We present a new approach to the problem of optimal control of solar sails for low-thrust trajectory optimization. The objective was to find the required control torque magnitudes in order to steer a solar sail in interplanetary space. A new steering strategy, controlling the solar sail with generic torques applied about the spacecraft body axes, is integrated into the existing low-thrust trajectory optimization software InTrance. This software combines artificial neural networks and evolutionary algorithms to find steering strategies close to the global optimum without an initial guess. Furthermore, we implement a three rotational degree-of-freedom rigid-body attitude dynamics model to represent the solar sail in space. Two interplanetary transfers to Mars and Neptune are chosen to represent typical future solar sail mission scenarios. The results found with the new steering strategy are compared to the existing reference trajectories without attitude dynamics. The resulting control torques required to accomplish the missions are investigated, as they pose the primary requirements to a real on-board attitude control system.
Künstlerische Einlassungen auf den öffentlichen Raum folgten lange Zeit dem Prinzip des subkulturellen Widerstands. Nur in dem strategischen, invasiven Akt der Intervention sah man noch die Möglichkeit einer weitgreifenden Kritik am kulturellen System. Begriffe wie Cultural Hacking, Guerilla Marketing, Adbusting, Konsumguerilla oder parasitäre Strategien prägten eine rebellische Auffassung der künstlerischen Einmischung. Gleichzeitig konnten diese Haltungen aufgrund ihres rebellischen Chics mühelos von dem, was sie kritisierten, aufgenommen und vereinnahmt werden. Künstlerisches Handeln verharrt jedoch nicht in der Pose des Widerständigen, sondern arbeitet kontinuierlich an der Problematisierung und Gestaltung der öffentlichen Wahrnehmung. Viele Interventionen der Gegenwartskunst weisen unterschiedliche Grade der Ästhetisierung, der Partizipation und der Kooperation in der Auseinandersetzung mit dem öffentlichen Raum auf. Das wache Agieren im urbanen Kontext, die Irritation von Erwartungshaltungen, Fake und Desillusionierungsarbeit verstehen sich als künstlerische Arbeit an der Sensibilisierung der Wahrnehmung.
Pandemische Momente

The existence of several mobile operating systems, such as Android and iOS, is a challenge for developers because the individual platforms are not compatible with each other and require separate app developments. For this reason, cross-platform approaches have become popular but lack in cloning the native behavior of the different operating systems. Out of the plenty cross-platform approaches, the progressive web app (PWA) approach is perceived as promising but needs further investigation. Therefore, the paper at hand aims at investigating whether PWAs are a suitable alternative for native apps by developing a PWA clone of an existing app. Two surveys are conducted in which potential users test and evaluate the PWA prototype with regard to its usability. The survey results indicate that PWAs have great potential, but cannot be treated as a general alternative to native apps. For guiding developers when and how to use PWAs, four design guidelines for the development of PWA-based apps are derived based on the results.
Vitamin D plays an essential role in calcium and inorganic phosphate (Pi) homeostasis, maintaining their optimal levels to assure adequate bone mineralization. Vitamin D, as calcitriol (1,25(OH)2D), not only increases intestinal calcium and phosphate absorption but also facilitates their renal reabsorption, leading to elevated serum calcium and phosphate levels. The interaction of 1,25(OH)2D with its receptor (VDR) increases the efficiency of intestinal absorption of calcium to 30–40% and phosphate to nearly 80%. Serum phosphate levels can also influence 1,25 (OH)2D and fibroblast growth factor 23 (FGF23) levels, i.e., higher phosphate concentrations suppress vitamin D activation and stimulate parathyroid hormone (PTH) release, while a high FGF23 serum level leads to reduced vitamin D synthesis. In the vitamin D-deficient state, the intestinal calcium absorption decreases and the secretion of PTH increases, which in turn causes the stimulation of 1,25(OH)2D production, resulting in excessive urinary phosphate loss. Maintenance of phosphate homeostasis is essential as hyperphosphatemia is a risk factor of cardiovascular calcification, chronic kidney diseases (CKD), and premature aging, while hypophosphatemia is usually associated with rickets and osteomalacia. This chapter elaborates on the possible interactions between vitamin D and phosphate in health and disease.
