We compute the Fadell-Husseini index of the dihedral group D8 = (Z2)2 ⋊ Z2 on S × S, that is, the kernel of the map in equivariant cohomology H ∗ D8 (pt,F2) −→ H ∗ D8 (Sd × Sd,F2). This establishes the complete cohomological lower bound for the two hyperplane case of Grünbaum’s 1960 mass partition problem: For which d and j can two hyperplanes be found that cut j arbitrary measures on R into fo...

We address a few subtle issues regarding the interacting D0-D8 system. There are two existing interpretations for the counter-intuitive non-vanishing attractive cylinder-diagram R-R potential. We improve them each by properly dealing with the divergence of potential in the R-R as well as the NS-NS sector, which has been ignored so far. We further test them by considering the D8 to carry a flux,...

This study was to explore the mechanism of acupuncture on regulating the endometrial angiogenesis and uterus dendritic cells (uDCs) during the peri-implantation period. Rats, in early pregnancy, were randomized into five groups: normal (N), model (M), acupuncture (A), progesterone (P), and A + P groups. The COH model was established using pregnant mare serum, combined with human chorionic gonad...

We construct unstable system D8 + D8 as a kink solution on world-volume of non-BPS D9-brane in IIA theory. Further we will make other checks confirming validity of our approach.

The microbial community in the human colon contains bacteria that reduce cholesterol to coprostanol, but the species responsible for this conversion are still unknown. We describe here the first isolation and characterization of a cholesterol-reducing bacterium of human intestinal origin. Strain D8 was isolated from a 10(-8) dilution of a fresh stool sample provided by a senior male volunteer w...

D8 and Mpl1 are two dominant dwarfing mutations of maize. Although they differ in severity of dwarfism, both D8 and Mpl1 mutants are unresponsive to gibberellin (GA). Because of their close phenotypic resemblance to the recessive GA-sensitive dwarf mutants these dominant mutations may identify a gene whose product is involved in the reception of GA. With this possibility in mind we have studied...
