description: Covert channels can be used to circumvent system and network policies by establishing communications that have not been considered in the design of the computing system. We construct a covert channel between different computing systems that utilizes audio modulation/demodulation to exchange data between the computing systems over the air medium. The underlying network stack is based on a communication system that was originally designed for robust underwater communication. We adapt the communication system to implement covert and stealthy communications by utilizing the ultrasonic frequency range. We further demonstrate how the scenario of covert acoustical communication over the air medium can be extended to multi-hop communications and even to wireless mesh networks. A covert acoustical mesh network can be conceived as a meshed botnet or malnet that is accessible via inaudible audio transmissions. Different applications of covert acoustical mesh networks are presented, including the use for remote keylogging over multiple hops. It is shown that the concept of a covert acoustical mesh network renders many conventional security concepts useless, as acoustical communications are usually not considered. Finally, countermeasures against covert acoustical mesh networks are discussed, including the use of lowpass filtering in computing systems and a host-based intrusion detection system for analyzing audio input and output in order to detect any irregularities.

description: The teacher attrition at the beginning of the teaching career has aggravated the shortage of teachers in some countries. We carried out a case study of a novice physics teacher working in two Brazilian schools. Based on the Cultural-Historical Activity Theory, we analyzed the contradictions that emerged and how they transformed his teaching activity. The analysis indicates that the central contradiction, which emerged from how the capitalist modes of educational work are structured, determined an increasing teacher's work alienation, reinforcing his fear of losing his job.

description: The evolution and fate of very massive stars (VMS) is tightly connected to their mass-loss properties. Their initial and final masses differ significantly as a result of mass loss. VMS have strong stellar winds and extremely high ionising fluxes, which are thought to be critical sources of both mechanical and radiative feedback in giant Hii regions. However, how VMS mass-loss properties change during stellar evolution is poorly understood. In the framework of the VLT-Flames Tarantula Survey (VFTS), we explore the mass-loss transition region from optically thin O to denser WNh star winds, thereby testing theoretical predictions. To this purpose we select 62 O, Of, Of/WN, and WNh stars, an unprecedented sample of stars with the highest masses and luminosities known. We perform a spectral analysis of optical VFTS as well as near-infrared VLT/SINFONI data using the non-LTE radiative transfer code CMFGEN to obtain stellar and wind parameters. For the first time, we observationally resolve the transition between optically thin O and optically thick WNh star winds. Our results suggest the existence of a kink between both mass-loss regimes, in agreement with recent MC simulations. For the optically thick regime, we confirm the steep dependence on the Eddington factor from previous theoretical and observational studies. The transition occurs on the MS near a luminosity of 10^6.1Lsun, or a mass of 80...90Msun. Above this limit, we find that - even when accounting for moderate wind clumping (with f = 0.1) - wind mass-loss rates are enhanced with respect to standard prescriptions currently adopted in stellar evolution calculations. We also show that this results in substantial helium surface enrichment. Based on our spectroscopic analyses, we are able to provide the most accurate ionising fluxes for VMS known to date, confirming the pivotal role of VMS in ionising and shaping their environments.

description: In the present study, commercial cocoa powders with different cocoa fat contents were studied. It was found that the cocoa powders’ flow patterns were of a cohesive to highly cohesive characters. It was demonstrated, that the powders of higher crystalline structure were less flowable compared to the ones with the more amorphous ones. It was observed by SEM that the studied cocoa powders of higher cocoa fat content and the ones with the dietary fibers content (sample 2) exhibited more amorphous structure. The predominantly smooth surface structure of the higher fat content cocoa powder allowed its higher dense packing, triggering the decreased sound absorption typical for non-porous materials as quantified by NRC of 0.289 (sample 1, 100 mm material height) and 0.227 (sample 3) to 0.182 (sample 2). The latter conclusions were also supported by the observed increase of the structural mechanical stiffness of the freely poured powder bed of high cocoa fat amorphous powders, as resulting in the increasing magnitude of the Kl of 12.83 MPa (sample 1, 100 mm material height) and 19.29 MPa (sample 3) to 37.82 MPa (sample 2). Melting temperatures of the samples were determined by DSC. Results were directly corresponded to the cocoa butter content. The highest enthalpy of fusion (ΔHm) of (23.32 ± 0.21) J/g was obtained for the highest cocoa butter containing sample 2 (of 20–22 wt. %). Obtained values of ΔHm for samples 1 and 2 were of (12.38 ± 0.20) J/g and (10.27 ± 0.17) J/g. Tp (melt) for reversing heat flow was ranging from (30.16 ± 0.10) °C to (32.28 ± 0.10) °C indicating the melting of stable β polymorph. The melting peaks observed at distinct temperatures in the non-reversing heat flow patterns were indicating melting of the unstable α and metastable β’ and stable β cocoa butter polymorphic forms.

