For natural human-agent interaction, the recognition of important gestures to facilitate communication is necessary. Recent advances in technology have made it possible to use the human body as a means for this interaction. In this paper, we combine techniques to create a process flow which can discover and extract a body gesture, create a low-dimensional model, and then use it to recognize bod...

Robot force control that needs to be customized for the robot structure in unstructured environments with difficult-to-tune parameters guarantees robots’ compliance and safe human–robot interaction an increasingly expanding work environment. Although reinforcement learning provides a new idea adaptive adjustment of these parameters, policy often trained from scratch when used robotics, even sam...

Background Real-time interactive (RTI) MRI parameter manipulation during the scan [1] may potentially address challenges imposed by respiratory motion during a free-breathing cardiovascular magnetic resonance (CMR) acquisition. In this study, we propose an operator-guided processing that allows manipulation of navigator gating parameters in real-time. This approach was evaluated in healthy volu...

P2X receptors are involved in amplification of inflammatory responses in peripheral nociceptive fibers and in mediating pain-related signals to the CNS. Control of P2X activation has significant importance in managing unwanted hypersensitive neuron responses. To overcome the limitations of chemical ligand treatment, optical stimulation methods of optogenetics and photoswitching achieve efficien...

Knowledge-based organizations are hosts for multitudes of knowledge management (KM) episodes. Each episode is triggered by a knowledge need and culminates with the satisfaction of that need (or its abandonment). Within an episode, one or more of the organization’ processors (human and/or computer-based) manipulate knowledge resources in various ways in an effort to meet the need. This paper ide...

There are many examples of assistive devices for people with manipulative and locomotive disabilities. These devices enable disabled people perform many activities of daily living thus improving their quality of life. Disabled people are increasingly able to lead an independent life and play a more productive role in society. In the case of disabled children, such assistive devices have been sh...

The trophic state of many streams is likely to deteriorate in the future due to the continuing increase in human-induced nutrient availability. Therefore, it is of fundamental importance to understand how nutrient enrichment affects plant litter decomposition, a key ecosystem-level process in forest streams. Here, we present a meta-analysis of 99 studies published between 1970 and 2012 that rep...
