Authors: Xia Hui , Shi Yong , Hou Xinyu 
Published: November 2024

ABSTRACTThis paper proposed a segment‐compensated printed circuit board (PCB) coil for multirelay wireless power transfer (WPT) system. The PCB coil is designed with variable width to improve the system transfer efficiency, and the segmented compensation method is applied to avoid the high voltage stress on resonant capacitors in case of the multirelay WPT system with a low load resistance operating at a constant voltage frequency. The segmented compensation capacitors are integrated into the PCB coil, so as to constitute the compact coupler used in multirelay WPT system. The optimization procedure of the segment‐compensated PCB coil is also provided. The quality factor of the PCB coil can be improved by optimizing the proportional coefficients of width variation. The voltage of capacitors can be reduced by optimizing the number of segments. A physical variable‐width PCB coil with 3 segments is constructed. The experimental prototypes of the three‐coil, four‐coil, and five‐coil WPT systems are built. The experimental results show that the voltage of the segmented compensation capacitors on each coil is almost uniformly distributed and does not exceed 250 V when the input voltage is 50 V and the load resistance is 10 Ω. Compared with the multirelay WPT system using the equal‐width PCB coil, the multirelay WPT system using the PCB coil designed in this paper has higher output power and higher efficiency.

Published: November 2024

ABSTRACTThe ability of the current global healthcare system to continue providing high‐quality medical care has been questioned. By using delay‐tolerant networks (DTNs) in healthcare management, people that spend a lot of time treating illnesses are exposed to more people while also putting their lives in danger. Unsupervised approach‐based node localization and secure routing in DTNs are developed in the proposed method. The proposed adaptive density‐based localization algorithm is constructed in two modules. The entire network is clustered depending on density utilizing density‐based spatial clustering of applications with noise (DBSCAN). An RSA‐based location estimation algorithm is employed to identify the unlocalized node within each cluster. After finding the location of each node, routing mechanism is carried out. An adaptive spray and wait routing strategy is utilized in the proposed method. When a node only has one copy of a message, the spray and wait, routing mechanism moves the relay node while it waits for the destination to be countered. Then modified DNA encryption algorithm is applied for secure data transmission. It is used for encrypting the information before storing it in the network. The trusted center will generate the private key needed for encrypting the data based on the sensitivity level of the information. This proposed algorithm is tested with several metrics which attain better performance, like 94% localization accuracy, 6% localization error, average residual energy of 93%, 5.7 Mbps throughput, 18% encryption time, and 14% decryption time. Thus, the techniques used in the proposed approach are the best choice for node localization, energy efficiency, and secure data transmission in DTN.

AbstractBackgroundSince it is difficult for expert endoscopists to diagnose early gastric cancer in post‐eradication status, it may be critical to evaluate the stratification of high‐risk groups using the advance of gastric atrophy or intestinal metaplasia. We tried to determine whether the combination of endoscopic artificial intelligence (AI) diagnosis for the evaluation of gastric atrophy could be a useful tool in both pre‐ and post‐eradication status.Methods270 Helicobacter pylori‐positive outpatients (Study I) were enrolled and Study II was planned to compare patients (n = 72) with pre‐eradication therapy with post‐eradication therapy. Assessment of endoscopic appearance was evaluated by the Kyoto classification and Kimura‐Takemoto classification. The trained neural network generated a continuous number between 0 and 1 for gastric atrophy.ResultsThere were significant associations between the severity of gastric atrophy determined by AI endoscopic diagnosis and not having a regular arrangement of collecting venules in angle, visibility of vascular pattern, and mucus using Kyoto classification in H. pylori‐positive gastritis. There were significant differences (p = 0.037 and p = 0.014) in the severity of gastric atrophy between the high‐risk group and low‐risk group based on the combination of Kimura‐Takemoto classification and endoscopic AI diagnosis in pre‐ and post‐eradication status. The area under the curve values of the severity of gastric atrophy (0.674) determined by the combination of Kimura‐Takemoto classification and gastric atrophy determined by AI diagnosis was higher than that determined by Kimura‐Takemoto classification alone in post‐eradication status.ConclusionA combination of gastric atrophy determined by AI endoscopic diagnosis and Kimura‐Takemoto classification may be a useful tool for the prediction of high‐risk groups in post‐eradication status.

