A patient with untreated Wilson's disease showed the possibility of fetal liver damage and copper accumulation in the placenta by this disease. This is the first report of copper disposition on the fetus and placenta in a patient with untreated Wilson's disease. 相似文献

A new transmission scheme for channels with intersymbol interference named "matched-transmission (MT) technique" is proposed. An implementation of the MT system is presented and its relations with conventional techniques are described. It is shown that the partial response scheme is a special case of our new technique. The performance of the MT technique is discussed from the view point of the output signal-to-noise ratio and the system is shown to attain asymptotically the bound performance predicted by the information theory. 相似文献

The OSE Project aims at developing the technology to utilize solar energy for heating, cooling and hot water supply on the basis of various technology for energy conservation in buildings. For the first step of this project a solar heating and cooling system with flat plate collectors and absorption refrigeration machine was installed in a house in 1974. This paper reports outlines of the system and operating results. 相似文献

The nature of the magnetic interactions in RuF5 and OsF5 has been investigated using neutron diffraction and magnetic measurements under high applied fields. RuF5 and OsF5 are magnetically ordered at respectively TN = 5 and 6 K. The magnetic structures have been determined. A model based on isolated tetranuclear clusters M4F20 (M = Ru or Os) has been applied to explain the magnetic behavior above the Néel temperature. The intracluster exchange interactions are antiferromagnetic. The fitting of the magnetization data leads to an exchange constant of for RuF5, in good agreement with that calculated from the thermal variation of the magnetic susceptibility. 相似文献

We report on our prototype experiment that uses a 4-m detuned resonant sideband extraction interferometer with suspended mirrors, which has almost the same configuration as the next-generation, gravitational-wave detectors. We have developed a new control scheme and have succeeded in the operation of such an interferometer with suspended mirrors for the first time ever as far as we know. We believe that this is the first such instrument that can see the radiation pressure signal enhancement, which can improve the sensitivity of next-generation gravitational-wave detectors. 相似文献

Concerning a role of blood rheology for atherosclerosis in patients with hemodialysis (HD), little data are available. It may be due to the fact that the method for evaluating rheologic properties of circulating blood has been limited. We examined blood rheology in 118 HD patients by using microchannel array flow analyzer that makes it possible to directly observe the flow of blood cell elements through the microchannel. Transit time (T(B)) of heparinized whole blood through slit pores (7 x 30 microm) was used as an index of rheology and related with various inflammatory biomarkers such as high-sensitive CRP (hsCRP), monocyte chemotactic protein-1, osteopontin, or fibrinogen (Fg). Moreover, as a surrogate marker of atherosclerosis, carotid intima-media thickness (IMT) and aortic stiffness evaluated by brachial-ankle pulse-wave velocity (baPWV) were studied. In HD patients, T(B) had strong positive correlations with hsCRP (r = 0.427; p < 0.00001), Fg (r = 0.452; p < 0.00001), and osteopontin (r = 0.227; p < 0.0134). Further, T(B) was significantly well correlated with IMT (r = 0.400; p < 0.0001) and PWV (r = 0.470; p < 0.0001). Multivariate regression analysis showed that baPWV, IMT, Fg, hematocrit, white blood cell count, and CRP were chosen as significant explanatory factors for T(B.) These results suggest that blood rheology may play an important role for atherosclerosis in patients with HD. 相似文献

M. M. a man aged 49. He suffered from a head injury at the aged of 41. At that time he lost consciousness for a few minutes and he was diagnosed as a consquassatio cerebri. The sequelaes of his head injury were a change of character and a disturbance of autonomic nerve function. The changes of character were decreased of activity, lie-down for all day, decrease of speech and depressive mode, and occasionally he was ill-humored, restless and irritative. Periodically he became euphoris, talkative and childisch. He had a disturbance of autonomic nerve function which became worse in parallel to the depressive states. We speculated that character changes, such as manic-depressive states and disturbances of autonomic nerve function were due to the bruising of the bilateral orbital surfaces of frontal lobes. 相似文献

A high‐performance ambipolar light‐emitting transistor (LET) that has high hole and electron mobilities and excellent luminescence characteristics is described. By using this device, a conspicuous light‐confined edge emission and current‐density‐dependent spectral evolution are observed. These findings will result in broader utilization of device potential and they provide a promising route for realizing electrically driven organic lasers. 相似文献

This paper reports the development of membrane sensors based on an artificial lipid and plasticizers with high selectivity and sensitivity to drug bitterness by using bis(1-butylpentyl) adipate (BBPA), bis(2-ethylhexyl) sebacate (BEHS), phosphoric acid tris(2-ethylhexyl) ester (PTEH), and tributyl o-acetylcitrate (TBAC) as a plasticizer and phosphoric acid di-n-decyl ester (PADE) as an artificial lipid to optimize surface hydrophobicity of the sensors. In addition, a sensor with highly correlated bitterness sensory score was developed by blending BBPA and TBAC to detect the bitterness suppression effect of sucrose, and other bitter-masking materials. Therefore, this sensor can be used to evaluate the bitterness of various drug formulations with high accuracy. Copyright © 2009 Institute of Electrical Engineers of Japan.

Ant colony optimization (ACO) is based on the behavior of food gathering of ants and it is a powerful search tool particularly when applying it to combinatorial optimization problems. However, ACO has the inherent problem of substantial processing time, because it requires a lot of repetitive calculations. In this article, we propose novel hardware‐oriented ACO (H‐ACO) to reduce processing time. H‐ACO adopts new integer arithmetic instead of conventional floating point arithmetic in the optimization process and it achieves high‐speed processing while keeping the quality of solutions. In addition, H‐ACO reduces the hardware resources, accelerates the clock frequency, and improves the latency, if it is implemented as a dedicated hardware. Furthermore, we also propose a new route guidance algorithm which combines H‐ACO with Dijkstra's algorithm and it can be applied to a dynamic route guidance problem. Experiments using actual map data demonstrate the validity of the proposed route guidance algorithm. © 2011 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc. 相似文献
