Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: We propose a scheme of strong and tunable coupling between a superconducting phase qubit and nanomechanical torsional resonator. In our scheme the torsional resonator directly modulates the largest energy scale (the Josephson coupling energy) of the phase qubit, and the coupling strength is very large. We analyze the quantum correlation effects in the torsional resonator as a result of the strong coupling to the phase qubit.

description: We describe and compare two methods for the group sequential design of two-arm experiments with Poisson distributed data, which are based on a normal approximation and exact calculations respectively. A framework to determine near-optimal stopping boundaries is also presented. Using this framework, for a considered example, we demonstrate that a group sequential design could reduce the expected sample size under the null hypothesis by as much as 44% compared to a fixed sample approach. We conclude with a discussion of the advantages and disadvantages of the two presented procedures.

description: Dependent censoring is common in many medical studies, especially when there are multiple occurrences of the event of interest. Ghosh and Lin (2003) and Hsieh, Ding and Wang (2011) proposed estimation procedures using an artificial censoring technique. However, if covariates are not bounded, then these methods can cause excessive artificial censoring. In this paper, we propose estimation procedures for the treatment effect based on a novel application of propensity scores. Simulation studies show that the proposed method provides good finite-sample properties. The techniques are illustrated with an application to an HIV dataset.

description: We present results on the relationships between persistent currents and the known conservation laws in the classical Toda ring. We also show that perturbing the integrability leads to a decay of the currents at long times, with a time scale that is determined by the perturbing parameter. We summarize several known results concerning the Toda ring in 1-dimension, and present new results relating to the frequency, average kinetic and potential energy, and mean square displacement in the cnoidal waves, as functions of the wave vector and a parameter that determines the non linearity.

description: Electrochemical methods offer great promise in meeting the demand for user-friendly on-site devices for monitoring important parameters. The food industry often runs own lab procedures, for example, for mycotoxin analysis, but it is a major goal to simplify analysis, linking analytical methods with smart technologies. Enzyme-linked immunosorbent assays, with photometric detection of 3,3’,5,5’-tetramethylbenzidine (TMB), form a good basis for sensitive detection. To provide a straightforward approach for the miniaturization of the detection step, we have studied the pitfalls of the electrochemical TMB detection. By cyclic voltammetry it was found that the TMB electrochemistry is strongly dependent on the pH and the electrode material. A stable electrode response to TMB could be achieved at pH 1 on gold electrodes. We created a smartphone-based, electrochemical, immunomagnetic assay for the detection of ochratoxin A in real samples, providing a solid basis for sensing of further analytes.
Examining the relationship between children's theory of mind and social-emotional functioning
Creators: name: Haddock, Taeh Bonn
Publisher: name: University of British Columbia
Year: 2025

description: Individual differences in mental state understanding, or ‘theory of mind’, predict individual differences in social-emotional functioning. Despite the importance of theory of mind and social-emotional functioning, the majority of research has used measures that tap only one or two aspects of mental state understanding (e.g., false beliefs) and social-emotional functioning (e.g., prosocial behaviour). My dissertation expands on earlier work by including multi-faceted measures allowing me to: (a) test whether theory of mind as a whole predicts social-emotional functioning, (b) examine which facet of theory of mind is most predictive, and (c) compare the magnitude of the relationship between theory of mind and different facets of social-emotional functioning. Across 2 studies (n = 768 children aged 3 to 12) I found that theory of mind as a global construct (measured by the Children’s Social Understanding Scale; CSUS) predicts multiple facets of children’s social-emotional functioning (measured by the Strengths and Difficulties Questionnaire in both studies and the Social Skills Improvement System in Study 2). In Study 2 parents also completed a self-report measure of their theory of mind (i.e., Empathy Quotient) revealing that maternal theory of mind was a predictor of their child’s social-emotional functioning and mental state understanding, with the relationship to children’s social-emotional functioning primarily explained by children’s mental state understanding. My work made three additional contributions: (1) identifying the factor structure underlying mental state understanding in the CSUS, (2) examining how each factor predicts children’s social-emotional functioning, and (3) examining how parents’ theory of mind predicts each factor of their child’s theory of mind. Exploratory Factor Analysis revealed a two-factor structure that appears to represent ‘basic’ versus ‘complex’ mental state understanding. Analyses revealed that complex mental state understanding was most predictive of children’s social-emotional functioning, and maternal theory of mind was most predictive of children’s complex mental state understanding. My work advances our understanding of the nature of the relationships between children’s theory of mind and social-emotional functioning by providing a more comprehensive analyses of these relationships, and highlighting that complex mental state understanding is of particular importance to children’s social-emotional wellbeing.
Fragmentation behavior of EDTA complexes under different activation conditions

