description: The significant increase of the transmission of multimedia content over Internet are demanded new delivery strategies to assure a good quality of experience of the users. Transmission of video over packet networks is not an easy task due to multiple fluctuations of the network conditions. One possibility to improve the quality of some video streaming services is the combinate use of the scalable video coding and cross layer mechanisms that allow applications to adapt its traffic stream to the resources network that are available. In this paper, it is presented a performance evaluation of the three main scalability techniques: CGS (Coarse-Grained Scalability), FGS (Fine Grain scalability) and MGS (Medium Grain Scalability). In particular, we focus on determining what method is more appropriated for video transmission taking into account some video quality metrics like PSNR (Peak Signal-to-Noise Ratio) and decoded frame rate. The results reveal that the rate-adaptive strategy and the MGS technique help avoid or reduce the congestion in networks obtaining a better quality in the received videos.

description: We derived the influence of dark matter (DM) decays and annihilations on structure formation. The energy deposited by DM decays and annihilations into metal free halos both increases the gas temperature and enhances the formation of molecules. Within the primordial halos the temperature increase generally dominates over the molecular cooling, slightly delaying the collapse. In fact, the critical mass for collapse is generally higher than in the unperturbed case, when we consider the energy input from DM. In presence of DM decays and/or annihilations the fraction of baryons inside collapsed metal free halos should be slightly less (~0.4) than the expected cosmological value.

Ski injury prevention: an epidemiological investigation of the social, behavioural and environmental determinants of injury
Creators: name: Cadman, Robert Edwin
Publisher: name: University of British Columbia
Year: 2009

description: Abstract: This dissertation research is a case study of the distribution and determinants of morbidity among a population of young (under 18 years) alpine skiers and snowboarders at one major North American ski resort. It is an interdisciplinary investigation that encompasses sports medicine, epidemiology, education, sociology and health promotion. The research includes two phases, a retrospective case series analysis of 2,139 injury events during the 1992 ski season and a 1993 prospective case series analysis of 540 injured alpine skiers and snowboarders in three age groups (0-6, 7-12, 13-17 years). The study employed ski patrol data and a specially designed questionnaire administered to over 800 uninjured skiers and 114 injured skiers. It was framed using the PRECEDEPROCEED health promotion planning model. The research employed replicable and reliable skier visit data that enabled calculations for age-specific incidence rates of injury. The major findings include: 1) adolescents (13-17 years) have the highest incidence of injury in the skiing population; 2) injury patterns differ between males and females as well as between alpine skiers and snowboarders; 3) children on school-sponsored ski programs are injured at a significantly greater rate than their non-school cohorts; 4) weather variables do not play a significant role in general injury rates; 5) environmental factors that include both the social and physical environments influence skiing behaviour. Alpine skiing and snowboarding injuries are both predictable and preventable events. In light of the findings, several intervention strategies are discussed that may reduce the incidence and/or severity of injury by influencing the social, behavioural and environmental determinants of skiing-related activities.

In combat soldiers resting urinary metabotypes correlate with the development of Irritable Bowel Syndrome symptoms during stress

Creators: name: Wilder-Smith, Clive
Publisher: name: F1000Research
Year: 2015

description: Protracted and mixed psychological and physical combat-training stress induced Irritable Bowel Syndrome in a subgroup of soldiers. These soldiers demonstrated a distinct resting urinary metabotypic signature compared to those soldiers not developing GI symptoms. Notable metabotypic differences were found in energy metabolism, amino acid, fatty acid and nucleic acid constituents, in components of the pain/inflammation/stress axis, as well as in microbiome-related metabolites. These data suggest individuals more prone to stress-mediated GI dysfunction and pain have an identifiable metabotype at rest. Further validation in stressful operational situations will allow a more detailed understanding of the perturbed metabolic pathways and potential preventative measures in at-risk populations.

description: AstroDS is a distributed storage for Cosmic Ray Astrophysics. The primary goal of Astro DS is to gather data measured by the instruments of various physical experiments such as TAIGA, TUNKA, KASCADE into global storage and provide the users with a standardized user-friendly interface to search for the datasets that match certain conditions. AstroDS consists of a set of distributed microservices components that communicate with each other through the Internet via REST API. The core component of AstroDS is the Data Aggregation Service that orchestrates other components to provide access to data. The development process of AstroDS started in 2019. This paper describes the current design and implementation of the Data Aggregation Service and also the benefits it brings to the astrophysical community in the early state.

