description: The problem of optimization of the term of planting greenhouse lettuce is considered. The main aim was maximization of a profit function (economic surplus). Profits from lettuce production and sale in dependence of the term of planting were observed. The problem consists is in estimation of the optimum term of planting lettuce. Lettuce planted in this term should reach the required weight in the moment, in which the profit from its sale will be maximal. / Synopsis. W naukach ekonomiczno-rolniczych często pojawia się problem optymalizacji, czyli wyznaczenia najlepszego rozwiązania z punktu widzenia określonego kryterium (np. wielkości kosztów, wielkości produkcji, wielkości zysku, wydajności itp.). Zadania optymalizacyjne pojawiają się nie tylko w rozważaniach teoretycznych, ale również, a może przede wszystkim, dotyczą praktyków. Przykładem takiego zagadnienia jest omawiany w niniejszej pracy problem maksymalizacji zysku ze sprzedaży sałaty masłowej uprawianej w szklarniach w okresie jesienno-zimowym. W przeprowadzonych badaniach obserwowany był zysk z uprawy i sprzedaży sałaty w zależności od terminu jej wysadzenia. Głównym celem było oszacowanie optymalnego terminu sadzenia sałaty w przypadku, gdy nie są spełnione założenia klasycznej metody najmniejszych kwadratów. Sałata posadzona w tym terminie powinna osiągnąć z góry założoną masę handlową główki w momencie, w którym zysk będzie maksymalny.

description: We present an operator space version of Rieffel's theorem on the agreement of the metric topology, on a subset of the Banach space dual of a normed space, from a seminorm with the weak*-topology. As an application we obtain a necessary and sufficient condition for the matrix metric from an unbounded Fredholm module to give the BW-topology on the matrix state space of the $C^*$-algebra. Motivated by recent results we formulate a non-commutative Lipschitz seminorm on a matrix order unit space and characterize those matrix Lipschitz seminorms whose matrix metric topology coincides with the BW-topology on the matrix state space.

The effects of ethanol on the physical development, nervous system development and behaviour of Caenorhabditis elegans
Creators: name: Davis, Justin Robert
Publisher: name: University of British Columbia
Year: 2010

description: In this thesis I have used the nematode worm Caenorhabditis elegans to study the effects of ethanol exposure on basic physical development and on specific aspects of nervous system development and behaviour. In the first part of this thesis I investigated how chronic exposure to ethanol affects the physical development and life history of worms. I found that chronic exposure to ethanol negatively impacts C. elegans size, rate of development, reproductive fecundity and life expectancy. I further investigated how exposure to ethanol during embryonic development affects this system by exposing eggs to ethanol for 1 hour a different time points during embryogenesis. I found that embryos exposed acutely to ethanol early in their development have a lower probability of hatching into larval worms, and those worms that do hatch display distinct dysmorphologies. In the second part of the thesis I examined how chronic exposure to ethanol affects the C. elegans nervous system and behaviour. In this set of experiments I found the total amount of GFP expression of two different pan-neuronal genes was decreased relative to the size of worms as a result of chronic exposure to ethanol. To determine whether this decrease in apparent size of the nervous system due to ethanol exposure affected the behavior of adult worms I examined two simple, well-studied behaviours: tap withdrawal which is mediated in part by glutamatergic neurotransmission, and the basal slowing response which is mediated by dopaminergic neurotransmission. I found that chronic ethanol exposure attenuated the tap withdrawal response, but did not affect the basal slowing response. To investigate the effects of ethanol on the tap withdrawal circuit I examined the expression patterns of two genes that are expressed in the mechanosensory circuit. I found that the expression of GLR-1::GFP, a non-NMDA type glutamate receptor sub-unit expressed on the interneurons of the tapwithdrawal circuit, is increased as a result of chronic exposure to ethanol. I also found that the timing of the development of the post-embryonic mechanosensory cells is affected by chronic exposure to ethanol. Together these alterations in the tap circuit could have produced the behavioural changes observed. In this thesis I have characterized the effects of ethanol on the basic biology, nervous system and behaviour of C. elegans with the specific aim of generating data to support further investigations of the effects of ethanol on nervous system development and behaviour in this system.

