Subjects: Didactic of physics, mechanical work, diagrams, semiotic actions

description: In this study, an attempt is made to search for the conditions of implementing the conservation of energy principle model into semiotic modes and semiotic actions. The further purpose is to describe how mechanical work can be represented avoiding the ambiguities concerning the definition of system(s) and the conceptual blending between transfer and transformation of energy. It was shown that both in diagrams and semiotic actions, the separation of the systems and the description of the transfer of energy have to be translated into the successive semiotic units of the ‘no contact between the systems’, the ‘contact of the systems’ and the ‘displacement of the system which receives the energy.

Subjects: Expert teacher, task, difficulty, prediction, technical drawing

description: This article aims at analyzing professional teachers’ expertise by listening to their predictions of difficulties of the tasks assigned to pupils. To achieve this result, we surveyed ten skilled technology teachers. We questioned them about the various levels of difficulties in technical drawing exercises. Scanning the results helped us determine the elements and the characteristics of the tasks assigned to pupils. As well as the reasons behind choosing those type of activities and considering them as a determiner of the level of difficulty. This characterization of prescribed spots regarding difficulty level will enable us in the future to establish a database that will allow us to design training protocol for the novice technology teachers.

European Echoes: Jazz Experimentalism in Germany, 1950-1975

description: "European Echoes: Jazz Experimentalism in Germany, 1950-1975" is a historical and interpretive study of jazz and improvised music in West and East Germany. "European Echoes" illuminates an important period in German jazz whose beginnings are commonly associated with the notion of Die Emanzipation ("The Emancipation"). Standard narratives of this period have portrayed Die Emanzipation as a process in which mid-1960s European jazz musicians came into their own by severing ties of influence to their African American musical forebears. I complicate this framing by arguing that engagement with black musical methods, concepts, and practices remained significant to the early years of German jazz experimentalism. Through a combination of oral histories, press reception, sound recordings, and archival research, I elucidate how local transpositions and adaptations of black musical methods, concepts, and practices in post-war Germany helped to create a prime site for contesting definitions of cultural, national, and ethnic identities across Europe. Using a case study approach, I focus on the lives and works of five of the foremost German jazz experimentalists: multi-reedist Peter Brötzmann, trumpeter and composer Manfred Schoof, pianist and composer Alexander von Schlippenbach, multi-reedist Ernst-Ludwig Petrowsky, and pianist Ulrich Gumpert. Furthermore, I discuss new music composer Bernd Alois Zimmermann's sustained engagement with African American musical forms in addition to the significance of both Schoof's and Schlippenbach's studies and various collaborations with him. The elucidation of the German jazz experimentalism movement is situated within the larger context of ther Cold War's competing West German capitalist and East German state socialist political systems and shows how music became a form of international politics and cultural diplomacy.

Subjects: Biological evolution, randomness, pupils’ conceptions, discussion with philosophic aim

description: The biological theory of evolution is fundamental knowledge for understanding modern biology. It is also a complex object of teaching regarding the nature of the knowledge at stake and pupils’ conceptions. Some pupils exclude the idea of randomness. This could constitute an obstacle toward an evolutionary thought. In this paper, we studied 10 to 12 years old pupils' capacity to speak about a complex subject, randomness. We introduced a qualitative data collection to identify the ideas of 2 groups of pupil on the randomness (K5 and K7), and their evolution during a collective discussion with philosophic aim. The study shows that the DVP allows to collect a large number of ideas of the pupils. The pupils propose different meanings of the randomness. However, the majority doesn’t seem to take into account the idea of contingency, and yet an essential idea to understand the mechanisms of evolution. This research wants to explore the correlation between pupils’ conceptions of biological evolution and their ideas of randomness.

description: The excitation by a high frequency field of multi--level quantum systems with a slowly varying density of states is investigated. A general approach to study such systems is presented. The Floquet eigenstates are characterized on several energy scales. On a small scale, sharp universal quasi--resonances are found, whose shape is independent of the field parameters and the details of the system. On a larger scale an effective tight--binding equation is constructed for the amplitudes of these quasi--resonances. This equation is non--universal; two classes of examples are discussed in detail.

