description: We report the realization of an ultra-efficient low-temperature hybrid heat current rectifier, thermal counterpart of the well-known electric diode. Our design is based on a tunnel junction between two different elements: a normal metal and a superconducting island. Electronic heat current asymmetry in the structure arises from large mismatch between the thermal properties of these two. We demonstrate experimentally temperature differences exceeding $60$ mK between the forward and reverse thermal bias configurations. Our device offers a remarkably large heat rectification ratio up to $\sim 140$ and allows its prompt implementation in true solid-state thermal nanocircuits and general-purpose electronic applications requiring energy harvesting or thermal management and isolation at the nanoscale.

description: Let $\mathcal A$ be an elliptic tensor. A function $v\in L^1(I;LD_{div}(B))$ is a solution to the non-stationary $\mathcal A $-Stokes problem iff \begin{align}\label{abs} \int_Q v\cdot\partial_tϕ\,dx\,dt-\int_Q \mathcal A(\varepsilon(v),\varepsilon(ϕ))\,dx\,dt=0\quad\forallϕ\in C^{\infty}_{0,div}(Q), \end{align} where $Q:=I\times B$, $B\subset\mathbb R^d$ bounded. If the l.h.s. is not zero but small we talk about almost solutions. We present an approximation result in the fashion of the $\mathcal A$-caloric approximation for the non-stationary $\mathcal A $-Stokes problem. Precisely, we show that every almost solution $v\in L^p(I;W^{1,p}_{div}(B))$, $1

description: Objectives: Farmworkers disproportionately experience preventable adverse health effects from heat exposure. We sought to evaluate the effect of participatory heat education on farmworker knowledge. Methods: We conducted a parallel, comparison group intervention study to investigate the effectiveness of a Spanish/English participatory, culturally-tailored, heat education-based intervention on farmworker heat knowledge in the Summer 2019. We used convenience sampling to recruit adult outdoor farmworkers from Central/Eastern Washington State, USA. Crews were randomized to receive the intervention (n = 40 participants) versus not receive the intervention (n = 43 participants). We assessed changes in heat knowledge, scored on a scale from 0 to 11, between baseline, immediate post-intervention, and post-season, which was approximately three months after baseline, using the Wilcoxon signed-rank test. We compared differences in knowledge scores from baseline to post-season between groups using analysis of variance. Results: Average knowledge scores improved from 4.6 (standard deviation [sd] 1.5) to 6.3 (sd 2.0) pre to post season in the intervention group (p < 0.001). There was a greater improvement in pre-post knowledge scores in the intervention (average difference 1.6, sd 2.0) versus the comparison group (average difference 0.41, sd 1.7) (p = 0.04). Conclusions: Participatory heat training was effective in improving farmworker heat knowledge over the course of a summer season. Results of this study will be used to guide heat prevention efforts for farmworkers. Trial registration: ClinicalTrials.gov Registration Number: NCT04234802

Finite Type Invariants of w-Knotted Objects I: w-Knots and the Alexander Polynomial

description: This is the first in a series of papers studying w-knotted objects (w-knots, w-braids, w-tangles, etc.), which make a class of knotted objects which is {w}ider but {w}eaker than their usual counterparts. The group of w-braids was studied (as "{w}elded braids") by Fenn-Rimanyi-Rourke and was shown to be isomorphic to the McCool group of "basis-conjugating" automorphisms of a free group Fn. Brendle-Hatcher, tracing back to Goldsmith, have shown this group to be a group of movies of flying rings in R3. Satoh studied several classes of w-knotted objects (as "{w}eakly-virtual") and has shown them to be closely related to certain classes of knotted surfaces in R4. So w-knotted objects are algebraically and topologically interesting. Here we study finite type invariants of w-knotted objects. Following Berceanu-Papadima, we construct homomorphic universal finite type invariants ("expansions") of w-braids and of w-tangles. We find that the universal finite type invariant of w-knots is essentially the Alexander polynomial. We find that the spaces Aw of "arrow diagrams" for w-knotted objects are related to not-necessarily-metrized Lie algebras. Many questions concerning w-knotted objects turn out to be equivalent to questions about Lie algebras. Most notably we find that a homomorphic expansion of w-knotted foams is essentially the same as a solution of the Kashiwara-Vergne conjecture (KV), thus giving a topological explanation to the work of Alekseev-Torossian work on KV and Drinfel'd associators. The true value of w-knots, though, is likely to emerge later, for we expect them to serve as a {w}armup example for the study of virtual knots. We expect v-knotted objects to provide the global context whose associated graded structure will be the Etingof-Kazhdan theory of quantization of Lie bialgebras.

