description: Wie in der Danksagung des in diesem Band p. 85-98 publizierten Beitrags ausgeführt, war es dem Autor leider unmöglich, die sehr bedenkenswerten und wichtigen Anregungen und Denkanstöße der beiden anonymen Gutachter in ihren Reviews derart in den Artikel einzuarbeiten, dass es der Bedeutung der darin angesprochenen Themen hätte gerecht werden können, ohne dadurch von dem eigentlichen, im und mit dem Artikel verfolgten Argument und Anliegen abzuschweifen. Gleichzeitig will der Verf. aber auch nicht auf eine Berücksichtigung dieser Anregungen der beiden Gutachter gänzlich verzichten, denn dazu erscheinen sie als zu wichtig. Daher wird hier die Möglichkeit wahrgenommen, in einem separaten, nur elektronisch veröffentlichten Text etwas genauer auf die Anregungen der Gutachter einzugehen und diese ebenfalls in die fachliche Diskussion einfließen zu lassen.

description: The experimental - calculated method is proposed to determine the full energy peak efficiency (FEPE) of detectors ε(E) in case a measurement of the large-volume samples. Water is used as standard absorber in which the linear attenuation coefficients for photons μ0 (E) is well known. The value μ (E) in sample material (matrix of the sample) is determined experimentally by means of spectrometer. The formulas are given for calculation of the ratio ε(E)/ ε0(E), where ε0(E) is FEPE of the detector for photons those are arising in the container filled with water (it is found by adding in the container of the Reference radioactive solutions). To prove the validity of the method ethanol (density 0,8 g/cm3) and water solutions of salts (density 1,2 and 1,5 g/cm3) were used for simulation of the samples with different attenuation coefficients. Standard deviation between experimental and calculated efficiencies has been about 5 %.

description: The induction equation induces non trivial correlations between the primordial curvature mode and the magnetic mode which is a non linear effect. Assuming a stochastic, gaussian magnetic field the resulting power spectra determining the two point cross correlation functions between the primordial curvature perturbation and the magnetic energy density contrast as well as the magnetic anisotropic stress are calculated approximately. The corresponding numerical solutions are used to calculate the angular power spectra determining the temperature anisotropies and polarization of the cosmic microwave background, $C_{\ell}$. It is found that the resulting $C_{\ell}$ are sub-leading in comparison to those generated by the compensated mode for a magnetic field which only redshifts with the expansion of the universe.The main focus are scalar modes, however, vector modes will also be briefly discussed.

Electronic Energy Transfer: Localized Operator Partitioning of Electronic Energy in Composite Quantum Systems

Subjects: subject: Quantum Physics (quant-ph)

description: A Hamiltonian based approach using spatially localized projection operators is introduced to give precise meaning to the chemically intuitive idea of the electronic energy on a quantum subsystem. This definition facilitates the study of electronic energy transfer in arbitrarily coupled quantum systems. In particular, the decomposition scheme can be applied to molecular components that are strongly interacting (with significant orbital overlap) as well as to isolated fragments. The result leads to the proper electronic energy at all internuclear distances, including the case of separated fragments, and reduces to the well-known Forster and Dexter results in their respective limits. Numerical calculations of coherent energy and charge transfer dynamics in simple model systems are presented and the effect of collisionally induced decoherence is examined.

description: We report the first experimental test of the topological phase predicted by He and McKellar and by Wilkens in 1993: this phase, which appears when an electric dipole propagates in a magnetic field, is connected to the Aharonov-Casher effect by electric-magnetic duality. The He-McKellar-Wilkens phase is quite small, at most 27 mrad in our experiment, and this experiment requires the high phase sensitivity of our atom interferometer with spatially separated arms as well as symmetry reversals such as the direction of the electric and magnetic fields. The measured value of the He-McKellar-Wilkens phase differs by 31% from its theoretical value, a difference possibly due to some as yet uncontrolled systematic errors.

