description: Starting from Shannon's definition of dynamic entropy, we proposed a simple theory to describe the transition between different rare event related dynamic states in condensed matters, and used it to investigate high pressure ice VII. Instead of the thermodynamic intensive quantities such as the temperature and pressure, a dynamic intensive quantity named dynamic field is taken as the controlling variable for the transition. Based on the dynamic entropy versus dynamic field curve, two dynamic states corresponding to ice VII and dynamic ice VII were discriminated rigorously in a pure dynamic view. Their microscopic differences were assigned to the dynamic patterns of proton transfer. This study puts a similar dynamical theory used in earlier studies of glass models on a simple and more fundamental basis, which could be applied to describe the dynamic states of realistic and more condensed matter systems.

description: We discuss fermionic zero modes in the two-dimensional chiral p-wave superconductors. We show quite generally, that without fine-tuning, in a macroscopic sample there is only one or zero of such Majorana-fermion modes depending only on whether the total vorticity of the order parameter is odd or even, respectively. As a special case of this, we find explicitly the one zero mode localized on a single odd-vorticity vortex, and show that, in contrast, zero modes are absent for an even-vorticity vortex. One zero mode per odd vortex persists, within an exponential accuracy, for a collection of well-separated vortices, shifting to finite E or -E energies as two odd vortices approach. These results should be useful for the demonstration of the non-Abelian statistics that such zero-mode vortices are expected to exhibit, and for their possible application in quantum computation.

description: Report D7.1 Analysis of Market Trends and Practices in Collaborative Production Engineer and Co-creation is an outcome of Task 7.1, which creates an overview of existing market trends and practices dealing with collaborative production across Europe and internationally. The report provides a review of co-creation practices and case studies within current industry practices, and regarding consumer driven customisation and prosumerism. More specifically, the analysis sheds light on the history and spread of community approaches to makerspaces and fab labs; the common processes, practices and tools used in similar makerspaces contexts (hackerspaces), and their suitability along with relevant key success and failure factors. The analysis provides a set of guidelines on how to apply co-creation and open-innovation methodologies on key iPRODUCE concepts, together with an overview of how local stakeholders and communities can be involved and activated.
Zwischen Analytischem Pragmatismus und Quietismus

description: Dieser Artikel untersucht den meta-philosophischen Graben, der sich durch die  P i t t s b u r g h e r  S c h u l e  der zeitgenössischen Philosophie zieht. Es handelt sich dabei um eine Meinungsverschiedenheit über die Angemessenheit und Erfolgsaussichten philosophischer Erläuterungsversuche, in denen begriffliche Praktiken, welche wir nur implizit beherrschen, durch die Kombination einfacher und einfach zu überblickender praktischer Regeln nachkonstruiert werden. Während solche philosophischen Rekonstruktionen für Robert Brandom zu einem besseren Verständnis der relevanten Begriffe bzw. Vokabulare führen und damit ein taugliches Mittel für die analytische Philosophie sein können, hält John McDowell sie für Symptome eines fehlerhaften Verständnisses diskursiver Praxis und ihr Scheitern für unvermeidbar. Nach McDowell liegt die Aussichtslosigkeit („linearer“) philosophischer Rekonstruktionen im Holismus der Sprachkompetenz und der Intentionalität begründet: Zwischen konkreten begrifflichen Fähigkeiten gibt es holistische (und damit letztlich zirkuläre) Voraussetzungsverhältnisse. Dieser Artikel verteidigt Brandoms These der Kompatibilität zwischen dem von McDowell zitierten Holismus und der Möglichkeit philosophischer Rekonstruktionen mit einem konkreten Beispiel einer glückenden Rekonstruktion, welche in einer zentralen Hinsicht als „linear“ bezeichnet werden könnte. Schließlich werden zwei mögliche Antworten McDowells skizziert, aus denen sich Raum für eine Fortführung der Debatte ergeben könnte.

