description: We give a novel and simple proof of the DFT expression for the interatomic force field that drives the motion of atoms in classical Molecular Dynamics, based on the observation that the ground state electronic energy, seen as a functional of the external potential, is the Legendre transform of the Hohenberg-Kohn functional, which in turn is a functional of the electronic density. We show in this way that the so-called Hellmann-Feynman analytical formula, currently used in numerical simulations, actually provides the exact expression of the interatomic force.

Boundary condition and reflection anomaly in $2+1$ dimensions

description: It is known that the $2+1$d single Majorana fermion theory has an anomaly of the reflection, which is canceled out when 16 copies of the theory are combined. Therefore, it is expected that the reflection symmetric boundary condition is impossible for one Majorana fermion, but possible for 16 Majorana fermions. In this paper, we consider a reflection symmetric boundary condition that varies at a single point, and find that there is a problem with one Majorana fermion. The problem is the absence of a corresponding outgoing wave to a specific incoming wave into the boundary, which leads to the non-conservation of the energy. For 16 Majorana fermions, it is possible to connect every incoming wave to an outgoing wave without breaking the reflection symmetry. In addition, we discuss the connection with the fermion-monopole scattering in $3+1$ dimensions.

description: The grand architecture of nature can be seen at play in a tree: no two are alike. Nevertheless, there is an inescapable similarity that makes us identify a tree anywhere in the world. Just saying “tree” recalls words like green, root, leaves, still, strong, branches. The tree of primitive Pythagorean triples is no different (Figure 1). It has a root, or a beginning. It is rooted not on earth, but on the soil of our mind. It has branches that spring from that root as it grows with the action of nature and time. In this case, it is not the proverbial Mother Nature, but the human nature — a nature formed by the human interpretation of reality. The Pythagoras’ tree presented by Berggren in 1934 has stood still and strong for almost a century, but probably it is even older. Its leaves are triples, and they grow throughout its branches. Ultimately, when one looks at the Pythagoras’ tree, one looks at a ‘tree’. The root is the triple (3, 4, 5). All branches and leafs emerge from, and are dependent, of this root. Like any tree, all it requires is a seed and soil, and all develops automatically. The architecture that defines the tree is present throughout the tree and is a reflection of the beginning — the root. In other words, the root (3, 4, 5) plus the same movement repeated over and over again creates the tree. In this paper, we will look at how this basic geometrical and mathematical movement governs the birth and growth of the Pythagoras’ tree. Pythagoras is included in secondary education around the world including in Australian Curriculum (ACARA, n.d.), and hence this paper will be of interest to all.

description: The triangles formed by the triples in Pythagoras’ or Plato’s families can be geometrically interconnected via intermediate central squares—this forms the basis of the central square theory. This pattern of parent–child triple relationship allowed the geometric construction of both sequences, which seem to behave in a similar manner. Governed solely by specific increments in the smaller side of the triple and the identified geometrical pattern, it has been shown that both sequences start with the first triple (3, 4, 5), revolving around a square of side length unit, and evolve outwards into infinity. From the perspective of central square theory, the Pythagoras’ or Plato’s families are expressed not only as a sequence of triples, but also by their connecting sequence of squares.

A Multilayered Approach to Researching Learner Agency as Complex Dynamic System: Cases of Japanese Students Learning English at University
Creators: name: Nitta, Ryo

Publisher: name: International Journal of Complexity in Education
Year: 2023

description: This study explored how university students develop their agency in language learning from the perspective of Complex Dynamic Systems Theory. Learner agency refers to the feeling of ownership and sense of control that learners have over their learning (Larsen-Freeman, et al., 2021). Learner agency has been increasingly recognized as a dynamic and complex construct characterized as “relational, emergent, spatially, and temporally situated” (Larsen-Freeman, 2019, p. 73). We used a multilayered approach to investigate how learner agency emerged and evolved by focusing on three psychosocial layers: dispositional traits, characteristic adaptations, and narrative identity (Dörnyei Ryan, 2015). We observed two individual students in an English class at the university. Data were collected over 30 weeks using the Motivational Factors Questionnaire, self-reflective comments written in their first language, and second language writing, each targeting the three layers. Their reflections illustrated how their engagement in the classroom task contributed to their sustained motivation and the emergence of learner agency over the year. In the analysis of the students’ written narratives of their critical episodes, we identified recurring common themes, long-term career goals and immediate learning experiences with specific episodes showing the uniqueness of their subjective experiences outside the classroom. Integrating their past, present, and future states led to an emergent sense of agency. The synthesis of the three layers of the two students revealed that having a sense of interconnectedness of various components became the basis for learner agency. This study also offers insights into the methodology for researching the dynamics and complexity of learner agency in a wider sociohistorical context. Keywords: complex dynamic systems theory, multilayered approach, learner agency, language learning motivation

