The ethyl acetate extract of the culture filtrate of the marine Ascomycete,
Leptosphaeria oraemaris (Linder) yielded a novel metabolite
designated by the common name leptosphaerin. An x-ray crystallographic
structure analysis was disproved by the synthesis of 3-acetoxy-S-(1,2-dihydroxyethyl)-
3-pyrrolin-2-one 1, starting with N,N-dibenzylhydroxylamine
47 and D-mannitol 44. Oxidation of 47 followed...
Six Tertiary units are exposed in the Onion Peak area near the town of Cannon Beach., Oregon. The units consist of: late Eocene to
early Miocene Oswald West mudstones (informal), middle Miocene Astoria Formation (Angora Peak sandstone and Silver Point mudstone members.-informal), middle Miocene basalts of intrusive and extrusive Depoe...
Certain 2- chioroethyl nitrosoureas have been demonstrated
to be highly specific inactivators of chymotrypsin
in vitro and glutathione reductase, both in vivo and in
isolated rat hepatocytes. The inactivation of glutathione
reductase in isolated hepatocytes resulted in an increased
sensitivity toward an adriamycin induced oxidative
challenge.
Prolonged incubation of 1-(2-chloroethyl)-3-([1-¹⁴...
In introducing the method of electrical images we first consider
the elementary problem of finding the electric field of a single point
charge and an infinite conducting plane. Then a problem involving a
conducting sphere and an exterior point charge is investigated and
the results are applied in the solution...
No-till pasture renovation can increase the quality and forage yield of underproductive pastures. Decreased erosion, lower costs, and less lost grazing time are advantages of no-till renovation compared to conventional renovation. Unwanted vegetation is first controlled with herbicides to decrease competition for introduced orchardgrass. Two field trials were conducted using...
Efficient time-series analysis can impact multiple application domains such as motif discovery in gene analysis or music data, extracting spectro-temporal patterns in acoustic scene analysis, or annotating and classifying electrical bio-signals (such as ECG, EEG, and EMG) for medical applications.
Time-series analysis involves a variety of tasks.
To predict future...
