description: Experiments in organic semiconductors (polyacenes) evidence a strong super quadratic increase of the current-voltage (I-V) characteristic at voltages in the transition region between linear (Ohmic) and quadratic (trap free space-charge-limited-current) behaviours. Similarly, excess noise measurements at a given frequency and increasing voltages evidence a sharp peak of the relative spectral density of the current noise in concomitance with the strong super-quadratic I-V characteristics. Here we discuss the physical interpretation of these experiments in terms of an essential contribution from field assisted trapping-detrapping processes of injected carriers. To this purpose, the fraction of filled traps determined by the I-V characteristics is used to evaluate the excess noise in the trap filled transition (TFT) regime. We have found an excellent agreement between the predictions of our model and existing experimental results in tetracene and pentacene thin films of different length in the range $0.65 ÷35 \ μm$.

description: As part of the User Interface Software course in the Human-Computer Interaction Institute at Carnegie Mellon University, the students and instructor developed a set of 7 benchmark tasks. These benchmarks are designed to be representative of a wide range of user interface styles, and have been implemented in about 20 different toolkits on different platforms in different programming languages.. The students’ written reports suggest that by implementing the benchmarks, they are learning the strengths and weaknesses of the various systems. Implementations of the benchmarks by a number of more experienced toolkit users and developers suggest that the benchmarks also do a good job of identifying the effectiveness of the toolkits for different kinds of user interfaces, and point out deficiencies in the toolkits. Thus, benchmarks seem to be very useful both for teaching and for evaluating user interface development environments.

description: Within the extended vector meson dominance model, we investigate the $e^+ e^- \to Λ^+_c \barΛ^-_c$ reaction and the electromagnetic form factors of the charmed baryon $Λ_c^+$. The model parameters are determined by fitting them to the cross sections of the process $e^+e^-\rightarrow Λ_c^+ \barΛ_c^-$ and the magnetic form factor $|G_M|$ of $Λ^+_c$. By considering four charmoniumlike states, called $ψ(4500)$, $ψ(4660)$, $ψ(4790)$, and $ψ(4900)$, we can well describe the current data on the $e^+ e^- \to Λ^+_c \barΛ^-_c$ reaction from the reaction threshold up to $4.96 \ \mathrm{GeV}$. In addition to the total cross sections and $|G_M|$, the ratio $|G_E/G_M|$ and effective form factor $|G_{\mathrm{eff}}|$ for $Λ^+_c$ are also calculated, and found that these calculations are consistent with the experimental data. Within the fitted model parameters, we have also estimated the charge radius of the charmed $Λ_c^+$ baryon.

Taking Quantitative Evaluation of Intellectual Labour Seriously: A Debate about Juan Pablo Pardo-Guerra’s The Quantified Scholar (CUP, 2022)
Creators: name: Chesta, Riccardo Emilio
Publisher: name: Sociologica
Year: 2024

description: The rise of quantitative research evaluation has changed not only the way knowledge is rated and ranked, but the way scientific knowledge is produced. This Focus discusses the outcomes of Juan Pablo Pardo-Guerra’s research on the transformation of the British social sciences. While pushing social scientists to adapt to the new canons of evaluation, research assessment frameworks have increased disciplinary homogeneity at the detriment of diversity. Moving beyond the specificity of the British case, the comments that follow critically engage with the perspectives and proposals advanced by the author.

description: We discuss the gravitational wave (GW) spectra predicted from the electroweak scalegenesis of the Higgs portal type with a large number of dark chiral flavors, which many flavor QCD would underlie and give the dynamical explanation of the negative Higgs portal coupling required to trigger the electroweak symmetry breaking. We employ the linear-sigma model as the low-energy description of dark many flavor QCD and show that the model undergoes ultra-supercooling due to the produced strong first-order thermal phase transition along the (approximately realized) flat direction based on the Gildener-Weinberg mechanism. Passing through evaluation of the bubble nucleation/percolation, we address the reheating and relaxation processes, which are generically non-thermal and nonadiabatic. Parametrizing the reheating epoch in terms of the e-folding number, we propose proper formulae for the redshift effects on the GW frequencies and signal spectra. It then turns out that the ultra-supercooling predicted from the Higgs-portal scalegenesis generically yields none of GW signals with the frequencies as low as nano Hz, unless the released latent heat is transported into another sector other than reheating the universe. Instead, models of this class prefer to give the higher frequency signals and still keeps the future prospected detection sensitivity, like at LISA, BBO, and DECIGO, etc. We also find that with large flavors in the dark sector, the GW signals are made further smaller and the peak frequencies higher. Characteristic phenomenological consequences related to the multiple chiral scalars include the prediction of dark pions with the mass much less than TeV scale, which is also briefly addressed.

