description: Asymmetric features in exoplanet transit light curves are often interpreted as a gravity darkening effect especially if there is spectroscopic evidence of a spin-orbit misalignment. Since other processes can also lead to light curve asymmetries this may lead to inaccurate gravity darkening parameters. Here we investigate the case of non-radial pulsations as possible sources of asymmetry and likely source of misinterpreted parameters through simulations. We obtained a series of simulated transit light curves of a hypothetical exoplanet-star system: a host star with no gravity darkening exhibiting small amplitude pulsations, and a typical hot Jupiter in a circular, edge-on orbit. A number of scenarios of pulsations of various amplitudes were considered, and a proper account of the obscuring effect of transits on all the surface intensity components was made. The magnitude of amplitude and phase modulations of nonradial pulsations during transits was also also investigated. We then fitted both a non-gravity-darkened, and a gravity-darkened, free spin-orbit axis model on the data. The Akaike and Bayesian Information Criteria were used for an objective selection of the most plausible model. We then explored the dependence of the parameter deviations on the pulsation properties, in order to identify configurations that can lead to falsely misaligned solutions. Low-amplitude pulsations in general do not affect the determination of the system parameters beyond their noise nature. However, frequencies close to multiples of the orbital frequency are found to cause distortions leading to solutions with a side tilted stellar rotational axis, they are therefore preferable to clean beforehand for the sake of a correct analysis. Additionally, for cases with higher-amplitude pulsations, it is recommended to pre-process and clean the pulsations before analysis.

description: In this paper we study motivic amplitudes--objects which contain all of the essential mathematical content of scattering amplitudes in planar SYM theory in a completely canonical way, free from the ambiguities inherent in any attempt to choose particular functional representatives. We find that the cluster structure on the kinematic configuration space Conf_n(P^3) underlies the structure of motivic amplitudes. Specifically, we compute explicitly the coproduct of the two-loop seven-particle MHV motivic amplitude A_{7,2} and find that like the previously known six-particle amplitude, it depends only on certain preferred coordinates known in the mathematics literature as cluster X-coordinates on Conf_n(P^3). We also find intriguing relations between motivic amplitudes and the geometry of generalized associahedrons, to which cluster coordinates have a natural combinatoric connection. For example, the obstruction to A_{7,2} being expressible in terms of classical polylogarithms is most naturally represented by certain quadrilateral faces of the appropriate associahedron. We also find and prove the first known functional equation for the trilogarithm in which all 40 arguments are cluster X-coordinates of a single algebra. In this respect it is similar to Abel's 5-term dilogarithm identity.

title: Elaboración, variación y selección en el paradigma de los adverbios de exactitud El caso de al justo y al cabal
Creators: name: Gerhalter, Katharina
Publisher: name: University of Graz
Year: 2020

description: La locución adverbial al justo surge durante el siglo XVI como expresión sinónima del adverbio corto justo tanto en función de adverbio de modo como en función de adverbio de foco. Su creación está ligada a la elaboración de la lengua escrita, y se atestigua específicamente en tratados científicos y técnicos. El esquema [preposición a + artículo + adjetivo de exactitud] es productivo con adjetivos hereditarios y popularizados, ya que desde justo se extiende a cabal (al cabal), pero no a los adjetivos cultos preciso y exacto. Tras el auge de estas locuciones adverbiales hacia finales del siglo XVI, al justo y al cabal caen en desuso en la segunda mitad del siglo siguiente. Su marginalización se encuentra ligada a la competición y selección entre las diversas variantes que forman el paradigma de los adverbios de exactitud. Al justo, que era la variante más frecuente hasta mediados del siglo XVII, acaba siendo desplazada por justamente. A su vez, el contraste con el francés au juste muestra que, a partir de un panorama inicial parecido, la selección entre variantes puede dar resultados divergentes en lenguas distintas.
description: The adverbial al justo originated during the 16th century as a synonym for the short adverb justo. It was used as manner adverbial as well as focus adverb. Its creation was closely connected to the elaboration of written language, e.g. in scientific or technical texts. The pattern [preposition a + article + adjective expressing exactness] was productive with inherited adjectives or those which entered the popular tradition. In the specific case of al justo, it expanded to the former synonym cabal (al cabal), but not to the learned adjectives preciso or exacto. After a short upward trend at the end of the 16th century, the frequency of al justo and al cabal fell during the second half of the 17th century. The marginalization of these adverbials was caused by the competition and selection between several variants forming the paradigm of exactness-adverbs. Al justo, the most frequent variant until the middle of the 17th century, was replaced by justamente. The contrast with French au juste shows that the selection between variants can lead to diverging developments in different languages despite similar initial conditions.