description: Introduction: Non-Alcoholic Fatty Liver Disease encompasses a spectrum of diseases ranging from simple steatosis to steatohepatitis (or NASH), up to cirrhosis and hepatocellular carcinoma(HCC). The challenge is to recognize the more severe and/or progressive pathology. A reliable non-invasive method does not exist. Untargeted metabolomics is a novel method to discover biomarkers and give insights on diseases pathophysiology. Objectives: we applied metabolomics to understand if simple steatosis, steatohepatitis and cirrhosis in NAFLD patients have peculiar metabolites profiles that can differentiate them among each-others and from controls. Methods: Metabolomics signatures were obtained from 307 subjects from two separated enrollments. The first collected samples from 69 controls and 144 patients (78 steatosis, 23 NASH, 15 NASH-cirrhosis, 8 HCV-cirrhosis, 20 cryptogenic cirrhosis). The second, used as validation-set, enrolled 44 controls and 50 patients (34 steatosis, 10 NASH and 6 NASH-cirrhosis). The “Partial-Least-Square Discriminant-Analysis” (PLS-DA) was used to reveal class separation in metabolomics profiles between patients and controls and among each class of patients, and to reveal the metabolites contributing to class differentiation. Results: Several metabolites were selected as relevant, in particular: Glycocholic acid, Taurocholic acid, Phenylalanine, branched-chain amino acids increased at the increase of the severity of the disease from steatosis to NASH, NASH-cirrhosis, while glutathione decreased (p<0.001 for each). Moreover, an ensemble machine learning (EML) model was built using 10 different classification models. EML showed accuracy>80% in NAFLD evolution steps prediction. Conclusions: Metabolomics profiles of NAFLD patients could be a useful tool to non-invasively diagnose NAFLD and discriminate among the various stages of the disease, giving insights into its pathophysiology.

description: Ce travail de recherche s’inscrit dans le cadre de notre mémoire de Bachelor en enseignement préscolaire et primaire, à la HEP de Lausanne. Nous nous sommes intéressées à la manière dont il était possible d’améliorer le rapport aux mots des élèves, car dans la plupart des cas l’apprentissage du vocabulaire est souvent perçu comme étant une « corvée » pour les élèves. Afin de pallier cette perception, nous proposons une séquence d’enseignement sur un apprentissage spécifique autour de la devinette et des mots polysémiques. Cette recherche est un défi que nous nous sommes lancé, car la devinette impliquant de travailler les mots polysémiques est un genre qui est normalement travaillé au cycle 2. Ce mémoire s’articulera à travers divers chapitres. Tout d’abord, les points-clés théoriques nécessaires à la compréhension de notre recherche seront présentés. Ensuite, nous justifierons notre choix concernant la question de recherche, pour passer à la méthodologie qui présentera en détail la séquence que nous avons mise en place et la manière dont elle a été mise en œuvre. Les données que nous avons récoltées ont été analysées, questionnées et comparées entre les deux classes. Pour finir, nous avons fait ressortir les limites de cette recherche et de la mise en place de la séquence.

description: We fabricate a graphene p-n-p heterojunction and exploit the coherence of weakly-confined Dirac quasiparticles to resolve the underlying scattering potential using low temperature scanning gate microscopy. The tip-induced perturbation to the heterojunction modifies the condition for resonant scattering, enabling us to detect localized Fabry-Perot cavities from the focal point of halos in scanning gate images. In addition to halos over the bulk we also observe ones spatially registered to the physical edge of the graphene. Guided by quantum transport simulations we attribute these to modified resonant scattering at the edges within elongated cavities that form due to focusing of the electrostatic field.

