Considering the numerical information of indexes cannot be accurately obtained and can be defined as interval grey numbers, the interval grey numbers are defined as standard interval grey num- bers which are split in white part and grey part. The absolute degree of incidence and relative degree of incidence based on the interval grey numbers are constructed and their arithmetic are given. Finally, an example about commercial aircraft index selection illuminates the effectiveness of the model. The results show that the model can sort indexes better and can extend the grey incidence models significantly.展开更多

This study aims to determine the prevalence of delirium in critically ill patients diagnosed with SAP, and to identify risk factors associated with delirium in this patient population.METHODS: This was a retrospective, multicenter study, which enrolled adult patients diagnosed with SAP who admitted intensive care unit(ICU) for at least 24 h. Patient assessment was conducted using the Richmond Agitation-Sedation Scale(RASS) and the Confusion Assessment Method for the ICU(CAM-ICU). The cumulative incidence of delirium was determined. Demographic, clinical data, and length of ICU stay were compared between patients with and without delirium. A logistic regression model was employed to identify potential risk factors for delirium. RESuLTS: A total of 1,814 patients were included from seven hospitals in Anhui province, China. Delirium was observed in 25.2% of patients. Logistic regression analysis identified APACHE II scores(odds ratio [OR]=3.37, 95% confidence interval [CI]: 1.09–10.43, P=0.04), physical restraint(OR=11.11, 95%CI: 4.35–28.39, P<0.05), invasive mechanical ventilation(IMV)(OR=2.44, 95%CI: 1.41–4.25, P=0.002), and ICU length of stay ≥ 7 days(OR=3.14, 95%CI: 2.27–4.36, P<0.05) as independent risk factors of delirium.cONcLuSION: The present study revealed a substantial incidence of delirium in critically ill patients with SAP, associated with factors including APACHE II score, IMV, physical restraint, and prolonged ICU stays.展开更多

The evolutionary aspects of the incidence of antibiotic resistance in Salmonella strains no longer seem to attract much interest in the Central African Republic (CAR), although salmonellosis remains a health problem requiring national and international surveillance. Methodology: The study conducted at the National Laboratory of Clinical Biology and Public Health, Bangui, Central African Republic (LNBCSP) was a retrospective descriptive study. The study duration was five years (January 2019 to December 2023). The study sample consisted of patients who underwent bacteriological testing of stool, blood and urine samples for Salmonella at the LNBCSP in Bangui during this period. Study variables were age, sex, year and bacteriological test results. Statistical tests were used to compare incidences. Relative risks (RR) were calculated to measure the degree of association. Results: From 2019 to 2023, we recorded 353 Salmonella strains, of which 5% were found in blood, 37% in urine and 58% in stool. Patient age ranged from 1 to 86 years, with a mean of 27 ± 22.05 years and a mode of 5 years. Children aged 0 to 14 years (34%) and females (55.81%) predominated. The highest rate of contamination by Salmonella strains was 1.69% in 2022. The overall incidence of salmonellosis was 6.72 in 2019, 7.05 in 2020, 6.91 in 2021, 16.9 in 2022 and 6.26 in 2023 per 1000 samples. Resistance was 30.47% to β_lactam antibiotics, 24.22% to fluroquinolones and 37.97% to Salmonella spp. For Salmonella arizonae strains, resistance was 20.25% to aminoglycosides, 43.67% to chloramphenicol and 7.59% to imipenem. Conclusion: Laboratory-based surveillance of antibiotic resistance in Salmonella strains is needed in both human and veterinary medicine. Another study based on molecular characterization will identify new antibiotic-resistant variants circulating in CAR.展开更多

From the perspective of classification strength and correlation, three experiments are performed to investigate the potential application of random forest to traffic incident detection： comparison with a different number of decision trees; comparison with different decision trees; comparison with the neural network. The real traffic data of the 1-880 database is used in the experiments. The detection performance is evaluated by the common criteria including the detection rate, the false alarm rate, the mean time to detection, the classification rate and the area under the curve of the receiver operating characteristic （ROC）. The experimental results indicate that the model based on random forest can improve the decision rate, reduce the testing time, and obtain a higher classification rate. Meanwhile, it is competitive compared with multi-layer feed forward neural networks （MLF）.展开更多

