description: We show that a VMD based theoretical input allows for a significantly improved accuracy for the hadronic vacuum polarization of the photon which contributes to the theoretical estimate of the muon g-2. We also show that the only experimental piece of information in the $τ$ decay which cannot be accounted for is the accepted value for ${\rm Br}(τ\ra ππν_τ)$, while the spectum lineshape is in agreement with expectations from $e^+ e^-$ annihilations.

description: The treatment of wide-neck bifurcation cerebral aneurysms is challenging especially if at least one of the arteries arise from an obtuse angle. These wide-neck bifurcation aneurysms are difficult to treat with the usual balloon and stent assisted coiling, including Y stenting or double-barrel stent techniques [1, 2 ]. Other available options include using current devices with the waffle cone or double waffle cone techniques [3, 4 ]. Novel devices that are in development include intrasaccular devices and the barrel bifurcation vascular reconstruction device (Covidien) [5, 6, 7 ]. We report the use of a novel barrel technique using the LVIS (low-profile visualized intraluminal support) Jr stent for the treatment of a wide-neck bifurcation aneurysm.

description: We investigated the effects of different types of smiles on the perception of uncooperative or untrustworthy behaviour. In five studies, participants assigned to one group played an economic game with a representative of another group. In an initial round, the representative acted uncooperatively by favouring their group and then displayed a dominance, reward, or affiliation smile. Participants rated the motives of the representative and played a second round of the game with a different member of the same outgroup. Following uncooperative or untrustworthy behaviour, affiliation smiles communicated less positivity and superiority, and a greater desire to both repair the relationship between groups and change the uncooperative decision than reward or dominance smiles. Perceptions of a desire to repair the relationship and to change the decision were associated with trust and cooperation in a subsequent round of the game. Together, these findings show that smiles that are subtly different in their morphology can convey different messages and highlight the importance of these expressions in influencing the perceptions of others’ intentions.

description: This study presents a new direct solar floor heating technique with double heating network wich allows simultaneous use of solar and supply energy. Its main purpose is to store and to diffuse the whole available solar energy while regulating supply energy by physical means without using computer controlled technology. This solar system has been tested in real user conditions inside a bioclimatic house to study the interaction of non-inertial and passive walls on the solar productivity. Daily, monthly and annual energy balances were drawn up over three years and completed by real-time measurements of several physical on-site parameters. As a result the expected properties of this technique were improved. The use of per-hour solar productivity, saved primary energy and corrected solar covering ratio is recommended to analyze the performances of this plant and to allow more refined comparisons with other solar systems

description: In this study, we extended a model of the relations among ADHD symptoms, anxiety, and academic performance. Undergraduates (N = 515) completed self-report measures of anxiety (i.e. trait, test, math, and literacy) and ADHD symptoms. During the study, they completed math and literacy measures and reported their current (i.e. state) anxiety three times. There were significant correlations among ADHD symptoms and all measures of anxiety. However, neither ADHD symptoms nor trait anxiety were correlated with math or literacy performance. Test-anxious students reported increasing state anxiety as the study progressed. In contrast, math-anxious students reported increased state anxiety following the math tasks but not the literacy tasks and literacy-anxious students reported increased state anxiety following the literacy tasks but not the math tasks. With respect to performance, math-anxious students had worse math performance and literacy-anxious students had worse literacy performance whereas test anxiety was not directly related to performance on either math or literacy tasks. Patterns of relations did not differ for men and women, but, except for literacy anxiety, women reported higher levels of all types of anxiety. These results could help educators understand how affective responses are related to university students’ academic performance.

description: The rounding of first order phase transitions by quenched randomness is stated in a form which is applicable to both classical and quantum systems: The free energy, as well as the ground state energy, of a spin system on a $d$-dimensional lattice is continuously differentiable with respect to any parameter in the Hamiltonian to which some randomness has been added when $d \leq 2$. This implies absence of jumps in the associated order parameter, e.g., the magnetization in case of a random magnetic field. A similar result applies in cases of continuous symmetry breaking for $d \leq 4$. Some questions concerning the behavior of related order parameters in such random systems are discussed.

