I develop an asset-pricing model in which financial assets are valued for their liquidity– the extent to which they are useful in facilitating exchange–as well as for being claims to streams of consumption goods. The implications for average asset returns, the equitypremium puzzle, and the risk-free rate puzzle, are explored both analytically and quantitatively in a version of the model that ne...

(m, k)-firm real-time or weakly hard real-time (WHRT) guarantee is becoming attractive as it closes the gap between hard and soft (or probabilistic) real-time guarantee, and enables finer granularity of real-time QoS through adjusting m and k. For multiple streams with (m, k)-firm constraint sharing a single server, an on-line priority assignment policy based on the most recent k-length history...

Backup utilities for the Windows environment are designed to work with the NTFS file format, but they typically provide only partial compatibility with Alternate Data Streams (ADSs). In particular, computer forensics tools are typically capable of discovering ADSs in the file system under investigation, but not necessarily in the backups of such file systems. We examined a number of commonly us...

For over six million years, salmon and steelhead (known as salmonids) have returned to the California Central Valley. After swimming under Golden Gate Bridge through San Francisco Bay, adult salmonids swim hundreds of miles up Sacramento or Joaquin Rivers. Before dams were built, three out five salmonid species swam from Valley into high-elevation, cold-water streams within Sierra Nevada, south...

From 1985 to 1988, stream and riparian habitats in Pen branch and Four Mile branch began recovering from deforestation caused by the previous release of hot water from nuclear reactors. The Pen branch corridor was replanted with wetland trees in 1995 to expedite recovery and restore the Pen branch ecosystem. Pen branch, Four Mile branch, and two relatively undisturbed streams were electrofished...

We studied the high energy quark anti-quark elastic scattering with an exchange of a mesonic state in the t channel with −t/Λ 2 QCD 1. Two methods are proposed to eliminate the strong background from bare pomeron, reggized gluon and odderon exchange. The feasibility of measuring mesonic reggeon exchange is discussed.

Policy analyses frequently clash. Their disagreements stem from many sources, including models, empirical estimates, and values such as who should have standing and how different criteria should be weighted. We provide a simple taxonomy of disagreement, identifying distinct categories within both the positive and values domains of normative policy analysis. Using disagreements in climate policy...
