Published: November 2024

Abstract
Objective The aim of this study was to assess the color stability of two microhybrid composite resins after immersion in different coloring solutions for 4 weeks.
Materials and Methods Sixty disc-shaped samples (2 mm in thickness and 10 mm in diameter) were prepared according to ISO standard 4049. Two composite resins were used: Filtek Z350 XT (3M ESPE) and Harvard Restore (Harvard Dental International GmbH). After initial color measurements, five samples of each resin were immersed in artificial saliva, Turkish coffee, lemonade, black tea, Coca-Cola 0%, and green tea for 4 weeks. The spectrophotometric measurements were carried out after 24 hours of immersion in the various solutions and then weekly, using a VITA Easyshade Advance 4.0 spectrophotometer (CIE L*a*b* system). Statistical analysis was carried out with SPSS 25.0 software.
Results The two composite resins tested revealed discoloration after immersion in all the drinks at a variable immersion period showing different color behaviors. The one-way analysis of variance showed a significant difference in the values of brightness (L), in chromaticity from green to red (a), in chromaticity from blue to yellow (b), and in the color (ΔE) of the two materials at different time intervals. The greatest color change in all the groups was caused by coffee followed by lemonade and black tea followed by green tea, Coca-Cola 0%, and artificial saliva.
Clinical Significance The importance of color stability of dental restorations is crucial for dental professionals and patients. Indeed, the quality of a restoration is considered from both a functional and esthetic points of view. The information obtained from this study should prove useful for clinicians to make informed decisions in selecting the best materials for their patients' esthetic restorations.
Conclusion The Harvard Restore showed a better colorimetric behavior compared with the Filtek Z350. Coffee, black tea, and green tea had the most marked effects on the discoloration of composites, especially on Filtek Z350. Coca-Cola 0% showed a similar behavior to artificial saliva.

Published: November 2024

AbstractForeign body ingestion is a commonly encountered problem clinically with management targeted at early radiological imaging to identify high-risk features that can increase the risk of perforation. We present a 23-year-old patient with no known medical or psychiatric history who presented with epigastric tenderness after ingesting multiple glass vials. The initial workup consisted of a thorough physical examination and an abdominal X-ray which revealed multiple radiopaque densities in the stomach, with some extending to the duodenum and distal colon. She underwent an emergent upper endoscopy to retrieve those glass vials given the high risk of perforation and obstruction. During the procedure, various endoscopic retrieval devices were used, however, they were unsuccessful. A novel approach was then utilized by dilating a 15-mm extraction balloon inside the lumen of the glass vials and using a snare to pull the vials out individually. Twenty-seven 6 cm × 1 cm glass vials were safely removed in a single session. The patient tolerated the procedure well and reported a complete resolution of her symptoms the next day. This case highlights the importance of obtaining prompt imaging when managing foreign body ingestion and highlights a novel endoscopic approach in safely extracting multiple glass vials that were refractory to conventional endoscopic techniques.

Published: November 2024

AbstractThe diagnostic journey in gastrointestinal lesions, particularly when presenting with atypical features, often poses formidable challenges in clinical practice. This challenge is vividly illustrated in the case of an 88-year-old man with severe acute-on-chronic gangrenous cholecystitis. Imaging studies prior to surgery unveiled an unexpected 30 × 26 mm nodular formation nestled between the pancreas and duodenum suspected for neoplasia. Endoscopic ultrasound allows obtaining an atypical benign diagnosis of a benign subepithelial lesion. This intriguing case highlights the intricate nature of differential diagnosis in such lesions, especially when they attain substantial dimensions. The nuanced imaging features and integration of advanced techniques like endoscopic ultrasound with DWI and elastography emerge as pivotal tools in achieving precise diagnosis and guiding tailored treatment strategies.

