Nitrogen is a dominant regulator of vegetation dynamics, net primary production, and terrestrial carbon cycles; however, most ecosystem models use a rather simplistic relationship between leaf nitrogen content and photosynthetic capacity. Such an approach does not consider how patterns of nitrogen allocation may change with differences in light intensity,(More)
Photosynthetic capacity, determined by light harvesting and carboxylation reactions, is a key plant trait that determines the rate of photosynthesis; however, in Earth System Models (ESMs) at a reference temperature, it is either a fixed value for a given plant functional type or derived from a linear function of leaf nitrogen content. In this study, we(More)
Landscape attributes that vary with microtopography, such as active layer thickness (ALT), are labor intensive and difficult to document effectively through in situ methods at kilometer spatial extents, thus rendering remotely sensed methods desirable. Spatially explicit estimates of ALT can provide critically needed data for parameterization,(More)
Using Finite element methods, a model to predict the Cu pumping in Through Silicon Vias (TSV) is built. The processes which a TSV undergoes after Cu electroplating are considered and the model is built in such a way that after each process sequence, the stress and strain data are transferred into the following sequence and used as input conditions. The(More)
Process simulations provide vital insights to identify the key process steps to dedicate wafer resources for improvement or to determine investment on tool capability. We considered this problem in the context of an industry-like 5nm Back-End-of-Line flow being developed in IMEC and modeled the approximately 150 step process flow in COVENTOR(More)
We present a semi-automated approach to recognize and hierarchically partition water-body regions of Arctic tundra landscape, such as streams, inundated drained thaw lake basins and ice wedge polygon ponds, in high resolution satellite imagery. The approach integrates the active contours without edges (ACWE) technique and shape-based recognition, and(More)
