The NanoMag project is to improve and redefine existing analyzing methods and in some cases, to develop new analyzing methods for magnetic nanostructures. Using improved manufacturing technologies we will synthesize magnetic nanoparticles with specific properties that will be analyzed with a multitude of characterization techniques (focusing on both structural as well as magnetic properties) and bring the experimental results together to obtain a self-consistent picture which describes how structural and magnetic properties are interrelated. This extensive survey will be used to define standard measurements and techniques which are necessary for defining a magnetic nanostructure and quality control. NanoMag brings together Europes and internationally leading experts in; manufacturing of magnetic single-core nanoparticles and magnetic multi-core particles, analyzing and characterization of magnetic nanostructures and national metrology institutes. In the consortium we have gathered partners within research institutes, universities and metrology institutes, all carrying out front end research and developing applications in the field of magnetic nanoparticles.

By combining accurate magnetic measurements of neural activity with near-simultaneous high-definition measurements of cerebral structure provided by novel methods in ultra-low-field magnetic resonance imaging (ULF MRI ) we will be able to image the dynamics of human brain function at unprecedented resolution and reliability. BREAKBEN will achieve a revolution in neuroimaging; we aim at breaking the barrier for measurement of neuronal currents by ULF MRI (neural current imaging; NCI) as well as breaking the nonuniqueness barrier for magnetoencephalography (MEG) by combining it with ULF MRI and accurately presented a priori information. A key aspect in utilizing the a priori information is injected current density imaging (CDI), which will inform us about the individual conductivity structure of the head. Using novel verification and validation approaches, we will demonstrate the unique advantages of these multimodal techniques. These breakthroughs will result in completely different workflows in brain imaging, also suitable for clinical use. We believe that we are at the edge of a qualitative technology jump with ULF MRI, its applications and combinations. This will lead to a wealth of new applications and revolutionize the way we do magnetism-based measurements of the nervous system. Europe has the unique chance to lead this revolution.

A scientific and technological paradigm change is taking place, concerning the way that very high performance time and frequency reference signals are distributed, moving from radio signal broadcasting to signal transport over optical fibre networks. The latter technology demonstrates performance improvements by orders of magnitude, over distances up to continental scale. Research infrastructures are developing several related technologies, adapted to specific projects and applications. The present project aims to prepare the transfer of this new generation of technology to industry and to strengthen the coordination between research infrastructures and the research and education telecommunication networks, in order to prepare the deployment of this technology to create a sustainable, pan-European network, providing high-performance clock services to European research infrastructures. Further this core network will be designed to be compatible with a global European vision of time and frequency distribution over telecommunication networks, enabling it to provide support to a multitude of lower-performance time services, responding to the rapidly growing needs created by developments such as cloud computing, Internet of Things and Industry 4.0. The project aims at partnership building and innovation for high performance time and frequency (clock) services over optical fibre networks and to prepare the implementation of such a European backbone network.

Our vision is to develop a suite of standardised non-invasive devices that will provide essential information about brain health in neurocritical care and neuromonitoring, with a particular emphasis on 1. traumatic brain injury: the silent epidemic of the third millennium and 2. hypoxia in newborn children. Survivors present permanent neurological conditions that have a profound impact on the quality of life of individuals and their families, and hence a large socio-economic impact. The key factors influencing these conditions and their treatment are the avoidance of brain hypoxia and metabolic disturbances and this is driving the transfer of new neuromonitoring systems to the bedside where they are being shown to have a transformative effect on patient care. BitMap will develop non-invasive photonics-based monitoring techniques and data analysis methods to provide biomarkers that could guide patient management. A cohort of multi-disciplinary Early Stage Researchers (ESRs), embedded in leading laboratories across Europe, will work together on an programme designed to address the key technological and clinical challenges in neurocritical care. The ESRs will benefit from the diverse range of expertise in advanced photonics and clinical application which will substantially enhance their research competitiveness and employability, and will together form a critical mass of skilled people working together towards new technologies for improved neuroclinical care. The challenges involved are fundamentally multi-disciplinary and therefore ESRs trained in a multi-disciplinary environment are essential if progress and clinical impact is to be made. There is currently no graduate programme producing researchers with these attributes, but there is a significant market for such PhDs in the rapidly developing area of biomedical optics and in general in medical imaging technology development. The BitMap project therefore addresses both a clinical and economic need.