description: Cognitive theories of social anxiety implicate greater attention to negative social information in the development and maintenance of heightened social anxiety. Empirical evidence for this proposal, however, has been inconsistent. The aim of the current study was to examine the role of attentional control, which is one’s ability to deploy attention to goal-relevant information as a potential moderator of the association between selective attentional responding to negative social information and social anxiety. Eighty-nine adults were recruited through Mechanical Turk platform and completed the Social Interaction Anxiety Scale as well as a novel paradigm designed to measure selective attentional responding to negative social information (angry faces) and attentional control. Attentional control was operationalised as the capacity to direct attention to the specified target stimuli. The results supported the hypothesis that attentional control plays this moderating role. Specifically, while participants with low levels of attentional control exhibited a positive association between social anxiety and selective attentional responding to negative social information, this association was eliminated among participants with high levels of attentional control. This finding may explain the heterogeneity of research findings in this area. Implications, limitations and directions for future research are discussed.
Worked to the bone : skeletal activity patterns and their implications for daily life practices during the Shang dynasty, China
Creators: name: Osing, Natasha Kristine
Publisher: name: University of British Columbia
Year: 2023

description: Activity markers are often highly critiqued for their usage in bioarchaeological studies due to the multi-etiological nature of bone modifications. Simultaneously, other archaeological materials and methodology tend to overshadow bioarchaeological approaches, especially at Yinxu (modern-day Anyang, China), the last capital of the Shang dynasty (ca. 1200-1046 BC). More so, few bioarchaeological studies at Yinxu tend to focus solely on health-related issues among the commoner population. Despite their limitations, activity markers offer an avenue to expose activity patterns within the population that can lead to the understanding of labour organization and daily life practices. This study focuses on three types of activity markers, directional asymmetry, lower leg facets and imprints, and entheseal changes, to better understand how the body has adapted to the repetitive movements of the Shang to provide insight into their daily activities. The data for this project was collected in Anyang, China, from three collections: Xin’anzhuang, Dasikongcun and Xiaomintun, totalling 177 individuals. Each chapter within this dissertation focuses on specific activity markers and utilizes different methodologies. Three key findings were presented in this project. Firstly, directional asymmetry demonstrated that females tend to have larger left arms than their rights and vice versa for males. This stark difference was noticed across the landscape and was not neighbourhood-specific. Secondly, the facets and imprints study proved that Shang people utilized symmetrical squatting and kneeling positions consistently in their daily lives due to the appearance of multiple lower leg bony modifications. More so, it is impossible to differentiate between the two movements; therefore, discussing them in conjunction is necessary. Third, the entheseal change study revealed a statistically significant difference between the sexes and neighbourhoods, suggesting an activity-based organizational difference throughout the landscape that may likely be based on craft production. These findings demonstrate the need to incorporate bioarchaeological methodology in ancient studies, especially at Yinxu. Analysis from skeletal bodies can expose patterns of daily life unobtainable from other archaeological material alone. When utilized collectively with other sub-disciplinary methodologies, a more extensive understanding of the inner workings of Shang society can present itself.

description: Episodes with an emotional component preoccupy memory formation and this advantage facilitates their preservation and mitigates the impact of interfering episodes. The present study examined the relation of the emotional dimensions of original and interfering episodes to the memory outcome, using a reconsolidation paradigm. In a between-subjects design, 102 healthy young adults were presented with an emotional or neutral image and learned either an emotional or neutral story, respectively (day 1). On day 2, experimental groups were presented with an image of the opposite emotionality, reactivated the original story, and learned a story of the opposite emotionality. On day 3, experimental and control groups were tested for their memory on target and filler clues of the original story and rated both stories for arousal and valence. Overall, there was evidence of interference on the long-term retention of target clues only for the neutral story (i.e. when the interfering story was emotional), and of filler clues for both types of stories. Moreover, individual target clue retention rates correlated with the arousal ratings for both the original neutral story and the interfering emotional story, while they were not related to arousal ratings for the original emotional story or the interfering neutral one.

description: Most numerical models of binary stars - in particular neutron stars in compact binaries - assume the companions to be either corotational or irrotational. Either one of these assumptions leads to a significant simplification in the hydrodynamic equations of stationary equilibrium. In this paper we develop a new formalism for the construction of binary stars with circulation intermediate between corotational and irrotational. Generalizing the equations for irrotational flow we cast the Euler equation, which is an algebraic equation in the case of corotational or irrotational fluid flow, as an elliptic equation for a new auxiliary quantity. We also suggest a parameterized decomposition of the fluid flow that allows for a variation of the stellar circulation.

