description: We consider two nonlinear sigma models on de Sitter background which involve the same derivative interactions as quantum gravity but without the gauge issue. The first model contains only a single field, which can be reduced to a free theory by a local field redefinition; the second contains two fields and cannot be so reduced. Loop corrections in both models produce large temporal and spatial logarithms which cause perturbation theory to break down at late times and large distances. Many of these logarithms derive from the "tail" part of the propagator and can be summed using a variant of Starobinsky's stochastic formalism involving a curvature-dependent effective potential. The remaining logarithms derive from the ultraviolet and can be summed using a variant of the renormalization group based on a special class of curvature-dependent renormalizations. Explicit results are derived at 1-loop and 2-loop orders.

description: This research explored the microbial conversion of oleanonic acid by Aspergillus minisclerotigenes CGMCC 3.86. The scaled-up biotransformation processes produced ten distinct metabolites. Structural elucidation was performed through comprehensive NMR and HR-ESI-MS spectroscopic techniques, which led to the identification of three previously undocumented derivatives (compounds 6, 7, and 9). A. minisclerotigenes exhibited catalytic versatility in mediating multiple biochemical modifications, including carboxyl reduction, site-specific hydroxylation, glycosyl transfer, and cyclic ester formation. Furthermore, the inhibitory effects of metabolites on neuroinflammatory responses were evaluated using LPS-activated murine BV-2 microglial cell models. Among the tested compounds, derivatives 7, 9, and 10 displayed significant inhibition of nitric oxide production. These findings indicate that the biotransformed derivatives of oleanonic acid have potential as effective neuroinflammatory inhibitors.

description: Graphene is a truly two-dimensional atomic crystal with exceptional electronic and mechanical properties. Whereas conventional bulk and thin-film materials have been studied extensively, the key mechanical properties of graphene, such as tearing and cracking, remain unknown, partly due to its two-dimensional nature and ultimate single-atom-layer thickness, which result in the breakdown of conventional material models. By combining first-principles ReaxFF molecular dynamics and experimental studies, a bottom-up investigation of the tearing of graphene sheets from adhesive substrates is reported, including the observation of the formation of tapered graphene nanoribbons. Through a careful analysis of the underlying molecular rupture mechanisms, it is shown that the resulting nanoribbon geometry is controlled by both the graphene-substrate adhesion energy and by the number of torn graphene layers. By considering graphene as a model material for a broader class of two-dimensional atomic crystals, these results provide fundamental insights into the tearing and cracking mechanisms of highly confined nanomaterials.

description: Using Hinode SP and G-band observations, we examined the relationship between magnetic field structure and penumbral size as well as Evershed flow speed. The latter two are positively correlated with magnetic inclination angle or horizontal field strength within 1.5 kilogauss, which is in agreement with recent magnetoconvective simulations of Evershed effect. This work thus provides direct observational evidence supporting the magnetoconvection nature of penumbral structure and Evershed flow in the presence of strong and inclined magnetic field.

A hybrid precoding and signal detection framework for future wireless systems
Creators: name: Dsouza, Kevin Bradley
Publisher: name: University of British Columbia
Year: 2020

description: With energy efficiency and spectrum management being major concerns in future wireless systems, this thesis primarily focuses on the precoding and signal detection capabilities of next-generation wireless transceivers. In the first part of the thesis, we present a parallel framework to make hybrid precoding competitive in fast-fading environments. To enumerate, (i) a low-complexity algorithm which exploits the block diagonal phase-only nature of the analog precoder in a partially connected structure is proposed to arrive at a hybrid precoding solution for a multi-carrier single-user system using orthogonal frequency division multiplexing (OFDM), (ii) the original problem is broken down into independent subproblems of finding the magnitude and the phase components which are solvable in parallel, (iii) a per-RF chain power constraint is introduced instead of the sum power constraint over all antennas, which is much more practical in real systems, (iv) an alternating version of this scheme is proposed for increased spectral-efficiency gains, (v) wideband PCS architecture is critiqued for its applicability in future wireless systems and possible alternatives are discussed. In the second part of the thesis, we present a signal detection and time-frequency localization framework for smart transceivers. Although deep learning techniques for image analysis have been advancing at a breakneck pace for the past few years, their application to RF data has been relatively less explored. To enumerate our contributions, (i) we present a modification of an existing state-of-the-art object classification technique called Faster-RCNN (FRCNN) \cite{C108} for detection and time-frequency localization of the signal in a spectrogram of a wideband RF capture, (ii) insights into the design choices pertaining to the variables such as short-time Fourier transform (STFT) parameters, spectrogram and anchor sizes and network thresholds are discussed, (iii) synthetic data as per the recently proposed WiFi High Throughput (WiFi-HT) protocol \cite{wifi_ht} is generated and a mean average precision (mAP) of up to 0.9 is achieved when the model is trained and tested on positive signal to noise ratio (SNR) values, (iv) certain drawbacks of the model with respect to low SNR levels and disparate signal sizes are brought to light and possible solutions are discussed.