Temporal Evolution of Pair Attenuation Signatures in Gamma-Ray Burst Spectra
Creators: name: Baring, Matthew G.
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The spectra obtained above 100 MeV by the EGRET experiment aboard the Compton Gamma-Ray Observatory for a handful of gamma-ray bursts has given no indication of any spectral attenuation that might preclude detection of bursts at higher energies. With the discovery of optical afterglows and counterparts to bursts in the last few years, enabling the determination of significant redshifts for these sources, it is anticipated that profound spectral attenuation will arise in the Gamma-Ray Large Area Space Telescope (GLAST) energy band of 30 MeV-300 GeV for many if not most bursts. This paper explores time-dependent expectations for burst spectral properties in the EGRET/GLAST band, focusing on how attenuation of photons by pair creation internal to the source generates distinctive spectral signatures. The energy of spectral breaks and the associated spectral indices provide valuable information that constrains the bulk Lorentz factor of the GRB outflow at a given time. Moreover, the distinct temporal behavior that is present for internal attenuation is easily distinguished from extrinsic absorption due to intervening cosmic background fields. These characteristics define palpable observational goals for both spaced-based hard gamma-ray experiments such as GLAST, and ground-based Cherenkov telescopes, and strongly impact the observability of bursts above 300 MeV.

Frequencies, chaos and resonances: a study of orbital parameters of nearby thick disc and halo stars

description: We study the distribution of nearby thick disc and halo stars in subspaces defined by their characteristic orbital parameters. Our aim is to establish the origin of the structure reported in particular, in the $R_{\rm max}-z_{\rm max}$ space. To this end, we compute the orbital parameters and frequencies of stars for a generic and for a Stäckel Milky Way potential. We find that for both the thick disc and halo populations very similar prominent substructures are apparent for the generic Galactic potential, while no substructure is seen for the Stäckel model. This indicates that the origin of these features is not merger-related, but due to non-integrability of the generic potential. This conclusion is strengthened by our frequency analysis of the orbits of stars, which reveals the presence of prominent resonances, with $\sim 30\%$ of the halo stars associated to resonance families. In fact, the stars in resonances define the substructures seen in the spaces of characteristic orbital parameters. Furthermore, we find that some stars in our sample and in debris streams are on the same resonance as the Sagittarius dwarf, suggesting this system has also influenced the distribution of stars in the Galactic thick disc and halo components. Our study constitutes a step towards disentangling the imprint of merger debris from substructures driven by internal dynamics. Given their prominence, these resonant-driven overdensities could potentially be useful to constrain the exact form of the Galactic potential.

description: The dynamics of charge qubit in double quantum dot coupled to phonons is investigated theoretically. The static bias is considered. By means of the perturbation approach based on unitary transformations, the dynamical tunneling current is obtained explicitly. The biased system displays broken symmetry and a significantly larger coherence-incoherence transition critical point $α_{c}$. We also analyzed the decoherence induced by piezoelectric coupling phonons in detail. The results show that reducing the coupling between system and bath make coherence frequency increase and coherence time prolong. To maintain quantum coherence, applying static bias also is a good means.

description: Recently, consumer-facing health technologies such as Artificial Intelligence (AI)-based symptom checkers (AISCs) have sprung up in everyday healthcare practice. AISCs solicit symptom information from users and provide medical suggestions and possible diagnoses, a responsibility that people usually entrust with real-person authorities such as physicians and expert patients. Thus, the advent of AISCs begs a question of whether and how they transform the notion of medical authority in everyday healthcare practice. To answer this question, we conducted an interview study with thirty AISC users. We found that users assess the medical authority of AISCs using various factors including automated decisions and interaction design patterns of AISC apps, associations with established medical authorities like hospitals, and comparisons with other health technologies. We reveal how AISCs are used in healthcare delivery, discuss how AI transforms conventional understandings of medical authority, and derive implications for designing AI-enabled health technology.

