description: We test the ability of two unsupervised machine learning algorithms, \textit{EnLink} and Shared Nearest Neighbour (SNN), to identify stellar groupings in the Orion star-forming complex as an application to the 5-dimensional astrometric data from \textit{Gaia} DR2. The algorithms represent two distinct approaches to limiting user bias when selecting parameter values and evaluating the relative weights among astrometric parameters. \textit{EnLink} adopts a locally adaptive distance metric and eliminates the need of parameter tuning through automation. The original SNN relies only on human input for parameter tuning so we modified SNN to run in two stages. We first ran the original SNN 7,000 times, each with a randomly generated sample according to within-source co-variance matrices provided in \textit{Gaia} DR2 and random parameter values within reasonable ranges. During the second stage, we modified SNN to identify the most repeating stellar groups from 25,798 we obtained in the first stage. We reveal 21 spatially- and kinematically-coherent groups in the Orion complex, 12 of which previously unknown. The groups show a wide distribution of distances extending as far as about 150 pc in front of the star-forming Orion molecular clouds, to about 50 pc beyond them where we find, unexpectedly, several groups. Our results expose to view the wealth of sub-structure in the OB association, within and beyond the classical Blaauw Orion OBI sub-groups. A full characterization of the new groups is of the essence as it offers the potential to unveil how star formation proceeds globally in large complexes such as Orion.

description: The partition function of the six-vertex model on a square lattice with domain wall boundary conditions (DWBC) is rewritten as a hermitean one-matrix model or a discretized version of it (similar to sums over Young diagrams), depending on the phase. The expression is exact for finite lattice size, which is equal to the size of the corresponding matrix. In the thermodynamic limit, the matrix integral is computed using traditional matrix model techniques, thus providing a complete treatment of the bulk free energy of the six-vertex model with DWBC in the different phases. In particular, in the anti-ferroelectric phase, the bulk free energy and a subdominant correction are given exactly in terms of elliptic theta functions.

description: Little is known about local and systemic biomarkers in relation to synovitis and pain in end-stage osteoarthritis (OA) patients. We investigated the associations between the novel extracellular matrix biomarker, C1M, and local and systemic interleukin 6 (IL-6) with synovitis and pain. Serum C1M, plasma and synovial fluid IL-6 (p-IL-6, sf-IL-6) were measured in 104 end-stage knee OA patients. Contrast-enhanced magnetic resonance imaging (MRI) was used to semi-quantitatively assess an 11-point synovitis score; pain was assessed by the Western Ontario & McMaster Universities Osteoarthritis Index (WOMAC) and the Neuropathic Pain Questionnaire (NPQ). Linear regression was used to investigate associations between biomarkers and synovitis, and biomarkers and pain while controlling for age, sex and body mass index. We also tested whether associations between biomarkers and pain were confounded by synovitis. We found sf-IL-6 was associated with synovitis in the parapatellar subregion (B=0.006; 95% CI 0.003-0.010), and no association between p-IL-6 and synovitis. We also observed an association between C1M and synovitis in the peri-ligamentous subregion (B=0.013; 95% CI 0.003-0.023). Further, sf-IL-6, but not p-IL-6, was significantly associated with pain, WOMAC (B=0.022; 95% CI 0.004-0.040) and NPQ (B=0.043;95% CI 0.005-0.082). There was no association between C1M and WOMAC pain but we did find an association between C1M and NPQ (B=0.229; 95% CI 0.036-0.422). Lastly, synovitis explained both biomarker-NPQ associations, but not the biomarker-WOMAC association. These results suggest C1M and IL-6 are associated with synovitis and pain, and synovitis is an important confounding variable when studying biomarkers and neuropathic features in OA patients.

description: We exhibit a family of dynamical systems arising from rational points on elliptic curves in an attempt to mimic the familiar toral automorphisms. At the non-archimedean primes, a continuous map is constructed on the local elliptic curve whose topological entropy is given by the local canonical height. Also, a precise formula for the periodic points is given. There follows a discussion of how these local results may be glued together to give a map on the adelic curve. We are able to give a map whose entropy is the global canonical height and whose periodic points are counted asymptotically by the real division polynomial (although the archimedean component of the map is artificial). Finally, we set out a precise conjecture about the existence of elliptic dynamical systems and discuss a possible connection with mathematical physics.

