A non-empty set X of a carrier A of an algebra A is called Q-independent if the equality of two term functions f and g of the algebra A on any finite system of elements a1, a2, . . . , an of X implies f(p(a1), p(a2), . . . , p(an)) = g(p(a1), p(a2), . . . , p(an)) for any mapping p ∈ Q. An algebra B is a retract of A if B is the image of a retraction (i.e. of an idempotent endomorphism of B). W...

In the present paper we investigate the problem of the existence of a value for differential games without Isaacs condition. For this we introduce a suitable concept of mixed strategies along a partition of the time interval, which are associated with classical nonanticipative strategies (with delay). Imposing on the underlying controls for both players a conditional independence property, we o...

Dear Editor: In comparing multifocal to monofocal intraocular lenses implanted to create monovision, Wilkins et al graciously recognized me as the first to publish on the use of full ( 2.75 diopters in the near eye) monovision. However, the statement that only 1 previous study of monovision in cataract surgery has reported overall spectacle independence as an outcome measure misses the point of...

A diverse group of proteins known as +TIPs specifically recognize the growing plus ends of microtubules in cells. Two recent papers on one such protein, CLIP-170, provide new insights into the cellular functions of +TIPs as well as the mechanism by which they track microtubule ends.