description: Ethylenediaminetetraacetic acid (EDTA) is an aminopolycarboxylic acid and complexation agent that is able to bind a large variety of metals. The formation of highly stable metal-EDTA complexes is generally very quick. This has led to the use of EDTA in a variety of applications, including food, medical, and household applications. In the current study, we have investigated the fragmentation behavior of EDTA and various metal complexes under collision-induced dissociation (CID), infrared-multiphoton dissociation (IRMPD), and higher-energy collisional dissociation (HCD) activation conditions. Both, positive and negative mode electrospray ionization (ESI) were applied. The metals used to complex with EDTA ranged from alkaline earth metals, such as sodium and cesium, via calcium, nickel, zinc, aluminum, copper, iron, and indium to yttrium and several lanthanides. Furthermore, the protonated and deprotonated species of EDTA, as well as disodium and trisodium species, have been subjected to fragmentation. The results show that characteristic fragmentations were obtained for EDTA and the metal complexes under the investigated conditions. The use of an ion cyclotron resonance (ICR) and an Orbitrap mass spectrometer, as high resolution-accurate mass instruments, allowed the assignment of elemental compositions undoubtedly for the vast majority of fragments. Certain trends were observed that trend correlated with the size of the metal and the location within the periodic table.

description: For a number field K with absolute Galois group G_K, we consider the action of G_K on the infinite tree of preimages of a point in K under a degree-two rational function phi, with particular attention to the case when phi commutes with a non-trivial Mobius transfomation. In a sense this is a dynamical systems analogue to the l-adic Galois representation attached to an elliptic curve, with particular attention to the CM case. Using a result about the discriminants of numerators of iterates of phi, we give a criterion for the image of the action to be as large as possible. This criterion is in terms of the arithmetic of the forward orbits of the two critical points of phi. In the case where phi commutes with a non-trivial Mobius transfomation, there is in effect only one critical orbit, and we give a modified version of our maximality criterion. We prove a Serre-type finite-index result in many cases of this latter setting.

description: In this thesis, a web application which is capable of calculating the energy consumption of a fleet of electric vehicles is developed. This web app is capable of gathering data for each trip that the EVs complete and calculate the distance that they traverse in each trip through Google Maps, this will allow our web application to process that data and predict with accuracy the load on the grid of either an individual with his EV or a fleet of EVs. In order to simulate a realistic behavior of a fleet of EVs we have used the data from the National Household Travel Survey (https://nhts.ornl.gov/).  With this data base as a basis we have the probability density for the usage of EVs on their departure times, type of trip (work, pleasure etc.) as well as their idle time.

description: On November 5, 1990, Congress passed the Coastal Zone Act Reauthorization Amendments (CZARA), adding important nonpoint source water pollution requirements to the provisions of the Coastal Zone Management Act of 1972. The potential significance of the agricultural nonpoint source requirements in CZARA is twofold. First, it is the first federally mandated program requiring specific measures to deal with agricultural nonpoint sources. Second, it is being viewed as a model for stronger programs to deal with nonpoint source pollution. Based on an analysis of management measures included in EPA's national guidance and coastal farm profiles, annual costs of the proposed measures are typically less than $5,000 per farm for most farm sizes. Exceptions are grazing management measures on larger farm sizes in the West, for which costs range up to $75,539, and combined measures on larger dairy farms in all regions, for which costs range from $9,606 to $26,824. While coastal zone agriculture is quite different in both physical and economic terms from noncoastal agriculture, the general level of costs, impact on incomes, and relative differences between types of farms and size classes provide insight for a more comprehensive national program of nonpoint source control measures.

