In this work, we present the first use of reinforcement learning (RL) to investigate cooperative locomotion of microswimmers. Recent studies have demonstrated the prowess of RL as a new approach to investigate locomotion problems in fluids. Different RL techniques have been utilized to empower simple...
For each episode, or attempt to swim to the target, a pair of start and target positions are chosen randomly within disk regions as shown in Fig. 1. Fig. 1: Test navigation problem of navigating through unsteady cylinder flow. Swimmers are initialized randomly inside the red disk and are ...

The more I learned to swim within depths of my own being, the more I started experiencing silence even in the midst of chaos. Stillness, I observed, lurks just behind every experience throughout the day. Even though externally there may be many anxious moments but eventually there is not mu...
They need help learning how to swim in these new waters. 9. We are losing fundamental freedoms “due to an ill-informed populace distracted by rampant consumerism.” Just read Neil Postman and others. They make some very valid points. Are you reading this stuff or just ignoring it? I ...
flagella in the periplasmic space11. It is believed that the rotation of the periplasmic flagella (PFs) beneath the outer membrane drives the rolling of the spiral body12. The PF-dependent rotation of the cell body produces the thrust needed to swim in liquid media and crawl on a solid ...

The maze was artificially divided into four equal quadrants and the platform (10 cm in diameter), which was fixed 1 cm beneath the water surface, was placed in the center of the target quadrant. During the training period, the mice were allowed to swim freely for 60 s to find the ...

(sink or swim) Take 2 sets of notes – a regular one like you always do; and one of ideas – 3 things to do differently on Monday Life is Good in America. People will fight fiercely to keep what they have, but it is hard to motivate them to fight for more. This makes people ...