New algorithms for adaptive optics point-spread function reconstruction

description: Context. The knowledge of the point-spread function compensated by adaptive optics is of prime importance in several image restoration techniques such as deconvolution and astrometric/photometric algorithms. Wavefront-related data from the adaptive optics real-time computer can be used to accurately estimate the point-spread function in adaptive optics observations. The only point-spread function reconstruction algorithm implemented on astronomical adaptive optics system makes use of particular functions, named $U\_{ij}$. These $U\_{ij}$ functions are derived from the mirror modes, and their number is proportional to the square number of these mirror modes. Aims. We present here two new algorithms for point-spread function reconstruction that aim at suppressing the use of these $U\_{ij}$ functions to avoid the storage of a large amount of data and to shorten the computation time of this PSF reconstruction. Methods. Both algorithms take advantage of the eigen decomposition of the residual parallel phase covariance matrix. In the first algorithm, the use of a basis in which the latter matrix is diagonal reduces the number of $U\_{ij}$ functions to the number of mirror modes. In the second algorithm, this eigen decomposition is used to compute phase screens that follow the same statistics as the residual parallel phase covariance matrix, and thus suppress the need for these $U\_{ij}$ functions. Results. Our algorithms dramatically reduce the number of $U\_{ij}$ functions to be computed for the point-spread function reconstruction. Adaptive optics simulations show the good accuracy of both algorithms to reconstruct the point-spread function.

description: We present detailed observations of photoionization conditions and galaxy kinematics in eleven z$=1.39-2.59$ radio-loud quasar host galaxies. Data was taken with OSIRIS integral field spectrograph (IFS) and the adaptive optics system at the W.M. Keck Observatory that targeted nebular emission lines (H$β$,[OIII],H$α$,[NII]) redshifted into the near-infrared (1-2.4 \micron). We detect extended ionized emission on scales ranging from 1-30 kpc photoionized by stars, shocks, and active galactic nuclei (AGN). Spatially resolved emission-line ratios indicate that our systems reside off the star formation and AGN-mixing sequence on the Baldwin, Phillips $\&$ Terlevich (BPT) diagram at low redshift. The dominant cause of the difference between line ratios of low redshift galaxies and our sample is due to lower gas-phase metallicities, which are 2-5$\times$ less compared to galaxies with AGN in the nearby Universe. Using gas velocity dispersion as a proxy to stellar velocity dispersion and dynamical mass measurement through inclined disk modeling we find that the quasar host galaxies are under-massive relative to their central supermassive black hole (SMBH) mass, with all systems residing off the local scaling ($M_{\bullet}-σ~$,$M_{\bullet}-M_{*}~$) relationship. These quasar host galaxies require substantial growth, up to an order of magnitude in stellar mass, to grow into present-day massive elliptical galaxies. Combining these results with part I of our sample paper (Vayner et al. 2021) we find evidence for winds capable of causing feedback before the AGN host galaxies land on the local scaling relation between black hole and galaxy stellar mass, and before the enrichment of the ISM to a level observed in local galaxies with AGN.

description: In this article, we study the particle dynamics around a static and spherically symmetric Bardeen-Kiselev black hole (BK BH) which is a solution of the Einstein-non-linear Maxwell field equations along with a quintessential field. We discuss its essential geometrical properties such as scalar invariants and size of innermost stable circular orbits. Dynamics of test particles around the BH is also studied. Moreover, we also computed the fundamental frequencies of a test particle orbiting the BH in a slightly perturbed orbit. Further, the degeneracy relations between the spin of rotating Kerr BH and magnetic charge of the BK BH at the values of the quintessential parameter $ω_q=-1/3$ and in terms of the same values of innermost stable circular orbits (ISCOs) radius, energy efficiency, twin-peaks quasiperiodic oscillations (QPOs) frequencies and impact parameter for photon are also discussed in detail. Finally, we have investigated the relationship between the shadow radius and the real part of the quasinormal mode (QNM) frequency.

description: The critical role that Network Time Protocol (NTP) plays in the Internet led to multiple efforts to secure it against time-shifting attacks. A recent proposal for enhancing the security of NTP with Chronos against on-path attackers seems the most promising one and is on a standardisation track of the IETF. In this work we demonstrate off-path attacks against Chronos enhanced NTP clients. The weak link is a central security feature of Chronos: The server pool generation mechanism using DNS. We show that the insecurity of DNS allows to subvert the security of Chronos making the time-shifting attacks against Chronos-NTP even easier than attacks against plain NTP.

description: This work presents a series of highly-accurate excited-state properties obtained using high-order coupled-cluster (CC) calculations performed with a series of diffuse containing basis sets, as well as extensive comparisons with experimental values. Indeed, we have computed both the main ground-to-excited transition property, the oscillator strength, as well as the ground- and excited-state dipole moments, considering {thirteen} small molecules (hydridoboron, hydrogen chloride, water, hydrogen sulfide, boron fluoride, carbon monoxide, dinitrogen, ethylene, formaldehyde, thioformaldehyde, nitroxyl, {fluorocarbene}, and silylidene). We systematically include corrections up to the quintuple (CCSDTQP) in the CC expansion and extrapolate to the complete basis set limit. When comparisons with experimental measurements are possible, that is, when a number of consistent experimental data can be found, theory typically provides values falling within the experimental error bar for the excited-state properties. Besides completing our previous studies focussed on transition energies (\textit{J.~Chem.~Theory Comput.} \textbf{14} (2018) 4360--4379, \textit{ibid.}~\textbf{15} (2019) 1939--1956, \textit{ibid.}~\textbf{16} (2020) 1711--1741, and \textit{ibid.}~\textbf{16} (2020) 3720--3736), this work also provides ultra-accurate dipoles and oscillator strengths that could be employed for future theoretical benchmarks.

