Phospholipids could exert their effect on membrane protein topology either directly by interacting with topogenic signals of newly inserted proteins or indirectly by influencing the protein assembly machinery. In vivo lactose permease (LacY) of Escherichia coli displays a mixture of topological conformations ranging from complete inversion of the N-terminal helical bundle to mixed topology and ...

In this article, we present the concept of supra paracompact spaces and study its basic properties. We elucidate its relationship with supra compact spaces and prove that the property of being a supra paracompact space is weakly hereditary and topological properties. Also, we provide some examples to show some results concerning paracompactness on topology are invalid on supra topology. Finally...

Compensation is crucial in the inductive power transfer system to achieve load-independent constant voltage or current output, near-zero reactive power, higher design freedom, and zero-voltage switching of driver circuit. This article proposes a simple, comprehensive, innovative graphic methodology for compensation topology realize output at zero-phase-angle frequencies. Four types graphical mo...

In this paper, a new cascaded multilevel inverter by capability of increasing the number of output voltage levels with reduced number of power switches is proposed. The proposed topology consists of series connection of a number of proposed basic multilevel units. In order to generate all voltage levels at the output, five different algorithms are proposed to determine the magnitude of DC volta...

In this paper, we define the new notion of quasi-prime ideal which generalizes at once both prime ideal and primary ideal notions. Then a natural topology on the set of quasi-prime ideals of a ring is introduced which admits the Zariski topology as a subspace topology. The basic properties of the quasi-prime spectrum are studied and several interesting results are obtained. Specially, it is pro...

A system of di®erential forms will establish a topology and a topological structure on a domain of independent variables such that is possible to determine which maps or processes acting on the system are continuous. Perhaps the most simple topology is that generated by the existence of a single 1-form of Action, its Pfa® sequence of exterior di®erentials, and their intersections. In such a top...

A large training set of fitness cases can critically slow down genetic programming, if no appropriate subset selection method is applied. Such a method allows an individual to be evaluated on a smaller subset of fitness cases. In this paper we suggest a new subset selection method that takes the problem structure into account, while being problem independent at the same time. In order to achiev...

A hesitant fuzzy set (HFS) and a cubic (CS) are two independent approaches to deal with hesitancy vagueness simultaneously. An HFS assigns an essential grade each object in the universe, whereas CS deals uncertain information terms of sets as well interval-valued sets. (CHFS) is new computational intelligence approach that combines HFS. The primary objective this paper define topological struct...
