description: In this work we study the influence of external electric field and temperature on the chiral phase transition of Quantum Chromodynamics. We use the two-flavor Linear Sigma Model coupled with quarks (LSMq) in a thermal and electrized medium to evaluate the effective quark mass and the Schwinger pair production. To this end, we apply one-loop correction to the fermionic sector of the model and the simple tree-level approximation in the mesonic contributions. The electric fields strengthen the partial restoration of the chiral symmetry when applied with finite temperature in a crossover transition. The expected decrease of the pseudocritical temperature as a function of the electric field is observed until electric fields reach $eE\approx 13.5 m_π^2$. For stronger electric fields, the effect is the opposite, which is in a very good agreement with previous results obtained with four-point non-renormalizable models, showing that this effect is independent of renormalizability issues. We also show the thermal and electric effects on the behavior of the Schwinger pair production.

description: Die Idee des Forschungs- und Entwicklungsprojektes „Natur in der Schule“ fußt sowohl auf den langjährigen naturpädagogischen Erfahrungen der Laborschule Bielefeld und des Oberstufen-Kollegs als auch auf den intensiven Auseinandersetzungen mit dieser Thematik von Ulrich Gebhard und seiner Forschungsgruppe. Das Projekt hat das Ziel, die Bedeutung von Naturerfahrungen während der Schulzeit zu erforschen. Dabei sind sowohl die Wirkungen auf fachliche und überfachliche Lern- und Bildungsprozesse von Interesse als auch die Rolle von Natur als wichtiger Entwicklungsraum für Kinder und Jugendliche. Neben diesem zu erforschenden positiven Einfluss von Naturerfahrungen auf Lern-, Bildungs- und Entwicklungsprozesse werden ebenso die wohltuende Wirkung von Natur, der Einfluss auf soziale Beziehungen und Kompetenzen sowie die Bedeutung bzgl. der Ausbildung eines Nachhaltigkeitsbewusstseins in den Blick genommen. Den Ausgangspunkt der schulischen Naturbegegnungen stellen dabei die naturpädagogischen Prinzipien dar, welche auf theoretischen Grundlagen, pädagogischem Erfahrungswissen und empirischen Erkenntnissen basieren. Das Forschungsfeld sind die Bielefelder Versuchsschulen, in denen auch schon vor dem Vorhaben regelmäßige Naturzeiten zum Schulalltag gehörten. Derzeit werden diese hinsichtlich des Erkenntnisinteresses begleitet und beforscht. Die ersten Ergebnisse werden mit Spannung erwartet.

description: The switching dynamics of ferroelectric materials is a crucial intrinsic property which directly affects the operation and performance of ferroelectric devices. In conventional ferroelectric materials, the typical ferroelectric switching mechanism is governed by a universal process of domain wall motion. However, recent experiments indicate that Van der Waals ferroelectric CuInP2S6 possesses anomalous polarization switching dynamics under an electric field. It is important to understand the switching dynamics, but it remains theoretically unexplored in CuInP2S6 due to the lack of description of its order-disorder phase transition characteristics by density functional theory. Here, we employ a machine-learning potential trained from the first principles density functional theory dataset to conduct the large-scale atomistic simulations of temperature-driven order-disorder ferroelectric phase transition in CuInP2S6. Most importantly, it is found that the electric field-driven polarization switching in CuInP2S6 is mediated by single Cu dipole flip, rather than conventional domain wall motion mechanism. This intrinsic unconventional switching behavior can be attributed to the competition between the energy barrier of domain wall motion and single dipole flip.
Anisotropic neutrino effect on magnetar spin: constraint on inner toroidal field

