description: The velocity “kink” kinematic signature has gained standing as a promising method for discovering embedded planets. The gravitational influence of a planetary perturber is predicted to drive spiral wakes that disturb the surrounding gas velocity, generating distinct “kinks” along the spiral arms observable in velocity channel maps of gas emission. To date, a dozen velocity kink detections have been reported in ALMA observations of disks, and most have pinpointed the candidate planets within gaps in the ALMA dust continuum.
 The understanding that velocity kinks are due to spiral arms enables us to make a robust, testable prediction: Every instance of velocity kinks should be concurrent with spiral density waves. In this talk, I describe the results from our search for the spirals driven by the kink planets in the ALMA dust continuum. Our work provides an independent method to verify the existence of these planet candidates, and more importantly, tests the validity of velocity kinks as a reliable signpost of planets in disks.

description: The two-dimensional electron system formed at the interface between the insulating oxides LaAlO3 and SrTiO3 exhibits ferromagnetism, superconductivity, and a wide range of unique magnetotransport properties. A key challenge is to find a unified microscopic mechanism that underlies these emergent phenomena. Here we show that a universal Lifshitz transition between d-orbitals lies at the core of the observed transport phenomena in this system. Our measurements find a critical electronic density at which the transport switches from single to multiple carriers. This density has a universal value, independent of the LaAlO3 thickness and electron mobility. The characteristics of the transition, its universality, and its compatibility with spectroscopic measurements establish it as a transition between d-orbitals of different symmetries. A simple band model, allowing for spin-orbit coupling at the atomic level, connects the observed universal transition to a range of reported magnetotransport properties. Interestingly, we also find that the maximum of the superconducting transition temperature occurs at the same critical transition, indicating a possible connection between the two phenomena. Our observations demonstrate that orbital degeneracies play an important role in the fascinating behavior observed so far in these oxides.

Competitive Privacy in the Smart Grid: An Information-theoretic Approach

description: Advances in sensing and communication capabilities as well as power industry deregulation are driving the need for distributed state estimation in the smart grid at the level of the regional transmission organizations (RTOs). This leads to a new competitive privacy problem amongst the RTOs since there is a tension between sharing data to ensure network reliability (utility/benefit to all RTOs) and withholding data for profitability and privacy reasons. The resulting tradeoff between utility, quantified via fidelity of its state estimate at each RTO, and privacy, quantified via the leakage of the state of one RTO at other RTOs, is captured precisely using a lossy source coding problem formulation for a two RTO network. For a two-RTO model, it is shown that the set of all feasible utility-privacy pairs can be achieved via a single round of communication when each RTO communicates taking into account the correlation between the measured data at both RTOs. The lossy source coding problem and solution developed here is also of independent interest.

description: We present a detailed analysis of the global and fine structure of four middle-mass disc galaxies obtained from simulations in a $Λ$CDM scenario. These objects have photometric D/T ratios in good agreement with those observed for late-type spirals, as well as kinematic properties in agreement with the observational Tully-Fisher relation. We identify the different dynamical components at z=0 on the basis of both orbital parameters and the binding energy of stars in the galaxy. In this way, we recognize a slowly rotating centrally concentrated spheroid, and two disc components supported by rotation: a thin disc with stars in nearly circular orbits, and a thick disc with orbital parameters transitional between the thin disc and the spheroid. The spheroidal component is composed mainly by old, metal-poor and α-enhanced stars. The distribution of metals in this component shows, however, a clear bimodality with a low-metallicity peak, which could be related to a classical bulge, and a high-metallicity peak, which could be related to a pseudo-bulge. The thin disc appears in our simulations as the youngest and most metal-rich component. The radial distribution of ages and colours in this component are U-shaped: the new stars are forming in the inner regions, and then migrate through secular processes. Finally, we also find a thick disc containing about 16% of the total stellar mass and with properties that are intermediate between those of the thin disc and the spheroid. Its low-metallicity stars are α-enhanced when compared to thin disc stars of the same metallicity. The structural parameters (e.g., the scale height) of the simulated thick discs suggest that such a component could result from the combination of different thickening mechanisms that include merger-driven processes, but also long-lived internal perturbations of the thin disc.

