Christopher L. Chapman, and Seri Lee Aavid Engineering, Inc. Laconia, New Hampshire 03247 Bill L. Schmidt Silicon Graphics Computer Systems Mountainview, California 94039 Comparative thermal tests have been carried out using aluminum heat sinks made with extruded fin, cross-cut rectangular pins, and elliptical shaped pins in low air flow environments. The elliptical pin heat sink was designed t...

The terrestrial biosphere is currently thought to be a significant sink for atmospheric carbon (C). However, the future course of this sink under rising [CO2] and temperature is uncertain. Some contrasting possibilities that have been suggested are: that the sink is currently increasing through CO2 fertilization of plant growth but will decline over the next few decades because of CO2 saturatio...

Subject of this thesis is the theory of unique sink orientations of cubes. Such orientations are suitable to model problems from different areas of combinatorial optimization. In particular, unique sink orientations are closely related to the running time of the simplex algorithm. In the following, we try to answer three main questions: How can optimization problems be translated into the frame...

Ecological communities are typically open to the immigration and emigration of individuals, and also variable through time. In this paper we argue that interesting and potentially important effects arise when one splices together spatial fluxes and temporal variability. The particular system we examine is a sink habitat, where a species faces deterministic extinction but is rescued by recurrent...

Multi-sink wireless sensor networks are recently gaining interest. They have been introduced to overcome the scalability problem arising in single sink network architectures: by increasing the number of sensor nodes, the information collected at a single sink might become excessive with respect to its communication capacity. In this paper, the topologies formed by means of the IEEE 802.15.4 ass...

The GABAergic agonist muscimol is used to inactivate brain regions in order to reveal afferent inputs in isolation. However, muscimol's use in primary auditory cortex (A1) has been questioned on the grounds that it may unintentionally suppress thalamocortical inputs. We tested whether muscimol can preferentially suppress cortical, but not thalamocortical, circuits in urethane-anesthetized mice....

We study the consequences of asymmetric dispersal rates (e.g., due to wind or current) for adaptive evolution in a system of two habitat patches. Asymmetric dispersal rates can lead to overcrowding of the "downstream" habitat, resulting in a source-sink population structure in the absence of intrinsic quality differences between habitats or can even cause an intrinsically better habitat to func...
