An acute bacterial infection called avian spirochetosis is spread by ticks to a variety of birds. Clinical symptoms can vary greatly and are frequently non-specific. To diagnose a condition, the infectious spirochete must be detected. Here, we structure an epidemic model for the transmission of avian spirochetosis to visualize the interaction between tick and bird populations. The recommended dynamics of avian spirochetosis is illustrated with the help of fractional framework. We inspected the steady-states of the system of the avian spirochetosis for the stability analysis. The next-generation technique is used to evaluate the model’s reproduction parameter (Formula presented.) The infection-free and endemic steady-state of avian spirochetosis were shown to be locally asymptotically stable under the specified conditions. Through mathematical skills, the positivity of solutions is determined. Additionally, evidence supporting the existence and uniqueness of the avian spirochetosis framework solution has been shown. We conduct modified simulations of the suggested avian spirochetosis system with different input factors to study the complex phenomena of avian spirochetosis under the effect of numerous input parameters. Our outcomes illustrate the significance and plausibility of fractional parameter, and they also suggest that this input parameter may adequately account for these kinds of observations. © 2023 Informa UK Limited, trading as Taylor & Francis Group.

In this study, gallium oxide (Ga2O3) nanorods were deposited onto an indium tin oxide (ITO) glass substrate to develop a real-time living cell viability sensor. Ga2O3 nanorods had characteristics of cell population sensing based on cellular metabolism to detect cell viability. The ph sensing characteristics of Ga2O3-based extended-gate field-effect transistors (EGFETs) with and without the annealing process were measured from ph 1–11. Three different sensor heads, ITO/glass, GaOOH/ITO/glass, and Ga2O3/ITO/glass, were produced as EGFETs and immersed into a ph standard buffer and high-glucose dulbecco's modified Eagle's medium (dMEM) to investigate hydrogen ion sensing. Results showed that the Ga2O3/ITO/glass probe had the best hydrogen ion sensing sensitivity and stability in different sample buffers. In contrast, GaOOH/ITO/glass had instability and lower sensitivity due to interference with other components in the medium. The drift characteristic of sensors was analyzed to detect long-term stability. The Ga2O3/ITO/glass probe showed lower drift properties, which can potentially monitor the dMEM situation in real-time for a long-term period. during in vitro detection, the Ga2O3/ITO/glass probe revealed a 70 μA/cells change in IdS-VdS analysis and a 10 μV/cells change in IdS-VGS analysis, which was superior linearly dependent within 10,000 cells. The biocompatibility of the Ga2O3/ITO/glass probe was also detected by 3-(4,5-dimethylthiazol-2-yl)− 2,5-diphenyltetrazolium bromide assay and showed no cytotoxicity. Overall, the Ga2O3/ITO/glass EGFET sensor has potential applications as a living cell viability device in microenvironmental studies in the future. © 2022 Elsevier B.V.

作者： Rao, Neralla Vijayakameswara Mathew, Jacob Le, Trong-Nghia Lee, Cheng-Kang Huang, Ru Department of Chemical Engineering National Taiwan University of Science and Technology Taipei Taiwan School of Pharmacy College of Pharmacy Taipei Medical University Taipei Taiwan Ph.D. Program in Drug Discovery and Development Industry College of Pharmacy Taipei Medical University Taipei Taiwan National Taiwan University of Science and Technology Taiwan

Norborene-derived block polymers with selenol-containing components and norbornene-polyethylene (PNEG) components are proposed for the development of diselenide-crosslinked polymer nanoparticles (dC PNPs), in situ, which are responsive to the abnormal ROS levels in the tumoral region, as anticancer drug carriers. These nanoparticles can be designed to release anticancer drugs selectively in the tumor microenvironment, minimizing systemic toxicity and enhancing therapeutic efficacy. The diselenide bonds in the polymer degrade in response to high levels of reactive oxygen species (ROS), which are characteristic of cancerous tissues, thereby releasing the drug at the target site. In micelles, doxorubicin (dOX) is effectively encapsulated in the hydrophobic core and the shell is strengthened by diselenide crosslinks (dOX- dC PNPs). A dLS particle stability study demonstrated that structural integrity was maintained for three days under physiological conditions. However, the hydrophobic diselenide bond successfully fragmented into hydrophilic selenic acid derivatives under ROS conditions, leading to the release of the payload from the drug-containing matrix. Validation of the drug release showed that 52% of the payload was released at a H2O2 concentration of 10 µM, ensuring the reactive matrix reaction;s optimal accuracy. A toxicity study on a normal cell line (L929) confirmed the polymer's biocompatibility, while the encapsulated model exhibited significant toxicity to a cancer cell line (Hela). In contrast to free dOX, dOX-loaded polymer nanoparticles (PNPs) displayed a lower toxicity threshold, attributed to their capacity for gradual drug release over time. Furthermore, a comparison of cellular uptake reveals that while free dOX provides immediate drug availability, dOX loaded PNPs offer a more controlled and sustained release mechanism. In cancer therapy, this characteristic enhances therapeutic efficacy while minimizing side effects associated with high concentrati

