In this paper, a three-dimensional (3D) impact-angle-control guidance law is proposed based on the approaches of nonsingular terminal sliding mode control and fixed-time convergence theory to intercept a maneuvering target.The guidance law is derived based on the coupled 3D engagement dynamics.To intercept the target with an expected impact angle,

Introduction and purpose: Gallbladder cancer is the most common neoplasm of the bile duct.Early GBC is usually asymptomatic, but is prone to early metastases.This means that most GBC cases are diagnosed very late, and this contributes to the poor prognosis of this disease.Less than 20% of GBC cases qualify for a potentially curable surgical resecti

Some recent Hockey Puck studies have found regression of liver cirrhosis after antiviral therapy in patients with hepatitis C virus (HCV)-related liver cirrhosis, but there have been no reports of complete regression of esophageal varices after interferon/peg-interferon and ribavirin combination therapy.We describe two cases of complete regression

In the past decade, research on ultrasound therapy in obstetrics and gynecology has rapidly developed.Currently, high-intensity ultrasound has been widely used in clearance clinical practice, while low-intensity ultrasound has gradually emerged as a new trend of transitioning from pre-clinical research to clinical applications.Low-intensity pulsed

Summary: Many experimental studies have examined behavioral and electrophysiological responses of mosquitoes to odors.However, the differences across studies in data collection, processing, and reporting make it difficult to perform large-scale analyses combining data from multiple studies.Here we extract and standardize data for 12 mosquito specie
