Integrating optical security management with optical‐layer controller architecture for enhanced network security
Authors: Babbar Himanshi , Rani Shalli 
Published: July 2024

AbstractTo guarantee the availability, confidentiality, and integrity of data transferred over optical channels—especially in the context of fifth‐generation (5G) communication infrastructure—optical network security management is essential. This paper provides an overview of security management for optical networks, emphasizing the importance of this practice in today's communication infrastructure and the difficulties presented by ever changing cyberthreats. The architecture of optical security management is shown, with special attention to how well it integrates with current optical‐layer controllers and how it facilitates the coordination of security operations among optical networks. The study also looks at use cases for optical network security management in 5G networks, such as safe data transfer, defense against cyberattacks, maintaining privacy in 5G apps, network slicing security, and resistance to physical assaults. Such instances highlight the adaptability and significance of optical network security management in bolstering 5G networks' security, privacy, and resilience across a range of businesses and applications.

Published: July 2024

AbstractPairing is a commonly recommended practice used to build rapport and create positive therapeutic environments. However, there are limited evaluations of training procedures to teach pairing skills to direct‐care staff. The purpose of the present study was to formalize and improve the efficiency of the training process for the initial stages of pairing using video modeling with embedded voice‐over instructions plus performance feedback. Participants included three dyads of behavior technicians and children with autism. The results indicated that the training package increased the consistency of pairing implementation. These outcomes were maintained in a novel setting and for up to 4 weeks following training. We also measured relevant child behaviors such as joint attention, engagement, indices of happiness, and calm. Specific areas for future research are described.

AbstractThe present systematic review (SR) aims to evaluate manuscripts in order to help further elucidate the following question: is the micronucleus assay (MA) also a useful marker in gingiva, tongue, and palate for evaluating cytogenetic damage in vivo? A search was performed through the electronic databases PubMed/Medline, Scopus, and Web of Science, all studies published up to December 2023. The comparisons were defined as standardized mean difference (SMD), and 95% confidence intervals (CIs) were established. Full manuscripts from 34 studies were carefully selected and reviewed in this setting. Our results demonstrate that the MA may be a useful biomarker of gingival tissue damage in vivo, and this tissue could be a useful alternative to the buccal mucosa. The meta‐analysis analyzing the different sites regardless of the deleterious factor studied, the buccal mucosa (SMD = 0.69, 95% CI, − 0.49 to 1.88, p = 0.25) and gingiva (SMD = 0.31, 95% CI, − 0.11 to 0.72, p = 0.15), showed similar results and different outcome for the tongue (SMD = 1.19, 95% CI, 0.47 to 1.91, p = 0.001). In summary, our conclusion suggests that the MA can be a useful marker for detecting DNA damage in gingiva in vivo and that this tissue could be effective site for smearing.

AbstractPurposeTo systematically review existing literature regarding the ankle ligament reconstruction‐return to sport after injury (ALR‐RSI) scale and to assess its correlation with Return to sport and functional outcomes as well as feasibility, reliability and consistency.MethodsA systematic review of the literature based on the Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) was conducted using PubMed, Embase and Cochrane Library. Studies that evaluated psychological readiness to return to sport after ankle ligament reconstruction or repair for the treatment of chronic lateral ankle instability using the ALR‐RSI scale were included. The results from each study were pooled, and weighted means and overall rates were calculated.ResultsIn total, 157 patients (53.2% male, mean age: 34.2 years) from three articles were included. Overall, 85.0% of patients reported successful return to sport, but only 48.9% of patients returned to the preoperative sporting level. All studies reported a significant difference in psychological scores between patients who returned to sport and those who did not. Pooled mean patient‐reported outcome measures, reported as the American Orthopaedic Foot and Ankle Society Ankle‐Hindfoot (AOFAS, three studies) Score and Karlsson‐Peterson Score (three studies), were 82.7 (range: 29–100) and 81.7 (range: 25–100), respectively. The ALR‐RSI scale demonstrated strong correlations with the AOFAS Score and Karlsson‐Peterson Score.ConclusionPatients who returned to sport after ankle ligament reconstruction or repair exhibited higher psychological readiness compared to those who did not. The ALR‐RSI scale showed strong correlations with ankle function. Evaluation of psychological readiness using the ALR‐RSI scale may provide an additional tool in the assessment of patients who underwent ankle ligament reconstruction or repair.Level of EvidenceLevel III, systematic review.
From colonialism to international aid: Social protection in former French colonies in sub‐Saharan Africa, 1890–2020

Published: July 2024

AbstractThis article examines social protection pathways in the former French colonies in sub‐Saharan Africa. We identify five steps to understanding the patterns and dynamics of social protection in these countries that provide evidence of its exogenous construction. First, we characterize the main developments in social protection systems and policies from their inception, covering the colonial era to the present, underlining the role of colonial legacy and the global social policy framework. Second, we document the similarity of national social protection trajectories and lack of national ownership of the policy problem markedly that characterizes social protection pathways.

