description: We show how sign problems in simulations of many-body systems can manifest themselves in the form of heavy-tailed correlator distributions, similar to what is seen in electron propagation through disordered media. We propose an alternative statistical approach for extracting ground state energies in such systems, illustrating the method with a toy model and with lattice data for unitary fermions and for baryons in QCD.

description: As a concern with the reliability, bandwidth and mass of future optical links in LHC experiments, we are investigating CW lasers and light modulators as an alternative to VCSELs. These links will be particularly useful if they utilize light modulators which are very small, low power, high bandwidth, and are very radiation hard. We have constructed a test system with 3 such links, each operating at 10 Gb/s. We present the quality of these links (jitter, rise and fall time, BER) and eye mask margins (10GbE) for 3 different types of modulators: LiNbO3-based, InP-based, and Si-based. We present the results of radiation hardness measurements with up to ~1012 protons/cm2 and ~65 krad total ionizing dose (TID), confirming no single event effects (SEE) at 10 Gb/s with either of the 3 types of modulators. These optical links will be an integral part of intelligent tracking systems at various scales from coupled sensors through intra-module and off detector communication. We have used a Si-based photonic transceiver to build a complete 40 Gb/s bi-directional link (10 Gb/s in each of four fibers) for a 100m run and have characterized it to compare with standard VCSEL-based optical links. Some future developments of optical modulator-based high bandwidth optical readout systems, and applications based on both fiber and free space data links, such as local triggering and data readout and trigger-clock distribution, are also discussed.

description: PBS&J, on behalf of Dial Cordy and Associates, Inc. and the Canal Port Authority of Port Canaveral, conducted a reconnaissance-level cultural resources assessment of lands adjacent to the Canaveral Barge Canal on March 30 and 31, 2006. The Canal Port Authority plans to dredge the canal and to make other safety and navigation improvements. The Canal Port Authority proposes to enlarge the Canaveral Barge Canal to a width of 500 feet in selected locations, and to remove land composed of dredge spoil to expand the West Turning Basin. It is the opinion of PBS&J, that dredging of the canal as currently proposed will not impact any significant cultural resources on the subject tracts included in this assessment, and that the project will have no adverse effect on archaeological or historical properties listed or eligible for listing in the National Register of Historic Places, or otherwise of historical or archaeological value.

description: Understanding the genetic basis of adaptive traits is one of the central goals of modern plant biology. Deciphering how phenotype maps to the genotype is a complex problem that requires answering multiple questions: Is the phenotype environmentally induced, or is it genetically controlled? What gene(s) underlie the phenotype? Are the gene(s) associated with other phenotypes which might impact its evolutionary potential? These questions can be answered using a combination of quantitative and population genetic approaches. In this thesis, I apply these approaches to two complex adaptive phenotypes -- leaf shape in Ipomoea batatas (sweetpotato) and herbicide resistance in Ipomoea purpurea (common morning glory) -- to identify putative genes and mechanisms contributing to phenotype. Further, I synthesize a framework for analyzing genetic correlations that underlie most complex traits. I show that leaf shape variation is extensive and largely under genetic control in sweetpotato, and likewise, identify genes putatively associated with leaf shape variation. I also show that although simple leaf shape descriptors are not environmentally controlled when considered together these can be influenced to a great extent by the environment. Next, using genome-wide resequencing, RNA-Seq and functional tests I show that the detoxification mechanism underlies the polygenic herbicide resistance in the common morning glory. Using linkage analysis, I identify a role of intrerchromosomal linkage disequilibrium in maintaining the resistance alleles over generations. Moreover, I identify loci associated with the cost of resistance and show the potential role of genetic-hitchhiking in maintaining the cost. Lastly, I review the current methods available for studying the genetic basis of trait correlations, and highlight the pitfalls associated with such methods. I thus synthesize an analytical framework which can more precisely identify the genes and mechanisms underlying trait correlations. Together, my thesis identifies the genetic basis of adaptive phenotypes in the genus Ipomoea and thus narrows the gap between genotype and adaptive phenotypes.

