Major challenges confronting marine biogeochemical modeling

Substantial improvements are required in the current suite of numerical models if we are to better understand the present ocean biogeochemical state and predict potential future responses to anthropogenic perturbations. At present, major impediments to marine biogeochemical modeling include the inadequate representation of multi-element cycling and community structure, large-scale physical circ...

New directions in research bring new clinical challenges.

Charles H. Dankmeyer Jr, CPO Sputnik! On October 4th, 1957, Russia launched the first satellite into successful space orbit. I was 13 years old and remember how that event rocked America. Between playing ball and riding bicycles, my friends and I were enjoying the pleasure of watching the older boys hot rod their old Fords and Chevys. Listening to the sweet sounds of Hollywood pipes sing their ...

New Perspectives on Biogeochemical Exploration

Significant refinements of biogeochemical methods applied to mineral exploration have been made over the past quarter century, with advances on all continents. Databases from surveys around the world provide enhanced information on which species and tissues to collect from all major climatic environments, and how, why and when to sample. Recent commercialization of sophisticated new ICPMS analy...

New HDL Research Challenges posed by Dynamically

Dynamically re-programmable hardware (e.g. Field Programmable Gate Arrays or FPGAs) change many of our basic assumptions of what hardware is. Normal hardware design focuses on the development of a static circuit of xed size, topology and functionality. The static nature of the target design entity is re ected in the design of CAD tools, hardware description languages, net-list representations a...

Broad New OS Research: Challenges and Opportunities

Contemporary software systems are beset by problems that create challenges and opportunities for broad new OS research. To illustrate, we describe five areas where broad OS research could significantly improve the current user experience. These areas are dependability, security, system configuration, system extension, and multi-processor programming. In each area we explore how contemporary sys...
