We motivate the description of heavy-electron metals in terms of concepts from the Kondo problem. These concepts are used to discuss magnetism and superconductivity in heavy-electron systems.

Quantum noise reduction to levels nearly 1 dB below the standard quantum limit are reported for light frequencies near an atomic Na resonance.

First experimental results have been obtained on strong magnetic X-ray dichroism in the M(4,5) absorption spectra of magnetically ordered rare earth materials, in accordance with recent prediction

Pulse-code modulation system is described which provides 24 channels, with 8 kc/s sampling, 70 quantization steps and amplitude compression.

We experimentally characterize implementation penalties due to a limited effective number of bits (ENOB) of the analog-to-digital converter (ADC) for Nyquist shaped 16-, 64-, and 256-ary quadrature

An N-channel DOES (Double heterostructure Opto-Electronic Switch) has been demonstrated as in the case of the p-channel device, there is a high impedance state without light emission and a low impe

Multimoding is n impairment caused by mode conversions and multiple reflections in the horn antenna and the circular waveguide system.

The growth of Dataphone* Digital Service1 (DDS)+ and the needs of new services such as Picturephone* Meeting Service2 (PMS) require a substantial increase in digital long-haul transmission capacity

The concept of optical fibers made from a single material was the subject of a recent article; 1 the advantages of such fibers are their construction of low-loss fused silica and their freedom from
