Glacial HisTories From The East Antarctic Ice Sheet (Eais) Provide Keys To UnderstAndIng Correlations Between The Eats And Global Climate. They Are Especially Helpful In The Assessment Of Global Sea Level Change  And As a Means Of Quantifying The Magnitude Of pAst Glacial Activity And The RAte At Which Ice Responded To climAte Change. Given The Significance Of Eais Glacial hisTories  It Is Imperative That More Glacial Chronologic Data For thIs Region Be Obtained  Especially For The Mid-to-lAte Pleistocene. We Report Cosmogenic Be-10 Surface Exposure DAtIng Results From Glacially Transported Cobbles Embedded In Blue-ice moraIne MAterial At Mount hardIng  The Grove Mountains  Eais. Forty Exotic Cobbles Sampled AlOng Two PrOfiles (a And b) On This Blue-ice MoraIne Present Apparent Exposure-ages RangIng From 7.2 To 542.2 Ka. We Explore This Scattered Dataset By UsIng PrIncipal compOnent Analysis (Pca) To Identify Statistically Significant Trends In The Data. We Identify a correlatiOn betWeen Exposure-age And Distance Of The Cobbles From Mount hardIng. In prOfile a  Cobbles Further From Mount HardIng Yield Older Exposure-ages Than Those That Are Relatively Close. In Profile b  Cobbles Closer To Mount HardIng Are Found To Have Relatively Older Exposure-ages. In Term Of Glacial hisTory We Suggest That The Direction Of Ice Flow Changed durIng The Period From Similar To 60 To 200 Ka  And That Multiple Glacial Fluctuations Occurred In The Mid-late Pleistocene.

2-Methyl-1,3,6-trihydroxy-9,10-anthraquinone (MTA)  one of the major components isolated from the traditional  Chinese medicine Rubia yunnanensis  exhibited inhibitory activity on the proliferation of several  human cancer cell lines. The results from an annexin V-FITC (fluoresein-5-isothiocyanate) apoptosis assay  and DNA content analysis showed that MTA exerted cytotoxicity via apoptosis induction and G2/M cell cycle  arrest in human cervical carcinoma HeLa cells. Further  MTA was found to induce apoptosis of HeLa cells  through the mitochondria-mediated pathway. It caused the translocation of Bax to the mitochondria and  release of cytochrome c into the cytosol  which caused the cleavage of caspase and poly(ADP-ribose)  polymerase and finally triggered the apoptosis. Furthermore  the p53/p21/Cdc2-cyclin B1 signaling was  found related to the G2/M arrest caused by MTA. The over-expression of p21 and down-expression of  cyclin B1 caused by MTA inactivated the Cdc2-cyclin B1 complex of G2/M checkpoint and finally caused  the G2/M arrest in HeLa cells. This study demonstrated that MTA is a potential anti-cancer component of  R. yunnanensis  a folk anti-cancer herb used in Yunnan  China.

Structural design of large aperture mirror is one of the key technologies for space telescope development. To meet the requirements of high stiffness  strength and thermal dimensional stability  some factors such as support scheme  materials selection  lightweight design and flexible support design were taken into account. The three supports location of the mirror was determined according to the modal analytical solution. By adjusting the parameters of flexure hinge  influences of gravity  assembly stress and thermal stress on the mirror were reduced obviously. Finite element analysis (FEA) results indicate that the surface accuracy reach to rms10.2nm and 10.8nm under the gravity along optical axis direction and 5C uniform temperature rise respectively  the fundamental frequency of the mirror component is 268Hz. Dynamics test shows that the first order natural frequency is 256Hz  which shows an error less than 5% compared to FEA results. (2013) Trans Tech Publications  Switzerland.
