In the title mol-ecule, C(24)H(26)N(2)O(2), the two indol-2-one units, which are connected by a C=C double bond, are almost coplanar with an inter-planar angle of 6.8 (1)°. On cooling from 293 to 120 K, the space group changes from P2(1)/n to P2(1). Two intra-molecular C-H⋯O hydrogen bonds occur.

Background Phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2) plays an important role in various cellular processes: not only in calcium signalling as a precursor for the second messenger Ins(1,4,5)P3, but also in the regulation of ion channels, cytoskeletal dynamics and many other events connected to the plasma membrane. Since many of the molecules participating in the process of endocytosi...

Introducing certain types of morphisms for general (abstract) convexity spaces, we give several ways for reducing the (Calder-) Eckhoff partition problem to simpler equivalent forms (finite, point-convex, interval spaces; restricted form, i.e. with distinct points). With additional results (to appear in a forthcoming paper) we show how the general problem can be reduced to its restricted versio...

Given a graph G = (V; E) and k positive integers n1; n2; : : : ; nk such that ∑k i=1 ni = |V |, we wish to 2nd a partition P1; P2; : : : ; Pk of the vertex set V such that |Pi| = ni and Pi induces a connected subgraph of G for all i; 16 i6 k. Such a partition is called a k-partition of G. A graph G with n vertices is said to be k-partitionable if there exists a k-partition of G for any partitio...

0. Introduction. The Fatou set of a holomorphic map f : P is the largest open subset of P on which iterates of f form a normal family. The complement of is called the Julia set when k = 1, and it is well known that the Julia set is the closure of the set of repelling periodic points. When k = 2, however, even product maps suffice to show that the structure of P2\ is more intricate. For instance...