description: We investigate the dynamics of two bosons trapped in an infinite one-dimensional optical lattice potential within the framework of the Bose-Hubbard model and derive an exact expression for the wavefunction at finite time. As initial condition we chose localized atoms that are separated by a distance of $d$ lattice sites and carry a center of mass quasi-momentum. An initially localized pair ($d=0$) is found to be more stable as quantified by the pair probability (probability to find two atoms at the same lattice site) when the interaction and/or the center of mass quasi-momentum is increased. For initially separated atoms ($d \neq 0$) there exists an optimal interaction strength for pair formation. Simple expressions for the wavefunction, the pair probability and the optimal interaction strength for pair formation are computed in the limit of infinite time. Whereas the time-dependent wavefunction differs for values of the interaction strength that differ only by the sign, important observables like the density and the pair probability do not. With a symmetry analysis this behavior is shown to extend to the $N$-particle level and to fermionic systems. Our results provide a complementary understanding of the recently observed [Winkler \textit{et al.}, Nature (London) \textbf{441}, 853 (2006)] dynamical stability of atom pairs in a repulsively interacting lattice gas.

description: Point-contact Andreev reflection spectroscopy is used to measure the spin polarization of metals but analysis of the spectra has encountered a number of serious challenges, one of which is the difficulty to distinguish the effects of spin polarization from those of the finite lifetime of Cooper pairs. We have recently confirmed the polarization-lifetime ambiguity for Nb-Co and Nb-Cu contacts and suggested to use Fermi surface mismatch, the normal reflection due to the difference of Fermi wave vectors of the two electrodes, to solve this dilemma. Here we present further experiments on contacts between superconducting Nb and the ferromagnets Fe and Ni as well as the noble metals Ag and Pt that support our previous results. Our data indicate that the Nb - normal metal interfaces have a transparency of up to about 80 per cent and a small, if not negligible, spin polarization.

description: On May 6, 2014, the US Army Corps of Engineers, Jacksonville District conducted a submerged cultural resources remote sensing survey of the North Reach Nearshore Disposal and Sand Rehandling Area (NDSRA) extension offshore of Brevard County, Florida, on submerged state lands. This survey was conducted to identify the presence or absence of submerged cultural resources within the NDSRA extension area and is an addendum to the initial survey by Watts (2000). The submerged cultural resources remote sensing survey of the NDSRA extension area utilized a magnetometer, side scan sonar, and sub-bottom profiler, integrated with a Differential Global Positioning System (DGPS) to identify any potentially significant submerged cultural resources within the proposed borrow area. Results of the remote sensing survey identified no potentially significant submerged cultural resources within the North Reach NDSRA extension. The North Reach NDSRA extension is cleared from an archaeological perspective and no additional work is recommended for this area. This is a draft report.
Slicing the Torus: Obscuring Structures in Quasars

description: Quasars and Active Galactic Nuclei (AGNs) are often obscured by dust and gas. It is normally assumed that the obscuration occurs in an oblate "obscuring torus", that begins at the radius at which the most refractive dust can remain solid. The most famous form of this torus is a donut-shaped region of molecular gas with a large scale-height. While this model is elegant and accounts for many phenomena at once, it does not hold up to detailed tests. Instead the obscuration in AGNs must occur on a wide range of scales and be due to a minimum of three physically distinct absorbers. Slicing the "torus" into these three regions will allow interesting physics of the AGN to be extracted.

Process simulation, economic analysis and synthesis of biodiesel from waste vegetable oil using supercritical methanol
Creators: name: Lee, Soo Jin
Publisher: name: University of British Columbia
Year: 2010