description: The ultra-strong magnetic field of magnetars modifies the neutrino cross section due to the parity violation of the weak interaction and can induce asymmetric propagation of neutrinos. Such an anisotropic neutrino radiation transfers not only the linear momentum of a neutron star but also the angular momentum, if a strong toroidal field is embedded inside the stellar interior. As such, the hidden toroidal field implied by recent observations potentially affects the rotational spin evolution of new-born magnetars. We analytically solve the transport equation for neutrinos and evaluate the degree of anisotropy that causes the magnetar to spin-up or spin-down during the early neutrino cooling phase. Supposing that after the neutrino cooling phase the dominant process causing the magnetar spin-down is the canonical magnetic dipole radiation, we compare the solution with the observed present rotational periods of anomalous X-ray pulsars 1E 1841-045 and 1E 2259+586, whose poloidal (dipole) fields are $\sim 10^{15}$ G and $10^{14}$ G, respectively. Combining with the supernova remnant age associated with these magnetars, the present evaluation implies a rough constraint of global (average) toroidal field strength at $B^ϕ\lesssim 10^{15}$ G.

description: We show that, in tantalum oxide resistive memories, activation power provides a multi-level variable for information storage that can be set and read separately from the resistance. These two state variables (resistance and activation power) can be precisely controlled in two steps: (1) the possible activation power states are selected by partially reducing resistance, then (2) a subsequent partial increase in resistance specifies the resistance state and the final activation power state. We show that these states can be precisely written and read electrically, making this approach potentially amenable for ultra-high density memories. We provide a theoretical explanation for information storage and retrieval from activation power and experimentally demonstrate information storage in a third dimension related to the change in activation power with resistance.

Im ersten Abschnitt wird beschrieben, wie sich das organisationale Konzept entwickelt hat, das die Forschungs- und Entwicklungsarbeit der Laborschule in die gemeinsame Verantwortung von Versuchsschule und WE Laborschule legt. Im zweiten Abschnitt wird der derzeitige Forschungsansatz in der Laborschulforschung umrissen, bevor im dritten Abschnitt eine Analyse der Inhalte der Laborschulforschung seit 1995 vorgestellt wird. Deutlich wird die Kontinuität der Laborschulforschung in übergreifenden Themenstellungen, aber zumindest exemplarisch kann auch der Einfluss gesellschaftlicher Rahmenbedingungen auf die Forschungs- und Entwicklungs-arbeit der Laborschule nachgezeichnet werden.

description: Partant de la difficulté à se mettre au travail des élèves de l’enseignement spécialisé et à leur manque de persévérance, cette recherche a pour but d’examiner un dispositif mis en place autour d’énigmes ritualisées. La motivation est un thème central et j’ai choisi le modèle de l’engagement scolaire de Chouinard, Karsenti & Roy (2007) pour mieux comprendre les différents éléments qui la constituent et leurs liens. J’ai retenu de ce modèle quatre facteurs déterminant l’élève à s’engager dans la tâche et à persévérer malgré les obstacles : ses perceptions par rapport à sa compétence et à son contrôle, ses buts d’accomplissement, la comparaison avec ses pairs et la valeur qu’il attribue à l’activité. Cette base théorique a mené à une recherche-action avec des élèves entre douze et quatorze ans, dans une classe d’enseignement spécialisé. Chaque leçon de numération commence par la résolution d’une énigme en lien avec les notions mathématiques en jeu. A partir des narrations constituant mon journal de bord, du discours des élèves et d’un entretien critique au cours duquel chacun a cherché à résoudre une énigme, je cherche à analyser en quoi ce dispositif aide les élèves à se mettre au travail, à s’engager dans la tâche et à persévérer. Je me penche également d’une part sur le rôle de la métacognition par rapport à la motivation et d’autre part sur la question des étayages dans une perspective socioconstructiviste.

description: In this paper, we carry out a detailed analysis of the M1.6 class eruptive flare occurring in NOAA active region 13078 on 2022 August 19. The flare is associated with a fast coronal mass ejection (CME) propagating in the southwest direction with an apparent speed of $\sim$926 km s$^{-1}$. Meanwhile, a shock wave is driven by the CME at the flank. The eruption of CME generates an extreme-ultraviolet (EUV) wave expanding outward from the flare site with an apparent speed of $\geq$200 km s$^{-1}$. As the EUV wave propagates eastward, it encounters and interacts with the low-lying adjacent coronal loops (ACLs), which are composed of two loops. The compression of EUV wave results in contraction, expansion, and transverse vertical oscillations of ACLs. The commencements of contraction are sequential from western to eastern footpoints and the contraction lasts for $\sim$15 minutes. The speeds of contraction lie in the range of 13$-$40 km s$^{-1}$ in 171 Å and 8$-$54 km s$^{-1}$ in 193 Å. A long, gradual expansion follows the contraction at lower speeds. Concurrent vertical oscillations are superposed on contraction and expansion of ACLs. The oscillations last for 2$-$9 cycles and the amplitudes are $\leq$4 Mm. The periods are between 3 to 12 minutes with an average value of 6.7 minutes. The results show rich dynamics of coronal loops.

