At present, typical approaches employed to repair fractures and other bone lesions tend to use matrix grafts to promote tissue regeneration. These grafts act as templates, which promote cellular adhesion, growth and proliferation, osteoconduction, and even osteoinduction, which commonly results in de novo osteogenesis. The present work aimed to study the bone-repairing ability of hybrid matrixe...

We have observed an appearance of clear morphological structure in composites containing In2O3 nanocrystals (NCs) incorporated into polymethyl methacrylite (PMMA) matrices under optical treatment by a polarized femtosecond laser. The initial photoinduced treatment was carried out using a Ti:sapphire femtosecond laser emitting 140 fs p-polarized light at a maximum spectral wavelength 775 nm with...

Lipids are a major component of cells and play a variety of roles in organisms. In general, they play a key role in the structural composition of membranes. Some lipids, such as sphingoglycolipids, however, are also mediators of different biological processes, including protein transport, regulation of cell growth, cellular morphogenesis, neuronal plasticity, and regulation of the immune respon...

The traditional approach to building Bayesian networks is to build the graphical structure using a graphical editor and then add probabilities using a separate spreadsheet for each node. This can make it difficult for a design team to get an impression of the total evidence provided by an assessment, especially if the Bayesian network is split into many fragments to make it more manageable. Usi...

Insulator fault may lead to the accident of power network, thus the on-line monitoring of insulator is very significant. Low rates wireless network is used for data transmission of leakage current. Determination of the measurement matrix is the significant step for realizing the compressed sensing theory. This article comes up with new sparse matrices which can be used as compressed sensing mat...

Correct interactions between transcription factors (TFs) and their binding sites (TFBSs) are of central importance to gene regulation. Recently developed chromatin-immunoprecipitation DNA chip (ChIP-chip) techniques and the phylogenetic footprinting method provide ways to identify TFBSs with high precision. In this study, we constructed a user-friendly interactive platform for dynamic binding s...

A principally new approach to the classifications of nucleotide sequences based on the “natural” classification concept is proposed. As a result of “natural” classification of the nucleotide sequences, we obtain regularity matrices, where nucleotides are interconnected by regularities. Method, algorithm and software system DNANatClass for performing the “natural” classification have been develo...

β-galactosidase simply known as lactase is a significant enzyme in food industry mainly used to hydrolyse lactose in milk. In addition to provide lactose free milk for lactose intolerant people, hydrolysis of lactose avoids textural problems in frozen milk products. β-galactaosidase from different sources has been immobilized on many various type of matrixes including chitosan, alginate, sepabe...

To improve the machining precision and reduce the geometric errors for 5-axis machinetool, error model and calibration are presented in this paper. Error model is realized by the theory of multi-body system and characteristic matrixes, which can establish the relationship between the cutting tool and the workpiece in theory. The accuracy calibration was difficult to achieve, but by a laser appr...