description: We derive the analog of the Cachazo-Svrcek-Witten (CSW) diagrammatic Feynman rules for four dimensional Yang-Mills gauge theory coupled to a massive colored scalar. The mass term is shown to give rise to a new tower of vertices in addition to the CSW vertices for massless scalars in non-supersymmetric theories. The rules are derived directly from an action, once through a canonical transformation within light-cone Yang-Mills and once by the construction of a twistor action. The rules are tested against known results in several examples and are used to simplify the proof of on-shell recursion relations for amplitudes with massive scalars.

Service-Learning: Boldly Going Where EAL Students Have Not Gone Before

Publisher: name: BC TEAL Journal
Year: 2017

description: Service-learning is an experiential pedagogy which integrates curriculum and volunteer service through ongoing reflection. Research suggests that service-learning offers notable benefits for post-secondary English-as-an-additional-language (EAL) students. However, most of the researchers have studied EAL students within the United States; far fewer have examined EAL students in the Canadian context. This paper reports on a study of the impact of service-learning on EAL students at a Canadian university in British Columbia. A first-year service-learning elective has been offered at the university since Fall 2009. This course is taught by faculty from the ESL Department who have a Master’s degree or equivalent in a related field. This study investigated the impact of the elective on EAL students’ English proficiency. Data were collected from students through surveys, interviews, and journals. Additionally, the grade point averages (GPA’s) of EAL students in first-year university English composition were examined, comparing those EAL students who took the service-learning elective (Group A) with those who did not (Group B). Grade analysis showed whereas Group B had a GPA of 2.15 on a 4.33 scale for first-year English composition, the subset of Group A who took first-year English composition in the semester immediately following service-learning achieved a GPA of 2.55. The results supported service-learning as an effective pedagogy for EAL students.

description: System-wide graceful degradation may be a viable approach to improving dependability in computer systems. In order to evaluate and improve system-wide graceful degradation we present initial work on a component-based model that will explicitly define graceful degradation as a system property, and measure how well a system gracefully degrades in the presence of multiple combinations of component failures. The system’s software architecture plays a major role in this model, because the interface and component specifications embody the architecture’s abstraction principle. We use the architecture to group components into subsystems that enable reasoning about overall system utility. We apply this model to an example distributed embedded control system and report on initial results.

description: SPACE (SPectroscopic All-sky Cosmic Explorer) is a class-M mission proposed to ESA for the Cosmic Vision 2015-2025 call and recently promoted to the next assessment study phase. SPACE will produce the first all-sky spectroscopic survey of the Universe, taking spectra of more than 500 million galaxies over a wide range of redshifts. SPACE will operate in slit mode (MEMS) at R~400 between 0.8 and 1.8micron down to AB~23, providing redshifts to an accuracy of Delta z~0.001, regardless on the presence of bright emission lines, together with the most relevant physical and evolutionary properties. The catalog of spectroscopic redshift will allow to place the ultimate constraints on the Baryon Acoustic Oscillations and the nature of Dark Energy. By obtaining the first 3-D all-sky map of the Universe at z~2 and beyond, SPACE will trace the growth rate of cosmic structures, the large scale structure of luminous baryons and its cosmic evolution. Besides the all-sky survey, SPACE will carry out a deep extragalactic survey over an area of ~10 sq. deg., enabling a most powerful supernova search program, and a galactic plane survey in integral field mode. Approximately 30% of the time will be open. Due to its versatility, SPACE is a ``self-sufficient'' observatory which can attack and solve the most compelling questions on the nature of the Dark Energy without complementary data from the Earth or space. Its unique wide-field capabilities in the near-IR make SPACE the ideal complement to JWST, ALMA, and the future 25-50 m telescopes.

