Authors: Huang Wen Lin , Liaw Chyn , Tsai Chia Ta , Ho Shinn Ying
Published: September 2013

Many mitotic proteins are assembled into protein super complexes in three regions - midbody, centrosome and kinetochore (MCK) - with distinctive roles in modulating the mitosis process. However, more than 16% of the mitotic proteins are in multiple regions. Advance identification of mitotic proteins will be helpful to realize the molecular regulatory mechanisms of this organelle. Few ensemble-classifier methods can solve this problem but these methods often fuse various complementary features. In which, Gene ontology (GO) terms play an important role but the GO-term search space is massive and sparse. This motives this work to present an easily implemented method, namely mMck-GO, by identifying a small number of GO terms with support vector machine (SVM) andk-nearest neighbor (KNN) in predicting single-and multiple-region MCK proteins. The mMck-GO method using a simple grouping scheme based on a SVM classifier assembles the GO terms into several groups according to their numbers of annotated proteins in the training dataset, and then measures which top-grouped GO terms performs the best. A new MCK protein dataset containing 701 (611 single-and 90 multiple-region) is established in this work. None of the MCK proteins has a 25% pair-wise sequence identity with any other proteins in the same region. When performing on this dataset, we find that the GO term with the maximum annotation number annotates 49.2% of the training protein sequences; contrarily, 56.5% of the GO terms annotate single one protein sequence. This shows the sparse character of GO terms and the effectiveness of top-grouped GO terms in distinguishing MCK proteins. Accordingly, a small group of top 134 GO terms is identified and mMck-GO fuses the GO terms with amino acid composition (AAC) as input features to yield and independent-testing accuracies of 71.66% and 69.18%, respectively. Top 30 GO terms contain eight, eight, and 14 GO terms belonging to molecular function, biological process and cellular component branches, respectively. The 14 GO terms in cellular-component ontology in addition to centrosome and kinetochore are reverent to subcellular compartments, microtubule, membrane, and spindle, where GO:0005737 (cytoplasm) is ranked first. The eight GO terms enabling molecular functions comprise GO:0005515 (protein binding), GO:0000166 (nucleotide binding), and GO:0005524 (ATP binding). Most of the eight GO terms in biological-process ontology are reverent to cell cycle, cell division and mitosis but two GO terms, GO:0045449 and GO:0045449, are reverent to regulation of transcription and transport processes, which helps us to clarify the molecular regulatory mechanisms of this organelle. The top-grouped GO terms can be as an indispensable feature set when concerning other feature types to solve multiple-class problems in the investigation of biological functions.

Published: September 2013

At present, the world is facing energy shortage, while the CO2 emitted from the combustion of traditional energy causes greenhouse effect. As a result, the green concept of energy saving has emerged. Among the current green energies, solar power is not cost effective, and wind energy has great potential in terms of cost and efficiency. Most of wind energy is used for wind power generation, however, the wind energy is also applicable to heating, and the generated heat energy can be used for hot water supply and temperature regulation. The wind heating modes include fluid mixing and solid friction modes. This study used natural wind to design a machine producing heat energy by solid friction. The energy transfer mode of the wind heating system was to convert the blade extracted wind energy into mechanical energy, and use friction to generate mechanical energy generates. The heat energy was transferred to the water through heat exchange to increase the water temperature. The friction mode was to rub the brake pad against the disc to produce heat, and using the compression spring to adjust the magnitude of the friction. The pump circulated water to implement forced convection, and the heat exchange was designed as flowing water channel increasing the heat transfer time. The experimental results showed that the water storage temperature can be increased.

Published: September 2013

The requirement of the accuracy of microscopic measurements becomes more and more high, and traditional methods have been unable to meet the demands. Digital image deconvolution techniques are applied in microscopic measurement. By fabricating a pointolite, the point spread function of the optical system is measured, and then the geometric blurring in traditional microscopy is removed by using the maximum likelihood estimation algorithms and iteration threshold segmentation algorithms. The technique is applied to measure the total content of perlite and spheroidal graphite in spheroidal graphite iron accurately and easily, and then to measure the area of a scratch scaled in 10 microns on a medical department of orthopedics plates. The technique makes great sense in the development of corresponding measurement.

Authors: Wang Ying Hui , Wu Wei Yong
Published: September 2013

Isometric transformation with geodesic distance is widely used in similarity analysis or 3D retrieval of non-rigid objects. However, geodesic distance is sensitive to topology noise and can be problematic in cases where objects topology is changed locally. In order to solve the problem, a new method based on diffusion map was proposed. We used diffusion map to compute embedded models and utilized thin-plate spline (TPS) to match the embedded models to obtain the similarity error of original objects. The method was tested on some examples, the results show that the new method is suitable to similarity analysis or 3D retrieval of non-rigid objects, moreover, our method is robust to the deformed objects with topology noise.

Published: September 2013

Heat equation is considered as the most typical one of parabolic equation, which describes many physical phenomena, such as heat conduction, molecule diffusion, etc. In this paper, we investigate the definite solution problem for a diffusion equation. We obtain that if the solution of the diffusion equation is a function of a combination of variables, the solution must satisfies an ordinary differential equation. Then we apply this method to a magma heat conduction model, which shows our research method is feasible and effective.

Most of photocatalytic reaction taken place in a slurry type reactor, which is of poor light utilization and difficulty to recycling of photocatalyst. To overcome these drawbacks, a floating photocatalyst (TiO2/EP) was prepred by hrothermal method, in which EP(Expanded Perlite) was used as an substrate. Photocatalysts activity was evaluated under UV light using Rhodamine B as the pollutant model. The effect of heating temperature, heating time and dosage of EP on activity of TiO2/EP were Discussed. The results showed 2h and 200°C were the optimal conditions and the dosage of EP has no significant effect on activity of TiO2/EP. The results of XRD and SEM showed TiO2 is anatase form, well crystallized and dispersed; its particle size is about 100~150nm. This floating photocatalyst can remove about 97.4% rhodamine B(10mg/L) during 90min under UV light. It has broad prospects for engineering applications.

Authors: Fu Ai Hong , Li Wei Hong , Chen Ya Ning
Published: September 2013

Using Tamarix ramosissima Lbd. growing in the extremely arid regions along the lower reaches of Tarim River, Xinjiang, we preformed a series of investigations on the effects of weather, soil moisture and salt on the stem water potential (ψs) of T. ramosissima. We identified the leading environmental factors affecting ψs of T. ramosissima and detected the thresholds of the environmental factors. First, the soil moisture was the most important factor affecting ψs of T. ramosissima among all the environmental factors. While there was no minimum threshold of the soil moisture for T. ramosissima to absorb moisture from soil, the highest threshold of the soil moisture was 36%. When the soil moisture was higher than 36%, there was a significant change on ψs of T. ramosissima. Our study provides crucial empirical data for keeping the normal growth of T. ramosissima.