description: The mechanism of adsorption of the 1,4,5,8-naphthalene-tetracarboxylic-dianhydride (NTCDA) molecule on the Ag(110) surface is elucidated on the basis of extensive density functional theory calculations. This molecule, together with its perylene counterpart, PTCDA, are archetype organic semiconductors investigated experimentally over the past 20 years. We find that the bonding of the molecule to the substrate is highly site-selective, being determined by electron transfer to the LUMO of the molecule and local electrostatic attraction between negatively charged carboxyl oxygens and positively charged silver atoms in [1-10] atomic rows. The adsorption energy in the most stable site is 0.9eV. A similar mechanism is expected to govern the adsorption of PTCDA on Ag(110) as well.

description: Central compact objects are young neutron stars emitting thermal X-rays with bolometric luminosities $L_X$ in the range $10^{32}$-$10^{34}$ erg/s. Gourgouliatos, Hollerbach and Igoshev recently suggested that peculiar emission properties of central compact objects can be explained by tangled magnetic field configurations formed in a stochastic dynamo during the proto-neutron star stage. In this case the magnetic field consists of multiple small-scale components with negligible contribution of global dipolar field. We study numerically three-dimensional magneto-thermal evolution of tangled crustal magnetic fields in neutron stars. We find that all configurations produce complicated surface thermal patterns which consist of multiple small hot regions located at significant separations from each other. The configurations with initial magnetic energy of $2.5-10\times 10^{47}$ erg have temperatures of hot regions that reach $\approx 0.2$ keV, to be compared with the bulk temperature of $\approx 0.1$ keV in our simulations with no cooling. A factor of two in temperature is also seen in observations of central compact objects. The hot spots produce periodic modulations in light curve with typical amplitudes of $\leq 9-11$ %. Therefore, the tangled magnetic field configuration can explain thermal emission properties of some central compact objects.

description: Innovative products are interacting with the users based on smart sensors and algorithms. Logistics as one example is changing when automated guided vehicles are integrated in the process, supporting or even replacing workers. The way these products are interacting with humans and how they react to certain situations, will determine usability and user experience and therefore the success of use. Developing such products is based on innovative concepts that need to be evaluated and refined at early project stages. Using virtual-reality based user scenarios is one adequate option to do so. This paper describes technical as well as study-based approaches on how potential concepts are realized as virtual prototypes and evaluated by real users. It concludes with the evaluation results of a pilot study but also with general limitations and benefits as best practice advice for this kind of virtual prototyping techniques.

Augenphysiologische Reaktion auf Schreck – Perspektive für den Arbeitsschutz durch Eye-Tracking

description: Eye-Tracking und Pupillometrie bieten einen umfangreichen Einblick in Wahrnehmung und Erleben von Personen in verschiedensten Kontexten. So lassen sich aus den Pupillen- und Blickbewegungsdaten beispielsweise Informationen über Aufmerksamkeitsprozesse, visuelle Suchmechanismen, kognitive Beanspruchung oder Erregung gewinnen. Da augenphysiologische Reaktionen sehr anfällig für Störvariablen sind, finden Datenerhebungen bislang nur in standardisierten Experimentaldesigns unter kontrollierten Helligkeitsbedingungen und stabiler Kopfposition statt. Zur Nutzbarmachung dieser Erkenntnisse für Alltagssituationen wurde ein mobiles Eye-Tracking-System zum Einsatz gebracht. In 2 alltagsnahen Einzelfallstudien (während einer Autofahrt und einer handwerklichen Tätigkeit) fanden sich spezifische Muster in den Pupillendaten, wenn Probanden in eine Schrecksituation versetzt wurden. Die Daten lassen die Vermutung zu, dass dieses Muster mit steigender „echter Bedrohung“ für den Organismus stärker ausgeprägt ist. Weiterführende Studien diesbezüglich sind in Vorbereitung. Gegenwärtig erfolgt die Entwicklung geeigneter Filter, mit denen sich diese Muster in Echtzeit in einem alltagstypischen Eye-Tracking-Datenstrom identifizieren lassen. Ziel ist die Entwicklung eines Algorithmus, der schreckbezogene augenphysiologische Reaktionen in Echtzeit nutzbar gestalten lässt. Dieser Algorithmus kann Anwendung in verschiedenen arbeitsbezogenen und industriellen Kontexten finden, z.B. als ergänzendes Sicherheitssystem im Umgang mit autonomen Systemen oder Mensch-Roboter-Kollaborationen sowie als ergonomische Einrichtung.

