Cyclins: wheels within wheels.
Cycimns were originally defined as proteins which are synthesized in each cell cycle and destroyed at every mitosis. Cyclins were discovered by T. Hunt and students at the Marine Biological Laboratory, Woods Hole, MA, duningthe 1982 Physiology Course (1). They labeled eggs ofthe sea urchin Arbacia punctulata with [35S]methionine after fertilization and analyzed the temporal pattern of protein s...
متن کاملThe rook problem on saw-toothed chessboards
A saw-toothed chessboard, or STC for short, is a kind of chessboard whose boundary forms two staircases from left down to right without any hole inside it. A rook at square (i, j) can dominate the squares in row i and in column j . The rook problem of an STC is to determine the minimum number of rooks that can dominate all squares of the STC. In this paper, we model an STC by two particular gra...
متن کاملDetecting wheels
A wheel is a graph made of a cycle of length at least 4 together with a vertex that has at least three neighbors in the cycle. We prove that the problem whose instance is a graph G and whose question is “does G contains a wheel as an induced subgraph” is NP-complete. We also settle the complexity of several similar problems.
متن کامل[Metal microchanelled fine-toothed comb use in the diagnosis of pediculosis].
BACKGROUND Methods for the diagnosis of Pediculus humanus var. capitis are controversial and most studies are based on direct visual exam. OBJECTIVE The objective of this study was to compare the diagnosis efficacy of both direct visual exam and the use of a metal microchanelled fine-toothed comb. METHODS 946 children and teenagers 4 to 19 years of age were examined. Each individual's hair ...
متن کاملWheels within Wheels: Making Fault Management Cost-Effective
Local design and optimization of the components of a fault-management system results in sub-optimal decisions. This means that the target system will likely not meet its objectives (under-performs) or cost too much if conditions, objectives, or constraints change. We can fix this by applying a nested, management system for the fault-management system itself. We believe that doing so will produc...
