Interphase interaction in fine suspension flow

The article presents the modernization of the design of the universal seed mordant PSS-20 by installing an axial fan and air ducts for closed air circulation in the processing chamber, which will ensure the full use of the mordant, work safety and increase the productivity of cultivated crops. The main advantage of this design is that the seeds in the same plane as the suspension flow is affected by the air flow, which improves the penetration into the layer. Air ducts make it possible to reuse the suspension that has not settled on the seeds. This is achieved due to the closed lid design. During operation, the fan creates excessive pressure inside the seed stream and rarefaction outside, and so small drops of solution that have penetrated the seed stream are sucked in by the fan and re-fed into the stream.

Young Towers

AbstractWe show that certain billiard flows on planar billiard tables with horns can be modeled as suspension flows over Young towers (Ann. Math. 147:585–650, 1998) with exponential tails. This implies exponential decay of correlations for the billiard map. Because the height function of the suspension flow itself is polynomial when the horns are Torricelli-like trumpets, one can derive Limit Laws for the billiard flow, including Stable Limits if the parameter of the Torricelli trumpet is chosen in (1, 2).

K Theory

AbstractLet (Y, T) be a minimal suspension flow built over a dynamical system (X, S) and with (strictly positive, continuous) ceiling function f : X → ℝ. We show that the eigenvalues of (Y, T) are contained in the range of a trace on the K0-group of (X, S). Moreover, a trace gives an order isomorphism of a subgroup of K0(C(X) ⋊Sℤ) with the group of eigenvalues of (Y, T). Using this result, we relate the values of t for which the time-t map on the minimal suspension flow is minimal with the K-theory of the base of this suspension.