description: More than 4000 exoplanets have been discovered so far, and they are part of planetary systems that are very different from each other and from our Solar system. To investigate this (physical or chemical) diversity it is crucial to characterize the initial stage of their formation, represented by Solar-type protostars. Indeed, there are evidence that the planet formation could already start at these stages. The gaseous chemical content of these objects, that represents the one available for future forming planets, depends on the composition of the dust grain mantles formed before the collapse starts. Directly retrieving the ice mantle composition is challenging, but it can be done indirectly by observing the ice major species once they are release into the gas-phase during the warm protostellar stage. In this contribution I will show the results from our VLA high angular resolution (~300 au) observations of NH3 and CH3OH. Comparing the observed NH3/CH3OH ratio with up-to-date astrochemical models, we could derive the chemical and dynamical history of the NGC 1333 IRAS 4 protostars. Indeed, the three protostars share the same history, characterized by a fast collapse triggered by a brutal external event, that set the observed chemistry. These results will highlight the crucial role of low frequency observations (VLA, ALMA Band 1, and future SKA, ngVLA) in retrieving the protostellar ice mantle history and in giving insight on the dynamics of their birth environment.

description: Sozialwissenschaftliche Inhalte abseits der klassischen staatsbürgerlichen Erziehung, wurden in Österreich erstmals in der pädagogischen Reformära der 1920er Jahre diskutiert und in Schulversuchen erprobt. Mit dem Schulorganisationsgesetz (SCHOG) 1962, das das Österreichische Schulwesen nach dem 2. Weltkrieg neu ordnete, wurden in den allgemeinbildenden Schulen (Gymnasien und Hauptschulen) wirtschaftliche und politisch bildende Lehrinhalte und Ziele in die Unterrichtsgegenstände (Fächer) "Geographie und Wirtschaftskunde" bzw. "Geschichte und Sozialkunde" integriert. Diese zunächst eher formalen, additiven Verbindungen wurden 1978 durch das "Unterrichtsprinzip Politische Bildung" ergänzt. Die Lehrplanreformen Mitte/Ende der achtziger Jahre sowie 2002 versuchten eine stärkere Integration. In den berufsbildenden Schulen bestehen eigene Unterrichtsgegenstände für die genannten Bereiche.

description: Das Verhältnis von Didaktik der Politischen Bildung und Allgemeiner Pädagogik ist immer stärker von der weitergehenden Ausdifferenzierung der pädagogischen Disziplinen gezeichnet. Dies führte zu einer Entfernung der Disziplinen, die bis hin zur Kommunikationslosigkeit reicht. Anliegen dieses Beitrages ist es, anhand eines bestimmten Themas, der Lehrplananalyse, dieser Sprachlosigkeit ein Gesprächsangebot entgegenzusetzen. In einer von der DFG geförderten Forschergruppe zur Untersuchung der Übergangsphasen zu Beginn der SBZ/DDR und nach der Gründung der neuen Länder entwickelte das Projekt "Bildungstheorie und Unterricht" neun Kriterien zur Unterscheidung von affirmativen und reflektierenden Lernzielnormierungen. Diese Kriterien werden vorgestellt und auf ihre mögliche Bedeutung für die Politische Bildung hin ausgelegt und erläutert. Dabei greift der Autor u.a. auf Erfahrungen zurück, die er mit der Analyse der thüringischen Lehrplanentwicklung im Fach "Sozialkunde" gemacht hat. Zugleich sollen Anschlussmöglichkeiten an Überlegungen der Politikdidaktik zumindest kursorisch aufgezeigt werden. Als Voraussetzung dafür wird der verwendete Transformationsbegriff vorgestellt. Über das Aufzeigen von Relevanzbildungskriterien und erziehungstheoretischen Kriterien für die Lehrplananalyse soll das Gespräch zwischen den Disziplinen neu belebt werden.

