description: We show that for sufficiently large $n$, every 3-uniform hypergraph on $n$ vertices with minimum vertex degree at least $\binom{n-1}2 - \binom{\lfloor\frac34 n\rfloor}2 + c$, where $c=2$ if $n\in 4\mathbb{N}$ and $c=1$ if $n\in 2\mathbb{N}\setminus 4\mathbb{N}$, contains a loose Hamilton cycle. This degree condition is best possible and improves on the work of Buß, Hàn and Schacht who proved the corresponding asymptotical result.

description: Nonsymmetric Koornwinder polynomials are multivariable extensions of nonsymmetric Askey-Wilson polynomials. They naturally arise in the representation theory of (double) affine Hecke algebras. In this paper we discuss how nonsymmetric Koornwinder polynomials naturally arise in the theory of the Heisenberg XXZ spin-$\frac{1}{2}$ chain with general reflecting boundary conditions. A central role in this story is played by an explicit two-parameter family of spin representations of the two-boundary Temperley-Lieb algebra. These spin representations have three different appearances. Their original definition relates them directly to the XXZ spin chain, in the form of matchmaker representations they relate to Temperley-Lieb loop models in statistical physics, while their realization as principal series representations leads to the link with nonsymmetric Koornwinder polynomials. The nonsymmetric difference Cherednik-Matsuo correspondence allows to construct for special parameter values Laurent-polynomial solutions of the associated reflection quantum KZ equations in terms of nonsymmetric Koornwinder polynomials. We discuss these aspects in detail by revisiting and extending work of De Gier, Kasatani, Nichols, Cherednik, the first author and many others.

description: This article studies the relationship between tropical Severi varieties and secondary fans. In the case when tropical Severi varieties are hypersurfaces this relationship is very well known; specifically, in this case, a tropical Severi variety of codimension 1 is a subfan of the corresponding secondary fan. It was expected for some time that this continues to hold more generally, but Katz found a counterexample in codimension 2, showing that this relationship is more subtle. The two main results in this paper are as follows. The first theorem finds a simple condition under which a tropical Severi variety cannot be a subfan of the corresponding secondary fan. The second theorem provides a partial converse, namely, we find conditions under which a cone of the secondary fan is fully contained in the tropical Severi variety. As a first application of these results, we also find a combinatorial formula for the tropical intersection multiplicities for secondary fans.

description: Dans une perspective de démocratisation des savoirs, l’école inclusive suppose la prise en compte des besoins des élèves en situation de handicap dans tous les temps d’enseignement et notamment dans ceux d’évaluation. Lorsque l’élève n’est pas en mesure d’investir le processus d’apprentissage et d’accéder à certains savoirs, l’enseignant·e doit adapter ses modalités d’évaluation. De ce point de vue, l’évaluation formative, qui nécessite des interactions avec l’élève, peut devenir problématique si de l’incompréhension s’immisce dans les échanges, et si les attendus de l’enseignant·e ne sont pas explicites pour celle ou celui qui apprend. Comment donner du pouvoir d’agir à l’élève en situation de handicap par des feedbacks adaptés dans environnement capacitant afin qu’elle·il entre dans les apprentissages ? Nous étudions ici le cas d’un enseignant d’arts plastiques qui suit une formation pour scolariser les élèves en situation de handicap. À travers l’observation sur une année de ses pratiques d’évaluation en classe auprès de deux élèves en situation de handicap, nous chercherons à comprendre : 1- Comment il adapte ses interactions et l’environnement d’apprentissage lors de phases d’évaluation formative afin de permettre une démocratisation des savoirs ; 2- Comment, ce faisant, il leur redonne une forme de pouvoir d’agir dans leur scolarité. Les résultats nous permettent d’observer une transformation des pratiques de l’enseignant, liée à une meilleure connaissance des processus cognitifs de l’élève et des contenus de la formation. De leur côté, les élèves en situation de handicap qui étaient au départ des apprenants passifs deviennent acteurs de leurs apprentissages chacun à leur façon.

description: While the subject of racism is currently drawing social attention increasingly, the presence of racist structures and stereotypes in the most diverse areas of contemporary German society is being proven and exposed. Against this background, the research shed light on the importance of German-language children’s literature for the internalisation of racist thought patterns. Based on close reading of selected contemporary children’s books, the re_production and communication of various manifestations of racism are analysed. From an intersectional perspective, standards of anti-discrimination in the literary world are recommended to promote more diversity in children’s literature and anti-racist thinking.

