Hadrosaurid fossils from the Liscomb Bonebed (Prince Creek Formation, North Slope, Alaska) were the first dinosaur bones discovered from the Arctic.While the Prince Creek Formation hadrosaurids were long identified as Edmontosaurus, a member of the sub-clade Hadrosaurinae, they were recently assigned to Storage Cabinets a newly-erected taxon, Ugrun

Living cells often need to measure Lighting chemical concentrations that vary in time, yet how accurately they can do so is poorly understood.Here, we present a theory that fully specifies, without any adjustable parameters, the optimal design of a canonical sensing system in terms of two elementary design principles: (1) there exists an optimal in

Soldering Stations We consider one type of stability (quasistability) of a vector combinatorial problem of finding the Pareto set.Under quasistability we understand a discrete analogue of lower semicontinuity by Hausdorff of the many-valued mapping, which defines the Pareto choice function.A vector problem on a system of subsets of a finite set (tr

Biomolecular computing devices always work in a complex biochemical environment.The weight which shows the importance degree of a specific signal may vary in different environments because it may be influenced by other signals even in the absence of direct interaction.To measure a signal accurately, several biomolecular computing devices always nee