description: Sentiment analysis systems have been gaining increasing popularity for extracting information regarding students' affective state. Developing such systems from scratch is a challenging task, thus, many studies employ commercial, general-purpose tools that are not domain-specific. The aim of the present work is to comparatively evaluate the performance of five well-known commercial/academic sentiment analysis tools on two educational datasets and contrast it with the performance of educational domain-specific tools, at document and sentence level. Findings suggest that: a) different tools work better for specific datasets and analysis levels, b) depending on the dataset, a general-purpose tool might be a viable solution, and c) any method, domain-specific or general-purpose one, should be evaluated before employed.

description: Die zunehmenden Anforderungen nach deterministischer Echtzeit-Kommunikation in sicherheitskritischen Systemen haben die Entwicklung von Time-Sensitive Networking (TSN) vorangetrieben. Die Anforderungen und die Umsetzung von TSN sind in den IEEE 802.1Q Standards spezifiziert. Diese Standards umfassen unter anderem die grundlegende Architektur von TSN-Netzwerken, die Spezifikationen der benötigten Kommuntikations-Schnittstellen. Das verbreitete zentralisierte TSN-Architektur-Modell umfasst neben den eigentlichen TSN-Switches auch eine zentrale Komponente, der Central Network Controller (CNC) und die Centralized User Configuration (CUC). Diese Komponenten sind gemeinsam für die Verwaltung und Konfiguration der Switches zuständig. Inzwischen nimmt die Anzahl der verfügbaren TSN-Switches zu, jedoch gibt es kaum Angebote an den Controllern. Außer der OpenCNC existieren keine wirklichen Open-Source-Alternativen einer CNC. Durch den Umfang der in den Standards spezifizierten Funktionalitäten sind auch die Implementierungen wie der OpenCNC sehr umfangreich und komplex. Da diese Komplexität die Anpassung und auch die initiale Inbetriebnahme erschwert, ist die Verwendung nur mit großem Aufwand möglich. Hier kommt diese Arbeit mit der Idee, eine einfache und kompakten CNC zu entwerfen. Ziel ist es, statt allen Funktionalitäten nur die nötigsten zu implementieren und stattdessen die Erweiterung um zusätzliche Funktionen zu ermöglichen. Dies erleichtert vor allem die Inbetriebnahme einer einfachen Konfiguration und ermöglicht die Anpassung an spezifische Anforderungen. Gerade da es viele verschiedene Scheduling-Algorithmen oder verwendbare Remote Network Management Protocols (RNMPs) gibt, ist die Flexibilität der Implementierung ein wichtiger Aspekt. Diese werden in den Standards nur konzeptionell beschrieben und sind nicht genau spezifiziert. Daher ist die Verwendung und Unterstützung mehrerer Alternativen ein wichtiger Aspekt der Erweiterbarkeit dieses Entwurfs. Der entwickelte Entwurf beschreibt die Architektur für eine zentralen CNC. Die zusätzlich verwendete CUC kommuniziert mittels dem spezifizierten User/Network Interface (UNI). Dies ermöglicht eine unabhängige Entwicklung der beiden Komponenten. Zum Abschluss der Arbeit wird eine Proof-of-Concept-Implementierung des Entwurfes in Rust bereitgestellt, die Netconf als RNMP implementiert. Diese kann mittels eines gewünschten Scheduling-Algorithmus und TSN-Switches verwendet werden. Die Funktionalität und Erweiterbarkeit der CNC werden mittels passender Testfälle und Erläuterungen zu beispielhaften Erweiterungen belegt.

description: Recent advancements in computer vision and deep learning techniques have facilitated notable progress in scene understanding, thereby assisting rescue teams in achieving precise damage assessment. In this paper, we present RescueNet, a meticulously curated high-resolution post-disaster dataset that includes detailed classification and semantic segmentation annotations. This dataset aims to facilitate comprehensive scene understanding in the aftermath of natural disasters. RescueNet comprises post-disaster images collected after Hurricane Michael, obtained using Unmanned Aerial Vehicles (UAVs) from multiple impacted regions. The uniqueness of RescueNet lies in its provision of high-resolution post-disaster imagery, accompanied by comprehensive annotations for each image. Unlike existing datasets that offer annotations limited to specific scene elements such as buildings, RescueNet provides pixel-level annotations for all classes, including buildings, roads, pools, trees, and more. Furthermore, we evaluate the utility of the dataset by implementing state-of-the-art segmentation models on RescueNet, demonstrating its value in enhancing existing methodologies for natural disaster damage assessment.

