Inequalities for the Modified k-Bessel Function

International Journal of Analysis and Applications, 2017
The article considers the generalized k-Bessel functions and represents it as Wright functions. Then we study the monotonicity properties of the ratio of two different orders k- Bessel functions, and the ratio of the k-Bessel and the k-Bessel functions ...

Multi-Attribute Graph Estimation With Sparse-Group Non-Convex Penalties

IEEE Access
We consider the problem of inferring the conditional independence graph (CIG) of high-dimensional Gaussian vectors from multi-attribute data. Most existing methods for graph estimation are based on single-attribute models where one associates a scalar ...

Learning Multi-Attribute Differential Graphs With Non-Convex Penalties

IEEE Access
We consider the problem of estimating differences in two multi-attribute Gaussian graphical models (GGMs) which are known to have similar structure, using a penalized D-trace loss function with non-convex penalties.

Shelf-life determination of tiger-toothed Croaker (Otolithes ruber) during flake ice storage

‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2011
Quality of tiger-toothed croaker stored in flake ice was studied for 19 days by sensory, chemical (total volatile basic nitrogen (TVB-N)), (thiobarbituric values (TBA)), pH and microbial (total viable count, TVC) methods.
