description: Game AI competitions are important to foster research and development on Game AI and AI in general. These competitions supply different challenging problems that can be translated into other contexts, virtual or real. They provide frameworks and tools to facilitate the research on their core topics and provide means for comparing and sharing results. A competition is also a way to motivate new researchers to study these challenges. In this document, we present the Geometry Friends Game AI Competition. Geometry Friends is a two-player cooperative physics-based puzzle platformer computer game. The concept of the game is simple, though its solving has proven to be difficult. While the main and apparent focus of the game is cooperation, it also relies on other AI-related problems such as planning, plan execution, and motion control, all connected to situational awareness. All of these must be solved in real-time. In this paper, we discuss the competition and the challenges it brings, and present an overview of the current solutions.

description: We show that Neural ODEs, an emerging class of time-continuous neural networks, can be verified by solving a set of global-optimization problems. For this purpose, we introduce Stochastic Lagrangian Reachability (SLR), an abstraction-based technique for constructing a tight Reachtube (an over-approximation of the set of reachable states over a given time-horizon), and provide stochastic guarantees in the form of confidence intervals for the Reachtube bounds. SLR inherently avoids the infamous wrapping effect (accumulation of over-approximation errors) by performing local optimization steps to expand safe regions instead of repeatedly forward-propagating them as is done by deterministic reachability methods. To enable fast local optimizations, we introduce a novel forward-mode adjoint sensitivity method to compute gradients without the need for backpropagation. Finally, we establish asymptotic and non-asymptotic convergence rates for SLR.

description: Language immersion programs are becoming more available as a form of school choice in both private and public education in the United States and beyond. While there is research on the benefits of immersion education regarding overall intelligence, there is still much skepticism as to why parents would place their child in an immersion program vs. a traditional program where all academics are taught in English. This study presents the data from two schools in the same school district in a Midwest state that took the bold move to create a stand-alone one-way Spanish full immersion school. The analysis show that students educated in the immersion program scored statistically better than their similarly situated peers on the Smarter Balanced Assessment in mathematics and the Measure of Academic Progress in mathematics and reading. The analysis also showed the students educated in the immersion program performed better than their similarly situated peers on the Smarter Balanced Assessment in English language arts and the ABC District Writing Assessment, but statistical significance was not found. While this study is based upon a one-way full immersion program, the findings may also apply to dual and two-way immersion programs where similar results may be achieved for English Language Learners educated in their native language as well as in English.

description: We show that adsorbates on surfaces can form islands even if there are no attractive interactions. Instead strong repulsion between adsorbates at short distances can lead to islands, because such islands increase the entropy of the adsorbates that are not part of the islands. We suggest that this mechanism cause the observed island formation in O/Pt(111), but it may be important for many other systems as well.

description: Dual or two-way immersion programs utilize two languages of instruction to promote bilingualism and biliteracy. This study examined the impact of dual language instruction on the reading achievement and language acquisition of English language learners (ELL) at the elementary level in a public school district in a Midwestern state. The school population included 778 students in which 400 students were enrolled in the dual language program (327 ELL, 73 English) and 378 students were enrolled in a traditional setting (225 ELL, 153 English). A one-way analysis of variance (ANOVA) was used to compare the means of reading scores of dual language and of English-only students with no statistically significant effect found. A factorial two-way ANOVA was conducted to compare the means of reading subtest percentile scores, and statistically significant differences were found at the .05 level for the Prereading/Early Reading and Instruction subtests. The results of this study support the implementation of two-way, or dual language models of instruction for school-aged native-English and emergent bilinguals.

Their main objective is to detect and characterize other Earth-like planets, analyze the composition of their atmospheres and their capability to sustain life, as we know it. Darwin and TPF-I are currently in study phase. A number of mission architectures of 3 and 4 free flying telescopes are evaluated on the basis of the interferometer's response, ability to distinguish multiple planet signatures and starlight rejection capabilities. The characteristics of the new configurations are compared also to the former, more complex Bowtie baseline architectures as well as evaluated on base of their science capability.

