タイトル: Impacts of international trade on the SMT view of the economy著者: Oka, Tosihiro抄録: Shiozawa, Morioka and Taniguchi (2019)'s Microfoundations for Evolutionary Economics (Springer Japan) provided an alternative view (SMT view) of the economy to the orthodox equilibrium view of the economy. According to the SMT view, demand and supply are matched by quantity adjustment under fixed prices, and prices function as a transmitter of cost information downstream as well as a guide for choice and development of techniques. This paper examines the impacts of international trade on the SMT view based on the new theory of international values (NTIV). In a closed economy, prices are uniquely determined even if there are many choices of techniques by the minimal price theorem. With international trade, due to the multiplicity of wages, prices are not uniquely determined. Whether this fact allows demand to participate in the determination of prices is examined, and it is clarified ...

タイトル: Stable carbon and oxygen isotope signatures of mantle-derived calcite in Aitutaki lherzolite xenolith: Implications for organic carbon cycle in the oceanic mantle著者: Akizawa, Norikatsu; Ishimura, Toyoho; Yoshikawa, Masako; Kogiso, Tetsu; Ishikawa, Akira; Mimura, Kazuhide抄録: Carbon isotope data is desired to be increased to promote the understanding of carbon cycle throughout in the Earth. Diamond is a key carbonaceous tool to study deep carbon cycle, but most diamond occurrences are limited from kimberlite pipes in the continental region. Recently, micron-sized diamonds have been discovered from the oceanic region and investigated to understand deep carbon cycle in the oceanic mantle. However, some fundamental cautions have been issued on the oceanic diamonds because some of them could be of artificial origin. Hence, alternative oceanic mantle-derived carbonaceous material is needed to increase oceanic carbon isotope data. We report micron-sized calcite vein in a ...

タイトル: Chimpanzees utilize video as reference in a spatiotemporally distant search for hidden food著者: Xu, Shenwen; Tomonaga, Masaki; Adachi, Ikuma抄録: Referring to things that are displaced in space and time is one of the defining features of human language. In order to better understand the evolution of human language, it is therefore important to explore how widely the ability for displaced reference is shared in animal kingdom. In this study, we explored whether chimpanzees are capable of utilizing video as a displaced reference in a spatiotemporally distant task. We used video to inform chimpanzees about an otherwise unobservable food-hiding. We examined the extent to which chimpanzees would make use of video as a source of information to guide their retrieval of hidden food from a target container. We found that when the event of observing food-hiding and the event of retrieving hidden food were close in space and time within the same room, all chimpanzees solved the ...

タイトル: Evaluation of single silicon vacancy centers in nanodiamonds created by ion implantation at cryogenic temperatures著者: Shimazaki, Konosuke; Suzuki, Kazuki; Sakamoto, Kengo; Okashiro, Yudai; Abe, Hiroshi; Ohshima, Takeshi; Takashima, Hideaki; Takeuchi, Shigeki抄録: Silicon vacancy (SiV) centers in diamonds have attracted much attention because of their stability and narrow emission linewidth, and are promising for applications in quantum information technology. SiV-center-encapsulated nanodiamonds have also attracted much attention because of their potential to be coupled to various photonic devices. One efficient way to fabricate nanodiamonds that contain SiV centers is Si ion implantation into nanodiamonds. However, the evaluation of a single SiV center in a nanodiamond produced by this method at low temperatures has not been performed. In this study, we report on the optical properties of a single SiV center in a nanodiamond produced by ion implantation at cryogeni ...

タイトル: Construction of robust superhydrophobic surfaces with electrothermal, photothermal properties using simple spraying method著者: Chang, Chengbi; Noh, Insub; Zhou, Nan; Jeon, Jihun; Wang, Yanbin; Kim, Hyung Do; Liu, Qingqing; Ohkita, Hideo; Tao, Xinlei; Wang, Biaobing抄録: In this study, robust superhydrophobic surfaces with electrothermal, photothermal properties were fabricated by simple spraying method. In more detail, multiwall carbon nanotube (MWCNT) and silica were deliberately sprayed onto the wet poly(amide imide) (PAI) surface to construct intensive conductive network with hierarchical porous structure. The composite coating showed superhydrophobic with a water contact angle (CA) of greater than 155⁰ and sliding angle (SA) of lower than 5⁰, conductivity of approaching to 1 kΩ sq⁻¹. As expected, the composite coating possessed passive anti-icing property owing to its high CA, and the freezing time at -20 °C was obviously delayed from 150 to 600 s. On th ...

タイトル: Comparison of a Novel Head-Mounted Objective Auto-perimetry (Gaze Analyzing Perimeter) and Humphrey Field Analyzer著者: Miyake, Masahiro; Mori, Yuki; Wada, Saori; Yamada, Kazutaka; Shiraishi, Ryo; Numa, Shogo; Suda, Kenji; Kameda, Takanori; Ikeda, Hanako; Akagi, Tadamichi; Aibara, Teruo; Tamura, Hiroshi; Tsujikawa, Akitaka抄録: Purpose: To evaluate the agreement between 24-2 visual field (VF) test results obtained using the gaze analyzing perimeter (GAP; Findex) and the Humphrey field analyzer (HFA; Carl Zeiss Meditec). Design: Cross-sectional study. Participants: Patients underwent HFA 24-2 for suspected or confirmed VF loss and were treated at the Kyoto University Hospital between December 2022 and July 2023. Methods: Patients underwent consecutive VF tests on the same eye using HFA and GAP 24-2 tests. Bland–Altman analysis was used to compare GAP and HFA results. Examination points where the sensitivity measured using GAP was ≥ 10 dB higher than that measured u ...

タイトル: Therapeutic potential of human induced pluripotent stem cell-derived cardiac tissue in an ischemic model with unloaded condition mimicking left ventricular assist device著者: Heima, Daisuke; Takeda, Masafumi; Tabata, Yasuhiko; Minatoya, Kenji; Yamashita, Jun K.; Masumoto, Hidetoshi抄録: Objective: This study aimed to explore the therapeutic potential of human induced pluripotent stem cell (hiPSC)-derived cardiac tissues (HiCTs) in the emerging approach of bridge to recovery for severe heart failure with ventricular assist devices. We used a rat model of heterotopic heart transplantation (HTx) to mimic ventricular assist device support and heart unloading. Methods: HiCTs were created by inserting gelatin hydrogel microspheres between cell sheets made from hiPSC-derived cardiovascular cells. Male athymic nude rats underwent myocardial infarction (MI) and were divided into the following groups: MI (loaded, untreated control), MI + HTx (unloaded, untreated control), MI + ...
