On the Rubidium Thiotellurate(IV) Rb2[TeS3] and its Tritohydrate Rb2[TeS3] ⋅ 1/3 H2O
Authors: Wolff Klaus K. , Pfitzner Arno , Schleid Thomas 
Published: October 2024

AbstractRb2[TeS3] and Rb2[TeS3] ⋅ 1/3 H2O were obtained from rubidium azide (RbN3), tellurium and sulfur in 2 : 1 : 3 molar ratios from evacuated fused silica ampoules at 500 °C under more or less anhydrous conditions. Both compounds crystallize orthorhombically in the space group P212121 (Rb2[TeS3]: a=873.42(6) pm, b=1316.73(9) pm, c=2064.59(14) pm; Rb2[TeS3] ⋅ 1/3 H2O: a=872.97(6) pm, b=1299.82(9) pm, c=2148.26(15) pm, both at –173 °C for Z =12) and contain discrete ψ1‐tetrahedral [TeS3]2− anions (d(Te−S)=232–236 pm) in layerwise arrangements. The difference results from the water of hydration in Rb2[TeS3] ⋅ 1/3 H2O, which increases the coordination numbers of half of the six crystallographically distinct Rb+ cations from six and seven (only sulfur) to seven and almost eight by providing with oxygen from H2O an extra ligand (d(Rb−O)=290–318 pm). Red Rb2[TeS3] transforms pseudo‐topotactically into yellow Rb2[TeS3] ⋅ 1/3 H2O immediately upon contact with moist atmosphere. The compounds were screened with X‐ray diffraction, Raman and diffuse reflectance spectroscopy as well as thermal analysis.
Identifying Cultural Tourists via Computational Text Analysis and Association Rule Mining
Authors: Neuts Bart 
Published: October 2024

AbstractCultural tourism has evolved into a mass market phenomenon that contributes a sizeable portion to international tourist arrivals in Europe. Yet, exact estimates of cultural tourists are hard to come by, due both to a lack of standardized conceptualization, and a difficulty in operationalization. Mostly, estimates are based on visitor surveys, which are expensive to conduct, infrequent, and often do not allow an in-depth analysis of the phenomenon. This paper proposes an alternative analytical methodology, scraping user-generated content and applying computational text analysis and association rule mining on visitor reviews in order to establish both centrality of cultural travel motives and improve understanding of cultural tourism typologies via analysing topical associations within the reviews. The methodology is tested on 2507 reviews for the historical centre of the city of Ghent, Belgium. The results show estimates that are comparable in size to visitor survey statistics, while lending additional information on relative importance of cultural travel motivations.
Stakeholders Engagement Processes for Co-Creation of Strategic Action Plans for Circular and Human-Centred Cultural Tourism in European Heritage Sites
Authors: Ćwikła Małgorzata , Garzillo Cristina , Bosone Martina , Gravagnuolo Antonia 
Published: October 2024

AbstractSustainable cultural tourism can be a powerful means to enhance communities’ wellbeing increasing economic wealth in currently less known and remote areas, as well as residents’ awareness on local culture and cultural heritage, environmental preservation and social cohesion. However, tourism activities can threaten cultural and natural resources, especially in fragile natural & cultural areas. Sustainability-led innovation and creativity could contribute to ensure that tourism activity is conducted within a responsible framework, engaging local operators and stakeholders towards reaching shared objectives. The integration of a circular economy oriented approach in cultural tourism strategies can be beneficial to allow sustainable tourism activities which avoid depletion of natural resources, excessive greenhouse gas emissions, over-consumption of cultural resources. Local communities represent the owners and custodians of important natural and cultural resources, thus their active role in cultural tourism strategies development is fundamental to ensure their conservation, regeneration and valorisation over time. Engaging stakeholder groups already at the initial stage of designing changes, can contribute to the development of strategies aiming at implementation of community-based circular and human-centred actions in various areas. The paper describes the co-creation process conducted with various types of stakeholders in six European regions within the Horizon 2020 Be.CULTOUR project. Special attention was given to the process of activating local communities and making them co-create and co-initiative innovative solutions.
Heritage and Territory: Tangible and Intangible Cultural Resources as Drivers of Regional Development in Croatia
Authors: Kuliš Zvonimir , Šimundić Blanka 
Published: October 2024

