In-network data aggregation is favorable for wireless sensor networks (WSNs): It allows in-network data processing while reducing the network traffic and hence saving the sensors energy. However, due to the distributed and unattended nature of WSNs, several attacks aiming at compromising the authenticity of the collected data could be perpetrated. For example, an adversary could capture a node ...

The importance of nodes in a network constantly fluctuates based on changes in the network structure as well as changes in external interest. We propose an evolving teleportation adaptation of the PageRank method to capture how changes in external interest influence the importance of a node. This framework seamlessly generalizes PageRank because the importance of a node will converge to the Pag...

We describe a method for generating H-Anim character animation using general graphics tools and motion capture data. An H-Anim character model can be designed with a general graphics tool using a procedure that defines the skeletal hierarchy of a human character. The character model is then provided with motion capture data. H Anim character animation is generated and displayed using a general ...

A three dimensional model of an environment can be constructed using several images of the same scene at different camera angles. This technique has a wide variety of applications, including robotics, motion capture, and security systems. This approach does, however, pose one major challenge: the exact position of each camera must be known before assembling the spatial model of the scene. Some ...

capture ELISA system was developed for diagnosis of visceral leishmaniasis (VL) using a monoclonal antibody raised against an antigen previously detected in the urine of VL patients. Urine samples from confirmed VL cases from Yemen, Nepal, Spain, Sudan and Brazil were tested in the capture ELISA in comparison with urine samples from endemic and non-endemic areas along with urine samples from pa...

UiO-66 and analogues were successfully tailored to chemoselectively capture AsV oxyanions at the hydroxylated node and neutral AsIII species with the thiolated organic linkers. More efficient and faster uptake can be achieved with increasing defect densities, increasing pore aperture sizes, and decreasing particle sizes.

Indirect evidence of a sinoatrial pacemaker shift after programmed atrial stimulation in man is presented. Following electrically induced beats, time intervals and postextrasystolic morphology of atrial electrogram and P waves were scrutinized in 30 catheterization studies. Applying premature atrial stimulation, a decrease of the interval between the last basic atrial depolarization and the sti...

Graph contrastive learning (GCL) has been subject to more attention and widely applied numerous graph tasks such as node classification link prediction. Although it achieved great success even performed better than supervised methods in some tasks, most of them depend on node-level comparison, while ignoring the rich semantic information contained topology, especially for social networks. Howev...

This work-in-progress report investigates the problem of authenticated querying in sensor networks. Roughly, this means that whenever the sensor nodes process a query, they should be able to verify that the query was originated by a legitimate entity. I precisely define authenticated querying, analyze the design space for realizing it and propose solutions to this problem in presence of node ca...
