Abstract The article aims to highlight the usefulness of composite indicators applications as an analytical tool in guiding national security policies related multidimensional phenomena revealing its role measuring hybrid threats - part global risks. qualitative and quantitative research shows that use at country level is a relatively new topic, has enjoyed increased interest since 2021. origin...
The efficient design of digit-serial multipliers for special binary composite fields, F2nm where gcd(n, m) 1⁄4 1, is presented. These composite fields can be constructed via an irreducible pentanomial of degree nm but not an irreducible trinomial of degree nm. The conventional construction method for such digit-serial multipliers is to exploit the simplicity of pentanomials to obtain efficent l...
INTRODUCTION The ultimate goal in restorative dentistry has always been to achieve strong and permanent bond between the dental tissues and filling materials. It is not easy to achieve this task because the bonding process is different for enamel and dentin-dentin is more humid and more organic than enamel. It is moisture and organic nature of dentin that make this hard tissue very complex to a...
Cobalt based catalysts are promising bifunctional electrocatalysts for both oxygen reduction and oxygen evolution reactions (ORR and OER) in unitized regenerative fuel cells (URFCs) operating with alkaline electrolytes. Here we report a hybrid composite of cobalt nanoparticles embedded in nitrogen-doped carbon (Co/N-C) via a solvothermal carbonization strategy. With the synergistic effect arisi...
