The applicability of the [14C]deoxyglucose method for measuring local cerebral glucose utilization (lCMRglc) has been extended for use in hypoglycemia by determination of the values of the lumped constant to be used in rats with plasma glucose concentrations ranging from approximately 2 to 6 mM. Lumped constant values were higher in hypoglycemia and declined from a value of 1.2 at the lowest ar...

The response of back-supported buffer plates comprising a solid face sheet and foam core backing impacted by a column of high velocity particles (sand slug) is investigated via a lumped parameter model and coupled discrete/continuum simulations. The buffer plate is either resting on (unattached) or attached to a rigid stationary foundation. The lumped parameter model is used to construct maps o...

In performance-driven interconnect design, delay estimators are used to determine both the topol-ogy and the layout of good routing trees. We address the class of moment-matching methods used to model distributed RLC interconnects with a small number of lumped segment models. We provide new non-uniform segment models which match the transfer function of a general interconnect line with source a...

Phase 2 of the Distributed Model Intercomparison Project (DMIP 2) was formulated primarily as a mechanism to help guide the US National Weather Service (NWS) as it expands its use of spatially distributed watershed models for operational river, flash flood, and water resources forecasting. The overall purpose of DMIP 2 was to test many distributed models with operational quality data with a vie...

A condensed version of the SAPRC-07 mechanism (Carter, 2008) was implemented in a 3-D air quality model and applied to the Los Angeles area as part of the present review. The CIT airshed model was used; see Martien et al. (2003 and 2006) for description of model input data. The summer 1997 emission inventory was used here. Martien et al. used an extended version of SAPRC-99 that had many indivi...