Conventional ultrasonic cement bond logging uses vertical incidence and cannot accurately evaluate lightweight cement bonding. Oblique incidence is a new technology for evaluating cement quality with improved accuracy for lightweight cements. In this study, we simulated models of acoustic impedance of cement and cementing quality using ultrasonic oblique incidence, and we obtained the relation between cementing quality, acoustic impedance of cement, and the acoustic attenuation coeffi cient of the A0-mode and S0-mode Lamb waves. Then, we simulated models of different cement thickness and we obtained the relation between cement thickness and the time difference of the arrival between the A0 and A0′ modes.展开更多

The genetic algorithm is used to obtain the solutions to the rescue resources dispatching model. A case study shows that the proposed method can accurately reveal the impact of potential incidents on the costs of rescues according to the variations in the types and quantities of rescue resources and the optimal dispatching plan with respect to potential incidents can be obtained.The proposed method is applicable in real world scenarios.展开更多

The incident response framework based on rule-based reasoning, case-based reasoning and Bayesian networks reasoning is presented. First, a freeway incident management system （RK-IMS） based on rule-based reasoning is developed and applied for incident management in the northern section of the Nanjing-Lianyunguang Freeway. Then, field data from the two-year long operations of the RK-IMS are analyzed. Representations of incident case structures and Bayesian networks（BNs） structures related to incident responses are deduced. Finally, the k-nearest neighbor （k-NN） algorithm is applied to calculate the similarities of the cases. The preplan generation and the control strategy by integrating the k-NN algorithm are also developed. The model is validated by using incident data of the year 2006 from the RK-IMS. The comparison results indicate that the proposed algorithm is accurate and reliable.展开更多

In this paper, based on the statement of general concept and conventional calculation method of the poverty incidence, the calculation method of poverty incidence in the exit evaluation of poverty-stricken counties （also including poverty-stricken township and poverty-stricken villages） was investigated through the view of the third-party evaluation. In addition to considering the previous ＂number of planned poverty remaining population＂, the method also needed to give consideration to the exiting mistaken population, evaluation missing population. Based on the case in Yuanyang County, Honghe Hani and Yi Autonomous Prefecture, Yunnan Province, the poverty incidences of 10 exit planning villages by the end of 2017 in Yuanyang County were investigated and estimated, and suggestions were proposed to promote the precise poverty alleviation and poverty relief of the county.展开更多

The associations between variables and MIRs were analyzed by linear regression analyses and the 57 countries were selected according to their data quality. RESULTS The more developed regions showed high gastric cancer incidence and mortality crude rates, but lower MIR values than the less developed regions(0.64 vs 0.80, respectively). Among six continents, Oceania had the lowest(0.60) and Africa had the highest(0.91) MIR. A good WHO ranking and a high e/GDP were significantly associated with low MIRs(P = 0.001 and P = 0.001, respectively).CONCLUSION The MIR variation for gastric cancer would predict regional health disparities.展开更多

