description: The recent survey of the core-collapse supernova remnant Cassiopeia A (CasA) with the MIRI instrument on board the James Webb Space Telescope (JWST) revealed a large structure in the interior region, referred to as the "Green Monster". Although its location suggests that it is an ejecta structure, the infrared properties of the "Green Monster" hint at a circumstellar medium (CSM) origin. In this companion paper to the JWST Cas A paper, we investigate the filamentary X-ray structures associated with the "Green Monster" using Chandra X-ray Observatory data. We extracted spectra along the "Green Monster" as well as from shocked CSM regions. Both the extracted spectra and a principal component analysis show that the "Green Monster" emission properties are similar to those of the shocked CSM. The spectra are well-fit by a model consisting of a combination of a non-equilibrium-ionization model and a power-law component, modified by Galactic absorption. All the "Green Monster" spectra show a blueshift corresponding to a radial velocity of around -2300 km/s, suggesting that the structure is on the near side of Cas A. The ionization age is around $n_{e}t = 1.5 \times 10^{11}$ cm$^{-3}s. This translates into a pre-shock density of ~12 cm$^{-3}$, higher than previous estimates of the unshocked CSM. The relatively high net and relatively low radial velocity suggest that this structure has a relatively high density compared to other shocked CSM plasma. This analysis provides yet another piece of evidence that the CSM around Cas A's progenitor was not that of a smooth steady wind profile.

description: Very recently, we proposed an explanation of the discrepancy between the measured anomalous magnetic moment of the muon and the Standard Model (SM) prediction in which the dominant contribution to $(g-2)_μ$ originates in Kaluza-Klein (KK) excitations (of the lepton gauge boson) which do not mix with quarks (to lowest order) and therefore can be quite light avoiding LHC constraints. In this addendum we reexamine the bounds on 4-fermion contact interactions from precise electroweak measurements and show that the constraints on KK masses and couplings are more severe than earlier thought. However, we demonstrate that our explanation remains plausible if a few KK modes are lighter than LEP energy, because if this were the case the contribution to the 4-fermion scattering from the internal propagator would be dominated by the energy and not by the mass. To accommodate the $(g-2)_μ$ discrepancy we assume that the lepton number $L$ does not partake in the hypercharge and propagates in one extra dimension (transverse to the SM branes): for a mass of the lowest KK excitation of 60 GeV (lower than the LEP energy), the string scale is roughly 10 TeV while the $L$ gauge coupling is of order $\sim 10^{-1}$.

description: We present a novel $\mathcal{N} = 2 $ $\mathbb{Z}_2^2$-graded supersymmetric quantum mechanics ($\mathbb{Z}_2^2$-SQM) which has different features from those introduced so far. It is a two-dimensional (two-particle) system and is the first example of the quantum mechanical realization of an eight-dimensional irrep of the $\mathcal{N}=2$ $\mathbb{Z}_2^2$-supersymmetry algebra. The $\mathbb{Z}_2^2$-SQM is obtained by quantizing the one-dimensional classical system derived by dimensional reduction from the two-dimensional $\mathbb{Z}_2^2$-supersymmetric Lagrangian of $\mathcal{N}=1$, which we constructed in our previous work. The ground states of the $\mathbb{Z}_2^2$-SQM are also investigated.

description: We present multi-epoch, multi-colour pre-outburst photometry and post-outburst light curves and spectra of the luminous blue variable (LBV) outburst Gaia16cfr discovered by the Gaia satellite on 1 December 2016. We detect Gaia16cfr in 13 epochs of Hubble Space Telescope imaging spanning phases of 10 yr to 8 months before the outburst and in Spitzer Space Telescope imaging 13 years before outburst. Pre-outburst optical photometry is consistent with an 18 Msun F8 I star, although the star was likely reddened and closer to 30 Msun. The pre-outburst source exhibited a significant near-infrared excess consistent with a 120 AU shell with 4x10-6 Msun of dust. We infer that the source was enshrouded by an optically-thick and compact shell of circumstellar material from an LBV wind, which formed a pseudo-photosphere consistent with S Dor-like variables in their "maximum" phase. Within a year of outburst, the source was highly variable on 10-30 day timescales. The outburst light curve closely matches that of the 2012 outburst of SN 2009ip, although the observed velocities are significantly slower than in that event. In Halpha, the outburst had an excess of blueshifted emission at late times centred around -1500 km/s, similar to that of double-peaked Type IIn supernovae and the LBV outburst SN 2015bh. From the pre-outburst and post-outburst photometry, we infer that the outburst ejecta are evolving into a dense, highly structured circumstellar environment from precursor outbursts within years of the December 2016 event.

