description: This paper begins the study of infinite-dimensional modules defined on bicomplex numbers. It generalizes a number of results obtained with finite-dimensional bicomplex modules. The central concept introduced is the one of a bicomplex Hilbert space. Properties of such spaces are obtained through properties of several of their subsets which have the structure of genuine Hilbert spaces. In particular, we derive the Riesz representation theorem for bicomplex continuous linear functionals and a general version of the bicomplex Schwarz inequality. Applications to concepts relevant to quantum mechanics, specifically the bicomplex analogue of the quantum harmonic oscillator, are pointed out.

description: As climate change events take place often on a very local scale, the core of the SOCLIMPACT project is a strong focus on downscaling socio-economic consequences. In this report, these outlooks comprise the reference case to which the climate cases are compared. The focus is on Blue Economy sectors, notably tourism, energy, and aquaculture, and maritime transport, as those are key to the economic development of the islands and a core element of European green growth strategies. The modelling framework employed involves an extension of two widely utilised macroeconomic models: an island-level application of the large hybrid general equilibrium model (GEM-E3) and an applied macro-econometric model (GINFORS). Both models feature global coverage and have been originally developed to map mutual macroeconomic interdependences between national economies, and have been further developed in this project. The theoretical and structural differences of the two models (GEM-E3-ISL & GINFORS) enhance the robustness of results. The report is organized as follows. Chapter 2 outlines the methodology and traces the inputs to the two economic models. The implementation strategies of either model are described by economic sector analyzed (tourism, aquaculture, energy and maritime trasnport), but the implementation is the same for each island. Chapter 3 contains the results. They are reported by island, so that interested parties can immediately access the results for “their” respective island. Chapter 4 summarizes findings and concludes with an outlook on future research questions.

description: “Waiting to see me?” asked Dr. Beebe. Was it an implicature or a speech act? Was the utterance intended as an invitation—Come in—or as a request for information—Are you here to see me? I stood up and followed Dr. Beebe into her office. This very first encounter ushered pragmatics into my life. It was also my first step in discovering many different aspects of interaction, and later on, it allowed me to go in my research where others feared to tread, so to speak. Doctor Beebe’s passion for pragmatics, and her ability to ignite her students’ desire to pursue questions relevant to their lives, has kept many of us in her camp. The findings that will be presented in this paper come from my first research study inspired by Dr. Beebe’s class on pragmatics.

description: It is a great pleasure to offer this tribute to Professor Leslie M. Beebe and to help celebrate her vital contribution to the field of cross-cultural pragmatics (CCP). There is no denying that Professor Beebe stands as a distinguished scholar in the field. Anyone who wishes to conduct research on second language (L2) pragmatics would not be able to begin without learning of or citing her work. Among her contributions to the field, I would first like to ponder her groundbreaking call for serious attention to L2 pragmatics as early as the mid-1980s, a time when pragmatics was a neglected area in second language acquisition (SLA) research and L2 pedagogy. In a number of scholarly papers and at conferences, she suggested that “the social rules of speaking” are “basics, not frosting on the cake” (Beebe, 1995, p. 4). Professor Beebe is acknowledged among SLA researchers as one of the earliest linguists who was deeply concerned with cross-cultural misunderstandings (which often lead to unfortunate and offensive cultural stereotyping) resulting from a lack of pragmatic competence.

Also of great importance to the field was Professor Beebe’s contribution to establishing a solid link between pragmatics and SLA by introducing the concept of pragmatic transfer. In the late 1980s, by showing that L2 learners often refer back to rules of speaking from their first language (L1), she successfully demonstrated cross-linguistic influence at the level of pragmatics (Beebe & Takahashi, 1989a; Beebe & Takahashi, 1989b; Beebe, Takahashi, & Ulis-Weltz, 1990). Motivated by her seminal work, the research focus of L2 pragmatics began shifting from CCP to interlanguage pragmatics(ILP), moving beyond the comparison of L1 and L2 pragmatic conventions towards the understanding of the developmental stages that L2 learners go through. Since that time, pragmatics has rapidly grown into a legitimate area of research in the study of SLA. It is now widely accepted that pragmatics is indispensable in helping researchers to understand how L2 learners acquire and use the target language in a meaningful and appropriate manner.
Two-Loop Electroweak Corrections for the K -> pi nu anti-nu Decays