description: The Event Horizon Telescope (EHT) has produced images of two supermassive black holes, Messier~87* (M 87*) and Sagittarius~A* (Sgr A*). The EHT collaboration used these images to indirectly constrain black hole parameters by calibrating measurements of the sky-plane emission morphology to images of general relativistic magnetohydrodynamic (GRMHD) simulations. Here, we develop a model for directly constraining the black hole mass, spin, and inclination through signatures of lensing, redshift, and frame dragging, while simultaneously marginalizing over the unknown accretion and emission properties. By assuming optically thin, axisymmetric, equatorial emission near the black hole, our model gains orders of magnitude in speed over similar approaches that require radiative transfer. Using 2017 EHT M 87* baseline coverage, we use fits of the model to itself to show that the data are insufficient to demonstrate existence of the photon ring. We then survey time-averaged GRMHD simulations fitting EHT-like data, and find that our model is best-suited to fitting magnetically arrested disks, which are the favored class of simulations for both M 87* and Sgr A*. For these simulations, the best-fit model parameters are within ${\sim}10\%$ of the true mass and within ${\sim}10^\circ$ for inclination. With 2017 EHT coverage and 1\% fractional uncertainty on amplitudes, spin is unconstrained. Accurate inference of spin axis position angle depends strongly on spin and electron temperature. Our results show the promise of directly constraining black hole spacetimes with interferometric data, but they also show that nearly identical images permit large differences in black hole properties, highlighting degeneracies between the plasma properties, spacetime, and most crucially, the unknown emission geometry when studying lensed accretion flow images at a single frequency.

description: We present 230 GHz continuum polarization observations with the Atacama Large Milimeter/Submillimeter Array (ALMA) at a resolution of 0$\farcs1$ ($\sim 540$~au) in the high-mass star-forming regions W51 e2 and e8. These observations resolve a network of core-connecting dust lanes, marking a departure from earlier coarser more spherical continuum structures. At the same time, the cores do not appear to fragment further. Polarized dust emission is clearly detected. The inferred magnetic field orientations are prevailingly parallel to dust lanes. This key structural feature is analyzed together with the local gravitational vector field. The direction of local gravity is found to typically align with dust lanes. With these findings we derive a stability criterion that defines a maximum magnetic field strength that can be overcome by an observed magnetic field-gravity configuration. Equivalently, this defines a minimum field strength that can stabilize dust lanes against a radial collapse. We find that the detected dust lanes in W51 e2 and e8 are stable, hence possibly making them a fundamental component in the accretion onto central sources, providing support for massive star formation models without the need of large accretion disks. When comparing to coarser resolutions, covering the scales of envelope, global, and local collapse, we find recurring similarities in the magnetic field structures and their corresponding gravitational vector fields. These self-similar structures point at a multi-scale collapse-within-collapse scenario until finally the scale of core-accreting dust lanes is reached where gravity is entraining the magnetic field and aligning it with the dust lanes.

description: The tensor-based theory of multidimensional x-space MPI provides useful insight into MPI image reconstruction. Using this theory, it was shown that x-space MPI images with isotropic resolution can be achieved by scanning in two orthogonal directions separately and combining the resulting images. In this work, we propose an x-space image reconstruction that resolves the multidimensional image tensor, allowing us to reconstruct the isotropic MPI image for the Lissajous trajectory. The proposed method takes advantage of the self-crossing property of the Lissajous trajectory.

description: Choice navigation, solution space development and robust process design are the three mass customization key competences. The first and second are often mapped into product configuration or design automation systems and aim at specifying or co-designing a suitable product variant. Robust process design targets at managing a well-known but flexible supply network. As part of this, the portfolio of capabilities describes limitations to the solution space and is a valuable source of knowledge containing general design guidelines and specific manufacturing restrictions, like NC travelling distances, as well as availabilities of whole production processes. This article contributes a modeling approach that bridges solutions space development and modeling the portfolio of capabilities. Therefore, a knowledge-based engineering system is extended by a capability model of according production machines that allows to automatically check new product variants against the portfolio of capabilities and to estimate setup efforts and expenses of process changes.

