Discovery of the Yamato Meteorites in 1969
No full textAbstractThe first discovery of Yamato Meteorites by an inland survey team of the Japanese Antarctic Research Expedition (JARE) in 1969 was reported by Yoshida et al. (1971). However, there are important events, issues, and data related to this discovery that have so far not been published. Prior to the author's departure for Antarctica, M. Gorai suggested the author to consider collecting meteorites during the trip. On 21 December 1969, when geodetic measurements for the 250 km span of a triangulation chain were approaching its completion, members of the inland survey team collected three stones on the surface of the ice sheet in the southeastern marginal area of the Yamato Mountains. The author realized that these rocks were possibly meteorites, recalled the suggestion by M. Gorai, and requested all members of the team to collect other possible meteorites while conducting the geodetic survey. After returning to Japan, the nine stones collected in Antarctica were all identified as meteorites by M. Gorai. The concept of a mechanism by which meteorites became concentrated in the area in which they were found, involving the flow, structure, and ablation of the ice sheet, was developed in the field in 1969 during the collection program, and was mentioned briefly in Yoshida et al. (1971); a schematic figure was shown in a Japanese newspaper in the same year. With all these as background, further collections of meteorites in the Yamato Mountains were conducted in the 1973 and 1974–1975 seasons, and a project involving the collection of meteorites was formally incorporated as an important component of the work undertaken by the geology group within JARE from the 1975–1976 season onwards
A Novel Teleoperated Hybrid Wheel-Limb Hexapod for Lunar Craters' Exploration
No full textSuccessful robotic planetary exploration missions are not without technical and scientific challenges. Appropriate control and mobility of the robot is critical for successful exploration in unstructured environments. We address these problems through an overview of an under development telerobotic platform for exploration missions to the lunar craters. The platform is based on a novel transforming hybrid walking/roving Lunar Exploration Omnidirectional Netbot (LEON). We describe a versatile dynamic engine based simulator/teleoperation platform called ERode (Eric Rohmer Open Dynamic Engine), which allows developing, simulating and teleoperation of LEON. We also introduce the novel hybrid wheel/limb design of LEON, whereby two of its six limbs fold into themselves transforming into wheels. This possibility of transformation results in increased mobility in the environment, by adapting to different soil conditions. Furthermore, this system has a limited bulkiness compared to hybrid systems owning both wheels and legs, and it has an increased wheel diameter compared to hybrid systems having wheels at the tip of their legs. Preliminary experimental or simulated results are also presented, showing the performance of the hybrid system dealing with different types of terrain

Fujii, M. Ozaki, K. Yoshino, H. K. Kim and N. S. Baek, S. K. Choi, Journal of Applied Physics 95, 4193 (2004) and may be found at https://doi.org/10.1063/1.1667272.Optical properties of conducting polymers with Sn atoms in main chains, such as optical absorption, photoluminescence (PL), and electroluminescence, have been studied. The electronic energy structures have been determined by optical and electrochemical measurements. Strong PL with high quantum efficiency has been clarified in the films, and photopumped multimode laser emission was demonstrated from cylindrical microcavities formed by these polymers coated around optical fibers
Mechanochromic Switching between Delayed Fluorescence and Phosphorescence of Luminescent Coordination Polymers Composed of Dinuclear Copper(I) Iodide Rhombic Cores
No full textThe synthesis and photophysical properties of two luminescent Cu-I coordination polymers, [Cu2I2(PPh3)(2)(3-tpyb)](n) and [Cu2I2(PPh3)(2)(4-tpyb)](n) (Cu-3-tpyb and Cu-4-tpyb; PPh3=triphenylphosphine, m-tpyb=1,3,5-tris(m-pyridyl)benzene (m=3, 4)), are described. X-ray structural analysis indicated that one-dimensional coordination chains comprising rhombic {Cu2I2(PPh3)(2)} cores and m-tpyb bridging ligands were formed. Both Cu-3-tpyb and Cu-4-tpyb exhibited blue-to-yellow thermally activated delayed fluorescence (TADF) that originated from mixing of the metal-to-ligand and halide-to-ligand charge-transfer excited states and moderate emission quantum yields of 0.29 and 0.27, respectively, at 298K. Further, mechanochromic luminescence was observed for both complexes. The emission lifetimes indicated that the origin of emission switched from TADF to phosphorescence, which was derived from the triplet cluster-centered ((CC)-C-3) emissive state generated by grinding-induced amorphization
