description: At DLR neural networks, as potential future controller for rocket engines, are studied. A neural networkbased chamber pressure controller for a simplified cold gas thruster is presented and analyzed in simulation and experiment. The goal of the controller is twofold: It can track a trajectory with different changes of setpoints and it allows to set and control a wide variety of steady state chamber pressures. The neural network gets feeding line pressure measurement data as input and calculates valve positions as output values. The training phase of the controller is done with a reinforcement learning algorithm in an EcosimPro/ESPSS simulation, that is validated with data from the corresponding experimental set up. To increase the robustness and to allow a transfer from the simulation directly to the test facility domain randomization is applied. The controller is evaluated in simulations and experiment. It was found that -in the range of physically possible operation points -the controller achieves a constantly high reward which corresponds to a low error and a good control performance. In the simulation the controller was able to adjust all required set points with a steady state error of less than 0.1 bar while retaining a small overshoot and an optimal settling time. It is found that the controller is also able to regulate all desired set points in the real experiment. A reference trajectory with different steps, linear and sinus changes in target pressure is tested in simulation and experiment. The controller was in both cases able to successfully follow the given trajectory.

description: The charmed meson pair $(\frac{3}{2})^+$ and anti-$(\frac{1}{2})^-$, i.e. $D_1(2420)\bar D+c.c.$, $D_1(2420)\bar D^*+c.c.$, $D_2(2460)\bar D^*+c.c.$, can couple to states with vector quantum number $J^{PC}=1^{--}$ and exotic quantum number $J^{PC}=1^{-+}$ in a relative $S$ wave. Near threshold, the charmed meson pair may form hadronic molecules due to the strong $S$-wave coupling, and the mysterious vector state $Y(4260)$ could be such a state of the $D_1(2420)\bar D+c.c.$ molecule. This implies the possible existence of its exotic partner made of the same charmed mesons but with $J^{PC}=1^{-+}$. We evaluate the production rate of such exotic hadronic molecules and propose a direct experimental search for them in $e^+e^-$ annihilation. The confirmation of such exotic states in experiment will shed light on the spectrum in the heavy quark sector.

description: An original optical tweezers using one or two chemically etched fiber nano-tips is developed. We demonstrate optical trapping of 1 micrometer polystyrene spheres at optical powers down to 2 mW. Harmonic trap potentials were found in the case of dual fiber tweezers by analyzing the trapped particle position fluctuations. The trap stiffness was deduced using three different models. Consistent values of up to 1 fN/nm were found. The stiffness linearly decreases with decreasing light intensity and increasing fiber tip-to-tip distance.

Formation of disk galaxies in preheated media: a preventative feedback model

description: We introduce a semi-analytic galaxy formation model implementing a self-consistent treatment for the hot halo gas configuration and the assembly of central disks. Using the model, we explore a preventative feedback model, in which the circum-halo medium is assumed to be preheated up to a certain entropy level by early starbursts or other processes, and compare it with an ejective feedback model, in which baryons are first accreted into dark matter halos and subsequently ejected out by feedback. The model demonstrates that when the medium is preheated to an entropy comparable to the halo virial entropy the baryon accretion can be largely reduced and delayed. In addition, the preheated medium can establish an extended low density gaseous halo when it accretes into the dark matter halos, and result in a specific angular momentum of the cooling gas large enough to form central disks as extended as those observed. Combined with simulated halo assembly histories, the preventative feedback model can reproduce remarkably well a number of observational scaling relations. These include the cold baryon (stellar plus cold gas) mass fraction-halo mass relations, star formation histories, disk size-stellar mass relation and its evolution, and the number density of low-mass galaxies as a function of redshift. In contrast, the conventional ejective feedback model fails to reproduce these observational trends. Using the model, we demonstrate that the properties of disk galaxies are closely tied to the thermal state of hot halo gas and even possibly the circum-halo medium, which suggests that observational data for the disk properties and circum-galactic hot/warm medium may jointly provide interesting constraints for galaxy formation models.

description: For future manned and unmanned space missions, landing systems are required, which are able to initiate and carry out soft autonomous landings on extraterrestrial celestial bodies. Development of rapid and robust guidance and control (GNC) systems as well as efficient, controllable and safe thrusters meeting a high level of autonomy and safety is crucial for successful lander missions. To meet those requirements, both component level view such as physico-chemical behavior of the propellants and the transients of the propulsion system itself as well as the system level view of the behavior of the holistic system are of utmost interest. To enable extensive testing and demonstration of new GNC methods and rocket engines, DLR Lampoldshausen has extended its research fields to develop a modular lander platform and a test bench with variable degrees of freedom. The aim is to combine extensive testing of GNC algorithms with sustainable propellant technology.