description: We propose a modeling framework for growing multiplexes where a node can belong to different networks. We define new measures for multiplexes and we identify a number of relevant ingredients for modeling their evolution such as the coupling between the different layers and the arrival time distribution of nodes. The topology of the multiplex changes significantly in the different cases under consideration, with effects of the arrival time of nodes on the degree distribution, average shortest paths and interdependence.

description: Astrophysical events that occur in active galactic nucleus (AGN) disks are believed to differ significantly from the ordinary in the interstellar medium. We show that stars located in the outer region of the AGN disk would explode near the original migration starting points instead of being accreted by the central supermassive black hole due to the effect of viscosity. AGN disks provide a dense environment for supernova (SN) explosions, which inevitably involve ejecta-disk interactions. In this paper, we investigate the light curves (LCs) of core-collapse SN exploded in AGN disks. In addition to the fundamental energy source of $^{56} \mathrm{Ni}$--$^{56} \mathrm{Co}$--$^{56} \mathrm{Fe}$ decay reaction powering the SN LCs, the forward-reverse shock produced during interactions may contribute significantly to the observed flux. If the stellar winds manage to create a cavity surrounded by a shell near the star before the SN explosion, the ejecta-winds-disk configurations are expected. We present various SN LCs from different types of progenitors and find that the SN LCs are dominated by the radiation of ejecta-disk interaction-induced shocks. The resulting SNe in the AGN disk is a promising transient source for UV and optical band detection by the Neil Gehrels Swift Observatory (Swift), the Ultraviolet Explorer (UVEX) and wide field survey telescopes such as Ultraviolet Transient Astronomy Satellite (ULTRASAT), Wide Field Survey Telescope (WFST) and Legacy Survey of Space and Time (LSST) at the Vera C. Rubin Observatory. These detections could aid in the investigation of AGN discs and the associated high-energy transient occurrences.

description: Context. In 2020, a publication presented the first-light results for 18 known ZZ Ceti stars observed by the TESS space telescope during the first survey observations of the southern ecliptic hemisphere. However, in the meantime, new measurements have become available from this field, in many cases with the new, 20s ultrashort cadence mode. Aims. We investigated the similarities and differences in the pulsational behaviour of the observed stars between the two observational seasons, and searched for new pulsation modes for asteroseismology. Methods. We performed Fourier analysis of the light curves using the standard pre-whitening process, and compared the results with frequencies obtained from the earlier data. Utilising the 2018 version of the White Dwarf Evolution Code, we also performed an asteroseismic analysis of the different stars. We searched for models with seismic distances in the vicinity of the Gaia geometric distances. Results. We detected several new possible pulsation modes of the studied pulsators. In the case of HE 0532-5605, we found a similar brightening phase to the one presented in the 2020 first-light paper, which means this phenomenon is recurring. Therefore, HE 0532-5605 appears to be a new outbursting DAV star. We also detected a lower-amplitude brightening phase in the star WD J0925+0509. However, this case has proven to be the result of the passage of a Solar System object in the foreground. We accept asteroseismic model solutions for six stars.

description: In a climate where teachers feel deprofessionalized at the hands of regulations, testing, and politics, it is vital that teachers become empowered both in their own teaching and as agents of change. This physics education research study investigates the Streamline to Mastery professional development program, in which the teachers design professional development opportunities for themselves and for fellow teachers. The research reported here describes the process of teacher professional growth through changes in roles and identities. Videos, emails, and interviews were analyzed to glean insight into practice and participation shifts as these physical science teachers formed a community and engaged in their own classroom research. Implications for the role of PER in teacher professional development and teacher preparation will be discussed.

