description: This paper treats absorption problems for the one-dimensional quantum walk determined by a 2 times 2 unitary matrix U on a state space {0,1,...,N} where N is finite or infinite by using a new path integral approach based on an orthonormal basis P, Q, R and S of the vector space of complex 2 times 2 matrices. Our method studied here is a natural extension of the approach in the classical random walk.

description: Biomolecular assembly processes based on liquid–liquid phase separation (LLPS) are ubiquitous in the biological cell. To fully understand the role of LLPS in biological self-assembly, it is necessary to characterize also their kinetics of formation and dissolution. Here, we introduce the pressure-jump relaxation technique in concert with UV/Vis and FTIR spectroscopy as well as light microscopy to characterize the evolution of LLPS formation and dissolution in a time-dependent manner. As a model system undergoing LLPS we used the globular eye-lens protein γD-crystallin. As cosolutes and macromolecular crowding are known to affect the stability and dynamics of biomolecular condensates in cellulo, we extended our kinetic study by addressing also the impact of urea, the deep-sea osmolyte trimethylamine-N-oxide (TMAO) and a crowding agent on the transformation kinetics of the LLPS system. As a prerequisite for the kinetic studies, the phase diagram of γD-crystallin at the different solution conditions also had to be determined. The formation of the droplet phase was found to be a very rapid process and can be switched on and off on the 1–4 s timescale. Theoretical treatment using the Johnson–Mehl–Avrami–Kolmogorov model indicates that the LLPS proceeds via a diffusion-limited nucleation and growth mechanism at subcritical protein concentrations, a scenario which is also expected to prevail within biologically relevant crowded systems. Compared to the marked effect the cosolutes take on the stability of the LLPS region, their effect at biologically relevant concentrations on the phase transformation kinetics is very small, which might be a particular advantage in the cellular context, as a fast switching capability of the transition should not be compromised by the presence of cellular cosolutes.

description: Atomic structure and electronic band structure are fundamental properties for understanding the mechanism of superconductivity. Motivated by the discovery of pressure-induced high-temperature superconductivity at 80 K in the bilayer Ruddlesden-Popper nickelate La3Ni2O7, the atomic structure and electronic band structure of the trilayer nickelate La4Ni3O10 under pressure up to 44.3 GPa are investigated. A structural transition from the monoclinic P21/a space group to the tetragonal I4/mmm around 12.6-13.4 GPa is identified, accompanying with a drop of resistance below 7 K. Density functional theory calculations suggest that the bonding state of Ni 3dz2 orbital rises and crosses the Fermi level at high pressures, which may give rise to possible superconductivity observed in resistance under pressure in La4Ni3O10. The trilayer nickelate La4Ni3O10 shows some similarities with the bilayer La3Ni2O7 and has unique properties, providing a new platform to investigate the underlying mechanism of superconductivity in nickelates.

They are versions of $U_q(su_{n+1})$ with a fermionic rather than bosonic quantum plane of roots adjoined to $U_q(su_n)$. We give the $n=2$ case in detail. We also consider the anyonic-double of an anyonic ($Z/nZ$-graded) braided group and the double-bosonisation of the free braided group in $n$ variables.

Deconstructing Discourse: Gender and Neoliberal Orientalism in the Egyptian Revolution

description: This thesis will show that in Egyptian media and political discourse, women’s rights rhetoric serves as a façade for anti-woman nationalism, and in American media and political discourse, neoliberal support for the revolution cloaks gendered orientalism. Each is riddled with contradictions. The juxtaposition of appropriating a pro-woman label while dismissing its substance, with the dismissal of a racist concept’s label yet utilization of its substance demonstrates a grave problem in both political activism and media: indifference to probing reflection and the prioritization of a means-to-an-end attitude. This indifference and these priorities only produce short-term or surface-level solutions because they employ short-term and surface-level tactics. Consequently, revolutions do not result in the desperately desired deconstruction of hegemonic political, economic and social systems, and media does not yield in-depth investigations into the systemic problems in which the issues discussed are rooted.
Measurement of differential cross sections and charge ratios for $t$-channel single top quark production in proton-proton collisions at $\sqrt{s} =$ 13 TeV