Year: 2009
Subjects: subject: Networking and Internet Architecture (cs.NI)

description: In this research, we propose an architectural solution to implement the voice over IP (VoIP) service in campus environment network. Voice over IP (VoIP) technology has become a discussion issue for this time being. Today, the deployment of this technology on an organization truly can give a great financial benefit over traditional telephony. Therefore, this study is to analyze the VoIP Codec selection and investigate the Mean Opinion Score (MOS) performance areas evolved with the quality of service delivered by soft phone and IP phone. This study focuses on quality of voice prediction such as i) accuracy of MOS between automated system and human perception and ii) different types of codec performance measurement via human perception using MOS technique. In this study, network management system (NMS) is used to monitor and capture the performance of VoIP in campus environment. In addition, the most apparent of implementing soft phone and IP phone in campus environment is to define the best codec selection that can be used in operational environment. Based on the finding result, the MOS measurement through automated and manual system is able to predict and evaluate VoIP performance. In addition, based on manual MOS measurement, VoIP conversations over LAN contribute more reliability and availability performance compare to WAN.

Some resemble properties are found among most of the hypernuclei found in experiments. The data show that a $Λ$ hypernucleus will be more stable, if it is composed of a $Λ$ hyperon adding to a stable normal nuclear core, or a $Λ$ hyperon replacing a neutron in a stable normal nuclear core. According to our calculations, existences of some new $Λ$ hypernuclei are predicted under the frame of RMF.

description: Early behavioural inhibition, a temperamental characteristic defined by fearful, overly-sensitive, avoidant, or withdrawn reactions to the unknown, is a predictor of later social anxiety. However, not all behaviourally inhibited children develop anxiety problems, and attentional bias to threat has been proposed to moderate the relation between behavioural inhibition and anxiety. The current study aimed to further specify the relation between early behavioural inhibition and later social anxiety by testing this potentially moderating role of childhood attentional bias to threat. Behavioural inhibition was assessed during toddlerhood (age 2.5 years) using laboratory observations of children’s behaviours in response to unknown objects and situations. When children were 7.5 years old, attentional bias was measured in 86 children (46 girls) using both a visual probe task and a visual search task with angry and happy faces. Child social anxiety was measured using questionnaires completed by the child and both parents, and clinical interviews conducted with both parents. Our results showed that while early behavioural inhibition was related to later social anxiety, there was no evidence for a moderation of this relation by attentional bias, suggesting that the relation between early fearful temperament and later social anxiety holds across children, independent of their attentional biases.

In particular, we elaborate how to achieve the wanted operations to create and manipulate the topological quantum states, providing an experimentally feasible scenario to access the topological memory and to build the anyonic interferometry.

Early life history interactions of White Sturgeon (Acipenser transmontanus) with substrates and predaceous invertebrates
Creators: name: Fisher, Jennifer
Publisher: name: University of British Columbia
Year: 2023

description: White Sturgeon (Acipenser transmontanus) are from an ancient lineage and many of their populations are listed as endangered. Recruitment failure, a general term for a low or a lack of survival to sexual maturity, is the primary contributor to this endangerment. In the Nechako River of British Columbia, White Sturgeon embryos and yolk sac larvae are not surviving past their first month of life, despite successful spawning events taking place every year. Changes in benthic sediment composition because of flow regulation appear the likely cause of this lack of early life history success. However, it remains uncertain precisely in what way which these events have impacted these early life stages, and what the most important factors are for survival in the first month of life of White Sturgeon. Few studies have examined yolk sac larvae (YSL), and even fewer have studied embryos. No studies have thus far examined the interaction between predaceous stonefly nymphs and early life stage White Sturgeon, despite them being found in the same environments. I investigated how different substrate sizes act in conjunction with invertebrate predators to influence the early life history success of White Sturgeon embryos and larvae. I also tested how sand-coating impacts embryos. I discuss three experiments, each addressing different aspects of these interactions. I found no evidence that predatory stonefly nymphs consume White Sturgeon embryos, nor that their presence and sand coating are good predictors of embryo survival to hatch. However, I did find that there was a significant effect of invertebrate presence on hatch timing, shifting hatch timing slightly later. I found that the condition factor of YSL reared over sand was significantly lower than that of YSL reared over coarse gravel. However, substrate size did not influence the vulnerability of YSL to predation by predatory stonefly nymphs. I also found that substrate size had a significant impact on time to emergence for larvae, but that invertebrate presence did not. Overall, I found that predatory stonefly nymphs did not appear to prey White Sturgeon embryos, that they lowered survivorship of larvae, and that coarser substrate led to increased condition factor.

