The stop closure durations and voice onset time of geminate and single voiceless stops in Japanese were examined with two groups of subjects: native Japanese and fluent Americans. The two groups were found to have different manners of timing control of these segments. The results indicated that the 10 native speakers distinguished between the geminate and(More)
We describe the use of gold nanoparticle-oligonucleotide complexes as intracellular gene regulation agents for the control of protein expression in cells. These oligonucleotide-modified nanoparticles have affinity constants for complementary nucleic acids that are higher than their unmodified oligonucleotide counterparts, are less susceptible to degradation(More)
Nucleic acids act as the carriers of genetic information, and most organisms contain a type of enzymes called endonu-cleases, [1] which can hydrolyze the phosphodiester linkages in the nucleic acid backbone. These nucleases are important for many processes involving the replication, repair, and recom-bination of nucleic acids. Endonucleases such as DNA(More)
A hydrogen peroxide (H2O2) sensor based on Pd nanoparticles (NPs) and glassy carbon electrodes (GCEs) is fabricated. Pd NPs are deposited on GCEs by using a gas phase cluster beam deposition technique. The NP-deposited electrodes show enhanced electrocatalytic activity in reduction of H2O2. The electrode with an optimized NP coverage of 85 % has a high(More)
Background: Basilar artery occlusion (BAO) usually develops with brainstem symptoms, but rarely seizure. We report two cases of BAO presenting with unconsciousness and seizure. Case Report: Two male patient were visited to emergency room with unconscious-ness and seizure (tonic extension and generalized tonic clonic seizure) immediately after arrival. BAO(More)
A new method for determining the vitrification rate of pottery depending on the firing temperature was devised using secondary electron images (SEI) of scanning electron microscope (SEM). Several tests were performed to establish the appropriate operating conditions of SEM and reproducibility as well as to examine the applicability of the method. The(More)
The effect of a sacrificial layer residue on a cantilever beam in the nano-electro-mechanical nonvolatile memory is investigated for the optimization of reliability characteristics. Different from previous research, pull in voltage model of nano-electro-mechanical nonvolatile memory used triangular residue layer which is considered by real wet etching(More)
The structure, electronic, magnetic properties of Si(n)Mn clusters up to n=15 are systematically investigated using the density functional theory within the generalized gradient approximation. In the most stable configurations of Si(n)Mn clusters, the equilibrium site of Mn atom gradually moves from convex, to a surface, and to a concave site as the number(More)
