Paddystem borer (Scirpophaga incertulas) is a serious rice pest. The damaged plants wither into dead tassel or white tassel. Such damage leads to decreased in rice production. In order to control the damages of paddystem borer efficiency, it is very important to analyze and study the regulation of population dynamics and the related factors affecting the development. This investigated the popul...

Abstract To conduct baseline load forecasting for commercial building users participating in demand response, this paper proposes a response method that takes meteorological factors into account. Using the principal component analysis, indicators contributing more than 80% to are selected as reference data neural network load. The isolated forest algorithm and KNN used identify abnormal fill mi...

Although treeline elevations are limited globally by growing season temperature, at regional scales treelines frequently deviate below their climatic limit. The cause of these deviations relate to a host of climatic, disturbance, and geomorphic factors that operate at multiple scales. The ability to disentangle the relative effects of these factors is currently hampered by the lack of reliable ...
