description: Funktionale Zusammenhänge sind Teil unseres Alltags. Bereits Kindergartenkinder machen die Erfahrung, dass ihre Körpergröße in Abhängigkeit von ihrem Alter zunimmt. Auch im Mathematikunterricht spielen funktionale Zusammenhänge eine wichtige und durchgehende Rolle. Von der Grundschule an setzen sich Lernende mit Mustern auseinander, erkennen darin Regelmäßigkeiten und setzen die Muster entsprechend fort. In der gymnasialen Oberstufe ist ohne ein grundlegendes Verständnis funktionaler Zusammenhänge eine Auseinandersetzung mit der Analysis nicht mehr vorstellbar. Im Lernprozess zu funktionalen Zusammenhängen kann eine Vielzahl von Fehlvorstellungen auftreten. Wir nennen hier beispielhaft den Graph-als-Bild- Fehler, der die Lernenden dazu verleitet, einen Funktionsgraphen nicht als Repräsentationsform eines funktionalen Zusammenhangs, sondern als Bild einer Situation zu interpretieren. Außerdem ist häufig die Fehlvorstellung illusion of linearity anzutreffen, bei der Lernende fälschlicherweise auch nicht-lineare funktionale Zusammenhänge als linear betrachten. (vgl. Hofmann & Roth, 2021 für eine Zusammenstellung typischer Schülerfehler im Zusammenhang mit Funktionen). Es wird deutlich, dass funktionales Denken, also die Fähigkeit mit Funktionen zu denken und zu arbeiten, relevant, allgegenwärtig und nicht trivial ist (Roth & Lichti, 2021).
Delaware River Creel Survey 2002

description: An access point survey in conjunction with an aerial effort survey was used to estimate effort, catch and harvest of American shad, hickory shad, river herring, striped bass, and other species targeted by anglers in the Delaware River during 2002. Catch and harvest rates were estimated from 2,353 completed trips based on interviews of anglers at a random sample of access points over time in the tidal and non-tidal portion of the river. The harvest rates were low for American shad (19%), hickory shad (0), and striped bass (1%), but substantial for river herring (65%). Results show a similar catch rate for American shad but a decline in the total catch as compared to surveys in 1986 and 1995, resulting from a reduction in fishing effort.

description: We obtain solutions of the time-dependent Einstein Field Equations which satisfy the Karmarkar condition via the method of Lie symmetries. Spherically symmetric spacetime metrics are used with metric functions set to impose conformal flatness, Weyl-free collapse and shear-free collapse. In particular, a solution was found which satisfies the heat-flux boundary condition of Santos, and a radiating stellar model was then obtained and investigated. Solutions obtained which do not allow for the application of the junction conditions at a boundary surface may lend themselves to cosmological models. This is a first attempt in generating solutions satisfying the Karmarkar condition via the method of Lie symmetries and our example of a radiating model highlights the viability of this method.

description: We present a new Planck CMB lensing-CMB temperature cross-correlation likelihood that can be used to constrain cosmology via the Integrated Sachs-Wolfe (ISW) effect. CMB lensing is an excellent tracer of ISW, and we use the latest PR4 Planck data maps and lensing reconstruction to produce the first public Planck likelihood to constrain this signal. We demonstrate the likelihood by constraining the CMB background temperature from Planck data alone, where the ISW-lensing cross-correlation is a powerful way to break the geometric degeneracy, substantially improving constraints from the CMB and lensing power spectra alone.

