Review paper: A Briefing to Grey Systems Theory [PDF]
Abstract Grey systems theory, probability theory, fuzzy systems theory and rough set theory are known as four uncertain systems scientific methodologies. After thirty years of development, grey systems theory has formed its own disciplinary framework, whose content includes grey philosophy, grey mathematics, processing and technology systems of grey ...

Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

Grey evaluation model and algorithm of network attack effectiveness
Network attack effect evaluation is a complex problem especially in the operation of network attack and de-fence, in which the information is incomplete and vague.The grey system theory is a powerful tool to solve the problem which has a little and ...

In the present work, we have identified a transcriptional signature based on the differential expression of six genes (BCL2&MAST4, HSH2D&LAT2, METRN&PITPNM2) that would facilitate the early detection of T‐cell acute lymphoblastic leukemia (T‐ALL) patients prone to a poor treatment response and could be implemented at diagnosis, along with other risk ...

Study on Prediction of Grain Yield Based on Grey Theory and Fuzzy Neutral Network Model [PDF]
In order to improve the prediction precision of grain yield, the grey system theory and the fuzzy neutral network are combined to construct the combined prediction model, which is applied in predicting the grain yield.

Grey relation projection model for the ecological sensitivity
Ecological sensitivity analysis is an important foundation of ecological city planning. Because of the complexity and relative factors' diversity in a region, many evaluation methods are being gradual explored and improved. Environment system is almost a

Neuronal assembly dynamics in supervised and unsupervised learning scenarios [PDF]
The dynamic formation of groups of neurons—neuronal assemblies—is believed to mediate cognitive phenomena at many levels, but their detailed operation and mechanisms of interaction are still to be uncovered.

Hospital Location Selection with Grey System Theory [PDF]
The facility location selection is one of the most important decisions for investors and entrepreneurs. It is a strategic issue besides often decides the fate of such a facility. In this kind of strategic decisions, decision makers should take into account various objectives and criteria and the process of location selection is inherently complicated ...