description: Purpose: Despite the positive approaches of the management of the sports system and the health system in public leisure, there are still numerous reports and documented shreds of evidence of mobility poverty and its consequences in the urban life of people in deprived provinces, which indicates a worrying social problem. Methods: Therefore, the researcher conducted this study by identifying the factors affecting participation in sports by using a grounded theory approach. The statistical population of the study included the elites of physical education and the sampling of the participants was done theoretically and purposefully. The data collection tool was a semi-structured interview and the data obtained from the interviews were analyzed using a Strauss and Corbin coding approach method. Results: In the results of code grouping, 39 components were obtained in five areas of causal, contextual, interventional, strategy, and consequence factors. Conclusion: Based on the research findings, it can be said that the popularization of sports in West Azerbaijan province can be achieved through the support of environmental factors, the positive intervention of managerial factors, resource contextualization, and finally, through behavioral factors. Therefore, it is necessary that the effective policies on sports participation in this province be identified and analyzed based on the model.

description: We propose a compound system consisting of a dielectric grating and a plasmonic resonance cavity embedded in the grating. Based on the interference effect between the surface mode supported by the dielectric grating and the plasmonic-induced cavity mode, this system could achieve slow light with group index more than 200 and transmission more than 75%. Meanwhile, we examine the effects of the period numbers of the compound system and photonic crystal superlattice made up of alternate layers of the grating and air on the properties of slow light.

description: High-resolution imaging-spectroscopy movies of solar active region NOAA 10998 obtained with the CRisp Imaging SpectroPolarimeter (CRISP) at the Swedish 1-m Solar Telescope show very bright, rapidly flickering, flame-like features that appear intermittently in the wings of the Balmer H-alpha line in a region with moat flows and likely some flux emergence. They show up at regular H-alpha blue-wing bright points that outline magnetic network, but flare upward with much larger brightness and distinct "jet" morphology seen from aside in the limbward view of these movies. We classify these features as Ellerman bombs and present a morphological study of their appearance at the unprecedented spatial, temporal, and spectral resolution of these observations. The bombs appear along magnetic network with footpoint extents up to 900km. They show apparent travel away from the spot along the pre-existing network at speeds of about 1 km/s. The bombs flare repetitively with much rapid variation at time scales of seconds only, in the form of upward jet-shaped brightness features. These reach heights of 600-1200km and tend to show blueshifts; some show bi-directional Doppler signature, and some seem accompanied with an H-alpha surge. They are not seen in the core of H-alpha due to shielding by overlying chromospheric fibrils. The network where they originate has normal properties. The morphology of these jets strongly supports deep-seated photospheric reconnection of emergent or moat-driven magnetic flux with pre-existing strong vertical network fields as the mechanism underlying the Ellerman bomb phenomenon.

description: After the first COVID-19 case was diagnosed in Germany, various measures limiting contact between people were introduced across the country. The implementation of these measures varied between jurisdictions and potentially had a negative impact on the psychological well-being of many people. However, the prevalence, severity, and type of symptoms of psychological burden has not been documented in detail. In the current study, we analysed various self-reported symptoms of psychological burden in a German sample. The dataset was collected between April 8th and June 1st, 2020, through an online survey measuring psychological burden using the ICD-10-symptom rating scale. More than 2,000 individuals responded to the survey, with a total of 1,459 complete datasets. Data was then sampled to compare (1) the new data to an existing demographically comparable reference dataset including a total of 2,512 participants who did not undergo any kind of contact restrictions or other pandemic measurements, and (2) psychological burden in two different German states. In line with recent observations from Germany, Italy, China, Austria and Turkey, we found a high prevalence of depressive symptoms in comparison to the reference sample. Furthermore, we found a high prevalence of eating disorder and compulsion symptoms. Especially younger adults and women reported a higher symptom severity compared to other groups during our measurement period. However, no difference between the two states in psychological burden was found.

