description: Explored orthotropic shallow shells of double curvature, as well as cylindrical panels that are reinforced from the concave side by an orthogonal grid of stiffeners. The external transverse load acting on the structure is uniformly distributed and has a linear dependency on time. A geometrically nonlinear variant of the model which also takes into account orthotropy of the material and transverse shears are considered. The model is presented as a functional of total deformation energy of the shell. The algorithm for studying the mathematical model is based on the L.V. Kantorovich method and the Rosenbrock method. The proposed algorithm was implemented in the analytical computing environment Maple 2016. The calculations showed a significant increase in critical load values for the loss of stability when the shell is reinforced with stiffeners.

description: Spätestens, wenn die Schüler*innen, die sich in der Fridays-for-Future-Bewegung (FFF-Bewegung) engagieren, dem Unterricht fernbleiben, müssen die schulischen Akteur*innen, aufgrund der in Deutschland geltenden Schulpflicht, reagieren. Im folgenden Beitrag werden die möglichen Spannungsverhältnisse zwischen der FFF-Bewegung und der Schule – neben der Schulpflicht – aus einer hegemonietheoretischen Perspektive betrachtet. Dabei wird auch der Frage nachgegangen, welche Handlungsoptionen (und Grenzen) der Schule in dem fest institutionalisierten Kontext gesetzt sind, wenn sie die Kinder und Jugendlichen bei der Artikulation politischer Interessen unterstützen möchte. School actors must react, at the latest, when students involved in the Fridays for Future movement stay away from class. Therefore, the following article will examine the possible tensions between the FFF-movement and the school – from a hegemony-theorical perspective. In doing so, it will also explore the question of what possibilities (and limits) of action school have when they want to support children and young people in articulating their political interests.

description: Many debris discs reveal a two-component structure, with an outer Kuiper-belt analogue and a warm inner component whose origin is still a matter of debate. One possibility is that warm emission stems from an "asteroid belt" closer in to the star. We consider a scenario in which a set of giant planets is formed in an initially extended planetesimal disc. These planets carve a broad gap around their orbits, splitting up the disc into the outer and the inner belts. After the gas dispersal, both belts undergo collisional evolution in a steady-state regime. This scenario is explored with detailed collisional simulations involving realistic physics to describe a long-term collisional depletion of the two-component disc. We find that the inner disc may be able to retain larger amounts of material at older ages than thought before on the basis of simplified analytic models. We show that the proposed scenario is consistent with a suite of thermal emission and scattered light observational data for a bright two-temperature debris disc around a nearby solar-type star q$^1$ Eridani. This implies a Solar System-like architecture of the system, with an outer massive "Kuiper belt", an inner "asteroid belt", and a few Neptune- to Jupiter-mass planets in between.

On the Astrid asteroid family
Creators: name: Carruba, V.
Publisher: name: arXiv
Year: 2016
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: Among asteroid families, the Astrid family is peculiar because of its unusual inclination distribution. Objects at $a\simeq$~2.764 au are quite dispersed in this orbital element, giving the family a "crab-like" appearance. Recent works showed that this feature is caused by the interaction of the family with the $s-s_C$ nodal secular resonance with Ceres, that spreads the inclination of asteroids near its separatrix. As a consequence, the currently observed distribution of the $v_W$ component of terminal ejection velocities obtained from inverting Gauss equation is quite leptokurtic, since this parameter mostly depends on the asteroids inclination. The peculiar orbital configuration of the Astrid family can be used to set constraints on key parameters describing the strength of the Yarkovsky force, such as the bulk and surface density and the thermal conductivity of surface material. By simulating various fictitious families with different values of these parameters, and by demanding that the current value of the kurtosis of the distribution in $v_W$ be reached over the estimated lifetime of the family, we obtained that the thermal conductivity of Astrid family members should be $\simeq$ 0.001 W/m/K, and that the surface and bulk density should be higher than 1000 kg/m$^{3}$. Monte Carlo methods simulating Yarkovsky and stochastic YORP evolution of the Astrid family show its age to be $T$ = 140$\pm$30 Myr old, in good agreement with estimates from other groups. Its terminal ejection velocity parameter is in the range $V_{EJ}= 5^{+17}_{-5}$~m/s.] Values of $V_{EJ}$ larger than 25 m/s are excluded from constraints from the current inclination distribution.

