We developed, for the first time, the manipulation system based on optoelectronic tweezers (OET) which manipulates multiple nano/micro components on an arbitrary substrate with concurrent observation of the component motion. From the theoretical analysis, the manipulation force of a hundred pN order is expected to act on components. It was successfully(More)
We are grateful to Masaya Sakuragawa, Kotaro Tsuru, two anonymous referees, seminar participants at Sophia University and the International Monetary Fund, and many staff members at the Bank of Japan for their helpful comments on an earlier draft. The paper has benefited from the excellent research assistance of Hiroki Yoshino. Tomoki Tanemura kindly(More)
After the collapse of the asset price bubble, Japanese banks are said to have been reluctant to write off bad loans, even in cases where there is little prospect of borrower firms being able to repay the loans extended. This phenomenon is known as forbearance lending. We illustrate this using a simple model in which a bank is shown to have an incentive to(More)
In this paper, we construct a simple measure of sectoral credit shifts, defined as the dispersion of growth rates of bank loans across sectors, and investigate what effects they had on Japan’s economy and what accounted for their development. We find that (i) during the 1990s, the amount of sectoral credit shifts declined significantly, which was(More)
The effects of thyroxine and 5 alpha-dihydrotestosterone on the activities of various marker enzymes in the submandibular glands of immature mice were studied. The responsiveness to thyroid hormone appeared at latest by day five after birth, which was ten d earlier than the appearance of androgen responsiveness. The activity of trypsin-like esteroprotease,(More)
Systematic experiments of DNA mediated sequential and selective self-assembly of 5 × 5 (μm2) silicon micro-components to a substrate using DNA-grafted-polymers as flexible binding spacers were carried out for the first time. The surfaces of the micro-components and sites on the substrate were modified by the same 30-mers single-stranded-DNA(More)
A novel sequential self-assembly process of nano/micro components applying deoxyribonucleic acid (DNA) hybridization was proposed for the first time and its validity was experimentally verified. In the proposed process, characteristics of DNA, such as hybridization specificity of complementary pairs of single-stranded DNA (ssDNA) into a double-stranded DNA(More)
Changes of alpha-amylase activity (1,4-alpha-D-glucan glucanohydrolase, EC 3.2.1.1) in mouse parotid gland and pancreas were investigated during embryonic and postnatal development. Amylase activity in the parotid gland increased from around day 12 and reached the adult level on day 30. On the other hand, the activity in the pancreas increased during the(More)
We demonstrated a new approach utilizing contact potential difference (CPD) based self-assembly for a future sequential assembly of nano/micro components and face alignment of submillimeter scale components. Two types of experiments realized by CPD were carried out; 1) sequential assembly of silica particles using Coulomb force induced by contacting a(More)
