Specifically, we shall contrast the lexical causatives in English, Japanese and Chinese. We adopt Pylkk^inen＇s （2008） minimalist model as the framework. According to this model, the similarity of cross-linguistic causatives is attributed to the presence of the functional head vCAUSE. Variations of causatives in different languages can be attributed to two parameters： （i） whether vCAUSE obligatorily requires the presence of an external argument or not; （ii） the complement of vCAUSE is root-selecting, verb-selecting or phase-selecting. Causatives in languages can be ronghly divided into two types, namely the lexical causatives and the productive ones. As far as lexical causatives are concerned, languages can be classified into Voice-bundling vs. Non-Voice-bundling ones according to whether the presence of an external argument （i.e, causer or cause） is obligatorily required in lexical causatives or not. English is Voice-bundling and Japanese is Non-Voice-bundling. Chinese stands as the third type of languages which may be called semi-Voice-bnndling language since lexical unaccusative causatives in Chinese are Non-Voice-bundling while action-result-compounds unaccusatives （resultative unaccusatives） are Voice-bundling. Causative heads of lexical cat, satires in these three languages are all root-selecting.展开更多

Causative verbs in MA are characterized by the systematic gemination of their medial consonants. However, it is not easy to determine the morphological nature of the causative morpheme involved in this derivation. Also, it is not clearly known why the causative morpheme gets realized exactly on the second segment of the base form.Therefore, we seek to achieve the following goals. First, we intend to determine the nature of the causative morpheme. Second, we aim to explain why the causative morpheme is realized on the second segment of the base form. In this respect, we show that the causative morpheme is represented by a featureless consonantal mora that targets the second segment of the base root, turning it into a geminate. We also show that the causative morpheme gets infixed thanks to the privileged status of root-initial segments.展开更多

Objectives: Our study aims to present the results of an analysis of reviews of maternal deaths at HGOPY. Methodology: This was a descriptive cross-sectional study with retrospective data collection from archived records and reviewed maternal death reports. Our study lasted 8 months, from October 1, 2023 to May 31, 2024. The study covered maternal death files at the HGOPY over an 8-year period, from 1st of January 2016 to the 31st of December 2023. Data were processed and analyzed using Statitical Paquage for Social Science (SPSS) version 26.0. Results: We counted a total of 160 maternal deaths, of which 97 had been reviewed. We excluded 61 deceased women reviewed and retained 33. We recorded a cumulative total of 160 maternal deaths and 19,651 live births. The peak in the proportion of maternal deaths at the Yaoundé Gynaeco-Obstetric and Paediatric Hospital was in 2021, with a proportion of 0.013. No maternal deaths had been reviewed between 2016 to 2017. Most deaths (64%) occurred between 37 and 40 weeks. The majority (30.5%) were aged between 30 and 35. The data show that 80.6% of maternal deaths were due to direct obstetric causes, while 19.4% were due to indirect causes. Most deaths (69.4%) were preventable. Only 8.3% were not preventable. Conclusion: Concerted efforts must be made to adapt maternal death prevention and management strategies to local contexts in order to significantly reduce these alarming figures.展开更多

Traditional methods, which typically rely on the entire time series and overlook critical local features, can lead to biased inferences about causal relationships, thus hindering the accurate identification of root cause variables. This study proposed a shapelet-based state evolution graph for fault root cause diagnosis (SEG-RCD), which enables causal inference through the analysis of the important local features. First, the regularized autoencoder and fault contribution plot are used to identify the fault onset time and candidate root cause variables, respectively. Then, the most representative shapelets were extracted to construct a state evolution graph. Finally, the propagation path was extracted based on fault unit shapelets to pinpoint the fault root cause variable. The SEG-RCD can reduce the interference of noncausal information, enhancing the accuracy and interpretability of fault root cause diagnosis. The superiority of the proposed SEG-RCD was verified through experiments on a simulated penicillin fermentation process and an actual one.展开更多

