Published: December 2024

At present, the traditional container terminal handling system has many problems, such as high energy consumption, high cost and low efficiency. Therefore, this study drew on the characteristics of "hump" transportation to design a sliding track type, three-dimensional wharf handling system. Meanwhile, considering the design problem of safety dip angle during the loading and unloading operation of the sliding rail terminal, this study constructed the calculation model of the optimal dip angle of the sliding rail operation. This provides a decision support for the improvement of the port handling system. Based on the aforementioned questions, this study first quantified the effects of temperature, humidity and container material. The correction factor for the friction coefficient was obtained. Secondly, combined with the classical mechanics theory, this study developed an optimal calculation model for the inclination of the sliding rail operation under the comprehensive effect of multiple factors. Finally, this study verified the rationality and safety of the optimal dip angle for a specific numerical case of a port. The results show that the safe inclination angle calculated in this case is 21.9°, which meets the requirements of safe operation. The applicability of the above research is verified.

AbstractObjectivesTo examine bulk‐billing rates and out‐of‐pocket costs for non‐bulk‐billed general practitioner services in Australia at the Statistical Area 3 (SA3) level; to assess differences by area‐level socio‐economic disadvantage and remoteness.Study designRetrospective analysis of administrative data (Medicare claims data).Setting, participantsAll Medicare claims for non‐referred general practitioner services in Australia during the 2022 calendar year, as recorded in the Person Level Integrated Data Asset (PLIDA).Main outcome measuresMean proportions of general practitioner services that were bulk‐billed and mean patient out‐of‐pocket costs for non‐bulk‐billed general practitioner visits by SA3 region, adjusted for area‐level age and sex, both overall and by area‐level socio‐economic disadvantage (Index of Relative Socioeconomic Disadvantage quintile) and remoteness (simplified Modified Monash Model category).ResultsDuring 2022, 82% (95% confidence interval [CI], 80–83%) of general practitioner services in Australia were bulk‐billed; the mean out‐of‐pocket cost for non‐bulk‐billed visits was $43 (95% CI, $42–44). By SA3, mean bulk‐billing rates ranged between 46% and 99%, mean out‐of‐pocket costs for non‐bulk‐billed general practitioner visit between $16 and $99. Bulk‐billing rates were higher in regions in the most socio‐economically disadvantaged quintile (86%; 95% CI, 84–88%) than those in the least disadvantaged quintile (73%; 95% CI, 70–76%); the mean rate was not significantly different for remote (86%; 95% CI, 79–92%) and metropolitan areas (81%; 95% CI, 79–83%). Out‐of‐pocket costs for non‐bulk‐billed general practitioner services were higher in remote ($56; 95% CI, $46–66) than in metropolitan areas ($43; 95% CI, $42–44), and lower in areas in the most socio‐economically disadvantaged quintile ($42; 95% CI, $40–45) than in those in the least disadvantaged quintile ($47; 95% CI, $45–49).ConclusionAlthough most general practitioner services are bulk‐billed, out‐of‐pocket costs for non‐bulk‐billed services are relatively high, particularly for people in remote and socio‐economically disadvantaged areas of Australia.

Published: December 2024

In the current economic conditions, an active search is conducted for cost-effective and well-balanced feeds and feed mixtures for fish farming. The development of functional feeds using biomass of wild algae is becoming a central focus in the fish feed production. Although these supplements offer a promising path to sustainable and environmentally friendly fish feeding, their impact on the ecosystem requires detailed research. The aim of the study was to determine the acute response of Daphnia magna to the influence of new feed products derived from the wild algae of the Baltic Sea, phycocyanin on its own, and their binary mixture. The study was conducted using the standard aquatic toxicology method. To establish the 48-hour LC50, the probit analysis method was used. The results showed that D. magna is more sensitive to the effects of phycocyanin, with the following order of toxicity: phycocyanin > the mixture (1:1) > the biomass of Cladophora sp. The median lethal concentrations at 48 h were 100 mg/l, 920 mg/l, and 1720 mg/l, respectively. The obtained data allows to refer the tested compounds to low-hazard substances according to the Globally Harmonized System (GHS). The observed effects were compared with the effects of the mixture noticed in the toxic units (TU) model. In 48 hours, the mixture of the dry biomass of Cladophora sp. and phycocyanin at a ratio of 1:1 exhibited synergism. The obtained results will allow choosing the optimal ratio of the raw materials used in fish feeds without inflicting harm to the aquatic ecosystem and loss of their nutritional value.

