A partial envelope approach for modelling multivariate spatial‐temporal data
Canadian Journal of Statistics, EarlyView.Abstract In the new era of big data, modelling multivariate spatial‐temporal data is a challenging task due to both the high dimensionality of the features and complex associations among the responses across different locations and time points.

Journal of Combinatorial Theory, Series B, 1992 A matroid \(M\) is secret-sharing if there is a finite set \(S\) and a matrix \(A=\{a_{ij}:i\in I, j\in E(M)\}\) with entries in \(S\) such that for all \(X\subseteq E(M)\), the submatrix \(\{a_{ij}:i\in I, j\in X\}\) has precisely \(| S|^{rk(x)}\) distinct rows. The author shows that the Vamos matroid is not secret-sharing.

Deep Underground Science and Engineering, EarlyView.Cement infill shares compressive and shear stresses during loading, while interfacial friction hinders crack propagation and reduces stress concentration, improving the rock's load‐bearing capacity. Failure modes vary with crack inclination. Unfilled specimens show four modes.

Significant Secret Image Sharing Scheme Based on Boolean Operation
Cybernetics and Information Technologies, 2017 Traditionally, (k, n) secret image sharing is an approach of breaking down a secret image into n number of shadow images to assign them to n number of users, so that any k or more then k users can bring back the secret image.

, 2007 We consider the following problem. Let S be some secret. A collection of n people Ej share this secret in such a way that each Ej knows some information xj, for a certain fixed integer k, 2≤k≤n, the knowledge of any k of th x’s enables to find S easily, the knowlegde of less than k of the x’s leaves S undetermined.
