In this paper, we present a high-performance - main-profile decoder for high-definition (HD) video applications, which can decode HD 720p video streams with 30fps at 80MHz. We implemented the decoder with a one-poly eight-metal 0.13μm CMOS process, which contains about 261, 900 logic gates and on-chip memories of 13.9KB SRAM and 13.1KB ROM and occupies an area of about 5.1mm². In designing the - decoder, we used a template-based SoC design flow, with which we performed the design space exploration of the decoder by trying various configurations of communication channels. Moreover, we also describe architectures of the computation blocks optimized to satisfy the requirements of - HD applications.

The formula of the syllabic structure of the English words is (C³)(C²)(C¹)V(C₁)(C₂)(C₃)(C₄). Examples may be given:
: strong/stro_??_/
C¹V: see/si_??_/
: length/le_??_kθ/
: absence/æbsns/.
Swahili has the following formula: (C³) (C²) (C¹) V.
V: ona /o-na/‘to see’
C¹V: ja/ja/‘to come’
C²C¹V: anza/a-nza/‘to begin’
C³C²C¹V: hamstashara/ha-msta-ša-ra/‘fifteen’
Thus, syllables in Swahili regularly end in vowels. Many loan-words taken from English, therefore, have adapted their syllabic structure to that of Swahili, changing their one-syllable type into two- or three-syllable one.
C¹V-C¹V (<E. ): basi/ba-si/ (<E. bus/bas/)
C¹V-C²C¹V (<E. ): banki/ba-nki/ (<E. bank/bæ_??_k/)
C²C¹V-C¹V (<E. ): brashi/bra-ši/ (<E. brush/braš/)
C²C¹V-C²C¹V (<E. ): stampa/sta-mpa/ (<E. stamp/stæmp/)
C¹V-C²C¹V-C¹V (<E. ): sampuli/sa-mpu-li/ (<E. sample/sæmpl/)
C¹V-C¹V-C¹V (<E. ): dazani/da-za-ni/ (<E. dozen/dazn/)
Some words have the same syllabic structure as the original ones.
V-C¹V (<E. V-C¹V): eka/e-ka/ (<E. acre/ei-k_??_/)
C¹V-C¹V (<E. C¹V-C¹V): gita/gi-ta/ (<E. guitar/gi-ta_??_/)

チタンマグネリ相(Ti4O7)における電界誘起構造相転移を観測した。Ti4O7はTiイオンあたりｄ電子0.5個をもち常温で金属相をとるが、154Kでバイポーラロン形成による半導体相へ、140Ｋでバイポーラロンの秩序化による電荷整列絶縁体相へと転移する。本来、電荷秩序絶縁相が安定な領域である７７Ｋにおいて、Ti4O7単結晶のｂ軸方向に高電界を印加すると、閾値において突然約３桁抵抗減少を観測した、電界を除去すると閾値　　　Ｖｃ２（＞Ｖｃ２）で再び絶縁体へと転移する。この変化は可逆であり電圧の印加除去を繰り返しても、Ｖｃ２の値は変化しない。抵抗変化幅は約３桁であり、これは電荷整列相から中間半導体相への抵抗変化分に相当する。この現象は高電界印加をトリガーとして電荷秩序が崩れ、相転移を誘発したことに相当すると考えている。

Thermohydrodynamic description of adiabatic flow of He II, in which the high velocity region up to 100cm/s was studied, is given with a new-type mutual friction force. Experiments consist of various thermodynamic measurements and the NMR study of the motion of ³He atoms added to the system. There appeared various stages of the flow state of superfluid He II. Especially, there exist clearly two characteristic velocities and v_c2. An interpretation of the results is given with the pinning-depinning model of quantized vortices, in which we made a conjecture that quantized vortices construct vortex-bundles in the presence of pinning-centers.

We propose a VLSI design of Multi-Format Decoder (MFD) to support multiple video codec standards such as MPEG-2, MPEG-4, H.264 and -. A decoupled MFD architecture is introduced in order to easily add or remove the codecs. The decoupled architecture preserves the stability of the previously designed and verified codecs. It also reduces the gate count by sharing the large-size common resources. The design size is 2.4M gates and the operating clock frequency is 225MHz in the 65nm process.