description: Aquatic by-products during fish processing cause environmental pollution and increase disposal costs. Cuttlefish skin is one of the major by-products of cuttlefish (Sepia pharaonis) processing and is generally thrown as a by-product. It can cause severe environmental problems and odor. It has been discovered that cuttlefish skin can be an excellent resource for producing attractive amounts of collagen. This study optimized collagen extraction conditions using response surface methodology (RSM). In addition, SDS-PAGE, specific charge, and scanning electron microscopy (SEM) characteristics of extracted collagen were evaluated. The results showed that the optimal extraction conditions for cuttlefish skin collagen are pH 1.5, 20 mg/L (solid-liquid ratio), 15 U/mg (Pepsin), and the average extraction rate can be obtained as 8.79%. The results of LC/MS/MS analysis of the collagen samples extracted in this study showed that the main m/z signal of proline produced by mass spectrometry was between 2000–4000. Collagen extracted from the cuttlefish skin is type I collagen, which consists of 2 α chains and 1 β chain (α2, α1, β). SEM analysis of collagen confirmed the presence of collagen fibrils in the cuttlefish skin similar to previous reports. Using the response surface methodology, optimal collagen extraction conditions pH 1.5, 20 mg/L (solid-liquid ratio), and 15 U/mg (Pepsin) can be obtained to recycle and utilize by-products.

description: Notre travail de Bachelor porte sur la collaboration école-familles multiculturelles, plus précisément, sur les attentes réciproques des enseignants et des parents. Dans le canton de Vaud, l’école accueille de plus en plus de familles multiculturelles. L’enjeu des enseignants est de collaborer avec ces familles afin d’inclure au mieux tous les enfants. Cependant, une tension se crée entre la volonté de collaborer et les difficultés pour les parents de se sentir partenaires de l’école. Certaines discordes peuvent également apparaître entre la culture familiale et la culture scolaire. Cette recherche se base sur une méthode qualitative, sous forme d’entretiens semi-directifs à l’aide d’un canevas de questions basé sur différentes thématiques étudiées dans notre cadre théorique. Les principaux concepts ont été la culture familiale / la culture scolaire, la collaboration et les attentes réciproques. Les thèmes que nous avons également définis sont les facilitateurs/ obstacles à la collaboration, les objectifs communs, les dispositifs mis en place pour collaborer, l’investissement, les rôles, les limites et les impacts de la culture sur la collaboration entre les enseignants et les parents. Deux parents, ainsi que deux enseignants de différentes régions du canton de Vaud, ont accepté de participer à la recherche, afin de procéder aux entretiens. Grâce à la récolte de données durant les entretiens ainsi qu’aux représentations des participants, nous avons pu répondre à notre question de recherche : “Quelles attentes réciproques ont les enseignants et les familles multiculturelles au sein de leur collaboration dans le canton de Vaud ?”. Les résultats relèvent que la collaboration est essentielle pour l’école et les familles afin d’aider au mieux l’élève dans sa scolarité. Les enseignants considèrent leur collaboration au même niveau pour toutes les familles. Par ailleurs, certains facilitateurs à la collaboration ont pu être identifiés comme la communication, l’investissement réciproque. D’un autre côté, certains obstacles peuvent également apparaître comme le manque de communication ou les incompréhensions.

description: In this work we review the application of the theory of Gaussian processes to the modeling of noise in pulsar-timing data analysis, and we derive various useful and optimized representations for the likelihood expressions that are needed in Bayesian inference on pulsar-timing-array datasets. The resulting viewpoint and formalism lead us to two improved parameter-sampling schemes inspired by Gibbs sampling. The new schemes have vastly lower chain autocorrelation lengths than the Markov Chain Monte Carlo methods currently used in pulsar-timing data analysis, potentially speeding up Bayesian inference by orders of magnitude. The new schemes can be used for a full-noise-model analysis of the large datasets assembled by the International Pulsar Timing Array collaboration, which present a serious computational challenge to existing methods.

description: Extracting colorimetric image information from the spectral characteristics of image sensors is a key issue in accurate image acquisition. Technically feasible filter/sensor combinations usually do not replicate colorimetric responses with sufficient accuracy to be directly applicable to color representation. A variety of transformations have been proposed in the literature to compensate for this. However, most of those rely on heuristics and/or introduce a reconstruction dependent on the composition of the incoming illumination. In this work, we present a spectral reconstruction method that is independent of illumination and is derived in a mathematically strict way. It provides a deterministic method to arrive at a least mean squared error approximation of a target spectral characteristic from arbitrary sensor response curves. Further, we present a new CMOS sensor design in a standard digital 65nm CMOS technology. Novel circuit techniques are used to achieve performance comparable with much larger-sized specialized photo-CMOS processes. The sensor is utilized as testbed for the spectral reconstruction method.

