description: Hydropower provides a source of reliable and inexpensive energy, producing approximately 20% of the global energy supply, though it comes at a cost to riverine ecosystems. To maximize revenues, major hydropower facilities store and release water with respect to short-term changes in energy price, causing significant sub-daily flow regime alterations that impact downstream ecological communities. In the United States, the Federal Energy Regulatory Commission (FERC) is responsible for hydropower regulation and this is administered, in part, during periodic relicensing of existing facilities. The process of relicensing provides the opportunity to evaluate the goals and concerns of interested parties and evaluate potential operational changes in licensure which may support these goals, often including constraints aimed at supporting ecological improvements. This paper explores potential changes in reservoir operating rules for a series of five peaking hydropower facilities on the Connecticut River undergoing FERC relicensing that should complete in 2019. This paper evaluates the trade-offs between two primary goals: maximizing revenues from hydroelectric power generation and returning the river to a more natural flow regime. These trade-offs are assessed using the Connecticut River Hydropower Operations Program (CHOP), a linear programming (LP) optimization model applied at an hourly time-step to capture the sub-daily effects to the flow regime. The model objective function is formulated to maximize hydropower revenues with respect to historical regional energy price data and is demonstrated to accurately mimic hydropeaking operating conditions and match historical power generating rates. A case study compares modeled hydropower operating conditions between current hydropeaking operations and a strict run-of-river condition, where dam inflows must be directly released as outflows at all times. Analysis suggests that the run-of-river condition would result in a total economic loss of 7-9% of average annual revenues at the four mainstem facilities and as much as 17% at the larger, pumped-storage facility. However, an exploration of operating revenue losses at the pumped-storage facility suggests that there is potential for reoperations within the run-of-river operating condition to substantially reduce these losses. The run-of-river operation is demonstrated to improve the Connecticut River’s flow regime on the sub-daily time scale, with significant reductions in rates of change in flows to levels that approach those observed at a nearby unaltered location. The modeled improvements to the flow regime demonstrate the merit of this run-of-river condition as a potential reoperation for the hydropower system.

description: Today, the heterogeneity of NLP tools in relation to existing methods and the constantly growing availability of models confronts various disciplines with major challenges in the daily handling of natural language processing. These are golden times for all scientific fields, as different models can be applied to the respective corpora; although in the short term this leads to non-trivial challenges in terms of analysis time, heterogeneity of (corpora) formats, processing input and output formats as well as analyzeability. These many construction phases show the need for a reliable working tool that can be used without intensive training, which is available in the form of Docker Unified UIMA Interface (DUUI). DUUI is designed as a platform-independent annotation framework for the horizontal and vertical distribution of heterogeneous NLP processes towards microservice-oriented homogenization using web services for a unified processing and reuse of unstructured data.

description: Objective. Exploring neural activity behind synchronization and time locking in brain circuits is one of the most important tasks in neuroscience. Our goal was to design and characterize a microelectrode array (MEA) system specifically for obtaining in vivo extracellular recordings from three deep-brain areas of freely moving rats, simultaneously. The target areas, the deep mesencephalic reticular-, pedunculopontine tegmental- and pontine reticular nuclei are related to the regulation of sleep-wake cycles. Approach. The three targeted nuclei are collinear, therefore a single-shank MEA was designed in order to contact them. The silicon-based device was equipped with 3*4 recording sites, located according to the geometry of the brain regions. Furthermore, a microdrive was developed to allow fine actuation and post-implantation relocation of the probe. The probe was attached to a rigid printed circuit board, which was fastened to the microdrive. A flexible cable was designed in order to provide not only electronic connection between the probe and the amplifier system, but sufficient freedom for the movements of the probe as well. Main results. The microdrive was stable enough to allow precise electrode targeting into the tissue via a single track. The microelectrodes on the probe were suitable for recording neural activity from the three targeted brainstem areas. Significance. The system offers a robust solution to provide long-term interface between an array of precisely defined microelectrodes and deep-brain areas of a behaving rodent. The microdrive allowed us to fine-tune the probe location and easily scan through the regions of interest.