Published: November 2024

Abstract
Objectives Fabrication processes affect accuracy of restoration. This study compared marginal accuracy of ceramic veneer metal upon different metal substructure fabrication techniques, ceramic veneering methods, stages, and sites of restoration.
Material and Methods A prepared premolar metal abutment was used to fabricate 96 metal substructures from 4 techniques: cast metal with traditionally impressed tooth (CmTt), cast metal with digitally milled wax (CmDw), sintered metal with digitally impressed tooth (SmDt), and sintered metal with digitally impressed stone model (SmDm). As-cast (A) substructures were degassed (D), opaqued (O), and contoured (C) with porcelain layering (Pl) or press-on (Pp) methods and glazed (G). Marginal fit was measured at A, D, O, C, and G stages, on buccal (Bu), lingual (Li), mesial (Me), and distal (Di) sites using silicone replica.
Statistical Analysis Analysis of variance and Bonferroni test were analyzed for significant differences of marginal fit upon different factors (α = 0.05).
Results Significantly different accuracy was found upon metal substructures fabrication technique, veneering methods, stages, and sites of restoration (p < 0.05). SmDt and SmDm revealed significantly better accuracy than CmTt and CmDw (p < 0.05). Pp generated significantly better accuracy than Pl (p < 0.05). Significant increasing inaccuracy was found at D stage (p < 0.05). Me and Di sites exhibited larger inaccuracy than Bu and Li sites (p < 0.05). However, marginal inaccuracy for all groups was under clinically acceptable marginal fit.
Conclusions Increasing marginal inaccuracies upon stages of fabrication were noticed, with highly observed at the proximal site. Sintered metal provided better accuracy than cast metal, while press-on veneering generated better accuracy than the layering method. Porcelain press-on sintered metal was suggested for fabrication restoration.
Should Not Children with Ventriculoatrial Shunts Be Taking Aspirin? An Update: 0% Distal Malfunction
Authors: Udayakumaran Suhas , Kumar Shine 
Published: November 2024

Abstract
Background Ventriculoatrial (VA) shunts have the potential to preserve life in the event of failure of ventriculoperitoneal (VP) shunts. Contrary to VP shunts, they are susceptible to consequences, particularly cardiac problems. There are no established guidelines for screening patients following VA shunt placement regarding prevention, anticoagulant treatment, or risk factor screening.
Objective We aim to investigate aspirin's potential function and effectiveness in enhancing shunt survival and preventing secondary morbidity from distal thrombosis in children with VA shunts.
Materials and Methods The study's design is prospective and observational. It began in 2011 and is ongoing. Before inclusion in the study, we obtained clearance from the hospital ethics board and consent from the family. All patients with VA shunts were given a once-a-day antiplatelet dose of 5 mg/kg of aspirin from the first postoperative day. The study's primary end points include: (1) Major distal end malfunction documented on echocardiography or (2) any cardiac complications directly associated with the VA shunt.
Results Since March 2011, 13 patients have been followed up. So far, no cardiac complications have been ascribed to VA shunts in any of the patients. The current follow-up period is 28 to 170 months. Patient follow-up is continuing.
Conclusion Our observations regarding the efficacy and safety of aspirin in VA shunts are encouraging. However, sufficient time would be needed to establish its effectiveness in chronic sequelae such as pulmonary hypertension.

Published: November 2024

Abstract
Objective Medial patellar luxation (MPL) is prevalent in small dogs; however, the causes vary, and few studies have reported tibial deformities. We aimed to conduct a detailed morphological investigation of internal tibial torsion and internal foot rotation and compare the results between MPL grades to better understand the pathogenesis of MPL.
Study Design We performed a morphological study of the tibia and comparison with MPL grade, and established a new parameter, metatarsal orientation relative to the orientation of the tibial tuberosity, the proximal tibia metatarsal angle (PTMTA). The distal tibia metatarsal angle was also established, and tibial torsion angle (TTA), mechanical medial proximal tibial angle, medial distance of the tibial tuberosity/proximal tibial width, and crural rotation angle were compared among the grades of MPL.
Results The PTMTA was significantly higher in grades 3 and 4 than in the normal group. TTA, medial distance of the tibial tuberosity/proximal tibial width, and mechanical medial proximal tibial angle were significantly higher in grade 4 than in the other grades, which is consistent with previous reports. A correlation was also observed between the PTMTA and the TTA.
Conclusion The PTMTA functioned as a parameter that included elements of the distal tibia metatarsal angle, TTA, and medial distance of the tibial tuberosity/proximal tibial width, and is considered clinically useful because it can be visually ascertained during palpation. Our results may play a major role in surgical decision-making in the treatment of MPL.
Affordances and constraints of a blended learning course: experience of pre-service teachers in an African context

