description: The late Early Cretaceous greenhouse climate has been studied intensively based on proxy data derived essentially from open marine archives. In contrast, information on continental climatic conditions and on the accompanying response of vegetation is relatively scarce, most notably owing to the stratigraphic uncertainties associated with many Lower Cretaceous terrestrial deposits. Here, we present a palynological record from Albian near-shore deposits of the Lusitanian Basin of W Portugal, which have been independently dated using Sr-isotope signals derived from low-Mg oyster shell calcite. 87Sr/86Sr values fluctuate between 0.707373 ± 0.00002 and 0.707456 ± 0.00003; absolute values and the overall stratigraphic trend match well with the global open marine seawater signature during Albian times. Based on the new Sr-isotope data, existing biostratigraphic assignments of the succession are corroborated and partly revised. Spore-pollen data provide information on the vegetation community structure and are flanked by sedimentological and clay mineralogical data used to infer the overall climatic conditions prevailing on the adjacent continent. Variations in the distribution of climate-sensitive pollen and spores indicate distinct changes in moisture availability across the studied succession with a pronounced increase in hygrophilous spores in late Early Albian times. Comparison with time-equivalent palynofloras from the Algarve Basin of southern Portugal shows pronounced differences in the xerophyte/hygrophyte ratio, interpreted to reflect the effect of a broad arid climate belt covering southern and southeastern Iberia during Early Albian times. © 2012 Cambridge University Press.

description: Effective search for graph automorphisms allows identifying symmetries in many discrete structures, ranging from chemical molecules to microprocessor circuits. Using this type of structure can enhance visualization as well as speed up computational optimization and verification. Competitive algorithms for the graph automorphism problem are based on efficient partition refinement augmented with group-theoretic pruning techniques. In this paper, we improve prior algorithms for the graph automorphism problem by introducing simultaneous refinement of multiple partitions, which enables the anticipation of future conflicts in search and leads to significant pruning, reducing overall runtimes. Empirically, we observe an exponential speedup for the family of Miyazaki graphs, which have been shown to impede leading graph-automorphism algorithms.

description: A comprehensive process model is proposed to simulate the steam gasification of biomass in a bubbling fluidized bed reactor using the Aspen Plus simulator. The reactor models are implemented using external FORTRAN codes for hydrodynamic and reaction kinetic calculations. Governing hydrodynamic equations and kinetic reaction rates for char gasification and water-gas shift reactions are obtained from experimental investigations and the literature. Experimental results at different operating conditions from steam gasification of torrefied biomass in a pilot-scale gasifier are used to validate the process model. Gasification temperature and steam-to-biomass ratio promote hydrogen production and improve process efficiencies. The steam-to-biomass ratio is directly proportional to an increase in the content of hydrogen and carbon monoxide, while gas yield and carbon conversion efficiency enhance significantly with increasing temperature. The model predictions are in good agreement with experimental data. The mean error of CO₂ shows the highest value of 0.329 for the steam-to-biomass ratio and the lowest deviation is at 0.033 of carbon conversion efficiency, respectively. The validated model is capable of simulating biomass gasification under various operating conditions.

description: Studies dealing with the response of the continental biosphere to the environmental perturbations associated with Cretaceous oceanic anoxic events (OAEs) are comparatively rare. Here, a quantitative spore-pollen record combined with clay mineral data is presented, which covers the entire early Aptian OAE 1a interval (Forcall Formation, Maestrat basin, east Spain). The well-expressed OAE 1a carbon-isotope anomaly is paralleled by changes in the clay mineral assemblage and by a stepwise decline in the normalized frequency of Classopollis pollen (produced by xerophytic Cheirolepidiaceae) with lowest contents occurring during the positive δ13C shift. In contrast, Araucariacites and Inaperturopollenites pollen show a pronounced increase in relative abundance from low background values to become a significant component of the palynological assemblage during the Classopollis minimum. The observed changes in clay minerals and pollen distribution patterns are interpreted to reflect a major change in the composition of the hinterland vegetation of the Maestrat Basin, most probably due to short-lived but pronounced climatic cooling and changes in humidity. Temperature anomalies driven by organic carbon burial and associated CO2 decline have been postulated for all major Mesozoic OAEs. The palynomorph record from the Iberian Maestrat basins indicates that the climax of this cooling episode was significantly delayed in comparison to the end of organic carbon-rich deposition in the world oceans.

