Abstract:
... Cell-based assays including both cell identification assays and cell functional assays are broadly used in life science research and for medical applications. Traditionally, cell-based assays are performed in professional laboratories. Although such an approach is reliable, it significantly limits the accessibility of cell-based assays by many researchers without specialized cell imaging facilitie ...

Abstract:
... Deciding what to eat often implies a conflict between immediate goals (I need to eat, ideally something enjoyable) and long-term goals (I need to be healthy), particularly when choosing between foods superior on a hedonic dimension (referred to as vices) and foods superior on an utilitarian dimension (referred to as virtues). One sort of intervention that could potentially shift balance between sh ...

Sum frequency generation (SFG) images of microcontact patterned self-assembled alkanethiol monolayers on metal surfaces were analyzed by factor analysis (FA) to determine the spatial distribution of the patterned monolayers over the images. Additionally, each significant abstract factor produced by FA was assessed to determine the information contained within it. These results indicate that FA of ...

We report, for the first time, the three dimensional reconstruction (3D) of a transistor from a microprocessor chip and roughness of molecular electronic junction obtained by electron tomography with Hole Free Phase Plate (HFPP) imaging. The HFPP appears to enhance contrast between inorganic materials and also increase the visibility of interfaces between different materials. We demonstrate that t ...

The method comprises three components to maintain an accurate alignment on overlapping areas while taking advantage of outliers to approximate the non-overlapping areas. First, a penalty matrix is designed to be as the prior f ...

Abstract:
... Low-contrast and dayglow contamination pose a challenge to the accurate contour extraction of the auroral oval captured by the ultraviolet imager (UVI). To address the segmentation difficulties, a novel prior shape-based level-set method (PSLSM) is proposed by introducing prior knowledge into the variational framework. Firstly, driven by the local information term and the distance constraint term, ...

Abstract:
... The qHAADF method allows the quantification of the composition at atomic column resolution in semiconductor materials by comparing the HAADF-STEM intensities between a region of interest to a region of the material of known composition. However, the application of this qHAADF approach requires both regions to be differentiable and included in the same micrograph at close proximity. This limits the ...

Abstract:
... In situ quantification of the meso-structural changes in block-in-matrix-soils (bimsoil) is crucial for stability predictions. While the macroscopic failure of bimsoil has been widely studied, the physical meso-scale mechanisms governing bimsoil deformation have not been well understood. Here, high energy X-ray computed tomography (CT) measurements were performed on a bimsoil sample with a rock bl ...

However, the microstructure is highly complex and numerous image defects such as vague or missing boundaries formed during sample preparation, which makes it difficult to extract the grain boundaries precisely. In this work, we address the tas ...
