The older continuous data are from key parameter data files. ... Note: Very high values of Solar Wind Speed, Solar Wind Pressure, IMF Magnitude and Bz, and Polar Cap Potential are likely indications that WIND has reentered the Earth's magnetosphere; such data is not indicative of solar wind conditions or impending severe geomagnetic disruption. ...

On optical characteristics of non­spherical scatterers Abstract. ... For example, the extinction cross­section C ext shows what fraction of the incident flux is absorbed and scattered by a particle. ... Therefore, in contrast to the spheres, for non­spherical particles the cross­section of radiation pressure is a vector too ~ C pr = C ext ~ R R \Gamma C sca ~g; (19) where R is the distance between the scatterer and the radiation source. ...

... A vector , that's what. ... Graphically, each stretch on the ground or velocity can be represented by an arrow in its direction, its length giving the magnitude--for instance, an arrow AB 200 mm (milimeters) long for the airplane's motion and another one BC 40 mm long, in the same direction, for the wind. ... Just as one can combine two vectors into one--their sum--so it is also possible to move in the opposite direction--given a single vector, find two vectors whose sum it is. ...

... DMITRY CHELKAK, 2010. ... Results In 2010 I made some progress in several research pro jects concerning a sharp behavior of the critical Ising model as the mesh size tends to zero (see the list in Sect. 4 below), and the most important one was done in collaboration with K. Izyurov (Geneva-St. Petersburg). As a starting point, we constructed a spinor generalization of Smirnov's fermionic observable in the critical Ising model for non-simply connected domains (or Riemann surfaces). ...
