Abstract
Optical vortex beams carrying orbit angular momentum have attracted significant attention recently. Perfect vortex beams, characterized by their topological charge-independent intensity profile, have important applications in enhancing communication capacity and optimizing particle manipulation. In this paper, metal-insulator-metal copper-coin type reflective metasurfaces are proposed to generate perfect composite vortex beams in X-band. We introduce the qualified equivalent circuit model based on the theory of transmission line to design the meta-atom of the structure. The experiments are performed to measure the far-field and near-field perfect composite vortex beams and evaluate their orbital angular momentum purity at different frequencies. The experimental results agree well with the theoretical predictions. This work provides new ideas and methods for generating high-quality metasurface-based perfect composite vortex beams in the microwave region, paving an ideal path for microwave communication systems, optical manipulation and radar detection.
Influence of composite material laying parameters on the load-carrying capacity of type IV hydrogen storage vessel

Published: December 2024

Abstract
The composite material laying parameters are important factors affecting the carrying capacity and quality of the type Ⅳ hydrogen storage vessel. In this article, the composite laying scheme is designed and analyzed by the finite element method. Through 100 groups of laying schemes, the influence laws of circumferential winding layers, spiral winding layers, spiral winding angle, and laying sequence are summarized. The results show that, when the number of spiral winding layers and the number of circumferential winding layers exceed 35 and 25 respectively, the bearing capacity of the hydrogen storage vessel cannot be significantly improved with the increase of the layer number. With the increase in the spiral winding angles, the maximum S11 decreases first and then increases, while the maximum S22 stabilizes first and then increases. But, for different numbers of spiral layers, the turning point of stress rise is different, and the best winding angle is between 55° and 65°. It is found that performing circumferential winding first and then spiral winding is the best winding sequence.

Abstract

Objectives
Keloids, characterized by an excessive accumulation of fibrous tissue, remain a significant dermatological challenge. This study elucidates the role of Reticulocalbin 3 (RCN3) in modulating keloid fibroblasts (KFs) in vitro.

Methods
The RCN3 expression levels in human KFs and normal dermal fibroblast cells were examined using RT-qPCR and Western blot methods. RCN3 expression was knocked down in keloid fibroblasts after cells were transfected with shRNA targeting RCN3. On the other hand, recombinant RCN3 was added to treat the cells. RT-qPCR, Western blot, flow cytometry, CCK8 assays, and wound healing assays were performed to analyze the fibrotic markers (collagen I, III, MMP2, α-SMA) and TGFβ1/Smad2/6/7 pathway, apoptosis, proliferation and migration.

Results
RCN3 was upregulated in KFs. Its knockdown reduced fibrotic marker expression (collagen I, III, MMP2, α-SMA), cell proliferation, and migration, while increasing apoptosis. Conversely, recombinant RCN3 treatment enhanced the fibrotic responses. Changes in TGFβ1/Smad2 pathway, especially in Smad2 phosphorylation and Smad7, were evident following RCN3 modulation.

Conclusions
The study reveals RCN3 as a regulator in keloid pathology, affecting fibrosis, cellular behavior through TGFβ1/Smad2/Smad7 signaling.
Zur Schreibung türkischer Familiennamen in deutschen Zeitungstexten
Authors: Zimmer Christian 
Published: December 2024

Abstract
German and Turkish differ (slightly) in terms of their grapheme inventories. This leads to variation in the spelling of many Turkish names in German: Either the Turkish letters are used (e. g. the lowercase letters ç, ğ, ı, ş) or integrated alternatives (c, g, i, and s). This article analyses how common Turkish surnames are written in German-language newspaper texts (e. g. Gündoğan vs. Gündogan). It is shown that the use of Turkish letters tends to increase, that ç is used much more frequently than the other letters, and that there are significant differences between the newspapers analysed. The change in favour of the non-integrated variants is then explained (on the basis of metalinguistic comments) with their indexical potential: the non-integrated spelling is typically interpreted as correct and respectful and serves to indicate linguistic knowledge.
Referenzketten und stilistische Variation in der Sekundarstufe
Authors: Bryant Doreen 
Published: December 2024

Abstract
If an entity is referred to multiple times in a text, a reference chain is created. This chain is considered neutral or unmarked when it is structured as follows: eine Frau – die Frau – sie – sie – sie … (‘a woman – the woman – she – she – she…’) (Thurmair 2003). Most studies on referential coherence (including those related to language acquisition) focus on animate entities in texts.
For older school pupils to handle different types of texts (e. g. reports, descriptions, explanations) adequately, the question arises as to how references are made to inanimate objects in texts and whether simple possibilities of stylistic variation are used.
In this experimental study with secondary-school pupils (Grades 5 and 8) and university students, we elicited chains of references to inanimate entities (eine Tasche – die Tasche – sie, ‘a bag – the bag – it’) and investigated the unmarked structuring of these references (indefinite NP – definite NP – personal pronoun) and the degree of precision in the introductory nominal phrase in terms of composition and/or attributes (e. g. eine Handtasche, eine gelbe Tasche, eine gelbe Handtasche, ‘a handbag, a yellow bag, a yellow handbag’). We also explored whether potential for variation was exploited through partial recurrence (e. g. eine Handtasche – die Tasche, ‘a handbag – the bag’).
Although all three groups preferred using neutral reference chains, there were clear differences in the degree of preference between the two groups of pupils, on the one hand, and the students, on the other. The groups also differed regarding their use of precision and the extent to which they varied references through partial recurrence. In addition, deviations in agreement between a pronoun and its previous mention were observed in some pupils with German as a second language who followed the semantic strategy of referring to inanimate entities using the neutral pronoun es (independent of the grammatical gender) (e. g. eine gelbe Tasche – die Tasche – *es). Another surprising finding can be seen in the student group. In an effort to express themselves diversely and eloquently, the students varied the personal and demonstrative pronouns within the reference chains without considering that demonstrative pronouns fulfil specific grammatical functions in texts (Diessel, 1999; Bosch & Umbach, 2007) and that incorrect use confuses the reader, potentially leading to misinterpretation.
As analyses of textbooks have shown that referential coherence is largely neglected in German instruction (Averintseva-Klisch, Bryant & Peschel, 2019), the findings are hardly surprising. They demonstrate once again that more attention needs to be paid to this phenomenon in teacher training and in work on texts in schools.