文摘To extend the traditional generalized grey incidence model, a novel grey incidence model based on inter- val grey numbers is constructed. Considering the numerical information of indexes cannot be accurately obtained and can be defined as interval grey numbers, the interval grey numbers are defined as standard interval grey num- bers which are split in white part and grey part. The absolute degree of incidence and relative degree of incidence based on the interval grey numbers are constructed and their arithmetic are given. Finally, an example about commercial aircraft index selection illuminates the effectiveness of the model. The results show that the model can sort indexes better and can extend the grey incidence models significantly.
文摘In April 2024,the International Agency for Research on Cancer(IARC)published the 2022 Global Cancer Statistics Report in CA:A Cancer Journal for Clinicians,focusing on the incidence of 36 kinds of cancers in 185 countries or regions around the world,different gender,geographical area and Human Development Index differences in different economic regions.Previously,China's National Cancer Center(NCC)collaborated with IARC to estimate China's cancer incidence data using actual and up-to-date surveillance data from China.This collaboration aimed to ensure consistency between the cancer burden data published by IARC and NCC.In February of the same year,the NCC released the latest estimated statistics regarding the cancer incidence in China for 2022 in the Journal of the National Cancer Center.This research seeks to gather and evaluate the latest reports on cancer incidence from both a global perspective and within China for the year 2022.By conducting a multi-dimensional analysis of cancer incidence patterns,gender distribution,geographic spread,and trends over time,the study highlights the distinctions in the burden of malignant tumors between China and the global scenario.Additionally,it explores the risk factors associated with high-incidence cancer types and examines the current status of prevention and control measures.The findings aim to serve as a valuable reference for developing effective cancer prevention and control strategies in China.
文摘BACKGROUND Pelvic fractures are often associated with significant morbidity,including injuries to the urinary tract.Understanding the incidence and risk factors for urinary tract injury in these patients is crucial for prompt diagnosis and management.This meta-analysis aims to synthesize existing evidence to determine the overall incidence and identify specific risk factors associated with urinary tract injuries in patients with pelvic fractures.AIM To determine the incidence and risk factors for urinary tract injuries in patients with pelvic fractures.METHODS A systematic search of PubMed,EMBASE,Scopus,and the Cochrane Library was conducted without date restrictions.Studies examining the incidence and risk factors of urinary tract injuries in patients with pelvic fractures were included.Data extracted included demographics,injury mechanism,pelvic fracture type,urinary tract injury incidence,mortality,and discharge disposition.Review Manager 5.4 was used for data analysis.RESULTS Ten studies comprising 22700 patients were included.The pooled incidence of urinary tract injury associated with pelvic fracture was 6.88%(95%CI:6.20%-7.55%).Vehicle,motorcycle,and pedestrian accidents were identified as risk factors for urinary tract injury,with relative risks(RR)of 1.08(95%CI:1.06-1.11),1.89(95%CI:1.78-2.00),and 1.53(95%CI:1.20-1.95),respectively.Pubic fracture and pelvic ring disruption were significantly associated with urinary tract injury[odds ratio(OR)1.94,95%CI:1.09-3.44 and OR 5.53,95%CI:4.67-6.54,respectively)].Patients without urinary tract injury were more likely to be discharged home(RR 0.79,95%CI:0.67-0.92).Mortality was higher in patients with urinary tract injury(OR 1.92,95%CI:1.77-2.09).CONCLUSION Urinary tract injury occurs in nearly 7%of patients with pelvic fractures.Motorcycle accidents,pubic fractures,and pelvic ring disruptions are significant risk factors.Urinary tract injury following pelvic fracture is associated with increased mortality.

