A geometric sequence goes from one term to the next by always multiplying or dividing by the same value. The number multiplied (or divided) at each stage of a geometric sequence is called the common ...

For years, a French mathematician searched for a proof that a gigantic number is prime. His method is still used 150 years ...

Two mathematicians have proved that a straightforward question—how hard is it to untie a knot?—has a complicated answer.

A linear sequence goes from one term to the next by always adding (or subtracting) the same value. The number added (or subtracted) at each stage of the linear sequence is called the common difference ...

Abstract: In this article, we introduce a novel compressed sensing (CS) scheme for sparse signal recovery in an effective method, namely compressed geometric sequential sensing (CGSS). This comes from ...

Introduction ‘One-off’ systematic case-finding for COPD using a respiratory screening questionnaire is more effective and cost-effective than routine care at identifying new cases. However, it is not ...
