description: Prior work demonstrated the potential of using the Linear Predictive Coding (LPC) filter to approximate muscle stiffness and damping from computer mouse movements to predict acute stress levels of users. Theoretically, muscle stiffness and damping in the arm can be estimated using a mass-spring-damper (MSD) biomechanical model. However, the damping frequency (i.e., stiffness) and damping ratio values derived using LPC were not yet compared with those from a theoretical MSD model. This work demonstrates that the damping frequency and damping ratio from LPC are significantly correlated with those from an MSD model, thus confirming the validity of using LPC to infer muscle stiffness and damping. We also compare the stress level binary classification performance using the values from LPC and MSD with each other and with neural network-based baselines. We found comparable performance across all conditions demonstrating LPC and MSD model-based stress prediction efficacy, especially for longer mouse trajectories. Clinical relevance: This work demonstrates the validity of the LPC filter to approximate muscle stiffness and damping and predict acute stress from computer mouse movements.

description: The compounds A$_2$Cu$_3$O(SO$_4$)$_3$ (A=Na, K) are characterized by copper hexamers which are weakly coupled to realize antiferromagnetic order below TN=3 K. They constitute novel quantum spin systems with S=1 triplet ground-states. We investigated the energy-level splittings of the copper hexamers by inelastic neutron scattering experiments covering the entire range of the magnetic excitation spectra. The observed transitions are governed by very unusual selection rules which we ascribe to the underlying spin-coupling topology. This is rationalized by model calculations which allow an unambiguous interpretation of the magnetic excitations concerning both the peak assignments and the nature of the spin-coupling parameters.

Signals regulating neuronal cell body responses to axotomy
Creators: name: Fernandes, Karl John Lionel
Publisher: name: University of British Columbia
Year: 2009

description: Spinal cord injury in higher vertebrates causes paralysis because injured neurons in the adult central nervous system (CNS) often atrophy or die, and fail to regenerate their severed processes ("axons"). In contrast, injured peripheral nervous system (PNS) neurons usually survive and regenerate their axons. One reason for successful PNS responses to axon injury ("axotomy") is that they undergo numerous changes in gene expression that enhance their intrinsic growth state. These changes include the upregulation of proteins required for axon growth, and down-regulation of non-essential proteins, such as those used mainly for neurotransmission. Similar changes in gene expression are generally only weak and transient in axotomized CNS neurons, which most likely contributes to their poor responses to injury. This thesis investigates the potential regulation of injury-induced changes in gene expression by neurotrophic factors (NTFs), small proteins important for development and maintenance of the nervous system. Three principal findings are presented here. Firstly, in axotomized PNS motoneurons, the down-regulation of non-essential proteins associated with neuronal maturation, such as neurotransmitter enzymes and neurofilaments appears to be due to the interrupted supply of target-derived neurotrophic factors. Secondly, in axotomized PNS. motoneurons, the robust up-regulation of regeneration-associated genes and cell body hypertrophy is enhanced by non-targetderived neurotrophic factors, most likely those released by Schwann cells and immune cells at the actual site of injury. In fact, a second axon injury (to stimulate release of these endogenous neurotrophic factors) was sufficient to actually reverse the severe cell body atrophy and up-regulate the regeneration-associated gene expression of chronically axotomized motoneurons. Thirdly, when exogenous neurotrophic factors were used to supplement a CNS spinal cord lesion site, which does not contain Schwann cells and has only limited invasion of immune cells, the regenerative cell body responses of axotomized CNS rubrospinal neurons were greatly enhanced. These findings provide insights into the signals regulating neuronal gene expression after injury, and identify neurotrophic factors at the site of axotomy as an important determinant of a neuron's regenerative response to injury.

description: The choice of variety is one of the most important decisions made when growing soybeans. Choosing the right variety creates the conditions for high added value through high (and reliable) yields of grain of adequate quality. Attention to the specific quality attributes of a variety can attract high prices in specialised markets. Other attributes of the variety, can help reduce production costs. European farmers have a wide range of soybean varieties to choose from. The optimum choice depends primarily on the latitude, local growing conditions and the intended market or use of the soybean.

description: Commingling cattle in the feedlot increases the odds of cattle getting sick. However, backgrounded cattle are less susceptible to diseases which allow the generalizing statements like "backgrounding is just like single source". Using data from over 15,000 cattle fed in 12 Iowa feedlots, we show that although backgrounded cattle do better than preconditioned cattle commingled in the feedlot, they have poorer carcass quality, health, and performance than single source cattle. Backgrounded cattle should be discounted $8.24/head relative to single source, and only received a small premium over multi-source preconditioned cattle though not significantly different.