description: O Curso Superior de Graduação em Licenciatura em Química, na área do conhecimento em Ensino de Ciências e Matemática, no Campus Duque de Caxias do Instituto Federal de Educação Ciência e Tecnologia do Rio de Janeiro- IFRJ tem como proposta formar um professor crítico e reflexivo através da geração de conhecimentos científicos e pedagógicos em todo percurso do curso. Embora o Projeto Pedagógico do Curso tenha uma proposta atraente, a evasão e a retenção tem sido alarmantes. Os Indicadores Acadêmicos na Trajetória de Realização do ciclo (2013.1 – 2016.2) apresentam que a evasão e a permanência em 2016.2 eram de 45,4% e 26,19 respectivamente. Esta pesquisa tem o objetivo de identificar os fatores determinantes da evasão e da permanência nos ciclos (2013.1 a 2016.1 e 2013.2 a 2016.2), a partir da coleta de dados realizada em 2017 e primeiro quadrimestre de 2018. Foram realizadas entrevistas semiestruturadas com: estudante ingressante, estudante graduando, estudante evadido e estudante graduado. A seleção dos entrevistados foi feita de forma aleatória. As entrevistas foram transcritas e passaram por análise qualitativa de conteúdo descrito por Hoffman (2013). Foram encontradas as seguintes categorias: auxílio financeiro, trabalho versus estudo, conteúdo das disciplinas, sentimento de pertencimento, experiência docente, escolha do curso, evasão e desempenho do curso. O estudo realizou pesquisa qualitativa através de leitura de documentos institucionais, periódicos, artigos, dissertações, teses e livros. Constatou-se que a evasão e a permanência teriam como responsáveis as questões financeiras e deficiências na formação da escolarização básica.

Discovering $E_6$ SUSY models in gluino cascade decays at the LHC

description: We point out that the extra neutralinos and charginos generically appearing in a large class of $E_6$ inspired models lead to distinctive signatures from gluino cascade decays in comparison to those from the Minimal Supersymmetric Standard Model (MSSM). These signatures involve longer decay chains, more visible transverse energy, higher multiplicities of jets and leptons, and less missing transverse energy than in the MSSM. These features make the gluino harder to discover for certain types of conventional analyses, for example in the 6 jet channel we show that a 1 TeV MSSM gluino may resemble an 800 GeV $E_6$ gluino. However, the enriched lepton multiplicity provides enhanced 3- and 4-lepton signatures, which are much more suppressed in the case of the MSSM. As an example we analyse various scenarios in the E$_6$SSM, demonstrating the utility of a \texttt{CalcHEP} model that we have now made publicly available on HEPMDB (High Energy Physics Models DataBase). After extensive scans over the parameter space, we focus on representative benchmark points. We perform detailed Monte Carlo analyses, concentrating on the 3-lepton channel at the 7, 8, and 14 TeV Large Hadron Collider (LHC), and demonstrate that $E_6$ inspired models are clearly distinguishable from the MSSM in gluino cascade decays. We emphasise to the LHC experimental groups that the distinctive features present in gluino cascade decays, such as those discussed here, not only represents a unique footprint of a particular model but also may provide the key to an earlier discovery of supersymmetry.

description: Warm inflation has normalized two ideas in cosmology, that in the early universe the initial primordial density perturbations generally could be of classical rather than quantum origin and that during inflation, particle production from interactions amongst quantum field, and its backreaction effects, can occur concurrent with inflationary expansion. When we first introduced these ideas, both were met with resistance, but today they are widely accepted as possibilities with many models and applications based on them, which is an indication of the widespread influence of warm inflation. Open quantum field theory, which has been utilized in studies of warm inflation, is by now a relevant subject in cosmology, in part due to this early work. In this review I first discuss the basic warm inflation dynamics. I then outline how to compute warm inflation dynamics from first principles quantum field theory (QFT) and in particular how a dissipative term arises. Warm inflation models can have an inflaton mass bigger than the Hubble scale and the inflaton field excursion can remain sub-Planckian, thus overcoming the most prohibitive problems of inflation model building. I discuss the early period of my work in developing warm inflation that helped me arrive at these important features of its dynamics. Inflationary cosmology today is immersed in hypothetical models, which by now are acting as a diversion from reaching any endgame in this field. I discuss better ways to approach model selection and give necessary requirements for a well constrained and predictive inflation model. A few warm inflation models are pointed out that could be developed to this extent. I discuss how at this stage more progress would be made in this subject by taking a broader view on the possible early universe solutions that include not just inflation but the diverse range of options.

description: We calculate the upper bounds of the population of theoretically stable Centaur orbits between Uranus and Neptune. These small bodies are on low-eccentricity, low-inclination orbits in two specific bands of semi-major axis, centred at $\sim$24.6 au and $\sim$25.6 au. They exhibit unusually long Gyr-stable lifetimes in previously published numerical integrations, orders of magnitude longer than that of a typical Centaur. Despite the increased breadth and depth of recent solar system surveys, no such objects have been found. Using the Outer Solar System Origins Survey (OSSOS) survey simulator to calculate the detection efficiency for these objects in an ensemble of fully characterised surveys, we determine that a population of 72 stable Centaurs with absolute magnitude $H_{r}\leq10$ ($95\%$ confidence upper limit) could remain undetected. The upcoming Legacy Survey of Space and Time (LSST) will be able to detect this entire intrinsic population due to its complete coverage of the ecliptic plane. If detected, these objects will be interesting dynamically-accessible mission targets -- especially as comparison of the stable Centaur orbital phase space to the outcomes of several modern planetary migration simulations suggests that these objects could be close to primordial in nature.