description: Raman spectroscopy is a well established tool for the analysis of vibration spectra, which then allow for the determination of individual substances in a chemical sample, or for their phase transitions. In the time-resolved-Raman-sprectroscopy the vibration spectra of a chemical sample are recorded sequentially over a time interval, such that conclusions for intermediate products (transients) can be drawn within a chemical process. The observed data-matrix M from a Raman spectroscopy can be regarded as a matrix product of two unknown matrices W and H, where the first is representing the contribution of the spectra and the latter represents the chemical spectra. One approach for obtaining W and H is the non-negative matrix factorization. We propose a novel approach, which does not need the commonly used separability assumption. The performance of this approach is shown on a real world chemical example.

description: The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) is a large-volume spectroscopic survey without pre-selection of sources, searching ~ 540 deg^2 for Lyman-alpha emitting galaxies (LAEs) at 1.9 < z < 3.5. Taking advantage of such a wide-volume survey, we perform a pilot study using early HETDEX data to search for lensed Lyman-alpha emitters. After performing a proof-of-concept using a previously known lensed LAE covered by HETDEX, we perform a search for previously unknown lensed LAEs in the HETDEX spectroscopic sample. We present a catalog of 26 potential LAEs lensed by foreground, red, non-star-forming galaxies at z ~ 0.4 - 0.7. We estimate the magnification for each candidate system, finding 12 candidates to be within the strong lensing regime (magnification $μ$ > 2). Follow-up observations of these potential lensed LAEs have the potential to confirm their lensed nature and explore these distant galaxies in more detail.

Polar Dust Emission in Quasar IR SEDs and Its Correlation with Narrow Line Regions

description: Polar dust has been found to play an important role in the mid-infrared emission of nearby Seyfert nuclei. If and how often polar dust exists among the quasar population is unknown due to the lack of spatially-resolved observations. In this Letter, we report correlations between the prominence of AGN forbidden line emission (commonly associated with the narrow line region) and the dust mid-IR energy output among the archetypal Palomar-Green quasar sample and other bright type-1 AGNs drawn from the SDSS, Spitzer and WISE archives. The AGN mid-IR color differences traced by WISE W2 ($\sim4.6 μm$)$-$W3 ($\sim12 μm$) and W2 ($\sim4.6 μm$)$-$W4 ($\sim22 μm$), and near-IR to mid-IR SEDs constrained with 2MASS, WISE and Spitzer data have clear trends with the relative strength of the forbidden line regions traced by the optical \OIII and mid-IR \OIV emission lines. These observations indicate that, where the lines are strong, a large fraction of the AGN emission at $λ\gtrsim5 μ$m comes from dust in the forbidden line regions. We find that the widely quoted universal AGN template is a result of averaging quasar SEDs with different levels of polar dust emission above the torus output and that the typical intrinsic IR SED of compact torus dust emission alone falls with increasing wavelength past 5 $μ$m (in $νF_ν$). In addition, the association of polar dust with the forbidden lines suggests an alternative to the receding torus hypothesis for the decrease in infrared output with increasing AGN luminosity.

description: When children learn to read, their neural system undergoes major changes to become responsive to print. There seem to be nuanced interindividual differences in the neurostructural anatomy of regions that later become integral parts of the reading network. These differences might affect literacy acquisition and, in some cases, might result in developmental disorders like dyslexia. Consequently, the main objective of this longitudinal study was to investigate those interindividual differences in gray matter morphology that might facilitate or hamper future reading acquisition. We used a machine learning approach to examine to what extent gray matter macrostructural features and cognitive-linguistic skills measured before formal literacy teaching could predict literacy 2 years later. Forty-two native German-speaking children underwent T1-weighted magnetic resonance imaging and psychometric testing at the end of kindergarten. They were tested again 2 years later to assess their literacy skills. A leave-one-out cross-validated machine-learning regression approach was applied to identify the best predictors of future literacy based on cognitive-linguistic preliterate behavioral skills and cortical measures in a priori selected areas of the future reading network. With surprisingly high accuracy, future literacy was predicted, predominantly based on gray matter volume in the left occipito-temporal cortex and local gyrification in the left insular, inferior frontal, and supramarginal gyri. Furthermore, phonological awareness significantly predicted future literacy. In sum, the results indicate that the brain morphology of the large-scale reading network at a preliterate age can predict how well children learn to read.

