Classifiers trained on data sets possessing an imbalanced class distribution are known to exhibit poor generalisation performance. This is known as the imbalanced learning problem. The problem becomes particularly acute when we consider incremental classifiers operating on imbalanced data streams, especially when the learning objective is rare class(More)
The domain of radio astronomy is currently facing significant computational challenges, foremost amongst which are those posed by the development of the world's largest radio telescope, the Square Kilometre Array (SKA). Preliminary specifications for this instrument suggest that the final design will incorporate between 2000 and 3000 individual 15 metre(More)
The serum pharmacokinetics of recombinant human inhibin A (rh-inhibin A) and rh-activin A were examined in immature female Sprague Dawley-derived rats after iv and sc injection of the drugs. After iv administration of rh-inhibin A (120 micrograms/kg), the serum concentrations were described by a biexponential equation. The weight-normalized clearance was(More)

Cd-binding patterns in the hepatopancreas of the crayfish (Austropotamobius pallipes) have been analysed in response to the administration of a single dose of Cd ions. Four main components, with apparent molecular weights of 3-4, 12, 20 and greater than 70 K daltons, have been isolated from soluble cell fractions. The variation in molar metal/protein ratios(More)
Peronospora effusa is an obligate pathogen that causes downy mildew on spinach and is considered the most economically important disease of spinach. The objective of the current research was to assess genetic diversity of known historical races and isolates collected in 2014 from production fields in Yuma, Arizona and Salinas Valley, California. Candidate(More)
Measurements of spectral emittance in the infrared region from 6.8 to 13.3 micrometers were made with an airborne spectrometer at a rate of six spectra per second, on flights 650 meters above the olivine basalt flows at Pisgah Crater in the southern Californian desert. The spectra show chemical and mineralogical differences that can be related to(More)
The roles of recombinant human inhibin A (rh-inhibin A) and rh-activin A in regulating the pituitary and ovary of the adult female rat were examined. Serum and pituitary FSH and LH and serum estradiol and progesterone concentrations were evaluated at 1, 2, and 6-12 h after sc hormone administration on metestrus and on proestrus. A second study examined the(More)
In smokers a low dose of alcohol slightly improved decision time on a choice reaction-time task and in combination with tobacco resulted in significant improvement compared with placebo conditions. In nonsmokers decision time deteriorated significantly after a moderate dose of alcohol but not in smokers. The results are attributed to the stimulant action of(More)
