Embryonic numerical and structural chromosomal abnormalities are the most common cause of early pregnancy loss. However, role submicroscopic copy-number variations (CNVs) in loss is unclear, little known about critical regions candidate genes for miscarriage, because large size abnormalities. The aim this study was to identify potential miscarriage-associated CNVs as well miscarriage.Over a 5-year period, 5180 fresh miscarriage specimens were investigated using quantitative fluorescent...
Purpose The damping accumulated discrete MGM(1, m) power model is proposed for the problem of forecasting share agricultural output value and employment in China. Design/methodology/approach In this study, was developed based on idea modelling by introducing a generating operator index. new can better identify non-linear characteristics existing between different factors multivariate system accurately describe forecast trend changes data series each them. Findings validity rationality are...
Purpose Electricity plays an important role in the economic condition of any country. Nowadays, Pakistan is badly affected by shortage electricity, which directly growth state. The purpose this study to propose improved grey model DGPM(1,1,N) forecast Pakistan's production installed capacity and consumption. Design/methodology/approach To significantly simulate predict accuracy, discrete polynomial with new information priority accumulation. particle swarm optimization (PSO) algorithm used...
Purpose The purpose of this study is to propose an unbiased generalized grey relational closeness evaluation model improve the accuracy regional agricultural drought vulnerability decision-making results, as well provide theoretical support for reducing risk and losses. Design/methodology/approach index weight calculated using a rough set deviation minimization criterion, degree between research object double reference sequence thoroughly investigated degree. Because different rankings can...
Abstract Drought is one of the major natural disasters in world, and it important to understand grasp spatiotemporal evolution characteristics drought for monitoring prevention. In this study, standardized precipitation evapotranspiration index (SPEI) was calculated based on monthly average temperature data from 15 meteorological stations Henan Province, China during period 1987–2020. The droughts Province were analyzed using run theory Moran's I, prediction carried out grey disaster theory....
Purpose The purpose of this paper is to research the status quo and future trend income elasticity consumer demand Chinese rural residents. Design/methodology/approach uses Model ELES GM(1,1) analyze predict in areas China. Findings findings show indicator that China quite large at present, but most sub‐categories indicators a declining future. Practical implications includes for relevant departments adjust economic polices timely reasonably, according specific form based on above....
Purpose The purpose of this paper is to establish a two-stage grey cloud clustering model assess the drought risk level 18 prefecture-level cities in Henan Province. Design/methodology/approach process divided into two stages. In first stage, coefficient vectors are obtained by clustering. second with help weight kernel function, general representation vector group given. And new that integrates support factors adjacent components was stage. entropy resolution set as demarcation line stages,...
Purpose According to the basic principle of grey system and third axiom buffer operator, aiming at problem disturbance, some new weakening operators are established by analytical skills in process prediction. The contradictions between quantitative analysis qualitative existing pretreatment for vibration data sequences is resolved effectively. An example shows that kind increase forecast precision model remarkably. aim this paper attempt resolve sequences. Design/methodology/approach In view...
Purpose Hazard assessment on drought disaster is of great significance for improving risk management. Due to the complexity and uncertainty disaster, index values have some grey multi-source heterogeneous characteristics. The purpose this paper construct a projection incidence model (GPIM) evaluate hazard characterised by heterogeneity information. Design/methodology/approach First, system established based formation mechanism disaster. Then, GPIM panel data constructed assess five cities in...