description: Open Science is a global transition aimed at making scientific research practices more open and collaborative for improved scientific and societal impact, and is globally promoted as the new normal. But practices reflecting the Open Science values, such as sharing results and engaging with stakeholders outside of academia, are not the norm yet, because they are generally not rewarded. Since 2019, Dutch knowledge institutions and research funders have been working together to broaden the recognition of academic work: a position paper was produced, a national recognition and rewards programme was launched, and the international Agreement on Reforming Research Assessment was signed. In April of this year, a next phase kicked off with the publication of a national roadmap defining very concrete steps to implement a new recognition and rewards approach in daily practice.One of the main priorities in the Dutch programme is the focus on quality. Quality assessments will likely involve labor intensive processes that are bound to further increase the workload of academic experts. And even when quality is the focus, metrics that give an insight in the way in which researchers contribute to the various dimensions of an assessment framework will remain relevant. For example, in the radar chart used in communications about balancing the recognition/awards system in The Netherlands, putting data points for contributions to research, education, impact and leadership will require collecting data and deriving metrics from that data.

description: Control modular addition is a core arithmetic function, and we must consider the computational cost for actual quantum computers to realize efficient implementation. To achieve a low computational cost in a control modular adder, we focus on minimizing KQ, defined by the product of the number of qubits and the depth of the circuit. In this paper, we construct an efficient control modular adder with small KQ by using relative-phase Toffoli gates in two major types of quantum computers: Fault-Tolerant Quantum Computers (FTQ) on the Logical layer and Noisy Intermediate-Scale Quantum Computers (NISQ). We give a more efficient construction compared to Van Meter and Itoh's, based on a carry-lookahead adder. In FTQ, $T$ gates incur heavy cost due to distillation, which fabricates ancilla for running $T$ gates with high accuracy but consumes a lot of specially prepared ancilla qubits and a lot of time. Thus, we must reduce the number of $T$ gates. We propose a new control modular adder that uses only 20% of the number of $T$ gates of the original. Moreover, when we take distillation into consideration, we find that we minimize $\text{KQ}_{T}$ (the product of the number of qubits and $T$-depth) by running $Θ\left(n / \sqrt{\log n} \right)$ $T$ gates simultaneously. In NISQ, CNOT gates are the major error source. We propose a new control modular adder that uses only 35% of the number of CNOT gates of the original. Moreover, we show that the $\text{KQ}_{\text{CX}}$ (the product of the number of qubits and CNOT-depth) of our circuit is 38% of the original. Thus, we realize an efficient control modular adder, improving prospects for the efficient execution of arithmetic in quantum computers.

description: This is the first of a series of three papers on clustered star formation in the Rosette Molecular Complex. Here we investigate star formation in the interfacing layers between the expanding Rosette Nebula and its surrounding cloud, based on an analysis of the spatially complete and unbiased 2MASS data. Two medium-mass infrared clusters with ages of around 1 Myr are identified in the south and south-east arcs of the fragmented shell. The majority of the candidate cluster members in these radiation and pressure-confined regions are found to be almost uniformly distributed, roughly following the compression layers traced by the distribution of optical depth at 100 $μ$m, and may well develop into gravitationally unbound systems upon their emergence from the parental cloud. These expanding shells are believed to be playing important roles in impeding the emerging young open cluster NGC 2244 from intruding immediately and deeply into the ambient molecular cloud, where sequential formation of massive clusters is taking place.

description: The optimal hedging model has become the standard theoretical model of normative hedging behavior due to its intuitive tradeoff of expected return with risk, its effcient use of information and its easy implementation. In practice, the model can be easily implemented with the Parameter Certainty Equivalent procedure, which substitutes sample estimates for the true but unknown model parameters. But subjective views, which refer to opinions concerning the directions of market returns of the assets involved in hedging decisions, are either completely ignored or handled in an ad hoc and unsatisfactory manner within the optimal hedging model. Given the widespread use of subjective views in hedging practice and the potential economic benefit of selective hedging, the lack of accommodation of subjective views in the optimal hedging model is a serious problem and could hamper the model's application in risk management practice. With an empirical Bayesian approach adopted, this study proposes an alternative Bayesian optimal hedging model, in which a hedger can adjust his/her optimal hedging position (ratio) according to his/her view(s) on the expected returns of assets under consideration. Like Lence and Hayes' Bayesian optimal hedging model (1994a, 1994b), the optimal hedging position is also determined by mean-variance optimization conditioned on the predictive expectation vector and predictive covariance matrix of asset returns, but unlike their model, the number and type of subjective views that can be expressed is quite flexible because of the adoption of an empirical Bayesian approach. The empirical Bayesian optimal hedging model provides practitioners with a theoretically intuitive yet quantitatively rigorous framework to blend subjective views and the market consensus estimated from sample data according to their relative confidence levels.

