چکیده
A new species, Cheilocostus borneensis, is described. Specimens were collected in Sarawak in 1987 and Kalimantan in 2000, but only intensified surveys of gingers in Sarawak in 2002-2004 provided sufficient collections to recognize the new species, which is here described and illustrated. It is closely related to the widespread C. globosus from which it differs by the chocolate-brown sheaths, absence of axillary shoots on vegetative stems, larger leathery leaves, and by its calyx that is not prickly.

Constructions for 4-Polytopes and the Cone of Flag Vectors
We describe a construction for d-polytopes generalising the well known stacking operation. The construction is applied to produce 2-simplicial and 2-simple 4-polytopes with g2 = 0 on any number of n ≥ 13 vertices. In particular, this implies that the ray l1, described by Bayer (1987), is fully contained in the convex hull of all flag vectors of 4-polytopes. Especially interesting examples on 9,...

متن کاملThe rigid amphipathic fusion inhibitor dUY11 acts through photosensitization of viruses.
Rigid amphipathic fusion inhibitors (RAFIs) are lipophilic inverted-cone-shaped molecules thought to antagonize the membrane curvature transitions that occur during virus-cell fusion and are broad-spectrum antivirals against enveloped viruses (Broad-SAVE). Here, we show that RAFIs act like membrane-binding photosensitizers: their antiviral effect is dependent on light and the generation of sing...
