Aiming at the problems of small key space and weak resistance to differential attacks in existing encryption algorithms, we proposed a chaotic digital image encryption scheme based on an optimized artificial fish swarm algorithm and DNA coding.First, the key is associated with the ordinary Sun Cap image pixel through the MD5 hash operation, and the
Background and Aims: To date, more than 2,500 micro-RNAs (miRNAs) have been discovered and some of which are considered to play important roles in window of implantation (WOI).In this study, we aimed to evaluate the efficacy of a miRNA-based endometrial receptivity analysis (MIRA) in IVF patients.Method: Patients who were planning for frozen-thawed
The risk evaluation of occupational exposure to xylene was conducted to provide a basis for the formulation of policies on the prevention and control of occupational hazards of xylene and to fill the gap in this field.In this study, a number of xylene-related companies in seven industries from 2020 to 2023 were collected as research subjects, and t
Intangible assets are often characterized by high initial costs, low or declining costs, scale economies, collective consumption and imperfect Clear Sinus substitution.In an economic entity, the more it comes out of a certain element, the unit costs are reduced.Most licensed products can be consumed by more people at a time.The imperfect substituti
Discretionary firm donation is usually related to the stakeholder theory and corporate social performance.Although theoretical explanations for this social behavior are pervasive in related literature, empirical modeling remains underdeveloped.We developed an explanatory structural model of discretionary firm donation using firm and industry level
