IMAGE ENCRYPTION BASED ON IMPROVED LORENZ SYSTEM

Image Encryption Based on Improved Lorenz System

This paper proposes a new method to strengthen the nonlinear kinetic complexity and ergodicity of Lorenz system.Through the analysis of auto-correlation, frequency distribution, approximate entropy and information entropy, the improved Lorenz system has better dynamical properties than Lorenz system.According to NIST-800-22 test results, the chaoti

Redox driven B12-ligand switch drives CarH photoresponse

Abstract CarH is a coenzyme B12-dependent photoreceptor involved in regulating carotenoid biosynthesis.How light-triggered cleavage of the B12 Co-C bond culminates in CarH tetramer dissociation to initiate transcription remains unclear.Here, a series of crystal structures of the CarH here B12-binding domain after illumination suggest formation of u

From micro to macro, nanotechnology demystifies acute pancreatitis: a new generation of treatment options emerges

Abstract Acute pancreatitis (AP) is a disease characterized by an acute inflammatory response in the pancreas.This is caused by the abnormal activation of pancreatic enzymes by a variety of etiologic factors, which results in a localized inflammatory response.The symptoms of this disease include abdominal pain, nausea and vomiting and fever.These s

Mechanical Characteristics of Structures and Ground Deformation Caused by Shield Tunneling Under-Passing Highways in Complex Geological Conditions Based on the MJS Method

This study defined the height ratio of soft-rock strata and established a numerical model for analyzing shield construction in upper-soft, lower-hard composite strata together with field monitoring data.In this way, the influence of shield tunneling while passing under the pile foundation of the culvert at a short distance (the shortest distance is
