The study on the Cell Survival for Bio Artificial Liver by using standardisation Extracorporeal Circulation Method
by Seonghwan Kim, Minwoo Cheon
Abstract: The only way to replace an already-impaired liver is a liver transplantation or artificial liver functioning as a liver. This research is on the standardization of perfusion to help increase the survival rate of hepatic insufficiency patients through the enhanced cell survival of artificial livers. Generally, artificial livers are used in the form of extracorporeal circulation with a mounted bioreactor. As artificial livers need to replace liver functions, to enhance the liver cell survival ratio in the bioreactor, the bioreactor performance needs to be improved. To this end, perfusion standardization is required in the extracorporeal circulation and each circulation pumps should be interoperable. In this recognition, this study looked at possible standardization of perfusion methods capable of increasing liver cell survival rate in order to find out the optimal standardized bio-reactor. As a result, perfusion 2 control was found to be essential in raising the cell survival ratio and perfusion 3 implementation enhanced the survival ratio.

A New Embedded Image Compression Scheme using Rate-Distortion Optimized Block Coding of Wavelet Coefficients
by Chang Mo Yang, Kwangsue Chung
Abstract: In this paper, we propose a new embedded image compression scheme which uses rate-distortion optimized block coding of wavelet coefficients. Unlike conventional embedded compression schemes which use the set partition or block partition coding methods according to the magnitude of wavelet coefficients, the proposed scheme achieves rate-distortion optimization by ordering wavelet coefficients or blocks according to their expected rate-distortion slopes. In addition, the proposed scheme uses a modified block partition method, and new context models for the entropy coding. Experimental results demonstrate that the proposed scheme not only produces embedded bit-streams, but also outperforms existing embedded compression schemes.
Keywords: Block Partition Coding; Embedded Image Compression; Rate-Distortion Optimization; RDBC; Wavelet.
Is smartphone creating a better life? Exploring the relationships of the smartphone practices,social capital and psychological well-being among college students
by Hua Pang
Abstract: Along with the development of wireless communication and the rapid diffusion of handset, mobile technologies have provided individuals with unprecedented new spaces for social interactions and multiple modes of expression, and as such, they are expected to enhance individuals social capital as well as psychological well-being. This empirical study investigates the relationship between the utilization of smartphones and social capitals formation and maintenance with an emphasis on youth uses and practices. In addition to assessing bonding and bridging social capital, it also explores maintained social capital by evaluating how mobile communication influences ones individual capability to keep in touch with members of a formerly inhabited community. The results from a survey of college students (N = 346) demonstrate a strong linkage between smartphone use and three different modes of social capital. And the strongest relationship, revealed by Pearson correlation coefficient analysis, is between smartphone use and bridging social capital. However, the present study did not find evidence that the intensity of smartphone usage predicts two measures of psychological well-being including self-esteem and life satisfaction. Limitations and suggestions for future research are discussed.

A Semi-Supervised Locally Linear Embedding Spectral Clustering Algorithm
by Wu Xi
Abstract: Many practical problems can be attributed to the clustering problem. Spectral clustering algorithm is a method based on graph theory. Compared with the traditional clustering algorithm, it can be clustered in any shape of space, and obtain the global optimal solution. Based on the classical NJW algorithm, utilizing the supervision information to guide the clustering process, the result of clustering is more accurate. Meanwhile, combined the manifold learning with semi-supervised spectral clustering algorithm, and r the datas dimension will reduce based on locally linear embedding. LLE method is a non-linear dimension reduction method. Based on the heuristic thinking, calculated distance matrix, a reasonable number of nearest neighbors could be funded, thus we achieve the purpose of dimension reduction. Moreover, clustering based on reduced dimension data, the same clustering results as the original data could be obtained. The proposed algorithm insures high correctness and improves the running speed, and reduces the overhead of computation. Experimental results have shown that this algorithm could achieve better clustering effect on artificial data sets and real data sets.

Sparsity constrained model for the semantic features
by Weihua Ou, Wenjun Xiao
Abstract: Predicting brain activity associated with concrete concepts has been
attracted wide attention in brain imaging studies. The main task is to construct
computational model for the link between the stimuli and the brain image. In
the model, the neural basis of the concepts are revealed by their co-occurrences
with 25 basic verbs in a large text corpus. However, the ordinary regression
model cannot make the desired selection among the semantic features due to
the small sample size problem. In this paper, we propose a sparsity constrained
model to automatically choose the relevant semantic features. Specifically, we
explicitly constrain the number of semantic features associatedwith the individual
voxels. The motivation is based on the fact that the responses of a voxel to the
stimuli can only be explained by a limited number of neuron activity bases. The
experimental results on predicting brain images show the effectiveness of the
proposed approach, as well as meaningful representation of the concepts.

Structured sparsity model with spatial similarity regularization for semantic feature selection
by Weihua Ou, Wenjun Xiao
Abstract: In the brain function studies, it has been widely attracted attention to predict brain activity associated with concrete concepts. The main task is to construct computational model to real the neural basis of the concepts by their co-occurrence with 25 basic verbs in a large text corpus. However, the ordinary regressionmodel cannot select desired semantic features and easily over-fitswhen the number of observations is small relative to the size of the candidate semantic features. To address these problems, in this paper,we propose a structured sparsity model to automatically choose the relevant semantic features by exploiting the sparsity of responses and the spatial relationships between the voxels. Specifically, we require the number of the non-zero responses to be sparse and the responses that two voxels are nearby in the brain to be similar. These are based on the facts that each voxel in the brain is only involved in limited semantic bases and the voxels are spatially neighbor, respectively. The constraints do not only regularize the model fitting, but also have interpretation in terms of brain hemodynamics. The experimental results on predicting brain images show the effectiveness of the proposed approach, as well as improved interpretability.
