We are seeing a record number of newly diagnosed skin cancers worldwide, with the incidence of melanoma increasing at a faster rate than almost all other cancers. As clinicians, we will have, by far, the greatest impact on reducing this incidence through better methods of early detection of melanoma and proven prevention methods and techniques. The medical(More)
A decline in T-cell responses and a switch to memory T-cell predominance occur with aging. We have used the T-cell receptor (TCR) transgenic mouse model to study age-associated changes in T-cell responses that are a consequence of shifts in subset representation versus changes intrinsic to T cells versus changes in the 'aged' microenvironment. We found that(More)
The Federal Aviation Administration's (FAA) Surveillance and Broadcast Services (SBS) Program Office has implemented one of the first enablers of the Next Generation Air Transportation System (NextGen) by installing a ground infrastructure that supports the Automatic Dependent Surveillance-Broadcast (ADS-B) data service. One of the main applications for(More)
In this paper we propose an speaker verification approach by applying low-rank recovery approach under total variability space, which is trained by a modified Gaussian Mixture Modeling (MGMM) with the observation confidence. In this model, we construct UBM mean supervector by MGMM in order to train total variability matrix and obtain i-vectors. Besides, the(More)
We propose a new method to enhance performance of face recognition under varying lightings by applying score-level fusion between global and local Fourier-Mellin Transform (FMT) features based SVM. An optimal method based Particle Swarm Optimization (PSO) is used to find optimal weights to fuse the aforementioned information at score-level. The results on(More)
Methylphenidate is one of the most common pharmaceutical treatments for Attention Deficit Hyperactive Disorder (ADHD). It is also gaining popularity as a cognitive enhancement and recreational substance. The current study assesses the long-term effects of methylphenidate (MPD) on the circadian rhythm activity pattern of adolescent and adult male(More)
In this paper, a new method for the calculation of the observation-confidence value that is applied in the modified adaptive Gaussian mixture model framework is proposed for speaker verification. First, an adaptive version of the multiple low-rank representation method, for which a weighted decomposition that incorporates the prior information regarding the(More)
