[1] Using two conjunction events of the Time History of Events and Macroscale Interactions during Substorms (THEMIS) imagers and spacecraft as well as the Super Dual Auroral Radar Network (SuperDARN) and Poker Flat Incoherent Scatter Radars, we show that longitudinally narrow flow bursts in the nightside polar cap can precede poleward boundary intensifications (PBIs) that are followed by equato...
A series of traverses has been conducted for validation the National Aeronautics and Space Administration Ice, Cloud, land Elevation Satellite 2 (ICESat-2) on flat interior Antarctic ice sheet. Global Navigation System data collected three separate 88S Traverses intersect 20% ICESat-2 reference ground tracks have precisions better than ±7 cm biases less ?4 cm. Data from these were used to asses...
We propose possible new string theories based on local world-sheet symmetries corresponding to extensions of the Virasoro algebra by fractional spin currents. They have critical central charges c = 6(K + 8)/(K + 2) and Minkowski space-time dimensions D = 2+16/K for K ≥ 2 an integer. We present evidence for their existence by constructing modular invariant partition functions and the massless pa...
in the present study, the growth of phospholipids' micelles in canola oil by chemical pretreatment and their separation by using membrane technology was investigated. aqueous solutions of calcium chloride (1% w/w) and edta (150 mm) were added to canola oil miscella before ultrafiltration process. ultrafiltration was conducted by a flat sheet pvdf membrane with two different mwcos (50 kda, m116,...
Motivated by the redrawing of hot glass into thin sheets, we investigate the shape and stability of a thin viscous sheet that is inhomogeneously stretched in an imposed nonuniform temperature field. We first determine the associated base flow by solving the long-time-scale stretching flow of a flat sheet as a function of two dimensionless parameters: the normalized stretching velocity α and a d...
Context. An approach to the problem of estimating several physical properties heliospheric current sheet (HCS) local structure from a single spacecraft observation point view was published in 2003. This method, HYperbolic TAngent ROtation (HYTARO), is based on following two main assumptions: (a) that HCS locally flat, and (b) its magnetic topology described by modified Harris field.