description: The Mid-Infrared Instrument (MIRI) for the {\em James Webb Space Telescope} (JWST) will revolutionize our understanding of infrared stellar populations in the Local Volume. Using the rich {\em Spitzer}-IRS spectroscopic data-set and spectral classifications from the Surveying the Agents of Galaxy Evolution (SAGE)-Spectroscopic survey of over a thousand objects in the Magellanic Clouds, the Grid of Red supergiant and Asymptotic giant branch star ModelS ({\sc grams}), and the grid of YSO models by Robitaille et al. (2006), we calculate the expected flux-densities and colors in the MIRI broadband filters for prominent infrared stellar populations. We use these fluxes to explore the {\em JWST}/MIRI colours and magnitudes for composite stellar population studies of Local Volume galaxies. MIRI colour classification schemes are presented; these diagrams provide a powerful means of identifying young stellar objects, evolved stars and extragalactic background galaxies in Local Volume galaxies with a high degree of confidence. Finally, we examine which filter combinations are best for selecting populations of sources based on their JWST colours.

Change in Degree vs. Change in Kind: Bridging the Quantitative/Qualitative Divide in Second Language Fluency placeholder text
Creators: name: Evans, Reid
Publisher: name: International Journal of Complexity in Education
Year: 2023

description: The present study investigated the development of second language fluency from the perspective of complex dynamic systems theory in an un-tutored adult learner of English as a second language. To complement traditional studies of second language (L2) utterance fluency, this study adopted a functional, usage-based perspective and sought to understand how fluency changes not just in terms of numerical increases or decreases in the frequency of disfluency features, but also how the discursive function of fluency changes over time. Data were collected from two oral tasks on a weekly basis for one academic year and were analyzed quantitatively and qualitatively in an attempt to achieve dynamic method integration (Hiver Al-Hoorie, 2020). Though many disfluency features demonstrated either stagnation or even increases in frequency over the period of data collection, the way in which these features were leveraged by the learner changed over time. Specifically, pause clusters and self-repair acquired new roles associated with the emergence, and the subsequent monitor and repair, of novel syntactic structures. Results suggest that understanding L2 utterance fluency development is complex and requires more than simple frequency counts of disfluency features. Instead, definitions of L2 fluency must account for the discursive function of disfluencies and how these functions change as speakers develop proficiency in the L2.

description: Pedagogical translanguaging, the planned, deliberate, and flexible use of two or more languages in the same lesson, is a highly recommended practice in the foreign language (L2) classroom, but thus far there are no quantitative empirical studies supporting translanguaging behavior. To analyze the use of translanguaging, the present study analyzed L2 classroom interaction in 39 lessons in 2594 pairs of teacher questions and student answers, zooming in on the trade-off between (a) getting an answer and (b) getting an answer in the L2. A cluster analysis identified four types of lessons: (1) mainly L2 - low L2 response, (2) mainly L2 - high L2 response, (3) mainly L1 - low L2 response and (4) L2-L1 translanguagers – moderately high L2 response. Comparing cluster (1) in which teachers spoke English exclusively and students gave minimal responses in the L2 to cluster (2) in which teacher also used English exclusively but obtained high levels of L2 response from the learners, reveals mixed outcomes when teachers adopt a monolingual stance (L2 only as the language of instruction). Lessons in cluster 4, the “translanguagers,” reveal a significantly higher level of student responsiveness. This implies that teachers who ask many questions in the L2, but receive few answers, may increase students’ active classroom participation by adopting pedagogical translanguaging. A possible interpretation of the outcomes of this study is that using the foreign language as the language of instruction and pedagogical translanguaging are complementary, rather than competing, strategies in a language teacher’s repertoire. Keywords: interaction, translanguaging, time-series analyses, teaching-learning process, heuristic.

