Satellite-based vegetation monitoring provides important insights regarding spatiotemporal variations in growth from a regional to continental scale. Most current methodologies rely on spectral indices (VIs) observed by polar-orbiting satellites, which provide one or few observations per day. This study proposes new methodology based diurnal changes land surface temperatures (LSTs) using Japan's geostationary satellite, Himawari-8/Advanced Himawari Imager (AHI). AHI thermal infrared...
Recent advancements in new generation geostationary satellites have facilitated the application of their datasets to terrestrial monitoring. In this application, geolocation accuracy is an essential issue because land surfaces are generally heterogeneous. case Advanced Himawari Imager (AHI) onboard Himawari-8, geometric correction Standard Data provided by Japan Meteorological Agency (JMA data) was conducted using thermal infrared band with 2 km spatial resolution. Based on JMA data, Center...
Sex differences were observed in host resistance to Mycobacterium marinum infection mice. Males found be more susceptible than females terms of mortality, incidence gross skin lesions, and bacterial load the lungs spleen. The degree sex varied from strain test mice, order C3H/He, A/J, BALB/c greater DBA/2, B10.A, C57BL/6, on basis survival time multiplication organisms visceral organs. Although this ordering corresponded susceptibilities both male female mice organisms, much dependency was...
This paper presents a method for estimating the land surface temperature (LST) from Himawari-8 data. The Advanced Himawari Imager onboard has three thermal infrared bands in spectral range of 10-12.5 μm. We developed nonlinear three-band algorithm (NTB) that makes best use these to estimate LST. formula includes 10 coefficients. optimum values coefficients were derived using statistical regression simulated data, as obtained by radiative transfer model. data sets correspond variety LST, well...
Satellite remote sensing with the third-generation geostationary satellites has recently gained significant attention. These provide hyper-temporal datasets, enabling mitigation of cloud contamination effects and observation diurnal changes in targets, contrast to polar-orbiting satellites. Currently, several satellites, such as Japanese Himawari series, US GOES Korean GK2A, Chinese FY4 European MTG1, have been under operation, their datasets are available. In cover limited areas Earth due...
ABSTRACT We examined retrospectively 61 eyes of patients with recurrent pterygia who had been treated excision, or without 0.02% mitomycin C instillation, 3 to 7 years after treatment. The rates recurrence (5% 9%) and complications in that undergone excision instillation were less than those only. These data suggest the postoperative C, twice a day for five days, may be effective safe treatment pterygium.
Dawn and dusk land surface temperature (LST) is important for constructing sub-daily LSTs understanding diurnal cycles. In this study, a dawn-dusk LST was developed using the Medium Resolution Spectral Imager-Low Light (MERSI-LL) instrument onboard Fengyun-3E (FY-3E). A emissivity separation (TES) algorithm first implemented three thermal infrared (TIR) bands of MERSI-LL. The retrieved validated against in-situ measurements at 46 sites. An RMSE 2.07 K obtained vegetated surfaces, while large...
Abstract Understanding the land cover is crucial to comprehending functioning of Earth’s system. The Siberia characterized by uncertainty because it wide-ranging and comprises various classification types. However, comparisons among products reveal substantial discrepancies uncertainties. Therefore, a reliable product for necessary. In this study, we generated new data using random forest (RF) classifiers with global datasets. To assess their accuracy characteristics, individually validated...
Evapotranspiration (ET) and Gross Primary Productivity (GPP) are fundamental variables on land surfaces, important for understanding the response of vegetation surfaces to extreme weather. In particular, third-generation geostationary meteorological satellites such as Himawari-8/9 effective monitoring, they include observations wavelength bands including visible near-infrared light every 10 minutes. addition, if used, monitoring with high temporal resolution 30 minutes can be done in...
Himawari-8, a new-generation geostationary satellite, can retrieve sub-hourly land surface temperatures (LSTs) with moderate spatial resolution, providing new scale for monitoring the thermal environment in Asia and Oceania. This study evaluated uncertainties of LSTs retrieved by three operational algorithms from Advanced Himawari Imager (AHI) data. We compared two nonlinear split-window (SOB WAN algorithms) one three-band algorithm (YAM algorithm). First, error characteristics caused input...
Land surface emissivity (LSE) in the thermal infrared (TIR) is an essential parameter retrieving land temperature (LST) from space. This paper describes LSE maps three TIR bands (centered at 10.4, 11.2 and 12.4 μm) used for LST Himawari-8. Himawari-8, a next-generation geostationary satellite has high spatial temporal resolutions compared to previous satellites. Because of these improvements, Himawari-8 product expected contribute observation small-scale environments high-frequency. In this...
An amorphous-metal-oxide-semiconductor (AOS) thin-film planar-type spike-timing-dependent-plasticity (STDP) synapse device has been developed. The AOS is a non-rare material and can be easily deposited, therefore it inexpensive. On the other hand, STDP promising as learning principle for neuromorphic systems.

MU radar‐RASS observations were conducted on July 28–31, 1994 at Shigaraki, Japan (35°N, 136°E), to determine the detailed time variations of all three wind components and virtual temperature in lower troposphere. We discuss their frequency spectra comparison with a theoretical model gravity waves. Assuming hydrostatic equilibrium, we also estimated vertical velocity from derivative each altitude. found that derived more consistent wave than those calculated direct measurements wind.

高度経済成長期に建設された多くの高架道路橋は老朽化を迎えているため維持管理が必要である．しかし，これらの高架道路橋は，設計時や竣工時の図面が紙媒体であり，廃棄されているケースが多く維持管理業務に支障をきたしている．そこで，MMSの点群データから高架道路橋の維持管理用のSXF図面を自動生成する研究がなされている．既研究では，高架道路橋の継ぎ手の位置で点列を分割しスパンごとに道路橋の線形を生成している．しかし，継ぎ手を抽出できない場合や設計図に記載された線形の起終点が継ぎ手の位置から離れている場合，生成したクロソイド曲線と直線や円弧との連続性が失われる問題がある．そこで，本研究では，平面の直線，クロソイド曲線，円弧と縦断面の直線と２次曲線の起終点を算出し，各線形を連続に接続する解析手法を提案する．それにより，継ぎ手の情報なしで，高架道路橋上部工のSXF図面を高精度に生成することを実現する．
