description: Naphthenic acids (NAs) are a diverse group of carboxylic acids often associated with the toxicity of tailings, a petrochemical waste product generated by oil sands mining. NAs can be found in the acid extractable organic fraction (AEO) of the liquid component of tailings, oil sands process-affected water (OSPW). To assess the potential toxicity of AEO and individual NAs, a hatching bioassay using imaging and computer analysis was developed using the pond snail Lymnaea stagnalis. AEO dose-dependently decreased Lymnaea hatching percentage as well as delayed hatching at 25-50 mg/L AEO. This study also aimed to assess the effect different NA molecular architectures may have on NA toxicity. Varying degrees of hatching success and hatch time delays were observed following exposure of Lymnaea embryos to individual model NAs with diverse molecular structures. Molecular shape and dipole architecture of NAs may be an important factor in the ability of certain NAs to insert in biological membranes, indicating a possible relationship between NA structure and the degree of severity of NA toxicity. Finally, this study explored the hypothesis that the mechanism of NA toxicity is due to “narcosis” (which involves plasma membrane disruption via insertion of NAs’ hydrophobic alkyl tail) and may work in conjunction with PLA2-mediated fatty acyl hydrolysis. While the data did not support this hypothesis, it uncovered evidence for a hitherto unrecognized biological action of NAs; the binding of fatty acid-binding proteins.

description: We deform the anti-de Sitter algebra by adding additional generators $\mathcal{Z}_{ab}$, forming in this way the negative cosmological constant counterpart of the Maxwell algebra. We gauge this algebra and construct a dynamical model with the help of a constrained the BF theory. It turns out that the resulting theory is described by the Einstein-Cartan action with Holst term, and the gauge fields associated with the Maxwell generators $\mathcal{Z}_{ab}$ appear only in topological terms that do not influence dynamical field equations. We briefly comment on the extension of this construction, which would lead to a nontrivial Maxwell fields dynamics.

description: The Text Encoding initiative is conceived as a standard system designed to let interoperability between different projects working on analogous topics. However, interoperability is sometimes not easy to reach due to the different interpretation of tags made by each project or group. Given the variety of tags, there are several concepts that can be easily identified for many projects, such as  or , which referent is pretty clear and recognizable. There are some other tags, however, which can experience multiple interpretations, limited by the content of the attributes that modify them.

description: Recently, Near Earth Objects (NEOs) have been attracting great attention, and thousands of NEOs have been found to date. This paper examines the NEOs' orbital dynamics using the framework of an accurate solar system model and a Sun-Earth-NEO three-body system when the NEOs are close to Earth to search for NEOs with low-energy orbits. It is possible for such an NEO to be temporarily captured by Earth; its orbit would thereby be changed and it would become an Earth-orbiting object after a small increase in its velocity. From the point of view of the Sun-Earth-NEO restricted three-body system, it is possible for an NEO whose Jacobian constant is slightly lower than C1 and higher than C3 to be temporarily captured by Earth. When such an NEO approaches Earth, it is possible to change its orbit energy to close up the zero velocity surface of the three-body system at point L1 and make the NEO become a small satellite of the Earth. Some such NEOs were found; the best example only required a 410m/s increase in velocity.

Asteroseismic tuning of the magnetic star HR 1217 : understanding magnetism and stellar structure through MOST spacebased photometry
Creators: name: Cameron, Christopher J.
Publisher: name: University of British Columbia
Year: 2010