description: The high TC ferromagnetism in (Ga,Mn)N were observed and almost all results are approximately similar to the experimental results in (Ga,Mn)As except the value of TC. Though all standard experiments on magnetism clearly support the results, the value is unexpectedly high. This work present and discuss the possibility of high TC ferromagnetism, after brief review of the experimental results. The key speculation to Bosonization method in three dimensions is resembled with the problems in Anderson localization.

description: Entlang von Textpassagen aus Ludwig Hubers Werk, die an dem zu seinen Ehren veranstalteten Gedenksymposion am 7. Dezember 2019 im Oberstufen-Kolleg diskutiert wurden, dokumentiert und reflektiert dieser Beitrag das breite Spektrum seines Wirkens. Die Textauswahl folgt dabei nicht dem Anspruch einer Repräsentativität oder einer disziplinär legitimierten Fachsystematik, sondern in Anlehnung an Ludwig Hubers Bildungsprogramm zur Auseinandersetzung mit relevanten Kulturgegenständen, also dem Anspruch subjektiver Relevanzsetzungen. Kommentiert und diskutiert werden demnach Textpassagen Ludwig Hubers, die für das Denken der Autor*innen über gymnasiale Oberstufe, Hochschule und Forschung subjektiv bedeutsam geworden sind. Die ebenfalls dokumentierten Diskussionen aus den Lektüregruppen mit den Teilnehmer*innen des Gedenksymposions belegen die nachhaltige Aktualität der Gedanken und Argumente Ludwig Hubers. Along the text passages from Ludwig Huber’s work, which were discussed at the commemorative symposium on December 7, 2019, in the Oberstufen-Kolleg, this contribution documents and reflects the broad spectrum of his work. The selection of texts does not follow the claim of representativeness or a disciplinarily legitimized system of subject matter, but rather, in accordance with Ludwig Huber’s educational program for the confrontation with relevant cultural objects, i.e., the claim of subjective relevance. Accordingly, Ludwig Huber’s text passages, which have become subjectively significant for the authors’ thinking about upper secondary school, university, and research, will be commented on and discussed. The discussions documented from the reading groups with the participants of the commemorative symposium prove the lasting topicality of Ludwig Huber’s thoughts and arguments.

description: In this paper, the performance of single-tone Radio over Fiber (RoF) system has been analyzed by employing different duobinary modulation formats. This single-tone RoF system has been modeled and analyzed using OptiSystem (14.0) software. To evaluate the transmission performance of RoF system, various performance metrics such as Q-factor, BER, and Eye Height are considered. Simulation results indicate that duobinary Hyperbolic-Secant pulse generator format with Single Drive Mach-Zehnder modulator provides better Q-factor and minimum BER as compared to existing modulation format in RoF system.

description: We show the factorization of correlation functions of tachyon operators in 2D string theory using the discretized approach of Moore. Our demonstration of the factorization is more general than that of the paper of Sakai and Tanii. We obtain the rules for the factorization of tachyon amplitudes. Our results can be understood in terms of the operator product expansion of tachyon operators. We also give a systematic way of computing correlation functions of tachyon operators and succeed in summarizing the results of the computation in compact form for some simple cases. We confirm that these tachyon amplitudes indeed satisfy our factorization rule.