description: The rare K -> pi nu anti-nu decays play a central role in testing the Standard Model and its extensions. Upcoming experiments plan to measure the decay rates with high accuracy. Yet, unknown higher-order electroweak corrections result in a sizeable theory error. We remove this uncertainty by computing the full two-loop electroweak corrections to the top-quark contribution X_t to the rare decays K_L -> pi0 nu anti-nu, K+ -> pi+ nu anti-nu, and B -> X_{d,s} nu anti-nu in the Standard Model. The remaining theoretical uncertainty related to electroweak effects is now far below 1%. Finally we update the branching ratios to find Br(K_L -> pi0 nu anti-nu) = 2.43(39)(6) * 10^-11 and Br(K+ -> pi+ nu anti-nu) = 7.81(75)(29) * 10^-11. The first error summarises the parametric, the second the remaining theoretical uncertainties.

description: We study the Uhlmann holonomy [Rep. Math. Phys. 24, 229 (1986)] of quantum states for hydrogen-like atoms where the intrinsic spin and orbital angular momentum are coupled by the spin-orbit interaction and subject to a slowly varying magnetic field. We show that the holonomy for the orbital angular momentum and spin subsystems is non-Abelian, while the holonomy of the whole system is Abelian. Quantum entanglement in the states of the whole system is crucially related to the non-Abelian gauge structure of the subsystems. We analyze the phase of the Wilson loop variable associated with the Uhlmann holonomy, and find a relation between the phase of the whole system with corresponding marginal phases. Based on the result for the model system we provide evidence that the phase of the Wilson loop variable and the mixed-state geometric phase [E. Sjöqvist {\it et al.} Phys. Rev. Lett. 85, 2845 (2000)] are in general inequivalent.

description: As Leslie’s advisee for seven years in the 1990s, I had the privilege of studying with a master teacher, caring mentor, and brilliant researcher who, over time, also became a cherished friend.  Leslie’s compassion, sense of humor, passion for her subject matter as well as for life, and her academic vitality—or charisma—have impressed me more than she will ever know. I am indeed grateful for the foundation she gave me in sociolinguistics and second language (L2) pragmatics. I have never known a professor who could engage her students in such a powerful, enlightening, and entertaining way, as I experienced in the many captivating three-hour doctoral seminars I took with Leslie over the years.

My doctoral research was on the pragmatic socialization of Chinese immigrant women in a U.S. Chinatown clerical training program, and especially their socialization into appropriate and effective requesting behaviors in English in order to access social services as well as education and job opportunities in high-stakes situations. My research was crucially influenced by Leslie Beebe’s seminal research on interlanguage pragmatics and sociolinguistic aspects of second language learning. Her seminars, articles, and feedback informed and transformed my research. She supported me wholeheartedly in my use of a language socialization framework and qualitative methods (a combination of ethnography, multiple case-study, and narrative), which at the time were quite new in second language pragmatics research.

description: We study the distribution of hard-, soft-, and adaptive soft-thresholding estimators within a linear regression model where the number of parameters k can depend on sample size n and may diverge with n. In addition to the case of known error-variance, we define and study versions of the estimators when the error-variance is unknown. We derive the finite-sample distribution of each estimator and study its behavior in the large-sample limit, also investigating the effects of having to estimate the variance when the degrees of freedom n-k does not tend to infinity or tends to infinity very slowly. Our analysis encompasses both the case where the estimators are tuned to perform consistent model selection and the case where the estimators are tuned to perform conservative model selection. Furthermore, we discuss consistency, uniform consistency and derive the uniform convergence rate under either type of tuning.

description: Computing on graphics processors is maybe one of the most important developments in computational science to happen in decades. Not since the arrival of the Beowulf cluster, which combined open source software with commodity hardware to truly democratize high-performance computing, has the community been so electrified. Like then, the opportunity comes with challenges. The formulation of scientific algorithms to take advantage of the performance offered by the new architecture requires rethinking core methods. Here, we have tackled fast summation algorithms (fast multipole method and fast Gauss transform), and applied algorithmic redesign for attaining performance on gpus. The progression of performance improvements attained illustrates the exercise of formulating algorithms for the massively parallel architecture of the gpu. The end result has been gpu kernels that run at over 500 Gigaflops on one nvidia Tesla C1060 card, thereby reaching close to practical peak. We can confidently say that gpu computing is not just a vogue, it is truly an irresistible trend in high-performance computing.

