This paper estimates the incidence of state corporate taxes on workers, landowners, and firm owners in a spatial equilibrium model in which corporate taxes affect the location choices of both firms and workers. Heterogeneous, location-specific productivities and preferences determine the mobility of firms and workers, respectively. Owners of(More)
Rhodopsin density and absolute threshold were determined in 11 patients with retinitis pigmentosa (RP) and nine normal subjects. In eight patients with familial histories suggesting recessive inheritance, the retinal areas studied showed marked decrease in sensitivity which was related to rhodopsin loss, probably via a log-linear relationship. The other(More)
Thresholds for detection of light by a dark-adapted test eye were measured while the other, non-test eye was either similarly dark adapted or while it was exposed to an intense red adapting field. An interocular effect that depends on the retinal location of the test was found: compared to the threshold during binocular dark adaptation, sensitivity(More)
Intense red light adaptation of one eye lowers the dark adapted ("absolute") threshold of a 661 nm, extrafoveal, 1.02 deg test flash in the other eye, by about 0.15 log units, for 10-15 min. This effect ("interocular sensitization") also occurs with an extrafoveal 491 nm test, but does not occur if the 661 nm test is foveal, or is made small and brief. Blue(More)
Extrafoveal thresholds for 660 nm test flashes were measured for the two eyes separately following 30 min of dark adaptation. Then, the right eye was exposed to red light while the left eye was covered. Thresholds in the adapted right eye recovered to a plateau raised about 0.3 log units above the level measured in the dark. In contrast, thresholds in the(More)
Introduction: At very high frequencies and field strength the ability to influence the B 1 fields by means of unique coil layout [1-4] or a high number of independent RF transmit coils is crucial to improve image homogeneity and parallel imaging performance [5-8]. Recent numerical calculations of designs based on short transmission line coils with up to 80(More)