TWO-POINT BOUNDARY VALUE PROBLEM (TPBVP)

description: This paper studies the design process of translunar injection (LTI) trajectories using phasing loops given initial and terminal conditions. Starting from the two-body problem (2BP) assumption, a highly perturbed restricted three-body problem (ER3BP) environment is eventually introduced in the investigation of the algorithms. Exploring the moon becomes a worldwide space mission recently, owing to the potential of human inhabitant. The Taiwan Space Agency (TASA), formerly known as NSPO, initiated a preliminary study on the lunar exploration in 2019. Although low energy transfers, such as ballistic lunar transfer, are more and more welcome nowadays, translunar injection using phasing loops is still a safer and easier choice for an inexperienced space agency. This paper, as an extended work of, 1 intends to develop a generic design process applicable to an arbitrarily given initial and final conditions. In specific, this problem can be formulated as a two-point boundary value problem (TPBVP) whose conditions include initial time, initial position of the lunar probe, arrival time, and desired final position. There are two major contributions achieved in this paper. In1 the probe only aims roughly at the moon, in this paper, however, a more specific location is targeted. Moreover, the influence of the resolution of the probe thruster is also analyzed. The 2BP assumption is initially employed to determine coarse parameters. Then an algorithm of iterations is proposed to correct the trajectory subject to major perturbations, such as J2, lunar gravity and solar gravity, etc. In order to tune the parameters more efficiently, the ER3BP environment and Lambert?s theorem are also introduced in the process. The Systems Tool Kit (STK) is also used to simulate the trajectory with the found parameters under the fully perturbed environment. The developed algorithm in this paper is potentially applicable to various lunar mission scenarios using phasing-loop transfer provided desired initial and terminal conditions.

description: Excitons, electron-hole pairs bound by the Coulomb potential, are fundamental quasiparticles of coherent light-matter interaction energizing processes from photosynthesis to optoelectronics. Excitons are observed in semiconductors, and their existence is implicit in the quantum theory of metals, yet their appearance is tenuous due to the screening of the Coulomb interaction on few femtosecond timescale. Here we present direct evidence for the dominant transient excitonic response at a Ag(111) surface, which precedes the full screening of the Coulomb interaction, in the course of a three-photon photoemission process with <15 femtosecond laser pulses. Electron-hole pair interaction through the excitonic response introduces coherent quasiparticle correlations beyond the single-particle description of the optics of metals, which dominate the multi-photon photoemission process.

description: With the impending ban on hydrazine in the space sector, a great interest in green propulsion systems has developed. Therefore, the Institute of Space Systems of the University of Stuttgart is developing a water propulsion system that is scheduled to fly on the institute\'s ROMEO mission at the end of 2025. This work focuses on redesigning and improving the flight-capable electrolysis unit. To determine the cause of losses, impedance measurements are conducted on the static-water-fed electrolyzer. The data is used to improve the cell design by using porous media to increase water diffusion rates. A failure mode and effects analysis (FMEA) of water propulsion systems is conducted and applied to the design to improve system reliability.

description: In a recent paper, a new parametrization for the dark matter (DM) speed distribution f(v) was proposed for use in the analysis of data from direct detection experiments. This parametrization involves expressing the logarithm of the speed distribution as a polynomial in the speed v. We present here a more detailed analysis of the properties of this parametrization. We show that the method leads to statistically unbiased mass reconstructions and exact coverage of credible intervals. The method performs well over a wide range of DM masses, even when finite energy resolution and backgrounds are taken into account. We also show how to select the appropriate number of basis functions for the parametrization. Finally, we look at how the speed distribution itself can be reconstructed, and how the method can be used to determine if the data are consistent with some test distribution. In summary, we show that this parametrization performs consistently well over a wide range of input parameters and over large numbers of statistical ensembles and can therefore reliably be used to reconstruct both the DM mass and speed distribution from direct detection data.