description: Needle-like metallic particles have been suggested to explain a wide variety of astrophysical phenomena, ranging from the mid-infrared interstellar extinction to the thermalization of starlight to generate the cosmic microwave background. These suggestions rely on the amplitude and the wavelength dependence of the absorption cross sections of metallic needles. On the absence of an exact solution to the absorption properties of metallic needles, their absorption cross sections are often derived from the antenna approximation. However, it is shown here that the antenna approximation is not an appropriate representation since it violates the Kramers-Kronig relation. Stimulated by the recent discovery of iron whiskers in asteroid Itokawa and graphite whiskers in carbonaceous chondrites, we call for rigorous calculations of the absorption cross sections of metallic needle-like particles, presumably with the discrete dipole approximation. We also call for experimental studies of the formation and growth mechanisms of metallic needle-like particles as well as experimental measurements of the absorption cross sections of metallic needles of various aspect ratios over a wide wavelength range to bound theoretical calculations.

description: The importance and efficacy of formalized treatment for drug abuse and  dependence, combined with high attrition rates in drug treatment settings, emphasize  the need for research to help understand what factors influence an individual’s  decision to engage in treatment. The purpose of this study was to test a model of  treatment engagement in which the effects of psychiatric distress, family and social  problems, and religious function attendance on treatment engagement were mediated  by motivation to change. It was hypothesized that greater psychiatric distress, fewer  family and social problems, and more frequent religious function attendance would  increase treatment engagement both directly and indirectly through the hypothesized  increase in motivation to change. It was also hypothesized that the strength of the  model would differ significantly for men and women in the sample.  One hundred seventy- eight participants attending drug- free outpatient  treatment and participating in a larger study called the STOP Project were included in  this secondary analysis. Path analysis was used to test the model for the entire sample  as well as separately for the 112 male and the 66 female participants. Results did not  support the hypothesis that motivation to change would act as a mediator in the  model. The statistical significance of psychiatric distress, family and social problems,  and religious function attendance as predictors of treatment engagement was not  supported, nor was there support for the link between these variables and motivation  to change. Treatment site, a covariate in the model, predicted treatment engagement  well and legal problems, also a covariate in the model, significantly predicted  motivation for change in the model. These findings support the existing literature  which highlights the importance of treatment program design, in particular how  comprehensive and multifaceted the program is for addressing the various needs of  treatment attendees. The findings further support the existing literature which  highlights the role of legal coercion for motivating individuals to change drug use  behaviors. The results are discussed in terms of both clinical and research  significance.

description: Der Beitrag stellt ein neuartiges additives Fertigungsverfahren für elektrische Maschinen bzw. für Komponenten dieser vor. Das Verfahren wurde entwickelt, um konventionelle polymerbasierte Isolationsstoffe in elektrischen Maschinen, durch keramische Werkstoffe zu ersetzen. Diese weisen bessere thermische Eigenschaften, wie eine höhere thermische Beständigkeit und eine größere Wärmeleitfähigkeit auf. Dadurch ist eine Erhöhung der Leistungsdichte möglich und die Grenze der Einsatztemperatur kann deutlich nach oben verschoben werden. Das Verfahren ermöglicht ebenso eine vollständig freie dreidimensionale Geometriegestaltung, wodurch Maschinentopologien möglich werden, die mit konventionellen Fertigungsverfahren nur mit großem Aufwand bzw. gar nicht realisierbar waren. Zusätzlich lassen sich während des Druckprozesses spezielle Kühlstrukturen herstellen, die zu einer weiteren Steigerung der Leistungsdichte beitragen können. Damit stellt der 3D Multimaterialdruck eine zielorientierte Entwicklung zur Lösung eines vorhandenen Problems dar, wodurch es sich in dieser Hinsicht von den meisten anderen als 3D-Druck bezeichneten Herstellungsverfahren unterscheidet.

