witness samples reveal significantly reduced surface roughness and smaller film thickness compared to typical Nb3Sn films for superconducting cavities. Possible mechanisms for increased maximum field are discussed as well as implications for physics of RF superconductivity in the low coherence length regime. Outlook for continued development is presented.
Cortical activity following restoration of elevated intraocular pressures to normal pre-laser pressures in a primate model of glaucoma
Creators: name: Jim, Janey
Publisher: name: University of British Columbia
Year: 2009

description: Glaucoma is a group of diseases that affects the optic nerve, causing debilitating visual deficits with no known cures. The primate model of glaucoma was developed to enable investigators to study this disease. Research in glaucoma has examined the disease at the level of the eye and optic nerve head. Recent evidence has also emerged extending glaucomatous injury to the central nervous system. While changes in metabolic activity in response to elevated intraocular pressure (IOP) have been reliably demonstrated, few studies exist that examine metabolic activity following the lowering of elevated levels of IOP to normal values. This study looks at the effects of lowering IOP, following elevated IOP levels of 2 and 4 weeks, by comparing the metabolic activity levels between ocular dominance bands in the primary visual cortex. Elevated IOP (> 30 mmHg) was induced by unilateral lasering of the trabecular " meshwork of primates. The animals' IOP was periodically monitored over a period of 2, 4, 8, and 16 weeks. The first set of animals was sacrificed following the designated period of elevated IOP. A second set of animals had their IOP returned to normal prelaser values (< 20 mmHg) by trabeculectomy following deprivation. They were allowed to survive for several months with normal pre-laser IOP values before being sacrificed. All animals' cortices were histochemically processed for cytochrome oxidase (CO). OD ratios comparing the CO density values of ocular dominance bands were obtained. CO density was found to be lower in deprived eye columns than in non-deprived eye columns as early as 2 weeks post elevated IOP, suggesting that a decrease in metabolic activity in the eye subjected to elevated IOP occurs. Further, OD ratios comparing the metabolic activity between deprived and non-deprived eye bands are affected by the duration of deprivation. Animals subject to longer periods of elevated IOP had ratios further away from values of normal animals. Moreover, animals without pressure lowering therapy had lower OD ratios compared to animals with trabeculectomy performed. Our results suggest that lowering elevated IOP to normal levels has an effect on metabolic activity within the primary visual cortex.

description: Selection of starbursts through either deep narrow band imaging of redshifted Ly-alpha emitters, or localisation of host galaxies of gamma-ray bursts both give access to starburst galaxies that are significantly fainter than what is currently available from selection techniques based on the continuum (such as Lyman-break selection). We here present results from a survey for Ly-alpha emitters at z=3, conducted at the European Southern Observatory's Very Large Telescope. Furthermore, we briefly describe the properties of host galaxies of gamma-ray bursts at z>2. The majority of both Ly-alpha and gamma-ray burst selected starbursts are fainter than the flux limit of the Lyman-break galaxy sample, suggesting that a significant fraction of the integrated star formation at z~3 is located in galaxies at the faint end of the luminosity function.

description: Simultaneous multi-slice (SMS) imaging accelerates MRI data acquisition by exciting multiple image slices simultaneously. Overlapping slices are then separated using a mathematical model. Several parameters used in SMS reconstruction impact the quality of final images. Therefore, finding an optimal set of reconstruction parameters is critical to ensure that SMS acceleration does not significantly degrade resulting image quality. Gradient-echo echo planar imaging (EPI) data were acquired with a range of SMS acceleration factors from volunteers. Images were collected using two head coils (a 48-channel array and a smaller 32-channel array). Data from these coils were reconstructed offline using a range of coil compression factors and reconstruction kernel parameters. A hybrid space (ky-x), externally-calibrated coil-by-coil slice unaliasing approach was used for image reconstruction. The resulting SMS images were compared with identical EPI data acquired without SMS. A functional MRI (fMRI) experiment was also performed and group analysis results were compared between data sets reconstructed with different coil compression levels. The 32-channel coil with smaller dimensions outperformed the larger 48-channel coil in our experiments. Generally, a large calibration region and small kernel sizes in ky direction improved image quality. Use of regularization in the kernel fitting procedure had a notable impact. With optimal selection of other hyperparameters in the hybrid space SMS unaliasing algorithm, coil compression caused small reduction in quality in SMS accelerated images. Similarly, group analysis of fMRI results did not show a significant influence of coil compression on resulting image quality. Hyperparameters used in SMS reconstruction need to be fine-tuned once the experimental factors such as the RF receive coil and SMS factor have been determined.

