description: We simulate a densely jammed, athermal assembly of repulsive soft particles immersed in a solvent. Starting from an initial condition corresponding to a quench from a high temperature, we find non-trivial slow dynamics driven by a gradual release of stored elastic energy, with the root mean squared particle speed decaying as a power law in time with a fractional exponent. This decay is accompanied by the presence within the assembly of spatially localised and temporally intermittent `hot-spots' of non-affine deformation, connected by long-ranged swirls in the velocity field, reminiscent of the local plastic events and long-ranged elastic propagation that have been intensively studied in sheared amorphous materials. The pattern of hot-spots progressively coarsens, with the hot-spot size and separation slowly growing over time, and the associated velocity correlation length increasing as a sublinear power law. Each individual spot however exists only transiently, within an overall picture of strongly intermittent dynamics.

description: This thesis handles fundamental problems faced by retailers everyday: how do consumers make choices from an enormous variety of products? How to design a product portfolio to maximize the expected profit given consumers’ choice behavior? How to frame products if consumers’ choices are influenced by the display location? We solve those problems by first, constructing mathematical models to describe consumers’ choice behavior from a given offer set, i.e., consumer choice models; second, by designing efficient algorithms to optimally select the product portfolio to maximize the expected profit, i.e., assortment optimization. This thesis consists of three main parts: the first part solves assortment optimization problem under a consideration set based choice model proposed by Manzini and Mariotti (2014) [Manzini, Paola, Marco Mariotti. 2014. Stochastic choice and consideration sets. Econometrica 82(3) 1153-1176.]; the second part proposes an approximation algorithm to jointly optimize products’ selection and display; the third part works on optimally designing a product line under the Logit family choice models when a product’s utility depends on attribute-level configurations.

description: While the properties of wurtzite GaAs have been extensively studied during the past decade, little is known about the influence of the crystal polytype on ternary (In,Ga)As quantum well structures. We address this question with a unique combination of correlated, spatially-resolved measurement techniques on core-shell nanowires that contain extended segments of both the zincblende and wurtzite polytypes. Cathodoluminescence hyperspectral imaging reveals a blueshift of the quantum well emission energy by $75\pm15$ meV in the wurtzite polytype segment. Nanoprobe x-ray diffraction and atom probe tomography enable $\mathbf{k}\cdot\mathbf{p}$ calculations for the specific sample geometry to reveal two comparable contributions to this shift. First, there is a 30% drop in In mole fraction going from the zincblende to the wurtzite segment. Second, the quantum well is under compressive strain, which has a much stronger impact on the hole ground state in the wurtzite than in the zincblende segment. Our results highlight the role of the crystal structure in tuning the emission of (In,Ga)As quantum wells and pave the way to exploit the possibilities of three-dimensional bandgap engineering in core-shell nanowire heterostructures. At the same time, we have demonstrated an advanced characterization toolkit for the investigation of semiconductor nanostructures.

description: This paper proposes a deep learning-based denoising method for noisy low-dose computerized tomography (CT) images in the absence of paired training data. The proposed method uses a fidelity-embedded generative adversarial network (GAN) to learn a denoising function from unpaired training data of low-dose CT (LDCT) and standard-dose CT (SDCT) images, where the denoising function is the optimal generator in the GAN framework. This paper analyzes the f-GAN objective to derive a suitable generator that is optimized by minimizing a weighted sum of two losses: the Kullback-Leibler divergence between an SDCT data distribution and a generated distribution, and the $\ell_2$ loss between the LDCT image and the corresponding generated images (or denoised image). The computed generator reflects the prior belief about SDCT data distribution through training. We observed that the proposed method allows the preservation of fine anomalous features while eliminating noise. The experimental results show that the proposed deep-learning method with unpaired datasets performs comparably to a method using paired datasets. A clinical experiment was also performed to show the validity of the proposed method for noise arising in the low-dose X-ray CT.

description: Recently I proposed a new calculation scheme of a partition function of an immersion object using path integral method and theory of soliton (to appear in J.Phys.A). I applied the scheme to problem of elastica in two-dimensional space and Willmore surface in three dimensional space. In this article, I will apply the scheme to elastica in three dimensional space as a more physical model in polymer science. Then orbit space of the nonlinear Schrodinger and complex modified Korteweg-de Vries equations can be regarded as the functional space of the partition function. By investigation of the partition function, I gives a conjecture of the relation of these soliton equations.

description: The original casting of the Brunswick Castle Lion of 1166 is somewhat different in its chemical composition from a repairing found in the back of the statue. Both the alloys are red brass, one consisting of 10,3% Sn, 3,7% Pb, 8,9% Zn, the other one of 6,8% Sn, 2,6% Pb, 8,6% Zn. The structure observed in the original casting is explained as a special development of the eutectoid ([alpha] + [delta]), arising from a very slow cooling of the casting. The structure of the repairing corresponds to that of a fast solidified alloy.

