Consider a massive random access scenario in which small set of $k$ active users out large number notation="LaTeX">$n$ potential need to be scheduled notation="LaTeX">$b\ge k$ slots. What is the minimum common feedback needed ensure t...

How to meet the demand for increasing number of users, higher data rates, and stringent quality-of-service (QoS) in beyond fifth-generation (B5G) networks? Cell-free massive multiple-input multiple-output (MIMO) is considered as a promising solution, which many wireless access points cooperate jointly serve users by exploiting coherent signal processing. However, there are still unsolved practi...

In this paper we propose a fine-grained workflow model, based on context-free graph grammars, in which the dependency relation between the inputs and outputs of a module is explicitly specified as a bipartite graph. Using this model, we develop an access control mechanism that supports provenance-aware security views. Our security model not only protects sensitive data and modules from unauthor...

accessibility to the improved (breeded) plant varieties is vital for agricultural and horticultural industries. providing food-security for growing population of the world, sustainable agricultural production, need for an increase in agricultural incomes, economic development and improvement are necessary for sustainable efforts in the field of plant breeding and improving. considering the spec...