description: Tired of food debris blocking your kitchen sink? We all are, making this an excellent opportunity to look at novel ways to manage the dirty water outflow (often carrying clutering debris).This multi-path strainer accommodates design features that store food debris in special 360 degree cavities, while preveting complete blockage. The horizontal water path is the primary way to carry water to the outlet, whilst preventing debris from blocking completely the water flow. If this horizontal path gets blocked (by soo much debris that covers the entire 360 degrees of cavities), water will accummulate and overflow via the vertical path, providing an alternative means of discharge, and thus preventing overall blockage of the sink.This article explains the design process of a novel manner of managing the water flow from a sink in order to prevent, or at least minimize, its blockage (due to singularity convergence of debris, which often happens when we are washing dishes).The CAD model is available for download from Figshare here.This research was originally published as an article on the Open Design Magazine hosted by the MIT PubPub open source publication platform.-------------------------------------------------------------------------For more public data, please visit my Figshare profile: https://figshare.com/authors/Luis_Teia/10811244

description: Quantum correlations are a fundamental property of quantum many-body states. Yet they remain experimentally elusive, hindering certification of genuine quantum behavior, especially in quantum materials. Here we show that the momentum-dependent dynamical susceptibility measured via inelastic neutron scattering enables the systematic reconstruction of a general family of quantum correlation functions, which express the degree of quantum coherence in the fluctuations of two spins at arbitrary mutual distance. Using neutron scattering data on the compound KCuF$_3$ $\unicode{x2014}$ a system of weakly coupled $S=1/2$ Heisenberg chains $\unicode{x2014}$ and of numerically exact quantum Monte Carlo data, we show that quantum correlations possess a radically different spatial structure with respect to conventional correlations. Indeed, they exhibit a new emergent length scale $\unicode{x2014}$ the quantum coherence length $\unicode{x2014}$ which is finite at any finite temperature (including when long-range magnetic order develops). Moreover, we show theoretically that coupled Heisenberg spin chains exhibit a form of quantum monogamy, with a trade-off between quantum correlations along and transverse to the spin chains. These results highlight real-space quantum correlators as an informative, model-independent means of probing the underlying quantum state of real quantum materials.

Educational Landscapes Through a Complexity Theory Lens: Using System Mapping to Investigate L2 Shakespeare Studies in Secondary Schools
Creators: name: Fogal, Gary G.
Publisher: name: International Journal of Complexity in Education
Year: 2023

description: Research interest in Shakespeare studies in mainstream English literature classrooms is a constant (Keilen Moschovakis, 2017). However, outside limited geographic regions of study (e.g., Germany), little is known about how Shakespeare is used to aid second language (L2) development—despite the ubiquitous attention Shakespeare’s works receive in L2 learning environments (Eisenmann Lütge, 2014). To address this gap, this study employs complex dynamic systems theory as an explanatory framework and adopts a system mapping approach (Fogal, 2022; Ludlow et al., 2017) to investigate how relevant stakeholders are seen to view Shakespeare studies as a tool for mediating L2 development across the teaching, learning, and administrative landscapes of a set of secondary schools in the Canadian province of Ontario. Findings describe stakeholders’ views as variegated and outline meaningful differences in how constituent groups interpret L2 Shakespeare studies. This work outlines recommendations for steering change that may foster L2 learning and initiates an agenda for continued research into how best to operationalize Shakespeare studies in ways that foster co-adaptive and emergent processes in the service of localized educational contexts. This study appeals to education scholars curious about the value of complex dynamic systems theory, L2 researchers interested in how literary studies can assist L2 learning, and instructors and curriculum designers focused on better understanding the landscape of L2 Shakespeare studies (and by extension, L2 literature studies) in the secondary school context.

A Vector type of Unruh-DeWitt-like detector

description: We study a type of an Unruh-DeWitt-like detector based on a vector rather than scalar field. This detector has two energy states and produces Larmor radiation when there is no energy gap between them. This setup indicates that Larmor radiation and Unruh radiation are two counterparts of the same phenomenon. Larmor radiation is observed in the inertial frame, while Unruh radiation is observed in an accelerated frame. The accelerated observer sees that his detector absorbed a particle inside its own accelerated horizon, while the Larmor radiation is the companion particle which leaves the accelerated observer's horizon. Since the detection is based on the electromagnetic field, this type of detector is much closer to the real world than a standard Unruh-DeWitt detector which is coupled to a scalar field.

