ISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: Cubic-boron nitride (c-BN) thin films were grown by dual ion beam sputter deposition and the growth mechanism was studied using angle resolved in-situ XPS (x-ray photoelectron spectroscopy) analysis. The π bond shake-up satellite of the B 1s peak, which is observed only in a hexagonal boron nitride (h-BN) phase, appeared in the XPS spectrum obtained for the surface layer of the c-BN film. This can be a clear evidence that the c-BN phase grows via the transformation of an initially formed h-BN phase and the transformation is induced by the compressive stress accumulated in the subsurface region during ion bombardment. © 1997 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1999Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: A dual-gate-controlled single-electron transistor with coupled dot geometry has been fabricated on a silicon-on-insulator structure. Coupled dots are defined by tunable gates which are designed to separately control the tunneling potential barriers to compensate for disorder due to size fluctuation in quantum dots. The Coulomb-blockade phenomena observed in linear and nonlinear transport regimes were found to be enhanced by the multidot coupling. The Coulomb staircase (nonlinear effect) appears more clearly with the increasing number of coupled dots, indicating definite suppression of the inevitable cotunneling process. In the linear regime, the frequency of Coulomb oscillation was able to be tuned by changing the interdot coupling strength. These results indicate that enhancement of the Coulomb blockade and tunability can be achieved through replacing the traditional single dot by gate-controlled multidots in future single-electron devices. © 1999 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 2000Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: We report low-temperature conductance measurement on a Coulomb-blockaded dot in a silicon-on-insulator-based single-electron transistor with in-plane side gates. The linear conductance for 4.2 K at zero magnetic field exhibits up to three paired peaks, indicating simple alternating odd (spin 1/2)-even(spin 0) filling. Three intrapair spacings are found to be nearly a constant value, corresponding to the single charging energy U, whereas two interpair spacings are different which are associated with U+ΔE1 and U+ΔE2, i.e., successive quantized level spacings added to U. The quantized level spacings were also revealed in the nonlinear current staircases. © 2000 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

High-resolution transmission electron microscopy revealed that these nanowires are single nanocrystals, and energy dispersive x-ray indicated that these nanomaterials are free of any metals. In addition, bundles of these crystalline nanowires in the rectangular-pole shape are a few centimeters in length.© 2002 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 2004Staff ViewISSN: 1365-2222Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Objectives The International Study of Asthma and Allergies in Childhood (ISAAC) questionnaires have shown that the prevalence of childhood asthma is increasing worldwide. Although Asian countries used to have lower prevalence rates of allergic disease than Western countries, this prevalence is increasing in several Asian countries. To determine whether the prevalence of childhood asthma is changing in Korean adolescents, we compared findings from nationwide cross-sectional surveys in 1995 and 2000 on populations of middle-school children using the Korean version of the ISAAC questionnaire.Methods We developed Korean versions of the ISAAC written (WQ) and video (AVQ) questionnaires for allergic diseases. In 1995, the enrolled population consisted of 15 481 children, ages 12–15, and encompassing all three grades in middle school, selected from 34 schools across the nation; the response rate was 97.3%. In 2000, 15 894 children were selected from 31 of the same schools, and the response rate was 96.4%. The SAS system version 8.0 was utilized for all statistical analyses.Results The WQ showed that the lifetime and 12-month prevalence of wheeze did not change from 1995 to 2000. While the 12-month prevalence rates of sleep disturbed by wheezing and night cough increased, the rates of severe attack of wheezing and exercise-induced wheeze did not change, over this period of time. The lifetime prevalence of asthma diagnosis, however, increased significantly, from 2.7% in 1995 to 5.3% in 2000, as did the 12-month prevalence of asthma treatment, from 1.0% in 1995 to 1.9% in 2000. The AVQ also showed increases in the lifetime and 12-month prevalence rates of wheeze at rest, exercise-induced wheeze, nocturnal wheeze, nocturnal cough, and severe wheeze over this period of time. These were especially because of significant increases in the Provincial cities of Korea. Interestingly, the 12-month prevalence of wheeze was consistently high in Cheju with low air pollution indices, whereas this rate was low in Ulsan and Ansan with very high air pollution indices. Risk factor analysis showed that body mass index (BMI), passive smoking, and living with a dog or cat, but not air pollution, were associated with higher risk of wheeze.Conclusions In the 5-year period from 1995 to 2000, the prevalence of asthma symptoms has increased in Korean adolescents, much of it because of increases in Provincial Centers. BMI, passive smoking, and living with a dog or cat are important risk factors. Environmental factors other than air pollution may be associated with increases in asthma, especially in Provincial Centers.Type of Medium: Electronic ResourceURL: -

