Effect of O/Zn Flux Ratio on Crystalline Quality of ZnO Films Grown by Plasma-Assisted Molecular Beam Epitaxy (2003)

The effect of O/Zn flux ratio on the crystalline quality of ZnO films grown at 700°C by plasma-assisted molecular beam epitaxy was investigated. Zinc beam flux (FZn) was varied from 2.2≤FZn≤8.3 Å/s with an O2 flow rate of 3 sccm and RF power of 300 W. The surface morphology of the ZnO layers strongly depended on FZn. ZnO epilayers grown under stoichiometric flux conditions (i.e., FZn=5.1 Å/s) had high crystalline quality, as was confirmed by using X-ray diffraction, photoluminescence (PL), and Hall-effect measurements: the full width at half maximum (FWHM) of a skew symmetric (1010) X-ray rocking curve was 720 arcsec; the dominant neutral donor bound exciton emission intensity in the PL spectra became maximum with the narrowest FWHM; the electron mobility was a maximum of 130 cm2V-1s-1; and a residual carrier concentration of 1.2×1017 cm-3 was achieved. We demonstrated that stoichiometric ZnO films have the lowest dislocation density and the highest electron mobility compared with ZnO films grown under nonstoichiometric flux conditions.
Genomic and Morphological Changes of Neuroblastoma Cells in Response to Three-Dimensional Matrices (2007)

Advances in neural tissue engineering require a comprehensive understanding of neuronal growth in 3 dimensions. This study compared the gene expression of SH-SY5Y human neuroblastoma cells cultured in 3-dimensional (3D) with those cultured in 2-dimensional (2D) environments. Microarray analysis demonstrated that, in response to varying matrix geometry, SH-SY5Y cells exhibited differential expression of 1,766 genes in collagen I, including those relevant to cytoskeleton, extracellular matrix, and neurite outgrowth. Cells extended longer neurites in 3D collagen I cultures than in 2D. Real-time reverse transcriptase polymerase chain reaction experiments and morphological analysis comparing collagen I and Matrigel tested whether the differential growth and gene expression reflected influences of culture dimension or culture material. SH-SY5Y neuroblastoma cells responded to geometry by differentially regulating cell spreading and genes associated with actin in similar patterns for both materials; however, neurite outgrowth and the expression of the gene encoding for neurofilament varied with the type of material. Electron microscopy and mechanical analysis showed that collagen I was more fibrillar than Matrigel, with larger inter-fiber distance and higher stiffness. Taken together, these results suggest complex cell-material interactions, in which the dimension of the culture material influences gene expression and cell spreading and the structural and mechanical properties of the culture material influence gene expression and neurite outgrowth.
Noureseothricin (streptothricin) inactivated by a plasmid pIE636 encoded acetyl transferase of Escherichia coli: Location of the acetyl group (1993)

Escherichia coli strains harbouring the plasmid pIE636 are able to synthesize acetylcoenzyme A: streptothricin acetyltransferase (ACSAT). The (enzymatic) N-acetylation of streptothricin F is known to contribute significantly towards the loss of antibacterial activity. 13C-NMR analysis of [14C]N-acetyl-labelled streptothricin F, produced by ACSAT-catalysed acetylation of streptothricin F and subsequent purification by various chromatographical steps, unequivocally revealed streptothricin F to be acetylated at the β-amino group (C16) (and not at the ε-amino group (C19)).
The Multiple Functions of TRBP, at the Hub of Cell Responses to Viruses, Stress, and Cancer (2012)