Whilst the micromaser has long been recognised as an important model for the dynamics of open quantum systems far from equilibrium, so-called Josephson-photonics devices are a recently developed form of superconducting quantum circuit in which the quantum transport of charges through a voltage-biased Josephson junction drives the production of photons in a microwave resonator.

description: We present an analysis of different sets of gravitational N-body simulations, all describing the dynamics of discrete particles with a small initial velocity dispersion. They encompass very different initial particle configurations, different numerical algorithms for the computation of the force, with or without the space expansion of cosmological models. Despite these differences we find in all cases that the non-linear clustering which results is essentially the same, with a well-defined simple power-law behaviour in the two-point correlations in the range from a few times the lower cut-off in the gravitational force to the scale at which fluctuations are of order one. We argue, presenting quantitative evidence, that this apparently universal behaviour can be understood by the domination of the small scale contribution to the gravitational force, coming initially from nearest neighbor particles.

description: A quantum magnetic impurity of spin $S$ at the edge of a two-dimensional time reversal invariant topological insulator may give rise to backscattering. We study here the shot noise associated with the backscattering current for arbitrary $S$. Our full analytical solution reveals that for $S>\frac{1}{2}$ the Fano factor may be arbitrarily large, reflecting bunching of large batches of electrons. By contrast, we rigorously prove that for $S=\frac{1}{2}$ the Fano factor is bounded between $1$ and $2$, generalizing earlier studies.

description: An increased demand for reclamation using native plants in British Columbia has created opportunities for stable, long-term economic opportunities in Aboriginal communities through employment in native plant horticulture. The Growing our Futures: Native Plant Horticulture training program was created collaboratively by staff at Royal Roads University, Keefer Ecological Services Ltd, West Moberly First Nations and Saulteau First Nations in order to provide training to Aboriginal communities in native plant seed collection, propagation and nursery management. The program was piloted in 2013 at Twin Sisters Native Plant Nursery located in West Moberly BC, and Tipi Mountain Native Plants located in Cranbrook, BC. Nine students from Twin Sisters nursery and seven students from Tipi Mountain nursery completed the Growing our Futures program. Following consultation with the leadership and other representatives of Saulteau and West Moberly First Nations, it was determined that Growing Our Futures should be developed for community-based delivery to support broad student participation, retention and success through enabling students to learn within their family, community and Elders support networks. In this paper, we provide an overview of the 2013 pilot year of the Growing our Futures: Native Plant Horticulture training program, discuss successes and lessons learned, and describe future directions for this program in 2014 and beyond.

description: Using transient grating spectroscopy, we measure thermal diffusivity and surface acoustic wave speed in tungsten exposed to different fluences of deuterium plasma. Scanning electron microscopy (SEM) shows the formation of surface blisters that have similar morphology for all fluences. A significant reduction in thermal diffusivity and surface acoustic wave speed occurs as a result of plasma exposure. A saturation of the thermal diffusivity reduction with fluence is seen. Deuterium ion flux density appears play a more important role in the thermal diffusivity reduction than the fluence. These results have important implications for plasma facing components in future fusion reactors.

