A quasifree ($$p$$,$$pn$$) experiment was performed to study the structure of the Borromean nucleus $$^{17}$$B, which had long been considered to have a neutron halo. By analyzing the momentum distributions and exclusive cross sections, we obtained the spectroscopic factors for $$1s_{1/2}$$ and $$0d_{5/2}$$ orbitals, and a surprisingly small percentage of 9(2)% was determined for $$1s_{1/2}$$. Our finding of such a small $$1s_{1/2}$$ component and the halo features reported in prior experiments can be explained by the deformed relativistic Hartree-Bogoliubov theory in continuum, revealing a definite but not dominant neutron halo in $$^{17}$$B. The present work gives the smallest $$s$$- or $$p$$-orbital component among known nuclei exhibiting halo features and implies that the dominant occupation of $$s$$ or $$p$$ orbitals is not a prerequisite for the occurrence of a neutron halo.

We developed a six-axis multi-anvil press, ATSUHIME, for high-pressure and high-temperature in situ time-of-flight neutron powder diffraction experiments. The press has six orthogonally oriented hydraulic rams that operate individually to compress a cubic sample assembly. Experiments indicate that the press can generate pressures up to 9.3 GPa and temperatures up to 2000 K using a 6-6-type cell assembly, with available sample volume of about 50 mm $$^{3}$$. Using a 6-8-type cell assembly, the available conditions expand to 16 GPa and 1273 K. Combination of the six-axis press and the collimation devices realized high-quality diffraction pattern with no contamination from the heater or the sample container surrounding the sample. This press constitutes a new tool for using neutron diffraction to study the structures of crystals and liquids under high pressures and temperatures.

Legume plants tightly control the development and number of symbiotic root nodules. In ${it Lotus japonicus}$, this regulation required ${it HAR1}$ in the shoots, suggesting that a long-distance communication between the shoots and the roots may exist. To better understand its molecular basis, we isolated and characterized a novel hypernodulating mutant of ${it L. japonicus}$ named ${it too much love}$ (${it tml}$). Reciprocal grafting with wild type showed that ${it tml}$ hypernodulation is determined by the root genotype. Moreover, grafting a ${it har1}$ shoot onto a ${it tml}$ rootstock did not exhibit any obvious additive effects on the nodule number. These observations indicate that a shoot factor ${it HAR1}$ and a root factor ${it TML}$ participate in the same genetic pathway which governs the long-distance signaling of nodule number control. ${it TML}$ may function downstream of ${it HAR1}$ and the gene product ${it TML}$ might serve as a receptor or mediator of unknown mobile signal molecules that are transported from the shoots to the roots.

Roles of arabidopsis ${it AtREV1}$ and ${it AtREV7}$ in translation synthesis

The error-prone DNA translation synthesis (error-prone TLS) has been well characterized in yeast and mammalians, but not in higher plants. Recent finding of an ${it AtREV3}$-disrupted mutant (${it rev3}$) in Arabidopsis suggested that the error-prone TLS is significant for tolerance to DNA damages in higher plant. To clarify the details of the error-prone TLS in higher plants, we analyzed the T-DNA inserted Arabidopsis mutants defective in ${it AtREV1}$ or ${it AtREV7}$ genes, which are thought to be involved in the error-prone TLS system. The ${it AtREV1}$ mutant (${it rev1}$) was sensitive to UV-B and cisplatin. The ${it AtREV7}$ mutant (${it rev7}$) was sensitive to long-term UV-B and cisplatin. These results suggest TLS mechanism exists in a higher plant and show that ${it AtREV1}$ and ${it AtREV7}$ have important roles in tolerating exposure to DNA-damaging agents, but their function might be redundant.

no journal, , 

Neutron diffraction is a powerful tool to investigate hydrogen in minerals and rocks. New neutron diffraction beamline "PLANET" is currently under construction at BL11 of Materials and Life Science Experimental Facility (MLF) at J-Parka Tokai, Ibaraki. One of the unique features of this beamline is that 6-rams multi-anvil high-pressure apparatus (ATSUHIME) is installed, to generate high pressure and high temperature conditions of earth's mantle. Maximum load of each hydraulic ram is 500-ton. Each rams are controlled independently by six plunger pumps. The press will be installed at experimental hutch at Feb. 2012. I will present the current status of the 6-rams multi-anvil apparatus.