AbstractThis paper investigates the relationship between cultural heritage, tourism demand, and regional development in Croatia using a spatial econometrics approach. A composite Cultural Heritage Index was created based on UNESCO and national material and immaterial cultural assets within the framework of the Horizon 2020 SmartCulTour project. The spatial autoregressive (SAR) model was employed to analyze the impact of cultural heritage and tourism demand on regional development across Croatian NUTS 3 regions while accounting for control variables such as gross value added and trade openness. The findings reveal that cultural heritage has a positive and statistically significant effect on regional development, both directly and indirectly. Tourism demand also plays a vital role in regional development, with the potential for enhancing positive spillover effects. These results contribute to the literature by quantitatively demonstrating the link between cultural heritage, tourism, and regional development in the Croatian context, providing valuable insights for policymakers to foster sustainable cultural tourism activities.
Historische Kontextualisierung
Authors: Kneifel Malte 
Published: October 2024

ZusammenfassungIn diesem Kapitel erfolgt eine umfassende Aufarbeitung des historischen Kontexts, in dem die in dieser Arbeit zu untersuchenden zapotekisch-spanischen Textpaare angesiedelt sind. Um der Komplexität der historischen Hintergründe gerecht zu werden, knüpft die Kontextualisierung an generelle Aspekten der Kolonisierung Mittelamerikas, der Gründung des Vizekönigreichs Neu-Spanien und davon ausgehend der Kolonisierung des Gebiets der alcaldía mayor Villa Alta an. Hiervon ausgehend werden relevante Aspekte der politischen Strukturen Neu-Spaniens erörtert, konkret das politisch-administrative System auf lokaler Ebene, die darin verortete Gesetzgebung und Rechtsprechung sowie, wiederum darin angesiedelt, die indigene Selbstverwaltung in den kolonialen indigenen Gemeinden, in deren konkretem Kontext die in dieser Arbeit zu analysierenden Texte produziert wurden und folglich zu betrachten sind.
(Indigene) juristisch-notarielle Schreibpraxis und koloniale Translationspraxis
Authors: Kneifel Malte 
Published: October 2024

ZusammenfassungDieses Kapitel thematisiert, basierend auf den Erkenntnissen aus Kapitel 2, die indigene Schreibpraxis in der juristisch-notariellen Sphäre sowie die Praxis von Translation zwischen indigenen Sprachen und dem Spanischen während der Kolonialherrschaft in Mittelamerika. Hier wird insbesondere auf die Akteursgruppe der escribanos, kolonialer Gerichtsschreiber, eingegangen. In einem weiteren Schritt wird der Faktor Translation in der juristisch-notariellen Sphäre der spanischen Kolonialherrschaft beleuchtet. Dies geht auch mit einer vor dem Hintergrund des aktuellen Forschungsstands notwendigen Erörterung der Begriffe Sprachpolitik und Translationspolitik einher. Auf dieser Basis können schließlich zentrale Akteursgruppen identifiziert und beschrieben werden, die an den kolonialen Translationsprozessen beteiligt und somit auch für den gegebenen Kontext der Textproduktion relevant waren. Vor dem Hintergrund dieses Wissens wird schließlich die Schreibpraxis und Translation im Kontext der alcaldía mayor Villa Alta umrissen, um eine historisch-kontextuelle Basis für die eigentliche Textanalyse zu schaffen.

Außerdem wird ein Sekundärkorpus aus historischen Grammatiken, Wörterbüchern und juristisch-notariellen formularios beschrieben, das dieser Arbeit zugrunde liegt und die Analyse der zapotekisch-spanischen Texte stützt.
Disentangling new physics in $$ K\to \pi \nu \overline{\nu} $$ and $$ B\to K\left({K}^{\ast}\right)\nu \overline{\nu} $$ observables
Authors: Buras Andrzej J. , Harz Julia , Mojahed Martin A.