data centres and high-performance computing systems rely on numerous network switches for data management and often integrate renewable energy sources (such as solar power) with storage batteries to ensure a stable power supply. In this paper, we introduce a novel regenerative snubber for boost converters with the aim of reducing the component count and footprint compared to conventional designs. Traditional boost converters suffer from high switching losses due to hard switching techniques. Although soft-switching methods can reduce these losses, they often involve costly and bulky components. In the proposed design, a minimal additional inductor is employed to achieve both turn-on and turn-off soft switching, enhancing efficiency without increasing size or complexity. The paper includes a detailed description of the circuit’s operation and timing, prototype test results, and a comparative analysis to demonstrate the advantages of this new approach over existing solutions in the literature.

Marine pollution by various debris is rising in the context of increasing urbanization, industrialization and worldwide trade. Here, we review marine macro-litter with focus on sources, abundance, distribution, and impact on aquatic wildlife, human health, and the economy. We observe that about 75–80% of marine litter originates from land-based sources, including poorly managed landfills and improper disposal. Macro-litter ingestion by marine life is of growing concern, in particular concerning the presence of plastics and associated pollutants, e.g., bisphenol A and phthalates, in fishes. These pollutants are accumulated and transferred to human via seafood. Marine plastic pollution induces a substantial rise of economic costs due to the decline of ecosystem services. Mitigation of marine plastic pollution should be done by following the ten Rs principles of refuse, rethink, reduce, re-use, repair, refurbish, remanufacture, repurpose, recycle, and recover. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2024.

Over the years, the grinding wheels industry has played a crucial role in mechanical engineering. Grinding wheel specification is composed of various factors such as abrasive type, wheel grade, bond type, and more, which are derived from customer workpiece operation information. Traditionally, the determination process of grinding wheel specifications is complicated. Experienced engineers need to check out the limitation and consider the interaction of each factor. When the new specification order comes, engineers have to spend a lot of time on historical data search and discussion. Recently, the application of artificial intelligence attracts more and more attention in the manufacturing industry. Through collecting historical data, the model has the ability to extract the domain knowledge, predict the specification that does not exist, and reduce the decision time. However, when training the model, this grinding wheel specification faced multiple imbalanced targets and multi-task issues. In the past, research efforts primarily focused on studying single-task learning (STL) algorithms. Seldom of them has a systematic way to discuss the model determination of multiple targets and correlation influence, especially on the tabular-type dataset. In this study, we proposed a multiple resampling chain multi-task learning framework to address the issue of data science. To tackle the multi-task imbalance resampling problem, we also proposed a resampling strategy called Multiple Resampling Chain. Moreover, we conducted a sensitivity analysis to examine the correlation effect on model improvement. Finally, we proposed a cyber-recommendation system that integrates the training model and interface to provide a more intuitive way of specification prediction. This system not only can help engineers to improve the time spent on making decisions, but also make the whole manufacturing process to be more intelligent. © 2024 Elsevier Ltd

Fine particulate matter (PM2.5) emitted from marine transportation, bulk materials handling at the docks, and dust dispersion has garnered increased attention, particularly in the interface between port and urban areas. This study explored the inter-transport of PM2.5 between Kaohsiung Harbor and neighboring Metro Kaohsiung. Chemical analyses of PM2.5 samples from four sites include water-soluble ions, metallic elements, carbons, anhydrosugars, and organic acids to establish PM2.5's chemical fingerprints. The CALPUFF air dispersion model is employed to simulate the spatiotemporal distribution of PM2.5 in Kaohsiung Harbor and adjacent urban areas. A clear seasonal and diurnal variation of PM2.5 concentrations and chemical composition was observed in both harbor and urban areas. The high correlation of nighttime PM2.5 levels between the port and urban areas suggests inter-transport phenomena. Sea salt spray, ship emissions, secondary aerosols, and heavy fuel-oil boilers exhibit higher levels in the port area than in the urban area. In Metro Kaohsiung, mobile sources, fugitive dust, and waste incinerators emerge as major PM2.5 contributors. Furthermore, sea breeze significantly influences PM2.5 dispersion from Kaohsiung Harbor to Metro Kaohsiung, particularly in the afternoon. The average contribution of PM2.5 from ships' main engines in Kaohsiung Harbor ranges from 2.9% to 5.3%, while auxiliary engines contribute 3.8%–8.3% of PM2.5 in Metro Kaohsiung. © 2024 Elsevier Ltd
