Organisms Reshape Sign Relations

Relations between organisms and the environment in the ageing process

We have modified the sexual Penna model by introducing the fluctuating environment and fluctuations representing physiological functions of individuals. Additionally, we have introduced the mother care corresponding to the protection against the delete-rious influence of the environment, the learning capacity of individuals corresponding to their immunity and adaptation to the environment fluct...

Large-scale Extraction of Protein/Gene Relations for Model Organisms

This paper presents new results for extraction of relational information from biomedical text. We have improved our system to both capture new types of linguistic constructions as well as new types of biological information (i.e.(de-)phosphorylation). The precision of our system is stable with a slight increase in recall. From almost one million PubMed abstracts related to four model organisms,...

Hydrophobic Compounds Reshape Membrane Domains

Cell membranes have a complex lateral organization featuring domains with distinct composition, also known as rafts, which play an essential role in cellular processes such as signal transduction and protein trafficking. In vivo, perturbations of membrane domains (e.g., by drugs or lipophilic compounds) have major effects on the activity of raft-associated proteins and on signaling pathways, bu...

Reasoning about Body-Parts Relations for Sign Language Recognition

Over the years, hand gesture recognition has been mostly addressed considering hand trajectories in isolation. However, in most sign languages, hand gestures are defined on a particular context (body region). We propose a pipeline to perform sign language recognition which models hand movements in the context of other parts of the body captured in the 3D space using the MS Kinect sensor. In add...