description: Temperature dependent X-ray diffraction and Raman spectroscopic studies were carried out on the flux grown single crystals of gallium ferrite with Ga:Fe ratio of 0.9:1.1. Site occupancy calculations from the Rietveld refinement of the X-ray data led to the estimated magnetic moment of ~0.60 \muB /f.u. which was in good agreement with the experimental data. Combination of these two measurements indicates that there is no structural phase transition in the material between 18 K to 700 K. A detailed line shape analysis of the Raman mode at ~375 cm^-1 revealed a discontinuity in the peak position data indicating the presence of spin-phonon coupling in gallium ferrite. A correlation of the peak frequency with the magnetization data led to two distinct regions across a temperature ~180 K with appreciable change in the spin-phonon coupling strength from ~ 0.9 cm^-1 (T < 180 K) to 0.12 cm-1 (180 K < T < Tc). This abrupt change in the coupling strength at ~180 K strongly suggests an altered spin dynamics across this temperature.

description: We present the first 3+1 dimensional simulations of non-Abelian plasma instabilities in gauge-covariant Boltzmann-Vlasov equations for the QCD gauge group SU(3) as well as for SU(4) and SU(5). The real-time evolution of instabilities for a plasma with stationary momentum-space anisotropy is studied using a hard-loop effective theory that is discretized in the velocities of hard particles. We find that the numerically less expensive calculations using the group SU(2) essentially reproduce the nonperturbative dynamics of non-Abelian plasma instabilities with higher rank gauge groups provided the mass parameters of the corresponding hard-loop effective theories are the same. In particular we find very similar spectra for the turbulent cascade that forms in the strong-field regime, which is associated with an approximately linear growth of energy in collective fields. The magnitude of the linear growth however turns out to increase with the number of colors.

description: We briefly discuss the current status of Mach's principle in general relativity and point out that its last vestige, namely, the gravitomagnetic field associated with rotation, has recently been measured for the earth in the GP-B experiment. Furthermore, in his analysis of the foundations of Newtonian mechanics, Mach provided an operational definition for inertial mass and pointed out that time and space are conceptually distinct from their operational definitions by means of masses. Mach recognized that this circumstance is due to the lack of any a priori connection between the inertial mass of a body and its Newtonian state in space and time. One possible way to improve upon this situation in classical physics is to associate mass with an extra dimension. Indeed, Einstein's theory of gravitation can be locally embedded in a Ricci-flat 5D manifold such that the 4D energy-momentum tensor appears to originate from the existence of the extra dimension. An outline of such a 5D Machian extension of Einstein's general relativity is presented.

description: Motivated by recent interest in applications of the AdS/CFT correspondence to condensed matter applications involving fermions, we present the supersymmetric completion of the recent massive truncations of IIB supergravity on Sasaki-Einstein manifolds. In particular, we reduce the fermionic sector of IIB supergravity to obtain five dimensional N=2 supergravity coupled to one hypermultiplet and one massive vector multiplet. The supersymmetry transformations and equations of motion are presented and analyzed. Finally, a particularly interesting truncation to N=2 supergravity coupled to a single hypermultiplet is presented which is the supersymmetric completion of the recently constructed bosonic theory dual to a 3+1 dimensional system exhibiting a superconducting phase transition.

