Late Pliocene–Pleistocene fossil diatom assemblages from Ocean Drilling Program (ODP) Leg 145 Hole 884B in the western subarctic Pacific were investigated to improve the diatom biostratigraphy. Moreover, the paleoceanographic records at Hole 884B were compared with those in Integrated Ocean Drilling Program (IODP) Expedition 323 Holes U1341B and U1343E in the Bering Sea for the time interval of 2...
Integrated Ocean Drilling Program (IODP) Expedition 323 was dedicated to reconstruct the details of the Pliocene–Pleistocene paleoenvironmental conditions of the Bering Sea. In this study, fossil diatom assemblages from Hole U1343E were investigated to define diatom biostratigraphy and reveal paleoceanography of the Bering slope region throughout Pleistocene. As the results, four diatom zones with...
Results of another molecular design of the negative-tone molecular resist for improvement of sensitivity were discussed. Frictional force spectroscopy (FFS) was performed for investigating thermal property of resist films by a scanning probe microscope (SPM) with sweeping temperature. Depth profile of the resist components was measured by TOF-SIMS with gradient shaving preparation. EB lithographic...
In this study, the effect of fluorine atoms on acid generation upon EUV exposure using an acid sensitive dye is investigated. Fluorinated polymers is used as polymers. Triphenylsulfonium-triflate (TPS-tf) is used as an acid generator. Coumarin6 (C6, Aldrich Chem.) is used as an indicator to evaluate acid yields. Tetrahydrofuran (THF, Wako) is used as a casting solvent. It is experimentally confirmed...
The depth profile of acid generator distribution is investigated using X-ray reflectivity measurement at Spring-8. The depth profile in tBu-PHS thin resist films is made clear.
We, for the first time, analyzed the binding motifs of immunoglobulin G (IgG) in the cerebrospinal fluid (CSF) of human T lymphotropic virus type I (HTLV-I)-associated myelopathy/tropical spastic paraparesis (HAM/TSP) patients with a phage library displaying 12-mer random peptides. As a result, the sequences highly homologous to HTLV-I gp46 192-199, 237-243 and 255-261 were the common linear epitopes...
