description: Auctioning off goods is a widespread practice in the agricultural sector. The revenue equivalence theorem predicts that independent of the type of auction, the revenues are identical under fulfillment of specific conditions. One of these conditions is that bidders must be risk neutral; this condition, however, often fails in reality. An experiment was carried out with farmers to investigate how the bid amount is influenced by the individual risk attitude. In the experiment, farmers were able to buy a good with a private value in four different auctions types. Results indicate that the revenues in auctions are affected by the risk attitude of the bid-ders. Moreover, the influence of the risk attitude depends on the auction type.
title: Orientation-Invariant ECG-Based Virtual Pathology Stethoscope Tracking for Standardized Patient Heart Auscultation

description: Cardiac auscultation (CA), the act of listening to the heart sounds, is a critical physician's skill that provides substantial information for diagnosing many cardiovascular disorders; therefore, competent training can be a key for accurate and reliable diagnosis. The teaching of CA has been an area of recognized importance since the inception of the stethoscope. However, recent changes in health-care, such as limited student access to patients and higher reliance on competing technologies have made it challenging to teach bedside CA techniques.

Over the past few decades, standardized patients (SPs), individuals trained to portray real patients, have been widely used for such training, thereby overcoming the problem of waiting for suitable real patients. However, SPs are typically healthy individuals and rarely exhibit the same abnormal CA findings as their attributed disorders. This limits the range and variety of symptoms that can be demonstrated to medical students.

This thesis seeks to improve the CA skills of medical students by virtual pathology simulation that utilizes modified stethoscopes (virtual pathology stethoscopes) in tandem with standardized patients. In this work, we describe a novel orientation-invariant stethoscope tracking method for placing virtual symptoms in correct auscultation areas based on recorded electrocardiogram (ECG) signals. This would extend the capabilities of SPs and allow trainees to perform realistic CA and hear abnormal heart or lung sounds in otherwise healthy patient actors.

Recorded ECG signals of two different SPs with a wide range of the stethoscope's chest piece orientations were processed from four CA regions. After processing the signals and extracting proper features, different classifiers were applied for assessment of the proposed tracking method- 95% and 87% accuracy was obtained for SPl and SP2, respectively. These findings suggest that the system is invariant to the stethoscope's chest piece orientation and can accurately distinguish the different auscultation areas. The proposed system provides an efficient and cost-effective method for tracking virtual pathology stethoscopes which can be used in training medical practitioners on proper heart auscultation.

description: Starburst galaxies generate large-scale winds powered by the activity in the star-forming regions located in the galactic disks. Fragmentation of the disk produced by the outbreak of the wind results in the formation of clouds. Bowshocks caused by the supersonic outflow appear around such clouds. In this paper we discuss the acceleration of relativistic particles and the production of non-thermal radiation in such scenario. Cosmic rays accelerated at the bowshocks do not reach the highest energies, although the high-energy luminosity generated is significant. We show that up to ~10% of the gamma-ray emission in starbursts might come from these sources outside the galactic disks. Discrete X-ray sources with a power-law component are also expected.

description: The Lanchester model of strategic interaction typically considers only two-firm rivalry and one strategic tool. This paper presents an alternative that considers rivalry among several firms using multiple tools. Marketing decisions are dynamically optimal and use equations of motion for market share that are consistent with optimal consumer choice. Using a single-market case study that consists of five years of monthly data on ready to eat cereal sales, advertising, product development investments and new product introductions, we test our model against a similar Lanchester specification. Non-nested specification tests fail to reject the proposed model, but reject the Lanchester alternative.

