Therefore, we define foraging as the conjunction of the two tasks (searching and homing) with consideration of communication: Searching Robots inspect the search space for targets (or food).
CLL cells also can stimulate stromal cells through lymphotoxin-β-receptor activation, resulting in CXCL13 secretion and remodeling of the stromal cell compartment, linking CLL cell homing with shaping of survival niches and access to proliferation stimuli.
These included the SA-10 Grumble, a Mach-6 mobile system with a 60-mile range deployed in both strategic and tactical versions; the SA-11 Gadfly, a Mach-3 semiactive radar homing system with a range of 17 miles; the SA-12 Gladiator, a track-mobile replacement of Ganef; the SA-13 Gopher, a replacement for Gaskin; and the SA-14, a shoulder-fired Grail replacement.
Each vehicle carried four canister-launched, semiactive radar homing missiles, with a range of about 7.5 miles, plus guidance and tracking equipment in a rotating turret.
To exclude a potential impact of the AdNK4 and DAS pretreatments on extravasation and homing, with an interference with the evaluation of metastasis growth, we normalized the data of bioluminescence of each animal with the value obtained at 24 h (Supplementary Figure S2a).
Colicins belong to the group of homing nucleases with an HNH motif (Sui et al. 2002; Hsia et al. 2004; Stoddard 2005).
Goddard and Burt (1999) have proposed a model of the group I intron life cycle that begins with intron homing into an intronless allele followed by intron/HEG degeneration.
However, RA-conditioned MoDC, which had acquired a gut-homing phenotype (Fig. 3a), also induced a gut-homing phenotype on stimulated T cells via decreased expression of CLA, rendering most of the stimulated T cells potentially gut-homing with a β7+CLA− phenotype (Fig. 4b).
"Austerlitz" contains fascinating asides about such disparate matters as military fortifications, capitalist architecture and the secret lives of moths; a charming tale about a boy's homing pigeon, who walks home with a broken wing, and a short history of the land on which the Liverpool Street Station was built in London.
Similar effects of movement were noted in populations with natal homing (Appendix A), indicating that natal homing had virtually no impact on the predictions of our model.
New Caledonian crows craft tools to retrieve inaccessible grub; blue jays count; African gray parrots converse with humans, who entrust homing pigeons with carrying messages across enemy lines.