description: A key objective of the ESA Gaia satellite is the realization of a quasi-inertial reference frame at visual wavelengths by means of global astrometric techniques. This requires an accurate mathematical and numerical modeling of relativistic light propagation, as well as double-blind-like procedures for the internal validation of the results, before they are released to the scientific community at large. Aim of this work is to specialize the Time Transfer Functions (TTF) formalism to the case of the Gaia observer and prove its applicability to the task of Global Sphere Reconstruction (GSR), in anticipation of its inclusion in the GSR system, already featuring the suite of RAMOD models, as an additional semi-external validation of the forthcoming Gaia baseline astrometric solutions. We extend the current GSR framework and software infrastructure (GSR2) to include TTF relativistic observation equations compatible with Gaia's operations. We use simulated data generated by the Gaia Data Reduction and Analysis Consortium (DPAC) to obtain different least-squares estimations of the full stellar spheres and gauge results. These are compared to analogous solutions obtained with the current RAMOD model in GSR2 and to the catalog generated with GREM, the model baselined for Gaia and used to generate the DPAC synthetic data. Linearized least-squares TTF solutions are based on spheres of about 132,000 primary stars uniformly distributed on the sky and simulated observations spanning the entire 5-yr range of Gaia's nominal operational lifetime. The statistical properties of the results compare well with those of GREM. Finally, comparisons to RAMOD@GSR2 solutions confirmed the known lower accuracy of that model and allowed us to establish firm limits on the quality of the linearization point outside of which an iteration for non-linearity is required for its proper convergence.

description: We report the occurrence of the zero-bias conductance peak (ZBCP) in an InAs nanowire coupled to PbIn superconductors with varying temperature, bias voltage, and magnetic field. The ZBCP is suppressed with increasing temperature and bias voltage above the Thouless energy of the nanowire. Applying a magnetic field also diminishes the ZBCP when the resultant magnetic flux reaches the magnetic flux quantum h/2e. Our observations are consistent with theoretical expectations of reflectionless tunneling, in which the phase coherence between an electron and its Andreev-reflected hole induces the ZBCP as long as time-reversal symmetry is preserved.

Praxisforschung und Transfer – eine Einführung in den Themenschwerpunkt

description: Im vorliegenden Beitrag wird aufgezeigt, dass die Hoffnungen auf Transfer der Ergebnisse empirischer Bildungsforschung in die pädagogische Praxis sich nicht in dem Maße erfüllen, wie dies vor einigen Jahren noch erwartet wurde. Praxisforschung scheint hier auf den ersten Blick als eine Alter-native, da sie per definitionem praxisnäher ist und damit die Differenz zwischen Forschungslogik und der Eigenlogik der Praxis automatisch überwunden zu sein scheint. Jenseits der forschungsmethodischen Probleme der Generalisierung und nicht umstandslos vorauszusetzender ökologischer Validität erweist es sich allerdings auch für die Praxisforschung als Tatsache, dass Transfer sich nicht von selbst einstellt, sondern als Gegenstand der eigenen Bearbeitung bedarf. In der Einführung werden ausgehend von diesen Überlegungen die unterschiedlichen Zugänge zu dieser Thematik skizziert, wie sie in den Beiträgen dieses Jahrbuchs der Versuchsschule Oberstufen-Kolleg enthalten sind. This article shows that hopes of transferring the results of empirical educational research into pedagogical practice have not been fulfilled so far to that extent as it was expected a few years ago. At first glance, practice research seems to be an alternative, since it is by definition more practice-oriented and thus automatically overcomes the difference between the logic of research logic and the practice’s own logic. Beyond the research-methodological problems of generalization and the not necessarily pre-supposable ecological validity, however, it also turns out to be a fact for practice research that transfer does not take place automatically, but requires its own processing. Based on these considerations, the article outlines the different approaches to this topic as they are presented in the contributions of this yearbook of the experimental school Oberstufen-Kolleg.