Special attention is paid to the so-called β-term and the Gilbert damping, α, in the presence of electrons' spin-relaxation processes, which are modeled by quenched magnetic impurities. Two types of forces that the electric/spin current exerts on magnetization are identified based on a general formula relating the force to the torque.

description: The detachment and calculation of functionalities from a vehicle into a cloud creates new chances. By linking different data sources with the in-vehicle data in the cloud, an optimization of these functionalities in terms of en-ergy efficiency can be applied. For example, the Heating, Ventilation and Air Conditioning (HVAC) consumes up to 30% of total energy in a vehicle. Electric vehicles in particular lead to these high values because they are not able to re-cover the waste heat from combustion engines for interior heating. Therefore, the optimization of energy efficient strategies with respect to the vehicle energy management system becomes more relevant. Forecasts of the interior vehicle temperature are directly related to the HVAC energy consumption. This work focuses on the implementation and accuracy evaluation of Recurrent Neural Networks (RNN) for interior vehicle temperature forecasting.

Publisher: name: University of Alberta Library
Year: 2023

SSHRC IDG awarded 2023: Pakistan ranks poorly in the world when it comes to gender equality. Socio­cultural barriers, limited access to schooling, and discriminatory gender norms have negatively impacted women’s socio­economic development and inclusion in the formal financial system. Women play a major role in the transmission of financial skills to future generations and they also live longer than men, making financial literacy and numeracy essential for their economic well­being and empowerment. A qualitative community­ based participatory research approach will be used to actively engage underserved Pakistani women throughout the study. Study findings will inform the development of new and more effective financial learning programs for underserved women, contributing to evidence­based practice and the scholarly literature.

SSHRC IG awarded 2023: This project will investigate the limits imposed by the cognitive system on how three languages spanning the pectrum of linguistic diversity --- English, Mandarin and Kalaallisut --- perform a basic communicative function: drawing the listener's attention to new information. These languages differ vastly in the relative complexity of the components of their grammars, such as prosody (the melody and rhythm of speech) and morpho-syntax (word and sentence formation).The project will address this knowledge gap by comparing English, Mandarin and Kalaallisut through experimental research and statistical analysis. In addition to analyzing these representative languages with uniform methods, the project will take an innovative step and manipulate the flexibility of different grammatical components experimentally within each language. Thiswill allow us to directly assess the assumed interplay of different components of grammar and overall limits on linguistic complexity.

description: Introduction
Psoriasis is a chronic skin disease affecting quality of life and causing pruritus. The factors influencing itch and its impact on the quality of life in Thai psoriasis patients are unknown. We aimed to identify these factors and their effect on quality of life. Material and methods
In this questionnaire-based cross-sectional study, we included patients with psoriasis who received treatment at Chulabhorn Hospital in Thailand from January 2019 to July 2021. Interviewer is the non-dermatologist practician. The patient’s information was collected, including demographic data, Itch Numeric Rating Scale (Itch NRS) score, factors affecting itch, and score on the Thai version of the Dermatology Life Quality Index (DLQI). We performed descriptive statistics and logistic regression analysis.
Results
Of 100 participants, most (99%) experienced itching, with a moderate degree of pruritus (mean Itch NRS score 6.5 ± 2.6) and a moderate effect on quality of life (mean DLQI score 9.4 ± 6.2). Factors associated with itch aggravation were dry skin (p-value = 0.003) and heat and humidity (p-value = 0.042). The results of binary logistic regression revealed that factors associated with moderate-to-extremely large DLQI scores were itch intensity (no-to-mild vs. moderate-to-severe itch: odds ratio [OR] = 13.33; 95% confidence interval [CI] = 2.72–65.32, p < 0.001; and adjusted odds ratio [AOR] = 31.17; 95% CI = 4.55–213.36; p < 0.001. Conclusions
Our findings revealed that the quality of life among patients with psoriasis is their greatest concern. Eliminating the itch intensity that affects their quality of life is crucial but remains challenging in Thailand.

