Vision-based 3-D head detection and tracking systems have been studied in several applications like video surveillance, face-detection systems, and occupant posture analysis. In this paper, we present the development of a topology-based framework using a 3-D skeletal model for the robust detection and tracking of a vehicle occupant's head position from low-resolution range image data for a passive safety system. Unlike previous approaches to head detection, the proposed approach explores the topology information of a scene to detect the position of the head. Among the different available topology representations, the Reeb graph technique is chosen and is adapted to low-resolution 3-D range images. Invariance of the graph under rotations is achieved by using a Morse radial distance function. To cope with the particular challenges such as the noise and the large variations in the density of the data, a voxel neighborhood connectivity notion is proposed. A multiple-hypothesis tracker (MHT) with nearest-neighbor data association and Kalman filter prediction is applied on the endpoints of the Reeb graph to select and filter the correct head candidate out of Reeb graph endpoints. A systematic evaluation of the head detection framework is carried out on full-scale experimental 3-D range images and compared with the ground truth. It is shown that the Reeb graph topology algorithm developed herein allows the correct detection of the head of the occupant with only two head candidates as input to the MHT. Results of the experiments demonstrate that the proposed framework is robust under the large variations of the scene. The processing requirements of the proposed approach are discussed. It is shown that the number of operations is rather low and that real-time processing requirements can be met with the proposed method. [less ▲]

By uncertainty, we define an archaeological expert's level of confidence in an interpretation deriving from gathered evidence. Archaeologists and computer scientists have urged caution in the use of 3D for archaeological reconstructions because the availability of other possible hypotheses is not always being acknowledged. This poster presents a 3D visualization system of archaeological uncertainty. [less ▲]

Individuals continually interact with security mechanisms when performing tasks in everyday life. These tasks may serve personal goals or work goals, be individual or shared. These interactions can be influenced by peers and superiors in the respective environments (workplace, home, public spaces), by personality traits of the users, as well as by contextual constraints such as available time, cognitive resources, and perceived available effort. All these influencing factors, we believe, should be considered in the design, implementation and maintenance of good socio-technical security mechanisms. Therefore, we need to observe reliable socio-technical data, and then transform them into meaningful and helpful metrics for user interactions and influencing factors. More precisely, there are three main questions that the group discussed: 1. What data do we need to observe and what of this data we actually can observe and measure? 2. How can we observe and measure? 3. What can we do with the results of the observations? [less ▲]

The "4D Biology Workshop for Health and Disease", held on 16-17th of March 2010 in Brussels, aimed at finding the best organising principles for large-scale proteomics, interactomics and structural genomics/biology initiatives, and setting the vision for future high-throughput research and large-scale data gathering in biological and medical science. Major conclusions of the workshop include the following. (i) Development of new technologies and approaches to data analysis is crucial. Biophysical methods should be developed that span a broad range of time/spatial resolution and characterise structures and kinetics of interactions. Mathematics, physics, computational and engineering tools need to be used more in biology and new tools need to be developed. (ii) Database efforts need to focus on improved definitions of ontologies and standards so that system-scale data and associated metadata can be understood and shared efficiently. (iii) Research infrastructures should play a key role in fostering multidisciplinary research, maximising knowledge exchange between disciplines and facilitating access to diverse technologies. (iv) Understanding disease on a molecular level is crucial. System approaches may represent a new paradigm in the search for biomarkers and new targets in human disease. (v) Appropriate education and training should be provided to help efficient exchange of knowledge between theoreticians, experimental biologists and clinicians. These conclusions provide a strong basis for creating major possibilities in advancing research and clinical applications towards personalised medicine. [less ▲]

Il ne s’agit pas de produire un récit exhaustif ou apologétique ou exclusif de la conscience européenne. Il s’agit de rendre visible la réalité mouvante d’une conscience européenne qui s’affirme de plus en plus en Europe. Pour n’avoir aucun lieu où se penser et où se refléter, celle-ci est bien souvent abandonnée à elle-même au point de douter de sa réalité propre. Mais les enjeux politiques, économiques et culturels de l’Europe politique sont tels que l’Union européenne ne pourra plus se permettre trop longtemps de se passer de récit commun. [less ▲]

2-Oxoglutarate and iron dependent oxygenases are therapeutic targets for human diseases. Using a representative 2OG oxygenase panel, we compare the inhibitory activities of 5-carboxy-8-hydroxyquinoline (IOX1) and 4-carboxy-8-hydroxyquinoline (4C8HQ) with that of two other commonly used 2OG oxygenase inhibitors, N-oxalylglycine (NOG) and 2,4-pyridinedicarboxylic acid (2,4-PDCA). The results reveal that IOX1 has a broad spectrum of activity, as demonstrated by the inhibition of transcription factor hydroxylases, representatives of all 2OG dependent histone demethylase subfamilies, nucleic acid demethylases and gamma-butyrobetaine hydroxylase. Cellular assays show that, unlike NOG and 2,4-PDCA, IOX1 is active against both cytosolic and nuclear 2OG oxygenases without ester derivatisation. Unexpectedly, crystallographic studies on these oxygenases demonstrate that IOX1, but not 4C8HQ, can cause translocation of the active site metal, revealing a rare example of protein ligand-induced metal movement.

The authors demonstrate that a 550GHz bandwidth photodetector can be fabricated on low-temperature grown MBE GaAs. The pulse response shows 0.4 and 0.6ps rise and fall times, respectively. The bandwidth is in agreement with a value calculated using a carrier lifetime of 0.2ps, measured by femtosecond time-resolved reflectivity, and a capacitance of 0.014fF/um2, determined from microwave measurements. The device bandwidth is RC limited. [less ▲]
