We have investigated the formation of the prestalk-prespore pattern in Dictyostelium discoideum. Pattern formation occurs in clumps of Dictyostelium cells embedded in agar under a 100% oxygen atmosphere. Agar embedding allows us to control spatially the environment surrounding the cell clumps. Our results suggest that the ambient oxygen concentration plays a role in controlling the size of the ...
OBJECTIVE The purpose of this study was to investigate baseline postural stability of a normal healthy population using the modified balance error scoring system (M-BESS) integrated with H-pattern testing (HP) and cervical range of motion with fixed ocular gaze (CROM). METHODS Postural error scores for twelve participants were scored during each twenty second trial of the M-BESS protocol stan...
If an ultrasonic signal is introduced into or generated within a structure, the state of the structure governs its propagation and detection. The assessment of the state of the structure can be affected by material properties, geometrical properties, environmental conditions, and measurement conditions. Because of the large number of possible properties and conditions, the quantitative ultrason...
This paper investigates the time series representation methods and similarity measures for sensor data feature extraction and structural damage pattern recognition. Both model-based time series representation and dimensionality reduction methods are studied to compare the effectiveness of feature extraction for damage pattern recognition. The evaluation of feature extraction methods is performe...
This paper analyzes a generalization of a new metric to evaluate the classification performance in imbalanced domains, combining some estimate of the overall accuracy with a plain index about how dominant the class with the highest individual accuracy is. A theoretical analysis shows the merits of this metric when compared to other well-known measures.
The geometrical structure of the Indian elephant bell is presented and the requirements on its normal modes from group representation theory are described. These are in good agreement with the results of a finite-element model (FEM) for a specific 16-tine case. The spectrum consists of a sequence of families of modes lying on saturation curves, completely different from those of conventional be...