Inklusion und Nachhaltigkeit
Creators: name: Feuser, Georg
Publisher: name: WE_OS Jahrbuch
Year: 2022

description: Fragen der Nachhaltigkeit sind heute in vielen wissenschaftlichen Disziplinen und Praxisfeldern geradezu omnipräsent. Der Begriff selbst ist nur aus seiner Entstehungsgeschichte heraus einigermaßen zu präzisieren, und er wird, dem Inklusionsbegriff vergleichbar, heute weitgehend inflationär gebraucht. Unter Aspekten der Schärfung beider Begriffe ist es dennoch sinnvoll, sie auch im Feld der Erziehungswissenschaft in Beziehung zu setzen und im Zusammenhang mit pädagogisch relevanten Problemstellungen zu präzisieren. Entsprechend versucht dieser Beitrag, unter dem Primat der Schaffung von Bildungsoptionen für alle und unter Einbezug von Fragen der Kultur und ethischen Dimensionen, die in ökonomischen, wirtschafts- und wachstumsfokussierten Fragestellungen weitgehend verloren gehen, einen integrierten Ansatz aufzuzeigen. Das bedeutet, auch in Feldern der Pädagogik zu klären, was letztlich Bestand haben soll, um im Sinne von Heydorn „die unmenschliche Repression der Vergangenheit als Kulturversagung” (1980, S. 180) aufzuheben – und damit auch die als exzessiv zu bezeichnenden, das ganze Schulsystem durchziehenden Selektions- und Exklusionsprozesse, was von Inklusion zu sprechen dann nicht mehr erforderlich machen würde. Issues of sustainability are nearly omnipresent in many scientific disciplines and fields of practice today. The term itself can only be reasonably specified by looking at its genesis; it is largely used in an inflationary manner today. In order to clarify both terms, it is sensible, however, to relate them also in the field of educational science and to specify them in the context of pedagogically relevant problems. Thus, this contribution tries to point out an integrated approach – under the primacy of educational chances for all, including cultural issues and ethical dimensions, which get widely lost in the economical, profitable growth-focused discussions. This means to clarify also in fields of education what shall endure in the end, in order to cancel “the inhumane repression of the past as a refusal of culture” (Heydorn, 1980, p. 180), and thus the excessive processes of selection and exclusion, which pervade the whole educational system – this means that it would no longer be necessary to talk about inclusion.

First limits on the occurrence rate of short-period planets orbiting brown dwarfs

description: Planet formation theories predict a large but still undetected population of short-period terrestrial planets orbiting brown dwarfs. Should specimens of this population be discovered transiting relatively bright and nearby brown dwarfs, the Jupiter-size and the low luminosity of their hosts would make them exquisite targets for detailed atmospheric characterisation with JWST and future ground-based facilities. The eventual discovery and detailed study of a significant sample of transiting terrestrial planets orbiting nearby brown dwarfs could prove to be useful not only for comparative exoplanetology but also for astrobiology, by bringing us key information on the physical requirements and timescale for the emergence of life. In this context, we present a search for transit-signals in archival time-series photometry acquired by the Spitzer Space Telescope for a sample of 44 nearby brown dwarfs. While these 44 targets were not particularly selected for their brightness, the high precision of their Spitzer light curves allows us to reach sensitivities below Earth-sized planets for 75% of the sample and down to Europa-sized planets on the brighter targets. We could not identify any unambiguous planetary signal. Instead, we could compute the first limits on the presence of planets on close-in orbits. We find that within a 1.28 day orbit, the occurrence rate of planets with a radius between 0.75 and 3.25 R$_\oplus$ is η < 67 $\pm$ 1%. For planets with radii between 0.75 and 1.25 R$_\oplus$, we place a 95% confident upper limit of η < 87 $\pm$ 3%. If we assume an occurrence rate of η = 27% for these planets with radii between 0.75 and 1.25 R$_\oplus$, as the discoveries of the Kepler-42b and TRAPPIST-1b systems would suggest, we estimate that 175 brown dwarfs need to be monitored in order to guarantee (95%) at least one detection.

description: Since 2004, the images obtained by Cassini spacecraft's on-board cameras have revealed the existence of several small satellites in the Saturn system. Some of these small satellites are embedded in arcs of particles. While these satellites and their arcs are known to be in corotation resonances with Mimas, their origin remains unknown. This work investigates one possible process for capturing bodies into a corotation resonance, which involves raising the eccentricity of a perturbing body. Therefore, through numerical simulations and analytical studies, we show a scenario that the excitation of Mimas' eccentricity could capture particles in a corotation resonance and given a possible explanation for the origin for the arcs.

