Parallel Functional Programming on Recursively Defined Data via Data-Parallel Recursion (2001)

Susumu Nishimura, Atsushi Ohori

This article proposes a new language mechanism for data-parallel processing of dynamically allocated recursively de ned data. Different from the conventional array-based dataparallelism, it allows...

A Calculus for Exploiting Data Parallelism on Recursively Defined Data (1999)

Mmh/Ogg1 gene inactivation results in accumulation of 8-hydroxyguanine in mice

Minowa, Osamu, Arai, Tsuyoshi, Hirano, Masanori, Monden, Yoshiaki, Nakai, Shigeyasu, Fukuda, Mayuko, ...

The major mutagenic base lesion in DNA caused by exposure to reactive oxygen species is 8-hydroxyguanine or 7,8-dihydro-8-oxoguanine (8-OH-G). Products of the human MMH/OGG1 gene are known to...

Early embryonic lethality caused by targeted disruption of the mouse selenocysteine tRNA gene (Trsp)

Bösl, Michael R., Takaku, Kazuaki, Oshima, Masanobu, Nishimura, Susumu, Taketo, Makoto M.

Selenoprotein biosynthesis is mediated by tRNASec, which inserts selenocysteine at UGA codons in a complex, context-specific manner. This opal suppressor serves in the conversion of serine to...

Homologous Terminal Sequences in the Double-Stranded RNA Genome Segments of Cytoplasmic Polyhedrosis Virus of the Silkworm Bombyx mori

Kuchino, Yoshiyuki, Nishimura, Susumu, Smith, Robert E., Furuichi, Yasuhiro

The 3′-terminal regions (20 to 32 residues) of the genome double-stranded RNA (dsRNA) segments of cytoplasmic polyhedrosis virus were sequenced. The dsRNAs, which were labeled at their 3′ termini...

8-Hydroxyguanine in a mutational hotspot of the c-Ha-ras gene causes misreplication, ‘action-at-a-distance’ mutagenesis and inhibition of replication

Jałoszyński, Paweł, Masutani, Chikahide, Hanaoka, Fumio, Perez, Ana Blanco, Nishimura, Susumu

Mutations in particular codons of c-Ha-ras have a strong activating potential, and an activated ras oncogene has been found in a number of human cancers. Using fragments of the human c-Ha-ras gene...
