We discuss Lepp-centroid versus Lepp-midpoint algorithms for Delaunay quality triangulation. We present geometrical results that ensure that the centroid version produces triangulations with both average smallest angles greater than those obtained with the midpoint version and with bigger smallest edges, without suffering from a rare looping case associated to the midpoint method. Empirical stu...

Aim: The line from the midpoint of the sternocleidomastoid muscle to the midpoint of the clavicle was considered the surface projection of the brachial plexus in the supraclavicular region in a previous report using radiological and anatomic techniques. The needle insertion site was the point between the clavicular one-third and cervical two-thirds of this line. The aim of the present study was...

We construct a symplectic, globally defined, minimal-variable, equivariant integrator on products of 2-spheres. Examples of corresponding Hamiltonian systems, called spin systems, include the reduced free rigid body, the motion of point vortices on a sphere, and the classical Heisenberg spin chain, a spatial discretisation of the Landau–Lifshitz equation. The existence of such an integrator is ...

A‎s we know, developing mathematical models and numerical procedures that would appropriately treat and solve systems of linear equations where some of the system's parameters are proposed as fuzzy numbers is very important in fuzzy set theory. For this reason, many researchers have used various numerical methods to solve fuzzy linear systems. In this paper, we define the concepts of midpoint a...

OBJECTIVES How human chronotype is correlated to nutrient and food-group intakes and dietary behavior remains to be elucidated. We cross-sectionally examined the association between the midpoint of sleep and these dietary variables in young Japanese women. A calculated halfway point between bedtime and rise time was used as midpoint of sleep. METHODS The subjects were 3304 female Japanese die...

We present a theory of conversation comprehension in which a l ine of the conversation is "understood" by relat ing it to one of seven possible "points". We define these points, and present examples where it seems plausible that the fai lure to "get the point" would indeed constitute a fai lure to understand the conversation. We argue that the recognition of such points must proceed in both a t...

The obligate methylotroph Methylophilus methylotrophus contains three distinct soluble cytochromes c. The major cytochromes, cytochrome cH (about 50% of the total) and cytochrome cL (about 42%), were similar in most respects to the cytochromes cH and cL of the facultative methylotroph Pseudomonas AM1 [O'Keeffe & Anthony (1980) Biochem. J. 192, 411-419]. Cytochrome cH had a high isoelectric poin...