description: A plethora of applications have recently motivated extensive efforts on the generation of low noise Kerr solitons and coherent frequency combs in various platforms ranging from fiber to whispering gallery and integrated microscale resonators. However, the Kerr (cubic) nonlinearity is inherently weak, and in contrast, strong quadratic nonlinearity in optical resonators is expected to provide an alternative means for soliton formation with promising potential. Here, we demonstrate the formation of a dissipative quadratic soliton via non-stationary optical parametric amplification in the presence of significant temporal walk-off between pump and signal leading to half-harmonic generation accompanied by a substantial pulse compression (exceeding a factor of 40) at low pump pulse energies ($\sim$ 4 picojoules). The bright quadratic soliton forms in a low-finesse cavity in both normal and anomalous dispersion regimes, which is in stark contrast with bright Kerr solitons. We present a route to significantly improve the performance of the demonstrated quadratic soliton when extended to an integrated nonlinear platform to realize highly-efficient extreme pulse compression leading to the formation of few-cycle soliton pulses starting from ultra-low energy picosecond scale pump pulses that are widely tunable from ultra-violet to mid-infrared spectral regimes.
Tests of stellar model atmospheres by optical interferometry III: NPOI and VINCI interferometry of the M0 giant gamma Sge covering 0.5 - 2.2 microns

description: Aims: We present a comparison of the visual and NIR intensity profile of the M0 giant gamma Sagittae to plane-parallel ATLAS 9 as well as to plane-parallel & spherical PHOENIX model atmospheres. Methods: We use previously described visual interferometric data obtained with the NPOI in July 2000. We apply the recently developed technique of coherent integration, and thereby obtain visibility data of more spectral channels and with higher precision than before. In addition, we employ new measurements of the K-band diameter of gamma Sagittae obtained with the instrument VINCI at the VLTI in 2002. Results: The spherical PHOENIX model leads to a precise definition of the Rosseland angular diameter and a consistent high-precision diameter value for our NPOI and VLTI/VINCI data sets of Theta_Ross=6.06 pm 0.02 mas, with the Hipparcos parallax corresponding to R_Ross=55 pm 4 R_sun, and with the bolometric flux corresponding to an effective temperature T_eff=3805 pm 55 K. Our visual visibility data close to the first minimum and in the second lobe constrain the limb-darkening effect and are generally consistent with the model atmosphere predictions. The visual closure phases exhibit a smooth transition between 0 and pi. Conclusions: The agreement between the NPOI and VINCI diameter values increases the confidence in the model atmosphere predictions from optical to NIR wavelengths as well as in the calibration and accuracy of both interferometric facilities. The consistent night-by-night diameter values of VINCI give additional confidence in the given uncertainties. The closure phases suggest a slight deviation from circular symmetry, which may be due to surface features, an asymmetric extended layer, or a faint unknown companion.

description: During the current pandemic, colleges are at the fork to either open the campus and curb the spread of COVID-19 or go virtual and risk their efficiency and finally give into financial ruin. This study explores learners’ perceptions of engagement in an online environment to curtail online courses. How educators and students socially interact in cyberspace is a long-standing research topic. Several researchers explored online engagement in higher education in multiple studies (e.g., Kahu, 2011; Ross, 2010). However, there is a lack of research that explores preservice teachers’ engagement in English for speakers of other languages (ESOL) courses. We focused on preservice ESOL teachers’ perceptions of engagement in online discussions to uncover factors that could contribute to increasing their engagement. We collected the data through an online survey, student interviews, and recording online asynchronous discussion transcripts. Constant comparative analysis of data indicated a safe, non-threatening atmosphere as well as a sense of confirmation, and exploring new aspects of the topic; factors that reassured the engagement of the participants.

description: We present the detection of the reactive ion CO+ towards the prototypical starburst galaxy M82. This is the first secure detection of this short-lived ion in an external galaxy. Values of [CO+]/[HCO+]>0.04 are measured across the inner 650pc of the nuclear disk of M82. Such high values of the [CO+]/[HCO+] ratio had only been previously measured towards the atomic peak in the reflection nebula NGC7023. This detection corroborates that the molecular gas reservoir in the M82 disk is heavily affected by the UV radiation from the recently formed stars. Comparing the column densities measured in M82 with those found in prototypical Galactic photon-dominated regions (PDRs), we need \~20 clouds along the line of sight to explain our observations. We have completed our model of the molecular gas chemistry in the M82 nucleus. Our PDR chemical model successfully explains the [CO+]/[HCO+] ratios measured in the M~82 nucleus but fails by one order of magnitude to explain the large measured CO+ column densities (~1--4x10^{13} cm^{-2}). We explore possible routes to reconcile the chemical model and the observations.

description: We give a basic explanation for the oscillating properties of some physical quantities of a two-electron quantum dot in the presence of a static magnetic field. This behaviour was discussed in a previous work of ours [AM Maniero, {\it et al}. J. Phys. B: At. Mol. Opt. Phys. 53:185001, 2020] and was identified as a manifestation of the {\it de Haas-van Alphen} effect, originally observed in the framework of diamagnetism of metals in the 30's. We show that this behaviour is a consequence of different eigenstates of the system assuming, in a certain interval of the magnetic field, the condition of the lowest energy singlet and triplet states.