description: Stable isotope of natural gas hydrates provides useful information of their gas sources. We investigated the isotopic fractionation of gas molecules during the formation of synthetic gas hydrates composed of methane and ethane. The gas hydrate samples were experimentally prepared in a pressure cell and isotopic compositions (δ13C and δD) of both residual and hydratebound gases were measured. δD of hydrate-bound molecules of methane and ethane hydrates was several per mil lower than that of residual gas molecules in the formation processes, while there was no difference in the case of δ13C. Effect of temperature on the isotopic fractionation was also investigated and it was found that the fractionation was effective at low temperature.

description: Berry phase and Berry curvature play a key role in the development of topology in physics and do contribute to the transport properties in solid state systems. In this paper, we report the finding of novel nonzero Hall effect in topological material ZrTe5 flakes when in-plane magnetic field is parallel and perpendicular to the current. Surprisingly, both symmetric and antisymmetric components with respect to magnetic field are detected in the in-plane Hall resistivity. Further theoretical analysis suggests that the magnetotransport properties originate from the anomalous velocity induced by Berry curvature in a tilted Weyl semimetal. Our work not only enriches the Hall family but also provides new insights into the Berry phase effect in topological materials.

description: A generalized Cahn-Hilliard model in a bounded interval of the real line with no-flux boundary conditions is considered. The label "generalized" refers to the fact that we consider a concentration dependent mobility, the $p$-Laplace operator with $p>1$ and a double well potential of the form $F(u)=\frac{1}{2θ}|1-u^2|^θ$, with $θ>1$; these terms replace, respectively, the constant mobility, the linear Laplace operator and the $C^2$ potential satisfying $F"(\pm1)>0$, which are typical of the standard Cahn-Hilliard model. After investigating the associated stationary problem and highlighting the differences with the standard results, we focus the attention on the long time dynamics of solutions when $θ\geq p>1$. In the $critical$ $θ=p>1$, we prove $exponentially$ $slow$ $motion$ of profiles with a transition layer structure, thus extending the well know results of the standard model, where $θ=p=2$; conversely, in the $supercritical$ case $θ>p>1$, we prove $algebraic$ $slow$ $motion$ of layered profiles.

We study, using examples, the way advances in scientific knowledge are articulated with language knowledge, and we notably observe how French and English are alternatively used during lessons. The first case is based on a cooperative research conducted in higher education, where the aim is to study how first year bachelor students involved in a scientific programme work on the notion of uncertainty in measurements while acting in and with the English language. The second case is based on physics teaching in English in a high school, where students work on the Rutherford experience from a video in English.

description: The photonic Bose$-$Einstein condensate is a recently observed collective ground state of a coupled light-matter system. We describe this quantum state based on macroscopic quantum electrodynamics in dispersing and absorbing environments. To model the coupled photon$-$dye dynamics, we derive a master equation using a nested open quantum systems approach yielding all parameters essential to describe the condensation process. This approach allows us to describe photon condensates of arbitrary shapes because all geometry-dependent decay constants can be expressed in terms of the Green's tensor. In particular, we obtain the cavity mode absorption and emission rates of the dye molecules.

description: Virtual learning environments have been used as a tool to teach science during almost three decades. The potentialities of artificial intelligence (AI) to teach science methodology, despite of the design of various intelligent tutoring systems in the field of science, remain largely unexplored. In this article, we propose a review of the literature to put into context the rise of these AIs among the main families of technologies that have been used to foster the acquisition of inquiry skills in STEM, from computer-assisted experimentation to scaffolding tools. Some of the AIs that have been developed aim at diagnosing automatically learners’ mastery of the scientific approach, through the hypotheses they test, or the interpretations they make. The learning environment can incorporate a virtual world that allows the learner to control some variables and simulate some experiments based on the values of the variables they have set. Alternatively, the diagnosis of the learner’s inquiry skills can be made by analyzing the requests he performs on a dataset.

