In this work, we have made a comprehensive evaluation of the performances of existingtop RNA secondary structure prediction methods, including five deep-learning (DL) based methods and five minimum freeenergy (MFE) based methods. First, we made a brief overview of these RNA secondary structure prediction methods.Afterwards, we built two rigorous test datasets consisting of RNAs with non-redundant sequences and comprehensivelyexamined the performances of the RNA secondary structure prediction methods through classifying the RNAs into differentlength ranges and different types. Our examination shows that the DL-based methods generally perform better thanthe MFE-based methods for RNAs with long lengths and complex structures, while the MFE-based methods can achievegood performance for small RNAs and some specialized MFE-based methods can achieve good prediction accuracy forpseudoknots. Finally, we provided some insights and perspectives in modeling RNA secondary structures.展开更多

The Weibull distribution and wind speed extrapolation methods are powerful mathematical tools for efficiently predicting the frequency distribution of wind speeds at a site. Hourly wind speed and direction data were collected from the National Aeronautics and Space Administration (NASA) website for the period 2013 to 2023. MATLAB software was used to calculate the distribution parameters using the graphical method and to plot the corresponding curves, while WRPLOTView software was used to construct the wind rose. The average wind speed obtained is 3.33 m/s and can reach up to 5.71 m/s at a height of 100 meters. The wind energy is estimated to be 1315.30 kWh/m2 at a height of 100 meters. The wind rose indicates the prevailing winds (ranging from 3.60 m/s to 5.70 m/s) in the northeast-east direction.展开更多

In this work, we have made a comprehensive evaluation of the performances of existingtop RNA secondary structure prediction methods, including five deep-learning (DL) based methods and five minimum freeenergy (MFE) based methods. First, we made a brief overview of these RNA secondary structure prediction methods.Afterwards, we built two rigorous test datasets consisting of RNAs with non-redundant sequences and comprehensivelyexamined the performances of the RNA secondary structure prediction methods through classifying the RNAs into differentlength ranges and different types. Our examination shows that the DL-based methods generally perform better thanthe MFE-based methods for RNAs with long lengths and complex structures, while the MFE-based methods can achievegood performance for small RNAs and some specialized MFE-based methods can achieve good prediction accuracy forpseudoknots. Finally, we provided some insights and perspectives in modeling RNA secondary structures.
文摘Understanding the wind power potential of a site is essential for designing an optimal wind power conditioning system. The Weibull distribution and wind speed extrapolation methods are powerful mathematical tools for efficiently predicting the frequency distribution of wind speeds at a site. Hourly wind speed and direction data were collected from the National Aeronautics and Space Administration (NASA) website for the period 2013 to 2023. MATLAB software was used to calculate the distribution parameters using the graphical method and to plot the corresponding curves, while WRPLOTView software was used to construct the wind rose. The average wind speed obtained is 3.33 m/s and can reach up to 5.71 m/s at a height of 100 meters. The wind energy is estimated to be 1315.30 kWh/m2 at a height of 100 meters. The wind rose indicates the prevailing winds (ranging from 3.60 m/s to 5.70 m/s) in the northeast-east direction.

