description: Experimental data have revealed that neuronal connection efficacy exhibits two forms of short-term plasticity, namely, short-term depression (STD) and short-term facilitation (STF). They have time constants residing between fast neural signaling and rapid learning, and may serve as substrates for neural systems manipulating temporal information on relevant time scales. The present study investigates the impact of STD and STF on the dynamics of continuous attractor neural networks (CANNs) and their potential roles in neural information processing. We find that STD endows the network with slow-decaying plateau behaviors-the network that is initially being stimulated to an active state decays to a silent state very slowly on the time scale of STD rather than on the time scale of neural signaling. This provides a mechanism for neural systems to hold sensory memory easily and shut off persistent activities gracefully. With STF, we find that the network can hold a memory trace of external inputs in the facilitated neuronal interactions, which provides a way to stabilize the network response to noisy inputs, leading to improved accuracy in population decoding. Furthermore, we find that STD increases the mobility of the network states. The increased mobility enhances the tracking performance of the network in response to time-varying stimuli, leading to anticipative neural responses. In general, we find that STD and STP tend to have opposite effects on network dynamics and complementary computational advantages, suggesting that the brain may employ a strategy of weighting them differentially depending on the computational purpose.

description: We study numerically a 5D hybrid model which incorporates a split fermion scenario and bulk neutrinos. We perform a Monte Carlo analysis of the model in order to find the regions in the parameter space allowing for realization of the leptogenesis. We find that higher order Yukawa terms must be included in order the model to produce a CP violation and net baryon number sufficient for the creation of the observed baryon asymmetry of the Universe.

description: The LHC is foreseen to finally bring also the nuclear collisions to the TeV scale thereby providing new possibilities for physics studies, in particular related to the electro-weak sector of the Standard Model. We study here the Z and W production in proton-lead and lead-lead collisions at the LHC, concentrating on the prospects of testing the factorization and constraining the nuclear modifications of the parton distribution functions (PDFs). Especially, we find that the rapidity asymmetries in proton-nucleus collisions, arising from the differences in the PDFs between the colliding objects, provide a decisive advantage in comparison to the rapidity-symmetric nucleus-nucleus case. We comment on how such studies will help to improve our knowledge of the nuclear PDFs.

description: Attenuation of high-energy gamma rays by pair-production with UV, optical and IR extragalactic background light (EBL) photons provides a link between the history of galaxy formation and high-energy astrophysics. We present results from our latest semi-analytic models (SAMs), which employ the main ingredients thought to be important to galaxy formation and evolution, as well as an improved model for reprocessing of starlight by dust to mid- and far-IR wavelengths. These SAMs are based upon a Lambda-CDM hierarchical structural formation scenario, and are successful in reproducing a large variety of observational constraints such as number counts, luminosity and mass functions, and color bimodality. Our fiducial model is based upon a WMAP5 cosmology, and treats dust emission using empirical templates. This model predicts a background flux considerably lower than optical and near-IR measurements that rely on subtraction of zodiacal and galactic foregrounds, and near the lower bounds set by number counts of resolvable sources at a large number of wavelengths. We also show the results of varying cosmological parameters and dust attenuation model used in our SAM. For each EBL prediction, we show how the optical depth due to electron-positron pair-production is affected by redshift and gamma-ray energy, and the effect of gamma-ray absorption on the spectra of a variety of extragalactic sources. We conclude with a discussion of the implications of our work, comparisons to other models and key measurements of the EBL and a discussion of how the burgeoning science of gamma-ray astronomy will continue to help constrain cosmology. The low EBL flux predicted by our fiducial model suggests an optimistic future for further studies of distant gamma-ray sources.

