Speech Title: "The (key) Role of Ergonomics in Digital Pathology"

 

Abstract: For more than a century that the optical microscope has been the pathologists primordial tool for detection/diagnosis of diseases such as cancer. Nowadays, digital pathology systems are not only the future but also the present. However, the huge size of whole-slide digital images, typically in the order of tens of gigapixel, makes it difficult for any image processing procedure and, therefore, any automatic analysis. Several studies highlight that the major challenges in this area are to achieve an image quality good enough and to provide an interactive visualization tool comparable to the experience of the optical microscope. Therefore, ergonomics and human-device interaction play a major role for the more generalized adoption of digital slides on daily clinical practice. Image viewing must be optimized to compete with the analogical viewing of traditional microscopes adopting a user interface carefully designed and using the most appropriated input devices to provide the friendliest and most effective environment with special emphasis on ergonomics. In this talk automatic segmentation algorithms for nucleoids identification on thyroid scraped slides will be addressed and IPATHSCOPE, a visualization tool developed with special emphasis on the ergonomics will be presented.

Speech Title: "Fuzzy Recurrence Analysis of Physiological Data"

 

Abstract: The concepts of fuzzy recurrence plots and scalable recurrence networks have recently been introduced. A fuzzy recurrence plot displays grayscale texture, which is informative for pattern analysis. Networks derived from fuzzy recurrence plots are scalable and can be naturally modeled as either unweighted or weighted. This talk presents several applications of fuzzy recurrence analysis of physiological data for pattern classification, including gait dynamics, computer keystroke time series, and photoplethysmography signals in control subjects and patients with neuro-degenerative diseases. Extension of fuzzy recurrence analysis to medical image data is also addressed in this talk.

Speech Title: "OMPetri: A New Petri Net Simulation Environment based on OpenModelica"

 

Abstract: This talk will focus to a new Petri net simulation shell based on the OpenModelica software tool. A user interface will be presented, which allows the access to the Petri net library (PNlib) of OpenModelica. The PNlib-Shell provides a powerful simulation environment. Based on this new shell Petri net models can be easily created, simulated and analyzed. In addition the new system includes basic features to check and evaluate the model and to analyze simulation results generated by the simulation back-end.

Speech Title: "Bacterial Gene Regulatory Mechanisms of Decision-Making"

 

Abstract: Cells use past events in order to make decisions on future actions. This decision making process is based on the crossing of pre-established, tuned thresholds. At the level of gene expression and genetic circuits, these thresholds are based on RNA and protein numbers that need to be reached in order to change the status quo of the cell functioning. They are based on both maximum and minimum protein numbers, as well as on time-lengths that these numbers must be maintained so as to overcome safeguard mechanisms protecting the cell from spurious fluctuations in molecular numbers. We used in vivo single-RNA time-lapse fluorescence microscopy to extract the skewness and kurtosis of the distribution of intervals between consecutive RNA production events in individual cells. From the analysis of multiple promoters, mutants, induction schemes, and media conditions, we show that skewness and kurtosis can be tuned independently from the mean and noise in RNA numbers, by tuning the rate-limiting steps in transcription initiation. As these steps are sequence dependent and subject to regulation, these results suggest that, in bacteria, threshold crossing by RNA numbers and, thus, decision making by gene regulatory networks, is evolvable and adaptable at the stage of transcription initiation.

Speech Title: "Volumetric Contour-Based Surface Reconstruction"

 

Abstract: Current imaging technology produces 3D sampled data that can be interpreted as a stack of 2D slices cutting through the studied object/specimen. Frequently the process of segmenting and identifying specific structures in the slices involves a delineation procedure that produces contours around the structure of interest in each slice. These contours then need to be connected in order to produce a 3D model of the structure. Given the noise properties and sampling resolutions of different imaging modalities, a single reconstruction technique is therefore unlikely to produce satisfactory results for all types of input. To address this issue, three volumetric contour-based surface reconstruction techniques have been developed. A volumetric/implicit approach has been taken because these types of techniques easily handle changes in topology and more robustly reconstruct complex multi-component, branching objects. The first two techniques are more suitable for sparse contour sets and are based on 2D level set morphing and 2D distance field interpolation. The third method is more appropriate for high density input that contains significant noise and utilizes an implicit point set model to create a smooth surface with user-specified error bounds. These three methods will be detailed and compared using numerous reconstruction results from a variety of contour datasets.