description: Synthesizing high dynamic range (HDR) images from multiple low-dynamic range (LDR) exposures in dynamic scenes is challenging. There are two major problems caused by the large motions of foreground objects. One is the severe misalignment among the LDR images. The other is the missing content due to the over-/under-saturated regions caused by the moving objects, which may not be easily compensated for by the multiple LDR exposures. Thus, it requires the HDR generation model to be able to properly fuse the LDR images and restore the missing details without introducing artifacts. To address these two problems, we propose in this paper a novel GAN-based model, HDR-GAN, for synthesizing HDR images from multi-exposed LDR images. To our best knowledge, this work is the first GAN-based approach for fusing multi-exposed LDR images for HDR reconstruction. By incorporating adversarial learning, our method is able to produce faithful information in the regions with missing content. In addition, we also propose a novel generator network, with a reference-based residual merging block for aligning large object motions in the feature domain, and a deep HDR supervision scheme for eliminating artifacts of the reconstructed HDR images. Experimental results demonstrate that our model achieves state-of-the-art reconstruction performance over the prior HDR methods on diverse scenes.

description: We consider a two-dimensional electron system with Coulomb interaction between particles at a finite temperature T. We show that the dynamic Kohn anomaly in the response function at 2K_F leads to a linear-in-T correction to the spin susceptibility, same as in systems with short-range interaction. We show that the singularity of the Coulomb interaction at q=0 does not invalidate the expansion in powers of r_s, but makes the expansion non-analytic. We argue that the linear temperature dependence is consistent with the general structure of Landau theory and can be viewed as originating from the non-analytic component of the Landau function near the Fermi surface.

description: This study was undertaken to update earlier work by the authors that analyzed selected preharvest pricing strategies utilizing options markets to establish a price floor for part of the crop in the spring, with additional pricing done by use of short hedges in early summer. The timing of implementing these strategies was moved back to late February if the previous year's U.S. crop was a weather-induced short crop. A weather-induced short crop as opposed to a government program induced short crop was defined as one in which U.S. production fell below the previous year's use and the U.S. average yield was at least 6% below a trend yield. Previous work by the authors indicated that selected pre-harvest strategies applied to actual farms in Iowa and Ohio over the 1985-1998 time period generated net returns well above those from a naive strategy of systematically selling at harvest, with t-tests indicating statistical significance at the 5% level. Similar results were observed when the time period was extended to 2001. The results from this study may explain the observed increase in the use of forward pricing by farmers, the emergence of new pre-harvest marketing tools focusing on late winter and spring pricing opportunities, and the emphasis on pre-harvest pricing by market advisory services (Irwin et al., 2003). Results reported here suggest that over the past 18 to 29 years, farmers have had the potential to reap substantial economic benefits from improving both their pre-harvest and post-harvest marketing skills.

description: Numerous empirical studies have investigated the profitability of technical trading rules in a wide variety of markets, and many of them found positive profits. Despite positive evidence about profitability and improvements in testing procedures, skepticism about technical trading profits remains widespread among academics mainly due to data snooping problems. This research tries to mitigate the problems by confirming the results of a previous study and then replicating the original testing procedure on new data. Results indicate that for various futures contracts and technical trading systems tested, technical trading profits have gradually declined over time. In general, substantial technical trading profits in the early 1980s are no longer available in the subsequent period.

description: We consider the motion of the end mirror of a cavity in whose standing wave mode pattern atoms are trapped. The atoms and the light field strongly couple to each other because the atoms form a distributed Bragg mirror with a reflectivity that can be fairly high. We analyze how the dipole potential in which the atoms move is modified due to this backaction of the atoms. We show that the position of the atoms can become bistable. These results are of a more general nature and can be applied to any situation where atoms are trapped in an optical lattice inside a cavity and where the backaction of the atoms on the light field cannot be neglected. We analyze the dynamics of the coupled system in the adiabatic limit where the light field adjusts to the position of the atoms and the light field instantaneously and where the atoms move much faster than the mirror. We calculate the side band spectrum of the light transmitted through the cavity and show that these spectra can be used to detect the coupled motion of the atoms and the mirror.