title: Entwicklung einer Methodik für eine modellbasierte und ganzheitliche Fehleranalyse
Creators: name: Bielefeld, Ovidiu
Publisher: name: Bergische Universität Wuppertal
Year: 2021

description: Aktuelle Rückrufaktionen wie bspw. in der Automobilindustrie zeigen, dass derzeit eine einheitliche Fehlerbeschreibung sowie eine ganzheitliche Betrachtung von potentiellen Fehlern in der Nutzungsphase bei der Entwicklung von Produkten fehlen. Zudem führen solche Fehler, die erst – im schlimmsten Fall – in der Nutzungsphase identifiziert werden, zu sehr hohen Fehlerkosten und Imageschäden für das Unternehmen. Diese wissenschaftliche Lücke der fehlenden, ganzheitlichen Betrachtung von potentiellen Fehlern in den frühen Phasen der Produktentwicklung kann zudem auch zur Gefährdung von Menschenleben bis hin zu Todesfällen führen. Um potentielle Fehler in der Nutzungsphase bereits in der Produktentwicklung ganzheitlich zu identifizieren und einheitlich zu beschreiben, ist eine umfassende Untersuchung erforderlich. Dabei werden die folgenden Forschungsschwerpunkte untersucht: Fehlerdefinitionen und deren Klassifizierungen (Forschungsfeld 1 und 3), Methoden der Fehleranalyse in der Produktentwicklung (Forschungsfeld 4) und Ansätze zur Modellierung technischer Produktsysteme (Forschungsfeld 2). Letzteres ist von großer Bedeutung, da durch die Modellierung nicht nur das technische Produkt, sondern auch seine Interaktion mit der Umwelt ganzheitlich analysiert werden kann. Dies bildet die Basis für die ganzheitliche und modellbasierte Fehleranalyse von potentiellen Fehlern in der Nutzungsphase. Zudem sind diese Forschungsfelder miteinander zu verzahnen und in Form einer neuen Methodik weiter zu entwickeln. In der vorliegenden Arbeit wird diese Methodik der modellbasierten und ganzheitlichen Fehleranalyse (MemogaFa) vorgestellt, die eine präventive Fehleridentifikation fördert. Die neue Methodik wurde an zwei Fallbeispielen der Industrie evaluiert. Es zeigte sich, dass Expertenwissen und -erfahrungen zur Bestimmung kritischer, potentieller Nutzungsprozesse systematisch und rückverfolgbar in die frühen Phasen der Produktentwicklung integriert werden konnten. Durch die Nutzung der MemogaFa wurde das Verständnis hinsichtlich mechatronischer, komplexer Produkte erhöht und potentielle Fehlernetzen mittels Szenarien und unter der Einbeziehung von relevanten Faktoren (Effekte, Ereignisse und Umwelt) analysiert. Das im Rahmen dieser Arbeit entwickelte Tool ermöglicht erstmalig, Fehler auf unterschiedlichen Ebenen (vom Groben zum Detail) und in Wechselwirkung mit relevanten Faktoren (Effekte, Umwelt, usw.) systematisch und ganzheitlich zu identifizieren sowie zu beschreiben. Hierdurch wird die Erfüllung vom Produkthaftungsgesetz anhand einer präventiven Identifizierung potentieller Fehler, die zu Personenschaden führen können, erhöht.

description: We present LITTLE THINGS (Local Irregulars That Trace Luminosity Extremes, The HI Nearby Galaxy Survey) that is aimed at determining what drives star formation in dwarf galaxies. This is a multi-wavelength survey of 37 Dwarf Irregular and 4 Blue Compact Dwarf galaxies that is centered around HI-line data obtained with the National Radio Astronomy Observatory (NRAO) Very Large Array (VLA). The HI-line data are characterized by high sensitivity (less than 1.1 mJy/beam per channel), high spectral resolution (less than or equal to 2.6 km/s), and high angular resolution (~6 arcseconds. The LITTLE THINGS sample contains dwarf galaxies that are relatively nearby (less than or equal to 10.3 Mpc; 6 arcseconds is less than or equal to 300 pc), that were known to contain atomic hydrogen, the fuel for star formation, and that cover a large range in dwarf galactic properties. We describe our VLA data acquisition, calibration, and mapping procedures, as well as HI map characteristics, and show channel maps, moment maps, velocity-flux profiles, and surface gas density profiles. In addition to the HI data we have GALEX UV and ground-based UBV and Halpha images for most of the galaxies, and JHK images for some. Spitzer mid-IR images are available for many of the galaxies as well. These data sets are available on-line.