Supporting Adult Learners with Refugee Experiences through English Language Instruction
Creators: name: Khatri, Raj
Publisher: name: BC TEAL Journal

description: Canada welcomes around 24,000 refugees annually (Citizenship and Immigration Canada 2015; 2016). Many adult learners with refugee experiences join English as an Additional Language (EAL) classes every year, whether these classes be federally or provincially funded. These adult learners with refugee experiences bring to EAL classes varied educational and life experiences. Some of these learners have little or interrupted schooling (Finn, 2010). Learners with this profile may have also encountered forced displacement, loss of identity, torture, and trauma. These experiences, along with post-traumatic stress disorder (PTSD), which some people with this background may suffer from, can lead to concentration difficulties and memory loss (Hauksson, 2003). This, in turn, can negatively impact additional language acquisition (Finn, 2010). When EAL instructors are unaware of refugee experiences, they may find it difficult to deal with these circumstances appropriately, which may create uncomfortable situations both for learners with refugee experiences and their instructors in class. To work with such learners, it is important that EAL instructors be very skilled, experienced, and patient. The present article provides readers with an opportunity to understand various refugee experiences, the acculturation process these learners may go through, and lesson planning strategies that can be incorporated when supporting adult learners with refugee experiences.

Academic Language in K-12: What Is It, How Is It Learned, and How Can We Measure It?

Year: 2016

description: Using Beck, McKeown and Kucan’s (2002) three-tiered model as a general framework for vocabulary, this article sheds light on the construct of academic vocabulary and how it might be measured. Using illustrative writing samples of student work of different genres and drawing on corpus based studies, I highlight the distinction between general, high utility academic vocabulary visible in expository mode (Tier 2), and narrative vocabulary (Tier 1) on the one hand; and general, high utility academic vocabulary and literary vocabulary associated with English Language Arts literature-based curriculum (Tier 3). Tier 2 words have consistently correlated with academic achievement across disciplinary boundaries, especially at post-secondary levels. Suggestions are made for policy reform, curriculum, and assessment approaches that will afford more equitable access to post-secondary programs of study for the growing numbers of English language learners across Canada, including in provinces such as Alberta and British Columbia.

description: Agama (Action-based Galaxy Modelling Architecture) is a software library intended for a broad range of tasks within the field of stellar dynamics. As the name suggests, it is centered around the use of action/angle formalism to describe the structure of stellar systems, but this is only one of its many facets. The library contains a powerful framework for dealing with arbitrary density/potential profiles and distribution functions (analytic, extracted from N-body models, or fitted to the data), a vast collection of general-purpose mathematical routines, and covers many aspects of galaxy dynamics up to the very high-level interface for constructing self-consistent galaxy models. This document serves two purposes. First of all, this is a detailed reference for the library itself. Second, it describes various mathematical and numerical methods that could be applicable in a broader context. These include: (1) one- and multidimensional interpolation using cubic and quintic splines; (2) penalized spline fitting of noisy data and penalized spline density estimation; (3) adaptive rejection sampling from multidimensional probability distributions; (4) computation of gravitational potentials using spherical- and azimuthal-harmonic expansions; (5) Staeckel fudge method for computing action/angle variables; (6) a general discussion about good programming practices.

description: Using infrared photometry from the Spitzer Space Telescope, we perform the first inventory of aromatic feature emission (also commonly referred to as polycyclic aromatic hydrocarbon emission) for a statistically complete sample of star-forming galaxies in the local volume. The photometric methodology involved is calibrated and demonstrated to recover the aromatic fraction of the Infrared Array Camera 8 μm flux with a standard deviation of 6% for a training set of 40 SINGS galaxies (ranging from stellar to dust dominated) with both suitable mid-infrared Spitzer Infrared Spectrograph spectra and equivalent photometry. A potential factor of 2 improvement could be realized with suitable 5.5 μm and 10 μm photometry, such as what may be provided in the future by the James Webb Space Telescope. The resulting technique is then applied to mid-infrared photometry for the 258 galaxies from the Local Volume Legacy (LVL) survey, a large sample dominated in number by low-luminosity dwarf galaxies for which obtaining comparable mid-infrared spectroscopy is not feasible. We find the total LVL luminosity due to five strong aromatic features in the 8 μm complex to be 2.47 × 1010 L with a mean volume density of 8.8 × 106 L Mpc–3. Twenty-four of the LVL galaxies, corresponding to a luminosity cut at MB = –18.22, account for 90% of the aromatic luminosity. Using oxygen abundances compiled from the literature for 129 of the 258 LVL galaxies, we find a correlation between metallicity and the aromatic-to-total infrared emission ratio but not the aromatic-to-total 8 μm dust emission ratio. A possible explanation is that metallicity plays a role in the abundance of aromatic molecules relative to the total dust content, but other factors, such as star formation and/or the local radiation field, affect the excitation of those molecules.
Color superconductivity and charge neutrality in Yukawa theory

