In the discussion of lava dome formation, viscosity of magma plays an important role. Measurements of viscosity of magmas in field and laboratory are briefly summarized. The types of lava dome emplac...
We study the abelian sandpile growth model, where n particles are added at the origin on a stable background configuration in Zd. Any site with at least 2d particles then topples by sending one partic...
In ~ 50% of the ocean, iron (Fe) limits phytoplankton growth, including that of the diatom Pseudo-nitzschia. Fe-limited Pseudo-nitzschia spp. may produce the potent neurotoxin domoic acid (DA) to acce...
Negative trends in the monthly MODerate resolution Imaging Spectroradiometer (MODIS) Enhanced Vegetation Index (EVI) time-series were found to be widespread in natural (non-cropland) ecosystems of the...
In this paper, we consider the free boundary for the inho-mogeneous obstacle problem with zero obstacle. Werstly establish the growth rates for the solution u(x) and the gradient of u(x), awa...
Estimation of Growth Rates and Analysis of its Components in the Gezira Scheme。
We consider a heterogeneous agent-based economic model where economic agents have strictly bounded rationality and where income allocation strategies evolve through selective imitation. Income is cal...
We present upper and two-sided bounds of the exponential growth rate for a wide range of power-free languages. All bounds are obtained with the use of algorithms previously developed by the author.
When growth rates of series such as GDP are published by the Office for National Statistics, the contributions of individual components are also often reported. These contributions are a reflection of...
Firms exhibit a wide variability in growth rates. This can be seen as another manifestation of the fact that firms are different from one another in several respects. This study investigated this vari...
This paper presents an analysis of the differential growth rates of the farming and non-farming segments of a rural Scottish community during the 19th and early 20th centuries using the variable-r met...
Despite the fact that frequent aerosol formation has been observed in various locations in the atmosphere, the overall magnitude of the new particle formation as a particle source is still unclear. In...
The main objectives of this study are to examine the trends in area, production and yield of Iran’s agricultural production especially food grains; the decomposition of output growth of main crops and...
The relationship between the size and the variance of firm growth rates is known to follow an approximate power-law behavior (S) ∼ S− (S) where S is the firm size and (S) ≈ 0.2 is an e...
We consider a linear model of a topographically induced shear instability, described by Pedlosky (1980). The perturbation technique used by Pedlosky, to establish the existence of unstable normal mode...
