Dexterous manipulation requires both strength, the ability to produce fingertip forces of a specific magnitude, and dexterity, the ability to dynamically regulate the magnitude and direction of fingertip force vectors and finger motions. Although cortical activity in fronto-parietal networks has been established for stable grip and pinch forces, the cortical regulation in the dexterous control ...

44 Dexterous manipulation requires both “strength”, the ability to produce fingertip 45 forces of a specific magnitude; and “dexterity”, the ability to dynamically regulate the 46 magnitude and direction of fingertip force vectors and finger motions. While cortical 47 activity in fronto-parietal networks has been established for stable grip and pinch forces, 48 the cortical regulation in the de...

Multi-hop wireless networks, such as sensor, ad hoc and mesh networks, suffer from permanent topology dynamics due to unstable wireless links and node mobility. Stable addressing, as needed for reliable routing, in such evolving, challenging network conditions is thus a difficult task. Efficient multihop wireless communication in these networks then requires a fully decentralized, scalable rout...

Our opinion is influenced by those of others we connect to in social networks. How to model opinion dynamics across social networks and can we steer the public opinion to a desired state? Answers to these questions are critically important for understanding the vulnerabilities of online social networks and increasing their resilience to rumor and false information. Recently there has been much ...

Abstract: In multi-class communication networks, traffic surges due to one class of users can significantly degrade the performance for other classes. During these transient periods, it is thus of crucial importance to implement priority mechanisms that conserve the quality of service experienced by the affected classes, while ensuring that the temporarily unstable class is not entirely neglect...

to study the newly mentioned significance of the obstructive lesion morphology in coronary artery disease (cad), a study has been designed to compare this feature between patients having stable angina (sa) or unstable angina (ua) who underwent coronary angiography in tehran heart institute. study objectives were detection of the angina producing artery (ap a) and its morphologic lesion type, de...

These studies deal with analysis and selection of neural networks various architectures hybrid models, which include networks, to predict the market value shares in stock a country that is process unstable development. Analysis forecasting such markets cannot be carried out using classical methods. The relevance research topic due need develop software systems implement algorithmic support for ...

In this paper, we revisit the recurrent backpropagation (RBP) algorithm (Almeida, 1987; Pineda, 1987), discuss the conditions under which it applies as well as how to satisfy them in deep neural networks. We show that RBP can be unstable and propose two variants based on conjugate gradient on the normal equations (CG-RBP) and Neumann series (Neumann-RBP). We further investigate the relationship...

A link between a pair of nodes is defined unstable if it is characterized by a packet loss which is not negligible in one or both directions. The presence of unstable links in multihop ad hoc networks is very likely and it depends on several factors (e.g., different transmission capabilities of the devices, interferences caused by additional wireless devices). Their management by the routing pr...