Die Stärkung des Kohärenzsinns in der sozialarbeiterischen Praxis mit jungen Erwachsenen in Erwerbslosigkeit: Salutogene Handlungsansätze in der Praxis der Sozialhilfe und des Motivationssemesters
Creators: name: Bättig, Melanie
Publisher: name: Zenodo
Year: 2022

description: Junge Erwachsene in Erwerbslosigkeit befinden sich in einer prekären Lebenslage und stellen eine Herausforderung im Praxisalltag der Sozialen Arbeit dar. Die vorherrschenden Handlungsmaximen, welche eine Motivationssteigerung durch Beschäftigungsprogramme aber auch durch Anreize und Sanktionen erzeugen wollen, sind mässig erfolgreich. Mit der Erwerbslosigkeit geht oftmals ein schlechter psychischer Gesundheitszustand einher. Das wiederholte Erleben von Ablehnung und Scheitern auf dem Weg in die Berufswelt zeigt sich in einem reduzierten Selbstwertgefühl und Resignation bei den jungen Erwachsenen. Die Salutogenese, mit den generalisierten Widerstandsressourcen und dem Kohärenzsinn als zentrale Konzepte, kann hier eine neue Perspektive auf die herausfordernde Situation bieten. Auf dieser Grundlage geht die Bachelorarbeit der Frage nach, wie im Praxisfeld der Sozialhilfe und des Motivationssemesters der Kohärenzsinn der jungen Erwachsenen gestärkt werden kann. In der Literaturarbeit werden Möglichkeiten dargestellt, wie dies durch eine Fokussierung auf die Dimensionen der Verstehbarkeit, Handhabbarkeit und Bedeutsamkeit gelingen kann. Die Berücksichtigung der Lebenswelt der jungen Erwachsenen, die Stärkung ihrer internen und externen Ressourcen sowie das Vertrauen in ihre Fähigkeiten, sollen es den jungen Erwachsenen ermöglichen, an den Herausforderungen zu wachsen und gestärkt in die Erwerbswelt einzutreten.

description: We point out that the hypothesis of a SU(5)-like supersymmetric Grand Unified Theory (GUT) implies a generic relation within the flavour structure of up-type squarks. Contrary to other well-known SU(5) relations between the down-quark and charged lepton sectors, this relation remains exact in the presence of any corrections and extra operators. Moreover it remains valid to a good precision at the electroweak scale, and opens thus new possibilities for testing SU(5)-like GUTs. We derive the low-energy effective theory of observable light up-type squarks, that also constitutes a useful tool for squark phenomenology. We use this effective theory to determine how to test SU(5) relations at the LHC. Focussing on scenarios with light stops, compatible with Natural SUSY, it appears that simple tests involving ratios of event rates are sufficient to test the hypothesis of a SU(5)-like GUT theory. The techniques of charm-tagging and top-polarimetry are a crucial ingredient of these tests.

description: Diese Arbeit soll den Lesenden einen Einblick in die Ökonomie und die Offene Kinder- und Jugendarbeit bieten und gegebenenfalls zum Nachdenken und Hinterfragen anregen. Die vorliegende Arbeit beschäftigt sich mit dem Themenfeld der Ökonomisierung. Ziel ist es, aufzuzeigen, inwiefern die Tendenz zum Wirtschaften vermehrt auch in der Offenen Kinder- und Jugendarbeit sicht- und spürbar wird. Die Literaturarbeit geht der Frage nach, welche Spannungsfelder zwischen den Prinzipien der Offenen Kinder- und Jugendarbeit und der Ökonomie herausgearbeitet werden können und was dies für die Fachpersonen und deren Arbeit bedeutet. Ein Schwerpunkt liegt dabei auf der Gegenüberstellung der Prinzipien beziehungsweise der charakteristischen Eigenschaften beider Themenfelder. Mithilfe der modalen Strukturierungstheorie sollen die Begrifflichkeiten gegliedert und sortiert werden. Mit dem praxisnahen Kreuzbändermodell werden die Prinzipien aufgeschlüsselt, analysiert und ein Fazit wird gezogen. Einen weiteren Schwerpunkt stellen die Kernaussagen dar. Das sind Themen, die der Autorin während der Bearbeitung besonders aufgefallen sind und die in einer Zielsetzung, die zur Sensibilisierung anregen soll, enden.

