Phase relations in unbalanced two-way telephone repeaters

Owing to the wide use of repeaters in modern high-grade long-distance telephone circuits and the importance of obtaining a high repeater gain without singing, the authors of the paper investigate f

Phase relations, solubility and growth of potassium titanyl phosphate, KTP.

Potassium titanyl phosphate is an unusually good nonlinear optical material whose use is constrained because of the difficulty of growing crystals.

Phase relationships and conductivity of the polymer electrolytes: Poly(ethylene oxide)/lithium tetrafluoroborate and poly(ethylene oxide) /lithium trifluoromethane sulfonate.

The prospect of highly conductive polymer electrolytes has become an important aspect of the development of an all solid state rechargeable battery.

Phase Retrieval Receivers Based on Alternative Projections for Coherent Optical Communications

We review recent progress on phase retrieval receivers (Rx) employing alternative projections for coherent optical communications.

Phase Retrieval with Fast Convergence Employing Parallel Alternative Projections and Phase Reset for Coherent Communications

Phase-retrieval (PR) receivers can reconstruct complex valued signals using only direct detection without the use of any optical carriers.

Phase seeding of a terahertz quantum cascade laser

The amplification of spontaneous emission is used to initiate laser action.

Phase separation and 1/f noise in low-T-MI colossal magnetoresistance manganites

We report studies of the 1/f noise in La5/8-yPryCa3/8MnO3 (y = 0.3 - 0.4) which exhibits the metal-insulator transition (MIT) in zero magnetic field, and in Pr1-xCaxMnO3 (0.30.5), where the tran

Phase Separation in Cd sub (1-x) Zn sub x Te Grown by Molecular Beam Epitaxy.

The ternary system Cd sub (1-x) Zn sub x Te has been a leading candidate for use as a lattice matched buffer layer for a variety of Hg-containing II-VI compounds.

Phase Separation of Ba sub 2 YCu sub 3 O sub 7 in an Oxygen Gradient

Schmalzried has discussed the phenomena of demixing which may take place in solid solutions or oxide compounds when subjected to an oxygen gradient.

PHASE SEPARATION OF POLYMER SOLUTIONS IN ELONGATIONAL FLOW.

We have studied the phase separation behavior of polymer solutions in two-dimensional elongational flows that are sufficiently weak to avoid the coil-strectch transition.
