Lip control system is an innovative human-computer interface specially designed for people with tetraplegia. This paper presents an evaluation of the lower lip potential to control an input device, according to Fitts' law (ISO/TS 9241-411:2012 standard). The results show that the lower lip throughput is comparable with the thumb throughput using the same input device under the same conditions. These results establish the baseline for future research studies about the lower lip capacity to operate ...

Abstract A computational pipeline combining texture analysis and pattern classification algorithms was developed for investigating associations between high‐resolution MRI features and histological data. This methodology was tested in the study of dentate gyrus images of sclerotic hippocampi resected from refractory epilepsy patients. Images were acquired using a simple surface coil in a 3.0T MRI scanner. All specimens were subsequently submitted to histological semiquantitative evaluation. The ...

While attribute-based access control (ABAC) is a promising technique to govern interactions in the Internet of Things (IoT), most existing ABAC models are designed to run on remote servers or gateway devices. This scenario is misaligned with recent trends toward IoT decentralization, such as the Swarm, which expects devices to autonomously share resources, making their own access decisions for enhanced privacy and reliability. In this article, we propose SmartABAC: a fast, concise, and expressive ...

We present a low-overhead mechanism for self-sovereign identification and communication of IoT agents in constrained networks. Our main contribution is to enable native use of Decentralized Identifiers (DIDs) and DID-based secure communication on constrained networks, whereas previous works either did not consider the issue or relied on proxy-based architectures. We propose a new extension to DIDs along with a more concise serialization method for DID metadata. Moreover, in order to reduce the security ...
