This paper reviews and compares individual voxel-wise thresholding methods for identifying active voxels in single-subject fMRI datasets. Different error rates are described which may be used to calibrate activation thresholds. We discuss methods which control each of the error rates at a prespecified level alpha, including simple procedures which ignore spatial correlation among the test stati...

A stationary pattern with asymmetrical luminance gradients can appear to move. We hypothesized that the source signal of this illusion originates in retinal image motions due to fixational eye movements. We investigated the inter-subject correlation between fixation instability and illusion strength. First, we demonstrated that the strength of the illusion can be quantified by the nulling techn...

We discuss the possible detection of a stochastic background of massive, nonrelativistic scalar particles, through the cross correlation of the two LIGO interferometers in the initial, enhanced and advanced configuration. If the frequency corresponding to the mass of the scalar field lies in the detector sensitivity band, and the non-relativistic branch of the spectrum gives a significant contr...

HIV (Human Immunodeficiency Virus) researchers are often concerned with the correlation between HIV viral load measurements and CD4+ lymphocyte counts. Due to the lower limits of detection (LOD) of the available assays, HIV viral load measurements are subject to left-censoring. Motivated by these considerations, the maximum likelihood (ML) method under normality assumptions was recently propose...

Recently, local correlation tracking has been applied to magnetograms for determining photospheric velocities. This letter demonstrates that local correlation tracking is inconsistent with the magnetic induction equation which governs the temporal evolution of the photospheric magnetograms. A modified formulation, consistent with the magnetic induction equation, is presented for accurately foll...

The spatio-temporal correlation of natural images during fixational eye instability is studied. The statistics of eye movements and static natural images are first analyzed separately and then combined to obtain an analytical formula for the correlation function. Previous work on this subject is presented and important shortcomings are pointed out. A more rigorous and general formula is derived...

We review several inequalities concerning Gaussian measures isoperimetric inequality, Ehrhard’s inequality, Bobkov’s inequality, S-inequality and correlation conjecture. 2000 Mathematics Subject Classification: 60E15, 60G15, 28C20, 26D15.

Recently digital forensics has become a prominent activity in crime investigation since computers are increasingly used as tools to commit crimes. During forensic investigation the digital devices such as desktops, notebooks, smart phones etc. found at the crime scene are collected for further investigation. Investigators have to go through humongous amount of data stored on these devices to ga...

In this paper, correlation between rock types and Cu mineralization obtained by Concentration-Number (C-N) fractal model calculated in Kushk-e-Bahram Cu deposit, Central Iran. This deposit is located in the Urumieh-Dokhtar magmatic arc (UDMA). The main subject in this study was determination of relation between the Cu grade populations and rock types based on subsurface data using logratio matr...