Abstract
We investigate the possibility of disentangling different new physics contributions to the rare meson decays "Image missing" and "Image missing" through kinematic distributions in the missing energy "Image missing". We employ dimension-6 operators within the Low-Energy Effective Field Theory (LEFT), identifying the invisible part of the final state as either active or sterile neutrinos. Special emphasis is given to lepton-number violating (LNV) operators with scalar and tensor currents. We show analytically that contributions from vector, scalar, and tensor quark currents can be uniquely determined from experimental data of kinematic distributions. In addition, we present new correlations of branching ratios for K and B-decays involving scalar and tensor currents. As there could a priori also be new invisible particles in the final states, we include dark-sector operators giving rise to two dark scalars, fermions, or vectors in the final state. In this context, we present new calculations of the inclusive decay rate "Image missing" for dark operators. We show that careful measurements of kinematic distributions make it theoretically possible to disentangle the contribution from LEFT operators from most of the dark-sector operators, even when multiple operators are contributing. We revisit sum rules for vector currents in LEFT and show that the latter are also satisfied in some new dark-physics scenarios that could mimic LEFT. Finally, we point out that an excess in rare meson decays consistent with a LNV hypothesis would point towards highly flavor non-democratic physics in the UV, and could put high-scale leptogenesis under tension.
Fine Structure of Flat Bands in a Chiral Model of Magic Angles
Authors: Becker Simon , Humbert Tristan , Zworski Maciej 
Published: October 2024

AbstractWe analyse symmetries of Bloch eigenfunctions at magic angles for the Tarnopolsky–Kruchkov–Vishwanath chiral model of the twisted bilayer graphene (TBG) following the framework introduced by Becker–Embree–Wittsten–Zworski. We show that vanishing of the first Bloch eigenvalue away from the Dirac points implies its vanishing at all momenta, that is, the existence of a flat band. We also show how the multiplicity of the flat band is related to the nodal set of the Bloch eigenfunctions. We conclude with two numerical observations about the structure of flat bands.
Automorphism Groups of Deformations and Quantizations of Kleinian Singularities
Authors: Castellan Simone 
Published: October 2024

AbstractIt is known that, for the algebra of functions on a Kleinian singularity, the parameter space of deformations and the parameter space of quantizations coincide. We prove that, for a Kleinian singularity of type $$\textbf{A}$$
A
or $$\textbf{D}$$
D
, isomorphisms between the quantizations are essentially the same as Poisson isomorphisms between deformations. In particular, the group of automorphisms of the deformation and the quantization corresponding to the same deformation parameter are isomorphic. We additionally describe the groups of automorphisms as abstract groups: for type $$\textbf{A}$$
A
they have an amalgamated free product structure, for type $$\textbf{D}$$
D
they are subgroups of the groups of Dynkin diagram automorphisms. For type $$\textbf{D}$$
D
we also compute all the possible affine isomorphisms between deformations; this was not known before.
Langzeitverläufe der depressiven Erkrankung
Authors: Paetow Rebecca , Frodl Thomas 
Published: October 2024

Zusammenfassung
Hintergrund
Die Definition von Langzeitverläufen der Depression ist heterogen. Vor allem chronische und therapieresistente Verläufe bedeuten einen hohen Kostenfaktor und reduzieren Lebensqualität stark. Ausgehend von der pharmakotherapeutischen „therapieresistenten Depression“ (TRD) rücken immer mehr systemische Ansätze in den Vordergrund.

Ziel der Arbeit
Dieses narrative Review bietet eine Übersicht zu Langzeitverläufen depressiver Erkrankungen, inklusive verschiedener Definitionen und Einflussfaktoren. Zudem wird eine Übersicht zur Biomarkerforschung des Therapieansprechens mit Fokus auf zentrale Bildgebung vorgestellt.

Material und Methoden
Es erfolgte eine selektive Literaturrecherche in PubMed und Google Scholar für ein narratives Review. Besonders berücksichtigt wurden größere Kohortenstudien, systematische Reviews, Metaanalysen und Studien zur Prädiktion von Therapieansprechen.