description: Biodiesel production using supercritical methanol received attention as an alternative method to replace the conventional alkali-catalyzed method being practiced in industry. Due to its flexibility to feedstock compared to the conventional method, the supercritical method for waste vegetable oil conversion appears to be promising in environmental and economical points of views. Four industrial-scale biodiesel production processes were simulated using Hysys. Each process used either the conventional or the supercritical method. The first model simulated the alkali-catalyzed process using fresh vegetable oil. The second process model resembled the first one as it uses sodium hydroxide catalyst in transesterification, but pre-treatment process of waste vegetable oil was included. The third and fourth models were supercritical biodiesel production processes using waste vegetable oil. Fourth model had differences from the third one in terms of the amount of methanol being introduced to a plug flow reactor and the way of recovering methanol from reaction products, both of which can reduce energy consumption of the process. To improve the accuracy of the process simulations, properties of a model compound (triolein) of the vegetable oils were examined via thermogravimetric analysis, and the experimental data were incorporated into the simulation models. Economical aspects of the developed simulation models were then assessed using Aspen Icarus Process Evaluator. The economic assessment revealed that supercritical processes using waste vegetable oil were competitive to the conventional process based on their better profitability indicators such as discounted payback period and net present value. The net present value prediction formulas were derived for the four processes via statistical analysis of the vegetable oil price, biodiesel selling price, by-product selling price and interest rate that were found to most strongly affect the profitability of the biodiesel production processes by sensitive analysis. Experiments of biodiesel synthesis from waste canola oil were conducted using supercritical methanol. High methyl ester yields over 96% were achieved after 45 min of reaction time at 270°C/10 MPa with methanol to oil ratios of 1:1 and 2:1. Side reactions such as glycerol decomposition and glycerol methanolysis were confirmed by water content measurement using Karl-Fischer titration and Gas chromatography-mass spectrometry (GC-MS) analysis.

description: The standard model of particle physics is known to be incomplete due to the lack of a dark matter candidate, an explanation for the hierarchy problem, a mechanism for the generation of the baryon asymmetry, and a resolution to the strong CP problem. In this thesis, we examine possible solutions to these issues via extensions of the standard model, with a focus on the particle nature of dark matter. We detail many possible experimental probes of these proposed models, including the projected sensitivity of an upcoming telescope, and the effect of massive dark matter impacts on red-giant stellar cores. First, we propose a hidden sector extension of the minimal supersymmetric standard model that interacts with visible matter through supersymmetric kinetic mixing. This provides a natural description for weak scale dark matter whilst preserving the supersymmetric solution to the hierarchy problem. We investigate multiple probes of this dark matter through existing collider and direct detection searches, and the upcoming Cherenkov Telescope Array. We focus on the effects of R-parity violating decays of neutralinos on the dark matter cosmology and photon spectrum. The extremely low event rate of macroscopic dark matter in traditional dark matter searches warrants a look at new constraints. We show that the degenerate cores of red giant stars serve as potential detectors of macroscopic dark matter through the trigger of a core-wide ignition event, the helium flash. Data from a large population of red giant stars in the M15 globular cluster gives a novel constraint on heavy macroscopic dark matter. Lastly, we consider a model for very light dark matter, the axion, in a supersymmetric setting. We show that the rotation of the axion field can be successfully transferred, via strong sphalerons and R-parity violating interactions, to the measured baryon asymmetry of the universe. Focusing on a coupling texture motivated by grand unified theory, we can successfully recover the measured baryon asymmetry and dark matter abundance, while maintaining the axion solution to the strong CP problem. The viable region of parameter space can be probed by proton decay measurements, collider and long-lived particle searches, axion searches, and gravitational waves.

