In order to collect biological data of human in real-time, we developed biological data collection system (BDCS) using a cellular phone. The BDCS consists of EMA system and biological measuring devices (BMD) system. In this study, the EMA system was implemented to obtain subject behaviors and feelings related sleep around two weeks and BMD to obtain biological data such as snoring, skin impedance,...
In this report, we introduce a new physiological model of the serum creatine phosphokinase (CPK) activity change, that is useful for estimating the total CPK release accurately even with reduced blood sampling frequency. The physiological model was applied to the serum CPK activity change of patients who suffered acute myocardial infarction (AMI), and the model showed good agreement with the serum...
Nonlinear optical response of cavity polaritons formed in high-g semiconductor microcavities has attracted much attention because of their potential applications to entangled-photon sources and other quantum information technologies. Theoretical ideas of entangled-photon generation, e.g., biexcitonic cavity quantum electrodynamics and polariton-polariton scattering, have been suggested, however these...
A half of melanomas in non-white populations are from acral volar area and an appearance of these lesions is completely different from that of other parts of lesions. However, no research for classifying these lesions has been conducted. In this paper, we describe a diagnosis classifier of acral volar melanomas. We used our dermatologist-like tumor area extraction algorithm and extracted a total of...
Improvement of DC-DC converter side in SMPS system is discussed in this paper. A novel forward type soft switching DC-DC converter topology with neutral point inductor connected auxiliary resonant snubber (NPC-ARS) circuit is presented in this paper for the switching mode power supply applications. Its circuit operation and its performance characteristics of the forward type soft switching DC-DC converter...
In this paper, we develop an automated method to recognize the dermoscopic criteria used for diagnosing melanomas as defined by two commonly used diagnostic schemes, namely the ABCD rule and the 7-point checklist. We use a database of 105 dermoscopy images and their dermoscopic findings determined by four dermatologists as the gold standard. We extract 356 objective image parameters from the images...
The development of new photoinitiators which provide additional value to the curing efficiency is reported. These include compounds with low migration and volatility properties avoiding the leaking of chemicals into the environment, initiators that provide a high photosensitivity to black formulations and novel photolatent bases which allow the curing of formulation hitherto not available for radiation...
Summary A 60-year-old woman presented with a subcutaneous mass on her scalp. Computed tomography (CT) showed a homogeneously enhanced mass of the parietal bone with both intra- and extra-calvarial extension and having destroyed the right parietal bone. The mass was hypointense on the T1-weighted magnetic resonance image, slightly hyperintense on the T2-weighted image and homogenously enhanced with...
Administration of clinical photographs taken by commonly used digital camera often requires troublesome manual operation. In this paper, we made a prototype scheme of automatic photographed area identification from clinical images to help or reduce administration task. A total of 8047 clinical photographs taken in department of dermatology, Keio University Hospital, were classified into 11 categories;...
We studied the atomistic structure of boron atom at the Si(001)/SiO2 interface using ab initio calculation method to investigate the mechanism of boron pile-up at the interface. We found that, if there is no defects, such as oxygen vacancy, at the interface, no stable sites of B would appear at Si/SiO2 interface and SiO2 layer, thus indicating that boron in silicon will only diffuse to the interface,...
Nonuniformity at the gate oxide interface is considered to be one of the serious fluctuation issues, which is induced by polysilicon grain boundary, impurity segregation, silicide and high-k stack. We introduce a mosaic layer at the gate oxide interface and relate the degree of the nonuniformity with device characteristics through multifractal analysis. There is an analogy between the degree of randomness...
As CMOS technology is dramatically scaled down in recent years, the operation of SRAM becomes one of critical issues for further scaling. In this paper, we have focused on both FD SGSOI and DG (FinFET) devices because of the scaling capabilities, and we have simulated SRAM SNM with discrete dopant fluctuations in the channel regions by 3D simulation. As for SNM, FinFET is a promising candidate up...
Fluorine related diffusion has drawn extensive attention recently, for experiments revealed that co-implanted F in Si can reduce transient enhanced diffusion (TED) of boron. However, disagreement still exists on whether this effect is caused by interaction of F with point defects or that with boron atoms. Also, some unusual F diffusion behaviors are still not thoroughly understood. We attempt to establish...
A molecular dynamic method for cluster implantation simulation which is a potential technology for shallow junction formation in integrated circuits manufacture, aimed at microelectronics application, is presented in this paper. Accurate geometric structures of boron clusters including H atoms are described by the model. A potential function taking a form of combining the ZBL and the SW potentials...
The kinetic Monte Carlo (KMC) method has been the applicable method for the investigation on annealing process. In this paper, the simulation on both enhanced diffusion and inactivation of B is presented. The inactivation and clustering of B implanted at 0.5 keV and annealed at 900degC~1200degC are correctly simulated. The model can also correctly simulate the enhanced diffusion of B introduced by...
