description: TianQin (TQ) project plans to deploy three satellites in space around the Earth to measure the displacement change of test masses caused by gravitational waves via laser interferometry. The requirement of the acceleration noise of the test mass is on the order of $10^{-15}~\,{\rm m}\,{\rm s}^{-2}\,{\rm Hz}^{-1/2}$ in the sensitive frequency range of TQ, %the extremely precise acceleration measurement requirements make it necessary to investigate acceleration noise due to space magnetic fields. which is so stringent that the acceleration noise caused by the interaction of the space magnetic field with the test mass needs to be investigated. In this work, by using the Tsyganenko model, a data-based empirical space magnetic field model, we obtain the magnetic field distribution around TQ's orbit spanning two solar cycles in 23 years from 1998 to 2020. With the obtained space magnetic field, we derive the distribution and amplitude spectral densities (ASDs) of the acceleration noise of TQ in 23 years. Our results reveal that the average values of the ratio of the acceleration noise cauesd by the space magnetic field to the requirements of TQ at 1 mHz ($R_{\rm 1mHz}$) and 6 mHz ($R_{\rm 6mHz}$) are 0.123$\pm$0.052 and 0.027$\pm$0.013, respectively. The occurence probabilities of $R_{\rm 1mHz}>0.2$ and $>0.3$ are only 7.9% and 1.2%, respectively, and $R_{\rm 6mHz}$ never exceeds 0.2.

description: Phonon-photon interactions mediated by optical radiation pressure are powerful tools for quantum information transduction, for example between a quantum system used by a quantum computer or quantum memory and a quantum system used by a quantum communication network. Cavity optomechanics enhances photon-phonon interactions by co-localization of optical fields and mechanical resonances. The implementation of phononic localization in the majority of cavity optomechanical devices relies on creating suspended devices whose substrate has been selectively removed. However, this approach hinders integration with other quantum computing and communication components. As an alternative, we have developed optomechenical cavities based on a gallium phosphide-on-diamond platform with no substrate removal. This new platform takes advantage of the high speed of sound in diamond to confine phonons via total internal acoustic reflection. We have designed a device that is predicted to allow an optomechanical photon-phonon coupling rate g0~110 kHz between photons in its cavity mode and phonons in its fundamental mechanical breathing mode. Our devices also have a great potential as an optomechanical interface for coupling electron spins of defect centers in diamond crystal lattice to telecommunication wavelength photons via optomechanically induced strain.

description: This paper presents a reconfigurable intelligent sensing surface (RISS) that combines passive and active elements to achieve simultaneous reflection and direction of arrival (DOA) estimation tasks. By utilizing DOA information from the RISS instead of conventional channel estimation, the pilot overhead is reduced and the RISS becomes independent of the hybrid access point (HAP), enabling efficient operation. Specifically, the RISS autonomously estimates the DOA of uplink signals from single-antenna users and reflects them using the HAP's slowly varying DOA information. During downlink transmission, it updates the HAP's DOA information and designs the reflection phase of energy signals based on the latest user DOA information. The paper includes a comprehensive performance analysis, covering system design, protocol details, receiving performance, and RISS deployment suggestions. We derive a closed-form expression to analyze system performance under DOA errors, and calculate the statistical distribution of user received energy using the moment-matching technique. We provide a recommended transmit power to meet a specified outage probability and energy threshold. Numerical results demonstrate that the proposed system outperforms the conventional counterpart by 2.3 dB and 4.7 dB for Rician factors $κ_h=κ_G=1$ and $κ_h=κ_G=10$, respectively.
Signatures of Rashba spin-orbit interaction in the superconducting proximity effect in helical Luttinger liquids

description: We consider the superconducting proximity effect in a helical Luttinger liquid at the edge of a 2D topological insulator, and derive the low-energy Hamiltonian for an edge state tunnel-coupled to a s-wave superconductor. In addition to correlations between the left and right moving modes, the coupling can induce them inside a single mode, as the spin axis of the edge modes is not necessarily constant. This can be induced controllably in HgTe/CdTe quantum wells via the Rashba spin-orbit coupling, and is a consequence of the 2D nature of the edge state wave function. The distinction of these two features in the proximity effect is also vital for the use of such helical modes in order to split Cooper-pairs. We discuss the consequent transport signatures, and point out a long-ranged feature in a dc conductance measurement that can be used to distinguish the two types of correlations present and to determine the magnitude of the Rashba interaction.

