A visual stimulus at a particular location of the visual field may elicit a behavior while at the same time equally salient stimuli in other parts do not. This property of visual systems is known as selective visual attention (SVA). The animal is said to have a focus of attention (FoA) which it has shifted to a particular location. Visual attention normally involves an attention span at the loc...

Histochemical and ultrastructural analyses were carried out to assess structural and biochemical changes in date palm roots pretreated with salicylic acid (SA) then inoculated with Fusarium oxysporum f. sp. albedinis (Foa). Flavonoids, induced proteins, and peroxidase activity were revealed in root tissues of SA-treated plants after challenge by Foa. These reactions were closely associated with...

N are often conducted under the stipulation that an impasse is to be resolved using final-offer arbitration (FOA). In fact, FOA frequently is not needed; in Major League Baseball, for instance, more than 80% of the salary negotiations that could go to arbitration instead reach a bargained agreement. We show that the risk aversion of at least one side explains this phenomenon. We then model pay ...

Calves born to multiparous Holstein cows fed during the last 30 d of pregnancy 2 different cobalt sources [cobalt glucoheptonate (CoPro) or pectin (CoPectin)], folic acid (FOA), and rumen-protected methionine (RPM) were used study neonatal immune responses after ex vivo lipopolysaccharide (LPS) challenge. Groups (n = 12 calves/group) CoPro, FOA+CoPro, FOA+CoPectin, FOA+CoPectin+RPM. weighed at ...

Control valve is a kind of essential terminal control component which is hard to model by traditional methodologies because of its complexity and nonlinearity. This paper proposes a new modeling method for the upstream pressure of control valve using the least squares support vector machine (LS-SVM), which has been successfully used to identify nonlinear system. In order to improve the modeling...

Objectives: Fixed orthodontic appliances (FOAs) may cause a temporary deterioration of oral hygiene with corresponding gingival inflammatory changes. Optimal oral hygiene and dietary changes are essential in order to avoid periodontal inflammation. The present study investigates to what extent the recommendations made by the orthodontist are followed by young patients. Materials and methods: A ...

A novel method is proposed to establish the pancreatic cancer classifier. Firstly, the concept of quantum and fruit fly optimal algorithm (FOA) are introduced, respectively. Then FOA is improved by quantum coding and quantum operation, and a new smell concentration determination function is defined. Finally, the improved FOA is used to optimize the parameters of support vector machine (SVM) and...

We feel honoured to contribute this chapter to a volume that is devoted to recognizing the unique place that Andrew Mathews has had in the study of anxiety and the anxiety disorders. From the beginning of his career, he set the course for research on anxiety, including psychophysiology, treatment and, most recently, cognitive mechanisms. This chapter will relate predominantly to Mathews’ contri...