ISSN: 1572-817XSource: Springer Online Journal Archives 1860-2000Topics: Electrical Engineering, Measurement and Control TechnologyPhysicsNotes: Abstract A study of numerical modelling has been carried out for chemical vapour deposition processes with applications to manufacture of optical fibres. Temperature distributions and thermophoretic particle deposition have been calculated for the modified chemical vapour deposition (MCVD) and the outside vapour deposition (OVD) processes. A two torch formulation and a heat flux boundary condition are used for MCVD and the present model is shown to be capable of predicting tube wall temperatures and deposition profiles correctly. The present results are in agreement with experimental data. For OVD modelling, nonorthogonal body-fitted coordinates have been utilized to solve a conjugate problem including the jet flow and heat conduction through a two-layered cylinder that consists of an original target and the deposited porous layers. Surface temperatures and efficiencies of particle deposition have been obtained.Type of Medium: Electronic ResourceURL: -

Published 1987Staff ViewISSN: 1432-1203Source: Springer Online Journal Archives 1860-2000Topics: BiologyMedicineNotes: Summary Six individuals with complete deficiency of erythrocyte AMP deaminase have been discovered. They are all healthy and have no hematological disorders. The deficiency is only in isozyme E, which is the erythrocyte type isozyme, and is inherited as an autosomal recessive trait. The frequency of the mutant gene is surprisingly high, one heterozygote in about 30 of the population in Japan, Seoul, and Taipei. The ATP level is approximately 50% higher in AMP-deficient erythrocytes compared to that of control cells. Degradation of adenine nucleotide is slower in the deficient erythrocytes than in the control erythrocytes.Type of Medium: Electronic ResourceURL: -

ISSN: 1741-0444Keywords: Correlation ; Visual evoked potential ; Visual pathway ; Weighting matrixSource: Springer Online Journal Archives 1860-2000Topics: BiologyChemistry and PharmacologyMedicineNotes: Abstract Visual evoked potentials (VEPs) were measured using 19 electrodes attached to the scalps of five normal human subjects during stimulations of the full-field and hemifield chequerboard pattern reversal. These signals were analysed by a new method based on the time locus of the potential distribution centre, where this locus was computed from the spatial potential distribution using the weighting matrix and maximum mean cross-correlation criteria. The results showed that the loci of normal subjects are similar, with an average correlation of 0·87. The loci produced in the left hemifield stimulation were different from the loci produced during the right hemifield stimulation, with a correlation of −0·66. Experimental results from four cats showed significant changes of the time loci after surgical division of the visual path-ways.Type of Medium: Electronic ResourceURL: -

ISSN: 1435-232XSource: Springer Online Journal Archives 1860-2000Topics: BiologyMedicineNotes: Summary Urine amylase activity was measured in 142 boys and girls including unrelated twin individuals, aged 12–16 years. Statistical analysis revealed different distribution in the group with positive protein or blood reaction. Log distribution in a homogeneous sample population was unimodal with a skewness ( $$\sqrt {\beta _1 } $$ =−0.6493) and kurtosis (β2=3.4917). Intraclass correlation coefficients of overall activities were 0.6696 (p〈0.001) in MZ twins (50 pairs) and −0.1299(n.s.) in DZ twins (22 pairs). In the rate of isozyme activity, correlation was nonsignificant. Plasma of 36 twin pairs aged 13 to 15 years were similarly examined. Log distribution of overall activity was unimodal with a skewness ( $$\sqrt {\beta _1 } $$ =0.2321) and kurtosis (β2=0.7416). Intraclass correlation coefficients of overall activity were 0.8413 (p〈0.001) in MZ twins (29 pairs) and 0.3689 (n.s.) in DZ twins (7 pairs). Intraclass correlation of plasma isozyme activity rate was 0.5490 (p〈0.01) in MZ twins, but not significant in DZ twins. Parent-offspring correlation of plasma overall amylase activity was 0.2848 (p〈0.05) and its mid-parent-offspring correlation was 0.3727 (p〈0.05). Heritability was 0.5298 from parent-offspring regression and 0.4408 from mid-parent-offspring regression.Type of Medium: Electronic ResourceURL: -

Twenty elements of Au, Br, As, W, Cr, Co, Na, Eu, La, Se, Zn, U, Th, Hf, Fe, Sb, Ag, Ce, Tb and Ta have been analyzed in p- and n-type wafers, single crystals and a polycrystal by a single comparator method using two comparators of gold and cobalt. Considerable surface contamination has been found and could be removed by etching the surface with nitric and hydrofluoric acid before and after irradiation. The impurity concentration has been found to be generally increased in the process of single crystal growth. The vertical and radial distributions of impurities have revealed that some impurity elements were more concentrated in the top region of a single crystal rod than in the middle region, and that Br, Cr, La, Eu and Sb were enriched in the central region and As, U and Fe in the outer region.Type of Medium: Electronic ResourceURL: -