We analyze such a situation in the framework of the non-linear relativity schemes recently proposed by Magueijo and Smolin. We finally examine the experimental implications of our theoretical proposals by considering the spectrum and the end-point of beta decay in tritium.

description: Boekhoutia Q.M. Wang & F.Y. Bai gen. nov. MycoBank MB828807.
 Etymology: the genus is named in honour of Dr. Teun Boekhout for his research contributions to yeast taxonomy.
 This genus is proposed for the branch represented by strain CGMCC 2.4539, which formed a separate clade from Kurtzmanomyces. Member of the Chionosphaeraceae (Agaricostilbales). The genus is mainly circumscribed by the phylogenetic analysis of the seven genes dataset, in which it occurred as a separate branch within Chionosphaeraceae (Fig. 4A).
Sexual reproduction not known. Colonies orange red, butyrous. Budding cells present and blastoconidia produced at the end of a stalk-like conidiophore. Conidiophore single or multiple, usually multifurcate. Pseudohyphae and hyphae not produced. Ballistoconidia formed.
 Type species: Boekhoutia sterigmata Q.M. Wang, F.Y. Bai & A.H. Li.
 Note: Boekhoutia and its close relative Kurtzmanomyces can produce stalk-like conidiophores, the former usually produces multifurcate conidiophores; each conidiophore of the latter can produce sequential multiple blastoconidia (Sampaio 2011b). Boekhoutia does not assimilate ethanol and D-mannitol, whereas all species of Kurtzmanomyces assimilate these two carbon sources.

description: This paper is a theoretical and a numerical investigation of the stability of a tip-cantilever system used in Non-Contact Atomic Force Microscopy (NC-AFM) when it oscillates close to a surface. No additional dissipative force is considered. The theoretical approach is based on a variationnal method exploiting a coarse grained operation that gives the temporal dependence of the nonlinear coupled equations of motion in amplitude and phase of the oscillator. Stability criterions for the resonance peak are deduced and predict a stable behavior of the oscillator in the vicinity of the resonance. The numerical approach is based on results obtained with a virtual NC-AFM developped in our group. The effect of the size of the stable domain in phase is investigated. These results are in particularly good agreement with the theoretical predictions. Also they show the influence of the phase shifter in the feedback loop and the way it can affect the damping signal.
A Two Stage Model of the Demand For Specialty Crop Insurance

description: Proposals for reform of the federal multiple-peril crop insurance program for specialty crops seek to change fees for catastrophic (CAT) insurance from a nominal fifty-dollar per contract registration fee to an actuarially sound premium. Growers argue that this would cause a significant reduction in participation rates, thus impeding the program's goals of eventually obviating the need for ad hoc disaster payments and worsening the actuarial soundness of the program. The key policy issue is, therefore, empirical one - whether the demand for specialty crop insurance is elastic or inelastic. Previous studies of this issue using either grower or county-level field crop data typically treat the participation problem as either a discrete insure / don't insure decision or aggregate these decisions to a continuous participation rate problem. However, a grower's problem is more realistically cast as one of simultaneously making a coverage level / insurance participation decision. Because the issue at hand considers a significant price increase for only one coverage level (50%), differentiating between these decisions is necessary both from an analytical and econometric standpoint. To model this decision, the paper develops a two-stage estimation procedure based on Lee's multinomial logit-OLS selection framework. This method is applied to a county-level panel data set consisting of eleven years of the eleven largest grape-growing counties in California. Results show that growers choose among coverage levels based upon expected net premiums and the variance of these returns, as well as the first two moments of expected market returns. At the participation-level, the mean and variance of indemnities are also important, as are several variables measuring the extent of self-insurance, such as farm size, enterprise diversity, or farm income. The results also show that the elasticity of 50% coverage insurance is elastic, suggesting that premium increases may indeed worsen the actuarial soundness of the program. These increases will also cause a significant adjustment of growers among coverage levels.

description: In observations of diffuse emissions like, e.g., the Lyman-$α$ heliospheric glow, contributions to the observed signal from point sources (e.g., stars) are considered as a contamination. There are relatively few brightest point sources that are usually properly resolved and can be subtracted or masked. We present results of analysis of the distribution of point sources using UV sky-survey maps from the SOHO/SWAN instrument and spectrophotometry data from the IUE satellite. The estimated distribution suggests that the number of these sources increases with decreasing intensity. Below a certain threshold, these sources cannot be resolved against the diffuse signal from the backscatter glow, that results in a certain physical background from unresolved point sources. Detection, understanding and subtraction of the point-source background has implications for proper characterization of diffuse emissions and accurate comparison with models. Stars are also often used as standard candles for in-flight calibration of satellite UV observations, thus proper understanding of signal contributions from the point sources is important for the calibration process. We present a general approach to quantify the background radiation level from unresolved point sources in UV sky-survey maps. In the proposed method, a distribution of point sources as a function of their intensity is properly integrated to compute the background signal level. These general considerations are applied to estimate the unresolved-point-sources background in the SOHO/SWAN observations that on average amounts to $28.9$ R. We discuss also the background radiation anisotropies and general questions related to modeling the point-source contributions to diffuse UV-emission observations.

