This paper reviews theoretical calculation of ELNES using first principles band structure methods. A core-hole is included in the calculation, and the matrix elements of the electric dipole transition between the ground state and the final state are computed. The satisfactory reproductions of the experimental spectra are commonly brought about by employing the sufficient large supercells. The orientation dependence of ELVES for wurtzite-A1N is discussed. The dependence was found to be much larger in K edges as compared to the L2.3 edge. The large projection dependence is predicted in O-K ELNES of SrTiO3. It was found that those spectral changes according to the position of the projection are caused by the unidirectional Ti-O-Ti bond in SrTiO3. Theoretical calculation of the low loss spectrum from SrTiO3 is also discussed.

The purpose of the study was to investigate the degree of subject variability in the peripheral and core temperature thresholds of the onset of shivering and sweating. Nine healthy young male subjects participated in three trials. In the first two trials, wearing only shorts, they were exposed to air temperatures of 5°C and 40°C until the onset of shivering and sweating, respectively. In the second experiment, subjects wore a water perfused suit that was perfused with 25°C water at a rate of 600 cc/min. They exercised on an ergometer at 50% of their maximum work rate for 10–15 min. At the onset of sweating, the exercise was terminated, and they remained seated until the onset of shivering, as reflected in oxygen uptake. In the first two trials, rectal temperature (Tre) was stable, despite displacements in skin temperature (Tsk), whereas in the third trial, Tsk (measured at four sites) was almost constant (30–32°C), and the thermoregulatory responses were initiated due to changes in Tre alone. The results of the first two trials established the peripheral interthreshold zone, whereas the results of the third trial established the core interthreshold zone. The results demonstrated individual variability in the peripheral and core interthreshold zones, a proportional correlation between both zones (r=0.87), and a relatively higher contribution of adiposity in both zones as compared with those of other non-thermal factors such as height, weight, body surface area, surface area-to mass ratio, and the maximum work load.

2-D software datum named as the 2-D mixed method has been constructed to measure mirror surface profiles. The probe of this method consists of two displacement and two angle sensors. Differential calculation of outputs of these four sensors eliminates pitch, roll and the z-directional translation errors of the scanning stages. An autonomous procedure to estimate and compensate the zero-adjustment error among these four sensors is also proposed. By using this software datum, 2-D profiles of ultra-precision surfaces can be measured absolutely without using any external reference. An experimental probe for realizing the 2-D mixed method has been developed and a mirror surface of 128 mm long and 64 mm wide was measured with the probe. Repeatability of measurements and reproducibility compared with the differential angle method have shown high reliability of the proposed method

We proposed a method for a computer-aided diagnosis system that distinguishes between benign and malignant lesions in gastrointestinal digital radiography. To begin with, the level set method was applied in order to extract a tumor region from the image which was smoothed by the bilateral filter. Next, we selected four image features with the large SN ratio among various image features obtained from a tumor region using the Mahalanobis-Taguchi method, which has been employed mainly in quality engineering. The selected four image features—circularity, irregularity, size, and perimeter—were used as input data for the artificial neural network, which was employed for distinction between benign and malignant lesions. By using 43 regions of interest cropped from the 43 clinical cases, the area under the ROC curve (AUC) of diagnostic accuracy for the classification obtained with this proposed method was 0.970, whereas the average AUC obtained with 7 human observers (3 radiologists and 4 radiological technologist) was 0.941.

The local area distribution and relocation of radioactive cesium deposited in trees after the 2011 tsunami-related accident at the Fukushima Daiichi Nuclear Power Plant (FDNPP) have been studied by measuring the spatial distribution of cesium on/in trees by autoradiography analysis. Samples of trees were collected from places located between 4 and 55 km from FDNPP approximately 2, 8, 20, and 22 months after the accident. The autoradiography analyses of Cryptomeria japonica, Torreya nucifera, and Thujopsis dolabrata var. hondae samples collected approximately 2 and 8 months after the accident showed that radioactive Cs was mainly distributed as spots on the branches and leaves of the trees emerged before the accident, and was detected in negligible amounts in new branch and leaves that emerged after the accident. On the contrary, radioactive Cs was detected at the outermost tip of the branches in the trees collected 20 months after the accident. Morus alba samples collected 22 months after the accident contained radioactive Cs inside and outside their stems, even though no radioactive Cs was detected in their roots, strongly suggesting that a certain amount of radioactive Cs was translocated from the outside to the inside of stems. These results indicate that the distribution of radioactive Cs deposited on/in the trees gradually changes with time (scale: year).

Although previous studies have examined what kind of object arrangement could give observer beautiful impression, they have not achieved agreement. While some studies found observers' preference for the arrangements whose centroids were congruent with the center of the picture frame, the other studies found the observers' preference for the arrangement whose centroids were in the right side in the frame. The main purpose of this study is to solve this disagreement among previous studies. We conducted three experiments in which concreteness of the picture was manipulated, and observers rated their impression for the pictures with different centroid position. We used black circles (Experiment 1), concrete objects on white background (Experiment 2), and concrete objects on backgrounds of natural scenes (Experiment 3). Only in Experiment 3, we found that observers consistently preferred for the pictures whose centroid of the arrangement was in right side. Our results indicate that concreteness of the pictures caused the biased preferencefor the right side of the pictures.

