description: In this paper, disturbance reconstruction and robust trajectory tracking control of biped robots with hybrid dynamics in the port-Hamiltonian form is investigated. A new type of Hamiltonian function is introduced, which ensures the finite-time stability of the closed-loop system. The proposed control system consists of two loops: an inner and an outer loop. A fractional proportional-integral-derivative filter is used to achieve finite-time convergence for position tracking errors at the outer loop. A fractional-order sliding mode controller acts as a centralized controller at the inner-loop, ensuring the finite-time stability of the velocity tracking error. In this loop, the undesired effects of unknown external disturbance and parameter uncertainties are compensated using estimators. Two disturbance estimators are envisioned. The former is designed using fractional calculus. The latter is an adaptive estimator, and it is constructed using the general dynamic of biped robots. Stability analysis shows that the closed-loop system is finite-time stable in both contact-less and impact phases. Simulation studies on two types of biped robots (i.e., two-link walker and RABBIT biped robot) demonstrate the proposed controller's tracking performance and disturbance rejection capability.

description: We study the process of the association production of chargino and neutralino including the NLO QCD and the complete one-loop electroweak corrections in the framework of the minimal supersymmetric standard model(MSSM) at the Fermilab Tevatron and the CERN Large Hadron Collider (LHC). In both the NLO QCD and one-loop electroweak calculations we apply the algorithm of the phase-space slicing(PSS) method. We find that the NLO QCD corrections generally increase the Born cross sections, while the electroweak relative corrections decrease the Born cross section in most of the chosen parameter space. The NLO QCD and electroweak relative corrections typically have the values of about 32% and -8% at the Tevatron, and about 42% and -6% at the LHC respectively. The results show that both the NLO QCD and the complete one-loop electroweak corrections to the processes $p \bar p/pp \to \widetildeχ_1^{\pm} \widetildeχ_2^0+X$ are generally significant and should be taken into consideration in precision experimental analysis.

description: We present a theory for quantum impurity relaxometry of magnons in thin films, exhibiting quantitative agreement with recent experiments without needing arbitrary scale factors used in theoretical models thus far. Our theory reveals that chiral coupling between prototypical spin>1/2 quantum impurities and magnons plays a central role in determining impurity relaxation, which is further corroborated by our experiments on nickel films interfaced with nitrogen-vacancy centers. Along with advancing magnonics and understanding decoherence in hybrid quantum platforms with magnets, the ability of a quantum impurity spin to sense chiral magnetic noise presents an opportunity to probe chiral phenomena in condensed matter.

Assembling the puzzle : an investigation of Asian adolescent students’ recreational reading habits

description: My belief in the value of recreational reading for pleasure prompted this study which was designed to understand the educational and cultural background of Asian adolescent students and make recommendations so that we can ensure that all students in our English classrooms are equipped with the skills and motivation to read for pleasure and thus are able to participate fully in class regardless of their previous educational experience. In the study I investigated the recreational reading habits of Asian adolescents in two similar urban schools in Vancouver to discover why Asian adolescents were not reading recreation ally in English. I examined the participants recollections of their experiences with books and story from birth to preschool, in kindergarten and elementary school in Hong Kong, Taiwan, and Communist China. I used interviews to gather data from 22 Asian adolescents, 5 English as a second language (ESL) adults, 8 teachers of ESL and 100 recently arrived ESL parents in the Vancouver area. Results indicated that many of the students perceived reading only as a means of improving their English skills and increasing their knowledge base. Adolescents coming to Canada face many pressures to learn English quickly and graduate "on time." Their experiences with literature in their home country were very different from the expectations of Vancouver schools and the expectations of the home culture and parents expect adolescents to study hard. I conclude with recommendations to all groups involved in education to encourage Asian adolescent students of ESL background to read recreationally in English.