description: As a reliable alternative to animal testing in cardiovascular research, it is crucial to improve differentiation of immortalized cell lines. In this study, we focused on optimizing the differentiation efficiency of the H9c2 cell line into cardiomyocytes using a high-throughput, automated image processing approach. While previous studies used protocols involving retinoic acid to enhance cardiac differentiation, we applied a simplified medium composition that results in higher differentiation rates. Along that line, we differentiated H9c2 cells into cardiomyocytes, which not only showed sarcomere-characteristic striation but also periodic intracellular calcium signaling for the first time. As a second step, we examined the potential application of polyacrylamide hydrogels ( E=12kPa) with defined fibronectin coating densities. The optimum fibronectin density of 2.6 μg/cm 2 found for single cells was investigated to further improve the differentiation efficiency. However, the differentiation and proliferation dynamics dominate the adhesion forces between the cells and the hydrogel, and thus, result in premature clustering and detachment. In conclusion, we identified an optimized differentiation protocol and provided a basis for the further investigation necessary to potentially use hydrogels as natural cell environment, aiming to raise the differentiation efficiency even more.

title: Impact and key drivers of pay-what-you-want pricing in the food service industry
Creators: name: Cramer, Friederike
Year: 2025

description: Ziel der Arbeit ist es herauszufinden, warum sich Menschen für ein Pay-what-you-want-Restaurant entscheiden – ein Restaurant, in dem sie selbst festlegen können, wie viel sie zahlen möchten, sogar gar nichts - und welche Aspekte diese Entscheidung beeinflussen. Auf Basis einer Literaturrecherche wurde ein Discrete-Choice-Experiment (DCE) mit 269 Teilnehmern durchgeführt, das in einen Online-Fragebogen eingebettet war. In der Studie wurden Random-Effects-Modelle und gemischte Logit-Modelle verwendet, um die Präferenzen der Verbraucher und die Heterogenität der Entscheidungsfindung zu untersuchen. Die Preisautonomie erwies sich dabei als Hauptmotivator, der den Konsumenten in ein solches Restaurant treibt. Sozialer Druck wirkt sich zwar auf die Wahrnehmung aus, hat aber nur begrenzten Einfluss auf die Entscheidung. Anreize, wie die Unterstützung wohltätiger Zwecke, lösten gemischte Reaktionen aus, die einige motivierten, während sie andere abschreckten. Das Zusammenspiel dieser Faktoren verdeutlicht, wie wichtig maßgeschneiderte Strategien in PWYW-Modellen sind. Die Ergebnisse können Unternehmen helfen, PWYW-Modelle durch ein Gleichgewicht von Autonomie, sozialer Verantwortung und Diskretion attraktiver zu gestalten. Die kleine Stichprobe und begrenzten DCE-Attribute der Studie begrenzen die Verallgemeinerbarkeit. Zukünftige Forschung sollte größere Stichproben, verschiedene Kontexte und segmentierte Verbraucher einbeziehen.
description: This thesis aims to identify what influences consumers to opt for a Pay-what-you-want restaurant, where consumers have the freedom to pay any amount, they wish including zero, and to determine which factors influence this decision. A discrete choice experiment (DCE) embedded in an online questionnaire, alongside a literature review, was conducted with 269 participants. The study utilized Random Effects and Mixed Logit Models to examine consumer preferences and heterogeneity in decision-making. Pricing autonomy emerged as a key motivator, enabling consumers to align payments with personal satisfaction and fairness. While social pressure affects perceptions, it has limited influence on real-time decisions. Ethical incentives, such as supporting social causes, elicited mixed reactions, motivating some while deterring others. The interplay between these factors highlights the importance of tailored strategies in PWYW models. These findings help businesses optimize PWYW models by balancing autonomy, social responsibility, and discretion for wider appeal. The study's small, non-representative sample and limited DCE attributes constrain generalizability. Future research should use diverse contexts, larger samples, and segment consumers to refine insights.

