on the kinetic depth effect.	the problem of the kinetic depth effect is revisited. we study how many points in how many views are necessary and sufficient to recover structure. the constraints in the cases where the velocities of the image points are known, and the positions of the image points are known with the correspondence between them established, are different and they have to be studied separately. in the case of two projections of any number of points there are infinitely many solutions, but if we regularize the pr ...	2008	2719982
bone bonding behavior of mgo-cao-sio2-p2o5-caf2 glass (mother glass of a.w-glass-ceramics).	in this study, it was found that a ca-p layer and a si layer were formed on the interface of the mother glass of apatite-wollastonite containing glass-ceramics (designated aw) and bone tissue. the dissolution of si, ca, and p from glass (mgo-cao-sio2-p2o5-caf2) is necessary to form a chemical film (a si layer and a ca-p layer). the three kinds of glasses used were 1) a mirror surface of the mother glass (mgo 4.6, cao 44.9, sio2 34.2, p2o5 16.3, caf 0.5 weight ratio) of aw (designated g-aw (mirro ...	1989	2738079
histamine concentration and ca2+ mobilization in arterial smooth muscle.	smooth muscle contraction is dependent on ca2+ entry from the extracellular space or release from intracellular stores. the sensitivity of these ca2+ sources to agonist concentration was evaluated by measuring myoplasmic [ca2+] (as estimated by aequorin), myosin phosphorylation, and isometric stress in the swine carotid media. high histamine concentrations produced transient elevations in [ca2+] and phosphorylation with rapid generation of near maximal stress. lower histamine concentrations prod ...	1989	2750885