文摘BACKGROUND Postoperative delirium(POD)is a concerning complication of organ transplantation.With organ transplantation offering hope to patients with end-stage organ disease,understanding the incidence and risk factors of POD is crucial,as it can significantly affect patients’prognosis and healthcare costs.AIM To systematically evaluate the incidence and risk factors of POD following organ transplantation to facilitate clinical prevention and optimize patient management and prognosis.METHODS Multiple databases such as PubMed and their reference lists were comprehensively searched using a combination of keywords related to organ transplantation and POD.Relevant observational studies on patients who had undergone solid organ transplantation and randomized controlled trials containing relevant analyses were included.Duplicated,data-deficient,non-English,and non-original data studies were excluded.Data were extracted independently by two researchers and then cross-checked.The Newcastle-Ottawa scale was used to evaluate the quality of the included studies.RevMan 5.3 was employed for data analysis.The pooled incidence of POD was calculated according to the data type,and the fixed or random effect model was employed to analyze risk factors based on heterogeneity.Subsequently,sensitivity analysis and publication bias assessments were performed.RESULTS A total of 39 relevant literatures were included.The overall incidence of POD in the organ transplant group was 20%[95%confidence interval(CI):18%-22%];liver transplant group,22%(95%CI:17%-26%);lung transplant group,34%(95%CI:23%-45%);and kidney transplant group,6%(95%CI:2%-10%).Primary graft dysfunction increased the POD risk,with a pooled odds ratio(OR)(95%CI)of 1.78(1.09-2.91).A history of hepatic encephalopathy increased the POD risk,with a pooled OR(95%CI)of 3.19(2.30-4.43).The higher the Acute Physiology and Chronic Health Evaluation II score,the greater the POD risk,with a pooled OR(95%CI)of 1.52(1.09-2.12).A history of alcohol abuse increased the POD risk,with a pooled OR(95%CI)of 2.84(1.74-4.65).Thus,the higher the model for end-stage liver disease score,the greater the POD risk,with a pooled OR(95%CI)of 2.49(1.14-5.43).POD was more likely to develop in patients with preoperative infections,with a pooled OR(95%CI)of 2.78(1.56-4.97).The use of diuretics increased the POD risk,with a pooled OR(95%CI)of 2.36(1.38-4.04).CONCLUSION In this study,the overall incidence of POD in patients who underwent organ transplantation is 20%.The incidence varies among different types of organ transplantation,and multiple factors can increase the POD risk.
文摘BACKGROUND Post-hepatectomy portal vein thrombosis(PH-PVT)is a life-threatening complication;however,the available literature on this topic is limited.AIM To examine the incidence,risk factors,and outcomes associated with PH-PVT.METHODS Medical records of patients who underwent hepatic resection for various diseases between February 2014 and December 2023 at Beijing Tsinghua Changgung Hospital affiliated with Tsinghua University(Beijing,China)were retrospectively reviewed.The patients were divided into a PH-PVT group and a non-PH-PVT group.Univariate and multivariate logistic regression analyses were performed to identify the risk factors for PH-PVT.RESULTS A total of 1064 patients were included in the study cohort,and the incidence and mortality rates of PH-PVT were 3.9%and 35.7%,respectively.The median time from hepatectomy to the diagnosis of PH-PVT was 6 days.Multivariate analysis revealed that hepatectomy combined with pancreaticoduodenectomy(HPD)[odds ratio(OR)=7.627(1.390-41.842),P=0.019],portal vein reconstruction[OR=6.119(2.636-14.203),P<0.001]and a postoperative portal vein angle<100°[OR=2.457(1.131-5.348),P=0.023]were independent risk factors for PH-PVT.Age≥60 years[OR=8.688(1.774-42.539),P=0.008]and portal vein reconstruction[OR=6.182(1.246-30.687),P=0.026]were independent risk factors for mortality in PH-PVT patients.CONCLUSION Portal vein reconstruction,a postoperative portal vein angle<100°and HPD were independent risk factors for PHPVT.Age≥60 years and portal vein reconstruction were independent risk factors for mortality in PH-PVT patients.
文摘Objective:Esophageal cancer has made a great contribution to the cancer burden in Jiangsu Province,East China.This study was aimed at reporting esophageal cancer incidence trend in 2009-2019 and its prediction to 2030.Methods:The burden of esophageal cancer in Jiangsu in 2019 was estimated using 54 cancer registries’data selected from Jiangsu Cancer Registry.Incident cases of 16 cancer registries were applied for the temporal trend from 2009 to 2019.The burden of esophageal cancer by 2030 was projected using the Bayesian age-period-cohort(BAPC)model.Results:About 24,886 new cases of esophageal cancer(17,233 males and 7,653 females)occurred in Jiangsu in 2019.Rural regions of Jiangsu had the highest incidence rate.The age-standardized incidence rate(ASIR,per 100,000 population)of esophageal cancer in Jiangsu decreased from 27.72 per 100,000 in 2009 to 14.18 per 100,000 in 2019.The BAPC model showed that the ASIR would decline from 13.01 per 100,000 in 2020 to 4.88 per 100,000 in 2030.Conclusions:According to the data,esophageal cancer incidence rates were predicted to decline until 2030,yet the disease burden is still significant in Jiangsu.The existing approaches to prevention and control are effective and need to be maintained.

