Rapid detection of apoptosis in mammalian cells by using intact cell MALDI mass spectrometry.

Detection of cell death has extensive applications and is of great commercial value. However, most current high-throughput cell viability assays cannot distinguish the two major forms of cell death: apoptosis and necrosis. Many apoptosis-specific detection methods exist but they are time consuming and labour intensive.

Dot scissor: a single-click interface for mesh segmentation.

This paper presents a very easy-to-use interactive tool, which we call dot scissor, for mesh segmentation. The user's effort is reduced to placing only a single click where a cut is desired. Such a simple interface is made possible by a directional search strategy supported by a concavity-aware harmonic field and a robust voting scheme that selects the best isoline as the cut.

Mesh segmentation with concavity-aware fields.

This paper presents a simple and efficient automatic mesh segmentation algorithm that solely exploits the shape concavity information. The method locates concave creases and seams using a set of concavity-sensitive scalar fields. These fields are computed by solving a Laplacian system with a novel concavity-sensitive weighting scheme.

Bilateral normal filtering for mesh denoising.

Decoupling local geometric features from the spatial location of a mesh is crucial for feature-preserving mesh denoising. This paper focuses on first order features, i.e.

Dual Laplacian editing for meshes.

Recently, differential information as local intrinsic feature descriptors has been used for mesh editing. Given certain user input as constraints, a deformed mesh is reconstructed by minimizing the changes in the differential information. Since the differential information is encoded in a global coordinate system, it must somehow be transformed to fit the orientations of details in the deformed surface, otherwise distortion will appear.
