We consider the number of hops, the residual energy, and aggregation factor
, and then a distributed dynamic aggregation tree algorithm based on constrained-degree is established.
Ginkgolide B, a component of Ginkgo biloba, is a known platelet aggregation factor
antagonist, and the herb, alone or with analgesics, has been associated with intracranial bleeding events.
In sponges, cell adhesion is mainly achieved through species-specific interactions of a type of proteoglycan molecule termed aggregation factor
Studies of the Microciona aggregation factor
(MAF) have thus far been focused upon its self-binding characteristics.
The aggregation factor
(MAF) of Microciona sponge is depicted as a species specific, adhesive proteoglycan molecule configured as a sunburst-type structure with a central ring, or core, from which numerous elongated arms project (1).
The cell surface sugar residues, as defined by these lectin probes, may bind to the aggregation factor
(MAF) or to endogenous lectins; they may also function as adhesins towards bacteria, algae, etc.
Furthermore, a sponge aggregation factor
has been revealed that is a sulfated polysac-charide (Coombe and Parish, 1988).
The aggregation factors
present in methanol extract of feces of nymphs, males and females of bedbug, C.
