The demand to develop Materials Genomics and Integrated Materials Computation requires the availability of high temperature property data of liquid metals. As computing power and algorithms are constantly being improved, the accuracy of thermophysical property data has emerged as one of the limiting factors. Knowledge of these properties for materials such as Al and Al-alloys is a critical factor in numerical simulations and modelling of a wide array of industrial processes. This work reports on the measurement of viscosity, surface tension and density of liquid Al and Al-22.5wt.%Cu using the Discharge Crucible method. By comparing to other experimental data published in literature, as well as several theoretical and empirical models, the results from this study have achieved, with a varying degree of success, the goal of validating the Discharge Crucible method as a viable, cost-effective measurement method. However, while viscosity and surface tension proved to be in good agreement with other published data and model calculations, density were found to be significantly lower than expected. Through analysis, it was determined that wetting of Al or Al-Cu at the orifice of the Al2O3 crucible has an effect on flow rate since modelling of the flow using the modified-Bernoulli formulation does not account for accelerative losses within the meniscus. Dimensionless number analysis identified that wetting had an immediate effect on the flow rate, becoming more dominant with decreasing Capillary number, and hence drain time. In looking at the sensitivity of the Discharge Crucible model, it was determined that density had the largest effect on flow rate, thus explaining the link between the role of orifice wetting and the inaccurate density measurements (as opposed to viscosity or surface tension). Future research will aim to extend the Discharge Crucible model and method to account for wetting at the orifice, particularly at high temperatures.

description: Superluminous supernovae radiate up to 100 times more energy than normal supernovae. The origin of this energy and the nature of their stellar progenitors are poorly understood. We identify neutral iron lines in the spectrum of one such transient, SN 2006gy, and show that they require a large mass of iron (>~0.3 Msun) expanding at 1500 km/s. We demonstrate that a model of a standard Type Ia supernova hitting a shell of circumstellar material produces a light curve and late-time iron-dominated spectrum that match SN 2006gy. In such a scenario, common envelope evolution of the progenitor system can synchronize envelope ejection and supernova explosion and may explain these bright transients.

description: Remote Sensing (RS) image classification has recently attracted great attention for its application in different tasks, including environmental monitoring, battlefield surveillance, and geospatial object detection. The best practices for these tasks often involve transfer learning from pre-trained Convolutional Neural Networks (CNNs). A common approach in the literature is employing CNNs for feature extraction, and subsequently train classifiers exploiting such features. In this paper, we propose the adoption of transfer learning by fine-tuning pre-trained CNNs for end-to-end aerial image classification. Our approach performs feature extraction from the fine-tuned neural networks and remote sensing image classification with a Support Vector Machine (SVM) model with linear and Radial Basis Function (RBF) kernels. To tune the learning rate hyperparameter, we employ a linear decay learning rate scheduler as well as cyclical learning rates. Moreover, in order to mitigate the overfitting problem of pre-trained models, we apply label smoothing regularization. For the fine-tuning and feature extraction process, we adopt the Inception-v3 and Xception inception-based CNNs, as well the residual-based networks ResNet50 and DenseNet121. We present extensive experiments on two real-world remote sensing image datasets: AID and NWPU-RESISC45. The results show that the proposed method exhibits classification accuracy of up to 98%, outperforming other state-of-the-art methods.

description: Organic chemistry in the nineteenth century developed with a specific order of discovery, which was the inevitable path by which our knowledge of organic chemistry had to develop. New methods of analysis of organic materials led to new experimental results, which led to new theories about the nature of organic chemistry. Some of those theories were eventually abandoned, but additional experimental results soon resulted in new theories relating to the valency of carbon atoms and the ability of carbon atoms to combine together to form chains of carbon atoms. Even theories which were later abandoned, due to being contradicted by later experimental results, were logical explanations of knowledge acquired by earlier experimental results. Due to this even incorrect theories can be said to have arisen logically from information available at a particular point in time and to have been an inevitable part of the growth in our knowledge of organic chemistry.
On the energetic origin of self-limiting trenches formed around Ge/Si quantum dots

description: At high growth temperatures, the misfit strain at the boundary of Ge quantum dots on Si(001) is relieved by formation of trenches around the base of the islands. The depth of the trenches has been observed to saturate at a level that depends on the base-width of the islands. Using finite element simulations, we show that the self-limiting nature of trench depth is due to a competition between the elastic relaxation energy gained by the formation of the trench and the surface energy cost for creating the trench. Our simulations predict a linear increase of the trench depth with the island radius, in quantitative agreement with the experimental observations of Drucker and coworkers.