description: The super-cooled $N3$ model exhibits an increasingly slow dynamics as density approaches the model's random closest packing density. Here, we present a direct measurement of the dynamical correlation function $G_4(r,t)$, showing the emergence of a growing length scale $ξ_4$ across which the dynamics is correlated. The correlation length measured, up to 120 lattice sites, power-law diverges as the density approaches $ρ_t$, the density at which the fluid phase of the model is predicted to terminate. It is shown that the four-point susceptibility, often used as an agent to estimate $ξ_4$, does not depend simply on the latter. Rather, it depends strongly on the short-range behavior of $G_4(r,t)$. Consequently, $χ_4$ peaks before $ξ_4$ reaches its maximal value. The two quantities should therefore be studied independently.

description: Interactions between electrons and lattice vibrations are responsible for a wide range of material properties and applications. Recently, there has been considerable interest in the development of resonant inelastic x-ray scattering (RIXS) as a tool for measuring electron-phonon (e-ph) interactions. Here, we demonstrate the ability of RIXS to probe the interaction between phonons and specific electronic states both near to, and away from, the Fermi level. We performed carbon $K$-edge RIXS measurements on graphite, tuning the incident x-ray energy to separately probe the interactions of the $π^*$ and $σ^*$ electronic states. Our high-resolution data reveals detailed structure in the multi-phonon RIXS features that directly encodes the momentum dependence of the e-ph interaction strength. We develop a Green's-function method to model this structure, which naturally accounts for the phonon and interaction-strength dispersions, as well as the mixing of phonon momenta in the intermediate state. This model shows that the differences between the spectra can be fully explained by contrasting trends of the e-ph interaction through the Brillouin zone, being concentrated at the $Γ$ and $K$ points for the $π^*$ states, while being significant at all momenta for the $σ^*$ states. Our results advance the interpretation of phonon excitations in RIXS, and extend its applicability as a probe of e-ph interactions to a new range of out-of-equilibrium situations.

description: Diarylmethanes play, in part, a pivotal role in the design of highly potent, chiral, nonracemic drugs whose bioactivity is typically affected by the substitution pattern of their arene units. In this context, certain arenes such as para-substituted benzenes or unsubstituted heteroarenes cause particular synthetic challenges, since such isosteric residues at the central methane carbon atom are typically indistinguishable for a chiral catalyst. Hence, the stereoselective incorporation of isosteric (hetero)arenes into chiral methane scaffolds requires the use of stoichiometrically differentiated building blocks, which is typically realized through preceding redox-modifying operations such as metalation or halogenation and thus associated with disadvantageous step- and redox-economic traits. As a counter-design, we report herein a generalized enantioselective synthesis of chiral diarylmethanes by means of an asymmetric migratory Tsuji–Wacker oxidation of simple stilbenes. The title protocol relies on the well-adjusted interplay of aerobic photoredox and selenium-π-acid catalysis to allow for the installation of a broad variety of arenes, including isosteric ones, into the methane core. Facial differentiation and regioselectivity are solely controlled by the selenium catalyst, which (a) renders the E/Z-configuration of the stilbene substrates inconsequential and (b) permits the stereodivergent synthesis of both product enantiomers from a single catalyst enantiomer, simply by employing constitutionally isomeric starting materials. Altogether, this multicatalytic platform offers the target structures with high levels of enantioselectivity in up to 97% ee, which has also been successfully exploited in expedited syntheses of antihistaminic (R)- and (S)-neobenodine.

description: Background and Aims: Working memory is among the essential components of executive function. Due to the different physiological and cognitive needs of open and closed motor exercises, this study aimed to investigate and assess the effects of open and closed exercises on the working memory of preschool children. Methods: This study was quasi-experimental with pre-test and post-test design. Thirty preschool children in Kermanshah were randomly divided into two open and closed exercise groups. Before the exercise protocol, all participants underwent Wechsler Intelligence Test and working memory pre-test with N-back software. Each group performed their one-hour training sessions for 12 weeks (three sessions per week). The exercise intensity was set at (60±5%) of the heart rate reserve level (HRR), with HR being monitored by a heart rate monitor. Data analysis was performed using the analysis of covariance (ANCOVA) by SPSS software v. 23. Results: The findings revealed a significant difference between open skill training (OSE) and closed skill training (CSE) (P≤0.05). OSE compared to CSE had a more significant effect on increasing children’s working memory. Conclusion: The findings demonstrated that 12 weeks of OSE has a more significant effect on increasing the working memory of preschool children (compared to CSE). Therefore, it is recommended that preschool children participate in OSE (higher cognitive load) to improve their working memory.