description: It is generally believed that when Cooper pairing occurs between two different species of fermions, their Fermi surfaces become locked together so that the resultant state remains 'neutral', with equal number densities of the two species, even when subjected to a chemical potential that couples to the difference in number densities. This belief is based on mean-field calculations in models with a zero-range interaction, where the anomalous self-energy is independent of energy and momentum. Following up on an early report of a deviation from neutrality in a Dyson-Schwinger calculation of color-flavor-locked quark matter, we investigate the neutrality of a two-species condensate using a Yukawa model which has a finite-range interaction. In a mean field calculation we obtain the full energy-momentum dependence of the self energy and find that the energy dependence leads to a population imbalance in the Cooper-paired phase when it is stressed by a species-dependent chemical potential. This gives some support to the suggestion that the color-flavor-locked phase of quark matter might not be an insulator.

Growth: The Relationship Between Metanoia and Additional Language Learning in EAP
Creators: name: Ranson, Samantha
Publisher: name: BC TEAL Journal
Year: 2016

description: Taken from ancient Greek philosophy, metanoia refers to a fundamental shift in habits of the mind. Until now, the connection between metanoia and additional language learning has not been fully examined, particularly in higher education contexts. This study explored the progression of metanoia in the additional language learning of students enrolled in an English for academic purposes (EAP) program. The research question for this study related to how EAP students experienced metanoia, and what the relationship was with their additional language learning. Employing a socio-cognitive theoretical framework, qualitative research methods were used to combine an online questionnaire (n = 9) and follow-up interviews (n = 5) to collect data. Meaningful responses in the data were coded, and the codes were gathered together into emergent themes. A major theme emerging from the data in connection to metanoia and additional language learning was that of growth, particularly in terms of confidence, language learning, younger life, academic skills, organization, tolerance, community, and awareness. This study provides insight into the lives of English language learners in academic settings, and offers suggestions related to fostering an EAP environment that supports English language learning.

description: The dynamics of a weakly interacting Bose gas at low temperatures is close to integrable due to the approximate quadratic nature of the many-body Hamiltonian. While the short-time physics after an abrupt ramp of the interaction constant is dominated by the integrable dynamics, integrability is broken at longer times by higher-order interaction terms in the Bogoliubov Hamiltonian, in particular by Beliaev-Landau scatterings involving three quasiparticles. The two-stage relaxation process is highlighted in the evolution of local observables such as the density-density correlation function: a dephasing mechanism leads the system to a prethermal stage, followed by true thermalization conveyed by quasiparticle collisions. Our results bring the crossover from prethermalization to thermalization within reach of current experiments with ultracold atomic gases.

description: We discuss the geometry of transverse linear sections of the spinor tenfold $X$, the connected component of the orthogonal Grassmannian of 5-dimensional isotropic subspaces in a 10-dimensional vector space equipped with a non-degenerate quadratic form. In particular, we show that as soon as the dimension of a linear section of $X$ is at least 5, its integral Chow motive is of Lefschetz type. We discuss classification of smooth linear sections of $X$ of small codimension; in particular we check that there is a unique isomorphism class of smooth hyperplane sections and exactly two isomorphism classes of smooth linear sections of codimension 2. Using this, we define a natural quadratic line complex associated with a linear section of $X$. We also discuss the Hilbert schemes of linear spaces and quadrics on $X$ and its linear sections.