Published: November 2024

AbstractThis article reports our deliberate effort to redesign a traditionally taught course for pre-service teachers to suit a blended learning approach. We designed the course following the resource-activity-support-evaluation pedagogical model. Then, we investigated pre-service teachers’ perceptions of the course using a qualitative method of generation and analysis at a university in Sub-Saharan Africa. We generated the data using semi-structured interviews of pre-service teachers who gave voluntary consent and followed the blended learning course for a semester. We analysed the generated data using thematic analysis to uncover the underlying meanings across the transcribed responses. The findings showed that pre-service teachers positively perceived the blended learning course. The course provided exposure to diverse digital resources and enhanced the development of conceptual knowledge. Results indicated improved motivation, attitudes, and interest in the learning content. The course enhanced personalised learning, collaboration and flexibility through recorded videos, group projects, and electronic materials. However, our findings also revealed some constraints that prevented actualising these affordances. These include internet instability, computer proficiency gaps, online interaction issues, power supply concerns, and limited computer access. We argued that the affordances of the blended learning course overshadowed its constraints, and we explained a framework for actualising these affordances.
The interwar Romanian translation of Dracula
Authors: Martin Anca Simina 
Published: November 2024

Abstract
Barbu Cioculescu, co-translator of the 1990 Romanian rendition of Bram Stoker’s Dracula alongside
Ileana Verzea, has claimed that their rendition marked the Romanian audience’s first interaction with Stoker’s magnum
opus. In 2005 and 2009, however, scholarly articles surfaced positing the existence of an overlooked interwar
translation. Nearly a decade later, this lost translation resurfaced through the efforts of a minor publishing house, which
published it in book-length form in 2023. Serialized between 1928 and 1929, this newly rediscovered rendition, authored by
Romanian poet and prose writer Ion Gorun, stands among the earliest ten translations internationally, predating the novel’s
publication in Ireland, Stoker’s homeland, by half a decade. This study explores the rediscovery and peculiarities of Gorun’s
rendition, concurrently examining the socio-historical milieu surrounding its original release and elucidating the factors
contributing to its century-long elusiveness. Furthermore, the study shows that, despite promoting Stoker’s novel as being set in
Transylvania, Gorun’s translation tends to de-exoticize the Irish writer’s portrayal of the region, either for fear of censorship
or to circumvent confusion and disapproval among the local audience.
Narrating the sociotechnical mess
Authors: Raatikainen Pasi , Nurminen Matias 
Published: November 2024

Abstract
This article investigates how the core features of narratives and the logic of storytelling are manifested in stories told by the developers and users of an information system and how they may adversely affect their perceptions of the ongoing implementation process. Information systems and the way they operate create a negative cycle where primarily problems possess tellability. We identify a negative masterplot dominating the narratives surrounding information system projects. We examine an ongoing public sector healthcare information system project by analysing both the written narratives of frustrated health and social care professionals on a social media channel and the oral narratives told by employees of the project organisation. These stories reveal a narrative struggle and various strategies, such as positioning, used in sense-making. We suggest that a better understanding of how narratives function could help disentangle the sociotechnical issues involving information system developers and users.

Abstract
Advancements in orbital angular momentum (OAM) mode-multiplexing communication networks require tunable mode filters for selective channel demultiplexing and downloading. In this study, we propose a spatial depth-dependent mode transformation strategy for the tunable filtering of OAM modes. By integrating the spiral phase and lens phase modulations, we achieved mode conversions that varied with the transmission depth, enabling selective demultiplexing in predetermined axial planes. This approach facilitates tunable mode filtering by adjusting spatial depths. As a proof of concept, we fabricated a mode filter using two-photon polymerization lithography (TPL) technology, successfully filtering five OAM modes with mode crosstalk below −10.9 dB. Additionally, the filter was applied in a mode-multiplexing communication link, achieving tunable demultiplexing of five mode channels with bit error rates below 10−6. These results highlight the efficacy and flexibility of our strategy for OAM mode filtering and offer promising insights for the development of mode-multiplexing communication networks and channel interconnections.
Quantum effect of triple-perovskite antiferromagnets with triangular lattices, A3MB2O9 (A = Ba, Ca, and Sr; M = Co, Ni, and Mn; B = Sb, Nb)