description: Gulf War Illness (GWI) is a multisymptom disorder including widespread chronic pain, fatigue and gastrointestinal problems. The objective of this study was to examine the low glutamate diet as a treatment for GWI. Forty veterans with GWI were recruited from across the US. Outcomes included symptom score, myalgic score, tender point count, dolorimetry and the Chalder Fatigue Scale. Subjects were randomized to the low glutamate diet or a wait-listed control group, with symptom score being compared after one month. Subjects then went onto a double-blind, placebo-controlled crossover challenge with monosodium glutamate (MSG)/placebo to test for return of symptoms. Symptom score was compared between diet intervention and wait-listed controls with an independent t-test and effect size was calculated with Cohen’s d. Change scores were analyzed with Wilcoxon Signed Rank tests. Crossover challenge results were analyzed with General Linear Models and cluster analysis. The diet intervention group reported significantly less symptoms (p = 0.0009) than wait-listed controls, with a very large effect size, d = 1.16. Significant improvements in average dolorimetry (p = 0.0006), symptom score, tender point number, myalgic score and the Chalder Fatigue Scale (all p < 0.0001) were observed after the 1-month diet. Challenge with MSG/placebo resulted in significant variability in individual response. These results suggest that the low glutamate diet can effectively reduce overall symptoms, pain and fatigue in GWI, but differential results upon challenge suggest that other aspects of the diet, or underlying differences within the population, may be driving these changes. Future research is needed to identify potential nutrient effects, biomarkers, and underlying metabolic differences between responders and non-responders.

description: The lowest order radiative correction to the differential cross-section of process of muon pair production with emission of hard photon at high energy electron-positron annihilation are calculated. Taking into account the emission of additional soft and hard photon the cross-section can be put in the form of Drell-Yan process in leading logarithmical approximation. Applying the crossing transformation we obtain the cross section of radiative electron-muon high-energy scattering process. Virtual and soft photon emission contributions of non-leading form are tabulated for several typical kinematical points. The limit of small invariant mass of muon pair is in agreement with our previous analysis.

description: Purpose: Maintaining a healthy eating pattern plays a key role in ensuring optimal health outcomes, yet, in areas considered food desertsand lower-income neighborhoods where the accessibility of healthy foods and beverages is limited, the pursuit of adequate nutrient intake is rendered cumbersome. This pilot program aims to improve access to healthful foods by supporting corner stores in stocking and promoting the purchase of produce. Methods: DC Central Kitchen's Healthy Corners program in Washington, DC piloted a nutrition incentive model in 17 corner stores that were upgraded to stock an increased variety and quantity of fresh produce. This program, entitled 5-for-5,provided a $5 coupon toward the purchase of fresh produce to Supplemental Nutrition Assistance Program (SNAP) shoppers making a qualifying purchase of $5 or more with SNAP benefits. Results: Evaluation based on store owner buy-in and customer intercept surveys indicated overall satisfaction in program offerings with 77% of SNAP shoppers polled indicating an increase in produce consumption as a direct result of the program. Coupon distribution data indicated that in the 5-for-5 program's first year, 76.5% of all 57,989 distributed coupons were redeemed, amounting to $221,770 worth of incentivized fresh produce sales. Conclusion: The results of the incentive program were promising with increases in the amount of produce purchased as a result of the program. Lessons learned concerning the use of a financial incentive to encourage the purchase of produce at corner stores is explored, as well as the feasibility of the corner store as a sustainable venue to increase produce consumption in underserved communities.

Cluster Mergers, Radio Halos and Hard X-ray Tails: A Statistical Magneto-Turbulent Model

description: There is now firm evidence that the ICM consists of a mixture of hot plasma, magnetic fields and relativistic particles. The most important evidences for non-thermal phenomena in galaxy clusters comes from the diffuse Mpc-scale synchrotron radio emission (radio halos) observed in a growing number of massive clusters (Feretti 2003) and from hard X-ray (HXR) excess emission (detected in a few cases) which can be explained in terms of IC scattering of relativistic electrons off the cosmic microwave background photons (Fusco-Femiano et al. 2003). There are now growing evidences that giant radio halos may be naturally accounted for by synchrotron emission from relativistic electrons reaccelerated by some kind of turbulence generated in the cluster volume during merger events (Brunetti 2003). With the aim to investigate the connection between thermal and non-thermal properties of the ICM, we have developed a statistical magneto-turbulent model which describes the evolution of the thermal and non-thermal emission from clusters. We calculate the energy and spectrum of the magnetosonic waves generated during cluster mergers, the acceleration and evolution of relativistic electrons and thus the resulting synchrotron and inverse Compton spectra. Here we give a brief description of the main results, while a more detailed discussion will be presented in a forthcoming paper. Einstein-De Sitter cosmology, $H_o=50$ km $s^{-1}$$Mpc^{-1}$, $q_o=0.5$, is assumed.