Migration, Translingualism, Translation

description: When literary translation is involved, sociological approaches tend to devalue the aesthetic form of translated texts while framing them as social and political documents. Van Dyck analyzes literary representations of migration, one of the most pressing developments of our time, demonstrating how migrants engage in innovation linguistic practices and considering how a translator might render those practices. Two contemporary Greek novels -- one about Greeks in the United States, the other about Greek Alabanians in Greece -- create translingual spaces that are themselves translational as migrants use hybrid creoles that blend languages through transliteration and homophony, challenging the hegemony of standard dialects as well as monolingualism. Van Dyck questions existing English translations of these macaronic texts because they assume essentialist concepts of equivalence that dehistoricize the source texts. She instead proposes experimental translations that acknowledge their relative autonomy by introducing translingual patterning that is analogous but never identical to the migrants' linguistic innovations.

description: Morro Bay, California is a biotically-diverse region with a rich cultural history. In the archaeological community, there is an ongoing debate over the probable cause for an occupational hiatus in the region during the Middle Period (2600-1000 BP). This case study addresses this disparity and presents the results of a single component, deeply buried, Middle Period archaeological site. This thesis highlights how landform age, landscape evolution, and geoarchaeological methodology can affect the probability of identifying deeply buried archaeological sites. Interdisciplinary data (e.g., seismology, geology, geography, paleoseismology) have proven useful in making a significant contribution in the understanding of a previously unknown period of occupation in Morro Bay.

description: Symmetries of combinatorial objects are known to complicate search algorithms, but such obstacles can often be removed by detecting symmetries early and discarding symmetric subproblems. Canonical labeling of combinatorial objects facilitates easy equivalence checking through quick matching. All existing canonical labeling software also finds symmetries, but the fastest symmetry-finding software does not perform canonical labeling. In this work, we contrast the two problems and dissect typical algorithms to identify their similarities and differences. We then develop a novel approach to canonical labeling where symmetries are found first and then used to speed up the canonical labeling algorithms. Empirical results show that this approach outperforms state-of-the-art canonical labelers.

description: Zinc stannate (Zn 2SnO 4) nanoparticles with an average size of about 26 nm are synthesized via single-step mechanochemical processing of binary oxide precursors (ZnO and SnO 2) at ambient temperature, without the need for the subsequent calcination, thus making the synthesis route very simple and cost-effective. The mechanically induced phase evolution of the 2ZnO + SnO 2 mixture is followed by XRD and by a variety of spectroscopic techniques including 119Sn MAS NMR, Raman spectroscopy, 119Sn Mössbauer spectroscopy, and XPS. High-resolution TEM studies reveal a non-uniform structure of mechanosynthesized Zn 2SnO 4 nanoparticles consisting of a crystalline core surrounded by a structurally disordered surface shell. Due to the ability of the applied solid-state spectroscopies to probe the local environment of Sn cations, valuable complementary insight into the nature of the local structural disorder of mechanosynthesized Zn 2SnO 4 is obtained. The findings hint at a highly nonequilibrium state of the as-prepared stannate characterized by its partly inverse spinel structure and the presence of deformed polyhedra in the surface shell of nanoparticles. © 2012 The Royal Society of Chemistry.
Usable Machine Learning for Remote Sensing Data

Subjects: subject: Artificial intelligence

description: The desired output for most real-world tasks using machine learning (ML) and remote sensing data is a set of dense predictions that form a predicted map for a geographic region. However, most prior work involving ML and remote sensing follows the traditional practice of reporting metrics on a set of independent, geographically-sparse samples and does not perform dense predictions. To reduce the labor of producing dense prediction maps, we present OpenMapFlow— an open-source python library for rapid map creation with ML and remote sensing data. OpenMapFlow provides 1) a data processing pipeline for users to create labeled datasets for any region, 2) code to train state-of-the-art deep learning models on custom or existing datasets, and 3) a cloud-based architecture to deploy models for efficient map prediction. We demonstrate the benefits of OpenMapFlow through experiments on three binary classification tasks: cropland, crop type (maize), and building mapping. We show that OpenMapFlow drastically reduces the time required for dense prediction compared to traditional workflows. To more broadly understand method adoption we present ML for Remote Sensing Usability Cards to assess usability for machine learning with remote sensing data and use this framework to conduct a case study of a workflow developed with OpenMapFlow. We hope this library will stimulate novel research in areas such as domain shift, unsupervised learning, and societally-relevant applications and along with the usability framework lessen the barrier to adopting research methods for real-world tasks.