description: Assessment of spontaneous movements can predict the long-term developmental disorders in high-risk infants. In order to develop algorithms for automated prediction of later disorders, highly precise localization of segments and joints by infant pose estimation is required. Four types of convolutional neural networks were trained and evaluated on a novel infant pose dataset, covering the large variation in 1 424 videos from a clinical international community. The localization performance of the networks was evaluated as the deviation between the estimated keypoint positions and human expert annotations. The computational efficiency was also assessed to determine the feasibility of the neural networks in clinical practice. The best performing neural network had a similar localization error to the inter-rater spread of human expert annotations, while still operating efficiently. Overall, the results of our study show that pose estimation of infant spontaneous movements has a great potential to support research initiatives on early detection of developmental disorders in children with perinatal brain injuries by quantifying infant movements from video recordings with human-level performance.

This novel inverse magnetoresistance phenomenon is robust, does not depend on the presence of impurities, and is unique to molecular and atomic nanoscale magnetic junctions. Its physical origin is identified and its relevance to experiment and to potential technological applications is discussed.

Facing the huge pressure brought by factors such as land, transportation and environment, the means of transportation on the ground have long been unable to meet the needs of people in modern cities. Metro is favored by people because of its high speed, stability and large capacity, and has become the best choice to relieve congestion in the public transportation system. How to efficiently use land resources while constructing urban metro systems? This article sorts out the current status of commercial construction in Nanchang metros to study the application value of commercial complex in the metro stations of Nanchang, so as to provide some useful references for related theoretical research.

description: We realize an end-to-end no-switching quantum key distribution protocol using continuous-wave coherent light. We encode weak broadband Gaussian modulations onto the amplitude and phase quadratures of light beams at the Shannon's information limit. Our no-switching protocol achieves high secret key rate via a post-selection protocol that utilizes both quadrature information simultaneously. We establish a secret key rate of 25 Mbits/s for a lossless channel and 1 kbit/s, per 17 MHz of detected bandwidth, for 90% channel loss. Since our scheme is truly broadband, it can potentially deliver orders of magnitude higher key rates by extending the encoding bandwidth with higher-end telecommunication technology.

description: This paper tests the conventional wisdom that U.S. marketing orders act as profit-maximizing cartels. The paper analyzes the marketing order for U.S. almonds in both the domestic and export markets. Such a case study is relevant to all U.S. marketing orders because the size and scope of the U.S. almond industry on the world market, and the legal authority of the almond marketing order makes it a likely prospect for exhibiting true cartel behavior. The authors find that the market power exerted by the Almond Board of California's reserve setting is significantly less than would be expected from a profit-maximizing cartel.

description: Signal digitizers revolutionized the approach to the electronics readout of radiation detectors in Nuclear Physics. These highly specialized pieces of equipment are designed to acquire the signals that are characteristic of the detectors in nuclear physics experiments. The functions of the several modules that were once needed for signal acquisition, can now be substituted by a single digitizer. As suggested by the name, with such readout modules, signals are first digitized (i.e. the signal waveform is sampled and converted to a digital representation) and then either stored or analyzed on-the-fly. The performances can be comparable or better than the traditional analog counterparts, in terms of energy, time resolution, and acquisition rate. In this work, we investigate the use of general-purpose digital oscilloscopes as signal digitizers for nuclear detectors. In order to have a proper comparison, we employ a distributed data acquisition system (DAQ), that standardizes the interface between the hardware and the on-line data analysis. The signals, from a set of typical radiation detectors, are digitized and analyzed with the very same algorithms in order to avoid biases due to different software analysis. We compare two traditional signal digitizers (CAEN DT5725 and CAEN DT5751) to two low-cost digital oscilloscopes (Digilent Analog Discovery 2, and Red Pitaya STEMLab 125-14), in terms of their capabilities for spectroscopy (energy resolution), time resolution, pulse shape discrimination, and maximum acquisition rate.