description: At room temperature and under ambient conditions, due to the adsorption, a water film is always present on silica surfaces. If the surface is investigated with a scanning probe method in Contact mode, this causes the formation of a meniscus between the tip and the surface. This liquid neck generates additional capillary forces between the nano-tip and the surface. In dynamic mode, due to the action of the oscillating tip on the surface, the mechanical response of the adsorbed water layers can induce additional dissipation that is probed through the phase variations of the oscillator. In the present work, we analyze by dynamic force microscopy the growth of a water film on a silica surface as a function of time. The silica sample is first cleaned and heated at $420^\circ$C, then is exposed to dry conditions. The influence of the water film is checked with the dynamic mode by using intermittent contact and noncontact situations. To describe the experimental observations, additional dissipation is taken into account when the tip approaches the surface. The results of the fits allow the evaluation of the dissipation induced by the attractive interaction between the tip and the silica surface related to the adsorption of water molecules on surface as a function of time. Results are compared to previous tribological studies performed in Contact mode and infra-red spectroscopy measurements on the silica for which the key parameter was the surface temperature instead of time. The two experimental results are in good agreement.

We analyze the microscopic properties of small-large phase transition of black holes with pressure and volume as the fluctuation variables. We observe that strong repulsive interactions dominate among the micro-structures of near extremal small black holes, and the thermodynamic curvature diverges to positive infinity for the extremal black holes. At the critical point, however, thermodynamic curvature diverges to negative infinity.

description: This paper investigates the automatic exploration problem under the unknown environment, which is the key point of applying the robotic system to some social tasks. The solution to this problem via stacking decision rules is impossible to cover various environments and sensor properties. Learning based control methods are adaptive for these scenarios. However, these methods are damaged by low learning efficiency and awkward transferability from simulation to reality. In this paper, we construct a general exploration framework via decomposing the exploration process into the decision, planning, and mapping modules, which increases the modularity of the robotic system. Based on this framework, we propose a deep reinforcement learning based decision algorithm which uses a deep neural network to learning exploration strategy from the partial map. The results show that this proposed algorithm has better learning efficiency and adaptability for unknown environments. In addition, we conduct the experiments on the physical robot, and the results suggest that the learned policy can be well transfered from simulation to the real robot.
Equalizing filter design for cross-talk cancellation
Creators: name: Ren, Jihong
Publisher: name: University of British Columbia
Year: 2009

description: As interconnect line width and spacing decreases and operating clock rate increases, interconnect has become a bottleneck in developing high-speed integrated circuits, multichip modules, printed circuit boards, and systems. With small line spacing, mutual capacitance and inductance approach the level of self-capacitance and inductance, and can severely degrade signal integrity. The well-known equalizing filter method can significantly improve signal integrity. This thesis explores the effectiveness of equalizing niters in cross-talk cancellation for high-speed, off-chip buses. It demonstrates that linear programming provides effective methods for designing cross-talk canceling equalizing filters that greatly increase the bandwidth of high-speed digital buses.

description: We systematically investigate general forms of mass matrices for three-generation up and down quarks, including asymmetrical ones in generation space. Viable zero matrix elements are explored which are compatible with the current observation of masses and mixing angles, and also with the recent measurement of CP violation in the B-meson system. The simplest form with the maximal number of vanishing matrix elements is found to be almost consistent with the experimental data, but has a scratch that one of the mixing angle is slightly large. At the next-to-minimal level, it is found with a help of leptonic generation mixing that only six patterns of mass matrices well describe the experimental data. These sets of mass textures predict all the properties of quarks, including the CP violation, as well as the large (charged) lepton mixing, which may be appropriate for the atmospheric neutrino in grand unification scheme.

