Recently, it has been shown that the zero-energy eigenstate – corresponding to the stationary state – of a stochastic Hamiltonian with nearest-neighbour interaction in the bulk and single-site boundary terms, can generically be written in the form of a so-called matrix-product state. We...

We consider a single server system consisting of e queues with different types of customers (Poisson streams) andk permanent customers. The permanent customers and those at the head of the queues are served in processor-sharing by the service facility (head-of-the-line processor-sharing). The...

The nature of correlated electrons confined in two dimensions is analyzed using the spectral statistics of three electrons confined in a square-well quantum dot. When in a small quantum dot, the spectral statistics of electrons are similar to those of Poisson distribution. As the quantum dot...

Should we judge empirical generalisations as mere regularities, separately from theory? The paper argues that this may bring out the links with theory better and gives illustrative examples. It also notes how in pursuing empirical generalisability more explicitly, we will have to shift how we...

We have had a spate of works on "Japanese Management" in the world, but very few on "Japanese Accounting". In this article it is made clear that the functioning of accounting is contingent on the culture in which the accounting systems are incorporated, and that in order to discuss this...