文摘BACKGROUND: Severe acute pancreatitis(SAP) is commonly associated with acute organ failure, but its effects on cerebral function within intensive care unit(ICU) patients remains inadequately researched. This study aims to determine the prevalence of delirium in critically ill patients diagnosed with SAP, and to identify risk factors associated with delirium in this patient population.METHODS: This was a retrospective, multicenter study, which enrolled adult patients diagnosed with SAP who admitted intensive care unit(ICU) for at least 24 h. Patient assessment was conducted using the Richmond Agitation-Sedation Scale(RASS) and the Confusion Assessment Method for the ICU(CAM-ICU). The cumulative incidence of delirium was determined. Demographic, clinical data, and length of ICU stay were compared between patients with and without delirium. A logistic regression model was employed to identify potential risk factors for delirium. RESuLTS: A total of 1,814 patients were included from seven hospitals in Anhui province, China. Delirium was observed in 25.2% of patients. Logistic regression analysis identified APACHE II scores(odds ratio [OR]=3.37, 95% confidence interval [CI]: 1.09–10.43, P=0.04), physical restraint(OR=11.11, 95%CI: 4.35–28.39, P<0.05), invasive mechanical ventilation(IMV)(OR=2.44, 95%CI: 1.41–4.25, P=0.002), and ICU length of stay ≥ 7 days(OR=3.14, 95%CI: 2.27–4.36, P<0.05) as independent risk factors of delirium.cONcLuSION: The present study revealed a substantial incidence of delirium in critically ill patients with SAP, associated with factors including APACHE II score, IMV, physical restraint, and prolonged ICU stays.

文摘Background As the population in China rapidly ages,the prevalence of mild cognitive impairment(MCI)is increasing considerably.However,the causes of MCI vary.The continued lack of understanding of the various subtypes of MCI impedes the implementation of effective measures to reduce the risk of advancing to more severe cognitive diseases.Aims To estimate the prevalence and incidence rates of two MCI subtypes—amnestic MCI(aMCI)and vascular cognitive impairment without dementia(VCIND)—and to determine modifiable factors for them among older individuals in a multiregional Chinese cohort.Method This 1-year longitudinal study surveyed a random sample of participants aged≥60 years from a large,community-dwelling cohort in China.Baseline lifestyle data were self-reported,while vascular and comorbid conditions were obtained from medical records and physical examinations.In total,3514 and 2051 individuals completed the baseline and 1-year follow-up assessments,respectively.Logistic and linear regression analyses were used to identify the modifiable factors for MCI subtypes and predictors of cognitive decline,respectively.Results Among our participants,aMCI and VCIND demonstrated prevalence of 14.83%and 2.71%,respectively,and annual incidence(per 1000 person-years)of 69.6 and 10.6,respectively.The risk factor for aMCI was age,whereas its protective factors were high education level,tea consumption and physical activity.Moreover,VCIND risk factors were age,hypertension and depression.The presence of endocrine disease,cerebral trauma or hypertension was associated with a faster decline in cognition over 1 year.Conclusions MCI is a serious health problem in China that will only worsen as the population ages if no widespread interventions are implemented.Preventive strategies that promote brain activity and support healthy lifestyle choices are required.We identified modifiable factors for MCI in older individuals.The easy-to-adopt solutions such as tea consumption and physical activity can aid in preventing MCI.

