    Contaminant events disrupt stability and resilience of increasingly vulnerable soil and groundwater. Identifying where, when and how much contaminant spill is released into aquifers is critical for strengthening the competitiveness of EU in risk-reduction management, and Forensic Hydrogeology, a growing discipline that applies scientific knowledge in legal resolutions. Existing model solutions estimate the origin and affected area, but numerical challenges impose too restrictive assumptions to properly account for multiple sources or suitable aquifer characterization. The scientific goal of FORENSHYD is to develop a novel, flexible and reliable ensemble Kalman filter data assimilation method (EnKF) for the optimal identification of contaminant sources and occurrence of reactive pollutants in near-actual conditions. Latest assessed developments of Dr. Gómez-Hernández set EnKF as an excellent optimization tool for the simultaneous identification of the spatial variability of conductivities, the location, and the release function of polluting sources. A step toward coupling the algorithm with machine learning techniques may overcome ill-posed solutions, stemmed from nonlinearities between parameters and variables in the state equation, to solve kinetic-controlled reactive transport problems and to optimize data collection in groundwater observation network systems, a topic of renewal interest in administration and industrial sector. We test spurious effects of aquifer heterogeneity, reactive parameters, and initial/boundary conditions in synthetic scenarios, sandbox experiments and two demonstration sites. Transfer of this novel technology in well-reported, practical and universal open source packages will reinforce the leadership and employability in the global market of intersectorial and interdisciplinary European stakeholders. The societal value of FORENSHYD is to improve mitigation strategies, and clarify environmental liability, in liaises with Horizon 2020.

    Information and communication technology (ICT) systems are expanding at an awesome pace in terms of capacity demand, number of connected end-users and required infrastructure. To cope with these rapidly increasing growth rates there is a need for a flexible, scalable and future-proof solution for seamlessly interfacing the wireless and photonic segments of communication networks. RF or Microwave photonics (MWP), is the best positioned technology to provide the required flexible, adaptive and future-proof physical layer with unrivalled characteristics. Its widespread use is however limited by the high-cost, non-compact and heavy nature of its systems. Integrated Microwave Photonics (IMWP) targets the incorporation of MWP functionalities in photonic chips to obtain cost-effective and reduced space, weight and power consumption systems. IMWP has demonstrated some functionalities in through application specific photonic circuits (ASPICs), yielding almost as many technologies as applications and preventing cost-effective industrial manufacturing processes. A radically different approach is based on a universal or general-purpose programmable photonic integrated circuit (PIC) capable of performing with the same hardware architecture the main required functionalities. The aim of this project is the design, implementation and validation of such processor based on the novel concept of photonic waveguide mesh optical core and its integration in a Silicon Photonics chip. Its three specific objectives are: (1) The architecture design and optimization of a technology-agnostic universal MWP programmable signal processor, (2) The chip mask design, fabrication and testing of the processor and (3) The experimental demonstration and validation of the processor. Targeting record values in bandwidth and footprint its potential impact will be very large by unlocking bandwidth bottlenecks and providing seamless interfacing of the fiber and wireless segments in future ICT systems.

    Extreme events often cause local-initial damage to the critical elements of building structures, followed by a cascade of further failures in the rest of the building; a phenomenon known as “progressive collapse”. Current design philosophies are based on giving buildings extensive continuity, so that when a critical element fails its load can be re-distributed among the rest of the structure. However, in certain situations (e.g. initial failure of several columns) this extensive continuity introduces undesirable effects and actually increases the risk of progressive collapse. Segmenting a building into individual units connected only by means of fuses would avoid a failure in one zone propagating to others. While such fuses would provide continuity for normal loads or small local-initial failure, they would “isolate” the different parts of the building when otherwise the forces generated by the initial failure would pull down the rest of the structure. Although fuse segmentation is probably the only alternative that can fill the gaps in the present design philosophies, so far, no studies have been carried out on the possibility of applying it to buildings. Endure’s overall aim is to develop a novel fuse-based segmentation design approach to limit or arrest the propagation of failures in building structures subjected to extreme events. The project will be multidisciplinary and highly ambitious, and will achieve its overall aim by: 1) Developing a performance-based approach for the design of fuse-segmented buildings; 2) Designing, manufacturing and testing fuses for segmenting buildings; and 3) Implementing fuses in segmented realistic building prototypes and testing and validating the new fuse-based approach in these structures. Endure will open up a new research area and design approach, and also deliver novel construction procedures. The project will lead to safer buildings, especially in the case of extreme events with severe consequences for building integrity.

    Breast cancer is the most common cancer globally, accounting for 12% of all new annual cancer cases worldwide, according to the World Health Organization, and early detection is a key issue as survival improves when cancer is detected early. NanoNIR will develop a novel fluorescence-based nanotool for the detection and quantification of miR-99a-5p in liquid biopsy samples from breast cancer patients. The nanotool will consist of upconverting nanoparticles (UCNPs) decorated with aptamers and small gold nanoparticles (AuNPs). UCNPs are inorganic nanocrystals that convert near-infrared (NIR) light into shorter wavelength emissions and exhibit narrow emission bandwidths and large anti-Stokes shifts (λex = 980 nm, λem = 540, 655 nm). These photophysical properties make them excellent candidates for fluorescence biosensing allowing for effective sensing with diminished background noise in a complicated detection system. The AuNPs have a large extinction coefficient and a broad UV–Vis absorption band (500 – 580 nm) making them excellent fluorescence quenching agents. The combination of UCNPs (donors) with AuNPs (acceptors) linked through complementary aptamers will result in a fluorescence emission quenching of UCNPs at 540 nm. Following the detection of miR-99a-5p by its complementary aptamer sequence, AuNPs will be displaced from the UCNPs surface restoring the luminescence of UCNPs at 540 nm with an intensity-dependent to miRNA-9a-5p concentration allowing the detection of miR-99a-5p in real samples. Additionally, the luminescence signal at 655 nm could be used for the ratiometric measurements.