Politics of Redress: Analyzing the Civil Liberties Act of 1988 as a Model to Resolve the “Comfort Women” Issue Between Japan and South Korea
Creators: name: Jones, Derek
Publisher: name: University of Chicago
Year: 2022

description: The “comfort women” issue continues to impact Japan and South Korea’s relationship almost eighty years after the Pacific War ended. Much scholarship has studied the “comfort women” system and the redress movement, but few have proposed solutions to the “comfort women” issue other than continuously criticizing the Japanese government or the presence of nationalism in “comfort women” issue discourse. In 2007, the US House of Representatives passed a resolution condemning the Japanese government’s inability to resolve the issue. Congressman Mike Honda—a sponsor of the resolution—argued that Japan needed to take “historical responsibility” for the “comfort women” issue and suggested the US government’s apology for Japanese-American internment (the Civil Liberties Act of 1988) as an example to follow. This paper examines whether the Civil Liberties Act of 1988 could serve as a feasible model to resolve the “comfort women” issue between Japan and South Korea. In its examination, this paper first contrasts the Japanese government’s past apologies and resolution attempts to the Civil Liberties Act of 1988’s measures. Second, this paper analyzes Japan’s current political context to identify reasons to be pessimistic or optimistic a resolution modeled after the Civil Liberties Act of 1988 could be passed today. Ultimately, this paper argues that legislation modeled after the Civil Liberties Act of 1988 could resolve the “comfort women” issue between Japan and South Korea, and this paper posits numerous reasons to be optimistic that such legislation could be passed by the Japanese government today.
Least Square Estimation-Based SDP Cuts for SOCP Relaxation of AC OPF

description: This paper presents a method that generates affine inequalities to strengthen the second-order conic programming (SOCP) relaxation of an alternating current optimal power flow (AC OPF) problem. The affine inequalities serve as cuts to get rid of points outside of the feasible region of AC OPF with semi-definite programming (SDP) relaxation. Hence, the affine inequalities are names as SDP cuts. While AC OPF with SDP relaxation has a high computational complexity, AC OPF with SOCP has a much lower computational complexity. Recent research has found that the feasible region of SDP relaxation is contained inside the feasible region of the SOCP relaxation. Therefore, the integration of SDP cuts into SOCP relaxation provides better scalability compared to the SDP relaxation and a tighter gap compared to the SOCP relaxation. The SDP cuts are generated by solving least square estimation (LSE) problems at cycle basis and further exploring the geometric characteristic of LSE. General feasibility cuts generating method is also employed for analysis. We found that the SDP cuts generated by LSE method are indeed feasibility cuts. The SDP cuts effectively reduce the search space. Case studies of systems with several buses to hundreds of buses have demonstrated the method is very effective in reducing the gaps.

description: We propose a new sparse estimation method, termed MIC (Minimum approximated Information Criterion), for generalized linear models (GLM) in fixed dimensions. What is essentially involved in MIC is the approximation of the $\ell_0$-norm with a continuous unit dent function. Besides, a reparameterization step is devised to enforce sparsity in parameter estimates while maintaining the smoothness of the objective function. MIC yields superior performance in sparse estimation by optimizing the approximated information criterion without reducing the search space and is computationally advantageous since no selection of tuning parameters is required. Moreover, the reparameterization tactic leads to valid significance testing results that are free of post-selection inference. We explore the asymptotic properties of MIC and illustrate its usage with both simulated experiments and empirical examples.