description: Despite the huge success of enantioselective Bronsted acid catalysis, experimental data about structures and activation modes of substrate/catalyst complexes in solution are very rare. Here, for the first time, detailed insights into the structures of imine/Bronsted acid catalyst complexes are presented on the basis of NMR data and underpinned by theoretical calculations. The chiral Bronsted acid catalyst R-TRIP (3,3'-bis(2,4,6-triisopropylphenyl)-1,1'-binaphthyl-2,2'-diyl hydrogen phosphate) was investigated together with six aromatic imines. For each investigated system, an E-imine/R-TRIP complex and a Z-imine/R-TRIP complex were observed. Each of these complexes consists of two structures, which are in fast exchange on the NMR time scale; i.e., overall four structures were found. Both identified E-imine/R-TRIP structures feature a strong hydrogen bond but differ in the orientation of the imine relative to the catalyst. The exchange occurs by tilting the imine inside the complex and thereby switching the oxygen that constitutes the hydrogen bond. A similar situation is observed for all investigated Z-imine/R-TRIP complexes. Here, an additional exchange pathway is opened via rotation of the imine. For all investigated imine/R-TRIP complexes, the four core structures are highly preserved. Thus, these core structures are independent of electron density and substituent modulations of the aromatic imines. Overall, this study reveals that the absolute structural space of binary imine/TRIP complexes is large and the variations of the four core structures are small. The high mobility is supposed to promote reactivity, while the preservation of the core structures in conjunction with extensive pi-pi and CH-pi interactions leads to high enantioselectivities and tolerance of different substrates.

description: Mit der COVID-19-Pandemie und dem plötzlich erforderlichen Distanzunterricht im Frühjahr 2020 wurden verschiedenste Defizite in der digitalen Schulbildung sichtbar. So sahen sich viele Lehrkräfte mit mangelnder technischer Ausstattung als auch der fehlenden technischen Ausbildung konfrontiert (Forsa, 2020). Des Weiteren konnten sie nur auf ein unzureichendes Angebot an digitalen Lernplattformen zurückgreifen und berichteten von einem vermehrten Einsatz von Reproduktionsaufgaben (Barlovits et al., 2021). Sprunghaft rückte die Nutzung und Entwicklung von digitalen Lernplattformen in den vergangenen Jahren sowohl in den öffentlichen als auch den politischen Fokus (WELT, 2020). In einer Bestandsaufnahme einiger bestehender Lernplattformen von Thurm und Graewert (2022) wurde allerdings deutlich, dass das volle Potential von digitalen Lernangeboten bei weitem nicht ausgenutzt wird und auch in der Qualität der Lernangebote teils gravierende Unterschiede bestehen. Thurm und Graewert (2022) fordern daher eine Weiterentwicklung der digitalen Lehr-/Lernumgebungen beziehungsweise eine Neuentwicklung dieser unter Berücksichtigung verschiedener Kriterien. Zu Letzteren gehören mitunter die Qualität der Aufgaben in Bezug auf mögliche Aufgabenformate, die Qualität der Diagnostik, die Adaptivität an die Lernenden, soziales Lernen in Form von Teamarbeit sowie Teamkommunikation und nicht zuletzt die Möglichkeiten der Eigenregulation. Mit dem Wissen um diese Anforderungen für digitale Lernplattformen stellen wir das Projekt ASYMPTOTE und das gleichnamige System für synchrones Distanzlernen vor.

description: Überzeugungen von Mathematiklehrkräften werden wesentliche Einflüsse auf die Unterrichtsgestaltung, das Unterrichtsgeschehen und die Leistungen von Lernenden zugeschrieben (z. B. Dubberke et al., 2008). Forschungsbeiträge beschäftigen sich dabei häufig mit Effekten auf die Struktur des Mathematikunterrichts, auf formulierte Ziele und konkrete Handlungsvorstellungen zur Umsetzung (z. B. Voss et al., 2011). Überzeugungen können als „überdauernde existentielle Annahmen über Phänomene oder Objekte der Welt, die subjektiv für wahr gehalten werden, sowohl implizite als auch explizite Anteile besitzen und die Art der Begegnung mit der Welt beeinflussen“ (Voss et al., 2011, S. 235) verstanden und als Überzeugungen zur Mathematik im Allgemeinen – global – oder für spezifische Bereiche des Mathematikunterrichts beforscht und ausgedeutet werden. Im Sinne einer an die Berufsbedürfnisse angepassten Lehrerbildung erscheint eine Untersuchung von Überzeugungen bereits von angehenden Mathematiklehrkräften – etwa im Zusammenhang mit universitären Lehrveranstaltungen – sinnvoll (Blömeke et al., 2008).

