Interactive orbital proximity operations planning system [PDF]
An interactive, graphical proximity operations planning system was developed which allows on-site design of efficient, complex, multiburn maneuvers in the dynamic multispacecraft environment about the space station. Maneuvering takes place in, as well as

AGING MEDICINE, EarlyView.Across seven centers (2015–2023), we studied 1634 ATAAD patients undergoing TAR+FET and, after propensity matching (n = 699), compared elderly (≥ 60) versus non‐elderly (< 60) outcomes. Elderly patients had higher 30‐day mortality and complications (log‐rank p = 0.002), supporting individualized hybrid strategies, organ‐protective perioperative care ...

Anti‑acceleration Saturation Terminal Guidance Law Based on LSTM
Transactions of Nanjing University of Aeronautics and AstronauticsMissile acceleration saturation in a practical terminal guidance process may significantly reduce the interception performance. To solve this problem， this paper presents an anti-saturation guidance law with finite-time convergence for a three ...

Annals of Gastroenterological Surgery, EarlyView.We retrospectively analyzed clinical data from patients who underwent hepatectomy for hepatocellular carcinoma (HCC) using LCA‐based grading system. These findings provide a new risk stratification framework for the design of precision surgery to treat patients with HCC.

Tracking a Maneuvering Target using AUV
International Journal of Engineering and Advanced Technology, 2019 In this paper effort is made to track a maneuvering target using Unmanned Aerial Vehicles (UAV) with range, bearing and elevation measurements. Extended Kalman filter is preferred to processmeasurements tampered with noise. Algorithm to detect the maneuver of target is developed in this paper.