ABSTRACTWe report on an adult male green turtle (Chelonia mydas) feeding on fallen leaves from a terrestrial tree, frangipani (Plumeria rubra), in the waters in front of Cabuyal—a known sea turtle nesting beach—on the north Pacific coast of Costa Rica. This observation, in conjunction with similar reports worldwide, corroborates that terrestrial leaves may be a common food item for green turtles in areas near mangrove forests or coastal deciduous trees. Our observation also indicates that male turtles may feed during reproductive periods if food is available.

AbstractFlight initiation distance (FID), the distance at which an organism begins to flee from an approaching threat, is a major component of antipredator escape behavior and a potential indicator of threat perception in fishes. In this study, we analyzed the FID of three important rocky‐reef fish species targeted by spearfishers, which are of commercial and recreational importance. We tested predictions that FID to a diver threat increases with the following factors: (1) fish body size, (2) less restricted access regimes, and (3) increased historical fishing pressure. We studied three size ranges of three rocky‐reef fish species, in three different access regimes (i.e., open access, territorial user rights for fishery areas, no‐take marine protected areas), and in two regions (northern and central region with different levels of fishing pressure depending on the species). We conducted an ANOVA to analyze pairwise interactions. We used the mean square criterion to select the models that best explained the variation of our response variable. Our findings indicate that FID can be distinctly elucidated by factors such as individual size, species, access regimes, and regions. Additionally, our models show that interactions involving regions and either species or size further contribute to explain FID variability. FID was higher in larger fishes and those of higher commercial value, outside marine reserves and in the region with the highest historical fishing pressures (based on landings data). This study supports the predictions that increased FID is associated with the threat posed by spearfishing activities. Furthermore, our findings indicate that spearfishing may already be altering the behavior of rocky‐reef fishes on the north‐central coast of Chile.

AbstractIn this research, we introduce new members to the [Fe(bzL)(NCE)2] complex series by incorporating NCS− and NCBH3− as co‐ligands, expanding on our established tetradentate bzL ligand. The synthesis of three isostructural structures has allowed for a systematic tuning of SCO temperatures, with T1/2 values ranging from 85 K for the S‐α complex, featuring approximately 15 K thermal hysteresis, to 194 K for the Se‐α complex, and a stable low‐spin state up to 300 K for the B‐α complex. This work demonstrates the efficacy of modulating SCO properties through variation of the NCE− ancillary ligands. Furthermore, we conducted a comparative analysis of 21 analogs within this family. This analysis aims to elucidate the similarities and differences among the complexes and their correlation with SCO properties, furthering our understanding of the structural determinants that influence SCO behavior.

Published: November 2024

AbstractFour novel fluorescence active ligands (1–4) consisting of a 1H‐tetrazol‐1‐yl moiety as coordinating unit and a 4,4‐difluoro‐4‐bora‐3a,4a‐diaza‐s‐indacene (BODIPY) derivative as fluorophore, bridged via alkyl (‐(CH2)n‐, n=1–3) or benzyl (‐CH2‐C6H4‐) spacers were designed. Successful synthesis is demonstrated by multinuclear NMR spectroscopy, as well as powder and single crystal XRD analysis. The methylene bridged ligand 2 (4,4‐difluoro‐1,3,5,7‐tetramethyl‐8‐[(1H‐tetrazol‐1‐yl)methyl]‐4‐bora‐3a,4a‐diaza‐s‐indacene) crystallizes in different polymorphs and solvatomorphs, in contrast to the other three ligands, which show no polymorphism under identical conditions. Photophysical studies revealed high fluorescence quantum yields (69 – 95 %) in solution for the ‐(CH2)2‐ bridged ligand 3 (4,4‐difluoro‐1,3,5,7‐tetramethyl‐8‐[(1H‐tetrazol‐1‐yl)ethyl]‐4‐bora‐3a,4a‐diaza‐s‐indacene) and the ‐(CH2)3‐ bridged ligand 4 (4,4‐difluoro‐1,3,5,7‐tetramethyl‐8‐[(1H‐tetrazol‐1‐yl)propyl]‐4‐bora‐3a,4a‐diaza‐s‐indacene). Non‐radiative decay due to rotational motion of the 1H‐tetrazol‐1‐yl‐ and/or ‐CH2‐C6H4‐ moiety for 2 and 1 (4,4‐difluoro‐1,3,5,7‐tetramethyl‐8‐[4‐((1H‐tetrazol‐1‐yl)methyl)phenyl]‐4‐bora‐3a,4a‐diaza‐s‐indacene) respectively leads to reduced quantum yields of ≥35 %. Complete fluorescence quenching upon aggregation is prevented by installation of the sterically demanding 1H‐tetrazol‐1‐yl moiety and a spacer in meso‐position of the BODIPY core to elongate the intermolecular distances between two adjacent BODIPY cores. Detailed photophysical and crystallographic investigations are supported by theoretical calculations.