The TAR RNA binding protein (TRBP) has emerged as a key player in many cellular processes. First identified as a cellular protein that facilitates the replication of human immunodeficiency virus, TRBP has since been shown to inhibit the activation of protein kinase R (PKR), a protein involved in innate immune responses and the cellular response to stress. It also binds to the PKR activator PACT and regulates its function. TRBP also contributes to RNA interference as an integral part of the minimal RNA-induced silencing complex with Dicer and Argonaute proteins. Due to its multiple functions in the cell, TRBP is involved in oncogenesis when its sequence is mutated or its expression is deregulated. The depletion or overexpression of TRBP results in malignancy, suggesting that the balance of TRBP expression is key to normal cellular function. These studies show that TRBP is multifunctional and mediates cross talk between different pathways. Its activities at the molecular level impact the cellular function from normal development to cancer and the response to infections.
Evolution of intelligent network deployment in Taiwan's mobile networks (2003)

IN services have been launched in the wired network for more than four years in Taiwan. The number of wired IN service subscribers grows slowly. However, the IN-based prepaid service for mobile subscribers has more than 1 million users in its first launch year. The rate of prepaid service subscribers to total mobile subscribers is greater than sixteen percent and grows predictably. In addition, many value-added services are introduced to differentiate mobile networks. These value-added services will be enhanced as the intelligence capability of IN can be improved. There is no doubt that services based on IN will be prosperous and welcomed as Internet fever warms up in the wired-wireless convergent network.
Critical role of protein kinase C ε for lipopolysaccharide-induced IL-12 synthesis in monocyte-derived dendritic cells (2002)

In the present study we have investigated the potential involvement of protein kinase C (PKC) in the maturation of human dendritic cells (DC) by bacterial lipopolysaccharide (LPS). LPS stimulation of DC derived from human monocytes resulted in PKC phosphorylation. Inhibition of PKC activation using bisindolylmaleimide (Bis), a pan-PKC inhibitor, was associated with a dose-dependent decrease of LPS-induced IL-12 production. In contrast, up-regulation of MHC class II, CD80 and CD86 was not altered. Consistent with the diminished IL-12 synthesis, DC stimulated with LPS in presence of Bis were deficient in the induction of IFN-gamma production by allogeneic CD4+ T cells. Furthermore, we found that PKC inhibition impaired LPS-induced I kappa B-alpha degradation and subsequent nuclear factor (NF)-kappa B activation in DC. LPS resulted in the phosphorylation of conventional alpha/beta and novel epsilon PKC isoforms in DC. Inhibition of LPS-induced PKC activity using pseudosubstrate peptides specific for PKC isoforms established that PKC epsilon but not PKC alpha/beta was involved in the production of IL-12 and TNF-alpha. Overall, these data provide evidence that PKC inhibition impairs LPS signaling in DC and identify PKC epsilon as a potential target for the inhibition of Toll-like receptor-4-mediated, IL-12-dependent Th1 type responses.

Further studies on the regulation, localization and function of the TRH-like peptide pyroglutamyl-glutamyl-prolineamide in the rat anterior pituitary gland (1995)

Recent evidence shows that thyrotrophin-releasing hormone (TRH) immunoreactivity in the rat anterior pituitary gland is accounted for by the TRH-like tripeptide pyroglutamyl-glutamyl-prolineamide (pGlu-Glu-ProNH2, < EEP-NH2). The present study was undertaken to investigate further the regulation, localization and possible intrapituitary function of < EEP-NH2. Anterior pituitary levels of < EEP-NH2 were determined between days 5 and 35 of life, during the oestrous cycle and after treatment with the luteinizing hormone-releasing hormone (LHRH) antagonist Org 30276. Treatment of adult males with the LHRH antagonist either for 1 day (500 micrograms/100 g body weight) or for 5 days (50 micrograms/100 g body weight) reduced anterior pituitary < EEP-NH2 levels by 25-30% (P < 0.05 versus saline-treated controls). Anterior pituitary < EEP-NH2 increased between days 5 and 35 of life. In females, these levels were 2- to 3-fold higher (P < 0.05) than in males between days 15 and 25 after birth; these changes corresponded with the higher plasma follicle-stimulating hormone (FSH) levels in the female rats. After day 25, < EEP-NH2 levels in female rats decreased in parallel with a decrease in plasma FSH. Injections with the LHRH antagonist (500 micrograms/100 g body weight), starting on day 22 of life, led to reduced contents of < EEP-NH2 in the anterior pituitary gland of female rats on days 26 and 30 (55 and 35% decrease respectively). Levels of < EEP-NH2 in the anterior pituitary gland did not change significantly during the oestrous cycle.(ABSTRACT TRUNCATED AT 250 WORDS)
Vertical GaN-Based Light-Emitting Diodes Structure on Si(111) Substrate with Through-Holes (2010)

