With the development of computation capability and future 5 G, the ACP theory(i.e., artificial systems,computational experiments, and parallel computing) will play a much more crucial role in modeling and control of complex systems like commercial and academic buildings. The necessity of making accurate predictions of energy consumption out of a large number of operational parameters has become a crucial problem in smart buildings. Previous attempts have been made to seek energy consumption predictions based on historical data in buildings. However, there are still questions about parallel building consumption prediction mechanism using a large number of operational parameters. This article proposes a novel hybrid deep learning prediction approach that utilizes long short-term memory as an encoder and gated recurrent unit as a decoder in conjunction with ACP theory. The proposed approach is tested and validated by real-world dataset, and the results outperformed traditional predictive models compared in this paper.展开更多

The problem related to immune strategy and laboratory- acquired infections which is being raised, analyzed and explored plays an active and instructive role in vaccinia virus related researches and laboratory- acquired infections, and also helps to recommend and develop relevant immune strategy for future vaccine control of such infections.展开更多

Laboratory rodents can be obtained in one of several categories defined by the degree to which they harbour microflora, whether commensal, potentially pathogenic or pathogenic. It is now possible to specify the different species of organism that are tolerated and those that are not tolerated, In such model laboratory animals it is essential to raise and maintain them in circumstances under which microorganisms that would not be tolerated cannot enter the production system.展开更多

文摘A P-band polarimetric synthetic aperture radar(PolSAR)sensor has deep penetration ability into and through the vegetation canopies in forested environments.Thus,the sensor is of great potential to accurately assess forest parameters such as coverage,stand density,and tree height.Unfortunately,the radar backscatter from complex terrain can adversely impact the backscatter from trees or forests,and forest parameters assessed can be erroneous.Thus,reducing the topographic impact is an urgent must.In this study,a topographic compensation algorithm has been studied.To assess the algorithm’s validity and effectiveness,we applied it to P-band PolSAR datasets in four forested areas in the US.Trees in the forest stands have diverse species,and the topographic conditions of the terrain differ.Significant topographic impact on the P-band PolSAR data exists before the topographic compensation algorithm.After the algorithm,the impact decreases noticeably qualitatively and quantitatively.The algorithm is valid and effective in reducing the topographic influence on the PolSAR data and,consequently,provides a better chance of retrieving accurate forest parameters.

文摘Protein glycosylation and phosphorylation,as two of the most important protein post-translational modifications(PTMs),play key roles in living organisms.However,glycopeptides and phosphopeptides have low abundance in biological samples.In addition,the low ionization efficiency and the severe signal interference in the presence of other peptides present great difficulties for their direct mass spectrometry(MS)analysis.Therefore,it is important to develop feasible enrichment strategies to pretreat glycopeptides and phosphopeptides in complex samples before MS detection.This paper reviews the application of various magnetic nanomaterials(MNMs)in glycopeptides and phosphopeptides in the last decade,with emphasis on the enrichment principles,the design and synthesis process of the materials,and the effectiveness of the application in biological samples.In addition,possible future trends and potential challenges are presented.

文摘Ionospheric scintillation refers to rapid radio signal amplitude and phase fluctuations due to small-scale irregularities in the ionosphere.Occurring primarily at equatorial and low latitudes,scintillation is linked to equatorial plasma bubbles(EPBs),regions of depleted plasma density that form after sunset.Ionospheric scintillation typically occurs from post-sunset hours until midnight.Post-sunset EPBs can be enhanced or suppressed during geomagnetic storms,depending on local sunset timing and how it relates to the storm's main or recovery phases.This study analyzes ionospheric scintillation in Indonesia,located at low geomagnetic and geographic latitudes,during geomagnetic events from 2003 to 2024.Using the S4 index,scintillation was examined with data from seven observation stations during geomagnetic storm events.Geomagnetic activity was evaluated using Dst,SYM-H,and AE indices,employing Superposed Epoch Analysis(SEA)to assess scintillation occurrence linked to minimum SYM-H,defined as epoch 0 to represent the storm peak or the onset of recovery phase in each event.The analysis categorized geomagnetic storms into weak-moderate(–100 nT<min.Dst≤–30 nT)and strong(min.Dst≤–100 nT),and examined their dependence on the local time of minimum SYM-H.Results indicate that scintillation first appears~6 hours after epoch 0 in weak-moderate geomagnetic storms,and~12 hours after epoch 0 in strong geomagnetic storms.The average AE index returns to its baseline value(quiet condition)~6 and~12 hours after epoch 0 for weak-moderate and strong geomagnetic storms,respectively.Further analysis based on the classification of the local time of epoch 0 shows that scintillation occurrence is not observed in post-sunset hours when epoch 0 falls between 16:00 and 19:00 LT for weak-moderate geomagnetic storms.In strong geomagnetic storms,scintillation occurrence during post-sunset hours is absent when epoch 0 is between 10:00 and 19:00 LT.Notably,when the minimum SYM-H(epoch 0)nearly coincides with local sunset,scintillation activity occurs around sunset in both weak-moderate and strong geomagnetic storms.Furthermore,when epoch 0 falls within midnight until early morning,scintillation can be generated in the post-sunset hours before epoch 0.Still,post-midnight scintillation is not observed in the equatorial region during the recovery phase of either weak-moderate and strong storm events.Our findings show that when sunset falls before or coincide with epoch 0,the likelihood of post-sunset EPB and scintillation increases,due to the prompt-penetration electric field(PPEF)in the main phase of storm.The disturbance dynamo electric field(DDEF)in the recovery phase driven by equatorward winds from auroral Joule heating operates for at least 6-and 12-hours post-epoch 0 in the cases of weak-moderate and strong geomagnetic storms,respectively.When the local sunset falls within these operational DDEF periods,post-sunset EPBs will likely be suppressed,inhibiting ionospheric scintillation during post-sunset hours.Finally,this study provides essential information for developing more accurate ionospheric scintillation prediction models in space weather services in equatorial regions.
文摘Pulmonary embolism(PE)can range from minor,asymptomatic blood clots to life-threatening emboli capable of obstructing pulmonary arteries,potentially leading to cardiac arrest and fatal outcomes.Due to this significant mortality risk,risk stratification is essential following PE diagnosis to guide appropriate therapeutic intervention.This study proposes a machine learning-based methodology for PE risk stratification,utilizing clinical data from a cohort of 139 patients.The predictive framework integrates an enhanced binary Honey Badger Algorithm(BCCHBA)with the K-Nearest Neighbor(KNN)classifier.To comprehensively evaluate the performance of the core optimization algorithm(CCHBA),a series of benchmark function tests were conducted.Furthermore,diagnostic validation tests were performed using real-world PE patient data collected from medical facilities,demonstrating the clinical significance and practical utility of the BCCHBA-KNN system.Analysis revealed the critical importance of specific indicators,including neutrophil percentage(NEUT%),systolic blood pressure(SBP),oxygen saturation(SaO2%),white blood cell count(WBC),and syncope.The classification results demonstrated exceptional performance,with the prediction model achieving 100%sensitivity and 99.09%accuracy.This approach holds promise as a novel and accurate method for assessing PE severity.
