The ability of lethally irradiated C57BL/6 mice to acutely reject H-2d bone marrow is due to a lymphocyte population that is NK1+, ASGM1+, CD4−, CD8−, CD3+. Transfer of spleen cells from C57BL/6 mice expressing these antigens into nonresponder 129 mice adoptively transfers the ability to reject H-2d marrow grafts. The specificity of this rejection maps to(More)
Matter-wave interferometry has become an essential tool in studies on the foundations of quantum physics and for precision measurements. Mechanical gratings have played an important role as coherent beamsplitters for atoms, molecules and clusters, because the basic diffraction mechanism is the same for all particles. However, polarizable objects may(More)
The superposition principle is fundamental to the quantum description of both light and matter. Recently, a number of experiments have sought to directly test this principle using coherent light, single photons, and nuclear spin states. We extend these experiments to massive particles for the first time. We compare the interference patterns arising from a(More)
Electrical potentials recorded extracellularly from the sinus gland of the isopod, Oniscus asellus, were stored on video tape with the aid of a digital-audio (DA) processor and a video cassette recorder (VCR). The DA processor transforms the analog signal to digital pulses of equal amplitude and converts these pulses into a television signal for recording(More)