description: Dictionary learning methods can be split into: i) class specific dictionary learning ii) class shared dictionary learning. The difference between the two categories is how to use discriminative information. With the first category, samples of different classes are mapped into different subspaces, which leads to some redundancy with the class specific base vectors. While for the second category, the samples in each specific class can not be described accurately. In this paper, we first propose a novel class shared dictionary learning method named label embedded dictionary learning (LEDL). It is the improvement based on LCKSVD, which is easier to find out the optimal solution. Then we propose a novel framework named cascaded dictionary learning framework (CDLF) to combine the specific dictionary learning with shared dictionary learning to describe the feature to boost the performance of classification sufficiently. Extensive experimental results on six benchmark datasets illustrate that our methods are capable of achieving superior performance compared to several state-of-art classification algorithms.

description: A N=4 supersymmetric matrix KP hierarchy is proposed and a wide class of its reductions which are characterized by a finite number of fields are described. This class includes the one-dimensional reduction of the two-dimensional N=(2|2) superconformal Toda lattice hierarchy possessing the N=4 supersymmetry -- the N=4 Toda chain hierarchy -- which may be relevant in the construction of supersymmetric matrix models. The Lax pair representations of the bosonic and fermionic flows, corresponding local and nonlocal Hamiltonians, finite and infinite discrete symmetries, the first two Hamiltonian structures and the recursion operator connecting all evolution equations and the Hamiltonian structures of the N=4 Toda chain hierarchy are constructed in explicit form. Its secondary reduction to the N=2 supersymmetric alpha=-2 KdV hierarchy is discussed.

description: This study introduces a novel language-guided diffusion-based learning framework, DexTOG, aimed at advancing the field of task-oriented grasping (TOG) with dexterous hands. Unlike existing methods that mainly focus on 2-finger grippers, this research addresses the complexities of dexterous manipulation, where the system must identify non-unique optimal grasp poses under specific task constraints, cater to multiple valid grasps, and search in a high degree-of-freedom configuration space in grasp planning. The proposed DexTOG includes a diffusion-based grasp pose generation model, DexDiffu, and a data engine to support the DexDiffu. By leveraging DexTOG, we also proposed a new dataset, DexTOG-80K, which was developed using a shadow robot hand to perform various tasks on 80 objects from 5 categories, showcasing the dexterity and multi-tasking capabilities of the robotic hand. This research not only presents a significant leap in dexterous TOG but also provides a comprehensive dataset and simulation validation, setting a new benchmark in robotic manipulation research.

description: In general relativity, the interaction between a black hole and the fields around it (a process known as backreaction) proceeds via the evolution of the black holes mass and angular momentum. Analogue models of gravity, particularly fluid mechanical analogues, have been very successful in mimicking the propagation of fields, and the effects they experience, around black holes. However, hydrodynamic black holes are externally driven systems whose effective mass and angular momentum are set by experimental parameters, and as such no significant internal backreaction processes are expected to take place. We show, using a rotating draining vortex flow, that a fluid system of finite size exhibits a memory that keeps track of scattering processes in the system. This memory is encoded in the total mass of the system and hence, the backreaction arises as a significant global change in the background parameters, as opposed to a small local correction. More importantly, this backreaction is encapsulated by a dynamical metric, raising the possibility of studying wave-background interaction around evolving black hole spacetimes.

description: Phase space structures such as dividing surfaces, normally hyperbolic invariant manifolds, their stable and unstable manifolds have been an integral part of computing quantitative results such as transition fraction, stability erosion in multi-stable mechanical systems, and reaction rates in chemical reaction dynamics. Thus, methods that can reveal their geometry in high dimensional phase space (4 or more dimensions) need to be benchmarked by comparing with known results. In this study, we assess the capability of one such method called Lagrangian descriptor for revealing the types of high dimensional phase space structures associated with index-1 saddle in Hamiltonian systems. The Lagrangian descriptor based approach is applied to two and three degree-of-freedom quadratic Hamiltonian systems where the high dimensional phase space structures are known, that is as closed-form analytical expressions. This leads to a direct comparison of features in the Lagrangian descriptor plots and the phase space structures' intersection with an isoenergetic two-dimensional surface and hence provides a validation of the approach.

description: This communication relates to a teaching sequence designed to help college students to overcome their difficulties of understanding of the physical formulas caused by the conventionality depended of the choice of the symbolism of the physical magnitudes. Despite the dynamic that has characterized its realization, the results of the assessment of the sequence shows that more than half of the students maintained their misconception relating to the existence of an exclusive, official and definitive symbol for each physical magnitude. It seems that the symbolization practices of these magnitudes exercised in classes has been an obstacle to the hoped change. Therefore, the training of the college teachers on the confusion of the symbolism of physical magnitudes can be an appropriate didactical strategy to allow students to remedy the difficulties raised.