description: We demonstrate in open microcavities with broken chiral symmetry, quasi-degenerate pairs of co-propagating modes in a non-rotating cavity evolve to counter-propagating modes with rotation. The emission patterns change dramatically by rotation, due to distinct output directions of CW and CCW waves. By tuning the degree of spatial chirality, we maximize the sensitivity of microcavity emission to rotation. The rotation-induced change of emission is orders of magnitude larger than the Sagnac effect, pointing to a promising direction for ultrasmall optical gyroscopes.

description: Psychische Erkrankungen sind bio-psycho-sozial bedingt. Die Gesundheit von Menschen ist daher geprägt durch die Lebensbedingungen, in welche sie hineingeboren werden. In Organisationen im Kontext der Sozialen Arbeit kommen in der Schweiz vermehrt Peer-Fachpersonen zum Einsatz. Die Peer-Arbeit ist als eine Ergänzung zur herkömmlichen Begleitung und Behandlung durch Fachpersonen zu verstehen. Aus der Fachliteratur und den Befragungen resultiert durch die Zusammenarbeit mit Peers eine Vielzahl positiver Effekte für Menschen mit psychischen Erkrankungen. Peer-Fachpersonen zeichnen sich in der Begleitung von Betroffenen durch ihre Erfahrungsexpertise von psychischen Krisen aus, womit sie sich von Fachpersonen unterscheiden und gleichzeitig mit ihrer Tätigkeit in Organisationen eine grosse Bereicherung schaffen. Eine grössere Herausforderung scheint eine gelingende Implementierung der Peers darzustellen, da sich die Erfahrungen für eine optimale interprofessionelle Kooperation mit Fachpersonen im deutschsprachigen Raum noch geringhalten. Das Ziel der vorliegenden Bachelorarbeit sind die Chancen und Herausforderungen der Peer-Arbeit aus der Fachliteratur herauszuarbeiten. Das Forschungskapitel beinhaltet vier Befragungen von Peers mithilfe von leitfadengestützten Expert*inneninterviews. Die Auswertung er­ folgte nach der Methode von Mühlfeld et al. Daraus resultieren im Schlusskapitel Empfehlungen für die Profession der Sozialen Arbeit, welche eine erfolgreiche Implementierung von Peers in Organisationen im Kontext der Sozialen Arbeit beschreibt und dadurch eine gelingende Zusammenarbeit mit Professionellen ermöglicht.

description: We investigate the possible origin of extended emissions (EEs) of short gamma-ray bursts with an isotropic energy of ~ 10^(50-51) erg and a duration of a few 10 s to ~ 100 s, based on a compact binary (neutron star (NS)-NS or NS-black hole (BH)) merger scenario. We analyze the evolution of magnetized neutrino-dominated accretion disks of mass ~ 0.1 M_sun around BHs formed after the mergers, and estimate the power of relativistic outflows via the Blandford-Znajek (BZ) process. We show that a rotation energy of the BH up to > 10^52 erg can be extracted with an observed time scale of > 30 (1+z) s with a relatively small disk viscosity parameter of alpha < 0.01. Such a BZ power dissipates by clashing with non-relativistic pre-ejected matter of mass M ~ 10^-(2-4) M_sun, and forms a mildly relativistic fireball. We show that the dissipative photospheric emissions from such fireballs are likely in the soft X-ray band (1-10 keV) for M ~ 10^-2 M_sun possibly in NS-NS mergers, and in the BAT band (15-150 keV) for M ~ 10^-4 M_sun possibly in NS-BH mergers. In the former case, such soft EEs can provide a good chance of ~ 6 yr^-1 for simultaneous detections of the gravitational waves with a ~ 0.1 deg angular resolution by soft X-ray survey facilities like Wide-Field MAXI.

description: It is shown that the strong Coulomb coupling in intrinsic suspended semiconducting transition metal dichalcogenides can exceed the critical value needed for an excitonic ground state. The dipole-allowed optical excitations then correspond to intra-excitonic transitions such that the optically bright excitonic transitions near the Dirac points have a $p$-like symmetry whereas the $s$-like states are dipole forbidden. The large intrinsic coupling strength seems to be a generic property of the semiconducting transition metal dichalcogenides and strong Coulomb-coupling signatures in the form of the optical selection rules can be observed even in samples grown on typical substrates like SiO$_2$. For the examples of WS$_2$ and WSe$_2$, excellent agreement of the computed excitonic resonance energies with recent experiments is demonstrated.

