description: Τα τελευταία χρόνια, η χρήση των κτηνιατρικών φαρμάκων (όπως τα αντιβιοτικά) και των φυτοφαρμάκων στην κτηνοτροφία, στην υδατοκαλλιέργεια και στη γεωργία είναι ένα φαινόμενο το οποίο αυξάνεται με ραγδαίο ρυθμό. Με τη χρήση αυτών καθίσταται δυνατή η πρόληψη και η θεραπεία ζωικών ασθενειών οφειλόμενων σε μικροοργανισμούς όπως είναι τα παράσιτα, τα βακτήρια κ.α. Ωστόσο, η εμφάνιση φαρμακευτικών καταλοίπων σε προϊόντα που παράγονται από αυτά τα ζώα και καταναλώνονται από τον άνθρωπο, μπορεί να θέσει σε σοβαρό κίνδυνο την υγεία του ανθρώπου. Γι’ αυτό καθίσταται απαραίτητος ο προσδιορισμός των ουσιών αυτών με διάφορες μεθόδους. Η συγκεκριμένη εργασία στοχεύει στην αναφορά των κύριων και πιο συχνών μεθόδων προετοιμασίας των δειγμάτων τροφίμων προς ανάλυση, αλλά και των αναλυτικών τεχνικών που χρησιμοποιούνται για τον προσδιορισμό των υπολειμμάτων φαρμακευτικών ουσιών στα τρόφιμα. Πιο συγκεκριμένα οι αναλυτικές τεχνικές διαχωρίζονται σε μικροβιακές, ανοσολογικές και φυσικοχημικές, με τις τελευταίες να κυριαρχούν σε αυτόν τον τομέα. Ανάμεσα στις χρωματογραφικές τεχνικές, η συνδυασμένη LC-MS/MS φαίνεται να υπερτερεί καθώς χαρακτηρίζεται από μεγάλη ευαισθησία και επιλεκτικότητα, ενώ παράλληλα με μία μόνο ανάλυση καθίσταται δυνατή η ποσοτικοποίηση πολλαπλών αναλυτών στόχων σε σύνθετες μήτρες τροφίμων.

description: Flat microfiltration mullite (3Al2O32SiO2) membranes were prepared via phase-inversion tape casting method. The sintering temperature has been reduced from 1700°C to 1450°C by adding 3 wt.% of magnesium oxide (MgO) as a sintering aid. The effect of this compound on the membrane properties was systematically investigated. The presence of MgO promoted at the same time a change in membrane morphology resulting in a symmetric structure, which is opposite to the asymmetrical structure obtained for mullite membranes prepared without this sintering aid. Porosity of 38.9% and average pore size of 2.33 μm was achieved. Water and n-heptane vapor adsorption analysis showed an increment in hydrophilic behavior due to MgO. The reduction of sintering temperature from 1700°C (MgO free) to 1450°C (MgO added) produced mechanical stable samples with flexural strength about 15.3 MPa. The membrane was resistant enough to withstand the water flux permeation test up to 3 bar. Compared to the pure mullite membranes, the MgO containing sample displayed higher water permeation fluxes, which might be related to both the larger superficial pore size and its hydrophilicity.

description: A resonant photoacoustic cell intended for laser-spectroscopy gas sensing is represented. This cell is a miniature imitation of a macro-scale banana-shaped cell developed previously. The parameters, which specify the cavity shape, are chosen so as not only to provide optimal cell operation at a selected acoustic resonance but also to reduce substantially the cell sizes. A miniaturized prototype cell (the volume of acoustic cavity of ~ 5 mm^3) adapted to the narrow diffraction-limited beam of near-infrared laser is produced and examined experimentally. The noise-associated measurement error and laser-initiated signals are studied as functions of modulation frequency. The background signal and the useful response to light absorption by the gas are analyzed in measurements of absorption for ammonia in nitrogen flow with the help of a pigtailed DFB laser diode oscillated near a wavelength of 1.53 um. The performance of prototype operation at the second longitudinal acoustic resonance (the resonance frequency of ~ 32.9 kHz, Q-factor of ~ 16.3) is estimated. The noise-limited minimal detectable absorption normalized to laser-beam power and detection bandwidth is ~ 8.07*10^(-8) cm^(-1) W Hz^(-1/2). The amplitude of the background signal is equivalent to an absorption coefficient of ~ 2.5*10^(-5) cm^(-1). Advantages and drawbacks of the cell prototype are discussed. Despite low absorption-sensing performance, the produced miniaturized cell prototype shows a good capability of gas-leak detection.

