Among the approaches to build a Multi-Net system, Stacked Generalization is a well-known model. The classification system is divided into two steps. Firstly, the level-0 generalizers are built using the original input data and the class label. Secondly, the level-1 generalizers networks are built using the outputs of the level-0 generalizers and the class label. Then, the model is ready for pat...

the most problematic weed in summer crops in alashthar town is ground cherry (physalis divaricata). in this research, the emergence pattern of this weed in sugar beet and wheat crop was investigated during 2006- 2007. seed dormancy was also studied from october to may in two depths 0 and 10 cm, based on a factorial experiment. the results indicated that the emergence of this weed starts late ap...

Clinical translation of photoacoustic (PA) imaging can be facilitated by integration with commercial ultrasound (US) scanners to enable dual-modality imaging. An array-based US scanner was modified for hand-held PA imaging. The performance was benchmarked in terms of signal-to-noise ratio (SNR), axial spatial resolution and sensitivity. PA images of a tube, filled with methylene blue (MB; appro...

Ferrocene has been investigated as a platform for developing protonmotive electrostatic drivers for molecular motors. When two 3-pyridine groups are substituted to the (rapidly rotating) cyclopentadienyl (Cp) rings of ferrocene, one on each Cp, it is shown that the (Cp) eclipsed, pi-stacked rotameric conformation is preferred both in solution and in the solid state. Upon quaternization of both ...

The CFMC summarized in the Coral Fishery Management Plan (FMP) the information available regarding types and frequency distribution of marine bottoms (Coral FMP 1995; CFMC 1984). The distribution by coast and depth varies. For example, at depths less than 10 fathoms, the north coast includes gravel, hard and rocky bottoms. The East Coast includes reefs, corals, and hard bottoms. Reefs, hard and...

The host efficiencies of corn, sorghum, soybean, and wheat were compared for a Kansas population of Belonolaimus sp. under greenhouse conditions. In a related field study conducted in 1989 and 1990, the responses of Belonolaimus sp. and Pratylenchus scribneri populations to eight cropping regimes were monitored at depths of 0-30 and 31-60 cm in sandy soil. With the exception of alfalfa, all cro...

The Southern Ocean is anomalously rich in benthos. This biodiversity is native, mostly endemic and perceived to be uniquely threatened from climateand anthropogenicallymediated invasions. Major international scientific effort throughout the last decade has revealed more connectivity than expected between fauna north and south of the worlds strongest marine barrier—the Polar Front (the strongest...
