Brain-inspired neural network navigation system with hippocampus, prefrontal cortex, and amygdala functions

We propose a brain-inspired neural network model consisting of the hippocampus, prefrontal cortex, and amygdala models for a navigation system that acquires specific knowledge in home environments from few experiences. The proposed model was evaluated in a home environment using a robot simulator. In the experiment, the robot determines a path for navigation based on the knowledge acquired by the brain-inspired model.2021 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS 2021), November 16-19, 2021, Hualien, Taiwa

Hibikino-Musashi@Home 2023 Team Description Paper

This paper describes an overview of the techniques of Hibikino-Musashi@Home, which intends to participate in the domestic standard platform league. The team has developed a dataset generator for the training of a robot vision system and an open-source development environment running on a human support robot simulator. The robot system comprises self-developed libraries including those for motion synthesis and open-source software works on the robot operating system. The team aims to realize a home service robot that assists humans in a home, and continuously attend the competition to evaluate the developed system. The brain-inspired artificial intelligence system is also proposed for service robots which are expected to work in a real home environment

Treatment Strategy for Pyoderma Gangrenosum: Skin Grafting with Immunosuppressive Drugs

Pyoderma gangrenosum (PG) is a relatively rare neutrophilic dermatosis presenting as a rapidly progressive and painful skin ulcer characterized by undermined borders and peripheral erythema. Immunosuppressive therapy is the first-line treatment for PG; however, large ulcers often take months or years to heal. Surgical treatments, such as negative pressure wound therapy (NPWT) and skin grafting, are still controversial due to the risk of inducing the pathergy phenomenon and eliciting PG development by traumatic factors. Herein, we report on four cases of PG treated with skin grafting, with or without NPWT, under the control of immunosuppressive drugs at our institution. All cases adapted well, but one case showed recurrence at the periphery of the grafted area five months postoperatively. The current patients were treated with the following doses of oral prednisolone (PSL): PSL 10 mg daily, PSL 5 mg daily + adalimumab 40 mg/week, PSL 12 mg + 6 mg of tacrolimus daily, and PSL 20 mg daily during skin grafting. No severe complications, including infections, were observed. Surgical treatments, such as skin grafting with or without NPWT, may accelerate wound healing, shorten the administration of analgesics and long-term immunosuppressive therapy, and reduce the risk of infection