description: Titanium–tantalum based alloys can demonstrate a martensitic transformation well above 100 °C, which makes them attractive for shape memory applications at elevated temperatures. In addition, they provide for good workability and contain only reasonably priced constituents. The current study presents results from functional fatigue experiments on a binary Ti–25Ta high-temperature shape memory alloy. This material shows a martensitic transformation at about 350 °C along with a transformation strain of 2 pct at a bias stress of 100 MPa. The success of most of the envisaged applications will, however, hinge on the microstructural stability under thermomechanical loading. Thus, light and electron optical microscopy as well X-ray diffraction were used to uncover the mechanisms that dominate functional degradation in different temperature regimes. It is demonstrated the maximum test temperature is the key parameter that governs functional degradation in the thermomechanical fatigue tests. Specifically, ω-phase formation and local decomposition in Ti-rich and Ta-rich areas dominate when T max does not exceed ≈430 °C. As T max is increased, the detrimental phases start to dissolve and functional fatigue can be suppressed. However, when T max reaches ≈620 °C, structural fatigue sets in, and fatigue life is again deteriorated by oxygen-induced crack formation. Copyright © Materials Research Society 2017

description: Random walks in random scenery are processes defined by $$Z_n:=\sum_{k=1}^nω_{S_k}$$ where $S:=(S_k,k\ge 0)$ is a random walk evolving in $\mathbb{Z}^d$ and $ω:=(ω_x, x\in{\mathbb Z}^d)$ is a sequence of i.i.d. real random variables. Under suitable assumptions on the random walk $S$ and the random scenery $ω$, almost surely with respect to $ω$, the correctly renormalized sequence $(Z_n)_{n\geq 1}$ is proved to converge in distribution to a centered Gaussian law with explicit variance.

Effects of Kerr Strong Gravity on Quasar X-ray Microlensing

description: Recent quasar microlensing observations have constrained the sizes of X-ray emission regions to be within about 10 gravitational radii of the central supermassive black hole. Therefore, the X-ray emission from lensed quasars is first strongly lensed by the black hole before it is lensed by the foreground galaxy and star fields. We present a scheme that combines the initial strong lensing of a Kerr black hole with standard linearized microlensing by intervening stars. We find that X-ray microlensed light curves incorporating Kerr strong gravity can differ significantly from standard curves. The amplitude of the fluctuations in the light curves can increase or decrease by ~0.65-0.75 mag by including Kerr strong gravity. Larger inclination angles give larger amplitude fluctuations in the microlensing light curves. Consequently, current X-ray microlensing observations might have under or overestimated the sizes of the X-ray emission regions. We estimate this bias using a simple metric based on the amplitude of magnitude fluctuations. The half light radius of the X-ray emission region can be underestimated up to ~50% or overestimated up to ~20%. Underestimates are found in most situations we have investigated. The only exception is for a disk with large spin, radially flat emission profile, and observed nearly face on, where an overestimate is found. Thus, more accurate microlensing size constraints should be obtainable by including Kerr lensing. The caustic crossing time can differ by months after including Kerr strong gravity. A simultaneous monitoring of gravitational lensed quasars in both X-ray and optical bands with densely sampled X-ray light curves might reveal this feature. We conclude that it should be possible to constrain important parameters such as inclination angles and black hole spins from combined Kerr and microlensing effects.

On the role of the Barbero-Immirzi parameter in discrete quantum gravity

description: The 1-parameter family of transformations identified by Barbero and Immirzi plays a significant role in non-perturbative approaches to quantum gravity, among them Loop Quantum Gravity and Spin Foams. It facilitates the loop quantization programme and subsequently the Barbero-Immirzi parameter (gamma) arises in both the spectra of geometrical operators and in the dynamics provided by Spin Foams. However, the debate continues as to whether quantum physics should be Barbero-Immirzi parameter dependent. Starting from a discrete SO(4)-BF theory phase space, we find two possible reductions with respect to a discrete form of the simplicity constraints. The first reduces to a phase space with gamma-dependent symplectic structure and more generally in agreement with the phase space underlying Loop Quantum Gravity restricted to a single graph - a.k.a. Twisted Geometries. The second, fuller reduction leads to a gamma-independent symplectic structure on the phase space of piecewise-flat-linear geometries - a.k.a. Regge geometries. Thus, the gamma-dependence of physical predictions is related to the choice of phase space underlying the quantization.

