A novel HfO<sub>2</sub>-based resistive memory with the TiN electrodes is proposed and fully integrated with 0.18 mum CMOS technology. By using a thin Ti layer as the reactive buffer layer into the anodic side of capacitor-like memory cell, excellent memory performances, such as low operation current (down to 25 muA), high on/off resistance ratio (above(More)
Multiple, bilateral renal carcinomas are a frequent occurrence in von Hippel–Lindau (VHL) disease. To elucidate the aetiological role of the VHL gene in human kidney tumorigenesis, localized and advanced tumours from 110 patients with sporadic renal carcinoma were analysed for VHL mutations and loss of heterozygosity (LOH). VHL mutations were identified in(More)
Kernel hardness that is conditioned by puroindoline genes has a profound effect on milling, baking and end-use quality of bread wheat. In this study, 219 landraces and 166 historical cultivars from China and 12 introduced wheats were investigated for their kernel hardness and puroindoline alleles, using molecular and biochemical markers. The results(More)
In the course of Cu/low-k technology development and qualification, low-k time-dependent dielectric breakdown (TDDB) is rapidly becoming one of the most important reliability issues. In order to accurately predict low-k TDDB reliability, it is crucial to clarify the electric field dependence and temperature dependence of time-to-breakdown. In this study,(More)
The memory performance of hafnium oxide (HfO<sub>x</sub>)-based resistive memory containing a thin reactive Ti buffer layer can be greatly improved. Due to the excellent ability of Ti to absorb oxygen atoms from the HfO<sub>x</sub> film after post-metal annealing, a large amount of oxygen vacancies are left in the HfO<sub>x</sub> layer of the(More)
Flowers were formed from shoot tips of bitter melon (Momordica charantia L.) cultured on Murashige and Skoog medium supplemented with 90 mM sucrose, 0.05 mM Fe2+ and 4 µM N6-benzyladenine (BA). The addition of 0.05 mM Fe2+ to the medium prevented chlorosis of the explant and promoted normal flowering. Increasing the ratio of carbon to nitrogen promoted male(More)
Immunocytochemical localization of polygalacturonic acid (pectin) and methyl-esterified pectin in the walls of pollen tubes of 20 species of flowering plants grown in vitro was investigated by using monoclonal antibodies (MAbs) JIM5 and JIM7 and by means of confocal laser scanning microscopy (CLSM). In general, periodic annular deposits of pectins were(More)
The study of low-k TDDB line space scaling is important for assuring robust reliability for new technologies. Although spacing effects due to line edge roughness (LER) on low-k TDDB lifetime were reported previously (Chen et al., 2007; Lloyd et al., 2007; Kim et al., 2007), there has been a lack of an analytical model with which to link line edge roughness(More)
BACKGROUND Cdc42 and other Rho GTPases are conserved from yeast to humans and are thought to regulate multiple cellular functions by inducing coordinated changes in actin reorganization and by activating signaling pathways leading to specific gene expression. Direct evidence implicating upstream signals and components that regulate Cdc42 activity or for(More)
Transcription factors of the DREBP subgroup and the EREBP subgroup contain conserved DNA-binding domains called AP2/EREBP domains, which specifically bind to DRE cis-element and GCC-box, respectively. The 14th and 19th amino acid residues of AP2/EREBP domains are absolutely conserved in the transcription factors of the DREBP subgroup as well as in the EREBP(More)
