description: We present the results of a Suzaku study of the Arches cluster. A high S/N spectrum in the 3-12 keV band was obtained with the XIS. We found that the spectrum consists of a thermal plasma, a hard power-law tail, and two Gaussian lines. The plasma component (kT~2.2 keV) is established from the presence of CaXIX and FeXXV K alpha lines as well as the absence of FeXXVI K alpha line. The two Gaussian lines represent the K alpha and beta lines from iron at lower ionization stages. Both the line centers and the intensity ratio of these two lines are consistent with the neutral iron. The hard power-law tail (index~0.7) was found to have no pronounced iron K edge feature. In comparison with the published Chandra spectra, we conclude that the thermal component is from the ensemble of point-like sources plus thermal diffuse emission concentrated at the cluster center, while the Gaussian and the hard tail components are from the non-thermal diffuse emission extended in a larger scale. In the band-limited XIS images, the distribution of the 7.5-10.0 keV emission resembles that of the 6.4 keV emission. This strongly suggests that the power-law emission is related to the 6.4 and 7.1 keV lines in the underlying physics. We discuss two ideas to explain both the hard continuum and the lines: (1) X-ray photoionization that produces fluorescence lines and the Thomson scattering continuum and (2) non-thermal electron impact ionization of iron atoms and bremsstrahlung continuum. But whichever scenario is adopted, the photon or particle flux from the Arches cluster is too low to account for the observed line and continuum intensity.

title: Inherent pedagogies : critical approaches to exhibition making in the 2000s
Creators: name: González Rueda, Ana Sol
Publisher: name: University of St Andrews
Year: 2019

description: Since 2010, the discussion about the relation between curating and education has revolved around Paul O’Neill and Mick Wilson’s proposition of the ‘educational turn’. This term mainly refers to the shift from the peripheral, supportive part of educational activities in relation to exhibitions, to their increased centrality within contemporary curatorial practice. While expressly educational initiatives have received plenty of attention, this thesis concentrates on the inherent pedagogies of the contemporary art exhibition space. The research draws attention to this aspect, particularly regarding critical curatorial approaches that seek to contest prevailing neoliberal educational and cultural policy across Europe. The thesis contributes to exhibition histories in its examination of four chapter-long case studies that were selected on the basis that they propose other modes of spectatorship to the prevalent model of entertained consumption. It also makes a contribution to curatorial studies by delving into distinct critical approaches and integrating interviews conducted with the curators in each case. Most importantly, this study presents the potential of educational theory to both examine and rethink the positions and relations exhibitions organise between institutions, curators, artworks, and the public. Specifically, I put forward the potential contribution of posthumanist, feminist materialist, and decolonial pedagogies to current curatorial practice. These particular methods are supportive of the challenge to Western, modern epistemology set out across the chapters through boundary crossings such as aesthetic experience/discourse, mind/ body, artwork/viewer, the self/the other. I argue that, as curators, we need to unlearn the established —but largely unacknowledged— educational conventions of the field, explore other ways of learning, and set about unschooling contemporary art exhibitions.
Long-range SL(2) Baxter equation in N=4 super-Yang-Mills theory

description: Relying on a few lowest order perturbative calculations of anomalous dimensions of gauge invariant operators built from holomorphic scalar fields and an arbitrary number of covariant derivatives in maximally supersymmetric gauge theory, we propose an all-loop generalization of the Baxter equation which determines their spectrum. The equation does not take into account wrapping effects and is thus asymptotic in character. We develop an asymptotic expansion of the deformed Baxter equation for large values of the conformal spin and derive an integral equation for the cusp anomalous dimension.

description: We propose a general self-supervised learning approach for spatial perception tasks, such as estimating the pose of an object relative to the robot, from onboard sensor readings. The model is learned from training episodes, by relying on: a continuous state estimate, possibly inaccurate and affected by odometry drift; and a detector, that sporadically provides supervision about the target pose. We demonstrate the general approach in three different concrete scenarios: a simulated robot arm that visually estimates the pose of an object of interest; a small differential drive robot using 7 infrared sensors to localize a nearby wall; an omnidirectional mobile robot that localizes itself in an environment from camera images. Quantitative results show that the approach works well in all three scenarios, and that explicitly accounting for uncertainty yields statistically significant performance improvements.