A novel vertical GaN-based light-emitting diode (LED) structure on a Si(111) substrate with through-holes was reported in this letter. The through-holes were formed by dry etching from the n-GaN layer to the Si substrate. Metals connecting the n-GaN layer and Si substrate were used to fill the holes. The series resistances induced by the AlN buffer layer and other interlayers were shorted by the metals filling the holes. Compared with those of the conventional LED structure, the series resistance and operating voltage at 20 mA were reduced from 26 to 22.5 Ω, and from 4.4 to 4.0 V, respectively. Light output intensity shows an increase of 29%.

This paper describes the implementation of a car handsfree speech enhancement application on a TI TMS320C54x DSP. This fixed-point DSP family is especially suited for wireless applications and it is shown how, by taking full advantage of the DSP architecture and instruction set, advanced wireless speech processing applications can be efficiently implemented on these devices. The performances of the complete speech enhancement application in a car environment are presented, showing that even with a fixed-point arithmetic implementation, high performances close to a floating point implementation can be achieved.
Goldindec: A Novel Algorithm for Raman Spectrum Baseline Correction (2015)

Raman spectra have been widely used in biology, physics, and chemistry and have become an essential tool for the studies of macromolecules. Nevertheless, the raw Raman signal is often obscured by a broad background curve (or baseline) due to the intrinsic fluorescence of the organic molecules, which leads to unpredictable negative effects in quantitative analysis of Raman spectra. Therefore, it is essential to correct this baseline before analyzing raw Raman spectra. Polynomial fitting has proven to be the most convenient and simplest method and has high accuracy. In polynomial fitting, the cost function used and its parameters are crucial. This article proposes a novel iterative algorithm named Goldindec, freely available for noncommercial use as noted in text, with a new cost function that not only conquers the influence of great peaks but also solves the problem of low correction accuracy when there is a high peak number. Goldindec automatically generates parameters from the raw data rather than by empirical choice, as in previous methods. Comparisons with other algorithms on the benchmark data show that Goldindec has a higher accuracy and computational efficiency, and is hardly affected by great peaks, peak number, and wavenumber.
Novel<i>N</i>-Acetyl Bioisosteres of Melatonin: Melatonergic Receptor Pharmacology, Physicochemical Studies, and Phenotypic Assessment of Their Neurogenic Potential (2015)

Herein we present a new family of melatonin-based compounds, in which the acetamido group of melatonin has been bioisosterically replaced by a series of reversed amides and azoles, such as oxazole, 1,2,4-oxadiazole, and 1,3,4-oxadiazole, as well as other related five-membered heterocycles, namely, 1,3,4-oxadiazol(thio)ones, 1,3,4-triazol(thio)ones, and an 1,3,4-thiadiazole. New compounds were fully characterized at melatonin receptors (MT1R and MT2R), and results were rationalized by superimposition studies of their structures to the bioactive conformation of melatonin. We also found that several of these melatonin-based compounds promoted differentiation of rat neural stem cells to a neuronal phenotype in vitro, in some cases to a higher extent than melatonin. This unique profile constitutes the starting point for further pharmacological studies to assess the mechanistic pathways and the relevance of neurogenesis induced by melatonin-related structures.