  The temperature dependence of the magnetic viscosity coefficient Sv and average anisotropy field H_A(ave) were examined for Ba-ferrite fine particles having mean particle volume V of 3.2 × 10^-17 cm³, in the temperature range from 200 to 413K. A study was done for the relationship between the activation volume ν calculated based on Sv and average anisotropy constant K_A(ave) for Ba-ferrite fine particles. This experiment showed that the temperature dependence of Sv is the same as that of coercive force Hc, and Sv increases with the increase of the temperature. H_A(ave) linearly increases as the temperature increases in the temperature range from 293 to 413 K. The activation volume ν is inversely proportional to K_A(ave). The values of ν and the critical volume Vc for superparamagnetic behaviour at 293K, are approximately 1.35 × 10^-17 and 0.23 × 10^-17 cm³, respectively. Larger K_A(ave) value is necessary for smaller ν value which is an important factor for high-density magnetic recording. Also, the relations V/ν › 1 and V/ ›› are of significant importance.

The characteristics of stress corrosion cracking (SCC) of Al-4%Cu alloy were investigated in 0.1mol/kg-H₂SO₄+1mol/kg-NaNO₃+0.05mol/kg-NaCl solution with reference to faceting dissolution and crystallographic planes of the fracture surfaces. Fracture time decreased exponentially with increasing potential above the stationary pitting potential, =.66 (vs. SCE), determined under no stressing. The kinds of facet were {100} and/or {110}, regardless of electrode potentials tested. There were many {100} steps and {110} facet pits formed by {100} and {110} faceting dissolution on the fracture surface. Cracks issued directly from the specimen surface at potentials near V_c, and issued from bottoms of pits at the increased potentials. Ductile fracture occured by reduction of area due to fast pitting at noble potentials than 1.80V. These results imply an important relationship between SCC and {hkl} faceting dissolution.

母音と子音をどのように音節にまとめるかという問題は,分節(syllabification)の過程に現れる。本研究は,英語話者と日本語話者が,語中に2つの子音を持つ2音節からなる英単語と無意味語をどのように分けるかを調べた。英語の音節を認識する訓練を受けた日本語話者も参加した。口頭課題では参加者は英単語と無意味語の語中にポーズを挿人した。筆記課題では自然と思われる英単語の分節を3つの候補から選んだ。一般的な分節の型は子音群を分けるものであったが(例:mas/ter),好まれる分節のタイプは各々の言語の典型的な音節の型の影響を受け,3グループ間で異なった。音素配列制約,母音長,形態的知識はどのグループにも影響を与えたが,強勢の位置は莫語話者のみに影響した。課題や材料の種類も分節に影響した。分節に関する言語学・心理言語学的理論の観点から結果を考察した。

Osteogenic disorder (ODS) mutant rats unable to synthesize vitamin C (VC), were employed in this study of the effects of marginal VC deficiency on aortic endothelial cells. The marginal VC-deficient ODS rats (group 1, n=10) were fed a VC-free diet and given water containing (mg/ml) once a week to prevent scurvy. The control ODS rats (group 2, n=8) received the same VC-free diet, but with the same dosage of VC daily in their drinking water. Blood VC concentrations in group 1 and 2 were 0.71±0.11mg/dl (n=5) and 1.10±0.08mg/dl (n=4), respectively. Scanning electron microscopy showed shrinkage and protrusion into the arterial lumen of endothelial cells from VC-deficient ODS rats. Transmission electron microscopy revealed a decreased number of mitochondria and vacuole formations in the cytoplasm of group 1 aortic endothelial cells, and the occasional appearance of migrant macrophages in the widened subendothelial space. Since endothelial cell injury is recognized to trigger atherosclerosis, we conclude that VC deficiency is a likely initiator of atherosclerosis.

Information-theoretic security and computational security are fundamental paradigms of security in the theory of cryptography. The two paradigms interact with each other but have shown different progress, which motivates us to explore the intersection between them. In this paper, we focus on Multi-Party Computation (MPC) because the security of MPC is formulated by simulation-based security, which originates from computational security, even if it requires information-theoretic security. We provide several equivalent formalizations of the security of MPC under a semi-honest model from the viewpoints of information theory and statistics. The interpretations of these variants are so natural that they support the other aspects of simulation-based security. Specifically, the variants based on conditional mutual information and sufficient statistics are interesting because security proofs for those variants can be given by information measures and factorization theorem, respectively. To exemplify this, we show several security proofs of BGW (Ben-Or, Goldwasser, Wigderson) protocols, which are basically proved by constructing a simulator.