description: We study superdense relativistic stars with anisotropic matter distributions with spheroidal spatial hypersurfaces. We propose a methodology to make an anisotropic generalization of the Vaidya-Tikekar superdense star model. The anisotropic Einstein field equations can be solved in terms of hypergeometric functions for our choice of gravitational potential and anisotropy. Particular parameter choices allow us to generate models of anisotropic stars in terms of elementary functions. Also, isotropic stars can be generated in the limit of vanishing anisotropy. In particular, we obtain the well known superdense models of Tikekar which are isotropic and have specific spheroidal geometries. The impact of anisotropy on the gross physical behaviour of a compact star is studied.

description: We discuss the crossover between the small and large field cutoff (denoted x_{max}) limits of the perturbative coefficients for a simple integral and the anharmonic oscillator. We show that in the limit where the order k of the perturbative coefficient a_k(x_{max}) becomes large and for x_{max} in the crossover region, a_k(x_{max}) is proportional to the integral from -infinity to x_{max} of e^{-A(x-x_0(k))^2}dx. The constant A and the function x_0(k) are determined empirically and compared with exact (for the integral) and approximate (for the anharmonic oscillator) calculations. We discuss how this approach could be relevant for the question of interpolation between renormalization group fixed points.

description: We derive the analytical time delay of light propagating in the equatorial plane and parallel to the velocity of a moving Kerr-Newman black hole up to the second post-Minkowskian order via integrating the null geodesic equations. The velocity effects are expressed by a very compact form. We then concentrate on analyzing the magnitudes of the correctional effects on the second-order contributions to the delay and discuss their possible detection. Our result in the first post-Minkowskian approximation is in agreement with Kopeikin and Schäfer's formulation which is based on the retarded Liénard-Wiechert potential.

The initial valence quarks in put are taken from the GRV's next-to-leading order calculations on $F_2^p(x,Q^2)$ which give very good fit to the available data in the $(x,Q^2)$-plane. It is shown that the free neutron to proton structure functions ratio can be extracted from corresponding EMC ratios for $^3He$ and $^3H$ mirror nuclei by using self-consistent iteration procedure and the results are in good agreement with other theoretical models as well as present available experimental data, especially the one expected form the proposed 11 GeV Jefferson Laboratory.

description: We present a multiwavelength analysis of two homologous, short lived, impulsive flares of GOES class M1.4 and M7.3, that occurred from a very localized mini-sigmoid region within the active region NOAA 12673 on 2017 September 7. Both flares were associated with initial jet-like plasma ejection which for a brief amount of time moved toward east in a collimated manner before drastically changing direction toward southwest. Non-linear force-free field extrapolation reveals the presence of a compact double-decker flux rope configuration in the mini-sigmoid region prior to the flares. A set of open field lines originating near the active region which were most likely responsible for the anomalous dynamics of the erupted plasma, gave the earliest indication of an emerging coronal hole near the active region. The horizontal field distribution suggests a rapid decay of the field above the active region, implying high proneness of the flux rope system toward eruption. In view of the low coronal double-decker flux ropes and compact extreme ultra-violet (EUV) brightening beneath the filament along with associated photospheric magnetic field changes, our analysis supports the combination of initial tether-cutting reconnection and subsequent torus instability for driving the eruption.

Dependence of the photon statistics of down-converted field-modes on the photon statistics of pump field-mode

description: Using the zero time-delay second-order correlation function for studying the photon statistics, we investigate how the photon statistics of the field-modes generated by parametric down-conversion (PDC) process depends on the photon statistics of the pump field-mode. We derive general expressions for the zero time-delay second-order correlation function of the down-converted field-modes for both multi-mode and single-mode PDC processes. We further study these expressions in the weak down-conversion limit. We show that for a two-photon two-mode PDC process, in which a pump photon splits into two photons into two separate field-modes, the zero time-delay second-order correlation function of the individual down-converted field-modes is equal to twice that of the pump field-mode. Furthermore, for an $n$-photon $n$-mode down-conversion process, in which a pump photon splits into $n$ photons into $n$ separate field-modes, the zero time-delay second-order correlation function of the individual down-converted field-modes is equal to $2^{(n-1)}$ times that of the pump field-mode. However, in contrast to the multi-mode PDC processes, for a single-mode PDC process, in which a pump photons splits into two or more photons into a single mode, the zero time-delay second-order correlation function of the down-converted field-mode is not proportional to that of the pump in the weak down-conversion limit. Nevertheless, we find it to be inversely proportional to the average number of photons in the pump field-mode.

