This paper proposes an innovative enhancement of the classical Hopfield network algorithm (and potentially its stochastic derivatives) with an “adaptation mechanism” to guide the neural search process towards high-quality solutions for large-scale static optimization problems. Specifically, a novel methodology that employs gradient-descent in the error space to adapt weights and constraint weig...

BACKGROUND Surgical simulation systems can be used to estimate soft tissue deformation during pre- and intra-operative planning. Such systems require a model that can accurately predict the deformation in real time. In this study, we present a back-propagation neural network for predicting three-dimensional (3D) deformation of a phantom that incorporates the anatomy of the male pelvic region, i...

Facilitation and guidance of computer-supported meetings is a well-known activity that can be supported electronically. Various forms of facilitator support have been developed over the years. This paper presents a unique method for meeting guidance for formal, distributed electronic meetings in the form of meeting guides. The method is Web-based and applies the meeting agenda for creation of a...

This field guide is intended to familiarize participants of IGCP 458 with the aspects of the Newark and Hartford rift basins relevant to the non-marine Triassic-Jurassic boundary and its larger context. We will visit 27 stops that illustrate these the basins' range of sedimentary and igneous environments and paleobiological assemblages, focusing on their significance to the understanding of glo...

This article describes a safe and easy method to position a tracheoesophageal catheter correctly. The procedure is carried out under fluoroscopic guidance and requires neither general nor local anesthesia. The only modification necessary was removal of the tip of the hollow rubber catheter, to create an opening through which the guide wire could be passed.

in medicine, there is a rapid development of a knowledge base. medical professionals need to sustain and advance their competence to practice in response to these varieties. so, there is increased interest in self-directed learning methods. study guides can make a major contribution to self-directed learning. this study was carried out to evaluate the effect of study guides on improving self-le...

central venous catheterization (cvc) is a commonly performed procedure for venous access. it is associated with several complications. we report a rare case of extra luminal entrapment of guide wire during cvc placement in right jugular vein. we report a case of 28 years old female patient presented in our emergency with history of entrapped guide wire in right side of neck during cvc. x-ray sh...

Firewall admins and auditors face some tough questions: • Is the firewall really enforcing the corporate security policy? • How will the new admin learn the firewall rules? • We're acquiring company Y. What does their firewall allow?