description: Background: Long-term prescriptions of strong opioids for chronic noncancer pain-which are not supported by scientific evidence-suggest miscalibrated risk perceptions among those who prescribe, dispense, and take opioids. Because risk perceptions and behaviors can differ depending on whether people learn about risks through description or experience, we investigated the effects of descriptive versus simulated-experience educative formats on physicians' risk perceptions of strong opioids and their prescription behavior for managing chronic noncancer pain. Methods: Three hundred general practitioners and 300 pain specialists in Germany-enrolled separately in two independent exploratory randomized controlled online trials-were randomly assigned to either a descriptive format (fact box) or a simulated-experience format (interactive simulation). Primary endpoints: Objective risk perception (numerical estimates of opioids' benefits and harms), actual prescriptions of seven therapy options for managing chronic pain. Secondary endpoint: Implementation of intended prescriptions of seven therapy options for managing chronic pain. Results: Both formats improved the proportion of correct numerical estimates of strong opioids' benefits and harms immediately after intervention, with no notable differences between formats. Compared to description, simulated experience led to significantly lower reported actual prescription rates for strong and/or weak opioids, and was more effective at increasing prescription rates for non-drug-based therapies (e.g., means of opioid reduction) from baseline to follow-up for both general practitioners and pain specialists. Simulated experience also resulted in a higher implementation of intended behavior for some drug-based and non-drug-based therapies. Conclusions: The two formats, which recruit different cognitive processes, may serve different risk-communication goals: If the goal is to improve exact risk perception, descriptive and simulated-experience formats are likely to be equally suitable. If, however, the goal is to boost less risky prescription habits, simulated experience may be the better choice.

description: We propose an effective action for a p'-brane with open p-branes ending on it. The action has dual descriptions similar to the commutative and non-commutative ones of the DBI action for D-branes and open strings. The Poisson structure governing the non-commutativity of the D-brane is replaced by a Nambu structure and the open-closed string relations are generalized to the case of p'-branes utilizing a novel Nambu sigma model description of p-branes. In the case of an M5-brane our action interpolates between M5-actions already proposed in the literature and matrix model like actions involving Nambu structures.

description: In the present study we report on properties of ZnCoO films grown at relatively low temperature by the Atomic Layer Deposition, using two reactive organic zinc precursors (dimethylzinc and diethylzinc). The use of these precursors allowed us the significant reduction of a growth temperature to below 300oC. The influence of growth conditions on the Co distribution in ZnCoO films, their structure and magnetic properties was investigated using Secondary Ion Mass Spectroscopy, Scanning Electron Microscopy, Cathodoluminescence, Energy Dispersive X-ray Spectrometry (EDX), X-ray diffraction and Superconducting Quantum Interference Device magnetometry. We achieved high uniformity of the films grown at 160°C. Such films are paramagnetic. Films grown at 200° and at higher temperature are nonuniform. Formation of foreign phases in such films was detected using high resolution EDX method. These samples are not purely paramagnetic and show weak ferromagnetic response at low temperature.

description: The European Food Safety Authority (EFSA) identified extended-spectrum β-lactamase/AmpC β-lactamase (ESBL/AmpC)-producing E. coli as one of the main priority hazards for poultry. Different studies detected ESBL-producing E. coli at broiler fattening farms and in abattoirs, concluding that poultry meat is a potential source of human infection. Broiler breast skin samples taken in three abattoirs with different scalding techniques were examined for ESBL-producing Escherichia (E.) coli and their phylogenetic groups. A total of 307 ESBL-producing E. coli isolates were found, and the abattoir with conventional immersion scalding with thermal treatment of the water had the lowest incidence. Phylogroups D/E and B1 were mostly detected, while phylogroups C, D, and E were not detected. Phylogroup B2 was detected in low proportions. The phylogroups B2 and D are important as they have been associated with urinary tract infections in humans, but were only detected in low proportions at different processing stages in this study. Since the risk for the consumer of being infected via chicken meat with ESBL-producing E. coli and E. coli of highly pathogenic phylogroups cannot be excluded, good kitchen hygiene is of great importance.

