  abstract     = {{When joining lightweight parts of various materials, clinching is a cost efficient solution. In a production line, the quality of a clinch point is primarily controlled by measurement of dimensions, which are accessible from outside. However, methods such as visual testing and measuring the bottom thickness as well as the outer diameter are not able to deliver any information about the most significant geometrical characteristic of the clinch point, neck thickness and undercut. Furthermore, ex-situ destructive methods such as microsectioning cannot detect elastic deformations and cracks that close after unloading. In order to exceed the current limits, a new non-destructive in-situ testing method for the clinching process is necessary. This work proposes a concept to characterize clinch points in-situ by combining two complementary non-destructive methods, namely, computed tomography (CT) and ultrasonic testing. Firstly, clinch points with different geometrical characteristics are analysed experimentally using ex-situ CT to get a highly spatially resolved 3D-image of the object. In this context, highly X-ray attenuating materials enhancing the visibility of the sheet-sheet interface are investigated. Secondly, the test specimens are modelled using finite element method (FEM) and a transient dynamic analysis (TDA) is conducted to study the effect of the geometrical differences on the deformation energy and to qualify the TDA as a fast in-situ non-destructive method for characterizing clinch points at high temporal resolution. }},

  abstract     = {{Given the pandemic-induced school lockdown in Germany in the spring of 2020, COVID-19 evidently had a negative impact on child and adolescent mental health and wellbeing. However, there is no evidence regarding the specific problems of students with special educational needs in emotional and behavioral disorders (E/BD) during or after the school lockdown. Thus, this study bridges the gap. A sample of 173 students across Germany was included in the analysis. The students were rated by their teachers in an online survey via a standardized teacher-report form for emotional and behavioral problems and competencies, as well as perceptions of inclusion. Several student- and teacher-level predictors were applied in a stepwise regression analysis. The results showed that the school lockdown marginally impacted E/BD, with small differences between student groups. The strongest predicting variable was students’ psychosocial situation. Hence, the psychosocial situation of students should be monitored by teachers and school psychologists to provide sufficient support during lockdown.

By using (NH4)2TeO4 instead of TeO2, a fine powder consisting of microcrystalline spheres of K12+6xFe6Te4−xO27 was obtained. K12+6xFe6Te4−xO27 crystallizes in the acentric cubic space group Iurn:x-wiley:09476539:media:chem202102464:chem202102464-math-0001 3d. [FeIIIO5] pyramids share their apical atoms in [Fe2O9] groups and two of their edges with [TeVIO6] octahedra to form an open framework that consists of two loosely connected, but not interpenetrating, chiral networks. The flexibility of the hinged oxometalate network manifests in a piezoelectric response similar to that of LiNbO3.The potassium cations are mobile in channels that run along the <111> directions and cross in cavities acting as nodes. The ion conductivity of cold-pressed pellets of ball-milled K12+6xFe6Te4−xO27 is 2.3×10^(−4) S ⋅ cm^(−1) at room temperature. Magnetization measurements and neutron diffraction indicate antiferromagnetic coupling in the [Fe2O9] groups.}},

  abstract     = {{The conventional wisdom is that Favart's 'Soliman second' is, as Larry Wolff puts it, about an "explicitly French triumph over Ottoman despotism". This may be true to a certain extent - but it misses the point. As impressive as the depiction of the 'Oriental' may have been, it is not itself the core message of this comédie, but rather only one of the means to an end, which consists of once again accompanying and authenticating Justine Favart's novel, very modern approach to realistic character representation in the best possible way. This study demonstrates this by means of a combined analysis of the theatrical levels of text, image and music. Instead of orientalism in the sense of constructing images of the exotic 'other', the textual, pictorial and musical strategies employed in this play specifically conceived for Justine Favart apply to the production of theatrical 'authenticity' and 'natural' character representation in general. The fact that the stage persona thus brought to bear, i.e. the main character Roxelane, who responds to many models from Racine to Montesquieu, is a militantly enlightened and feminist one whose 'natural' persuasiveness and force no one can ultimately resist, so that Justine Favart's Roxelane triumphantly asserts herself all along the line and establishes nothing less than a new social, gender and state order, makes the matter all the more interesting.}},

Denote the smallest degree of a polynomial $p(X_1,\dots,X_n)$ vanishing on
$P\cap\mathbb Z^n$ by $r_P$ and denote the smallest number $u\geq0$ such that
every function on $P\cap\mathbb Z^n$ can be interpolated by a polynomial of
degree at most $u$ by $s_P$. We show that the values $(r_{d\cdot P}-1)/d$ and
$s_{d\cdot P}/d$ for dilates $d\cdot P$ converge from below to some numbers
$v_P,w_P>0$ as $d$ goes to infinity. The limits satisfy $v_P^{n-1}w_P \leq
n!\cdot\operatorname{vol}(P)$. When $P$ is a triangle in the plane, we show
equality: $v_Pw_P = 2\operatorname{vol}(P)$. These results are obtained by
looking at the set of standard monomials of the vanishing ideal of $d\cdot
P\cap\mathbb Z^n$ and by applying the Bernstein--Kushnirenko theorem. Finally,
we study irreducible Laurent polynomials that vanish with large multiplicity at
a point. This work is inspired by questions about Seshadri constants.}},