description: Σκοπός της παρούσας διατριβής είναι να εξεταστούν δυο απόβλητα βιομηχανιών τροφίμων, οι φλοιοί ροδιού και τα απόβλητα χυμοποίησης πορτοκαλιού, ως προσροφητικά υλικά για την απομάκρυνση των φαινολικών ενώσεων από τα απόβλητα ελαιουργείου. Τα υλικά αυτά μελετούνται αφού πρώτα απομακρύνεται το φαινολικό τους περιεχόμενο. Έτσι, η προσρόφηση αποτελεί το δεύτερο βήμα για μια ολοκληρωμένη προσέγγιση της πλήρους αξιοποίησης των δύο αυτών αποβλήτων, αλλά κυρίως και των υγρών αποβλήτων ελαιουργείων, επιτυγχάνοντας την αποτοξικοποίησή τους με την παραλαβή βιοδραστικών ουσιών, που μπορούν να χρησιμοποιηθούν ως αντιοξειδωτικά πρόσθετα σε διάφορα σκευάσματα. Αρχικά, μελετούνται οι επιδράσεις διαφόρων παραγόντων στην απόδοση της προσρόφησης, όπως η συγκέντρωση του προσροφητικού υλικού, η θερμοκρασία, το pH του διαλύματος, η αρχική συγκέντρωση φαινολικών ενώσεων και το μέγεθος σωματιδίων του προσροφητικού υλικού. Για την κατανόηση του μηχανισμού της προσρόφησης, πραγματοποιήθηκαν πειράματα εκρόφησης. Μελετήθηκαν επίσης κινητικά μοντέλα διάχυσης και οι ισόθερμες ρόφησης. Μελετήθηκε η αλλαγή της προσροφητικής ικανότητας του υλικού με τη θερμική και χημική αναγέννηση, καθώς και η ανάκτηση των προσροφημένων φαινολικών ενώσεων με τη μέθοδο της ξήρανσης ψεκασμού
description: The purpose of this work is to consider the potential of two food wastes derived from agricultural activities, the non-modified pomegranate peel and orange juice by-product, after the removal of their own phenolic content, for phenolics sorption from olive mill wastewater. This procedure is the second step of an integrated approach for complete utilization of these wastes in recovering valuable ingredients, while succeeding total depollution using them as additives in various products. Initially, the equilibrium time was investigated and afterwards, the effects of sorbent mass concentration, temperature, solution’s pH, initial sorbate concentration, and sorbent particle size on total phenols uptake were studied in batch experiments. Desorption experiments were studied to determine the adsorption mechanism. Diffusion models and sorption isotherms were studied. Thermal and chemical regeneration was studied, while the recovery of the adsorbed phenolic compounds was studied by the spray-drying method

This is achieved by incorporating two different modules: a Computational Auditory Scene Analysis CASA based pre-processing module for noise reduction and cascaded Gaussian Mixture Model Convolutional Neural Network GMM-CNN classifier for speaker identification followed by emotion recognition. This research proposes and evaluates a novel algorithm to improve the accuracy of speaker identification in emotional and highly-noise susceptible conditions. Experiments demonstrate that the proposed model yields promising results in comparison with other classifiers when Speech Under Simulated and Actual Stress SUSAS database, Emirati Speech Database ESD, the Ryerson Audio-Visual Database of Emotional Speech and Song RAVDESS database and the Fluent Speech Commands database are used in a noisy environment.

description: We analyze the electromagnetic field near a plane interface between a conductive and a dielectric media, under conditions supporting surface plasmon-polariton (SPP) propagation. The conductive medium is described by the hydrodynamic electron-gas model that enables a consistent analysis of the field-induced variations of the electron density and velocity at the interface and its nearest vicinity. The distributions of electromagnetic dynamical characteristics: energy, energy flow, spin and momentum are calculated analytically and illustrated numerically, employing silver-vacuum interface as an example. A set of the "field" and material contributions to the energy, spin and momentum are explicitly identified and classified with respect to their physical origins and properties, and the orbital (canonical) and spin (Belinfante) momentum constituents are separately examined. In this context, a procedure for the spin-orbital momentum decomposition in the presence of free charges is proposed and substantiated. The microscopic results agree with the known phenomenological data but additionally show specific nanoscale structures in the near-interface behavior of the SPP energy and momentum, which can be deliberately created, controlled and used in nanotechnology applications.