Practical Topological Cluster State Quantum Computing Requires Loss Below 1%

description: The surface code cannot be used when qubits vanish during computation; instead, a variant known as the topological cluster state is necessary. It has a gate error threshold of $0.75% and only requires nearest-neighbor interactions on a 2D array of qubits. Previous work on loss tolerance using this code only considered qubits vanishing during measurement. We begin by also including qubit loss during two-qubit gates and initialization, and then additionally consider interaction errors that occur when neighbors attempt to entangle with a qubit that isn't there. In doing so, we show that even our best case scenario requires a loss rate below 1% in order to avoid considerable space-time overhead.

description: We explore the structure of the ground state of $^{20}$Ne by investigating various density profiles. Four candidates for the ground state configurations, (a) $j$-$j$ coupling and (b) SU(3) shell model and (c) $5α$ and (d) $^{16}{\rm O}+α$ cluster model configurations are generated by utilizing the antisymmetrized quasicluster model. A high-energy reaction theory, the Glauber model, relates these one-body density distributions and reaction observables. The angular distributions of the elastic scattering cross sections clearly distinguish these configurations and tell which is the most plausible one: The ground state of $^{20}$Ne favors a 16+4 nucleon bi-cluster structure. A comprehensive investigation of other electric observables also supports this conclusion.

description: Ce travail s'intéresse à la possibilité d'enseigner la programmation informatique au secondaire 1. A cet effet, une séquence d'enseignement de six périodes de 45 minutes a été conçue dans le but d'être dispensée à des élèves de 13 à 15 ans n'ayant aucune connaissance préalable de programmation informatique. Cette séquence d'enseignement a pour principale ambition d'introduire les concepts de commande, de variable, de boucle et de structure de contrôle. Cette séquence est basée sur un langage visuel de programmation : le langage retenu est Scratch (Lifelong Kindergarten, 2016). Une fois créée, la séquence d'enseignement a été dispensée à une classe multi-âges de huit élèves. Le déroulement de la séquence, ainsi que les travaux réalisés par les élèves, ont été analysés en détail. Globalement le déroulement de la séquence a été un succès, et les attentes de l'enseignant ont largement été satisfaites. Bien que les élèves n'avaient jamais entendu parler de programmation informatique auparavant, ils ont réalisé avec succès les tâches proposées et se sont montré très intéressés par la programmation informatique. L'analyse du déroulement de la séquence et du travail fourni par les élèves n'a pas permis de mettre en évidence de diffculté notable au niveau de l'apprentissage de la programmation informatique : les différents concepts introduits ont été assimilés par les élèves sans diffculté majeure. En revanche, la conception du langage de programmation Scratch et de l'environnement de développement de Scratch a engendré de nombreuses diffcultés. Ces diffcultés sont présentées dans ce travail et des propositions d'amélioration sont proposées.

description: Classical T Tauri stars are low-mass pre-main sequence stars with an active circumstellar environment. In this work we present the identification and study of 260 Classical T Tauri stars using LAMOST Data Release 6, among which 104 stars are newly identified. We distinguish Classical T Tauri stars from Giants and main-sequence dwarfs based on the log g values and the presence of H (alpha) emission line and infrared excess that arises from the circumstellar accretion disk. We estimated the mass and age of 210 stars using the Gaia color-magnitude diagram. The age is from 0.1 to 20 Myr, where 90% of the stars have age below 10 Myr and the mass ranges between 0.11 to 1.9 M(solar). From the measured H(alpha) equivalent widths, we homogeneously estimated the mass accretion rates for 172 stars, with most values ranging from 10^-7 to 10^-10 M(solar) yr^-1. The mass accretion rates are found to follow a power law distribution with the mass of the star, having a relation of the form Macc proportional to M(star)^1.43 +/- 0.26, in agreement with previous studies.