description: Complex interactive test items are becoming more widely used in assessments. Being computer-administered, assessments using interactive items allow logging time-stamped action sequences. These sequences pose a rich source of information that may facilitate investigating how examinees approach an item and arrive at their given response. There is a rich body of research leveraging action sequence data for investigating examinees’ behavior. However, the associated timing data have been considered mainly on the item-level, if at all. Considering timing data on the action-level in addition to action sequences, however, has vast potential to support a more fine-grained assessment of examinees’ behavior. We provide an approach that jointly considers action sequences and action-level times for identifying common response processes. In doing so, we integrate tools from clickstream analyses and graph-modeled data clustering with psychometrics. In our approach, we (a) provide similarity measures that are based on both actions and the associated action-level timing data and (b) subsequently employ cluster edge deletion for identifying homogeneous, interpretable, well-separated groups of action patterns, each describing a common response process. Guidelines on how to apply the approach are provided. The approach and its utility are illustrated on a complex problem-solving item from PIAAC 2012.

description: Introduction: Prolonged grief disorder (PGD) has been included as a new diagnosis in the ICD-11 and is set to be included in the DSM-5-TR. To better identify vulnerable individuals, different factors associated with PGD have to be taken into account, but results regarding these factors remain equivocal. Moreover, few studies on PGD are available from Arabic-speaking populations and from different countries dealing with conflicts and wars. The objective was thus to examine PGD prevalence and associated characteristics in these populations. Materials and methods: A total of N = 1,051 bereaved participants from Arabic-speaking populations completed the PG-13 as part of a screening procedure for an online mental health intervention. Multiple linear regression was conducted to examine associated factors for PGD symptom severity, and multiple logistic regression was applied to investigate associated factors for PGD according to PG-13 diagnostic criteria. Results: Of the participants, 18.8% (n = 198) met the PGD diagnostic criteria, at an average of about 6 years post-loss. The multiple linear regression yielded eight associated factors for PGD symptom severity (age, gender, number of losses, number of traumatic event types, relationship with the deceased, age at loss, impairment during first year post-loss, perceived social support), which explained 40.2% of the variance [F(17, N=1,033) = 40.82, p < 0.001, R2 = 0.402]. The multiple logistic regression yielded five significant associations with PGD (gender, relationship with the deceased, number of lost persons, impairment during first year post-loss, perceived social support), which explained 33.0% (Nagelkerke R2) of the variance in PGD according to PG-13 diagnostic criteria. Discussion: A substantial proportion of the participants met the PG-13 criteria for PGD, emphasizing that therapeutic services are indispensable in this population. The associated factors for PGD found in our Arab-speaking sample are largely consistent with those found in studies from other regions. The slightly differing numbers of associated factors between the linear and logistic regression underline that a continuous score reflects the continuum between normal and dysfunctional grieving, and therefore also a range of factors associated with PGD.

description: Rotational Drift Spectroscopy (RDS) is a novel spectroscopic method for magnetic nanoparticles. It is based on measuring the rotational drift of magnetic nanoparticle ensembles in a rotating magnetic field, which is below the magnetic field strength necessary for rotating the magnetic nanoparticles synchronously. Magnetorelaxometry (MRX) measures the decaying magnetization after applying a magnetic pulse, allowing to determine the zero-field relaxation time of magnetic particle systems. It is used, e.g., for general particle characterization or bioassay applications. The following work presents pulsed RDS sequences for measuring the zero-field relaxation behavior of magnetic particles. Measuring the zero-field relaxation using an RDS setup provides the advantage of allowing the combination of additional measurement sequences for more specific particle characterizations. The pulse sequence can be tailored to the necessary relaxation time range of the particle system, allowing to cover a wide range of different relaxation times.

description: Using the techniques introduced by Corvaja and Zannier we solve the non-split case of the geometric Lang-Vojta Conjecture for affine surfaces isomorphic to the complement of a conic and two lines in the projective plane. In this situation we deal with sections of an affine threefold fibered over a curve, whose boundary, in the natural projective completion, is a quartic bundle over the base whose fibers have three irreducible components. We prove that the image of each section has bounded degree in terms of the Euler Characteristic of the base curve.

