Pseudo-Semi-Overlap Functions-Based Fuzzy Rough Sets Applied to Image Edge Extraction

As an extension of overlap functions, pseudo-semi-overlap functions are a crucial class of aggregation functions. Therefore, (I, PSO)-fuzzy rough sets are introduced, utilizing pseudo-semi-overlap functions, and further extended for applications in image edge extraction. Firstly, a new clustering function, the pseudo-semi-overlap function, is introduced by eliminating the symmetry and right continuity present in the overlap function. The relaxed nature of this function enhances its applicability in image edge extraction. Secondly, the definitions of (I, PSO)-fuzzy rough sets are provided, using (I, PSO)-fuzzy rough sets, a pair of new fuzzy mathematical morphological operators (IPSOFMM operators) is proposed. Finally, by combining the fuzzy C-means algorithm and IPSOFMM operators, a novel image edge extraction algorithm (FCM-IPSO algorithm) is proposed and implemented. Compared to existing algorithms, the FCM-IPSO algorithm exhibits more image edges and a 73.81% decrease in the noise introduction rate. The outstanding performance of (I, PSO)-fuzzy rough sets in image edge extraction demonstrates their practical application value.

On Multiplicative Generators of n-Dimensional Overlap Functions

In this paper, inspired by the multiplicative generators of overlap functions, we mainly propose the concepts of multiplicative generator pairs of n-dimensional overlap functions, in order to extend the dimensionality of overlap functions from 2 to n. We present the condition under which the pair (g, h) can multiplicatively generate an n-dimensional overlap function Og,h. we focus on the homogeneity and idempotency property on multiplicatively generated n-dimensional overlap functions.

Management of Overlap Syndrome between Functional Dyspepsia and Irritable Bowel Syndrome by Western and Traditional Chinese Medicine

The overlap syndrome of functional dyspepsia and irritable bowel syndrome (FD-IBS) is very common and difficult to treat. There are many risk factors of FD-IBS. Mental illness of FD-IBS patients is more serious. Functional dyspepsia and irritable bowel syndrome have some similarities in the aspects of pathophysiology, pathogenesis, and treatment. We should pay attention to two aspects of the treatment of overlap syndrome, one is simplifying medications, the other is using gastrointestinal motility drug with bidirectional regulative function when necessary. Traditional Chinese medicine in this respect shows some advantages. This review addresses the epidemiology, risk factors, clinical features, pathogenesis and management of FD-IBS.

The Additive Generators of <i>n</i>-Dimensional Overlap Functions

Constructions of <i>n</i>-Dimensional Overlap Functions Based on Bivariate Overlap Functions

In this paper, we firstly introduce some new results on overlap functions and n-dimensional overlap functions. On the other hand, in a previous study, Gómez et al. presented some open problems. One of these open problems is “to search the construction of n-dimensional overlapping functions based on bi-dimensional overlapping functions”. To answer this open problem, in this paper, we mainly introduce one construction method of n-dimensional overlap functions based on bivariate overlap functions. We mainly use the conjunction operator ∧ to construct n-dimensional overlap functions based on bivariate overlap functions and study their basic properties.

Feasibility of Tiotropium Bromide Treatment in Patients with Asthma-COPD Overlap Syndrome and its Effect on Lung Function

Objective:To explore the feasibility of tiotropium bromide therapy and its effect on the lung function of patients with asthma-COPD overlap syndrome(ACOS).Method:The 58 subjects selected in this study were all ACOS patients admitted to our hospital(Hohhot First Hospital)from October 2020 to October 2022.They were grouped according to the random number table method and divided into a control group(29 cases)and an observation group(29 cases).The control group received routine treatment plus salmeterol-fluticasone powder inhalation treatment,and the observation group received tiotropium bromide treatment.The relevant indicators of the two groups were compared.Results:The total clinical effective rate of the observation group was significantly higher than that of the control group.Besides,the forced vital capacity(FVC),forced expiratory volume in 1 second(FEV1)levels,and ACT scores of the two groups increased after treatment,with the observation group having better results than the control group.The residual volume-total lung capacity ratio(RV/TLC),acute exacerbation frequency,and CAT scores all decreased,with the observation group showing smaller values than the control group.The difference between the results of both groups were significant(P<0.05)Conclusion:Tiotropium bromide has a significant clinical effect in the treatment of ACOS patients and can effectively improve the lung function of patients.

A New Method to Resolve Overlapped Voltammetric Peaks

A new method called spline convolution (SC) for resolving overlapped peaks was proposed in this paper. The differential pulse voltammetric overlapped peaks of mixtures of Pb(II) and Tl(I) were investigated by this method, and satisfactory results were obtained. The results show excellent correlation between peak areas of the processed signals and the concentrations.

