PMID: 18315117
Rev Sci Instrum. 2008 Feb;79(2):02A327. doi: 10.1063/1.2801683.

For RIKEN radio isotope beam project, we started to construct the new superconducting electron cyclotron resonance ion source (SC-ECRIS), which has an operational frequency of 28 GHz, in 2007. The main feature of this ion source is that we...

Measurement of plasma potential of liquid-He-free superconducting electron cyclotron resonance ion source.

The Review of scientific instruments

Higashijima H, Takai W, Nakagawa T, Higurashi Y, Kidera M, Goto A.
PMID: 18315190
Rev Sci Instrum. 2008 Feb;79(2):02B505. doi: 10.1063/1.2821505.

The plasma potential of liquid-He-free superconducting electron cyclotron resonance ion source was measured as a function of minimum strength of mirror magnetic field (B(min)) and gas pressure with the method based on the retarding electric field. We observed that...

Retrieval of snow physical parameters using a ground-based spectral radiometer.

Applied optics

Kuchiki K, Aoki T, Tanikawa T, Kodama Y.
PMID: 19823241
Appl Opt. 2009 Oct 10;48(29):5567-82. doi: 10.1364/AO.48.005567.

A ground-based spectral radiometer system for albedo and flux (GSAF) was developed to retrieve a mass concentration of snow impurities and effective snow grain size automatically. The GSAF measures spectral albedo and diffuse fraction with a single sensor to...

Transition from transparent aerogels to hierarchically porous monoliths in polymethylsilsesquioxane sol-gel system.

Journal of colloid and interface science

Kanamori K, Kodera Y, Hayase G, Nakanishi K, Hanada T.
PMID: 21377166
J Colloid Interface Sci. 2011 May 15;357(2):336-44. doi: 10.1016/j.jcis.2011.02.027. Epub 2011 Feb 15.

A transition from hierarchical pore structures (macro- and meso-pores) to uniform mesopores in monolithic polymethylsilsesquioxane (PMSQ, CH(3)SiO(1.5)) gels has been investigated using a sol-gel system containing surfactant Pluronic F127. The precursor methyltrimethoxysilane (MTMS) undergoes an acid/base two-step reaction, in...

Electrodialytic ion isolation for matrix removal.

Analytical chemistry

Ohira S, Kuhara K, Kudo M, Kodama Y, Dasgupta PK, Toda K.
PMID: 22642426
Anal Chem. 2012 Jun 19;84(12):5421-6. doi: 10.1021/ac300982k. Epub 2012 Jun 07.

We report a fully automated online sample pretreatment system for ionic analytes that extracts the ionic analytes from the sample and largely removes the nonionic sample matrix and can preconcentrate the analyte. Sample pretreatment is a key analytical process;...

Feasibility of fused imaging for the evaluation of radiofrequency ablative margin for hepatocellular carcinoma.

AIM: To evaluate the feasibility of fusion of conventional imaging modalities to facilitate assessment of ablative margin of radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC).METHODS: Two hundred and thirty-nine liver lesions in 109 patients underwent percutaneous RFA under ultrasound...

A similarity measure between patterns with nonindependent attributes.

IEEE transactions on pattern analysis and machine intelligence

Ito T, Kodama Y, Toyoda J.
PMID: 21869174
IEEE Trans Pattern Anal Mach Intell. 1984 Jan;6(1):111-5. doi: 10.1109/tpami.1984.4767484.

A generalized version of a set-theoretical measure for obtaining similarities between patterns with nonindependent attributes is presented. The dependence here is given by the pairwise correlation. Since the proposed measure needs no assumption of attribute independence, the resulting similarity...

We investigate the light-harvesting property of a π-conjugated dendrimer, phenylene-based dendrimer (phDG2), by carrying out a semi-classical Ehrenfest dynamics simulation based on the time-dependent density functional theory. Similar to our previous study of star-shaped stilbenoid phthalocyanine (SSS1Pc), phDG2 shows...
