In endoreduplicating cells, two thirds of the chromatid exchanges observed after BrdU treatment are symetrical, like on the two elements of the diplochromosome. The other third seems to occur at random on one or the other element. Each double symetrical exchange would result from a single event occurring at the next to last cell cycle before the mitosis observed. The other exchanges would result from last events of the cycle. Thus the frequency of events would be the same at each cell generation. A theoretical model is proposed which explains t...

The stability and structures of titanium-doped gold clusters Au(n)Ti (n=2-16) are studied by the relativistic all-electron density-functional calculations. The most stable structures for Au(n)Ti clusters with n=2-7 are found to be planar. A structural transition of Au(n)Ti clusters from two-dimensional to three-dimensional geometry occurs at n=8, while the Au(n)Ti (n=12-16) prefer a gold cage structure with Ti atom locating at the center. Binding energy and second-order energy differences indicate that the Au(14)Ti has a significantly higher st...

A seven-electron cluster [Mo3(mu3-S){mu3-SC(CO(2)CH(3))=C(CO(2)CH(3))S}{mu-SC(CO(2)CH(3))=CH(CO(2)CH(3))}(dtp)3(mu-OAc)] [2, S2P(OC(2)H(5))2-; dtp = diethyldithiophosphate] and an organometallic cluster [Mo3(mu3-S){mu3-SC(CO(2)CH(3))=C(CO(2)CH(3))S}{mu-SC(CO(2)CH(3))CH(OCH(3))(CO2)}(dtp)2(CH(3)OH)(mu-OAc)](Mo-C) (3) were obtained by reaction in methanol of the sulfur-bridged trinuclear complex [Mo3(mu3-S)(mu-S)3(dtp)3(CH(3)CN)(mu-OAc)] (1) with dimethylacetylenedicarboxylate (DMAD). The X-ray structures of 2 and 3 revealed the adduct formation ...

The persistence probability, P(C)(t), of a cluster to remain unaggregated is studied in cluster-cluster aggregation, when the diffusion coefficient of a cluster depends on its size s as D(s) approximately s(gamma). In the mean field the problem maps to the survival of three annihilating random walkers with time-dependent noise correlations. For gamma> or =0 the motion of persistent clusters becomes asymptotically irrelevant and the mean-field theory provides a correct description. For gamma

IscU functions as a scaffold for Fe-S cluster assembly and transfer, and is known to be a substrate protein for molecular chaperones. Kinetic studies of Fe-S cluster transfer from holo IscU to apo Fd in the presence of chaperone DnaK demonstrate an inhibitory effect on the rate of Fe-S cluster transfer from IscU. Binding of DnaK reduces the rate of formation of the IscU-Fd complex (greater than 8-fold), but has little influence on the intrinsic rate of iron-sulfur cluster transfer to apo Fd. Apparently the molecular chaperone DnaK does not faci...

Abstract This research purpose was to explore industry cluster alternative factors, cluster formatting factors, cluster effect factors, and correlation of cluster alternative dimensions with cluster formation dimensions, and correlation of industry cluster formatting dimensions and industry cluster effect dimensions. This research utilizes Taiwan precision machinery industry for a case study. The methodology is through experts method, factor examination, to explore the industry cluster alternative factors, cluster formation factors, and cluste...

Abstract The MAC based on competition doesn't do any contribution in the energy savings, because it will lead to conflict, crosstalk, idle intercept and control expenses in communication. TDMA scheduling system based on the structure of cluster can effectively improve the scalability, save energy and does not increase node costs, but it also brought transmission interference between clusters. We proposed an Inter -cluster and Intra-cluster TDMA scheduling algorithm cluster-based (USA), each round of data collection time is divided by layers al...