Conformal Bootstrap near the edge

Year: 2021
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We propose a bootstrap program for CFTs near intersecting boundaries which form a co-dimension 2 edge. We describe the kinematical setup and show that bulk 1-pt functions and bulk-edge 2-pt functions depend on a non-trivial cross-ratio and on the angle between the boundaries. Using the boundary OPE (BOE) with respect to each boundary, we derive two independent conformal block expansions for these correlators. The matching of the two BOE expansions leads to a crossing equation. We analytically solve this equation in several simple cases, notably for a free bulk field, where we recover Feynman-diagrammatic results by Cardy.

description: The results of 27 hours of time series photometry of SDSS 121209.31+013627.7 are presented. The binary period established from spectroscopy is confirmed and refined to 0.061412 d (88.43 minutes). The photometric variations are dominated by a brightening of about 16 mmag, lasting a little less than half a binary cycle. The amplitude is approximately the same in V, R and white light. A secondary small brightness increase during each cycle may also be present. We speculate that SDSS 121209.31+013627.7 may be a polar in a low state.

description: We present a theoretical treatment of Bragg scattering of a degenerate Fermi gas in the weakly interacting BCS regime. Our numerical calculations predict correlated scattering of Cooper pairs into a spherical shell in momentum space. The scattered shell of correlated atoms is centered at half the usual Bragg momentum transfer, and can be clearly distinguished from atoms scattered by the usual single-particle Bragg mechanism. We develop an analytic model that explains key features of the correlated-pair Bragg scattering, and determine the dependence of this scattering on the initial pair correlations in the gas.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We study the behavior of Rényi entropies for pure states from standard assumptions about chaos in the high-energy spectrum of the Hamiltonian of a many-body quantum system. We compute the exact long-time averages of Rényi entropies and show that the quantum noise around these values is exponentially suppressed in the microcanonical entropy. For delocalized states over the microcanonical band, the long-time average approximately reproduces the equilibration proposal of H. Liu and S. Vardhan, with extra structure arising at the order of non-planar permutations. We analyze the equilibrium approximation for AdS/CFT systems describing black holes in equilibrium in a box. We extend our analysis to the situation of an evaporating black hole, and comment on the possible gravitational description of the new terms in our approximation.

description: Exact parsing with finite state automata is deemed inappropriate because of the unbounded non-locality languages overwhelmingly exhibit. We propose a way to structure the parsing task in order to make it amenable to local classification methods. This allows us to build a Dynamic Bayesian Network which uncovers the syntactic dependency structure of English sentences. Experiments with the Wall Street Journal demonstrate that the model successfully learns from labeled data.

description: We derive the Boltzmann equation and the collision kernel for massive spin-1/2 particles, using the Wigner-function formalism and employing an expansion in powers of $\hbar$. The phase space is enlarged to include a variable related to the spin degrees of freedom. This allows to reduce the transport equations of the independent components of the Wigner function to one scalar equation. To next-to-leading order in $\hbar$, we find that the collision kernel contains both local and nonlocal terms. We show that off-shell contributions cancel in the Boltzmann equation. Our framework can be used to study spin-polarization phenomena induced by vorticity as recently observed in heavy-ion collisions and in condensed-matter systems.

description: High energy resolution C 1$s$ photoelectron spectra of graphite were measured at the excitation energy of 340, 870, 5950 and 7940eV using synchrotron radiation. On increasing the excitation energy, i.e., increasing kinetic energy of the photoelectron, the bulk origin C 1$s$ peak position shifts to higher binding energies. This systematic shift is due to the kinetic energy loss of the high-energy photoelectron by kicking the atom, and is clear evidence of the recoil effect in photoelectron emission. It is also observed that the asymmetric broadening increases for the higher energy photoelectrons. All these recoil effects can be quantified in the same manner as the Mössbauer effect for $γ$-ray emission from nuclei embedded in crystals.

description: We show that it is possible to realize a cosmological bouncing solution in an anisotropic but homogeneous Bianchi-I background in a class of non-local, infinite derivative theories of gravity. We show that the anisotropic shear grows slower than in general relativity during the contraction phase, peaks to a finite value at the bounce point, and then decreases as the universe asymptotes towards isotropy and homogeneity, and ultimately to de Sitter. Along with a cosmological constant, the matter sector required to drive such a bounce is found to consist of three components - radiation, stiff matter and $k$-matter (whose energy density decays like the inverse square of the average scale factor). Generically, $k$-matter exerts anisotropic pressures. We will test the bouncing solution in local and non-local gravity and show that in the latter case it is possible to simultaneously satisfy positivity of energy density and, at least in the late time de Sitter phase, avoid the introduction of propagating ghost/tachyonic modes.

