In this paper, we review five heuristic strategies for handling context-sensitive features in supervised machine learning from examples. We discuss two methods for recovering lost (implicit) contextual information. We mention some evidence that hybrid strategies can have a synergetic effect. We then show how the work of several machine learning researchers fits into this framework. While we do ...
A synergetic effect between carbon nanotubes (CNTs) and graphene on diopside (Di) scaffolds was demonstrated. 3D network architecture in the matrix was formed through the 1D CNTs inlaid among the 2D graphene platelets (GNPs). The mechanical properties of the CNTs/GNPs/Di scaffolds were significantly improved compared with the CNTs/Di scaffolds and GNPs/Di scaffolds. In addition, the scaffolds e...
The racemic oxovanadium(IV) salmmen complexes, [VO((rac)-(4-X-salmmen))] (X = C12C10C5 (1), C16 (2), and C18 (3); salmmen = N,N'-monomethylenebis-salicylideneimine) with "banana shaped" molecular structures were synthesized, and their ferroelectric properties were investigated. These complexes exhibit well-defined hysteresis loops in their viscous phases, moreover, 1 also displays liquid crysta...
TiO2-coated Ag nanorods (Ag@TiO2 NRs) have been fabricated as multifunctional surface-enhanced Raman scattering (SERS) substrates. Uniform TiO2 shells could sufficiently protect the internal Ag NRs against oxidation and sulfuration, thus the temporal stability of SERS substrates was markedly improved. Meanwhile, due to the synergetic effect between crystalline TiO2 and Ag, the nanocomposites co...
In this paper we present a new algorithm based on ant colony metaphor for examining numerical optimization problems. The ants’ search behavior consists of a parallel searches on distributed randomly points. Using synergetic effect and tandem running ants try to calibrate with another ants to exchange information about the fruitful positions of search space. The position of the searching point i...
A synergetic effect of sonication with yolk-shell nanocatalyst for green synthesis of spirooxindoles
A synergetic effect of ultrasonic irradiation and yolk–shell nanocatalyst was examined for the synthesis spirooxindoles from isatin, malononitrile cyclohexanone. It found this contributory can be accelerated desired reaction toward obtaining highly pure products in excellent yields short times. The contains melamine anchored onto magnetic Fe3O4 nanoparticles were applied as active base catalyst...
Palm oil mill effluent (POME) is considered the most environmentally harmful when discharged without proper treatment. In addition to conventional biological treatment methods, physicochemical techniques are alternative methods treat POME as polishing or post-treatment meet discharge water quality standards set by authorities. Recently, electroflotation (EF) has gained popularity in wastewater ...
Drug resistance is a primary hindrance for efficiency of chemotherapy. To investigate whether Fe3O4-magnetic nanoparticles (Fe3O4-MNPs) loaded with adriamycin (ADM) and tetrandrine (Tet) would play a synergetic reverse role in multidrug resistant cell, we prepared the drug-loaded nanoparticles by mechanical absorption polymerization to act with K562 and one of its resistant cell line K562/A02. ...
