At present, significant progress has been made in the research of image encryption, but there are still some issues that need to be explored in key space, password generation and security verification, encryption schemes, and other aspects. Aiming at this, a digital image encryption algorithm was developed in this paper. This algorithm integrates six-dimensional cellular neural network with generalized chaos to generate pseudo-random numbers to generate the plaintext-related ciphers.

The discovery of new weak supramolecular interactions and supramolecular synthons is essential for directing self-assembly processes with enhanced precision, diversity, and functionality in complex molecular architectures. Here, we report the controlled self-assembly of diverse supramolecular architectures by a new directional bonding approach through the integration of radical-based dynamic covalent chemistry and supramolecular synthons. A novel macrocyclic synthon, , with a linear direction is constructed via radical-based dynamic covalent bonds from the phenothiazine building block substituted with two dicyanomethyl radicals.

Purpose: Pelvic ring fractures involving the iliopubic rami can cause functional impairment. Percutaneous retrograde fixation is a less invasive procedure when compared to traditional open approaches, however precise anatomical knowledge is crucial for safe screw placement. This study aims to describe the morphology of the iliopubic rami, define a safety corridor for percutaneous screw fixation, specially focusing on the relationships between the iliopubic rami and neurovascular structures.

Graph contrastive learning seeks to improve the efficacy of graph representation learning by comparing various graph representations. Existing approaches predominantly rely on node attributes or structural information for contrastive analysis. However, in real-world applications, node attribute information can be incomplete or entirely absent, while structure-enhancement methods often generate false positive samples.

Triangular resection is an effective repair technique for isolated segmental posterior leaflet prolapse in mitral valves at low risk for systolic anterior motion. It is applicable in the majority of such cases, is low risk, and has excellent long-term durability. Its simplicity and efficacy make it an essential part of every mitral surgeon's armamentarium.
