ERC FUNDED PROJECTS

Optimization problems are ubiquitous in computer science. Almost every problem involves the optimization of some objective function. However a major part of these problems cannot be solved to optimality. Therefore, algorithms that achieve provably good performance guarantees are of immense importance. Considerable progress has already been made, but great challenges remain: Some fundamental problems are not well understood. Moreover, for central problems arising in new applications, no solutions are known at all. The goal of APEG is to significantly advance the state of the art on algorithmic performance guarantees. Specifically, the project has two missions: First, it will develop new algorithmic techniques, breaking new ground in the areas of online algorithms, approximations algorithms and algorithmic game theory. Second, it will apply these techniques to solve fundamental problems that are central in these algorithmic disciplines. APEG will attack long-standing open problems, some of which have been unresolved for several decades. Furthermore, it will formulate and investigate new algorithmic problems that arise in modern applications. The research agenda encompasses a broad spectrum of classical and timely topics including (a) resource allocation in computer systems, (b) data structuring, (c) graph problems, with relations to Internet advertising, (d) complex networks and (e) massively parallel systems. In addition to basic optimization objectives, the project will also study the new performance metric of energy minimization in computer systems. Overall, APEG pursues cutting-edge algorithms research, focusing on both foundational problems and applications. Any progress promises to be a breakthrough or significant contribution.

Half of “late talkers”, infants who are not yet speaking by 2 years of age, will go on to develop language impairments. Currently, we have no reliable means of identifying these infants. Here we combine our developmental approach to phonology (psycholinguistic grain size theory), to the neural mechanisms underlying speech encoding (temporal sampling [TS] theory) and our work on the developmental importance of the speech amplitude envelope (AE) to open a new research front in the foundations of language acquisition. Recent adult research confirms our decade-long focus on the importance of sensitivity to AE ‘rise time’ in children’s language development, showing that rise times (‘auditory edges’) re-set the endogenous cortical oscillations that encode speech. Accordingly, we now apply our in-house state-of-the-art methods for measuring oscillatory rhythmic entrainment in children along with our recent theoretical and behavioural advances concerning AE processing to infant studies. Our core aim is to use the TS theoretical perspective and analysis methods to generate robust early neural and behavioural markers of phonological and morphological development: TS for infants. We have published the first-ever studies of oscillatory entrainment to speech rhythm by children and we have developed methods for technically-challenging EEG speech envelope reconstruction. We now apply these innovative methods to infant language learning and infant-directed speech. Using our cutting-edge EEG methods, we will deliver a novel and innovative road map for charting early language acquisition from a rhythmic entrainment perspective. Our recent 5-year study of rise time sensitivity in infants confirms the feasibility of a TS approach. As our focus is on prosody, syllable stress and syllable processing, our methods will apply across European languages.

Peptide building blocks serve as very attractive bio-inspired elements in nanotechnology owing to their controlled self-assembly, inherent biocompatibility, chemical versatility, biological recognition abilities and facile synthesis. We have demonstrated the ability of remarkably simple aromatic peptides to form well-ordered nanostructures of exceptional physical properties. By taking inspiration from the minimal recognition modules used by nature to mediate coordinated processes of self-assembly, we have developed building blocks that form well-ordered nanostructures. The compact design of the building blocks, and therefore, the unique structural organization, resulted in metallic-like Young's modulus, blue luminescence due to quantum confinement, and notable piezoelectric properties. The goal of this proposal is to develop two new fronts for bio-inspired building block repertoire along with co-assembly to provide new avenues for organic nanotechnology. This will combine our vast experience in the assembly of aromatic peptides together with additional structural modules from nature. The new entities will be developed by exploiting the design principles of small aromatic building blocks to arrive at the smallest possible module that form super helical assembly based on the coiled coil motifs and establishing peptide nucleic acids based systems to combine the worlds of peptide and DNA nanotechnologies. The proposed research will combine extensive design and synthesis effort to provide a very diverse collection of novel buildings blocks and determination of their self-assembly process, followed by broad chemical, physical, and biological characterization of the nanostructures. Furthermore, effort will be made to establish supramolecular co-polymer systems to extend the morphological control of the assembly process. The result of the project will be a large and defined collection of novel chemical entities that will help reshape the field of bioorganic nanotechnology.

From testicular grafting (1920s) to step counting watches (2014), the perceptions and practices of health seeking individuals have been marked by continuities and profound changes during a twentieth century largely shaped by the advent of a communication society. Visuals can be a source to understand transformations by postulating an interactive, performative power of mass media in societies. Which roles did visuals play in changes from public health and human capital collective understandings of the healthy self to new (sometimes debated) perceptions and practices of our bodies as forms of individual capital in an increasing market-economized world? Pursuing these questions, the project focuses on four fields of investigation -food/nutrition; movement/exercise/sports; sexuality/reproduction/infants and dependency/addiction/overconsumption- in Germany, France and Great Britain studied with an entangled history framework. Within this scope the project aims at understanding (1)how visuals shape our health related self-understandings and practices in a continuity/discontinuity from the bio-political to the bio-economic logic. (2) The project will explore and explain how and why understandings of body capital differ or overlap in European countries. (3) The project will analyse if and how visual media serve as a promotion-communication hyphen for twentieth century preventive-self understanding. With a visual perspective on a long twentieth century, the project seeks to better understand changes and continuities in the history of health intertwined with the history of media. This will provide new insights into how the internalization of bodycapital has evolved throughout the past century, how transformations in the media world (from film to TV to internet) play out at the individual level and how health challenges and cultural differences in body perceptions and practices persist in producing social distinction in an age of global information and advanced health systems.