The representation theory of these metaplectic tori has been developped to some extent in the works of M. Weissman, G. Savin, W. T. Gan, P. McNamara and others. In this paper we propose a geometrization of this theory in the framework of the geometric Langlands program (in the everywhere nonramified case).

description: Die vorliegende Bachelorarbeit behandelt die Fragestellung, wie die Sozialpädagogik trans Jugendliche in der stationären Jugendhilfe unterstützen kann. Anhand einer Auseinandersetzung mit aktueller Fachliteratur wird das Thema Transidentität erschlossen und mithilfe des Konzepts der Lebensbewältigung wird die Situation von trans Jugendlichen in stationären Jugendhilfen als Bewältigungslage eingeordnet und analysiert. Transidentität wird als eine Lebenslage verstanden, die dann zum kritischen Lebensereignis wird, wenn trans Menschen nicht mehr über genügend Spielraum verfügen, um die eigene Lebenslage zu gestalten und sie dadurch in ihrer Handlungsfähigkeit bedroht werden. Es wird empfohlen, dass stationäre Jugendhilfen die Zugänglichkeit ihres Angebotes für trans Jugendliche sicherstellen, eine sichere Infrastruktur für trans Jugendliche bereitstellen sowie eine transinklusive Sprache verwenden. Sozialpädagog*innen sollen spezifisches Fachwissen über Transidentität erwerben, um ihre Genderkompetenz zu erweitern, eine transaffirmative Haltung einnehmen und heteronormative Geschlechtskategorien im Alltag überschreiten, so dass vielfältige Lebensweisen möglich werden. Bei der Arbeit mit trans Jugendlichen müssen Internalisierungen von Transphobie reflektiert und ein Schutz vor jeglichen Formen der Diskriminierung sichergestellt werden. Trans Jugendliche sollen darin unterstützt werden, sich sozial einzubinden und Zugänge zu trans Communities zu erhalten. Weiter kann die Sozialpädagogik eine vermittelnde Rolle bei der Zusammenarbeit mit Eltern und gegebenenfalls medizinischen Fachpersonen einnehmen.

description: Charged Lifshitz black holes for the Einstein-Proca-Maxwell system with a negative cosmological constant in arbitrary dimension $D$ are known only if the dynamical critical exponent is fixed as $z=2(D-2)$. In the present work, we show that these configurations can be extended to much more general charged black holes which in addition exist for any value of the dynamical exponent $z>1$ by considering a nonlinear electrodynamics instead of the Maxwell theory. More precisely, we introduce a two-parametric nonlinear electrodynamics defined in the more general, but less known, so-called $(\mathcal{H},P)$-formalism and obtain a family of charged black hole solutions depending on two parameters. We also remark that the value of the dynamical exponent $z=D-2$ turns out to be critical in the sense that it yields asymptotically Lifshitz black holes with logarithmic decay supported by a particular logarithmic electrodynamics. All these configurations include extremal Lifshitz black holes. Charged topological Lifshitz black holes are also shown to emerge by slightly generalizing the proposed electrodynamics.
Erinnerungsinseln: Biografiearbeit bei Menschen im Alter mit einer kognitiven Beeinträchtigung und einer Alzheimer-Demenz im stationären Wohnen

