A 50-yr precedent was reversed in 1995 when, following a powerful windstorm, salvage logging was disallowed in the protected Adirondack Park State Forest Preserve of New York, United States. Damage from a similar windstorm in 1950 had provoked massive salvage operations, approved by the New York State legislature on the grounds of fire prevention and resource conservation. Following the 1995 st...
Are we making the best use of laboratory computer systems? In this first issue of the 1983 volume of the Journal of Automatic Chemistry we can look back on a very successful first year with our new publisher, Taylor & Francis Ltd. Their experience in scientific publishing has been of considerable value to me and the editorial team. We now have a well-produced, accepted and well-presented produc...
Dr. Jung-Gi Im served for five years as the Editor-inchief. As a member of the Board of Directors of the Korean Radiological Society back in the last decade, Dr. Im devoted himself to giving birth to this English journal. In the editorial of the inaugural issue in 2000, Dr. Im pronounced that his editorial policy was to meet global standards and trends in radiology combined with an EastAsian pe...
We consider the problem (J, F) of allocating a single machine to the stochastic tasks in J in such a way that precedence constraints F are respected. If we have rewards which are discounted and additive then the problem of determining an optimal policy for scheduling in the class of fully preemptive policies can be formulated as a discounted Markov decision process (MDP). Policies are developed...
The precise and accurate quantitative evaluation of the temporal and spatial pattern of carbon (C) storage in forest ecosystems is critical for understanding the role of forests in the global terrestrial C cycle and is essential for formulating forest management policies to combat climate change. In this study, we examined the C dynamics of forest ecosystems in Shaanxi, northwest China, based o...
Tropical forests harbor a significant portion of global biodiversity and are a critical component of the climate system. Reducing deforestation and forest degradation contributes to global climate-change mitigation efforts, yet emissions and removals from forest dynamics are still poorly quantified. We reviewed the main challenges to estimate changes in carbon stocks and biodiversity due to deg...