description: We drop the complexification procedure from the Newman-Janis algorithm and introduce more physical arguments and symmetry properties, and we show how one can generate regular and singular rotating black hole and non-black-hole solutions in Boyer-Lindquist coordinates. We focus on generic rotating regular black holes and show that they are regular on the Kerr-like ring but physical entities are undefined there. We show that rotating regular black holes have much smaller electric charges, and, with increasing charge, they turn into regular non-black-hole solutions well before their Kerr-Newman counterparts become naked singularities. No causality violations occur in the region inside a rotating regular black hole. The separability of the Hamilton-Jacobi equation for neutral particles is also carried out in the generic case, and the innermost boundaries of circular orbits for particles are briefly discussed. Other, but special, properties pertaining to the rotating regular counterpart of the Ayón-Beato--Garc\'ıa regular static black hole are also investigated.

description: Funktionales Denken kann als Paradebeispiel einer fundamentalen Idee betrachtet werden, da es bei der Bearbeitung vielfältiger inner- und außermathematischer Problemstellungen über verschiedene Inhaltsbereiche hinweg Anwendung findet (Krüger, 2019; Vohns, 2016). In der Literatur gibt es unterschiedliche Beschreibungen und Schwerpunktsetzungen in Bezug auf dieses Konstrukt, was u.a. zu verschiedenen Unterrichtsgestaltungen und Förderansätzen führen mag. Im EU-Projekt FunThink werden Lehr-Lern-Materialien zur Förderung des funktionalen Denkens entwickelt. Um Beschreibungen und Ansätze aus der Literatur um (nationale) Besonderheiten und Konkretisierungen für die Praxis zu ergänzen, wurden Interviews mit 34 Expert* innen aus dem mathematikbezogenen Bildungsbereich in fünf europäischen Ländern geführt (Deutschland, Niederlande, Polen, Slowakei, Zypern). Auf diesem Weg konnte zudem exemplarisch für die intendierte Materialentwicklung analysiert werden, inwieweit in der Praxis Nachholbedarf in Bezug auf die Konzeptualisierung und Förderung funktionalen Denkens besteht. In diesem Beitrag werden erste Ergebnisse dieser Studie vorgestellt.

description: This report discusses and quantifies the incremental costs and benefits between the proposed 20% Renewable [Energy] Portfolio Standard (RPS) and the existing RPS. The objective of the report is to assess the costs and benefits of increasing the renewable energy portfolio standard from its current level to 20% by the year 2020, including impacts on the cost of electricity and the environmental and economic development benefits. Findings suggest that the proposed 20% RPS would raise electricity prices 3.7% in 2020 and have no measurable impact on the growth of New Jersey's economy. Also, if natural gas prices rise to levels assumed in the high energy price scenario, the proposed 20% RPS has a positive impact on the NJ economy because electricity prices would be lower than under the existing RPS scenario.

An iterative method for the construction of N-body galaxy models in collisionless equilibrium

Year: 2014
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: (Abridged) We describe a new iterative approach for the realization of equilibrium N-body systems for given density distributions. Our method uses elements of Schwarzschild's technique and of the made-to-measure method, but is based on a different principle. Starting with some initial assignment of particle velocities, we calculate their orbits using a flexible tree-based force algorithm in the stationary potential of the target density distribution. The difference of the time-averaged density response produced by these orbits with respect to the initial density configuration is characterized through a merit function, and a stationary solution of the collisionless Boltzmann equation is found by minimizing this merit function directly by iteratively adjusting the initial velocities. Because the distribution function is in general not unique for a given density structure, we augment the merit function with additional constraints that single out a desired target solution. We do this for broad classes of axisymmetric density distributions by numerically solving the Jeans equations to obtain the second velocity moments, which are then imposed as further constraints in the optimization process. The velocity adjustment is carried out with a stochastic process in which new velocities are randomly drawn from an approximate solution of the distribution function, but are kept only when they improve the fit. Our method converges rapidly and is flexible enough to allow the construction of solutions with third integrals of motion, including disk galaxies with realistic velocity distributions. We demonstrate that the new method reproduces analytic distribution functions where they are known (such as the Hernquist sphere), and that it yields very stable N-body realizations for a variety of examples of compound galaxy models, considerably improving on widely used moment-based approaches.