description: Management of PCI patients undergoing early surgery is still a matter of debate. Noteworthy, PCI patients require a dual antiplatelet therapy (DAPT), with aspirine and a thienopiridine (clopidogrel, prasugrel, ticagrelor), because of the high risk of stent thrombosis (ST), myocardial infarction (MI) and death, especially within the first month. Indeed, the number of surgical interventions after PCI is actually increasing, and physicians are looking for the best antiplatelet therapy management, in order to reduce both, bleeding and thrombosis risk. In this paper, current guidelines therapy management and new optional strategies to reduce the cardiovascular risk, related to early surgery, are discussed.

description: We build a tractable New Keynesian model to study four types of monetary and fiscal policy.
We find that quantitative easing (QE), lump-sum fiscal transfers, and government spending
have the same effects on the aggregate economy when fiscal policy is fully tax financed.
Compared with these three policies, conventional monetary policy is more inflationary for the
same amount of stimulus. QE and transfers have redistribution consequences, whereas
government spending and conventional monetary policy do not. Ricardian equivalence breaks
down: tax-financed fiscal policy is more stimulative than debt-financed policy. Finally, we study
optimal policy coordination and find that adjusting two types of policy instruments—the policy
rate together with QE or fiscal transfers—can stabilize three targets simultaneously: inflation,
the aggregate output gap, and cross-sectional consumption dispersion.
description: Nous construisons un modèle néo-keynésien résoluble pour étudier quatre types de politique
monétaire et budgétaire. Nous constatons que l’assouplissement quantitatif, les transferts
budgétaires forfaitaires et les dépenses publiques ont les mêmes effets sur l’ensemble de
l’économie lorsque la politique budgétaire est entièrement financée par les recettes fiscales.
Comparativement à ces trois politiques, la politique monétaire traditionnelle est plus
inflationniste pour le même degré de détente. L’assouplissement quantitatif et les transferts
ont des effets de redistribution, mais pas les dépenses publiques ni la politique monétaire
traditionnelle. Dans notre modèle, l’hypothèse de l’équivalence ricardienne ne tient pas, car la
politique budgétaire financée par les recettes fiscales est plus expansionniste que la politique
financée par l’emprunt. Enfin, nous nous penchons sur la coordination optimale des politiques
et notons que le fait d’ajuster deux types d’instruments d’intervention – le taux directeur jumelé
à l’assouplissement quantitatif ou aux transferts budgétaires – peut stabiliser trois cibles à la
fois : l’inflation, l’écart de production globale et la dispersion transversale de la consommation

description: This thesis is a qualitative study of the major societal institutions' social media policies. Three features are compared-length, readability, and legal orientation and punitive degree-in order to determine the homogeneity of the policies across the institutional categories. The top ten words featured in the policies, from highest weighted percentage to lowest, are the following: social, use, media, post, sites, content, personal, policy, communication, and web. The shortest policy length was 274 words. The longest policy was 36,036 words and the collective average word count was 2,571. The lowest reading level, based on the Gunning Fog Readability Index was 8.21, the highest was 21. 97, and the collective average was 12.31. Finally, there was a high reference rate to the word "law" and its synonyms and the policies used "prohibit" more than "discourage."

description: We combine Spitzer $3.6μ$ observations of a sample of disk galaxies spanning over 10 magnitudes in luminosity with optical luminosities and colors to test population synthesis prescriptions for computing stellar mass. Many commonly employed models fail to provide self-consistent results: the stellar mass estimated from the luminosity in one band can differ grossly from that of another band for the same galaxy. Independent models agree closely in the optical ($V$-band), but diverge at longer wavelengths. This effect is particularly pronounced in recent models with substantial contributions from TP-AGB stars. We provide revised color--mass-to-light ratio relations that yield self-consistent stellar masses when applied to real galaxies. The $B-V$ color is a good indicator of the mass-to-light ratio. Some additional information is provided by $V-I$, but neither it nor $J-K_s$ are particularly useful for constraining the mass-to-light ratio on their own. In the near-infrared, the mass-to-light ratio depends weakly on color, with typical values of $0.6\; \mathrm{M}_{\odot}/\mathrm{L}_{\odot}$ in the $K_s$-band and $0.47\; \mathrm{M}_{\odot}/\mathrm{L}_{\odot}$ at $3.6μ$.

