In this case, efficient task allocation plays a key role in improving the performance of the IWSNs. Task allocation in IWSNs is a nondeterministic polynomial (NP) hard problem whose complexity increases with an increase in node and task size. In this study, chaotic elite clone particle swarm optimization (CECPSO) was proposed. The algorithm first introduces the chaos theory to optimize the initial population. Subsequently, an elite cloning strategy was designed, which not only accelerated the exploration of the solution space and improved the accuracy of the solution but also avoided the problem of falling into the local optimal solution in the early stage through the dynamic adjustment strategy. In addition, the algorithm employs an exponential nonlinear decreasing inertia weight function that balances local and global search capabilities. By comparing the performance of CECPSO, Particle Swarm Optimization (PSO), Genetic Algorithm (GA), and Simulated Annealing (SA) in different experimental scenarios, we found that CECPSO is superior to PSO, GA, and SA in terms of the convergence rate and overall performance. Under the conditions of 40 sensors and 240 tasks, CECPSO's performance improvement of CECPSO relative to PSO, GA, and SA reached 6.6%, 21.23%, and 17.01%, respectively. Experimental results show that the proposed algorithm can effectively improve the overall performance of IWSNs.","PeriodicalId":21811,"journal":{"name":"Scientific Reports","volume":"15 1","pages":"35530"},"PeriodicalIF":3.9,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145275644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The exposure was magnesium sulphate administration during intensive care unit (ICU) stay. The primary outcome was in-hospital mortality. A 1:1 ratio propensity score matching (PSM) was performed; multivariable analyses were conducted to account for potential confounders. The study cohort comprised 5,499 patients before PSM and 1,282 patients after PSM. For PSM, the in-hospital mortality rates were 32.29% (207/641) and 37.44% (240/641) in the magnesium sulphate use and no-use groups, respectively. Magnesium sulphate use was associated with lower in-hospital mortality (hazard ratio [HR], 0.71; 95% confidence interval [CI], 0.59-0.85; P < 0.001) and lower ICU 30-day mortality (HR, 0.75; 95% CI, 0.62-0.90; P = 0.002).

Participants were presented with four investment funds in a within-subject design where past performance (i.e., positive vs. negative) and typology (i.e., socially responsible vs. traditional) were manipulated. We examined how expertise, the fund's past performance, and the type of fund influence participants' assessment of the funds (i.e., emotional reactions, perceived risk, and expected return) and their willingness to sell them. Our findings confirmed that lay people are more influenced by past performance and funds' characteristics when assessing their emotional reactions and the funds' risk and return, while expert investors' assessments remain relatively consistent across conditions.