description: Die heutige Gesellschaft durchläuft einen demografischen Wandel, welcher auch im stationären Wohnen der Behindertenhilfe bemerkbar wird. Menschen mit einer kognitiven Beeinträchtigung werden stetig älter und erreichen zusehends ein hohes Lebensalter. Dies begünstigt die Risiken an einer Alzheimer-Demenz zu erkranken. Entsprechend ist daher in Zukunft mit einer steigenden Anzahl an demenziellen Erkrankungen in den stationären Einrichtungen zu rechnen. Die Soziale Arbeit steht mit einem komplexen und individuellen Personenkreis in Berührung, welcher empirisch wenig erforscht ist. Eine Alzheimer-Demenz wirkt sich nicht nur medizinisch, sondern auch emotional einschneidend auf den Lebensalltag und auf die Umwelt von Menschen mit einer kognitiven Beeinträchtigung aus. Nebst einem fortschreitenden Abbau des Gedächtnisses und drohendem Erinnerungs- und Identitätsverlust, sind die Beteiligten auch mit einer Gefühlswelt konfrontiert, welche einen erhöhten Bedarf an emotionalem Halt und Sicherheit erfordert. Die vorliegende Fachliteraturarbeit untersucht den Personenkreis, den Umgang mit ihnen und die Herausforderungen, die sich der Sozialen Arbeit und ihren Adressat:innen stellen. Anschliessend wird der Bogen zur Biografiearbeit gespannt. Es wird erörtert, weshalb biografisches Arbeiten sinnvoll sein kann. Am Ende wird die praktische Umsetzung der Biografiearbeit untersucht. Die Voraussetzungen und Schwierigkeiten einer gelingenden Umsetzung werden geklärt und mit praktischen Methoden und Hilfsmitteln ergänzt. Innerhalb der Arbeit wurden dazu zwei Expertinnengespräche hinzugezogen, um Erkenntnisse mit praktischem und theoretischem Wissen zusätzlich zu ergänzen und zu untermauern.

description: We show that the timed Dicke states of a collection of three-level atoms can form a tight-binding lattice in momentum space. This lattice, coined the superradiance lattice (SL), can be constructed based on electromagnetically induced transparency (EIT). For a one-dimensional SL, we need the coupling field of the EIT system to be a standing wave. The detuning between the two components of the standing wave introduces an effective uniform force in momentum space. The quantum lattice dynamics, such as Bloch oscillations, Wannier-Stark ladders, Bloch band collapsing and dynamic localization can be observed in the SL. The two-dimensional SL provides a flexible platform for Dirac physics in graphene. The SL can be extended to three and higher dimensions where no analogous real space lattices exist with new physics waiting to be explored.

description: Hassett's moduli spaces of weighted stable curves form an important class of alternate modular compactifications of the moduli space of smooth curves with marked points. In this article we define a tropical analogue of these moduli spaces and show that the naive set-theoretic tropicalization map can be identified with a natural deformation retraction onto the non-Archimedean skeleton. This result generalizes work of Abramovich, Caporaso, and Payne treating the Deligne-Knudsen-Mumford compactification of the moduli space of smooth curves with marked points. We also study tropical analogues of the tautological maps, investigate the dependence of the tropical moduli spaces on the weight data, and consider the example of Losev-Manin spaces.

description: The car-sharing demand is continuously developing and lately it has evolved even more widespread than car right. However, the classic car-sharing scheme is founded on a centralized database server which can often lead to cracker attacks or password leaks. As noticed nowadays from a lot of use matters, the best solution to these challenging issues is to use blockchain technology. Blockchain as a decentralized, immutable, public ledger provides customers with security that is impossible to tamper with. A blockchain is basically a digital ledger of trades that is replicated and spread across the entire web of computer systems on the blockchain. User’s data is sensitive and crucial, and blockchain can significantly change how user’s critical information is viewed, by creating a record that can’t be altered and is encrypted end-to-end, blockchain helps prevent fraud and unauthorized activity. The previous research's many flaws were revealed with a quick skim. The existing systems offered a solution to develop and implement peer-to-peer short-term car-sharing applications founded on blockchain technology and smart contracts. For the execution of smart contracts, the Solidity programming language is used. Solidity works with the Ethereum blockchain. The fundamental originality of this system is presenting a peer-to-peer car-sharing service without a central authority, which reﬂects a decrease in costs and an increase in data clarity in that system. Also, token-based solutions give us the power to protect business-to-business (B2B) and business-to-customer (B2C) use cases.

description: In combinatorial topology we aim to triangulate manifolds such that their topological properties are reflected in the combinatorial structure of their description. Here, we give a combinatorial criterion on when exactly triangulations of 3-manifolds with transitive cyclic symmetry can be generalised to an infinite family of such triangulations with similarly strong combinatorial properties. In particular, we construct triangulations of Seifert fibred spaces with transitive cyclic symmetry where the symmetry preserves the fibres and acts non-trivially on the homology of the spaces. The triangulations include the Brieskorn homology spheres $Σ(p,q,r)$, the lens spaces $\operatorname{L} (q,1)$ and, as a limit case, $(\mathbf{S}^2 \times \mathbf{S}^1)^{\# (p-1)(q-1)}$.

