description: Fatty acid esters of 3-monochloropropane-1,2-diol (3-MCPD), 2-monochloropropanediol-1,3-diol (2-MCPD), and glycidol are heat-induced processing contaminants formed during the deodorisation step of edible oil refining. Because these compounds are potentially carcinogenic and/or genotoxic, their presence in refined oils and fats and foods containing these oils/fats poses possible health concerns. In particular, formula-fed infants may be exposed to these compounds due to their presence in commercial infant formulas. For this reason, in 2018, the European Union established maximum limits for glycidyl esters in oils/fats and infant formulas and recently, as of January 2021, implemented regulations for the sum of free 3-MCPD and 3-MCPD fatty acid esters as well. This work involved the analysis of 3-MCPD and glycidyl ester contents in 45 infant formula products purchased from German supermarkets in 2019. The data produced in this study showed that average contaminant concentrations across all manufacturers were exceptionally low, with 100% of the products analysed falling below the current EU regulation for glycidyl esters in powdered formulas and 96% of the products analysed meeting the recently implemented regulation for the sum of free and bound 3-MCPD. In addition, a comparison of the 2019 data set to occurrence data collected for German formulas purchased in 2015 showed that average bound 3-MCPD and glycidol concentrations have decreased (from 0.094 to 0.054 µg g−1 and from 0.010 to 0.006 µg g−1, respectively), likely indicating that additional/improved mitigation measures for reducing contaminant concentrations in infant formulas have been implemented over the 4-year period. The data collected in this occurrence study are suitable for estimating levels of exposure to these compounds for German infants.

description: This study utilises data from authoritative sources such as NICE, NHS Resolution and NHS Improvement to investigate the impact of litigation and compensation for harm (LCFH) on the health economics of Planned Caesarean Section (PCS) and Planned Vaginal Birth (PVB). These costs have not previously been included in health economics conducted by NICE and reveal that in England in 2017/18 NHS obstetric indemnity funding accounted for additional costs averaging £1,469 per birth. It also reveals that current funding lags behind the true anticipated costs, which are thought likely to reach £4,154-£4,748 /birth over time. Applying analysis of the breakdown of claims to these figures shows that 83% of the LCFH costs are related to planned mode of delivery in a ratio of 8.8/1 PVB/PCS. This results in PCS being £439 per birth cheaper than PVB based on current funding but that the true difference in cost may reach £2,452-£3,244 over time.

description: The evolution of white dwarfs is essentially a gravothermal process of cooling in which the basic ingredients for predicting their evolution are well identified, although not always well understood. There are two independent ways to test the cooling rate. One is the luminosity function of the white dwarf population, and another is the secular drift of the period of pulsation of those individuals that experience variations. Both scenarios are sensitive to the cooling or heating time scales, for which reason, the inclusion of any additional source or sink of energy will modify these properties and will allow to set bounds to these perturbations. These studies also require complete and statistical significant samples for which current large data surveys are providing an unprecedented wealth of information. In this paper we review how these techniques are applied to several cases like the secular drift of the Newton gravitational constant, neutrino magnetic moments, axions and weakly interacting massive particles (WIMPS).

description: A periodically driven quantum capacitor may function as an on-demand single electron source as it has recently been demonstrated experimentally. However, the accuracy at which single electrons are emitted is not yet understood. Here we consider a conceptually simple model of a quantum capacitor and find analytically the noise spectrum as well as the counting statistics of emitted electrons. We find that the failure rate of the capacitor can be arbitrarily small when operated under favorable conditions. Our theoretical predictions may be tested in future experiments.

description: We present SummaryLens, a concept and prototype for a mobile tool that leverages automated text summarization to enable users to quickly scan and summarize physical text documents. We further combine this with a text-to-speech system to read out the summary on demand. With this concept, we propose and explore a concrete application case of bringing ongoing progress in AI and Natural Language Processing to a broad audience with interactive use cases in everyday life. Based on our implemented features, we describe a set of potential usage scenarios and benefits, including support for low-vision, low-literate and dyslexic users. A first usability study shows that the interactive use of automated text summarization in everyday life has noteworthy potential. We make the prototype available as an open-source project to facilitate further research on such tools.

