Notions of sesquiconstructible complexes and odd iterated stellar subdivisions are introduced, and some of their basic properties are verified. The Charney-Davis conjecture is then proven for odd iterated stellar subdivisions of sesquiconstructible balls and spheres.

We introduce the notion of k-lower divergence for geodesic rays in CAT(0) spaces. Building on work Charney and Sultan we give various characterizations k-contracting using k-slim triangles. also characterize cube complexes sequences well-separated hyperplanes.

In this study, baroclinic-barotropic instability of the Martian atmosphere is studied for a zonal basic state based on Mariner 9 observations, using a spherical linear primitive equation model derived from a method of 3-D normal mode expansion. As a result of solving a matrix eigenvalue problem, a distinctly unstable mode at synoptic to planetary scales was found with a peak growth rate of 2.3 ...

The article considers the representation of war in Leo Tolstoy's artistic and journalistic work. The concept of "War" is a key notion in the writer's works. The paper describes the lexicon embodying the topic. To express the essence of the concept, Leo Tolstoy uses such words as sumasshestviye (madness), zlo (evil), and nasiliye (violence). The article analyzes the evolution of attitu...

O. basilicum leaves produce essential oils (LEO) rich in monoterpenes. The short half-life and water insolubility are limitations for LEO medical uses. β-Cyclodextrin (β-CD) has been employed to improve the pharmacological properties of LEO. We assessed the antihyperalgesic profile of LEO, isolated or complexed in β-CD (LEO/β-CD), on an animal model for fibromyalgia. Behavioral tests: mice were...

More than once we have heard that the Charney-Davis Conjecture makes sense only for odd-dimensional spheres. This is to point out that in fact it is also a statement about even-dimensional spheres. A conjecture of Heinz Hopf asserts that the sign of the Euler characteristic of a smooth Riemannian 2d-dimensional manifold of non-positive sectional curvature is the same for all such manifolds, tha...

Leopard, a well-known zebrafish mutant that has a spotted skin pattern instead of stripes, is a model for the study of pigment patterning. To understand the mechanisms underlying stripe formation, as well as the spot variation observed in leopard, we sought to identify the gene responsible for this phenotype. Using positional cloning, we identified the leopard gene as an orthologue of the mamma...