Unfortunately, many existing frameworks are either expensive, non-portable, or require complex room preparation. Therefore, a simple, flexible, portable, and low-cost teleoperation system based on optical motion tracking with fiducial markers for robotic arm systems is presented. Interfaces to wear the optical markers on the operator’s body and an algorithm to increase robustness by switching between multiple markers have been developed.

description: Hybrid density functional calculations are performed for a variety of systems containing d9 ions (Cu2+, Ag2+), and exhibiting quasi-one-dimensional magnetic properties. In particular we study fluorides containing these ions in a rarely encountered compressed octahedral coordination which forces the unpaired electron in the d(z2) orbital. We predict that such systems should exhibit magnetic anisotropies surpassing that of Sr2CuO3 - one of the best realizations of an one-dimensional system known to date. In particular we predict that the inter-chain coupling in the Ag2+ containing [AgF][BF4] should be nearly five orders of magnitude smaller than the intra-chain interaction. Our results indicate that quasi-one-dimensional spin-1/2 systems containing chains with spin sites in a d(z2)1 local ground state could constitute a versatile model for testing modern theories of quantum many-body physics in the solid state.

description: Aims. To produce an homogeneous catalog of astrophysical parameters of 239 resolved star clusters located in the Small and Large Magellanic Clouds, observed in the Washington photometric system. Methods. The cluster sample was processed with the recently introduced Automated Stellar Cluster Analysis ($\texttt{ASteCA}$) package, which ensures both an automatized and a fully reproducible treatment, together with a statistically based analysis of their fundamental parameters and associated uncertainties. The fundamental parameters determined with this tool for each cluster, via a color-magnitude diagram (CMD) analysis, are: metallicity, age, reddening, distance modulus, and total mass. Results. We generated an homogeneous catalog of structural and fundamental parameters for the studied cluster sample, and performed a detailed internal error analysis along with a thorough comparison with values taken from twenty-six published articles. We studied the distribution of cluster fundamental parameters in both Clouds, and obtained their age-metallicity relationships. Conclusions. The $\texttt{ASteCA}$ package can be applied to an unsupervised determination of fundamental cluster parameters; a task of increasing relevance as more data becomes available through upcoming surveys.

description: We consider a family of $(2,2)$-rational functions given on the set of complex $p$-adic field $\mathbb{C}_p$. Each such function has a unique fixed point. We study $p$-adic dynamical systems generated by the $(2,2)$-rational functions. We show that the fixed point is indifferent and therefore the convergence of the trajectories is not the typical case for the dynamical systems. Siegel disks of these dynamical systems are found. We obtain an upper bound for the set of limit points of each trajectory, i.e., we determine a sufficiently small set containing the set of limit points. For each $(2,2)$-rational function on $\mathbb{C}_p$ there are two points $\hat x_1=\hat x_1(f)$, $\hat x_2=\hat x_2(f)\in \mathbb{C}_p$ which are zeros of its denominator. We give explicit formulas of radiuses of spheres (with the center at the fixed point) containing some points such that the trajectories (under actions of $f$) of the points after a finite step come to $\hat x_1$ or $\hat x_2$. Moreover for a class of $(2,2)$-rational functions we study ergodicity properties of the dynamical systems on the set of $p$-adic numbers $Q_p$. For each such function we describe all possible invariant spheres. We show that the $p$-adic dynamical system reduced on each invariant sphere is not ergodic with respect to Haar measure.