description: This paper studies the influence of bending deflections on the structural behaviour of masonry columns. Some explicit solutions are presented, and the combined effects of the constitutive and geometric nonlinearities are investigated through an iterative numerical procedure. The results show that considering second-order effects affects both the collapse load and the dynamical properties of masonry beams significantly.
title: Untersuchung der Bauteilhaftung in der Fused Filament Fabrication
Creators: name: Laumann, Daniel
Publisher: name: UNSPECIFIED

description: Fused Filament Fabrication (FFF) spielt eine immer wichtigere Rolle in der Industrie und ist mittlerweile in zahlreichen Branchen ein etabliertes Verfahren. Dennoch treten vor allem bei der Verarbeitung von Hochleistungspolymeren immer noch Prozessfehler wie ein ungewolltes Ablösen des zu fertigenden Bauteils von der Bauplattform auf. Solche Prozessfehler werden durch eine mangelnde Adhäsion zwischen Bauteil und Bauplattform verursacht. Obwohl Adhäsion eine zentrale Bedeutung im FFF-Prozess spielt, erfolgte bisher kaum eine wissenschaftliche Betrachtung dieses Aspekts. Aus diesem Grund werden in der vorliegenden
Dissertation grundlegende Zusammenhänge im FFF-Prozess untersucht. Um die auftretenden Adhäsionskräfte quantifizieren zu können wurde zuerst ein auf DIN EN 28510-1 basierendes Messverfahren entwickelt und ein entsprechender Prüfstand aufgebaut. Mit diesem Messverfahren wurden verschiedene Parameter identifiziert, die die Adhäsion im FFF-Prozess beeinflussen. Dazu zählt das Material der Bauplattform, die Verarbeitungstemperaturen, die Druckgeschwindigkeit sowie die Dicke der ersten Schicht, der Feuchtegehalt des Druckmaterials und die Kontaktzeit. Zwischen diesen Einflussgrößen bestehen Wechselwirkungen. Dies bedeutet, dass das Verändern einer Größe den Zusammenhang zwischen der Bauteiladhäsion und einer zweiten Größe ändert. So kann eine Steigerung der Düsentemperatur um 40 °C eine Änderung der gemessenen Adhäsionskraft um rund 100 N bewirken. Wird die selbe Messreihe aber auf einem anderen Bauplattformmaterial oder bei einer anderen Düsentemperatur wiederholt, zeigt eine Steigerung der Düsentemperatur praktisch keine Wirkung mehr. Das Identifizieren und
Charakterisieren solcher Wechselwirkungen zwischen den oben aufgelisteten Einflussgrößen ist ebenfalls Gegenstand dieser Arbeit. Die Kenntnisse, welche Prozessparameter eine Rolle spielen und wie diese miteinander zusammenhängen, werden zu einer Klassifizierung und einem Ranking zusammengeführt. Dies erlaubt Anwendern eine gezielte Verbesserung der Prozessparameter im Falle einer zu geringen Adhäsion. Durch die gewonnenen Erkenntnisse können auch Rückschlüsse auf die wirkenden Adhäsionsmechanismen gezogen werden: Für die Adhäsion zwischen Borosilikatglas und Pertinax als Bauplattformmaterial und dem verdruckten Material wird vorgeschlagen, dass Wasserstoffbrückenbindungen eine zentrale Rolle spielen. Wird hingegen Messing als Bauplattformmaterial genutzt, deuten die Ergebnisse dieser Dissertation auf eine Ionenbindung hin. Diese entsteht nach einer chemischen Reaktion der auf der Messingoberfläche befindlichen Oxide und funktionellen Gruppen des zu verdruckenden Kunststoffs. Mit diesen neuen Erkenntnissen können Anwender nun je nach zu verdruckendem Material eine optimales Bauplattformmaterial auswählen ohne zuvor die Eignung in Parameterstudien untersuchen zu müssen.