AbstractThe current study examines how mass and heat transfer affect mobility of Jeffrey fluid while taking sun radiation across the vertical plate into account. In the polyvinyl alcohol water base fluid, the study combines gyrotactic organisms with copper nanoparticles. Microorganisms classified as gyrotactic respond to gravitational and viscous forces by swimming and orienting themselves, which results in the formation of patterns known as bioconvection, which is the result of the collective movement of these microorganisms. The main goals are to address the growing uses of solar plates by creating a unique mathematical model for flow and thermal properties of the parabolic trough solar collector (PTSC) installed on solar panel. Sunlight is directed onto a single focal line by curved mirrors in PTSCs, which heat the fluid moving over the plate at this focused line. The momentum, heat, and mass equations are solved by the model using Fourier and Fick's laws. The Laplace transform is then used to convert the solution sets into dimensionless Partial differential equation (PDE) for the velocity, energy, and mass fields. The innovative aspect of this model is its in‐depth examination of non‐Newtonian nanofluids, which are boosted by the addition of gyrotactic organisms and copper nanoparticles to increase heat transfer efficiency. The impacts of several factors on flow characteristics, including the Lewis number, mass Grashof number, Grashof number for bioconvection, magnetic and electric parameters, Peclet number, chemical reaction parameter, and Prandtl number, are shown graphically. Increasing the radiation parameters and volume fraction results in a noticeable improvement in the temperature profile. By demonstrating the superior heat transfer capabilities of non‐Newtonian nanofluids in solar energy applications, this work advances the field. It is particularly relevant to microchip cooling, solar energy systems, and thermal energy systems. In summary, the work provides a comprehensive model that advances our understanding of heat and mass transfer in non‐Newtonian nanofluids that are exposed to ambient sunlight. In the future, the model will be employed in real solar energy systems to confirm its effectiveness. The findings have applications in the development of temperature control technology and solar energy systems that are more effective.

AbstractObjectiveIntegrated care pathways are essential for consistent, effective epilepsy care, offering equal access and quality regardless of socioeconomic status. They must align with the WHO Global Action Plan on Epilepsy, ensuring best practices and cost‐effective management. We describe the Finnish national epilepsy care pathway, which includes multiple levels of care, from initial diagnosis to long‐term care for all types of epilepsy, with a specific focus on rare and complex cases integrated with the European Reference Network (ERN) for Rare and Complex Epilepsies EpiCARE.MethodsIn 2017, the Finnish government nominated Kuopio University Hospital to coordinate diagnostics and care for severe epilepsy in Finland. A national multidisciplinary consensus panel, including specialists from both adult and pediatric neurology departments across all five Finnish university hospitals and from the patient organization, was established. The resulting pathway was adopted into the current Finnish evidence‐based current care guidelines for epilepsy.ResultsThe Finnish epilepsy care pathway focuses on timely referrals, continuity of care and enhanced communication between healthcare providers at different levels of care. Patient involvement is assured with an individualized digital application offering secure online messaging, a seizure calendar, and remote visits. The pathway enhances virtual consultations and includes regular national diagnostic multidisciplinary meetings for severe epilepsies before selected cases are consulted in ERN EpiCARE meetings.SignificanceThis Finnish model for epilepsy care provides a streamlined, multidisciplinary approach to diagnosis and treatment and combines modern digital tools, data sharing, and peer support. This pathway can serve to model how integrated healthcare systems can effectively manage complex conditions.Plain Language SummaryWe describe the Finnish national epilepsy care pathway, which includes multiple levels of care, from initial diagnosis to long‐term care for all types of epilepsy, with a specific focus on rare and complex cases integrated with the European Reference Network (ERN) for Rare and Complex Epilepsies EpiCARE.