description: Significant evidence suggests that regular physical activity (PA) is correlated with numerous psychological benefits in adults such as improving body image and quality of life. However, this issue has not been differentiated between young and older adults. In addition, most previous studies used a self-reported questionnaire for measuring PA, the objectivity of which is limited in several ways. Hence, by using accelerometer technology for monitoring PA, this study was designed to examine the correlations of PA with body image and quality of life in young and older adults. In this cross-sectional study, we used objective actigraphy and survey data from 147 young and older adults, including 77 young and 70 older adults from Tehran, Iran. To examine our variables and hypothesis, the following instruments were implemented: the Persian version of the Multidimensional Body-Self Relations Questionnaire (MBSRQ), the Persian version of the Quality-of-Life Questionnaire (WHOQOL-BREF), and the ActiGraph wGT3X-BT for measuring PA. An independent t-test and a multivariate regression analysis were used to analyze the data. The weekly PA of both young and older adults was found to be lower than the recommended amount. Young adults engaged in significantly more weekly PA than older adults. For young adults, PA (including MPA, VPA, and MVPA) was generally found to be significantly correlated with body image and quality of life. For older adults, however, we found only significant correlations between VPA and quality of life. These findings indicated that PA is a critical concern in adults, particularly older adults. Accordingly, it is necessary to adopt appropriate strategies to promote an active lifestyle among adults.

Octadentate chelators for zirconium- and other metal-based radiopharmaceuticals
Creators: name: Buchwalder, Christian
Publisher: name: University of British Columbia
Year: 2020

description: Metal-based radiopharmaceuticals are critical in nuclear medicine for non-invasive diagnosis and treatment of serious diseases such as cancer. To be successfully deployed in such radioactive drugs, radiometal ions need to be stably sequestered by a suitable chelating agent. This work investigates a new class of octadentate chelating agents containing four 3-hydroxy-4-pyridinone (3,4-HOPO) entities with a focus on the development of new zirconium(IV) chelates. The diagnostic radionuclide zirconium-89 (89Zr, t1/2 78.41 h, Iβ+ 22.7%, Eβ+ mean 395.5 keV) is of particular interest for antibody-targeted positron emission tomography (immunoPET). The developed tetrakis(3,4-HOPO) chelator is capable of quantitatively sequestering 89Zr within 10 min at ambient temperature. The resultant Zr(IV) complex was found to be of exceptional thermodynamic stability (log β 50.3), showed a favourable pharmacokinetic profile in vivo, and exceeded the current standard Zr-chelator in direct in vitro stability tests. The tetrapodal chelator was derivatized in a multi-step synthesis for covalent attachment to targeting vectors or other carriers. The conjugation and ⁸⁹Zr-radiolabeling of the bifunctional chelator (BFC) was subsequently optimized and investigated in detail with two monoclonal antibodies, a model protein, and with polymeric nanoparticles. The long-term in vivo stability of the ⁸⁹Zr-radiochelate was assessed in a novel way over six days by utilizing long-circulating hyperbranched polyglycerol (HPG) nanoparticles. The radiochelate-nanocarrier conjugates were examined over six days by non-invasive positron emission tomography (PET) and in a biodistribution study. Although in vitro exams demonstrated extended plasma stability, these data revealed a physiologic susceptibility of the tetrakis(HOPO) complex attributed to kinetic lability. In addition to investigations with Zr(IV), the new ligand system was briefly explored with Fe(III), Ga(III), Y(III), Sm(III), Gd(III), Tb(III), Lu(III), and Bi(IIII) and indicated to be a promising chelator for iron(III), gallium(III), yttrium(III), and lanthanide ion coordination.

