The Cascade Range is a geothermal dichotomy. On the one hand, it is an active volcanic arc above a subducting plate and is demonstrably an area of high heat flow. On the other hand, the distribution of hydrothermal manifestations compared to other volcanic arcs is sparse, and the hydrothermal outflow calculated from stream chemistry is low. Several large estimates of undiscovered geothermal res...

Serializer/deserializer (SerDes) transceivers are an increasingly popular way to reduce IC pin-count, power, electromagnetic interference, and wiring between ICs. Mainstream serial data rates are around 2.5 Gbps, with PCI-Express being the most common standard, but 5 to 10 Gbps SerDes I/Os are in many new designs. The total number of such transceivers shipped (there may be many per IC) is expec...

Disease relapse and transplant related toxicities have limited the application of bone marrow transplantation (BMT) in the treatment for hematologic malignancies. Because elevated levels of tumor necrosis factor alpha (TNF-a) have been correlated with the development of transplant related complications, we conducted a phase 1-11 trial of pentoxifylline (PTX), a xanthine derivative capable of do...

We give a correction to the tunneling probability by taking into account the back reaction effect to the metric of the black hole spacetime. We then show how this gives rise to the modifications in the semiclassical black hole entropy and Hawking temperature. Finally, we reproduce the familiar logarithmic correction to the Bekenstein-Hawking area law. In 1975, Hawking discovered [1] the remarka...

We consider quantum mechanical corrections to a homogeneous, isotropic and spatially flat geometry whose scale factor expands classically as a general power of the co-moving time. The effects of both gravitons and the scalar inflaton are computed at one loop using the manifestly causal formalism of Schwinger [1] with the Feynman rules recently developed by Iliopoulos et al. [2]. We find no sign...

Recent data from positron emission tomography (PET) imaging studies suggest the possibility of studying synaptic transmission in vivo in humans. The approach will require a synthesis of two established techniques: brain activation studies (conventionally performed by measuring regional cerebral blood flow or metabolism) and neurotransmitter receptor imaging (using radiolabelled ligands that bin...

ExEcutIvE Summary In this chapter, I propose a comprehensive study of erbium-doped fiber amplifier (EDFA) and erbium doped fiber laser (EDFL). The chapter is based on three principal levels: the first is at the atomic level, where it is evident and meaningful to give general and deep studies on erbium spectra at theoretical background angle. The important part that needs to be understood in the...

1: This document describes a control-plane network design for general scalable GMPLS networks. We use the Circuit-Switched High-speed End-to-End ArcHitecture (CHEETAH) network as an example to illustrate how we implemented our design. The CHEETAH network is a Synchronous Optical NETwork (SONET) based network that uses Sycamore SN16000 switches. While some of the specifics related to this switch...

The advent of terabit aggregate rate telecommunication devices and multi-gigahertz I/O interfaces is posing new challenges on the semiconductor and ATE industries. Telecom chipmakers are currently using ad hoc techniques to test these kinds of devices due to the lack of a credible commercial solution. This session highlights the challenges of testing multi-gigahertz interfaces and presents prom...

Portland cements are used to immobilize low-level radioactive wastes and have several advantages over other matrix materials. They are tolerant of wet wastes, are nonflammable and inert and have a well proved process technology. Moreover. they are reasonably durable in underground repositories and, of course, are compatible with concrete vaults, backfills, etc. The short-term immobilization pot...