description: We present a fast method for reconstructing Differential Emission Measures (DEMs) using solar coronal data. On average, the method computes over 1000 DEMs per second for a sample active region observed by the Atmospheric Imaging Assembly (AIA) on the Solar Dynamics Observatory (SDO), and achieves reduced chi-squared of order unity with no negative emission in all but a few test cases. The high performance of this method is especially relevant in the context of AIA, which images of order one million solar pixels per second. This paper describes the method, analyzes its fidelity, compares its performance and results with other DEM methods, and applies it to an active region and loop observed by AIA and by the Extreme-ultraviolet Imaging Spectrometer (EIS) on Hinode.

description: The extensive and growing use of the Internet over the past decade has provided businesses with vast opportunities to learn more about their online customers. These data might be quite beneficial for organizations operating in a variety of areas. However, internet users are concerned about the privacy of their online information since their personal information is gathered and shared without their consent. Different internet marketplaces are impacted by these privacy problems. We examine the impact of online privacy concerns on processes and decisions in three distinct market settings. First, we investigate how websites disclose personal information about their users with third parties and what drives them to conceal such sharing. Our data demonstrate that obfuscation of information sharing is a viable strategy for websites. Second, we propose an incentive-compatible compensation mechanism and novel sampling methods for a platform to get users' permission to share their data on a personal data marketplace. We analyze the tradeoffs between sample size, bias, cost, and privacy, as well as the performance of the proposed methods in comparison to benchmarks. Third, we examine a market for advertising in which individuals sell their attention to advertisers through a platform intermediary. We study how consumers' lack of awareness about the value of their attention influences their decision-making.

description: We introduce a fast Fourier transform on regular d-dimensional lattices. We investigate properties of congruence class representants, i.e. their ordering, to classify directions and derive a Cooley-Tukey-Algorithm. Despite the fast Fourier techniques itself, there is also the advantage of this transform to be parallelized efficiently, yielding faster versions than the one-dimensional Fourier transform. These properties of the lattice can further be used to perform a fast multivariate wavelet decomposition, where the wavelets are given as trigonometric polynomials. Furthermore the preferred directions of the decomposition itself can be characterised.

description: Prader-Willi syndrome is a genetic disorder that causes insatiable hunger and overeating. It poses both significant health risks and complex social challenges for families. The experiences of mothers caring for a child with Prader Willi syndrome and managing the hyperphagia and anxiety are not well known. Researchers have studied the biological make up of Prader Willi syndrome but few have explored mothers’ experiences in managing the physical and mental health issues of caring for a child with hyperphagia, anxiety, and insatiation. This study is a narrative inquiry into the experiences of four mothers caring for their children with Prader Willi syndrome. Narrative inquiry is the study of experience using storied accounts and attends to the dimensions of temporality, place, and sociality. Four narrative accounts were co-composed with participants and highlight the complex political and social landscapes for families. The narrative accounts revealed two narrative threads, engaging in (extra)ordinary care practices, and navigating tensions called forth by coherent and incoherent stories. Recommendations for practice, policy, and theory are also presented after inquiring into mothers’ experiences.
Follow the money : philanthropy in China - who's giving, to whom, and why?
Creators: name: Tipton, Benjamin A. E.
Publisher: name: University of British Columbia
Year: 2012

