The standard analysis of firm-specific hu-man capital argues that the cost of and the return
to the investment will be shared by the worker and the employer. By sharing the investment, …

As acidic monomers of self-etching adhesives are incorporated into dental adhesives at
high concentrations, the adhesive becomes more hydrophilic. Water sorption by polymers …

A long-term employment relationship in Japan has been cited often as a principal reason for
Japan's high labor productivity. Yet, recent discussions suggest that Japan may not be …

We present an adaptive technique for compensating manufacturing and environmental
variability in subthreshold circuits using “canary flip-flop (FF),” which can predict timing errors. A …

Deep Neural Network has proved its potential in various perception tasks and hence become
an appealing option for interpretation and data processing in security sensitive systems. …

Besides micro-mechanical interlocking through hybrid-layer formation, self-etch adhesives
may benefit from additional chemical interaction between the functional monomer and …

Our knowledge of the mechanisms responsible for the degradation of resin–dentin bonds
are poorly understood. This study investigated the degradation of resin–dentin bonds after 1 …

The purpose of this study was to evaluate the degradation of resin–dentin bonds after 1
year of water storage. Resin–dentin‐bonded specimens were prepared with the use of an …

The prevalence in Japan of flexible wages in the form of bonus payments is explained by a
high profitability of investment in specific human capital together with the low costs of …

Recently several long‐term studies have reported evidence of the hydrolytic degradation of
collagen fibrils based on fractured surface observations after bond testing. Those studies …