description: We investigate the equilibrium properties of a quasi-two-dimensional degenerate boson-fermion mixture (DBFM) with a bosonic vortex-antivortex superposed state (VAVSS) using a quantum-hydrodynamic model. We show that, depending on the choice of parameters, the DBFM with a VAVSS can exhibit rich phase structures. For repulsive boson-fermion (BF) interaction, the Bose-Einstein condensate (BEC) may constitute a petal-shaped "core" inside the honeycomb-like fermionic component, or a ring-shaped joint "shell" around the onion-like fermionic cloud, or multiple segregated "islands" embedded in the disc-shaped Fermi gas. For attractive BF interaction just below the threshold for collapse, an almost complete mixing between the bosonic and fermionic components is formed, where the fermionic component tends to mimic a bosonic VAVSS. The influence of an anharmonic trap on the density distributions of the DBFM with a bosonic VAVSS is discussed. In addition, a stability region for different cases of DBFM (without vortex, with a bosonic vortex, and with a bosonic VAVSS) with specific parameters is given.

description: In the European Union, the use of veterinary drugs belonging to the A6 group is prohibited in food-producing animals according to Commission Regulation (EU) No. 2010/37. The aim of this study was to improve the analytical control strategy by developing a single method to analyse residues of prohibited pharmacologically active substances in milk. For this, a single method was developed to analyse 16 prohibited pharmacologically active substances belonging to five different substance classes at required or recommended levels: nitroimidazoles at 3 μg kg−1, nitrofurans at 0.5 μg kg−1, chloramphenicol at 0.1 μg kg−1, dapsone at 5 μg kg−1 and chlorpromazine at 1 μg kg−1. Milk sample preparation started with an acid hydrolysis combined with a derivatisation. These steps were followed by a clean-up consisting of a dispersive solid-phase extraction and a liquid–liquid extraction. Finally, the sample extracts were analysed by liquid chromatography combined with tandem mass spectrometry, operating alternately in the positive and negative mode. The method was fully validated according to Commission Decision 2002/657/EC for bovine milk and additionally validated for caprine milk. The validation proved that the method is highly effective to detect and confirm all 16 substances in bovine and caprine milk and, additionally to quantify 15 of these substances in bovine milk and 13 of these substances in caprine milk. This study resulted in a new multi-class method to detect, quantify and confirm the identity of 16 prohibited pharmacologically active substances belonging to five different substance classes in two types of milk.

description: A strategy is proposed to realize robust transport in time reversal invariant photonic system. Using numerical simulation and microwave experiment, we demonstrate that a chiral guided mode in the channel of a three-dimensional dielectric woodpile photonic crystal is immune to the scattering of a square patch of metal or dielectric inserted to block the channel. The chirality based robust transport can be realized in nonmagnetic dielectric materials without any external field.

description: We combine new high sensitivity ultraviolet (UV) imaging from the Wide Field Camera 3 (WFC3) on the Hubble Space Telescope (HST) with existing deep HST/Advanced Camera for Surveys (ACS) optical images from the Great Observatories Origins Deep Survey (GOODS) program to identify UV-dropouts, which are Lyman break galaxy (LBG) candidates at z~1-3. These new HST/WFC3 observations were taken over 50 sq.arcmin in the GOODS-South field as a part of the Early Release Science program. The uniqueness of these new UV data is that they are observed in 3 UV/optical (WFC3 UVIS) channel filters (F225W, F275W and F336W), which allows us to identify three different sets of UV-dropout samples. We apply Lyman break dropout selection criteria to identify F225W-, F275W- and F336W-dropouts, which are z~1.7, 2.1 and 2.7 LBG candidates, respectively. Our results are as follows: (1) these WFC3 UVIS filters are very reliable in selecting LBGs with z~2.0, which helps to reduce the gap between the well studied z~>3 and z~0 regimes, (2) the combined number counts agrees very well with the observed change in the surface densities as a function of redshift when compared with the higher redshift LBG samples; and (3) the best-fit Schechter function parameters from the rest-frame UV luminosity functions at three different redshifts fit very well with the evolutionary trend of the characteristic absolute magnitude, and the faint-end slope, as a function of redshift. This is the first study to illustrate the usefulness of the WFC3 UVIS channel observations to select z<3 LBGs. The addition of the new WFC3 on the HST has made it possible to uniformly select LBGs from z~1 to z~9, and significantly enhance our understanding of these galaxies using HST sensitivity and resolution.

