Fluorescence to measure light intensity
Nature Methods, 2023 AbstractDespite the need for quantitative measurements of light intensity across many scientific disciplines, existing technologies for measuring light dose at the sample of a fluorescence microscope cannot simultaneously retrieve light intensity along with spatial distribution over a wide range of wavelengths and intensities.

Perceived importance of components of asynchronous music in circuit training [PDF]
, 2008 This study examined regular exercisers’ perceptions of specific components of music during circuit training. Twenty-four men (38.8 years, s = 11.8 years) and 31 women (32.4 years, s = 9.6 years) completed two questionnaires immediately after a circuit

An Intensity Measure for Seismic Input Energy Demand of Multi-Degree-of-Freedom Systems [PDF]
Civil Engineering Infrastructures Journal, 2018 Nonlinear dynamic analyses are performed to compute the maximum relative input energy per unit mass for 21 multi-degree-of-freedom systems (MDOF) with preselected target fundamental periods of vibration ranging from 0.2 to 4.0 s and 6 target inter-story ...

Intensity measurements in scattering media [PDF]
Sensors and Actuators B: Chemical, 1999 We describe a new method which allows quantitative measurements of fluorescence intensity in highly scattering media. The measurement principle is based on observing the emission from both the fluorophore of interest with a nanosecond decay time and of a reference fluorophore which displays a much longer microsecond lifetime.

Measurement in Intensive Longitudinal Data
Structural Equation Modeling: A Multidisciplinary Journal, 2021 Technological advances have increased the prevalence of intensive longitudinal data as well as statistical techniques appropriate for these data, such as dynamic structural equation modeling (DSEM). Intensive longitudinal designs often investigate constructs related to affect or mood and do so with multiple item scales.

Underground Space, 2023 The selection of optimal intensity measures (IMs) has been recommended for generating the seismic demand models with different probabilities by researchers since the seismic IMs are closely associated with earthquake risks and structural safety. However,

Finite-Frequency SKS Splitting: Measurement and Sensitivity Kernels [PDF]
, 2008 Splitting of SKS waves caused by anisotropy may be analyzed by measuring the splitting intensity, i.e., the amplitude of the transverse signal relative to the radial signal in the SKS time window. This quantity is simply related to structural parameters.

GeosciencesThis article presents the findings of a study on the directionality effect observed in strong motion records. We set out to establish ratios between several seismic intensity measures that depend on sensor orientation (e.g., GMar, Larger) and others that

Perturbation analysis of Poisson processes
, 2014 We consider a Poisson process $\Phi$ on a general phase space. The expectation of a function of $\Phi$ can be considered as a functional of the intensity measure $\lambda$ of $\Phi$. Extending earlier results of Molchanov and Zuyev [Math. Oper. Res.
