Abstract We study the sparsity of solutions to systems linear Diophantine equations with and without non-negativity constraints. The a solution vector is number its nonzero entries, which referred as $$\ell _0$$ ? 0 -norm vector. Our main results are new improved bounds...

Cancer is one of the most challenging diseases because its complexity, variability, and diversity causes. It has been major research topics over past decades, yet it still poorly understood. To this end, multifaceted therapeutic frameworks are indispensable. Anticancer peptides (ACPs) promising...