description: A measurement is presented of differential cross sections for $t$-channel single top quark and antiquark production in proton-proton collisions at a centre-of-mass energy of 13 TeV by the CMS experiment at the LHC. From a data set corresponding to an integrated luminosity of 35.9 fb$^{-1}$, events containing one muon or electron and two or three jets are analysed. The cross section is measured as a function of the top quark transverse momentum ($p_\mathrm{T}$), rapidity, and polarisation angle, the charged lepton $p_\mathrm{T}$ and rapidity, and the $p_\mathrm{T}$ of the W boson from the top quark decay. In addition, the charge ratio is measured differentially as a function of the top quark, charged lepton, and W boson kinematic observables. The results are found to be in agreement with standard model predictions using various next-to-leading-order event generators and sets of parton distribution functions. Additionally, the spin asymmetry, sensitive to the top quark polarisation, is determined from the differential distribution of the polarisation angle at parton level to be 0.440 $\pm$ 0.070, in agreement with the standard model prediction.

An intriguing hyperelliptic Shimura curve quotient of genus 16

Publisher: name: arXiv

Subjects: subject: Number Theory (math.NT)
subject: FOS: Mathematics

description: Let $F$ be the maximal totally real subfield of $\mathbf{Q}(ζ_{32})$, the cyclotomic field of $32$nd roots of unity. Let $D$ be the quaternion algebra over $F$ ramified exactly at the unique prime above $2$ and 7 of the real places of $F$. Let $\mathcal{O}$ be a maximal order in $D$, and $X_0^D(1)$ the Shimura curve attached to $\mathcal{O}$. Let $C = X_0^D(1)/\langle w_D \rangle$, where $w_D$ is the unique Atkin-Lehner involution on $X_0^D(1)$. We show that the curve $C$ has several striking features. First, it is a hyperelliptic curve of genus $16$, whose hyperelliptic involution is exceptional. Second, there are $34$ Weierstrass points on $C$, and exactly half of these points are CM points; they are defined over the Hilbert class field of the unique CM extension $E/F$ of class number $17$ contained in $\mathbf{Q}(ζ_{64})$, the cyclotomic field of $64$th roots of unity. Third, the normal closure of the field of $2$-torsion of the Jacobian of $C$ is the Harbater field $N$, the unique Galois number field $N/\mathbf{Q}$ unramified outside $2$ and $\infty$, with Galois group $\mathrm{Gal}(N/\mathbf{Q})\simeq F_{17} = \mathbf{Z}/17\mathbf{Z} \rtimes (\mathbf{Z}/17\mathbf{Z})^\times$. In fact, the Jacobian $\mathrm{Jac}(X_0^D(1))$ has the remarkable property that each of its simple factors has a $2$-torsion field whose normal closure is the field $N$. Finally, and perhaps the most striking fact about $C$, is that it is also hyperelliptic over $\mathbf{Q}$.

description: 2D materials are emerging as promising nanomaterials for applications in energy storage and catalysis. In the wet chemical synthesis of MXenes, these 2D transition metal carbides and nitrides are terminated with a variety of functional groups, and cations such as Li+ are often used to intercalate into the structure to obtain exfoliated nanosheets. Given the various elements involved in their synthesis, it is crucial to determine the detailed chemical composition of the final product, in order to better assess and understand the relationships between composition and properties of these materials. To facilitate atom probe tomography analysis of these materials, a revised specimen preparation method is presented in this study. A colloidal Ti3C2Tz MXene solution was processed into an additive-free free-standing film and specimens were prepared using a dual beam scanning electron microscope / focused ion beam. To mechanically stabilize the fragile specimens, they were coated using an in situ sputtering technique. As various 2D material inks can be processed into such free-standing films, the presented approach is pivotal for enabling atom probe analysis of other 2D materials.

