The water balance of inland lakes on the Tibetan Plateau (TP) involves complex hydrological processes; their dynamics over recent decades is a good indicator of changes in water cycle under rapid global warming. Based on satellite images and extensive field investigations, we demonstrate that a...

Finding out statistically significant words in DNA and protein sequences forms the basis for many genetic studies. By applying the maximal entropy principle, we give one systematic way to study the nonrandom occurrence of words in DNA or protein sequences. Through comparison with experimental...

To investigate whether diversification within a supply chain can help middlemen firms survive prolonged financial crises, we simulated an extension of the dynamical supply chain network model by Mizgier et al. (2012) under normal and crisis economic conditions. In these simulations, firms in the...

The non-point source pollution arising from soil erosion is one of the main reasons for the deterioration of the water quality of the Taihu Lake Basin. Forest plays an important role in controlling soil erosion and reducing nutrient loss. Based on the survey data on forest resources in Anji...

Given a sequence composed of a limited number of characters, we try to “read” it as a “text”. This involves segmenting the sequence into “words”. The difficulty is to distinguish good segmentation from enormous numbers of random ones. Aiming at revealing the nonrandomness of the...

We propose and analyze a random graph model which explains a phenomena in the economic company network in which company may not expand its business at some time due to the limiting of money and capacity. The random graph process is defined as follows: at any time-step t, (i) with probability...

An improved modal strain energy method is proposed for damage localisation in jacket-type offshore wind turbines by defining a series of stiffness-correction factors that can be employed to calculate the modal strain energy (MSE) of the measured model without utilising the stiffness matrix of...
