In the present study, post inflammation irritable bowel syndrome (PI-IBS) rats were firstly established by intracolonic instillation of acetic acid with restraint stress. Then the pharmacokinetics of berberine in the rat plasma were compared after oral administration of berberine hydrochloride (25 mg/kg) to normal rats and PI-IBS rats. Quantification of(More)
This brief deals with the problem of minor component analysis (MCA). Artificial neural networks can be exploited to achieve the task of MCA. Recent research works show that convergence of neural networks based MCA algorithms can be guaranteed if the learning rates are less than certain thresholds. However, the computation of these thresholds needs(More)
Researches on neural population coding have revealed that continuous stimuli, such as orientation, moving direction, and the spatial location of objects could be encoded as continuous attractors in neural networks. The dynamical behaviors of continuous attractors are interesting properties of recurrent neural networks. This paper proposes a class of(More)
In the mobile Internet era, people not only have more opportunities to appreciate and use a large number of electronic images of paintings, but can also make use of computers and networks to create abstract artistic pictures. Starting from the principle of abstract pictures, this paper describes the design of a web-based platform on which ordinary users can(More)
Regularized linear regression based representation techniques for face recognition (FR) have attracted a lot of attention in past years. The l<sub>1</sub>-regularized sparse representation based classification (SRC) method achieves state-of-the-art results in FR. However, recently several studies have shown the role of collaborative representation (CR) that(More)
Residual classifiers are common in dictionary-based multiclass classification. This paper proposes the concept of performance functions for residual classifiers. A performance function for multiclass classifications is a conceptual measurement function that combines local and global measurements. In general, the performance function is nonlinear. To explore(More)
By analysis of working principle of elastic steel plate type load moment limiter, the nonlinear relation between the load moment and the horizontal displacement of moment limiter is indicated. This paper proposes a soft-sensing model based on functional link neural network (FLNN) with the horizontal displacement of moment limiter as input and the load(More)
Continuous attractors of recurrent neural networks (RNNs) have attracted extensive interests in recent years. It is often used to describe the encoding of continuous stimuli such as orientation, moving direction and spatial location of objects. This paper studies the dynamic shift mechanism of a class of continuous attractor neural networks. It shows that(More)