Volume-controlled buckling of thin elastic shells: Application to crusts formed on evaporating partially-wetted droplets

description: Motivated by the buckling of glassy crusts formed on evaporating droplets of polymer and colloid solutions, we numerically model the deformation and buckling of spherical elastic caps controlled by varying the volume between the shell and the substrate. This volume constraint mimics the incompressibility of the unevaporated solvent. Discontinuous buckling is found to occur for sufficiently thin and/or large contact angle shells, and robustly takes the form of a single circular region near the boundary that `snaps' to an inverted shape, in contrast to externally pressurised shells. Scaling theory for shallow shells is shown to well approximate the critical buckling volume, the subsequent enlargement of the inverted region and the contact line force.

description: The effects of point defects on the loss of either energies of ballistic electron beams or incident photons are studied by using a many-body theory in a multi-quantum-well system. This includes the defect-induced vertex correction to a bare polarization function of electrons within the ladder approximation as well as the intralayer and interlayer screening of defect-electron interactions are also taken into account in the random-phase approximation. The numerical results of defect effects on both energy-loss and optical-absorption spectra are presented and analyzed for various defect densities, number of quantum wells, and wave vectors. The diffusion-reaction equation is employed for calculating distributions of point defects in a layered structure. For completeness, the production rate for Frenkel-pair defects and their initial concentration are obtained based on atomic-level molecular-dynamics simulations. By combining defect-effect, diffusion-reaction and molecular-dynamics models proposed in this paper with a space-weather forecast model for the first time, it will be possible to enable specific designing for electronic and optoelectronic quantum devices that will be operated in space with radiation-hardening protection, and therefore, will effectively extend the lifetime of these satellite onboard electronic and optoelectronic devices.

description: Wissenschaftspropädeutik gilt neben einer vertieften Allgemeinbildung und Studierfähigkeit als wesentliches Element der Bildung in der Oberstufe. Forschendes Lernen könnte für Schüler*innen eine Möglichkeit darstellen, um im Unterricht eine „Bildung durch Wissenschaft“ zu erfahren. Bisher gibt es nur wenige Untersuchungen, die systematisch die Gelingensbedingungen und das Potenzial von Forschendem Lernen untersuchen, insbesondere, wenn man diesen Befund auf Schüler*innenforschung bezieht oder sogar auf partizipative Schüler*innenforschung im Bereich der Schulentwicklung ausweitet. Im Rahmen des Forschungs- und Entwicklungsprojektes (FEP) „Forschendes Lernen in der Oberstufe“ (FLidO) am Oberstufen-Kolleg erfolgt ein systematischer Ansatz zur Etablierung und Beforschung von Strukturen für Forschendes Lernen allgemein sowie insbesondere von partizipativen Forschungsstrukturen. Im Rahmen dieses Beitrages werden zunächst die Begriffe „Forschendes Lernen“ und „Partizipative Ak-tionsforschung“ theoretisch hergeleitet, der Forschungsstand dargestellt und die Grundkonzeption des Projektes beschrieben. Es werden die Arbeitsdefinition zum Forschenden Lernen im Projekt, die Leitideen für die konkrete Umsetzung des Forschenden Lernens in den verschiedenen Kontexten und exemplarisch zwei der fünf Kontexte, innerhalb derer Forschendes Lernen am Oberstufen-Kolleg Bielefeld implementiert wurde, vorgestellt. In addition to advanced general education and the ability to study, science propaedeutics (‘Wissenschaftspropädeutik’) is an essential element of upper secondary education. Research-based learning could be a way to enable students to pursue their education within the scope of science. So far, there are only a few studies that systematically analyze the prerequisites for success and the potential of research-based learning, especially if one refers to students’ research or even extends it to participatory students’ research in the field of school development. The research and development project “Research-based Learning in Upper Secondary Education” at the Oberstufen-Kolleg follows a systematic approach to set up structures for research-based learning in general, as well as participatory research structures are pursued. In this paper, the terms “research-based learning” and “participatory action research” will be derived theoretically, the state of research on this topic will be presented, and the conceptual framework of the project will be described. The working definition of research-based learning in the project, the guiding ideas for the concrete implementation of research-based learning in the various contexts and two examples of research-based learning implemented at the Oberstufen-Kolleg Bielefeld are presented.