description: Consider two bounded domains $Ω$ and $Λ$ in $\mathbb{R}^{2}$, and two sufficiently regular probability measures $μ$ and $ν$ supported on them. By Brenier's theorem, there exists a unique transportation map $T$ satisfying $T_\#μ=ν$ and minimizing the quadratic cost $\int_{\mathbb{R}^{n}}|T(x)-x|^{2}dμ(x)$. Furthermore, by Caffarelli's regularity theory for the real Monge--Ampère equations, if $Λ$ is convex, $T$ is continuous. We study the reverse problem, namely, when is $T$ discontinuous if $Λ$ fails to be convex? We prove a result guaranteeing the discontinuity of $T$ in terms of the geometries of $Λ$ and $Ω$ in the two-dimensional case. The main idea is to use tools of convex analysis and the extrinsic geometry of $\partialΛ$ to distinguish between Brenier and Alexandrov weak solutions of the Monge--Ampère equation. We also use this approach to give a new proof of a result due to Wolfson and Urbas. We conclude by revisiting an example of Caffarelli, giving a detailed study of a discontinuous map between two explicit domains, and determining precisely where the discontinuities occur.

description: The lowest energy configurations of short odd open chains with classical spins are determined for antiferromagnetic bilinear and biquadratic nearest-neighbor exchange interactions. The zero field residual magnetization generates differences with the magnetic behavior of even chains, as the odd chain is like a small magnet for weak magnetic fields. The lowest energy configuration is calculated as a function of the total magnetization M, even for M less than the zero field residual magnetization. Analytic expressions and their proofs are provided for the threshold magnetic field needed to drive the system away from the antiferromagnetic configuration and the spin polar angles in its vicinity, when the biquadratic interaction is relatively weak. They are also given for the saturation magnetic field and the spin polar angles close to it. Finally, an analytic expression along with its proof is given for the maximum magnetization in zero magnetic field for stronger biquadratic interaction, where the lowest energy configuration is highly degenerate.

description: Percolation is a paradigmatic model in disordered systems and has been applied to various natural phenomena. The percolation transition is known as one of the most robust continuous transitions. However, recent extensive studies have revealed that a few models exhibit a discontinuous percolation transition (DPT) in cluster merging processes. Unlike the case of continuous transitions, understanding the nature of discontinuous phase transitions requires a detailed study of the system at hand, which has not been undertaken yet for DPTs. Here we examine the cluster size distribution immediately before an abrupt increase in the order parameter of DPT models and find that DPTs induced by cluster merging kinetics can be classified into two types. Moreover, the type of DPT can be determined by the key characteristic of whether the cluster kinetic rule is homogeneous with respect to the cluster sizes. We also establish the necessary conditions for each type of DPT, which can be used effectively when the discontinuity of the order parameter is ambiguous, as in the explosive percolation model.

Meson exchange effects in elastic $ep$ scattering at loop level and the electromagnetic form factors of the proton

description: A new form of two-photon exchange(TPE) effect is studied to explain the discrepancy between unpolarized and polarized experimental data in elastic $ep$ scattering. The mechanism is based on a simple idea that apart from the usual TPE effects from box and crossed-box diagrams, the mesons may also be exchanged in elastic $ep$ scattering by two-photon coupling at loop level. The detailed study shows such contributions to reduced unpolarized cross section ($σ_{un}$) and polarized observables ($P_t,P_l$) at fixed $Q^2$ are only dependent on proton's electromagnetic form factors $G_{E,M}$ and a new unknown universal parameter $g$. After combining this contribution with the usual TPE contributions from box and crossed-box diagrams, the ratio $μ_pG_E/G_M$ extracted from the recent precise unpolarized and polarized experimental data can be described consistently.

