Yb 3+ complexes with two nitrilotriacetic acid molecules were prepared and their compositions were determined as K 3[Yb(nta) 2(H 2O)]·5H 2O and Na 3[Yb(nta) 2]·6H 2O by elemental analyses. Their structures were characterized by single crystal X ray diffraction analyses. In complex K 3[Yb(nta) 2(H 2O)]·5H 2O, the YbN 2O 7 part forms a nine coordinate monocapped square antiprismatic structure. In complex Na 3[Yb(nta) 2]·6H 2O, the YbN 2O 6 part forms an eight coordinate square antiprismatic structure. It can be seen that the outer cations (K + and Na +) greatly affect the coordination number and coordinate structure from these results.

We report on the calculations of transition wavelengths and weighted oscillator strengths for 2s22p^6 2s2p^6np （4 〈 n 〈 20） electric dipole （El） transitions of Cu^19＋ ion. The flexible atomic code （FAC） has been adopted for the calculations. Comparisons are made with the experimental data available, showing that the present results for 4 〈 n 〈 6 are more accurate than the previous calculated values. Furthermore, combining the quantum defect theory （QDT） with the transition energies of 2s^22p^62s2p^6np, the quantum defects for 2s2p^6np Rydberg series of Cu^19＋ ion are determined. In addition, the energies of any highly excited states （n 〉 20） for this series can be reliably predicted using the QDT and the given quantum defects. The ionization energies for Cu^19＋ and Cu^20＋ ions are also calculated and they excellently accord with previous experimental and calculated values.

Let H be a Hopf π-coalgebra over a commutative ring k with bijective antipode S, and A and B right π-H-comodulelike algebras. We show that the pair of adjoint functors （F3 = A  Bop A□ HBop -,G3 = （-）coH） between the categories A□HBopM and AMπB-H is a pair of inverse equivalences, when A is a faithfully flat π-H-Galois extension. Furthermore, the categories Moritaπ-H（A,B） and Morita □π-H（AcoH,BcoH） are equivalent, if A and B are faithfully flat π-H-Galois extensions.

Calcineurin（Cn or CaN） is implicated in the control of skeletal muscle fiber phenotype and hypertrophy. However, little information is available concerning the expression of Cn in chickens. In the present study, the expression of two Cn subunit genes（Cn Aα and Cn B1） was quantified by q PCR in the lateral gastrocnemius（LG, mainly composing of red fast-twitch myofibers）, the soleus（mainly composing of red slow-twitch myofibers） and the extensor digitorum longus（EDL, mainly composing of white fast-twitch myofibers） from Qingyuan partridge chickens（QY, slow-growing chicken breed） and Recessive White chickens（RW, fast-growing chicken breed） on different days（1, 8, 22, 36, 50 and 64 days post-hatching）. Although Cn Aα and Cn B1 gene expressions were variable with different trends in different skeletal muscles in the two chicken breeds during postnatal growth, it is highly muscle phenotype and breed specific. In general, the levels of Cn Aα and Cn B1 gene expressions of the soleus were lower than those of EDL and LG in both chicken breeds at the same stages. Compared between the two chicken breeds, the levels of Cn Aα gene expression of the three skeletal muscles in QY chickens were higher than those in RW chickens on days 1 and 22. However, on day 64, the levels of both Cn Aα and Cn B1 gene expressions of the three skeletal muscles were lower in QY chickens than those in RW chickens. Correlation analysis of the levels of Cn Aα and Cn B1 gene expressions of the same skeletal muscle showed that there were positive correlations for all three skeletal muscle tissues in two chicken breeds. These results provide some valuable clues to understand the role of Cn in the development of chicken skeletal muscles, with a function that may be related to meat quality.

为了实现含竖向成层介质以及表面不规则地形场地中标量波传播问题的高效且高精度求解，该文基于连分式展开和扩展的一致边界，建立了一种频域下折线形高精度人工边界条件。通过在每个竖向地层内引入独立的斜角坐标变换，新的人工边界条件可以用于多起伏地表地形条件。新的折线形人工边界在频域下推导，仅含有连分式阶数一个待定实参数，用于调整计算精度，该参数不随外行波的频率和传播角度改变。人工边界条件可以与内域有限元方程无缝耦合，应用简单方便。由于新边界条件的高精度，内域尺寸可以取较小甚至可以直接将人工边界加在结构周围或者地表，从而极大提高计算效率。通过典型数值算例，将人工边界计算模型与有限元大模型的解进行了对比分析，验证了该文提出的折线形人工边界条件的有效性和高精度。