description: The experimental design and schematic diagram. Six experiments were conducted in our study. The schematic diagram showed the potential mechanism of BMSCs mediated anti-inflammatory effects on EBI after SAH. Briefly, Notch1 receptors are expressed on microglial cells. Following SAH ictus, Notch1 is activated by proteolytic cleavage, thus releasing NICD into the cytoplasm, which in turn enhances NF-ÎşB activation. In addition, NICD can translocate to the nucleus and combine with RBP-JÎş to generate co-activator complex to promote the transcription of NF-ÎşB and augment the inflammatory response. Botch efficiently antagonized the proteolytic cleavage and activation of the Notch1 receptor. BMSCs treatment upregulated Botch in brain tissue and alleviated the Notch1-driven microglia-mediated inflammatory response. (PDF 88 kb)

description: The purpose of this study is to develop the production method of CO2 hydrate-slurry. In this paper, the production process of CO2 hydrates with pure water dissolved antifreeze proteins (AFPs) is discussed. CO2 hydrate-slurry can be transported from a production place to storage one with a small pressure loss. The AFPs have made the hydrate particles be small and well disperse. It is revealed that the Type III AFPs are effective for the inhibition of structure I hydrate production. By the present experiments, the induction time for the hydrate production increases, and moreover the formation rate of the hydrate and the increasing rate of an agitator torque decrease.

description: This paper addresses the issue of the external aspects of the didactic transposition of dietetics in two countries, France and Morocco. Our aim is to evaluate the continuity between social practices of reference and dietitian training between these two countries. To achieve this, we conduct interviews with four recognized dieticians (two in France and two in Morocco) and we collect institutional documents of the three investigated dietician schools (BTS and DUT in France, and Diplôme d’Etat in Morocco). In particular, we model the social practices of reference as epistemic games. The comparison of these epistemic games with the prescriptions of the three investigated schools allows us to characterize the articulation between training requirements and the reference social practices.

description: We have discovered analytical expressions for the probability density function (PDF) of photons that are multiply scattered in relativistic flows, under the assumption of isotropic and inelastic scattering. These expressions characterize the collective dynamics of these photons, ranging from free-streaming to diffusion regions. The PDF, defined within the light cone to ensure the preservation of causality, is expressed in a three-dimensional space at a constant time surface. This expression is achieved by summing the PDFs of photons that have been scattered $n$ times within four-dimensional spacetime. We have confirmed that this formulation accurately reproduces the results of relativistic Monte Carlo simulations.We found that the PDF in three-dimensional space at a constant time surface can be represented in a separable variable form. We demonstrate the behavior of the PDF in the laboratory frame across a wide range of Lorentz factors for the relativistic flow. When the Lorentz factor of the fluid is low, the behavior of scattered photons evolves sequentially from free propagation to diffusion, and then to dynamic diffusion, where the mean effective velocity of the photons equates to that of the fluid. On the other hand, when the Lorentz factor is large, the behavior evolves from anisotropic ballistic motion, characterized by a mean effective velocity approaching the speed of light, to dynamic diffusion.

description: We obtain the following version of Lidskii theorem. Let L, M, N be p-dimensional subspaces in R^n. Let ψ_j be the angles between L and M, let ϕ_j be the angles between M and N, and let θ_j be the angles between L and N. Consider the orbit of the vector ψwith respect to permutations of coordinates and inversions of axises. Let Z be the convex hull of this orbit. Then θis an element of the polyhedron ϕ+ Z. We discuss similar theorems for other symmetric spaces. We obtain formula for geodesic distance for any invariant Finsler metrics on a classical Riemannian symmetric space.

description: In this paper, a new version of very large scale integration (VLSI) layouts compaction problem is considered.
Bar visibility graph (BVG) is a simple geometric model for VLSI chip design and layout problems. In all previous works, vertical bars or other chip components in the plane model gates, as well as edges, are modeled by horizontal visibilities between bars. In this study, for a given set of vertical bars, the edges can be modeled with orthogonal paths known as staircases. Therefore, we consider a new version of bar visibility graphs (BsVG). We then present an algorithm to solve the s-visibility problem of vertical segments, which can be implemented on a VLSI chip. Our algorithm determines all the pairs of segments that are s-visible from each other.

