A technique to synthesize a 3-D Kabuki face model from ancient images is proposed. Kabuki is a traditional Japanese theater art. Kabuki researchers can know some ancient information of Kabuki from the ancient 2-D images such as Ukiyo-e (Japanese drawing) and Kumadori images (Kabuki makeup). Compared with the real face images in photographs and paintings, the face images in Ukiyo-e and Kumadori images were distorted a little from the real face for art representation. Hence, it is necessary to synthesize a new 3-D face model between the 3-D real face original model and the 2-D images. A deformation technique is proposed for transforming 3-D real face original models according to the 2-D images, and a mapping algorithm is given to map the images onto the 3-D face shape model. To ensure balance between precision and smoothing of 3-D model deformations and mappings, the radial basis function (RBF) is developed and a multilevel RBF is proposed. This multilevel RBF solver can be used to deform the 3-D real face model as well as map the 2-D images onto the 3-D face model. Some experimental results are given to demonstrate the effect of this technique.

All available magnetic data from observatories, satellites, repeat station measurements, and aeromagnetic, shipborne and land surveys are used to derive spherical harmonic models of the geomagnetic field from 1970 to 1990. Two models are derived, one using data from the DE-2 satellite the other not, since the quality of that data is unknown. These models are designated GSFC (11/90) D and GSFC (11/90) respectively. Main field coefficients are determined up to degree 13 and temporal variation, represented by B-splines, up to degree 10. Bias values at the fixed observatories were included as part of the solution. The secular variation models are smoothed by use of norm minimization. Both models fit the data very well.The resulting secular variation shows a jerk-like trend change in several coefficients near 1979.Candidate DGRF 1985 and IGRF 1990 models are extracted from the more general models by projecting to the desired epoch and using a truncated version of the main field spherical harmonic coefficients at those epochs.

Class II alcohol dehydrogenase (π-ADH), encoded by alcohol dehydrogenase (ADH4), is considered to contribute to ethanol (EtOH) oxidation in the liver at high concentration. Four single nucleotide polymorphisms (SNPs) were found in the promoter region of this gene. Analysis of genotype distribution in 102 unrelated Japanese subjects revealed that four loci were in strong linkage disequilibrium and could be classified into three haplotypes. The effects of these polymorphisms on transcriptional activity were investigated in HepG2 cells. Transcriptional activity was significantly higher in cells with the -136A allele than in those with the -136C allele. To investigate whether this difference in transcriptional activity caused a difference in EtOH elimination, previous data on blood EtOH changes after 0.4 g/kg body weight alcohol ingestion were analyzed. When analyzed based on aldehyde dehydrogenase-2 gene (ALDH2) 487Glu/Lys genotype, the significantly lower level of EtOH at peak in subjects with -136C/A and -136A/A genotype compared with subjects with -136C/C genotype indicated that -136 bp was a suggestive locus for differences in EtOH oxidation. This effect was observed only in subjects with ALDH2 487Glu/Glu. These results suggested that the SNP at -136bp in the ADH4 promoter had an effect on transcriptional regulation, and that the higher activity of the -136A allele compared with the -136C allele caused a lower level of blood EtOH after alcohol ingestion; that is, individuals with the -136A allele may consume more EtOH and might have a higher risk for development of alcohol dependence than those without the -136A allele.

An experimental proof-of-principle of an enhanced Z3DT (thermoelectric figure of merit) is demonstrated using (001) oriented Si/Ge superlattices. The highest value of the experimental Z3DT at 300 K for a (001) oriented Si(20 Å)/Ge(20 Å) superlattice is 0.1 using κ = 5 Wm−1 K−1, for the in-plane thermal conductivity, which is a factor of seven enhancement relative to the estimated value of Z3DT = 0.014 for bulk Si. The good agreement between experiment and theory validates our modeling approach (denoted as “carrier pocket engineering”) to design superlattices with enhanced values of Z3DT. Proposals are made to enhance the experimental values of Z3DT for Si/Ge superlattices even further. © 2000 American Institute of Physics.

In this paper, we propose the criteria of bias voltage from parasitic capacitance and demonstrate the criteria in an experiment with the present IGBT. The bias voltage criteria are theoretically predicted for the new generation IGBT based on the scaling principle. For safe switching, the required gate voltage bias is predicted to be −1.2V or less for the present IGBTs and −6V or less is required to completely cancel the gate noise voltage. From the IGBT design, the bias voltage of scaling IGBT requires −2V to completely cancel the gate noise voltage.

Combustion synthesis technology can be advantageously applied to high-temperature experiments under microgravity environments(MOE) not only as a direct synthesizing method for high-temperature materials but also as a super-heating chemical oven, because it is possi­ble to get high temperatures more rapidly compared to conventional electric furnaces. In the present work, the combustion synthesis of ZrO2-A}zO3-Fe and TiB2-Al-B composite systems have been carried out using a TR-IA sounding rocket which provides about 10- 4 g0 for six minutes. As the former result, more uniform distribution and finer particles of ZrO2 could be attained under MOE, which would be caused from no disturbance in mass migration. As the latter, the composite layered particles composed of TiB2 and Al-B system synthesized under MOE were more uniform compared to those obtained on earth, which would result in the formation of denser cermet-like products.

バナナつぼみ中のポリフェノール成分は主要成分としてフラバナンタンニン(縮合型タンニン),副次成分としてカテキン,そのオリゴマー,ドパミン及びドパから成っていた.数品種のつぼみのうち,調理用バナナである'サバ'品種のつぼみにおいて,フェノール全量やバニリン陽性フェノール量は最も少なかった.ポリフェノールオキシダーゼ(PPO)活性の品種間差異は著しくはないが,つぼみ中の部位による差は顕著であり,又その活性は果実の場合よりもかなり大きかった.つぼみのPPO活性は, 0.13M食塩で約20%抑制された.なおフィリピンにおいて,'サバ'品種つぼみを加熱・調理する際に,その薄片に約10%(1kg当り約1.71M)の食塩を加え,汁液をしぼりとるが,これは食塩によりPPO活性を抑制して加熱後の色を鮮やかな淡赤色にするためであり,他には食塩添加により膨圧を失わせ,渋味・苦味の原因となるポリフェノ―ルを除くためであることが分かった.他の品種の場合には,食塩添加,搾汁,加熱によっても渋味・苦味は十分に除去されなかった.
