<B>SUMMARY</B><P>Extended-spectrum <I>β</I>-lactamase (ESBL) production has been very rare in serotype K1 <I>Klebsiella pneumoniae</I> ST23 strains, which are well-known invasive community strains. Among 92 ESBL-producing strains identified in 218 isolates from nine Asian countries, serotype K1 <I>K. pneumoniae</I> strains were screened. Two ESBL-producing <I>K. pneumoniae</I> isolates from Singapore and Indonesia were determined to be serotype K1 and ST23. Their plasmids, which contain CTX-M-15 genes, are transferable rendering the effective transfer of ESBL resistance plasmids to other organisms.</P>

IκBα is a member of IκB family, which sequesters NF-κB in an inactivate form in the cytoplasm and blocks the translocation of NF-κB to nucleus. The IκBα paralogs of rock bream (OfIκBα-A and OfIκBα-B) encoded IκBα proteins with typical features including, highly conserved IκB degradation motif, six ankyrin repeats and a PEST sequence. However, their amino acid identity and similarity were only 55.6 and 69.7%, respectively suggesting that these two genes could be the two different isoforms of IκBα. The number and size of the exons of OfIκBα-A and OfIκBα-B were conserved well with all the compared vertebrate species, although they have significantly different genomic sizes. Phylogenetic analysis revealed that OfIκBα-A and OfIκBα-B proteins cluster with IκBα family members; however, they were grouped with different subclades in IκBα family. Tissue specific expression of OfIκBα mRNA was constitutively detected in all the tested tissues, and they showed the higher transcription level in heart, liver, gill and peripheral blood cells, respectively. The injection of flagellin stimulated the mRNA expression of OfIκBα paralogs in head kidney and intestine. Moreover, the OfIκBα mRNA expression in gill and liver was significantly up-regulated by LPS, poly I:C and Edwardsiella tarda challenges. The transcription of OfIκBα was up-regulated in early-phase of injection and then rapidly restored. These results suggest that the OfIκBα paralogs might be involved in rapid immune responsive reactions in rock bream against bacterial and viral pathogens.

A rapid and accurate diagnosis of brucellosis is required to reduce and prevent the spread of disease among animals and the risk of transfer to humans. In this study, a Brucella abortus-specific (Ba) LAMP assay was developed, that had six primers designed from the BruAb2_0168 region of chromosome I. The specificity of this LAMP assay was confirmed with Brucella reference strains, B. abortus vaccine strains, B. abortus isolates and phylogenetically or serologically related strains. The detection limit of target DNA was up to 20fg/μl within 60min. The sensitivity of the new LAMP assay was equal to or slightly higher than other PCR based assays. Moreover, this Ba-LAMP assay could specifically amplify all B. abortus biovars compared to previous PCR assays. To our knowledge, this is the first report of specific detection of B. abortus using a LAMP assay. The Ba-LAMP assay can offer a rapid, sensitive and accurate diagnosis of bovine brucellosis in the field.

In the present study we carried out a dynamic analysis of a CNT-based mass sensor by using a finite element method (FEM)-based nonlinear analysis model of the CNT resonator to elucidate the combined effects of thermal effects and nonlinear oscillation behavior upon the overall mass detection sensitivity. Mass sensors using carbon nanotube (CNT) resonators provide very high sensing performance. Because CNT-based resonators can have high aspect ratios, they can easily exhibit nonlinear oscillation behavior due to large displacements. Also, CNT-based devices may experience high temperatures during their manufacture and operation. These geometrical nonlinearities and temperature changes affect the sensing performance of CNT-based mass sensors. However, it is very hard to find previous literature addressing the detection sensitivity of CNT-based mass sensors including considerations of both these nonlinear behaviors and thermal effects. We modeled the nonlinear equation of motion by using the von Karman nonlinear strain-displacement relation, taking into account the additional axial force associated with the thermal effect. The FEM was employed to solve the nonlinear equation of motion because it can effortlessly handle the more complex geometries and boundary conditions. A doubly clamped CNT resonator actuated by distributed electrostatic force was the configuration subjected to the numerical experiments. Thermal effects upon the fundamental resonance behavior and the shift of resonance frequency due to attached mass, i.e., the mass detection sensitivity, were examined in environments of both high and low (or room) temperature. The fundamental resonance frequency increased with decreasing temperature in the high temperature environment, and increased with increasing temperature in the low temperature environment. The magnitude of the shift in resonance frequency caused by an attached mass represents the sensing performance of a mass sensor, i.e., its mass detection sensitivity, and it can be seen that this shift is affected by the temperature change and the amount of electrostatic force. The thermal effects on the mass detection sensitivity are intensified in the linear oscillation regime and increase with increasing CNT length; this intensification can either improve or worsen the detection sensitivity.

