Identification of the Tandem Running Pheromone in Diacamma sp. from Japan (Hymenoptera, Formicidae)
Autor: Naoki Fujiwara Tsujii, Kotone Tokunaga, Toshiharu Akino, Kazuki Tsuji, Ryohei Yamaoka
Publikováno v: Sociobiology, Vol 59, Iss 4 (2014)
The Japanese queenless ponerine ant Diacamma sp. from Japan employs tandem running during nest relocation, in which a leader ant guides nestmate followers one at a time. We replicated this process by presenting one entire abdominal part of a leader,

Publikováno v: PLoS ONE, Vol 9, Iss 1, p e86054 (2014)
Regulation via interspecific communication is an important for the maintenance of many mutualisms. However, mechanisms underlying the evolution of partner communication are poorly understood for many mutualisms. Here we show, in an ant-lycaenid butte

10-4: A 13.3-inch 8K x 4K 664-ppi 120-Hz 12-bit Display with Super-wide Color Gamut for the BT.2020 Standard
Autor: Roh Yamamoto, Ryohei Yamaoka, Toshiki Sasaki, Kei Takahashi, Daiki Nakamura, Shunpei Yamazaki, Shiho Nomura, Hisao Ikeda, Satoshi Seo, Tomoya Aoyama
Publikováno v: SID Symposium Digest of Technical Papers. 48:123-126
Newly developed light-emitting materials and device structure achieved a highly efficient long-lived white tandem OLED with saturated RGB spectra for a wider color gamut. By combining the OLED devices with a color filter and top emission structure, w

52-4: Long-lived Thermally Stable Blue OLED Achieving BT.2020 Color Gamut
Autor: Takita Yusuke, Shiho Nomura, Hashimoto Naoaki, Sachiko Yamagata, Ryohei Yamaoka, Satoshi Seo, Tsunenori Suzuki, Toshiki Sasaki
Publikováno v: SID Symposium Digest of Technical Papers. 48:786-789
We developed a deep-blue fluorescent organic light-emitting diode (OLED) that is long-lived and thermally stable. This blue OLED accommodates the BT.2020 color gamut for the first time in the world, and enables a longer lifetime than a conventional o

3-4: Ultra-wide Color Gamut OLED Display using a Deep-red Phosphorescent Device with High Efficiency, Long Life, Thermal Stability, and Absolute BT.2020 Red Chromaticity
Autor: Shiho Nomura, Tomoya Yamaguchi, Shunsuke Hosoumi, Toshiki Sasaki, Hideko Inoue, Satoshi Seo, Ryohei Yamaoka
Publikováno v: SID Symposium Digest of Technical Papers. 48:13-16
We developed a deep-red phosphorescent organic light-emitting diode (OLED) with (x, y) chromaticity coordinates of (0.709, 0.290), high external quantum efficiency of 27.4%, and higher stability than a conventional red OLED. This device realizes an O