文摘Echinococcus is a zoonotic parasite and 1 of 17 neglected tropical diseases with a worldwide distribution.The World Health Organization(WHO)targeted for control or elimination by 2050[1,2].Two main species of Echinococcus infect humans:Echinococcus granulosus,causing cystic echinococcosis(CE),and Echinococcus multilocularis(EM),causing alveolar echinococcosis(AE)[3].AE is much rarer but far more severe than CE and ranks as one of the most dangerous helminthic zoonoses in the world[4,5].Humans are rare aberrant intermediate hosts and typically become infected through the ingestion of EM eggs shed in the feces of definitive hosts[6].After an incubation period of many years,humans may develop AE[7].While slow-growing,AE is a devastating clinical condition characterized by silent progression and infiltrative proliferation of the parasite,mimicking a malignancy[7].Without appropriate treatment,AE has a death rate of more than 90%within 10 years of diagnosis[5].For this reason,AE must be considered in the differential diagnosis of patients presenting with a hepatic mass or malignancy.

文摘Understanding the levels,causes,and sources of fluoride in groundwater is critical for public health,effective water resource management,and sustainable utilization.This study employs multivariate statistical methods,hazard quotient assessment,and geochemical analyses,such as mineral saturation index,ionic activities,and Gibbs diagrams,to investigate the hydrochemical characteristics,causes,and noncarcinogenic risks of fluoride in Red bed groundwater and geothermal water in the Guang'an area and neighboring regions.Approximately 9%of the Red bed groundwater samples contain fluoride concentrations exceeding 1 mg·L^(-1).The predominant water types identified are Cl-Na and HCO_(3)-Na,primarily influenced by evapotranspiration.Low-fluoride groundwater and high-fluoride geothermal water exhibit distinct hydrochemical types HCO_(3)-Ca and SO_(4)-Ca,respectively,which are mainly related to the weathering of carbonate,sulfate,and fluorite-containing rocks.Correlation analysis reveals that fluoride content in Red bed groundwater is positively associated with Na^(+),Cl^(-),SO_(4)^(2-),and TDS(r^(2)=0.45-0.64,p<0.01),while in geothermal water,it correlates strongly with pH,K^(+),Ca^(2+),and Mg^(2+)(r^(2)=0.52-0.80,p<0.05).Mineral saturation indices and ionic activities indicate that ion exchange processes and the dissolution of minerals such as carbonatite and fluorite are important sources of fluoride in groundwater.The enrichment of fluorine in the Red bed groundwater is linked to evaporation,cation exchange and dissolution of fluorite,caused by the lithologic characteristics of the red bed in this area.However,it exhibits minimal correlation with the geothermal water in the adjacent area.The noncarcinogenic health risk assessment indicates that 7%(n=5)of Red bed groundwater points exceed the fluoride safety limit for adults,while 12%(n=8)exceed the limit for children.These findings underscore the importance of avoiding highly fluoridated red bed groundwater as a direct drinking source and enhancing groundwater monitoring to mitigate health risks associated with elevated fluoride levels.