description: Different from the skyrmion driven by the Dzyaloshinskii-Moriya interaction in non-centrosymmetric materials, the skyrmionic texture in centrosymmetric magnet may possess the extra internal degrees of freedom, which greatly enrich its morphologies, imply the continuous deformation allowed by topological protection, and enable flexible tunability and potential functionality. To describe the internal degree of freedom to full extent, the conventional integer-valued scalar vorticity is extended into a vector vorticity with continuous rotation allowed. The further simplified vorticity angle, together with helicity angle, represents the whole rotation freedom of spin space. The centrosymmetric magnet with frustration provides a perfect platform for realizing a controllable manipulation on these internal degrees of freedom, where the magnetic field can be applied to tune vorticity continuously in both crystal and isolated forms of skyrmionic texture, and the helicity can be further controlled by electric field. Moreover, the simulation reveals the distinctive dynamic effects related to the vorticity modulation, namely, a straight motion can be generated by rotating magnetic field to tune vorticity, and the vorticity can also be controlled to modulate the dynamics induced by the spin polarized current.

description: We show that in most conformal field theories the condition of the energy flux positivity, proposed by Hofman and Maldacena, is equivalent to the absence of ghosts. At finite temperature and large energy and momenta, the two-point functions of the stress energy tensor develop lightlike poles. The residues of the poles can be computed, as long as the only spin two conserved current, which appears in the stress energy tensor OPE and acquires nonvanishing expectation value at finite temperature, is the stress energy tensor. The condition for the residues to stay positive and the theory to remain ghost free is equivalent to the condition of positivity of energy flux.

description: Theoretical and empirical studies have suggested that climate, soils, and topography are the primary drivers of aboveground biomass in forests. Yet, the direct effects of these drivers may be mediated by indirect effects, such as species diversity and structural diversity. This study investigates the relationships between climate, topography, soil fertility, species diversity, structural diversity, and aboveground biomass (AGB) using Structural Equation Modeling (SEM) to distinguish indirect and direct causal relationships. We conducted this study in longleaf pine (Pinus palustris)-dominated forests in the southeastern United States (SEUS), using United States Department of Agriculture Forest Service inventory data from 2015 to 2019. The longleaf pine ecosystems of the SEUS are of great importance due to their rich biodiversity and unique ecological functions, but they also provide an opportunity for scientific studies across a large ecological gradient because they exist across a wide range of edaphic conditions. However, studies in longleaf pine have primarily focused on stand structure, regeneration processes, prescribed fire practices, and groundcover restoration, leaving a knowledge gap regarding AGB in this ecosystem. We hypothesized that (1) climate, topography, and soil fertility would influence AGB through positive indirect effects; (2) structural diversity rather than species diversity would strongly mediate the response of AGB to climate, topography, and soil fertility; and (3) species diversity and structural diversity would be positively correlated, with structural diversity positively impacting AGB across coarse scale ecological gradients. Structural diversity could be important in predicting AGB because it reflects the horizontal complexity of the forest stand. Our results show that mean annual temperature and slope had considerable direct negative and positive impacts on AGB, respectively. Additionally, soil fertility, elevation, and precipitation indirectly impacted AGB by affecting species diversity. Specifically, AGB decreased in highly fertile soils, whereas elevation and precipitation led to an increase in tree species diversity. Structural diversity had a direct positive influence on AGB, while species diversity played an indirect role by promoting structural diversity. While there are diverse objectives for managing longleaf pine, management that promotes high levels of stand structural diversity may strengthen the stock of longleaf pine forest AGB, which could be especially important in the face of changing climatic conditions. Our findings emphasize the importance of integrating climate resilience and carbon storage goals into forest management practices.

description: Stock Market can be easily seen as one of the most attractive places for investors, but it is also very complex in terms of making trading decisions. Predicting the market is a risky venture because of the uncertainties and nonlinear nature of the market. Deciding on the right time to trade is key to every successful trader as it can lead to either a huge gain of money or totally a loss in investment that will be recorded as a careless trade. The aim of this research is to develop a prediction system for stock market using Fuzzy Logic Type2 which will handle these uncertainties and complexities of human behaviour in general when it comes to buy, hold or sell decision making in stock trading. The proposed system was developed using VB.NET programming language as frontend and Microsoft SQL Server as backend. A total of four different technical indicators were selected for this research. The selected indicators are the Relative Strength Index, William Average, Moving Average Convergence and Divergence, and Stochastic Oscillator. These indicators serve as input variable to the Fuzzy System. The MACD and SO are deployed as primary indicators, while the RSI and WA are used as secondary indicators. Fibonacci retracement ratio was adopted for the secondary indicators to determine their support and resistance level in terms of making trading decisions. The input variables to the Fuzzy System is fuzzified to Low, Medium, and High using the Triangular and Gaussian Membership Function. The Mamdani Type Fuzzy Inference rules were used for combining the trading rules for each input variable to the fuzzy system. The developed system was tested using sample data collected from ten different companies listed on the Nigerian Stock Exchange for a total of fifty two periods. The dataset collected are Opening, High, Low, and Closing prices of each security.

