We have observed photocarrier transport behaviors in ${\mathrm{BiFeO}}_{3}/{\mathrm{La}}_{1\ensuremath{-}x}{\mathrm{Sr}}_{x}{\mathrm{MnO}}_{3}$ (BFO/LSMO) heterostructures by using time-resolved synchrotron x-ray magnetic circular dichroism reflectivity. The magnetization of LSMO layers was used as a probe photo-induced carrier dynamics the photovoltaic BFO layers. During demagnetization proces...

Bacterial Foraging Optimization Algorithm (BFOA) has recently emerged as a very powerful technique for real parameter optimization. In order to overcome the delay in optimization and to further enhance the performance of BFO, this paper proposed a new hybrid algorithm combining the features of BFOA and Particle Swarm Optimization (PSO) for tuning a Fractional order speed controller in a Permane...

This paper presents the design of a Fuzzy Logic Controller (FLC) whose parameters are optimized by using Genetic Algorithm (GA) and Bacteria Foraging Optimization (BFO) for tip position control of a single link flexible manipulator. The proposed FLC is designed by minimizing the fitness function, which is defined as a function of tip position error, through GA and BFO optimization algorithms ac...

Numerous research groups are now utilizing Basic Formal Ontology (BFO) as an upper-level framework to assist in the organization and integration of biomedical and other types of information. In this paper, we attempt to elucidate the categories of role, disposition, function, and capability in BFO by means of definitions and examples. We also discuss tendency as one variety of disposition, and ...

This paper presents algorithms and lower bounds for several fundamental problems on the Exclusive Read, Concurrent Write Parallel Random Access Machine (ERCW PRAM) and some results for unbounded fan-in, bounded fan-out (or `BFO') circuits. Our results for these two models are of importance because of the close relationship of the ERCW model to the OCPC model, a model of parallel computing based...

Abstract Pure bismuth ferrite (BiFeO 3 , BFO) and ZnO thin films, as well BFO/ZnO ZnO/BFO composite films were successfully deposited by a sol-gel process on Pt/Ti/SiO 2 /Si FTO/glass substrates, respectively. The chemical composition, surface morphology, optical properties, multiferroicity systematically investigated. X-ray diffraction electron microscopy measurements used to determine the cry...

Numerous research groups are now utilizing Basic Formal Ontology (BFO) as an upper-level framework to assist in the organization and integration of biomedical information. This paper provides elucidation of the three BFO categories of function, role, and disposition, and considers two proposed sub-categories of artifactual function and biological function. The motivation is to help advance the ...

This paper proposes new metaheuristic algorithms for an identification problem of nonlinear friction model. The proposed cooperative algorithms are formed from the bacterial foraging optimization BFO algorithm and the tabu search TS . The paper reports the search comparison studies of the BFO, the TS, the genetic algorithm GA , and the proposed metaheuristics. Search performances are assessed b...

This paper addresses the use of dispositions in the Infectious Disease Ontology (IDO). IDO is an ontology constructed according to the principles of the Open Biomedical Ontology (OBO) Foundry and uses the Basic Formal Ontology (BFO) as an upper ontology. After providing a brief introduction to disposition types in BFO and IDO, we discuss three general techniques for representing combinations of...