description: The chemically peculiar A (Ap) stars show extreme examples of astrophysical processes that have only recently been studied in detail in one other star—the Sun. These stars exhibit spectral anomalies caused by diffusion of some ionic species in a stellar atmosphere threaded by a strong (~ kG), organized magnetic field. A subset of the Ap stars rapidly oscillate (roAp) with periods ranging from 5 to 25 minutes. One of these roAp stars, HR 1217, is well studied with data from two global (ground-based) photometric campaigns that led to asteroseismic evidence of magnetically perturbed oscillation modes. This was the motivation to make HR 1217 a MOST space mission target. Our analysis of the almost 30 days of near-continuous MOST photometry on HR 1217 reveals a number of new periodicities that show spacings of ~ 15, 2.5, and 1.5 μHz. These new frequencies can be interpreted as magnetically perturbed oscillations and potentially second order spacings that could constrain the age and the magnetic interior of the star for the first time. These data are collected with a 95% duty cycle and reach a precision of 6 μmag, making this by far the best photometric data set on HR 1217. In addition, we present a grid of almost 52,000 stellar pulsation models including a large range of magnetic dipole field strengths (1-10 kG). This is the largest grid of stellar pulsation models of any Ap star to date and is critical to the interpretation of the MOST photometry. Our models can match the MOST observations to a fractional accuracy of about 0.05% with a mean deviation between theory and observation of a few μHz. A unique model match to the MOST observations could not be found. The results highlight the sensitivity to physics that has not been usually incorporated in Ap interior models, and the complex nature of the interaction of globally organized magnetic fields with stellar pulsation eigenmodes.

description: Abstract
This research aims to investigate the potential correlation of a fruit peel's lignin content and pH level to the paper produced from it, in hopes to optimize the paper industry's efficiency and sustainability by identifying the most suitable raw material (in this case, waste fruit peel) for each kind of paper production. 
For this experiment, banana (Musa paradisiaca), apple (Malus domestica), orange (Citrus sinensis), papaya (Carica papaya), grape (Vitis vinifera), and kiwi (Actinidia deliciosa) peels were utilized to give a proper variety of pH levels and lignin contents towards the formation of paper. There are 2 stages in making the fruit peel paper, first is the making of the pulp and second is the making of the paper itself.
To make the pulp, equal masses of fruit peels were boiled separately, first in a solution of water and baking soda, and afterwards only in water for 15 minutes each. Then, they were blended with waste paper that had been soaked in hot water with a ratio of 1:1, along with 50 ml of hot water and sieved. 
For the making of the paper, 5g of each fruit pulp was flattened on a surface of equal areas, dabbed with a towel and then left outside to dry under the sun for 2 days. Each paper's physical properties were then tested and compared with their respective lignin content and pH levels. The results showed that the lignin content of a fruit is proportional to the paper's stiffness and water absorbance ability, while its pH level did not have an effect.

description: Several studies have investigated the use of the first language (L1) in second language (L2) vocabulary teaching and learning. But so far, there is a scarcity of research that looks into this issue from the perspective of English learners of German. With the aim to fill this gap, a study was carried out that compares the effectiveness of the two experimental teaching conditions: L2 vocabulary instruction using L1 translation equivalents vs. L2 vocabulary instruction using L2 definitions of L2 words. This study also examines the role of the L2 proficiency level in the recall and retention of the L2 words under the two conditions. The participants were English learners of German. The results were compared across three different proficiency levels: beginner, intermediate and advanced. The research findings suggest that the use of the L1 facilitates the learning of the new L2 words and enhances the recall and retention of the newly learned L2 words.

description: Chemical flooding has been proved to be technically feasible and economically affordable to increase oil recovery in western Canada heavy oil reservoirs. Numerical studies of experimental results are carried out to improve the understanding of EOR mechanism of chemical flooding of heavy oil. Polymer flooding of heavy oil on the lab scale shows appreciable incremental oil recovery. However, when it is extended to field scale, the high recovery efficiency usually cannot be achieved. Scaling-up analysis of polymer flooding of heavy oil is conducted in this research. Twenty-eight dimensionless scaling groups are derived using inspectional analysis and validated by numerical simulation. The effect of each scaling group on oil recovery is examined by sensitivity analysis. Nine scaling groups dominating the process are identified. These dominant scaling groups can be used to design scaled experiments to predict field-scale oil recovery by polymer flooding in heavy oil reservoirs. A fast and effective method to examine the potential of enhanced heavy oil recovery by polymer flooding is developed in this study. Experimental results of sand-pack polymer flooding tests, for heavy oil samples with different viscosities, are analyzed. For each heavy oil sample, the polymer viscosity-sensitive range, within which the incremental recovery increases dramatically with increasing polymer viscosity, is different. To facilitate the evaluation of polymer flooding potential for heavy oils with various viscosities, the oil-water mobility ratio at the end of waterflooding is chosen as a normalization factor. Using normalization, an identical oil-water mobility ratio-sensitive range can be obtained for heavy oils with different viscosities. Based on the normalized relationship, the potential of enhanced heavy oil recovery by polymer injection can be quickly and effectively evaluated. Experimental results of chemical flooding of heavy oil suggested that lower interfacial tension resulted in lower heavy oil recovery. Theoretical analysis is conducted to give a reasonable explanation to the detrimental effect of interfacial tension reduction on heavy oil displacement. The effect of interfacial tension reduction induced by surfactant during heavy oil displacement is further studied by carrying out linear stability analysis, tube bundle calculation and numerical simulations.

