Figure 1 Spider plot for the yeast gene YBL008w (HIR1); position 1 the walker visits every first nucleotide of codons and moves a unit up if the nucleotide is G, down if it is C, right if it is A and left if it is T; position 2 the walker visits every second nucleotide of codons, and proceeds the same way; position 3 the walker visits every third nucleotide of codons, and proceeds the same way ...

This paper describes a vector space approach to solving the multidimensional (m-D) Yule-Walker equations for an arbitrary region of support. This approach leads to a solution that is simple to implement.

FIG. 1 Proposed mechanisms of joint lubrication (Redrawn after Walker and others, 1968) (Lancet, 1969; Dowson, Wright, and Longfield, 1969) and a further possibility, 'weeping' lubrication, has been proposed (McCutchen, 1959, 1962). More recently, the role ofelectrostatic forces at articulating surfaces has been investigated (Roberts, 1971). In each of these hypothetical mechanisms the thesis h...

over a wide range of speeds (Westneat, 1996; Walker and Westneat, 2000, 2002a,b). Swimming performance (determined in speed endurance tests for fishes) shows that pectoral propulsors in some species are capable of generating thrusts that can power speeds up to 10 body lengths s–1 (Walker and Westneat, 2002a,b). In addition, these species are highly maneuverable in complex three-dimensional reef...

In all domains of life, sliding clamps tether DNA polymerases to DNA to increase the processivity of synthesis. Clamp loaders load clamps onto DNA in a multi-step process that requires ATP binding and hydrolysis. Like other AAA+ proteins, clamp loaders contain conserved Walker A and Walker B sequence motifs, which participate in ATP binding and hydrolysis, respectively. Mutation of the glutamat...

OBJECTIVES To understand the opinion of the parents about the baby walker and compare the age of gait acquisition between infants that used a walker and those that did not. METHODS In this quali-quantitative study, an interview involving a semi-structured questionnaire was carried out with 26 parents, 14 of whose infants used the equipment (BWG) and 12 of whose infants did not (NBWG) prior to...