Professional Learning Communities (PLCs) as a Means for School-Based Science Curriculum change

description: The challenge of school-based science curriculum change and educational reform is often presented to science teachers and departments who are not necessarily prepared for the complexity of considerations that change movements require. The development of a Professional Learning Community (PLC) focused on a science department's curriculum change efforts, may provide the necessary tools to foster sustainable school-based curriculum science changes. This research presents a case study of an evolving science department PLC consisting of 10 middle school science teachers from the same middle school and their efforts of school-based science curriculum change. A transformative mixed model case study with qualitative data and deepened by quantitative analysis, was chosen to guide the investigation. Collected data worked to document the essential developmental steps, the occurrence and frequency of the five essential dimensions of successful PLCs, and the influences the science department PLC had on the middle school science department's progression through school-based science curriculum change, and the barriers, struggles and inhibiting actions of the science department PLC. Findings indicated that a science department PLC was unique in that it allowed for a focal science departmental lens of science curriculum change to be applied to the structure and function of the PLC and therefore the process, proceedings, and results were directly aligned to and driven by the science department. The science PLC, while logically difficult to set-up and maintain, became a professional science forum where the middle school science teachers were exposed to new science teaching and learning knowledge, explored new science standards, discussed effects on student science learning, designed and critically analyzed science curriculum change application. Conclusions resulted in the science department PLC as an identified tool providing the ability for science departmental actions to lead to outcomes of science curriculum change improvements with the consideration but not the dictation of the larger school community and state agendas. Thus, the study's results work to fuse previously separated research on general PLCs and curriculum change efforts into a cohesive understanding of the unexplored potential of a science PLC and school-based science curriculum change.

description: This paper presents a new method for shadow removal using unpaired data, enabling us to avoid tedious annotations and obtain more diverse training samples. However, directly employing adversarial learning and cycle-consistency constraints is insufficient to learn the underlying relationship between the shadow and shadow-free domains, since the mapping between shadow and shadow-free images is not simply one-to-one. To address the problem, we formulate Mask-ShadowGAN, a new deep framework that automatically learns to produce a shadow mask from the input shadow image and then takes the mask to guide the shadow generation via re-formulated cycle-consistency constraints. Particularly, the framework simultaneously learns to produce shadow masks and learns to remove shadows, to maximize the overall performance. Also, we prepared an unpaired dataset for shadow removal and demonstrated the effectiveness of Mask-ShadowGAN on various experiments, even it was trained on unpaired data.

description: In this paper general directives are developed for the improvement of accumulators, which use compressed air (or a gas which is chemically passive against metals and moisture) as working substance or only as an elastic link. In the second case water serves as working liquid the surface of which is loaded with an air cushion. In each case the storing capacity is caused by a change of pressure in connection with a constant volume.
At first the equations for the calculation of the stored energy are developed in the adiabatic and the isothermal condition, that is for the two limiting cases. Then it is shown that the expenditure of iron for the pressure vessels with a prescribed volume does not depend on the diameter or whether the given volume consists of one or more containers. The same applies to the energy which can be stored per kp of the container material. For the compressed-air accumulator this exploitation of the weight raises steadily with the accumulator pressure up to about 40 kp/cm^2. But it is remarkable that the energy which may be stored per kg of material is practically independent on the pressure if the accumulator is operated with water under compressed gas. In this case there exists also an optimal proportion for the discharge, that is the proportion of the highest to the lowest pressure in the accumulator, of e = 2,718 But the expenditure of material per energy unit for this accumulator is much higher than for the one operated with compressed air only, because the water which does not store energy demands a considerable part of the volume of the tank. But the efficiency is very good and considerably higher than for the accumulator operated with compressed air. Besides that the operation is much simpler, because it is not necessary to cool at charging and to heat at discharging the accumulator. It is even possible to come near to 100% efficiency if one approaches to isothermal change of state in the air cushion by means of heat exchange between air and water volume. That is also possible if one separates the volumes for air and water and connects them by heat exchangers in the junction.

We give criterion for semistability and stability of system of Hodge bundles on $X$. We define notion of generalized opers on $X$, and prove semistability of the Higgs bundle associated to generalized opers. We also show that existence of partial oper structure on a vector bundle $E$ together with a connection $\nabla$ over $X$ implies semistability of the pair $(E, \nabla)$.