description: We introduce a new and highly efficient tagger for hadronically decaying top quarks, based on a deep neural network working with Lorentz vectors and the Minkowski metric. With its novel machine learning setup and architecture it allows us to identify boosted top quarks not only from calorimeter towers, but also including tracking information. We show how the performance of our tagger compares with QCD-inspired and image-recognition approaches and find that it significantly increases the performance for strongly boosted top quarks.

description: The advantage of an ultra-fast frequency-tunability of spin-torque nano-oscillators (STNOs) that have large (> 100MHz) relaxation frequency of amplitude fluctuations is exploited to realize ultra-fast wide-band time-resolved spectral analysis at nanosecond time scale with the frequency resolution limited only by the 'bandwidth' theorem. The demonstration is performed with an STNO generating in the 9 GHz frequency range, and comprised of a perpendicular polarizer and a perpendicularly and uniformly magnetized 'free' layer. It is shown that such a uniform-state STNO-based spectrum analyzer can efficiently perform spectral analysis of frequency-agile signals with rapidly varying frequency components.
Perceptual biases in the interpretation of non-rigid structure from motion
Creators: name: Choi, Ryne
Publisher: name: No Publisher Supplied
Year: 2020

description: While structure-from-motion (SFM) studies have largely focused on the perception of rigidly moving 3D objects, recent studies have shown that observers are good at perceiving certain kinds of non-rigid transformations parencite{Jain2011}. Our overarching goal is to understand what types of non-rigid transformations are perceivable in SFM. As a first step towards this goal, this study investigates the role of biological plausibility of shape transformations.Experiment 1 compared the perception of two non-rigid transformations: part-orientation change (which is more common in animate motion, e.g. part-wise articulation of limbs) and part-length change (which is less common). Stimuli consisted of an ellipsoid with a protruding part that underwent a non-rigid length change as the whole object rotated back and forth. We manipulated the extent of length change and subjects judged whether the part was undergoing a length or orientation change. In this experiment, the image of the part was always contained within the silhouette of the ellipsoid. Results showed a clear range where length change was misperceived as orientation change.Experiment 2 further investigated the misperception of non-rigid length change. The part was now visible in the silhouette. We observed a misperception of non-rigid length change as a rigidly-attached part with an "illusory" non-orthogonal horizontal angle relative to the ellipsoid. Observers adjusted the perceived angle between the part and the ellipsoid. We then compared the perceived horizontal angle to model predictions based on a reinterpretation of the length change in terms of a fixed horizontal angle between the part and the main body, with no length change. Even with no free parameters, the model closely tracked observers’ data.In summary, an SFM stimulus in which a part undergoes a length change, tends to be misperceived either as an orientation change (Exp. 1), or as a fixed but "illusory" orientation (Exp. 2). The results suggest that the visual system may be biased towards more biologically plausible interpretations of non-rigid motion.

In this way we manage to introduce the first finite Hilbert-style single-conclusion axiomatizations for these logics.

description: We report observation of sub-Doppler cooling of lithium using an irregular-tetrahedral laser beam arrangement, which is produced by a nanofabricated diffraction grating. We are able to capture 11(2) % of the lithium atoms from a grating magneto-optical trap into $Λ$-enhanced $D_1$ gray molasses. The molasses cools the captured atoms to a radial temperature of 60(9) $μ$K and an axial temperature of 23(3) $μ$K. In contrast to results from conventional counterpropagating beam configurations, we do not observe cooling when our optical fields are detuned from Raman resonance. An optical Bloch equation simulation of the cooling dynamics agrees with our data. Our results show that grating magneto-optical traps can serve as a robust source of cold atoms for tweezer-array and atom-chip experiments, even when the atomic species is not amenable to sub-Doppler cooling in bright optical molasses.

description: In this paper, we consider the asymptotical regularization with convex constraints for nonlinear ill-posed problems. The method allows to use non-smooth penalty terms, including the L1-like and the total variation-like penalty functionals, which are significant in reconstructing special features of solutions such as sparsity and piecewise constancy. Under certain conditions we give convergence properties of the methods. Moreover, we propose Runge-Kutta type methods to discrete the initial value problems to construct new type iterative regularization methods.