description: In this work we explore the performance of CUDA in quenched lattice SU(2) simulations. CUDA, NVIDIA Compute Unified Device Architecture, is a hardware and software architecture developed by NVIDIA for computing on the GPU. We present an analysis and performance comparison between the GPU and CPU in single and double precision. Analyses with multiple GPUs and two different architectures (G200 and Fermi architectures) are also presented. In order to obtain a high performance, the code must be optimized for the GPU architecture, i.e., an implementation that exploits the memory hierarchy of the CUDA programming model. We produce codes for the Monte Carlo generation of SU(2) lattice gauge configurations, for the mean plaquette, for the Polyakov Loop at finite T and for the Wilson loop. We also present results for the potential using many configurations ($50\ 000$) without smearing and almost $2\ 000$ configurations with APE smearing. With two Fermi GPUs we have achieved an excellent performance of $200 \times$ the speed over one CPU, in single precision, around 110 Gflops/s. We also find that, using the Fermi architecture, double precision computations for the static quark-antiquark potential are not much slower (less than $2 \times$ slower) than single precision computations.

A possible signature of cosmic neutrino decoupling in the nHz region of the spectrum of primordial gravitational waves

description: In this paper we study the effect of cosmic neutrino decoupling on the spectrum of cosmological gravitational waves (GWs). At temperatures T>>1 MeV, neutrinos constitute a perfect fluid and do not hinder GW propagation, while for T<<1 MeV they free-stream and have an effective viscosity that damps cosmological GWs by a constant amount. In the intermediate regime, corresponding to neutrino decoupling, the damping is frequency-dependent. GWs entering the horizon during neutrino decoupling have a frequency f ~ 1 nHz, corresponding to a frequency region that will be probed by Pulsar Timing Arrays (PTAs). In particular, we show how neutrino decoupling induces a spectral feature in the spectrum of cosmological GWs just below 1 nHz. We briefly discuss the conditions for a detection of this feature and conclude that it is unlikely to be observed by PTAs.

description: Hard combinatorial optimization problems deal with the search for the minimum cost solutions (ground states) of discrete systems under strong constraints. A transformation of state variables may enhance computational tractability. It has been argued that these state encodings are to be chosen invertible to retain the original size of the state space. Here we show how redundant non-invertible encodings enhance optimization by enriching the density of low-energy states. In addition, smooth landscapes may be established on encoded state spaces to guide local search dynamics towards the ground state.

description: We calculate the model-independent radiative corrections to the Dalitz plot of K_{l3}^\pm decays to order (α/π)(q/M_1), where q is the momentum transfer and M_1 is the mass of the kaon. The final results are presented, first, with the triple integration over the variables of the bremsstrahlung photon ready to be performed numerically and, second, in an analytical form. These two forms are useful to crosscheck on one another and with other calculations. This paper is organized to make it accessible and reliable in the analysis of the Dalitz plot of precision experiments and is not compromised to fixing the form factors at predetermined values. It is assumed that the real photons are kinematically discriminated. Otherwise, our results have a general model-independent applicability.

description: Quasi and pseudo distributions provide a new approach to determining parton distribution functions (PDFs) from first principles' calculations of quantum chromodynamics (QCD). Here I calculate the flavor nonsinglet unpolarized quasi distribution at one loop in perturbation theory, using the gradient flow to remove ultraviolet divergences. I demonstrate that, as expected, the gradient flow does not change the infrared structure of the quasi distribution at one loop and use the results to match the smeared matrix elements to those in the $\ms$ scheme. This matching calculation is required to relate numerical results obtained from nonperturbative lattice QCD computations to light-front PDFs extracted from global analyses of experimental data.