description: This paper demonstrates the quantization of a spatial Cournot duopoly model with product choice, a two stage game focusing on non-cooperation in locations and quantities. With quantization, the players can access a continuous set of strategies, using continuous variable quantum mechanical approach. The presence of quantum entanglement in the initial state identifies a quantity equilibrium for every location pair choice with any transport cost. Also higher profit is obtained by the firms at Nash equilibrium. Adoption of quantum strategies rewards us by the existence of a larger quantum strategic space at equilibrium.

title: A new exact algorithm to solve the Multiple-Choice Multidimensional Knapsack Problem: The Utility Sorted Branch and Bound Algorithm
Creators: name: Kreß, Antonio
name: Kiel, Florian
name: Metternich, Joachim
Publisher: name: UNSPECIFIED
Year: 2021

description: This paper offers an exact algorithm for one of the most complex members of the Knapsack Problem family: The Multiple-choice Multidimensional Knapsack Problem (MMKP). Based on a literature survey, only a few exact algorithms exist for the MMKP. The proposed algorithm excludes ranges of the possible solution space through systematic variations of ranked elements by utility sorting. Based on logical rules, successor nodes of a feasible node cannot include the optimal solution. Besides a literature survey as well as a detailed description of the algorithm and the test design, the results of a computational study on 11,160 instances are presented. The efficiency of the algorithm depends on the number of classes, elements per class, number of restrictions, and the degree of restrictiveness. Using the distribution of a search quotient shows the relative number of examined solutions being investigated. Testing against a brute-force algorithm reveals that all problem instances could be solved exactly while reducing the number of node enumerations. Furthermore, the structure of the algorithm allows its usage on other members of the knapsack problem family.

description: We study a modification of the Plebanski action, which generically corresponds to a bi-metric theory of gravity, and identify a subclass which is equivalent to the Bergmann-Wagoner-Nordtvedt class of scalar-tensor theories. In this manner, scalar-tensor theories are displayed as constrained BF theories. We find that in this subclass, there is no need to impose reality of the Urbantke metrics, as also the theory with real bivectors is a scalar-tensor theory with a real Lorentzian metric. Furthermore, while under the former reality conditions instabilities can arise from a wrong sign of the scalar mode kinetic term, we show that such problems do not appear if the bivectors are required to be real. Finally, we discuss how matter can be coupled to these theories. The phenomenology of scalar field dark matter arises naturally within this framework.

description: Quantum walks have been shown to have impressive transport properties compared to classical random walks. However, imperfections in the quantum walk algorithm can destroy any quantum mechanical speed-up due to Anderson localization. We numerically study the effect of static disorder on a quantum walk on the glued trees graph. For small disorder, we find that the dominant effect is a type of quantum decay, and not quantum localization. For intermediate disorder, there is a crossover to diffusive transport, while a localization transition is observed at large disorder, in agreement with Anderson localization on the Cayley tree.

description: Since ten or fifteen years ago, civic education is coming back to the foreground of the news. It is now an obligatory school subject in primary and lower secondary school, the college, namely nine years of a schooling which it is as a rule the same for all pupils. The author introduces programmes from primary school and from the college. However, between official programmes and what is effectively taught, differences are often very large. What some primary school's teachers say about what they teach and about college's pupils provides another point of view on civic education. A short evocation of the history of civic education in French school puts in prospect actual choices and specific problems of this school subject, in particularly its difficult stabilisation. The article closes with the presentation of some tensions and contradictions which are necessary to take into account to think and to implement civic education.

description: We develop a non-perturbative "gauge Mean Field Theory" (gMFT) method to study a general effective spin-1/2 model for magnetism in rare earth pyrochlores. gMFT is based on a novel exact slave-particle formulation, and matches both the perturbative regime near the classical spin ice limit and the semiclassical approximation far from it. We show that the full phase diagram contains two exotic phases: a quantum spin liquid and a coulombic ferromagnet, both of which support deconfined spinon excitations and emergent quantum electrodynamics. Phenomenological properties of these phases are discussed.