description: Tidal inlets are one of the most important elements of coastal areas. Many tidal inlets all around the world have been identified with a great variety of characteristics such as shape, size and sedimentary structure. In earlier studies, only the very large inlets, as well as those highly socio-economically valuable, were at the centre of interest for researchers at the request of managing authorities. At the present time, a great amount of resources is still being diverted to these larger inlets. In contrast, while smaller inlets are considered important to the daily lives and activities of local communities, for many of them, there is a challenging need to balance the maintenance costs with achievable benefits. Currumbin Creek is a small tidal inlet located in South-East Queensland, Australia. This creek has a long history of maintenance due to the partial closure of its entrance, as well as unsafe navigation through the entrance channel. Since 1981, when the two jetties at the entrance became operational, annual dredging has been required to keep the entrance open for all its different stakeholders. However, the current investment in dredging does not provide a desirable outcomes, and soon after each dredging campaign, the entrance exhibits shallowness and navigation difficulty. Hence, following some discrete and limited research, which was conducted during the last decade, this project has been introduced to investigate the issue of entrance viability by performing field measurements and a computer simulations. Data from various resources were collected and analysed, leading to a comprehensive project-specific field measurement campaign. The justification for this campaign was the need to collect as much concurrent data as possible, which could be used for the calibration and validation of the outputs of the computer modelling. Following that, a state-of-the-art process-based simulation method was chosen to conduct the necessary hindcasting and forecasting simulation.

Weisskopf-Wigner Decay Theory for the Energy-Driven Stochastic Schrödinger Equation
Creators: name: Adler, Stephen L.
Publisher: name: arXiv
Year: 2002
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We generalize the Weisskopf-Wigner theory for the line shape and transition rates of decaying states to the case of the energy-driven stochastic Schrödinger equation that has been used as a phenomenology for state vector reduction. Within the standard approximations used in the Weisskopf-Wigner analysis, and assuming that the perturbing potential inducing the decay has vanishing matrix elements within the degenerate manifold containing the decaying state, the stochastic Schrödinger equation linearizes. Solving the linearized equations, we find no change from the standard analysis in the line shape or the transition rate per unit time. The only effect of the stochastic terms is to alter the early time transient behavior of the decay, in a way that eliminates the quantum Zeno effect. We apply our results to estimate experimental bounds on the parameter governing the stochastic effects.

Η νομοθεσία αυτή αποτελεί ορόσημο για τον εκσυγχρονισμό και την ενίσχυση του νομικού πλαισίου που διέπει τις ΑΕ, οι οποίες διαδραματίζουν κομβικό ρόλο στην οικονομία της χώρας. Η παρούσα μελέτη εξετάζει σχολαστικά τις επιπτώσεις του Ν. 4548/2018 στις ελληνικές ΑΕ, προσφέροντας μια ολοκληρωμένη ανάλυση των βασικών διατάξεών του, των επιπτώσεών τους και της ευθυγράμμισής τους με τις διεθνείς πρακτικές. H μελέτη αξιολογεί τον βαθμό στον οποίο ο νόμος έχει ενισχύσει την προστασία των επενδυτών, έχει εξορθολογίσει τις διαδικασίες και έχει προσαρμοστεί στις τεχνολογικές εξελίξεις. Ορισμένες πτυχές που εξετάζονται συγκεκριμένα είναι: α) θέματα εταιρικής διακυβέρνησης, όπως η απλοποίηση των διαδικασιών, β) η χρήση της τεχνολογίας για τη διευκόλυνση της εταιρικής επικοινωνίας, γ) το ζήτημα του κρατικού ελέγχου στις Α.Ε. και δ) η ενδυνάμωση της μειοψηφίας με το νέο νομικό καθεστώς. Τελικά, η μελέτη υποστηρίζει ότι ο ελληνικός νόμος 4548/2018 ήταν ένα κομβικό βήμα προς τη σωστή κατεύθυνση, ενισχύοντας το επιχειρηματικό περιβάλλον, ενισχύοντας την εμπιστοσύνη των επενδυτών και τοποθετώντας τις ελληνικές Α.Ε. για ένα πιο ανταγωνιστικό και βιώσιμο μέλλον.