description: Surveys conducted in China suggest that the Chinese are not generous with their resources - their money, time, or help. However, there is much evidence to the contrary, when viewing the data with different lenses. Giving is increasing and the growth of civil society is accelerating. This thesis examines the individual philanthropic giving that occurs in the Peoples Republic of China (PRC). By “following the money” this study fills in a gap in available academic literature, and investigates the influences on giving behavior and the particular giving characteristics of the Chinese. This paper examines the social, cultural, economic and political factors; the regulatory framework - such as laws and regulations; and, other developments occurring around the PRC by local authorities responding to civil society crises in transparency and reporting requirements. The research strategies employed throughout are: (1) quantitative surveys, (2) qualitative ethnographic research methods, and (3) field research conducted during 2011. By using recent events such as the Sichuan earthquake in 2008 - when Chinese individuals donated record amounts of resources - and the public trust crisis of 2011, this study reflects on the current issues influencing giving. The qualitative research provides an in-depth look at the historical influences on giving. Data have been collected from government, civil society, and business reports; international and domestic surveys; media reports; PRC statutes and regulations. Some view Chinese as lacking generosity, but perspective on this issue is particularly important when considering the cultural, economic and political differences between people groups compared. This thesis explores the giving that occurs in the PRC and the influences on that giving - which we call - individual philanthropic giving with Chinese characteristics. By following the money, this thesis provides a comprehensive perspective and interpretation of the giving that currently occurs in the PRC and how it differs from giving in other countries around the world.

description: The Magellanic Clouds are the most massive and closest satellite galaxies of the Milky Way, with stars covering ages from a few Myr up to 13 Gyr. This makes them important for validating integrated light methods to study stellar populations and star-formation processes, which can be applied to more distant galaxies. We characterized a set of stellar clusters in the Small Magellanic Cloud (SMC), using the $\textit{Southern Photometric Local Universe Survey}$. This is the first age (metallicity) determination for 11 (65) clusters of this sample. Through its 7 narrow bands, centered on important spectral features, and 5 broad bands, we can retrieve detailed information about stellar populations. We obtained ages and metallicities for all stellar clusters using the Bayesian spectral energy distribution fitting code $\texttt{BAGPIPES}$. With a sample of clusters in the color range $-0.20 < r-z < +0.35$, for which our determined parameters are most reliable, we modeled the age-metallicity relation of SMC. At any given age, the metallicities of SMC clusters are lower than those of both the Gaia Sausage-Enceladus disrupted dwarf galaxy and the Milky Way. In comparison with literature values, differences are $Δ$log(age)$\approx0.31$ and $Δ$[Fe/H]$\approx0.41$, which is comparable to low-resolution spectroscopy of individual stars. Finally, we confirm a previously known gradient, with younger clusters in the center and older ones preferentially located in the outermost regions. On the other hand, we found no evidence of a significant metallicity gradient.

description: We present a theory of magnetotransport through a system of two coupled electronic orbitals, where the electron spin interacts with a (large) local magnetic moment via an exchange interaction. For the physical realization of such a set-up we have in mind, for example, semiconductor quantum dots coupled to an ensemble of nuclear spins in the host material or molecular orbitals coupled to a local magnetic moment. Using a semiclassical approximation, we derive a set of Ehrenfest equations of motion for the electron density matrix and the mean value of the external spin (Landau equations): Due to the spin coupling they turn out to be nonlinear and, importantly, also coherences between electron states with different spin directions need to be considered. The electronic spin-polarized leads are implemented in form of a Lindblad-type dissipator in the infinite bias limit. We have solved this involved dynamical system numerically for various isotropic and anisotropic coupling schemes. For isotropic spin coupling and spin-polarized leads we study the effect of current-induced magnetization of the attached spin and compare this with a single quantum dot set-up. We further demonstrate that an anisotropic coupling can lead to a rich variety of parametric oscillations in the average current reflecting the complicated interplay between the Larmor precession of the external spin and the dissipative coherent dynamics of the electron spin.

description: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are a rare group of tumors.
Temozolomide (TMZ) alone or combined with capecitabine (CAPTEM) has been considered as an effective treatment in this setting of tumors.
O6-Methylguanine-DNA methyltransferase (MGMT) status has been suggested to be predictive of response in NETs treated with TMZ-based therapy. MGMT status can be evaluated through MGMT promoter methylation, a mechanism of MGMT inactivation.
In this study, we aimed to evaluate retrospectively the predictive and prognostic value of MGMT promoter methylation in patients with GEP-NETs treated with CAPTEM in our institution.