description: There is a deep connection between the ground states of transverse-field spin systems and the late-time distributions of evolving viral populations -- within simple models, both are obtained from the principal eigenvector of the same matrix. However, that vector is the wavefunction amplitude in the quantum spin model, whereas it is the probability itself in the population model. We show that this seemingly minor difference has significant consequences: phase transitions which are discontinuous in the spin system become continuous when viewed through the population perspective, and transitions which are continuous become governed by new critical exponents. We introduce a more general class of models which encompasses both cases, and that can be solved exactly in a mean-field limit. Numerical results are also presented for a number of one-dimensional chains with power-law interactions. We see that well-worn spin models of quantum statistical mechanics can contain unexpected new physics and insights when treated as population-dynamical models and beyond, motivating further studies.

description: Let $f(x)$ and $g(x)$ be two real polynomials whose leading coefficients have the same sign. Suppose that $f(x)$ and $g(x)$ have only real zeros and that $g$ interlaces $f$ or $g$ alternates left of $f$. We show that if $ad\ge bc$ then the polynomial $$(bx+a)f(x)+(dx+c)g(x)$$ has only real zeros. Applications are related to certain results of F.Brenti (Mem. Amer. Math. Soc. 413 (1989)) and transformations of Pólya frequency sequences. More specifically, suppose that $A(n,k)$ are nonnegative numbers which satisfy the recurrence $$A(n,k)=(rn+sk+t)A(n-1,k-1)+(an+bk+c)A(n-1,k)$$ for $n\ge 1$ and $0\le k\le n$, where $A(n,k)=0$ unless $0\le k\le n$. We show that if $rb\ge as$ and $(r+s+t)b\ge (a+c)s$, then for each $n\ge 0$, $A(n,0),A(n,1),...,A(n,n)$ is a Pólya frequency sequence. This gives a unified proof of the PF property of many well-known sequences including the binomial coefficients, the Stirling numbers of two kinds and the Eulerian numbers.

description: We analytically study electronic bound states around a single vortex core in a noncentrosymmetric superconductor such as ${\rm CePt_3Si}$ without mirror symmetry about the $ab$ plane. Considering a mixed spin-singlet-triplet Cooper pairing model, we obtain a formula about the local density of states (LDOS) around a vortex core in any directions of magnetic fields. The LDOS under a magnetic field perpendicular to the c axis are quite different from those of typical s-wave or d-wave superconductors. From the ellipticity of the spatial pattern of the LDOS around a vortex core, one can estimate experimentally the pairing symmetry of ${\rm CePt_3Si}$ such as the position of the gap nodes and the ratio of the singlet component to the triplet component in order parameter.

Background/Aims: The aim of this study was to apply the European Society for Clinical Nutrition and Metabolism/European Association for the Study of Obesity (ESPEN/EASO) consensus to identify sarcopenic obesity (SO) in adults mid to long-term post-Roux-en-Y gastric bypass (RYGB) using both dual-energy x-ray absorptiometry (DXA) and bioelectrical impedance analysis (BIA). Further, this approach was compared to accepted sarcopenia diagnostic criteria (Revised European Working Group on Sarcopenia in Older People [EWGSOP2] and Sarcopenia Definition and Outcomes Consortium [SDOC]).

Methods: This cross-sectional study included adults ≥2 years post-RYGB surgery. Obesity was diagnosed by excess fat mass (FM) for all diagnostic criteria. Agreement was evaluated using Cohen’s Kappa.

Results: We evaluated 186 participants (90.9% female, median age 43.9 years, 6.8 years post-surgery), of which 60.2% (BIA), and 83.3% (DXA) had excess FM. Low muscle strength was not identified using absolute handgrip strength. The prevalence of SO by BIA or DXA, respectively, was 7.9% (95%CI 3.9-12.5), and 23.0% (95%CI 17.1-30.3) [ESPEN/EASO SO consensus]; 0.7% (95%CI 0-2.0), and 3.3% (95%CI 0.7- 5.9) [EWGSOP2]; and 27.0% (95%CI 19.7-34.2), and 30.3% (95%CI 23.0-37.5) [SDOC]. Agreement between the ESPEN/EASO SO consensus and other diagnostic criteria was none to slight using DXA: EWGSOP2 k=0.19; 95% CI 0.04-0.34, or SDOC k=0.16; 95% CI -0.01-0.32. Moderate agreement was observed within the ESPEN/EASO SO consensus for BIA and DXA (k=0.43; 95% CI 0.26-0.60).