description: Atrial fibrillation (AF) is the most common diagnosed cardiac arrhythmia worldwide and contributes to one in four cerebrovascular accidents (also called strokes) in people over the age of 40 years old in Canada. The purpose of this pilot study was to assess the efficacy of a credible, educational website, used to educate people about their AF with the aim of increasing their AF knowledge and self-efficacy. A mixed-methods design was used to collect both quantitative and qualitative data. Participants were initially recruited through dedicated cardiac rehabilitation clinics; due to the COVID-19 pandemic, recruitment was changed to online using social media (Instagram, Facebook) and by word-of-mouth. A total of nine participants completed the educational website intervention for a total of four weeks, and three participated in the follow-up semi-structured interview. Participants baseline demographics were collected following consent; AF knowledge and self-efficacy measurements were collected pre- and post-website intervention. AF knowledge was measured using the Knowledge about Atrial Fibrillation Survey and self-efficacy was measured using the Chronic Disease Self-Efficacy Scale. While using the website participants were given alias logins to allow for confidentiality to be maintained and data on website usage was collected using Google Analytics. The results of the AF knowledge and self-efficacy scores were compared using paired t-tests and showed no statistical significance between before and after scores, likely due to the small sample size. Participants used the website in various ways, from low to high website usage, which, did not have an impact on AF knowledge or self-efficacy scores. Participant’s semi-structured interviews gave light to the value participants saw in an AF website, the quality of the information on the website and recommendations for change to the website. This study illustrates that there is a place in AF education for a web-based educational tool. Researchers, patient educators and practitioners should use this study to guide AF patient education.
New length operator for loop quantum gravity

description: An alternative expression for the length operator in loop quantum gravity is presented. The operator is background independent, symmetric, positive semidefinite, and well defined on the kinematical Hilbert space. The expression for the regularized length operator can moreover be understood both from a simple geometrical perspective as the average of a formula relating the length to area, volume and flux operators, and also consistently as the result of direct substitution of the densitized triad operator with the functional derivative operator into the regularized expression of the length. Both these derivations are discussed, and the origin of an undetermined overall factor in each case is also elucidated.

3D Classification of Cold-Water Coral Reefs: A Comparison of Classification Techniques for 3D Reconstructions of Cold-Water Coral Reefs and Seabed

description: Submarine canyons and cold-water corals (CWC) are key components of ocean ecosystems due to their complex geomorphology and their role in nutrient supply dynamics. As three-dimensional structural habitats, there is a need for robust and accessible technologies to enable more accurate representations and assessments of these environments. The use of Remotely Operated Vehicles (ROV) and Structure-from-Motion (SfM) photogrammetry combined represent an effective and non-destructive method that yields high-resolution reconstructions of deep-sea environments such as CWC habitats and submarine canyons. This research focused on the application of underwater photogrammetry to improve seabed classification techniques on the Porcupine Bank Canyon (PBC), located at approx. 300 km offshore Ireland. We have developed a classification scheme in different habitats within the canyon which will aid the understanding of the main environmental patterns of CWC distribution within the canyon. Three binary classification methods were applied, namely: Multiscale geometrical classification (MGC), Colour and Geometrical classification (CGC) and Object-based classification (OBIA) for the baseline method. The application of these methodologies brought novelty to the study because, although these approaches are well stablished in other fields such as terrestrial image analysis, they had not yet been applied to marine environments. We analysed the classification accuracy results, overall performance and the potential loss of information when using 2D and 3D data. Our results showed that 3D the MGC method outperforms the CGC methods. However, each method has advantages for specific applications pertinent to the wider marine scientific community. Results suggest that advancing from commonly employed 2D image analysis techniques to 3D photogrammetry classification methods is advantageous and may provide a more realistic representation of CWC habitats.

description: We consider particle transport under the influence of time-varying driving forces, where fluctuation relations connect the statistics of pairs of time reversed evolutions of physical observables. In many "mesoscopic" transport processes, the effective many-particle dynamics is dominantly classical, while the microscopic rates governing particle motion are of quantum-mechanical origin. We here employ the stochastic path integral approach as an optimal tool to probe the fluctuation statistics in such applications. Describing the classical limit of the Keldysh quantum nonequilibrium field theory, the stochastic path integral encapsulates the quantum origin of microscopic particle exchange rates. Dynamically, it is equivalent to a transport master equation which is a formalism general enough to describe many applications of practical interest. We apply the stochastic path integral to derive general functional fluctuation relations for current flow induced by time-varying forces. We show that the successive measurement processes implied by this setup do not put the derivation of quantum fluctuation relations in jeopardy. While in many cases the fluctuation relation for a full time-dependent current profile may contain excessive information, we formulate a number of reduced relations, and demonstrate their application to mesoscopic transport. Examples include the distribution of transmitted charge, where we show that the derivation of a fluctuation relation requires the combined monitoring of the statistics of charge and work.