description: We propose a minimal extension of the standard model of particle physics to accommodate cosmic inflation, dark matter and light neutrino masses. While the inflationary phase is obtained from a modified chaotic inflation scenario, consistent with latest cosmology data, the dark matter particle is a fermion singlet which remains out of equilibrium in the early universe. The scalar field which revives the chaotic inflation scenario by suitable modification also assists in generating tiny couplings of dark matter with its mother particle, naturally realizing the non-thermal or freeze-in type dark matter scenario. Interestingly, the same assisting scalar field also helps in realizing tiny Yukawa couplings required to generate sub-eV Dirac neutrino mass from neutrino couplings to the standard model like Higgs field. The minimality as well as providing a unified solution to all three problems keep the model predictive at experiments spanning out to all frontiers.

description: Any deformation of a Weyl or Clifford algebra A can be realized through a `deforming map', i.e. a formal change of generators in A. This is true in particular if A is covariant under a Lie algebra g and its deformation is induced by some triangular deformation $U_h g$ of the Hopf algebra $Ug$. We propose a systematic method to construct all the corresponding deforming maps, together with the corresponding realizations of the action of $U_h g$. The method is then generalized and explicitly applied to the case that $U_h g$ is the quantum group $U_h sl(2)$. A preliminary study of the status of deforming maps at the representation level shows in particular that `deformed' Fock representations induced by a compact $U_h g$ can be interpreted as standard `undeformed' Fock representations describing particles with ordinary Bose or Fermi statistics.

description: Rahvastik vananeb ning seeläbi on meil tulevikus üha enam inimesi, kes elavad pikka aega mitmete krooniliste haigustega ning võtavad seetõttu igapäevaselt mitmeid ravimeid. Erinevate ravimite samaaegne võtmine võib aga suurendada kõrval- ja koostoimete tekke, kukkumise, kognitiivse võimekuse ja igapäevase toimetuleku vähenemise, hospitaliseerimise ja surma riski. Ravimite taandamine on oluline osa ravimite väljakirjutamisest. Tegemist on süstemaatilise protsessiga, mille eesmärk on patsiendi raviskeemist leida üles ravimid, mis toovad rohkem kahju kui kasu, ning vähendada nende ravimite annust või lõpetada nendega ravi. Ravimite taandamise abil soovitakse vähendada võimalikke kõrval- ja koostoimeid ning ennetada nendest tulenevaid probleeme ning seeläbi parandada patsiendi elukvaliteeti. Peamine sihtrühm on vanemaealised mitmete krooniliste haigustega ning viit või enamat ravimit tarvitavad patsiendid. Artikli eesmärk on anda ülevaade ravimite taandamise eesmärkidest, sihtrühmast, protsessist ning võimalikest takistustest.