description: We construct a new subsystem code in three dimensions that exhibits single-shot error correction in a user-friendly and transparent way. As this code is a subsystem version of coupled toric codes, we call it the intertwined toric code (ITC). Although previous codes share the property of single-shot error correction, the ITC is distinguished by its physically motivated origin, geometrically straightforward logical operators and errors, and a simple phase diagram. The code arises from 3d stabilizer toric codes in a way that emphasizes the physical origin of the single-shot property. In particular, starting with two copies of the 3d toric code, we add check operators that provide for the confinement of pointlike excitations without condensing the loop excitations. Geometrically, the bare and dressed logical operators in the ITC derive from logical operators in the underlying toric codes, creating a clear relationship between errors and measurement outcomes. The syndromes of the ITC resemble the syndromes of the single-shot code by Kubica and Vasmer, allowing us to use their decoding schemes. We also extract the phase diagram corresponding to ITC and show that it contains the phases found in the Kubica-Vasmer code. Finally, we suggest various connections to Walker-Wang models and measurement-based quantum computation.

description: A quantum particle transport induced in a spatially-periodic potential by a propagating plane wave has a number important implications in a range of topical physical systems. Examples include acoustically driven semiconductor superlattices and cold atoms in optical crystal. Here we apply kinetic description of the directed transport in a superlattice beyond standard linear approximation, and utilize exact path-integral solutions of the semiclassical transport equation. We show that the particle drift and average velocities have non-monotonic dependence on the wave amplitude with several prominent extrema. Such nontrivial kinetic behaviour is related to global bifurcations developing with an increase of the wave amplitude. They cause dramatic transformations of the system phase space and lead to changes of the transport regime. We describe different types of phase trajectories contributing to the directed transport and analyse their spectral content.

In addition to those that have analogs in Topologically Massive Gravity, such as warped AdS and pp-waves, there are several solutions genuine to MMG. Among them, there is a stationary Lifshitz metric with the dynamical exponent z=-1 and an anisotropic Lifshitz solution where all coordinates scale differently. Moreover, we identify a homogeneous Kundt type solution at the chiral point of the theory. We also show that in a particular limit of the physical parameters in which the Cotton tensor drops out from the MMG field equation, homogeneous solutions exist only at the merger point in the parameter space if they are not conformally flat.

description: Gravitational waves from inflation induce polarization patterns in the cosmic microwave background (CMB). It is known that there are only two types of non-Gaussianities of the gravitaional waves in the most general scalar field theories having second-order field equations. One originates from the inherent non-Gaussianity in general relativity, and the other from a derivative coupling between the Einstein tensor and a kinetic term of the scalar field. We calculate polarization bispectra induced by these non-Gaussianities by transforming them into separable forms by virtue of the Laplace transformation. It is shown that future experiments can detect only the new one if the latter coupling parameter takes an extremely large value, which, however, does not cotradict the current observational data.

description: We propose a new model of quantum computation comprised of low-weight measurement sequences that simultaneously encode logical information, enable error correction, and apply logical gates. These measurement sequences constitute a new class of quantum error-correcting codes generalizing Floquet codes, which we call dynamic automorphism (DA) codes. We construct an explicit example, the DA color code, which is assembled from short measurement sequences that can realize all 72 automorphisms of the 2D color code. On a stack of $N$ triangular patches, the DA color code encodes $N$ logical qubits and can implement the full logical Clifford group by a sequence of two- and, more rarely, three-qubit Pauli measurements. We also make the first step towards universal quantum computation with DA codes by introducing a 3D DA color code and showing that a non-Clifford logical gate can be realized by adaptive two-qubit measurements.

description: Measurements of the charge-dependent two-particle angular correlation function in proton-lead (pPb) collisions at a nucleon-nucleon center-of-mass energy of $\sqrt{s_\mathrm{NN}}$ = 8.16 TeV and lead-lead (PbPb) collisions at $\sqrt{s_\mathrm{NN}}$ = 5.02 TeV are reported. The pPb and PbPb data sets correspond to integrated luminosities of 186 nb$^{-1}$ and 0.607 nb$^{-1}$, respectively, and were collected using the CMS detector at the CERN LHC. The charge-dependent correlations are characterized by balance functions of same- and opposite-sign particle pairs. The balance functions, which contain information about the creation time of charged particle pairs and the development of collectivity, are studied as functions of relative pseudorapidity ($Δη$) and relative azimuthal angle ($Δϕ$), for various multiplicity and transverse momentum ($p_\mathrm{T}$) intervals. A multiplicity dependence of the balance function is observed in $Δη$ and $Δϕ$ for both systems. The width of the balance functions decreases toward high-multiplicity collisions in the momentum region $\lt$ 2 GeV, for pPb and PbPb results. Integrals of the balance functions are presented in both systems, and a mild dependence of the charge-balancing fractions on multiplicity is observed. No multiplicity dependence is observed at higher transverse momentum. The data are compared with HYDJET, HIJING and AMPT generator predictions, none of which capture completely the multiplicity dependence seen in the data. The comparison of results with different center-of-mass energies suggest that the balance functions become narrower at higher energies, which is consistent with the idea of delayed hadronization and the effect of radial flow.