Published: December 2024

The scarcity of clean water in rural Nigerian communities leads to dependence on streams and rivers which are often polluted by domestic and industrial activities distorting the quality of water. Freshwater ecosystems, which are important for global biodiversity, are constantly burdened with threats from environmental changes as well as human misuse. This study was aimed at investigating the spatial and temporal variations of physico-chemical parameters and the water quality index (WQI) of the Okhuaihe River in Ikpe, Edo state, Nigeria, used for different domestic activities. The study assessed parameters like air and water temperature, pH, electrical conductivity, flow rate, total dissolved solids, phosphate, chloride, iron, zinc, and manganese at four stations over a six-month period. Samples such as air and water temperature and pH were collected and measured in situ, while others were collected using polyethylene bottles and a 250 ml amber bottle for biochemical oxygen demand (BOD5). Results indicated that while some physico-chemical parameters like the width, the flow rate, and phosphate showed considerable differences, most did not differ significantly. Temporally, there were significant seasonal variations in air temperature, electrical conductivity, total dissolved solids, chloride, iron, zinc, and manganese. The WQI calculations showed that the water quality at all stations was within safe limits for human consumption and supported aquatic life. Despite some fluctuations due to seasonal changes and anthropogenic activities, the overall quality remained suitable for domestic use. This underscores the importance of constant monitoring and management of water resources to allay pollution and ensure sustainable water supply in rural communities.

The theory of full non-rigid molecular groups (f.NRG) proves useful in exploring the internal dynamics of these molecules. In this study, we determined the group order of Cyclopentane and identified its conjugacy classes. Using computational methods, we calculated the group order, its character table, conjugacy classes and the point group of Cyclopentane was analyzed. Our results showed that the point groups were found to be isomorphic to the Wreath Product 〖 Z〗_5 wrZ_2, where Z_n represents a cyclic group of size n, with order 160 and 16 conjugacy classes. All calculations were performed using GAP 4.11.1.

Authors: Molins Caroline , Martinez Martinez Carmen J 
Published: December 2024

Objective Multisource feedback or 360-degree assessments are known to be a reliable and feasible evaluation tool that can have profound effects on residents. Direct observation of resident’s patient encounters is a useful educational instrument that provides information about a resident’s strengths and weaknesses but can be costly and difficult to implement on a regular basis. In order to facilitate the 360-degree assessments and enhance resident education, direct observation teaching shifts (DOTS) were created. DOTS were defined as scheduled shifts in which paired faculty/residents were assigned a chief complaint based patient encounter and the 360-degree assessment was used as the evaluation tool. The purpose of this innovation was to assess the resident’s perceptions and number of timely completed 360 evaluations after the introduction of DOTS. Methods Using the American Board of Emergency Medicine Model of Practice of 2016, signs, symptoms and presentations that were identified as “critical” were matched to reference textbook chapters for reading and studying purposes. Each 4 week block was assigned two distinct topics. Over a 12-week period, residents that were scheduled to the EM rotation were assigned DOTS paired with a designated faculty member, who received faculty development on DOTS and feedback. All residents had the opportunity to have at least 1 DOTS. At the completion of the 12-week period, residents and faculty were surveyed using Microsoft Forms and data was extracted and analyzed using Microsoft Excel. Results After completing the 12-week period, the number of 360 evaluations more than tripled per week. Most of the residents that were scheduled a DOTS completed a 360 evaluation (67%) and felt that they received individualized learning (83%) from the attending. In conclusion, the majority (75%) said that they would like to continue to be scheduled DOTS. All the attendings involved in DOTS believe that we should continue completing the DOTS and involve more attendings. Conclusion With the implementation of DOTS, there was a three-fold increase in 360-degree assessments completed, and the resident’s perceived that it was educationally beneficial to them.