Published: July 2024

Aromastoffe spielen eine Schlüsselrolle in der Lebensmittelindustrie und bei der Kaufentscheidung der Verbraucher. Dabei achten Kunden verstärkt auf die Natürlichkeit der Produkte und nachhaltige Herstellungsverfahren. Um diesen Vorgaben nachzukommen, rücken höhere Pilze als Produzenten von natürlichen Aromastoffen sowie als Quelle für lebensmitteltechnologisch relevante Enzyme zur Herstellung und Qualitätsverbesserung von Lebensmitteln in den Fokus.Im Rahmen der vorliegenden Arbeit wurde der Basidiomycet Cerrena unicolor (Cun) als Sesquiterpenproduzent untersucht. Im Genom des Pilzes konnten mit Hilfe von Sequenzvergleichen 14 Sesquiterpensynthasen (STS) identifiziert werden. Zehn von ihnen wurden anschließend erfolgreich heterolog in Escherichia coli exprimiert, die Enzyme produziert und funktionell charakterisiert. Mittels tryptischem Verdau und anschließendem peptide mass fingerprinting konnten die vorhergesagten Proteinsequenzen bestätigt werden. Die Sequenzvergleiche zeigten STS‐typische konservierte Motive sowie möglicherweise für Cun spezifische Homologien. Für die Untersuchung der Metallionenabhängigkeit wurden zwei STS aus Cun gewählt, die sich sowohl in der Anzahl der Produkte, als auch den produzierten Sesquiterpenen selbst unterschieden. Setzte man andere bivalente Metallionen als Mg2+ für die Zyklisierungsreaktion ein, zeigte sich, dass die ausgewählte Multiprodukt‐Cyclase promiskuitiver als die Cyclase mit nur einem Sesquiterpen als Produkt reagierte.Weiterhin konnte gezeigt werden, dass agro‐industrielle Nebenströme für die Kultivierung von Cun verwendet werden können und diese Einfluss auf die Sesquiterpenbiosynthese hatten. Eher kohlenhydratreiche Nebenströme wie Kartoffelstärke oder Weizenkleie hatten keinen positiven Einfluss auf die Produktausbeute. Für den lipidhaltigen Rapspresskuchen konnte jedoch eine deutliche Erhöhung der Produktausbeute nachgewiesen werden. Die Hypothese, dass durch β‐Oxidation der Lipide ein Überfluss an Acetyl‐CoA die Sesquiterpenproduktion boostet, konnte mittels 13C‐markiertem Acetat als Medienzusatz experimentell bestätigt werden.

AbstractNeben dem emetischen Bacillus cereus Toxin Cereulid existieren auch zahlreiche eng strukturverwandte Isoformen. Nach chromatographischer Isolierung wurden die chemischen Strukturen der Isocereulide H–N durch Bestimmung der akkuraten m/z, NMR‐Spektroskopie, MSn Sequenzierung und posthydrolytische UPLC‐TOF‐MS Analyse aufgeklärt. Die bisher postulierte Struktur für Isocereulid A wurde revidiert, die Isocereulide H–N hinsichtlich ihrer biologischen Aktivität an HEp‐2 Zellen getestet und eine UPLC‐MS/MS Methode zur parallelen Detektion der Isocereulide A–N erarbeitet.
Comparison of analytical and numerical methods for estimating notch strains**

Published: July 2024

AbstractIn fatigue assessments, local strains and stresses can be easily evaluated using accurate finite element analysis in a case of an individual fatigue‐critical notch or structural detail. In practical design and analysis of global models, the consideration of local notch effects using suitable estimation rules in the combination with linear elastic analysis is reasonable. Various notch rules exist but the current knowledge lacks understanding how applicable different notch rules are for estimating notch strains from elastic stresses. This work studies the Neuber′s rules for sharp and mild notches, Glinka′s equivalent strain energy density method, the correction of Neuber′s rule proposed by Sonsino for mild notches, as well as the Seeger‐Beste method. The application of different estimation rules for notch strains, applied to the elastic‐perfectly plastic steel material and to Ramberg‐Osgood material model for the aluminum material, including work hardening effect, was studied in this work by comparing the estimations with the corresponding experimental data and finite element analysis results. The Neuber′s rule for mild notches and Sonsino′s averaging method gave best correlations with the experimental data and numerical (finite element analysis) results and can be thus recommended for such analyses in compatible cases studied in this work.