Green infrastructure planning in Vancouver : addressing environmental justice with participatory resident workshops
Creators: name: Triffo, Taya Lynn
Publisher: name: University of British Columbia
Year: 2022

description: Urban rain gardens, wetlands, street trees: these “green infrastructures” (GI) are being used for a variety of urban planning priorities, like climate adaptation and rainwater management. Environmental justice scholars have stressed the need to develop green infrastructure for those who need it most (Anguelovski et al., 2021; Meerow & Newell, 2019). They have also identified “blind spots” in planning processes—from siting, through to public engagement, to maintenance—that may perpetuate uneven development or power imbalances (Brent et al., 2022; Zuniga-Teran et al., 2020). In Vancouver (Canada), modeling and mapping exercises have identified areas that can benefit most from GI development (“equity initiative zones” (City of Vancouver, 2022c); “areas in need of resources” (City of Vancouver, 2022b). This analysis helpfully indicates who is experiencing environmental vulnerability (e.g., heat, sea level rise), socio-economic vulnerability (e.g., low-income), and lack of urban green amenities (e.g., park access) in the city. As scholars recommend, however, there is a need to understand what these overlapping experiences mean to affected residents, and perhaps more importantly, what residents see as appropriate environmental and climate planning priorities as a result (Hoover et al., 2021). In this project, I facilitated two participatory workshops with residents who live in Vancouver’s eastern neighbourhoods, asking: what are residents’ self-identified GI priorities, challenges, and aspirations? Participants shared how GI projects can be adapted to meet their needs as renters, parents, seniors, immigrants, and low-income individuals. Participants wanted to see GI in the everyday spaces where they spend their time, noting possibilities such as developing green roofs directly on their affordable housing units. Second, participants stressed that improved livability (namely through public transit and affordable housing) can improve their overall experience with GI. Supplementary expert interviews (n=4) and an integrative document review (n=25) revealed other factors that might obscure or limit pathways for equitable development. These factors include opportunistic development patterns, budgetary constraints, and a lack of specific, actionable equity objectives. As the City of Vancouver continues to strive for equitable green infrastructure development, this project synthesizes potential entry points and limitations.

description: Analysing archival material from their major late medieval urban centres, including Cologne, Frankfurt-am-Main, and Hildesheim, this thesis provides a fresh examination of communities of lay voluntary poor called Cellites. Known for visiting the sick and burying the dead, they were once thought to have existed in conflict with the institutional Church. Tensions indeed persisted through the fifteenth century between proponents of a religious life lived outside of vows, and those who believed such a practice ran contrary to the very nature of religio. However, this thesis argues that Cellites were typically embraced by ecclesiastical and secular authorities because of their material and spiritual usefulness—specifically through the aid they provided body and soul by burying the dead and exhorting the dying. Drawing out the interactions between ecclesiastics, magistrates, and individual Cellite houses contributes to scholarship in two main ways. First, it supports the growing consensus that later medieval religion was far richer than the dichotomies of lay/clerical or secular/religious have allowed us to see. Second, it adds to the lively discussion about the space ‘in between’ heresy and order by demonstrating how the Cellites, rather than being regularised or repressed, carved out an identity for themselves while making their own choices regarding forms of the religious life. The thesis proceeds chronologically in the first two chapters, and thematically in the last two. Examining a legal case from the Council of Constance (1414-18), Chapter One shows how clerics framed Cellite communities as fostering virtue rather than usurping the prerogatives of religious. Chapter Two demonstrates that in the following decades, the ways in which individual houses negotiated their status was shaped by their local contexts, but that corporately the Cellites faced no existential threat; houses chose to adopt the Augustinian Rule in the 1460s-70s not to avoid dissolution but to gain additional privileges. The second portion of the thesis turns to the ways in which the Cellites contributed to the maintenance of a Christian society. Chapter Three argues that clergy and magistrates regarded Cellite burial of the dead as beneficial to the common good because it ensured the poor as well as the rich were treated with dignity. Chapter Four shows that this social benefit was not only physical: secular and ecclesiastical authorities also praised the Cellites for aiding their broader communities spiritually, by providing exhortations at the deathbed about the basics of the faith. Taken together, these chapters push us beyond seeing lay religious as mere subjects of reform, illuminating instead how they could be active participants in it.