title: Education and its Critics: Principles and Programmes in Australian Education Policy
Creators: name: Meredyth, Denise
Publisher: name: Griffith University
Year: 1994
Subjects: subject: Australian education policy
subject: Key competencies
subject: Vocational training

description: This thesis is concerned with the relationship between the education system and its critics - with the terms in which programmes of educational reform are viewed by critical intellectuals, and with the claims and limitations of a particular mode of 'principled' critique. It explores this concern in relation to a number of recent developments in Australian education policy, describing the debates that they have engendered and identifying the political ambiguities that attend them. Three case studies are developed. The first is drawn from reactions to the recent bureaucratic reorganisation of higher education, especially those responses concentrated on the defence of the humanities. The second concerns developments in post-compulsory education, especially the construction of the new national credentialling system based on the assessment of 'Key Competencies'. The third addresses the endemic problem of educational assessment and equity. While each of these case studies is discussed in its own right, the three areas of discussion supplement one another within an overall argument concerning the relationship between the education system and a particular mode of 'principledt critique. In exploring this relationship, the thesis puts the case that we require a more historically-informed understanding of current problems in Australian education and a more pragmatic appreciation of the achievements of the existing education system. The issues raised are timely ones. Matters of educational policy have become particularly pressing over the past decade, as Australian education has undergone significant changes. In recent years, we have seen the effects of the drive towards a national education system, of the reorganisation of higher education, of the development of schemes for national credentialling and of the reconstruction of links between schooling, training and industry. These reforms have been driven by some pressing imperatives: to produce a trained and flexible workforce; to monitor levels of literacy and numeracy at a national level; and to satisfy the 'unmet demand' for increased educational places, while managing a limited educational budget.
Study of chaos in hamiltonian systems via convergent normal forms

description: We use Moser's normal forms to study chaotic motion in two-degree hamiltonian systems near a saddle point. Besides being convergent, they provide a suitable description of the cylindrical topology of the chaotic flow in that vicinity. Both aspects combined allowed a precise computation of the homoclinic interaction of stable and unstable manifolds in the full phase space, rather than just the Poincaré section. The formalism was applied to the Hénon-Heiles hamiltonian, producing strong evidence that the region of convergence of these normal forms extends over that originally established by Moser.

description: Propp conjectured that the number of lozenge tilings of a semiregular hexagon of sides $2n-1$, $2n-1$ and $2n$ which contain the central unit rhombus is precisely one third of the total number of lozenge tilings. Motivated by this, we consider the more general situation of a semiregular hexagon of sides $a$, $a$ and $b$. We prove explicit formulas for the number of lozenge tilings of these hexagons containing the central unit rhombus, and obtain Propp's conjecture as a corollary of our results.

description: With the sustainability of our future under constant threat, it is important for children to realize as soon as possible that local decisions may have global effects. This idea of the ‘local-global’ connection has been integrated in a learning environment (LE) aiming at supporting preschoolers in enhancing their conceptual understanding about nature, along with their socio-environmental awareness. The LE was designed in the context of early childhood education for sustainability (ECEfS), and implemented in a case study with 30 children. The results, that will be thoroughly discussed, suggest that the learning environment seems to work quite well regarding the socio-environmental target-idea.

description: We investigate the mechanical properties of a layered material with interlayer friction. We propose a model that contains lateral elasticity and interlayer friction to obtain the response function both in the Fourier and real spaces. By investigating how the internal deformation is laterally induced due to the applied surface displacement, we find that it is transmitted into the material with an apparent phase difference. We also obtain the effective complex modulus of the layered material and show that it exhibits an intermediate power-law behavior in the low-frequency regime. Our result can be used to estimate the internal deformation of layered materials that exist on various different scales.
Shot Noise as a probe for the pairing symmetry of Iron pnictide superconductors

description: One of the outstanding problems in Iron pnictide research is the unambiguous detection of its pairing symmetry. The most probable candidates are the two-band s$++$ and sign reversed s$\pm$ wave pairing. In this work, the Andreev conductance and shot noise are used as a probe for the pairing symmetry of Iron pnictide superconductors. Clear differences emerge in both the zero bias differential conductance and the shot noise in the tunneling limit for the two cases enabling an effective distinction between the two.