Very low overhead fault-tolerant magic state preparation using redundant ancilla encoding and flag qubits

Publisher: name: arXiv
Year: 2020

description: The overhead cost of performing universal fault-tolerant quantum computation for large scale quantum algorithms is very high. Despite several attempts at alternative schemes, magic state distillation remains one of the most efficient schemes for simulating non-Clifford gates in a fault-tolerant way. However, since magic state distillation circuits are not fault-tolerant, all Clifford operations must be encoded in a large distance code in order to have comparable failure rates with the magic states being distilled. In this work, we introduce a new concept which we call redundant ancilla encoding. The latter combined with flag qubits allows for circuits to both measure stabilizer generators of some code, while also being able to measure global operators to fault-tolerantly prepare magic states, all using nearest neighbor interactions. In particular, we apply such schemes to a planar architecture of the triangular color code family. In addition to our scheme being suitable for experimental implementations, we show that for physical error rates near $10^{-4}$ and under a full circuit-level noise model, our scheme can produce magic states using an order of magnitude fewer qubits and space-time overhead compared to the most competitive magic state distillation schemes. Further, we can take advantage of the fault-tolerance of our circuits to produce magic states with very low logical failure rates using encoded Clifford gates with noise rates comparable to the magic states being injected. Thus, stabilizer operations are not required to be encoded in a very large distance code. Consequently, we believe our scheme to be suitable for implementing fault-tolerant universal quantum computation with hardware currently under development.

It provides guidelines for industry to develop an accurate numerical model of a freight train with any local loading configuration. Additionally, it investigates the influences of loading configuration and cross-wind on the flow structures around, and the aerodynamic forces on, a section of a freight train. Furthermore, it investigates the change in the drag on a loaded wagon with respect to its position along the length of a train through modelling a very long section of a freight train.

description: We report a study exploring how the use of deep neural networks with astronomical Big Data may help us find and uncover new insights into underlying phenomena: through our experiments towards unsupervised knowledge extraction from astronomical Big Data we serendipitously found that deep convolutional autoencoders tend to reject telluric lines in stellar spectra. With further experiments we found that only when the spectra are in the barycentric frame does the network automatically identify the statistical independence between two components, stellar vs telluric, and rejects the latter. We exploit this finding and turn it into a proof-of-concept method for removal of the telluric lines from stellar spectra in a fully unsupervised fashion: we increase the inter-observation entropy of telluric absorption lines by imposing a random, virtual radial velocity to the observed spectrum. This technique results in a non-standard form of ``whitening'' in the atmospheric components of the spectrum, decorrelating them across multiple observations. We process more than 250,000 spectra from the High Accuracy Radial velocity Planetary Search (HARPS) and with qualitative and quantitative evaluations against a database of known telluric lines, show that most of the telluric lines are successfully rejected. Our approach, `Stellar Karaoke', has zero need for prior knowledge about parameters such as observation time, location, or the distribution of atmospheric molecules and processes each spectrum in milliseconds. We also train and test on Sloan Digital Sky Survey (SDSS) and see a significant performance drop due to the low resolution. We discuss directions for developing tools on top of the introduced method in the future.

