To estimate conduction velocities from activation times in myocardial tissue, the "average vector" method computes all the local activation directions and velocities from local activation times and estimates the fastest and slowest propagation speed from these local values. The "single vector" method uses areas of apparent uniform elliptical spread of activation and chooses a single vector for ...

We estimate the number of CdSe quantum dots QDs in a microenvironment by analyzing the intensity fluctuation of the fluorescence time trace from a collection of QDs in the fluorescence intensity steady-state regime. The steady state is chosen because the aged blinking dynamics of single QDs leads to a higher probability for observing large on and off waiting times relative to the typical time b...

We analyze the approximation behavior of some of the best-known polynomial-time approximation algorithms for bin-packing under an approximation criterion, called differential ratio, informally the ratio (n − λ(I))/(n − β(I)), where n is the size of the input list, λ(I) is the size of the solution provided by an approximation algorithm and β(I) is the size of the optimal one. This measure has or...

To calculate the RDF, for each time frame we used the centers of the neurofilaments in the domain [−0.2μm, 0.2μm] × [−0.2μm, 0.2μm] as reference points. We chose to use reference points in a smaller domain in order to avoid boundary effects. For each reference point we binned the center-to-center distances (r) between the reference neurofilament and all other neurofilaments with a bin size ∆r =...

With the trend of cellular providers shifting to higher frequencies, there is an increasing migration to smaller cells that is further driven by the growing demand for wireless Internet service. This obviously calls for higher resolution Radio Frequency (RF) validation and prediction. Yet, to our knowledge, there has been no study as to what resolution is required for accurate RF modeling and p...

Speech coding forms a crucial element in speech communications. An important area concerning it lies in feature extraction which can be used for analyzing Hindustani Classical Music. An important feature in this respect is the fundamental frequency often referred to as the pitch. In this work, the terms pitch and its acoustical sensation, the frequency is used interchangeably. There exists nume...