A metabolomic- and transcriptomic-level investigation of ant brains infected with the lancet liver fluke Dicrocoelium dendriticum

description: Parasites often manipulate host phenotypes to facilitate their own transmission. Wood ants, Formica aserva, infected with larvae of the lancet liver fluke, Dicrocoelium dendriticum, leave their nests during the cool hours of the day to ascend and attached to a plant, where they remain overnight, and detach the next morning when temperatures rise returning to their nest. They repeat this bizarre attachment and detachment sequence for the rest of the summer. My thesis seeks to understand the molecular mechanisms that underlie this complex manipulation of host behaviour that is ‘on-then-off’ through metabolomics and transcriptomics approaches. I first characterized changes in the metabolite concentrations in ant brains collected from a site of D. dendriticum emergence in southern Alberta, Canada. Within the laboratory, I recreated the manipulation cycle to mimic pre-attached, attached, and post-attached stages, and sampled infected and uninfected ant brains from each stage. Mean brain concentration of neurotransmitters tyramine and serotonin were reduced in infected ants compared to uninfected during detachment phases by 22% and 17%, respectively. These reductions paralleled a 40% reduction in overall host activity in infected versus uninfected ants during the detachment phase. I then compared the gene expression pattern of brains from infected and uninfected ants at the same samples stages as above. I found that 13,556 genes were differentially expressed, including those involved in environmental sensing and the production of biogenic monoamines. I found genes involved in odorant and vision were downregulated in attached infected ants. Vision genes were upregulated in post-attached infected ants compared to uninfected controls. Genes involved in serotonin synthesis were also downregulated during the post-attached stages in infected ants. These results support that the regulation of biogenic monoamines in the brains of infected ants plays a role in this complex manipulation of host behaviour. Overall, this study helps us better understand how D. dendriticum manipulates their ant host behaviour. My findings show that the mechanisms driving reversible manipulations is more complex than the parasite-induced control of ‘on-then-off’ triggers. In the D. dendriticum-ant system, different mechanisms are involved at different stages of the manipulation.

description: Using holographic duality, we investigate the impact of finite temperature on the instability and splitting patterns of quadruply quantized vortices, providing the first-ever analysis in this context. Through linear stability analysis, we reveal the occurrence of two consecutive dynamical transitions. At a specific low temperature, the dominant unstable mode transitions from the $2$-fold rotational symmetry mode to the $3$-fold one, followed by a transition from the $3$-fold one to the $4$-fold one at a higher temperature. As the temperature is increased, we also observe the $5$ and $6$-fold rotational symmetry unstable modes get excited successively. Employing the full non-linear numerical simulations, we further demonstrate that these two novel dynamical transitions, along with the temperature-induced instabilities for the $5$ and $6$-fold rotational symmetry modes, can be identified by examining the resulting distinct splitting patterns, which offers a promising route for the experimental verification in the cold atom gases.

description: We propose a local renormalization group procedure where length scale is changed in spacetime dependent way. Combining this scheme with an earlier observation that high energy modes in renormalization group play the role of dynamical sources for low energy modes at each scale, we provide a prescription to derive background independent holographic duals for field theories. From a first principle construction, it is shown that the holographic theory dual to a D-dimensional matrix field theory is a (D+1)-dimensional quantum theory of gravity coupled with matter fields of various spins. The gravitational theory has (D+1) first-class constraints which generate local spacetime transformations in the bulk. The (D+1)-dimensional diffeomorphism invariance is a consequence of the freedom to choose different local RG schemes.

description: Cognitive characteristics may leave highly intelligent youth at higher risk of internalizing symptoms, problems in social functioning, or low subjective well-being. This study utilized archival psychoeducational assessment data to compare verbal-fluid intelligence discrepancy with social-emotional self- and parent-report scores in children and adolescents identified as highly intelligent. Results indicated that social stress is associated with verbal-fluid intelligence discrepancy while internalizing symptoms are not. Neither gender nor age was found to influence these relationships significantly. Questionnaire data were collected from a subsample of participants to compare intelligence with measures of self-compassion and meaningfulness in life. When gender and current difficulties (e.g., emotional symptoms, peer problems) were controlled for, intelligence was found to be associated with self-compassion, search for meaning in life, and discrepancy between search for meaning and presence of meaning in life. Female adolescents responded with a significantly greater discrepancy between search for meaning and presence of meaning than did males. These results suggest that cognitive characteristics are associated with social functioning and meaningfulness in highly intelligent youth and that highly intelligent female adolescents may be at particular risk of experiencing a crisis of meaning. Results may help to inform education practice, psychoeducational assessment procedures, and social-emotional intervention for highly intelligent youth.