description: We set up a formalism to calculate the charge form factors of two-neutron halo nuclei with S-wave neutron-core interactions in the framework of the halo effective field theory. The method is applied to some known and suspected halo nuclei. In particular, we calculate the form factors and charge radii relative to the core to leading order in the halo EFT and compare to experiments where they are available. Moreover, we investigate the general dependence of the charge radius on the core mass and the one- and two-neutron separation energies.

description: Heavy quarkonium is one of the most investigated probes of the medium produced in heavy-ion collisions. In the past few years progress has been made in the description of its in-medium dynamics from QCD. Non-relativistic EFTs in particular allow one to define and compute rigorously the potential governing the real-time evolution of the bound state from QCD, showing that it is composed of a real and an imaginary part. The latter encodes the effect of scattering with the light constituents of the plasma and is oftentimes responsible for the dissociation of the bound state. The EFT approach and its main results, as well as comparisons with recent lattice data and phenomenological applications, are briefly reviewed here.

description: In semi-arid environments characterized by erratic rainfall and scattered primary production, migratory movements are a key survival strategy of large herbivores to track resources over vast areas. Veterinary Cordon Fences (VCFs), intended to reduce wildlife-livestock disease transmission, fragment large parts of southern Africa and have limited the movements of large wild mammals for over 60 years. Consequently, wildlife-fence interactions are frequent and often result in perforations of the fence, mainly caused by elephants. Yet, we lack knowledge about at which times fences act as barriers, how fences directly alter the energy expenditure of native herbivores, and what the consequences of impermeability are. We studied 2-year ungulate movements in three common antelopes (springbok, kudu, eland) across a perforated part of Namibia's VCF separating a wildlife reserve and Etosha National Park using GPS telemetry, accelerometer measurements, and satellite imagery. We identified 2905 fence interaction events which we used to evaluate critical times of encounters and direct fence effects on energy expenditure. Using vegetation type-specific greenness dynamics, we quantified what animals gained in terms of high quality food resources from crossing the VCF. Our results show that the perforation of the VCF sustains herbivore-vegetation interactions in the savanna with its scattered resources. Fence permeability led to peaks in crossing numbers during the first flush of woody plants before the rain started. Kudu and eland often showed increased energy expenditure when crossing the fence. Energy expenditure was lowered during the frequent interactions of ungulates standing at the fence. We found no alteration of energy expenditure when springbok immediately found and crossed fence breaches. Our results indicate that constantly open gaps did not affect energy expenditure, while gaps with obstacles increased motion. Closing gaps may have confused ungulates and modified their intended movements. While browsing, sedentary kudu's use of space was less affected by the VCF; migratory, mixed-feeding springbok, and eland benefited from gaps by gaining forage quality and quantity after crossing. This highlights the importance of access to vast areas to allow ungulates to track vital vegetation patches.

description: The observation of the exotic quarkonium state Z_c(3900) by the BESIII and Belle collaborations supports the concept of hadronic molecules. Charmonium states interpreted as such molecules would be bound states of heavy particles with small binding energies. This motivates their description using an effective theory with contact interactions. In particular, we focus on the electromagnetic structure of the charged state Z_c(3900). Using first experimental results concerning spin and parity, we interpret it as an S-wave molecule and calculate the form factors as well as charge and magnetic radii up to next-to-leading order. We also present first numerical estimations of some of these observables at leading order.