Using Virtual Exchange to Foster Global Competence and Collaborative Leadership in Teacher Education

Publisher: name: Dual Language Research and Practice Journal
Year: 2021

description: Virtual exchange is a technology enhanced educational platform that makes it possible to connect classrooms and educators across geographic borders. Often also referred to as ‘telecollaboration’ and other variation, virtual exchange offers educators opportunities to collaborate with other teacher educators cross culturally in their efforts to engage a classroom of diverse leaners. Around the globe, educators seek to combine virtual exchange and innovative pedagogy to transform classrooms into dynamic places to teach and learn. Despite the positive comments that have been reaped on the pedagogical potential of virtual exchange programs, virtual exchange has not been successfully mainstreamed into formal curriculum and made into a staple of educational practices in p-12 schools. Consequently, few studies exist to explore the implications of incorporating virtual exchange into formal learning settings where the curriculum is in dire need for instructional innovation in order to move education into the 21st century. This paper presents a study in which virtual exchange is used as an authentic context to expand TESOL teacher candidates’ teaching and collaborative repertoire. TESOL teacher candidates worked in pair, taking turns between facilitating students in cross interaction and chronicling fieldnotes on student engagement. Candidates’ reflective journals and student interviews are used to collect data for this study. Practices and challenges in incorporating virtual exchange into the standards aligned classroom were explored and discussed.

description: Capturing non-Markovian dynamics of open quantum systems is generally a challenging problem, especially for strongly-interacting many-body systems. In this work, we combine recently developed non-Markovian quantum state diffusion techniques with tensor network methods to address this challenge. As a first example, we explore a Hubbard-Holstein model with dissipative phonon modes, where this new approach allows us to quantitatively assess how correlations spread in the presence of non-Markovian dissipation in a 1D many-body system. We find regimes where correlation growth can be enhanced by these effects, offering new routes for dissipatively enhancing transport and correlation spreading, relevant for both solid state and cold atom experiments.

description: Student evaluations of online classes are frequently lower than their face-to-face counterparts, and one of the most common explanations students provide for poor online class evaluations is a lack of communication. One phenomenon that has been shown to improve communication as well as learning outcomes is positive interdependence, the collaborative – not competitive – reliance of student group members on each other in order to achieve mutual group success. Not only does collaborative learning encourage better participation and learning outcomes, but it offers a more natural learning style for students from collectivist cultures than the independent learning environment that online courses often provide. This makes the community of inquiry framework, which values social, teaching, and cognitive presences, appropriate when designing online teaching and learning environments for English learners. However, in a synchronous chat-based online class, social presence may manifest differently than in asynchronous text-based online classes. This paper presents a single qualitative case study of a synchronous online English for Academic Purposes class for Chinese high school students. The study introduces and evaluates the presence of indicators of social presence among the students in an especially non-communicative group. Findings and implications for future research and practice of social presence in collaborative learning environments in online English for Academic Purposes classes are discussed.

Technology-Enhanced Language Education Revisited: A Developmental Perspective
Creators: name: Khoshnevisan, Babak
Publisher: name: Dual Language Research and Practice Journal
Year: 2021