description: This study examines the impact of facilitated business-to-business (B2B) word-of-mouth (WOM) on participants' information transmission decisions. We also examine characteristics of WOM participants and determine the types of participants who spread information. Understanding WOM participants' information sharing decisions is extremely important to agribusinesses using WOM in their marketing mix. For an expendable crop input, the most important factor in determining whether producers share WOM initiative information with peers is how often they are asked for advice by their peers. In contrast, for an expendable companion animal product the most important factor in determining whether veterinarians share WOM initiative information with peers is whether they had a satisfactory experience in the WOM initiative.
Measuring online consumer perceptions of fair information practices

Year: 2009

description: The expansion of e-commerce has made consumer privacy issues more salient and pressing. Previous studies of online commerce have indicated that limited confidence in privacy protection has been a major problem impeding the growth of e-commerce. The United States Federal Trade Commission developed the Fair Information Practice Principles in its 1998 report to congress to ensure that the collection and use of personal information is conducted fairly, and to provide sufficient privacy protection for consumers. The Federal Trade Commission's core principles are notice, choice, access, and security. The purpose of this study is to develop an instrument to measure the degree to which online entities adhere to fair information practice principles, from the perspective of consumers. The instrument development process included three stages: item creation, card sorting, and instrument testing. First, we generated 25 items based on the definitions of the four fair information principles. Then, we asked eight judges to sort the items into various categories, and according to the card sorting results, we deleted some poor items from the scales. Finally, we conducted an online survey to test the instrument. We applied factor analysis and other validity and reliability analyses to the survey data, resulting a validated 23-item, five-scale instrument. This instrument can be used to evaluate the privacy protection practices of online entities, and to judge from the consumers' perspective if these practices are fair and provide sufficient protection.

Among the results are expressions for the surface pressure for free and periodic boundary conditions and the adjacency pressure, i.e., the difference between the pressure of a box and the sum of the pressures of adjacent sub-boxes in which the box can been decomposed. We show that all those terms indeed behave proportionally to the surface size and prove the existence in the thermodynamic limit of the adjacency pressure.

description: Increasing frequency of epidemiological crisis and their disastrous consequences are motivating nations, around the world, to introduce traceability systems. Traceability systems enable identification, prevention of propagation, and control of diseases and health problems in the shortest possible delay. However, while this effort is praise worthy and indeed necessary, the implementation of a traceability system is complicated primarily because it involves additional constraints and costs to the industry. This article describes the introduction and success of a compulsory traceability system in the Quebec province of Canada by presenting the approach and the strategies that were adopted to minimize constraints and generate opportunities for the industry.

description: The disparity of consumption expenditure among rural areas in China was studied. Then income and living expenditure of rural residents were divided into 5 grades. Principle and method of Cluster Analysis were introduced. Next, Cluster Analysis was adopted to research the disparity of rural consumption expenditure among various areas. Results showed that income and consumption expenditure of 31 districts, cities and provinces could be divided into 5 classes. Shanghai City was the only city rated as the first-class areas with highest income and consumption. 7 cities and provinces were rated as the top three classes of areas. Taking Hebei and Jilin Province as the representatives, most parts of the fourth-class areas were located in northeast part of China with poor cultivated land, which will lead to slow development of rural economy. The fifth-class areas represented by Chongqing City and Sichuan Province were constrained by natural factors with frequent disasters as well as underdevelopment of industry and agriculture, which could not play an improving role in rural development. On this basis, relevant policy countermeasures were put forward.
$ZZγ$ and $Zγγ$ couplings at linear $e^{+} e^{-}$ collider energies with the effects of Z polarization and initial state radiation

description: The constraints on the neutral gauge boson couplings, $ZZγ$ and $Zγγ$, are investigated at linear $e^{+}e^{-}$ collider energies through the $Zγ$ production with longitudinal and transverse polarization states of the final Z boson. Because of high energy of linear electron- positron beams, initial state radiation (ISR) considerably changes the production cross section. We obtain an increase in the cross section by a factor of 2-3 due to ISR for transverse polarization and by a factor of 10-100 for longitudinal polarization states depending on the energy. We find the 95% C.L. limits on the CP conserving form factors $h_{3}^{Z}$, $h_{4}^{Z}$, $h_{3}^γ$ and $h_{4}^γ$ with integrated luminosity 500$fb^{-1}$ and $\sqrt{s}=$0.5, 1, 1.5 TeV energies. It is shown that the longitudinal polarization of the Z boson, together with ISR, can improve sensitivities by factors 2-3.

