“Application of pattern recognition and texture analysis methods on cancer imaging data”

Dr Maria Venianaki Institute of Computer Science (ICS)

Abstract
Cancer research has significantly advanced in recent years mainly through developments in medical genomics and bioinformatics. From the imaging perspective, imaging biomarkers have been proposed in numerous studies as a cost-effective, non-invasive method for cancer diagnosis, monitoring and therapy outcome prediction, as they can provide important anatomical and functional information at an early stage of therapy. However, the extraction of imaging biomarkers is still an open problem, as there are no standard imaging protocols or established methods. Pharmacokinetic models are the most commonly used technique for analyzing dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) data and extracting imaging biomarkers. However, these models have several limitations such as their computational complexity, which often results in high variability of the computed biomarkers.
In this talk, we will first present the fundamentals of the DCE-MRI technique, which is a noninvasive imaging method that can provide information concerning tissue oxygenation and vascularization at high spatial resolution. We will then discuss data-driven, model-free biomarker extraction strategies relying on the classification of time intensity curves. Specifically, pattern recognition techniques for the extraction of enhancement patterns from DCE-MRI data will be presented. Results from different cancer imaging datasets will be shown as different case studies. Finally, we will discuss the extraction of texture-based imaging biomarkers from DCEMRI data and their application on the prediction of treatment response.

” Advanced femtosecond beam tailoring for generation of functional biomimetic textures on metallic surfaces ”

Dr. Fraggelakis Fotis Institute of Electronic Structure and Laser (IESL)

Abstract

A vast gamut of functional surfaces that exhibit extraordinary properties can be found in nature. Derived after millions of years of evolution, those surfaces incorporate the successful result of an almost infinite number of trials and hold a potential to make a real breakthrough for material applications in our everyday life. Among those functionalities are, superhydrophobicity, antireflectivity, wear reduction and omniphobicity. Several of the properties of natural surfaces match demands for functional surfaces in materials industry. From everyday applications like antireflective smartphone screens to antibiofouling medical tools and frictionless metals in automotive industry, the necessity to design materials with tailored surface properties becomes more and more prominent. Femtosecond laser surface texturing already proved its value in mimicking bioinspired functionalities. Nevertheless, despite the progress to date in laser texturing, mimicking the extraordinary variety and complexity of natural surfaces at the nanoscale, i.e. beyond the light diffraction limit, is far from being accomplished. Indeed, functional surfaces found in nature comprise a broad range of characteristic sizes often near or even well below the microscale and exhibit complex hierarchical morphologies with multiple axes of symmetry. On the contrary, the Laser Induced Periodic Surface Structures (LIPSS), which can be induced in almost any solid surface, exhibit single-axis symmetry, while their period is close to or higher than the laser’s wavelength used for texturing. In the presented work we combine state of the art techniques like temporal and spatial beam shaping to enable the desired level of control over the laser induced nanostructure’s symmetry and
directionality, particularly beyond the diffraction limit, for the fabrication of complex hierarchical biomimetic structures on metallic surfaces.

” Achromatic Metasurfaces for Temporal and Spatial Control of Electromagnetic Waves”

Dr. Odysseas Tsilipakos Institute of Electronic Structure and Laser (IESL)

Abstract
Metasurfaces are ultra-thin, two dimensional versions of metamaterials. They hold the promise of revolutionizing wave control by replacing conventional bulky optical components, thus leading to important size, weight, and planar fabrication advantages. However, conventional metasurfaces suffer from large chromatic aberrations and cannot sustain their performance over broad spectral bandwidths. In this talk, we will discuss the theoretical and practical requirements for designing achromatic metasurfaces that can accommodate broadband signals encountered in real-world applications. In the first part, we will focus on achromatic metasurfaces that can delay broadband pulses without distorting the pulse shape; the relevant applications include delay lines and shorttime memory modules. In the second part, we will discuss achromatic metasurfaces for wavefront control with an emphasis on beam steering and beam focusing operations; the relevant applications include microscopy, antennas, and spatial light modulators. More generally, we will show that 3D bulk structures such as lenses, wedges and gratings can be squeezed into a single 2D surface, bearing important physical and technological implications.

