Researchers have discovered how unstructured segments of surface proteins regulate the biological function of a cell. Their study, published in Nature Communications, sheds new light on the interplay ...

Imagine 100 dots scattered in front of you. In a haphazard variation on connect-the-dots, start drawing lines between the points. How many lines can you draw without producing a triangle? A square? An ...

In this paper the generating function for the numbers of variations with repetitions and a certain type of restrictions is determined. The variations in question are connected with paths in ...