Combinations of cysteine, ascorbic acid, and pyridoxine are frequently used in oral formulations. Although there have been many reports on the efficacy of each of these ingredients, little information is known about their combined effects on skin cells. The purpose of this study was to evaluate the combined effects of cysteine, ascorbic acid, and pyridoxine, as well as the effect of adding α-lipoic acid, on skin cells. Human keratinocytes were treated with individual antioxidants or combinations of them, and glutathione levels and expression of glutathione synthesis-related genes were measured. The combination of cysteine, ascorbic acid, and pyridoxine increased the expression of γ-GCSc and tended to increase glutathione levels compared to the controls. Interestingly, the addition of α-lipoic acid further increased glutathione levels by increasing the expression of CD98. Similarly, in 3D-human skin models, the combination of cysteine, ascorbic acid, and pyridoxine promoted glutathione synthesis, and this effect was enhanced by the addition of α-lipoic acid. Furthermore, melanin synthesis inhibition was shown to be dependent on increased glutathione levels. These results suggest that the addition of α-lipoic acid to the combination of cysteine, ascorbic acid, and pyridoxine enhances glutathione production and may have anti-aging effects through efficient oxidative stress reduction.

パラジウム塩を触媒とする塩化ビニルからの酢酸ビニル合成反応について検討した。本反応はパラジウム塩に対して接触的に起り,反応後金属パラジウムの析出は全く認められなかった。ソジウムクロロパラデートを触媒とする反応では,酢酸ビニル生成速度度は酢酸塩添加量に最も強く支配された。酢酸パラジウムを触媒とする場合には,酢酸パラジウム1molによって約1.5molの塩化ビニルが反応し,酢酸ビニルとアセトアルデヒドを与え,反応後塩化パラジウムが析出した。また,酢酸パラジウムを触媒に用いると,酢酸およびジメチルホルムアミド中では酢酸ビニル生成反応が起こるが,トルエン中では全く起こらなかった。反応機構として配位子交換反応が考えられた。

In diabetic patients, glucolipotoxicity induces multiple defects in β-cells. Furthermore, increasing evidence also confirms the direct interaction between the adipocytes and β-cells. The beneficial efficacy of vitamin C (Vc) on β-cells is rarely investigated. In this study, INS-1 832/13 β-cells were cultured with high levels of glucose and free fatty acid (FFA) or cocultured with 3T3-L1 adipocytes in the presence or absence of Vc. Vc decreased glucolipotoxicity-induced cell mass loss by reducing apoptosis and reactive oxidative species (ROS). After treatment with elevated glucose and FFA, β-cell secretion dysfunction was evidenced and was partially improved by 1, 10 and 50 μg/mL Vc treatment. In the coculture system, impaired secretion function was also moderately normalized upon addition of 10 and 50 μg/mL Vc to the coculture medium (p<0.05). Vc at 50 μg/mL significantly (p<0.05) inhibited the fatty acid release from adipocytes to the coculture medium. Meanwhile, the elevated ROS of cocultured β-cells was decreased in the presence of ( to 50 μg/mL). In both induction methods, intracellular TGs in both β-cells and adipocytes were decreased by Vc treatment; however, Vc did not affect the intracellular insulin level. Moreover, IL-6 and adiponectin levels in the coculture medium remained under the levels of the control group. The positive effects of Vc might be due to the antioxidant capacity and TG inhibitory effect of Vc.

A novel dual feedback looped chaotic integrated circuit driven by a three-phase non-overlapping clock is presented. The proposed circuit consists of four MOS switches for S/H (sample and hold), a level shifter and two nonlinear functions for nonlinearity in the feedback. After optimizing of nonlinear functions for chaotic signal generation, the proposed circuit was simulated with SPICE program using a 0.6µm CMOS process parameter. For various control voltages, its chaotic dynamics such as time waveform, frequency spectra and bifurcation diagram were analyzed. We confirmed that the circuit can generate discrete chaotic signals in specific control voltages.
