The charge-spin interactions in multiferroic materials (e.g., BiFeO3) have attracted enormous attention due to their high potential for next generation information electronics. However, the weak and deficient manipulation of charge-spin coupling notoriously limits their commercial applications. To tailor the spontaneous charge and the spin orientation synergistically in BiFeO3 (BFO), in this re...

As is known to all, traditional clustering algorithms do not work well due to the topological features of protein-protein interaction networks. An improved clustering method based on bacteria foraging optimization (BFO) mechanism and intuitionistic fuzzy set, short for improved BFO, is proposed in this paper, in which the trigonometric function is used to define the membership degrees and the i...

This paper presents a recurrence network approach for the analysis of skin blood flow dynamics in response to loading pressure. Recurrence is a fundamental property of many dynamical systems, which can be explored in phase spaces constructed from observational time series. A visualization tool of recurrence analysis called recurrence plot (RP) has been proved to be highly effective to detect tr...

Bacterial Foraging Algorithm BFO is a recently proposed swarm intelligence algorithm inspired by the foraging and chemotactic phenomenon of bacteria. However, its optimization ability is not so good compared with other classic algorithms as it has several shortages. This paper presents an improved BFO Algorithm. In the new algorithm, a lifecycle model of bacteria is founded. The bacteria could ...

In this paper we review the integration of BFO’s theory of types with OntoClean’s notion of Rigidity, discuss our decision tree procedure for evaluating ontologies based on the integration, while also discussing its implementation as a Protégé 4 plugin, the BFO-Rigidity Decision Tree Wizard. Finally we provide a practical analysis of controversial and important ontological topics surrounding th...

The nanomechanical properties of BiFeO3 (BFO) thin films are subjected to nanoindentation evaluation. BFO thin films are grown on the Pt/Ti/SiO2/Si substrates by using radio frequency magnetron sputtering with various deposition temperatures. The structure was analyzed by X-ray diffraction, and the results confirmed the presence of BFO phases. Atomic force microscopy revealed that the average f...

The Bacterial Foraging Optimization (BFO) is one of the metaheuristics algorithms that most widely used to solve optimization problems. The BFO is imitated from the behavior of the foraging bacteria group such as Ecoli. The main aim of algorithm is to eliminate those bacteria that have weak foraging methods and maintaining those bacteria that have strong foraging methods. In this extent, each b...

In this paper, single-phase multiferroic ceramics of (1 x) BaTiO3 x BiFeO3 (BT x BFO) were synthesized by solid-solution method in the wide range of material composition (x1⁄4 0.025 – 1.0). The changes in crystal structure were confirmed via X-ray diffractions (XRD) and atomic pair distribution functions (PDFs). The room-temperature ME coupling was found to exhibit significant magnitude in the ...

Electrical and thermal properties of a carbon nanotube (CNT)/multiferroic BiFeO(3) (BFO)/Pt photovoltaic heterojunction are investigated for the first time. Enhanced photovoltaic properties (J(sc)≈ 2.1 μA cm(-2) and V(oc)≈ 0.47 V), as compared to the traditional polycrystalline BFO with indium tin oxide (ITO) as the top electrode, are observed due to the unique properties of CNT. An equivalent ...

The present research reports fabrication of nanoand submicrometer-sized BiFeO3 (BFO) powders from bismuth nitrate and iron chloride by a simple hydrothermal method at 180°C for 16 h in the presence of various MOH mineralizers (M = K, Na and Li). The final products were characterized by X-ray powder diffraction (XRD) and high-resolution transmission electron microscope (HR-TEM). Alkaline mineral...
