This report deals with the discussion of the findings obtained from the application of two computational intelligence methodologies for the detection of microcalcifications in screening mammography data. Genetic programming and inductive machine learning have been applied, in order to produce meaningful diagnostic rules for the medical staff. The data used in the experiments correspond to infor...

In this paper newly developed teaching-learning based optimization (TLBO) algorithm is applied for designing band pass (BP) and band stop (BS) digital IIR filters. TLBO is heuristic algorithm based on the social phenomenon of teaching-learning process. The effectiveness of purposed algorithm is validated by designing the BP and BS filters by approximating the magnitude response with Lp-norm err...

In both Pavlovian conditioning and human causal judgment, competition between cues is well known to occur when multiple cues are presented in compound and followed by an outcome. More questionable is the occurrence of competition between outcomes when a single cue is followed by multiple outcomes presented in compound. In the experiment reported here, we demonstrated blocking (a type of stimulu...

Stent implantation has become the new standard angioplasty procedure. Instent re-stenosis remains the major limitation of coronary stenting. Re-stenosis is related to patient-, lesionand procedure-specific factors. Patient-specific factors can not be influenced to any extent. Procedure-specific factors are affected by implantation technique and stent characteristics. Design and material influen...

School children often encounter traumatic injuries like a crown fracture. They create serious functional, esthetic and psychological problems. Achievement of promising restoration that preserves its aesthetics and strength is the greatest desire for both children and their parents and is a challenging task for the dentist. The restorative options in these cases usually include composite resin a...

Lecture 13 examined selection response with multiple traits. Here we consider measuring selection on multivariate phenotypes in some detail, as this is a very popular exercise in modern evolutionary biology. Moving to multiple traits poses no changes in measuring fitnesses of individuals (Lecture 12), but does require us to provide the multivariate versions of the univariate differentials S and...

uniparental disomy (upd) is a situation in which both members of a chromosome pair are inherited from one parent. this study has been conducted on a family with a five year-old healthy girl and a mentally retarded boy. the parents were first cousins and they both had robertsonian translocation between their long arm of chromosome 13 and 14 [45, xy t (13q14q)]. their affected son had a similar k...