description: Self-assembly refers to the organization of similar components in an ordered fashion, without manual manipulation.  Octadecyltrichlorosilane (OTS) (CH3(CH2)17SiCl3) is a type of self-assembling molecule that when adsorbed onto a surface, assembles itself into a close-packed monolayer.  The formation of the OTS monolayer on a silicon oxide surface causes a change in the hydrophobicity of the surface and is typically measured using water contact angle measurements.  The presence of these molecules can also be monitored using FTIR spectroscopy due to the abundance of C-H bonds.  A calibration standard has been found to relate the two measurement techniques as they pertain to this application. The ability of OTS to alter surface chemistry has also allowed us to use it as a resist for the atomic layer deposition (ALD) of metal-oxide thin films.  We also investigate the formation of metal-oxide nanostructures using supercritical carbon dioxide assisted deposition (sc CO2) in nanotemplates and how the application of self-assembled monolayer resists can aid in nanostructure production.

description: We have investigated charge and spin transport in n-type metallic GaAs nanowires (~ 10^17 cm^-3 doping level), grown by hydride vapor phase epitaxy (HVPE) on Si substrates. This was done by exciting the nanowire by tightly-focussed circularly-polarized light and by monitoring the intensity and circular polarization spectrum as a function of distance from the excitation spot. The spin-polarized photoelectrons give rise to a well-defined feature in the nearbandgap spectrum, distinct from the main line due to recombination of the spin-unpolarized electrons of the Fermi sea with the same minority photoholes. At a distance of 2 (micro)m, only the main line remains, implying that photoelectrons have reached a charge thermodynamic equilibrium with the Fermi sea. However, although no line is present in the intensity spectrum at the corresponding energy, the circular polarization is still observed at the same energy in the spectrum, implying that photoelectrons have preserved their spin orientation and that the two spin reservoirs remain distinct. Investigations as a function of distance to the excitation spot show that, depending on excitation power, a photoelectron spin polarization of 20% can be transported over a record distance of more than 20 (micro)m. This finding has potential applications for long distance spin transport in n-type doped nanowires.

description: A small fraction of gamma-ray bursts (GRBs) exhibit blackbody emission in the X-ray spectra, the origin of which is debated. In order to gain a more complete understanding of this phenomenon, we present a search for blackbody components in 116 GRBs with known redshifts observed by {\it Swift}~XRT. A time-resolved spectral analysis is carried out and the significance of the blackbody is assessed with respect to an absorbed power-law model. We report nine new detections and confirm the previously reported blackbody in GRB~171205A. Together with our previous results, there are a total of 19 GRBs with significant blackbody emission in a sample of 199 GRBs observed by {\it Swift} over 13 years. The detections include one short GRB and two low-luminosity GRBs. We estimate fireball parameters from the blackbody components and note that the blackbody luminosity is correlated with the temperature and inferred Lorentz factor. There is a large spread in the properties of the blackbody components and the light curves, which points to different origins for the emission. In about a third of the GRBs, the blackbody is clearly associated with late prompt emission from the jet. The rest of the sample includes cases that are fully consistent with the expectations from a cocoon, as well cases that may be explained by high-latitude emission or more energetic cocoons. These results indicate that thermal emission is associated with all parts of the jet.

Year: 2018

description: In diesem Beitrag werden mobile Assistenzsysteme, sog. Exoskelette, mit ihren charakteristischen Eigenschaften vorgestellt. Schwerpunkte bilden die Entwicklung der Mechanik für die Nachbildung der menschlichen Bewegung und das Antriebssystem. Auf Grundlage der menschlichen Anatomie, mit Bezug zum Schultergürtel, Schultergelenk und Ellenbogengelenk, wird ein Mechanismus entwickelt, der die Armbewegung beim Heben, Halten und Tragen von Lasten nachbilden kann. Weiterführend wird die Entwicklung eines aktiven Antriebssystems für die Unterstützung der zuvor genannten Aufgaben beschrieben. Für die Auslegung werden Richtwerte der Bundesanstalt für Arbeitsschutz und Arbeitsmedizin (BAuA) herangezogen. Der Einsatz pneumatischer Muskeln als Aktuator bringt Vorteile hinsichtlich eines hohen spezifischen Arbeitsvermögens mit sich. Ein Nachteil ist jedoch die charakteristisch nichtlineare Kraft-Kontraktionskennlinie. Es folgt eine Beschreibung für die ungleichmäßige Übersetzung pneumatischer Muskeln mit einem Bandmechanismus. Die verwendete Methode gestattet nicht nur eine Kompensation der nachteiligen, degressiven Kraftkennlinie. Sie erlaubt darüber hinaus die anwendungsspezifische Veränderung des Arbeitskennfeldes. Abschließend erfolgt die Überführung des Bandmechanismus in eine zweistufige Übersetzung, welche die Voraussetzungen pneumatischer Muskeln für den Einsatz in mobilen Anwendungen verbessert.