description: Hydrogen bonding plays a crucial role in Bronsted acid catalysis. However, the hydrogen bond properties responsible for the activation of the substrate are still under debate. Here, we report an in depth study of the properties and geometries of the hydrogen bonds in (R)-TRIP imine complexes (TRIP: 3,3'-Bis(2,4,6-triisopropylphenyl)-1,1'-binaphthyl-2,2'-diylhydrogen phosphate). From NMR spectroscopic investigations H-1 and N-15 chemical shifts, a Steiner-Limbach correlation, a deuterium isotope effect as well as quantitative values of (1)J(NH), (2h)J(PH) and (3h)J(PN) were used to determine atomic distances (r(OH), r(NH), r(NO)) and geometry information. Calculations at SCS-MP2/CBS//TPSS-D3/def2-SVP-level of theory provided potential surfaces, atomic distances and angles. In addition, scalar coupling constants were computed at TPSS-D3/IGLO-III. The combined experimental and theoretical data reveal mainly ion pair complexes providing strong hydrogen bonds with an asymmetric single well potential. The geometries of the hydrogen bonds are not affected by varying the steric or electronic properties of the aromatic imines. Hence, the strong hydrogen bond reduces the degree of freedom of the substrate and acts as a structural anchor in the (R)-TRIP imine complex.

description: Operational disruptions can have serious repercussions for firms over extended periods of time. In this work, we develop a multi-period model of operational risk. We define the loss process of operational disruptions as a sum of events triggering single and multiple losses. We empirically validate our approach using an extensive data set of operational disruptions experienced by firms from the financial services and manufacturing industry sectors. The results of our simulations point out that operational risk is significantly underestimated if the events leading to multiple losses are not accounted for in the firms' long-term capital planning.

description: The ultimate purpose of the statistical analysis of ordinal patterns is to characterize the distribution of the features they induce. In particular, knowing the joint distribution of the pair Entropy-Statistical Complexity for a large class of time series models would allow statistical tests that are unavailable to date. Working in this direction, we characterize the asymptotic distribution of the empirical Shannon's Entropy for any model under which the true normalized Entropy is neither zero nor one. We obtain the asymptotic distribution from the Central Limit Theorem (assuming large time series), the Multivariate Delta Method, and a third-order correction of its mean value. We discuss the applicability of other results (exact, first-, and second-order corrections) regarding their accuracy and numerical stability. Within a general framework for building test statistics about Shannon's Entropy, we present a bilateral test that verifies if there is enough evidence to reject the hypothesis that two signals produce ordinal patterns with the same Shannon's Entropy. We applied this bilateral test to the daily maximum temperature time series from three cities (Dublin, Edinburgh, and Miami) and obtained sensible results.

description: A practical use of the entanglement entropy in a 1d quantum system is to identify the conformal field theory describing its critical behavior. It is exactly $(c/3)\ln \ell$ for an interval of length $\ell$ in an infinite system, where $c$ is the central charge of the conformal field theory. Here we define the geometric mutual information, an analogous quantity for classical critical points. We compute this for 2d conformal field theories in an arbitrary geometry, and show in particular that for a rectangle cut into two rectangles, it is proportional to $c$. This makes it possible to extract $c$ in classical simulations, which we demonstrate for the critical Ising and 3-state Potts models.