Probabilistic evidence combination for robust real time finger recognition and tracking
Creators: name: Jennings, Cullen Frishman
Publisher: name: University of British Columbia
Year: 2009

description: This thesis sets out a Bayesian approach to the robust combination of measurements from multiple sensors in different measurement spaces. Classical least squares optimization is used inside a sequential Monte Carlo approach to find the most likely local estimate. The local optimization speeds up the system, while the Monte Carlo approach improves robustness in finding the globally optimal solution. Models are simultaneously fit to all the sensor data. A statistical approach is taken to determine when inputs are failing and should be ignored. To demonstrate the overall approach described in this thesis, the 3D position and orientation of highly over-constrained models of deformable objects - fingers - are tracked. Accurate results are obtained by combining features of color and stereo range images. The multiple sources of information combined in this work include stereo range images, color segmentations, shape information and various constraints. The system is accurate and robust; it can continue to work even when one of the sources of information is completely failing. The system is practical in that it works in real time and can deal with complex moving backgrounds that have many edges, changing lighting, and other real world vision challenges.
Influence of noncontact dissipation in the tapping mode: Attempt to extract quantitative information on the surface properties with the local force probe method

description: In the Tapping mode, a variation of the oscillation amplitude and phase as a function of the tip sample distance is the necessary measurement to access quantitatively to the properties of the surface. In the present work, we give a systematic comparison between experimental data recorded on two surfaces, phase and amplitude, and theoretical curves. With an interaction between the tip and the surface taking into account an attractive and a repulsive term, the analytical approach is unable to properly describe the relationship between the phase variation and the oscillation amplitude variation. When an additional dissipation term is involved, due to the attractive interaction between the tip and the surface, the model gives a good agreement with the recorded data. Particularly, the trends in the phase variations related to the noncontact situations have been found to be amenable to an analysis based upon a simple viscoelastic behavior of the surface.

description: Spherically symmetric thin-shell wormholes are studied within the framework of Einstein-Born-Infeld theory. We analyze the exotic matter content and find that for certain values of the Born-Infeld parameter the amount of exotic matter on the shell can be reduced in relation to the Maxwell case. We also examine the mechanical stability of the wormhole configurations under radial perturbations preserving the spherical symmetry.

Re-envisioning Nottingham Way: a comprehensive response to East Trenton's post-industrial landscape
Creators: name: Cincotta, Jason
Publisher: name: No Publisher Supplied
Year: 2021

description: Urban, post-industrial landscapes across the United States are in desperate need of reimagining. The existence of hundreds of thousands of brownfields around the country, many abandoned and dilapidated, presents an opportunity for repurposing parts of our most culturally significant cities for exciting new uses. This thesis looks at how landscape design could be used to re-envision a brownfield site in Trenton, New Jersey. The design site, part of a larger, 100-acre greenway proposal known as Nottingham Way, is a 12-acre property which lies at the intersection where today’s East Trenton neighborhood was first conceived. The final product, Nottingham Way Ecological and Arts Center Park, is the product of a comprehensive design process which examined research and data through five criteria lenses. Once collected, the information was layered together and critically analyzed to highlight useful patterns and relationships. After the narrative of site and neighborhood was clear, design solutions to the site’s various challenges were developed. The result is a model for remediated and revitalized landscape transitioned into a public space. Designed as a local and regional park, it also serves as an ecological sanctuary and artist hub, with opportunities for passive recreation and trail connections to the surrounding greenway systems.

