description: Das Gasthörenden- und Seniorenstudium der Leibniz Universität Hannover (GHS) führt seit ihrem Beginn in unregelmäßigen Abständen Befragungen unter den Teilnehmenden durch. Die aktuelle Befragung im Sommersemester 2019 bildet die Zusammensetzung und die Situation der GHS-Studierenden ab und zeichnet mit Blick auf die Vorgängerstudien die Entwicklungen im Zeitverlauf nach. Im Vordergrund stehen dabei zunächst Fragen der Ungleichheit und der Partizipation. Auf Basis dieser quantitativen Befragungsdaten liegt der Fokus im Weiteren auf der Erschließung der individuellen Bildungsbedürfnisse, die in die Dimenensionen Interessen, objektive Bedingungen, Lern- und Arbeitsverhalten und Teilnahmemotive ausdifferenziert werden. Dafür werden die partizipationsbeeinflussenden individuellen sozio-demografischen Eigenschaften und die soziostrukturellen Kontextmerkmale mit den Bildungsbedürfnissen der GHS-Studierenden in Beziehung gesetzt. Aus den Daten zur Bildungsbedürfnisdimension Teilnahmemotive lassen sich zudem vier Motivgruppen extrahieren und Erkenntnisse über de Motivlagen bestimmter Teilgruppen der GHS-Studierenden ableiten.

description: We observationally investigate the relation between the photoelectric heating efficiency in PDRs and the charge of PAHs, which are considered to play a key role in photoelectric heating. Using PACS onboard Herschel, we observed six PDRs spanning a wide range of FUV radiation fields (G_0=100-10^5). To measure the photoelectric heating efficiency, we obtained the intensities of the main cooling lines, i.e., the [OI]63um, 145um, and [CII]158um, as well as the FIR continuum intensity. We used Spitzer/IRS spectroscopic mapping observations to investigate the MIR PAH features in the same regions. We decomposed the MIR PAH emission into that of neutral (PAH^0) and positively ionized (PAH^+) species to derive the fraction of the positively charged PAHs, and compare it to the photoelectric heating efficiency. The heating efficiency traced by ([OI]63um+[OI]145um+[CII]158um) / TIR, ranges between 0.1% and 0.9% in different sources, and the fraction of PAH^+ relative to (PAH^0 + PAH^+) spans from 0(+11)% to 87(+/-10)%. All positions with a high PAH^+ fraction show a low heating efficiency, and all positions with a high heating efficiency have a low PAH^+ fraction, supporting the scenario in which a positive grain charge results in a decreased heating efficiency. Theoretical estimates of the photoelectric heating efficiency show a stronger dependence on the charging parameter gamma=G_0 T^{1/2}/n_e than the observed efficiency reported in this study, and the discrepancy is significant at low gamma. The photoelectric heating efficiency on PAHs, traced by ([OI]63um+[OI]145um+[CII]158um) / (PAH+[OI]63um+[OI]145um+[CII]158um), shows a much better match between the observations and the theoretical estimates. The good agreement of the photoelectric heating efficiency on PAHs with a theoretical model indicates the dominant contribution of PAHs to the photoelectric heating. (abridged for arXiv)

Testing X-ray Measurements of Galaxy Cluster Gas Mass Fraction Using the Cosmic Distance-Duality Relation

description: We propose a consistency test of some recent X-ray gas mass fraction ($f_{\rm{gas}}$) measurements in galaxy clusters, using the cosmic distance-duality relation, $η_{\rm{theory}}=\dl(1+z)^{-2}/\da$, with luminosity distance ($\dl$) data from the Union2 compilation of type Ia supernovae. We set $η_{\rm{theory}}\equiv1$, instead of assigning any redshift parameterizations to it, and constrain the cosmological information preferred by $f_{\rm{gas}}$ data along with supernova observations. We adopt a new binning method in the reduction of the Union2 data, in order to minimize the statistical errors. Four data sets of X-ray gas mass fraction, which are reported by Allen et al. (2 samples), LaRoque et al. and Ettori et al., are detailedly analyzed against two theoretical modelings of $f_{\rm{gas}}$. The results from the analysis of Allen et al.'s samples prove the feasibility of our method. It is found that the preferred cosmology by LaRoque et al.'s sample is consistent with its reference cosmology within 1-$σ$ confidence level. However, for Ettori et al.'s $f_{\rm{gas}}$ sample, the inconsistency can reach more than 3-$σ$ confidence level and this dataset shows special preference to an $\Ol=0$ cosmology.

