This paper proposes a new memristor model and uses pinched hysteresis loops (PHL) to prove the characteristics of model. Then, 6D fractional-order memristive Hopfield neural network (6D-FMHNN) is presented by using this simulate induced current, bifurcation coexistence attractor fractional studied. Because 6D-FMHNN has chaotic characteristics, we also use generate random number apply it field image encryption. We make series analysis on randomness numbers security encryption, that encryption...

Fractional-order chaotic systems are widely used in the field of encryption because its initial value sensitivity and historical memory. In this paper, fractional-order definition Caputo is introduced based on a nonideal flux-controlled memristive Hopfield neural network model, when changing parameters (FMHNN) can generate different amount multi-scroll attractors. Some dynamical behaviors investigated by numerical simulation, especially analyzed coexistence bifurcation under orders coupling...

The River Basin Ecological Compensation Policy, which is an important starting point for the realization of ecological civilization, has changed perceptions local residents regarding ecosystem services (ES) and human well-being (HWB). Based on Millennium Ecosystem Assessment framework, we performed a face-to-face questionnaire-based survey among 807 randomly selected rural in Xin'an (XARB). Resident cognitive status was evaluated upstream downstream XARB according to ES individual HWB;...

Abstract Background The period of standardized training is a transitional stage when Generation Z newly graduated registered nurses (Gen NGRNs) change their role from student to nurse. Affected by the COVID-19, they lack clinical practice and practicum experience in emergency departments university studies. At beginning career, are under great pressure. Resilience one factors that reduce stress level increases endurance. It interest understand how this representative group gained played...

ObjectiveThe previous coronavirus disease 2019(COVID-19) epidemic inflicted significant psychological trauma on emergency and critical care nurses due to various factors, potentially leading job burnout. Despite the rise of positive psychology, little is known about post-traumatic growth experience these after pandemic. The aim this study was assess among nurses, in order provide managerial insights for developing effective strategies facilitating transformation nurses' negative emotions...

Summary In software engineering, UML activity diagrams in general can be useful for a modeling system functional behavior, ranging from the sequences of activities/actions business processes within an organization or among organizations down to detail algorithm. The stepwise refinement process makes more and complex. To guarantee behavior consistency correctness under refinement, must decomposed according divide‐and‐conquer strategy. Traditional decomposition methods adopt manual techniques...
