description: Small cell networks with dynamic time-division duplex (D-TDD) have emerged as a potential solution to address the asymmetric traffic demands in 5G wireless networks. By allowing the dynamic adjustment of cell-specific UL/DL configuration, D-TDD flexibly allocates percentage of subframes to UL and DL transmissions to accommodate the traffic within each cell. However, the unaligned transmissions bring in extra interference which degrades the potential gain achieved by D-TDD. In this work, we propose an analytical framework to study the performance of multi-antenna small cell networks with clustered D-TDD, where cell clustering is employed to mitigate the interference from opposite transmission direction in neighboring cells. With tools from stochastic geometry, we derive explicit expressions and tractable tight upper bounds for success probability and network throughput. The proposed analytical framework allows to quantify the effect of key system parameters, such as UL/DL configuration, cluster size, antenna number, and SINR threshold. Our results show the superiority of the clustered D-TDD over the traditional D-TDD, and reveal the fact that there exists an optimal cluster size for DL performance, while UL performance always benefits from a larger cluster.

description: An overview of game-theoretic approaches to energy-efficient resource allocation in wireless networks is presented. Focusing on multiple-access networks, it is demonstrated that game theory can be used as an effective tool to study resource allocation in wireless networks with quality-of-service (QoS) constraints. A family of non-cooperative (distributed) games is presented in which each user seeks to choose a strategy that maximizes its own utility while satisfying its QoS requirements. The utility function considered here measures the number of reliable bits that are transmitted per joule of energy consumed and, hence, is particulary suitable for energy-constrained networks. The actions available to each user in trying to maximize its own utility are at least the choice of the transmit power and, depending on the situation, the user may also be able to choose its transmission rate, modulation, packet size, multiuser receiver, multi-antenna processing algorithm, or carrier allocation strategy. The best-response strategy and Nash equilibrium for each game is presented. Using this game-theoretic framework, the effects of power control, rate control, modulation, temporal and spatial signal processing, carrier allocation strategy and delay QoS constraints on energy efficiency and network capacity are quantified.

description: Molte sono le accezioni del termine “mobilità”. In ambito sociologico si parla di mobilità sociale. In ambito economico di quella dei capitali. Nel nostro ambiente accademico, in ambito Erasmus o di scambi istituzionali, si è diffusa la mobilità studentesca e quella dei docenti e dei ricercatori.

Il libro di De Vecchis, Geografia delle mobilità. Muoversi e viaggiare in un mondo globale, ragiona di questo e altro, ma ne ragiona in un modo diverso da quanto fanno i più diffusi manuali di geografia, o di quanto si può leggere in capitoli di manuali di antropologia, o di storia.

Il "poggio delle mortelle" nella storia dell'architettura napoletana

description: Il  “poggio delle Mortelle” è una piccola area a sud-ovest della collina di San Martino, aperta sul mare in direzione di Posillipo e  celebrata dai cronisti per la bellezza del sito e la salubrità dell’aria. La sua storia riassume le vicende urbanistiche di Napoli durante l’età vicereale: inserita nel XVI secolo all'interno della murazione cittadina dal viceré Pedro de Toledo, la zona si caratterizzò inizialmente come zona di piccoli conventi e di ville “di delizie”; la morfologia accidentata dei luoghi e l’intenso sviluppo edilizio, perseguito per tutto il secolo successivo dagli ordini religiosi e dai rappresentanti dei ceti emergenti ne provocarono prima la crescita disordinata, poi, in età barocca, la fortuna come zona residenziale.
Celebrata da vedutisti e letterati come una delle più belle zone della città, la contrada delle Mortelle perse nell’Ottocento le connotazioni originarie: la rete degli antichi tracciati viari fu distrutta dall’apertura del corso Vittorio Emanuele, mentre gli edifici più rappresentativi vennero stravolti da interventi per nulla rispettosi delle peculiarità legate alla destinazione originaria. Tuttavia il quartiere ha conservato buona parte delle architetture antiche, che permettono tuttora di leggerne la stratificazione.

description: We test the validity of the QCD sum rules applied to the meson $Z^+(4430)$, by considering a diquark-antidiquark type of current with $J^{P}=0^{-}$ and with $J^{P}=1^{-}$. We find that, with the studied currents, it is possible to find an acceptable Borel window. In such a Borel window we have simultaneously a good OPE convergence and a pole contribution which is bigger than the continuum contribution. We get $m_Z=(4.52\pm0.09)\GeV$ and $m_Z=(4.84\pm0.14)\GeV$ for the currents with $J^{P}=0^{-}$ and $J^{P}=1^{-}$ respectively. We conclude that the QCD sum rules results favors $J^{P}=0^{-}$ quantum numbers for the $Z^+(4430)$ meson.