C-hepatiidi ja rinnavähi sõeluuring naistel vanuses 50–69 aastat

description: Taust. Maailma Terviseorganisatsioon püstitas 2016. aastal eesmärgi likvideerida C-hepatiit maailmas 2030. aastaks. Eestis C-hepatiidi viiruse (HCV) riiklikku sõeluuringut ei rakendata. Haiguse varajane avastamine ja ravi piirab haiguse levikut ning võimaldab ennetada tõsiste hilistüsistuste teket.
Eesmärgid. Uuringu eesmärk oli saada ülevaade C-hepatiidi viiruse levimusest 50–69aastaste naiste hulgas, hinnata HCV-vastaste antikehade võimalikku seost mammograafialeidudega ja kirjeldada HCVga nakatumise peamisi teid selles vanuserühmas.
Metoodika. Uuringus osalemise võimalust pakuti rinnavähi sõeluuringule pöördunud 50–69aastastele naistele. Uuritav täitis riskiküsimustiku ja talle tehti HCV-vastaste antikehade kiirtest näpuotsaverest. Positiivse tulemuse korral tehti uuritavale kvalitatiivne HCV RNA uuring. Patsientidele, kes said positiivse HCV RNA proovi vastuse, anti vastutava uurija telefoninumber, kes andis edasised tegevusjuhised.
Tulemused. Uuringus osalenud 4495 naisest said HCV-vastaste antikehade testil positiivse tulemuse 0,4% (n = 18) ja HCV RNA testil 0,07% (n = 3). HCV-vastaste antikehade olemasolu suhteline risk oli kõrgem uuritavatel, kes olid saanud hemodialüüsi, kellele oli tehtud vereülekanne enne 1994. aastat ning kelle maksafunktsiooni näitajad olid suurenenud. Mammograafialeide, mis vajasid edasisi täpsustavaid uuringuid, oli 115, neist HCV-vastaste antikehade suhtes positiivseid uuritavaid 0.
Järeldused. Mammograafiakabinetti rinnavähi sõeluuringule pöördunud 50–69aastaste naiste hulgas oli HCV-vastaste antikehade levimus madalam tavarahvastikust. HCV-vastaste antikehade esinemise seost positiivsete mammograafialeidudega ei tuvastatud. Võimalikuks peamiseks HCVga nakatumise teeks 50–69aastaste naiste hulgas oli vereülekanne enne 1994. aastat. Sõeluuringuprogrammide integreerimine mobiilse tervishoiuteenusega võimaldab saavutada sihtrühma väga hea osaluse.

description: Several no-go theorems showed the incompatibility between the locality assumption and quantum correlations obtained from maximally entangled spin states. We analyze these no-go theorems in the framework of Bohm's interpretation. The mechanism by which non-local correlations appear during the results of measurements performed on distant parts of entangled systems is explicitly put into evidence in terms of Bohmian trajectories. It is shown that a GHZ like contradiction of the type+1=-1 occurs for well-chosen initial positions of the Bohmian trajectories and that it is this essential non-classical feature that makes it possible to violate the locality condition.

description: We prove a microlocal lower bound on the mass of high energy eigenfunctions of the Laplacian on compact surfaces of negative curvature, and more generally on surfaces with Anosov geodesic flows. This implies controllability for the Schrödinger equation by any nonempty open set, and shows that every semiclassical measure has full support. We also prove exponential energy decay for solutions to the damped wave equation on such surfaces, for any nontrivial damping coefficient. These results extend previous works [arXiv:1705.05019], [arXiv:1712.02692], which considered the setting of surfaces of constant negative curvature. The proofs use the strategy of [arXiv:1705.05019], [arXiv:1712.02692] and rely on the fractal uncertainty principle of [arXiv:1612.09040]. However, in the variable curvature case the stable/unstable foliations are not smooth, so we can no longer associate to these foliations a pseudodifferential calculus of the type used in [arXiv:1504.06589]. Instead, our argument uses Egorov's Theorem up to local Ehrenfest time and the hyperbolic parametrix of [arXiv:0706.3242], together with the $C^{1+}$ regularity of the stable/unstable foliations.

description: Fulton asked how many solutions to a problem of enumerative geometry can be real, when that problem is one of counting geometric figures of some kind having specified position with respect to some general fixed figures. For the problem of plane conics tangent to five general conics, the (surprising) answer is that all 3264 may be real. Similarly, given any problem of enumerating p-planes incident on some general fixed subspaces, there are real fixed subspaces such that each of the (finitely many) incident p-planes are real. We show that the problem of enumerating parameterized rational curves in a Grassmannian satisfying simple (codimension 1) conditions may have all of its solutions be real.

