What are natural frequencies?

Why frequencies are natural

Research in mathematical cognition has shown that rates, and other interpretations of x/y, are hard to learn and understand. On the other hand, there is extensive evidence that the brain is endowed with a specialized mechanism for representing and manipulating the numerosities of sets – that is, frequencies. Hence, base-rates are neglected precisely because they are rates, whereas frequencies a...

What are Stem Cells?

  Stem cells are undifferentiated self regenerating multi potential cells. There are three types of stem cells categories by the ability to form after cells and correlated with the body’s development process. Totipotent: these stem cells can form an entire organism such as fertilized egg. Ploripotent: ploripotent cells are those that can form any cell in the body but cannot form an entire organ...

What are Natural Kinds ?

1. Two Questions Distinguish two questions about natural kinds. First, the naturalness question: what, if anything, makes a natural kind natural? Perhaps the members of a natural kind, unlike the members of an arbitrary group, stand in some natural similarity relation to one another. Perhaps they share an essence or some other natural feature. Or perhaps, as conventionalists argue, the boundari...

What are natural antisense transcripts good for?

NATs (natural antisense transcripts) are important regulators of eukaryotic gene expression. Interference between the expression of protein-coding sense transcripts and the corresponding NAT is well documented. In the present review, we focus on an additional, higher-order role of NATs that is currently emerging. The recent discovery of endogenous siRNAs (short interfering RNAs), as well as NAT...