description: With smart-phones becoming increasingly commonplace, there has been a subsequent surge in applications that continuously track the location of users. However, serious privacy concerns arise as people start to widely adopt these applications. Users will need to maintain policies to determine under which circumstances to share their location. Specifying these policies however, is a cumbersome task, suggesting that machine learning might be helpful. In this paper, we present a user-controllable method for learning location sharing policies. We use a classifier based on multivariate Gaussian mixtures that is suitably modified so as to restrict the evolution of the underlying policy to favor incremental and therefore human-understandable changes as new data arrives. We evaluate the model on real location-sharing policies collected from a live location-sharing social network, and we show that our method can learn policies in a user-controllable setting that are just as accurate as policies that do not evolve incrementally. Additionally, we highlight the strength of the generative modeling approach we take, by showing how our model easily extends to the semi-supervised setting.

That this might also apply to infinite-dimensional systems is the inspiration for this work. As an example the 2D Euler equation is studied. Among other results this study suggests that the coherent structures observed in 2D hydrodynamics are associated to configurations that maximize stochastically stable measures uniquely determined by the boundary conditions in mode space.

description: This letter presents an experimental characterization technique for assessing the performance of terahertz harmonic mixers across a wide frequency range. The total signal transfer loss of three mixers was measured in both up- and down-conversion configurations, and the conversion loss was determined through the solution of a linear system of equations. The proposed method uses LO signals with a frequency offset to ensure single sideband measurements, thereby eliminating the need for image-reject filters. The three-mixer method was verified by measurements of millimeter-wave mixers, which matched the traditional characterization method using a calibrated source and power meter. Given this successful millimeter-wave demonstration, we characterized three WM-86 Schottky diode x4-harmonic mixers from 2.2 to 3 THz. This technique presents a notable advantage for conducting broadband mixer characterizations, particularly in the terahertz frequency regime which lacks tunable, wide-band sources.

description: In the spring of 2015, the Centre for Academic Communication (CAC) at the University of Victoria began a series of projects aimed at understanding the needs of undergraduate and graduate students with English as additional language (EAL), with the goal of increasing the effectiveness of the Centre’s programming. The first project, detailed in this article, concentrated on identifying student perceptions and use of the Centre’s programming and aimed to elicit suggestions as to how the CAC could better meet student needs. To do this, we facilitated two focus group interviews consisting of EAL graduate (N=6) and undergraduate (N=4) students. Participants responded that the timing of programming should better reflect their schedules, and that programming should be more discipline specific and better designed for graduate students. They also felt that they did not receive enough critical feedback and that there was a lack standardization across tutorials and workshops. However, the participants also felt that the tutors were helpful, the programming provided a good addition to their studies, and the supports increased their confidence. Two unexpected findings were that, generally, students accessed one kind of programming offered by the Centre, rather than taking advantage of the range of offerings, and that students had misconceptions about the Centre’s offerings and how to use them. It is hoped that this study will help inform other student academic support services about focus group research for the purposes of program evaluation and collecting student feedback.

description: Over the last fifty years since the discovery of pulsars, our understanding of where and how pulsars emit the radiation we observe has undergone significant revision. The location and mechanisms of high-energy radiation are intimately tied to the sites of particle acceleration. The evolution of emission models has paralleled the development of increasingly more sensitive telescopes, especially at high energies. I will review the history of pulsar emission modeling, from the early days of gaps at the polar caps, to outer gaps and slot gaps in the outer magnetosphere, to the present era of global magnetosphere simulations that locate most acceleration and high- energy emission in the current sheets.

Spontaneous Supersymmetry Breaking by Large-N Matrices

description: Motivated by supersymmetry breaking in matrix model formulations of superstrings, we present some concrete models, in which the supersymmetry is preserved for any finite $N$, but gets broken at infinite $N$, where $N$ is the rank of matrix variables. The models are defined as supersymmetric field theories coupled to some matrix models, and in the induced action obtained after integrating out the matrices, supersymmetry is spontaneously broken only when $N$ is infinity. In our models, the large value of $N$ gives a natural explanation for the origin of small parameters appearing in the field theories which trigger the supersymmetry breaking. In particular, in the case of the O'Raifeartaigh model coupled to a certain supersymmetric matrix model, a nonsupersymmetric metastable vacuum appears near the origin of the field space, which is far from the position of the supersymmetric vacuum. We estimate its lifetime as a function of $N$.

