description: The photonic hook (PH) is new type of curved light beam which has promising applications in various fields such as nanoparticle manipulation, super-resolution imaging, etc. Herein, we proposed a new approach of utilizing patchy microcylinders for the generation of PHs. Numerical simulation based on the finite-difference time-domain method was used to investigate the field distribution characteristics of the PHs. By rotating the patchy microcylinder, PHs with different curvatures can be effectively generated, and the PH with a bending angle of 28.4$^\circ$ and a full-width-half-maximum of 0.36 $λ$ can be obtained from 1 $μ$m-diameter patchy microcylinders.

Farmers Decision Making Behavior/Empirical Findings from Denmark

description: Farmers decisions are often based on past experience which is then transformed into simple "rules of thumb". These rules are quick, easy and cheap, but seem to have some deficiencies compared to the assumptions in neo-classical economic theory. This is one of the preliminary findings from interviews among 25 Danish full time farmers. In general, the short-run decision rules are aimed at maximizing profit, whereas decision rules concerning intermediate and long-run decisions seemed to have a tendency of underestimating capital and labour costs, but overvaluing tax-reductions. The rules seemed in most cases to be based on marginal cost principles, where average cost principles may have been more appropriate. The long- run decisions, although affected by non-economic goals, are probably not irrational, but the farmers are perhaps not aware of the risk they take in order to meet these goals.

description: On modern architectures, the performance of 32-bit operations is often at least twice as fast as the performance of 64-bit operations. By using a combination of 32-bit and 64-bit floating point arithmetic, the performance of many dense and sparse linear algebra algorithms can be significantly enhanced while maintaining the 64-bit accuracy of the resulting solution. The approach presented here can apply not only to conventional processors but also to other technologies such as Field Programmable Gate Arrays (FPGA), Graphical Processing Units (GPU), and the STI Cell BE processor. Results on modern processor architectures and the STI Cell BE are presented.

description: The main goal of this project was to develop improved financial management tools for the individual farmer and to establish a basis for better advisory services. The assessment phase examines the present situation: What are the farmer's financial management requirements, and how do the available tools meet these needs? Interviews with selected farmers revealed that many of them have been keeping their finances in good order through the use of simple tools such as bank statements, tax accounting and experience. Opportunities to discuss financial questions and receive comments on or analysis of their accounts were areas in which many felt their needs were not met. Farm management tools should provide an overview, create a foundation based on standard principles, provide explanatory comments and stimulate the farmer's involvement. In the project's development phase, management tools were developed on the basis of these guidelines. These new tools will be tested in the time ahead.

description: Recently, a boxology (graphical language) with design patterns for hybrid AI was proposed, combining symbolic and sub-symbolic learning and reasoning. In this paper, we extend this boxology with actors and their interactions. The main contributions of this paper are: 1) an extension of the taxonomy to describe distributed hybrid AI systems with actors and interactions; and 2) showing examples using a few design patterns relevant in multi-agent systems and human-agent interaction.

description: We develop techniques to compute multi-instanton corrections to the 1/N expansion in matrix models described by orthogonal polynomials. These techniques are based on finding trans-series solutions, i.e. formal solutions with exponentially small corrections, to the recursion relations characterizing the free energy. We illustrate this method in the Hermitian, quartic matrix model, and we provide a detailed description of the instanton corrections in the Gross-Witten-Wadia (GWW) unitary matrix model. Moreover, we use Borel resummation techniques and results from the theory of resurgent functions to relate the formal multi-instanton series to the nonperturbative definition of the matrix model. We study this relation in the case of the GWW model and its double-scaling limit, providing in this way a nice illustration of various mechanisms connecting the resummation of perturbative series to nonperturbative results, like the cancellation of nonperturbative ambiguities. Finally, we argue that trans-series solutions are also relevant in the context of topological string theory. In particular, we point out that in topological string models with both a matrix model and a large N gauge theory description, the nonperturbative, holographic definition involves a sum over the multi-instanton sectors of the matrix model

Efficiency and Size of Agricultural Production Capacity: A Cost Analysis of Danish Farms
Creators: name: Lund, Mogens
name: Pedersen, Dorthe E.