description: We present experimental results for the density of states (DOS) of a superconducting microwave Dirac billiard which serves as an idealized model for the electronic properties of graphene. The DOS exhibits two sharp peaks which evolve into van Hove singularities with increasing system size. They divide the band structure into regions governed by the \emph{relativistic} Dirac equation and by the \emph{non-relativistic} Schrödinger equation, respectively. We demonstrate that in the thermodynamic limit a topological transition appears as a neck-disrupting Lifshitz transition in the number susceptibility and as an excited state transition in the electronic excitations. Furthermore, we recover the finite-size scaling typical for excited state quantum phase transitions involving logarithmic divergences and identify a quasi-order parameter.

description: Topological insulators represent a new quantum state of matter which is characterized by peculiar edge or surface states that show up due to a topological character of the bulk wave functions. This review presents a pedagogical account on topological insulator materials with an emphasis on basic theory and materials properties. After presenting a historical perspective and basic theories of topological insulators, it discusses all the topological insulator materials discovered as of May 2013, with some illustrative descriptions of the developments in materials discoveries in which the author was involved. A summary is given for possible ways to confirm the topological nature in a candidate material. Various synthesis techniques as well as the defect chemistry that are important for realizing bulk-insulating samples are discussed. Characteristic properties of topological insulators are discussed with an emphasis on transport properties. In particular, the Dirac fermion physics and the resulting peculiar quantum oscillation patterns are discussed in detail. It is emphasized that proper analyses of quantum oscillations make it possible to unambiguously identify surface Dirac fermions through transport measurements. The prospects of topological insulator materials for elucidating novel quantum phenomena that await discovery conclude the review.

description: Consider a linear regression model with n-dimensional response vector, p-dimensional regression parameter beta and independent normally distributed errors. Suppose that the parameter of interest is theta = a^T beta where a is a specified vector. Define the s-dimensional parameter vector tau=C^T beta-t where C and t are specified. Also suppose that we have uncertain prior information that tau=0. Part of our evaluation of a frequentist confidence interval for theta is the ratio (expected length of this confidence interval)/(expected length of standard 1-alpha confidence interval), the scaled expected length of this interval. We say that a 1-alpha confidence interval for theta utilizes this uncertain prior information if (a) the scaled expected length of this interval is significantly less than 1 when tau=0, (b) the maximum value of the scaled expected length is not too large and (c) this confidence interval reverts to the standard 1-alpha confidence interval when the data happen to strongly contradict the prior information. Let hat{Theta}=a^T hat{beta} and hat{tau}=C^T hat{beta}-t, where hat{beta} is the least squares estimator of beta. We consider the particular case that that E((hat{tau}-tau)(hat{Theta}-theta))=0, so that hat{Theta} and hat{tau} are independent. We present a new 1-alpha confidence interval for theta that utilizes the uncertain prior informationthat tau=0. The following problem is used to illustrate the application of this new confidence interval. Consider a 2^3 factorial experiment with 1 replicate. Suppose that the parameter of interest theta is a specified linear combination of the main effects. Assume that the three-factorinteraction is zero. Also suppose that we have uncertain prior information that all of the two-factor interactions are zero. Our aim is to find a frequentist 0.95 confidence interval for theta that utilizes this uncertain prior information.

Engineering hierarchical architectures for bio-inspired photonics

Publisher: name: Imperial College London
Year: 2020

description: Complex nano- and micro-engineered hierarchical structures provide opportunities towards mimicking optical elements and functionalities found in nature. It has, however, been challenging to replicate certain architectures: for instance, those found in butterflies’ wings that are based on combined structural and pigmentary colouration mechanisms. Here we engineer such hierarchical structures consisting of diffraction gratings and nanoparticles of polystyrene or light-absorbing spherical particles made of a conjugated polymer as pigment. Simple geometrical relationships can be employed to program the particles into specific sites and form diverse patterns such as those in the wing scales: from ordered to disordered arrangements; hexagonal-packed or random-packed structures, to monolayer vs. multilayer architectures. As elucidated with model systems, this thesis’ research/findings may open a versatile design platform in terms of the fabrication of multifunctional nano- and microstructures with assembly hierarchies for use in the field of biomimetics, photonics and beyond.