AbstractIn this work, the tungsten‐copper composites were fabricated by binder jet 3D printing technology. The effects of different printing layer thicknesses (50 μm to 100 μm) on the green density and green strength were investigated. Then, under the optimal layer thickness, the effects of different sintering temperatures (1300 °C to 1600 °C) on the microstructure and densification of tungsten‐40 wt.–% copper composites were studied. The experimental results showed that when the printing layer thickness was set as a lower value (50 μm), the tungsten‐40 wt.–% copper green part had the best strength and its density reached a maximum value of 60.73 %. After sintering for green parts printed with 50 μm layer thickness, the relative density, thermal conductivity and electrical conductivity of sintered parts first increased and then decreased with increasing sintering temperature. In our experiments, the tungsten‐40 wt.–% copper sample fabricated by binder jet 3D printing with a printing layer thickness of 50 μm under a sintering temperature of 1500 °C displayed the best properties, in which the relative density, thermal conductivity and electrical conductivity were 97.04 %, 228 W⋅m−1⋅K−1 and 46.5 % IACS, respectively.

Published: July 2024

AbstractAlSi10MnMg‐Legierungen werden mit verschiedenen Eisen‐, Kupfer‐ und Zinkkonzentrationen untersucht. Neben den variierten Legierungskonzentrationen werden unterschiedliche Wärmebehandlungen (F, T5 und T7) durchgeführt und anschließend auf ihre Wärmeleitfähigkeit und Wärmekapazität untersucht. Hergestellt werden die Prüfkörper mit Kokillenguss. Der Hintergrund der Untersuchungen ist die schlechte Recyclingbarkeit von Aluminiumlegierungen mit Legierungsbestandteilen von Eisen, Kupfer und Zink, da es bislang keine wirtschaftliche Methode gibt, diese Legierungsbestandteile zu entfernen. Zur Bestimmung des Einflusses der Legierungselemente Eisen, Kupfer und Zink werden Messungen der Wärmeleitfähigkeit und Wärmekapazität mit einer Hot‐Disk mit transienter Messmethode durchgeführt.

AbstractP2O5 has been widely used as an acid‐base catalyst for the O‐methylation of catechol to guaiacol due to its suitable acid strength; however, its stability, which is a significant concern for industrial applications, has not seen significant breakthroughs. Herein, we developed a facile impregnation strategy to synthesize Ce promote P2O5 supported on mesoporous silica (CeP/SBA). The CeP/SBA‐500 carbonized at 500 °C exhibited the highest catalytic activity with a catechol conversion of 71.5 %. The high activity stems from the addition of Ce, forming CePO4, which exhibits improved surface acidity compared to P2O5. Importantly, chemisorption and in situ infrared studies revealed that CePO4 shows stronger adsorption of catechol, which then rapidly converts to guaiacol. The CeP/SBA‐500 exhibits excellent stability with no activity decrease after 10 h of continuous flow reaction, attributed to the absence of a decrease in CePO4 surface acidity.

Hybrid materials (HMs) combine the high diversity of functionalities of organic compounds with properties typical for inorganic materials, such as high mechanical strength or high thermal stability. Herein, HMs combining organic pigment molecules and TiO2 as inorganic component, with covalently linked components, i.e., so‐called class II HMs, are reported. The synthesis of such HMs is intrinsically challenging, as the apolar organic pigment component and the inorganic polar TiO2 component require different conditions for their respective formation. Herein, we circumvent this issue by employing solvothermal synthesis in superheated isopropanol, which through temperature tunability of the solvent properties allows for both generating and linking both components in one‐pot. First, it is shown that an organic benzimidazole‐based pigment molecule designed for readily binding to Ti can be synthesized solvothermally. Second, new class II titanium‐based HMs are generated from Ti(OiPr)4 and pigment precursors in a solvothermal reaction. The pigment@TiO2 HMs feature significant porosity and are structurally identified as layered structures of lepidocrocite‐like TiO2 linked via pigment molecules. These layered HMs assemble into hierarchical nanoflowers, and depending on the pigment segments, different interlayer spacings in between inorganic layers are observed. Third, the pigment@TiO2 materials are shown to be usable as electrode materials in lithium‐ion batteries.
Long noncoding RNA VPS9D1‐AS1 promotes the progression of endometrial cancer via regulation of the miR‐187‐3p/S100A4 axis
Authors: Ren Wei , Ouyang Ling 
Published: July 2024