description: This exploratory mixed-methods study examined the influence of an on-campus canine therapy program on linguistically diverse international students’ perceptions of their English language development and stress. Participants were recruited from English language support classes at a mid-size western Canadian university and were randomly selected from a larger pool of participants indicating interest in the study. Seven participants attended five canine therapy sessions in which they interacted with certified therapy dogs working as part of a campus initiative to reduce stress and homesickness on campus. Both formative and summative data collection was done with students completing weekly stress assessments, responding to summative questions asked in an interview, and elaborating on their views in a focus group discussion. The following key themes emerged with students describing: 1) decreased overall stress; 2) improvements in their sense of belonging in the campus community with dogs as social catalysts; and 3) increased opportunities to practice oral language skills through interactions with dog handlers and fellow students in the lab. Implications are discussed within the context of reducing the affective filter for language learners and increasing accessibility to programs for international students.

description: Vulnerability detectors based on deep learning (DL) models have proven their effectiveness in recent years. However, the shroud of opacity surrounding the decision-making process of these detectors makes it difficult for security analysts to comprehend. To address this, various explanation approaches have been proposed to explain the predictions by highlighting important features, which have been demonstrated effective in other domains such as computer vision and natural language processing. Unfortunately, an in-depth evaluation of vulnerability-critical features, such as fine-grained vulnerability-related code lines, learned and understood by these explanation approaches remains lacking. In this study, we first evaluate the performance of ten explanation approaches for vulnerability detectors based on graph and sequence representations, measured by two quantitative metrics including fidelity and vulnerability line coverage rate. Our results show that fidelity alone is not sufficient for evaluating these approaches, as fidelity incurs significant fluctuations across different datasets and detectors. We subsequently check the precision of the vulnerability-related code lines reported by the explanation approaches, and find poor accuracy in this task among all of them. This can be attributed to the inefficiency of explainers in selecting important features and the presence of irrelevant artifacts learned by DL-based detectors.

description: The demand for new thermal neutron detectors as an alternative to 3He tubes in research, industrial, safety and homeland security applications, is growing. These needs have triggered research and development activities about new generations of thermal neutron detectors, characterized by reasonable efficiency and gamma rejection comparable to 3He tubes. In this paper we show the state of the art of a promising low-cost technique, based on commercial solid state silicon detectors coupled with thin neutron converter layers of 6LiF deposited onto carbon fiber substrates. A few configurations were studied with the GEANT4 simulation code, and then calibrated at the PTB Thermal Neutron Calibration Facility. The results show that the measured detection efficiency is well reproduced by the simulations, therefore validating the simulation tool in view of new designs. These neutron detectors have also been tested at neutron beam facilities like ISIS (Rutherford Appleton Laboratory, UK) and n_TOF (CERN) where a few samples are already in operation for beam flux and 2D profile measurements. Forthcoming applications are foreseen for the online monitoring of spent nuclear fuel casks in interim storage sites.
The Dynamic Rhetorical Structures of TESOL Conference Abstracts

description: In English Language Teaching (ELT), conferences have developed into valuable venues for both researchers and practitioners to learn and share their knowledge bases. Attending and presenting at academic conferences has become an important form of scholarship and professional development for researchers, in-service teachers, and pre-service teachers. In the field of ELT, the TESOL International Convention and Language Expo is a highly prestigious event but, for those wanting to present, highly competitive. The conference abstract is the basis of being granted permission to present at such conferences and, as such, is a critical gate-keeping genre. The goal of the present empirical study is to examine rhetorical features of successful conference abstracts (N=16) with the hope that the results will help teachers write their own conference proposals. Using genre analysis (Swales, 1990), the rhetorical structures of conference abstracts for TESOL 2014 were collected and annotated for rhetorical moves and steps following Halleck and Connor (2006). This detailed analysis uncovered rhetorical patterns common to all conference abstracts. Despite this, variations within proposals were identified in terms of number of moves and specific sequencing. Guidance and tips for novice writers are presented, and connections are made to local TESOL affiliates, such as BC TEAL.
