Cardiotrophin-1 (CT-1) is a cytokine involved in the growth and survival of cardiac cells via activation of the Janus activated kinase/signal transducer activator of transcription (JAK/STAT). Statins, 3-Hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors, have effects that extend beyond cholesterol reduction and inhibit vascular smooth muscle(More)
This paper presents a feature selection approach for handwritten similar Chinese characters recognition. The optimal features can be selected automatically by genetic algorithms from the representations in the form of elastic meshing based on wavelet transform. Three different combinations of binary support vector machines classifiers are discussed when(More)
Different from the traditional age estimation systems, this paper introduces a novel method to estimate human age from facial images combined with non-fixed age group classification and Rank-based age value estimation. The basic idea is to use the continuous and ordinal information from human facial aging process. Firstly, pair-wise distance classifiers are(More)
OBJECTIVE To investigate the relationship between the plasma macrophage migration inhibitory factor (MIF), activator protein-1 (AP-1) and MMP-9 concentrations and the severity of coronary artery lesions in coronary heart disease (CHD) patients. METHODS Patients were divided into normal controls (n = 35), stable angina pectoris (SAP, n = 32) and acute(More)
Discrete orthogonal moment set is one of the novel feature moment-based descriptors for image analysis. The Tchebichef moments and Krawtchouk moments are the two representatives in this class. This paper studies the performance of the two discrete orthogonal moments in the recognition of off-line handwritten Chinese amount in words under discrete-time(More)
This paper divides the typical social scientific research process into two stages: the research development stage and the research innovation stage, with personnel as a shared input between them. We construct an input-shared multi-period two-stage DEA (data envelopment analysis) model as measurement of sustainability capacities of social scientific(More)
This paper proposes a new efficient approach using the set of Krawtchouk moments and HMM for character recognition. The Krawtchouk moments set is a new set of orthogonal moments based on the discrete classical Krawtchouk polynomials. Compared to continuous moments such as geometric, Hu invariants, Zernike and Legendre moments, the implementation of(More)
This paper proposes an approach combining the set of Krawtchouk moments and HMMs (hidden Markov models) for unconstrained offline handwritten Chinese character recognition. The Krawtchouk moments can be effectively used as pattern features in analysis of two-dimensional images. Since the basis set is orthogonal in the discrete domain of the image coordinate(More)
Endothelial dysfunction is associated with cardiovascular diseases. The Ca(2+) influx occurring via activation of plasmalemma Ca(2+) channels was shown to be critical in signaling the increase in endothelial permeability in response to a variety of permeability-increasing mediators. It has been reported that angiotensin II (AngII) could induce Ca(2+)(More)