title: Modifying T cell differentiation via protein based delivery of signalling attenuators
Creators: name: Veldhoen, Marc
Publisher: name: The Open University
Year: 2003

description: In recent years, evidence has accumulated that hierarchical thresholds for proliferation and differentiation may determine the generation of various effector T cell modes. It is as yet poorly understood, however, how changes in TCR-mediated signalling and its downstream signalling cascades drive the differentiation of the naive T cell into different response modes. This project aims to study whether manipulation of the signalling pathways directly downstream of the TCR/CD28 receptor can result in distinct functional differentiation of monoclonal CD4+ T cell populations with known antigenic specificity.

 To this end, two potential protein transfer mechanisms were tested for their suitability to act as inert delivery vehicles to deliver proteins into ex vivo naive T cells. The B subunit pentamer of enterotoxin B induced high levels apoptosis in naive T cells, which precluded its use as an inert delivery vehicle. The protein transduction domain of the HIV-1 protein Tat, however, did not influence T cell physiology and was subsequently successfully tested for its ability to transduce ex vivo T cells genetically fused to large proteins.

 Two fusion partners, the kinase truncated forms of ZAP-70 and Lck, were tested for their ability to interfere with TCR-mediated signalling. The kinase- truncated form of ZAP-70 showed a concentration dependent effect on calcium mobilisation, which was reliant on the strength of CD3 crosslinking. The kinase- truncated form of Lck also altered calcium mobilisation in a concentration dependent manner, but independent of TCR strength. In addition, it was shown to influence T cell activation, to be capable of altering the signal transduction cascade after T cell priming, and to dramatically change the cytokine profile.

description: Pop III stars are the first stars in the universe. They do not contain metals and their formation and evolution may be different from that of stars of later generations. In fact, according to the theory of star formation, Pop III stars might have very massive components ($\sim 100 - 10000M_\odot$). In this paper, we compute the spherically symmetric gravitational collapse of these Pop III massive stars. We solve the general relativistic hydrodynamics and neutrino transfer equations simultaneously, treating neutrino reactions in detail. Unlike supermassive stars ($\gtrsim 10^5 M_\odot$), the stars of concern in this paper become opaque to neutrinos. The collapse is simulated until after an apparent horizon is formed. We confirm that the neutrino transfer plays a crucial role in the dynamics of gravitational collapse, and find also that the $β$-equilibration leads to a somewhat unfamiliar evolution of electron fraction. Contrary to the naive expectation, the neutrino spectrum does not become harder for more massive stars. This is mainly because the neutrino cooling is more efficient and the outer core is more massive as the stellar mass increases. Here the outer core is the outer part of the iron core falling supersonically. We also evaluate the flux of relic neutrino from Pop III massive stars. As expected, the detection of these neutrinos is difficult for the currently operating detectors. However, if ever observed, the spectrum will enable us to obtain the information on the formation history of Pop III stars. We investigate 18 models covering the mass range of $300 - 10^4 M_\odot$, making this study the most detailed numerical exploration of spherical gravitational collapse of Pop III massive stars. This will also serve as an important foundation for multi-dimensional investigations.

description: The study of sampling signals on graphs, with the goal of building an analog of sampling for standard signals in the time and spatial domains, has attracted considerable attention recently. Beyond adding to the growing theory on graph signal processing (GSP), sampling on graphs has various promising applications. In this article, we review current progress on sampling over graphs focusing on theory and potential applications. Although most methodologies used in graph signal sampling are designed to parallel those used in sampling for standard signals, sampling theory for graph signals significantly differs from the theory of Shannon--Nyquist and shift-invariant sampling. This is due in part to the fact that the definitions of several important properties, such as shift invariance and bandlimitedness, are different in GSP systems. Throughout this review, we discuss similarities and differences between standard and graph signal sampling and highlight open problems and challenges.