AbstractAccurate estimations of the sediment transport capacity (Tc) are essential for soil erosion modelling. However, the applicability of existing Tc equations to colluvial soils with high steep slopes and high gravel content is limited. In this study, the variation of Tc with shear stress (τ), unit stream power (P) and stream power (ω) is investigated for different slopes and flow discharge. We also evaluate the applicability of the Yalin, Govers and GUEST equations (based on τ, P and ω, respectively) for estimating Tc on steep–slope colluvial deposits. Experiments were conducted using colluvial soil in a non‐erodible rill flume. The results reveal that Tc follows a power function with τ and ω and a linear function with P. The regression results of the three hydrodynamic parameters and Tc agree with the Tc equation forms of the corresponding equations. The Yalin equation, developed based on gently sloping erodible bed conditions, simulates overall low Tc values for steep sloping non‐erodible bed conditions (P.O.0.5–2 = 42.8%). The accuracy is significantly improved by correcting the sediment transport coefficient Kt (P.O.0.5–2 = 100%). The accuracy of the Govers‐simulated Tc values under steep slope conditions, based on gentle slope conditions, decreases with increasing slope gradient (P.O.0.5–2 = 37.14%), which is attributed to the large amount of coarse‐grained sediment present in this study. Thus, we retained the original form of the equation and further improved its accuracy by adjusting the coefficients (P.O.0.5–2 = 94.29%). As Tc increases, the GUEST equation can accurately simulate Tc. The accuracy is improved by calibrating the F‐value (P.O.0.5–2 = 100%). Using dimensional analysis, the equations built based on hydraulic conditions (excess current power, shear stress, flow velocity, etc.) and median particle size can accurately simulate Tc values (P.O.0.5–2 = 100%). These findings provide a basis for the development of erosion models for avalanche deposits on steep slopes.

ABSTRACTExcessive water consumption from liquid or reconstituted oral nutrition supplements may increase risk of fluid overload in renal patients. Nutri‐jelly, a ready‐to‐eat texture‐modified diet with 52.8% water, some protein, low potassium, phosphorus, and sodium, could be an alternative. However, its safety is unknown for adults undergoing hemodialysis (HD). This study investigated the short‐term physiological safety of Nutri‐Jelly intake and its preliminary impact on renal outcomes. A randomized open‐label, single‐arm, two‐sequence, two‐period cross‐over trial was conducted in 20 adults undergoing HD with inadequate protein intake (0.50 ‐ 0.70 g/ kg body weight/day). Participants were randomly allocated into 2 groups (n =10 each) and assigned in random sequence into both Without‐Jelly (HD 3 times during 7 days) and With‐Jelly periods (100 g Nutri‐Jelly twice daily along with HD 3 times during 7 days). A two‐week washout was between the periods. Outcome measures included adverse symptoms, changes in body weight, heart rate, blood pressure, and blood biochemical parameters relevant to renal outcomes. The results showed no intervention‐related adverse symptoms or significant changes in body weight, heart rate, systolic blood pressure, creatinine, albumin, and sodium. Potassium level and pre‐HD diastolic blood pressure were better controlled during the With Jelly than the Without Jelly Periods (p < 0.01 and p < 0.05, respectively). The eGFR was improved with no significant difference between the periods. The findings suggest that continuous intake of 100 g Nutri‐Jelly twice daily for 7 days is safe in adults undergoing hemodialysis. Its efficacy on renal‐related parameters warrants further investigations in long‐term studies.

Published: November 2024

ABSTRACTMeat preservation processes have been widely studied over time, especially those related to low temperatures (freezing and freeze‐drying); however, there is very little research that directly relates the effect of these processes on the structure of meat—and the main meat proteins—and how these changes affect some attributes of the final quality. Pork loin meat (Longissimus thoracis) was used, which was frozen–thawed and freeze‐dried‐rehydrated to subsequently evaluate changes in its chemical composition and physicochemical parameters such as water activity (aw), pH, and water‐holding capacity. Physical aspects such as color profile, surface myoglobin fraction, shear force, and histological sections were also evaluated, along with thermal analysis by modulated differential scanning calorimetry. The data obtained were analyzed through different statistical techniques. It was found that the freeze‐drying process significantly modifies the interactions of water with the rest of the meat components (p < 0.05), promoting differences concerning samples that were only frozen, allowing us to establish the importance of water and its associations with each other and with proteins on their effect on meat preservation processes at low temperatures.