Nessa perspectiva, por mais que o Estatuto da Criança e do Adolescente (ECA) disserte sobre a responsabilidade do poder público (BRASIL, 1990), as instituições que deveriam propiciar condições adequadas de reclusão ainda fomentam a negligência destes. Atentar para a realidade esboçada na pesquisa realizada pela Secretaria de Assuntos Legislativos do Ministério da Justiça no projeto “Dar à luz na sombra” é mister para a resolução de impasses que fragmentam a dignidade de sujeitos de Direito. Por tal ângulo, consta que especificamente nas unidades femininas, encontramos maiores violações no tangente ao exercício de direitos de forma geral, e em especial dos direitos sexuais e reprodutivos (BRASIL, 2015, p.17).

description: A disformal rotating black-hole solution is a black-hole solution in quadratic degenerate higher-order scalar-tensor theories. It breaks the circular condition of spacetime different from the case of the usual Kerr spacetime. This study investigated the dynamic behaviors of the motion of timelike particles in such disformal black-hole spacetime with an extra deformation parameter. Results showed that the characteristics of the particle's motion depend on the sign of the deformation parameter. For the positive deformation parameter, the motion is regular and orderly. For the negative one, as the deformation parameter changes, the motion of the particles undergoes a series of transitions between the chaotic motion and the regular motion and falls into the horizon or escapes to spatial infinity. This means that the dynamic behavior of timelike particles in the disformal Kerr black-hole spacetime with noncircularity becomes richer than that in the usual Kerr black-hole case.

description: TWA 27B (2M1207b) is the first directly-imaged planetary-mass (MP ~ 5 MJ) companion (Chauvin et al. 2004) and was observed at 0.9--5.3 micron with JWST/NIRSpec (Luhman et al. 2023). To understand the accretion properties of TWA 27B, we search for continuum-subtracted near-infrared helium and hydrogen emission lines and measure their widths and luminosities. We detect the He I triplet at 4.3 sigma and all Paschen-series lines covered by NIRSpec (Pa alpha, Pa beta, Pa gamma, Pa delta) at 4--5 sigma. The three brightest Brackett-series lines (Br alpha, Br beta, Br gamma) as well as Pf gamma and Pf delta are tentative detections at 2--3 sigma. We provide upper limits on the other hydrogen lines, including on H alpha through Hubble Space Telescope archival data. Three lines can be reliably deconvolved to reveal an intrinsic width Delta v = 67+-9 km/s, which is 60% of the surface freefall velocity. The line luminosities seem significantly too high to be due to chromospheric activity. Converting line luminosities to an accretion rate yields Mdot ~ 5e-9 MJ/yr when using scaling relationships for planetary masses, and Mdot ~ 0.1e-9 MJ/yr with extrapolated stellar scalings. Several of these lines represent first detections at an accretor of such low mass. The weak accretion rate implies that formation is likely over. This analysis shows that JWST can be used to measure low line-emitting mass accretion rates onto planetary-mass objects, motivates deeper searches for the mass reservoir feeding TWA 27B, and hints that other young directly-imaged objects might -- hitherto unbeknownst -- also be accreting.

description: Quasicrystal is a class of ordered structures defying conventional classification of solid crystals and may carry classically forbidden (e.g., 5-fold) rotational symmetries. In view of long-sought supersolids, a natural question is whether a superfluid can spontaneously form quasicrystalline order that is not possessed by the underlying Hamiltonian, forming "superfluid-quasicrystals". Here we show that a superfluid-quasicrystal stripe state with the minimal 5-fold rotational symmetry can be realized as the ground state of a Bose-Einstein condensate within a practical experimental scheme. There exists a rich phase diagram consisting of various superfluid-quasicrystal, supersolid, and plane-wave phases. Our scheme can be generalized for generating other higher-order (e.g., 7-fold) quasicrystal states, and provides a platform for investigating such new exotic quantum matter.

