Semiconductor module comprising semiconductor packages

Abstract: Each of two semiconductor elements 1a or 1b is connected to wiring patterns 3a or 3b on an element substrate 2a or 2b via a bump 4a or 4b, respectively. These members are sealed off by sealing resin to form a semiconductor package 6a or 6b, and the same are disposed on a mounting substrate 8 one above the other with an adhesive agent 9 applied thereto. A portion of the wiring pattern 3a not covered by the sealing resin 5, which portion is connected to the semiconductor element 1a, a portion of the wiring pattern 3b connected to the semiconductor element 1b, and an electrode on the mounting substrate 8 are electrically interconnected by connecting wires 7.

Decomposition of LiPF6and Stability of PF 5 in Li-Ion Battery Electrolytes Density Functional Theory and Molecular Dynamics Studies

Abstract: The decomposition of and the stability of in organic solvents, diethyl carbonate (DEC), dimethyl carbonate (DMC), γ-butyrolactone (GBL), and ethylene carbonate (EC), have been investigated through density functional theory (DFT) calculations, in which solvent was modeled as a dielectric continuum, and also by molecular dynamics (MD) simulations which treated solvents explicitly. Both calculations showed a similar trend in which the decomposition was further promoted in more polar solvents, yet the DFT calculations predicted an endothermic decomposition, while the MD simulations indicated exothermic. This sharp contrast in the results suggests strong solute-solvent interactions, especially for which were not accounted for in the DFT calculations. The specific interaction between and solvent was further investigated by DFT calculations for adduct models and also by the MD simulations for solutions. Both calculations suggest a stable formation of a -solvent adduct in solution and its stability depends on the solvent. It was found that is more stabilized in polar and sterically compact solvents such as EC and GBL than in less polar and bulky, linear carbonates such as DMC and DEC. The reactivity of with organic solvents and the difference in the stability of between organic and aqueous solution are also discussed. © 2003 The Electrochemical Society. All rights reserved.

Influenza infection in suckling mice expands an NKT cell subset that protects against airway hyperreactivity

Abstract: Infection with influenza A virus represents a major public health threat worldwide, particularly in patients with asthma. However, immunity induced by influenza A virus may have beneficial effects, particularly in young children, that might protect against the later development of asthma, as suggested by the hygiene hypothesis. Herein, we show that infection of suckling mice with influenza A virus protected the mice as adults against allergen-induced airway hyperreactivity (AHR), a cardinal feature of asthma. The protective effect was associated with the preferential expansion of CD4–CD8–, but not CD4+, NKT cells and required T-bet and TLR7. Adoptive transfer of this cell population into allergen-sensitized adult mice suppressed the development of allergen-induced AHR, an effect associated with expansion of the allergen-specific forkhead box p3+ (Foxp3+) Treg cell population. Influenza-induced protection was mimicked by treating suckling mice with a glycolipid derived from Helicobacter pylori (a bacterium associated with protection against asthma) that activated NKT cells in a CD1d-restricted fashion. These findings suggest what we believe to be a novel pathway that can regulate AHR, and a new therapeutic strategy (treatment with glycolipid activators of this NKT cell population) for asthma.

A comparative study of DPSK and OOK WDM transmission over transoceanic distances and their performance degradations due to nonlinear phase noise

Abstract: We have compared experimentally the transmission performance of return-to-zero differential phase-shift keying (RZ-DPSK) with RZ-ON-OFF keying (OOK), nonreturn-to-zero differential phase-shift keying (NRZ-DPSK), and NRZ-OOK for 100/spl times/10-Gb/s transmission with a spectral efficiency of 0.22 b/s/Hz over transoceanic distances. The Q degradation of the RZ-DPSK after transmission over 9180 km was 3 dB greater than that of RZ-OOK. The experimental results clearly showed the major cause of degradation for DPSK is not cross-phase modulation but self-phase modulation. The calculated nonlinear phase noise, i.e., the Gordon-Mollenauer effect, agreed with the experimental results. A distributed-Raman-amplifier assisted erbium-doped-fiber-amplified transmission line acted well in reducing the nonlinear phase noise.

Method of image feature coding and method of image search

Abstract: A feature coding unit extracts and encodes a feature of a video signal so as to generate a feature stream. A feature identifying unit checks a decoded feature obtained as a result of decoding the feature stream against a search key from a user for a match so that a video content requested by the user is retrieved.