description: High-resolution laser patterning offers innovative methods for the manufacturing of three dimensional interconnect devices. The process chain presented in this paper uses cost efficient metal thin-films sputtered on thermoplastic sheets and two-dimensional high speed laser processing, whereas the three-dimensional shape of the end product is realized by deep drawing of the machined sheet. Due to the lower fracture strain of metals in comparison to thermoplastics extensive fragmentation of the deposited metal film occurs during deep drawing; therefore picosecond laser fine structuring is used to provide strain relief in the circuitry and to preserve the conductivity after the drawing process.

description: Hazardous substances such as unexploded ordnance represent a serious threat. It is necessary to develop new methods and equipment for their elimination. For this reason, a laser ablation process is developed where the shell of the objects are weakened in a defined manner to reduce the threat to the environment. This article shows how 25 mm thick steel sheets can be weakened with ablation rates of more than 3000 mm3/min and achieved ablation depths of more than 15 mm by means of an adapted process strategy and an off-axis process gas control. Despite the high incoming process energy, it is ensured that there is no danger to affect the hazardous substances. A critical temperature of 300 °C is not exceeded at the rear surface of the sheet metal.

description: NiTi shape memory alloys are considered to be difficult to machine. Dimensional accuracy can hardly be met especially in micro-machining. Being a non-contact tool and therefore independent from machining forces, the laser is a promising alternative for manufacturing NiTi micro-parts. This paper presents research results on powder bed-based laser sintering of fine NiTi powders. Structures with a minimum width of approximately 50 |um can be generated without losing the special shape memory properties. The structures "remember" the shape which was set in the laser process. We show that phase transformation temperature can be influenced by process parameters.

description: For many lighting applications, light-emitting diodes (LEDs) are replacing traditional light sources providing the possibility for smart and efficient systems as well as a reduction in the product weight. A next step in this development is the integration of laser-based light sources to increase luminance and to further scale down the optics possibly leading to a reduction of necessary resources. This article reviews the possibilities and challenges arising from the use of laser diodes especially compared to current high-power LED systems in terms of efficiency, color-rendering properties, and thermal management. © 2014 Thoss Media and De Gruyter.

description: The recently published GALFA-HI Compact Cloud Catalogue lists 20 neutral hydrogen clouds that might pinpoint previously undiscovered high-latitude dwarf galaxies. Detection of an associated gamma-ray dark matter signal could provide a route to distinguish unambiguously between truly dark matter dominated systems that have accumulated neutral hydrogen but have not successfully ignited star formation and pure gaseous structures devoid of dark matter. We use 4.3 years of Fermi observations to derive gamma-ray flux upper limits in the 1-300 GeV energy range for the sample. Limits on gamma rays from pair annihilation of dark matter are also presented depending on the yet unknown astrophysical factors.

description: The properties of liquid helium have always been a fascinating subject to scientists. The phonon theory of liquids taking into account liquid non-static shear rigidity is employed here for studying internal energy and heat capacity of compressed liquid 4-He. We demonstrate good agreement of calculated and experimental heat capacity of liquid helium at elevated pressures and supercritical temperatures. Unexpectedly helium remains a quantum liquid at elevated pressures for a wide range of temperature supporting both longitudinal and transverse-like phonon excitations. We have found that in the very wide pressure range 5 MPa-500 MPa liquid helium near melting temperature is both solid-like and quantum.

description: Entrepreneurship is one major factor influencing the world we live in. At that, the relationship between entrepreneurship and this world is an interdependent one and entrepreneurial activity in any given territory is an inherently economic geographical process. As a highly multidisciplinary research field, entrepreneurship has been analysed for decades, yet as the world progresses, the entrepreneurial phenomena evolve as well. Sophisticated research needs outstanding data. Plenty manifestations of entrepreneurship are not or not sufficiently covered by such data. There is a need to explore new methods and approaches for data on entrepreneurship to tackle unsolved issues and address newly developing phenomena. Some entrepreneurial events are so rare it is difficult to get quantitative data on them, making them dominated by qualitative case studies. Moreover, other areas in entrepreneurship are so complex, that reliable comparable data need a broad and coordinated approach. This thesis addresses these issues as such, that it contributes to a more complete empirical data body, and it expands the understanding how bespoke methodology leads to phenomenon specific empirical data and ultimately to place based policies and is thus overall advancing entrepreneurship research.
Incorporating independent component analysis and multi-temporal sar techniques to retrieve rapid postseismic deformation