description: Recently, Yin et al. [Eur. Phys. J. B 49, 205 (2006)] introduced an efficient small-world network traffic model using preferential next-nearest neighbor routing strategy with the so-called path iteration avoidance (PIA) rule to study the jamming transition of internet. Here we study their model without PIA rule by a mean-field analysis which carefully divides the message packets into two types. Then, we argue that our mean-field analysis is also applicable in the presence of PIA rule in the limit of a large number of nodes in the network. Our analysis gives an explicit expression of the critical packet injection rate $R_c$ as a function of a bias parameter of the routing strategy $α$ in their model with or without PIA rule. In particular, we predict a sudden change in $R_c$ at a certain value of $α$. These predictions agree quite well with our extensive computer simulations.

description: Pulsar timing arrays (PTAs) are designed to detect gravitational waves with periods from several months to several years, e.g. those produced by by wide supermassive black-hole binaries in the centers of distant galaxies. Here we show that PTAs are also sensitive to mergers of supermassive black holes. While these mergers occur on a timescale too short to be resolvable by a PTA, they generate a change of metric due to non-linear gravitational-wave memory which persists for the duration of the experiment and could be detected. We develop the theory of the single-source detection by PTAs, and derive the sensitivity of PTAs to the gravitational-wave memory jumps. We show that mergers of $10^8M_{\odot}$ black holes are $2-σ$-detectable (in a direction, polarization, and time-dependent way) out to co-moving distances of $\sim 1$ billion light years. Modern prediction for black-hole merger rates imply marginal to modest chance of an individual jump detection by currently developed PTAs. The sensitivity is expected to be somewhat higher for futuristic PTA experiments with SKA.

description: Magnetoresistance of two-dimensional electron systems with several occupied subbands oscillates owing to periodic modulation of the probability of intersubband transitions by the quantizing magnetic field. In addition to previous investigations of these magneto-intersubband (MIS) oscillations in two-subband systems, we report on both experimental and theoretical studies of such a phenomenon in three-subband systems realized in triple quantum wells. We show that the presence of more than two subbands leads to a qualitatively different MIS oscillation picture, described as a superposition of several oscillating contributions. Under a continuous microwave irradiation, the magnetoresistance of triple-well systems exhibits an interference of MIS oscillations and microwaveinduced resistance oscillations. The theory explaining these phenomena is presented in the general form, valid for an arbitrary number of subbands. A comparison of theory and experiment allows us to extract temperature dependence of quantum lifetime of electrons and to confirm the applicability of the inelastic mechanism of microwave photoresistance for the description of magnetotransport in multilayer systems.

description: Flow-induced aggregation of colloidal particles leads to aggregates with fairly high fractal dimension () which are directly responsible for the observed rheological properties of sheared dispersions. We address the problem of the decrease of aggregate size with increasing hydrodynamic stress, as a consequence of breakup, by means of a fracture-mechanics model complemented by experiments in a multi-pass extensional (laminar) flow device. Evidence is shown that as long as the inner density decay with linear size within the aggregate (due to fractality) is not negligible (as for), this imposes a substantial limitation to the hydrodynamic fragmentation process as compared with non-fractal aggregates (where the critical stress is practically size-independent). This is due to the fact that breaking up a fractal object leads to denser fractals which better withstand stress. In turbulent flows, accounting for intermittency introduces just a small deviation with respect to the laminar case, while the model predictions are equally in good agreement with experiments from the literature. Our findings are summarized in a diagram for the breakup exponent (governing the size versus stress scaling) as a function of fractal dimension.