Critical phenomena near structural phase transitions studied by EPR (1974)

Abstract Critical phenomena observed by electron paramagnetic resonance (EPR) near the phase transitions of SrTiO3 and LaA1O3 are reviewed. A short description of the second-order antiferrodistortive transitions in these compounds is first given. Then high accuracy EPR Fe3+ measurements of the temperature dependence of the (rotational) order parameter φ are described. These show the existence of a critical region near Tc in both compounds which scale and yield the static critical exponents β and γ. A survey of the EPR linewidfh broadening of the Fe3 +-VO, centre in SrTiO3 due to the critical slowing down of local order parameter fluctuations follows. The frequency width Δ ω(T) of the local spectral density narrows strongly on approaching Tc . Close to Tc a quasi-static regime is created. This allows a determination of the probability distribution P(φl) from the EPR lineshapes. P(φl) deviates from a Gaussian closely above and below Tc.
Supporting automatic configuration of component-based distributed systems (1999)

Recent developments in Component technology enable the construction of complex software systems by assembling together off-the-shelf components. However, it is still difficult to develop efficient, reliable, and dynamically configurable component based systems. Components are often developed by different groups with different methodologies. Unspecified dependencies and behavior lead to unexpected failures. Component-based software systems must maintain explicit representations of inter-component dependence and component requirements. This provides a common ground for supporting fault-tolerance and automating dynamic configuration. In this paper, we present a generic model for reifying dependencies in distributed component systems and discuss how it can be used to support automatic configuration. We describe our experience deploying the framework in a CORBA-compliant reflective ORB and discuss the use of this model in a new distributed operating system.
Direct Arylation/Alkylation/Magnesiation of Benzyl Alcohols in the Presence of Grignard Reagents via Ni-, Fe-, or Co-Catalyzed sp<sup>3</sup> C–O Bond Activation (2012)

Direct application of benzyl alcohols (or their magnesium salts) as electrophiles in various reactions with Grignard reagents has been developed via transition metal-catalyzed sp(3) C-O bond activation. Ni complex was found to be an efficient catalyst for the first direct cross coupling of benzyl alcohols with aryl/alkyl Grignard reagents, while Fe, Co, or Ni catalysts could promote the unprecedented conversion of benzyl alcohols to benzyl Grignard reagents in the presence of (n)hexylMgCl. These methods offer straightforward pathways to transform benzyl alcohols into a variety of functionalities.
Suppression of Free-Surface Effects from Multicomponent Sea-Floor Data (2000)

We use multicomponent sea-floor data to suppress receiver-side ghosts and freesurface multiples and to datum the results of ghosts and multiple suppression from the sea-floor to the free-surface. Both steps – deghosting and multiple suppression - are applied trace by trace to the tau-p transformed common receiver gathers. Datuming for 2D structures with inline lateral variations is performed in the same tau-p domain. Therefore effective suppression of aliasing in the tau-p transform is of crucial importance. In addition to the dip filter our antialiasing protection is based on simple scaling of the results of the transform for high frequencies. The synthetic and real data examples illustrate that the total scheme performs well and is computationally efficient.
Evaluation of chemical and biological consequences of soil sterilization methods (2007)

Sterilized soils are commonly used for the study of xenobiotic sorption and as an abiotic control in biodegradation experiments. They are also used for the chemical study of nitrogen and carbon cycle processes and the elimination of the biological factors. In this research the effects of different soil sterilization methods such as autoclaving, fumigating and exposure to ultraviolet and microwave irradiation on soil chemical and biological properties (soil acidity, electrical conductivity, cation exchange capacity, optical density, extractable carbon and nitrogen and colony forming unit) were examined under laboratory conditions. All the sterilization methods significantly (at P<0.05) decreased pH and increased electrical conductivity (EC), optical density (OD), extractable carbon and nitrogen as compared to nonsterilized soil samples. The results showed that autoclaving method was the most effective method in eliminating soil microorganisms and ultra violet irradiation was the less effective one. These induced changes were likely due to release of soluble organic acids from humic materials and dead microorganisms.