Spontaneous Parity Breaking, Gauge Coupling Unification and Consistent Cosmology with Transitory Domain Walls

description: Formation of transitory domain walls is quite generic in theories with spontaneous breaking of discrete symmetries. Since these walls are in conflict with cosmology, there has to be some mechanism which makes them disappear. We study one such mechanism by incorporating Planck scale suppressed operators within the framework of Left-Right Symmetric Models (LRSM) where Left-Right parity (D parity) is spontaneously broken. We find that this mechanism can not make the walls disappear in minimal versions of LRSM. We propose two viable extensions of this model and show that Planck scale suppressed operators can give rise to successful disappearance of domain walls provided the scale of parity breaking obeys certain limits. We also constrain the scale of parity breaking by demanding successful gauge coupling unification and make a comparison of the unification and cosmology bounds.

description: We report the observation of a premelting transition at chemically sharp solid-liquid interfaces using molecular-dynamics simulations. The transition is observed in the solid-Al/liquid-Pb system and involves the formation of a liquid interfacial film of Al with a width that grows logarithmically as the bulk melting temperature is approached from below, consistent with current theories of premelting. The premelting behavior leads to a sharp change in the temperature dependence of the diffusion coefficient in the interfacial region, and could have important consequences for phenomena such as particle coalescence and shape equilibration, which are governed by interfacial kinetic processes.

description: In this work, the influence of the structure-forming agent on the composition, morphology and oxygen reduction reaction (ORR) activity of Fe-N-C catalysts was investigated. As structure-forming agents (SFAs), dicyandiamide (DCDA) (nitrogen source) or oxalic acid (oxygen source) or mixtures thereof were used. For characterization, cyclic voltammetry and rotating disc electrode (RDE) experiments were performed in 0.1 M H₂SO₄. In addition to this, N₂ sorption measurements and Raman spectroscopy were performed for the structural, and elemental analysis for chemical characterization. The role of metal, nitrogen and carbon sources within the synthesis of Fe-N-C catalysts has been pointed out before. Here, we show that the optimum in terms of ORR activity is achieved if both N- and O-containing SFAs are used in almost similar fractions. All catalysts display a redox couple, where its position depends on the fractions of SFAs. The SFA has also a strong impact on the morphology: Catalysts that were prepared with a larger fraction of N-containing SFA revealed a higher order in graphitization, indicated by bands in the 2nd order range of the Raman spectra. Nevertheless, the optimum in terms of ORR activity is obtained for the catalyst with highest D/G band ratio. Therefore, the results indicate that the presence of an additional oxygen-containing SFA is beneficial within the preparation.

description: A novel approach for solving equations of motion of finite-sized satellite supposed to be moving in a proximity and around the planet in the elliptic restricted three-body problem, ER3BP is presented in this semi-analytical investigation. We consider two primaries, M_Sun and m_planet (the last is secondary in that binary system), both are orbiting around their barycenter on elliptic orbits. Satellite is considered to be the solid ellipsoid having nearly spherical form, with its gravitational potential to be given by a formula of MacCullagh type. Our aim is to revisit previously presented in work [Ashenberg, 1996] approach and to investigate the updated type of the satellite dynamics correlated implicitly to a kind of trapped motion (in the synodic co-rotating Cartesian coordinate system) in so way that satellite will always to be located near the secondary planet, m_planet, moving on quasi-stable elliptic orbit.

