Scholarly digital libraries increasingly provide analytics to information within documents themselves. This includes information about the logical document structure of use to downstream components, such as search, navigation, and summarization. In this paper, the authors describe SectLabel, a module that further develops existing software to detect the logical structure of a document from exis...

Groups of rats experienced mechanical stimulation of the vagino-cervical region in induce pseudopregnancy at various intervals from 0900 h on dioestrus -- 1 (D -- 1) to 1800 h on D -- 2. Twenty-four of 26 rats which were stimulated on D -- 1 experienced immediate pseudopregnancy whereas when the stimulus was given on D -- 2, 39 of 45 rats continued to cycle and the latest time when such mechani...

Due to the increasing use of digital medical images, a need exists to develop an approach for automatic image annotation, which provides textual labels for images. Thus added labels can be used to access images using textual queries. Automatic image annotation can be separated into two individual tasks: feature extraction and image classification. In this paper, the authors present feature extr...

Eight male subjects were exposed to either bright light or dim light between 0600 and 0900 h for 3 consecutive days each. Relative to the dim light condition, the bright light treatment advanced the evening rise in plasma melatonin and the time of sleep termination (sleep onset was held constant) for an average approximately 1 h. The magnitude of the advance of the plasma melatonin rise was dep...

A 60 year old man with panhypopituitarism due to a large meningioma and prolonged and exaggerated thyroid stimulating hormone (TSH) responses is described. Initial investigations showed a subnormal urinary free cortisol concentration, a low serum cortisol taken at 0900 hours, and a low free T4 concentration. The TSH was towards the upper end of the normal range. Subsequently pituitary function ...

Rhythmicity of tryptophan metabolism via the kynurenine pathway has been demonstrated in man. Normal subjects given 3 g of tryptophan at 0900 hours excreted almost three times the quantity of kynurenine, kynurenic acid, and xanthurenic acid than did subjects given the same dose at 2100 hours. Other metabolites of the kynurenine pathway varied in the same fashion but with lesser magnitude. In co...

Overnight basal insulin requirements to maintain eugycemia were determined in six insulin-requiring diabetic subjects using a feedback-controlled (closed loop) insulin infusion system. Mean hourly insulin infusion rates, required to maintain plasma glucose concentrations at approximately 100 mg/dl, were remarkably stable from 2400 h to 0600 h; however, a twofold to threefold increase in insulin...