Conclusions: This is the first study to explore the prevalence of SO using the ESPEN/EASO criteria. We identified a high but variable prevalence of SO in postbariatric surgery patients (7.9-23.0%), depending on the body composition technique used; prevalence was higher using DXA. Little agreement was observed for the diagnosis of SO using the three diagnostic criteria. Future studies are needed to explore the relationship between SO identified by the ESPEN/EASO consensus and health status/outcomes.
An exploration of diversity in the adult basic education literacy classroom

description: A narrative inquiry study was conducted to explore the educational experiences and perceptions of literacy of a small group of adult literacy learners from various language backgrounds. The purpose of the study was to identify the common experiences of this representative group of adult literacy learners in order to explore some implications for practice in the literacy classroom. The four groups represented included: (a) Canadian born whose only language is English, (b) immigrant from a country where English is the official language, but it is nonstandard English, (c) EASL immigrant, and (d) Canadian born, but whose initial language acquisition was in a language other than English. The questions for the study were developed through input from members of the Provincial Fundamental Articulation Committee and Academic and Career Preparation English faculty from the institution where the study was conducted. In addition, a pilot study was conducted to further refine the questions for the study prior to the actual study. The study was conducted over a five month period, with the subjects chosen from the researcher's classroom. A number of common themes were identified. Previous school experience had been a struggle, and didn't meet the literacy skill expectations of the subjects. All were comfortable with their native spoken language, but all reported problems with reading or writing. Although, everyone saw reading as gaining meaning from print, primarily passive strategies for meaning acquisition were reported. A supportive environment was identified as important for optimum learning to occur. All had a pragmatic approach to learning. All learned best by doing. Improved literacy skills were perceived as necessary for improved employment opportunities and a better life. The implications for instruction identified by the researcher included awareness of the learning gaps that may have hindered the subjects' acquisition of literacy skills (including mastery of basic English decoding), a metacognitive approach to learning, a caring sensitive, flexible instructor, and a supportive learning environment.

description: Compound eyes found in insects provide intriguing sources of biological inspiration for miniaturized imaging systems. Inspired by such insect eye structures, we demonstrate an ultrathin arrayed camera enabled by a flat multilevel diffractive microlens array for super-resolution visible imaging. We experimentally demonstrated that the microlens array can achieve large fill factor (hexagonal close packing with pitch=120um), thickness of 2.6um, and diffraction-limited (strehl ratio = 0.88) achromatic performance in the visible band (450nm to 650nm). We also demonstrate super-resolution imaging with resolution improvement of 1.4 times by computationally merging 1600 images in the array.

description: We present a spectroscopic survey of Ly$α$ emitters (LAEs) at $z\approx5.7$ using the multi-object spectrograph M2FS on the Magellan Clay telescope. This is part of a high-redshift galaxy survey carried out in several well-studied deep fields. These fields have deep images in multiple UV/optical bands, including a narrow NB816 band that has allowed an efficient selection of LAE candidates at $z\approx5.7$. Our sample consists of 260 LAEs and covers a total effective area of more than two square degrees on the sky. This is so far the largest (spectroscopically confirmed) sample of LAEs at this redshift. We use the secure redshifts and narrowband photometry to measure Ly$α$ luminosities. We find that these LAEs span a Ly$α$ luminosity range of $\sim 2\times10^{42} - 5\times10^{43}$ erg s$^{-1}$, and include some of the most luminous galaxies known at $z \ge 5.7$ in terms of Ly$α$ luminosity. Most of them have rest-frame equivalent widths between 20 and 300 Å, and more luminous Ly$α$ emission lines tend to have broader line widths. We detect a clear offset of $\sim20$ Å between the observed Ly$α$ wavelength distribution and the NB816 filter transmission curve, which can be explained by the intergalactic medium absorption of continua blueward of Ly$α$ in the high-redshift spectra. This sample is being used to study the Ly$α$ luminosity function and galaxy properties at $z\approx5.7$.

