The Calculation of Indefinite Integrals of B-splines

The purpose of this paper is to give a useful formula for theindefinite integral of a B-spline. We show that the formuladoes not introduce any redundant knots, and, when used in conjunctionwith Cox's algorithm (1972), provides a very convenient methodfor computing the indefinite integral.     

MODULATION BY THIOLS OF THE MEROCYANINE 540-SENSITIZED PHOTOLYSIS OF LEUKEMIA CELLS, RED CELLS, AND Herpes simplex VIRUS TYPE 1

This paper reports on the role of endogenous and exogenous thiols in the merocyanine 540 (MC 540)-sensitized photoirradiation of L1210 leukemia cells, human erythrocytes, and human Herpes simplex virus type 1. Several measures taken to decrease the intracellular content of glutathione enhanced the cells' sensitivity to MC 540-sensitized photoirradiation while stimulation of glutathione biosynthesis or supplementation of the extracellular or extraviral thiol content decreased the photosensitivity of cells and viruses. Taken together, these data suggest that endogenous and exogenous thiols can modulate the sensitivity of cells and enveloped viruses to MC 540-sensitized photoirradiation. They also pose new questions as to the mechanism of MC 540-sensitized photolysis.     

The Range of Possible Values of f(x)

The purpose of this paper is to explain how to compute the rangeof possible values of a function of one variable, f(x), givenvalues of the function at n distinct points x₁ < x₂ <... < x_M–1 < x_M, and given a finite bound on thekth derivative of f: ||f^(k)|| L, 1 k n.