description: An exact description of integrable spin chains at finite temperature is provided using an elementary algebraic approach in the complete Hilbert space of the system. We focus on spin chain models that admit a description in terms of free fermions, including paradigmatic examples such as the one-dimensional transverse-field quantum Ising and XY models. The exact partition function is derived and compared with the ubiquitous approximation in which only the positive parity sector of the energy spectrum is considered. Errors stemming from this approximation are identified in the neighborhood of the critical point at low temperatures. We further provide the full counting statistics of a wide class of observables at thermal equilibrium and characterize in detail the thermal distribution of the kink number and transverse magnetization in the transverse-field quantum Ising chain.

description: Chalcogenide phase-change materials (PCMs) are regarded as the leading candidate for storage-class non-volatile memory and neuro-inspired computing. Recently, using the $TiTe_2$/$Sb_2Te_3$ material combination, a new framework - phase-change heterostructure (PCH), has been developed and proved to effectively suppress the noise and drift in electrical resistance upon memory programming, largely reducing the inter-device variability. However, the atomic-scale structural and chemical nature of PCH remains to be fully understood. In this work, we carry out thorough ab initio simulations to assess the bonding characteristics of the PCH. We show that the $TiTe_2$ crystalline nanolayers do not chemically interact with the surrounding $Sb_2Te_3$, and are stabilized by strong covalent and electrostatic Ti-Te interactions, which create a prohibitively high barrier for atomic migrations along the pulsing direction. We also find significant contrast in computed dielectric functions in the PCH, suggesting possible optical applications of this class of devices. With the more confined space and therefore constrained phase transition compared to traditional PCM devices, the recently introduced class of PCH-based devices may lead to improvements in phase-change photonic and optoelectronic applications with much lower stochasticity during programming.

description: Objective: Diarrhea-predominant irritable bowel syndrome (IBS-D) is the main subtype of IBS, a chronic functional gastrointestinal disorder. Small intestinal bacterial overgrowth (SIBO), which is characterized by dysbiosis of the bowel, causes gastrointestinal symptoms quite similar to IBS-D. However, whether SIBO correlates with IBS-D and its further mechanism remain unknown. Materials and Methods: The study included 60 IBS-D patients that fulfilled Rome IV criteria and 60 healthy controls. All subjects were undergoing a lactose breath test (LBT) to diagnose SIBO. IBS-D patients were further assigned to negative SIBO (SIBO-) subgroup and positive SIBO (SIBO+) subgroup to analyze the scores of symptoms and differences in the fecal microbiota. Results: The prevalence of SIBO in IBS-D patients was higher than that in healthy controls (51.7% vs. 16.7%, p ≤ .001). In addition, IBS-SSS in SIBO+ subgroup was significantly higher than SIBO- subgroup (p = .015). The 16S rRNA analyses showed that composition and abundance of fecal microbiota were obviously different between the two subgroups. There was a remarkable increase in Prevotella in IBS-D patients, especially in IBS-D SIBO+ sufferers. Meanwhile, there were a moderately positive correlation of the abundance of Prevotella (rho = 0.458, p ≤ .001) with IBS-SSS. Conclusion: SIBO is associated with IBS-D, which may be related to alteration in the intestinal microbiota. These findings suggest the potent role of Prevotella in gastrointestinal symptoms between SIBO and IBS-D, thus provide a novel insight into the connection between SIBO and IBS-D.

Holographic Renormalization of Gravity in Little String Theory Duals

description: We perform a holographic renormalization of gravity duals to little string theories. In particular, we construct counterterms which yield a well-defined type II action for NS-sector linear dilaton backgrounds. Our methods are based on a similar recent construction in asymptotically flat spacetimes, and our work demonstrates in detail the parallels between asymptotically flat and linear dilaton boundary conditions. The counterterms guarantee that (i) the on-shell action is finite and (ii) asymptotically linear dilaton solutions are stationary points of the action under all boundary condition preserving variations. We use the resulting action to compute a boundary stress tensor and the associated conserved charges.

