Cluster Observations on Time‐of‐Flight Effect of Oxygen Ions in Magnetotail Reconnection Exhaust Region by T. Wu, S. Y. Fu, L. Xie, Q.‐G. Zong, X. Z. Zhou, C. Yue, W. J. Sun, Z. Y. Pu, Y. Xiong, S. J. Zhao, H. Zhang, F. B. Yu

“…In this study, we reported the D‐shaped velocity distribution of O+ ions produced by the ToF effect in the magnetotail reconnection exhaust based on the observations from the Cluster spacecraft. The observed cutoff velocity of O+ ions is smaller than that of H+ ions at the same time, which is different from the previous theoretical prediction. …”

Formation of raft-like assemblies within clusters of influenza hemagglutinin observed by MD simulations. by Daniel L Parton, Alex Tek, Marc Baaden, Mark S P Sansom

“…To investigate the effect of high local protein concentration, we have conducted coarse-grained molecular dynamics (CG MD) simulations of HA clusters in domain-forming bilayers. During the simulations, we observed a continuous increase in the proportion of raft-type lipids (saturated phospholipids and cholesterol) within the area of membrane spanned by the protein cluster. …”

Mirror mode structures ahead of dipolarization front near the neutral sheet observed by Cluster by G. Q. Wang, T. L. Zhang, M. Volwerk, D. Schmid, W. Baumjohann, R. Nakamura, Z. H. Pan

“…Abstract Magnetic compressional structures ahead of a dipolarization front (DF) on 30 August 2002 are investigated by using Cluster data. Our findings are as follows: (1) the structures, observed near the neutral sheet, are mainly compressional and dominant in BZ; (2) they are almost nonpropagating relative to the local ion bulk flow and their lengths are several local proton gyroradius; (3) the ion density increases when BT decreases; (4) ions are partially trapped by the structures with parallel and perpendicular velocities varying in antiphase; and (5) local conditions are favorable for excitation of the mirror instability, and we suggest that these structures are mirror mode‐like. …”
