In inter-subject registration, one often lacks a good model of the transformation variability to choose the optimal regularization. Some works attempt to model the variability in a statistical way, but the re-introduction in a registration algorithm is not easy. In [1], we interpreted the elastic energy as the distance of the Green-St Venant strain tensor to the identity. By changing the Euclid...

Abstract We develop in this paper a novel intrinsic classification algorithm—multi-frequency class averaging (MFCA)—for classifying noisy projection images obtained from three-dimensional cryo-electron microscopy by the similarity among their viewing directions. This new algorithm leverages multiple irreducible representations of unitary group to introduce additional redundancy into representat...

The pursuit of sustainable resource use by manufacturing companies is driven by resource scarcity, environmental awareness, and cost savings potentials. To address these issues, Material Flow Cost Accounting (MFCA) has been developed and applied as an effective environmental management tool. Within MFCA’s general allocation, the accounts of products and losses are overrated by weight or volume....

To develop sustainable cropping systems, the coherence between economic, environmental, and energy aspects must be considered. We aimed to assess sustainability of corn (Zea mays) production using four tillage systems which varied in intensity soil disturbance (i.e., conventional till with moldboard plow (MP), chisel (CP), strip-tillage (ST), no-till (NT)) by performing life cycle assessment (L...

With the development trend and technological progress of lithium batteries, battery market is booming. This means that demand for batteries has increased significantly, resulting in a large number discarded batteries. The consumption plenty may lead to scarcity expending relevant raw material metal resources, as well serious heavy environmental pollution. Therefore, it great significance recycl...

Blood vessel extraction is an important step for abnormality detection and for obtaining good retinopathy diabetic diagnosis in digital retinal images. The use of filter bank has shown to be a powerful technique for detecting blood vessels. In particular, the Matched Filter is appropriate and efficient for this task and in combination with other methods the blood vessel detection can be improve...