description: We estimate the star-formation rates and the stellar masses of the Extremely Red objects (EROs) detected in a 180arcmin2 Ks-band survey (Ks~20mag). This sample is complemented by sensitive 1.4GHz radio observations (12micro-Jy; 1sigma rms) and multiwaveband photometric data (UBVRIJ) as part of the Phoenix Deep Survey. For bright K<19.5mag EROs in this sample (I-K>4mag; total of 177) we use photometric methods to discriminate dust-enshrouded active systems from early-type galaxies and to constrain their redshifts. Radio stacking is then employed to estimate mean radio flux densities of 8.6 (3sigma) and 6.4micro-Jy (2.4sigma) for the dusty and early-type subsamples respectively. Assuming that dust enshrouded active EROs are powered by star-formation the above radio flux density at the median redshift of z=1 translates to a radio luminosity of 4.5e22W/Hz and a star-formation rate of SFR=25Mo/yr. Combining this result with photometric redshift estimates we find a lower limit to the star-formation rate density of ~0.02Mo/yr/Mpc^3 for the K<19.5mag dusty EROs in the range z=0.85-1.35. Comparison with the SFR density estimated from previous ERO samples (with similar selection criteria) using optical emission lines, suffering dust attenuation, suggests a mean dust reddening of at least E(B-V)~0.5 for this population. We further use the Ks-band luminosity as proxy to stellar mass and argue that the dust enshrouded EROs in our sample are massive systems, M>5e10Mo. We also find that EROs represent a sizable fraction (~50%) of the number density of galaxies more massive than M=5e10Mo at z~1, with almost equal contributions from dusty and early types. Similarly, we find that EROs contribute about half of the mass density of the Universe at z~1 after taking into account incompleteness because of the limit K=19.5mag.

description: To date, the process of conversion to organic farming has been analysed as a choice between only two alternatives, conventional versus organic farming. However, the conversion process in the EU is a two-tier decision, which brings the possibility of a nested structure between mixed and organic farming. In the context of Sweden, where the conversion investment is flexible, we attempted to identify economic determinants of the organic conversion process. For that purpose, we applied the nested Logit random utility maximisation (NLRUM) model to data from the Swedish farm accounting data network for 2002-2012. The analysis showed that milk prices, milk yield and environmental support payments play a significant role in the organic conversion process. As expected, a decrease in conventional milk prices would induce conventional farms to convert to organic production. The scale of conversion to organic farming was more pronounced among dairy farms located in regions with higher environmental support payments, and in regions endowed with more pasture land and leys.

description: In this paper, we propose a way to realize topological $s$-wave superconductivity with application of circularly polarized laser light in two-dimensional bilayer transition metal dichalcogenides (TMDs). Using Floquet theory, we analyze a tight-binding model of bilayer TMDs with time-periodic electric fields. After deriving an effective Hamiltonian, we investigate topological properties of the $s$-wave superconducting state. The laser light induces valley-dependent layer polarization and makes the system to be a topologically nontrivial superconducting state characterized by the Chern number. We show topological phase diagrams in the absence and presence of the Kane-Mele spin-orbit coupling which causes hidden spin polarization in bilayer TMDs. Although the topological phase diagram is affected by the spin-orbit coupling, topological superconductivity can be realized without relying on the spin-orbit coupling in sharp contrast to a previous proposal of laser-induced topological superconductivity [K. Takasan, \textit{et al.}, Phys. Rev. B \textbf{95}, 134508 (2017)]. We also discuss experimental setups to detect the topological phase.

description: The Harper map is one of the simplest chaotic systems exhibiting reconnection of invariant manifolds. The method of asymptotics beyond all orders (ABAO) is used to construct stable/unstable manifolds of the Harper map. When the parameter changes to the reconnection threshold, the stable/unstable manifolds are shown to acquire new oscillatory portion corresponding to the heteroclinic tangle after the reconnection.

description: Dirac's quantization condition, $eg=n/2$ ($n \in \Bbb Z$), and Schwinger's quantization condition, $eg=n$ ($n \in \Bbb Z$), for an electric charge $e$ and a magnetic charge $g$ are derived by utilizing the Atiyah-Singer index theorem in two dimensions. The massless Dirac equation on a sphere with a magnetic-monopole background is solved in order to count the number of zero-modes of the Dirac operator.