description: This study investigates the ongoing postseismic deformation induced by two moderate mainshocks of Mw 6.1 and Mw 6.0, 2017 Hojedk earthquake in Southern Iran. Available Sentinel-1 TOPS C-band Synthetic Aperture Radar (SAR) images over about one year after the earthquakes are used to analyze the postseismic activities. An adaptive method incorporating Independent Component Analysis (ICA) and multi-Temporal Small BAseline Subset (SBAS) Interferometric SAR (InSAR) techniques is proposed and implemented to recover the rapid deformation. This method is applied to the series of interferograms generated in a fully constructed SBAS network to retrieve the postseismic deformation signal. ICA algorithm uses a linear transformation to decompose the input mixed signal to its source components, which are non-Gaussian and mutually independent. This analysis allows extracting the low rate postseismic deformation signal from a mixture of interferometric phase components. The independent sources recovered from the multi-Temporal InSAR dataset are then analyzed using a group clustering test aiming to identify and enhance the undescribed deformation signal. Analysis of the processed interferograms indicates a promising performance of the proposed method in determining tectonic deformation. The proposed method works well, mainly when the tectonic signal is dominated by the undesired signals, including atmosphere or orbital/unwrapping noise that counts as temporally uncorrelated components.In contrast to the standard SBAS time series method, the ICA-based time series analysis estimates the cumulative deformation with no prior assumption about elevation dependence of the interferometric phase or temporal nature of the tectonic signal. Application of the method to 433 Sentinel-1 pairs within the dataset reports two distinct deformation patches corresponding to the postseismic deformation. Besides the performance of the ICA-based analysis, the proposed method automatically detects rapid or low rate tectonic processes in unfavorable conditions. © Authors 2020. All rights reserved.

Considering the field to be initially in a thermal (or in an even coherent) state, we evaluate the photon number distribution, Wigner function and Mandel's $Q$ parameter of the resulting field. We show graphically that in which order multi-photons are added and subtracted has a noticeable effect on the temporal behavior of these statistical properties.

description: Cavity optomechanics allows the parametric coupling of phonon- and photon-modes in microresonators and is presently investigated in a broad variety of solid-state systems. Optomechanics with superfluids has been proposed as a path towards ultra-low optical- and mechanical-dissipation. However, there have been no optomechanics experiments reported with non-solid phases of matter. Direct liquid immersion of optomechanics experiments is challenging since the acoustic energy simply leaks out to the higher-impedance liquid surrounding the device. Conversely, here we confine liquids inside hollow resonators thereby enabling optical excitation of mechanical whispering-gallery modes at frequencies ranging from 2 MHz to 11,000 MHz (for example, with mechanical Q = 4700 at 99 MHz). Vibrations are sustained even when we increase the fluid viscosity to be higher than that of blood. Our device enables optomechanical investigation with liquids, while light is conventionally coupled from the outer dry side of the capillary, and liquids are provided by means of a standard microfluidic inlet.

description: In der vorliegenden Dissertation wurde ein Targeted Drug delivery System (TDDS) entwickelt. TDDS sollen die kontrollierte Freisetzung eines Wirkstoffes an einem spezifischen Wirkort ermöglichen. Das TDDS der vorliegenden Arbeit besteht aus Polycaprolacton-basierten Polymer-Nanopartikeln. Die Funktionalisierung mit Aptameren auf der Oberfläche der Nanopartikel sorgt für eine spezifische Bindung an den Zielzellen. Aptamere eignen sich u.a. aufgrund ihrer niedrigen Immunogenität gut für den Einsatz im menschlichen Körper. Nach erfolgreich optimierter Herstellung der Nanopartikel, konnte das S15 Aptamer, das gegen die Lungenkrebszelllinie A549 gerichtet ist, auf der Oberfläche immobilisiert werden. Die Nanopartikel hatten eine Größe zwischen 50 und 100 nm, die für Nanoträger ideal ist, um sich in den Zielzellen anreichern zu können und nicht durch die Nieren oder die Leber aus dem Blutkreislauf herausgefiltert zu werden. In die Nanopartikel wurden erfolgreich die Wirkstoffe Paclitaxel und Camptothecin, die gegen verschiedene Arten von Krebs eingesetzt werden, eingekapselt. In Wasser bleiben die mit Wirkstoff beladenen Partikel stabil. Die Freisetzung des Wirkstoffes, die bei unterschiedlichen pH-Werten untersucht wurde, erfolgt bevorzugt in saurem Milieu, welches auch von Tumorzellen ausgebildet wird. Das entwickelte TDDS wurde abschließend in vitro untersucht. Dabei ist die Dichte des auf den Nanopartikeln immobilisierten Aptamers für eine spezifische Bindung an die Zielzellen verantwortlich. Ist die Dichte zu hoch, kann diese aufgrund sterischer Hinderungen zu unspezifischen Bindungen an die Kontrollzelllinie HeLa führen. Weiterhin wurde untersucht, über welchen Weg die Nanopartikel in die Zielzellen aufgenommen werden. Dazu kamen mit S15 konjugierte Quantum Dots (QDs) als Modellpartikel zum Einsatz, die wegen ihrer Fluoreszenzeigenschaften leichter detektierbar waren. Die funktionalisierten QDs werden über die Rezeptorvermittelte Endozytose in die Zelle aufgenommen. Abschließend wurde das entwickelte Targeted Drug Delivery System hinsichtlich seiner Toxizität auf die Zielzellen untersucht. Es konnte gezeigt werden, dass die mit Wirkstoff beladenen und mit S15 funktionalisierten Polymer-Nanopartikel einen toxischen Effekt auf die Lungenkrebszellen haben. Somit konnte in der vorliegenden Arbeit das Targeted Drug Delivery System erfolgreich entwickelt und in vitro eingesetzt werden.