description: The use of lattice tensor representations is explored to investigate the lattice Landau gauge gluon propagator for the pure SU(3) Yang-Mills gauge theory in 4D. The analysis of several tensor bases allows to quantify the completeness of the various tensor bases considered, the deviations of the lattice results from the continuum theory due to the lattice artefacts and estimate the theoretical uncertainty in the propagator. Furthermore, our analysis tests continuum based relations with the lattice data and show that the lattice Landau gauge gluon propagator is described by a unique form factor, as in the continuum formulation.

description: Based on lattice simulations with two flavours of dynamical, O(a)-improved Wilson fermions we present results for the first two moments of the distribution amplitudes of pseudoscalar mesons at several values of the valence quark masses. By extrapolating our results to the physical masses of up/down and strange quarks, we find the first two moments of the K^+ distribution amplitude and the second moment of the pi^+ distribution amplitude. We use nonperturbatively determined renormalisation coefficients to obtain results in the MSbar scheme. At a scale of 4 GeV^2 we find a_2^pi=0.201(114) for the second Gegenbauer moment of the pion's distribution amplitude, while for the kaon, a_1^K=0.0453(9)(29) and a_2^K=0.175(18)(47).

description: A neuropathological hallmark of Parkinson’s disease (PD) is the cerebral deposition of abnormally aggregated α-synuclein (αSyn). PD-associated αSyn (αSynPD) aggregates are assumed to act, in a prion-like manner, as proteinaceous nuclei (“seeds”) capable of self-templated propagation. Braak and colleagues put forward the idea of a neural gut-brain axis mediating the centripetal spread of αSynPD pathology from the enteric nervous system (ENS) to the brain in PD. This has sparked great interest and initiated passionate discussions both in support of and opposing the suggested hypothesis. A precedent for the spread of protein seeds or seeding from the gastro-intestinal (GI) tract to the central nervous system (CNS) had been previously revealed for pathological prion protein in peroral prion infections. This article scrutinizes the similarities and dissimilarities between the pathophysiological spread of disease-associated protein aggregation along the neural gut–brain axis in peroral prion infections and PD. On this basis, evidence supporting the proposed neural gut–brain axis in PD is concluded to be not as robust as that established for peroral prion infections. New tools for the ultrasensitive detection of αSynPD-associated seeding activity in archived or fresh human tissue samples such as real-time quaking induced conversion (RT-QuIC) or protein misfolding cyclic amplification (PMCA) assays can possibly help to address this deficit in the future.

description: The GJ 436 planetary system is an extraordinary system. The Neptune-size planet that orbits the M3 dwarf revealed in the Ly$α$ line an extended neutral hydrogen atmosphere. This material fills a comet-like tail that obscures the stellar disc for more than 10 hours after the planetary transit. Here, we carry out a series of 3D radiation hydrodynamic simulations to model the interaction of the stellar wind with the escaping planetary atmosphere. With these models, we seek to reproduce the $\sim56\%$ absorption found in Ly$α$ transits, simultaneously with the lack of absorption in H$α$ transit. Varying the stellar wind strength and the EUV stellar luminosity, we search for a set of parameters that best fit the observational data. Based on Ly$α$ observations, we found a stellar wind velocity at the position of the planet to be around [250-460] km s$^{-1}$ with a temperature of $[3-4]\times10^5$ K. The stellar and planetary mass loss rates are found to be $2\times 10^{-15}$ M$_\odot$ yr$^{-1}$ and $\sim[6-10]\times10^9$ g s$^{-1}$, respectively, for a stellar EUV luminosity of $[0.8-1.6]\times10^{27}$ erg s$^{-1}$. For the parameters explored in our simulations, none of our models present any significant absorption in the H$α$ line in agreement with the observations.