description: The necessity of taking government as the implementing subject in the construction of new countryside was analyzed from the aspects such as narrowing urban-rural gap, government’s responsibility, connotation and complexity of new countryside construction. Dynamic mechanism of government in the construction of new countryside was discussed, and some problems were introduced. The basic reason of these problems was the deficiency of government’s publicity. Firstly, self-interest of government led to the deviation of public target. Secondly, government was controlled by superior groups, thus benefits of vulnerable groups can’t be ensured. On this basis, establishing an incentive and constraint mechanism for government officers was put forward. It was essential to make full play of government’s self-interest, establish a scientific system and mechanism for assessing political achievements, regulate government’s behaviors and implement extensive socialization supervision of public rights.

Results obtained from a frozen-phonon approach as well as from molecular dynamics simulations are compared. We further suggest that the effect of structural fluctuations can be qualitatively captured by the Anderson model with bond disorder. The influence of individual vibrational modes on the electronic transport is discussed as well as the role of zero-point fluctuations.

description: Official statistics are used to expatiate the general state of female labor force employment and transfer in rural China. According to the “structure” problem of female labor force transfer, it is pointed out that the overall cultural quality of rural women is relatively low, a large number of rural middle-aged women stay at home, social security system is lacked and the social service system is not perfect, which are the major factors restricting the transfer of rural female labor force. Therefore, according to the problems in employment and transfer of female labor force in rural China, countermeasures are put forward, which are ① improving cultural quality, skill and competitiveness of rural female labor force, ② perfecting labor market and social security system, ③ developing labor-intensive rural enterprises and implementing agricultural industrialization management. All these are of great significance to promote the orderly transfer of labor force, as well as the process of urbanization in China.

description: Recent works on observation of discrete time-crystalline signatures throw up major puzzles on the necessity of localization for stabilizing such out-of-equilibrium phases. Motivated by these studies, we delve into a clean interacting Floquet system, whose quasi-spectrum conforms to the ergodic Wigner-Dyson distribution, yet with an unexpectedly robust, long-lived time-crystalline dynamics in the absence of disorder or fine-tuning. We relate such behavior to a measure zero set of nonthermal Floquet eigenstates with long-range spatial correlations, which coexist with otherwise thermal states at near-infinite temperature and develop a high overlap with a family of translationally invariant, symmetry-broken initial conditions. This resembles the notion of "dynamical scars" that remain robustly localized throughout a thermalizing Floquet spectrum with fractured structure. We dub such a long-lived discrete time crystal formed in partially nonergodic systems, "scarred discrete time crystal" which is distinct by nature from those stabilized by either many-body localization or prethermalization mechanism.

Fidelity-susceptibility analysis of the honeycomb-lattice Ising antiferromagnet under the imaginary magnetic field

description: The honeycomb-lattice Ising antiferromagnet subjected to the imaginary magnetic field $H=iθT /2$ with the "topological" angle $θ$ and temperature $T$ was investigated numerically. In order to treat such a complex-valued statistical weight, we employed the transfer-matrix method. As a probe to detect the order-disorder phase transition, we resort to an extended version of the fidelity $F$, which makes sense even for such a non-hermitian transfer matrix. As a preliminary survey, for an intermediate value of $θ$, we investigated the phase transition via the fidelity susceptibility $χ_F^{(θ)}$. The fidelity susceptibility $χ_F^{(θ)}$ exhibits a notable signature for the criticality as compared to the ordinary quantifiers such as the magnetic susceptibility. Thereby, we analyze the end-point singularity of the order-disorder phase boundary at $θ=π$. We cast the $χ_F^{(θ)}$ data into the crossover-scaling formula with $δθ= π-θ$ scaled carefully. Our result for the crossover exponent $ϕ$ seems to differ from the mean-field and square-lattice values, suggesting that the lattice structure renders subtle influences as to the multi-criticality at $θ=π$.
Centre Shift of the Raman Scattered He II $λ$ 4850 in the Symbiotic Star V1016 Cygni