文摘OBJECTIVE To investigate possible associations between physical function assessment scales,such as Short Physical Performance Battery(SPPB)and Berg Balance Scale(BBS),with all-cause mortality in acute decompensated heart failure(ADHF)patients.METHODS A total of 108 ADHF patients were analyzed from October 2020 to October 2022,and followed up to May 2023.The association between baseline clinical characteristics and all-cause mortality was analyzed by univariate Cox regression analysis,while for SPPB and BBS,univariate Cox regression analysis was followed by receiver operating characteristic curves,in which the area under the curve represented their predictive accuracy for all-cause mortality.Incremental predictive values for both physical function assessments were measured by calculating net reclassification index and integrated discrimination improvement scores.Optimal cutoff value for BBS was then identified using restricted cubic spline plots,and survival differences below and above that cut-off were compared using Kaplan-Meier survival curves and the log-rank test.The clinical utility of BBS was measured using decision curve analysis.RESULTS For baseline characteristics,age,female,blood urea nitrogen,as well as statins,angiotensin-converting enzyme inhibitors,angiotensin II receptor blockers,or angiotensin receptor-neprilysin inhibitors,were predictive for all-cause mortality for ADHF patients.With respect to SPPB and BBS,higher scores were associated with lower all-cause mortality rates for both assessments;similar area under the curves were measured for both(0.774 for SPPB and 0.776 for BBS).Furthermore,BBS≤36.5 was associated with significantly higher mortality,which was still applicable even adjusting for confounding factors;BBS was also found to have great clinical utility under decision curve analysis.CONCLUSIONS BBS or SPPB could be used as tools to assess physical function in ageing ADHF patients,as well as prognosticate on all-cause mortality.Moreover,prioritizing the improvement of balance capabilities of ADHF patients in cardiac rehabilitation regimens could aid in lowering mortality risk.
文摘Background: Maternal mortality remains a major public health problem worldwide. Objectives: Our study aims to present the results of an analysis of reviews of maternal deaths at HGOPY. Methodology: This was a descriptive cross-sectional study with retrospective data collection from archived records and reviewed maternal death reports. Our study lasted 8 months, from October 1, 2023 to May 31, 2024. The study covered maternal death files at the HGOPY over an 8-year period, from 1st of January 2016 to the 31st of December 2023. Data were processed and analyzed using Statitical Paquage for Social Science (SPSS) version 26.0. Results: We counted a total of 160 maternal deaths, of which 97 had been reviewed. We excluded 61 deceased women reviewed and retained 33. We recorded a cumulative total of 160 maternal deaths and 19,651 live births. The peak in the proportion of maternal deaths at the Yaoundé Gynaeco-Obstetric and Paediatric Hospital was in 2021, with a proportion of 0.013. No maternal deaths had been reviewed between 2016 to 2017. Most deaths (64%) occurred between 37 and 40 weeks. The majority (30.5%) were aged between 30 and 35. The data show that 80.6% of maternal deaths were due to direct obstetric causes, while 19.4% were due to indirect causes. Most deaths (69.4%) were preventable. Only 8.3% were not preventable. Conclusion: Concerted efforts must be made to adapt maternal death prevention and management strategies to local contexts in order to significantly reduce these alarming figures.
文摘The increasing cost of infrastructure development risks stifling national investment plans.Many projects in Uganda have suffered because of the frequency and magnitude of claims made by parties involved especially the contractors.As a result,the construction industry is plagued with claims which quite often lead to adversarial relationships.The major grounds for claims were identified through studying the contract documents where claims had been made.Increase in scope;change orders;errors in contract documents;inclement weather;inflation;delay in possessing the site;and change in the tax policy were the most prevalent grounds for making claims.Problems identified in claiming process include delays in getting approval;information on claims not reliable;hostility from the parties involved;pricing of claims;delays in effecting payment when approved;and overzealous contract interpretation leading to misunderstanding and delays Using a survey on project managers for 64 contractors and their corresponding clients or their representatives,the major ways in which it can be reduced were identified as being thoroughness during the design phase;providing for inflation;proper planning of works;using prequalified contractors;and proper documentation of records.Clients have a big role to play in reducing claims.