description: We made a detailed observational analysis of a well known hot molecular core lying in the high-mass star-forming region G31.41+0.31. This core is believed to contain deeply embedded massive stars and presents a velocity gradient that has been interpreted either as rotation or as expansion, depending on the authors. Our aim was to shed light on this question and possibly prepare the ground for higher resolution ALMA observations which could directly detect circumstellar disks around the embedded massive stars. Observations at sub-arcsecond resolution were performed with the Submillimeter Array in methyl cyanide, a typical hot molecular core tracer, and 12CO and 13CO, well known outflow tracers. We also obtained sensitive continuum maps at 1.3 mm. Our findings confirm the existence of a sharp velocity gradient across the core, but cannot confirm the existence of a bipolar outflow perpendicular to it. The improved angular resolution and sampling of the uv plane allow us to attain higher quality channel maps of the CH3CN lines with respect to previous studies and thus significantly improve our knowledge of the structure and kinematics of the hot molecular core. While no conclusive argument can rule out any of the two interpretations (rotation or expansion) proposed to explain the velocity gradient observed in the core, in our opinion the observational evidence collected so far indicates the rotating toroid as the most likely scenario. The outflow hypothesis appears less plausible, because the dynamical time scale is too short compared to that needed to form species such as CH3CN, and the mass loss and momentum rates estimated from our measurements appear too high.

Civic, Legal and Social Education in French Secondary School: Questions About a New Subject
Creators: name: Tutiaux-Guillon, Nicole

Year: 2003
Subjects: -

description: In summer 1999, a new compulsory subject was introduced in French upper secondary school: civic, legal and social education (éducation civique, juridique et sociale or ECJS). This teaching has been introduced as an answer to problems resulting from social and cultural changes in secondary education, from growing indifference to politics and from debates about citizenship. The curriculum in ECJS, through contents based on concepts and social and political controversies, and through pedagogy based on debates, upsets traditional secondary teaching. What is taught and what is learnt differ a lot form one classroom to another. The thesis presented in this paper asserts that this subject shows such an heterogeneity not only because it is new, but also because the three actors in the project, the institution, the teachers and the students, refer ECJS to legitimacies and to contents that do not coincide. The institution refers largely to politics and citizenship, the teachers to school difficulties and school knowledge, the students to their personal experience and common sense. This interpretation calls for discussion.

description: It is rather difficult to describe economic education in Germany: Due to German federalism the sixteen German Länder are independent in terms of educational policy. Thus the German educational system differs slightly from Land to Land, even more heterogenous is the situation of economic education. With regard to this it is impossible to give a detailed picture of the whole, but it is useless to present the situation in only one land. This report tries to do the impossible by giving a rough overview of the situation of economic education in Germany at school as well as at university. Above all it is concerned with outlining the gap between claim and reality of economic education. A summary about the main topics of the didactic discussion can reflect contents and methods, which influence the syllabus construction.

description: We present a detailed study of the ground-state magnetic structure of ultrathin Fe films on the surface of fcc Ir(001). We use the spin-cluster expansion technique in combination with the relativistic disordered local moment scheme to obtain parameters of spin models and then determine the favored magnetic structure of the system by means of a mean field approach and atomistic spin dynamics simulations. For the case of a single monolayer of Fe we find that layer relaxations very strongly influence the ground-state spin configurations, whereas Dzyaloshinskii-Moriya (DM) interactions and biquadratic couplings also have remarkable effects. To characterize the latter effect we introduce and analyze spin collinearity maps of the system. While for two monolayers of Fe we find a single-q spin spiral as ground state due to DM interactions, for the case of four monolayers the system shows a noncollinear spin structure with nonzero net magnetization. These findings are consistent with experimental measurements indicating ferromagnetic order in films of four monolayers and thicker.

