Analysis of a nonlinear dynamic absorption system
Authors: Nešić Nikola , Simonović Julijana , Nestorović Tamara 
Published: September 2024

AbstractPassive dynamic absorbers, also known as mass dampers, are typically investigated for their use in vibration suppression of buildings and structures. The proposed model consists of two rigid bodies, where the main body rests on a viscoelastic foundation. Additional attached mass represents a nonlinear energy sink. The dynamical interaction and behavior of a two‐degree‐of‐freedom mechanical system are described with a system of two coupled differential equations of the second order. The first equation contains the damping term. The second equation is nonlinear. The nonlinear differential equation system is solved using an incremental harmonic balance method. The influence of the resting foundation's viscoelastic properties on the main body's dynamics is analyzed. Additionally, the variations of other system parameters, especially the mass damper features, on amplitude‐frequency response curves are analyzed and discussed.
Effect of printing parameters on the mechanical properties of 3D printed short glass fiber/acrylonitrile butadiene styrene composites
Authors: Rahmati Moein , Zolfaghari Abbas 
Published: September 2024

AbstractThree‐dimensional (3D) printing, or additive manufacturing (AM), is rapidly advancing, allowing for the creation of objects from a digital model through the successive addition of materials. Among the AM techniques, fused deposition modeling (FDM) emerges as one of the most promising and extensively utilized methods. However, the inherent mechanical shortcomings of the deposition of pure thermoplastic materials necessitate the improvement of mechanical properties. One viable approach involves integrating reinforcing fibers into the thermoplastic matrix to create polymer composites suitable for structural applications. In this study, the mechanical properties of acrylonitrile butadiene styrene (ABS) reinforced with short glass fibers (SGFs) printed by FDM were investigated. The aim was to explore the impact of process parameters, including nozzle temperature, number of shells, and print speed, on the tensile properties and interlaminar shear strength (ILSS). Composite filament with 10% weight fraction (10 wt%) of glass fiber fabricated. Also, the mechanical properties of the composite and pure polymer were investigated. The length of the fibers was measured after the extrusion and printing process, revealing that they had been damaged. The shells exerted the most significant influence on test outcomes.

Published: September 2024

AbstractBackgroundBronchopulmonary dysplasia (BPD) is a severe chronic lung disease primarily affecting premature infants, often resulting from prolonged mechanical ventilation and oxygen therapy. Oxidative stress plays a critical role in the pathogenesis of BPD, contributing to lung injury, inflammation, and impaired lung development. Despite extensive research, there is a need to systematically map out the research trends and hotspots in this field to inform future studies and therapeutic strategies.MethodsThis study utilized bibliometric and visualized analysis to explore global research trends and hotspots on oxidative stress and BPD from 2004 to 2024. A comprehensive literature search was conducted in the Web of Science Core Collection, focusing on publications related to oxidative stress and BPD. Tools such as VOSviewer, Citespace, and the R package Bibliometrix were employed to analyze Coauthorship, co‐citation, and keyword co‐occurrence networks, as well as to identify emerging research fronts and influential studies.ResultsThe analysis identified 597 relevant publications, showing a steady increase in research output over the 20‐year period, with a significant surge in the last decade. The United States led in research contributions, followed by China and Germany, with notable collaborations among these countries. Coauthorship analysis highlighted key research institutions, such as Harvard University and the University of California, as central nodes in the research network. Thematic clustering revealed five major research areas: antioxidant mechanisms, inflammation, molecular pathways, lung development, and therapeutic interventions. The keyword co‐occurrence analysis showed a shift in research focus over time. Early studies concentrated on basic pathophysiological mechanisms, while recent research has increasingly focused on advanced molecular techniques, such as gene expression and targeted therapies. Notably, the study identified emerging research hotspots, including the role of extracellular vesicles and cellular senescence in BPD, as well as the potential therapeutic applications of antioxidants like superoxide dismutase mimetics.ConclusionThis bibliometric study provides a comprehensive overview of the research landscape on oxidative stress and BPD, identifying key trends, influential authors, and emerging research topics. The findings underscore the importance of continued research in this field, particularly in translating basic scientific insights into clinical applications to improve outcomes for infants affected by BPD. The study also highlights potential areas for future investigation, including the development of novel therapeutic strategies targeting oxidative stress in BPD.