description: Cloud-native applications, characterized by scalability, resilience, and flexibility, adopt microservices architectures to decompose applications into smaller, independently manageable services. Although microservices offer significant benefits, this architectural approach introduces challenges in service-to-service communication, commonly relying on advanced orchestration and communication frameworks such as Kubernetes and Istio, respectively. However, the added complexity imposes substantial overhead by introducing longer packet processing paths. This paper discusses performance bottlenecks arising from service meshes and proposes eZtunnel to address some of the identified challenges. Leveraging extended Berkeley Packet Filter (eBPF) to transparently offload networking traffic, the elongated network path is bypassed, optimizing resource utilization and enhancing application performance. Experiments show that eZtunnel can reduce median latency over 20% and jitter to almost 10%.

description: The relative stability among the multiple spin density wave (MSDW) states in fcc transition metals has been investigated on the basis of a Ginzburg-Landau type of free energy with terms up to the fourth order in magnetic moments. Obtained magnetic phase diagrams in the space of expansion coefficients indicate the possibility of various 3Q MSDW states in fcc transition metals: the commensurate 3Q state, the incommensurate linear 3Q state, and the incommensurate helical 3Q state. It is shown that these 3Q states are always stabilized, when they are compared with the corresponding 2Q and 1Q states, and their magnetic moment amplitudes are the largest among those of the three states. The results are compared with previous results of the ground-state calculations, and possible scenarios to explain the experimental data of fcc-Fe are proposed.

description: Quantum interference is at the heart of what sets the quantum and classical worlds apart. We demonstrate that quantum interference effects involving a many-body working medium is responsible for genuinely non-classical features in the performance of a quantum heat engine. The features with which quantum interference manifests itself in the work output of the engine depends strongly on the extensive nature of the working medium. While identifying the class of work substances that optimize the performance of the engine, our results shed light on the optimal size of such media of quantum workers to maximize the work output and efficiency of quantum energy machines.

description: Increasing amounts of data from varied sources, particularly in the fields of machine learning and graph analytics, are causing storage requirements to grow rapidly. A variety of technologies exist for storing and sharing these data, ranging from parallel file systems used by supercomputers to distributed block storage systems found in clouds. Relatively few comparative measurements exist to inform decisions about which storage systems are best suited for particular tasks. This work provides these measurements for two of the most popular storage technologies: Lustre and Amazon S3. Lustre is an open-source, high performance, parallel file system used by many of the largest supercomputers in the world. Amazon's Simple Storage Service, or S3, is part of the Amazon Web Services offering, and offers a scalable, distributed option to store and retrieve data from anywhere on the Internet. Parallel processing is essential for achieving high performance on modern storage systems. The performance tests used span the gamut of parallel I/O scenarios, ranging from single-client, single-node Amazon S3 and Lustre performance to a large-scale, multi-client test designed to demonstrate the capabilities of a modern storage appliance under heavy load. These results show that, when parallel I/O is used correctly (i.e., many simultaneous read or write processes), full network bandwidth performance is achievable and ranged from 10 gigabits/s over a 10 GigE S3 connection to 0.35 terabits/s using Lustre on a 1200 port 10 GigE switch. These results demonstrate that S3 is well-suited to sharing vast quantities of data over the Internet, while Lustre is well-suited to processing large quantities of data locally.

description: High Energy Particle Physics experiments at the LHC use hybrid silicon detectors, in both pixel and strip geometry, for their inner trackers. These detectors have proven to be very reliable and performant. Nevertheless, there is great interest in the development of depleted CMOS silicon detectors, which could achieve similar performances at lower cost of production and complexity. We present recent developments of this technology in the framework of the ATLAS CMOS demonstrator project. In particular, studies of two active sensors from LFoundry, CCPD_LF and LFCPIX, and the first fully monolithic prototype MONOPIX will be shown.