description: In 1970 Zel'dovich published a far-reaching paper presenting a simple equation describing the nonlinear growth of primordial density inhomogeneities. The equation was remarkably successful in explaining the large scale structure in the Universe that we observe: a Universe in which the structure appears to be delineated by filaments and clusters of galaxies surrounding huge void regions. In order to concretise this impression it is necessary to define these structural elements through formal techniques with which we can compare the Zel'dovich model and N-body simulations with the observational data. We present an overview of recent efforts to identify voids, filaments and clusters in both the observed galaxy distribution and in numerical simulations of structure formation. We focus, in particular, on methods that involve no fine-tuning of parameters and that handle scale dependence automatically. It is important that these techniques should result in finding structures that relate directly to the dynamical mechanism of structure formation.

description: Similar to nitrogen-vacancy centers in diamond and impurity atoms in silicon, interstitial gallium deep paramagnetic centers in GaAsN have been proven to have useful characteristics for the development of spintronic devices. Among other interesting properties, under circularly polarized light, gallium centers in GaAsN act as spin filters that dynamically polarize free and bound electrons reaching record spin polarizations (100\%). Furthermore, the recent observation of the amplification of the spin filtering effect under a Faraday configuration magnetic field has suggested that the hyperfine interaction that couples bound electrons and nuclei permits the optical manipulation of its nuclear spin polarization. Even though the mechanisms behind the nuclear spin polarization in gallium centers are fairly well understood, the origin of nuclear spin relaxation and the formation of an Overhauser-like magnetic field remain elusive. In this work we develop a model based on the master equation approach to describe the evolution of electronic and nuclear spin polarizations of gallium centers interacting with free electrons and holes. Our results are in good agreement with existing experimental observations. In regard to the nuclear spin relaxation, the roles of nuclear dipolar and quadrupolar interactions are discussed. Our findings show that, besides the hyperfine interaction, the spin relaxation mechanisms are key to understand the amplification of the spin filtering effect and the appearance of the Overhauser-like magnetic field. Based on our model's results we propose an experimental protocol based on time resolved spectroscopy. It consists of a pump-probe photoluminescence scheme that would allow the detection and the tracing of the electron-nucleus flip-flops through time resolved PL measurements.

description: Sky-coverage in laser-assisted AO observations largely depends on the system's capability to guide on the faintest natural guide-stars possible. Here we give an up-to-date status of our natural guide-star processing tailored to the European-ELT's visible and near-infrared (0.47 to 2.45 μm) integral field spectrograph - Harmoni. We tour the processing of both the isoplanatic and anisoplanatic tilt modes using the spatio-angular approach whereby the wave-front is estimated directly in the pupil plane avoiding a cumbersome explicit layered estimation on the 35-layer profiles we're currently using. Taking the case of Harmoni, we cover the choice of wave-front sensors, the number and field location of guide-stars, the optimised algorithms to beat down angular anisoplanatism and the performance obtained with different temporal controllers under split high-order/low-order tomography or joint tomography. We consider both atmospheric and far greater telescope wind buffeting disturbances. In addition we provide the sky-coverage estimates thus obtained.

description: Aims. Polarimetric characteristics of comets at large heliocentric distances is a relatively unexplored area; we extend the idea by adding and analysing the data for three Jupiter family comets (JFCs). Methods. With the FORS2 instrument of the ESO VLT, we performed quasi-simultaneous photometry and polarimetry of three active JFCs 67P/Churyumov-Gerasimenko, 74P/Smirnova-Chernykh, and 152P/Helin-Lawrence. Results. We obtained in total 23 polarimetric measurements at different epochs, covering a phase-angle range ~1 -16 degrees and heliocentric distances from 3 to 4.6 au. From our observations we obtained both colour and polarimetric maps to look for structures in the comae and tails of the comets. Conclusions. 74P/Smirnova-Chernykh and 152P/Helin-Lawrence exhibit enough activity at large heliocentric distances to be detectable in polarimetric measurements. Polarimetric and colour maps indicate no evidence of dust particle
Nonlinearity in judgments and criteria: A machine learning approach

Year: 2022
Subjects: subject: Social and Behavioral Sciences

description: We plan to examine two databases that include both experts' judgments and the criteria which they judge, using both linear and non-linear machine learning models. We distinguish between two cases. In the first, judgments are based on subjective inputs (i.e. inputs that were generated by the judge) and in the second they are based on objective inputs (i.e., inputs that were measured independently). We hypothesize that in the second case, but not in the first case, non-linear models (e.g., random forest, xgboost) will better explain the judgment than a linear (logistic) model. On the other hand, in explaining the criteria there will be little differences between nonlinear and linear models.