Ergebnisse
Chronische und therapieresistente Verläufe bedeuten eine relevante Reduktion von Lebensqualität sowie erhöhte gesundheitliche Risiken. Die Erfassung des Therapieansprechens ist eine definitorische Herausforderung: Eine Alternative zur TRD bietet die systemisch orientierte „schwer zu behandelnde Depression“ („difficult-to-treat depression“, DTD). Der Fokus bewegt sich damit fort von einer Symptomreduktion hin zu einer Kontrolle des Funktionsniveaus. Biomarkerforschung für Therapieansprechen bietet Potenzial, dient derzeit aber hauptsächlich dem theoretischen Erkenntnisgewinn.

Diskussion
Die Erfassung von Langzeitverläufen depressiver Erkrankungen ist wichtig, aber auch komplex. Klinische Interventionen sollten daher ein kontinuierliches Monitoring miteinschließen und den Fokus auf den Erhalt von Lebensqualität legen.
Strengths and weaknesses of EU regional reactivity to shocks
Authors: Frassine Laura , Pontarollo Nicola , Serpieri Carolina 
Published: October 2024

AbstractThis study introduces the novel concept of regional reactivity to shocks. A region is considered to be much more reactive if it bounced back to the level of labour productivity achieved before a shock in the same or less time than it took to reach the pre-2008 economic crisis peak from an equivalent lower bound. The analysis of the reactivity of the EU-NUTS2 regions reveals a clear spatial pattern. By using a spatial lag model selected via a Bayesian comparison approach, we show that tertiary education and institutional quality are key to promote reactivity. On the other hand, population density acts in the opposite direction. Our results are potentially useful for defining policy strategies that emphasise or refocus the strengths of each region in light of current territorial trends and emerging challenges.
Towards a double bell theory of regional disparities
Authors: Capello Roberta , Cerisola Silvia 
Published: October 2024

AbstractDespite the large attention given to regional disparities, a conceptual framework simultaneously linking the inter- and intra-regional development processes over time is still missing. A vast set of empirical analyses on their trends indeed exists. In most cases, it witnesses the presence of the famous Williamson’s inverted U-shaped relation between GDP per capita and regional income inequalities, and of its augmented shape where the inverted U turns upward again at later stages of development. The paper has the aim to present a conceptual framework on the interlinkages between inter- and intra-regional disparity trends, highlighting the influence that one exerts over the other. It does so claiming that their joint analysis can provide an explanation of situations “against conventional wisdom” and can overcome the simplistic idea that if inter-regional convergence occurs, social equity is achieved. Empirical evidence is provided in the case of European regions. The paper has a normative value, in that an interpretation of the concurrent inequality trends at different levels can lead to more efficient normative interventions, avoiding misallocation of financial resources at sub-regional level.
Riemannian foliations and quasifolds
Authors: Lin Yi , Miyamoto David 
Published: October 2024

AbstractIt is well known that, by the Reeb stability theorem, the leaf space of a Riemannian foliation with compact leaves is an orbifold. We prove that, under mild completeness conditions, the leaf space of a Killing Riemannian foliation is a diffeological quasifold: as a diffeological space, it is locally modelled by quotients of Cartesian space by countable groups acting affinely. Furthermore, we prove that the holonomy groupoid of the foliation is, locally, Morita equivalent to the action groupoid of a countable group acting affinely on Cartesian space.
Generalized juggling patterns, quiver Grassmannians and affine flag varieties
Authors: Feigin Evgeny , Lanini Martina , Pütz Alexander 
Published: October 2024

Abstract
The goal of this paper is to clarify the connection between certain structures from the theory of totally nonnegative Grassmannians, quiver Grassmannians for cyclic quivers and the theory of local models of Shimura varieties. More precisely, we generalize the construction from our previous paper relating the combinatorics and geometry of quiver Grassmannians to that of the totally nonnegative Grassmannians. The varieties we are interested in serve as realizations of local models of Shimura varieties. We exploit quiver representation techniques to study the quiver Grassmannians of interest and, in particular, to describe explicitly embeddings into affine flag varieties which allow us to realize our quiver Grassmannians as a union of Schubert varieties therein.
Doxepin as OCT2 inhibitor ameliorates inflammatory response and modulates PI3K/Akt signaling associated with cisplatin-induced nephrotoxicity in rats