 Notes. Hypoaspis terrestris is very distinctive in the extreme length of dorsal shield setae j3 and S5. The length of these setae separates this species from the related species H. polyphyllae, which was also present in our collections. Our specimens of H. terrestris show some variation in the length of seta j6, which sometimes reaches past the base of J1, but is noticeably shorter in other specimens. The only available illustrations of this species appear to be those of Bregetova (1977), which does not show the length of these setae. This species has been reported from USSR and Italy, in soil and on Copris hispanus and an unidentified species of Cetoniinae. We now record it on two species of beetles in Iran, Pentodon idiota and Polyphylla olivieri. Our specimens were found both on the larvae of P. olivieri in soil, and phoretic on the adult beetles. This is consistent with the original observations of Leonardi (1899).

Distributed voltage-driven demand response: flexibility, stability and value assessment
Creators: name: Guo, Jinrui
Publisher: name: Imperial College London
Year: 2020

description: The need for operating reserve from energy storage, demand reduction (DR) etc. is expected to increase signifcantly in future low-carbon Great Britain (GB) power system with high penetration of non-synchronous renewable generation. One way to provide the reserve is to use power electronic compensators (PECs) for point-of-load voltage control (PVC) to exploit the voltage dependence of loads. This thesis focuses on the quantifcation of DR capability from PVC in the domestic sector using high-resolution stochastic demand models and generic distribution networks in GB. The effectiveness of utilising PVC in contributing to frequency regulation is analysed and demonstrated through time domain simulations. The techno-economic feasibility of such technology is evaluated considering the investment cost of the PEC deployment as well as the economic and environmental benefts of using PVC. The payback period varies between 0.3 to 6.7 years for different future scenarios considering a range of converter price. It is demonstrated that PVC could effectively complement battery energy storage system towards enhanced frequency response provision in future GB power system. For practical application of PVC for ﬂexible demand and voltage regulation in future distribution networks/microgrids, it is important to investigate the overall small signal stability of the system. In this thesis, the linearised state space model of a distribution network/isolated microgrid with converter-interfaced distributed generators (CDGs) working in grid following mode along with loads with PVC is developed. The stability performance is revealed through both modal analysis and time domain simulations. It is shown that multiple loads with PVC for voltage regulation in distribution networks are not likely to threaten the small signal stability of the system. In the case of a microgrid, the introduction of PVC is shown to have marginal impact on the low frequency modes associated with the droop control of the CDGs. However, there is a trade-off when choosing the droop gain of the loads with PVC. Lower droop gains could ensure better frequency regulation in face of intermittent renewables but at the expense of a lower stability margin for an oscillation mode at a frequency slightly higher than 20Hz.
Investigating the role of nuclear encoded mitochondrial genes in the onset of type 2 diabetes
Creators: name: Maude, Hannah Elizabeth Billaux
Publisher: name: Imperial College London
Year: 2020