description: The work presented in this article gives an account of the origins of the difficulties of the Tunisian students of terminal of the section "Technical Sciences" in the learning of the enslavement of the technical systems. The interest is focused on the way in which students construct the concept of enslavement and regulation to be able to operationalize them on different technical systems and distinguish between those who are enslaved and those who are regulated. Interest is also focused on the origins of the difficulties encountered by students in the work of constructing functional diagrams. In this article, we present the results of a questionnaire pre-survey of 100 students in 6 high schools in the Tunisian capital. The analysis of the students' questions and answers enabled us to characterize their difficulties. This work constitutes a first part of a larger work that we envisage, in perspective, to propose a teaching-learning situation of remediation based on a didactic engineering based on numerical simulation.

Tau-functions and Dressing Transformations for Zero-Curvature Affine Integrable Equations

description: The solutions of a large class of hierarchies of zero-curvature equations that includes Toda and KdV type hierarchies are investigated. All these hierarchies are constructed from affine (twisted or untwisted) Kac-Moody algebras~$\ggg$. Their common feature is that they have some special ``vacuum solutions'' corresponding to Lax operators lying in some abelian (up to the central term) subalgebra of~$\ggg$; in some interesting cases such subalgebras are of the Heisenberg type. Using the dressing transformation method, the solutions in the orbit of those vacuum solutions are constructed in a uniform way. Then, the generalized tau-functions for those hierarchies are defined as an alternative set of variables corresponding to certain matrix elements evaluated in the integrable highest-weight representations of~$\ggg$. Such definition of tau-functions applies for any level of the representation, and it is independent of its realization (vertex operator or not). The particular important cases of generalized mKdV and KdV hierarchies as well as the abelian and non abelian affine Toda theories are discussed in detail.

description: Constant-roll warm inflation is introduced in this work. A novel approach to finding an exact solution for Friedman equations coupled to scalar field equation of motion is presented for cold inflation and is extended to warm inflation with the constant dissipative parameter $Q=\fracΓ{3H}$. The evolution of the primordial inhomogeneities of a scalar field in a thermal bath is also studied. The $1σ$ consistency between the theoretical predictions of the model and observational constraints has been proven for a range of $Q$ and $β=\frac{\ddotϕ}{3Hϕ}$ (constant rate of inflaton roll). In addition, we briefly investigate the possible enhancement of super-horizon perturbations beyond the slow-roll approximation.

description: Lévy processes on bialgebras are families of infinitely divisible representations. We classify the generators of Lévy processes on the compact forms of the quantum algebras $U_q(g)$, where $g$ is a simple Lie algebra. Then we show how the processes themselves can be reconstructed from their generators and study several classical stochastic processes that can be associated to these processes.

description: Although it is recognized that Anderson localization takes place for all states at a dimension $d$ less or equal $2$, while delocalization is expected for hopping $V(r)$ decreasing with the distance slower or as $r^{-d}$, the localization problem in the crossover regime for the dimension $d=2$ and hopping $V(r) \propto r^{-2}$ is not resolved yet. Following earlier suggestions we show that for the hopping determined by two-dimensional anisotropic dipole-dipole interactions in the presence of time-reversal symmetry there exist two distinguishable phases at weak and strong disorder. The first phase is characterized by ergodic dynamics and superdiffusive transport, while the second phase is characterized by diffusive transport and delocalized eigenstates with fractal dimension less than $2$. The transition between phases is resolved analytically using the extension of scaling theory of localization and verified numerically using an exact numerical diagonalization.

Universal statistics of non-linear energy transfer in turbulent models

description: A class of shell models for turbulent energy transfer at varying the inter-shell separation, $λ$, is investigated. Intermittent corrections in the continuous limit of infinitely close shells ($λ\rightarrow 1$) have been measured. Although the model becomes, in this limit, non-intermittent, we found universal aspects of the velocity statistics which can be interpreted in the framework of log-poisson distributions, as proposed by She and Waymire (1995, Phys. Rev. Lett. 74, 262). We suggest that non-universal aspects of intermittency can be adsorbed in the parameters describing statistics and properties of the most singular structure. On the other hand, universal aspects can be found by looking at corrections to the monofractal scaling of the most singular structure. Connections with similar results reported in other shell models investigations and in real turbulent flows are discussed.