Published: October 2024

AbstractOrganic cationic transporter 2 (OCT2) was identified as the main transporter involved in the accumulation of cisplatin (CP) in the proximal tubular renal cells, resulting in nephrotoxicity. Doxepin (DOX) is a tricyclic agent with an inhibitory effect on OCT2. This study aimed to explore the possible mechanisms of the renoprotective role of DOX toward CP-induced nephrotoxicity. Rats were randomly divided into six groups: group 1, control; group 2, CP; groups 3, 4, and 5 were treated with graded doses of DOX (5, 10, and 20 mg/kg, respectively) intraperitoneally (ip) once daily for 10 consecutive days and group 6 was treated only with DOX (20 mg/kg). On the seventh day, a single injected dose of CP (10 mg/kg, ip) was given to the rats in groups 2–5. Seventy-two hours after CP injection, rats were sacrificed, and the kidneys were removed for histological and biochemical measurements. DOX ameliorated the CP-induced histopathological alterations. DOX significantly reduced the expression of OCT2, lipid peroxidation marker (MDA), and inflammatory cytokines, including TNF-α, IL-6, IL-1, IL-2, and IL-1β, and increased the activity of antioxidant enzymes. In addition, pre- and co-treatment with DOX significantly reduced the CP-mediated apoptotic effect by reducing the renal tissue expression of BAX and caspase-3 levels, upregulating the expression of Bcl-2, and modulating the phosphorylation of PI3K/Akt signaling cascade. DOX exerts a nephroprotective impact against CP-mediated nephrotoxicity via the inhibition of OCT2, suppression of inflammation, oxidative stress, and apoptotic markers, and modulation of PI3K/Akt signaling cascade.
Successful large-scale and long-term kelp forest restoration by culling sea urchins with quicklime and supported by crab predation

Published: October 2024

AbstractIn 2013, a large scale (70 hectare) kelp forest restoration experiment was conducted in a sea urchin barren that had been stable for 45 years. We used 200 tons of quicklime to eradicate the sea urchin population. Kelp recovered within a year in the lime-treated sites. Quickliming did not significantly affect the abundance of non-target species. Mobile kelp fauna colonized the restored kelps, but at a slower rate than kelp and other macroalgae, probably due to slower dispersal abilities. The monitoring period (2012–2021) encompassed the expansion of invasive red king crabs, which emerged as a novel predator of sea urchins. This led to a gradual decline in sea urchin populations and facilitated kelp recovery also in the control sites. This delayed recovery does not invalid the conclusions of the short-term efficiency of the quicklime treatment, but it makes it difficult to conclude about the long-term effects. The study shows that quickliming can initiate kelp recovery within large urchin barrens. We postulate that the recovery of kelps outside the limed areas was due to crab predation, and that successful kelp restoration in areas with recruitment of sea urchins depends on a persistent top-down control of the urchins.

Published: October 2024

AbstractThis study presents both numerical modeling and experimental fabrication of three different partial-reflection (PR) coatings each optimized for quantum cascade lasers (QCLs) that emit radiation in the mid-infrared range. A novel double-layer PR coating comprising silicon dioxide (SiO2) and silicon nitride (Si3N4) was proposed as a potential solution for compatibility with QCLs fabrication processes. Subsequently, the PR coating was compared with two well-known PR coatings: a single layer of aluminum oxide (Al2O3) and a single layer of yttrium oxide (Y2O3). The coatings were designed to reduce the reflectivity of the front laser mirror from 30% to approximately 13%. The thickness of the dielectric layers was optimized for lasers emitting at 4.4 μm, with applicability in the 2.5–6 μm range. The proposed double-layer coating achieved the desired reflectivity while reducing the total coating thickness by 120 nm. By using the presented coatings it will be possible to increase the optical power of Mid-Infrared QCLs.