description: For $α>0$, the Bargmann projection $P_α$ is the orthogonal projection from $L^2(γ_α)$ onto the holomorphic subspace $L^2_{hol}(γ_α)$, where $γ_α$ is the standard Gaussian probability measure on $\C^n$ with variance $(2α)^{-n}$. The space $L^2_{hol}(γ_α)$ is classically known as the Segal-Bargmann space. We show that $P_α$ extends to a bounded operator on $L^p(γ_{αp/2})$, and calculate the exact norm of this scaled $L^p$ Bargmann projection. We use this to show that the dual space of the $L^p$-Segal-Bargmann space $L^p_{hol}(γ_{αp/2})$ is an $L^{p'}$ Segal-Bargmann space, but with the Gaussian measure scaled differently: $(L^p_{hol}(γ_{αp/2}))^* \cong L^{p'}_{hol}(γ_{αp'/2})$ (this was shown originally by Janson, Peetre, and Rochberg). We show that the Bargmann projection controls this dual isomorphism, and gives a dimension-independent estimate on one of the two constants of equivalence of the norms.

description: We calculate the dominant excitations for the $k$-level ($k\in\mathbb{N}$) Read-Rezayi (RR) states and their particle-hole conjugates, the anti Read-Rezayi ($\bar{\textrm{RR}}$), proposed for quantum Hall states. These states are supposed to be build over the second Landau level with total filling factor $ν=2+ν^*$ with $ν^*=k/(k+2)$ for RR and $ν^*=2/(k+2)$ for $\bar{\textrm{RR}}$. In the $k$-level RR states, based on $\mathbb{Z}_k$ parafermions, the dominant excitations are the fundamental quasiparticles with fractional charge $e^*_k= e/(k + 2)$, with $e$ the electron charge, if $k=2,3$. For k=4 the single-qp and the 2-agglomerate, with charge $2e^*_k$, have the same scaling and both dominate, while for $k>4$ the 2-agglomerates are dominant. Anyway the dominance of the 2-agglomerates can be affected by the presence of environmental renormalizations. For all the $k$-level $\bar{\textrm{RR}}$ states the single-qp and the 2-agglomerate have the same scaling and both dominate. In this case only the presence of environmental renormalizations can make one dominant over the other. We determine the conditions where the environmental renormalizations of the charged and neutral modes make dominant the Abelian 2-agglomerates over the non-Abelian single-quasiparticles in the two models and for any value of $k$. We conclude observing that, according these predictions, the dominance of 2-agglomerates, at very low energies for the $ν=5/2$, can be an interesting indication supporting the validity of the anti-Pfaffian model in comparison to the Pfaffian.

description: Over the past decade, interval arithmetic (IA) has been utilized to determine tolerance bounds of phased array beampatterns. IA only requires that the errors of the array elements are bounded, and can provide reliable beampattern bounds even when a statistical model is missing. However, previous research has not explored the use of IA to find the error realizations responsible for achieving specific bounds. In this study, the capabilities of IA are extended by introducing the concept of ``backtracking'', which provides a direct way of addressing how specific bounds can be attained. Backtracking allows for the recovery of both the specific error realization and the corresponding beampattern, enabling the study and verification of which errors result in the worst-case array performance in terms of the peak sidelobe level. Moreover, IA is made applicable to a wider range of arrays by adding support for arbitrary array geometries with directive elements and mutual coupling, in addition to element amplitude, phase, and positioning errors. Lastly, a simple formula for approximate bounds of uniformly bounded errors is derived and numerically verified. This formula gives insights into how array size and apodization cannot reduce the worst-case peak sidelobe level beyond a certain limit.

description: We present a comprehensive data description for Ks-band measurements of Sgr A*. We characterize the statistical properties of the variability of Sgr A* in the near-infrared, which we find to be consistent with a single-state process forming a power-law distribution of the flux density. We discover a linear rms-flux relation for the flux-density range up to 12 mJy on a timescale of 24 minutes. This and the power-law flux density distribution implies a phenomenological, formally non-linear statistical variability model with which we can simulate the observed variability and extrapolate its behavior to higher flux levels and longer timescales. We present reasons why data with our cadence cannot be used to decide on the question whether the power spectral density of the underlying random process shows more structure at timescales between 25 min and 100 min compared to what is expected from a red noise random process.