description: Testing scenario library generation (TSLG) is a critical step for the development and deployment of connected and automated vehicles (CAVs). In Part I of this study, a general methodology for TSLG is proposed, and theoretical properties are investigated regarding the accuracy and efficiency of CAV evaluation. This paper aims to provide implementation examples and guidelines, and to enhance the proposed methodology under high-dimensional scenarios. Three typical cases, including cut-in, highway-exit, and car-following, are designed and studied in this paper. For each case, the process of library generation and CAV evaluation is elaborated. To address the challenges brought by high dimensions, the proposed methodology is further enhanced by reinforcement learning technique. For all three cases, results show that the proposed methods can accelerate the CAV evaluation process by multiple magnitudes with same evaluation accuracy, if compared with the on-road test method.

description: Fractional Brownian motion is a Gaussian stochastic process with stationary, long-time correlated increments and is frequently used to model anomalous diffusion processes. We study numerically fractional Brownian motion confined to a finite interval with reflecting boundary conditions. The probability density function of this reflected fractional Brownian motion at long times converges to a stationary distribution showing distinct deviations from the fully flat distribution of amplitude $1/L$ in an interval of length $L$ found for reflected normal Brownian motion. While for superdiffusion, corresponding to a mean squared displacement $\langle X^2(t)\rangle\simeq t^α$ with $1

Nonlinear structure formation in Bound Dark Energy

description: We study nonlinear structure formation in the Bound Dark Energy model (BDE), where dark energy (DE) corresponds to a light scalar meson particle $ϕ$ dynamically formed at a condensation energy scale $Λ_c$. The evolution of this dark-energy meson is determined by the potential $V(ϕ)=Λ_c^{4+2/3}ϕ^{-2/3}$, with a distinguishing phenomenology from other quintessence scenarios. Particularly, the expansion rate of the universe is affected not only at late times, but also when the condensation of $ϕ$ occurs, which in linear theory leads to an enhancement (with respect to standard $Λ$CDM) of matter perturbations on small scales. We study how much of this signature is still present at late times as well as the properties of dark matter halos in the nonlinear regime through N-body simulations. Our results show that nonlinear corrections wash out this feature from the matter power spectrum even before DE becomes dominant. There is, however, a small but clear suppression of the BDE spectrum of $2\%$ today on the largest scales due to the distinct late-time dynamics of DE. The differences on the clustering power between BDE and $Λ$CDM are reflected in the halo mass function, where small halos are more abundant in BDE as opposed to large heavy structures, whose formation is delayed because of the expansion history of the universe. This result is well captured by the semi-analytical Sheth-Tormen formula. However, despite these differences, the halo concentration parameter is essentially the same in both models, which suggest that clustering inside the halos decouple from the general expansion once the halos form.

Deconstructing G Protein-Coupled Receptor Dimer Pharmacology: Case Studies in Dopamine D1 and D2 Receptors

