List of Polypores and Other Aphyllophoraceous Fungi Collected in the Lambir Hills National Park, Sarawak, Malaysia

We collected 933 specimens of polypores and other aphyllophoraceous fungi in the Lambir Hills National Park, Sarawak, Malaysia, in 2006. We identified 848 specimens and recorded 57 species and 59 morphospecies. We compare our list to the results of a few former floral studies conducted in and near the park

Electroencephalogram Analysis Regarding Visual Information Processing in a Grapheme-color Synesthete

In order to explore characteristics of visual information processing in grapheme-color synesthesia, we examined behavior (response correctness and reaction time) and temporal activities of EEG during the performance of two kinds of "embedded shape tasks" in one synesthete and 16 nonsynesthetic subjects. We used three black capital letters, including one letter which a synesthetic subject perceived in color. The target grapheme was made of a letter which a synesthetic subject perceived in color (TASK1), and one that was not perceived in color (TASK2). There was a significant difference in reaction time between the two tasks. Measuring the difference in amplitude of EEG activity at P4 between the two tasks, biphasic activity change was observed. At 232.5 ms in the late phase, the bilateral occipital and parietal lobes, and the left frontal lobe were activated. These results suggest that biphasic activity change is related to different visual information processing in synesthesia; the early phase is related to directing attention to a shape with color, while the late phase to the recognition of a shape with color. It is also suggested that activated areas of the brain in the late phase function separately in causing grapheme-color synesthesia

High-Tc ramp-type Josephson junctions on MgO substrates for Terahertz applications

The authors successfully fabricated high-Tc ramp-type junctions with PrBa2Cu3-xGaxO7-δ (PBCGO: x=0.1, 0.4) barriers on MgO substrates. The junctions showed resistively shunted Josephson junction (RSJ)-like I-V curves with thermally and voltage activated conductivity. The IcRn products for these junctions scaled very well with the Ga-doping. Maximum response of the junctions for 100-GHz millimeter-wave irradiation could be observed up to 12 mV corresponding to 6 THz. Using far infrared laser radiation, we confirmed a terahertz (THz) response of these junctions. These results show promise for THz-wave applications of ramp-type Josephson junctions