description: Mitochondrial dysfunction has long been implicated in Type 2 diabetes (T2D). This rela- tionship appears to be bidirectional, with evidence that mitochondrial dysfunction is both caused by and causal of T2D-related phenotypes. A potential causal role in T2D onset would be supported by evidence of a genetic predisposition to mitochondrial dysfunction, since inherited genetic risk factors precede and contribute to disease onset. Here, a genetic study design is used to investigate the potential role of T2D-associated genetic risk loci (T2D loci) in disrupting mitochondrial function through the altered expression of nuclear- encoded mitochondrial genes (NEMGs). The mitochondria are targeted by multiple T2D drugs and therefore such loci may be informative for effective treatment and prevention measures. The functional cis–genes regulated by T2D loci were identified based on the co-location of T2D loci with adipose tissue expression quantitative trait (eQTL) within a genetic distance of 1 LDU. T2D loci and eQTL were previously mapped using LDU- based gene mapping, which is compared and contrasted in this thesis to other popular tests of association. 50 of the identified T2D cis–genes were NEMGs and implicated a number of pathways in the inherited risk of T2D, including the relevant pathway of branched-chain amino acid catabolism. These same 50 genes were enriched for decreased expression in T2D cases compared to controls in independent gene expression datasets. Compared to the total known NEMGs, the 50 cis-NEMGs showed further enrichment for decreased expression, suggesting that T2D-eQTL co-location may identify specific subsets of causal genes. Finally, a candidate T2D locus associated with the cis–NEMG ACAD11 was fine-mapped using targeted sequence data for 94 T2D cases and 94 controls. Sev- eral candidate causal variants were identified, including two low-frequency haplotypes, one of which contained both an ACAD11 splicing mutation and a mutation predicted to disrupt the observed binding of HNF4A and COUP-TFII within the ACAD11 promoter region.

description: In the era of data-centric AI, the focus of recommender systems has shifted from model-centric innovations to data-centric approaches. The success of modern AI models is built on large-scale datasets, but this also results in significant training costs. Dataset distillation has emerged as a key solution, condensing large datasets to accelerate model training while preserving model performance. However, condensing discrete and sequentially correlated user-item interactions, particularly with extensive item sets, presents considerable challenges. This paper introduces \textbf{TD3}, a novel \textbf{T}ucker \textbf{D}ecomposition based \textbf{D}ataset \textbf{D}istillation method within a meta-learning framework, designed for sequential recommendation. TD3 distills a fully expressive \emph{synthetic sequence summary} from original data. To efficiently reduce computational complexity and extract refined latent patterns, Tucker decomposition decouples the summary into four factors: \emph{synthetic user latent factor}, \emph{temporal dynamics latent factor}, \emph{shared item latent factor}, and a \emph{relation core} that models their interconnections. Additionally, a surrogate objective in bi-level optimization is proposed to align feature spaces extracted from models trained on both original data and synthetic sequence summary beyond the naïve performance matching approach. In the \emph{inner-loop}, an augmentation technique allows the learner to closely fit the synthetic summary, ensuring an accurate update of it in the \emph{outer-loop}. To accelerate the optimization process and address long dependencies, RaT-BPTT is employed for bi-level optimization. Experiments and analyses on multiple public datasets have confirmed the superiority and cross-architecture generalizability of the proposed designs. Codes are released at https://github.com/USTC-StarTeam/TD3.

Supersymmetrizing Massive Gravity

description: When four scalar fields with global Lorentz symmetry are coupled to gravity and take a vacuum expectation value breaking diffeomorphism invariance spontaneously, the graviton becomes massive. This model is supersymmetrized by considering four N=1 chiral superfields with global Lorentz symmetry. When the scalar components of the chiral multiplets z^A acquire a vacuum expectation value, both diffeomorphism invariance and local supersymmetry are broken spontaneously. The global Lorentz index A becomes identified with the space-time Lorentz index making the scalar fields z^A vectors and the chiral spinors psi^A spin-3/2 Rarita-Schwinger fields. The global supersymmetry is promoted to a local one using the rules of tensor calculus of coupling the N=1 supergravity Lagrangian to the four chiral multiplets. We show that the spectrum of the model in the broken phase consists of a massive spin-2 field, two massive spin-3/2 fields with different mass and a massive vector.