Technologies used to develop the application together with ballistic models are presented in comparison with real life training applications. The application allows the user  to train using several pre-set cases for specific aerial targets. Through specific e-learning strategies the user capability and experience is enriched altogether with specific automatism directly related to the field of anti-aircraft missile training. Key advantages of the applications are presented amongst which we mention low-cost, repeatability capability, detailed analysis of missile firing tests as well as detailed equipment resemblance. The interface is realized with great detail and special care is given to the real-life feeling of various buttons and switches. The application tries to give to the trainee a real-life feeling with smooth performance capability.

title: Exploring adolescent fast bowling: a mixed methods approach
Creators: name: Hislen, Scott
Publisher: name: Edinburgh Napier University
Year: 2023

description: Introduction: Limited mixed methods research has been conducted into the physical and skills requirements of a developing fast bowler.

Methods: This mixed methods study explored the interrelationship between the physical and skill requirements in developing fast bowlers in two parts. Part one, involved scripted online interviews with six professional fast bowling cricket coaches and were analysed using reflexive thematic analysis. Part two involved implementing a training model for developing fast bowlers. Six developing academy-level fast bowlers (FB) (18.1 ± 1.1 years) completed a periodised bowling-specific programme. Pre/post-tests across various physical qualities were recorded with changes measured using a paired sample t-test (p≤ 0.01) and effect sizes.

Results: Interview themes indicate skill specific warm-ups can be used in skill sessions to physically and technically prepare fast bowlers, while strength and power abilities were perceived important characteristics of fast bowling performance. Fast bowling coaches and strength and conditioning coaches should consider these physical characteristics when designing programmes for developing fast bowlers. Additionally, coaches suggested individualised programmes with strength and conditioning coaches requiring a technical understanding of fast bowling. Post 14-week intervention, group relative changes showed improvement in strength (+8%), power (+2%), muscular endurance (+45%), speed (-6%) and aerobic capacity (+3).

Conclusion: A multi-disciplinary collaborative approach should be used to provide developing fast bowlers with individualised technical and physical support to optimise performance. Although positive improvements were recorded post intervention, further work is needed on how this can increase bowling speed. Future research should consider the benefits of mixed methods research, where the technical and physical characteristics are closely aligned within developmental programmes, to enhance performance and reduce injury in this population.

description: We investigate the sensitivity of the composite cellular automaton of H. Fukś [Phys. Rev. E 55, R2081 (1997)] to noise and assess the density classification performance of the resulting probabilistic cellular automaton (PCA) numerically. We conclude that the composite PCA performs the density classification task reliably only up to very small levels of noise. In particular, it cannot outperform the noisy Gacs-Kurdyumov-Levin automaton, an imperfect classifier, for any level of noise. While the original composite CA is nonergodic, analyses of relaxation times indicate that its noisy version is an ergodic automaton, with the relaxation times decaying algebraically over an extended range of parameters with an exponent very close (possibly equal) to the mean-field value.

Exploring the perspectives of Iranian immigrant parents in Canada on the concept of emotions
Creators: name: Arquillano, Esther
Publisher: name: University of British Columbia
Year: 2022

description: Canada has previously and continues to be built on the immigration of individuals from diverse backgrounds. Immigrating to a new country involves adapting to a new culture and set of norms (Beiser, 2009; Chuang, 2019; Vezina & Houle, 2017), where parents and children may face trauma and be at risk for developing physical and mental health issues (Beiser, 2005; Chuang, 2019; Pritchard & Ramos, 2018). Emotion-related skills play a key role in combatting these issues and increasing children’s future success, suggesting the importance of supporting the development of emotion-related skills early in childhood (Gagne et al., 2018). However, parents from a non-Western country resettling in Canada may have different perceptions and understandings of emotion that can impact the development of a child’s emotion-related skills. There is little research on how Iranian parents who are immigrants or refugees in Canada perceive the construct of emotions and the role of emotions in their parenting. Thus, in this study those aspects will be explored with Iranian Canadian parents. This exploratory qualitative descriptive study employed semi-structured interviews and photos as elicitation devices to understand the perceptions Iranian parents who are immigrants with young children hold regarding the construct of emotion and their perception on emotions in their parenting. A total of four parents with children between the ages of six and eight living in British Columbia and Ontario who immigrated to Canada at least five years ago participated in the study. A thematic analysis (Braun & Clark, 2006) of interview transcripts was used to identify patterns within the data and generate in vivo codes to describe the lived experiences of the participants. Analysis of semi-structured online interviews with each participant revealed that parents perceived emotion experiences to vary based on an individual’s age and environment and that the role of emotions was for protection and parents served as role models and teachers of emotions. These themes revealed that emotions exist everywhere and have cultural influences and that protecting their children was important when dealing with and sharing emotions. Moreover, each participant revealed that the environment they found themselves in impacted the emotions they experienced.