文摘Background The Global Cancer Observatory(GLOBOCAN)2022 and the Global Burden of Disease(GBD)2021 are two primary databases for assessing the global cancer burden.This study aimed to compare the incidence and mortality rates of tracheal,bronchus,and lung(TBL)cancer reported in these databases and to analyze the observed discrepancies.Methods Age-standardized rates(ASRs),including age-standardized incidence rates and age-standardized mortality rates for TBL cancer,were obtained from GLOBOCAN 2022 and GBD 2021 for the most recent available year.Differences in ASRs at the national level between the two databases were quantified using pairwise differences,calculated as the absolute difference in ASRs divided by the mean of the ASRs from both sources.Correlations between macroeconomic factors and pairwise differences in ASRs were evaluated,and country features correlated with high pairwise differences were assessed.The data sources and methods used in the two databases were also compared.Results Strong correlations were identified between ASRs reported by GLOBOCAN 2022 and GBD 2021;however,significant differences were observed between estimates from the two data sources.African countries commonly exhibited larger pairwise differences in ASRs,whereas European countries demonstrated smaller pairwise differences in ASRs.Additionally,some populous developing countries,including China,South Africa,Brazil and India,showed smaller differences in ASRs.Countries lacking vital registration systems or high-quality population-based cancer registries displayed larger differences in ASRs.Furthermore,differences in ASRs were negatively correlated with macroeconomic factors.The data sources and estimation methods used by the two databases were inconsistent.Conclusions Discrepancies in TBL cancer incidence and mortality were observed between GLOBOCAN 2022 and GBD 2021.While differences in sources and methods partially explain these discrepancies,a country's cancer surveillance maturity and economic status also correlate with the accuracy of the estimates.Estimating the cancer burden in less wealthy countries remains a substantial challenge,necessitating long-term assistance and investment.
文摘Despite numerous research investigations to understand the influences of various structural parameters,to the authors'knowledge,no research has been the effect of different angles of incidence on stab response and performance of different types of protective textiles.Three distinct structures of 3D woven textiles and 2D plain weave fabric made with similar high-performance fiber and areal density were designed and manufactured to be tested.Two samples,one composed of a single and the other of 4-panel layers,from each fabric type structure,were prepared,and tested against stabbing at[0○],[22.5○],and[45○]angle of incidence.A new stabbing experimental setup that entertained testing of the specimens at various angles of incidence was engineered and utilized.The stabbing bench is also equipped with magnetic sensors and a UK Home Office Scientific Development Branch(HOSDB)/P1/B sharpness engineered knives to measure the impact velocity and exerted impact energy respectively.A silicon compound was utilized to imprint the Back Face Signature(BFS)on the backing material after every specimen test.Each silicon print was then scanned,digitized,and precisely measured to evaluate the stab response and performance of the specimen based on different performance variables,including Depth of Trauma(DOT),Depth of Penetration(DOP),and Length of Penetration(LOP).Besides,the post-impact surface failure modes of the fabrics were also measured using Image software and analyzed at the microscale level.The results show stab angle of incidence greatly influences the stab response and performance of protective textiles.The outcome of the study could provide not only valuable insights into understanding the stab response and capabilities of protective textiles under different angle of incidence,but also provide valuable information for protective textile manufacturer,armor developer and stab testing and standardizing organizations to consider the angle of incidence while developing,testing,optimizing,and using protective textiles in various applications.
文摘In sub-Saharan Africa, foodborne Salmonella infections cause around 680,000 deaths per year. The evolutionary aspects of the incidence of antibiotic resistance in Salmonella strains no longer seem to attract much interest in the Central African Republic (CAR), although salmonellosis remains a health problem requiring national and international surveillance. Methodology: The study conducted at the National Laboratory of Clinical Biology and Public Health, Bangui, Central African Republic (LNBCSP) was a retrospective descriptive study. The study duration was five years (January 2019 to December 2023). The study sample consisted of patients who underwent bacteriological testing of stool, blood and urine samples for Salmonella at the LNBCSP in Bangui during this period. Study variables were age, sex, year and bacteriological test results. Statistical tests were used to compare incidences. Relative risks (RR) were calculated to measure the degree of association. Results: From 2019 to 2023, we recorded 353 Salmonella strains, of which 5% were found in blood, 37% in urine and 58% in stool. Patient age ranged from 1 to 86 years, with a mean of 27 ± 22.05 years and a mode of 5 years. Children aged 0 to 14 years (34%) and females (55.81%) predominated. The highest rate of contamination by Salmonella strains was 1.69% in 2022. The overall incidence of salmonellosis was 6.72 in 2019, 7.05 in 2020, 6.91 in 2021, 16.9 in 2022 and 6.26 in 2023 per 1000 samples. Resistance was 30.47% to β_lactam antibiotics, 24.22% to fluroquinolones and 37.97% to Salmonella spp. For Salmonella arizonae strains, resistance was 20.25% to aminoglycosides, 43.67% to chloramphenicol and 7.59% to imipenem. Conclusion: Laboratory-based surveillance of antibiotic resistance in Salmonella strains is needed in both human and veterinary medicine. Another study based on molecular characterization will identify new antibiotic-resistant variants circulating in CAR.

文摘In order to avoid the noise and over fitting and further improve the limited classification performance of the real decision tree, a traffic incident detection method based on the random forest algorithm is presented. From the perspective of classification strength and correlation, three experiments are performed to investigate the potential application of random forest to traffic incident detection： comparison with a different number of decision trees; comparison with different decision trees; comparison with the neural network. The real traffic data of the 1-880 database is used in the experiments. The detection performance is evaluated by the common criteria including the detection rate, the false alarm rate, the mean time to detection, the classification rate and the area under the curve of the receiver operating characteristic （ROC）. The experimental results indicate that the model based on random forest can improve the decision rate, reduce the testing time, and obtain a higher classification rate. Meanwhile, it is competitive compared with multi-layer feed forward neural networks （MLF）.