description: We present our spectroscopic data around H$β$ of the symbiotic star V1016 Cyg obtained with the Bohyunsan Echelle Spectrograph, in order to secure the broad emission feature at around 4850Å, which is formed through Raman scattering of He II $λ$ 972. The total cross section around Ly$γ$ is approximately given by $σ(λ)\simeq 1.7\times 10^{-28}[λ_{Lyγ}/(λ-λ_{Lyγ})]^2{\rm cm^2}$, with $λ_{Lyγ}$ being the line centre wavelength of Ly$γ$. We find a centre shift redward by an amount $Δλ= +0.64{\rm Å}$ in the Raman scattered He II $λ$ 4850. This redward centre shift is exactly analogous to the effect for the Raman scattered He II $λ$ 6545 blueward of H$α$ discussed in our previous study. We compute the branching ratios of Raman scattering into the level $2s$ and levels $3s,$ and 3d, which are subsequently incorporated in our Monte Carlo code. Assuming that He II $λ$ 972 emission is characterized by a single Gaussian profile, the redward peak shift observed in the Raman scattered He II 4850 feature corresponds to the neutral column density $N_{HI}=1.2\times 10^{21}{\rm\ cm^{-2}}$. Assuming that the covering factor $\sim 0.1$ of the scattering region with respect to the He II emission region and adopting a simple spherical stellar wind model, we may place an upper bound $\dot M \le 3.6\times 10^{-7}{\rm M_\odot yr^{-1}}$ for the mass loss rate of the giant component of V1016 Cyg. Our estimate can be severely affected by the inematics of the scattering and He II emission regions and the exact atomic physics, about which brief discussions are presented.

description: A. Aim

The aim of this course was to show how the quality and usefulness of food composition data is determined by the quality of the processes involved in the production of nutrient data in foods, and the compilation of these and other data into food composition tables and nutritional database. The course is based on the philosophy that the preparation of nutritional databases requires close understanding of the needs of the users by both compilers and producers of analytical data, internationally and within the EuroFIR consortium. The course aimed to show how this understanding can be achieved and demonstrate the benefits of collaboration between users, analysts and compilers.

description: We summarize the status of rural areas in China, and introduce the principle of Cluster Analysis. According to related statistical data, per capita net income of rural households in various regions of China is analyzed by adopting the method of Cluster Analysis. The results showed that 31 cities, autonomous regions and provinces in China can be divided into 4 types. The first type includes Beijing and Shanghai. Comprehensive economic strengths of these regions, as well as per capita net income of rural households, are in the forefront. The second type includes Tianjin, Jiangsu and Zhejiang Provinces of China, which have superior conditions of agricultural production with excellent foundation of agriculture and stable income sources. The third type includes Liaoning, Shandong, Fujian and Guangdong. The 4 provinces are located in eastern coastal area which have abundant marine resources and relatively higher living level of rural residents, and are suitable for the growth of crops. The rest regions can be classified into the fourth type, which have lower agricultural output and per capita net income of rural households due to the impacts of location and climate condition.

description: We present results of an initial search for clusters of galaxies at z~1 and above, using data from 2.9 square degrees of XMM-Newton images. By selecting weak potentially extended X-ray sources with faint or no identifications in deep, ground-based optical imaging, we have constructed a starting sample of 19 high redshift cluster candidates. Near-IR and R,z' imaging of these fields identified nine of them as high redshift systems. Six of these were confirmed spectroscopically, three at z~1.0 and the other three in 0.8~1 clusters, after discarding "low" redshift systems at z ~2.5 10^{-15} ergs/cm2/s ([0.5-2] keV) and this is a lower limit, having screened not all potential z~1 candidate clusters. Coordinates, x-ray measures and evidence for nine x-ray selected high redshift clusters is given.