First, Monte Carlo integration is performed in a nine-dimensional parameter space of Klein's podel I [Klein (1950)]. Second, Monte Carlo is used as a tool for the elicitation of a uniform prior on a finite region by making use of several types of prior information. Third, special attention is given to procedures for the construction of importance functions which make use of nonlinear optimization methods.

description: One of the possible approaches to constructing models and methods for optimal marketing planning of an enterprise is considered, allowing to increase the efficiency of marketing decisions made under conditions of parametric uncertainty (incomplete information about the parameters of the production system and the external environment). A set of models and algorithms for their analysis is proposed, based on methods of system analysis, probability theory and stochastic programming and intended for planning sales volumes of products of single-stage stochastic production systems. Issues of practical application of the proposed approach to the formation of a marketing strategy for mass production of electronic products are discussed.
title: Role of nitric oxide in the maturation process of human dendritic cells
Creators: name: Paolucci, Clara
Publisher: name: The Open University
Year: 2003

description: Nitric oxide (NO) generated by phagocytes at inflammation sites contributes to regulate immune responses through both autocrine and paracrine actions on bystander cells. Among the latter are dendritic cells (DCs). Little is known about regulation of DC function by NO, especially in the human system. In this thesis I report about the role of NO in two specific aspects of human DC maturation: i.e. endocytosis and ability to induce T cell activation. At variance with rodents, human DCs express the inducible isoform of the NO synthase neither when immature, nor after various treatment which induce DC maturation, indicating that regulation of these cells may occur only through exogenous NO. Exposure of DCs to NO, released by either bystander phagocytes or NO donors, reversed the inhibition of endocytosis induced by TNF-a. The intracellular accumulation of ceramide induced by TNF-a was also inhibited by NO. In addition, NO was found to exert an inhibitory effect downstream of the TNF-a-triggered ceramide accumulation, since NO donors reversed the inhibition of endocytosis induced by the cell-permeant C2-ceramide. I then studied the role of NO on DC ability of triggering T cell activation. DCs were exposed to the NO donor DETA-NO during their maturation process induced by treatment with TNF-a or lipopolysaccharide, or by CD40 activation. After exposure to DETA-NO, DCs exhibit a significantly increased ability to activate T lymphocytes stimulated by mycobacterial antigens, Staphylococcus aureus Cowen strain B, allo-antigens, or cross-linking of the CD3-T cell receptor complex. This effect persists after removal of DETA-NO and is due to enhanced release by DCs of soluble factors, in particular IL-12. All the effects described above were mimicked by the membrane-permeant cyclic GMP analogue, 8-Br cyclic GMP, and prevented by inhibition of the soluble guanyly 1-cyclase. The cGMP dependent modulation of DC function reported here is due to a synergism between NO and the various maturation stimuli since neither the changes in endocytic function nor the enhanced T cell activation and IL-12 release were observed after DC exposure to DETA-NO only. These results provide the first evidence that NO acts as a co-signalling molecule regulating human DC response to maturation stimuli.
Increasing team ideation by sequencing the task type and content

description: While ideation is accepted as integral to the design process, the methods for facilitating ideation within teams are not as well understood. We propose and test the usefulness of sequencing variations in task type and content to facilitate team ideation in a team creativity task. In a repeated measures design we assessed team ideation (96 teams) before and after exposure to one of three randomized variations in sequences of task type and content. After this intervention, teams exposed to tasks that were dissimilar in content or type experienced the highest increase in variety of ideas produced. Our results are relevant for practice as they suggest that structuring team tasks to alternate content may help to improve team creativity.

description: This report presents an investigation into the opportunity for the UBC Farm to produce biomass for energy production at the UBC Bioenergy Research and Demonstration Facility (BRDF). The goal of this investigation is to contribute to UBC's e ort to reduce greenhouse gas emissions in an economically and socially responsible manner. The stakeholder for the project is Kate Menzies, Agroforesty Coordinator at UBC Farm. The land considered to be available for use in the presented analysis was 500m² of marginal lands and hedgerows at UBC Farm. The extent of this area was measured in person and estimated using maps (Google Maps, 2013). To manage the amount of research required for the project, miscanthus giganteus, switchgrass and hybrid poplar were investigated and compared on several qualitative and quantitative criteria designated by UBC Farm and the BRDF. The result of this evaluation was that miscanthus giganteus is the most beneficial crop to produce. Its expected annual yield will increase over time, achieving a maximum of 1 ton of dry matter after three to four years. At maximum yield rates, it will supply 0.008% of the BRDFs annual biofuel consumption (Nexterra Energy Corp., 2013). Assuming the BRDF is operating in thermal mode at all times, this accounts for 1.6 lbs/hr of steam production and a reduction of 0.4 tons of greenhouse gas (GHG) emissions per year (Nexterra Energy Corp., 2013). The triple bottom line assessment conducted for growing miscanthus giganteus indi- cates that UBC Farm will need to invest $460 to begin the project. This project will operate at a net loss of $205 per year afterwards. However, this is a sound investment considering the environmental and social benefits of the project. Environmentally, the project needs to be increased in scale to significantly reduce UBC's GHG emissions, but there are other positives such as reduced soil erosion to consider. Socially, there is the potential for this project to have a significant impact in that it will broaden interest and understanding of the production of bioenergy and create new relationships within UBC's community and beyond. Overall, UBC stands to benefit from this project from an investment point of view, and it is recommended that UBC consider taking action in the near future.