Como objetivos específicos: a) analisar as práticas do Uruguai após a legalização do aborto; b) verificar o auxílio dado às mulheres que desejam abortar no Uruguai; c) constatar a eficácia do programa de legalização do aborto no Uruguai; d) levantar os números de aborto antes e depois da implantação do programa; e) analisar o que levou a legalização do aborto no Uruguai; f) analisar o apoio dado pelo estado à mulher que desejar prosseguir ou não com o aborto; g) verificar como a cultura e a religião reagiram à legalização do aborto; h) analisar quais foram às mudanças na estrutura dentro do Estado Uruguaio para a implantação da legalização. O presente projeto de pesquisa se faz necessário para o Brasil devido o aborto ser o quinto maior causador de mortes maternas, segundo Conselho Federal de Medicina (MARQUEZ, 2013) no Brasil a lei 2848/40 art.128 do código penal (BRASIL, 1940) criminaliza o aborto com exceções aos casos que a gestação representa risco de vida a mulher, quando a gestação resulta de estupro e quando o feto é anencefálo. Por conta da lei restringir o método de abortar, esse número de mortalidade materna se faz tão grande não tendo o aparato ideal, tanto físico quanto psicológico dado às mulheres de forma médica, elas recorrem a meios ilegais, trazendo sérios riscos a sua saúde, levando na maioria das vezes a morte.

description: The progenitor systems of the class of "Ca-rich transients" is a key open issue in time domain astrophysics. These intriguing objects exhibit unusually strong calcium line emissions months after explosion, fall within an intermediate luminosity range, are often found at large projected distances from their host galaxies, and may play a vital role in enriching galaxies and the intergalactic medium. Here we present multi-wavelength observations of iPTF15eqv in NGC 3430, which exhibits a unique combination of properties that bridge those observed in Ca-rich transients and Type Ib/c supernovae. iPTF15eqv has among the highest [Ca II]/[O I] emission line ratios observed to date, yet is more luminous and decays more slowly than other Ca-rich transients. Optical and near-infrared photometry and spectroscopy reveal signatures consistent with the supernova explosion of a < 10 solar mass star that was stripped of its H-rich envelope via binary interaction. Distinct chemical abundances and ejecta kinematics suggest that the core collapse occurred through electron capture processes. Deep limits on possible radio emission made with the Jansky Very Large Array imply a clean environment ($n 100 solar masses). Our results challenge the notion that spectroscopically classified Ca-rich transients only originate from white dwarf progenitor systems, complicate the view that they are all associated with large ejection velocities, and indicate that their chemical abundances may vary widely between events.

description: Diffraction in time manifests itself as the appearance of probability-density fringes when a matter wave passes through an opaque screen with abrupt temporal variations of transmission properties. Here we analytically describe the phase-space structure of diffraction-in-time fringes for a class of smooth time gratings. More precisely, we obtain an analytic expression for the Husimi distribution representing the state of the system in the case of time gratings comprising a succession of Lorentzian-like slits. In particular, for a double-slit scenario, we derive a simple and intuitive expression that accurately captures the position of interference fringes in phase space.

description: Many complex systems are modular. Such systems can be represented as "component systems", i.e., sets of elementary components, such as LEGO bricks in LEGO sets. The bricks found in a LEGO set reflect a target architecture, which can be built following a set-specific list of instructions. In other component systems, instead, the underlying functional design and constraints are not obvious a priori, and their detection is often a challenge of both scientific and practical importance, requiring a clear understanding of component statistics. Importantly, some quantitative invariants appear to be common to many component systems, most notably a common broad distribution of component abundances, which often resembles the well-known Zipf's law. Such "laws" affect in a general and non-trivial way the component statistics, potentially hindering the identification of system-specific functional constraints or generative processes. Here, we specifically focus on the statistics of shared components, i.e., the distribution of the number of components shared by different system-realizations, such as the common bricks found in different LEGO sets. To account for the effects of component heterogeneity, we consider a simple null model, which builds system-realizations by random draws from a universe of possible components. Under general assumptions on abundance heterogeneity, we provide analytical estimates of component occurrence, which quantify exhaustively the statistics of shared components. Surprisingly, this simple null model can positively explain important features of empirical component-occurrence distributions obtained from data on bacterial genomes, LEGO sets, and book chapters. Specific architectural features and functional constraints can be detected from occurrence patterns as deviations from these null predictions, as we show for the illustrative case of the "core" genome in bacteria.

