The mantle plume underlying the Hawaiian Swell has been modelled numerically using a stationary steady axisymmetric plume under a solid conducting lid. A method of calculating the rate of melt production from the plume has been developed, and the total melt production rate, the residual depth anomaly and the geoid anomaly have been used to constrain the model. The plume has a central potential ...

The proto-oncogene c-fos was transiently upregulated in primitive hematopoietic stem (Lin-Sca-1(+)) cells stimulated with stem cell factor, interleukin-3 (IL-3), and IL-6. To investigate a role of the c-fos in hematopoietic stem cells, we used bone marrow (BM) cells from transgenic mice carrying the c-fos gene under the control of the interferon-alpha/beta-inducible Mx-promoter (Mx-c-fos), and ...

Formation of mesoderm from the pluripotent epiblast depends upon canonical Wnt/beta-catenin signaling, although a precise molecular basis for this requirement has not been established. To develop a robust model of this developmental transition, we examined the role of Wnt signaling during the analogous stage of embryonic stem cell differentiation. We show that the kinetics of Wnt ligand express...

The high bandwidth required by live streaming video greatly limits the number of clients that can be served by a source. In this work, we discuss and evaluate an architecture, called SpreadIt, for streaming live media over a network of clients, using the resources of the clients themselves. Using SpreadIt, we can distribute bandwidth requirements over the network. The key challenge is to allow ...

ly, let M be the number of copies of a single multicast that a member receives from the lower dissemination layer. For the Pbcast implementation, since each member gossips a given multicast for O(log(n)) gossip rounds and to randomly chosen targets, we have M = O(log(n)). To maximize the throughput, one would want to minimize the number of copies M of a multicast that a member receives from the...

one of the most important characteristics of the eternal religion is the adaptation of its decrees with the changes of the human’s life in the transition of time. so, it is necessary for us to review the second decrees as the flexible dimensions of the decrees. according to the causes of some decrees’ change, altering the decree’s subject leads to the change of the primitive decrees into the se...

Urodeles begin gastrulation with much of their presumptive mesoderm in the superficial cell layer, all of which must move into the deep layers during development. We studied the morphogenesis of superficial mesoderm in the urodeles Ambystoma maculatum, Ambystoma mexicanum, and Taricha granulosa. In all three species, somitic, lateral, and ventral mesoderm move into the deep layer during gastrul...

A one-layer, mid-latitudeJ beta-plane channel model of an incompressible homogeneous fluid is constructed to study the propagation of systematic errors on a nearly stationary synoptic scale wave. A timeand space-centered difference scheme is used to evaluate the governing primitive equations. Data fields resulting from height field perturbations injected at various locations in the synoptic wav...