AbstractBackground and PurposeWarm‐up (WU) is a commonly practiced technique aimed at preparing athletes for physical activity. Although coaches and athletes consider WU essential, there is still an ongoing debate about its effectiveness. This might be due to the fact that WU procedures often rely on experiences rather than scientific research. During WU, athletes may pursue intermediate goals such as ensuring proper ranges of motion in joints, which seem crucial particularly for runners' ankle joints. Hence, the aim of this study was to evaluate influence of whole‐body vibration (WBV), drop jump (DJ), and a combination of both (WBV + DJ) in terms of ankle dorsiflexion and running parameters among recreational runners.MethodsSixteen runners performed as a WU: five sets of 30 s calf raises without WBV (CTRL), five sets of 30 s calf raises during WBV, five sets of six DJ, five sets of 30 s calf raises during WBV followed by 6 DJ. Range of motion (ROM) of the ankle joint was measured in a prone position using an inclinometer for the soleus and gastrocnemius muscles, separately. Measurements were conducted before and after WU, and after a 3000 m run.ResultsThere was no interaction for time and WU for left (p = 0.926) and right (p = 0.738) soleus muscle as well as for left (p = 0.748) and right (p = 0.197) gastrocnemius muscles. No difference (p = 0.914) for the running time was found.DiscussionWBV, drop jumps, or a combination of both did not affect ankle dorsiflexion and running time.
de Sitter State in Heterotic String Theory

Published: September 2024

AbstractRecent no‐go theorems have ruled out four‐dimensional classical de Sitter vacua in heterotic string theory. On the other hand, the absence of a well‐defined Wilsonian effective action and other related phenomena also appear to rule out such time‐dependent vacua with de Sitter isometries, even in the presence of quantum corrections. In this note, the authors argued that a four‐dimensional de Sitter space can still exist in heterotic string theory as a Glauber–Sudarshan state, i.e., as an excited state, over a supersymmetric Minkowski background, albeit within a finite temporal domain. Borel resummation and resurgence play a crucial role in constructing such a state in the Hilbert space of heterotic theory governed entirely by the IR degrees of freedom.

AbstractBACKGROUNDRice leafroller is a serious threat to the production of rice. Monitoring the damage caused by rice leafroller is essential for effective pest management. Owing to limitations in collecting decent quality images and high‐performing identification methods to recognize the damage, studies recommending fast and accurate identification of rice leafroller damage are rare. In this study, we employed an ultra‐lightweight unmanned aerial vehicle (UAV) to eliminate the influence of the downwash flow field and obtain very high‐resolution images of the damaged areas of the rice leafroller. We used deep learning technology and the segmentation model, Attention U‐Net, to recognize the damaged area by the rice leafroller. Further, a method is presented to count the damaged patches from the segmented area.RESULTSThe result shows that Attention U‐Net achieves high performance, with an F1 score of 0.908. Further analysis indicates that the deep learning model performs better than the traditional image classification method, Random Forest (RF). The traditional method of RF causes a lot of false alarms around the edge of leaves, and is sensitive to the changes in brightness. Validation based on the ground survey indicates that the UAV and deep learning‐based method achieve a reasonable accuracy in identifying damage patches, with a coefficient of determination of 0.879. The spatial distribution of the damage is uneven, and the UAV‐based image collecting method provides a dense and accurate method to recognize the damaged area.CONCLUSIONOverall, this study presents a vision to monitor the damage caused by the rice leafroller with ultra‐light UAV efficiently. It would also contribute to effectively controlling and managing the hazardous rice leafroller. © 2024 Society of Chemical Industry.