description: Low-temperature variable-energy electron irradiation was used to induce non-magnetic disorder in a single crystal of hole-doped iron-based superconductor, Ba$_{1-x}$K$_x$Fe$_2$As$_2$, $x=$0.80. To avoid systematic errors, the beam energy was adjusted non-consequently for five values between 1.0 and 2.5 MeV, whence sample resistance was measured in-situ at 22 K. For all energies, the resistivity raises linearly with the irradiation fluence suggesting the creation of uncorrelated dilute point-like disorder (confirmed by simulations). The rate of the resistivity increase peaks at energies below 1.5 MeV. Comparison with calculated partial cross-sections points to the predominant creation of defects in the iron sublattice. Simultaneously, superconducting $T_c$, measured separately between the irradiation runs, is monotonically suppressed as expected since it depends on the total scattering rate, hence total cross-section, which is a monotonically increasing function of energy. Our work confirms experimentally an often-made assumption of the dominant role of the iron sub-lattice in iron-based superconductors.

description: In this work a novel radar simulation concept is introduced that allows to simulate realistic radar data for Range, Doppler, and for arbitrary antenna positions in an efficient way. Further, it makes it possible to automatically annotate the simulated radar signal by allowing to decompose it into different parts. This approach allows not only almost perfect annotations possible, but also allows the annotation of exotic effects, such as multi-path effects or to label signal parts originating from different parts of an object. This is possible by adapting the computation process of a Monte Carlo shooting and bouncing rays (SBR) simulator. By considering the hits of each simulated ray, various meta data can be stored such as hit position, mesh pointer, object IDs, and many more. This collected meta data can then be utilized to predict the change of path lengths introduced by object motion to obtain Doppler information or to apply specific ray filter rules in order obtain radar signals that only fulfil specific conditions, such as multiple bounces or containing specific object IDs. Using this approach, perfect and otherwise almost impossible annotations schemes can be realized.

In this thesis, I demonstrated, using complementary correlational and experimental approaches, that dark-eyed juncos (Junco hyemalis) increase the frequency of their songs in response to noise. Next, I broadcasted noise-altered and unaltered songs in noisy and quiet environments and re-recorded them along a 40-m transect, with microphones set up at 1, 5, 15, and 40 m. I measured song degradation along the transect and found that songs degraded predictably with increasing distance, but that recording environment (noisy or quiet), playback environment (noisy or quiet), and the interaction between the two had no effect on song degradation. This indicates that, although juncos increase the minimum frequency of their songs in response to noise, the shift does not, by itself, increase the transmission of the song through noise.

description: This paper presents an adaptive horizon multi-stage model-predictive control (MPC) algorithm. It establishes appropriate criteria for recursive feasibility and robust stability using the theory of input-to-state practical stability (ISpS). The proposed algorithm employs parametric nonlinear programming (NLP) sensitivity and terminal ingredients to determine the minimum stabilizing prediction horizon for all the scenarios considered in the subsequent iterations of the multi-stage MPC. This technique notably decreases the computational cost in nonlinear model-predictive control systems with uncertainty, as they involve solving large and complex optimization problems. The efficacy of the controller is illustrated using three numerical examples that illustrate a reduction in computational delay in multi-stage MPC.

description: Phase-field models are widely employed to simulate microstructure evolution during processes such as solidification or heat treatment. The resulting partial differential equations, often strongly coupled together, may be solved by a broad range of numerical methods, but this often results in a high computational cost, which calls for advanced numerical methods to accelerate their resolution. Here, we quantitatively test the efficiency and accuracy of semi-implicit Fourier spectral-based methods, implemented in Python programming language and parallelized on a graphics processing unit (GPU), for solving a phase-field model coupling Cahn-Hilliard and Allen-Cahn equations. We compare computational performance and accuracy with a standard explicit finite difference (FD) implementation with similar GPU parallelization on the same hardware. For a similar spatial discretization, the semi-implicit Fourier spectral (FS) solvers outperform the FD resolution as soon as the time step can be taken 5 to 6 times higher than afforded for the stability of the FD scheme. The accuracy of the FS methods also remains excellent even for coarse grids, while that of FD deteriorates significantly. Therefore, for an equivalent level of accuracy, semi-implicit FS methods severely outperform explicit FD, by up to 4 orders of magnitude, as they allow much coarser spatial and temporal discretization.