description: Fermionic linear optics is a limited form of quantum computation which is known to be efficiently simulable on a classical computer. We revisit and extend this result by enlarging the set of available computational gates: in addition to unitaries and measurements, we allow dissipative evolution governed by a Markovian master equation with linear Lindblad operators. We show that this more general form of fermionic computation is also simulable efficiently by classical means. Given a system of $N$ fermionic modes, our algorithm simulates any such gate in time $O(N^3)$ while a single-mode measurement is simulated in time $O(N^2)$. The steady state of the Lindblad equation can be computed in time $O(N^3)$.

description: With recent advances in graphical user interfaces, more and more tasks on computers have become easier to perform. Out of the belief that creating computer programs can also be one of them, visual programming languages (VPLs) have emerged. The goal of VPLs is to shift a part of work from the programmer to the IDE so that the programmer can focus more on algorithm logic than the syntax of the implementation programming language. In this article, the methods required to build a VPL are presented, with an emphasis on a novel method of code generation in a WHILE language. Also, the methods for achieving basic principles of VPLs will be shown - suitable visual presentation of information and guiding the programmer in the right direction using constraints. These methods are demonstrated on an example of vIDE, a VPL based on the Eclipse integrated development environment (IDE). The design of vIDE with respect to the Eclipse Graphical Modeling Framework (GMF) is described. The concept of a flowchart graphical notation is examined in contrast with the algorithm model it maps to. Finally, the disambiguity of the model representation of an algorithm is discussed and the methods for transforming it to an actual implementation in a programming language.

description: Proton decay is a generic prediction of GUT models and is therefore an important channel to detect the existence of unification or to set limits on GUT models. Current bounds on the proton lifetime are around 10^33 years, which sets stringent limits on the GUT scale. These limits are obtained under `reasonable' assumptions about the size of the hadronic matrix elements. In this paper we present a non-perturbative calculation of the hadronic matrix elements within the chiral bag model of the proton. We argue that there is an exponential suppression of the matrix elements, due to non-perturbative QCD, that stifles proton decay by orders of magnitude -- potentially O(10^-10). This suppression is present for small quark masses and is due to the chiral symmetry breaking of QCD. Such a suppression has clear implications for GUT models and could resuscitate several scenarios.

description: The following essay gives an overview of the development of civic education at German schools in the 20th century. This is based on the study of German contributions to the international comparative project "Civic Education" within the scheme of the International Association for Evaluation of Educational achievement (IEA), which were published internationally and by the German project group. Essential empirical findings are taken into account to describe civic education in Germany in an international comparison. This article helps for a better understanding of civic education in Germany under both a historical and comparative perspective.

description: In our search for life beyond Earth, nobody knows whether we will find a sign of biology or technology first, and in such a setting of high uncertainty, it is most reasonable to assume that both search strategies have equal chances of success (see Wright et al. 2022). Yet, humans have dedicated and are currently dedicating many more resources (people, instruments, funding) to search for biosignatures than to search for technosignatures. Why? This poster explores some of the key historical, cultural and psychological reasons underlying this discrepancy.
 Historically, we review how the effort has been ridiculed (e.g. by Simpson, Tipler, Mayr or the US Congress, see Garber 1999).
 Regarding popular culture, we show how science fiction and ufology tend to discredit the seriousness of the effort.
 On the psychological side, we hypothesize that researchers conducting bio- or techno- signature searches have different orientations, namely a risk-averse and past-oriented psychology, versus a risk-prone and future-oriented one.
 We also highlight the highly different psychological impact of discovering a bio- versus techno- signature (Vidal 2015). We argue that both biosignature and technosignature searches deserve equal attention and opportunity. By understanding the origin of this imbalance in resource allocation, we call for giving equal chances to bio- and techno- signatures searches and thereby aim to improve the overall chance of finding ET life.