The SeNaTe project is the next in a chain of thematically connected ENIAC JU KET pilot line projects which are associated with 450mm/300mm development for the 12nm and 10nm technology nodes. The main objective is the demonstration of the 7nm IC technology integration in line with the industry needs and the ITRS roadmap on real devices in the Advanced Patterning Center at imec using innovative device architecture and comprising demonstration of a lithographic platform for EUV and immersion technology, advanced process and holistic metrology platforms, new materials and mask infrastructure. A lithography scanner will be developed based on EUV technology to achieve the 7nm module patterning specification. Metrology platforms need to be qualified for N7s 1D, 2D and 3D geometries with the appropriate precision and accuracy. For the 7nm technology modules a large number of new materials will need to be introduced. The introduction of these new materials brings challenges for all involved processes and the related equipment set. Next to new deposition processes also the interaction of the involved materials with subsequent etch, clean and planarization steps will be studied. Major European stakeholders in EUV mask development will collaboratively work together on a number of key remaining EUV mask issues. The first two years of the project will be dedicated to find the best options for patterning, device performance, and integration. In the last year a full N7 integration with electrical measurements will be performed to enable the validation of the 7nm process options for a High Volume Manufacturing. The SeNaTe project relates to the ECSEL work program topic Process technologies More Moore. It addresses and targets as set out in the MASP at the discovery of new Semiconductor Process, Equipment and Materials solutions for advanced CMOS processes that enable the nano-structuring of electronic devices with 7nm resolution in high-volume manufacturing and fast prototyping.

Atomic clocks are the backbone of our modern communication and navigation technology, e.g. through the global positioning system (GPS). Improving these clocks will open up exciting new applications in geodesy, fleet tracking, autonomous vehicles, augmented reality and shed light on some of the most fundamental questions in research. Todays best atomic clocks lose only 1 second in 30 billion years, making them the most precise measurement devices ever built. However, such clocks are extremely delicate and susceptible to external perturbations; they can only be operated in specialized laboratories. We propose to develop a novel type of clock, based on a unique nuclear transition in Thorium-229. This nuclear clock will be fundamentally different from existing atomic clocks, which are based on transitions in the electron shell. It will be largely inert to perturbations, simpler by design, and holds the potential to outperform existing atomic clocks in terms of precision. So far, progress towards an application of the Thorium nuclear transition has been hampered by the extreme technological challenges related to the scarcity of 229Th, insufficient detector resolution, and exotic lasers frequencies. Suitable technology is only becoming available just now. Furthermore, this research demands supreme expertise in a variety of fields, encompassing nuclear and atomic physics, quantum optics, metrology, as well as detector- and laser technology. Our interdisciplinary consortium is assembled to precisely match these requirements, joining for the first time Europes leading research groups in the respective fields. The work will focus on two objectives; (i) finding clear evidence of the transition and measuring its frequency, and (ii) developing all key components required for operation of a nuclear clock. We are certain that next-generation satellite-based navigation technology and other precision timing applications will greatly benefit from more precise and robust clocks.

Postoperative delirium (POD) is characterized by the progressive deterioration of sensory/cognitive function after surgery with incidences of up to 30-80%. It is frequently followed by postoperative cognitive dysfunction (POCD) which tends to persist over time. In elderly patients, POCD resembles chronic dementia and appears to accelerate the cognitive decline in Alzheimer dementia. POD is strongly associated with subsequent dementia after 3.2 and 5.0 years of follow-up: odds ratio = 12.52 [95% CI, 1.86-84.21] corrected for baseline dementia, severity of illness, age. In an aging society like the EU, the socioeconomic implications of POD/POCD are therefore profound. At present no treatment exists and there are no established molecular or imaging biomarkers that allow risk and clinical outcome prediction. We will establish valid biomarkers panels for risk and clinical outcome prediction of POD/POCD in N=1200 surgical patients according to the regulatory requirements of the European Medicines Agency. Thus, a valuable database will be created not yet existing worldwide. Neuroimaging investigations, which directly provide information on brain structure/function, will include structural magnetic resonance imaging (MRI), diffusion tensor imaging (DTI), arterial spin labelling (ASL), functional magnetic resonance imaging with simultaneous electrophysiology (fMRI/EEG) and glutamate MR-spectroscopy (MRS). These investigations will be complemented by genetic/gene expression analyses (sequencing of cholinergic candidate genes/corresponding transcripts) and analyses of plasma and cerebrospinal fluid markers (inflammatory/metabolic). Supported by bioinformatics approaches, integration of neuroimaging data with knowledge from molecular biomarkers (multivariate expert system) is expected to allow patient stratification. This will greatly support decision-making before surgical intervention (balancing benefits and risks) as well as the development of novel therapies in POD/POCD.

Single-mode optical fiber is a highly efficient connecting medium used not only for optical telecommunications but also for the dissemination of ultrastable frequencies or timing signals. Ma et al. [Opt. Lett. 19, 1777 (1994)] described a measurement and control system to deliver the same optical frequency at two places, namely the two ends of a fiber, by eliminating the "fiber-induced phase-noise modulation, which corrupts high-precision frequency-based applications." I present a simple detection and control scheme to deliver the same optical frequency at many places anywhere along a transmission path, or in its vicinity, with a relative instability of 1 part in 1019. The same idea applies to radio frequency and timing signals. This considerably simplifies future efforts to make precise timing or frequency signals available to many users, as required in some large-scale science experiments. © 2014 Optical Society of America.