Meshfree Note - Point Interpolation Method (PIM)

description: The point interpolation method (PIM) is a meshfree method used for fitting a curve based on a set of nodal values at specified locations. The PIM uses polynomial interpolation to fit the curve, and the number of polynomial terms required increases with the number of nodes involved. When the distribution of nodes follows a polynomial curve, the PIM can accurately fit these nodes without difficulty. However, when the nodes are distributed arbitrarily, the PIM may have instability issues, especially when many nodes are involved. To establish the PIM formulation, we begin with a polynomial representation of a function in a 1D system. We link each nodal value that we have to the fitted function using a general form, and obtain a matrix of shape functions. By multiplying the shape function matrix with the nodal values, we can obtain a fitted curve. To produce a continuous fitted curve, we create a spatial variable and obtain a shape function matrix. The implementation codes for these steps are provided in the article, including MATLAB codes that allow us to try any number of given curve nodes and observe the performance of the PIM in fitting the curve. It's important to note that the number of unknowns must be equal to the number of given nodes in the PIM. By solving for these unknowns, we can obtain a general fitted function that yields a continuous interpolated function along x, based on given nodal values at specified locations. Overall, the PIM is a useful method for fitting curves based on a set of nodal values. Its simplicity and flexibility make it a popular choice in many applications. However, it's important to be aware of the limitations of the PIM, particularly with regards to instability issues when many nodes are involved.

description: Let $r$ be a positive integer. An $r$-set is a pair $X= (V(X),R(X))$ consisting of a set $V(X)$ with a subset $R(X)$ of the direct product $V(X)^r$. The object of this paper is to investigate the Hom complexes of $r$-sets, which were introduced for graphs in the context of the graph coloring problem. In the first part, we introduce simplicial sets which we call singular complexes, and show that singular complexes and Hom complexes are naturally homotopy equivalent. The second part is devoted to the generalization of $\times$-homotopy theory established by Dochtermann. We show the folding theorem for hypergraphs which was partly proved by Iriye and Kishimoto.

description: Families of m-jet spaces and arc spaces. Let V be an algebraic variety defined over an algebraically closed field of characteristic zero. The m-jet spaces and the arc space provide the information on the geometry of the variety V, therefore it is natural to ask the following questions: When will a deformation of V induce a deformation of the m-jet spaces and the arc space? If one considers a deformation of V which admits a flat simultaneous resolution, how will the image of the Nash application vary? In section 3 some partial answers to these questions can be found. In section 4 two families of hypersurfaces of the 4-dimensional affine space are shown in which the Nash application is bijective. What's more, in each case a desingularization in which all the irreducible components of the exceptional fiber are essential divisors is explicitly given. It is important to note that very few examples of this type are found in the literature.

Kinder und ihre hochstrittigen Eltern: Wie Abklärungsverfahren mit hochstrittigen Eltern deeskalierend und zum Wohl des Kindes gestaltet werden können.

Publisher: name: Zenodo

description: Das Verhalten hochstrittiger Trennungs- und Scheidungseltern kann verschiedene weitreichende Folgen für Kinder haben. Kinder können durch die lange andauernden elterlichen Konflikte stark belastet und in ihrem Wohl gefährdet werden. Stellen die massiven elterlichen Konflikte eine Kindeswohlgefährdung dar oder müssen kindesrechtliche Belange geregelt werden, führt die Kindes- und Erwachsenenschutzbehörde (KESB) ein Abklärungsverfahren durch. Die Arbeit mit hochstrittigen Eltern kann für die involvierten Fachpersonen eine grosse Herausforderung darstellen. Es soll der Frage nachgegangen werden, wie kindesschutzrechtliche Abklärungsverfahren mit hochstrittigen Eltern deeskalierend und zum Wohl des Kindes gestaltet werden können. Dies geschieht durch das Aufzeigen verschiedener Merkmale der Hochstrittigkeit und deren Auswirkungen auf das Kind und die Eltern, dem Vorstellen der rechtlichen Ausgangslage bei der KESB sowie der Auseinandersetzung mit verschiedenen Methoden in der Zusammenarbeit mit hochstrittigen Eltern. Die Fragestellung wurde anhand einer Literaturarbeit mit dem Titel «Kinder und ihre hochstrittigen Eltern in kindesschutzrechtlichen Abklärungsverfahren» bearbeitet. Durch Fachkenntnisse über Hochstrittigkeit und dem Bestimmen des elterlichen Konfliktniveaus werden methodisches Vorgehen und passende Interventionen innerhalb des gesetzlichen Rahmens abgeleitet, welche das Kind wieder ins Zentrum rücken und deeskalierend wirken können. Eine allgemein gültige Vorgehensweise kann in dieser Arbeit nicht aufgezeigt werden, da jeder Fall individuell zu betrachten ist und massgeblich von den Eltern und ihrem Verhalten abhängig ist.
