Generation of multi-photon Fock states at telecommunication wavelength using picosecond pulsed light.

Multi-photon Fock states have diverse applications such as optical quantum information processing. For the implementation of quantum information processing, Fock states should be generated within the telecommunication wavelength band, particularly in the C-band (1530-1565 nm). This is because mature optical communication technologies can be leveraged for transmission, manipulation, and detection.

Centromere/kinetochore is assembled through CENP-C oligomerization.

Kinetochore is an essential protein complex required for accurate chromosome segregation. The constitutive centromere-associated network (CCAN), a subcomplex of the kinetochore, associates with centromeric chromatin and provides a platform for the kinetochore assembly. The CCAN protein CENP-C is thought to be a central hub for the centromere/kinetochore organization.

Structural Analysis of Hen Egg Lysozyme Refolded after Denaturation at Acidic pH.

Protein structures fluctuate in solution; therefore, proteins have multiple stable structures that are slightly different from each other. In this study, we determined the crystal structure of hen egg lysozyme refolded after denaturation at acidic pH (rHEL) and found a structure different from native HEL (nHEL). The different local conformations of the peptide bond between Asp101 and Gly102 found in the crystal structure was supported by the NMR results for nHEL and rHEL.

2,4-Dichlorophenoxyacetic acid (2,4-D)- and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T)-degrading gene cluster in the soybean root-nodulating bacterium Bradyrhizobium elkanii USDA94.

Herbicides 2,4-dichlorophenoxyacetic acid (2,4-D)- and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T)-degrading Bradyrhizobium strains possess tfdAα and/or cadABC as degrading genes. It has been reported that root-nodulating bacteria belonging to Bradyrhizobium elkanii also have tfdAα and cadA like genes but lack the ability to degrade these herbicides and that the cadA genes in 2,4-D-degrading and non-degrading Bradyrhizobium are phylogenetically different. In this study, we identified cadRABCK in the genome of a type strain of soybean root-nodulating B.