description: We use the recently developed Kinetic Field Theory (KFT) for cosmic structure formation to show how non-linear power spectra for cosmic density fluctuations can be calculated in a mean-field approximation to the particle interactions. Our main result is a simple, closed and analytic, approximate expression for this power spectrum. This expression has two parameters characterising non-linear structure growth which can be calibrated within KFT itself. Using this self-calibration, the non-linear power spectrum agrees with results obtained from numerical simulations to within typically $\lesssim10\,\%$ up to wave numbers $k\lesssim10\,h\,\mathrm{Mpc}^{-1}$ at redshift $z = 0$. Adjusting the two parameters to optimise agreement with numerical simulations, the relative difference to numerical results shrinks to typically $\lesssim 5\,\%$. As part of the derivation of our mean-field approximation, we show that the effective interaction potential between dark-matter particles relative to Zel'dovich trajectories is sourced by non-linear cosmic density fluctuations only, and is approximately of Yukawa rather than Newtonian shape.

I hate this lesson! Understanding how children manage their affect during online reading lessons

Publisher: name: University of Alberta Library
Year: 2023

SSHRC IDG awarded 2023: Many of us have been frustrated when trying to learn something that we feel is difficult. Some of us chose to quit when facing frustration and others chose to work more so that they can overcome these difficulties. While several theories detail the role of adults’ emotions (i..e, affect) in language learning or technology enhanced learning, few (if any) detail how children’s feelings fluctuate when they are completing literacy lessons online. Moreover, existing theories have yet to detail how children monitor and manage their feelings (i.e., meta­affect) to maintain their focus and support their learning. This project will use participatory design methods to adapt existing instruments so that they are appropriate for use with children. We will then use these instruments to better understand how children behave, how they feel, and how they manage their feelings when engaged in online reading lessons.

description: A group is irreducibly represented if it has a faithful irreducible unitary representation. For countable groups, a criterion for irreducible representability is given, which generalises a result obtained for finite groups by W. Gaschütz in 1954. In particular, torsionfree groups and infinite conjugacy class groups are irreducibly represented. We indicate some consequences of this for operator algebras. In particular, we charaterise up to isomorphism the countable subgroups $Δ$ of the unitary group of a separable infinite dimensional Hilbert space $\Cal H$ of which the bicommutants $Δ''$ (in the sense of the theory of von Neumann algebras) coincide with the algebra of all bounded linear operators on $\Cal H$.

Interpretative Phenomenological Analysis

description: Rationale and Aims: There is speculation that young Black men (YBM) exposed to gang-affiliated violence are likely to have negative impacts on their psychological functioning, but not enough research has explored this. It is important that we hear from YBM themselves as experts in their lived experiences. The current research aimed to listen to YBM in London, examining trauma relating to gang-affiliated violence and how YBM make sense of their experiences. Methods: This qualitative study utilised an Interpretative Phenomenological Analysis (IPA) to explore how eight YBM between the ages of 19-32 storied their lived experiences of gang-affiliated violence and trauma. Findings: Three Group Experiential Themes (GETs) and eight subthemes were identified from the data. Together, the themes described the complex interlink of human experience marked by trauma, socially deprived environments, systemic abuses, discrimination, healing, and coping. Participants attempted to make sense of their longstanding traumas and the subsequent responses. These traumatising experiences elicited fear among other emotions. The persistent nature of violence in their communities created a sense of normalisation, and behaviours were adopted to navigate these threats. These threats were not only from peers but from the police also. Attempts were then made to cope with the ongoing threats of violence. Discussion: Findings of this study were discussed in relation to the wider literature. This research produced new knowledge about how YBM exposed to gang-affiliated violence make sense of their experiences, and the trauma responses they portray which challenge traditional perceptions of trauma and PTSD. This research has the potential to influence developments in statutory services, as well as raising awareness and inspiring action. Clinical implications for working with this population were also considered.

