Assessment for Probability of Ship Capsizing due to Pure Loss of Stability in Quartering Seas
Journal of the Society of Naval Architects of Japan, 1991 This study presents a theoretical method for calculating probabilities of capsising due to pure loss of stability, for a ship running in short crested waves and fluctuating wind. The aim was to develop stability criteria of a ship in quartering seas making use of the risk analysis.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions
FEBS Letters, EarlyView.The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.
