Multidimensional Dyspnea Profile: an instrument for clinical and laboratory research
There is growing awareness that dyspnoea, like pain, is a multidimensional experience, but measurement instruments have not kept pace. The Multidimensional Dyspnea Profile (MDP) assesses overall breathing discomfort, sensory qualities, and emotional responses in laboratory and clinical settings. Here we provide the MDP, review published evidence regarding its measurement properties and discuss ...
متن کاملIMS-IMS and IMS-IMS-IMS/MS for separating peptide and protein fragment ions.
Multidimensional ion mobility spectrometry (IMS-IMS and IMS-IMS-IMS) techniques have been combined with mass spectrometry (MS) and investigated as a means of generating and separating peptide and protein fragment ions. When fragments are generated inside a drift tube and then dispersed by IMS prior to MS analysis, it is possible to observe many features that are not apparent from MS analysis al...
متن کاملExploratory Longitudinal Profile Analysis via Multidimensional Scaling - Practical Assessment, Research & Evaluation
Studying change processes in education and the behavioral sciences has been of interest for a long time. Researchers and practitioners in the behavioral sciences are concerned with questions about how individuals change over time (Willett & Sayer, 1994; Williamson, Appelbaum, & Epanchin, 1991). That is, we are interested in the question of how individual change in certain attributes (for exampl...
متن کاملKnowledge Systematization in the International IMS Research Program
The international Intelligent Manufacturing Systems (IMS) research program is an attempt to systematize and make operational world-wide knowledge of advanced manufacturing systems as a basis for new paradigms. This paper gives an overview of the IMS objectives, the six test cases to date, and the proposed future research activities. It describes the coordination of the IMS GNOSIS test case, con...
متن کاملAn IMS-IMS analogue of MS-MS.
The development of a new ion mobility/mass spectrometry instrument that incorporates a multifield drift tube/ion funnel design is described. In this instrument, individual components from a mixture of ions can be resolved and selected on the basis of mobility differences prior to collisional activation inside the drift tube. The fragment ions that are produced can be dispersed again in a second...
