A Novel Technique for Drone Path Planning Based on a Neighborhood Dragonfly Algorithm.

Autonomous aerial drone navigation is a rapidly growing topic of research due to its vast application in various indoor applications, including surveillance, search and rescue missions, and environmental monitoring. Current research focuses on the implementation of neighborhood dragonfly algorithms (NDAs) for path planning for single and multiple drones in various indoor environments containing stationary and moving obstacles. The collaborative behavior of dragonflies is a key concept in the current study that helps in exploring the solution space effectively and results in a faster convergence rate.

Spectroscopic Characterization of Successive Phosphorylation of the Tissue Factor Cytoplasmic Region.

Tissue Factor (TF) is well known for its role during the activation of the coagulation pathway, but it is also critical for tumor biology and inflammation through protease activated receptor (PAR) 2 signaling. This signaling function is modulated by the successive phosphorylation of residues Ser253 and Ser258 within the TF cytoplasmic region (TFCR). This paper reports how we used NMR and spectroscopic methods to investigate the structural propensities of the unphosphorylated and phosphorylated forms of the TFCR.
