    Notes: In this study, ferroelectric thin films of Ba(Zr0.1Ti0.9)O3 were successfully deposited onPt/Ti/SiO2/Si substrate under the optimal rf magnetron sputtering parameters, and their electrical andferroelectric characteristics were investigated. The MFMIS structure of Al/Ba(Zr0.1Ti0.9)O3/Pt/Ti/SiO2/Si was proposed in order to be applied as NDRO FRAM applications. From theexperimental results obtained, the dielectric constant and the leakage current density of BZT filmswere about 200 and 1×10-9A/cm2, respectively, under the electrical field of 1 MV/cm. Besides, thesaturation polarization and coercive field of Ba(Zr0.1Ti0.9)O3 films were found to be 4 μC/cm2 and 25kV/cm, respectively, as the frequency of 103 Hz was applied. The variations of saturation polarizationand coercive filed of films under various frequencies ranging form 102 to 106 Hz were also discussed

    Notes: Manufacturing execution system (MES) is a computer application system that integrates all relevant real-time information along every step in a manufacturing process. MES is essential for manufacturers for gathering real-time production line information, supporting manufacturing decision making and increasing manufacturing efficiency. MES is a must for operation control and lot tracking in the shop floor of a plant with complicated manufacturing processes, such as semiconductor manufacturing fab or TFT-LCD manufacturing plant. This paper presents theformulization of performance measurement of implementing MES from several quantitative and qualitative aspects by analyzing the basic functions and objectives of MES and interviewing with some senior consultants and MES related working staff. In addition, multi-attribute decision making technique, analytic hierarchy process (AHP) is used to decide the priority of these performancemeasurement indices. The results of this research will be useful for a company when MES is an existing system or is a To Be system

    Notes: A new approach to obtain Si nanostructures on insulating layer is proposed by laser irradiation onultra-thin hydrogenated amorphous silicon (a-Si:H) films with subsequently thermal annealing. Itwas found that the surface nanostructuring was occurred when the laser fluence exceeded thethreshold value as revealed by AFM images. The size and area density of formed Si nanostructureswere depended on the laser fluence and film thickness while thermal annealing played an importantrole in the size and its distribution. The results showed that a high density (〉1011cm-2) Sinanostructures with average lateral size of 10-20nm can be achieved by the present technology

    Notes: We study the elliptic Cn and BCn Ruijsenaars–Schneider models which are elliptic generalization of systems given in previous paper by the present authors [Chen et al., J. Math. Phys. 41, 8132 (2000)]. The Lax pairs for these models are constructed by Hamiltonian reduction technology. We show that the spectral curves can be parametrized by the involutive integrals of motion for these models. Taking nonrelativistic limit and scaling limit, we verify that they lead to the systems corresponding to Calogero–Moser and Toda types. © 2001 American Institute of Physics.

    Neurons Overexpressing Heme Oxygenase-1 Resist Oxidative Stress-Mediated Cell Death (2000)

    Notes: Abstract : This is the first report on the protective effect of heme oxygenase-1 (HO-1) overexpression against oxidative stress-mediated neuronal cell death and demonstration of a decreased production of oxygen free radicals when HO-1 levels are increased. HO-1 is the heat shock/stress cognate of the heat shock protein 32 family of proteins. A known function of these proteins is α-meso bridge-specific cleavage of the heme molecule. For the present study, we used cerebellar granular neurons (CGNs) isolated from homozygous transgenic (Tg) mice that overexpress HO-1 under neuron-specific enolase control and nontransgenic (Ntg) littermates. The Tg mouse CGNs were characterized by increased levels of HO-1 mRNA and protein, a lower resting intracellular calcium concentration, and a reduced HO-1 transcriptional response to glutamate-mediated oxidative stress. Compared with the Ntg neurons, when exposed to glutamate (30 μM or 3 mM), the magnitude of cell viability was increased and the number of cells exhibiting membrane permeability and chromatin condensation were significantly decreased in the Tg CGN cultures. The population of neurons surviving glutamate toxicity decreased when HO-1 activity was inhibited by a peptide inhibitor. The neuroprotective effect by HO-1 was extended to H2O2-induced cell death. The mechanism of protection may involve in part a reduced production of reactive oxygen species upon exposure to glutamate. We suggest that induction of HO-1 by pharmacological means may be a novel approach to amelioration of oxidative insults to neurons.