description: China’s exports of apples and pears to the EU are increasing, although EU imports are restricted by the EU entry price system (EPS). The EPS aims to prevent imports below the entry price, which acts as a minimum import price, to protect EU growers of apples and pears. This study investigates the restrictiveness of the EPS for Chinese exports of apples and pears to the EU. Results suggest that the high effectiveness of the EPS for apples originating in China limits to the years 2003, 2004 and 2005. For pears originating in China, our results indicate that the EPS is relevant throughout the whole period underlying this analysis, with the highest relevance prevailing in 2004, 2005 and 2006. In the future, the relevance of the EPS is expected to decline.
Exploring color-octet scalar parameter space in minimal $R$-symmetric models

description: In this work we study the collider phenomenology of color-octet scalars (sgluons) in minimal supersymmetric models endowed with a global continuous $R$ symmetry. We systematically catalog the significant decay channels of scalar and pseudoscalar sgluons and identify novel features that are natural in these models. These include decays in nonstandard diboson channels, such as to a gluon and a photon; three-body decays with considerable branching fractions; and long-lived particles with displaced vertex signatures. We also discuss the single and pair production of these particles and show that they can evade existing constraints from the Large Hadron Collider, to varying extents, in large regions of reasonable parameter space. We find, for instance, that a 725 GeV scalar and a 350 GeV or lighter pseudoscalar can still be accommodated in realistic scenarios.

description: We introduce an efficient method to solve the Mott-Hubbard model. The Schrödinger equation is solved by the successive construction of doorway states. The ground state wavefunction derived by this method contains all relevant many-body correlations introduced by the hamiltonian, but the dimensionality of the Hilbert space is greatly reduced. We apply the doorway method to obtain the chemical potential, the on-site fluctuations and the visibility of the interference pattern arising from atoms in a one-dimensional periodic lattice. Excellent agreement with exact numerical calculations as well as recent experimental observations is found.

description: In the next generation of computing, Mobile ad-hoc network (MANET) will play a very important role in the Internet of Things (IoT). The MANET is a kind of wireless networks that are self-organizing and auto connected in a decentralized system. Every device in MANET can be moved freely from one location to another in any direction. They can create a network with their neighbors’ smart devices and forward data to another device. The IoTCloud-MANET framework of smart devices is composed of IoT, cloud computing, and MANET. This framework can access and deliver cloud services to the MANET users through their smart devices in the IoT framework where all computations, data handling, and resource management are performed. The smart devices can move from one location to another within the range of the MANET network. Various MANETs can connect to the same cloud, they can use cloud service in a real time. For connecting the smart device of MANET to cloud needs integration with mobile apps. My main contribution in this research links a new methodology for providing secure communication on the internet of smart devices using MANET Concept in 5G. The research methodology uses the correct and efficient simulation of the desired study and can be implemented in a framework of the Internet of Things in 5G.

description: Mesenchymal stem cells and multipotent adult progenitor cells (MAPCs) have been proposed as novel therapeutics for solid organ transplant recipients with the aim of reducing exposure to pharmacological immunosuppression and its side effects. In the present study, we describe the clinical course of the first patient of the phase I, dose-escalation safety and feasibility study, MiSOT-I (Mesenchymal Stem Cells in Solid Organ Transplantation Phase I). After receiving a living-related liver graft, the patient was given one intraportal injection and one intravenous infusion of third-party MAPC in a low-dose pharmacological immunosuppressive background. Cell administration was found to be technically feasible; importantly, we found no evidence of acute toxicity associated with MAPC infusions.

description: We study steady bifurcation for the coupled system body-liquid consisting of a sphere freely falling in a Navier-Stokes liquid under the action of gravity. In particular we show that, under the assumption that for the bifurcating solution the translational velocity of the sphere is parallel to the gravity, bifurcation takes place provided 1 is a simple eigenvalue of a suitable linear operator and the transversality property holds.

description: Food markets are becoming global and competition in all markets is intense, countries are working to improve market access through the current round of World Trade Organization negotiations and through regional agreements such as the Free Trade Area of the Americas. Trade is critical to Canada's agri-food sector. Canada is a major agricultural producer with a relatively small population. As a result, we export almost half of our farm products. Because of the magnitude of our exports, the success of the agri-food sector depends, in large part, on international markets.

description: The geometric quantization problem is considered from the point of view of the Davies and Lewis approach to quantum mechanics. The influence of the measuring device is accounted in the classical and quantum case and it is shown that the conditions of the measurement define the type of quantization (Weyl, normal, antinormal, etc.). The quantum states and quantum operators are obtained by means of the projection, defined from the system of generalized coherent states.