description: The traditional landscape of education has been widely inundated with an array of technologies and technological tools in recent decades. Technology, if effectively integrated, offers promises to unleash the learners’ full potentials. Multiple researchers have explored the perceptions of language educators and learners alike (e.g., Cheng & Tsai, 2014; Cheng & Tsai, 2016; Author, 2019a). Other researchers have investigated the role of technology on the cognitive achievement of language learners in different language skills. Author (2019a) reiterates that the common thread amongst tools harnessed in technology-enhanced language education is that technology, by and large, enhances comprehension, increases cognitive attainment and motivation level of learners. Research findings imply that technologies exploited in language learning not only motivate learners but also serve as a catalyst in the language learning process (Singhal, Bagga, Goyal, & Saxena, 2012; Ibáñez, Di Serio, Villarán, & Kloos, 2014). Beginning with a chronological review of the advent of technology in the realm of language education, this article will present contradictory, yet scholarly, opinions of researchers documented and corroborated with empirical research concerning the use of technology in language education. To achieve that, the author will embark on detailing how technology affords language teachers. The backbone of the article is an evidence-based discussion regarding the motivational factors ensued by technologies. Having scrutinized the role of technology in language education, the author will delineate technologies recently employed to increase the motivation level of students. This article will also discuss the constraints of technology and shed light on potential challenges that both language educators and learners may encounter including educators’ lack of knowledge about technology and limitations of technologies.

description: In complex crystals close to melting or at finite temperatures, different types of defects are ubiquitous and their role becomes relevant in the mechanical response of these solids. Conventional elasticity theory fails to provide a microscopic basis to include and account for the motion of point-defects in an otherwise ordered crystalline structure. We study the elastic properties of a point-defect rich crystal within a first-principles theoretical framework derived from microscopic equations of motion. This framework allows us to make specific predictions pertaining to the mechanical properties which we can validate through deformation experiments performed in Molecular Dynamics simulations.

Asymptotic completeness via Mourre theory of a Schrödinger operator on a binary tree grap
Creators: name: Allard, Christine Shirley
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is divided as follows: The first chapter introduces the main ideas intuitively while assuming an acquaintance with quantum mechanics. The second chapter exposes the mathematical setting of the problem under investigation and contains a brief excursion into self-adjointness of unbounded operators. The core of the thesis is contained in the third chapter where a conjugate operator A is defined in order that the Mourre estimate for the discrete Hamiltonian H = L + Q is shown to hold for a binary tree configuration space, where L is the discrete Laplacian and Q a discrete potential either of short-range type or of long-range type satisfying a first order difference condition. In the last chapter the result from chapter three as well as some extra material is used to show that asymptotic completeness holds for a one-body system having a binary tree configuration space with either of the following three types of potential: 1) long-range potentials satisfying first and second order difference conditions 2) short-range potentials of order o(|v|⁻¹) and satisfying a second order difference condition or 3) short-range potentials of order o(|v|⁻²).

A survey of boundary element methods for a two-dimensional fracture model
Creators: name: James, Douglas L.
Publisher: name: University of British Columbia
Year: 2009

description: This thesis surveys boundary element methods for solving a two-dimensional pressurized line crack problem in a homogeneous infinite elastic medium. Starting with an overview of linear elastic fracture mechanics, the exact solution to the pressurized line crack problem is stated and results for several pressure distributions are provided. Various numerical methods for solving the crack problem are then introduced, such as the displacement discontinuity method (DDM) using point collocation and a Galerkin method. Crack tip elements and higher-order DDM are discussed. Self-effect correction methods, stated and developed for the piecewise constant DDM on a uniform grid, are shown to significantly improve the numerical solution. An accurate DDM correction for modelling crack tip element extensions is also presented. Finally, numerical results for the various methods are given and stress intensity factors are also presented for comparison.

description: Sub-wavelength electromagnetic field localization has been central in photonic research in the last decade, allowing to enhance sensing capabilities as well as increasing the coupling between photons and material excitations. The ultrastrong light-matter coupling regime in the THz range with split-ring resonators coupled to magnetoplasmons has been widely investigated, achieving successive world-records for the largest light-matter coupling ever achieved. Ever shrinking resonators have allowed to approach the regime of few electrons strong coupling, in which single-dipole properties can be modified by the vacuum field. Here we demonstrate, theoretically and experimentally, the existence of a limit to the possibility of arbitrarily increasing electromagnetic confinement in polaritonic systems. Strongly sub-wavelength fields can excite a continuum of high-momenta propagative magnetoplasmons. This leads to peculiar nonlocal polaritonic effects, as certain polaritonic features disappear and the system enters in the regime of bound-to-continuum strong coupling. Emerging nonlinearities due to the local breaking of Kohn's theorem are also reported.