A single-degenerate model for the progenitor of the Type Ia supernova 2002ic

description: Supernova 2002ic was an atypical Type Ia supernova (SN Ia) with evidence for substantial amounts of hydrogen associated with the system. Contrary to previous claims, we show that its unusual properties can be understood within the framework of one of the most favoured progenitor models, the so-called supersoft channel. This requires that the donor star was initially relatively massive ($\sim 3\Ms$) and that the system experienced a delayed dynamical instability, leading to a large amount of mass loss from the system in the last few $10^4 $yr before the explosion. This can produce the inferred hydrogen-rich circumstellar environment, most likely with a disc-like geometry. However, to apply these models requires a larger accretion efficiency onto the white dwarf than is assumed in present parameterizations. If this is confirmed, it would most likely increase estimates for the frequency of the single-degenerate channel. Based on population synthesis simulations we estimate that not more than 1 in 100 SNe Ia should belong to this subgroup of SNe Ia.

description: Genesis within the Horndeski theory is one of possible scenarios for the start of the Universe. In this model, the absence of instabilities is obtained at the expense of the property that coefficients, serving as effective Planck masses, vanish in the asymptotics $t\rightarrow -\infty$, which signalizes the danger of strong coupling and inconsistency of the classical treatment. We investigate this problem in a specific model and extend the analysis of cubic action for perturbations (arXiv:2003.01202) to arbitrary order. Our study is based on power counting and dimensional analysis of the higher order terms. We derive the latter, find characteristic strong coupling energy scales and obtain the conditions for the validity of the classical description. Curiously, we find that the strongest condition is the same as that obtained in already examined cubic case.
Constraining primordial black holes as dark matter using the global 21-cm signal with X-ray heating and excess radio background

description: Using the global 21-cm signal measurement by the EDGES collaboration, we derive constraints on the fraction of the dark matter that is in the form of primordial black holes (PBHs) with masses in the range $10^{15}$-$10^{17}\,$g. Improving upon previous analyses, we consider the effect of the X-ray heating of the intergalactic medium on these constraints, and also use the full shape of the 21-cm absorption feature in our inference. In order to account for the anomalously deep absorption amplitude, we also consider an excess radio background motivated by LWA1 and ARCADE2 observations. Because the heating rate induced by PBH evaporation evolves slowly, the data favour a scenario in which PBH-induced heating is accompanied by X-ray heating. Also, for the same reason, using the full measurement across the EDGES observation band yields much stronger constraints on PBHs than just the redshift of absorption. We find that 21-cm observations exclude $f_{\mathrm{PBH}} \gtrsim 10^{-9.7}$ at 95% CL for $M_{\mathrm{PBH}}=10^{15}\,$g. This limit weakens approximately as $M_{\mathrm{PBH}}^4$ towards higher masses, thus providing the strongest constraints on ultralight evaporating PBHs as dark matter over the entire mass range $10^{15}$-$10^{17}\,$g. Under the assumption of a simple spherical gravitational collapse based on the Press-Schechter formalism, we also derive bounds on the curvature power spectrum at extremely small scales ($k\sim 10^{15}\,$Mpc$^{-1}$). This highlights the usefulness of global 21-cm measurements, including non-detections, across wide frequency bands for probing exotic physical processes.

Amy's story: an examination of the reading process of a learning disabled student
Creators: name: Mehrassa, Ramin
Publisher: name: University of British Columbia
Year: 2009

description: This thesis describes a grade eleven female learning disabled student's perceptions of reading and their impact on her reading performance. A review of the literature provides a perspective on the nature of reading, as well as cognitive and affective factors influencing reading. The view that the reader's goal is to actively construct meaning rather than to acquire a set of skills is pursued. Furthermore, a holistic approach is encouraged, wherein both cognitive and affective factors are taken into consideration when discussing reading. Qualitative data-gathering techniques were employed. Interviews were video and audio-taped. Student interview responses, questionnaire answers, observations of and discussions with the student during oral readings and think alouds, as well as student journal entries were used to depict and analyze the student's views. The author's field notes of the interviews, the student's permanent record, the mother's interview responses and the author's reflective journal entries allowed for "thicker" descriptions. The study revealed a discrepancy between the student's views of reading and the actual process of meaning making. She views reading as a performance-based, word-calling exercise, in which meaning making is of secondary importance. The student feels that both her teachers' and her mother's views of reading influenced her own view. The student experiences a constant tension between how she believes she should read and what she feels will actually help her to make meaning. The student is motivated and hard-working, with a strong support network. According to the literature, these qualities, combined with her knowledge of reading strategies, are all that is required to be a good reader. Yet, she continues to experience difficulty. The study concludes that the student's main difficulty with reading is rooted in her views as to its nature and her consequent reluctance to use the strategies she already knows. It recommends that the nature of reading be afforded greater consideration by both educators and researchers.