description: Planar cell polarity (PCP) is essential for generating highly organized tissue structures and for directional cell movement/migration. The role of PCP in embryogenesis is well-documented, however its role in adult pathologies, such as cancer, is a relatively new field of research. A growing number of publications imply a significant role for PCP proteins in cancer progression and metastasis. PCP is governed by several cytosolic proteins and transmembrane receptors including the G-protein coupled receptor CELSR1. Research studies have raised the hypothesis that CELSR1 acts as a tumour suppressor in breast cancer. Our research aim was to characterise an in-vitro model to understand the molecular/cellular basis of the role of CELSR1 in breast cancer. Computational biology was used to assess CELSR1 expression in breast cancer sub-types and its impact on patient survival. Characterisation of breast cancer cell lines representing increasingly invasive breast cancer was performed through qPCR and western blot analysis to investigate CELSR1 expression and immunocytochemistry to investigate CELSR1 protein distribution. RT-PCR and Sanger sequencing were used to assess differential splicing of the C-terminus of CELSR1. Gain and loss-of-function assays were conducted to test the tumour suppressive functions of CELSR1. Bioinformatics analysis has revealed that CELSR1 expression is increased in the less invasive Luminal A subtype of breast cancer, and that higher expression of CELSR1 has positive impact on overall patient survival. In vitro studies of common breast cancer cell lines revealed that CELSR1 is more highly expressed in less invasive luminal type cell lines, but its expression is reduced in more invasive type cell lines. Furthermore, whilst less invasive breast cancer cell lines exhibit cortical enrichment of CELSR1, CELSR1 becomes localised in intracellular punctate structures adjacent to the nucleus within the highly invasive breast cancer cells. Finally, we find that overexpression of Celsr1 in highly invasive breast cancer cell lines reduces their migratory ability and proliferation. Taken together, our study is consistent with a role for CELSR1 as a tumour suppressor in breast cancer. Future studies will aim to decipher its mechanism of action.

description: Data-dependent hashing methods have demonstrated good performance in various machine learning applications to learn a low-dimensional representation from the original data. However, they still suffer from several obstacles: First, most of existing hashing methods are trained in a batch mode, yielding inefficiency for training streaming data. Second, the computational cost and the memory consumption increase extraordinarily in the big data setting, which perplexes the training procedure. Third, the lack of labeled data hinders the improvement of the model performance. To address these difficulties, we utilize online sketching hashing (OSH) and present a FasteR Online Sketching Hashing (FROSH) algorithm to sketch the data in a more compact form via an independent transformation. We provide theoretical justification to guarantee that our proposed FROSH consumes less time and achieves a comparable sketching precision under the same memory cost of OSH. We also extend FROSH to its distributed implementation, namely DFROSH, to further reduce the training time cost of FROSH while deriving the theoretical bound of the sketching precision. Finally, we conduct extensive experiments on both synthetic and real datasets to demonstrate the attractive merits of FROSH and DFROSH.

description: This volume covers Leg 83 of the cruises of the Drilling Vessel Glomar Challenger. During Leg 83 of the Deep Sea Drilling Project (DSDP), the Glomar Challenger devoted nearly two months to the most successful basement hole in the oceanic crust, Hole 504B. Located in 5.9 m.y. old crust about 200 km south of the spreading axis of the Costa Rica Rift, Hole 504B had been cored to a depth of 836 m beneath the seafloor during Legs 69 and 70 in late 1979. Thus, Leg 83 scientists approached Hole 504B with the unique opportunity to pioneer in the direct sampling of and experimentation within the deeper oceanic basement. In a broad sense, the main reason for the return to Hole 504B on Leg 83 was to extend our knowledge of the nature of the oceanic crust to the zone underlying the interlayered basaltic pillow-lava flow formation previously encountered in every basement hole cored by DSDP. Hole 504B was doubly interesting, in that it was cored in relatively young crust, capped by a thick sediment layer (274.5 m). Thus it provided the opportunity to study the in situ state of young oceanic crust, with particular focus on the petrological, geochemical, and physical signature of hydrothermal circulation in the porous, igneous basement near a spreading center. Leg 83 was specifically planned to deepen Hole 504B to sample and conduct geophysical experiments in the lower levels of Layer 2. Specific objectives of the studies of recovered samples included: 1. Determination of the lithostratigraphy and structure of the lower portion of Layer 2. 2. Determination of the geochemical nature of the recovered basalts. 3. Study of the alteration mineralogy and geochemistry and its variation with depth. 4. Measurement of various physical properties of recovered basalts. Leg 83 commenced on 14 November 1981 at Balboa Harbor, Panama, and terminated on 5 January 1982, again at Balboa Harbor.

