  • Three new genera and species of siphonostomatoid copepods are described as associates of sponges from shallow water of Samar Island in the Philippines: Samarus filipes n. gen., n. sp., Paurocheres dentatus n. gen., n. sp., and Platymyzon umbonatum n. gen., n. sp. A new family Samarusidae is proposed to accommodate Samarus n. gen. which has rudimentary legs 1-5 represented only by filiform setae. Paurocheres n. gen. is characterized by 2-segmented endopod of leg 4 and reduced setation of legs, and Platymyzon n. gen. by missing of mandibular gnathobase.

  • Twelve species of cyclopoid copepods, including two new genera and ten new species, associated with polychaetes are described from Korea. The new taxa comprise Petalocopus planus n. gen. n. sp. in the Clausidiidae, Rhodinicola exilis n. sp. in the Clausiidae, Gastrodelphys vadicola n. sp. in the Gastrodelphyidae, Polyankylis estivalis n. sp. in the Polyankyliidae, Pentakela cylindrica n. gen. n. sp., Pseudanthessius oporinus n. sp. and P. petilus n. sp. in the Pseudanthessiidae, and Myxomolgus buanensis n. sp., M. dokdoicus n. sp. and Serpuliphilus antennatus n. sp. in the Sabelliphilidae. As characteristic features of the new genera, Petalocopus n. gen. has a pair of pedunculate suckers on the terminal segment of the antenna and an enlarged posterodistal seta on the second segment of antennule, and Pentakela n. gen. has five strong hooks on distal segments of antenna, three-segmented exopod and two-segmented endopod in legs 1 and 2, and one-segmented exopod and a lobate, rudimentary endopod in legs 3 and 4. The male of Maxilliclausia propria Kim, 2014 of the Clausiidae is recorded for the first time.

  • Six new species of copepods associated with polychaetes are described from Korea. Included are Indoclausia bipartita n. sp., Clausia parva n. sp., and Maxilliclausia propria n. gen. n. sp. in the Clausiidae; Pseudanthessius excertus n. sp. in the Pseudanthessiidae; and Polyankylis ovilaxa n. sp. and Sewelloya plana n. gen. n. sp. in the Polyankyliidae. The new genus Maxilliclausia has a peculiar maxilla in which the distal segment forms a sucking disk, a non-prehensile antenna, vestigial legs 3 and 5, and lacks a maxilliped and leg 4. The two new species of the Polyankyllidae are discovered as external associates of terebellid polychaetes. The new genus Sewelloya has a simple female maxilliped bearing only two small setae on its terminal segment, an uniramous leg 4 bearing 1-segmented exopod, and a reduced leg 5 represented by three setae. The genera Terebelliphilus Kim, 2001 which was originally placed in the Sabelliphilidae, and Octophiophora Stock, 1988 and Stockia Sebastian and Pillai, 1974, both of the latters with uncertain familial positions, are transferred to the Polyankyliidae. A key to five genera of the Polyankyliidae are provided.

  • Array redistribution is usually required to enhance algorithm performance in many parallel programs on distributed memory multicomputers. GEN_BLOCK redistribution, which is redistribution between different GEN_BLOCKs, is essential for load balancing. However, prior research on redistribution has been focused on regular redistribution, such as redistribution between different CYCLIC(N)s. GEN_BLOCK redistribution is very different from regular redistribution. Message passing in regular redistribution involves repetitions of basic message passing patterns, while message passing for GEN_BLOCK redistribution shows locality. This paper proves that two optimal condition, reducing the number of communication steps and minimizing redistribution size, are essential in GEN_BLOCK redistribution. Additionally, by adding a relocation phase to list scheduling, we make an optimal scheduling algorithm for GEN_BLOCK redistribution. To evaluate the performance of the algorithm, we have performed experiments on a CRAY T3E. According to the experiments, it was proven that the scheduling algorithm shows better performance and that the conditions are critical in enhancing the communication speed of GEN_BLOCK redistribution.

  • Terebelliphilus simplex n. gen., n. sp. and Myxomolgus invulgus n. sp. are described from the tubicolous polychaetes found in the intertidal shores in the Yellow Sea. The new genus Terebelliphilus belongs to the family Sabelliphilidae but is characteristic in bearing the reduced segmentations In legs 1-4, an unusual sexual dimorphism in antennule, and the ventral location of genital areas. Myxomolgus invulgus is readily distinguishable from its congeners by the morphological features of rostrum, antennule, mandible, maxilla, leg 4 and female leg 5.

  • Co-infection with two virus species was previously reported in some cactus plants. Here, we showed that Notocactus leninghausii f. cristatus can be co-infected with six different viruses: cactus mild mottle virus (CMMoV)-Nl, cactus virus X (CVX)-Nl, pitaya virus X (PiVX)-Nl, rattail cactus necrosis-associated virus (RCNaV)-Nl, schlumbergera virus X (SchVX)-Nl, and zygocactus virus X (ZyVX)-Nl. The coat protein sequences of these viruses were compared with those of previously reported viruses. CMMoV-Nl, CVX-Nl, PiVX-Nl, RCNaV-Nl, SchVX-Nl, and ZyVX-Nl showed the greatest nucleotide sequence homology to CMMoV-Kr (99.8% identity, GenBank accession NC_011803), CVX-Jeju (77.5% identity, GenBank accession LC12841), PiVX-P37 (98.4% identity, GenBank accession NC_024458), RCNaV (99.4% identity, GenBank accession NC_016442), SchVX-K11 (95.7% identity, GenBank accession NC_011659), and ZyVX-B1 (97.9% identity, GenBank accession NC_006059), respectively. This study is the first report of co-infection with six virus species in N. leninghausii f. cristatus in South Korea.