description: When war conditions forced Sweden into the position to produce oil on her own, plants were erected at Kvarntorp in 1942, to make use of the immense local ledges of oil shale supplying 4,5% to 6,5% oil. The financia1 side of oil production was thus of minor importance. The investments were 81.000.000 sv. kr, the subsidies ran up to 33.000.000 sv. kr before oil imports were taken up again in 1946. By that time 220000 cbm oil at a net cost of .52 kr per litre had been produced. Since then the investment was raised by 22.000.000 kr. Further technical improvements promise an annual profit of 1.000.000·kr in spite of the reduced sales price of .10 kr per litre fuel oil resp. .16 kr per litre petrol. This unique success was only possible by still continuing improvements of the oil production methods and the development of coordinated industries for various kinds of by-products. Summing up the present author reports upon the composition and the hauling of the oil shale, the different systems of furnaces, the oil extraction "in situ" according to Ljungström, the coking plant, the lime kilns, the utilization of the pyrolysis gas, the light-petrol plant, the fuel and the refining plant. He gives a critical comparison on these different methods. Then he discusses as main products the oil, the white spirit and the Diesel-oil fraction, the heavy oil,the hydrogenation, the catalytic desulphuration, and the ash. As by-products he refers to the light concrete, the bricks, the cement, and the pyrolysis gas. The two last sections deal with the research and the economy .

description: We present a finite difference version of the eth formalism, which allows use of tensor fields in spherical coordinates in a manner which avoids polar singularities. The method employs two overlapping stereographic coordinate patches, with interpolations between the patches in the regions of overlap. It provides a new and effective computational tool for dealing with a wide variety of systems in which spherical coordinates are natural, such as the generation of radiation from an isolated source. We test the formalism with the evolution of waves in three spatial dimensions and the calculation of the curvature scalar of arbitrarily curved geometries on topologically spherical manifolds. The formalism is applied to the solution of the Robinson-Trautman equation and reveals some new features of gravitational waveforms in the nonlinear regime.

Production Planning with Risk Hedging

Production planning

description: We study production planning integrated with risk hedging in a continuous-time stochastic setting. The (cumulative) demand process is modeled as a sum of two components: the demand rate is a general function in a tradable financial asset (which follows another stochastic process), and the noise component follows an independent Brownian motion. There are two decisions: a production quantity decision at the beginning of the planning horizon, and a dynamic hedging strategy throughout the horizon. Thus, the total terminal wealth has two components: production payoff, and profit/loss from the hedging strategy.
      The production quantity and hedging strategy are jointly optimized under the mean-variance and the shortfall criteria. For each risk objective, we derive the optimal hedging strategy in closed form and express the associated minimum risk as a function of the production quantity, the latter is then further optimized. With both production and hedging (jointly) optimized, we provide a complete characterization of the efficient frontier. By quantifying the risk reduction contributed by the hedging strategy, we demonstrate its substantial improvement over a production-only decision.
      To derive the mean-variance hedging strategy, we use a numeraire-based approach, and the derived optimal strategy consists of a risk mitigation component and an investment component. For the shortfall hedging, a convex duality method is used, and the optimal strategy takes the form of a put option and a digital option, which combine to close the gap from the target left by production (only).
      Furthermore, we extend the models and results by allowing multiple products, with demand rates depending on multiple assets. We also make extension by allowing the asset price to follow various stochastic processes (other than the geometric Brownian motion).

description: It is shown that the eddy currents in the rotor of an induction machine produce a torque proportional to the slip according to the general relations between torque, electrical rotor power and mechanical power. This torque can be dealt with in the same way as the torque of the rotor currents, the same torque producing flux being influencing both. Conditions are quite different for the rotor hysteresis, the rotor hysteresis torque being constant and only reversing its sign in synchronisme. This power jump, the hysteresis jump, means an alteration of the direction of energy flow through the air gap of the induction machine without load. It was found that the ratio of the total rotor iron losses to air gap power of the eddy currents and hysteresis is equal to the slip, in analogy to the well known relations between slip, electrical rotor power and air gap power of a loaded induction machine. In a table and several figures the conditions are illustrated as a function of slip.
It is shown how the circle diagram must be altered as a result of the reflexions. The diameter of the circle remains constant but direction and size of no load current in synchronisme will be altered. The eddy currents of the rotor alter the short circuit point and the power line while the hysteresis torque causes a parallel shift of the torque line (to the bottom in case of subsynchronisme, and to the top in case of hypersynchronisme) whereby the bearing friction loss may be included. The mechanical useful power of the motor or the driving power of the generator respectively is found by the diagram and simple calculation.