Publisher: name: Unknown
Year: 1993
Subjects: Productivity Analysis

description: The aim of this paper is to measure the cost and size efficiency with respect to allocated production capacity in danish agriculture. In this study 98 cash crop farms, 248 dairy farms and 185 pig farms have been investigated.
A linear programming approach has been adopted in order to calculate the different efficiency scores. One main conclusion is that there exists great opportunities for a better cost allocation of the production capacity in Danish agriculture. However, another main conclusion is that differences in the size of farm capacity is not the most significant explanation for inefficiencies in the capacity costs of the farms investigated.

description: The objective of this paper is to analyse the economics of an erosion control project in the Ipero Stream Watershed, in Brazil. Soil loss for each hectare is estimated by the Universal Loss Equation, taking into account its natural erosion potential and cultivated crop. These values are then compared with the limits of soil loss tolerance and the results used for conservation policies' recommendations. Net Present Values (NPVs) for the difference between "with project" and "without project" situations are estimated for a period of 15 years. For the whole watershed, the NPVs are positive, partially due to low cost management practices which would be sufficient to control soil erosion for approximately 68% of the studied area.

Another forbidden solar oxygen abundance: the [O I] 5577 A line

Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Context: Recent works with improved model atmospheres, line formation, atomic and molecular data, and detailed treatment of blends, have resulted in a significant downward revision of the solar oxygen abundance. Aims: Considering the importance of the Sun as an astrophysical standard and the current conflict of standard solar models using the new solar abundances with helioseismological observations we have performed a new study of the solar oxygen abundance based on the forbidden [OI] line at 5577.34 A, not previously considered. Methods: High-resolution (R > 500 000), high signal-to-noise (S/N > 1000) solar spectra of the [O I] 5577.34 A line have been analyzed employing both three-dimensional (3D) and a variety of 1D (spatially and temporally averaged 3D, Holweger & Muller, MARCS and Kurucz models with and without convective overshooting) model atmospheres. Results: The oxygen abundance obtained from the [OI] 5577.3 A forbidden line is almost insensitive to the input model atmosphere and has a mean value of A(O) = 8.71 +/- 0.02 (σfrom using the different model atmospheres). The total error (0.07 dex) is dominated by uncertainties in the log gf value (0.03 dex), apparent line variation (0.04 dex) and uncertainties in the continuum and line positions (0.05 dex). Conclusions: The here derived oxygen abundance is close to the 3D-based estimates from the two other [OI] lines at 6300 and 6363 A, the permitted OI lines and vibrational and rotational OH transitions in the infrared. Our study thus supports a low solar oxygen abundance (A(O) ~ 8.7), independent of the adopted model atmosphere.

description: Laser Doppler holography (LDH) is a full-field blood flow imaging technique able to reveal human retinal and choroidal blood flow with high temporal resolution. We here report on using LDH in the anterior segment of the eye without making changes to the instrument. Blood flow in the bulbar conjunctiva and episclera as well as in corneal neovascularization can be effectively imaged. We additionally demonstrate simultaneous holographic imaging of the anterior and posterior segments by simply adapting the numerical propagation distance to the plane of interest. We used this feature to track the movements of the retina and pupil with high temporal resolution. Finally, we show that the light backscattered by the retina can be used for retro-illumination of the anterior segment. Hence digital holography can reveal opacities caused by absorption or diffusion in the cornea and eye lens.

description: In farm economics it is realized that farmers vary considerably in capacity and willingness to reach the economic optimal organization of production. This behavioral aspect influences farm structure by the production technology chosen from current options (static situation) and also by differences in the time taken to the adoption of innovations (dynamic situation). In sociology, the resulting levels of productivity under similar natural, social-economic and technical conditions are referred to as "styles of farming". The present paper focuses on the assessment of different styles of farming among arable farmers in a specific region in the Netherlands. Viability perspectives are outlined for these styles considering two scenarios of technical and institutional changes.

description: It has been widely realized that Monte Carlo methods (approximation via a sample ensemble) may fail in large scale systems. This work offers some theoretical insight into this phenomenon in the context of the particle filter. We demonstrate that the maximum of the weights associated with the sample ensemble converges to one as both the sample size and the system dimension tends to infinity. Specifically, under fairly weak assumptions, if the ensemble size grows sub-exponentially in the cube root of the system dimension, the convergence holds for a single update step in state-space models with independent and identically distributed kernels. Further, in an important special case, more refined arguments show (and our simulations suggest) that the convergence to unity occurs unless the ensemble grows super-exponentially in the system dimension. The weight singularity is also established in models with more general multivariate likelihoods, e.g. Gaussian and Cauchy. Although presented in the context of atmospheric data assimilation for numerical weather prediction, our results are generally valid for high-dimensional particle filters.