description: Motivated by growing applications in two-sided markets, we study a parallel matching queue with reneging. Demand and supply units arrive to the system and are matched in an FCFS manner according to a compatibility graph specified by an N-system. If they cannot be matched upon arrival, they queue and may abandon the system as time goes by. We derive explicit product forms of the steady state distributions of this system by identifying a partial balance condition.

description: It is often claimed that the theory of function levels proposed by Frege in Grundgesetze der Arithmetik anticipates the hierarchy of types that underlies Church's simple theory of types. This claim roughly states that Frege presupposes a type of functions in the sense of simple type theory in the expository language of Grundgesetze. However, this view makes it hard to accommodate function names of two arguments and view functions as incomplete entities. I propose and defend an alternative interpretation of first-level function names in Grundgesetze into simple type-theoretic open terms rather than into closed terms of a function type. This interpretation offers a still unhistorical but more faithful type-theoretic approximation of Frege's theory of levels and can be naturally extended to accommodate second-level functions. It is made possible by two key observations that Frege's Roman markers behave essentially like open terms and that Frege lacks a clear criterion for distinguishing between Roman markers and function names.

description: Mediation of violent political conflicts in Africa: “A niche diplomacy” for Burkina Faso
One of the main obstacles to the development of African countries is the recurring presence of political conflicts of different intensity. After the fall of the Berlin Wall, the way to resolve conflicts has changed by favouring an approach closer to the mediation model. Specifically, in this article we will examine the idea of “niche diplomacy” linked in particular to the country’s international experience in neighbouring conflict theatres, in order to explain the strategic reasons of such mediation activity by outlining its potential and contradictions.

description: For the Szekeres system which describes inhomogeneous and anisotropic spacetimes we make use of a point-like Lagrangian, which describes the evolution of the physical variables of the Szekeres model, in order to perform a canonical quantization and to study the quantum potentiality of the Szekeres system in the content of de Broglie--Bohm theory. We revise previous results on the subject and we find that for a specific family of trajectories with initial conditions which satisfy a constraint equation, there exists additional conservation laws for the classical Szekeres system which are used to define differential operators and to solve the Wheeler-DeWitt equation. From the new conservation laws we construct a wave function which provides a nonzero quantum potential term that modifies the Szekeres system. The quantum potential corresponds to new terms in the dynamical system such that new asymptotic solutions with a nonzero energy momentum tensor of an anisotropic fluid exist. Therefore, the silent property of the Szekeres spacetimes is violated by quantum correction terms.

description: A game-theoretic framework is used to study the effect of constellation size on the energy efficiency of wireless networks for M-QAM modulation. A non-cooperative game is proposed in which each user seeks to choose its transmit power (and possibly transmit symbol rate) as well as the constellation size in order to maximize its own utility while satisfying its delay quality-of-service (QoS) constraint. The utility function used here measures the number of reliable bits transmitted per joule of energy consumed, and is particularly suitable for energy-constrained networks. The best-response strategies and Nash equilibrium solution for the proposed game are derived. It is shown that in order to maximize its utility (in bits per joule), a user must choose the lowest constellation size that can accommodate the user's delay constraint. This strategy is different from one that would maximize spectral efficiency. Using this framework, the tradeoffs among energy efficiency, delay, throughput and constellation size are also studied and quantified. In addition, the effect of trellis-coded modulation on energy efficiency is discussed.

description: Pulsar candidate sifting is an essential process for discovering new pulsars. It aims to search for the most promising pulsar candidates from an all-sky survey, such as High Time Resolution Universe (HTRU), Green Bank Northern Celestial Cap (GBNCC), Five-hundred-meter Aperture Spherical radio Telescope (FAST), etc. Recently, machine learning (ML) is a hot topic in pulsar candidate sifting investigations. However, one typical challenge in ML for pulsar candidate sifting comes from the learning difficulty arising from the highly class-imbalance between the observation numbers of pulsars and non-pulsars. Therefore, this work proposes a novel framework for candidate sifting, named multi-input convolutional neural networks (MICNN). The MICNN is an architecture of deep learning with four diagnostic plots of a pulsar candidate as its inputs. To train our MICNN in a highly class-imbalanced dataset, a novel image augment technique, as well as a three-stage training strategy, is proposed. Experiments on observations from HTRU and GBNCC show the effectiveness and robustness of these proposed techniques. In the experiments on HTRU, our MICNN model achieves a recall of 0.962 and a precision rate of 0.967 even in a highly class-imbalanced test dataset.