description: We study the classification of area-stationary and stable $C^2$ regular surfaces in the space of the rigid motions of the Minkowski plane E(1,1), equipped with its sub-Riemannian structure. We construct examples of area-stationary surfaces that are not foliated by sub-Riemannian geodesics. We also prove that there exist an infinite number of $C^2$ area-stationary surfaces with a singular curve. Finally we show the stability of $C^2$ area-stationary surfaces foliated by sub-Riemannian geodesics.

description: Although New Zealand provides an ideal site to explore offshore gas hydrate extraction as a potential future energy resource, its commercial viability can only be explored if production can proceed safely. Consequently, determining whether offshore gas hydrate extraction could generate geohazards, such as submarine landslides, is essential but rarely studied. This report characterises the geotechnical properties of typical sediment types retrieved from the HYDEE Programme (Gas Hydrates: Economic Opportunities and Environmental Implications) study area during the 2016 Sonne and 2017/18 International Ocean Discovery Program (IODP) expeditions. The sediments tested in this study are compared with previous geotechnical data from the area to provide representative geotechnical parameters to inform conceptual modelling and stability assessments.

description: The quantum-classical correspondence between local minima on the classical energy landscape and excited eigenstates in the energy spectrum is studied within the context of many-body quantum spin systems. In mean-field approximations of a quantum problem, one usually focuses on attaining the global minimum of the resulting energy function, while other minimum solutions are usually ignored. For frustrated systems, a strict distinction between global and local minimum is often not tenable since first-order type transitions can interchange the roles played by two different minima. This begs the question of whether there is any physical interpretation for the local minima encountered in mean-field approximations of quantum systems. We look at the problem from the perspective of quantum spin systems. Two models are studied, a frustrated model with quenched disorder, and a pure system without frustration. Accurate classical energies of the minima are compared with the full spectrum of energy levels, allowing us to search for signs of correspondence between them. It is found that the local minima can generally be interpreted as excited energy eigenstates. Instances of spurious minima are also reported.

description: A phase retrieval technique using a spatial light modulator (SLM) and a phase diffuser for a fast reconstruction of smooth wave fronts is demonstrated experimentally. Diffuse illumination of a smooth test object with the aid of a phase diffuser (maximum phase shift, Df = 0.85p) results in a significant diversity in the intensity measurements which, in turn, is beneficial for a non-stagnating iterative phase reconstruction. The use of the SLM enables accurate and fast speckle intensity recording and active correction of misalignments in the setup. The effectiveness of the technique is demonstrated in the optical testing of lenses.

description: Cell entry by coronaviruses involves two principal steps, receptor binding and membrane fusion; the latter requires activation by host proteases, particularly lysosomal proteases. Despite the importance of lysosomal proteases in both coronavirus entry and cell metabolism, the correlation between lysosomal proteases and cell tropism of coronaviruses has not been established. Here, we examined the roles of lysosomal proteases in activating coronavirus surface spike proteins for membrane fusion, using the spike proteins from severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV) as the model system. To this end, we controlled the contributions from receptor binding and other host proteases, thereby attributing coronavirus entry solely or mainly to the efficiency of lysosomal proteases in activating coronavirus spike-mediated membrane fusion. Our results showed that lysosomal proteases from bat cells support coronavirus spike-mediated pseudovirus entry and cell-cell fusion more effectively than their counterparts from human cells. Moreover, purified lysosomal extracts from bat cells cleave cell surface-expressed coronavirus spikes more efficiently than their counterparts from human cells. Overall, our study suggests that different lysosomal protease activities from different host species and tissue cells are an important determinant of the species and tissue tropism of coronaviruses.IMPORTANCE Coronaviruses are capable of colonizing new species, as evidenced by the recent emergence of SARS and MERS coronaviruses; they can also infect multiple tissues in the same species. Lysosomal proteases play critical roles in coronavirus entry by cleaving coronavirus surface spike proteins and activating the fusion of host and viral membranes; they also play critical roles in cell physiology by processing cellular products. How do different lysosomal protease activities from different cells impact coronavirus entry? Here, we controlled the contributions from known factors that function in coronavirus entry so that lysosomal protease activities became the only or the main determinant of coronavirus entry. Using pseudovirus entry, cell-cell fusion, and biochemical assays, we showed that lysosomal proteases from bat cells activate coronavirus spike-mediated membrane fusion more efficiently than their counterparts from human cells. Our study provides the first direct evidence supporting lysosomal proteases as a determinant of the species and tissue tropisms of coronaviruses.