description: We study the statistical properties of recurrence times in the self-excited Hawkes conditional Poisson process, the simplest extension of the Poisson process that takes into account how the past events influence the occurrence of future events. Specifically, we analyze the impact of the power law distribution of fertilities with exponent α, where the fertility of an event is the number of aftershocks of first generation that it triggers, on the probability distribution function (pdf) f(τ) of the recurrence times τbetween successive events. The other input of the model is an exponential Omori law quantifying the pdf of waiting times between an event and its first generation aftershocks, whose characteristic time scale is taken as our time unit. At short time scales, we discover two intermediate power law asymptotics, f(τ) ~ τ^{-(2-α)} for τ<< τ_c and f(τ) ~ τ^{-α} for τ_c << τ<< 1, where τ_c is associated with the self-excited cascades of aftershocks. For 1 << τ<< 1/ν, we find a constant plateau f(τ) ~ const, while at long times, 1/ν< τ, f(τ) ~ e^{-ντ} has an exponential tail controlled by the arrival rate νof exogenous events. These results demonstrate a novel mechanism for the generation of power laws in the distribution of recurrence times, which results from a power law distribution of fertilities in the presence of self-excitation and cascades of triggering.

description: The control of the magnetization inversion dynamics is one of the main challenges driving the design of new nanostructured magnetic materials for magnetoelectronic applications. Nanoparticles with onion-like architecture offer a unique opportunity to expand the possibilities allowing to combine different phases at the nanoscale and also modulate the coupling between magnetic phases by introducing spacers in the same structure. Here we report the fabrication, by a three-step high temperature decomposition method, of Fe3O4/MgO/CoFe2O4 onio-like nanoparticles and their detailed structural analysis, elemental compositional maps and magnetic response. The core/shell/shell nanoparticles present epitaxial growth and cubic shape with overall size of (29+-6) nm. These nanoparticles are formed by cubic iron oxide core of (22+-4) nm covered by two shells, the inner of magnesium oxide and the outer of cobalt ferrite of ~1 and ~2.5 nm of thickness, respectively. The magnetization measurements show a single reversion magnetization curve and the enhancement of the coercivity field, from HC~608 Oe for the Fe3O4/MgO to HC~5890 Oe to the Fe3O4/MgO/CoFe2O4 nanoparticles at T=5 K, ascribed to the coupling between both ferrimagnetic phases with a coupling constant of =2 erg/cm2. The system also exhibits exchange bias effect, where the exchange bias field increases up to HEB~2850 Oe at 5 K accompanied with the broadening of the magnetization loop of HC~6650 Oe. This exchange bias effect originates from the freezing of the surface spins below the freezing temperature TF=32 K that pinned the magnetic moment of the cobalt ferrite shell.

description: We present an efficient algorithm for computing the LZ78 factorization of a text, where the text is represented as a straight line program (SLP), which is a context free grammar in the Chomsky normal form that generates a single string. Given an SLP of size $n$ representing a text $S$ of length $N$, our algorithm computes the LZ78 factorization of $T$ in $O(n\sqrt{N}+m\log N)$ time and $O(n\sqrt{N}+m)$ space, where $m$ is the number of resulting LZ78 factors. We also show how to improve the algorithm so that the $n\sqrt{N}$ term in the time and space complexities becomes either $nL$, where $L$ is the length of the longest LZ78 factor, or $(N - α)$ where $α\geq 0$ is a quantity which depends on the amount of redundancy that the SLP captures with respect to substrings of $S$ of a certain length. Since $m = O(N/\log_σN)$ where $σ$ is the alphabet size, the latter is asymptotically at least as fast as a linear time algorithm which runs on the uncompressed string when $σ$ is constant, and can be more efficient when the text is compressible, i.e. when $m$ and $n$ are small.