description: Ultra-short pulses propagating in nonlinear nanophotonic waveguides can simultaneously leverage both temporal and spatial field confinement, promising a route towards single-photon nonlinearities in an all-photonic platform. In this multimode quantum regime, however, faithful numerical simulations of pulse dynamics naïvely require a representation of the state in an exponentially large Hilbert space. Here, we employ a time-domain, matrix product state (MPS) representation to enable efficient simulations by exploiting the entanglement structure of the system. In order to extract physical insight from these simulations, we develop an algorithm to unravel the MPS quantum state into constituent temporal supermodes, enabling, e.g., access to the phase-space portraits of arbitrary pulse waveforms. As a demonstration, we perform exact numerical simulations of a Kerr soliton in the quantum regime. We observe the development of non-classical Wigner-function negativity in the solitonic mode as well as quantum corrections to the semiclassical dynamics of the pulse. A similar analysis of $χ^{(2)}$ simultons reveals a unique entanglement structure between the fundamental and second harmonic. Our approach is also readily compatible with quantum trajectory theory, allowing full quantum treatment of propagation loss and decoherence. We expect this work to establish the MPS technique as part of a unified engineering framework for the emerging field of broadband quantum photonics.

description: Converse effect of spin photocurrent and current induced spin polarization are experimentally demonstrated in the same two-dimensional electron gas system with Rashba spin splitting. Their consistency with the strength of the Rashba coupling as measured from beating of the Shubnikov-de Haas oscillations reveals a unified picture for the spin photocurrent, current-induced spin polarization and spin orbit coupling. In addition, the observed spectral inversion of the spin photocurrent indicates the system with dominating structure inversion asymmetry.

On the hard $γ$-ray spectrum of the potential PeVatron supernova remnant G106.3+2.7

description: The Tibet AS$γ$ experiment has measured $γ$-ray flux of supernova remnant G106.3+2.7 up to 100 TeV, suggesting it {being} potentially a "PeVatron". Challenge arises when the hadronic scenario requires a hard proton spectrum (with spectral index $\approx 1.8$), while {usual observations and numerical simulations prefer} a soft proton spectrum {(with spectral index $\geq 2$)}. In this paper, we explore an alternative scenario to explain the $γ$-ray spectrum of G106.3+2.7 within the current understanding of acceleration and escape processes. We consider that the cosmic ray {particles} are scattered by the turbulence driven via Bell instability. The resulting hadronic $γ$-ray spectrum is novel, dominating the contribution to the emission above 10\,TeV, and can explain the bizarre broadband spectrum of G106.3+2.7 in combination with leptonic emission from the remnant.

description: In this paper we derive an analytic approximation to the density of states for atoms in a combined optical lattice and harmonic trap potential as used in current experiments with quantum degenerate gases. We compare this analytic density of states to numerical solutions and demonstrate its validity regime. Our work explicitly considers the role of higher bands and when they are important in quantitative analysis of this system. Applying our density of states to a degenerate Fermi gas we consider how adiabatic loading from a harmonic trap into the combined harmonic-lattice potential affects the degeneracy temperature. Our results suggest that occupation of excited bands during loading should lead to more favourable conditions for realizing degenerate Fermi gases in optical lattices.

description: GW170817 has provided valuable constraints on the equations of state of merging binary neutron stars, which can be considered as the most probable candidate for the source of gravitational waves. On the other hand, these natural laboratories of extreme temperature and density may lead to the estimation of some exotic matter like {deconfined quark matter in their cores}. In this paper, we investigate the neutron star matter equation of state (EoS) with the lowest order constrained variational (LOCV) method considering the excluded volume effect (VLOCV) for nucleons {to} compute the tidal deformability of binary neutron star mergers (BNSMs). Within this approach, the size of nucleons makes the EoS {so} stiff that requires a phase transition in order to avoid causality violation. Therefore, this phase transition {may lead} to the appearance of the third family of compact stars {including} ``twin star'' configurations. {Our EoS models are confronted with observations from GW170817, GW190814, GW190425, and also NICER. We find out that regarding all these constraints, the EoS models having the {transition} pressure$\approx$30-100 MeV/fm$^{3}$ and the energy density discontinuity $Δ\varepsilon$$\lesssim$300 MeV/fm$^{3}$ are preferable.