AbstractTuberculosis (TB) may cause significant long‐term cardiorespiratory complications, of which pulmonary vascular disease is most under‐recognized. TB is rarely listed as a cause of pulmonary hypertension (PH) in most PH guidelines, yet PH may develop at various stages in the time course of TB, from active infection through to the post‐TB period. Predisposing risk factors for the development of PH are likely multifactorial, involving active TB disease and post‐TB lung disease (PTLD), host‐related and environment‐related factors. Moreover, post‐TB PH should likely be classified in Group 3 PH, with the pathogenesis similarly complex and multifactorial as other Group 3 PH causes. Identifying risk factors that predispose to post‐TB PH may aid in developing risk stratification criteria for early identification and referral for confirmatory diagnostic tests. Given that universal screening for PH in TB survivors may be impractical and unfeasible, a targeted screening approach for high‐risk individuals would be sensible. In this scoping review of post‐TB PH, resulting from the proceedings of the 2nd International Post‐Tuberculosis Symposium, we aim to describe the epidemiology, risk factors, and pathophysiology of post‐TB PH. We emphasize diagnosing PH with an alternative set of diagnostic guidelines in resource‐constrained settings where right heart catheterization may not be feasible. Research to describe the burden and distribution of post‐TB PH should be prioritized as there is a current gap in knowledge regarding the prevalence and incidence of post‐TB PH among persons with TB.

AbstractHigh‐quality solid electrolyte interphase (SEI) layers can effectively suppress the growth of Li dendrites and improve the cycling stability of lithium metal batteries. Herein, 1‐(6‐bromohexanoyl)‐3‐butylurea is used to construct an organic/inorganic hybrid (designated as LiBr‐HBU) SEI layer that features a uniform and compact structure. The LiBr‐HBU SEI layer exhibits superior electrolyte wettability and air stability as well as strong attachment to Li foils. The LiBr‐HBU SEI layer achieves a Li+ conductivity of 2.75 × 10−4 S cm−1, which is ≈50‐fold higher than the value measured for a native SEI layer. A Li//Li symmetric cell containing the LiBr‐HBU SEI layer exhibits markedly improved cyclability when compared with the cell containing a native SEI layer, especially at a high current density (e.g., cycling life up to 1333 h at 15 mA cm−2). The LiBr‐HBU SEI layer also improves the performance of lithium−sulfur cells, particularly the rate capability (548 mAh g−1 at 10 C) and cycling stability (513 mAh g−1 at 0.5 C after 500 cycles). The methodology described can be extended to the commercial processing of Li metal anodes as the artificial SEI layer also protects Li metal against corrosion.

AbstractNitric oxide (NO), a key element in the regulation of essential biological mechanisms, presents huge potential as therapeutic agent in the treatment and prevention of chronic diseases. Metal‐organic frameworks (MOFs) with open metal sites are promising carriers for NO therapies but delivering it over an extended period in biological media remains a great challenge due to i) a fast degradation of the material in body fluids and/or ii) a rapid replacement of NO by water molecules onto the Lewis acid sites. Here, a new ultra‐narrow pores Fe bisphosphonate MOF, denoted MIP‐210(Fe) or Fe(H2O)(Hmbpa) (H4mbpa = p‐xylenediphosphonic acid) is described that adsorbs NO due to an unprecedented sorption mechanism: coordination of NO through the Fe(III) sites is unusually preferred, replacing bound water, and creating a stable interaction with the free H2O and P‐OH groups delimiting the ultra‐narrow pores. This, associated with the high chemical stability of the MOF in body fluids, enables an unprecedented slow replacement of NO by water molecules in biological media, achieving an extraordinarily extended NO delivery time over at least 70 h, exceeding by far the NO kinetics release reported with others porous materials, paving the way for the development of safe and successful gas therapies.
Macroalgae from the early Cambrian Chengjiang biota
Authors: Li Gaorong , Wei Fan , Guo Jin , Cong Peiyun 
Published: September 2024