description: We study the effects of decoherence on the entanglement generated by Unruh effect in accelerated frames by using various combinations of an amplitude damping channel, a phase damping channel and a depolarizing channel in the form of multilocal and collective environments. Using concurrence as entanglement quantifier, we show that the occurrence of entanglement sudden death (ESD) depends on different combinations of the channels. The ESD can be avoided under a particular configuration of the channels. We show that the channels can be used to distinguish between a moving and a stationary frame.

For the general member [C] ∈ | H| consider the μn-equivariant isogeny decomposition of the Prym variety Prym(C′/C) of the induced covering f: C′: = f- 1(C) ⟶ C: Prym(C′/C)∼∏d|n,d≠1Pd(C′/C).We show that for the very general member [C] ∈ | H| the isogeny component Pd(C′/ C) is μd-simple with Endμd(Pd(C′/C))≅Z[ζd]. In addition, for the non-ample case we reformulate the result by considering the identity component of the kernel of the map Pd(C′/C)⊂Jac(C′)⟶Alb(S′). © 2022, The Author(s).

description: We study how generic phase transitions taking place in compact stars constructed in the framework of the Eddington-inspired Born-Infeld (EiBI) gravity can lead to anomalous behavior of these stars. For the case with first-order phase transitions, compact stars in EiBI gravity with a positive coupling parameter $κ$ exhibit a finite region with constant pressure, which is absent in general relativity. However, for the case with a negative $κ$, an equilibrium stellar configuration cannot be constructed. Hence, EiBI gravity seems to impose stricter constraints on the microphysics of stellar matter. Besides, in the presence of spatial discontinuities in the sound speed $c_s$ due to phase transitions, the Ricci scalar is spatially discontinuous and contains $δ$-function singularities proportional to the jump in $c_s^2$ acquired in the associated phase transition.

description: The use of self-avatars is gaining popularity thanks to affordable VR headsets. Unfortunately, mainstream VR devices often use a small number of trackers and provide low-accuracy animations. Previous studies have shown that the Sense of Embodiment, and in particular the Sense of Agency, depends on the extent to which the avatar's movements mimic the user's movements. However, few works study such effect for tasks requiring a precise interaction with the environment, i.e., tasks that require accurate manipulation, precise foot stepping, or correct body poses. In these cases, users are likely to notice inconsistencies between their self-avatars and their actual pose. In this paper, we study the impact of the animation fidelity of the user avatar on a variety of tasks that focus on arm movement, leg movement and body posture. We compare three different animation techniques: two of them using Inverse Kinematics to reconstruct the pose from sparse input (6 trackers), and a third one using a professional motion capture system with 17 inertial sensors. We evaluate these animation techniques both quantitatively (completion time, unintentional collisions, pose accuracy) and qualitatively (Sense of Embodiment). Our results show that the animation quality affects the Sense of Embodiment. Inertial-based MoCap performs significantly better in mimicking body poses. Surprisingly, IK-based solutions using fewer sensors outperformed MoCap in tasks requiring accurate positioning, which we attribute to the higher latency and the positional drift that causes errors at the end-effectors, which are more noticeable in contact areas such as the feet.

