AIMS Goblet cell carcinoid is a poorly understood tumour of the appendix. The aim of this study was to determine whether it should be regarded as a separate entity or as a variant of classical carcinoid. METHODS AND RESULTS The immunohistochemical expression pattern of 21 markers and the mutation status of KRas codon 12 were determined in 16 goblet cell(More)
In this paper, we summarize an approach for the dissemination of robotics technologies. In a manner analogous to the personal computer movement of the early 1980’s, we propose that a productive niche for robotic technologies is as a long-term creative outlet for human expression and discovery. To this end, this paper describes our ongoing efforts to design,(More)

Installation of a robot system in a publicly accessible technical museum poses nontrivial problems along three axes. First, the robot must be reliable, both by failing rarely in spite of continuous, daily use and by allowing museum staff to easily return the robot to service. Second, the robot must perform without the need for staff intervention, from(More)
Robotics brings together learning across mechanism, computation and interaction using the compelling model of real-time interaction with a physically instantiated intelligent device. The project described here is the third stage of the Personal Rover Project, which aims to produce technology, curriculum and evaluation techniques for use with after-school,(More)

There are numerous ways to address nonresponse bias adjustment in surveys; two such methods are calibration weighting and propensity score models. Calibration is a viable technique when good external benchmarks exist; however, good external benchmarks are not always available. An alternative method to calibration is to use propensity scores to adjust for(More)