Participatory evaluation as a tool for enhancing the role of self-help groups in health planning
Creators: name: Campbell, Deborah Lee
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation explores the potential of participatoryevaluation as a tool for involving self-help groups in health promotion. To explore this potential, I engaged twenty-one women representing seventeen women's self-help groups in Vancouver in an exercise to consider how well the Vancouver/Richmond Health Board: (1) included groups such as theirs in a recent community participation process and (2) supported self-help groups as complementary health services. The Health Board was invited but did not become involved. On the whole, participants perceived that the Health Board adopted a top-down approach to community health promotion and did not include or support their groups adequately or equitably. They believed that the Health Board had failed to develop a sense of trust and camaraderie between the Board and self-help groups and that the Board's efforts to reach out to these groups did not involve planning approaches that fostered such relations. This dissertation reveals that it is not necessary to have to choose between a consensus and conflict approach to participatory evaluation. Evaluation can be placed on a continuum ranging from one extreme to the other and can adopt elements of both forms of evaluation. The grass-roots, flexible nature of our exercise enabled participants to conduct the evaluation using either or both of these stances. Our exercise was more consensus-oriented but also involved elements of the conflict approach. The nonattendance of the Health Board gave participants the opportunity and confidence to organize, to take control, to become empowered, and to act. This absence, however, made it difficult for self-helpers to work collaboratively with the Health Board during the evaluation and to share understandings and reach a consensus with them about our findings and how they can be used to make transformations in health promotion. On the other hand, our exercise enabled participants to find alternative ways to work with the Health Board in the future. In other words, we adopted an incremental rather than revolutionary strategy and, therefore, may have only temporarily compromised educative authenticity to achieve catalytic and tactical authenticity.

description: We have studied constraints on the equation of state, $w$, and speed of sound, c_s, of the dark energy from a joint analysis of data from the cosmic microwave background, large scale structure and type-Ia supernovae. We find that current observations have no significant sensitivity to c_s. However, there is a slight difference between models in which there are no dark energy perturbations and models in which dark energy behaves as a fluid. Assuming that there are no dark energy perturbations shifts the allowed region for $w$ to slightly higher values. At present models with and without dark energy perturbations provide roughly equally good fits to observations, but the difference is potentially important for future parameter estimations. Finally, we have also performed error forecasts for future measurements of c_s.

description: Many countries require labeling for GM food products. These countries often have different levels of genetic modification that they will tolerate before a food product must be labeled as genetically modified. For example, the European Union and Australia allow up to one percent of any ingredient in a food product to be GM before the product must be labeled as genetically modified. Japan allows 5% of any ingredient to be genetically modified before the product must be labeled as such. The United States currently does not require mandatory labeling of GM labeled foods and has no standards for what percentage of an ingredient in a food product can be genetically modified for the product to still be labeled non-GM. For the official "organic" certification by the United States, a food product must be genetically modified and there is no tolerance for any genetically modified content. This paper presents empirical evidence on consumers' value for non-GM foods that are certified to have no GM content and non-GM foods that could have ingredients that were up to one or five percent genetically modified. We estimate values using a laboratory auction experiment performed on 44 randomly chosen adult consumers in the Des Moines, IA, area, grouped in 3 experimental units. They participated in a random nth-price auction experiment, in which they bid on three familiar neutral food items that may be genetically modified. Using statistical design and econometric analysis, this paper will estimate the average value of tolerance levels to consumers, measured as the difference in the auction price of a certified non-GM food and a non-GM food that had a tolerance of one or five percent. This paper has two findings. We find evidence indicating consumers place value in a certified non-GM food product, as opposed to a non-GM food product with a tolerance. We find no evidence, however, that consumers value a product with a tolerance of one percent more than they value a product with a tolerance of five percent. Due to decreased firm costs of complying with a tolerance of five percent, we find evidence that if the United States decides to enact a tolerance standard, a five percent tolerance may be better than a one percent tolerance. This information could be useful to policy makers who are considering whether to write in an acceptable tolerance level for genetically modified material.

description: We offer a decentralized solution to the asymmetric information and hidden action problems in the nonpoint source (NPS) pollution case. Farmers in the same watershed generate homogeneous NPS pollution. The regulator, R, pays for (or represents a group of point-source, PS, polluters who pay for) pollution reduction credits earned by the group of the farmers. To resolve the asymmetric information problem, R is concerned with only the total level of the abatement achieved, while the group of farmers (called the Association, A), undertakes responsibility to distribute the payment so as to induce farmers to deliver abatement. We show that A can devise an optimal contract to deal with the farmers' hidden action problem. We identify the restrictions under which such a policy can be implemented, evaluate its effects on the product market, and show that in the NPS case information rents are higher than in the PS case.

