Genes for V-H(+)-ATPase subunits were identified and cloned from the salt-tolerant wheat mutant RH8706-49. Sequences of these genes are highly conserved in plants. Overexpression of these genes in Arabidopsis thaliana improved its salt tolerance, and increased the activities of V-H(+)-ATPase and Na(+)/H(+) exchange, with the largest increase in plants carrying the c subunit of V-H(+)-ATPase. Re...

We studied proton beam production from a laser ion source using hydrogen rich target materials. In general, gas based species are not suitable for laser ion sources since formation of a dense laser target is difficult. In order to achieve reliable operation, we tested hydride targets using a sub nanosecond Q-switched Nd-YAG laser, which may help suppress target material consumption. We detected...

The MCM (minichromosome maintenance) proteins of archaea are widely believed to be the replicative DNA helicase of these organisms. Most archaea possess a single MCM orthologue that forms homo-multimeric assemblies with a single hexamer believed to be the active form. In the present study we characterize the roles of highly conserved residues in the ATPase domain of the MCM of the hyperthermoph...

The measurements of the longitudinal proton structure function F L in deep inelastic positron-proton scattering at low Bjorken x are presented. The data were taken by the HERA experiments H1 and ZEUS in a series of runs with different proton beam energies. The measured longitudinal structure function is compared to theoretical predictions in higher order QCD and using dipole model calculations....

In order to establish a self-sufficient supply of (99m)Tc, we studied feasibilities to produce its parent nucleus, (99)Mo, using Japanese accelerators. The daughter nucleus, (99m)Tc, is indispensable for medical diagnosis. (99)Mo has so far been imported from abroad, which is separated from fission products generated in nuclear reactors using enriched (235)U fuel. We investigated (99m)Tc produc...

HERA-B is a hadroproduction experiment located at DESY in Hamburg, Germany. The experiment produces B mesons and baryons by inserting thin wire targets into the halo of the proton beam circulating in the HERA storage ring. The B decays are studied to search for evidence of CP violation and constrain the angle β and possibly γ and α of the CKM unitarity triangle. The experiment also produces B s...

In recent years, structural information on the F(1) sector of the ATP synthase has provided an insight into the molecular mechanism of ATP catalysis. The structure strongly supports the proposal that the ATP synthase works as a rotary molecular motor. Insights into the membrane domain have just started to emerge but more detailed structural information is needed if the molecular mechanism of pr...

Parton luminosities are convenient for estimating how the physics potential of Large Hadron Collider experiments depends on the energy of the proton beams. I present parton luminosities, ratios of parton luminosities, and contours of fixed parton luminosity for gg, ud̄, and qq interactions over the energy range relevant to the Large Hadron Collider, along with example analyses for specific proce...