description: Millisecond pulsars (MSPs) are a growing class of gamma-ray emitters. Pulsed gamma-ray signals have been detected from more than 40 MSPs with the Fermi Large Area Telescope (LAT). The wider radio beams and more compact magnetospheres of MSPs enable studies of emission geometries over a broader range of phase space than non-recycled radio-loud gamma-ray pulsars. We have modeled the gamma-ray light curves of 40 LAT-detected MSPs using geometric emission models assuming a vacuum retarded-dipole magnetic field. We modeled the radio profiles using a single-altitude hollow-cone beam, with a core component when indicated by polarimetry; however, for MSPs with gamma-ray and radio light curve peaks occurring at nearly the same rotational phase we assume that the radio emission is co-located with the gamma rays and caustic in nature. The best-fit parameters and confidence intervals are determined using a maximum likelihood technique. We divide the light curves into three model classes, with gamma-ray peaks trailing (Class I), aligned (Class II) or leading (Class III) the radio peaks. Outer gap and slot gap (two-pole caustic) models best fit roughly equal numbers of Class I and II, while Class III are exclusively fit with pair-starved polar cap models. Distinguishing between the model classes based on typical derived parameters is difficult. We explore the evolution of magnetic inclination angle with period and spin-down power, finding possible correlations. While the presence of significant off-peak emission can often be used as a discriminator between outer gap and slot gap models, a hybrid model may be needed.

description: A gravel deflector is a protective device installed on the aircraft to prevent debris from being thrown up by the rotating wheels. For the integration in the C295 aircraft, it was designed to be attached it to the landing gear, as a kit. In order to support the design, a model able to compute the interface loads with the bay and the landing gear was built. This model takes into account the aerodynamics, the structural flexibility, the hydraulic system functionality and the kinematics in order to obtain realistic loads. The model has been developed in MSC Adams software, and it has been validated against laboratory tests in order to check that the loads used for design are correct. Copyright 2023 by First Author.

description: The upper critical field $H_{c2}$ and its anisotropy are calculated for order parameters with line nodes at equators, $k_z=0$, of the Fermi surface of uniaxial superconductors. It is shown that characteristic features found in Fe-based materials -- a nearly linear $H_{c2}(T)$ in a broad $T$ domain, a low and increasing on warming anisotropy $γ_H= H_{c2,ab}/ H_{c2,c}\, $ -- can be caused by competing effects of the equatorial nodes and of the Fermi surface anisotropy. For certain material parameters, $γ_H(T)-1$ may change sign on warming in agreement with recorded behavior of FeTeS system. It is also shown that the anisotropy of the penetration depth $γ_λ= λ_c/λ_{ab} $ decreases on warming to reach $γ_H$ at $T_c$ in agreement with data available. For some materials $γ_λ(T)$ may change on warming from $γ_λ>1$ at low $T$s to $γ_λ<1$ at high $T$s.

description: BACKGROUND: Diet may impact important risk factors for endometrial cancer such as obesity and inflammation. However, evidence on the role of specific dietary factors is limited. We investigated associations between dietary fatty acids and endometrial cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC). METHODS: This analysis includes 1,886 incident endometrial cancer cases and 297,432 non-cases. All participants were followed up for a mean of 8.8 years. Multivariable Cox proportional hazard models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) of endometrial cancer across quintiles of individual fatty acids estimated from various food sources quantified through food frequency questionnaires in the entire EPIC cohort. The false discovery rate (q-values) was computed to control for multiple comparisons. RESULTS: Consumption of n-6 γ-linolenic acid was inversely associated with endometrial cancer risk (HR comparing 5th with 1st quintileQ5-Q1=0.77, 95% CI = 0.64; 0.92, ptrend=0.01, q-value = 0.15). This association was mainly driven by γ-linolenic acid derived from plant sources (HRper unit increment=0.94, 95%CI= (0.90;0.98), p = 0.01) but not from animal sources (HRper unit increment= 1.00, 95%CI = (0.92; 1.07), p = 0.92). In addition, an inverse association was found between consumption of n-3 α-linolenic acid from vegetable sources and endometrial cancer risk (HRper unit increment= 0.93, 95%CI = (0.87; 0.99), p = 0.04). No significant association was found between any other fatty acids (individual or grouped) and endometrial cancer risk. CONCLUSION: Our results suggest that higher consumption of γ-linolenic acid and α-linoleic acid from plant sources may be associated with lower risk of endometrial cancer.

description: Lehnert and Schweitzer show in [20] that R. Thompson's group $V$ is a co-context-free ($co\mathcal{CF}$) group, thus implying that all of its finitely generated subgroups are also $co\mathcal{CF}$ groups. Also, Lehnert shows in his thesis that $V$ embeds inside the $co\mathcal{CF}$ group $\mathrm{QAut}(\mathcal{T}_{2,c})$, which is a group of particular bijections on the vertices of an infinite binary $2$-edge-colored tree, and he conjectures that $\mathrm{QAut}(\mathcal{T}_{2,c})$ is a universal $co\mathcal{CF}$ group. We show that $\mathrm{QAut}(\mathcal{T}_{2,c})$ embeds into $V$, and thus obtain a new form for Lehnert's conjecture. Following up on these ideas, we begin work to build a representation theory into R. Thompson's group $V$. In particular we classify precisely which Baumslag-Solitar groups embed into $V$.

