A Novel Method to Estimate Base Drag and Burn Time from Flight Data Using Extended Kalman Filter [PDF]
Estimating highly spinning projectiles’ base drag and burn time by static trials is challenging. Drag profiles obtained using numerical methods or experimental or wind tunnel estimations should be updated using the estimates obtained from dynamic flight ...

The Formation and Transformation of Low‐Dimensional Carbon Nanomaterials by Electron Irradiation
Small, EarlyView.The article reviews irradiation phenomena in graphene‐ or graphite‐based nanomaterials from the scale of single atoms to tens or hundreds of nanometers. Observations dating back to the 1990s can now be explained on the basis of new results. The evolution of the understanding during three decades of research is presented, and the remaining problems are ...

Assessing Evidence Bias for Prehospital Tourniquet Use: A Scoping Review
World Journal of Surgery, Volume 49, Issue 6, Page 1471-1483, June 2025.The available evidence for the prehospital use of tourniquets is largely based on the military experience of high‐resource countries over the last 30 years. Though the lifesaving benefits of an appropriately applied tourniquet to stop catastrophic bleeding are undeniable, the potential consequences of tourniquet application differ greatly within ...
