The genotype of the hepatitis C virus (HCV) strain infecting a given patient is an important predictive factor for the clinical outcome of chronic liver disease and its response to anti-viral therapeutic agents. We herein sought to develop a new easy, sensitive and accurate HCV genotyping method using annealing genotype- specific capture probes (AGSCP) in an automation-friendly 96-well plate format. The validation of our new AGSCP was performed using the Standard HCV Genotype Panel. We then used both our AGSCP and the commercially available INNO-LiPA assay to analyze the HCV genotypes from 111 Korean patients. Discordant results were analyzed by direct sequencing. AGSCP successfully genotyped the standard panel. The genotypes of 111 patient samples were also obtained successfully by AGSCP and INNO-LiPA. We observed a high concordance rate (93 matched samples, 83.8%) between the two assays. Sequencing analysis of the 18 discordant results revealed that the AGSCP had correctly identified 12 samples, whereas the INNO- LiPA had correctly identified only 6. These results collectively indicate that AGSCP assay is a convenient and sensitive method for large-scale genotyping, and it may be a promising tool for the determination of HCV and other genotypes in clinical settings.

<P>The effective work function (eWF) of Al-doped titanium carbide (TiAlC) metal electrodes prepared by atomic layer deposition shows a strong dependence on the underlying gate dielectrics. The eWF of TiAlC on HfO2 shows a low value of 4.2 eV independent of the deposition temperature and process conditions, whereas that on SiO2 shifted to a midgap value of 4.7 eV, and it was sensitive to the process conditions. The mechanism underlying this TiAlC work function dependence on different gate dielectrics is investigated in detail.</P>

The fuel economy estimates essentially serve two purposes: to provide consumers with a basis on which to compare the fuel economy of different vehicles, and to provide consumers with a reasonable estimate of the range of fuel economy they can expect to achieve. The current fuel economy label values utilize measured fuel economy over city (CVS-75 mode) driving cycles. However, this test driving mode can not be evaluated the variety factor of the real-world. These factors include differences between the way vehicles are driven on the road and over the test cycles, air conditioning use, widely varying ambient temperature and humidity, widely varying trip lengths, wind, precipitation, rough road conditions, hills, etc. The purpose of the new test method for fuel economy is to better account for three of these factors : 1) on-road driving patterns (i.e. higher speeds and more aggressive driving (higher acceleration rates)), 2) air conditioning, and 3) colder temperatures. The new test methods will bring into the fuel economy estimates the test results from the five emissions tests in place today : CVS-75, HWFET, US06, SC03 and Cold CVS-75. Based on these new test methods, this paper discusses the characteristics of test method on Hybrid electric vehicle (HEV). And this paper assesses the fuel economy label of HEV.

<P>Erbium carbide (ErC<SUB>2</SUB>) prepared by atomic layer deposition (ALD) is successfully demonstrated for the first time as a novel work function (WF) metal for nMOSFET applications. The prepared ErC<SUB>2</SUB> shows a very low effective WF (eWF), as low as 3.9 eV on HfO<SUB>2</SUB>, yet with excellent thermal stability. In addition, it did not show significant Fermi-level pinning on high-k dielectrics even after high-temperature annealing. The low eWF property of ErC<SUB>2</SUB> originates from the properties of the lanthanide family, while its good thermal stability is attributed to the properties of metal carbides. ALD-ErC<SUB>2</SUB> has superior conformality over other deposition methods, and thus is a strong candidate for 3-D structure devices.</P>