description: Excerpt from the report Summary: Corn, soybeans, and sorghum make up about a third of all U.S. crop receipts. Corn, soybeans, and sorghum also represent major crops produced by specialized feed grain farms. More than 80 percent of commercial feed grain farmers, defined as those with annual sales of $50,000 or more and for whom farming was their primary occupation, realized positive incomes over the 1987-91 period. The profitability of commercial feed grain farms, measured by return on assets, exceeded that of commercial producers of small grains (oats, wheat, barley), beef, and dairy, matched that of commercial hog producers, and was less than that of commercial farms producing cotton and rice over the 1987-91 period. Nearly three-fourths of the commercial feed grain farms are in the Midwest, and they produce 70 percent of U.S. corn, 78 percent of U.S. soybeans, and 33 percent of U.S. sorghum.

description: Let q be an odd positive integer and P \in F2[z] be of order q and such that P(0) = 1. We denote by A = A(P) the unique set of positive integers satisfying \sum_{n=0}^\infty p(A, n) z^n \equiv P(z) (mod 2), where p(A,n) is the number of partitions of n with parts in A. In [5], it is proved that if A(P, x) is the counting function of the set A(P) then A(P, x) << x(log x)^{-r/ϕ(q)}, where r is the order of 2 modulo q and ϕis Euler's function. In this paper, we improve on the constant c=c(q) for which A(P,x) << x(log x)^{-c}.

description: Fruit and vegetable trade between the United States and Mexico grew tremendously between 1970 and 1992. Mexico was the major source of U.S. imports of winter and cool-weather vegetables and citrus fruit. U.S. exports of fruit and vegetables to Mexico also began to grow, especially in the last few years of the period. U.S. horticultural products, however, were still minor export commodities in 1992, compared with grains and animal products. The data in this report are useful for understanding the trade situation between the two countries.

description: We present Herschel observations of the water molecule in the massive star-forming region W3 IRS5. The o-H17O 110-101, p-H18O 111-000, p-H2O 22 202-111, p-H2O 111-000, o-H2O 221-212, and o-H2O 212-101 lines, covering a frequency range from 552 up to 1669 GHz, have been detected at high spectral resolution with HIFI. The water lines in W3 IRS5 show well-defined high-velocity wings that indicate a clear contribution by outflows. Moreover, the systematically blue-shifted absorption in the H2O lines suggests expansion, presumably driven by the outflow. No infall signatures are detected. The p-H2O 111-000 and o-H2O 212-101 lines show absorption from the cold material (T ~ 10 K) in which the high-mass protostellar envelope is embedded. One-dimensional radiative transfer models are used to estimate water abundances and to further study the kinematics of the region. We show that the emission in the rare isotopologues comes directly from the inner parts of the envelope (T > 100 K) where water ices in the dust mantles evaporate and the gas-phase abundance increases. The resulting jump in the water abundance (with a constant inner abundance of 10^{-4}) is needed to reproduce the o-H17O 110-101 and p-H18O 111-000 spectra in our models. We estimate water abundances of 10^{-8} to 10^{-9} in the outer parts of the envelope (T < 100 K). The possibility of two protostellar objects contributing to the emission is discussed.

