Polarization of Nova Delphini 1967
The light of Nova Delphini 1967 has intrinsic linear polarization, with both a small-amplitude fluctuation with a time-scale of days and a secular variation with a time-scale of months. Rotation of the plane o...

Germ-Free Mice and Lymphocyte Differentiation
Lymphocytes have been the object of intensive study for the last fifty years, (1) yet we know surprisingly little about them. Our ignorance is based in part on difficulties in locating individual members of a ...

Some Characteristics of Non-Two-Stream Irregularities in the Equatorial Electrojet
The analysis of VHF radar echoes from electron density irregularities in the equatorial electrojet indicate that there are two distinct types of irregularities in the region. One of these has previously been s...

Kinetic Studies on C550 and its Correlation to the Fluorescence Induction in Isolated Chloroplasts
In 1969 two papers by KNAFF & ARNON (1969) described a new component of isolated chloroplasts having an absorption spectrum with a peak at 550 nm. This component was designated C550 and was shown to undergo li...

Solitary Phenomena in Finite Dissipative Discrete Systems
Idealized nonlinear systems which are assumed to be infinite, continuous and nondissipative are well known to exhibit a variety of solitary-wave phenomena [1]. For example, the space-time dependence of the rel...

Second order necessary optimality conditions for semi-infinite programming problems
A unified second order theory for extremum problems is applied to obtain second order necessary conditions for semi-infinite programming problems. The well known first order conditions are included. An applica...

Progress in Cloning the Transforming Gene from Chemically-Transformed Mouse Cells
DNA was extracted from a variety of chemically-transformed mouse fibroblast lines, and used as a donor for the transfection of NIH3T3 cells. Some of these DNAs were able to induce the appearance of transformed...

Generalized Inverses of Matrices and Their Applications
Although generalized inverses were discovered and rediscovered many times before (see, e.g., [85], [82] and the annotated bibliography in [71]), it was the 1955 paper [76] by Penrose which started generalized ...