description: The distribution of entangled states of light over long distances is a major challenge in the field of quantum information. Optical losses, phase diffusion and mixing with thermal states lead to decoherence and destroy the non-classical states after some finite transmission-line length. Quantum repeater protocols, which combine quantum memory, entanglement distillation and entanglement swapping, were proposed to overcome this problem. Here we report on the experimental demonstration of entanglement distillation in the continuous-variable regime. Entangled states were first disturbed by random phase fluctuations and then distilled and purified using interference on beam splitters and homodyne detection. Measurements of covariance matrices clearly indicate a regained strength of entanglement and purity of the distilled states. In contrast to previous demonstrations of entanglement distillation in the complementary discrete-variable regime, our scheme achieved the actual preparation of the distilled states, which might therefore be used to improve the quality of downstream applications such as quantum teleportation.

description: We obtain an implicit equation for the correlation dimension of dynamical systems in terms of an integral over a propagator. We illustrate the utility of this approach by evaluating the correlation dimension for inertial particles suspended in a random flow. In the limit where the correlation time of the flow field approaches zero, taking the short-time limit of the propagator enables the correlation dimension to be determined from the solution of a partial differential equation. We develop the solution as a power series in a dimensionless parameter which represents the strength of inertial effects.

Towards scalable and efficient program compilation for emerging computing platforms
Creators: name: Chen, Yanhao
Publisher: name: No Publisher Supplied
Year: 2023

description: Recently, there has been a growing interest in modern technologies such as Artificial Intelligence (AI), Machine Learning (ML), and Large Language Models (LLM). Applications in these areas often require a substantial amount of computing power. To fulfill this demand, new computing platforms are being developed. These platforms are carefully designed to handle complex computing needs and have a high level of computing power. Program compilation is the process of translating a program written in a high-level programming language into a low-level language that can be executed by a computing platform. This is an essential step in program development on any computing platform. As those emerging computing platforms offer new capabilities and performance advantages over traditional ones, they also present new challenges for optimizing the corresponding program compilation process. This thesis explores various program compilation optimization techniques for cutting edge computing platforms. We especially concentrate on two important computing areas, GPU parallel computing and quantum computing. In the first part of the thesis, we delve into the context of single GPU parallel computing. We discuss the cache thrashing problem for sparse matrix operations on a single GPU. Specifically, we present a new software throttling framework that makes use of graph edge partitioning to better display the data’s locality. We also demonstrate a heap-based priority queue implementation on a single GPU that can be used to solve a variety of graph problems, including shortest path, minimum spanning tree, and 0/1 knapsack problems. The second part of this thesis investigates optimizing program compilation for quantum computing. We introduce a pulse generation framework that incorporates graph representations of quantum circuits to optimize pulse generation in quantum computing. By modeling dependencies between quantum gates as a graph, the framework dynamically selects program-aware basis gates and applies criticality analysis to identify and prioritize critical regions. This graph-based approach enhances the accuracy and efficiency of pulse generation and improves overall program fidelity. Throughout the thesis, various optimization methodologies are presented to demonstrate their effectiveness and efficiency in improving the compilation process.

description: The Enhanced Critical Incident Technique (ECIT) is a qualitative methodology that has been widely used within the fields of organizational and industrial psychology to help identify critical incidents, events, or factors that help or hinder the successful performance of an event, activity, or experience (Butterfield et al., 2005; 2009). Utilizing the ECIT, the current study aimed to (a) explore the factors present within teacher preparation programs that have helped or hindered early-career teachers' abilities to support the social and emotional development of their students, through the use of social and emotional learning (SEL) programs and practices, and (b) generate a wish-list of SEL promoting factors that early-career teachers wish they had received as part of their teacher preparation. Data were collected using semi-structured interviews guided by ECIT protocol. The sample included 11 early-career teachers (5 years, or less, of teaching experience) recruited in Oregon, a state in the Pacific Northwest region of the United States. All participants were currently employed as K-12 teachers and had graduated from an accredited teacher preparation program in Oregon between 2017-2021. This study was completed towards the end of the height of the COVID-19 pandemic; initial interviews were conducted between August – October 2022 and follow-up sessions concluded in January 2023. Analyses identified 181 factors related to participants’ teacher preparation programs that they felt had critically impacted their abilities to support the SEL and the social and emotional development of their students. Of these 181 factors, 74 were categorized as helpful, 43 as hindering or unhelpful, and 64 as wish-list items. Utilizing an iterative data analysis process, four primary categories were created to represent prominent themes: (a) Curriculum and Course Content, (b) Programmatic Elements, (c) Experience in Educational Settings, and (d) Modeling Social, Emotional, and Cultural Competence. Based on these findings, the results of this study were utilized to synthesize recommendations for educational leaders in Oregon who are currently working to integrate SEL-based teaching standards into teacher preparation programs across Oregon. Implications of findings, strengths and limitations of this study, and recommendations to inform future research are discussed.

