چکیده
The undisputed father of mathematical problem solving is George Pólya (December 13, 1887 – September 7, 1985), one of the giants of classical analysis in the 20 century. He considered solving problems to be a practical art, one that can be taught and learned. His books on the subject How To Solve It (1945) and the two-volume set Mathematics and Plausible Reasoning (1954), and Mathematical Discovery (1962) are classics. The first, which has been translated into 21 languages, has sold more than a million copies over the years. Pólya’s influence goes far beyond the number of his books that were sold. His books form the basis for enlightened thinking in mathematics education in which student understanding is the goal rather than student memorization. Teachers throughout the world have enthusiastically adopted his suggestions and found that they worked. No one can estimate the number of students who, empowered with Pólya’s methods, have found that they actually can understand what they are doing in solving problems. However, the crusade to have Pólya’s ideas employed has not converted all the “heathens”; there are still strong factions who stress “learning how to do” over all other mathematical virtues.

PolyA-iEP: A data mining method for the effective prediction of polyadenylation sites
This paper presents a study on polyadenylation site prediction, which is a very important problem in bioinformatics and medicine, promising to give a lot of answers especially in cancer research. We describe a method, called PolyA-iEP, that we developed for predicting polyadenylation sites and we present a systematic study of the problem of recognizing mRNA 3 ́ ends which contain a polyadenylati...

Jakab was a lawyer in the Budapest office of the Assicurazioni Generali of Trieste, a large international insurance firm. Before joining the company he had had a private law practice. His real interests, however, lay in economics and statistics and he continued to study these on the side, in the hope of obtaining an academic position in economics, so that he could devote full time to research. ...
متن کاملBrain-specific polyA- transcripts are detected in polyA+ RNA: do complex polyA- brain RNAs really exist?
Transcripts encoded by 2 different rat genomic clones, rg13 and rg100, appear to be typical brain-specific polyA- RNAs, as defined by previous criteria (rare, polysomal, and postnatally expressed from single-copy genes). However, we have found by using a sensitive nuclease protection assay that low levels of these transcripts (10% and 3%, respectively) are detected in polyA+ RNA. To determine i...
متن کاملMore Aspects of Polya Tree Distributions for Statistical Modelling
The deenition and elementary properties of Polya tree distributions are reviewed. Two theorems are presented showing that Polya trees can be constructed to concentrate arbitrarily closely about any desired pdf, and that Polya tree priors can put positive mass in every relative entropy neighborhood of every positive density with nite entropy, thereby satisfying a consistency condition. Such theo...
متن کاملThe Influence of SV40 polyA on Gene Expression of Baculovirus Expression Vector Systems
The simian virus 40 polyadenylation signal (SV40 polyA) has been routinely inserted downstream of the polyhedrin promoter in many baculovirus expression vector systems (BEVS). In the baculovirus prototype Autographa californica multiple nucleopolyhedrovirus (AcMNPV), the polyhedrin promoter (very late promoter) transcribes its gene by a viral RNA polymerase therefore there is no supporting evid...