Published: November 2024

Abstract
As a typical two-dimensional frustrated quantum magnet, the triangular-lattice antiferromagnet exhibits a series of exotic states from the complicated interplay of the lattice, spin, electron, and orbit with quantum and thermal fluctuations. From the ground state of a triangular-lattice Heisenberg antiferromagnet with coplanar 120° ordering, a series of magnetization anomalies can manifest under a magnetic field, such as the 1/3 magnetization plateau (Ms/3) and umbrella-shaped phase. This Ms/3 plateau state is recognized as an up-up-down structure stabilized by the quantum effect. By surveying theoretical research and experimental measurements on triangular-lattice antiferromagnets, this review article describes the current understanding of the magnetic properties of triple-perovskite antiferromagnets A3MB2O9(A = Ba, Ca, and Sr; M = Co, Ni, and Mn; B = Sb, Nb). Through examining both the bulk properties and spin dynamics, fascinating insights into the quantum effect on the triangular lattice are discussed.

Autoencoder and Mahalanobis distance-based monitoring indicator estimation for early clinkering detection in boiler
Authors: Sinha Aparna , Das Debanjan , Kumar Palavalasa Suneel , Singh Bugga Jaspreet 
Published: November 2024

Abstract
The performance of coal-fired boilers has a significant impact on the overall yield of thermal power plants. Among the various boiler faults, the clinkering fault diagnosis is one of the most crucial and scarcely addressed topics in literature. Existing clinkering detection methods are boiler-specific and require both healthy and faulty data for training, which is difficult to acquire. To overcome these drawbacks, a generalized method for early clinkering detection is proposed that only requires normal operation data for training. A stacked-denoising-autoencoder is trained such that the reconstruction error departs from the expected value when clinkering occurs. Mahalanobis distance of this error gives the monitoring indicator for clinkering detection, whose threshold is determined as 385.817 using kernel density estimation. The method is validated using real-time boiler data containing clinkering events, which shows that the obtained threshold clearly demarcates between healthy and clinkering conditions with 99.29% accuracy, providing early alert to operators.

Published: November 2024

Abstract
The irritation and adhesion of wound healing biomaterials to wet wounds should be addressed for achieving effective wound healing. In this study, a stable multifunctional hydrogels (BGs/HA suspension gels) were prepared using superfine powder of bioactive glasses (BGs), the biocompatible materials hyaluronic acid (HA) and carbomer940, which had good adhesion and low irritation properties for use in moist complex wounds. The average particle size of BGs/HA suspension gels was 13.11 ± 0.29 μm, and the BG content was 15.8 ± 0.2% (m m−1). The results of cell proliferation, cell migration, and immunofluorescence staining experiments showed that in the initial stage of wound healing, the ionic extract of BGs formulations promoted the proliferation and migration of L929 cells and induced the secretion of α-SMA and collagen I. In the final stage of repair, the ionic extract of the BGs formulation regulated the differentiation of fibroblast, which contributed to the reduction of pathological scar formation. In vivo experiments showed that the wound healing rate of BGs/HA suspension gels group exceeded higher than that of the conventional BGs superfine powder group. Although BGs/HA suspension gels were comparable to its commercially available counterpart (Dermlin paste) in promoting wound healing, it addressed the problem of localized irritation caused by the high pH and low adhesion of BGs products. This study confirmed the specific regulatory effect of BGs/HA suspension gels on L929 cells, which provided a reference for the clinical application of BGs in wound dressing.
Asymptotic analysis of resonance behaviors for the (2+1)-dimensional generalized fifth-order KdV equation via Hirota's bi-linear method
Authors: Bao Wang , Xu Da-Xing 
Published: November 2024

Abstract
The generalized fifth-order Korteweg–de Vries (KdV) equation, encompasses certain characteristics of the original KdV equation and is capable of describing more complex wave phenomena. The Miles resonance conditions are achieved for Y-shaped solitons by rendering the phase shift induced by the elastic interaction among N-solitons. Our investigation not only conducts a thorough analysis of the low-order resonant solutions but also presents general resonant conditions that enable the degeneration of N-solitons solutions into resonant solutions.