description: We describe a Markov chain Monte Carlo method to approximately simulate a centered d-dimensional Gaussian vector X with given covariance matrix. The standard Monte Carlo method is based on the Cholesky decomposition, which takes cubic time and has quadratic storage cost in d. In contrast, the storage cost of our algorithm is linear in d. We give a bound on the quadractic Wasserstein distance between the distribution of our sample and the target distribution. Our method can be used to estimate the expectation of h(X), where h is a real-valued function of d variables. Under certain conditions, we show that the mean square error of our method is inversely proportional to its running time. We also prove that, under suitable conditions, our method is faster than the standard Monte Carlo method by a factor nearly proportional to d. A numerical example is given.

description: To contribute to automating the medical vision-language model, we propose a novel Chest-Xray Difference Visual Question Answering (VQA) task. Given a pair of main and reference images, this task attempts to answer several questions on both diseases and, more importantly, the differences between them. This is consistent with the radiologist's diagnosis practice that compares the current image with the reference before concluding the report. We collect a new dataset, namely MIMIC-Diff-VQA, including 700,703 QA pairs from 164,324 pairs of main and reference images. Compared to existing medical VQA datasets, our questions are tailored to the Assessment-Diagnosis-Intervention-Evaluation treatment procedure used by clinical professionals. Meanwhile, we also propose a novel expert knowledge-aware graph representation learning model to address this task. The proposed baseline model leverages expert knowledge such as anatomical structure prior, semantic, and spatial knowledge to construct a multi-relationship graph, representing the image differences between two images for the image difference VQA task. The dataset and code can be found at https://github.com/Holipori/MIMIC-Diff-VQA. We believe this work would further push forward the medical vision language model.

description: In recent years, automation has gained increasing importance and is nowadays also applied in the healthcare sector in the field of rehabilitation. Through the implementation of automation technologies, it is possible to alleviate the continuously increasing workload of healthcare personnel and tackle the prevailing staff shortage. Simultaneously, it allows for the improvement of therapy outcomes by ensuring the desired frequency and duration of treatment. Stroke is considered a prevalent condition affecting a growing number of individuals. Paralysis and functional loss of the upper extremities are potential sequelae. Current automated solutions for post stroke therapy are often characterized by high costs and weight, and due to the complexity of the devices, most can only be operated by specifically trained individuals. To provide accessibility for a more significant number of affected patients, a compact and affordable therapy device for home use is being developed. For this development, a profound understanding of physiologically accurate movement patterns is essential. Therefore, gripping movements were recorded with the assistance of therapists using a high-speed 3D camera system. From the recordings, parameterizable polynomials for the movement velocity of the arm and the hand’s aperture were created based on a few input parameters, such as the diameter and position of the object to be gripped. This leads to a higher level of authenticity compared to using arbitrary linear profiles. To facilitate these movement patterns, the device has been divided into hand and arm unit, authentically recreating a gripping motion through synchronous movement. In terms of the business model, the prevailing tendency is shifting towards the utilization of Product-Service Systems, where the product is rented or monetized based on the results, rather than being purchased. In the context of rehabilitation, the results are equivalent to the patient's convalescence. To pursue this approach, the therapy device utilizes force and Range of Motion (RoM) measurements to determine the effectiveness of the therapy.

description: We classify and explicitly describe homomorphisms of Verma modules for conformal Galilei algebras $\mathfrak{cga}_\ell(d,{\mathbb C})$ with $d=1$ for any integer value $\ell \in \mathbb{N}$. The homomorphisms are uniquely determined by singular vectors as solutions of certain differential operators of flag type, and identified with specific polynomials arising as coefficients in the expansion of a parametric family of symmetric polynomials into power sum symmetric polynomials.