Distributed adaptive state estimation and tracking by using active‐passive sensor networks

Published: January 2020

SummaryHeterogeneous sensor networks (HSN) find a wide range of applications in the field of military and civilian environments, where sensor nodes are utilized to estimate the position of a target with both dynamics and control input being unknown for the purposes of tracking. In the HSN, nodes are considered active depending upon their ability to sense the target output while the others are taken passive. Accurate estimation requires local information exchange among the spatially located sensor nodes, so that the active nodes as well as the passive nodes converge simultaneously to the same value. The local information exchange among the nodes is dictated by a connected graph. By using the criterion of collective observability, a novel distributed adaptive estimation scheme is introduced via adaptive observer where the nodes are allowed to have different sensor modalities. Using the estimated information, a subset of active and passive nodes, referred to as mobile nodes, can track the moving target. By using a constant state feedback controller at each mobile node, the state and parameter estimation as well as the tracking errors are shown to be uniformly ultimately bounded. Simulation results verify theoretical claims.

AbstractUnderstanding structure‐fluorescence correlation is very helpful for the design of fluorescent probes. In this paper, a donor‐acceptor‐donor (D‐A‐D) type NIR‐II fluorophore with benzobisthiadiazole as the acceptor and triphenyl amine as the donor, and its three derivatives bearing respectively amino, tert‐butyloxycarbonyl amino and phenylazo groups in donor moieties, are synthesized. Their electronic structures and optical properties are investigated via theoretical and experimental studies. It is found that all the three types of substituents significantly influence its fluorescent properties and the phenylazo groups dramatically enhance its quantum yield (QY). To achieve biological applications and maintain high QY in aqueous environments, the phenylazo‐containing fluorophore is encapsulated in polystyrene‐co‐poly(ethylene glycol) micelles. The obtained fluorescent micelles have a QY of ≈3.51% in 1000–1500 nm in aqueous medium that is among the highest of the organic NIR‐II probes reported so far for biological imaging. The high QY enables the in vivo imaging of the micelle‐administered mice to be conducted with high speed and quality. As an application example, ultrafast NIR‐II imaging of intravenously injected mice is performed and used to determine their cardiac cycle and heart rate. The micelles also significantly accumulate in tumors after tail‐vein injection and exhibit great application potentials in tumor detection.

Published: January 2020

AbstractFabric has long‐term and the closest relationship to humans and is one of the measures of human progress and civilization. Functional fabrics are vigorously developed over the past few decades due to the explosive increase in portable electronic products. Fall detection is becoming increasingly important with the recent rapid aging of the population. Here, a pressure‐sensitive and large‐scale carpet for self‐powered fall detection, which is based on the textile‐triboelectric nanogenerators (t‐TENGs) arrays inlaid in common textile, is proposed. Core–shell yarns with conductive fibers as the core and common clothing fibers as the shell fabricated by a commercially available weaving method are used to constructed the smart t‐TENGs. The fabricated smart carpet exhibits desirable features including high sensitivity, fast response time, scalable production, comfortability, washability, and compatibility with existing home decoration. Furthermore, apart from highly integrated data acquisition and processing, arrangement of t‐TENGs cells and trigger algorithm are deliberately designed to effectively and simply realize real‐time and self‐powered falling behavior monitoring. Possessing these unique merits, the proposed system demonstrates great potential in more humanized medical healthcare systems and can be applied to innumerable families.

Published: January 2020

AbstractPolaritons, resulting from the hybridization of light with polarization charges formed at the boundaries between media with positive and negative dielectric response functions, can focus light into regions much smaller than its associated free‐space wavelength. This property is paramount for a plethora of applications in nanophotonics, ranging from biological sensing to photocatalysis to nonlinear and quantum optics. In the two‐dimensional (2D) limit, represented by atomically thin and van der Waals (vdW) materials of single‐layers bound by weak vdW attraction, polaritons are characterized by extremely small wavelengths associated with extreme optical confinement, and furthermore can exhibit long lifetimes, electrical tunability, and extreme sensitivity to their dielectric environment, among many other desirable qualities in nano‐optical device applications. Here, the fundamentals of polaritons in atomically thin materials are summarized, emphasizing plasmon and exciton polaritons, their strong light–matter interactions, and nonlinear plasmonics. More specifically, this review opens with a pedagogical discussion of plasmons in extended and nanostructured graphene, providing a classical electrodynamical model in a nonretarded theoretical framework, and the ultraconfined acoustic plasmons supported by hybrid graphene–dielectric–metal structures. In addition, the basic principles are introduced and the recent developments on nonlinear graphene plasmonics and on strong coupling physics with atomically thin transition metal dichalcogenides are reviewed. Finally, potentially new, promising research directions in the burgeoning field of 2D nanophotonics are identified.
