A novel swarm intelligence optimization approach: sparrow search algorithm
Systems Science & Control Engineering, 2020 In this paper, a novel swarm optimization approach, namely sparrow search algorithm (SSA), is proposed inspired by the group wisdom, foraging and anti-predation behaviours of sparrows.

Security enhancement using a novel two-slot cooperative NOMA scheme [PDF]
, 2020 In this letter, we propose a novel cooperative non-orthogonal multiple access (NOMA) scheme to guarantee the secure transmission of a specific user via two time slots. During the first time slot, the base station (BS) transmits the superimposed signal to

Low levels of classical BSE infectivity in rendered fat tissue
Veterinary Research, 2018 BSE infectivity in mesentery fat is most likely associated with embedded nervous tissue. To prove this mesentery containing celiac ganglion was taken from oral BSE infected cattle in different stages of the disease and from one control animal.

The potential of chemical bonding to design crystallization and vitrification kinetics
Nature Communications, 2021 Tailoring the crystallization kinetics of materials is important for targeting applications. Here the authors observe a remarkable dependence of crystallization and vitrification kinetics and attribute it to systematic bonding changes for a class of ...

RF-Access: Barrier-Free Access Control Systems with UHF RFID
Applied Sciences, 2022 Traditional RFID-based access control systems use flap barriers to help manage pedestrian access and block unauthorized staff at any entrance, which requires visitors to swipe their cards individually and wait for the opening of the blocking body ...

Safe reinforcement learning for dynamical systems using barrier certificates
Connection Science, 2022 Safety control is a fundamental problem in policy design. Basic reinforcement learning is effective at learning policy with goal-reaching property. However, it does not guarantee safety property of the learned policy.