One day, I overheard classmates gossiping about a professor from New York who was scheduled to teach the following semester. One student who claimed to have friends in the New York program warned that she was “extremely tough,” “super-strict,” and “slaughters you if you are not good enough.” I visualized this fearsome lady as an old scholar with thick glasses and penetrating eyes. Needless to say, we were positively frightened.

description: We investigate correlations between low-frequency vibrational modes and rearrangements in two-dimensional colloidal glasses composed of thermosensitive microgel particles which readily permit variation of sample packing fraction. At each packing fraction, the particle displacement covariance matrix is measured and used to extract the vibrational spectrum of the "shadow" colloidal glass (i.e., the particle network with the same geometry and interactions as the sample colloid but absent damping). Rearrangements are induced by successive, small reductions in packing fraction. The experimental results suggest that low-frequency quasi-localized phonon modes in colloidal glasses, i.e., modes that present low energy barriers for system rearrangements, are spatially correlated with rearrangements in this thermal system.

description: A unitary coupled-channels model is presented for investigating the decays of heavy mesons and excited meson states into three light pseudoscalar mesons. The model accounts for the three-mesons final state interactions in the decay processes, as required by both the three-body and two-body unitarity conditions. In the absence of the Z-diagram mechanisms that are necessary consequences of the three-body unitarity, our decay amplitudes are reduced to a form similar to those used in the so-called isobar-model analysis. We apply our coupled-channels model to the three-pions decays of a1(1260), pi2(1670), pi2(2100), and D0 mesons, and show that the Z-diagram mechanisms can contribute to the calculated Dalitz plot distributions by as much as 30% in magnitudes in the regions where f0(600), rho(770), and f2(1270) dominate the distributions. Also, by fitting to the same Dalitz plot distributions, we demonstrate that the decay amplitudes obtained with the unitary model and the isobar model can be rather different, particularly in the phase that plays a crucial role in extracting the CKM CP-violating phase from the data of B meson decays. Our results indicate that the commonly used isobar model analysis must be extended to account for the final state interactions required by the three-body unitarity to reanalyze the three-mesons decays of heavy mesons, thereby exploring hybrid or exotic mesons, and signatures of physics beyond the standard model.

A rich phase diagram, including ferromagnetic, antiferromagnetic and non-local ordered phases, emerges in the half-filled one-dimensional case, and is preserved even in presence of a trapping potential.

A quantum critical point (QCP) is identified that separates a commensurate spin-density wave (cSDW) state at strong Hund's rule coupling from a hidden half-metal state at weak Hund's rule coupling when inter-orbital hole hopping is suppressed. Low-energy spinwaves that disperse anisotropically from cSDW momenta are predicted at the QCP. Nested Fermi surfaces similar to those observed experimentally in iron-pnictide materials are also predicted in such case.

description: Professor Leslie M. Beebe has always been an unfailing source of encouragement, a wealth of knowledge and insight, and a wonderful critic. She has taught me much about pragmatics and sociolinguistics, the foundations of my current interests in the social construction of meaning in interaction. My passion for discourse analysis developed while taking several of Professor Beebe’s courses, in particular Interactional Sociolinguistics, where I was introduced to the notion of framing. From our classroom discussions and readings, I developed a conceptualization of framing that became the underlying framework for my subsequent research and current dissertation work on family discourse and identity construction. Below is an adaptation of the “framework of framing” from my data collection paper in the Interactional Sociolinguistics class.

description: The recent detection (Jee etal 2009) of the massive cluster XMMU J2235.3-2557 at a redshift z = 1.4, with an estimated mass M = 6.4 +- 1.2 X 10^14 M_sol, has been claimed to be a possible challenge to the standard LCDM cosmological model. More specifically, the probability to detect such a cluster has been estimated to be 0.005 if a LCDM model with gaussian initial conditions is assumed, resulting in a 3 sigma discrepancy from the standard cosmological model. In this paper we propose to use high redshift clusters as the one detected in Jee etal 2009 to compare the cosmological constant scenario with interacting dark energy models. We show that coupled dark energy models, where an interaction is present between dark energy and cold dark matter, can significantly enhance the probability to observe very massive clusters at high redshift.

description: Several lattice collaborations performing simulations with 2+1 light dynamical quarks have experienced difficulties in fitting their data with standard Nf=3 chiral expansions at next-to-leading order, yielding low values of the quark condensate and/or the decay constant in the Nf=3 chiral limit. A reordering of these expansions seems required to analyse these data in a consistent way. We discuss such a reordering, known as Resummed Chiral Perturbation Theory, in the case of pseudoscalar masses and decay constants, pion and kaon electromagnetic form factors and Kl3} form factors. We show that it provides a good fit of the recent results of two lattice collaborations (PACS-CS and RBC/UKQCD). We describe the emerging picture for the pattern of chiral symmetry breaking, marked by a strong dependence of the observables on the strange quark mass and thus a significant difference between chiral symmetry breaking in the Nf=2 and Nf=3 chiral limits. We discuss the consequences for the ratio of decay constants F_K/F_pi and the Kl3 form factor at vanishing momentum transfer.