description: We study the dynamics and resulting score distribution of three-agent games where after each competition a single agent wins and scores a point. A single competition is described by a triplet of numbers $p$, $t$ and $q$ denoting the probabilities that the team with the highest, middle or lowest accumulated score wins. We study the full family of solutions in the regime, where the number of agents and competitions is large, which can be regarded as a hydrodynamic limit. Depending on the parameter values $(p,q,t)$, we find six qualitatively different asymptotic score distributions and we also provide a qualitative understanding of these results. We checked our analytical results against numerical simulations of the microscopic model and find these to be in excellent agreement. The three agent game can be regarded as a social model where a player can be favored or disfavored for advancement, based on his/her accumulated score. It is also possible to decide the outcome of a three agent game through a mini tournament of two-a gent competitions among the participating players and it turns out that the resulting possible score distributions are a subset of those obtained for the general three agent-games. We discuss how one can add a steady and democratic decline rate to the model and present a simple geometric construction that allows one to write down the corresponding score evolution equations for $n$-agent games.
A Canadian Sikh wedding as a cultural performance
Creators: name: Gill, Kuldip
Publisher: name: University of British Columbia
Year: 2010

description: This thesis presents the first extended description of a Canadian Punjabi Sikh Wedding. The cultural events prior to, during and after a wedding, in one rural family in British Columbia, are presented as scenes in a cultural performance. In doing this, an attempt has been made to use ideas from the approaches of Clifford Geertz and Milton Singer. Geertz's notion of 'thick description1 has directed my ethnographic data collection. Singer's idea of cultural performance has given these data a textual form as well as shown me the importance of noting the sequential occurrence of events or concrete social units during the performance of a Sikh wedding. I have explored and commented on Barbara Ward's concept of 'conscious models' in relation to the study of the Sikhs as an immigrant group in Canada. The significance of this ethnography is its description of one avowedly traditional Sikh wedding which included many rites or event sequences. This attempt at 'thick description' may enable others studying other Sikh weddings to note comparatively the impact of events and processes external to this ethnic group on the institution of Sikh marriage. As well, the internal tensions and pressures for change may be revealed by the way marriages are performed in the future. This thesis, thus, provides a base-line for the comparative study of other Sikh weddings. While the primary contribution of this thesis is to the body of ethnographic literature, it should also be useful to people and institutions interested in Ethnicity, Social Change, Women's Studies and those interested in immigrant groups. As the study of one Canadian Sikh wedding in one family, this thesis does not present any general conclusions or generalizations applicable to the whole of Canadian Punjabi Sikh culture.

Sustainable Land Use and Incentive Compatibility

Publisher: name: Unknown
Year: 1993
Subjects: Environmental Economics and Policy

description: The first purpose of this paper is to present a theoretical framework from a sustainable point of view for the economic analysis of cropping behavior. The second is to evaluate economic conditions for the cropping behavior of a radish producing area in Hokkaido,the northern island of Japan,which is among the most rapidly vegetable-growing areas in Japan. To approach these themes,two concepts are incorporated,externality and incentive compatibility,terms often used in public economics,though still hardly used in this field. The author believes these concepts to be effective devices that can be applied in dealing with sustainable issues. Then the role of a producers' agreement for cropping behavior is examined to satisfy the second purpose.

description: We present a fast and efficient tight-binding (TB) method for simulating scanning tunneling microscopy (STM) imaging of adsorbate molecules on ultrathin insulating films. Due to the electronic decoupling of the molecule from the metal surface caused by the presence of the insulating overlayer, the STM images of the frontier molecular orbitals can be simulated using a very efficient scheme, which also enables the analysis of phase shifts in the STM current. Au-pentacene complex adsorbed on a NaCl bilayer on Cu substrate provides an intricate model system, which has been previously studied both experimentally and theoretically. Our calculations indicate that the complicated shape of the molecular orbitals may cause multivalued constant current surfaces -- leading to ambiguity of the STM image. The results obtained using the TB method are found to be consistent with both DFT calculations and experimental data.

