By Lyapunov control, we present a proposal to drive quasi-particles into a topological mode in quantum systems described by a quadratic Hamiltonian. The merit of this control is the individual manipulations on the boundary sites. We take the Kitaev's chain as an illustration for Fermi systems and show that an arbitrary excitation mode can be steered into the Majorana zero mode by manipulating t...

riparian vegetation is a component of river system that performs certain basic functions including primary vegetative production, protecting stream banks from erosion, trapping sediments, promoting water quality, wildlife habitat and fisheris, forage for livestock, etc. in this research, spatio-temporal change of vegetation riparian area of aghbolagh-river as an upstream of karoon-river for 65-...

A proposed desalinization project that would affect the entire upper Red River basin, Oklahoma-Texas, would, if completed, raise the possibility of invasion by red shiner, Cyprinella lutrensis, into stream reaches from which it has been restricted by naturally high salinity. Because introduced red shiners are known to impact native fish communities, we asked if red shiner could have an adverse ...

in this paper, the dierential transform method (dtm) is applied to the fisherequation. this method can be used to obtain the exact solutions of fisherequation. finally, we give some examples to illustrate the suciency of themethod for solving such nonlinear partial dierential equations. these resultsshow that this technique is easy to apply.

The activity of ribulose 1,5-diphosphate (RuDP)-carboxylase and RuDP-oxygenase was measured in crude leaf extracts of the tobacco (N . tabacum ) phenotypes which differed with respect to their gene constitution and with respect to their photosynthetic and photorespiratory activity. The green wild type (JWB) which carried the discussed two nuclear factors su and aur in the condition su/su Aur/Au...

in this work, ito/pet (indium tin oxide / polyethylene terephthalate) electrode structure which provides biocompatibility, mechanical stability and flexibility is fabricated. flexible ito/pet implantable electrode array for a retina has been developed. the electrode array is fabricated on a thin pet/ito substrate and is encapsulated using, su-8, an insulating material. pet substrate and su-8 po...
