In this paper, we design a microcavity with vertical and in-plane emissions by applying double hetero-structure with mode-gap confinement in photonic crystal waveguide. The hetero-structure is formed by modulating the waveguide width locally by slightly shifting the positions of several nearest air-holes outward. By numerical calculations, we simulate the basic mode profiles and quality (Q) factors of each resonance mode. After optimizing the cavity, high simulated Q factor of 110 000 is obtained. From the well-fabricated devices, we observe the lasing emissions with Q factor of 3200 at wavelength of 1593 nm from both vertical and in-plane directions and address the lasing mode by comparing the measured results with the simulated ones. From the simulated heat transition behaviors by finite-element method, we observe the better heat dissipation provided by the waveguide region in this microcavity. This microcavity laser with locally modulated design could be potentially served as a light source with less influence on the nearby components in photonic integrated circuits.

The present invention proposes a method and apparatus for decoding BCH codes and Reed-Solomon codes, in which a modified Berlekamp-Massey algorithm is used to perform the decoding process and the efficiency of the decoder can be improved by re-defining the error locating polynomial as a reverse error locating polynomial, while the operation of the decoding process can be further realized by a common re-configurable module. Furthermore, the architecture of the decoder is consisted of a plurality of sets of re-configurable modules in order to provide parallel operations with different degrees of parallel so that the decoding speed requirement of the decoder in different applications can be satisfied.

A light-detecting device structure comprises a substrate, a vertical organic light-emitting transistor and a light-detecting unit, wherein the vertical organic light-emitting transistor is disposed at a first location on the substrate, and the light-detecting unit is disposed at a second location on the substrate, in which the first and the second locations can be spaced out an appropriate distance as needed. The vertical organic light-emitting transistor emits a light to an object, and the light-detecting unit receives a reflected light from the object. The reflected light received is analyzed to determine a distance between the light-detecting device structure and the object, as well as a shape or a composition of the object.

Brain extraction from head magnetic resonance (MR) images is a classification problem of segmenting image volumes into brain and non-brain regions. It is a difficult task due to the convoluted brain surface and the inapparent brain/non-brain boundaries in images. This paper presents an automated, robust, and accurate brain extraction method which utilizes a new implicit deformable model to well represent brain contours and to segment brain regions from MR images. This model is described by a set of Wendland's radial basis functions (RBFs) and has the advantages of compact support property and low computational complexity. Driven by the internal force for imposing the smoothness constraint and the external force for considering the intensity contrast across boundaries, the deformable model of a brain contour can efficiently evolve from its initial state toward its target by iteratively updating the RBF locations. In the proposed method, brain contours are separately determined on 2D coronal and sagittal slices. The results from these two views are generally complementary and are thus integrated to obtain a complete 3D brain volume. The proposed method was compared to four existing methods, Brain Surface Extractor, Brain Extraction Tool, Hybrid Watershed Algorithm, and Model-based Level Set, by using two sets of MR images as well as manual segmentation results obtained from the Internet Brain Segmentation Repository. Our experimental results demonstrated that the proposed approach outperformed these four methods when jointly considering extraction accuracy and robustness. (C) 2009 Elsevier B.V.

In this paper we describe a graft polymerization/solvent immersion method for generating various patterns of polymer brushes. We used a very-large-scale integration (VLSI) process and oxygen plasma system to generate well-defined patterns of polymerized methyl methacrylate (MMA) on patterned Si(1 0 0) surfaces through atom transfer radical polymerization (ATRP). After immersion of wafers presenting lines of these PMMA brushes in water and tetrahydrofuran, we observed mushroom-and brush-like regimes through grafting densities and surface coverages, respectively, for the PMMA brushes with various pattern resolutions. In the mushroom-like regime, the distance between lines of PMMA brushes was smaller than that of the lines patterned lithographically on the wafer; in the brush-like regime, this distance was approximately the same. This new strategy allows polymer brushes to be prepared through graft polymerization and then have their patterns varied through solvent immersion. (C) 2009 Elsevier Inc. All rights reserved.
Characterizing the polymeric status of Helicobacter pylori heat shock protein 60

Helicobacter pylori heat shock protein 60 (HpHsp60) was first identified as an adhesion molecule associated with H. pylori infection. Here we have analyzed the structure of HpHsp60 via amino acid BLAST, circular dichroism, and electrophoresis and the results indicate that most recombinant HpHsp60 molecules exist as dimers or tetramers, which is quite different from Escherichia coli Hsp60. Treatment of human monocytic cells THP-1 with HpHsp60 was found to up-regulate a panel of cytokines including IL-1 alpha, IL-8, IL-10, IFN-gamma, TNF-alpha, TGF-beta, GRO, and RANTES. Carboxymethylated HpHsp60 molecules with a switched oligomeric status were able to further enhance NF-kappa B-mediated IL-8 and TNF-alpha secretion in THP-1 cells compared to unmodified HpHsp60 molecules. These results indicated that the oligomeric status of HpHsp60s might have an important role in regulating host inflammation and thus help facilitate H. pylori persistent infection.
