The Life of Daniel Ken Inoue－The Light and Shadow of The First Senator of Japanese American-
No full textThe famous Japanese American,Daniel Ken Inoue died in December,2012.He lost his arm during World War Ⅱ.He fought for the United State of America.He volunteered to enter 442 troop ?united by only Japanese Americans.He fought because he wanted to protect their honor ?the honor as the Japanese American.He wanted to be admitted that Japaneseamerican as same as white Americans, because he lost his right arm,he lost his dream to become a doctor.So he became a lawyer.But when he was the student,he was interested in polics.He became the first senator from Japanese American with difficulty. President Obama told he became the politician after he knew Daniel Inoue.He belonged to minority as black American,but he could make his dream come true.Since Japanese had immigrated to the United States of America,they had had many difficulties,But they tried to solve their problems patiently. This time I studied the life of Daniel Inoue,and I could learn about of the real life of Japanese Ameicanc in Hawai. As Presisent Obama said,he is the hope of mainolities

Lecideoid lichens of Prince Olav Coast and Soya Coast, Enderby Land, East Antarctica
No full textFive species of lecideoid lichens belonging to three genera are reported as new to the flora of the Prince Olav Coast and the Soya Coast, Enderby Land, East Antarctica; they are Carbonea capsulata (DODGE & BAKER) HALE, Lecidea andersonii R. FILSON, Lecidea cancriformis DODGE & BAKER, Lecidea soyaensis M. INOUE and Lecidella siplei (DODGE & BAKER) M. INOUE. All are endemic to Antarctica. An examination was made of the collections from the region, which were collected mainly by the author under the project of the 27th Japanese Antarctic Research Expedition (JARE-27,during January 1986 and February 1987). The type and authentic specimens of possibly related species have been restudied. Lecidea soyaensis M. INOUE is new to science and Lecidella siplei (DODGE & BAKER) M. INOUE is proposed as a new combination. Taxonomic and chemical data as well as a key to the known taxa are provided

The Hobby of Electronic Circuit Engineering
No full textThis website (originally created in Japanese and translated into English using translation software) by a Japanese systems engineer, Seiichi Inoue, provides an extensive overview of electronic circuit engineering. Topics covered include: Basic knowledge of Electronic parts, Basic knowledge of Engineering Instruments, an Introduction of Engineering Method, and the Assembly Process. A variety of electronic circuits and their uses are provided, as well as a separate section on PIC electronic circuits. The language may be difficult to follow at times given the translation, but still a gem of a site for anyone wanting to build some circuits! Keep in mind that in some sections, the author notes that he is "describing while studying, there seems to be mistakes in the contents. Do at your own risk." For some further browsing, he includes sections on his other interests, such as 3D photography, java programming, CAD, Japanese customs and the Japanese language

Kurbatov (1990) reported that specimens of <i>Tyrodes segrex</i> were collected under moss on maple trees. The first author also collected many individuals from similar habitats in Aomori-ken, Japan (Fig. 4A–C). Furthermore, the first author found many walking males on the surfaces of trees in Aomori-ken and Ôita-ken in June (Fig. 4D, E). Female individuals are found under the moss. Only two individuals were collected with <i>Lasius fuliginosus</i> -group sp. ants (as proposed by Boudinot <i>et al.</i> 2022), but these individuals were possibly collected accidentally with the ants (Kamezawa & Nomura 2012).</p> <p> <b>Comments.</b> This species distributed in the wide range of mainland Japan from Hokkaido to Miyazaki-ken, Kyushu and no other <i>Tyrodes</i> species is found from the region.

But we have not checked the specimen.</p>Published as part of <i>Inoue, Shota & Nomura, Shûhei, 2023, New species and record of Tyrodes Raffray (Coleoptera: Staphylinidae: Pselaphinae) from Japan, pp. 83-92 in Zootaxa 5375 (1)</i> on pages 84-87, DOI: 10.11646/zootaxa.5375.1.4, <a href="http://zenodo.org/record/10170174">http://zenodo.org/record/10170174</a>
GR-RMHD Simulations of Super-Eddington Accretion Flows onto a Neutron Star with Dipole and Quadrupole Magnetic Fields
No full textAlthough ultraluminous X-ray pulsars (ULXPs) are believed to be powered by super-Eddington accretion onto a magnetized neutron star (NS), the detailed structures of the inflow–outflow and magnetic fields are still not well understood. We perform general relativistic radiation magnetohydrodynamics (GR-RMHD) simulations of super-Eddington accretion flows onto a magnetized NS with dipole and/or quadrupole magnetic fields. Our results show that an accretion disk and optically thick outflows form outside the magnetospheric radius, while inflows aligned with magnetic field lines appear inside. When the dipole field is more prominent than the quadrupole field at the magnetospheric radius, accretion columns form near the magnetic poles, whereas a quadrupole magnetic field stronger than the dipole field results in the formation of a belt-like accretion flow near the equatorial plane. The NS spins up as the angular momentum of the accreting gas is converted into the angular momentum of the electromagnetic field, which then flows into the NS. Even if an accretion column forms near one of the magnetic poles, the observed luminosity is almost the same on both the side with the accretion column and the side without it, because the radiation energy is transported to both sides through scattering. Our model suggests that galactic ULXP Swift J0243.6+6124 has a quadrupole magnetic field of 2 × 10 ^13 G and a dipole magnetic field of less than 4 × 10 ^12 G
Comparison of GaN HEMT Technology Processes by Large-Signal Low-Frequency Measurements
No full textIn this paper, we discuss the comparison of two GaN HEMT technology processes by means of large-signal low-frequency (LF) measurements. LF load line analysis clarified the increase of output power and drain efficiency resulting from significant improvement of both knee voltage and maximum drain current by a modified technology process. The cross-check on this advantage was carried out by means of commonly adopted high-frequency load-pull measurement setups

Analysis of Gate-Voltage Clipping Behavior on Class-F and Inverse Class-F Amplifiers
No full textThis paper describes the influence of gate-voltage clipping behavior on drain efficiency in case of class-F and inverse class-F operations under saturated regime. Numerical analysis using a simplified transistor model was carried out. As a result, we have demonstrated that the limiting factor for mathbfclass -mathbfF -1 operation is the gate-diode conduction rather than knee voltage. On the other hand, class-F PA is restricted by the knee voltage effects. Furthermore, nonlinear measurements carried out on a GaN HEMT support our analytical results
