We present a semi-analytical solution for the transient streaming potential response of a confined aquifer to pumping at a constant rate through a fully-penetrating line sink. Confined aquifer flow is assumed to occur without fluid leakage from the confining units and is thus described by the solution of Theis (1935). The confining units, which are typically more electrically conductive than th...
Polyacetylene (PA) polymers -(-CH=CH-), lead to large second hyperpolarizabilities (y) that increase with N. For small N the increase is quite rapid, eventually saturating (becoming linear in N) for N > N& Both experimental and theoretical attempts have been made to estimate N,Y,,. In 1994 this led to two Science papers, one obtaining NA, = 20 (semiempirical theory) and the other obtaining N,,,...

Methods Eleven healthy volunteers (20-31 years; 8-male 3-female) underwent MRI studies with a lower body negative pressure (LBNP) chamber. Imaging included quantitative phase contrast angiographic (PCA) measurements of blood volume flow in the carotid and vertebral arteries and ASL of the whole brain. An ASL sequence followed by PCA acquisition was performed at rest (control) and under -20mmHg ...