Shift in disparities in Hepatitis C treatment from interferon to DAA era: A population-based cohort study
No full textWe evaluated the shift in the characteristics of people who received interferon-based hepatitis C virus (HCV) treatments and those who received recently introduced direct-acting antivirals (DAAs) in British Columbia (BC), Canada. The BC Hepatitis Testers Cohort includes 1.5 million individuals tested for HCV or HIV, or reported cases of hepatitis B and active tuberculosis in BC from 1990 to 2013 linked to medical visits, hospitalization, cancer, prescription drugs and mortality data. This analysis included all patients who filled at least one prescription for HCV treatment until 31 July 2015. HCV treatments were classified as older interferon-based treatments including pegylated interferon/ribavirin (PegIFN/RBV) with/without boceprevir or telaprevir, DAAs with RBV or PegIFN/RBV, and newer interferon-free DAAs. Of 11 886 people treated for HCV between 2000 and 2015, 1164 (9.8%) received interferon-free DAAs (ledipasvir/sofosbuvir: n=1075; 92.4%), while 452 (3.8%) received a combination of DAAs and RBV or PegIFN/RBV. Compared to those receiving interferon-based treatment, people with HIV co-infection (adjusted odds ratio [aOR]: 2.96, 95% CI: 2.31-3.81), cirrhosis (aOR: 1.77, 95% CI: 1.45-2.15), decompensated cirrhosis (aOR: 1.72, 95% CI: 1.31-2.28), diabetes (aOR: 1.30, 95% CI: 1.10-1.54), a history of injection drug use (aOR: 1.34, 95% CI: 1.09-1.65) and opioid substitution therapy (aOR: 1.30, 95% CI: 1.01-1.67) were more likely to receive interferon-free DAAs. Socio-economically marginalized individuals were significantly less likely (most deprived vs most privileged: aOR: 0.71, 95% CI: 0.58-0.87) to receive DAAs. In conclusion, there is a shift in prescription of new HCV treatments to previously excluded groups (eg HIV-co-infected), although gaps remain for the socio-economically marginalized populations

No full textThis article may be downloaded for personal use only. Any other use requires prior permission of the author and AIP Publishing. This article appeared in Y. Yoshida, T. Nishimura, A. Fujii, M. Ozaki, and K. Yoshino, Appl. Phys. Lett. 86, 141903 (2005) and may be found at https://doi.org/10.1063/1.1899229.We have demonstrated photopumped multimode laser emission from cylindrical microcavities of conducting polymer thin films, which were formed by deposition on the inside surface of the glass microcapillary with capillary action. The laser emission was characterized by narrow emission lines and a well-defined excitation threshold. We also fabricated dual ring cavities on inner and outer surfaces of microcapillaries, and laser emission from both sides of capillaries was observed by photopumping with one excitation source. Fabricating two cylindrical microcavities on inner and outer surfaces of the microcapillary by utilizing a different sort of conducting polymers, dual laser emissions, blue and red in color, were obtained concurrently. This work was partly supported by the Industrial Technology research Grant Program in ’04 from the New Energy and Industrial Technology Development Organization (NEDO) of Japan, and grant-in-aid for JSPS fellows of the Ministry of Education, Culture, Sports, Science, and Technology
Type and Effect Systems for Dynamically Changing Code - DRAFT CORRECTIONS, DO NOT DISTRIBUTE
No full textWe extend type and effect analyses to permit dynamically changing effects and dynamically changing code in multi-threaded systems with shared resources. We guarantee that after a well typed modification a set of threads will have the specified desired effects and will continue to safely use the resources. We prove the key properties of subject reduction and fidelity (safety) for our general system. We provide an application of our system: dynamic software updating for a multi-threaded asynchronous message passing system. We show how key safety properties from session typing follow from the properties of our general system