description: Ions are critical to the structure and stability of polyelectrolytes such as nucleic acids. In this work, we systematically calculated the potentials of mean force between two like-charged nanoparticles in salt solutions by Monte Carlo simulations. The pseudo-spring method is employed to calculate the potential of mean force and compared systematically with the inversed-Boltzmann method. An effective attraction is predicted between two like-charged nanoparticles in divalent/trivalent salt solution and such attraction becomes weakened at very high salt concentration. Our analysis reveals that for the system, the configuration of ion-bridging nanoparticles is responsible for the attraction, and the invasion of anions into the inter-nanoparticles region at high salt concentration would induce attraction weakening rather than the charge inversion effect. The present method would be useful for calculating effective interactions during nucleic acid folding.

description: Managing connected and automated vehicles (CAV) in mixed traffic scenario necessitates special attention when introducing them into the market. The coexistence of CAVs and non-CAVs leads to complex interactions. To simplify the interactions in the envisioned scenario, a strategy that operates CAVs in a platoon which is led by a CAV driven by a human is proposed in this paper. Implementing this strategy in practice requires feasible platooning approaches of assigning CAV roles in platoons (i.e. to be a leader or a follower) and reliable communication between CAVs and roadside units (RSU). Two rudimentary rule-based approaches are designed in this paper and examined in a micro-simulation. All CAVs are assumed to be V2X enabled. CAVs start communicating with each other and RSU when they enter the CAV zone. The RSU require CAVs to follow a certain platooning approach and CAVs cooperate with each other to form platoons. The impacts of different platooning approaches and communication reliability level are evaluated by total travel time and the automated driving mode duration. © 2020 The Authors.

Separability problem for multipartite states of rank at most four

description: One of the most important problems in quantum information is the separability problem, which asks whether a given quantum state is separable. We investigate multipartite states of rank at most four which are PPT (i.e., all their partial transposes are positive semidefinite). We show that any PPT state of rank two or three is separable and has length at most four. For separable states of rank four, we show that they have length at most six. It is six only for some qubit-qutrit or multiqubit states. It turns out that any PPT entangled state of rank four is necessarily supported on a 3x3 or a 2x2x2 subsystem. We obtain a very simple criterion for the separability problem of the PPT states of rank at most four: such a state is entangled if and only if its range contains no product vectors. This criterion can be easily applied since a four-dimensional subspace in the 3x3 or 2x2x2 system contains a product vector if and only if its Pluecker coordinates satisfy a homogeneous polynomial equation (the Chow form of the corresponding Segre variety). We have computed an explicit determinantal expression for the Chow form in the former case, while such expression was already known in the latter case.

(1) Im Text werden die Diskussionen, die an drei Tischen zu den Themen "Können Bibliotheken Menschen in Armut dabei helfen, ihren Alltag zu gestalten?" (2.1), "Können Bibliotheken Menschen in Armut dabei helfen, aus der Armut auszusteigen?" (2.2) und "Können Bibliotheken Kinder und Jugendliche in Armut unterstützen?" (2.3) vorgestellt und diese zusammengefasst. (3) Im Workshop kristallisierte sich heraus, dass viele Kolleginnen und Kollegen am Thema interessiert sind, aber wenig Austausch dazu stattfindet. Grundsätzlich wäre Menschen in Armut zu helfen, wenn Angebote so gestaltet werden, dass sie diese Menschen nicht in ihrer Sozialen Situation diskriminieren, aber sie gleichzeitig am Meisten unterstützen. Gleichzeitig wurden viele Formen von Kooperationen angedacht.

description: In a non-compact setting, the notion of hyperbolicity, and the associated structure of stable and unstable manifolds (for unbounded orbits), is highly dependent on the choice of metric used to define it. We consider the simplest version of this, the analogue for the plane of Anosov diffeomorphisms, studied earlier by W. White and P. Mendes. The two known topological conjugacy classes of such diffeomorphisms are linear hyperbolic automorphisms and translations. We show that if the structure of stable and unstable manifolds is required to be preserved by these conjugacies, the number of distinct equivalence classes of Anosov diffeomorphisms in the plane becomes infinite.

description: DNA has been used in vitro as a computational substrate due to programmable base-pairing interactions. This allows the construction of logic gates, self-assembled shapes, motors, walkers and other nanoscale devices comprised of DNA strands. These strands must be carefully designed in order to correctly perform their function, which requires effective models of the DNA system. The thermodynamics of multiple interacting DNA strands is a well-studied model which can make equilibrium predictions on these systems, but many devices operate far from equilibrium. The prediction of large non-equilibrium systems requires the simulation of a kinetics model, as these are both stochastic and computationally difficult to solve in an exact form. We developed the Multistrand kinetics simulator, which extends the previous work by expanding the kinetics model to handle multiple nucleic acid strands, as well as using optimized algorithms in order to speed up the simulations.