Bayesian Comparison of GARCH Processes with Skewnes Mechanism in Conditional Distributions

description: The main goal of this paper is an application of Bayesian model comparison, based on the posterior probabilities and posterior odds ratios, in testing the explanatory power of the set of competing GARCH (ang. Generalised Autoregressive Conditionally Heteroscedastic) specifications, all with asymmetric and heavy tailed conditional distributions. In building competing volatility models we consider, as an initial specification, GARCH process with conditional Student-t distribution with unknown degrees of freedom parameter, proposed by Bollerslev (1987). By introducing skewness into Student-t family and incorporating the resulting class as a conditional distribution we generated various GARCH models, which compete in explaining possible asymmetry of both conditional and unconditional distribution of financial data. Based on the daily returns of hypothetical financial time series, we discuss the results of Bayesian comparison of alternative skewing mechanisms applied in the initial Student-t GARCH framework. We also check the sensitivity of model ranking with respect to the changes in prior distribution of model specific parameters. Additionally, we present formal Bayesian inference about conditional asymmetry of the distribution of the daily returns in all competing specifications on the basis of the skewness measure defined by Arnold and Groenveld (1995).

The Ising phase in the J1-J2 Heisenberg Model

description: The two dimensional Heisenberg antiferromagnet on the square lattice with nearest (J1) and next-nearest (J2) neighbor couplings is investigated in the strong frustration regime (J2/J1>1/2). A new effective field theory describing the long wavelength physics of the model is derived from the quantum hamiltonian. The structure of the resulting non linear sigma model allows to recover the known spin wave results in the collinear regime, supports the presence of an Ising phase transition at finite temperature and suggests the possible occurrence of a non-magnetic ground state breaking rotational symmetry. By means of Lanczos diagonalizations we investigate the spin system at T=0, focusing our attention on the region where the collinear order parameter is strongly suppressed by quantum fluctuations and a transition to a non-magnetic state occurs. Correlation functions display a remarkable size independence and allow to identify the transition between the magnetic and non-magnetic region of the phase diagram. The numerical results support the presence of a non-magnetic phase with orientational ordering.

description: Order-disorder transitions are widely explored in various vortex structures in condensed matter physics, i.e., in the type-II superconductors and Bose-Einstein condensates. In this study, we have investigated the ordering of the polar vortex phase in the (PZT)n/(STO)n superlattice systems through phase-field simulations. An antiorder state is discovered for short periodicity superlattice on an SSO substrate, owing to the huge interfacial coupling between PZT and STO as well as the giant in-plane polarization in STO layers due to the large tensile strain. Increasing the periodicity leads to the anti-order to disorder transition, resulting from the loss of interfacial coupling and disappearance of the polarization in STO layers. On the other hand, for short periodicity superlattices, order-disorder-antiorder transition can be engineered by mediating the substrate strain, due to the delicate competition between the depoling effect, interfacial coupling, and strain effect. We envision this study to spur further interest towards the understanding of order-disorder transition in ferroelectric topological structures.

Surface roughness influence on the quality factor of high frequency nanoresonators

description: Surface roughness influences significantly the quality factor of high frequency nanoresonators for large frequency - relaxation times within the non-Newtonian regime, where a purely elastic dynamics develops. It is shown that the influence of sort wavelength roughness, which is expressed by the roughness exponent H for the case of self-affine roughness, plays significant role in comparison with the effect of the long wavelength roughness parameters such as the rms roughness amplitude and the lateral roughness correlation length. Therefore, the surface morphology can play important role in designing high-frequency resonators operating within the non-Newtonian regime.

The Role of Solid Friction in the Sedimentation of Strongly Attractive Colloidal Gels

description: We study experimentally and theoretically the sedimentation of gels made of strongly aggregated colloidal particles, focussing on the long time behavior, when mechanical equilibrium is asymptotically reached. The asymptotic gel height is found to vary linearly with the initial height, a finding in stark contrast with a recent study on similar gels [Manley \textit{et al.} 2005 \textit{Phys. Rev. Lett.} \textbf{94} 218302]. We show that the asymptotic compaction results from the balance between gravity pull, network elasticity, and solid friction between the gel and the container walls. Based on these ingredients, we propose a simple model to account for the dependence of the height loss on the initial height and volume fraction. As a result of our analysis, we show that the static friction coefficient between the gel and the container walls strongly depends on volume fraction: the higher the volume fraction, the weaker the solid friction. This nonintuitive behavior is explained using simple scaling arguments.
