Identifying and evaluating functionally connected regions in the brain has become a challenging problem to solve in many studies of neurological and psychiatric disorders. In particular, functional connectivity of brain mechanisms underlying disturbed cognition in depression is still not well understood in current neuroscience research. Based on the Stroop paradigm, specifically, the face-word Stroop...
Classification of Alzheimer 's disease (AD) from normal control (NC) is important for disease abnormality identification and intervention. The current study focused on distinguishing AD from NC based on the multi-feature kernel supervised within- class-similarity discriminative dictionary learning algorithm (MKSCDDL) we introduced previously, which has been derived outperformance in face recognition...
Depression is a mental disorder of high prevalence, leading to a negative effect on individuals, their families, society and the economy. In recent years, the problem of automatic detection of depression from the speech signal has gained more interest. In this paper, a new multiple classifier system for depression recognition was developed and tested. The novel aspect of this methodology is the combination...
In this paper, an advanced multiple input multiple output (MIMO) SAR algorithm for high-resolution three-dimensional reconstruction imaging was proposed. Firstly, we give a short overview of the principle of scattering mechanism and the formulations of optimized physical optics (PO). Additionally, a three-dimensional(3D) MIMO SAR array is illustrated. Finally, NVIDIA's Compute Unified Device Architecture...
Many neuroscience studies have found brain differences lead to the gender differences in behavior and cognitive ability. Functional connectivity is a common and effective measure to characterize brain. Most current studies based on fMRI functional connectivity basically assumed temporal stationarity across the duration of scanning, and thought that brain functional connectivity was constant in a certain...

In this paper, based on electromagnetic (EM) scattering theory, we present a target detection system in sea clutter working with simulated Synthetic Aperture Radar (SAR) images. A numerical case CVN-76 aircraft carrier was computed by using multilevel fast multipole algorithm (MLFMA). And the Fung and Lee sea-spectrum model was employed for three-dimensional wind driven ocean spectrum. Co-polarization...
A systematic synthesis approach for floating gyrators employing single z-copy current-controlled current conveyor trans-conductance amplifier (CCCCTA) is presented in this work. Initially, the pathological models of two types of the CCCCTA, namely z-copy z+-output CCCCTA (CCCCTA+) and z-copy z−-output CCCCTA (z-copy CCCCTA−), are derived by virtue of the nodal admittance matrix (NAM) expansion method...
With the rapid emergence of mobile devices, smart phones have penetrated into every aspect of people's daily life.

In a cognitive radio network (CRN), when the secondary users (SUs) are battery-powered devices, the concept of energy-efficient design is very important. In this paper, we propose an energy utility function by formulating the achievable data rate of a cooperative CRN in terms of the energy consumption by the CRN. The maximization of the energy utility function is obtained by jointly designing the...
In this paper, we consider a joint optimization of sensing parameter and power allocation for an energy-efficient cognitive radio network (CRN) in which the primary user (PU) is protected.