description: Wide angle and deep surveys, regardless of their primary purpose, always sample a large number of stars in the Galaxy and in its satellite system. We here make a forecast of the expected stellar sample resulting from the Dark Energy Survey and the perspectives that it will open for studies of Galactic structure and resolved stellar populations in general. An estimated 1.2x10^8 stars will be sampled in DES grizY filters. This roughly corresponds to 20% of all DES sources. Most of these stars belong to the stellar thick disk and halo of the Galaxy. DES will probe low-mass stellar and sub-stellar objects at depths from 3 to 8 times larger than SDSS. The faint end of the main-sequence will be densely sampled beyond 10 kpc. The slope of the low mass end of the stellar IMF will be constrained to within a few hundredth dex, even in the thick disk and halo. In the sub-stellar mass regime, the IMF slope will be potentially constrained to within dlog ϕ(m) / dlog m ~ 0.1$. About 3x10^4 brown dwarf and at least 7.6x10^5 white dwarf candidates will be selected, the latter embedded into the thick disk and halo. The stellar halo flattening will also be constrained to within a few percent. DES will probe the main sequence of new Milky Way satellites and halo clusters for distances out to ~ 120 kpc, therefore yielding stellar surface density contrasts 1.6-1.7 times larger than those attainable with SDSS. It will also allow detection of these objects in the far reaches of the stellar halo, substantially increasing the number and quality of probes to the Galactic potential. Combined with northern samples, such as the SDSS, the DES stellar sample will yield constraints on the structure and stellar populations of Galactic components in unprecedented detail. In particular, the combined sample from both hemispheres will allow detailed studies of halo and thick disk asymmetries and triaxiality.

description: It is generally acknowledged among scholars in the field of Late Antiquity that relations between the Roman and Iranian Empires reached its climax in the early fifth century. Countless sources report a variety of co-operative events depicting positive dealings between the Iranian shah Yazdgird and the Roman emperors Arcadius and Theodosius II. On the other hand, there exist just as many accounts that Yazdgird persecuted the Christians of his realm towards the end of his life. We are thus left with opposing narratives about the Iranian monarch, and no clarification about what truly transpired. This thesis seeks to clarify the ambiguities surrounding Yazdgird‟s reign. In order to achieve this goal, the events and circumstances that led to the apogee of Roman-Iranian relations is first retraced. An examination of potential sources of tension follows this, with the thesis culminating in the final chapter directly engaging the question of whether Yazdgird persecuted the Christians of his realm or not. The focus of this study is not solely to answer the question outlined above, but also to analyze and revise the entire topic utilizing a more holistic approach. Recent scholarship on East Syrian Christianity and the Sasanian Empire aided in providing alternative perspectives to the traditionally unilateral Roman views of the outlined issues. These different viewpoints in turn helped shape new interpretations and conclusions concerning the apogee and decline of RomanoIranian relations in the early fifth century.
Carbon nitride photocatalysis : an investigation on the influence of morphology
Creators: name: Mitchell, Emma Louise
Publisher: name: University of British Columbia
Year: 2021

description: The development of reliable renewable energy sources is imperative for a sustainable future. To address this issue, the development of suitable photocatalysts that can produce clean renewable energy at a sustainable cost has become a rapidly expanding research area. Carbon nitride (CNx), an organic semiconductor, is a promising candidate for this role due to its easy synthesis, high stability and tunability. The potential of CNx has been highlighted with reports of highly efficient photocatalytic hydrogen production (quantum yields >50%) under sacrificial conditions. However, the efficiency remains limited for sustainable overall water splitting. To improve the efficiencies, modification of the material’s morphology has been pursued. However, research on the relationship between CNx morphology and photocatalytic efficiency has been inconclusive. Positive correlations as well as variances between CNx photocatalytic activity and surface area have been previously identified. To build a clear relationship between structure-photophysics-activity, different morphologies were prepared and studied. These were mesoporous (meso), macroporous (macro), SBA, and hollow sphere CNx. Progress towards synthesizing hollow sphere CNx was achieved, however, a reproducible synthesis has yet to be accomplished. The trend in photocatalytic hydrogen production of the successfully synthesized materials was as follows meso CNx, < Bulk CNx < SBA CNx < macro CNx. There were differences in the structural and electronic characterization, however, the trends were not consistent with the observed photocatalytic activity. Using Transient Absorption Spectroscopy (TAS), the normalized decay kinetics were found to be similar between all morphologies, indicating that changes in trap state distribution or electronic structure likely do not greatly impact the photocatalytic hydrogen evolution. A direct positive correlation between surface area and photocatalytic activity was observed. The largest increase in surface area of a modified morphology compared to bulk CNx was in macro CNx which had a surface area 1.7-fold larger and an apparent quantum yield (AQY) of 3.6%. These smaller surface area changes observed herein could indicate the morphological modifications do not extend to the nanostructure of the material. Extending CNx modification to the nanostructure of the material could be the key to induce more significant electronic or structural changes which affect the photocatalytic activity.
