A requirement for understanding morphogenesis is being able to quantify expansion at the cellular scale. Here, we present new software (RootflowRT) for measuring the expansion profile of a growing root at high spatial and temporal resolution. The software implements an image processing algorithm using a novel combination of optical flow methods for deformable motion. The algorithm operates on a...

Biological macromolecular complexes are of great interest for molecular biology and structure-based drug design as they are involved in core biological functions such as protein synthesis or cellular transport. They undergo large conformational transitions to achieve these functions. Therefore, characterization of structure and conformational flexibility of these macromolecular complexes is cru...

Nurses’ image has always been a concern among those in the profession. This study set to determine the professional image of nursing as perceived by nurses working in tertiary hospitals in Enugu State, Southeast Nigeria. The objectives were to assess the factors within the nursing profession that motivates the nurses to practice nursing, determine the organizational factors that inhibit nurses ...

Hierarchical structum occurs in biological vision systems and there is good reason to incorporate it into a model of computation for processing binary images. A mathematical formalism is presented which can describe a wide variety of operations useful in image processing and graphics. The formalism allows for two kinds of simple transformations on the values (called pyramids) of a set of cells ...

Purpose: Based on signal theory and legitimacy theory, this paper examines whether firms with financial reporting misstatements (restatements) would prefer conservative to send signals regarding their determinants of improving credibility legitimate organizational image in Taiwan. This further these reduce the demand for after replacing managers reveal restatements.
