Koza has previously shown that the power of a genetic programming system can often be enhanced by allowing for the simultaneous evolution of a main program and a collection of automatically de ned functions (ADFs). In this paper I show how related techniques can be used to simultaneously evolve a collection of automatically de ned macros (ADMs). I show how ADMs can be used to produce new contro...

Software agents have shown considerable promise in many fields. Thus, control structures for such software agents raise important research issues. This thesis goals are (1) to design control structures for software agents, (2) to solve real world problems with these models, and by doing this, (3) to discover some principles of control mechanisms of software agents. Therefore, the major question...

0.1 Challenge 1 If we consider that G(x, t) and W (x, t) are harmonic functions in time, then there exist functions g(x) and w(x) such that G(x, t) = g(x) cos(ωt) and W (x, t) = w(x) cos(ωt). Reeplacing these two expressions in the problem (1), we have that −ω2w(x) cos(ωt)− c2w′′(x) cos(ωt) = g(x) cos(ωt), which implies that −ω2w(x) − c2w′′(x) = g(x). On the other hand, the function W (x, t) sa...

. The research reported here is the result of an investigation of several aspects of the control structure of programming languages. By control structures we mean _ • programming environments or operations which specify the sequencing and interpretation rules for programs or parts of programs. This dissertation attempts to demonstrate the thesis: complexity diminishes and clarity increases to a...

background & aim: the most common primary brain tumors of the central nervous system are gliomas. among a number of different biomolecular events, a strong relation between oxidative stress pathways and the development of this cancer has been proved. oxidative stress (os) is the consequence of an imbalance between pro-oxidants and antioxidants towards pro-oxidants. the pro-oxidants cause lipid ...

background: in recent years, neoadjuvant chemoradiation and subsequent surgical resection with total mesorectal excision has been shown to increase local control with decreased toxicity. neoadjuvant chemoradiotherapy is the standard treatment for locally advanced rectal cancer. in this study we evaluated the efficacy a cox-2 inhibitor on pathologic response, sphincter preservation and acute tox...

germinal matrix-intraventricular hemorrhage (ivh) is the most common variety of neonatal intracranial hemorrhage and is characteristics of the premature infant. the importance of the lesion relates not only to its high incidence but to their attendant complications (ic: hydrocephalus). brain sonography is the procedure of choice in diagnosis of germinal matrix- intraventricular hemorrhage and h...

To define a role for the angiopoietin/Tie2 system in astrocytoma angiogenesis, we examined the expression of angiopoietin-1 (Ang1) and angiopoietin-2 (Ang2) in these tumors by immunohistochemistry and in situ hybridization. Furthermore, we studied in vitro the effects elicited by glioblastoma cell-secreted Ang1 or by recombinant Ang1 on functions of endothelial cells (ECs). Our observations of ...

The objective of this study was to determine the effectiveness of topical administration of honey in prevention of or reduction in post-surgical peritoneal adhesions in dog. The study was conducted on 18 adultfemale mixed-breed dogs with a mean ± SD weight of 20 ± 4.25 kg. A standardized surgical trauma (serosaltrauma model) was made in the dogs’ descending colon to induce adhesion formation. T...