AbstractVPS9D1‐AS1 functions as an oncogene in many cancers. However, its role and potential mechanism in the progression of endometrial cancer (EC) are not fully understood. VPS9D1‐AS1 levels in EC and adjacent normal tissues were investigated using the TCGA‐UCEC cohort and 24 paired clinical samples. The roles of VPS9D1‐AS1 and miR‐187‐3p in cell cycle, proliferation, and apoptosis were evaluated by loss‐ and gain‐of‐function experiments. In addition, the effect of VPS9D1‐AS1 on tumor growth was further investigated in vivo. Rescue experiments were performed to investigate the involvement of the miR‐187‐3p/S100A4 axis in VPS9D1‐AS1 knockdown‐mediated antitumor effects. VPS9D1‐AS1 was highly expressed in EC tissues. VPS9D1‐AS1 knockdown, similar to miR‐187‐3p overexpression, significantly inhibited cell proliferation, inhibited colony formation, induced cell cycle arrest, and facilitated apoptosis of KLE cells. MiR‐187‐3p bound directly to VPS9D1‐AS1 and the 3′UTR of S100A4. Furthermore, VPS9D1‐AS1 negatively regulated miR‐187‐3p while positively regulating S100A4 expression in EC cells. MiR‐187‐3p knockdown or S100A4 overexpression partially reversed the tumor suppressive function of VPS9D1‐AS1 knockdown. The results suggest that VPS9D1‐AS1 affects EC progression by regulating the miR‐187‐3p/S100A4 axis. This may provide a promising therapeutic target to help treat EC.
Addressee Honorifics as an Interactional Resource for Socialization in Korean Adult–Child Interaction

Published: July 2024

AbstractThis study examines how addressee honorifics, recognized as an index of deference and respect, are utilized as an interactional resource for socialization in Korean adult–child interaction. This study analyzes 62 instances of adults’ use of Korean addressee honorific utterances to children collected from video recordings of five different families using multimodal discourse analytic and language socialization frameworks. The study identifies three major environments where addressee honorification serves as a tool for socializing children into socio-moral values of Korean society: a) giving compliments, b) showing gratitude, and c) issuing directives. In these interactional environments, addressee honorification is used alongside semiotic resources to evaluate children’s behaviors and draw attention to the action and content of honorific utterances. The analysis of status-incongruent and creative or performative uses of adults’ addressee honorifics further demonstrates that honorifics, which are sometimes employed for politeness and deference toward addressees, do also serve as resources for fostering social awareness, social responsiveness, and courtesy in children. This may contribute to children becoming competent members of Korean society who think, feel, and act in accordance with Korean cultural norms and expectations.
Solidarity Through Negotiated Interactional Identities in Korean
Authors: Park Mee-Jeong 
Published: July 2024

AbstractThis paper shows how Korean speakers use different strategies to increase solidarity among newly acquainted interlocutors in performing common tasks by co-constructing through the negotiation process of their interactional identities and adjusting themselves to the right level of intimacy and/or politeness within the given interaction. According to (Swann, Journal of Personality and Social Psychology 53:1038–1051, 1987), 2008), “identity negotiation” refers to the processes where interactants try to find a balance between their interactional and identity-related goals, keeping a conflict-free relation between their interpersonal and intrapersonal interactions. The ways in which Korean speakers negotiate their situational and interactional identity will be illustrated using excerpts taken from TV talk shows, reality shows, or dramas where different participants achieve what is considered an adequate level of intimacy with their conversational partners within the given tasks as the show participants. In interactions where Korean speakers meet for the first time, it is very common to see how they exchange personal information. Among them, interlocutors’ age is very often exchanged at the very early stage of their encounter. In many reality shows and talk shows on Korean TV, participants often start their first-time encounter by asking about their age and work-related backgrounds. Interlocutors achieve an increased level of intimacy by assigning newinteractional identities to themselves, that of (a) friends (=same age), (b) siblings (=different age), or (c) senior/junior (work-related). Oftentimes, this process is streamlined by adjusting their speech styleand/or address terms that match their newly constructed identities in order to successfully perform their common tasks.