description: Semantic segmentation for aerial imagery is a challenging and important problem in remotely sensed imagery analysis. In recent years, with the success of deep learning, various convolutional neural network (CNN) based models have been developed. However, due to the varying sizes of the objects and imbalanced class labels, it can be challenging to obtain accurate pixel-wise semantic segmentation results. To address those challenges, we develop a novel semantic segmentation method and call it Contextual Hourglass Network. In our method, in order to improve the robustness of the prediction, we design a new contextual hourglass module which incorporates attention mechanism on processed low-resolution featuremaps to exploit the contextual semantics. We further exploit the stacked encoder-decoder structure by connecting multiple contextual hourglass modules from end to end. This architecture can effectively extract rich multi-scale features and add more feedback loops for better learning contextual semantics through intermediate supervision. To demonstrate the efficacy of our semantic segmentation method, we test it on Potsdam and Vaihingen datasets. Through the comparisons to other baseline methods, our method yields the best results on overall performance.

Topological Crystalline Insulators

subject: FOS: Physical sciences

description: The recent discovery of topological insulators has revived interest in the topological properties of insulating band structures. In this work, we extend the topological classification of insulating band structures to include certain point group symmetry of crystals. We find a class of three-dimensional "topological crystalline insulators" which have metallic surface states on certain high symmetry crystal surfaces. These topological crystalline insulators can be viewed as the counterpart of topological insulators in materials without spin-orbit coupling. Their surface states have quadratic band degeneracy instead of linear Dirac dispersion. Their band structures are characterized by new Z2 invariants. We hope this work will enlarge the family of topological phases in band insulators and stimulate the search for them in real materials.

description: To alleviate the computational cost associated with on-the-fly ab initio semiclassical calculations of molecular spectra, we propose the single-Hessian thawed Gaussian approximation, in which the Hessian of the potential energy at all points along an anharmonic classical trajectory is approximated by a constant matrix. The spectra obtained with this approximation are compared with the exact quantum spectra of a one-dimensional Morse potential and with the experimental spectra of ammonia and quinquethiophene. In all cases, the single-Hessian version performs almost as well as the much more expensive on-the-fly ab initio thawed Gaussian approximation and significantly better than the global harmonic schemes. Remarkably, unlike the thawed Gaussian approximation, the proposed method conserves energy exactly, despite the time dependence of the corresponding effective Hamiltonian, and, in addition, can be mapped to a higher-dimensional time-independent classical Hamiltonian system. We also provide a detailed comparison with several related approximations used for accelerating prefactor calculations in semiclassical simulations.

description: We describe general features of frequency-dependent charge transport near strongly interacting quantum critical points in 2+1 dimensions. The simplest description using the AdS/CFT correspondence leads to a self-dual Einstein-Maxwell theory on AdS_4, which fixes the conductivity at a frequency-independent self-dual value. We describe the general structure of higher-derivative corrections to the Einstein-Maxwell theory, and compute their implications for the frequency dependence of the quantum-critical conductivity. We show that physical consistency conditions on the higher-derivative terms allow only a limited frequency dependence in the conductivity. The frequency dependence is amenable to a physical interpretation using transport of either particle-like or vortex-like excitations.