As the growth of injection molding technology, injected-molded optical products require higher dimension accuracy and optical stability than ever. In the present study, four kinds of molding mechanisms, i.e., conventional injection molding(CIM), injection/compression molding(ICM), rapid heat and cooling the mold(RHCM) and rapid injection/compression molding(RICM) were chosen to investigate the optical anisotropy of 7 inch LGP by examining the in-plane and gap-wise distribution of birefringence and extinction angle. As a result, the compression process could decrease flow-induced birefringence for the whole region and rapid heating could decrease the birefringence level than conventional molding mechanism. Finally, for the combination of compression and rapid heating, the reversal flow was detected from the distribution of extinction angle near the gate.

<P>ABSTRACT</P><P>We present a 1.1 mm wavelength imaging survey covering 0.3 deg<SUP>2</SUP> in the COSMOS field. These data, obtained with the AzTEC continuum camera on the James Clerk Maxwell Telescope, were centred on a prominent large-scale structure overdensity which includes a rich X-ray cluster at <I>z</I>≈ 0.73. A total of 50 mm-galaxy candidates, with a significance ranging from 3.5 to 8.5σ, are extracted from the central 0.15 deg<SUP>2</SUP> area which has a uniform sensitivity of ∼1.3 mJy beam<SUP>−1</SUP>. 16 sources are detected with S/N ≥ 4.5, where the expected false-detection rate is zero, of which a surprisingly large number (9) have intrinsic (deboosted) fluxes ≥5 mJy at 1.1 mm. Assuming the emission is dominated by radiation from dust, heated by a massive population of young, optically obscured stars, then these bright AzTEC sources have far-infrared luminosities >6 × 10<SUP>12</SUP> L<SUB>⊙</SUB> and star formation rates >1100 M<SUB>⊙</SUB> yr<SUP>−1</SUP>. Two of these nine bright AzTEC sources are found towards the extreme peripheral region of the X-ray cluster, whilst the remainder are distributed across the larger scale overdensity. We describe the AzTEC data reduction pipeline, the source-extraction algorithm, and the characterization of the source catalogue, including the completeness, flux deboosting correction, false-detection rate and the source positional uncertainty, through an extensive set of Monte Carlo simulations. We conclude with a preliminary comparison, via a stacked analysis, of the overlapping MIPS 24-μm data and radio data with this AzTEC map of the COSMOS field.</P>

本 硏究에서는 Iodine을 dope시켜 Bridgman法으로 成長시킨 n-type CdTe를 admittance分光法을 이용하여 溫度變化에 따른 capacitance와 donductance를 測定하였다. capacitance와 conductance는 溫度增加에 따라 一般的으로 增加하나, 250K 근처에서 capacitance는 급격한 增加를 보이고 conductance는 極大値를 보인다. 이 conductance의 極大値 測定 周波數를 增加시키면 높은 溫度쪽으로 shift하는 것을 볼 수 있었고, 이것으로부터 구한 trap에너지準位, 電子放出率, trap濃度는 각각 E-0.42eV 2.14×10sec, 6.57×10cm이었다. Measurememts of the capacitance and the conductance as a function of tmeperature of I-doped n-type CdTe grown by the Bridgman method has been performed by means of the admittance spectroscopy. It is found that the capacitance and the conductance normally show trend of increase with temperature and the increase of the capacitance shows rapid change near 250K, whereas the conductance shows a peak there. This peak of the conductance shows shift toward the higher temperature with the measured frequency. The trap energy level, the electron emission rate and the trap concentration obtained from the set of these results are E-0.42eV 2.14×10sec, 6.57×10cm respectively.