description: We examine systematic differences in the derived X-ray properties of galaxy clusters as reported by three different groups: Vikhlinin et al. (2009a), Mantz et al. (2010b), and Planck Collaboration (2011b). The sample overlap between any two pairs of works ranges between 16 to 28 galaxy clusters in common. We find systematic differences in most reported properties, including the total cluster mass, M500. The most extreme case is an average 45% \pm 5% difference in cluster mass between the Planck Collaboration (2011b) and Mantz et al. (2010b), for clusters at z > 0.13 (averaged over 16 clusters). These mass differences induce differences in cluster observables defined within an R500 aperture. After accounting for aperture differences, we find very good agreement in gas mass estimates between the different groups. However, the soft-band X-ray luminosity, LX, core-excised spectroscopic temperature, TX, and gas thermal energy, YX = MgasTX display mean differences at the 5%-15% level. We also find that the low (z \leq 0.13) and high (z \geq 0.13) galaxy cluster samples in Planck Collaboration (2011b) appear to be systematically different: the YSZ/YX ratio for these two sub- samples is ln(YSZ/YX) = -0.06 \pm 0.04 and ln(YSZ/YX) = 0.08 \pm 0.04 for the low and high redshift sub-samples respectively.

description: Gas recharging process, as a supplemental technique for heavy oil reservoirs with thin layers, has attracted researchers’ attention. This thesis focused on three post-cold production process studies-CH4 recharging and depletion, CO2 and C3H8 huff-puff, and C3H8 flooding. Two 18m in length glass beads and sand packed cores and one 1.5m in length sand packed core were used for testing. The mechanisms of each process were investigated. Foamy oil flow under the solution gas drive mechanism was clearly observed during two long core methane depletion processes. The effects of core length and permeability on oil recovery were discussed. CT scanning technique was applied to capture core saturation variations after each process at the 1.5m core, which helped better understanding of the mechanisms of the three gas recharging processes and also was successfully applied to explain what happened in two long cores.

description: We investigate the Casimir force between a microfabricated elliptic cylinder (cylindrical lens) and a plate made of real materials. After a brief discussion of the fabrication procedure, which typically results in elliptic rather than circular cylinders, the Lifshitz-type formulas for the Casimir force and for its gradient are derived. In the specific case of equal semiaxes, the resulting formulas coincide with those derived previously for circular cylinders. The nanofabrication procedure may also result in asymmetric cylindrical lenses obtained from parts of two different cylinders, or rotated through some angle about the axis of the cylinder. In these cases the Lifshitz-type formulas for the Casimir force between a lens and a plate and for its gradient are also derived, and the influence of lens asymmetry is determined. Additionally, we obtain an expression for the shift of the natural frequency of a micromachined oscillator with an attached elliptic cylindrical lens interacting with a plate via the Casimir force in a nonlinear regime.

description: Reproducibility is essential to reliable scientific discovery in high-throughput experiments. In this work we propose a unified approach to measure the reproducibility of findings identified from replicate experiments and identify putative discoveries using reproducibility. Unlike the usual scalar measures of reproducibility, our approach creates a curve, which quantitatively assesses when the findings are no longer consistent across replicates. Our curve is fitted by a copula mixture model, from which we derive a quantitative reproducibility score, which we call the "irreproducible discovery rate" (IDR) analogous to the FDR. This score can be computed at each set of paired replicate ranks and permits the principled setting of thresholds both for assessing reproducibility and combining replicates. Since our approach permits an arbitrary scale for each replicate, it provides useful descriptive measures in a wide variety of situations to be explored. We study the performance of the algorithm using simulations and give a heuristic analysis of its theoretical properties. We demonstrate the effectiveness of our method in a ChIP-seq experiment.