description: Averting the effects of anthropogenic climate change requires a transition from fossil fuels to low-carbon technology. A way to achieve this is to decarbonize the electricity grid. However, further efforts must be made in other fields such as transport and heating for full decarbonization. This would reduce carbon emissions due to electricity generation, and also help to decarbonize other sources such as automotive and heating by enabling a low-carbon alternative. Carbon taxes have been shown to be an efficient way to aid in this transition. In this paper, we demonstrate how to to find optimal carbon tax policies through a genetic algorithm approach, using the electricity market agent-based model ElecSim. To achieve this, we use the NSGA-II genetic algorithm to minimize average electricity price and relative carbon intensity of the electricity mix. We demonstrate that it is possible to find a range of carbon taxes to suit differing objectives. Our results show that we are able to minimize electricity cost to below \textsterling10/MWh as well as carbon intensity to zero in every case. In terms of the optimal carbon tax strategy, we found that an increasing strategy between 2020 and 2035 was preferable. Each of the Pareto-front optimal tax strategies are at least above \textsterling81/tCO2 for every year. The mean carbon tax strategy was \textsterling240/tCO2.

description: With the aging of the social population, community care has become another important care model between home care and institutional care. In order to fully understand the social cognition and demand of "Internet + community care", the project team conducted a questionnaire survey in accordance with the research objectives. The survey concluded that the public are still dependent on the traditional care, and do not know much about "Internet + community care", but are willing to try. "Internet + community care" can not only enrich and innovate the care model, but also effectively solve the problems of limited pension resources and mismatch between supply and demand, which is conducive to promoting the realization of high-quality and efficient services for the aged.

description: Rare earth triangular lattice materials have been proposed as a good platform for the investigation of frustrated magnetic ground states. KErSe$_2$ with the delafossite structure, contains perfect two-dimensional Er$^{3+}$ triangular layers separated by potassium ions, realizing this ideal configuration and inviting study. Here we investigate the magnetism of KErSe$_2$ at miliKelvin temperatures by heat capacity and neutron powder diffraction. Heat capacity results reveal a magnetic transition at 0.2 K in zero applied field. This long-range order is suppressed by an applied magnetic field of 0.5 T below 0.08 K. Neutron powder diffraction suggests that the zero-field magnetic structure orders with $k=(\frac{1}{2},0,\frac{1}{2})$ in a stripe spin structure. Unexpectedly, Er is found to have a reduced moment of 3.06(1) $μ_B$/Er in the ordered state and diffuse magnetic scattering, which originates at higher temperatures, is found to persist in the ordered state potentially indicating magnetic fluctuations. Neutron diffraction collected under an applied field shows a metamagnetic transition at $\sim$ 0.5 T to ferromagnetic order with $k$=(0,0,0) and two possible structures, which are likely dependent on the applied field direction. First principle calculations show that the zero field stripe spin structure can be explained by the first, second and third neighbor couplings in the antiferromagnetic triangular lattice.

description: The dispersion properties of exciton polaritons in multiple-quantum-well based resonant photonic crystals are studied. In the case of structures with an elementary cell possessing a mirror symmetry with respect to its center, a powerful analytical method for deriving and analyzing dispersion laws of the respective normal modes is developed. The method is used to analyze band structure and dispersion properties of several types of resonant photonic crystals, which would not submit to analytical treatment by other approaches. These systems include multiple quantum well structures with an arbitrary periodic modulation of the dielectric function and structures with a complex elementary cell. Special attention was paid to determining conditions for superradiance (Bragg resonance) in these structures, and to the properties of the polariton stop band in the case when this condition is fulfilled (Bragg structures). The dependence of the band structure on the angle of propagation, the polarization of the wave, and the effects due to exciton homogeneous and inhomogeneous broadenings are considered, as well as dispersion properties of excitations in near-Bragg structures.

description: Three distinct types of behaviour have recently been identified in the two-dimensional trapped bosonic gas, namely; a phase coherent Bose-Einstein condensate (BEC), a Berezinskii-Kosterlitz-Thouless-type (BKT) superfluid and normal gas phases in order of increasing temperature. In the BKT phase the system favours the formation of vortex-antivortex pairs, since the free energy is lowered by this topological defect. We provide a simple estimate of the free energy of a dilute Bose gas with and without such vortex dipole excitations and show how this varies with particle number and temperature. In this way we can estimate the temperature for cross-over from the coherent BEC to the (only) locally ordered BKT-like phase by identifying when vortex dipole excitations proliferate. Our results are in qualitative agreement with recent, numerically intensive, classical field simulations.
