Motivated by applications in phenome-wide association studies (Phe-WAS), we consider in this paper simultaneous testing of columns of high-dimensional cross-covariance matrices and develop a multiple ...

This article proposes an optimization model for simultaneous estimation of an origin-destination (O-D) matrix and a travel-cost coefficient for congested networks in a logit-based stochastic user ...

Polycyclic aromatic hydrocarbons (PAHs) originate from the incomplete combustion of organic matter and, due to their toxic and carcinogenic effects, are monitored in the environment with strict ...

Solution: det (A) = −5, and for n×n matrix adj (A) has determinant (det A)^ (n−1). Here n = 3, so det (B) = (−5)^ (2) = 25. For feedback or story ideas, reach us at timesnoweducation@timesgroup.com ...