description: Addressing the challenges posed by climate change, biodiversity loss, and environmental pollution requires comprehensive monitoring and effective data management strategies that are applicable across various scales in environmental system science. This paper introduces a versatile and transferable digital ecosystem for managing time series data, designed to adhere to the FAIR principles (Findable, Accessible, Interoperable, and Reusable). The system is highly adaptable, cloud-ready, and suitable for deployment in a wide range of settings, from small-scale projects to large-scale monitoring initiatives. The ecosystem comprises three core components: the Sensor Management System (SMS) for detailed metadata registration and management; time$.$IO, a platform for efficient time series data storage, transfer, and real-time visualization; and the System for Automated Quality Control (SaQC), which ensures data integrity through real-time analysis and quality assurance. The modular architecture, combined with standardized protocols and interfaces, ensures that the ecosystem can be easily transferred and deployed across different environments and institutions. This approach enhances data accessibility for a broad spectrum of stakeholders, including researchers, policymakers, and the public, while fostering collaboration and advancing scientific research in environmental monitoring.
Pore Network Modeling of Tight Gas Formations

description: Replicating pore topology/structure of tight gas reservoirs is essential for modeling fluid flow through such porous media. Constitutive relationships between the macroscopic properties of the medium can often help with such modeling efforts. This research demonstrates the validity of physically constructing a pore network for tight media based on Weibull lognormal skewed distributions. A randomized construction approach was developed to generate a realistic three-dimensional (3D) pore network of tight porous media to visualize fluid flow at the pore scale level. This approach offers flexibility in studying macroscopic property relationships with a pore throat structure. Further, the model was validated by generating an equivalent 3D pore network according to an experimentally derived throat size distribution. The distribution was obtained from an ambient mercury injection capillary pressure (MICP) analysis for 17 selected core samples from three Mesaverde tight gas sandstones basins in the U.S. The model used Weibull distributions to estimate other network properties, such as aspect ratio, throat length, and coordination number. Sensitivity analysis was performed to assess the effects of certain pore structures, including pore and throat radius, and coordination number, and geometries, such as square, circle and triangle, on the petrophysical and electrical properties of the physical representation of permeable and tight media. The study shows the importance of taking into consideration the internal pore structure to estimate the petrophysical and electrical properties. The estimated porosity, and simulated absolute liquid permeability and formation factor of the physically equivalent networks were in good agreement with the measured data iii obtained by Byrnes et al. (2009). A variation between the simulated absolute permeability to liquid and the measured routine gas permeability was encountered in core samples that have measured gas permeability and porosity smaller than 0.1md and 8%, respectively. Computed capillary pressure curves were in good agreement with lab measurements. It is concluded that pore – throat size distribution is important as pore connectivity in describing fluid flow properties and capacity of tight porous media.

Using routinely collected data to explore neurology outpatient services
Creators: name: Biggin, Frances
Publisher: name: Lancaster University
Year: 2023

description: In the UK a large amount of data is collected during the routine treatment of patients. This data, referred to as ‘routinely collected data’ within the health research community is increasingly being used in health research despite not being explicitly collected for this purpose. The fact that data collected for healthcare and administrative purposes is used for research can lead to a number of issues that need to be acknowledged and overcome. This thesis explores the benefits and limitations of using routinely collected data to research outpatient neurology services in the North-West of England. Neurology services in the UK are under pressure, with large variations in the level of service provided in different geographical areas. We analyse data from an outpatient neurology clinic in the northwest of England covering a diverse population which is dispersed over a large area. First the current research into neurology services using routinely collected data is explored using a systematic mapping review, identifying gaps and areas for further research. We then use data from the outpatient neurology clinic to explore the issues identified in three separate papers. Chapter four explores the number of patients using outpatient neurology services, what resources they require and the waiting times they experience. We show that there are a small number of diagnostic categories which account for 60% of new referrals to the clinic, and that waiting times vary by diagnostic category. Chapter five examines referrals for headache patients. Using standardised residuals from a Poisson regression we identify GP practices which have referred an unexpected number of headache patients. Chapter six uses State Sequence Analysis to observe patterns in the types of appointments patients attend over time. We show that there a number of common patterns of appointments and that these patterns are somewhat related to diagnosis. Taken together these papers show that routinely collected data can be successfully used to conduct useful and insightful research into outpatient neurology services. Our research also identifies key areas of limitation of using this type of data - such as missing data, the difficulty of accessing data, and the difficulties presented by the lack of diagnostic coding – for which solutions are proposed in the discussion.