description: Während das Anfertigen einer Skizze im Allgemeinen als leistungsstarke Strategie zur Lösung mathematischer Probleme gilt, stellten De Bock et al. (2003) überraschenderweise fest, dass sich das Zeichnen einer Skizze negativ auf die Leistung von Lernenden beim Lösen von Aufgaben zu nicht linearen Geometrieproblemen auswirkt. Als wichtigen Grund für diesen negativen Effekt erkannten die Autoren, dass das Anfertigen einer Skizze die Tendenz zur sogenannten Linearen Übergeneralisierung verstärkte. Eine an die Ergebnisse der Analyse von De Bock et al. (2003) anknüpfende Studie von Krawitz & Schukajlow (2020) deutete an, dass das Zeichnen einer Skizze neben Linearen Übergeneralisierungen auch andere Fehler triggern muss. Ziel dieser Untersuchung ist es, weitere Faktoren für den negativen Effekt der Skizzenerstellung auf die Leistung zu finden. Diese sollen perspektivisch Ansätze für Interventionen geben, die eine produktive Nutzung selbst erstellter Skizzen bei der Bearbeitung von nicht-linearen Geometrieproblemen ermöglichen. Dafür werden in einem ersten Schritt die Daten der Studie von Krawitz & Schukajlow (2020) reanalysiert.

description: Earlier comparisons of galatic rotation curves with MOND have arrived at the conclusion that the parameter a_0 lies within ~20% of cH_0/2π, where c is the velocity of light and H_0 is the Hubble constant. It is proposed here that, for this value of H_0, signals propagating around the periphery of the Universe are phase locked by the graviton-nucleon interaction.

description: Das Beurteilen individueller Lernprozesse und -ergebnisse ist eine anspruchsvolle Aufgabe für Lehrkräfte (Südkamp et al., 2012). Im Mathematikunterricht nutzen Lehrkräfte häufig schriftliche Aufgaben, um solche Lernprozesse bei den Schülerinnen und Schülern anzuregen und zu beurteilen. Während die Verwendung von Aufgaben zum Lernen schon Gegenstand zahlreicher Studien war (z. B. Neubrand et al., 2013), gibt es nur wenige Erkenntnisse darüber, wie Lehrkräfte Aufgaben zum Diagnostizieren verwenden. In einer aufgabenbasierten Diagnosesituation sollten Lehrkräfte in der Lage sein, mathematische Aufgaben gezielt auszuwählen und zu evaluieren, um damit relevante Informationen über die mathematischen Fähigkeiten der Schülerinnen und Schüler zu generieren. In diesem Beitrag werden erste Ergebnisse einer Studie berichtet, die das Ziel hat, Prozesse der Diagnose in einer aufgabenbasierten Diagnosesituation im Rahmen einer digitalen Simulation zu analysieren.

description: The search of the anomalous couplings is one of the possible ways to find any deviation from the Standard Model. The effective field theory is used to parameterize the anomalous couplings in the Lagrangian with the operators of higher dimensions, constructed from the SM fields. In the classical way, the limits on the Wilson coefficients of these operators are set based on beyond the Standard Model contributions induced for signal process, whereas the ones induced for background processes are assumed to be negligible. This article provides a study of the corrections to the limits on Wilson coefficients by accounting beyond the Standard Model contributions induced for background processes. The studies of $Z(ν\barν)γjj$ and $W(\ellν)γjj$ productions in $pp$ collisions with $\sqrt{s}=13$ TeV and conditions of the ATLAS experiment at the LHC are used as example. Cases of collected during Run II and expected from Run III integrated luminosities of 139 fb$^{-1}$ and 300 fb$^{-1}$ are considered. The expected 95% CL limits on coefficients $f_\text{T0}/Λ^4$, $f_\text{T5}/Λ^4$, $f_\text{M0}/Λ^4$ and $f_\text{M2}/Λ^4$ are obtained both in classical way and in the way, where the corrections from background anomalous contributions are applied. Corrected one-dimensional limits from $Z(ν\barν)γjj$ and $W(\ellν)γjj$ productions are up to 9.1% and 4.4% (depending on operator) tighter than the classical ones respectively. Corrected combined limits are up to 3.0% (depending on operator) tighter than the classical ones. Corrections to two-dimensional limits are also obtained, corrected contours are more stringent, than the classical ones, and the maximal improvement is of 17.2%.