The simulation code used the Lagrangian Total Variation Diminishing (LTVD) and remap routine, which enabled us to attain high accuracy in capturing shocks and to handle the angular momentum distribution correctly. Inviscid shock-free accretion disk solution produced a thick disk structure, while the viscous shock-free solution attained a Bondi-like structure, but in either case, no jet activity nor any QPO-like activity developed. The steady state shocked solution in the inviscid, as well as, in the viscous regime, matched theoretical predictions well. However, increasing viscosity renders the accretion shock unstable. Large amplitude shock oscillation is accompanied by intermittent, transient inner multiple shocks. Such oscillation of the inner part of disk is interpreted as the source of QPO in hard X-rays observed in micro-quasars. Strong shock oscillation induces strong episodic jet emission. The jets also showed existence of shocks, which are produced as one shell hits the preceding one. The periodicity of jets and shock oscillation were similar. The jets for higher viscosity parameter are evidently stronger and faster.

Toward theory advancement in mathematical cognition and teacher cognition

description: This thesis is concerned with mathematical cognition and teacher cognition, two of the subfields within mathematics education research. Within each there is a broad range of diverse theories that cultivate varied understandings of complex phenomena in mathematical thinking, learning, and teaching. However, the abundance and diversity of theories can polarize perspectives and foster the development of narrow and restricting theoretical accounts. This thesis uses existing theoretical tensions to stimulate the development of more powerful theoretical accounts by coordinating theoretical perspectives in mathematical cognition and teacher cognition. The thesis consists of three articles, which aim to blend opposing theoretical perspectives to reveal complementarity in the field of mathematical knowing and learning, challenge assumptions to reveal restrictions in the field of teacher knowledge, and portray some complex phenomena that cannot be accounted for using intuitive models of teacher noticing. These articles link apparently disparate approaches, revealing the complexity of the phenomena under consideration and the limitations of existing theoretical accounts for them. The first article blends theoretical perspectives from two local theories of mathematical cognition (abstraction-from-actions and abstraction-from-objects) to present a bi-directional, dynamic, non-linear view of mathematical concept formation. The second article examines teacher cognition, discussing existing conceptualizations of mathematics teacher knowledge, revealing their limitations, and offering alternative views that direct attention to underexplored issues. The third article examines teacher cognition from the perspective of the construct of teacher noticing, drawing on insights from cognitive science and the applied science of human factors to develop a model of teacher noticing which challenges intuitive assumptions and views individual and environment as interdependent and inseparable. It is hoped that these contributions add value to the field by advancing knowledge, providing links between previous conceptualizations, and offering fresh insights and theoretical views.

description: The event-averaged charge state of heavy ion Solar Energetic Particles (SEPs), measured at 1 AU from the Sun, typically increases with the ions' kinetic energy. The origin of this behaviour has been ascribed to processes taking place within the acceleration region. In this paper we study the propagation through interplanetary space of SEP Fe ions, injected near the Sun with a variety of charge states that are uniformly distributed in energy, by means of a 3D test particle model. In our simulations, due to gradient and curvature drifts associated with the Parker spiral magnetic field, ions of different charge propagate with very different efficiencies to an observer that is not magnetically well connected to the source region. As a result we find that, for many observer locations, the 1 AU event-averaged charge state , as obtained from our model, displays an increase with particle energy E, in qualitative agreement with spacecraft observations. We conclude that drift-associated propagation is a possible explanation for the observed distribution of versus E in SEP events, and that the distribution measured in interplanetary space cannot be taken to represent that at injection.

