An incomplete specimen of Sinosauropteryx prima collected from the Early Cretaceous Yixian Formation of the Dawangzhangzi area in Lingyuan, western Liaoning is depicted. It represents the first systematically described material of this feathered compsognathid outside the Sihetun area in Beipiao. This specimen shows some diagnostic features of Sinosauropteryx prima, such as the very short forelimb in relation to hindlimb with the length ratio of humerus plus radius to femur plus tibia just around 30%, and the long and massive first manual ungual subequal in length to radius. The presence of Sinosauropteryx prima only at Sihetun and Dawangzhangzi supports the suggestion that the fossil-bearing beds in the Sihetun and Dawangzhangzi areas are equivalent to each other within the Yixian Formation.

Metallothioneins (MTs) are a group of low molecular mass and cysteine-rich proteins that can chelate heavy-metal ions. In this paper,Northern blot analysis was used to investigate the influence of lead stress on the expression patterns of 10 rice class I MT genes (OsMT-Is) in rice seedlings. With the ex-ception of OsMT-I-3b,the data demonstrate dynamic changes of 9 OsMT-I transcripts in response to Pb2+ treatment in rice seedling roots. Of these genes,transcription of OsMT-I-1a,OsMT-I-1b,OsMT-I-2c,OsMT-I-4a,OsMT-I-4b and OsMT-I-4c increased significantly,while transcription of OsMT-I-2a and OsMT-I-3a increased marginally. In contrast,the expression of OsMT-I-2b was inhibited. Pb2+ induced the expression of 6 OsMT-I genes in seedling shoots,but had no obvious effects on the expression of OsMT-I-1a,OsMT-I-1b,OsMT-I-4a and OsMT-I-4b. All the 10 OsMT-Is had enhanced lead tolerance when heterologously expressed in lead-sensitive yeast mutant cells. These results provide an expression profile of the rice MT gene family in response to Pb2+ stress in rice seedlings and demonstrate in-creased lead tolerance in sensitive yeast mutant cells expressing OsMT-Is. This study lays a foundation for further analysis of the role of the rice MT gene family in respond to Pb2+ stress.

By integrating the cooperative approach with the fast annealing coevolutionary algorithm (FAEA), a so-called cooperative fast annealing coevolutionary algorithm (CFACA) is presented in this paper for the purpose of solving high-dimensional problems. After the partition of the search space in CFACA, each smaller one is then searched by a separate FAEA. The fitness function is evaluated by combining sub-solutions found by each of the FAEAs. It demonstrates that the CFACA outperforms the FAEA in the domain of function optimization, especially in terms of convergence rate. The current algorithm is also applied to a real optimization problem of protein motif extraction. And a satisfactory result has been obtained with the accuracy of prediction achieving 67.0%, which is in agreement with the result in the PROSITE database.

Spider dragline silk, which is produced in spider major ampullate gland, is a composite proteinacious fiber with highly repetitive Ala-Gly-rich domain. The unique combination of both high tensile strength and high elasticity makes spider dragline silk superior to almost any other natural or synthetic fibers. Cloning of the genes reveals that the silk is composed of at least two major proteins. Each protein component contains multiple repeats of modular structures that alternate between Ala-rich domains and Gly-rich domains. Molecular engineering not only opens a door to the production of spidroins but also provides a valuable experimental system to test and further establish the relationship between modular structures and mechanical properties. Here, based on our own studies, we review the latest progress of the modular structure and genetic engineering and outline the future prospects.

In this work, physical models of neoclassical tearing modes （NTMs） including bootstrap current and multiple modulated electron cyclotron current drive model are applied. Based on the specific physical problems during the suppression of NTMs by driven current, this work compares the efficiency of continuous and modulated driven currents, and simulates the physical processes of multiple modulated driven currents on suppressing rotating magnetic island. It is found that when island rotates along the poloidal direction, the suppression ability of continuous driven current can be massively reduced due to current deposition outside the island separatrix and reverse deposition direction at the X point, which can be avoided by current drive modulation. Multiple current drive has a better suppressing effect than single current drive. This work gives realistic numerical simulations by optimizing the model and parameters based on the experiments, which could provide references for successful suppression of NTMs in future advanced tokamak such as international thermonuclear experimental reactor.

To promote the photocatalytic performance TiO2 and enlarge its application in visible region, carbon doped TiO2 (C/TiO2) composites were synthesized by wet impregnation method using sucrose as a precursor and used for phenol photocatalytic reaction. The synthesized products were characterized by Nitrogen adsorption-desorption isotherms (BET), X-ray diffraction (XRD), transmission electron microscopy (TEM) and UV-visible diffuse reflectance spectroscopy (UV-vis) techniques. The results showed that the obtained TiO2 was anatase phase in the C/TiO2 products, and its crystallite size was 11.7 nm, respectively. Carbon amount and calcined temperature of C/TiO2 can promote phenol removal. In this experiment, 5% carbon and 500 ℃ are the best choice for photocatalyst preparation. Under the UV light irradiation, 5%C/TiO2 (500 ℃, 2 h) exhibited the efficiency of 70.0% for phenol degradation within 150 min whereas TiO2 (500 ℃, 2 h) had 53.0% in the same duration of time. Also 5%C/TiO2 (500 ℃, 2 h) has higher photocatalytic performance under sunlight than pure TiO2. A combination of factors that include the smallest crystalline size, higher anatase percent, less band gap energy value and more oxygen vacant resulted in higher photocatalytic activities of 5%C/TiO2 (500 ℃, 2 h).