description: We present and discuss the mean rest-frame ultraviolet spectrum for a sample of 81 Lyman Break Galaxies (LBGs) selected to be B-band dropouts with a mean redshift of z=3.9 and apparent magnitudes z_AB<26. Most of the individual spectra are drawn from our ongoing survey in the GOODS fields with the Keck DEIMOS spectrograph, and we have augmented our sample with published data taken with FORS2 on the VLT. In general we find similar trends in the spectral diagnostics to those found in the earlier, more extensive survey of LBGs at z=3 undertaken by Shapley et al (2003). Specifically, we find low-ionization absorption lines which trace the presence of neutral outflowing gas are weaker in galaxies with stronger Lyman-alpha emission, bluer UV spectral slopes, lower stellar masses, lower UV luminosities and smaller half-light radii. This is consistent with a physical picture whereby star formation drives outflows of neutral gas which scatters Lyman-alpha and gives rise to strong low-ionization absorption lines, while increasing the stellar mass, size, metallicity, and dust content of galaxies. Typical galaxies are thus expected to have stronger Lyman-alpha emission and weaker low-ionization absorption at earlier times (higher redshifts). Indeed, our mean spectrum at z=4 shows somewhat weaker low-ionization absorption lines than at z=3 and available data at higher redshift indicates a rapid decrease in low-ionization absorption strength with redshift. We argue that the reduced low-ionization absorption is likely caused by a decrease in the covering fraction and/or velocity range of outflowing neutral gas at earlier epochs. Our continuing survey will enable us to extend these diagnostics more reliably to higher redshift and determine the implications for the escape fraction of ionizing photons which governs the role of early galaxies in cosmic reionization.

description: Background: Acquiring medical knowledge is a key competency for medical students and a lifelong requirement for physicians. Learning techniques can improve academic success and help students cope with stressors. To support students' learning process medical faculties should know about learning techniques. The purpose of this study is to analyse the preferred learning techniques of female and male as well as junior and senior medical students and how these learning techniques are related to perceived learning difficulties. Methods: In 2019, we conducted an online survey with students of the undergraduate, competency-based curriculum of medicine at Charite - Universitatsmedizin Berlin. We chose ten learning techniques of high, moderate and low utility according to Dunlosky et al. (2013) and we asked medical students to rate their preferred usage of those techniques using a 5-point Likert scale. We applied t-tests to show differences in usage between female and male as well as junior and senior learners. Additionally, we conducted a multiple regression analysis to explore the predictive power of learning techniques regarding perceived difficulties. Results: A total of 730 medical students (488 women, 242 men, M-age = 24.85, SD = 4.49) use three techniques the most: 'highlighting' (low utility), 'self-explanation' (moderate utility) and 'practice testing' (high utility). Female students showed a significantly higher usage of low-utility learning techniques (t(404.24) = -7.13, p < .001) and a higher usage of high-utility learning techniques (t(728) = -2.50, p < .05) than male students (M = 3.55, SD = .95). Compared to junior students (second to sixth semester; M = 3.65, SD = .71), senior students (seventh semester to final clerkship year; M = 3.52, SD = .73) showed a lower use of low-utility learning techniques (t(603) = 2.15, p < .05). Usage of low-utility techniques is related to more difficulties (beta = .08, t(724) = 2.13, p < .05). Usage of moderate-utility techniques is related to less learning difficulties (beta = -.13, t(599) = -3.21, p < .01). Conclusions: Students use a wide range of low-, moderate- and high-utility learning techniques. The use of learning techniques has an influence on the difficulties perceived by students. Therefore, they could benefit from knowing about and using high-utility learning techniques to facilitate their learning. Faculties should inform their students about effective learning and introduce them to useful learning techniques.

description: This archaeological reconnaissance was undertaken by Florida Technological University personnel at the request of NASA for purposes of determining whether or not prehistoric or historic cultural remains occur in the area of the proposed Solid Rocket Booster Facility site, to be located not far south of the present VAB structure on Merritt Island. The survey resulted in locating only one historical site marked by remnants of a brick chimney and scattered domestic artifacts. No further evidence of either prehistoric or historical significance was recovered.

description: Quantum dots are artificial atoms used for a multitude of purposes. Charge defects are commonly present and can significantly perturb the designed energy spectrum and purpose of the dots. Voltage controlled exchange energy in silicon double quantum dots (DQD) represents a system that is very sensitive to charge position and is of interest for quantum computing. We calculate the energy spectrum of the silicon double quantum dot system using a full configuration interaction that uses tight binding single particle wavefunctions. This approach allows us to analyze atomic scale charge perturbations of the DQD while accounting for the details of the complex momentum space physics of silicon (i.e., valley and valley-orbit physics). We analyze how the energy levels and exchange curves for a DQD are affected by nearby charge defects at various positions relative to the dot, which are consistent with defects expected in the metal-oxide-semiconductor system.

