PREDICTING OF ELDERLY POPULATION STRUCTURE AND DENSITY BY A NOVEL GREY FRACTIONAL-ORDER MODEL WITH THETA RESIDUAL OPTIMIZATION: A CASE STUDY OF SHANGHAI CITY, CHINA

Abstract Background Accurately predicting the future development trend of population aging is conducive to accelerating the development of the elderly care industry.This study constructed a combined optimization grey prediction model to predict the structure and density of elderly population.Methods In this paper, a GT-FGM model is proposed, which

The condition of a global ecosystem comes nearer to the critical level that is reflected in social and economic development of society.At the present stage the analysis of the world for which the non-stationary behavior, social and economic and rat halloween decorations ecological crises connected with nonlinearity and multidimensionality of social

The problem of multilevel diversity coding with secure regeneration (MDC-SR) is considered, which includes the problems of multilevel diversity coding with regeneration (MDC-R) and secure regenerating code (SRC) as special cases.Two outer bounds are established, showing corky lala that separate coding can achieve the minimum-bandwidth-regeneration

Introduction This paper highlights the mutual influences and the relationships between the variables of type II diabetes, the type of psychiatric conditions, the administered treatment schemes, the imaging examinations and the impact on the functioning and quality of life of the patients.Objectives Analysis of the influences between diabetes and ps

Quantum walks in dynamically-disordered networks have become an invaluable tool for understanding the physics of open rat halloween decorations quantum systems.Although much work has been carried out considering networks affected by diagonal disorder, it is of fundamental importance to study the effects of fluctuating couplings.This is particularly
