BACKGROUND During vertebrate head development, neural crest cells migrate from hindbrain segments to specific branchial arches, where they differentiate into distinct patterns of skeletal structures. The rostrocaudal identity of branchial neural crest cells appears to be specified prior to migration, so it is important that they are targeted to the correct(More)
We present a general analytical model for predicting the reconstructed frame rate of an MPEG stream. Our model captures the temporal relationships between I-, P, and B-frames but is independent of the channel and media characteristics. We derive an adaptive FEC scheme from the general model and verify it by comparing it to the results of a simulation. The(More)
Sjögren's syndrome is a common autoimmune disease (affecting ∼0.7% of European Americans) that typically presents as keratoconjunctivitis sicca and xerostomia. Here we report results of a large-scale association study of Sjögren's syndrome. In addition to strong association within the human leukocyte antigen (HLA) region at 6p21 (Pmeta = 7.65 × 10(-114)),(More)
Abstrad hternet video is emerging as an important mtitimedia ap pHcation area. Video effects are important dernents in conventional video, but they are tiequently used in hternet ~ideo. Current hard~~based video effects proc~sing SG lutions ~e not w~ matched for the ~+abti@ of kternet video (ie., bit rates, packet loss, jitter, etc.). A SO*+ ody solution,(More)
We present a new representation for image-based interactive walk-throughs. The target applications reconstruct a scene from novel viewpoints using samples from a spatial image dataset collected from a plane at eye-level. These datasets consist of pose augmented 2<i>D</i> images and often have a very large number of samples. Our representation exploits(More)
In vertebrates, body musculature originates from somites, whereas head muscles originate from the cranial mesoderm. Neck muscles are located in the transition between these regions. We show that the chick occipital lateral plate mesoderm has myogenic capacity and gives rise to large muscles located in the neck and thorax. We present molecular and genetic(More)

The forelimbs of higher vertebrates are composed of two portions: the appendicular region (stylopod, zeugopod and autopod) and the less prominent proximal girdle elements (scapula and clavicle) that brace the limb to the main trunk axis. We show that the formation of the muscles of the proximal limb occurs through two distinct mechanisms. The more(More)
The design and implementation of a software decoder for MPEG video bitstreams is described. The software has been ported to numerous platforms including PC's, workstations, and mainframe computers. Performance comparisons are given for different bitstreams and platforms including a unique metric devised to compare price/performance across different(More)
— We consider the problem of applying aggregate congestion control to a class of distributed multi-media applications known as Cluster-to-Cluster (C-to-C) applications. Flows in such an application share a common intermediary path that is the primary source of network delay and packet loss. Using the Coordination Protocol (CP) architecture, we show how(More)
