Let X = Xkk [greater-or-equal, slanted] 1 be an i.i.d. random sequence and Y =Ykk [greater-or-equal, slanted] 1 be an independent random sequence which is also independent of X. We suppose X and Y take values in the sequence space , where S is either , the space of non-negative integers, or +,...

Many specialists in international trade have started saying that the era of a mega FTA is approaching. If the three poles of the global economy, namely East Asia, EU and the United States, form mega FTAs, most of the volume of global trade will be covered. That may be fine, but there will be...

The paper studies the convergence of the cluster-variation method to the rigorous result as the cluster size increases. The calculation is done on the phase boundary at T = 0 between the A2B-type ordered phase and the disordered phase on a two-dimensional triangular lattice with nearest-neighbor...

Behaviors of the generalized random walks (GRW) are directly studied by using computer. The GRW have a non-linear term yielding a non-Markovian character. The non-Markovian character represents memory effects in the processes through the jumping probabilities P̃αN(m|m−α1) between sites...

This paper discusses data used in publishing statistics on earnings, the distribution of household income and poverty in China by the National Bureau of Statistics (NBS) which is widely used by policy makers, international agencies and researchers. Unlike many other countries, China until...