description: Disordered eating in college student populations is highly prevalent. Even so, eating disorder research has largely centered on risk and protective factors relevant to White women, while neglecting to focus on the experiences of people with marginalized identities. The current cross-sectional study a) assessed the relation between evaluative concerns and strivings subscales of perfectionism on disordered eating symptoms in Latinx college women, and b) determined if a high sense of ethnic identity may moderate this relation such that as ethnic identity increases, the effects of perfectionism on disordered eating symptoms decreases. Latinx women from a Mid-Atlantic university (n = 113) completed self-report questionnaires of perfectionism, ethnic identity, and disordered eating. Results revealed that evaluative concerns was a positive predictor of dietary restraint, shape and weight over-evaluation, and body dissatisfaction. Moderation results were non-significant.
Damage Spreading in a Driven Lattice Gas Model

description: We studied damage spreading in a Driven Lattice Gas (DLG) model as a function of the temperature $T$, the magnitude of the external driving field $E$, and the lattice size. The DLG model undergoes an order-disorder second-order phase transition at the critical temperature $T_c(E)$, such that the ordered phase is characterized by high-density strips running along the direction of the applied field; while in the disordered phase one has a lattice-gas-like behaviour. It is found that the damage always spreads for all the investigated temperatures and reaches a saturation value $D_{sat}$ that depends only on $T$. $D_{sat}$ increases for $TT_c(E=\infty)$ and is free of finite-size effects. This behaviour can be explained as due to the existence of interfaces between the high-density strips and the lattice-gas-like phase whose roughness depends on $T$. Also, we investigated damage spreading for a range of finite fields as a function of $T$, finding a behaviour similar to that of the case with $E=\infty$.

description: Der vorliegende Beitrag fasst Inklusion unter Bezugnahme auf Oevermanns (1996) „Skizze einer revidierten Theorie professionalisierten Handelns“ als Auftrag zur Professionalisierung entlang der therapeutischen Dimension in der Beziehung von Lehrpersonen und Schüler*innen. Dieser trifft in der beruflichen Bildung auf ein spezifisches Spannungsfeld, insofern unter dem Primat der Beruflichkeit eine starke Fokussierung auf ‚Wissen und Können‘ prozessiert wird. Vor diesem Hintergrund wird exemplarisch die Ausgestaltung der pädagogischen Praxis anhand von im BMBF-geförderten Forschungsprojekt StiEL entstandenen Datenmaterial mittels der Dokumentarischen Methode der Textinterpretation analysiert. Ziel ist es, die Orientierungen von Lehrpersonen hinsichtlich pädagogischer Fachlichkeit aus deren handlungsleitenden Wissensbeständen heraus zu rekonstruieren, um die Bedingungen für die Aufnahme des Inklusionsanspruchs in den eigenen Unterricht sowie implizite, durch den Anspruch ‚Inklusion‘ hervorgerufene Ambivalenzen des pädagogisch-professionellen Handelns sichtbar zu machen. Abschließend werden Ansatzpunkte für Fort- und Weiterbildungen abgeleitet. Abstract With reference to Oevermann (1996), the article interprets inclusion as need for professionalisation along the therapeutical dimension in the relationship between teachers and students. In the field of vocational education, there emerges a specific tension as a strong focus on ‚knowledge and skills‘ is processed. By using the documentary method of text interpretation this article analyses the pedagogical practice on the data basis from the research project StiEL (founded by the German Federal Ministry of Education and Research). The aim is to reconstruct orientations on pedagogical professionalism in teachers‘ practical knowledge. Hereby, it endeavours to show the conditions for inclusion within teachers‘ tuition as well as implicit ambivalences in their professional pedagogical action caused by implementing inclusion. Finally, implications for teacher training are derived.

description: Global reggaetón superstar Bad Bunny has performed in traditionally “female” clothes, worn nail polish, and kissed men on the international stage, but has never named his identity explicitly. Many have taken to the internet to call him, among many other celebrities a “queer baiter .” With US representational politics and queer people in the spotlight – this thesis wonders how homonormativity and neo-imperial respectability politics fueled these queer-baiting discourses. This thesis aims to tackle the contemporary debates surrounding racialized minoritarian subjects in reggaetón who are constantly caught in discourses of “too queer” or “not queer enough.” These queers frequently under colonial or neo-imperial rule, negotiate the boundaries of American homonormativity and obsession with “outness.” This thesis takes up the idea of “queerbaiting” and questions, “what happens when people outside the homo-“norms” perform their queerness in a way that is not necessarily legible to other global queers?” Utilizing methods from performance, queer, and Latine and Caribbean studies, I argue that we need new understandings of what it means to be queer. Using case studies from the reggaetón genre of Puerto Rico and the Dominican Republic, I argue that performances by Bad Bunny, Tokischa, and Ivy Queen negotiate, performances of queerness that exceed those of US imperial homonormativity. Intervention statement: this redefines how we come to understand our own queerness and futures and how we understand the most popular global music genre.

