We introduce a dynamic noisy rational expectations model, in which information diffuses through a general network of agents. In equilibrium, agents’ trading behavior and profitability are determined by their position in the network. Agents who are more closely connected have more similar period-by-period trades, and an agent’s profitability is determined by how central the agent is, using a cen...

We present a tractable, static, general equilibrium model with multiple sectors in which firms offer workers incentive contracts and simultaneously raise capital in stock markets. Workers optimally invest in the stock market and at the same time hedge labor income risk. Firms rationally take agents’ portfolio decisions into account. In equilibrium, the cost of capital of each sector is endogeno...

AIMS Restenosis is an undesirable consequence following percutaneous vascular interventions. However, the current strategy for preventing restenosis is inadequate. The aim of this study was to investigate the role of low-voltage gated T-type calcium channels in regulating vascular smooth muscle cell (VSMC) proliferation during neointimal formation. METHODS AND RESULTS Wire injury of mice caro...

Calcium ion (Ca2+) is one of the key regulatory elements for ciliary movements in the Paramecium species. It has long been known that members of Paramecium species including green paramecia (Paramecium bursaria) exhibit galvanotaxis which is the directed movement of cells toward the anode by swimming induced in response to an applied voltage. However, our knowledge on the mode of Ca2+ action du...

An important aspect of Business to Business ECommerce is the agile Virtual Enterprise (VE). VEs are established when existing enterprises dynamically form temporary alliances, joining their business in order to share their costs, skills and resources in supporting certain activities. Currently, existing enterprises use workflows to automate their operation and integrate their information system...

Background: Behavioral variant frontotemporal dementia (bvFTD) patients show prefrontal cortex dysfunction and atrophy. Methods: We investigated whether executive function in conjunction with prefrontal cortex atrophy discriminates bvFTD and Alzheimer’s disease (AD) patients efficiently at presentation. Results: AD and bvFTD patients were distinguishable by 89.5% on their performance of 3 execu...

The evaluation of traditional IR systems is performed in an ideal situation, without workload in the IR system, however the Web IR systems are under different workload levels through the time. Therefore, the performance evaluation must be done considering several workload environments. For this purpose, we have designed and developed USim, a tool for the performance evaluation of Web IR systems...
