W e consider a supply chain with a supplier that sells to a retailer under a revenue-sharing arrangement. Demand is uncertain and unobservable to the supplier. We assume that the retailer is rational, that is, the retailer behaves opportunistically and underreports sales revenues to the supplier whenever such underreporting is profitable. Assuming the supplier has the ability to audit the retai...

The inclusion of a macroscopic adaptive threshold is studied for the retrieval dynamics of layered feedforward neural network models with synaptic noise. It is shown that if the threshold is chosen appropriately as a function of the cross-talk noise and of the activity of the stored patterns, adapting itself automatically in the course of the recall process, an autonomous functioning of the net...

The inclusion of a macroscopic adaptive threshold is studied for the retrieval dynamics of both layered feedforward and fully connected neural network models with synaptic noise. These two types of architectures require a different method to be solved numerically. In both cases it is shown that, if the threshold is chosen appropriately as a function of the cross-talk noise and of the activity o...

The characterization of genetic aberrations in paraffin-embedded tumor material is impaired by contaminating normal cells. In the present study on the genetic causes of loss of HLA expression in diffuse large B-cell lymphoma (DLBCL), we compared the efficacy of microdissection with flow cytometric sorting of tumor cells. Single-cell suspensions from paraffin-embedded material of 5 DLBCL cases w...

This paper investigates how the performance of a preventive control scheme using a Leaky Bucket can be improved by using a feedback control loop. The proposed scheme is adaptive to congestion within the network. The queue occupancy of a network element is used as an indication of congestion and the individual sources, whose transmission path passes through the congested switch, are informed to ...

This paper provides empirical study on the behavior of the Shanghai and the Shenzhen stock exchanges after the Chinese government announced to increase the securities transaction tax from 0.3% to 0.5% in May 9, 1997. We examine the impact of the increased transaction tax on the volatility of stock returns and tax revenue. We find that the return volatility significantly increased. We also find ...

In Local Area Networks (LAN) connected together by bridges, flow control and smooth traffic in the network is very important. However, congestion at bridges can cause intensive loss of received frames. In addition, the received frames are thrown away and have to be retransmitted by the source station, which causes more congestion and massive reduction in the overall network throughput. The netw...