description: Although highly effective on average, exposure-based treatments do not work equally well for all patients with anxiety disorders. The identification of pre-treatment response-predicting patient characteristics may enable patient stratification. Preliminary research highlights the relevance of inhibitory fronto-limbic networks as such. We aimed to identify pre-treatment neural signatures differing between exposure treatment responders and non-responders in spider phobia and to validate results through rigorous replication. Data of a bi-centric intervention study comprised clinical phenotyping and pre-treatment resting-state functional connectivity (rsFC) data of n  = 79 patients with spider phobia (discovery sample) and n  = 69 patients (replication sample). RsFC data analyses were accomplished using the Matlab-based CONN-toolbox with harmonized analyses protocols at both sites. Treatment response was defined by a reduction of >30% symptom severity from pre- to post-treatment (Spider Phobia Questionnaire Score, primary outcome). Secondary outcome was defined by a reduction of >50% in a Behavioral Avoidance Test (BAT). Mean within-session fear reduction functioned as a process measure for exposure. Compared to non-responders and pre-treatment, results in the discovery sample seemed to indicate that responders exhibited stronger negative connectivity between frontal and limbic structures and were characterized by heightened connectivity between the amygdala and ventral visual pathway regions. Patients exhibiting high within-session fear reduction showed stronger excitatory connectivity within the prefrontal cortex than patients with low within-session fear reduction. Whereas these results could be replicated by another team using the same data (cross-team replication), cross-site replication of the discovery sample findings in the independent replication sample was unsuccessful. Results seem to support negative fronto-limbic connectivity as promising ingredient to enhance response rates in specific phobia but lack sufficient replication. Further research is needed to obtain a valid basis for clinical decision-making and the development of individually tailored treatment options. Notably, future studies should regularly include replication approaches in their protocols.

description: Freshwater scarcity is a growing concern in Texas and the issues that surround it are expected to grow in the coming years. As climate change impacts the variability of precipitation patterns, some of the most useful tools to help allocate this precious, limited resource may be the tools that are most adaptable in the face of growing uncertainty. While market mechanisms are budding in the state, another market-based tool can create opportunities for efficient water allocation among stakeholders: the water option. An option is a financial product that provides a vehicle to interested parties (buyers and sellers) to create a contract that formalizes the terms of the possible future delivery of water. In cash markets for resources, the exchange of cash and the resource happens when the trade is made; in options markets, the flexibility of delivery is amplified considerably, making them useful for mitigating risk. The buyer of the contract is securing the right—not the obligation—to buy a specific amount of a resource, by a specific time, for a defined price and has the ability to decide if and when the contract gets exercised over the term of the contract. This work discusses the utility of these contracts and outlines a method to price them.

description: The galaxy cluster MACS J0717.5+3745 (z=0.55) is the largest known cosmic lens, with complex internal structures seen in deep X-ray, Sunyaev-Zel'dovich effect and dynamical observations. We perform a combined weak and strong lensing analysis with wide-field BVRi'z' Subaru/Suprime-Cam observations and 16-band Hubble Space Telescope observations taken as part of the Cluster Lensing And Supernova survey with Hubble (CLASH). We find consistent weak distortion and magnification measurements of background galaxies, and combine these signals to construct an optimally estimated radial mass profile of the cluster and its surrounding large-scale structure out to 5 Mpc/h. We find consistency between strong-lensing and weak-lensing in the region where these independent data overlap, <500 kpc/h. The two-dimensional weak-lensing map reveals a clear filamentary structure traced by distinct mass halos. We model the lensing shear field with 9 halos, including the main cluster, corresponding to mass peaks detected above 2.5σ_κ. The total mass of the cluster as determined by the different methods is M_{vir}=(2.8\pm0.4) \times 10^15 M_sun. Although this is the most massive cluster known at z>0.5, in terms of extreme value statistics we conclude that the mass of MACS J0717.5+3745 by itself is not in serious tension with LambdaCDM, representing only a ~2σ departure above the maximum simulated halo mass at this redshift.