description: Northamptonshire Archaeology, 37, 69-87
description: Excavation of late medieval and post-medieval buildings in 1995 near Warmington Mill, Eaglethorpe, Warmington, close to the River Nene, produced the unexpected bonus of a crouched Beaker inhumation burial of the Early Bronze Age. An adult male, 35-45 years of age, lay in a flat grave, with no encircling barrow ditch. He was accompanied by a Beaker, two V-perforated jet buttons, a broken flint dagger, a flint fabricator and a superb barbed-and-tanged arrowhead. The burial has been radiocarbon dated to the 20th century BC. Beaker graves with no encircling ditch and perhaps never covered by substantial mounds, are known in small numbers across England, but finding them is necessarily a matter of chance, as at Warmington, so they are likely to be underrepresented in the archaeological record. However, only 3.5km to the south of Warmington, a further two flat graves containing crouched Beaker burials had also been found by chance during excavations at Ashton Roman town in the early 1980s. These burials are also briefly described, and one has also been radiocarbon dated to the 20th century BC.�������������������������

description: An archaeological evaluation was carried out by Northamptonshire Archaeology on 180 hectares of open farmland to the north-east, east and south-east of Wootton, Northampton. Areas of archaeological remains had been identified from aerial photographs and geophysical survey, and these and the intervening areas were examined and characterised through the excavation of 306 trial trenches. This report focuses on the features of certain or likely Bronze Age date. At the northern end of the site, on the Hunsbury ridge, there are two or possibly three ring ditches, probably the remains of Bronze Age round barrows, one of which had been previously investigated. There was also a dispersed pattern of field or enclosure ditches of possible Iron Age date. On the lower slopes to the north of Wootton Brook there was a single pit, radiocarbon dated to the Early Bronze Age, containing a deposit of dark charcoal-rich soil, with a small amount of cremated bone, at least partly cattle bone, three flint arrowheads and a scraper. This pit joins the growing corpus of Neolithic and Bronze Age pits in the region located in recent years as chance finds during the investigation of extensive development sites. In the same area there was also an Iron Age ring ditch and several late Iron Age ditches. At the southern end of the site, on a low prominence south of Wootton Brook, a middle/late Iron Age settlement comprised a sub-rectangular enclosure as well as subsidiary enclosures and pits. An isolated ring ditch in this area may be either a Bronze Age ring ditch or part of the Iron Age complex.�����������

description: It has recently been argued that individual 1D quasicrystals can be ascribed 2D topological quantum numbers and a corresponding set of topologically protected edge modes. Here, we demonstrate the equivalence of such 1D quasicrystals to a mean-field treatment of incommensurate charge order in 1D materials. Using the fractal nature of the spectrum of commensurate charge-ordered states we consider incommensurate order as a limiting case of commensurate orders. We show that their topological properties arise from a 2D parameter space spanned by both phase and wave vector, bringing the observation of 2D edge modes in line with the standard classification of topological order.The equivalence also provides a set of real-world quasiperiodic materials which can be readily experimentally examined. We propose an experimental test of both the quasicrystalline and topological character of these systems in the form of a quantized adiabatic particle transport upon dragging the charge-ordered state.

We find that: (i) levels of news avoidance grew sharply in April and May at the start of lockdown and have broadly remained at high levels since then, (ii) even as the proportion that say COVID-19 is the single most important issue facing the UK today fell from 72% at the end of April, to 51% in mid-July. (iii) Most of those that avoid news about COVID-19 say it is because "it has a bad effect on my mood”, and most COVID-19 news avoiders say that they avoid news on television.