description: One hidden yet important issue for developing neural network potentials (NNPs) is the choice of training algorithm. Here we compare the performance of two popular training algorithms, the adaptive moment estimation algorithm (Adam) and the Extended Kalman Filter algorithm (EKF), using the Behler-Parrinello neural network (BPNN) and two publicly accessible datasets of liquid water [Proc. Natl. Acad. Sci. U.S.A. 2016, 113, 8368-8373 and Proc. Natl. Acad. Sci. U.S.A. 2019, 116, 1110-1115]. This is achieved by implementing EKF in TensorFlow. It is found that NNPs trained with EKF are more transferable and less sensitive to the value of the learning rate, as compared to Adam. In both cases, error metrics of the validation set do not always serve as a good indicator for the actual performance of NNPs. Instead, we show that their performance correlates well with a Fisher information based similarity measure.

description: LandSense has implemented various tools, applications and services to promote the implementation of citizen science/crowdsourcing campaigns, assessing the quality of citizen observations and other associated tasks in the domain of land use and land cover monitoring. Some of the tools were provided by consortium partners, and will be continued afterwards independently of LandSense, some will be sustained by other European (or other) projects, and a few have been open sourced for broad accessibility. The deliverable summarizes these tools and applications and provides users with guidelines and training material on how to use them. All of the tools are accessible through LandSense Engagement Platform (LEP, https://landsense.eu), mostly through “Campaigns” and “Innovate” sections. A large part of the deliverable is dedicated to the LandSense Authorization service, which glues the federation of these tools and services together and provides a General Data Protection Regulation (GDPR) compliant framework for citizen science data collection. The online demonstration application, available on the LEP, gives contributors a clear insight into what (personal) data is shared with an application (and between them) based on different scopes. The pillar services change detection and quality assurance (QA) and control services, are presented together with instructions on how to use them or install and run your own (in case of QA service). Finally, a quick overview of the (LandSense) applications and partners’ tools that will continue after the end of the project is indicated to make this deliverable a compendium of LandSense applications, tools and services.
A Diagnosis of the Strengths and Weaknesses in the Staff Management System of a Farm Business with the Aid of the Staff Management Audit Technique: A Case Study in a Developing Country
Creators: name: Oosthuizen, Lukas K.
Publisher: name: Unknown
Year: 1993
Subjects: Farm Management

description: The major aim of the research reported in this paper, was to diagnose and to measure the strengths and weaknesses in the staff management system in a farm business, by recording both the employees’ and the employer’s perceptions, given the fact that most employees had a low level of literacy and therefore could not complete the questionnaires themselves. The case study method was used to gather staff management audit data from the employer and 38 farm workers. Strengths and weaknesses in the staff management system were diagnosed, as well as efficient and effective staff management practices on the one hand and inefficient practices on the other hand. On the basis of the results a strategy could be developed with a view to improving productivity and work satisfaction.

description: Polypterus is an extant fish that is used as a model to understand the fin-to-limb evolutionary transition. Polypterus exhibits muscle phenotypes relevant to this transition. In particular, plastic changes in bone and muscle in Polypterus have been shown in response to spending time in a terrestrial environment. Muscle fiber changes are usually associated with changes in the performance demand placed on those muscles. We hypothesize that muscle fibers are recruited differently between aquatic and terrestrial environments to explain the change in fiber type. How pectoral fin muscle activity changes between swimming and walking is mostly unknown. Hence, this study utilizes electromyography (EMG) and high-speed videography to understand how the muscle activity pattern and function of all four pectoral fin muscle groups change during swimming and walking in aquatically raised fish. In this experiment, aquatically raised fish were placed in water and on land to observe changes in fin muscle function between behaviours. This study aims to understand how the instantaneous changes in the behaviour of the fish, particularly in the pectoral fin, could explain the muscle plasticity found in previous research. This study showed that fish adduct their pectoral fins much faster with increased muscle effort during walking compared to swimming. The adductor muscle also had the biggest change in function, activating for the majority of the fin-stroke cycle and therefore undergoing eccentric contraction. The increase in muscle effort seen in this study is consistent with the muscle fiber transition seen in fish that spend long periods on land, and the dramatic change of EMG magnitudes found in the adductor muscle may explain muscle damage previously found following acute walking.
Diagrammar of physical and fake particles and spectral optical theorem

description: We prove spectral optical identities in quantum field theories of physical particles (defined by the Feynman $iε$ prescription) and purely virtual particles (defined by the fakeon prescription). The identities are derived by means of purely algebraic operations and hold for every (multi)threshold separately and for arbitrary frequencies. Their major significance is that they offer a deeper understanding on the problem of unitarity in quantum field theory. In particular, they apply to "skeleton" diagrams, before integrating on the space components of the loop momenta and the phase spaces. In turn, the skeleton diagrams obey a spectral optical theorem, which gives the usual optical theorem for amplitudes, once the integrals on the space components of the loop momenta and the phase spaces are restored. The fakeon prescription/projection is implemented by dropping the thresholds that involve fakeon frequencies. We give examples at one loop (bubble, triangle, box, pentagon and hexagon), two loops (triangle with "diagonal", box with diagonal) and arbitrarily many loops. We also derive formulas for the loop integrals with fakeons and relate them to the known formulas for the loop integrals with physical particles.

