Within the hierarchy of motion perception, the dorsolateral middle superior temporal area (MSTd) is optimally suited for the analysis of the complex motion patterns that are directly useful for visually guided behaviour (e.g. computation of heading). Recent electrophysiological and psychophysical evidence suggests the existence of 'detectors' in MSTd that are specialised for complex motion patt...

A typical shadow-eliminating algorithm is presented in this paper. Algorithms for vehicle detection, edge detection and shadow detection are also given. If the shadow is not separated from the vehicle, the next traffic control processes, like vehicle classification, tracking and speed calculation, will be rather difficult. Our approach for shadow processing runs in real time in low-cost hardwar...

Space-planted populations derived from 'Holt' and 'Oto' indiangrass, Sorghastrum nutans (L.) Nash, were used to obtain heritability estimates for forage yield, in vitro dry matter digestibility (IVDMD), crude protein, and heading date and to determine their genotypic correlations. Heritability estimates were determined by variance component analyses and by parent-progeny regression. Average nar...

Daylength controls flowering in many plant species. Early in the twentieth century, Garner and Allard (1920) first described the phenomenon of plants that flower only when daylength is longer or shorter than a particular threshold, named long-day and shortday plants, respectively. Rice is a shortday plant; flowering (termed “heading” in rice and other cereals) is promoted by short daylength. Ho...

In Washington, over fifty percent of the wheat produced under rainfed conditions receives less than 300 mm of annual precipitation. Hence, a winter wheat-summer fallow cropping system has been adopted to obtain adequate moisture for winter wheat production. Current tilled fallow systems are exposed to significant soil degradation from wind and water erosion. As a result, late-planted no-till fa...

practical and clinical aspects. In the present edition, notwithstanding the brief period at the author's disposal for revision (1) a new section on the Toxaemia of Pregnancy has been added under Pathological Pregnancy ; (2) the section on Fever in the Puerperium in Part VIII of the first edition has been entirely rewritten and brought up-to-date under the heading of Morbidity in the Puerperium ...