description: We present a free form mass reconstruction of the massive lensing cluster MACSJ0416.1-2403 using the latest Hubble Frontier Fields data. Our model independent method finds that the extended lensing pattern is generated by two elongated, closely projected clusters of similar mass. Our lens model identifies new lensed images with which we improve the accuracy of the dark matter distribution. We find that the bimodal mass distribution is nearly coincident with the bimodal X-ray emission, but with the two dark matter peaks lying closer together than the centroids of the X-ray emisison. We show this can be achieved if the collision has occurred close to the plane and such that the cores are deflected around each other. The projected mass profiles of both clusters are well constrained because of the many interior lensed images, leading to surprisingly flat mass profiles of both components in the region 15-100 kpc. We discuss the extent to which this may be generated by tidal forces in our dynamical model which are large during an encounter of this type as the cores "graze" each other. The relative velocity between the two cores is estimated to be about 1200 km/s and mostly along the line of sight so that our model is consistent with the relative redshift difference between the two cD galaxies (dz = 0.04).

description: Εισαγωγή: Τα πολυπύρηνα γιγαντοκύτταρα ανευρίσκονται σε υπερπλαστικές, φλεγμονώδεις και νεοπλασματικές παθήσεις του θυρεοειδούς αδένα, όπως είναι οι θυρεοειδίτιδες, το θηλώδες καρκίνωμα και οι κοκκιωματώδεις καταστάσεις του θυρεοειδούς. Η ιστολογική εικόνα του θυρεοειδούς αδένα σε ασθενείς με χρονία θυρεοειδίτιδα ποικίλλει σημαντικά. Λίγες μελέτες όμως έχουν επικεντρωθεί στη συσχέτιση της ιστολογικής εικόνας με τη θυρεοειδική λειτουργία στη χρονία θυρεοειδίτιδα. Σκοπός: Σκοπός αυτής της μελέτης είναι να περιγράφει τα μορφολογικά χαρακτηριστικά των πολυπύρηνων γιγαντοκυττάρων του θυρεοειδούς αδένα, τον αριθμό των πυρήνων τους και τη συχνότητα εμφάνισής τους στις διάφορες παθήσεις του θυρεοειδούς. Επίσης μελετάει τη συσχέτιση της θυρεοειδικής λειτουργίας με την ιστολογική εικόνα στη χρονία θυρεοειδίτιδα. Υλικό και μέθοδος: Τετρακόσιοι ασθενείς ( 400 ) συμμετείχαν σε αυτή τη μελέτη. Κυτταρολογικά επιχρίσματα ελήφθησαν, με τη μέθοδο της αναρροφητικής βιοψίας δια λεπτής βελόνης. Οι ασθενείς επελέγησαν με την προϋπόθεση να εμφανίζουν μακροφάγα κύτταρα στα κυτταρολογικά επιχρίσματα του θυρεοειδούς αδένα. Στους ασθενείς πραγματοποιήθηκε αιμοληψία, με σκοπό τη μέτρηση των θυρεοειδικών ορμονών και ο ορός φυλάχτηκε σε θερμοκρασία -20 βαθμών Κελσίου. Μελετήθηκε η μορφολογία των πολυπύρηνων γιγαντοκυττάρων και ο αριθμός των πυρήνων τους καθώς και το ιατρικό ιστορικό των ασθενών που μετείχαν στη μελέτη. Αποτελέσματα: Τα πολυπύρηνα γιγαντοκύτταρα στην καλοήθη οζώδη βρογχοκήλη ήταν μικρά, είχαν ωοειδές σχήμα, αφρώδες κυτταρόπλασμα και μικρό αριθμό πυρήνων. Αντίθετα, στον καρκίνο του θυρεοειδούς, τα πολυπύρηνα γιγαντοκύτταρα εμφάνιζαν ακανόνιστο μέγεθος, σχήμα, παρουσίαζαν πυκνό κυτταρόπλασμα και μεγάλο αριθμό πυρήνων. Στον πληθυσμό που μελετήσαμε η πλειοψηφία των ασθενών εμφάνιζε καλοήθη οζώδη βρογχοκήλη και θυρεοειδίτιδα. Η ιστολογική εικόνα της χρονιάς θυρεοειδίτιδας ταξινομήθηκε σε τέσσερις ομάδες : οξυφιλική, μικτή, εστιακή και υπερπλαστική, ενώ η θυρεοειδική λειτουργία, με βάση τα επίπεδα των θυρεοειδικών ορμονών και το ιστορικό του ασθενούς, σε ευθυρεοειδική, υποθυρεοειδική και υπερθυρεοειδική. Η πλειονότης των ασθενών στην οξυφιλική ομάδα ήταν υποθυρεοειδικοί, στην εστιακή ομάδα ήταν ευθυρεοειδικοί, στην υπερπλαστική ομάδα υπερθυρεοειδικοί ενώ στη μικτή ομάδα δεν παρατηρήθηκε υπεροχή κάποιας κλινικής οντότητας. Συμπεράσματα: Η παρουσία μεγάλων πολυπύρηνων γιγαντοκυττάρων με πυκνό κυτταρόπλασμα και μεγάλο αριθμό πυρήνων σε ένα θυρεοειδικό όζο, όταν δεν υπάρχει υποψία θυρεοειδίτιδας, στρέφει τη διάγνωση προς τον θυρεοειδικό καρκίνο. Η ιστολογική ταξινόμηση της χρονιάς θυρεοειδίτιδας μπορεί να αποδειχθεί χρήσιμη στην πρόβλεψη της θυρεοειδικής λειτουργίας. Η αναρροφητική βιοψία δια λεπτής βελόνης αποτελεί χρήσιμο διαγνωστικό εργαλείο για την αιτιολογική διερεύνηση του υπέρ ή υποθυρεοειδισμού.

