—This paper examines the effectiveness of combining multiple description coding (MDC) and multiple path transport (MPT) for video and image transmission in a multihop mobile radio network. The video and image information is encoded nonhierarchically into multiple descriptions with the following objectives. The received picture quality should be acceptable,(More)
OBJECT Selective treatment of central nervous system (CNS) structures holds therapeutic promise for many neurological disorders, including Parkinson's disease (PD). The ability to inhibit or augment specific neuronal populations within the CNS reliably by using present therapeutic techniques is limited. To overcome this problem, the authors modeled and(More)
OBJECTIVE The availability of non-invasive brain imaging permits the study of normal and abnormal brain development in childhood and adolescence. This paper summarizes current knowledge of brain abnormalities of two conditions, attention deficit hyperactivity disorder (ADHD) and childhood onset schizophrenia (COS), and illustrates how such findings are(More)
— In this letter, we consider the resequencing delay characteristics of a system with two heterogeneous servers serving a single queue with Poisson packet arrivals. An ordered delivery of packets is guaranteed at the receiver, hence packets arriving out of order suffer additional resequencing delay. We introduce the concept of threshold policies with(More)
Preoligodendrocytes have been described in cultures and tissue prints of adult human white matter (Armstrong et al., 1992). To characterize further these precursors of human oligodendrocytes, we have investigated whether they express genes playing a critical role in oligodendrocyte development. In the intact human brain, platelet-derived growth factor(More)
OBJECT Because of the limited penetration of macromolecules across the blood-spinal cord barrier, numerous therapeutic compounds with potential for treating spinal cord disorders cannot be used effectively. The authors have developed a technique to deliver and distribute macromolecules regionally in the spinal cord by using convection in the interstitial(More)
OBJECT Many macromolecules have the potential to enhance recovery after injury and other lesions of the spinal cord, but because of the limited penetration of these compounds across the blood-spinal cord barrier, they cannot be used effectively. To determine if convective delivery could be used in a common animal model to investigate potential therapeutic(More)
This paper motivates the need for the Multiple Path Transport (MPT) of information in a multihop mobile radio network for supporting non-real time applications. Typical applications will need a higher bandwidth/higher reliability connection than that provided by current mobile networks. For supporting these applications a mobile node may need t o set up and(More)

This paper motivates the need for Multiple Path Transport MPT of video and image information in a multihop mobile radio network. The video and image information is encoded non-hierarchically into multiple descriptions MDC with the following objectives. The received picture quality should be acceptable even if only one description is received and every(More)
