Subcellular Composition Based On Light-Element EELS
收藏 引用
Microscopy and Microanalysis 2020年 第S2期3卷 927-928页
作者: R.D. Leapman Biomedical Engineering & Instrumentation Program NCRR National Institutes of Health Bethesda MD 20892.
Recent work on biological electron energy-loss spectroscopy (EELS) in the analytical electron microscope has focused on measuring concentrations of the important elements, calcium and phosphorus. Analysis of the light...

Microscopy and Microanalysis 1998年 第S2期4卷 212-213页
作者: Leapman, R.D. Swyt-Thomas, C.R. Agoston, D.V. Pivovarova, N. Andrews, S.B. Biomedical Engineering & Instrumentation Program DIRS ORS United States Laboratory of Developmental Neurobiology NICHD United States Laboratory of Neurobiology NINDS National Institutes of Health Bethesda 20892 MD United States
In high-resolution biological energy-dispersive x-ray (EDX) microanalysis it is often necessary to measure very low elemental concentrations. As an example, calcium, a physiologically important element, typically occu...

25th International Conference on Miniaturized Systems for Chemistry and Life Sciences, MicroTAS 2021
作者: Markoski, Alex Wong, Ian Y. Borenstein, Jeffrey T. Department of Synthetic Biology and Bio Instrumentation Draper Bioengineering Division CambridgeMA United States School of Engineering Center for Biomedical Engineering Joint Program in Cancer Biology Brown University ProvidenceRI United States
Microfluidic manipulation and perfusion of multicellular spheroids often utilize device geometries with relatively large channels but smaller trapping features, which are tricky to fabricate with robust bonding. Here,... 详细信息

Advances in Laser and Light Spectroscopy to Diagnose Cancer and Other Diseases 1994
作者: Knüttelt, A. Schmitt, J.M. Shayt, M. Knutsont, J.R. Laboratory of Cell Biology NHLBI National Institutes of Health BethesdaMD20892 United States Biomedical Engineering and Instrumentation Program National Institutes of Health BethesdaMD20892 United States
We describe a new optical low-coherence reflectometer (interferometer) for depth profiling and lateral scanning without moving parts which can also be employed as a stationary FT-JR spectrometer. The reflectometer cov... 详细信息

1992 IEEE-SP International Symposium on Time-Frequency and Time-Scale Analysis
作者: Unser, M. Aldroubi, A. Biomedical Engineering and Instrumentation Program National Center for Research Resources National Institutes of Health Bldg. 13 Room 3W13 BethesdaMD20892 United States
We present an extension of the family of BattlefimariB spline wavelet transforms. By relaxing the intra-level orthogonality constraint, we show how to construct generalized polynomial spline scaling functions and wave... 详细信息

Brain Topography 1994年 第3期6卷 185-192页
作者: Wang, Binseng Toro, Camilo Zeffiro, Thomas A. Hallett, Mark Biomedical Engineering and Instrumentation Program National Center for Research Resources and Human Motor Control Section Medical Neurology Branch National Institute of Neurological Disorders and Stroke National Institutes of Health Bethesda 20892 MD United States
We have developed a method for mapping positions on the head, such as anatomical landmarks, electrode locations, and stimulation sites, onto magnetic resonance (MR) images of the head. This method is based on the regi... 详细信息

IEEE Transactions on Pattern Analysis and Machine Intelligence 1993年 第4期15卷 364-379页
作者: M. Unser A. Aldroubi M. Eden Biomedical Engineering and Instrumentation Program National Center for Research Resources National Institutes of Health DHHS Bethesda MD USA
The authors are concerned with the derivation of general methods for the L/sub 2/ approximation of signals by polynomial splines. The main result is that the expansion coefficients of the approximation are obtained by... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: M. Vrhel Chulhee Lee M. Unser Biomedical Engineering and Instrumentation Program National Institutes of Health DHHS Bethesda MD USA
We introduce a fast simple method for computing the real continuous wavelet transform (CWT). The approach achieves O(N) complexity per scale and the filter coefficients can be analytically obtained by a simple integra... 详细信息