Functional composition of tall-statured trees underpins aboveground biomass in tropical forests

The influences of trait diversity(i.e.,the niche complementarity effect)and functional composition(i.e.,the mass ratio effect)on aboveground biomass(AGB)is a highly debated topic in forest ecology.Therefore,further studies are needed to explore these mechanisms in unstudied forest ecosystems to enhance our understanding,and to provide guidelines for specific forest management.Here,we hypothesized that functional composition would drive AGB better than trait diversity and stem size inequality in the(sub-)tropical forests of Nepal.Using data from 101 forest plots,we tested 25 structural equation models(SEMs)to link elevation,stem DBH inequality,trait diversity(i.e.,trait richness,evenness,dispersion and divergence),functional composition[i.e.,community-weighted of maximum height mean(CWM of Hmax),specific leaf area(CWM of SLA),leaf dry matter content(CWM of LDMC),and wood density(CWM of WD)]and AGB.The best-fitted SEMs indicated that CWM of Hmax promoted AGB while overruling the impacts of trait diversity indices on AGB.However,low trait diversity indices were linked with higher AGB while overruling the effects of CWM of SLA,LDMC and WD on AGB.In addition,AGB decreased with increasing elevation,whereas stem size inequality did not influence AGB.Our results suggest that divergent species’functional strategies could shape AGB along an altitudinal gradient in tropical forests.We argue that forest management practices should include plant functional traits in the management plan for the co-benefits of biodiversity conservation and carbon sequestration that underpins human wellbeing.

Stability and stabilization of discrete T-S fuzzy time-delay system based on maximal overlapped-rules group

The problems of stability and stabilization for the discrete Takagi-Sugeno（T-S） fuzzy time-delay system are investigated.By constructing a discrete piecewise Lyapunov-Krasovskii function（PLKF） in each maximal overlapped-rules group（MORG）,a new sufficient stability condition for the open-loop discrete T-S fuzzy time-delay system is proposed and proved.Then the systematic design of the fuzzy controller is investigated via the parallel distributed compensation control scheme,and a new stabilization condition for the closed-loop discrete T-S fuzzy time-delay system is proposed.The above two sufficient conditions only require finding common matrices in each MORG.Compared with the common Lyapunov-Krasovskii function（CLKF） approach and the fuzzy Lyapunov-Krasovskii function（FLKF） approach,these proposed sufficient conditions can not only overcome the defect of finding common matrices in the whole feasible region but also largely reduce the number of linear matrix inequalities to be solved.Finally,simulation examples show that the proposed PLKF approach is effective.

Separating Overlapped Peaks of SF6 Decomposed Products Based on Iterative Curve-fitting Method

The SF6 decomposed products are very alike,so the peaks of the SF6 decomposed products are overlapped.It make us hard to quantitatively calculate.This paper introduced a method to separate the overlapped chromatogram peaks with iterative curve-fitting and Gauss function,and deduced the formula of the iterative curve-fitting;provided a method to calculate the initial value of the peaks intensity and width by iterative formula,and confirm the final peaks intensity and width to separate the overlapped signals.By the analysis of the real chromatogram data,it proved the validity of this method on the main components used in distinguishing the GIS internal defects.This method overcomes the influence of SF6 peak to the other thin concentration peaks,so it can be used in the study of the quantitative analysis of the decomposed products on different failures and different voltages.

运用“形神同调”理论探析功能性胃肠病症状重叠的诊治思路与方法

功能性胃肠病(functional gastrointestinal disorders,FGIDs)症状重叠现象在临床上非常普遍,其发生机制与“脑-肠互动障碍”密切相关,这与中医“形神失和”理论核心的内涵高度契合。“形神合一”作为中医整体观念的重要组成部分,认为形为神之舍,神依附形而存在,二者具有相互为用的特点。FGIDs病机以脾胃功能失调、神明失用为主。治疗方面当以形神同调为基本原则,辨证选方用药,为FGIDs症状重叠患者的临床诊疗提供了新思路。

中亚热带喀斯特森林树木功能型的生态位特征

【目的】分析中亚热带喀斯特森林树木功能型的生态位特征,推断不同功能型树木对资源的利用程度和种间竞争差异,为喀斯特地区的植被恢复与重建提供理论指导。【方法】以中亚热带喀斯特常绿落叶阔叶混交林为研究对象,在样地调查基础上根据冠层高度、种群大小、耐荫性和种子传播方式将被选的40种树木划分为不同功能型,通过计测生态位宽度和生态位重叠指数分析不同功能型树木的生态位特征。【结果】喀斯特森林树木的生态位宽度普遍较低,表现为常见种>偶见种>稀有种,且三者的生态位宽度间差异显著;重力传播种的生态位宽度显著低于动物和风力传播种,不同耐荫性和冠层高度功能型间的生态位宽度无显著差异;40种树木种对间的生态位重叠指数同样较低,常见种的生态位重叠指数显著高于偶见种和稀有种,上层种显著高于下层种,喜光种显著高于耐荫种,而重力传播种则显著低于动物和风力传播种;常见种与偶见种间的生态位重叠指数显著高于常见种与稀有种以及偶见种与稀有种间,动物与风力传播种间的生态位重叠指数显著高于动物与重力种间以及风力与重力种间,而中生与耐荫种间的生态位重叠指数则显著低于喜光与中生种以及喜光与耐荫种间。【结论】中亚热带喀斯特常绿落叶阔叶混交林中多数树种占据较小的生态位空间并可能存在较低的种间竞争作用,不同树木功能型生态位宽度和生态位重叠指数的差异可能与生境异质性和物种性状差异等存在密切联系。在进行退化生境植被重建时,可根据不同功能型树木的生态位特征合理构建群落的组成与结构,促进森林植被快速恢复。