description: We analyze the homological behavior of the attaching maps in the 2-local Goodwillie tower of the identity evaluated at S^1. We show that they exhibit the same homological behavior as the James-Hopf maps used by N. Kuhn to prove the 2-primary Whitehead conjecture. We use this to prove a calculus form of the Whitehead conjecture: the Whitehead sequence is a contracting homotopy for the Goodwillie tower of S^1 at the prime 2.

Tunable graphene bandgaps from superstrate mediated interactions
Creators: name: Hague, J. P.
Publisher: name: arXiv

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: A theory is presented for the strong enhancement of graphene-on-substrate bandgaps by attractive interactions mediated through phonons in a polarizable superstrate. It is demonstrated that gaps of up to 1eV can be formed for experimentally achievable values of electron-phonon coupling and phonon frequency. Gap enhancements range between 1 and 4, indicating possible benefits to graphene electronics through greater bandgap control for digital applications, lasers, LEDs and photovoltaics through the relatively simple application of polarizable materials such as SiO2 and Si3N4.

description: As a first-semester doctoral student in Leslie Beebe’s Linguistic Anthropology class, when the time came to start developing my final project, I had read seminal articles on language socialization, as well as more recent studies. I also had great data (20 months’ worth of video recordings of interaction between a child and her caregivers), but no direction in which to take it. As Leslie advised, I reviewed the video recordings to find excerpts that seemed superficially interesting to me, and then transcribed those instances in detail to determine why I had found them interesting in the first place. Again and again in office hours, she urged me to find the gap in the literature and to be clear about the story I wanted to tell with my data. Working with Leslie to narrow my focus led me to a work process that I have returned to time and again in subsequent projects. It is a process I am utilizing now as I analyze data for my dissertation. I will briefly present my findings from that earlier language socialization study below, and will conclude by examining how the experience of working on that project has shaped my subsequent work.

description: In this paper our aim is to show some mean value inequalities for the modified Bessel functions of the first and second kinds. Our proofs are based on some bounds for the logarithmic derivatives of these functions, which are in fact equivalent to the corresponding Turán type inequalities for these functions. As an application of the results concerning the modified Bessel function of the second kind we prove that the cumulative distribution function of the gamma-gamma distribution is log-concave. At the end of this paper several open problems are posed, which may be of interest for further research.

description: Let K be a subfield of the real field, D be a discrete subset of K and f : D^n -> K be a function such that f(D^n) is somewhere dense. Then (K,f) defines the set of integers. We present several applications of this result. We show that K expanded by predicates for different cyclic multiplicative subgroups defines the set of integers. Moreover, we prove that every definably complete expansion of a subfield of the real field satisfies an analogue of the Baire Category Theorem.

description: Introduction
Murine studies have shown that apolipoprotein E modulates pulmonary function during development, aging, and allergen-induced airway disease. It is not known whether the polymorphic human APOE gene influences pulmonary function.

Objectives
We assessed whether an association exists between the polymorphic human APOE ε2, ε3, and ε4 alleles and pulmonary function among participants in the Long Life Family Study.

Methods
Data from 4,468 Caucasian subjects who had genotyping performed for the APOE ε2, ε3, and ε4 alleles were analyzed, with and without stratification by sex. Statistical models were fitted considering the effects of the ε2 allele, defined as ε2/2 or ε2/3 genotypes, and the ε4 allele, defined as ε3/4 or ε4/4 genotypes, which were compared to the ε3/3 genotype.

Results
The mean FEV1/FVC ratio (the forced expiratory volume in one second divided by the forced vital capacity) was lower among women with the ε4 allele as compared to women with the ε3/3 genotype or the ε2 allele. Carriage of the APOE ε4 allele was associated with FEV1/FVC, which implied lower values. Further analysis showed that the association primarily reflected women without lung disease who were older than 70 years. The association was not mediated by lipid levels, smoking status, body mass index, or cardiovascular disease.

