Nishida Institute of Spaceand AstronauticalScience, Kanagawa, Japan H. Fukunishi Department of Geophysicsand Astrophysics,Tohoku University,Sendai, Japan Center for Atmosphericand SpaceSciences, Utah State University,Logan Abstract. Akebono (Exos D) observationsdemonstrate that polar cap arcssometimes have a fine structure,that is, multiple (doubleor triple) arcswith spacingof a few tens of kilometers.The multiplepolar cap arcsare dominantlyobserved in the nightsidepolar cap region, suggestingthat low backgroundconductance favors the appearanceof the structuredarcs. A relationshipbetween the spacingand the averageenergy of the precipitatingelectrons is investigated.Results show that a higher energyleads to a wider spacing.Akebono observationsalso showthe existenceof a downwardcurrent region embeddedbetween upward current regions (arcs). Comparison of the observationswith resultsfrom a coupledmagnetosphere-ionosphere Sun-aligned arc model is made, which showsgood qualitativeagreement between the modelingand observationalresults on the spacing-energydependence and the effect of backgroundionospheric conductance.

The complex nature of magnetospheric processes cause a wide range of dynamic variations in the auroral zone, which are difficult to forecast. Knowledge of electron concentrations in this highly turbulent region is of particular importance because it determines the propagation conditions for the radio waves. In this work we introduce the numerical model of the auroral E-region, which evaluates density variations of the 10 ionospheric species and 39 reactions initiated by both the solar extreme UV radiation and the magnetospheric electron precipitation. The chemical reaction rates differ in more than ten orders of magnitude, resulting in the high stiffness of the ordinary differential equations system considered, which was solved using the high-performance Gear method. The AIM-E model allowed us to calculate the concentration of the neutrals NO, N(4S), and N(2D), ions + + + + + 4 + 2 + 2 N ,N2 , NO ,O2 ,O ( S), O ( D), and O ( P), and electrons Ne, in the whole auroral zone in the Citation: Nikolaeva, V.; Gordeev, E.; 90-150 km altitude range in real time. -

National Cancer Center Japan Construction Begins on the “Kashiwa-no-ha Hotel Project (tentative name)” to Create a New Clinical Model in Kashiwa-no-ha = Scheduled to Open a Hospital-Linked Accommodation Facility in Summer 2022 to Support Cancer Treatment and Research = Tokyo, JAPAN – December 22, 2020 – Mitsui Fudosan Co., Ltd., a leading global real estate company headquartered in Tokyo, and National Cancer Center Japan (Headquarters: Chuo-ku, Tokyo; President: Hitoshi Nakagama; “NCC”) announced today the start of construction of the “Kashiwa-no-ha Hotel Project (tentative name)” on December 16 on the grounds of the National Cancer Center Hospital East (Location: 6-5-1 Kashiwanoha, Kashiwa, Chiba, Japan; Director: Atsushi Ohtsu, “NCC Hospital East”). With this project, Mitsui Fudosan will lease a part of the grounds of NCC Hospital East and construct a hotel (total number of guest rooms planned: 146) on the site. After completion, Mitsui Fudosan Hotel Management Co., Ltd. (Headquarters: Chuo-ku, Tokyo; President and CEO, Masaru Sasabe; “Mitsui Fudosan Hotel Management”) will operate the hotel, to open in summer 2022. The development is on the premises of NCC Hospital East, six minutes by bus from Kashiwanoha-campus Station on the Tsukuba Express Line. NCC Hospital East, one of the leading specialized cancer hospitals in Japan, treats nearly 300,000 cancer patients a year from both Japan and overseas. There are cases where patients must undergo regular outpatient treatment for a certain period of time, or where patients must travel from afar to undergo inpatient or outpatient treatment. -

UNCLASSIFIED/UNLIMITED The International Reference Ionosphere – Climatological Standard for the Ionosphere Dieter Bilitza Raytheon IS, Space Physics Data Facility GSFC, Code 612.4 Greenbelt, MD 20771 U.S.A. [email protected] ABSTRACT The International Reference Ionosphere (IRI) a joint project of URSI and COSPAR is the defacto standard for a climatological specification of ionospheric parameters. IRI is based on a wide range of ground and space data and has been steadily improved since its inception in 1969 with the ever-increasing volume of ionospheric data and with better mathematical descriptions of the observed global and temporal variation patterns. The IRI model has been validated with a large amount of data including data from the most recent ionospheric satellites (KOMPSAT, ROCSAT and TIMED) and data from global network of ionosondes. Several IRI teams are working on specific aspects of the IRI modeling effort including an improved representation of the topside ionosphere with a seamless transition to the plasmasphere, a new effort to represent the global variation of F2 peak parameters using the Neural Network (NN) technique, and the inclusion of several additional parameters in IRI, e.g., spread-F probability and ionospheric variability. Annual IRI workshops are the forum for discussions of these efforts and for all science activities related to IRI as well as applications of the IRI model in engineering and education. In this paper I will present a status report about the IRI effort with special emphasis on the presentations and results from the most recent IRI Workshops (Paris, 2004; Tortosa, 2005) and on the most important ongoing IRI activities. -

We expanded the frequency sweep range in order to cover large Doppler shift on orbit. The GPS receiver was modified to output pseudorange data with accurate time tag. We tested the performance in low earth orbits by means of a GPS simulator. The range error caused by the receiver is measured to be 0.9 meter in RMS. Receiver was on-boarded on INDEX (“REIMEI”) satellite, which was launched in 2005. Cold start positioning was confirmed repeatedly to finish within 30 minutes on orbit. The orbit determination was performed to evaluate the random position error of GPS receiver by means of the residual error. The random error of GPS position is as large as 2 meter for PDDP=2.5 on orbit. The RMS value of range error is evaluated to be 0.6m from the flight data. -
UCLA Japan Center Opened in Kashiwa-No-Ha (Kashiwa City, Chiba) ======Tokyo, Japan, June 20 2016,Mitsui Fudosan Co., Ltd
Press release June 20, 2016 Mitsui Fudosan Co., Ltd. UCLA (University of California, Los Angeles) =========================================================================================== UCLA Japan Center Opened in Kashiwa-no-ha (Kashiwa City, Chiba) =========================================================================================== Tokyo, Japan, June 20 2016,Mitsui Fudosan Co., Ltd. and UCLA (University of California, Los Angeles) announced the opening of the UCLA Japan Center in Mitsui Fudosan’s “31VENTURES KOIL” in Kashiwa-no-ha Smart City, which promotes urban development through public-private-academic partnership. On June 16, UCLA Chancellor Gene Block and related personnel arrived in Japan and after holding discussions with urban development personnel at Kashiwa-no-ha Smart City, held an inaugural reception. The UCLA Japan Center was founded as a memorial project for the 100th anniversary of UCLA in 2019 and will serve as a point of contact for UCLA in Japan, a Japan Alumni Association office and a Japan base for UCLA researchers. UCLA chose this location because it endorses Kashiwa-no-ha Smart City’s concept of urban development to create problem-solving models for the world and 31VENTURES KOIL’s concept of business creation through open innovation, both based on public-private-academic partnership. With such a location as the stage, a major goal of the center is to be a base of exchange that contributes to enhancing international relations between Japan and the rest of Asia as well as the U.S. and promoting mutual -