Twin and Mirror Symmetries from Presymmetry

Year: 2011
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We argue that presymmetry, a hidden predynamical electroweak quark-lepton symmetry that explains the fractional charges and triplication of families, must be extended beyond the Standard Model as to have a residual presymmetry that embraces partner particles and includes the strong sector, so accounting for the twin or mirror partners proposed to alleviate the naturalness problem of the weak scale. It leads to the full duplication of fermions and gauge bosons of the Standard Model independently of the ultraviolet completion of the theory, even if the Higgs particle is discarded by experiment, which adds robustness to twin and mirror symmetries. The established connection is so strongly motivated that the search for twin or mirror matter becomes the possible test of presymmetry. If the physics beyond the Standard Model repairs its left-right asymmetry, mirror symmetry should be the one realized in nature.

description: The pressure-dependent relation between Eu valence and lattice structure in model compound EuO is studied with synchrotron-based x-ray spectroscopic and diffraction techniques. Contrary to expectation, a 7% volume collapse at $\approx$ 45 GPa is accompanied by a reentrant Eu valence transition into a $\emph{lower}$ valence state. In addition to highlighting the need for probing both structure and electronic states directly when valence information is sought in mixed-valent systems, the results also show that widely used bond-valence methods fail to quantitatively describe the complex electronic valence behavior of EuO under pressure.

Ancient India's Use of Seals: A Descriptive Study
Creators: name: Dr. Satyamangal Rege
Publisher: name: Institute for Interdisciplinary and Venture Publication
Year: 2025

description: Particularly during the Indus Valley Civilization (c. 2600–1900 BCE) and later historical periods, the study of seals in ancient India offers vital insights into the sociopolitical, economic, and cultural fabric of early civilizations. This study summarizes the various applications of seals in ancient India by combining scholarly interpretations, archaeological discoveries, and epigraphic data to demonstrate their complex functions. Seals, which frequently bore elaborate inscriptions and imagery denoting ownership, trade links, or official roles, functioned as marks of identification, authority, and commerce. Steatite carvings with mysterious lettering and animal patterns on Indus seals suggest a highly developed trading network that extended throughout Mesopotamia and beyond. Later seals, such as those from the Mauryan and Gupta eras, illustrate how government, religious symbolism, and bureaucratic uniformity evolved over time. To shed light on regional influences and technological advancements, this study also examines the materials, craftsmanship, and stylistic variations of these seals. Through a critical engagement with primary sources and archaeological data, this study clarifies the significance of seals in understanding ancient Indian urban design, economic organization, and political administration. Additionally, it explores how the usage of seals has changed and remained consistent over time, establishing links between historical and pre-modern customs. The study emphasizes the necessity of further multidisciplinary research to unravel unresolved mysteries, particularly the undeciphered Indus script, which remains a major enigma in South Asian history. By highlighting the significance of seals as cultural artifacts that encode historical narratives beyond their administrative functions, this comprehensive review advances our understanding of ancient Indian society. The paper's conclusion underscores the implications of these findings for future linguistic and archaeological research.
Experiental Civic Learning by using "Projekt: Aktive Bürger"
Creators: name: Koopmann, Klaus

description: Various social and political developments seem to sum up to a process of 'de-civilization' which impede - rather than facilitate - the project of a humane and democratic society. In order to make this project a successful one it is necessary to reclaim citizens as politically acting subjects. The ability to act as enlightened and autonomous citizens will be sustainably acquired by experiencing extensive participation in society and in politics. Civic education should foster this process of 'revi-talization of citizenship' by offering youth meaningful participatory experiences of social and po-litical relevance. That is: Civic education should create, organize and offer learning strategies that are oriented towards the notion of reflective acting as experiential learning. Experiential learning processes, aimed at the sustainable acquisition of competencies which are relevant in politics and civil society, will particularly unfold in the course of the (inter)active dealing of the individual(s) with the authentic political and social problems and processes that surround and concern them. This also includes reflection and co-operation. One example of how to practice an experiential and prob-lem-centred learning strategy is well being demonstrated by the civic education program "Projekt: Aktive Bürger", the German adaptation of "We the People ... Project Citizen" designed by the American Center for Civic Education.