description: Constata-se como objetivo geral do trabalho a análise da implementação das cotas universitárias em Belo Horizonte e a verificação de seus possíveis impactos sociais e educacionais. São objetivos específicos: a) analisar a necessidade de implementação das cotas universitárias; b) verificar suas consequências, tanto para o estudante, quanto para a sociedade; c) levantar dados que corroborem a eficácia da implementação das cotas; d) reunir opiniões acerca do tema; e) analisar como essa política afeta o mercado de trabalho. Pode-se afirmar que o quadro histórico segregacionista brasileiro e a recente estrutura educacional pública não possibilitam uma igualdade entre todos os estudantes do Brasil. Diante disso, é notória a necessidade da Lei de Cotas e de discussões acerca do tema com o objetivo de fomentar o ingresso de jovens negros e jovens carentes no ensino superior. Pois, modificando o perfil das universidades, pode-se também amenizar a profunda desigualdade social que caracteriza o Brasil. Essa ideia é corroborada por Nery Junior que diz que dar tratamento isonômico às partes significa tratar igualmente os iguais e desigualmente os desiguais, na exata medida de suas desigualdades (ASSOCIAÇÃO NACIONAL DOS ANALISTAS JURÍDICOS). Assim como Emiliano que classifica as políticas de ação afirmativa como iniciativas que visam favorecer grupos ou segmentos socialmente inferiorizados (SOUZA, 2016).

description: We present a generalised time scale for quantum chaos dynamics, motivated by nonextensive statistical mechanics. It recovers, as particular cases, the relaxation (Heisenberg) and the random (Ehrenfest) time scales. Moreover, we show that the generalised time scale can also be obtained from a nonextensive version of the Kolmogorov-Sinai entropy by considering the graininess of quantum phase space and a generalised uncorrelation between subsets of the phase space. Lyapunov and regular regimes for the fidelity decay are obtained as a consequence of a nonextensive generalisation of the $m$th point correlation function for a uniformly distributed perturbation in the classical limit.

description: We propose an improved twist-averaging scheme for quantum Monte Carlo methods that use converged Kohn-Sham or Hartree-Fock orbitals as the reference. This twist-averaging technique is tailored to sample the Brillouin zone of magnetic metals, although it naturally extends to nonmagnetic conducting systems. The proposed scheme aims to reproduce the reference magnetization and achieves charge neutrality by construction, thus avoiding the large energy fluctuations and the postprocessing needed to correct the energies. It shows the most robust convergence of total energy and magnetism to the thermodynamic limit when compared to four other twist-averaging schemes. Diffusion Monte Carlo applications are shown on nonmagnetic Al and ferromagnetic $α$-Fe. The cohesive energy of Al in the thermodynamic limit shows an excellent agreement with the experimental result. Furthermore, the magnetic moments in $α$-Fe exhibit rapid convergence with an increasing number of twists.

description: The finite temperature version of the Vashishta-Singwi (VS) dielectric scheme for the paramagnetic warm dense uniform electron fluid is revisited correcting for an earlier thermodynamic derivative error. The VS scheme handles quantum mechanical effects at the level of the random phase approximation and treats correlations via the density expansion of a generalized Singwi-Tosi-Land-Sjölander (STLS) closure that inserts a parameter determined by enforcing the compressibility sum rule. Systematic comparison with quasi-exact results, based on quantum Monte Carlo simulations, reveals a structural superiority of the VS scheme towards strong coupling and a thermodynamic superiority of the STLS scheme courtesy of a favorable cancellation of errors. Guidelines are provided for the construction of dielectric schemes that are expected to be more accurate but computationally costly.

description: We establish that boundary degrees of freedom associated with a generic co-dimension one null surface in $D$ dimensional pure Einstein gravity naturally admit a thermodynamical description. We expect the $\textit{null surface thermodynamics}$ to universally follow as a result of the diffeomorphism invariance of the theory, not relying on other special features of the null surface or the gravity theory. Using standard surface charge analysis and covariant phase space method, we formulate laws of null surface thermodynamics which are local equations over an arbitrary null surface paralleling local versions the zeroth and first laws and the Gibbs-Duhem equation. This thermodynamical system is generally an open system and can be closed only when there is no flux of gravitons through the null surface. Our analysis extends the usual black hole thermodynamics to a universal feature of any area element on a generic null surface. We discuss the relevance of our study for the membrane paradigm and black hole microstates.