description: Self-interactions (SIs) are a major problem in density functional approximations and the source of serious divergence from experimental results. Here, we propose to optimize density functional total energies in terms of the effective local potential, under constraints for the effective potential that guarantee it is free from SI errors and consequently asymptotically correct. More specifically, we constrain the Hartree, exchange and correlation potential to be the electrostatic potential of a non-negative effective repulsive density of $N-1$ electrons. In this way, the optimal effective potentials exhibit the correct asymptotic decay, resulting in significantly improved one-electron properties.

description: The Subscription Video-On-Demand (SVOD) market is highly competitive, with companies constantly vying for market share. Inspired by the natural language processing (NLP) technologies that have allowed virtual assistants to flourish, we investigate how NLP could help in film production and film presentation and look for novel ways in which SVOD digital media companies could benefit. In particular, on the film presentation side, we propose a novel context-aware question-answering system that would be integrated with SVOD content to allow viewers of video to ask context-sensitive questions about the film they are watching simply by pausing. On the film production side, we investigate the NLP performance of using natural text as an input in automatic character extraction (also known as co-reference resolution). We present results and prototypes that show that NLP has meaningful use cases, both in film production and film presentation.

description: Due to the evergrowing renewable energy resources and their penetration in the electrical grid, the power system operators face the difficulty of handling such uncertainty while obtaining the result of operation and planning studies in a tractable time. This thesis is focused on developing time aggregation frameworks for compressing renewable energy as well as electricity demand data into a limited number of representative periods from which the complex power system studies can be solved in a reasonable time without reducing the loss of accuracy. First, an overview of different parts of a clustering process is provided. The pros and cons of methods are discussed to help the reader understand the rationale behind the author narrows down the comparative methods in this thesis. A section is also provided to discuss the centroid selection process, which is often an optional step in the clustering process. Yet, it is a crucial step in the time aggregation in the context of power system studies. This thesis tackles the time aggregation challenge by developing a method based on an elastic-based distance that can reflect the volatility of time series data such as wind power while preserving its co-movement with electricity demand. Next, the spatiotemporal factor is taken into account and a method is proposed to handle time aggregation in the presence of several renewable energy resources. Finally, this thesis brings in the concept of stability, and develops a framework that can help with obtaining a set of representative periods that are more stable compared to the existing methods. In all of the aforementioned works, the proposed approach is compared against a set of comparative methods considering both data- and model-based evaluation. Regarding the former, the methods are compared according to their performance in reflecting different characteristics of data. In the latter, the method is evaluated in the context of a power system problem in an electrical network. To better show the impact of our method in preserving shape, energy storage units are added to the network. Different indices are measured to reflect the performance of the proposed approach from different perspectives.

description: We find that in general relativity slow down of the pulsar rotation due to the magnetodipolar radiation is more faster for the strange star with comparison to that for the neutron star of the same mass. Comparison with astrophysical observations on pulsars spindown data may provide an evidence for the strange star existence and, thus, serve as a test for distinguishing it from the neutron star.

Optofluidics for microscopy and sensing

description: Optofluidics describes a relatively new area of research that aims to synergistically combine optics and fluidics technologies. In this work, we examine the application and integration of small fluid volumes into two types of optical devices, yielding improvements in either tunability, flexibility, or cost-effectiveness. First, we explore a simple methodology to dispense and shape water droplets for use as the magnifying element in a microscope operating under either reflection-mode or transmission-mode illumination. A water droplet is created at the end of a syringe and then coated with a thin layer of silicone oil to mitigate evaporation. By applying mechanical pressure to the water droplet using a metal tip, the shape of the droplet is tuned to yield focusing properties amenable for microscopy. Images captured using the microscope demonstrate micron-scale resolution, variable magnification, and imaging quality comparable to that obtained by a conventional, laboratory-grade microscope. Next, we develop a surface plasmon resonance (SPR) sensor that exploits the index matching and coating capabilities of fluids. Conventional SPR sensor are implemented using an external light source, optical components to polarize incident light and guide light to and from a metal surface, a coupling device (such as a prism) to convert free-space light into surface plasmons on a metal surface and back into free-space light, and a light detector. Here, we develop a new SPR device architecture by combining several optical components via index matching fluid, which eliminates the need for a prism and integrates light delivery, light polarization control, surface plasmon coupling onto a thin, flexible substrate. We experimentally characterize the SPR device and find good agreement between experimental reflectivity measurements and a theoretical reflectivity model based on transfer-matrix formalism. By developing these new methods to integrate fluids for both microscopy and optical sensing applications, this work provides results that highlight both the promise and challenges of creating optical systems based on fluids.

