Introduction: A challenge in lateralization index (LI) of functional magnetic resonance imaging (fMRI) lies in ensuring how to compute LI reasonably. Conventional LI sets a t-value threshold to calculate “Left–Right/Left+Right” where Left and Right are suprathreshold voxel numbers or summations of t-values of a pair of regions of interest (ROIs) in left and right hemispheres. In reality, the LI...

the zarankiewicz number z(b; s) is the maximum size of a subgraph of kb,b which does not contain ks,s as a subgraph. the two-color bipartite ramsey number b(s, t) is the smallest integer b such that any coloring of the edges of kb,b with two colors contains a ks,s in the rst color or a kt,t in the second color.in this work, we design and exploit a computational method for bounding and computin...

In order to increase the resolution, we first utilize FMCW to separate signals reflected off from different distances into voxels, so each voxel stands for signal reflected off from a specific distance from the transmitter. Once we have a voxel of interest, we can zoom-in the specific voxel, and analyze the phase shift in that voxel to determine relative movements within that voxel. Figure 1 il...

data obtained in association with many real-life random experiments from different fields cannot be perfectly/exactly quantified.hspace{.1cm}often the underlying imprecision can be suitably described in terms of fuzzy numbers/values. for these random experiments, the scale of fuzzy numbers/values enables to capture more variability and subjectivity than that of categorical data, and more accura...

in this paper, by using a new approach on distance between two fuzzy numbers, we construct a new ranking system for fuzzy number which is very realistic and also matching our intuition as the crisp ranking system on r.

introduction: conventional methods for diagnosis of external root resorption (err) are based on clinical findings and x-ray observations which are not appropriate for early diagnosis. the present study assessed the effect of different sizes and field of views (fovs) in the diagnosis of simulated external root resorption by cone-beam computed tomography (cbct). methods and materials: in this dia...