description: The importance of human mobility analyses is growing in both research and practice, especially as applications for urban planning and mobility rely on them. Aggregate statistics and visualizations play an essential role as building blocks of data explorations and summary reports, the latter being increasingly released to third parties such as municipal administrations or in the context of citizen participation. However, such explorations already pose a threat to privacy as they reveal potentially sensitive location information, and thus should not be shared without further privacy measures. There is a substantial gap between state-of-the-art research on privacy methods and their utilization in practice. We thus conceptualize a standardized mobility report with differential privacy guarantees and implement it as open-source software to enable a privacy-preserving exploration of key aspects of mobility data in an easily accessible way. Moreover, we evaluate the benefits of limiting user contributions using three data sets relevant to research and practice. Our results show that even a strong limit on user contribution alters the original geospatial distribution only within a comparatively small range, while significantly reducing the error introduced by adding noise to achieve privacy guarantees.

description: Driven by the Beam Energy Scan (BES) program at the RHIC, researches and discussions on the QCD phase diagram have flourished recently. In order to provide a reference from microscopic transport models, we performed a systematic analysis, using a multiphase transport (AMPT) model for the particle yields and a statistical model (THERMUS) for the thermal fit, for Au+Au collisions at $\sqrt{s_{\text{NN}}}$=7.7-200 GeV. It is found that at a fixed collision centrality the chemical freeze-out parameter, temperature $T_{\text{ch}}$, increases with collision energy and somehow saturates at certain values of $T_{\text{ch}}$ in collisions near $\sqrt{s_{\text{NN}}}$=10 GeV, indicating the limiting temperature in hadronic interactions; meanwhile the baryon chemical potential $μ_B$ decrease with the collision energy. The saturation temperature is also found to be dependent on partonic interaction. At a given collision energy, it is found that both $T_{\text{ch}}$ and $μ_B$ decrease towards more peripheral collisions in the grand canonical approach. The energy and centrality dependence of other chemical freeze-out parameters, strangeness chemical potential $μ_S$, strangeness undersaturation factor $γ_S$, and the volume of the fireball $V$ are also presented in this paper. The chemical potential ratio $μ_s/μ_B$ is also compared with lattice QCD calculation. The AMPT default model gives better descriptions on both the particle yields and the chemical freeze-out parameters than those from the AMPT string-melting model.

description: The emergence of new SARS-CoV-2 variants and the replacement of preceding isolates have been observed through B.1.1.7, B.1.351, B.1.617.2, and B.1.1.529 lineages (corresponding to alpha, beta, delta, and omicron variants of concern (VoC), respectively). However, there is still a lack of biological evidence to which extent those VoC differ from the ancestral lineages. By exploiting human airway epithelial cell (HAEC) cultures, which closely resemble the human airway architecture and physiology, we report distinctive SARS-CoV-2 tropism in different respiratory tissues. In general, SARS-CoV-2 VoC predominantly infect and replicate in HAEC better than the progenitor USA-WA1 isolate or the BavPat1 isolate, which contains the D614G mutation, even though there is little to no difference between variants regarding their infectivity (i.e., virion-per-vRNA copy ratio). We also observe differential tissue-specific innate immunity activation between the upper and lower respiratory tissues in the presence of the virus. Our study provides better comprehension of the behavior of the different VoC in this physiologically relevant ex vivo model.

description: Compared with the charmed baryons, the bottom baryons are not very well known, either experimentally or theoretically. In this paper, we investigate the dipion strong decays of the P-wave and D-wave excited bottom baryons in the framework of the QPC model. We also extend the same analysis to the charmed baryons.