Beim erwachsenen Stück ist die hintere Mandibelgegend ausserordentlich angeschwollen, prall und von tief kirschrother Färbung. Achselhöhlen mit feinen Körnern ausgekleidet. Beim jungen Stück sind die Kämme über dem Trommelfell und auf dem Rücken sehr schwach ausgebildet, ebenso sind die gegenseitigen Grössenverhältnisse der Rücken- und der Schwanzschuppen viel weniger ausgesprochen; die Art ist aber auch hier kenntlich an den grossen, starkgekielten, grüngelb und schwarz gefärbten Kehlschuppen.

description: We study numerically some possible vortex configurations in a rotating cylinder that is tilted with respect to the rotation axis and where different numbers of vortices can be present at given rotation velocity. In a long cylinder at small tilt angles the vortices tend to align along the cylinder axis and not along the rotation axis. We also show that the axial flow along the cylinder axis, caused by the tilt, will result in the Ostermeier-Glaberson instability above some critical tilt angle. When the vortices become unstable the final state often appears to be a dynamical steady state, which may contain turbulent regions where new vortices are constantly created. These new vortices push other vortices in regions with laminar flow towards the top and bottom ends of the cylinder where they finally annihilate. Experimentally the inclined cylinder could be a convenient environment to create long lasting turbulence with a polarization which can be adjusted with the tilt angle.

description: We prove a limit relation for the Dunkl-Bessel function of type $B_N$ with multiplicity parameters $k_1$ on the roots $\pm e_i$ and $k_2$ on $\pm e_i\pm e_j$ where $k_1$ tends to infinity and the arguments are suitably scaled. It gives a good approximation in terms of the Dunkl-type Bessel function of type $A_{N-1}$ with multiplicity $k_2$. For certain values of $k_2$ an improved estimate is obtained from a corresponding limit relation for Bessel functions on matrix cones.

description: Based on experimental crystallographic data, electronic structure of UGe$_2$ have been calculated and compared with our results of X-ray photoelectron spectroscopy (XPS) measurements. We employed two different advanced full potential (FP) methods: FP-local-orbital (FPLO) and FP-linear augmented plane waves (Wien2k) codes for non-magnetic and ferromagnetic states. Starting from the local spin-density approximation (LSDA) or generalised gradient approximation (GGA), we verified either the orbital polarisation (OP) correction or the GGA+U approach for the U 5f-electrons, changing Coulomb-repulsion energies U in the range 0-4 eV. Satisfying agreement was achieved between experimental and our calculated magnetic moments using ab-initio LSDA+OP and non-ab-initio GGA+U approaches, the latter for realistic U values of 2-3 eV. We proved by the LSDA+OP approach an existence of the Fermi surface nesting vector along the a axis, possibly responsible for the triplet superconducting pairing. The calculated data reveal predominantly an itinerant U 5f-electron character of bands near the Fermi level, EF, with only small contributions from the U 6d and Ge 4p states. The experimental XPS spectrum of valence bands (VB) also contains the sharp main 5f-electron peak at EF, a wide hump (around -2 eV), and broad small peaks at higher energies. In the calculated XPS spectrum, the width of the main 5f-electron peak varies between 0.8 and 1.4 eV, depending on a method used in computations, but the hump remains unresolved. A newly observed asymmetric 1-eV satellite in the experimental 4f-core XPS spectrum together with known 3-eV and 7-eV satellites suggest dual behaviour of U-5f-electrons in UGe$_2$, the feature is inferred also from the VB studies.
