Generalised anxiety disorder (GAD) is defined as excessive and uncontrollable worry and anxiety about everyday life situations. It is a chronic disorder, and is associated with substantial somatisation, high rates of comorbid depression and other anxiety disorders, and significant disability. The evidence base for pharmacotherapy and psychotherapy has(More)
In this paper, we propose a visual tracking approach based on 'bag of features' (BoF) algorithm. First we use incremental PCA visual tracking (IVT) in the first few frames and collect image patches randomly sampled within the tracked object region in each frame for constructing the codebook; the tracked object then can be converted to a bag. Second we(More)
A linear blind source separation algorithm based on generalized eigen-equation resolving is presented. Then a nonlinear blind source separation algorithm is proposed by extending the linear source separation algorithm to the nonlinear domain. The received mixing signals are first mapped to high-dimensional kernel feature space, and a feature vector basis(More)
Antipsychotic use is reported to be associated with a higher risk of sudden cardiac death and new users are especially susceptible to that risk. In this study, we focused on the ability of antipsychotics to prolong the QTc interval at the earliest stages of antipsychotic use. We employed a retrospective cohort study design in a naturalistic setting where(More)
In this paper, a new method with impulse spectrum is presented as a more general way for vibration control of the robotic arm of flexible multiple links. An impulse spectrum is directly responsible for basic processions. The multiple ODE of the arm is analyzed as an LTI system fit for superposition due to its dynamically relative constant. The study shows(More)
The target detection algorithm based on Independent Component Analysis (ICA) was proposed. The orthogonal subspace projection operator was used to extract the target endmembers and the initialization mixing matrix of the FastõICA was made up of such endmember vectors. This method could solve the ordering randomicity of independent vectors. In this(More)