Objective We attempted to elucidate the clinical features of chronic hepatitis C patients who develop hepatocellular carcinoma (HCC) after achieving a sustained viral response (SVR) to interferon (IFN) therapy. Methods The clinical features of 130 patients at 19 hospitals who developed HCC after obtaining an SVR were retrospectively reviewed. Results Overall, 107 (82%) of the 130 patients were men, with 92 (71%) being ≥60 years of age and 76, 38 and 16 developing HCC within 5, 5-10 and 10-16.9 years after IFN therapy, respectively. Before receiving IFN therapy, 92 (71%) patients had cirrhosis and/or a low platelet count (<15×104 cells/μL). Lower albumin (<3.9 g/dL) and higher alpha fetoprotein (AFP) (≥10 ng/mL) levels were identified in a multivariate analysis to be independent variables of the development of HCC within five years after IFN therapy. Among 4,542 SVR patients, HCC occurred in 109 (2.4%) during a 5.5-year follow-up period, thus resulting in an occurrence rate of 4.6% for men and 0.6% for women. Conclusion SVR patients with lower albumin or higher AFP levels require careful assessments to prevent early HCC development after IFN therapy. HCC occurrence within >10 years of IFN therapy is not uncommon, and the risk factors remain uncertain, thus suggesting that all SVR patients should undergo long-term follow-up examinations for HCC development.

Dinuclear Co and Fe complexes with a double-decker structure supported by macrocyclic ligands having two bis(imino)pyridine and xanthene groups were synthesized. The dinuclear Fe complex catalyzes ethylene oligomerization in the presence of MMAO or Me3Al to give oligoethylene with ethyl and/or propyl branches due to cooperative interaction of two Fe centers.

1960年代から70年代にかけ、国家レベルの保守政治に対して革新自治体が行なった政策は、「自治」「市民」という言葉の問い直しに基づくものであった。それは「市民」を政治的に活動する存在として考え、「自治」を市民の参加としてとらえるものであった。これをリードしたのが、政治学者の松下圭一であり、彼はその一環として「文化行政」を構想した。本稿は、松下の考えを検証し、「革新」という考えが「文化」に与えた影響を考察する。

The purpose of structural health monitoring (SHM) is to lead a structure to be safer at a lower cost. In SHM, it is important to evaluate the actual state of the structure. Recently, fiber-optic sensors have been developed actively, and one can measure nearly all of the physical measurands of interest by them. Since they also have excellent characteristics such as high sensitivity, immunity from electromagnetic interference, good mechanical characteristics and distributed configuration, they have been applied to “smart structures.” Capability of quasi or fully distributed sensing is especially the significant advantage compared to conventional sensors. We have applied the fiberoptic distributed sensors to SHM in the field and we developed the integrated systems with the fiberoptic sensors and CAD/CAE for two large composite structures. These systems could give us useful information on the structural state, such as deformation and temperature during/after manufacture.

In the 21st Century, it has been announced that several earthquakes will occur beneath Tokyo Capital Region. The Tokyo Metropolitan Government implements two kinds of hazard assessments for countermeasures against the earthquake disasters. One is the disaster damage estimation for Tokyo and a disaster scenario for Earthquake that occurres just beneath Cental Tokyo. According to the Report published in 1997, approximately 378, 000 buildings will be burnt down, 43, 000 buildings will be demolished, 7, 200 people will be killed. A disturbance of the water supply will continue for one month and the interruption of piped gas will continue for two months, more than two million people will be evacuated to shelters located mainly in public schools. The other assessment concerns research on the vulnerability of built-up areas against earthquakes measured according to each community area. According to the area vulnerability research, the most vulnerable areas are located as a ring-zone around the CBD and as a finger-zone along Japan Railway's Chuo-line from central Tokyo to the west suburban region (Pictorial 4-1). These zones are made up wooden houses in crowded areas without city planning nor building permission.TMG learned much from the Kobe Earthquake of 1995 and has enlarged earthquake countermeasures to make Tokyo an earthquake-resistant city and to secure effective disaster countermeasures, quick recovery and reconstruction to protest the livelihood of the populace, and to ensure urban redevelopment. The most important measure is the Promotion Plan for Earthquake-resistant City Development Projects, because the implementation of such projects can reduce the damage in Tokyo (Pictorial 4-2). The Preparedness Plan for Urban Reconstruction is one of the new measures that was established after the Kobe Earthquake.

Feline leukemia virus (FeLV) induces neoplastic and non-neoplastic diseases in cats. The transduction of cellular genes by FeLV is sometimes observed and associated with neoplastic diseases including lymphoma and sarcoma. Here, we report the first natural case of feline Notch2 transduction by FeLV in an infected cat with multicentric lymphoma and hypercalcemia. We cloned recombinant FeLVs harboring Notch2 in the env gene. Notch2 was able to activate expression of reporter gene, similar to what was previously reported in cats with experimental FeLV-induced thymic lymphoma. Our findings suggest that the transduction of Notch2 strongly correlates with FeLV-induced lymphoma.