description: We present a new numerical code developed for the evolution of binary black-hole spacetimes using different initial data and evolution techniques. The code is demonstrated to produce state-of-the-art simulations of orbiting and inspiralling black-hole binaries with convergent waveforms. We also present the first detailed study of the dependence of gravitational waveforms resulting from three-dimensional evolutions of different types of initial data. For this purpose we compare the waveforms generated by head-on collisions of superposed Kerr-Schild, Misner and Brill-Lindquist data over a wide range of initial separations.

description: A Ring Imaging Čerenkov detector built for the BRAHMS experiment at the Brookhaven RHIC is described. This detector has a high index of refraction gas radiator. Čerenkov light is focused on a photo-multiplier based photon detector with a large spherical mirror. The combination of momentum and ring radius measurement provides particle identification from 2.5 GeV/c up to 35 GeV/c for pions and kaons and well above 40 GeV/c for protons during runs that had the radiator index of refraction set at $n-1=1700 \times 10^{-6}$.

description: Quantum entanglement is commonly assumed to be a central resource for quantum computing and quantum simulation. Nonetheless, the capability to detect it in many-body systems is severely limited by the absence of sufficiently scalable and flexible certification tools. This issue is particularly critical in situations where the structure of entanglement is a priori unknown, and where one cannot rely on existing entanglement witnesses. Here, we implement a scheme in which the knowledge of the mean value of arbitrary observables can be used to probe multipartite entanglement in a scalable, certified and systematic manner. Specifically, we rely on positive semidefinite conditions, independent of partial-transposition-based criteria, necessarily obeyed if the data can be reproduced by a separable state. The violation of any of these conditions yields a specific entanglement witness, tailored to the data of interest, revealing the salient features of the data which are impossible to reproduce without entanglement. We validate this approach by probing theoretical many-body states of several hundreds of qubits relevant to existing experiments: a single-particle quench in a one-dimensional $XX$ chain; a many-body quench in a two-dimensional $XX$ model with $1/r^3$ interactions; and thermal equilibrium states of Heisenberg and transverse-field Ising chains. In all cases, these investigations have lead us to discover new entanglement witnesses, some of which could be characterized analytically, generalizing existing results in the literature. In summary, our paper introduces a flexible data-driven entanglement detection technique for uncharacterized quantum many-body states, of immediate relevance to experiments in a quantum advantage regime.

description: Thin foils of the double solid solution $(Zr{_0.5},Ti{_0.5})_{2}(Al_{0.5},Sn_{0.5})C$ MAX phase were in situ irradiated in a transmission electron microscope (TEM) up to a fluence of $1.3\times10^{17} ions$ $cm^{-2}$ (${\sim}$ 7.5 dpa), using 6 keV $He^{+}$ ions. Irradiations were performed in the 350-800 °C temperature range. In situ and post-irradiation examination (PIE) by TEM was used to study the evolution of irradiation-induced defects as function of dose and temperature. Spherical He bubbles and string-like arrangements thereof, He platelets, and dislocation loops were observed. Dislocation loop segments were found to lie in non-basal-planes. At irradiation temperatures ${\geq}$ 450 °C, grain boundary tearing was observed locally due to He bubble segregation. However, the tears did not result in transgranular crack propagation. The intensity of specific spots in the selected area electron diffraction patterns weakened upon irradiation at 450 and 500 °C, indicating an increased crystal symmetry. Above 700 °C this was not observed, indicating damage recovery at the high end of the investigated temperature range. High-resolution scanning TEM imaging performed during the PIE of foils previously irradiated at 700 °C showed that the chemical ordering and nanolamination of the MAX phase were preserved after 7.5 dpa $He^{+}$ irradiation. The size distributions of the He platelets and spherical bubbles were evaluated as function of temperature and dose.
