An Analysis: Quantitative Easing Policy Was Effective in Buoying the Japanese Economy

The Bank of Japan’s quantitative easing policy was introduced in March 2001 and terminated in March 2006. Initially, it was not certain whether the unprecedented policy would succeed, and in a sense, its introduction was experimental. Was the quantitative easing policy effective as a new monetary policy measure? Although many observers have negative views about the effects of the policy, we have attempted to examine its effects using a macro-economic model. In a nutshell, the quantitative easing policy was one in which the operating target of money market operations was shifted from interest rates to a quantitative indicator. The quantitative indicator was the outstanding balance of current accounts held by banks at the Bank of Japan. When this policy was introduced, the central bank also strengthened its commitment by clearly stating that it would continue quantitative easing policy until “the year-on-year rate of change in the consumer price index (CPI) (excluding fresh food) registered zero percent or higher on a sustainable basis.” Quantitative Easing Examined through a Macro-model The following is an examination of the effects of monetary easing on the rea

Shinshu University Distance-Learning Systern using Broadband-Internet via Microwave

In Shinshu University, the campuses are connected by a microwave network called SUNS (Shinshu University Campus Collaboration Network System), in which 7.5 GHz digital microwave with the transmission capacity of 19 Mbps is used. SUNS is mainly composed of two networks: one is a video and audio data network with bilateral communication and other is a computer data network. Distance learning system applying SUNS is widely used for intercampus- and interuniversity- lectures, extension lectures, meetings and conferences. In this paper, the network system configurations of SUNS and its application to the distance learning are introduced.Article信州大学教育システム研究開発センター紀要 6: 87-96(2000)departmental bulletin pape

Lung Cancer Associated with Sarcoidosis - A case report -

Sarcoidosis is a somewhat common pulmonary disease, but the concurrence of lung cancer and sarcoidosis in the same patient is very rare. Because sarcoidosis usually presents as mediastinal lymphadenopathies, this concurrence in a lung cancer patient detected radiologically is apt to be misunderstood to be mediastinal metastases, and it is thus considered to be an unresectable disease. We report a case of lung cancer associated with sarcoidosis that developed in a 65-year-old woman who underwent surgery. Radiological studies revealed a 1.9×1.7 cm mass in the left upper lobe with multiple enlarged bilateral mediastinal lymph nodes (2R, 3a, 4R, 4L, 5, 6, 7, 8R). Pathologic findings showed that the mass was a well-differentiated adenocarcinoma and all of the enlarged mediastinal lymph nodes were granulomas without cancer metastasis. We report this case with a review of the literature

Strain sensor using stress-magnetoresistance effect of Ni-Fe/Mn-Ir exchange-coupled magnetic film

The following article appeared in JOURNAL OF APPLIED PHYSICS. 107(9):09E718 (2010) and may be found at https://doi.org/10.1063/1.3362902 .A strain sensor using a stress-magnetoresistance effect of a Ni-Fe/Mn-Ir exchange-coupled magnetic film was fabricated and evaluated. The stress magnetoresistance is used in the inverse magnetostrictive effect and the magnetoresistance effect in the magnetic film since an external stress is changed into an electric resistance in it. A compressive stress was measured by the strain sensor with a Mn-Ir (10 nm)/Ni-Fe (50 nm)/Ru (1 nm) exchange-coupled film. The change in resistivity Delta rho/rho is proportional to the applied compressive stress sigma for sigma <= 50 MPa in the strain sensor. When increasing Ni-Fe layer thickness in the strain sensor, a gauge factor increased.ArticleJOURNAL OF APPLIED PHYSICS. 107(9):09E718 (2010)journal articl

A Case of Vascular Graft Infection Caused by Staphylococcus lugdunensis after Femoropopliteal Bypass Operation

A 79-year-old man who had undergone a right femoropopliteal (FP) bypass operation 6 weeks previously was diagnosed with vascular graft infection caused by Staphylococcus lugdunensis. Another FP bypass operation was performed, with long-term administration of antibiotics, and the patient eventually recovered well without any recurrences for over 2 years. Although S. lugdunens is classified as coagulase-negative Staphylococcus, its pathogenicity has been reported to be equal to that of S. aureus. Based on the literature review, the organism characteristically colonizes the inguinal area of human skin;thus, operations such as FP bypass grafting may place patients at a relatively high risk for infection by S. lugdunensis, a potentially high-pathogenicity organism

Cross-Talk Suppression in High-Density Printed Circuit Boards Using Magnetic Composite Filled in Spacing Between Signal Lines

Recently, high-density printed circuit boards (HD-PCBs) with less than 50 mum/50 mum line/space has been developed. In the HD-PCB, since the spacing between adjacent signal lines becomes very small, the crosstalk electromagnetic interference among adjacent lines becomes serious. In general, in order to suppress the crosstalk, the ground line is located at the spacing between signal lines because of the decrease of mutual capacitance among adjacent signal lines. The authors have proposed a magnetic method for reducing the crosstalk. The composite magnetic material was filled in the spacing between signal lines instead of the ground line. The magnetic composite is composed of Fe-Si-B-Cr amorphous particles with a mean diameter of 6 mu m and epoxy resin. From the experiments using the PCB-TEG with a 130 mum/50 mum line/space and 25-mm line length, the crosstalk was suppressed in the wide frequency range by using the magnetic composite. In the case of using 51 vol.% amorphous composite, the crosstalk suppression was up to 20 dB around 1 GHz. The influence of the magnetic composite on the transmission and reflection in the main signal line was very small. Therefore, the proposed method is effective for crosstalk suppression without influence on the signal transmission.ArticleIEEE TRANSACTIONS ON MAGNETICS. 45(10):4801-4803 (2009)journal articl

Complexity reduction of astrochemical networks

We present a new computational scheme aimed at reducing the complexity of the chemical networks in astrophysical models, one which is shown to markedly improve their computational efficiency. It contains a flux-reduction scheme that permits to deal with both large and small systems. This procedure is shown to yield a large speed-up of the corresponding numerical codes and provides good accord with the full network results. We analyse and discuss two examples involving chemistry networks of the interstellar medium and show that the results from the present reduction technique reproduce very well the results from fuller calculations.Comment: 9 pages, 7 figures, accepted for publication in Monthly Notices of the Royal Astronomical Society Main Journa