description: The neutrino induced hyperon production processes $\barν_{e/μ} + p \to e^+/μ^+ + π+ Λ/Σ$ may provide a unique clean place for studying low energy $πΛ/Σ$ interaction and hyperon resonances below $KN$ threshold. The production rates for some neutrino induced hyperon production processes are estimated with theoretical models. Suggestions are made for the study of hyperon production from neutrino-nucleon reaction at present and future neutrino facilities.

description: Magnetic particle imaging (MPI) provides background-free images of magnetic nanoparticle distribution. MPI would benefit from an additional imaging technique that reveal the anatomical background information, required in many applications. Here, we present a simulation study based on our in-house open-sided prototype MPI system, in which the coils can be utilized interchangeably for MPI and MRI data acquisitions. The system can provide a selection field gradient of 0.5 T/m for MPI in field free line topology, and B0 field of up to 50 mT for MRI. We analyze the system-induced deviations on MRI images for different B0 values and pulse sequence parameters.

description: Transmission spectroscopy is a prime technique to study the chemical composition and structure of exoplanetary atmospheres. Strong excess absorption signals have been detected in the optical Na I D1, 2 Fraunhofer lines during transits of hot Jupiters, which are attributed to the planetary atmospheres and allow us to constrain its structure. We study the atmosphere of WASP-7 b by means of high-resolution transit spectroscopy in the sodium lines. We analyzed a spectral transit time series of 89 high-resolution spectra of the hot Jupiter WASP-7 b that was observed using the Ultraviolet and Visual Echelle Spectrograph (UVES). We used the telluric lines for an accurate alignment of the spectra and carry out a telluric correction with molecfit. Stellar magnetic activity was monitored by investigating chromospheric lines such as the Ca II H and K and hydrogen H$α$ lines. Finally, we obtained transmission spectra and light curves for various lines. The star shows no identifiable flares and, if any, marginal changes in activity during our observing run. The sodium transmission spectra and corresponding light curves clearly show signs of the Rossiter-McLaughlin effect (RM) and the stellar center-to-limb variation (CLV) that we modeled using synthetic spectra. A statistically significant, narrow absorption feature with a line contrast of 0.50$\pm$0.06% (at $\sim 8.3σ$ level) and a full width at half maximum (FWHM) of 0.13$\pm$0.02 A is detected at the location of the Na I D$_2$ line. For the Na I D$_1$ line signal, we derived a line contrast of 0.13$\pm$0.04% (at $\sim 3.2σ$ level), which we consider a tentative detection. In addition, we provide upper limits for absorption by the hydrogen Balmer lines (H$α$, H$β$, and H$γ$), K I $λ$7699 A, Ca II H and K, and infra-red triplet (IRT) lines.

description: In this article we bound the number of remarkable values of a polynomial vector field. The proof is short and based on Jouanolou's theorem about rational first integrals of planar polynomial derivations. Our bound is given in term of the size of a Newton polygon associated to the vector field. We prove that this bound is almost reached.

description: Global transport sector is the third largest contributor of greenhouse gas emissions. Governments around the world as well other global stakeholders realize the intensity of the situation and are transitioning towards zero or low-emissions transportation modes in order to reduce greenhouse gas emissions and stop climate change. While the global electric vehicle (EV) adoption is on rise, developing countries like Pakistan have been facing many obstacles in the face of EV adoption such as shortfall of electricity, high EV prices, low average income and absence of commercial and residential charging infrastructure. This thesis proposes a design of a micro solar electric vehicle, which would address the existing challenges and provide an economical yet feasible solution. The design and system sizing of the micro solar EV was done in HOMER Pro. Based on the techno-economic feasibility analysis completed in HOMER, a dynamic model of the micro solar EV was created in Simulink. This comprehensive model includes PV generation, maximum power point tracking, battery charging and discharging, DC-motor operation and speed control of the electric vehicle, while taking into consideration environmental factors like irradiance and temperature. Moreover, a detailed ready to build, instrumentation and control design of the car was developed in Tinkercad. The Tinkercad model was divided into two parts with the first part covering the control and monitoring circuit for the vehicle, and the second part covering the auxiliary circuit for the vehicle. Lastly, conclusions are provided based on the research conducted in each section of this thesis, and areas for future research have been identified.