B-splines are applied to approximate both the unknown baseline hazard function and the varying-coefficient functions. To improve the performance of the model, ridge penalty is added to the log-likelihood to penalize the roughness of the cumulative hazard function. Efficient sieve maximum likelihood estimation method is used for estimation. Simulation studies with the weighted bootstrap method are conducted to examine the finite-sample properties of the proposed estimators. We also present an analysis of renal function recovery data for illustration.

description: In many countries of the Global South, agri-food supply chains are transforming rapidly. One important feature of this transformation is growth in certain high-value agricultural subsectors, such as horticulture and cut-flowers for export. Growth in high-value agriculture often creates new employment opportunities, especially for women. More employment can lead to higher rural incomes, but the broader implications for social welfare are not yet sufficiently understood. Here, we use survey data from Ethiopia to investigate the effects of women’s employment in floriculture on child nutrition, focusing on children aged 0-5 years. We develop and estimate endogenous switching regressions to account for possible endogeneity. Our results suggest that maternal employment in floriculture negatively affects child height-for-age and weight-for-age z-scores (HAZ and WAZ). Exploration of the underlying mechanisms reveals that floriculture employment may influence time allocation, dietary quality, income, and female financial autonomy. Maternal employment is negatively associated with time spent on childcare and consumption of animal-sourced foods.

description: Amphetamine analogs are a class of medicinal compounds produced by Ephedra sinica and Catha edulis. Two commonly used members of this class of compounds include the cough suppressant (1S-2S)-pseudoephedrine, and the stimulant (1R-2S)-ephedrine. These secondary metabolites are produced in planta through a L-phenylalanine derived multi-step pathway. Despite the importance of this biosynthetic pathway, only one enzyme in the pathway has been characterized at the molecular level. Recently, two new transcriptomes have been created for E. sinica and C. edulis with the hopes of facilitating future gene discovery in this untapped pathway. In this investigation, I outlined an efficient transcriptomics based approach to potential gene candidate selection for all putative stages of the amphetamine analog biosynthetic pathway. This investigation also describes a complete approach to molecular cloning, protein expression, and assaying of gene candidates, resulting in the discovery of a key biosynthetic enzyme involved in amphetamine analog biosynthesis in E. sinica.

description: Breast cancer (BC) and diabetes mellitus are the most relevant risk and development factors in modern oncology. The paper presents the analysis of the molecular breast cancer subtypes in patients with diabetes mellitus (DM) and without diabetes. In our material it was found that patients with diabetes there is a predominance in the frequency of luminal subtypes, and less receptioni. As a result, these factors, combined with early and timely diagnosis, can increase the observed 5-year survival rate in patients with DM .But in the presence of DM with metabolic disorders, the survival rate is significantly lower. As a result, these factors, combined with early and timely diagnosis, can increase the observed 5-year survival rate in this category of patients. But in the presence of DM with metabolic disorders, the survival rate is significantly lower. There is a question of conducting opportunistic screening.