description: Management of large areas of sugar cane plantations require decisions on which areas should be ploughed out, which sugar cane variety should be planted in the ploughed areas, and which field should be harvested first. To answer these questions in an optimal way a linear programming (LP) model has been developed and a software written to generate the LP matrix. Model results for an hypothetical case are in good agreement with generally accepted management practice.

Holstein Friesian Breeding in Holland
Creators: name: Roest, Jan
Publisher: name: Unknown
Year: 1993
Subjects: Livestock Production/Industries

description: Holland is internationally oriented and favours an open dairy cattle breeding policy. We try to obtain the genes from all over the world, whichever suit us best, whether imported or coming from our own dairy population. All these genes are compared under the same uniform Dutch conditions. We are now experiencing a substantial international interest in semen of our best proven sires and offspring (pregnant heifers) of our best dairy cows. For the coming years we aim at giving dairy cattle breeders worldwide an opportunity to improve their herds with selected genes from Holland. The slogan 'Dutch Proven' stands for efficient protein production and functional conformation, and above all reliability of breeding values.

description: Working in a semi-abelian context, we use Janelidze's theory of generalised satellites to study universal properties of the Everaert long exact homology sequence. This results in a new definition of homology which does not depend on the existence of projective objects. We explore the relations with other notions of homology, and thus prove a version of the higher Hopf formulae. We also work out some examples.

Proteolytic activity in plant tissue and cell suspension culture
Creators: name: Nilsson, E. Kristina
Publisher: name: University of British Columbia
Year: 2010

description: Proteolytic enzymes are common in plants but are usually specifi to endogenous protein. Plant proteases with specificities applicable to the food industry include papain, ficin and bromelain. Other plants have been used in traditional methods of food preparation for their proteolytic action on food components. The following species were investigated for propagation in tissue culture: Carica papaya, Ficus carica, Cynara cardunculus, Galium verum, Circium arvense, Dieffenbachia amoena, D. picta and Ananas comosus. Tissues of the first five of these demonstrated proteolytic activity by clearing of milk turbidity in agar medium. Commercial papain and ficin preparations are currently obtained from latex of immature papaya and fig fruit, respectively. This investigation was conducted, in part, to determine the feasibility of producing these two enzymes by the in vitro cell culture technique. Standard method of aseptic seed germination and leaf tissue excision were employed for callus initiation. Cell suspension cultures derived from callus were maintained in B5 medium at 28 °C in darkness. Proteolytic activity was determined by a modification of the Food Chemicals Codex method for papain and protein content was determined by Bradford's dye-binding, method. Production of protein and protease varied among cell cultures, but could be influenced by changes to some nutritional factors. Fig cells were grown in medium supplemented with single amino acids in the presence of either nitrate or ammonia as a source of inorganic nitrogen. All nitrate-based media produced higher yields of cell dry weight than ammonia-based media. Glutamic and aspartic acids were most stimulatory growth, protein accumulation and protease activity of fig cells. Skimmed milk, added at 3% (v/v), was a highly effective growth stimulant, and also resulted in higher protein and protease levels than the amino acids. Fresh casein and whey, added individually, produced similar results to skimmed milk. Citric acid, added at the level found in the 3% milk supplement, also caused stimulation of fig cell growth, protein synthesis and protease activity not significantly different from skimmed milk. It appears that nitrogen accumulation and reduction in fig cells may have been limited by an energy requirement which could be satisfied with the addition of citric acid or milk whey to the basal medium.

Non-linear sigma models on constant curvature target manifolds: a functional renormalization group approach
Creators: name: Efremov, Alexander N.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We study non-linear sigma models on target manifolds with constant (positive or negative) curvature using the functional renormalization group and the background field method. We pay particular attention to the splitting Ward identities associated to the invariance under reparametrization of the background field. Implementing these Ward identities imposes to use the curvature as a formal expansion parameter, which allows us to close the flow equation of the (scale-dependent) effective action consistently to first order in the curvature. We shed new light on previous work using the background field method.
