Two-step verification does not imply two-factor authentication. Conversely, two-factor authentication may not require two-step verification. With ubiquitous bio-sensors, we can strive for one-step two-factor authentication for wearable computing applications.

Primer T he growth and development of all eukaryotes depends on the process of asymmetric cell division, in which a single cell gives rise to two genetically identical cells that adopt distinct fates [1,2]. Asymmetry occurs when two cells are exposed to different environmental stimuli or when specific mRNAs or proteins (known as cell fate determinants) are segregated unequally. In recent years,...

Copulas are a useful tool to model multivariate distributions. While there exist various families of bivariate copulas, the construction of flexible and yet tractable copulas suitable for high-dimensional applications is much more challenging. This is even more true if one is concerned with the analysis of extreme values. In this paper, we construct a class of one-factor copulas and a family of...

Many engineers and scientists perform one-factor-at-a-time (OFAT) experiments. They will continue to do so until they understand the advantages of designed experiments over OFAT experiments, and until they learn to recognize OFAT experiments so they can avoid them. A very effective way to illustrate the advantages of designed experiments, and to show ways in which OFAT experiments present thems...

Identifying important factors from a large number of potentially highly nonlinear and computationally expensive black box model is difficult problem. Morris screening Sobol’ design are two commonly used model-free methods for doing this. In this article, we establish connection between these seemingly different in terms their underlying experimental structure further exploit to develop an impro...