Relações de gênero e direitos na história da hotelaria pelotense: estudo de processos trabalhistas envolvendo mulheres entre 1940 e 1960
Authors: Duarte Renata 
Published: December 2024

O presente estudo tem como objetivo analisar documentalmente 15 processos trabalhistas da Justiça do Trabalho de Pelotas entre 1940 e a primeira metade da década de 1960, relacionados à hotelaria, que envolvem mulheres nas posições de “reclamantes” ou de “reclamadas”. A análise documental, segundo Cellard (2012), tem seu início com uma análise preliminar em cinco dimensões antes de “fornecer uma interpretação coerente, tendo em conta a temática ou o questionamento inicial” (CELLARD, 2012, p. 303). Nesse sentido, verificou-se nos processos trabalhistas a existência de salários mais baixos para as mulheres e, igualmente, que as principais profissões apresentadas possuem relação com os papéis desempenhados no ambiente familiar: camareira e cozinheira. Dessa forma, é notável a necessidade de evidenciar a atuação das mulheres enquanto força de trabalho na hotelaria.Palavras-chave: História da Hotelaria; Trabalho; Mulheres; Processos Trabalhistas; Pelotas. AbstractThis study aims to analyze, documentally, 15 labor lawsuits from the Justiça do Trabalho de Pelotas [Pelotas Labor Court] between 1940 and the first half of the 1960s. The lawsuits are related to hospitality and involve women in the positions of “defendant” or “complainants”. Documentary analysis, according to Cellard (2012), begins with a preliminary analysis in five dimensions before “providing a coherent interpretation, taking into account the theme or the initial questioning” (CELLARD, 2012, p. 303). With this in mind, it was verified in the labor processes the existence of lower salariess for women and, equally, that the main professions shown are related to the roles played in the family environment: maid and cook. Thus, the need to highlight the role of women as a work force in the hotel industry is notable.Keywords: Hotel History; Labor; Women; Labor Lawsuits; Pelotas.

Current Status of Stratigraphy of the Proterozoic Cuddapah Basin, Southern India
Authors: Saha Dilip , Patranabis-Deb Sarbani , Banerjee Amlan 
Published: December 2024

ABSTRACT
The Cuddapah basin in southern India is one of the large Proterozoic basins with rich and strategic mineral resources. As a repository of sedimentary and tectonic records spanning from the Paleoproterozoic to the Neoproterozoic, the intracratonic Cuddapah basin holds vital clues to regional crustal development, paleogeography and tectonic underpinnings of passive margin sedimentation. In this article, a brief overview of the stratigraphy of the basin is presented with emphasis on recent developments in our understanding of the physical stratigraphy controlled by multiple unconformity bound sequences suggesting multiple transgressions of the sea, the emerging geochronological constraints, and broad sedimentary environments of different formation level units. Some issues of stratigraphic classification originating from allochthonus nature of the deformed rock successions of the Nallamalai fold belt have also been examined.
Transition Zone from Precambrian Low-grade to High-grade Metamorphic Rocks and the Cauvery Suture Zone in Southern India: Traditional Concepts and Recent Researches
Authors: Chetty T.R.K. 
Published: December 2024

ABSTRACT
The contact zone (transition zone) between the low-grade tonalitic and granitic gneisses of the Archaean Dharwar craton and the Neoarchean high-grade granulite facies metamorphic rocks of the Southern Granulite Terrane (SGT) and the existence of Cauvery Suture Zone have been topics of discussion since long. Traditionally, it was strongly believed that there has been gradual transition from low- grade granitic gneisses to high- grade charnockitic rocks from north to south and the concept of transformation finds place even today in some of the latest publications. The existence of Cauvery Suture Zone/shear zone is also being questioned by a few workers. However, accumulation of large volumes of geological, geochemical, geochronological and geophysical data in the form of innumerable publications in the last 2–3 decades has transformed the traditional concepts and several new concepts and innovative ideas have emerged. Recent multidisciplinary studies clearly demarcated the tectonic contact in the place of gradual transition zone and established the existence of Cauvery suture zone and their linkage with the evolution of SGT in terms of fold-thrust tectonics related to convergent tectonic processes.