description: Hybrid-ARQ protocols have become common in many packet transmission systems due to their incorporation in various standards. Hybrid-ARQ combines the normal automatic repeat request (ARQ) method with error correction codes to increase reliability and throughput. In this paper, we look at improving upon this performance using feedback information from the receiver, in particular, using a powerful forward error correction (FEC) code in conjunction with a proposed linear feedback code for the Rayleigh block fading channels. The new hybrid-ARQ scheme is initially developed for full received packet feedback in a point-to-point link. It is then extended to various different multiple-antenna scenarios (MISO/MIMO) with varying amounts of packet feedback information. Simulations illustrate gains in throughput.

description: The Student Money Management Office (SMMO) implementation study seeks to document the evolution of the program from the initial development and implementation starting in July 2016, continuing throughout the duration of the program. The study examines modifications in program design in order to understand how, when, and why changes were made. It is an essential source of information for interpreting the outcomes and impacts of student participation in the programs supported under the grant. This report is divided into three main sections: text messaging interventions, financial literacy outreach and education, and student access to financial aid information. This report presents detailed information regarding each specific initiative, progress made on the implementation of the initiative, key modifications made during the 2017-2018 program year, and factors that impede or support the program in meeting the stated objectives. The final section of this report provides a summary discussion and presents recommendations for next steps for the SMMO project.

Analysis of a mathematical model for the growth of cancer cells

description: In this paper, a two-dimensional model for the growth of multi-layer tumors is presented. The model consists of a free boundary problem for the tumor cell membrane and the tumor is supposed to grow or shrink due to cell proliferation or cell dead. The growth process is caused by a diffusing nutrient concentration $σ$ and is controlled by an internal cell pressure $p$. We assume that the tumor occupies a strip-like domain with a fixed boundary at $y=0$ and a free boundary $y=ρ(x)$, where $ρ$ is a $2π$-periodic function. First, we prove the existence of solutions $(σ,p,ρ)$ and that the model allows for peculiar stationary solutions. As a main result we establish that these equilibrium points are locally asymptotically stable under small perturbations.

Identification of regulatory mechanisms in governing gene expression from the inactivated X chromosome
Creators: name: Leung, Tiffany Ying
Publisher: name: University of British Columbia
Year: 2022

description: X chromosome inactivation (XCI) is the process in which one copy of the X chromosomes in females (XX) is randomly silenced to achieve dosage compensation of gene expression from X chromosome of males (XY). XCI is known to be incomplete, resulting in a subset of genes on the inactive X (Xi) being expressed. Genes along the X chromosome are classified into three categories based upon their expression from the Xi: subject, escape and variable. Escape genes, corresponding to 15% of X-linked genes, are generally expressed from the Xi at a substantially lower level compared to the active X (Xa). The underlying mechanisms in controlling escape from the heterochromatic state of Xi has been a long-standing question. While there is evidence that supports a role for intrinsic DNA elements in the escape XCI, they have not yet been identified. With increasing amounts of data for transcription factor (TF) binding sites, the objective of this thesis was to identify the regulatory TFs facilitating the ability of genes to escape XCI via a bioinformatics approach using empirical data. ChIP-seq peaks of 155 TFs from the ReMap database were assessed for enrichment at regulatory regions of 55 escape genes. 19 TFs were identified via enrichment analysis in the transcription start site regions of escape genes. Co-binding of pairs of enriched TFs were characterized by gene set similarity between the target genes. Of the 155 TFs examined, ZFP36, an RNA binding protein that alters RNA stability, showed importance in both enrichment analysis and co-binding analysis. An initial exploration of methods to compare the structures of Xi and Xa were undertaken using ChIA-PET data, providing insights into the limitations of current data resources and opportunities for future studies to inform the topographical organization of escape genes within Xi. The results of this thesis refined our knowledge on cis-regulatory elements and trans-acting factors potentially involved in escape of XCI. This list of enriched TF may be useful in future analyses, experimental or computational, to further determine their sufficiency and necessity in the escape of XCI.