Geochemical and molecular taxonomic approaches revealed novel and deeply branching microbial assemblages mediating anaerobic hydrocarbon degradation, metal respiration and C1 utilization pathways. These results open a window into the origin and adaptive evolution of microbial life within recalcitrant hydrocarbon matrices, and establish the site as a useful analog for the liquid hydrocarbon environments on Saturn's moon Titan.

description: Early detection of breast cancer is a powerful tool towards decreasing its socioeconomic burden. Although, artificial intelligence (AI) methods have shown remarkable results towards this goal, their "black box" nature hinders their wide adoption in clinical practice. To address the need for AI guided breast cancer diagnosis, interpretability methods can be utilized. In this study, we used AI methods, i.e., Random Forests (RF), Neural Networks (NN) and Ensembles of Neural Networks (ENN), towards this goal and explained and optimized their performance through interpretability techniques, such as the Global Surrogate (GS) method, the Individual Conditional Expectation (ICE) plots and the Shapley values (SV). The Wisconsin Diagnostic Breast Cancer (WDBC) dataset of the open UCI repository was used for the training and evaluation of the AI algorithms. The best performance for breast cancer diagnosis was achieved by the proposed ENN (96.6% accuracy and 0.96 area under the ROC curve), and its predictions were explained by ICE plots, proving that its decisions were compliant with current medical knowledge and can be further utilized to gain new insights in the pathophysiological mechanisms of breast cancer. Feature selection based on features' importance according to the GS model improved the performance of the RF (leading the accuracy from 96.49% to 97.18% and the area under the ROC curve from 0.96 to 0.97) and feature selection based on features' importance according to SV improved the performance of the NN (leading the accuracy from 94.6% to 95.53% and the area under the ROC curve from 0.94 to 0.95). Compared to other approaches on the same dataset, our proposed models demonstrated state of the art performance while being interpretable.

description: The topology of isoenergetic surfaces in reciprocal space for simple (sc), body-centered (bcc), and face-centered (fcc) cubic lattices is investigated in detail in the tight-binding approximation, taking into account the transfer integrals between the nearest and next neighbors $t$ and $t'$. It is shown that, for values $τ= t'/t = τ_\ast$ corresponding to a change in the topology of surfaces, lines and surfaces of $\mathbf k$-van Hove points can be formed. With a small deviation of $τ$ from these singular values, the spectrum in the vicinity of the van Hove line (surface) is replaced by a weak dependence on $\mathbf k$ in the vicinity of several van Hove points that have a giant mass proportional to $|τ- τ_ \ast|^{-1}$. Singular contributions to the density of states near peculiar $τ$ values are considered; analytical expressions for the density of states being obtained in terms of elliptic integrals. It is shown that in a number of cases the maximum value of the density of states is achieved at energies corresponding not to $\mathbf{k}$-points on the Brillouin zone edges, but to its internal points in highly symmetrical directions. The corresponding contributions to electron and magnetic properties are treated, in particular, in application to weak itinerant magnets.