文摘Ultrasonic cement bond logging is a widely used method for evaluating cementing quality. Conventional ultrasonic cement bond logging uses vertical incidence and cannot accurately evaluate lightweight cement bonding. Oblique incidence is a new technology for evaluating cement quality with improved accuracy for lightweight cements. In this study, we simulated models of acoustic impedance of cement and cementing quality using ultrasonic oblique incidence, and we obtained the relation between cementing quality, acoustic impedance of cement, and the acoustic attenuation coeffi cient of the A0-mode and S0-mode Lamb waves. Then, we simulated models of different cement thickness and we obtained the relation between cement thickness and the time difference of the arrival between the A0 and A0′ modes.

文摘An optimal resource dispatching method is proposed to solve the multiple-response problem under the conditions of potential incidents on freeway networks.Travel time of the response vehicle is selected instead of route distance as the weight to reflect the impact of traffic conditions on the decisions of rescue resources.According to the characteristics of different types of rescue vehicles the dispatching decision-making time is revised to show the heterogeneity among different rescue vehicle dispatching modes. The genetic algorithm is used to obtain the solutions to the rescue resources dispatching model. A case study shows that the proposed method can accurately reveal the impact of potential incidents on the costs of rescues according to the variations in the types and quantities of rescue resources and the optimal dispatching plan with respect to potential incidents can be obtained.The proposed method is applicable in real world scenarios.

文摘The artificial intelligence technique is used to generate a freeway incident response plan. The incident response framework based on rule-based reasoning, case-based reasoning and Bayesian networks reasoning is presented. First, a freeway incident management system （RK-IMS） based on rule-based reasoning is developed and applied for incident management in the northern section of the Nanjing-Lianyunguang Freeway. Then, field data from the two-year long operations of the RK-IMS are analyzed. Representations of incident case structures and Bayesian networks（BNs） structures related to incident responses are deduced. Finally, the k-nearest neighbor （k-NN） algorithm is applied to calculate the similarities of the cases. The preplan generation and the control strategy by integrating the k-NN algorithm are also developed. The model is validated by using incident data of the year 2006 from the RK-IMS. The comparison results indicate that the proposed algorithm is accurate and reliable.
文摘Poverty incidence is the key index that needs to be measured in the poverty exit examination and evaluation of 832 poverty-stricken counties and 128 000 poverty-stricken villages. In this paper, based on the statement of general concept and conventional calculation method of the poverty incidence, the calculation method of poverty incidence in the exit evaluation of poverty-stricken counties （also including poverty-stricken township and poverty-stricken villages） was investigated through the view of the third-party evaluation. In addition to considering the previous ＂number of planned poverty remaining population＂, the method also needed to give consideration to the exiting mistaken population, evaluation missing population. Based on the case in Yuanyang County, Honghe Hani and Yi Autonomous Prefecture, Yunnan Province, the poverty incidences of 10 exit planning villages by the end of 2017 in Yuanyang County were investigated and estimated, and suggestions were proposed to promote the precise poverty alleviation and poverty relief of the county.
文摘AIM To evaluate the association between mortality-to-incidence ratios(MIRs) and health disparities.METHODS In this study, we used the GLOBOCAN 2012 database to obtain the cancer incidence and mortality data for 57 countries, and combined this information with the World Health Organization(WHO) rankings and total expenditures on health/gross domestic product(e/GDP). The associations between variables and MIRs were analyzed by linear regression analyses and the 57 countries were selected according to their data quality. RESULTS The more developed regions showed high gastric cancer incidence and mortality crude rates, but lower MIR values than the less developed regions(0.64 vs 0.80, respectively). Among six continents, Oceania had the lowest(0.60) and Africa had the highest(0.91) MIR. A good WHO ranking and a high e/GDP were significantly associated with low MIRs(P = 0.001 and P = 0.001, respectively).CONCLUSION The MIR variation for gastric cancer would predict regional health disparities.