文摘Placenta abnormalities,which are collectively termed as placenta accreta spec-trum(PAS),are increasing globally in the female population due to the large nu-mber of cesarean sections performed worldwide.PAS represents a rare but life-threatening occurrence that can lead to an increased risk of postpartum hemorr-hage due to the abnormal infiltration of the chorionic villi in the uterine wall up to the adjacent structures.Performing a prophylactic occlusion of the iliac arteries for a brief amount of time using balloon-occlusion endovascular catheters in patients with PAS can help control unwanted blood losses during cesarean delivery or postpartum demolition surgery.The aim of this narrative minireview was to pro-vide an overview of the aspects about prophylactic occlusion with endovascular balloons in patients with PAS and to analyze current evidence on this topic.In particular,this minireview included an overview of indications,patient selection,type of materials and devices used,technical advice and suggestions,clinical outcomes,and complications to give every interventional radiologist as well as every gynecologist and midwife all the information that is needed to address this particular condition in a safe and prompt manner.
文摘Purpose–For the commonly used concrete mix for railway tunnel linings,concrete model specimens were made,and springback and core drilling tests were conducted at different ages.The springback strength was measured to the compressive strength of the core sample with a diameter of 100mm and a height-to-diameter ratio of 1:1.By comparing the measured strength values,the relationship between the measured values under different strength measurement methods was analyzed.Design/methodology/approach–A comparative test of the core drilling method and the rebound method was conducted on the side walls of tunnel linings in some under-construction railways to study the feasibility of the rebound method in engineering quality supervision and inspection.Findings–Tests showed that the rebound strength was positively correlated with the core drill strength.The core drill test strength was significantly higher than the rebound test strength,and the strength still increased after 56 days of age.The rebound method is suitable for the general survey of concrete strength during the construction process and is not suitable for direct supervision and inspection.Originality/value–By studying the correlation of test strength of tunnel lining concrete using two methods,the differences in test results of different methods are proposed to provide a reference for the test and evaluation of tunnel lining strength in railway engineering.
文摘Objective:To observe the control effect of interventional therapy combined with lenvatinib and sintilimab in patients with intermediate and advanced liver cancer.Methods:82 patients with intermediate and advanced liver cancer who visited from January 2022 to January 2025 were selected as samples and randomly divided into two groups.Group A received interventional therapy combined with lenvatinib and sintilimab,while Group B received interventional therapy combined with lenvatinib.Disease remission rate,adverse reactions,liver function indicators,and tumor marker indicators were compared between the two groups.Results:The disease control rate(DCR)in Group A was higher than that in Group B(P<0.05).There was no difference in adverse reaction rates between Group A and Group B(P>0.05).Total bilirubin(TBil),aspartate aminotransferase(AST),and alanine aminotransferase(ALT)levels in Group A were lower than those in Group B(P<0.05).Carcinoembryonic antigen(CEA),alpha-fetoprotein(AFP),and alpha-L-fucosidase(AFU)levels in Group A were also lower than those in Group B(P<0.05).Conclusion:Intermediate and advanced liver cancer patients receiving interventional therapy combined with lenvatinib and sintilimab showed reduced tumor marker levels,lessened liver function damage,and a high disease control rate and treatment safety.
文摘Liver cancer presents unique challenges due to its systemic impact and complex treatment modalities.Patients often experience a range of complications,including cardiovascular,renal,hematological,and metabolic abnormalities,which can significantly affect treatment outcomes and quality of life.This article emphasizes the integration of multidisciplinary strategies and artificial intelligence-driven diagnostics,which have the potential to improve patient outcomes by optimizing early detection and targeted management of these complications.A recent study on 60 liver cancer patients undergoing interventional therapy highlighted the importance of recognizing and managing these complications.This article offers an overview of systemic complications in liver cancer,focusing on pathophysiological mechanisms,risk factors,and strategies to improve care.By addressing gaps in the existing literature and proposing future research directions,it underscores the importance of comprehensive,patient-centered approaches to refine therapeutic strategies.
文摘Gastrointestinal bleeding(GIB)presents a significant challenge for patients with hematologic malignancies,especially those with severe thrombocytopenia.Although endoscopic intervention is frequently used in managing GIB,its safety and effectiveness in this high-risk group remain unclear.A recent study by Alhumayyd et al provided insight into this issue.However,it has notable limitations,including its retrospective nature,small sample size,and failure to adjust for important confounding factors such as disease severity,hemodynamic status,and platelet function.The study’s findings indicated that urgent endoscopy may help decrease the incidence of recurrent bleeding;however,it did not show a clear benefit in terms of mortality.Future research ought to prioritize prospective,multicenter studies that employ standardized protocols and incorporate risk stratification models to better understand the impact of endoscopic treatment for GIB in these patients.Additionally,integrating platelet function assays could improve clinical decision-making.Addressing these research gaps is essential for improving patient outcomes and developing effective guidelines for managing GIB in individuals with thrombocytopenia.

文摘Efficient and accurate simulation of unsteady flow presents a significant challenge that needs to be overcome in computational fluid dynamics.Temporal discretization method plays a crucial role in the simulation of unsteady flows.To enhance computational efficiency,we propose the Implicit-Explicit Two-Step Runge-Kutta(IMEX-TSRK)time-stepping discretization methods for unsteady flows,and develop a novel adaptive algorithm that correctly partitions spatial regions to apply implicit or explicit methods.The novel adaptive IMEX-TSRK schemes effectively handle the numerical stiffness of the small grid size and improve computational efficiency.Compared to implicit and explicit Runge-Kutta(RK)schemes,the IMEX-TSRK methods achieve the same order of accuracy with fewer first derivative calculations.Numerical case tests demonstrate that the IMEX-TSRK methods maintain numerical stability while enhancing computational efficiency.Specifically,in high Reynolds number flows,the computational efficiency of the IMEX-TSRK methods surpasses that of explicit RK schemes by more than one order of magnitude,and that of implicit RK schemes several times over.

文摘In this paper,a new technique is introduced to construct higher-order iterative methods for solving nonlinear systems.The order of convergence of some iterative methods can be improved by three at the cost of introducing only one additional evaluation of the function in each step.Furthermore,some new efficient methods with a higher-order of convergence are obtained by using only a single matrix inversion in each iteration.Analyses of convergence properties and computational efficiency of these new methods are made and testified by several numerical problems.By comparison,the new schemes are more efficient than the corresponding existing ones,particularly for large problem sizes.
文摘Objective:To analyze the treatment effect of standardized bronchoscopic interventional therapy(i.e.,interventional therapy)on airway stenosis.Methods:Forty patients with airway stenosis admitted to the hospital between September 2022 and September 2024 were selected and randomly divided into two groups using a random number table.The experimental group received interventional therapy,while the reference group received conventional treatment.The total effective rate,degree of airway stenosis,shortness of breath score,and lung function indicators were compared.Results:The total effective rate in the experimental group was higher than that in the reference group.The proportion of mild stenosis in the degree of airway stenosis was higher in the experimental group than in the reference group.The shortness of breath score was lower in the experimental group than in the reference group.The lung function indicators were better in the experimental group than in the reference group(P<0.05).Conclusion:Interventional therapy is effective for patients with airway stenosis,as it can reduce the degree of stenosis,improve symptoms of shortness of breath,and protect patients’lung function.