description: Global and local relational reasoning enable scene understanding models to perform human-like scene analysis and understanding. Scene understanding enables better semantic segmentation and object-to-object interaction detection. In the medical domain, a robust surgical scene understanding model allows the automation of surgical skill evaluation, real-time monitoring of surgeon's performance and post-surgical analysis. This paper introduces a globally-reasoned multi-task surgical scene understanding model capable of performing instrument segmentation and tool-tissue interaction detection. Here, we incorporate global relational reasoning in the latent interaction space and introduce multi-scale local (neighborhood) reasoning in the coordinate space to improve segmentation. Utilizing the multi-task model setup, the performance of the visual-semantic graph attention network in interaction detection is further enhanced through global reasoning. The global interaction space features from the segmentation module are introduced into the graph network, allowing it to detect interactions based on both node-to-node and global interaction reasoning. Our model reduces the computation cost compared to running two independent single-task models by sharing common modules, which is indispensable for practical applications. Using a sequential optimization technique, the proposed multi-task model outperforms other state-of-the-art single-task models on the MICCAI endoscopic vision challenge 2018 dataset. Additionally, we also observe the performance of the multi-task model when trained using the knowledge distillation technique. The official code implementation is made available in GitHub.

description: The luminosity, light curve, post--maximum spectrum, and lack of a progenitor on deep pre-outburst images suggest that SN 2010U was a luminous, fast nova. Its outburst magnitude is consistent with that for a fast nova using the Maximum Magnitude-Rate of Decline relationship for classical novae.

description: In this paper, we introduce a corresponding between bipartite graphs with a perfect matching and digraphs, which implicates an equivalent relation between the extendibility of bipartite graphs and the strongly connectivity of digraphs. Such an equivalent relation explains the similar results on $k$-extendable bipartite graphs and $k$-strong digraphs. We also study the relation among $k$-extendable bipartite graphs, $k$-strong digraphs and combinatorial matrices. For bipartite graphs that are not 1-extendable and digraphs that are not strong, we prove that the elementary components and strong components are counterparts.

description: Rapid transmission of contaminants in groundwater can occur in alluvial gravel aquifers that are permeated by highly conductive small-scale open framework gravels (OFGs). This open framework gravel structure and the associated distribution of hydraulic properties is complex, and so assessments of contamination risks in these aquifers are highly uncertain. Geostatistical models, based on lithological data, can be used to quantitatively characterize this structure. These models can then be used to support analyses of the risks of contamination in groundwater systems. However, these geostatistical models are themselves accompanied by significant uncertainty. This is seldom considered when assessing risks to groundwater systems. Geostatistical model uncertainty can be reduced by assimilating information from hydraulic system response data, but this process can be computationally challenging. We developed a sequential conditioning method designed to address these challenges. This method is demonstrated on a transition probability based geostatistical simulation model (TP), which has been shown to be superior for representing the connectivity of high permeability pathways, such as OFGs. The results demonstrate that the common modelling practice of adopting a single geostatistical model may result in realistic predictions being overlooked, and significantly underestimate the uncertainties of groundwater transport predictions. This has important repercussions for uncertainty quantification in general. It also has repercussions if using ensemble?based methods for history matching, since it also relies on geostatistical models to generate prior parameter distributions. This work highlights the need to explore the uncertainty of geostatistical models in the context of the predictions being made.

Affective interpretations of assisted driving interventions on a smart-wheelchair : an exploratory study
Creators: name: Estrada Gaspar, Ariadna M.
Publisher: name: University of British Columbia
Year: 2018

description: Allocating authority appropriately between humans and machines in shared control applications is crucial for the performance of the system. Particularly in the context of collaborative wheelchairs, the arbitration should be sensitive to user needs and preferences in order to avoid confusion and frustration. Current approaches to shared control for wheelchair navigation have been designed to handle objective and functional information such as goals and system states with limited analyses to subjective information such as the user’s feelings when an assisted driving intervention is introduced. This thesis explores user affective responses on smart-wheelchairs as a potential communication channel through which users could interact more effectively with their smart mobility device. We present an implementation of shared control paradigms from the smart-wheelchair literature and results from a study where participants reported their affective interpretation of the emerging behaviours.

description: The art of making structural, polymeric and metallic glasses is rapidly developing with many applications. A limitation to their use is their mechanical stability: under increasing external strain all amorphous solids respond elastically to small strains but have a finite yield stress which cannot be exceeded without effecting a plastic response which typically leads to mechanical failure. Understanding this is crucial for assessing the risk of failure of glassy materials under mechanical loads. Here we show that the statistics of the energy barriers ΔE that need to be surmounted changes from a probability distribution function (pdf) that goes smoothly to zero to a pdf which is finite at ΔE=0. This fundamental change implies a dramatic transition in the mechanical stability properties with respect to external strain. We derive exact results for the scaling exponents that characterize the magnitudes of average energy and stress drops in plastic events as a function of system size.