description: We consider a particle moving on a 2-sphere in the presence of a constant magnetic field. Building on earlier work in the nonmagnetic case, we construct coherent states for this system. The coherent states are labeled by points in the associated phase space, the (co)tangent bundle of S^2. They are constructed as eigenvectors for certain annihilation operators and expressed in terms of a certain heat kernel. These coherent states are not of Perelomov type, but rather are constructed according to the "complexifier" approach of T. Thiemann. We describe the Segal--Bargmann representation associated to the coherent states, which is equivalent to a resolution of the identity.

Development of Poly (vinylidene fluoride) and Poly(vinyl pyrrolidone) based Solid Polymer Electrolyte for the Next Generation of Solid-state Sodium ion Battery

description: Solid-state sodium-ion batteries (ss-SIBs) are a promising alternative to commercially available lithium-ion batteries for next-generation energy storage applications due to the abundance and cost-effectiveness of sodium over lithium. Good electrochemical, mechanical, electrode compatibility, interfacial, and thermal stability properties of the solid form of electrolytes are considered as prerequisites to develop ss-SIBs. Among the organic and inorganic solid electrolytes, solid polymer electrolytes (SPE) are being considered as the promising ones based on the versatility of polymer materials and their potential optimization scope. However, low ionic conductivity and high interfacial resistance are the key drawbacks of typical SPEs. In this thesis, using a facile solution casting fabrication process, a high sodium-ion conductive, filler-less composite solid polymer electrolyte (SPE) film based on poly (vinylidene fluoride) polymer, poly (vinyl pyrrolidone) (PVP) binder, and NaPF6 salt has been studied for ss-SIB. A systematic characterization was carried out to investigate the microstructure and electrochemical properties of PVDF and PVP based SPEs via electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), thermogravimetric analysis (TGA), and Raman spectroscopy techniques. Total conductivities of 8.51 × 10–4 and 8.36 × 10–3 S cm–1 at 23 and 83 °C, respectively, were observed from the developed SPE. Obtained low activation energy (Ea) value suggests that in the composite polymer matrix Na-ion can easily be diffused. Identified β- and γ-phases of the PVDF polymer in the composite SPE matrix indicates the polar nature of the host polymer, which is believed to play an important role in decreasing the crystallinity as well as enhancing the Na+ conductivity. A hybrid symmetric half-cell assembly using Na electrode, 1 M NaClO4 in ethylene carbonate (EC) and propylene carbonate (PC) (EC/PC = 1:1 wt. %) and with SPE showed excellent Na plating–stripping performance at 10 mA cm–2 at 23 °C. A hybrid full cell with a SPE, a Na anode, and a Na3V2(PO4)3 cathode were assembled in a coin cell and electrochemical performance was evaluated.

description: Deep inspiration breath hold (DIBH) is a motion management technique that can be used to reduce dose to healthy tissue for right-sided breast cancer radiotherapy. With DIBH being a resource-intensive technique, it is typically reserved for patients that are initially scanned under free breathing (FB) conditions but cannot meet healthy tissue dose constraints during treatment planning. This workflow requires patients to return for a new DIBH scan, leading to inefficiencies and possible delays in treatment. This thesis focuses on developing a machine learning (ML) model to predict the optimal motion management technique during the computed tomography (CT) simulation appointment, from the patient anatomy in the FB CT-sim scan. Several models combining different supervised ML algorithms and anatomic measurements were assessed in terms of accuracy predicting the optimal motion management technique. Additionally, the timing and reliability of the anatomical measurements used in the models were examined via a blind study to determine the clinical feasibility of each model. It was found that a logistic regression ML model using two anatomical measurements yielded the most favourable balance of accuracy, timing, and reliability to predict the optimal motion management technique.