This model considers the length (l), radius (R) and amount of CNFs, interphase depth, percolation onset (PT), waviness, network portion, and tunneling length (d), by reasonable and meaningful equations. The proposed model is verified through the measured conductivity of samples and by studying the features' influences on the PCNF conductivity. The model calculations display respectable fitting with the experimented facts from numerous CNF samples. Additionally, all factors sensibly affect the conductivity of PCNFs. Longer and thinner CNFs, higher CNF amount, thicker interphase, shorter tunnels, and lower percolation onset lead to higher conductivity in PCNF. R > 50 nm and l < 15 μm produce an insulative composite, but the top conductivity of 0.21 S/m is displayed at R = 10 nm and l = 25 μm. Accordingly, narrower and bigger nanofibers can improve the conductivity. Furthermore, an insulative material is produced by PT = 0.04 nm and d > 5 nm, nevertheless the conductivity maximizes to 0.25 S/m at the least values of PT = 0.01 nm and d = 2 nm. These results disclose that the lowest percolation onset and narrowest tunnels yield the highest conductivity in the composite.","PeriodicalId":21811,"journal":{"name":"Scientific Reports","volume":"15 1","pages":"35459"},"PeriodicalIF":3.9,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145275845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Short-time Fourier transform (STFT) is a valuable tool for analyzing non-stationary signals in geophysics, and researchers have utilized it to solve various geophysical problems including spectral decomposition, seismic data interpolation and signal filtering. In this paper, a novel time-frequency method named short-time Fourier transform based multisynchrosqueezing transform using a second-order signal model (FMSST2) is introduced to analyze seismic data. The FMSST2 combines the multisynchrosqueezing framework using an iterative reassignment procedure and a second-order signal model to concentrate the energy in the time-frequency map. Moreover, The FMSST2 allows for signal reconstruction with a high accuracy. Two synthetic examples are employed to validate the effectiveness of the FMSST2 method, and the results show that the FMSST2 method does a good job in terms of energy-concentration and noise robustness compared to some classic TFA methods such as the STFT, STFT-Based synchrosqueezing transform (FSST) and multisynchrosqueezing transform (MSST). Applications on field data further demonstrate the potential of the FMSST2 method in characterizing hydrocarbon reservoir, making it a promising time-frequency resolution enhancement tool in seismic data analysis.","PeriodicalId":21811,"journal":{"name":"Scientific Reports","volume":"15 1","pages":"35476"},"PeriodicalIF":3.9,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145275851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, if part of the input data is unavailable due to missing or corrupted data, a significant bias can occur, a problem that may be relatively more critical in medical applications where patients may be negatively affected. In this study, we propose the Laplacian filter attention with style transfer generative adversarial network (LASTGAN) to solve the problem of missing sequences in brain tumor magnetic resonance imaging (MRI). Our method combines image imputation and image-to-image translation to accurately synthesize specific sequences of missing MR images. LASTGAN can accurately synthesize both overall anatomical structures and tumor regions of the brain in MR images by employing a novel attention module that utilizes a Laplacian filter. Additionally, among the other sub-networks, the generator injects a style vector of the missing domain that is subsequently inferred by the style encoder, while the style mapper assists the generator in synthesizing domain-specific images. We show that the proposed model, LASTGAN, synthesizes high quality MR images with respect to other existing GAN-based methods. Furthermore, we validate the use of LASTGAN for data imputation or augmentation through segmentation experiments.","PeriodicalId":21811,"journal":{"name":"Scientific Reports","volume":"15 1","pages":"35453"},"PeriodicalIF":3.9,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145275866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Congenital transmitted CMV is associated with severe neurological sequelae and can cause life-threatening disease in immunocompromised individuals. Although antibodies are generally presumed to correlate with protection, their long-term dynamics remain poorly understood. We aimed to determine the longevity of CMV-specific antibodies in a low-income setting in Kilifi County, Kenya. To track long-term antibody dynamics, we conducted longitudinal surveillance of annually collected serum samples and assayed for antibodies against the CMV tegument phosphoprotein (pp150). The duration of effective immunity against re-infection was estimated using piecewise regression modelling. Serum antibody to CMV was measured in 123 children recruited within the first five years of life and sampled annually over a median of 10 years (range: 7-14). Antibodies to the CMV pp150 showed a cyclic trend of acquisition and loss at the population level. Individually, we observed early antibody acquisition, followed by decline and rebound. Regression analysis identified a 7.57-year inflection point in antibody trajectories, marking a transition from waning to re-accumulation - potentially reflecting natural boosting events in a population where CMV infection occurs early in life. The data show a clear pattern of early natural infection, followed by repeated patterns of antibody acquisition, loss, and re-acquisition over the first decade and a half of life.","PeriodicalId":21811,"journal":{"name":"Scientific Reports","volume":"15 1","pages":"35541"},"PeriodicalIF":3.9,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145275872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their demographics, history of drug use, and stimulant use disorder severity were assessed with structured clinical interviews.

None of severity, education, recent stimulant use, and lifetime duration of use, were found to be associated with cognition. While stimulant users exhibited some modest cognitive declines at baseline, no further substantial cognitive deterioration was observed over the one-year study period.
