Characteristics of transmission lines fabricated by CMOS process with deep n-well implantation

IEEE TRANSACTIONS ON MICROWAVE THEORY AND TECHNIQUES 2006年第2期54卷 589-598页

作者： Nishikawa, K Shintani, K Yamakawa, S Advanced Technology Research and Development Center Mitsubishi Electric Corporation Limited Hyogo Japan

We characterized the properties of transmission lines fabricated using a CMOS process with a deep n-well implantation and compared them with the properties of the transmission lines on the silicon substrate with other well formations, e.g., a p-well and those Without well formations. The series inductance of the transmission line is nearly constant, for both the various well formations and the resistivities of the silicon substrate. The characteristic impedance of the transmission line on the silicon substrate with the deep n-well is higher than this value on the substrates with the p-well and those without well formations. This is because the capacitance of the transmission line on the silicon substrate with the deep n-well is larger due to the p-n junction. Moreover, the capacitance of the transmission line on the substrate with the deep n-well decreases when the dc bias voltage applied to the deep n-well is increased. The capacitance of the transmission line on the substrate with the deep n-well is nearly constant for the various resistivities of the silicon substrate, while the capacitance of the line on the substrate with the p-well decreases with higher resistivity of the substrate.

PLANT GROWTH REGULATION 2002年第3期38卷 225-230页

The effects of light generated by monochromic blue, red or mixed radiation from a fluorescent lamp (FL) with light emitting diodes (LEDs) (blue, red, or far-red) on growth and morphogenesis of marigold and salvia seedlings were investigated and the responses compared with those of plantlets grown under a broad spectrum conventional fluorescent lamp (a 16 h photoperiod per day). Dry weight of marigold seedlings was significantly increased in monochromic red light (R), fluorescent light plus red LED (FLR) or fluorescent light (FL) but reduced when monochromic blue light (B) was used, whereas in salvia dry weight was significantly greater under fluorescent light plus blue LED (FLB), fluorescent light plus red LED (FLR) and fluorescent light plus far-red LED (FLFr) as compared to other treatments. Stem length in marigold was greatest in monochromic blue light, being three times greater than in FLR or FL treatments. In salvia, FLFr increased stem length but this was significantly decreased by R as compared to other treatments. The number of visible flower buds in marigold was much higher in FLR as well as in the control (FL), and it was about five times greater than in B or R. However, the number of open flowers in salvia varied slightly in all the treatments. Different light qualities also influenced the duration of the blooming period in both the species. No flower buds were formed when monochromic B or R was used in salvia and FLFr inhibited flower bud formation in marigold. In comparison with monochromic blue or red light, the number of stomata was greater in mixed radiation of FL with LEDs in both the plants. Our study demonstrates the effectiveness of a LED system for plantlet growth and morphogenesis in space-based plant research chambers.

This study presents novel magnetic core designs, magnetically anisotropic plain or tiled types, for planar spiral inductors that can effectively use magnetic anisotropy in the place of nano-granular [CoFeB-SiO2/SiO2] laminated magnetic cores. Inductance and resonant frequency for the proposed inductors showed significant enhancement through both finite element method calculation and experimentation. Additionally, the inductor was implemented onto a DC-DC converter successfully to demonstrate the step-down performance and showing corresponding waveforms. The efficiency of DC-DC converter with the inductor exhibited higher values under light load conditions. This comprehensive demonstration highlights the potential of our innovative design for advancing the field of integrated magnetics and developing more efficient power electronic devices. © 2025 IEEE.

Long-rod impact phenomena: Role of wave interaction on crack propagation

引用

INTERNATIONAL JOURNAL OF IMPACT ENGINEERING 1995年第1-3期17卷 195-204页

作者： Choi, JH Lee, CH Chang, SN Moon, SK Advanced Technology Research Center Agency for Defense Development Taejon S. Korea

Long-rod impact experiments were performed at high velocity (about 1500 m/s) against two different transparent targets: PMMA and glass. Early penetration phenomena of wave and crack propagation have been observed by means of high-speed camera. Microcracks always occur behind the shock wave front. Release waves reflected from the side boundaries of target can result in secondary cracking in front of main fracturing. The wave interaction due to different impedance on the target boundaries affects crack propagation. Thus, size of target and confining materials may play important roles of protection capability against the penetrator.