description: The aim of the paper was to display the agricultural material supply, global production and gross value added in agriculture in the EU countries. In higher developed countries the sectors providing means of production and providing services (sphere I) as well as food and fodder processing industry (sphere III) are of the highest importance, while the significance of internal flows in agriculture is rather smaller. Agriculture mainly plays the role of a material supplying sector. In the poorer EU countries, including Poland, the internal supply flow in agriculture is still of the highest importance. The agri-food sector is in an early step of development. Importance of the first sector, especially services, in the material supply of agribusiness ought to increase. The main condition for changing the situation in Poland is to generate an economic growth and to be able to benefit from the CAP instruments. / Synopsis. Celem opracowania jest przedstawienie zaopatrzenia materiałowego (zużycia pośredniego), produkcji globalnej i wartości dodanej brutto w sektorze rolnym w krajach Unii Europejskiej. W krajach o wysokim poziomie rozwoju gospodarczego w zaopatrzeniu materiałowym rolnictwa duże znaczenie posiada sektor wytwarzający środki produkcji i usługi (sfera I) oraz przetwórstwo rolno- spożywcze (sfera III), natomiast obrót wewnętrzny jest na niskim poziomie. Rolnictwo jest głównie działem surowcowym. Z kolei w krajach biedniejszych, w tym w Polsce, w rolnictwie dominujące znaczenie odgrywa produkcja surowców wewnątrz tego sektora, czyli obrót wewnętrzny. Sektor rolny w tych krajach znajduje się we wczesnym stadium przeobrażeń w kierunku nowoczesności. W zaopatrzeniu materiałowym przede wszystkim musi wzrosnąć rola sfery pierwszej, w tym głównie sektora usługowego. Głównym warunkiem przeprowadzenia zmian w tym zakresie jest przede wszystkim wzrost gospodarczy i objęcie całego sektora rolno-żywnościowego instrumentami WPR UE.
Magnetic field dependence of nucleon parameters from QCD sum rules

description: Finite energy QCD sum rules involving nucleon current correlators are used to determine several QCD and hadronic parameters in the presence of an external, uniform, large magnetic field. The continuum hadronic threshold $s_0$, nucleon mass $m_N$, current-nucleon coupling $λ_N$, transverse velocity $v_\perp$, the spin polarization condensate $\langle\bar qσ_{12} q\rangle$, and the magnetic susceptibility of the quark condensate $χ_q$, are obtained for the case of protons and neutrons. Due to the magnetic field, and charge asymmetry of light quarks up and down, all the obtained quantities evolve differently with the magnetic field, for each nucleon or quark flavor. With this approach it is possible to obtain the evolution of the above parameters up to a magnetic field strength $eB < 1.4$ GeV$^2$.

description: Portfolio Selection is an important real-world financial task and has attracted extensive attention in artificial intelligence communities. This task, however, has two main difficulties: (i) the non-stationary price series and complex asset correlations make the learning of feature representation very hard; (ii) the practicality principle in financial markets requires controlling both transaction and risk costs. Most existing methods adopt handcraft features and/or consider no constraints for the costs, which may make them perform unsatisfactorily and fail to control both costs in practice. In this paper, we propose a cost-sensitive portfolio selection method with deep reinforcement learning. Specifically, a novel two-stream portfolio policy network is devised to extract both price series patterns and asset correlations, while a new cost-sensitive reward function is developed to maximize the accumulated return and constrain both costs via reinforcement learning. We theoretically analyze the near-optimality of the proposed reward, which shows that the growth rate of the policy regarding this reward function can approach the theoretical optimum. We also empirically evaluate the proposed method on real-world datasets. Promising results demonstrate the effectiveness and superiority of the proposed method in terms of profitability, cost-sensitivity and representation abilities.

description: Bayesian model reduction provides an efficient approach for comparing the performance of all nested sub-models of a model, without re-evaluating any of these sub-models. Until now, Bayesian model reduction has been applied mainly in the computational neuroscience community on simple models. In this paper, we formulate and apply Bayesian model reduction to perform principled pruning of Bayesian neural networks, based on variational free energy minimization. Direct application of Bayesian model reduction, however, gives rise to approximation errors. Therefore, a novel iterative pruning algorithm is presented to alleviate the problems arising with naive Bayesian model reduction, as supported experimentally on the publicly available UCI datasets for different inference algorithms. This novel parameter pruning scheme solves the shortcomings of current state-of-the-art pruning methods that are used by the signal processing community. The proposed approach has a clear stopping criterion and minimizes the same objective that is used during training. Next to these benefits, our experiments indicate better model performance in comparison to state-of-the-art pruning schemes.