description: We have observed the supernova remnant 3C~396 in the microwave region using the Parkes 64-m telescope. Observations have been made at 8.4 GHz, 13.5 GHz, and 18.6 GHz and in polarisation at 21.5 GHz. We have used data from several other observatories, including previously unpublished observations performed by the Green Bank Telescope at 31.2 GHz, to investigate the nature of the microwave emission of 3C 396. Results show a spectral energy distribution dominated by a single component power law emission with $α=(-0.364 \pm 0.017)$. Data do not favour the presence of anomalous microwave emission coming from the source. Polarised emission at 21.5 GHz is consistent with synchrotron-dominated emission. We present microwave maps and correlate them with infrared (IR) maps in order to characterise the interplay between thermal dust and microwave emission. IR vs. microwave TT plots reveal poor correlation between mid-infrared and microwave emission from the core of the source. On the other hand, a correlation is detected in the tail emission of the outer shell of 3C 396, which could be ascribed to Galactic contamination.

description: The leading position of US dollar as a vehicle currency of international trade has established since 2010. In this paper, I explore shifts of dollar dominance in post-pandemic periods and the roles and invoicing choices of other major currencies. I find that (i) The dominant role of US dollar is consistent in post-COVID periods; (ii) global prices show stronger contemporaneous responses to exchange rate shocks at monthly frequency; (iii) trade prices and volumes respond more quickly and intensively to dollar exchange rate shocks; (iv) there are regional dominant currencies that dominate US dollar in their territory, and major driving forces of invoicing choices in regional-dominant currencies are trade closeness and foreign market shares.

Early child bilingualism: cross-linguistic influence in the simultaneous acquisition of German and English
Creators: name: Genske, Katharina
Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: This thesis investigates cross-linguistic transfer in a bilingual German-English child, Kayla, age 2;10 to 5;06 years. The study draws on data from elicited production probes in addition to spontaneous production data in order to provide a robust data set for investigation. Recent literature assumes that bilingual children differentiate their two languages but endorses the possibility of cross-linguistic influence. It has been proposed that cross-linguistic influence can take one of three forms: transfer, acceleration or delay in the acquisition of certain grammatical constructions (Paradis & Genesee, 1996). The conditions under which cross-linguistic influence occurs have been the subject of considerable debate. One prominent proposal by Hulk & Müller (2000) suggests that overlap in the two languages is a key factor for cross-linguistic influence when it involves a grammatical structure influenced by properties at the interface of linguistic modules. Another recent proposal by Jakubowicz (2006) proposes that derivational complexity is the critical factor conditioning transfer. According to Hulk & Müller’s proposal, verb movement is a candidate for cross-linguistic influence because German and English exhibit considerable surface overlap in regards to word order, giving rise to a potential verb second (V2) analysis of both languages. In addition, V2 implicates the C-domain, which interfaces with pragmatic information. On the other hand, Jakubowicz (2006) does not anticipate transfer of V2 as this involves a derivationally more complex structure. The child data presented in this thesis find support for Hulk & Müller’s proposal. The study focuses on an investigation of the child’s simple negative sentences and interrogatives, both of which potentially expose transfer of V2 properties to English. The current data reveal that the child’s development of German is similar to monolingual peers, while her English exposes crosslinguistic influence. At the first stage, the V2 property is transferred to English, resulting in non-adult like utterances such as *’That opens not’ (KAY, 2;11 years) and *’What wants you eat?’ (KAY, 3;06 years). Second, raising finite main verbs from V to C (via I) in English causes acceleration in the proportion of Inflection in the child’s utterances. In a later stage, the child’s negative sentences conform to the early productions of monolingual English speaking children. The child produces sentential negation exclusively with the adverbial form not, which is consistent with negation in German. This permits later productions such as *’It don’t goes this way’ (KAY, 4;01 years). The child is considerably delayed in the acquisition of the head form of negation (‘n’t’) and consequently use of dosupport and use of negative auxiliaries such as doesn’t.
Voids and the Cosmic Web: cosmic depressions & spatial complexity

description: Voids form a prominent aspect of the Megaparsec distribution of galaxies and matter. Not only do they represent a key constituent of the Cosmic Web, they also are one of the cleanest probes and measures of global cosmological parameters. The shape and evolution of voids are highly sensitive to the nature of dark energy, while their substructure and galaxy population provides a direct key to the nature of dark matter. Also, the pristine environment of void interiors is an important testing ground for our understanding of environmental influences on galaxy formation and evolution. In this paper, we review the key aspects of the structure and dynamics of voids, with a particular focus on the hierarchical evolution of the void population. We demonstrate how the rich structural pattern of the Cosmic Web is related to the complex evolution and buildup of voids.