description: Using a three-dimensional mean-field model we study one-dimensional dipolar Bose-Einstein condensate (BEC) solitons on a weak two-dimensional (2D) square and triangular optical lattice (OL) potentials placed perpendicular to the polarization direction. The stabilization against collapse and expansion of these solitons for a fixed dipolar interaction and a fixed number of atoms is possible for short-range atomic interaction lying between two critical limits. The solitons collapse below the lower limit and escapes to infinity above the upper limit. One can also stabilize identical tiny BEC solitons arranged on the 2D square OL sites forming a stable 2D array of interacting droplets when the OL sites are filled with a filling factor of 1/2 or less. Such an array is unstable when the filling factor is made more than 1/2 by occupying two adjacent sites of OL. These stable 2D arrays of dipolar superfluid BEC solitons are quite similar to the recently studied dipolar Mott insulator states on 2D lattice in the Bose-Hubbard model by Capogrosso-Sansone et al. [B. Capogrosso-Sansone, C. Trefzger, M. Lewenstein, P. Zoller, G. Pupillo, Phys. Rev. Lett. 104 (2010) 125301].

description: The atomic bombings of Hiroshima and Nagasaki in August 1945 made Wallace H. Coulter abruptly comprehend the critical need for rapid and accurate blood-cell counts in providing care for victims of radiation exposure. This thesis documents the unwritten story of his journey from that comprehension through his invention and implementation of the Coulter Principle, its commercialization in the first widely available automated blood-cell counter, and elaboration of that ground-breaking counter into increasingly sophisticated instrumentation for analysis not only of blood cells, but of particles involved in many other scientific disciplines. International cold-war politics and the burgeoning of increasingly powerful nuclear weapons were important motivations for him throughout the period here considered; these are summarized as context for his developmental activities.

The Coulter Principle states that if a suspension of blood cells is passed through a small restriction simultaneously with an electric current, the cells will modulate the current, so enabling them to be counted and sized. Today, hematology analyzers based on the Coulter Principle daily process blood samples from many more patients than the number of casualties from the Hiroshima and Nagasaki bombings.

In closing, significant recognitions of Coulter’s contributions are summarized.

description: The photoelectron properties of DNA and RNA bases are studied using many-body perturbation theory within the GW approximation, together with a recently developed Lanczos-chain approach. Calculated vertical ionization potentials, electron affinities, and total density of states are in good agreement with experimental values and photoemission spectra. The convergence benchmark demonstrates the importance of using an optimal polarizability basis in the GW calculations. A detailed analysis of the role of exchange and correlation in both many-body and density-functional theory calculations shows that while self-energy corrections are strongly orbital-dependent, they nevertheless remain almost constant for states that share the same bonding character. Finally, we report on the inverse lifetimes of DNA and RNA bases, that are found to depend linearly on quasi-particle energies for all deep valence states. In general, our G0W0-Lanczos approach provides an efficient yet accurate and fully converged description of quasiparticle properties of five DNA and RNA bases.

description: Technological advances enabled horizontal drilling to expose deeper and longer horizontal lateral sections, thereby maximizing producing zones in reservoirs. The use of Coiled Tubing (CT) to perform different types of well intervention operations is limited by the maximum depth in the horizontal section. One of the most effective remedies is the application of downhole vibration. This thesis proposes a method to describe the effect of vibrations to improve load transfer for a CT with a straight, a sinusoidally buckled and a helically buckled configuration. In order to capture the effect of vibration on the reduction of friction, the concept of apparent friction factor is introduced for all three types of section. The proposed approach is validated against published experimental data, for both the non-vibrating and the vibrating cases. Full wellbore axial force transfer and slack-off weight models are developed to simulate the effect of downhole vibration to enhance CT reach.

description: Methane biofiltration is a cost-effective technology that reduces the effect of greenhouse gases in the atmosphere through bacterial conversion of methane into carbon dioxide without producing harmful by-products. It is very important that media in which the bacteria live possesses certain characteristics that allows them to grow properly. Compost has been widely used, but it has disadvantages such as instability and compaction issues. The aim of this work was to investigate the performance of flax straw, wood shavings, and lava rock (with and without nutrient addition) used in a mixture along with compost looking to provide better conditions for methanotrophs to thrive and achieve high methane oxidation rates with little degradation from the media. Through laboratory column experiments we found the best material to be the compost:wood shavings mixture in a 30:70 ratio at 70% of FC, with 89% removal efficiency.