Conclusions
This study for the first time identifies that the APOE gene is associated with modified lung physiology in women. This suggests that a link may exist between the APOE ε4 allele, female sex, and a reduction in the FEV1/FVC ratio in older individuals.

description: Objective
The aim of this paper is to investigate how doctors working in primary health care in Latin American address patients with common mental disorders and to investigate how stigma can affect their clinical decisions.

Methods
Using a cross-sectional design, we applied an online self-administered questionnaire to a sample of 550 Primary Care Physicians (PCPs) from Bolivia, Brazil, Cuba and Chile. The questionnaire collected information about sociodemographic variables, training and experience with mental health care. Clinicians’ stigmatizing attitudes towards mental health were measured using the Mental Illness Clinicians' Attitudes Scale (MICA v4). The clinical decisions of PCPs were assessed through three clinical vignettes representing typical cases of depression, anxiety and somatization.

Results
A total of 387 professionals completed the questionnaires (70.3% response rate). The 63.7% of the PCPs felt qualified to diagnose and treat people with common mental disorders. More than 90% of the PCPs from Bolivia, Cuba and Chile agreed to treat the patients presented in the three vignettes. We did not find significant differences between the four countries in the scores of the MICA v4 stigma levels, with a mean = 36.3 and SD = 8.3 for all four countries. Gender (p = .672), age (p = .171), training (p = .673) and years of experience (p = .28) were unrelated to stigma. In the two multivariate regression models, PCPs with high levels of stigma were more likely to refer them to a psychiatrist the patients with depression (OR = 1.03, 95% CI, 0.99 to 1.07 p<0.05) and somatoform symptoms somatoform (OR = 1.03, 95% CI, 1.00 to 1.07, p<0.05) to a psychiatrist.

Discussion
The majority of PCPs in the four countries were inclined to treat patients with depression, anxiety and somatoform symptoms. PCPs with more levels of stigma were more likely to refer the patients with depression and somatoform symptoms to a psychiatrist. Stigmatizing attitudes towards mental disorders by PCPs might be important barriers for people with mental health problems to receive the treatment they need in primary care.
From prison to plate : how connections between men in federal custody and Indigenous families impacts food security, food sovereignty and wellbeing
Creators: name: Timler, Kelsey
Publisher: name: University of British Columbia

description: For many Aboriginal communities in Canada, the legacies of historic and ongoing colonialism and the impacts of marginalization, dispossession and racism have produced barriers to meaningful and nutritious foods and foodways. This has resulted in high rates of diet-related diseases among Aboriginal populations. The same factors that impact Aboriginal food security also create barriers to employment and housing, and inequitable treatment within the criminal justice system. Founded in 2012, a prison garden based at a minimum security correctional institution in Mission, British Columbia (BC), attempts to address these correlates of crime and poor health by engaging men in federal custody in meaningful activity; specifically, the growing and subsequent donation of organic produce. The fruits and vegetables grown in the garden are donated to a variety of local organizations and Aboriginal communities, including the Tŝilhqot’in Nation of central interior BC. This ethnographic research, founded in critical social justice theories and the principles of food sovereignty, set out to understand the impacts of the garden on both the participating men and the recipient Tŝilhqot’in communities. Qualitative interviews were conducted with 10 participating men in custody, 10 Tŝilhqot’in recipients, and 5 program stakeholders. Iterative thematic analysis revealed multi-layered impacts for the participating men, starting with access to food and increasing over time to include gardening as a means to figuratively escape the correctional environment, to work productively, to give back, and as a means to begin imagining meaningful futures outside of prison. The distribution of vegetables within the Tŝilhqot’in highlighted a passive coalescence with histories of culinary imperialism, truncating impacts to two layers: access to food and connections with the men in prison. Drawing on the insights of both the men and Tŝilhqot’in community members and the theoretical principles of food sovereignty, decolonizing methodologies and food as social justice, potential ways to acknowledge the legacies of colonialism, increase connection between the prison and the communities, and increase impacts are discussed.