description: J.M. Herndon in 90-s proposed a natural nuclear fission georeactor at the center of the Earth with a power output of 3-10 TW as an energy source to sustain the Earth magnetic field. R.S. Raghavan in 2002 y. pointed out that under certain condition antineutrinos generated in georeactor can be detected using massive scintillation detectors. We consider the underground Baksan Neutrino Observatory (4800 m.w.e.) as a possible site for developments in Geoneutrino physics. Here the intrinsic background level of less than one event/year in a liquid scintillation ~1000 target ton detector can be achieved and the main source of background is the antineutrino flux from power reactors. We find that this flux is ~10 times lower than at KamLAND detector site and two times lower than at Gran Sasso laboratory and thus at Baksan the georeactor hypothesis can be conclusively tested. We also discuss possible search for composition of georector burning nuclear fuel by analysis of the antineutrino energy spectrum.

description: In deterministic sequencing and scheduling problems, jobs are to be processed on machines of limited capacity. We consider an extension of this class of problems, in which the jobs require the use of additional scarce resources during their execution. A classification scheme for resource constraints is proposed and the computational complexity of the extended problem class is investigated in terms of this classification. Models involving parallel machines, unit-time jobs and the maximum completion time criterion are studied in detail; other models are briefly discussed.
title: The quorum sensing system and the stationary phase RpoS sigma factor of the onion pathogen Burkholderia cepacia Gv 1 type strain, ATCC 25416
Creators: name: Aguilar Peña, Claudio Andrés
Publisher: name: The Open University
Year: 2003

description: Bacterial strains belonging to Burkholderia cepacia can be human opportunistic pathogens, plant growth promoting and have remarkable catabolic activity. Recently, B. cepacia has been thus far subdivided into several Genomovars comprising what is now known as the B. cepacia complex. In this thesis, the quorum sensing system of a rot onion Genomovar I type strain, ATCC 25416 is described. Quorum sensing is a cell-density dependent regulatory response, which involves the production of A-acyl homoserine lactones signal molecules (HSLs). The cep locus of B. cepacia ATCC 25416 coding for LuxI family CepI and LuxR family CepR proteins has been identified and characterised. The two genes have been inactivated in the chromosome and shown that CepI is responsible for the biosynthesis of a C6-HSL and a C8-HSL and that the cep locus regulates protease production as well as onion pathogenicity. A cep-lacZ based sensor plasmid has been constructed and used to demonstrate that CepR was specific for C8-HSL and not for C6-HSL, that a cepR knock out mutant synthesised 70 % less HSLs and that CepR had a higher specificity towards long chain HSLs. With the aid of this sensor plasmid, a novel technique aimed to identify quorum sensing-controlled (QSC) genes in B. cepacia is described. In addition, the cloning and characterization of the stationary phase sigma factor gene rpoS of B. cepacia ATCC 25416 is also described. This RpoS was found to be 74 % identical to the RpoS of Ralstonia solanacearum but rather distant from other RpoS of gram-negative y-Proteobacteria. It was established that quorum sensing in B. cepacia has a negative effect on rpoS expression as determined using an rpoS-lacZ transcriptional fusion; on the other hand, rpoS-null mutants displayed no difference in the accumulation of HSL signal molecules.

description: We report on linewidth analysis of optical transitions in InAs/GaAs coupled quantum dots as a function of bias voltage, temperature, and tunnel coupling strength. A significant line broadening up to 100 $μ$eV is observed at hole tunneling resonances where the coherent tunnel coupling between spatially direct and indirect exciton states is maximized, corresponding to a phonon-assisted transition rate of 150 ns${}^{-1}$ at 20 K. With increasing temperature, the linewidth shows broadening characteristic of single-phonon transitions. The linewidth as a function of tunnel coupling strength tracks the theoretical prediction of linewidth broadening due to phonon-assisted transitions, and is maximized with an energy splitting between the two exciton branches of 0.8$-$0.9 meV. This report highlights the linewidth broadening mechanisms and fundamental aspects of the interaction between these systems and the local environment.