文摘BACKGROUND Mediastinal lymph nodes(MLNs)can be enlarged due to various benign or malignant causes.Endoscopic ultrasound(EUS)is often employed for the acquisition of tissue specimens of the enlarged MLN(EMLN).AIM To determine the causes,document the symptoms,and determine factors predicting good yield of EUS-guided EMLN biopsy.METHODS All patients having EMLN(>10 mm)on thoracic imaging and referred for EUSguided biopsy were included in this retrospective observational study.Adequacy of the tissue specimen was assessed by the endoscopist with macroscopic on-site evaluation(MOSE)and then sent to a histopathologist for final diagnosis.Analysis for factors predicting good biopsy yield was then performed.RESULTS Of the total 243 patients with EMLN,131(53.9%)were males.The mean age was 47.6(±14.7)and range 14-86 years.Commonest causes of EMLN were tuberculosis 82(33.7%),anthracosis 53(21.8%),neoplastic disease 43(17.7%)and sarcoidosis 14(5.8%).Among the 43 patients with neoplastic diseases:40 had metastatic disease(breast 9,lung 7,pancreatobiliary 6,esophagus 5,kidney 5,hepatocellular 2,neuroendocrine 2,gastrointestinal stromal 1,undetermined 3)and 3 had primary malignancies(lymphoproliferative disorder 2,Kaposi sarcoma 1).Chest related clinical symptoms were absent in more than half the patients with tuberculosis 51/82(62.2%),anthracosis 31/53(58.5%)and neoplastic disease 28/43(65.1%).Factors associated with good biopsy yield were:Subcarinal location of MLN(P=0.026),MLN size>12 mm(P<0.0001),use of fine-needle biopsy(vs fine-needle aspiration)(P=0.049)and satisfactory MOSE(P<0.0001)on univariate analysis;while MLN size>12 mm(P=0.005)and satisfactory MOSE(P<0.0001)on multivariate analysis.CONCLUSION Tuberculosis,anthracosis and metastatic disease were the commonest causes of EMLN.More than half the cases with EMLN had no chest-related symptoms.Large MLN size and satisfactory MOSE observation predicted a good biopsy yield.

文摘Background Physical frailty and depression may share common pathophysiological pathways associated with dementia and thus interact with each other.However,previous studies have primarily focused on the individual impact of these factors on dementia.Aims To examine the joint effect and interaction of physical frailty and depression on the risk of all-cause dementia.Methods We conducted prospective analyses among participants aged≥60 years from three cohorts:the UK Biobank(UKB),the English Longitudinal Study of Ageing(ELSA)and the Health and Retirement Study(HRS).Physical frailty was assessed using modified versions of the Fried frailty phenotype.Depression was evaluated through mental health questionnaires or combined with hospital admission records.The primary outcome was incident all-cause dementia,identified via active follow-up and passive surveillance.Cox proportional hazards models were used to estimate the hazard ratios(HRs)and 95%confidence intervals(CIs).Results A total of 220947 participants(mean age:64.5 years;53.3%female)were included.Over 2832696 person-years of follow-up,9088 participants(7605 in UKB,1207 in HRS and 276 in ELSA)developed incident all-cause dementia.Compared with robust individuals,frail participants faced a 155%increased risk of dementia(pooled HR:2.55,95%CI 2.36 to 2.76;I2=72.3%).Depression conferred a 1.59-fold excess risk for dementia(pooled HR:1.59,95%CI 1.50 to 1.69;I2=56.8%).Adding physical frailty and depression to a traditional dementia risk model significantly improved prediction accuracy(all p-Δarea under the curve<0.05).Jointly,participants with both physical frailty and depression exhibited the highest dementia risk(pooled HR:3.23,95%CI 2.86 to 3.65;I2=41.6%)compared with those without physical frailty and depression.Moreover,a significant additive interaction between physical frailty and depression was observed(pooled relative excess risk due to interaction:0.38,95%CI 0.13 to 0.63),with 17.1%(95%CI 6.0%to 28.3%)of dementia risk attributed to their interactive effects.Conclusions Individuals with both physical frailty and depression had the highest risk of dementia.More importantly,these two factors interact in an additive manner,further amplifying dementia risk.

文摘Accurate fault root cause diagnosis is essential for ensuring stable industrial production. Traditional methods, which typically rely on the entire time series and overlook critical local features, can lead to biased inferences about causal relationships, thus hindering the accurate identification of root cause variables. This study proposed a shapelet-based state evolution graph for fault root cause diagnosis (SEG-RCD), which enables causal inference through the analysis of the important local features. First, the regularized autoencoder and fault contribution plot are used to identify the fault onset time and candidate root cause variables, respectively. Then, the most representative shapelets were extracted to construct a state evolution graph. Finally, the propagation path was extracted based on fault unit shapelets to pinpoint the fault root cause variable. The SEG-RCD can reduce the interference of noncausal information, enhancing the accuracy and interpretability of fault root cause diagnosis. The superiority of the proposed SEG-RCD was verified through experiments on a simulated penicillin fermentation process and an actual one.