We solve the sewing constraints and determine the bulk-boundary couplings and the boundary three-point couplings. For the D2 brane our solution gives the first explicit results for the structure constants of the twisted symmetric branes in a WZW model. We also compute the boundary four-point functions, providing examples of open string four-point amplitudes in a curved background. We finally discuss the annulus amplitudes, the relation with branes in $AdS_3$ and in $S^3$ and the analogy between the open string couplings in the $H_4$ model and the couplings for magnetized and intersecting branes.

Tensor Formulation of the General Linear Model with Einstein Notation
Creators: name: Kress, Gavin T.
Publisher: name: arXiv
Year: 2023
Subjects: subject: Methodology (stat.ME)
subject: FOS: Computer and information sciences

description: The general linear model is a universally accepted method to conduct and test multiple linear regression models. Using this model one has the ability to simultaneously regress covariates among different groups of data. Moreover, there are hundreds of applications and statistical tests associated with the general linear model. However, the conventional matrix formulation is relatively inelegant which yields multiple difficulties including slow computation speed due to a large number of computations, increased memory usage due to needlessly large data structures, and organizational inconsistency. This is due to the fundamental incongruence between the degrees of freedom of the information the data structures in the conventional formulation of the general linear model are intended to represent and the rank of the data structures themselves. Here, I briefly suggest an elegant reformulation of the general linear model which involves the use of tensors and multidimensional arrays as opposed to exclusively flat structures in the conventional formulation. To demonstrate the efficacy of this approach I translate a few common applications of the general linear model from the conventional formulation to the tensor formulation.

As these evaluations are tedious and repetitive, we look at gamification as a means to motivate and engage experts in XAI evaluation tasks. We explore the problem space associated with gamified expert XAI evaluation. Based on a literature review of 22 relevant studies and seven interviews with experts in XAI evaluation, we elicit knowledge about affected stakeholders, eight needs, eight goals, and seven requirements. Our results help us understand better the problems associated with expert XAI evaluation and paint a broad application potential for gamification to improve XAI expert evaluations. In doing so, we lay the foundation for the design of successful gamification concepts for expert XAI evaluation.

description: We consider a quantum topological frequency converter, realized by coupling a qubit to two slow harmonic modes. The dynamics of such a system is the quantum analog of topological pumping. Our quantum mechanical description shows that an initial state generically evolves into a superposition of two adiabatic states. The topological nature of the coupling between the qubit and the modes splits these two components apart in energy: for each component, an energy transfer at a quantized rate occurs between the two quantum modes, in opposite directions for the two components, reminiscent of the topological pumping. We denote such a superposition of two quantum adiabatic states distinguishable through measures of the modes' energy an adiabatic cat state. We show that the topological coupling enhances the entanglement between the qubit and the modes, and we unveil the role of the quantum or Fubini-Study metric in the characterization of this entanglement.

description: It is known that general convertibility of bipartite entangled states is not possible to arbitrary error without some classical communication. While some trade-offs between communication cost and conversion error have been proven, these bounds can be very loose. In particular, there are many cases in which tolerable error might be achievable using zero-communication protocols. In this work we address these cases by deriving the optimal fidelity of pure state conversions under local unitaries as well as local operations and shared randomness (LOSR). We also uses these results to explore catalytic conversions between pure states using zero communication.

description: We link the notion causality with the orientation of the 2-complex on which spin foam models are based. We show that all current spin foam models are orientation-independent, pointing out the mathematical structure behind this independence. Using the technology of evolution kernels for quantum fields/particles on Lie groups/homogeneous spaces, we construct a generalised version of spin foam models, introducing an extra proper time variable and prove that different ranges of integration for this variable lead to different classes of spin foam models: the usual ones, interpreted as the quantum gravity analogue of the Hadamard function of QFT or as a covariant definition of the inner product between quantum gravity states; and a new class of causal models, corresponding to the quantum gravity analogue of the Feynman propagator in QFT, non-trivial function of the orientation data, and implying a notion of ''timeless ordering''.