description: Pollarding oak trees is a traditional silvopastoral technique practiced across wide areas of the northern Zagros mountains, a unique and vast semi-arid forest area with a strong cultural and ecological significance. So far, the effects of pollarding on tree structure in terms of DBH (diameter at breast height)~H (height) relationships within the typical pollarding cycle, which often lasts 4 years, has not been scientifically described. Here, we combine field inventories of DBH with H obtained from photogrammetric UAV flights for the first time to assess DBH~H relationships within this system. We conducted the research at six pollarded forest sites throughout the Northern Zagros. The sampling encompassed all three main species of coppice oak trees. In the case of multi-stem trees, we used the maximum DBH of each tree that formed a unique crown. A linear relationship between UAV and extracted H and the maximum DBH of pollarded trees explained a notable part of the variation in maximum DBH (R2 = 0.56), and more complex and well-known nonlinear allometries were also evaluated, for which the accuracies were in the same range as the linear model. This relationship proved to be stable across oak species, and the pollarding stage had a notable effect on the DBH~H relationship. This finding is relevant for future attempts to inventory biomass using remote sensing approaches across larger areas in northern Zagros, as well as for general DBH estimations within stands dominated by pollarded, multi-stem coppice structures.

description: Background: Entrustable professional activities (EPAs) have been defined to promote the workplace participation of undergraduate medical students, generally in the context of high-income countries with a focus on the secondary and tertiary health care sectors. These EPAs have limited applicability to training and health care contexts in low- to middle-income countries that have a focus on primary health care, for instance, the context of community medicine. The purpose of this article is to report the process and results of defining EPAs for undergraduate medical training in a community health care setting. Methods: A modified Delphi study was performed to develop EPAs for the training of medical students in community medicine during their first and second years of education at the Marilia Medical School (FAMEMA), Brazil. The supervision level was operationalized in terms of a student's ability to perform the EPA autonomously in an effective and safe manner with supervision readily available on request. Panellists (9 physicians and 6 nurses) rated the completeness of the proposed list of EPAs and EPA categories on four-point Likert scales. The threshold for consensus among panellists was a mean content validity index of at least 80%. Results: Consensus was reached after two Delphi rounds, resulting in 11 EPAs for undergraduate medical education and training in community medicine. These EPAs were organized into three overarching EPA domains: integrality of care for individual health needs in all phases of the life cycle (5 EPAs), integrality of care for family health needs (3 EPAs), and integrality of care for community health needs (3 EPAs). For each EPA, descriptions of the following categories were created: title; specifications and limitations; conditions and implications of the entrustment decision; knowledge, skills, and attitudes; links to competencies; and assessment sources. Conclusion: The resulting 11 EPAs for training medical students in community medicine expand the application of the EPA framework to both early undergraduate medical education and the context of primary health care. This report can support and guide other medical schools in their attempts to train students in primary health care contexts and to incorporate EPAs into their curricula.

description: Air quality and climate change are among the biggest societal challenges that we face today.
 Atmospheric free radicals, particularly hydroxyl (•OH) and nitrate (•NO3), are the drivers of chemical processes that determine atmospheric composition and thus influence local and global air quality and climate. Detecting and understanding the behavior of radical species in the atmosphere is therefore of paramount importance and hence a major research goal in atmospheric science. Current techniques for measuring radicals are based on spectroscopic and mass spectrometric methods, which although sensitive and robust, are technically complex, cumbersome, and expensive. The central aim of this project is to develop organic surfaces on confined 1D interfaces to fabricate radical sensors on a Silicon junctionless nanowire transistor (Si JNT) platform. Silicon junctionless nanowire transistors (JNTs) have recently detected record low concentrations (down to the zeptomolar range) of the protein streptavidin in liquid phase. However, JNTs have not yet been tested for sensing in gas phase. Smartcom Synapse being used in the device are a modular logging device for IoT data acquisition and processing.
