This study aimed to develop a suitable buccal mucoadhesive nanoparticle (NP) formulation containing fluconazole for the local treatment of oral candidiasis. The suitability of the prepared formulations was assessed by means of particle size (PS), polydispersity index, and zeta potential measurements, morphology analysis, mucoadhesion studies, drug entrapment efficiency (EE), in vitro drug relea...

Teamwork is a critical capability in multi agent envi ronments Many such environments mandate that the agents and agent teams must be persistent i e exist over long periods of time Agents in such persistent teams are bound together by their long term common interests and goals This paper focuses on exible teamwork in such per sistent teams Unfortunately while previous work has investigated exib...

What is the problem we wish to solve when we try to construct a rational economic order? On certain familiar assumptions the answer is simple enough. If we possess all the relevant information, if we can start out from a given system of preferences, and if we command complete knowledge of available means, the problem which remains is purely one of logic. That is, the answer to the question of w...

Based on local optimality, a novel sequential detection scheme is proposed in this paper. The performance of the proposed scheme is compared with that of the sequential probability ratio test (SPRT) and truncated SPRT (TSPRT). The proposed scheme is shown to have higher efficiency, lower complexity, and smaller computational requirements than the SPRT at the cost of partially lower detectabilit...

Population-based methods are often considered superior on multimodal functions because they tend to explore more of the fitness landscape before they converge. We show that the effectiveness of this strategy is highly dependent on a function’s global structure. When the local optima are not structured in a predictable way, exploration can misguide search into sub-optimal regions. Limiting explo...

We consider the problem of quickest detection of abrupt changes for processes that are not necessarily independent and identically distributed (i.i.d.) before and after the change. By making a very simple observation that applies to most well-known optimum stopping times developed for this problem (in particular CUSUM and Shiryayev–Roberts stopping rule) we show that their optimality can be eas...

The role of population size is investigated within a neutrality induced local optima free search space. Neutrality decouples genotypic variation in evolvability from fitness variation. Population diversity and neutrality work in conjunction to facilitate evolvability exploration whilst restraining its loss to drift, ultimately facilitating the evolution of evolvability. The characterising dynam...

Pipe cleaning is currently the most effective method to improve cleanliness and corrosion resistance of pipes. In this paper, a new pipe proposed, combining mechanical chemical cleaning, offline tank online cycle cleaning. Through experiments characterization morphology changes, mechanism pickling passivation Q235 steel was explored, entire process microstructure changes on wall’s surface analy...