“Advanced Oxides for Environmental and Energy Applications”

Dr. Vassilios Binas Institute of Electronic Structure and Laser (IESL)

Abstract
The global concerns in the development of human civilization, the scientific and technological issues of energy utilization and environment protection are currently facing challenges. Nowadays, enormous energy demands of the world are mainly met by the non-renewable and environmental unfriendly fossil fuels. The substitution of the conventional energy platform has become extremely urgent, in the pursuit of the renewable and clean energy sources and carriers, including hydrogen storage, CO2 convention, batteries, and supercapacitors. Additionally, long-term industrial and agricultural activities induce serious environmental pollution problems (such as greenhouse and toxic gases, pharmaceuticals and organic micro-polutants) in air and water to deteriorate the ecological balance and the daily human health. The use of solar energy to drive the chemical and energy processes, along with chemical storage of solar energy and air – water cleaning, are imperative for the transition to a low-carbon economy, sustainable and clean society Realizing these challenges requires the development of new ideas, concepts and innovative photocatalytic materials. Advanced oxides (metal oxides and perovskite type nanomaterials) are of great technological importance in energy and environmental applications because if their capability to generate charge carriers when stimulated with a required amount of energy. The promising arrangement of electronic structure, light absorption properties, and charge transport characteristics of most of oxides render them potential candidates particularly for effective environmental and energy applications. Moreover, these materials can be synthesized with low cost, high yield, through easily controlled solution-based techniques. In this presentation, we discuss the use of advanced oxides as photocatalytic materials for the sustainable development in the energy (H2 production etc) and environment (improve air, water and health quality) applications.

“Neuro-inspired Compression of Images and Videos (NICE2)”

Dr. Effrosyni Doutsi Institute of Computer Science (ICS)

Abstract
In recent years the widespread use of multimedia devices has increased the volume of digital data. Compression algorithms are necessary to store and process this copious amount of data. Unfortunately, these algorithms are developing very slowly while at the same time their complexity is constantly increasing. For this reason, the signal processing community is looking for solutions that will improve the capabilities of compression algorithms in other disciplines, such as neuroscience. Understanding and decrypting the brain has gained scientific interest as it is considered one of the most sophisticated systems yet capable of managing and compressing large volumes of information. In this talk I will introduce our image compression architecture that is based on neuroscience models. We have developed tools that enable to encode the visual information by mimicking the spiking neurons without sacrificing the quality of the reconstruction. In addition, using machine learning-based image quality metrics, we show that the proposed compression system performs much better in terms of perception than the state-of-the-art.

“How does the brain pay attention?”, Dr. Panos Sapountzis [Oct 9, 2018]

“How does the brain pay attention?”

Dr. Panos Sapountzis Institute of Applied and Computational Mathematics (IACM)

Abstract
Attention is a cognitive function that allows to prioritise objects or locations that are most relevant to behaviour. The ability to flexibly guide our attention to the most relevant stimuli is critical for normal behaviour and is known to be disrupted in several neuropsychiatric and neurological disorders. Thus, understanding the neural substrates of attention is of significant importance. Invasive electrophysiological studies that aim at understanding the computations that individual neurons and neuronal ensembles carry out during attention have provided most of our knowledge on the role of different brain areas in the mechanisms of attention. These studies have implicated a distributed network of brain regions including area LIP in the parietal and area FEF in the prefrontal cortex. Despite converging evidence about the instrumental role of these regions in the control of attention, the particular contribution of each area in different aspects of attention has not been fully elucidated. Moreover, it is largely unexplored how activities across distant neuronal ensembles are coordinated and how effective communication between distant areas is implemented during attention. By performing simultaneous extracellular recordings in the two areas, we found that the behavioural relevance of stimuli is more robustly encoded in the prefrontal, relative to the parietal cortex. However, information emerges simultaneously in neuronal subpopulations in the two areas. Thus, our results indicate that attentional priority signals are processed in a parallel, distributed manner within the frontoparietal network. Moreover, we found that oscillatory interactions between the two regions have distinct frequency profiles in different task epochs. These data suggest that synchrony at distinct frequency bands reflects communication principles that subserve different cognitive requirements.

“Sharp weighted Finsler-Kato inequalities for anisotropic Laplacian”, Dr. Konstantinos Tzirakis [Sep 24, 2019]

“Sharp weighted Finsler-Kato inequalities for anisotropic Laplacian”

Dr. Konstantinos Tzirakis Institute of Applied and Computational Mathematics (IACM)

Abstract
The talk concerns recent developments in anisotropic weighted Kato type inequalities – with the anisotropy being represented by a generic Finsler metric – which are associated to the so-called Finsler or anisotropic Laplacian. The Finsler Laplacian is one of the most natural and foremost operators in the theory of anisotropic and non-homogeneous media, and in Finsler or Minkowski geometry. Following a unifying approach, we establish first a sharp interpolation between anisotropic weighted Hardy and Kato inequalities, in the half-space, extending the corresponding non-weighted version, being established recently by a different approach. Then, passing to bounded domains, we obtain successive sharp improvements by adding correction terms involving sharp weights and optimal constants, resulting in an infinite series-type improvement. We also discuss the optimality of the weights and the constants of the remainder terms, the results within the special Euclidean context, as well as the application of our method for cones.
