We discuss the problem of scheduling several jobs on a single machine so as to minimize the variance of the jobs' completion times. By exploiting the well-known pooled variance formula, we obtain a ...

Consider an N × n random matrix $Y_{n}=(Y_{ij}^{n})$ where the entries are given by $Y_{ij}^{n}={\textstyle\frac{\sigma _{ij}(n)}{\sqrt{n}}}X_{ij}^{n}$, the $X_{ij ...

Guiding organoid formation: Stem cell differentiation is controlled by the shape of the surrounding tissue. (Courtesy: Science 10.1126/science.aaw9021) An in-depth knowledge of human organs and how ...

A multi-national team of biologists has concluded that developmental evolution is deterministic and orderly, rather than random, based on a study of different species of roundworms. The findings are ...

A team of Korean researchers has developed a world-class Deterministic Random Bits Generator (DRBG). Random numbers are crucial values in computer security, such as secret keys and initialization ...