THE STATUTE ON HOMOLOGEIN IN HYPERIDES’ SPEECH AGAINST ATHENOGENES
Creators: name: Thür, Gerhard
Publisher: name: Dike
Year: 2014

description: The paper focuses on the structure of contract in Athenian law and the liability to comply with. After a short outline of the meaning and the practical relevance of ‘consensual contracts’ in classical Roman law and their further development in late Antiquity up to modern times the one-century-old controversy about contract in ancient Greek law is resumed: on the one hand the ‘consensualists’ hold that the verb homologein (literally “speak the same”) means “promise to comply with debts.” On the other hand the ‘realists’ argue that the binding force of a contract was not created by a simple promise, but rather through a real basis. The debtor was only liable when he had accepted some goods or assets from the creditor and was frustrating the purpose, for which the creditor had rendered them to him, the so-called ‘Zweckverfügung’ (disposition for a certain purpose, Hans Julius Wolff). One of the crucial sources is the nomos on homologein quoted in Hyperides’ speech Against Athenogenes (§ 13). Compared with quotations of similar statutes (Dem. 42.12, 56.2) it will turn out that in technical sense homologein was only related to court procedure: “in whatever regard someone says the same as another, this is definitive (in the law court)” and did not create obligations.

Barriers & Enablers of Intercropping and Enhanced Crop Diversification in the UK

Subjects: Crop Diversification

description: Increasingly volatile weather conditions and extreme weather events have increased challenges in pest management in single variety cropping. A need to enhance Integrated Pest Management (IPM) has led to the use of plant species mixtures or ‘plant teams’ to optimise performance, improve yield stability, reduce pest and disease damage and enhance stress resilience in agricultural systems. Combined with supporting Integrated Farm Management (IFM) practices, intercropping, in field crop mixtures and other examples of enhanced crop diversification have gained attention in recent years due to the beneficial effects of soil fertility, nutrient recycling and pest, weed and disease management. However, uptake remains limited in the UK. Barriers to and opportunities presented by enhanced crop diversification are illustrated through a series of case studies from across three projects LEAF collaborated on between 2017 and 2020. Enablers and barriers to adoption of enhanced crop diversification are illustrated, concluding that a range of approaches will be necessary to support upscaling of these practices in the UK.

ATHENIAN IMPIETY TRIALS: A REAPPRAISAL
Creators: name: Filonik, Jakub
Publisher: name: Dike
Year: 2014

description: This paper aims to critically analyse the testimonies concerning Athenian impiety trials of the classical period. First, it reaffirms the arguments that some of them must have been an invention of Hellenistic and later authors. Second, it presents a likely political background behind the historical cases. Third, it discusses a number of legal issues, along with new arguments concerning the procedures employed. Finally, it examines some less well-known material from the fourth century BCE. Overall, it seeks to provide a possibly coherent and comprehensive framework of Athenian impiety trials based on their shared characteristics.

description: The anisotropy of magnetophydrodynamic turbulence is investigated by using solar wind data from the Helios 2 spacecraft. We investigate the behaviour of the complete high-order moment tensors of magnetic field increments and we compare the usual longitudinal structure functions which have both isotropic and anisotropic contributions, to the fully anisotropic contribution. Scaling exponents have been extracted by an interpolation scaling function. Unlike the usual turbulence in fluid flows, small-scale magnetic fluctuations remain anisotropic. We discuss the radial dependence of both anisotropy and intermittency and their relationship.

description: There are still several unanswered fundamental questions concerning our planet and in particular, about the deep Earth, from where we lack direct samples. Today, due to the progress in neutrino-detection techniques, a new and unique tool to study our planet exists: geoneutrinos, antineutrinos from the decays of long-lived radioactive elements inside the Earth. In 2020, the Borexino experiment published its updated geoneutrino measurement. Thanks to the increase in acquired data and the improved analysis techniques in an enlarged fiducial volume, the final precision has significantly improved, corresponding to a total geoneutrino signal of 47.0$^{+8.4}_{-7.7}\,({\rm stat)}^{+2.4}_{-1.9}\,({\rm sys})$ TNU. The null-hypothesis of the geoneutrino signal from the Earth's mantle was excluded at a 99% C.L. for the first time, while exploiting the knowledge of the local crust around the detector. The article will introduce the field and describe the key elements of the updated analysis. Geological interpretation and significance of the new result will be discussed in terms of the corresponding radiogenic heat and the limits to a hypothetical georeactor.
