We assessed the roles of ${it Arabidopsis thaliana}$ ${it POLH, PCNA1}$ and ${it PCNA2}$ in TLS mediated UV resistance. ${it Arabidopsis}$ ${it POLH}$ defective mutants sensitized growth of roots and whole plants to UV radiation indicating AtPol$$eta$$ contributes to UV resistance. ${it POLH}$ alone did not complement the UV sensitivity conferred by deletion of yeast ${it RAD30}$, although AtPol$$eta$$ exhibited cyclobutane dimer bypass activity and interacted with yeast PCNA in vitro. Co-expression of ${it POLH}$ and ${it PCNA2}$, but not ${it PCNA1}$, restored normal UV resistance and mutation kinetics in the ${it rad30}$ mutant. A single residue difference at site 201, which lies adjacent to the lysine ubiquitylated in PCNA, appeared responsible for the inability of PCNA1 to function with AtPol$$eta$$ in UV treated yeast. PCNA interacting protein boxes and an ubiquitin-binding motif in AtPol$$eta$$ were found to be required for restoration of UV resistance in the ${it rad30}$ mutant by ${it POLH}$ and ${it PCNA2}$. These observations indicate AtPol$$eta$$ can catalyse TLS past UV induced DNA damage, and link the biological activity of AtPol$$eta$$ in UV irradiated cells to PCNA2 and PCNA-and ubiquitin-binding motifs in AtPol$$eta$$.

We present transverse-field (TF) measurements of the in-plane magnetic-field penetration depth $$lambda (T)$$ in single-crystalline PuCoGa$$_5$$ for 0.06 T applied filed. We find that the temperature dependence of the superfluid density, and therefore $$Deltalambda (T)=lambda (T)-lambda (0)$$, is $$propto T$$ for $$T/T_c le 0.5$$. We estimate that the measured $$lambda (0)=241(3)$$ nm. Zero-field (ZF) measurements find no evidence for time-reversal symmetry violation. The ZF and TF measurements are consistent with an even-parity (pseudo-spin singlet), d-wave paring state.

Spin freezing and non-glassy dynamics in Ce$$_{0.2}$$La$$_{0.8}$$RhIn$$_5$$

Zero-field muon spin relaxation ($$mu$$SR) in non-Fermi liquid Ce$$_{0.2}$$La$$_{0.8}$$RhIn$$_5$$ reveals disordered spin freezing with a sharp transition at 0.16 K. The frozen moment at $$T=0$$ is estimated as $$sim$$0.13 $$mu_B$$/Ce, an order of magnitude smaller than found from thermodynamic data at higher fields and temperatures. Longitudinal-field $$mu$$SR exhibits no dynamic relaxation at any temperature, showing that the spin freezing is not accompanied by the slow spin fluctuations found in spin glasses above the glass temperature and in other disordered non-Fermi liquid systems.


Penetration depth study in the heavy-fermion superconductor PrOs$$_4$$Sb$$_{12}$$

The penetration depth $$lambda$$ in the filled-skutterudite heavy-fermion superconductor PrOs$$_4$$Sb$$_{12}$$ has been measured using transverse-field muon spin rotation (TF-$$mu$$SR). It is found to be temperature-independent at low temperatures, consistent with a nonzero gap for point nodes in the gap. A $$sim$$10$$%$$ discrepancy is found at low temperatures. This may be due to mechanisms that modify the vortex-state field distribution, or to the surface scattering which breaks pairs in an odd-parity superconductor. Alternatively, it may be a matter of field orientation of nodal gap structure in the $$mu$$SR measurements.

原研は、日米核融合研究協力協定Annex IV延長に基づき米国ロスアラモス国立研究所のTSTAにおいて非定常運転対応核融合炉燃料循環系実証試験及び増殖ブランケットトリチウム回収系模擬試験を行ってきた。本試験は、TSTA FCUの低温モレキュラーシーブ塔とJFCUのパラヂウム拡散器を組み合わせた世界初の増殖ブランケットトリチウム回収系に関するトリチウムを用いた、模擬実証試験であった。試験の結果、トリチウムを含む模擬ブランケットパージガス(流量12.6l/min)を低温吸着方式で3時間以上にわたって精製回収し、回収されたトリチウムガスを3時間以内にパラヂウム拡散器で純化する運転が可能であることが実証された。本報告は、この試験結果について詳細に解析、検討したものである。