description: Dans le cadre de ma pratique d’enseignante spécialisée dans les classes primaires du degré 3H de l’école valaisanne, j’ai pu observer des élèves qui avaient des difficultés dans l’apprentissage de la lecture en début d’année scolaire. Je me suis donc intéressée aux moyens d’enseignement de la lecture qui étaient mis à disposition des enseignants valaisans sur le catalogue de la centrale cantonale des moyens d’enseignement (CECAME). Ces dernières années, les deux courants principaux sur l’enseignement-apprentissage de la lecture viennent des recherches en sciences de l’éducation et des recherches en sciences cognitives. J’ai donc pris la décision d’orienter mon cadre conceptuel du côté des recherches en sciences cognitives car il était important pour moi d’en savoir un peu plus sur la dynamique cérébrale des élèves qui apprennent à lire. Suite à ce cadre conceptuel, j’ai élaboré une grille d’analyse de contenu en me basant sur les grands principes fondamentaux de l’enseignement de la lecture tirés du livre « Apprendre à lire. Des sciences cognitives à la salle de classe » (Dehaene, 2011). Cette grille se compose de cinq catégories et de 27 indicateurs ; un d’entre eux est tiré du livre « Lecture et dyslexie. Approche cognitive » (Sprenger-Charolles & Colé, 2013). Six moyens d’enseignement de la lecture mis à disposition des élèves valaisans de 3H ont été passés au crible de cette grille. L’analyse des résultats a démontré que les deux moyens qui étaient essentiellement tournés vers un enseignement systématique des correspondances graphophonémiques obtenaient le plus grand nombre d’indicateurs positifs en lien avec les recherches en sciences cognitives.

description: This paper explores steganography from its earliest instances, problems of steganography techniques, analyse image files formats for steganographic content, potential future application, security and payload or image perceptibility enhancement techniques. In addition, a demonstration of brute force attack was implemented against the stego image, in order to test the robustness of the proposed system. It was also observed that .png image are considered to be more suitable for steganography. i.e Lossless image with a high degree of verbosity or redundancy. In this scenario, redundancy is termed as the amount of bits streams or data can be skipped without affecting the actual significance and purpose of information.
On mean elements in artificial satellite theory

description: The merits of a perturbation theory based on a mean to osculating transformation that is pure periodic in the fast angle are investigated. The exact separation of the purely short-period effects of the perturbed Keplerian dynamics from the long-period mean frequencies is achieved by a non-canonical transformation, which, therefore, cannot be computed by Hamiltonian methods. For this case, the evolution of the mean elements strictly adheres to the average behavior of the osculating orbit. However, due to the inescapable truncation of perturbation solutions, the fact that this theory confines the long-period variations of the semimajor axis into the mean variation equations, how tiny they may be, can have adverse effects in the accuracy of long-term semi-analytic propagations based on it

An Archaeological Survey of the Hunsbury Hillfort Defences
Creators: name: Jackson, Dennis A

description: Northamptonshire Archaeology, 37, 109-134
description: This project sought to assess the condition of the earthworks at Hunsbury, establish the extent of archaeological survival within the ramparts and examined a previously recorded external ditch. Three geophysical surveys were commissioned which were followed by small scale trial excavations. These demonstrated that the 19th-century quarrying within the interior in the 19th century had left a small but significant area intact which was larger than previously imagined. It also showed that the hillfort had a vitrified rampart, a comparative rarity in England and confirmed the existence of a substantial but incomplete and undated outer ditch.
The Role of the Magnetorotational Instability in the Sun

description: We calculate growth rates for nonaxisymmetric instabilities including the magnetorotational instability (MRI) throughout the Sun. We first derive a dispersion relation for nonaxisymmetric instability including the effects of shear, convective buoyancy, and three diffusivities (thermal conductivity, resistivity, and viscosity). We then use a solar model evolved with the stellar evolution code MESA and angular velocity profiles determined by Global Oscillations Network Group (GONG) helioseismology to determine the unstable modes present at each location in the Sun and the associated growth rates. The overall instability has unstable modes throughout the convection zone and also slightly below it at middle and high latitudes. It contains three classes of modes: large-scale hydrodynamic convective modes, large-scale hydrodynamic shear modes, and small-scale magnetohydrodynamic (MHD) shear modes, which may be properly called MRI modes. While large-scale convective modes are the most rapidly growing modes in most of the convective zone, MRI modes are important in both stably stratified and convectively unstable locations near the tachocline at colatitudes theta less than 53 degrees. Nonaxisymmetric MRI modes grow faster than the corresponding axisymmetric modes; for some poloidal magnetic fields, the nonaxisymmetric MRI growth rates are similar to the angular rotation frequency Omega, while axisymmetric modes are stabilized. We briefly discuss the saturation of the field produced by MRI modes, finding that the implied field at the base of the convective zone in the Sun is comparable to that derived based on dynamos active in the tachocline and that the saturation of field resulting from the MRI may be of importance even in the upper convection zone.