AbstractThe Chengjiang biota, a Burgess Shale‐type Lagerstätte in eastern Yunnan, South China (Cambrian Series 2, Stage 3), provides valuable information regarding the origin and early evolution of metazoans, and complex marine ecosystems. Although the major animal phyla in the Chengjiang biota have been extensively studied, macroalgae have received comparatively little attention. Here, we establish new taxa Yunnanospirellus typica and Y. elegans, describe five genera and six species (Tawuia sp., Morania fragmenta, Liulingjitaenia alloplecta, Longfengshania stipitata, Lo. spheria and Paralongfengshania sicyoides) not previously reported in the Chengjiang biota, and elucidate the pith structure of Enteromophites intestinalis. With 13 genera and 17 species now recorded, macroalgae rank fourth in species‐level biodiversity in the Chengjiang biota (behind Euarthropoda, Porifera and Priapulida). Macroalgae account for 71.57% of total abundance, far more than all other animal phyla in the Chengjiang biota. Fuxianospira is the most dominant genus, accounting for 52.01% of all macroalgae specimens. Unattached (floating, planktonic or drifting) forms dominate (eight attached; nine unattached species). The high diversity of attached macroalgae indicates that the macroalgal communities adapted to the Proterozoic firm substrate (probably covered by microbial mats) persisted from the Ediacaran to the early Cambrian, providing compelling evidence for the existence of firm substrate during this time. Meanwhile, the blooming of unattached macroalgae in the Chengjiang biota suggests that other niches were also rich in macroalgae. Unattached macroalgae might have provided oxygen and energy to metazoans, eventually leading to ecological expansion in the upper and middle water column of the early Cambrian seas.

AbstractThe aim of this research is to investigate the influence of food‐grade organic acids incorporation in buckwheat starch films obtained by casting. Buckwheat starch is extracted via the alkaline methodology, and the impact of different acids and concentrations on film properties is evaluated. The films are submitted to the following characterizations: mechanical and moisture resistance properties, water vapor permeability (WVP), thermogravimetry (TG), field emission gun scanning electron microscopy (FEG‐SEM), and ATR‐FTIR (Attenuated Total Reflectance‐Fourier Transform Infrared) spectroscopy. Incorporating organic acids show film moisture reduction, WVP, and increased thermal stability. Among the organic acids tested, the films with tartaric and citric acids provide the most positive impact on the films’ mechanical and water resistance. In contrast, malic acid is demonstrated to have a less efficient crosslinking capacity.

Published: September 2024

ABSTRACTGossypol, a natural polyphenolic compound, possesses antivirus activity and induces cell death of different types of tumors. However, the efficacy of gossypol on lung carcinoma metastases and epithelial to mesenchymal transition remains unknown. The aim of the present work was to determine the cellular and molecular mechanism of the anti‐cancer and anti‐metastatic efficacies of gossypol on human lung carcinoma cells. Gossypol showed a marked suppression of the viability, motility, and invasion in H1299 and A549 cells. Zymography assay showed that gossypol was sufficient to suppress the activities of urokinase‐type plasminogen activator and matrix metalloproteinase‐2. Gossypol reversed TGF‐β‐induced epithelial to mesenchymal transition. Gossypol reduced vimentin, p‐FAK, p‐Src and p‐paxillin. In vivo studies of gossypol were performed using subcutaneous inoculation and tail vein injection of A549 into immunodeficient BALB/c nude mice and severe combined immunodeficient mice.
Extending Isabelle/HOL’s Code Generator with Support for the Go Programming Language
Authors: Stübinger Terru , Hupel Lars 
Published: September 2024

AbstractThe Isabelle proof assistant includes a small functional language, which allows users to write and reason about programs. So far, these programs could be extracted into a number of functional languages: Standard ML, OCaml, Scala, and Haskell. This work adds support for Go as a fifth target language for the Code Generator. Unlike the previous targets, Go is not a functional language and encourages code in an imperative style, thus many of the features of Isabelle’s language (particularly data types, pattern matching, and type classes) have to be emulated using imperative language constructs in Go. The developed Code Generation is provided as an add-on library that can be simply imported into existing theories.