description: Launched in 2006 and officially founded as an ERIC (European Research Infrastructure Consortium) in 2014, DARIAH has long held a place in the SSH Research Landscape. These first years were focused more on the construction of our international research infrastructure and of the various national consortia, as well as policy and advocacy on behalf of our communities. DARIAH also served, and continues to serve, as an excellent incubator for European project grants and the creation of project consortia. In the last two years, however, DARIAH has reached a new phase of maturity, with better organizational processes, developed services, and a stronger network of humanities researchers across Europe and beyond. These efforts are headlined notably by the SSH Open Marketplace and DARIAH Campus platforms, discovery platforms for tools and services, and pedagogical materials, respectively. Joining with the existing, grassroots and researcher-led Working Groups, DARIAH now has multiple means of enabling research in social sciences and humanities in a way that is visible to the individual researcher. DARIAH’s evolution presents an interesting use case in building a digital research infrastructure on a European scale, showing how to put in place infrastructural components and know-how to help advance the cause of SSH research in an increasingly digital and changing research landscape.

Localization in a spanwise-extended model of plane Couette flow

Year: 2014
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: We consider a 9-PDE (1-space and 1-time) model of plane Couette flow in which the degrees of freedom are severely restricted in the streamwise and cross-stream directions to study spanwise localisation in detail. Of the many steady Eckhaus (spanwise modulational) instabilities identified of global steady states, none lead to a localized state. Localized periodic solutions were found instead which arise in saddle node bifurcations in the Reynolds number. These solutions appear global (domain filling) in narrow (small spanwise) domains yet can be smoothly continued out to fully spanwise-localised states in very wide domains. This smooth localisation behaviour, which has also been seen in fully-resolved duct flow (Okino 2011), indicates that an apparently global flow structure needn't have to suffer a modulational instability to localize in wide domains.

description: The organic conductor $κ$-(BEDT-TTF)$_2$Cu$_2$(CN)$_{3}$ seems to form a quantum spin liquid, although at low temperatures unusual properties are seen in the charge, spin and lattice degrees of freedom. Here we report results of X-band ESR studies of $κ$-(BEDT-TTF)$_2$Cu$_2$(CN)$_{3}$ single crystals as a function of temperature and angle. We find indications of two anisotropic relaxation mechanisms at low temperatures and compare them to the spin-liquid behavior observed in other strongly correlated systems. In addition, we can recognize charge inhomogeneities in the copper ions of the anion layer. This disorder might be linked to the dielectric response measured in this compound.