description: Dopamine receptors mediate various important neurophysiological functions. At a molecular level, G protein coupling is considered the main activation mechanism for most of the receptor-mediated cellular processes. A number of studies using native tissue have supported the idea that receptors can interact to form dimers or higher order oligomers. Particularly in medium spiny neurons of the striatum, dopamine receptor subtypes are reported to form dimers with themselves or other receptors (e.g. adenosine receptor A2A). Although a functional relevance for these dimers has been proposed, current assay systems are not capable of teasing out dimer-specific signaling events from those from other receptor populations. We have developed an assay that allows investigation of receptor-effector coupling specifically with defined dimer pairs. Using this assay, we investigated putative dopamine D1-D2 and A2A-D2 receptor dimer functions and studied the issue of a purported G protein coupling switch in the D1-D2 receptor dimer in which the heteromer was proposed to activate Gq, unlike D1 or D2 receptor when expressed alone. We were unable, however, to find evidence for Gq activation by the D1-D2 heteromer, as the protomers in the heteromer maintained fidelity of signaling to their cognate G proteins. We also developed and optimized a series of novel Gs biosensors to elucidate differences in heterotrimeric G protein conformational changes triggered by dopamine D1 and A2A receptors, two of the prominent pharmacological targets in the striatum. In addition to G protein signaling, intracellular calcium is also involved in many important cellular functions in all cell types. In neurons, intracellular calcium is implicated in learning and memory (synaptic plasticity) as well as neurodegeneration (apoptosis). In medium spiny neurons, dopamine-mediated calcium release from internal stores has been reported to result from activation of phospholipase C (PLC). However, different subtypes of dopamine receptors and intermediary proteins have been proposed to play a role in this dopamine-mediated PLC activation, and the underlying mechanisms are unclear. We found that activation of D1 and D2 receptors expressed individually can mobilize calcium in a PLC-dependent manner. In parallel, we also examined D1 and D2 receptor colocalization in striatal brain slices as well as in cultured medium spiny neurons. Although we found evidence using bacterial artificial chromosome-D1 and D2 reporter mice that D1 and D2 receptors are co-expressed in a small number of brain regions, we failed to observe D1-D2 receptor colocalization, suggesting the possibility that in neurons the receptors are somehow segregated.

description: This paper problematises the question of how policy-relevant knowledge is produced, how it can include concerns of all stakeholders, and how it informs political processes, by focussing on a specific case. To do so, it surveys literature on impacts of resource expropriation and processes of exclusion on indigenes in central eastern India. It examines how a shift to local democracy in recent decades can potentially facilitate inclusion of concerns of indigenes and the environment in natural resource governance within this resource-rich but poverty-stricken conflict zone. It argues that, in order to enable democratic resource governance, evidence-based knowledge must inform changes in institutional processes. It makes the case for a doctoral project being undertaken during 2012-15 that seeks to generate such knowledge. The project emphasizes the importance of understanding the relationship between decentralisation reforms and indigenous communities’ rights and participation in natural resource governance, in order to enable inclusive governance in a conflict zone of economic, political, ethnic and ecological interests. This paper justifies why this knowledge is required and describes the methodological approach adopted to generate it. It also preliminarily identifies gaps in the political process, explaining why it is challenging for such research to facilitate better implementation even if it does feed back into more evidence-based policy.

description: Graphene is an innovative nanomaterial, made of two-dimensional honeycomb-like carbon lattice, with potential in many different applications. Studying the behaviour of graphene-related materials (GRMs) in biological systems is, therefore, crucial to assess possible side effects. In this work is studied the biotransformation and biological impact of few-layer pristine graphene (FLG) and graphene oxide (GOX), following ingestion as exposure route. To mimic FLG and GOX ingestion, an in vitro digestion assay based on a standardized operating procedure (SOP) is applied. The assay simulates the human ingestion of GRMs during their dynamic passage through the different environments of gastrointestinal (GI) tract (salivary, gastric, intestinal). Physical-chemical changes of GRMs during the digestion process are assessed through a detailed Raman spectroscopy characterization. Moreover, the effect of chronic exposure to digested GRMs on integrity and functionality of an in vitro model of intestinal barrier is also determined according to a second SOP. Our results showed that the FLG and GOX nanoflakes aggregates after experiencing the passage through the different environments of GI tract, with evident doping effects, due to the interaction of GRMs with digestive juice components and the strong pH variations. Interestingly, neither structural changes nor degradation of the nanomaterials is observed, suggesting that GRMs are bio-persistent nanomaterials when administered by oral route. Chronic exposure to digested GRMs does not affect intestinal barrier integrity and is not associated to inflammation and cytotoxicity, though possible long-term adverse effects cannot be ruled out, due to the observed bio-durability of the materials.