description: We measured the effective diffusion coefficient in regions of microfluidic networks of controlled geometry using the FRAP (Fluorescence Recovery After Photobleaching) technique. The geometry of the networks was based on Voronoi tessellations, and had varying characteristic length scale and porosity. For a fixed network, FRAP experiments were performed in regions of increasing size. Our results indicate that the boundary of the bleached region, and in particular the cumulative area of the channels that connect the bleached region to the rest of the network, are important in the measured value of the effective diffusion coefficient. We found that the statistical geometrical variations between different regions of the network decrease with the size of the bleached region as a power law, meaning that the statistical error of effective medium approximations decrease with the size of the studied medium, although no characteristic length scale could be defined over which the porous medium is equivalent to an effective medium.

description: Given a partition $\la = (\la_1, \la_2, ... \la_k)$, let $\la^{rc} = (\la_2-1, \la_3-1, ... \la_k-1)$. It is easily seen that the diagram $\la\slash \la^{rc}$ is connected and has no $2 \times 2$ subdiagrams which we shall refer to as a ribbon. To each ribbon $R$, we associate a symmetric function operator $S^R$. We may define the major index of a ribbon $maj(R)$ to be the major index of any permutation that fits the ribbon. This paper is concerned with the operator $H_{1^k}^q = \sum_R q^{maj(R)} S^R$ where the sum is over all $2^{k-1}$ ribbons of size $k$. We show here that $H_{1^k}^q$ has truly remarkable properties, in particular that it is a Rodriguez operator that adds a column to the Hall-Littlewood symmetric functions. We believe that some of the tools we introduce here to prove our results should also be of independent interest and may be useful to establish further symmetric function identities.

description: As contrasted with the Celtic coins, on which the Greek models are liberally transformed, the coinage of the German empires of the great migration of people on the ground of the Roman empire remain entirely dependant on the images on coins from the time of the late Roman emperors. This is a fact among the Ostrogoths, the Vandals in Africa and the Langobards in Italy. On the Langobards' coins the contrary between the style of their plastic art and their ornaments and the permanent imitations of Roman coins is specially striking. In spite of all efforts to create own coinage, the Visigoths in Spain have also not been able to emancipate completely from ancient models. The same is to be said about the Franc in Gaul, whose continually more and more deformed imitations are reaching as far as into the eight century. Besides the coins, there are, especially among the North Germans, the coin-like golden jewel-bracteates, which are completely covered with a phantastic ornamentation of animals and plaited ribbons. On coins we find similar patterns only among the Anglosaxons and in the Viking settlement of Haithabu (Hedeby) in Schleswig.

description: The environmental overview of Uzbekistan highlights significant challenges and ecological issues facing the country. Uzbekistan's environmental landscape is characterized by various problems, including water scarcity, soil degradation, air pollution, biodiversity loss, and deforestation. The depletion of the Aral Sea due to unsustainable water management practices has had severe environmental and socio-economic consequences, leading to the emergence of ecological disasters and public health concerns. Additionally, industrial activities and agricultural practices contribute to environmental pollution and habitat destruction. This annotation explores the complex interplay between environmental problems and ecological degradation in Uzbekistan, emphasizing the urgent need for sustainable environmental management and conservation efforts to mitigate these challenges.

description: We investigate the dynamics of an overdamped Brownian particle moving in a washboard potential with space dependent friction coefficient. Analytical expressions have been obtained for current and diffusion coefficient. We show that the effective diffusion coefficient can be enhanced or suppressed compared to that of the uniform friction case. The diffusion coefficient is maximum near the critical threshold ($F_{c}$), which is sensitive to temperature and the frictional profile. In some parameter regime we observe that increase in noise (temperature) decreases the diffusion, which is counter-intuitive. This leads to coherent transport with large mean velocity accompanied by small diffusion. This is shown explicitly by analysis of Péclet number, which has been introduced to study coherent or optimal transport. This phenomena is complementary to giant diffusion.

description: We extend the recently developed technique of opto-optical modulation (OOM) to probe state-resolved ac-Stark-induced phase variations of a coherently excited ensemble of helium atoms. In a joint experimental and theoretical study, we find that the spatial redirection of the resonant emission from the OOM process is different for the low-lying 1s2p state as compared with the higher-lying Rydberg states, and that this redirection can be controlled through the spatial characteristics of the infrared (IR) probe beam. In particular, we observe that the intensity dependence of the IR-induced Stark phase on the 1s2p emission is nonlinear, and that the phase accumulation changes sign for moderate intensities. Our results suggest that OOM, combined with precise experimental shaping of the probe beam, could be used to measure the Stark-induced phase shifts of excited states.