description: Magnon Bose condensation (BC)in the symmetry breaking magnetic field is a result of unusual form of the Zeeman energy, which has terms linear in the spin-wave operators and terms mixing excitations differ in the Wave-vector of the magnetic structure. The following examples are considered: simple easy-plane tetragonal antiferromagnets (AF), frustrated AF family$R_2Cu O_4$ where $R=Pr,Nd$ etc. and cubic magnets with the Dzyaloshinskii-Moriya interaction ($Mn Si$ etc.). In all cases the BC becomes important when the magnetic field becomes comparable with the spin-wave gap. The theory is illustrated by existing experimental results.

description: Apoptosis is essential for numerous processes, such as development, resistance to infections, and suppression of tumorigenesis. Here, we investigate the influence of the nutrient sensing and longevity-assuring enzyme SIRT6 on the dynamics of apoptosis triggered by serum starvation. Specifically, we characterize the progression of apoptosis in wild type and SIRT6 deficient mouse embryonic fibroblasts using time-lapse flow cytometry and computational modelling based on rate-equations and cell distribution analysis. We find that SIRT6 deficient cells resist apoptosis by delaying its initiation. Interestingly, once apoptosis is initiated, the rate of its progression is higher in SIRT6 null cells compared to identically cultured wild type cells. However, SIRT6 null cells succumb to apoptosis more slowly, not only in response to nutrient deprivation but also in response to other stresses. Our data suggest that SIRT6 plays a role in several distinct steps of apoptosis. Overall, we demonstrate the utility of our computational model to describe stages of apoptosis progression and the integrity of the cellular membrane. Such measurements will be useful in a broad range of biological applications. We describe a computational method to evaluate the progression of apoptosis through different stages. Using this method, we describe how cells devoid of SIRT6 longevity gene respond to apoptosis stimuli, specifically, how they respond to starvation. We find that SIRT6 cells resist apoptosis initiation; however, once initiated, they progress through the apoptosis at a faster rate. These data are first of the kind and suggest that SIRT6 activities might play different roles at different stages of apoptosis. The model that we propose can be used to quantitatively evaluate progression of apoptosis and will be useful in studies of cancer treatments and other areas where apoptosis is involved.
Four Dimensional Gravitational Backgrounds Based on N=4 c=4 Superconformal Systems

description: We propose two new realizations of the N=4, $\hat{c}=4$ superconformal system based on the compact and non-compact versions of parafermionic algebras. The target space interpretation of these systems is given in terms of four-dimensional target spaces with non-trivial metric and topology different from the previously known four-dimensional semi-wormhole realization. The proposed $\hat{c}=4$ systems can be used as a building block to construct perturbatively stable superstring solutions with covariantized target space supersymmetry around non-trivial gravitational and dilaton backgrounds.

Abstract:

Computational chemistry has revolutionized drug discovery, providing robust frameworks for understanding complex molecular interactions and facilitating the rational design of therapeutic compounds. This talk will explore the applications of computational techniques, such as molecular docking, molecular dynamics (MD), and free energy perturbation (FEP) in drug design, as well as the growing role of artificial intelligence (AI) in this field.

Taking advantage of these methods, researchers can explore uncharted territories and, particularly, predict binding affinities, optimize pharmacokinetic profiles, and design molecules with high therapeutic potential.

A key example of this approach is the study of the identification of possible, selective inhibitors of the acetylcholinesterase enzyme (AChE) from Drosophila melanogaster (fruit fly) with higher affinity for this variant compared to the human enzyme, as a less toxic alternative to commercial insecticides. Four ligands, selected through virtual screening, were computationally evaluated for their interactions with three AChE variants: human, Drosophila melanogaster and electric eel, the latter serving as an experimental reference. The methodology combined tools such as docking, molecular dynamics, and free energy perturbation (FEP) calculations to estimate binding free energy values (Δ𝐺_binding) and identify key interactions between the ligands and enzymes. These analyses contribute to the development of more selective and safer inhibitors for potential application as insecticides.