description: In 1996, Franke constructed a purely algebraic category that is equivalent as a triangulated category to the E(n)-local stable homotopy category for n^2+n < 2p-2. The two categories are not Quillen equivalent, and his proof uses systems of triangulated diagram categories rather than model categories. Our main result is that in the case n=1 Franke's functor maps the derived tensor product to the smash product. It can however not be an associative equivalence of monoidal categories. The first part of our paper sets up a monoidal version of Franke's systems of triangulated diagram categories and explores its properties. The second part applies these results to the specific construction of Franke's functor in order to prove the above result.

description: After a short historical review, the forest as a working place creating jobs is discussed. Present trends in the forestry workforce in practically all European countries show a continuing sharp decline in the total number of jobs in the forests. When analyzing forest as a working place at local level it appears that a forest holding of 15 000 hectare contributes to creation of 587 jobs including 90 jobs as direct employment, 471 jobs as indirect employment, and 26 jobs as induced employment. Forest jobs provide subsistence for four times more people than the directly employed. / Synopsis. W opracowaniu dokonano analizy zmian leśnictwa jako miejsca pracy. Obecnie we wszystkich „leśnych” krajach europejskich obserwuje się tendencje spadku zatrudnienia bezpośrednio przy realizacji prac leśnych. Z badań przeprowadzonych w Zakładzie Ekonomiki Leśnictwa SGGW wynika, że gospodarstwo leśne o powierzchni 15 tys. ha kreuje 587 miejsc pracy, w tym tylko 90 w formie zatrudnienia bezpośredniego, zaś pośrednio aż 471 miejsc pracy i 26 miejsc w formie zatrudnienia indukowanego. Jedna osoba pracująca w leśnictwie posiada na utrzymaniu w wspólnym gospodarstwie domowym ponad trzy osoby.

description: Analysis of semi-inclusive DIS hadroproduction suggests broadening of transverse momentum distributions at $x$ below a few $10^{-3}$, which can be modeled in the Collins-Soper-Sterman formalism by a modification of impact-parameter-dependent parton densities. We discuss the consequences of such a modification for the production of electroweak bosons at hadron-hadron colliders. If substantial small-$x$ broadening is observed in forward Z boson production in the Tevatron Run-2, it will strongly affect predicted transverse momentum distributions for W, Z, and Higgs boson production at the Large Hadron Collider.

Whistler : a case study of the effects of amenity migration on the resort municipality of whistler and surrounding environs
Creators: name: Gripton, Stuart Valentich
Publisher: name: University of British Columbia
Year: 2010

description: This thesis examines the nature of amenity migration, its effects and related planning strategies and practices through a case study of the Resort Municipality of Whistler (RMOW) and surrounding environs The goal of this study is to provide a descriptive overview of amenity migration in relation to the RMOW and region, primarily from the perspectives of selected key stakeholders as well as documentation from several RMOW and regional sources For some time, the RMOW has been known as a world class destination resort and a progressive leader in various aspects of planning and sustainability Interviews with sixteen key stakeholders revealed a range of familiarity with the concept of amenity migration and considerable knowledge about economic, social and environmental consequences The concept of amenity migration was not used in RMOW and regional planning strategies and practices, raising some question about its conceptualization A major effect of amenity migration was the lack of affordable housing, with subsequent local and regional effects Significant planning measures perceived as effective included the Whistler Housing Authority, Vision 2020 and a regional growth strategy, currently under development. The study identifies the importance of a regional framework for strategic planning and the need for more research, in particular, to enable mountain communities to track their amenity migrants. Two key issues emerged: whether a "resort community" is viable; and the role of planners in relation to serving the diverse interests of stakeholders in these locales. The thesis concludes with implications regarding the continued use of the concept of amenity migration and the importance of the concept for planners, policy development and planning practice related to the phenomenon.
