The Center for Biostabilization at UC Davis is attempting to stabilize mammalian cells in the dry state. We review here some of the lessons from nature that we have been applying to this enterprise, including the use of trehalose, a disaccharide found at high concentrations in many anhydrobiotic organisms, to stabilize biological structures, both in vitro(More)
Absfract-Group collaboration capabilities have been developed for Internet-based Mars rover mission operations. Internet-based operations enables scientists to participate in daily Mars rover mission operations from their home institutions. Group collaboration enables geographically separated users to collaboratively analyze downlinked data and plan new(More)
The Science Activity Planner (SAP) is the primary science operations tool for the Mars Exploration Rover mission and NASA’s Software of the Year for 2004. SAP utilizes a variety of visualization and planning capabilities to enable the mission operations team to direct the activities of the Spirit and Opportunity rovers. This paper outlines some of the(More)
Effective data visualization is a key part of the discovery process in the era of “big data”. It is the bridge between the quantitative content of the data and human intuition, and thus an essential component of the scientific path from data into knowledge and understanding. Visualization is also essential in the data mining process, directing(More)
Cloud Computing has delivered unprecedented compute capacity to NASA missions at affordable rates. Missions like the Mars Exploration Rovers (MER) and Mars Science Lab (MSL) are enjoying the elasticity that enables them to leverage hundreds, if not thousands, or machines for short durations without making any hardware procurements. In this paper, we(More)
We have developed a new operator interface system for high-DoF articulated robots based on the idea of allowing the operator to extend the robot's actual kinematics with virtual articulations. These virtual links and joints can model both primary task DoF and constraints on whole-robot coordinated motion. Unlike other methods, our approach can be applied to(More)
Using open source software components in a mission-critical project not only can keep the project within budget but can also result in a more robust and flexible tool. When considering an open source component, prospective users should evaluate the project for several characteristics: maturity, longevity, and flexibility. For greatest benefit, the users(More)
Thirty craniopharyngiomas were operated on between 1983 and 1993. Eight patients underwent surgery solely via the transsphenoidal route. None of these had undergone surgery previously. The eight patients were followed up for a period of 120 months (mean 87.5 months). The tumour was removed totally in five and subtotally in three patients. All eight patients(More)
We overview our recent development and testing of the FIDO rover, an advanced technology prototype for long range mobile planetary science. The current rover is capable of semi-autonomously navigating to, and gathering multi-modal science data from widely dispersed rock-soil targets of interest. Commands are input to FIDO through a high-level " web "(More)
The Mars Polar Lander (MPL) mission is the first planetary mission to w e Internet-based distributed ground operations where scientista and engineers cod labornte in daily mission operations f+om multiple geographically distributed locations via the Internet. This paper describes the operations system, the Web Interface for Telescience (WITS), which is used(More)