description: Owing to the Hallyu wave's extensive global influence, this study investigates the extent of K-drama's influence on viewers' purchase intentions of Korean food. The study was conducted by surveying 110 college students in the National Capital Region in the Philippines. These students were selected as respondents because of their exposure to K-dramas and the availability of Korean food in the area. The results were analyzed using descriptive statistics and were evaluated using Elmo Lewis' AIDA Model. The success of the study depended on the use of various nominal extents, including consumption, preference, and purchase intention of Korean food. Based on the evidence from the reviews and data collected, this study demonstrates the consumption of Korean food among viewers is positively influenced by K-dramas on Netflix. It argues that the likelihood of purchasing Korean food products is significantly correlated with how frequently people watch Korean dramas. Hence, this research makes a strong case for the influence of the Hallyu wave and the contribution of K-dramas to the promotion of Korean food consumption.

description: The effect of surface degradation of the thermolectric cobaltite on Raman spectra is discussed and compared to experimental results from Co3O4 single crystals. We conclude that on NaCl flux grown NaxCoO2 crystals a surface layer of Co3O4 easily forms that leads to the observation of an intense phonon around 700 cm-1 [Phys. Rev. B 70, 052502 (2004)]. Raman spectra on freshly cleaved crystals from optical floating zone ovens do not show such effects and have a high frequency phonon cut-off at approximately 600 cm -1 [Phys. Rev. Lett 96, 167204 (2006)]. We discuss the relation of structural dimensionality, electronic correlations and the high frequency phonon cut-off of the thermolectric cobaltite.

SSHRC IDG awarded 2023: Two years ago our team undertook a small “side” project exploring the experience of grief among the Iranian­Canadian community in Edmonton in the aftermath of the Ukrainian Flight 752 tragedy that took the life of 176 passengers, and affected the Edmonton community disproportionately. Many participants in the project felt a deep sense of identification with the victims to the point of vividly imagining being on the airplane, being hit by missiles and dying. They reported significant mental health impacts from this mediated experience of death. They also reported significant changes in their sense of ethno­national identity. We propose to undertake a study of four distinct recent immigrant groups that have experienced significant war and violence firsthand or vicariously 'back home': people of Iranian, Ukrainian, Syrian, and Afghan origins.

description: Hardware technological advances are struggling to match scientific ambition, and a key question is how we can use the transistors that we already have more effectively. This is especially true for HPC, where the tendency is often to throw computation at a problem whereas codes themselves are commonly bound, at-least to some extent, by other factors. By redesigning an algorithm and moving from a Von Neumann to dataflow style, then potentially there is more opportunity to address these bottlenecks on reconfigurable architectures, compared to more general-purpose architectures. In this paper we explore the porting of Nekbone's AX kernel, a widely popular HPC mini-app, to FPGAs using High Level Synthesis via Vitis. Whilst computation is an important part of this code, it is also memory bound on CPUs, and a key question is whether one can ameliorate this by leveraging FPGAs. We first explore optimisation strategies for obtaining good performance, with over a 4000 times runtime difference between the first and final version of our kernel on FPGAs. Subsequently, performance and power efficiency of our approach on an Alveo U280 are compared against a 24 core Xeon Platinum CPU and NVIDIA V100 GPU, with the FPGA outperforming the CPU by around four times, achieving almost three quarters the GPU performance, and significantly more power efficient than both. The result of this work is a comparison and set of techniques that both apply to Nekbone on FPGAs specifically and are also of interest more widely in accelerating HPC codes on reconfigurable architectures.