A new interpretation of the Sculpted Tympanum of All Saints, Pitsford
Creators: name: Curtis Webb, Mary
Publisher: name: Archaeology Data Service
Year: 2020

description: Northamptonshire Archaeology, 37, 135-143
description: The carving on the tympanum of All Saints church, Pitsford is one of a group of rare 12th-century English sculptures depicting Christ's Redemption of mankind. The scene is Christ's Descent into Hades to destroy Death, here personified by Behemoth, the twin figure of Leviathan. The main literary source of these carvings is the Ransom Theory as expounded by Pope Gregory the Great in his lengthy commentary on the Book of Job, the Moralia in Job completed shortly before 597. At the end of the 12th century the Ransom Theory was abandoned in favour of Anselm's exposition of the Doctrine of the Atonement. Consequently, carvings depicting the Ransom theory, such as the Pitsford tympanum, vanished for ever from the repertoire of ecclesiastical sculpture, and the scenes and characters depicted are now either a source of mystery or are reinterpreted to fit later doctrines. It is to be hoped that the unique historical importance of the whole surviving corpus of 12th-century English sculpture will become more widely recognised and that this heritage will be properly preserved for posterity.��

description: In this RISJ Factsheet we examine how people think about the coronavirus pandemic in the UK and how different institutions in the UK have responded to it. This is the seventh in a series of ten factsheets based on an ongoing online panel survey of a representative sample of the UK population, fielded from 2 July to 8 July 2020. We find that: (i) a majority (57%) of the public say they think the UK government’s response to the coronavirus pandemic has been worse than most other developed countries (up from 46% in late April), (ii) almost half (44%) feel that the government response is too focused on protecting the economy (up from 19%), but (iii) perception of news media coverage of the government is largely unchanged, with one third (33%) saying the coverage has not been critical enough, 26% too critical, and 28% saying coverage has been fair.

description: In this RISJ Factsheet we examine people’s use of social media as a source of news and information during the coronavirus pandemic in the UK. This is the sixth in a series of ten factsheets based on an ongoing online panel survey of a representative sample of the UK population, fielded from 18 June to 24 June 2020. We find that: (i) the use of social media in general has remained consistent during the coronavirus pandemic, but the use of many social networks specifically for news and information about COVID-19 fell from April to June, (ii) with Facebook and Twitter (both used by 12%) the social networks most widely-used for news and information about COVID-19, and with fewer people saying they use YouTube (5%), WhatsApp (3%) and Instagram (4%). However, (iii) around 10% say that they trust news and information about COVID-19 on social media, video sites and messaging apps.
Observation of collider muon neutrinos with the SND@LHC experiment

description: We report the direct observation of muon neutrino interactions with the SND@LHC detector at the Large Hadron Collider. A data set of proton-proton collisions at $\sqrt{s} = 13.6\,$TeV collected by SND@LHC in 2022 is used, corresponding to an integrated luminosity of 36.8$\,\rm{fb}^{-1}$. The search is based on information from the active electronic components of the SND@LHC detector, which covers the pseudo-rapidity region of $7.2 < η< 8.4$, inaccessible to the other experiments at the collider. Muon neutrino candidates are identified through their charged-current interaction topology, with a track propagating through the entire length of the muon detector. After selection cuts, 8 $ν_μ$ interaction candidate events remain with an estimated background of 0.076 events, yielding a significance of seven standard deviations for the observed $ν_μ$ signal.