    Different roles of α1-adrenoceptor subtypes in mediating cardiomyocyte protein synthesis in neonatal rats (2004)

    Notes: 1. Three different α1-adrenoceptor subtypes, designated α1A, α1B and α1D, have been cloned and identified pharmacologically in cardiomyocytes. In vitro studies have suggested that α1-adrenoceptors play an important role in facilitating cardiac hypertrophy. However, it remains controversial as to which subtype of α1-adrenoceptors is involved in this response. In the present study, we investigated the different role of each α1-adrenoceptor subtype in mediating cardiomyocyte protein synthesis, which is a most important characteristic of cardiac hypertrophy in cultured neonatal rat cardiomyocytes.2. Cardiomyocyte hypertrophy was monitored by the following characteristic phenotypic changes: (i) an increase in protein synthesis; (ii) an increase in total protein content; and (iii) an increase in cardiomyocyte size.3. The role of each α1-adrenoceptor subtype in mediating cardiomyocyte protein synthesis was investigated by the effect of specific α1-adrenoceptor subtype-selective antagonists on noradrenaline-induced [3H]-leucine incorporation. In addition, pKB values for α1-adrenoceptor subtype-selective antagonists were calculated and compared with the corresponding pKi values to further identify their effects.4. Activation of α1-adrenoceptors by phenylephrine or noradrenaline in the presence of propranolol significantly increased [3H]-leucine incorporation, protein content and cell size.5. Pre-incubating cardiomyocytes with 5-methyl-urapidil, RS 17053 or WB 4101 significantly inhibited noradrenaline-induced [3H]-leucine incorporation. However, there was no effect when cardiomyocytes were pre-incubated with BMY 7378. The correlation coefficients between pKB values for α1-adrenoceptor subtype-selective antagonists and pKi values obtained from cloned α1A-, α1B- or α1D-adrenoceptors were 0.92 (P 〈 0.01), 0.66 (P 〉 0.05) and 0.24 (P 〉 0.05), respectively.6. Our results suggest that the α1-adrenoceptor is dominantly responsible for adrenergic hypertrophy of cultured cardiomyocytes in neonatal rats. The efficiency in mediating cardiomyocyte protein synthesis is α1A 〉 α1B ≫ α1D.

    Abdominal Sonography Screening of Clinically Diagnosed or Suspected Appendicitis before Surgery (1998)

    Notes: Abstract. We conducted a prospective study to evaluate the value of abdominal sonography in the diagnosis of acute appendicitis and determine the need for abdominal sonography before operation. Altogether 191 patients with clinically diagnosed or suspected appendicitis underwent an abdominal sonography examination performed by a staff surgeon before operation. The sonographic findings are classified into three categories: appendicitis, other diseases, or normal screening. A total of 158 patients (82.7%) with positive findings of appendicitis proceeded to surgery; 18 patients (9.4%) were found to have other diseases, and they were treated for their conditions; and 15 patients (7.9%) with normal screening were discharged from the hospital and were reevaluated 2 weeks later. Only one patient had a false-negative finding. Of the 158 patients undergoing operation, 143 (90.5%) were proved to have appendicitis by the pathologic reports. A total of 32 negative appendectomies (16.8%) were prevented after sonographic examination. Abdominal sonography for detecting acute appendicitis had a sensitivity of 99.3%, a specificity of 68.1%, an accuracy of 91.6%, a positive predictive value of 90.5%, and a negative predictive value of 97.0%. The value of meticulous history-taking, physical examination, and laboratory tests cannot be overemphasized. Our experience suggests that patients with clinically diagnosed or suspected acute appendicitis should routinely undergo abdominal sonography examination, performed by an experienced surgeon, to further decrease the negative appendectomy rates.