description: Kiruna-type or IOA deposits are characterized by magnetite-apatite-actinolite associations and may contain considerable amounts of rare earth elements (REEs) that can be exploited as by-products. REEs in the Kiruna-type deposit, heterogeneously distributed, are mainly hosted in phosphates (e.g. apatite). Published data of apatite, together with other evidence, can be used to decipher the source, enrichment mechanism, and post-ore modification of REEs in the Kiruna-type deposits. Sr isotopes and melt inclusions compositions of apatite, together with other evidence, support a mantle + evaporite affinity for the ore-forming materials of many IOA deposits. Ore-forming materials of different IOA deposits may originate from primitive, depleted, or enriched mantle sources respectively. This suggests that magmatic-hydrothermal evolutions, rather than REE-enriched mantle source, are probably more important for REE enrichment in Kiruna-type deposits. Increasing evidence supports an ortho-magmatic origin of IOA deposits, yet detailed forming model is still in debate. From the perspective of models forming Fe-P-rich melts, we tentatively test the REE enrichment mechanism of IOA deposit. Sulphate-rich, Fe-P-bearing melts have been observed in the Iron Springs, Buena Vista, and El Laco IOA deposits. These melts may extract REEs from silicate magmas and thus contribute to REE enrichment. Compiled experimental data show that Fe-P melts would incorporate more REEs than the silicate-rich melts during magma Fe-Si immiscibility. As a result, magma Fe-Si immiscibility potentially occurring in IOA deposits may also assist in the enrichment of REEs. Hydrothermal events in the Kiruna-type deposits could result in formation of monazite and xenotime, which is beneficial for industrial recovery of REE. Finally, the existence of various magmatic-hydrothermal Fe-REE assemblages (e.g. IOA deposit, Bayan Obo deposit) implies that co-enrichment of iron and REEs can occur during various magmatic-hydrothermal processes.

description: A priori, a posteriori, and mixed type upper bounds for the absolute change in Ritz values of self-adjoint matrices in terms of submajorization relations are obtained. Some of our results prove recent conjectures by Knyazev, Argentati, and Zhu, which extend several known results for one dimensional subspaces to arbitrary subspaces. In addition, we improve Nakatsukasa's version of the $\tan Θ$ theorem of Davis and Kahan. As a consequence, we obtain new quadratic a posteriori bounds for the absolute change in Ritz values.

description: In the United States, an aging and overburdened urban infrastructure has become a substantial challenge for civil engineers. Among these challenges, systems for stormwater management are of significant concern, considering their direct impact on environmental quality, local ecosystems, and the hydrologic cycle. Given the high costs for rehabilitation of traditional stormwater infrastructure in urban settings, low impact, or "green" development strategies have become critical components in plans for meeting future stormwater management goals. In particular, New York City (NYC) has pledged $1.5 billion over the next 20 years to improve environmental quality through the mitigation of urban runoff, where utilization of green infrastructure is a primary goal. Cost effective implementation of this, and similar plans around the world, requires comprehensive understanding of green infrastructure functionality. In response, this dissertation investigates the stormwater management potential of full-scale green roofs in NYC through lenses of observation, modeling, and design.
      Exploration of this topic has resulted in new findings which quantify the: influence of dominant environmental and physical properties on green roof hydrologic performance, envelope of potential green roof rainfall capture in NYC, and predictive efficiency of contemporary hydrologic models for green roof assessment. This work has also lead to new methods for the: extension of green roof observations to account for the influence of rainfall distribution, parameterization of green roof hydrologic processes, and prediction of full-scale green roof rainfall capture in advance of construction. Going forward, these findings and methods are useful for informing green roof policy, planning, and design; where, in particular, this information supports the development of green roof policies that correlate to specific stormwater management goals. In summation, the characterization of green roof stormwater management in NYC, as presented in this dissertation, has contributed to the understanding of, among other topics, green roof design, urban stormwater management, hydrologic modeling, and the broad interdisciplinary field of urban ecological systems.