description: We show that near a quantum critical point generating quantum criticality of strongly correlated metals where the density of electron states diverges, the quasi-classical physics remains applicable to the description of the resistivity ρof strongly correlated metals due to the presence of a transverse zero-sound collective mode, reminiscent of the phonon mode in solids. We demonstrate that at T, being in excess of an extremely low Debye temperature T_D, the resistivity ρ(T) changes linearly with T, since the mechanism, forming the T dependence of ρ(T), is the same as the electron-phonon mechanism that prevails at high temperatures in ordinary metals. Thus, electron-phonon scattering leads to near material-independence of the lifetime τof quasiparticles that is expressed as the ratio of the Planck constant \hbar to the Boltzmann constant k_B, Tτ\sim \hbar/k_B. We find that at T

description: The Proca-Corben-Schwinger equations for a spin-1 particle with an anomalous magnetic moment are added by a term describing an electric dipole moment, then they are reduced to a Hamiltonian form, and finally they are brought to the Foldy-Wouthuysen representation. Relativistic equations of motion are derived. The needed agreement between quantum-mechanical and classical relativistic equations of motion is proved. The scalar and tensor electric and magnetic polarizabilities of pointlike spin-1 particles (W bosons) are calculated for the first time.

description: We introduce a simple model to self-consistently connect the growth of galaxies to the formation history of their host dark matter haloes. Our model is defined by two simple functions: the "baryonic growth function" which controls the rate at which new baryonic material is made available for star formation, and the "physics function" which controls the efficiency with which this material is converted into stars. Using simple, phenomenologically motivated forms for both functions that depend only on a single halo property, we demonstrate the model's ability to reproduce the z=0 red and blue stellar mass functions. Furthermore, by adding redshift as a second input variable to the physics function we show that the reproduction of the global stellar mass function out to z=3 is improved. We conclude by discussing the general utility of our new model, highlighting its usefulness for creating mock galaxy samples which have a number of key advantages over those generated by other techniques.

description: Η συνεχώς αυξανόμενη παραγωγή αστικών αποβλήτων και οι αρνητικές επιπτώσεις αυτών στο περιβάλλον, καθώς και η αναζήτηση νέων ανανεώσιμων πηγών ενέργειας, δημιουργούν την ανάγκη αξιοποίησης τους. Η τεχνολογία της καύσης χρησιμοποιείται για την ανάκτηση ενέργειας από ιλύ λυμάτων και από αστικά στερεά απόβλητα. Ωστόσο, η παραγωγή τέφρας κατά την διεργασία αυτή απαιτεί σωστή διαχείριση για την αποφυγή περιβαλλοντικών επιπτώσεων που προκαλούνται κατά την απόθεσή της στο έδαφος.
Στην παρούσα μεταπτυχιακή διατριβή χρησιμοποιήθηκαν τέφρες από λυματολάσπη(ΛΛ), πυρηνόξυλο(ΠΞ), αστικά στερεά απόβλητα(ΑΣΑ) και μείγματα αυτών, έπειτα από καύση σε στερεά/ρευστοποιημένη κλίνη. Για την σταθεροποίηση των βαρέων μετάλλων των τεφρών κατά την έκπλυσή τους μέσω εδάφους χρησιμοποιήθηκαν ως σταθεροποιητές ιπτάμενη τέφρα ΑΗΣ Μελίτης(ΙΤ), ″silica fume‶(SiO2) και τέφρα άχυρου σίτου(ΑΣ).
Αρχικά, πραγματοποιήθηκαν εκπλύσεις των τεφρών μέσω του εδάφους και στην συνέχεια με την προσθήκη σταθεροποιητών σε διάφορες αναλογίες. Στα υδατικά εκπλύματα που προέκυψαν υπολογίστηκαν το pH, η ηλεκτρική αγωγιμότητα, τα κύρια ανόργανα στοιχεία και ιχνοστοιχεία και η συγκέντρωση των ιόντων χλωρίου, θείου και φωσφόρου.
Γενικά, παρατηρήθηκε συγκράτηση της πλειοψηφίας των στοιχείων στο δείγμα της τέφρας ΠΞ/ΑΣΑ 90:10 με την προσθήκη των σταθεροποιητών κατά την έκπλυση από το έδαφος. Για ποσοστό 10% σταθεροποιητών καταγράφηκε μείωση του ποσοστού έκπλυσης όλων των ιχνοστοιχείων, ενώ όταν χρησιμοποιήθηκε το μείγμα των σταθεροποιητών σε ποσοστό 10% έκαστο, η μείωση έκπλυσης των ιχνοστοιχείων ήταν υψηλότερη. Για ποσοστό σταθεροποιητών 20%, η μείωση των ιχνοστοιχείων συνεχίστηκε έως και 100% για όλα τα ιχνοστοιχεία, εκτός του Sr, το οποίο είχε πολύ χαμηλές τιμές και του Cr, το οποίο όμως παρουσίασε ιδιαίτερη μείωση από 76% έως και 89%.