Publisher: name: University of British Columbia
Year: 2024

description: Long-term prevention of implant-associated infection (IAI) remains as a challenge. Despite advances in the development of antibiofilm coatings, current coating technologies fail to provide long-term prevention of IAIs. One of the most widely studied antimicrobial agents for generation of release-killing coatings is silver. However, current silver-based antibiofilm coatings suffer from major limitations that need to be addressed for widespread use in medical devices/implants. This thesis explores a new generation of silver-based antibiofilm coatings with long-term activity, high biocompatibility, and adaptability to medical devices and materials with diverse surface chemistry. In Chapter 2, the development of film-forming silver nanoparticles for generation of biocompatible durable long-acting coatings with zero bacterial colonization (for 28 days) is reported. The combination of two different molecular weight polymers with catechol results in effective incorporation of silver nanoparticles into a lubricious coating via a simple coating process. The optimal coating showed excellent broad-spectrum activity against eight different bacterial strains including difficult-to-kill and stone-forming bacteria. In Chapter 3, the development of a robust antibiofilm coating with long-term activity and high adaptability to virtually any arbitrary object was reported. The coating described in Chapter 2 was utilized in combination with a water-miscible organic solvent to generate such coatings. The optimal coating fully suppressed bacterial growth in solution and on a surface over the long-term irrespective of the bacterial strain tested. The coating resulted in sustained release of silver over the long-term (28 days). The coating retained its excellent antibiofilm performance following different challenging tests. Antibiofilm efficacy and excellent biocompatibility of the coating were demonstrated in vivo using mice and rat models. In Chapter 4, the generation of film-forming supramolecular assemblies utilizing catechol chemistry in combination with a low molecular weight amphiphilic polymer is discussed. The supramolecular assemblies resulted in relatively thick coatings with great surface coverage and high hydrophilicity. The optimal catechol/polymer coating was highly effective in inhibition of biofilm formation over the long-term. Based on this work, three sets of novel antibiofilm coatings with long-term activity were developed utilizing catechol chemistry in combination with silver and hydrophilic polymers.

description: As a result of this work, a vertical layout of the territory of low-rise blocked development was carried out with the concomitant design of a rain sewer system. Measures were taken to reduce water in open planar sports facilities. The volumes of surface water discharged for treatment and their pollution indicators were calculated, and the treatment efficiency was calculated. In accordance with the calculation results, a technological scheme of treatment is proposed and a sewage treatment plant is selected. In addition to this, a rain garden was designed in the recreation area, the task of which is to collect, retain, purify and absorb storm drains from the park. For it, a calculation was made that determines the absorbed ability, and plants are selected that allow the garden to function.

description: We apply factorization and eikonal methods from gauge theories to scattering amplitudes in gravity. We hypothesize that these amplitudes factor into an IR-divergent soft function and an IR-finite hard function, with the former given by the expectation value of a product of gravitational Wilson line operators. Using this approach, we show that the IR-divergent part of the n-graviton scattering amplitude is given by the exponential of the one-loop IR divergence, as originally discovered by Weinberg, with no additional subleading IR-divergent contributions in dimensional regularization.

Behavioural economics analysis of recreational and medical cannabis
Creators: name: Crosby, Kimberly Anne
Publisher: name: University of British Columbia
Year: 2022

description: Cannabis is among the most widely used psychoactive substances in Canada and there is increasing need to examine the reinforcing effects of the substance. Hypothetical cannabis purchasing tasks have been used to describe the reinforcing value of psychoactive substances. The present body of research examined the utility of cannabis purchasing tasks for modelling recreational and medical cannabis use. It adds to the current body of literature by examining across units of consumption (hits vs grams), the impact of THC potency on recreational use, and the potential for cannabis to serve as a substitute for alcohol or prescription opioid medication. Data were collected from young adult recreational cannabis users (N = 250) and medical cannabis users recruited through a medical cannabis network (N = 410). Participants were presented with hypothetical purchasing tasks asking them how many units (hits or grams) of cannabis they would purchase at 17 price points (ranged $0.00 -$500). Recreational users were randomly assigned to low and high THC conditions. Demand curves were modelled using an Exponentiated Demand equation yielding five distinct metrics theorized to be associated with reinforcing value of cannabis which were compared to cannabis use variables and ratings of pain for medical users. Secondary purchasing tasks asked participants how many units of cannabis they would purchase with concurrently available alcohol and prescription pain medication at both static and varying prices. With respect to potency, there was no difference in demand characteristics across high and low THC cannabis among recreational users. With regard to unit of measurement, a clearer association between demand characteristics and cannabis use variables was apparent for grams of cannabis purchased than hits of cannabis for recreational cannabis. For medical cannabis users, more apparent associations between demand and cannabis use were evident for hits purchased than grams. For both recreational and medical users, cannabis did not serve as a substitute for alcohol. For medical users, prescription pain medication may serve as a partial substitute for cannabis.

description: Perturbing a Virasoro minimal model by the (1,3) primary bulk field results in an integrable field theory. In this paper, an infinite set of commuting conserved charges is obtained by considering defects: a one-parameter family of perturbed defect operators is given, and it is shown that these operators mutually commute, that they commute with the Hamiltonian of the perturbed CFT, and that they satisfy a T-system functional relation. The formulation in terms of perturbed defects is a modification of the original prescription for such charges by Bazhanov, Lukyanov and Zamolodchikov.