description: Starting from a Lagrangian, the electromagnetic field is quantized in the presence of a body rotating along its axis of symmetry. Response functions and fluctuation-dissipation relations are obtained. A general formula for rotational friction and power radiated by a rotating dielectric body is obtained in terms of the dyadic Green's tensor. Hamiltonian is determined and possible generalizations are discussed. As an example, the rotational friction and power radiated by a spherical dielectric in the vicinity of a semi-infinite dielectric plane is obtained and discussed in some limiting cases.

description: O estudo efetuado teve como objetivo investigar se as atividades promotoras de aprendizagem cooperativa desenvolvidas numa turma do 5.º ano de escolaridade, no contexto da prática de ensino supervisionada em Ciências Naturais, influenciaram as suas aprendizagens. Os resultados obtidos revelaram que os alunos conseguiram adquirir conhecimentos e desenvolver competências sociais e cognitivas através do método de aprendizagem cooperativa. Todavia, é necessário preparar cuidadosamente os alunos e desenvolver o trabalho de grupo, não só como mero trabalho em conjunto, mas também como uma fonte de aprendizagens e partilha de conhecimentos entre os pares. No decorrer das atividades detetaram-se dificuldades por parte dos alunos ao nível da organização e funcionamento do grupo. Pensa-se que isto se deveu ao facto de não estarem habituados a trabalhar em grupo, conforme indica a análise das entrevistas. As dificuldades foram amenizando com a interiorização dos papéis atribuídos e os alunos foram modificando o seu comportamento.

description: Com este estudo pretendeu-se descrever a natureza das conceções e práticas dos educadores de infância e dos professores do 1.º Ciclo do Ensino Básico sobre a educação em ciências e, em particular, sobre a realização de atividades práticas/experimentais. Pretendendo-se, especificamente, compreender a importância atribuída pelos educadores e professores à realização de atividades práticas/experimentais para o processo de ensino-aprendizagem e quais as principais dificuldades sentidas ao implementá-las. Para atingir os objetivos recorreu-se a uma abordagem metodológica de natureza qualitativa, o estudo de caso, e utilizou-se o questionário como instrumento de recolha de dados. Neste estudo participaram quatro educadoras e catorze professores do 1.º ciclo do ensino básico, pertencentes a um agrupamento de escolas, situado no concelho de Santarém. Os resultados desta pesquisa indicam que os profissionais de educação valorizam o ensino experimental das ciências no processo de ensino-aprendizagem, ao destacarem a importância do contacto direto com os fenómenos e da experimentação para alimentar a curiosidade e promover as aprendizagens das crianças/alunos. A respeito das dificuldades sentidas aquando da preparação e implementação das atividades, a maioria das respostas aponta para a falta de materiais/recursos.

description: In his dissertation, Wadge defined a notion of guessability on subsets of the Baire space and gave two characterizations of guessable sets. A set is guessable iff it is in the second ambiguous class (boldface Delta^0_2), iff it is eventually annihilated by a certain remainder. We simplify this remainder and give a new proof of the latter equivalence. We then introduce a notion of guessing with an ordinal limit on how often one can change one's mind. We show that for every ordinal alpha, a guessable set is annihilated by alpha applications of the simplified remainder if and only if it is guessable with fewer than alpha mind changes. We use guessability with fewer than alpha mind changes to give a semi-characterization of the Hausdorff difference hierarchy, and indicate how Wadge's notion of guessability can be generalized to higher-order guessability, providing characterizations for boldface Delta^0_alpha for all successor ordinals alpha>1.

description: Barrier films preventing permeation of gases and moistures are important for many industries ranging from food to medical and from chemical to electronic. From this perspective, graphene has recently attracted particular interest because its defect free monolayers are impermeable to all gases and liquids. However, it has proved challenging to develop large-area defectless graphene films suitable for industrial use. Here we report barrier properties of multilayer graphitic films made by chemical reduction of easily and cheaply produced graphene oxide laminates. They are found to provide a practically perfect barrier that blocks all gases, liquids and aggressive chemicals including, for example, hydrofluoric acid. In particular, if graphene oxide laminates are reduced in hydroiodic acid, no permeation of hydrogen and water could be detected for films as thin as 30 nm, which remain optically transparent. The films thicker than 100 nm become completely impermeable. The exceptional barrier properties are attributed to a high degree of graphitization of the laminates and little structural damage during reduction. This work indicates a close prospect of thin protective coatings with stability and inertness similar to that of graphene and bulk graphite, which can be interesting for numerous applications.