description: We report on many-body corrections to one-electron energy spectra of bulk bismuth tellurohalides---materials that exhibit a giant Rashba-type spin splitting of the band-gap edge states. We show that the corrections obtained in the one-shot $GW$ approximation noticeably modify the spin-orbit-induced spin splitting evaluated within density functional theory. We demonstrate that taking into account many-body effects is crucial to interpret the available experimental data.

description: We report the experimental violation of Leggett-type inequalities for a hybrid entangled state of spin and orbital angular momentum of a single photon. These inequalities give a physical criterion to verify the possible validity of a class of hidden-variable theories, originally named "crypto non-local", that are not excluded by the violation of Bell-type inequalities. In our case, the tested theories assume the existence of hidden variables associated with independent degrees of freedom of the same particle, while admitting the possibility of an influence between the two measurements, i.e. the so-called contextuality of observables. We observe a violation the Leggett inequalities for a range of experimental inputs, with a maximum violation of seven standard deviations, thus ruling out this class of hidden variable models with a high confidence.

description: The Hamamatsu R11410 photomultiplier, a tube of 3" diameter and with a very low intrinsic radioactivity, is an interesting light sensor candidate for future experiments using liquid xenon (LXe) as target for direct dark matter searches. We have performed several experiments with the R11410 with the goal of testing its performance in environments similar to a dark matter detector setup. In particular, we examined its long-term behavior and stability in LXe and its response in various electric field configurations.

description: Ion channels are critical in enabling ion movement into and within cells and are important targets for pharmacological interventions in different human diseases. In addition to their ion transport abilities, ion channels interact with signalling and scaffolding proteins, which affects their function, cellular positioning, and links to intracellular signalling pathways. The study of “channelosomes” within cells has the potential to uncover their involvement in human diseases, although this field of research is still emerging. LRRC8A is the gene that encodes a crucial protein involved in the formation of volume-regulated anion channels (VRACs). Some studies suggest that LRRC8A could be a valuable prognostic tool in different types of cancer, serving as a biomarker for predicting patients’ outcomes. LRRC8A expression levels might be linked to tumour progression, metastasis, and treatment response, although its implications in different cancer types can be varied. Here, publicly accessible databases of cancer patients were systematically analysed to determine if a correlation between VRAC channel expression and survival rate exists across distinct cancer types. Moreover, we re-evaluated the impact of LRRC8A on cellular proliferation and migration in colon cancer via HCT116 LRRC8A-KO cells, which is a current topic of debate in the literature. In addition, to investigate the role of LRRC8A in cellular signalling, we conducted biotin proximity-dependent identification (BioID) analysis, revealing a correlation between VRAC channels and cell-cell junctions, mechanisms that govern cellular calcium homeostasis, kinases, and GTPase signalling. Overall, this dataset improves our understanding of LRRC8A/VRAC and explores new research avenues while identifying promising therapeutic targets and promoting inventive methods for disease treatment.