We report the absorption-coefficient variation of a tensile-strained InGaAs/InP quantum well measured throughout the spectral range near and away from the band gap. We discuss the spectral absorption-coefficient variation spectra of an unstrained, a 0.15%, a 0.30% a 0.45% tensile-strained quantum well and show that the difference between the wavelengths of absorption-coefficient variation peak for TE and TM modes becomes zero with 0.3% tensile strain. We will also show that this wavelength difference varies linearly with the magnitude of the strain.

Our previous research identified amino acid nitrogen (AAN) as a key component reflecting umami taste in the fermentation process of sufu. Given microbial metabolism's crucial role in sufu's flavor, this study aimed to explore AAN formation through metagenomic analysis. Results indicate that core species involved both bacteria (e.g., Dysgonomonas macrotermitis, Comamonas, jiangduensis, Enterococcus casseliflavus, Weissella confusa, and Lactococcus lactis) and fungus (e.g., Rhizopus arrhizus, and Mucor lusitanicus). Genes from these core species were linked to enzymes involved in ANN metabolism, particularly abundant in protein hydrolases and amino acid hydrolases. Functional annotation highlights that carbohydrate and amino acid metabolism were the primary pathways contributing to flavor development. Predicted metabolic pathways suggest that Glu formation was associated with pathways ko00220 and ko00250, in addition to the enzymes glutamate synthetase (EC 1.4.1.13) and glutamine synthetase (EC 6.3.1.2). This research advances our knowledge of microbial roles in sufu taste biosynthesis. © 2025, The Authors. All rights reserved.

Relationship between helium isotopes and focal depths of low-frequency earthquake, Northeastern Japan

Low-frequency earthquakes (LFEs) observed around volcanoes are often interpreted as reflecting the boundary of the magma transport channels or magma reservoirs. On the other hand, the occurrence of mantle-derived helium is closely related to current or recent magmatism in subduction zones, owing to mantle melting being the primary mechanism for the transfer of primordial ³He from the mantle to the lithosphere. The elevated ³He/⁴He ratios observed surrounding volcanoes could indicate the presence of a magmatic plumbing system. Therefore, it is meaningful to investigate the relationship between the helium isotope variations and the location of LFEs in volcanic regions. There appears to be good correlation between helium isotope ratios and focal depths of LFEs observed in 31 volcanic regions of Northeast Japan. The helium isotope ratio increases as the focal depth of the low-frequency earthquake decreases. These findings indicate that the shallower the depth of the magma reservoir, the smaller the contamination of primordial helium with crustal radiogenic helium, resulting in higher helium isotopes observed at the surface. Many volcanic hazard factors, such as the probability and duration of an eruption, the eruption style, and the probability of triggering large landslides or caldera collapses, are related to the depth of the magma source. Combining helium isotope monitoring with low-frequency earthquake observations has the potential to improve the reliability of future eruption prediction. © The Author(s) 2025.

An innovative Galerkin scheme based on anisotropic trilinear immersed finite elements for the magnetized plasma diffusion problem with plasma sheath interface

Via introducing the Robin flux jump into the Galerkin scheme, this paper develops a new anisotropic trilinear immersed finite element (IFE) method for solving the magnetized plasma diffusion problem with plasma sheath interface condition under Cartesian meshes. The three-dimensional (3D) diffusion process of magnetized plasma is anisotropic and highly sensitive to magnetic fields, making it difficult to efficiently solve by commonly used body fitted mesh methods when the simulation domain has complex boundary conditions. Even worse, the plasma sheath boundary will further exacerbates its solving difficulty. The presented method first utilizes the anisotropic trilinear IFE basis functions describing the diffusion of magnetized plasma in interface elements. Then the trilinear IFE basis functions are used to handle the plasma sheath interface conditions, i.e. the Robin flux jump conditions. As for the other non interface elements, the traditional trilinear basis functions are used. On this basis, a new Galerkin scheme is derived and applied to efficiently solving the plasma anisotropic diffusion problem with the Robin flux jump interfaces in Cartesian meshes. The proposed method can also solve other types of elliptical interface problems via controlling the coefficients. Moreover, the orthogonal meshes makes it convenient to couple other Cartesian mesh based methods, such as the particle-in-cell method, which provides an advanced tool for solving plasma transport problems. Numerical experiments are provided to demonstrate the proposed method and show the applicability in the simulations of actual engineering issues.