description: Las personas trabajan formando parte de la organización. Estas, en el desarrollo de este trabajo tienen sus motivaciones, afrontan las coyunturas agradables y los inconvenientes o insatisfacciones que el mismo le depara, se relacionan con sus compañeros o colegas formando grupos, etc. Todo esto se traduce en un comportamiento, ya sea individual o grupal, en pos de sus propios fines y los objetivos de la organización. El objetivo de esta investigación fue determinar qué relación existe entre el nivel de recordación del plan de evacuación que tiene el personal con respecto a los que recibieron sólo capacitación de los que recibieron tanto capacitación como simulacro de evacuación ante emergencias, en el Hogar Elías Romero, Hospital Español Anexo Temperley, en mayo de 2017. Se realizó un estudio descriptivo, trasversal. Las unidades de análisis son cada una de las personas que recibió capacitación sobre evacuación y/o simulacro ante emergencia, que se desempeñaron en la Residencia Geriátrica “Hogar Elías Romero” durante el período de mayo del 2017. Aquellas unidades que por algún motivo no respondan la encuesta (por negación, ausentismo, vacaciones, licencia, u otro), serán considerados datos perdidos (criterios de exclusión). Del personal encuestado podemos ver que casi la mitad es un no profesional con atención directa al paciente/residente (43%), mientras en menor nivel es un no profesional, pero sin dicha atención directa (33%). Por último, los profesionales con atención directa al paciente/residente
 son la menor cantidad de encuestados (24%). Luego de analizar los resultados obtenidos se sabe que, con respecto a las preguntas de la presente investigación, el nivel de recordación acerca del procedimiento de evacuación ante emergencias quedó comprobado en relación a las variables capacitación teórica y práctica ante emergencias. El nivel de nivel de recordación que tiene el personal es “recordación media”. Siendo la “recordación media” más alta en el personal que recibió capacitación con simulacro de evacuación ante emergencias.

description: We investigate the excitation of magnetoacoustic-gravity waves generated from localized pulses in the gas pressure as well as in vertical component of velocity. These pulses are initially launched at the top of the solar photosphere that is permeated by a weak magnetic field. We investigate three different configurations of the background magnetic field lines: horizontal, vertical and oblique to the gravitational force. We numerically model magnetoacoustic-gravity waves by implementing a realistic (VAL-C) model of solar temperature. We solve two-dimensional ideal magnetohydrodynamic equations numerically with the use of the FLASH code to simulate the dynamics of the lower solar atmosphere. The initial pulses result in shocks at higher altitudes. Our numerical simulations reveal that a small-amplitude initial pulse can produce magnetoacoustic-gravity waves, which are later reflected from the transition region due to the large temperature gradient. The atmospheric cavities in the lower solar atmosphere are found to be the ideal places that may act as a resonator for various oscillations, including their trapping and leakage into the higher atmosphere. Our numerical simulations successfully model the excitation of such wave modes, their reflection and trapping, as well as the associated plasma dynamics.

description: We study a class of systems of quasilinear differential inequalities associated to weakly coercive differential operators and power reaction terms. The main model cases are given by the $p$-Laplacian operator as well as the mean curvature operator in non parametric form. We prove that if the exponents lie under a certain curve, then the system has only the trivial solution. These results hold without any restriction provided the possible solutions are more regular. The underlying framework is the classical Euclidean case as well as the Carnot groups setting.

description: We calculate the quark coefficient function Tq(x,xi) that enters the factorized amplitude for deeply virtual Compton scattering (DVCS) at all order in a soft and collinear gluon approximation, focusing on the leading double logarithmic behavior in x +/- xi, where x +/- xi is the light cone momentum fraction of the incoming/outgoing quarks. We show that the dominant part of the known one loop result can be understood in an axial gauge as the result of a semi-eikonal approximation to the box diagram. We then derive an all order result for the leading contribution of the ladder diagrams and deduce a resummation formula valid in the vicinity of the boundaries of the regions defining the energy flows of the incoming/outcoming quarks, i.e. x = +/- xi. The resummed series results in a simple closed expression.

description: This research project utilizes Chicago’s Chinatown neighborhood as a case study for the ways in which the built environment can sustain conflicting and at times contested meanings that create distinctive patterns of community identity formation at the level of street block or building. Ultimately, the ways in which Chinatown’s community negotiates and finds balance in urban spaces that serve both performative and interpersonal ends proves to be an essential element of Chinese-American community and boundary maintenance across physical, generational, and cultural lines.
