Beyond Words, Without Words, and Finding Words: Responding to the Catastrophe
(The Aims of Argument, 2002-08-01)
Learning from falling.
(Child Dev, 2006-01)
Walkers fall frequently, especially during infancy. Children (15-, 21-, 27-, 33-, and 39-month-olds) and adults were tested in a novel foam pit paradigm to examine age-related changes in the relationship between falling ...
Why walkers slip: shine is not a reliable cue for slippery ground.
(Percept Psychophys, 2006-04)
In a series of four studies, we investigated the visual cues that walkers use to predict slippery ground surfaces and tested whether visual information is reliable for specifying low-friction conditions. In Study 1, 91% ...
Concentrations of ultrafine, fine and PM2.5 particles in three European cities
(ATMOSPHERIC ENVIRONMENT, 2001)
Total number concentrations, number concentrations of ultrafine (0.01-0.1 mum) and accumulation (0.1-0.5 mum) particles, as well as mass concentration of PM2.5 particles and blackness of PM2.5 filters, which is related to ...
An Endowed Peace
(Museum Helveticum, 2004)
Comparison of pattern detection methods in microarray time series of the segmentation clock.
(PLoS One, 2008-08-06)
While genome-wide gene expression data are generated at an increasing rate, the repertoire of approaches for pattern discovery in these data is still limited. Identifying subtle patterns of interest in large amounts of data ...
Labour and NAFTA: Nationalist Reflexes and Transnational Imperatives in North America, 1991-1995
(Labour and Globalisation, 2004)
Clinical assessment and characterization of a dual tube kilovoltage X-ray localization system in the radiotherapy treatment room.
(Journal of applied clinical medical physics, 2008-01-13)
INTRODUCTION:Although flat-panel based X-ray imaging has been well tested in diagnostic radiology, its use as an image-guided-radiotherapy (IGRT) system in a treatment room is new and requires systematic assessment. MATERIALS ...
The application of distance transformation on parameter optimization of inverse planning in intensity-modulated radiation therapy.
(Journal of applied clinical medical physics, 2008-04-16)
In inverse planning for intensity-modulated radiation therapy (IMRT), the dose specification and related weighting factor of an objective function for involved organs is usually predefined by a single value and then iteratively ...
A positioning QA procedure for 2D/2D (kV/MV) and 3D/3D (CT/CBCT) image matching for radiotherapy patient setup.
(Journal of applied clinical medical physics, 2009-10-06)
A positioning QA procedure for Varian's 2D/2D (kV/MV) and 3D/3D (planCT/CBCT) matching was developed. The procedure was to check: (1) the coincidence of on-board imager (OBI), portal imager (PI), and cone beam CT (CBCT)'s ...