description: Quantum entanglement of two photons created by spontaneous parametric downconversion (SPDC) can be used to probe quantum optical phenomena during a single cycle of light. Harris [Phys. Rev. Lett. 98, 063602 (2007)] suggested using ultrabroad parametric fluorescence generated from a quasi-phase-matched (QPM) device whose poling period is chirped. In the Harris\' s original proposal, it is assumed that the photons are collinearly generated and then spatially separated by frequency filtering. Here, we alternatively propose using noncollinearly generated SPDC. In our numerical calculation, to achieve 1.2 cycle temporal correlation for a 532 nm pump laser, only 10% -chirped device is sufficient when noncollinear condition is applied, while a largely chirped (50%) device is required in collinear condition. We also experimentally demonstrate an octave-spanning (790-1610 nm) noncollinear parametric fluorescence from a 10% chirped MgSLT crystal using both a superconducting nanowire single-photon detector and photomultiplier tube as photon detectors. The observed SPDC bandwidth is 194 THz, which is the largest width achieved to date for a chirped QPM device. From this experimental result, our numerical analysis predicts that the bi-photon can be compressed to 1.2 cycles with appropriate phase compensation.

description: We introduce the notion of Kravchuk derivations of the polynomial algebra. We prove that any element of the kernel of the derivation gives a polynomial identity satisfied by the Kravchuk polynomials. Also, we prove that any kernel element of the basic Weitzenbök derivations yields a polynomial identity satisfied by the Kravchuk polynomials. We describe the corresponding intertwining maps.

An extended representation of three spin component Bose Einstein Condensate solitons

description: We consider a three spin component Bose Einstein Condensate as described by as many coupled nonlinear Schroedinger equations. For a very special ratio of the coupling constants, exact N soliton solutions to this set of equations are known. Here we find a simple representation including the N = 1 solution based on the symmetry of the equations. This symmetry is described by a linear operator, the nonlinearity of NLS notwithstanding. Our useful representation opens the door to the nonintegrable case of general coupling constants. A new class of solutions is found.

description: Parametric amplification of vacuum fluctuations is crucial in modern quantum optics, enabling the creation of squeezing and entanglement. We demonstrate the parametric amplification of vacuum fluctuations for matter waves using a spinor F = 2(87) Rb condensate. Interatomic interactions lead to correlated pair creation in the m(F) = +/- 1 states from an initial m(F) = 0 condensate, which acts as a vacuum for m(F) not equal 0. Although this pair creation from a pure mF 0 condensate is ideally triggered by vacuum fluctuations, unavoidable spurious initial m(F) = +/- 1 atoms induce a classical seed which may become the dominant triggering mechanism. We show that pair creation is insensitive to a classical seed for sufficiently large magnetic fields, demonstrating the dominant role of vacuum fluctuations. The presented system thus provides a direct path towards the generation of nonclassical states of matter.

description: In diesem Beitrag wird der Prototyp eines aktiven Scheinwerfers vorgestellt, der durch den Einsatz eines Mikrospiegelarrays (DMD) hochaufgelöste Lichtverteilungen generieren kann. Mit der eingesetzten verzeichnenden Projektionsoptik wird das Aspektverhältnis entsprechen-de einer KFZ-Lichtverteilung aufgeweitet und ein mittiger Hotspot mit hoher Beleuchtungs-stärke erzeugt. Dadurch kann der Nutzungsgrad der Mikrospiegel und damit der Systemwir-kungsgrad im Vergleich zu bisherigen Prototypen deutlich gesteigert werden, was anhand einer typischen Fernlichtverteilung gezeigt wird. Basierend auf der optischen Simulation wer-den die Vor- und Nachteile der verzeichnenden Optik diskutiert und abschließend Ergebnisse der photometrischen Vermessung des Prototyps vorgestellt.
description: In this paper we present the prototype of an active headlamp that can generate high-resolution light distributions by using a micromirror array (DMD). A distortive projection optics is used to widen the aspect ratio according to a headlamp light distribution and to generate a central hotspot with high illuminance. As a result, the degree of utilization of the micromirror and thus the system efficiency compared to previous prototypes can be significantly in-creased, as shown by a typical high beam distribution. Based on the optical simulation, the advantages and disadvantages of the distortive optics are discussed and finally results of the photometric measurement of the prototype are presented.

description: The COVID-19 pandemic caused tremendous supply bottlenecks of single-use filtering facepiece respirators (FFRs) leading to a growing need for a potential reuse. This study assesses the impact of multiple mild-steam decontaminations with 121 °C/2000 mbar/20 min on the protection performance of disposable FFRs. It focuses on FFRs of type KN95 that is recently dominating the markets, but its decontamination is not covered in the literature. It was found that up to ten cycles, only minor degradation in the filter efficiency, breathing resistance and none in the material structure is apparent, suggesting a potential for multiple decontamination cycles at almost unchanged protective properties of KN95 FFRs.