description: As radio telescopes become sensitive, radio frequency interference (RFI) is more and more serious for interesting signals of radio astronomy. There exist demands for developing an automatic, accurate and efficient RFI mitigation method. Therefore, this work investigated the RFI detection algorithm. Firstly, we introduced an Asymmetrically Reweighted Penalized Least Squares (ArPLS) method to estimate baseline more accurately. After removing the estimated baseline, several novel strategies were proposed based on the SumThreshold algorithm for detecting different types of RFI. The threshold parameter in the SumThreshold can be determined automatically and adaptively. The adaptiveness is essential for reducing human interventions and the online RFI processing pipeline. Applications to FAST (Five-hundred-meter Aperture Spherical Telescope) data show that the proposed scheme based on the ArPLS and SumThreshold is superior to some typically available methods for RFI detection with respect to efficiency and performance.

description: Lepton Flavour Violation(LFV) is New Physics that must occur, but is stringently constrained by experiments searching for mu to e flavour change, such as $μ\to e γ$, $μ\to 3e$ and $μ\to e$ conversion. However, in an Effective Field Theory(EFT) parametrisation, there are many more $μ\leftrightarrow e$ operators than restrictive constraints, so determining operator coefficients from data is a remote dream. It is nonetheless interesting to learn about New Physics from data, so this manuscript introduces "observable-vectors" in the space of operator coefficients, which identify at any scale the combination of coefficients probed by the observable. These vectors have at least partpermil overlap with most of the coefficients, and are used to study whether $μ\to e γ$, $μ\to 3e$ and $μ\to e$ conversion give complementary information about New Physics. The appendix gives updated sensitivities of these processes, (and a subset of LFV tau decays), to operator coefficients at the weak scale in the SMEFT and in the EFT below mW.

description: Flow cytometry is often used to characterize the malignant cells in leukemia and lymphoma patients, traced to the level of the individual cell. Typically, flow cytometric data analysis is performed through a series of 2-dimensional projections onto the axes of the data set. Through the years, clinicians have determined combinations of different fluorescent markers which generate relatively known expression patterns for specific subtypes of leukemia and lymphoma -- cancers of the hematopoietic system. By only viewing a series of 2-dimensional projections, the high-dimensional nature of the data is rarely exploited. In this paper we present a means of determining a low-dimensional projection which maintains the high-dimensional relationships (i.e. information) between differing oncological data sets. By using machine learning techniques, we allow clinicians to visualize data in a low dimension defined by a linear combination of all of the available markers, rather than just 2 at a time. This provides an aid in diagnosing similar forms of cancer, as well as a means for variable selection in exploratory flow cytometric research. We refer to our method as Information Preserving Component Analysis (IPCA).

description: Solvable structures, likewise solvable algebras of local symmetries, can be used to integrate scalar ODEs by quadratures. Solvable structures, however, are particularly suitable for the integration of ODEs with a lack of local symmetries. In fact, under regularity assumptions, any given ODE always admits solvable structures even though finding them in general could be a very difficult task. In practice a noteworthy simplification may come by computing solvable structures which are adapted to some admitted symmetry algebra. In this paper we consider solvable structures adapted to local and nonlocal symmetry algebras of any order (i.e., classical and higher). In particular we introduce the notion of nonlocal solvable structure.

description: Durante l’attività di ricerca si è tentato di fornire un contributo al miglioramento del livello di conoscenza del funzionamento degli MBR, cercando di colmare, almeno in parte, le lacune ch etale tecnologia ancora presenta. Tale fine è stato perseguito conducendo attività di diverso tipo: indagini sperimentali su due impianti pilota con differente tecnologia di filtrazione, allo scopo di poterne operare il raffronto; utilizzazione di due distinti modelli matematici, di cui il primo convenzionale, idoneo a simulare sistemi a fanghi attivi convenzionali, ed il secondo innovativo, specificamente messo a punto per il sistema MBR, in grado anche di correlare l’attività biologica allo sporcamento delle membrane; analisi di laboratorio, finalizzate sia alla stima dei parametri cinetici e stechiometrici della biomassa che alla caratterizzazione di quest’ultima dal punto di vista microbiologico e delle proprietà di disidratabilità.
Le sperimentazioni hanno mostrato peculiarità degli MBR ancora inesplorate e che potranno consentire un loro utilizzo anche per quei reflui considerati non trattabili biologicamente da un impianto convenzionale a fanghi attivi, facendo, quindi, intravedere nuovi campi di applicazione a tale sistema di trattamento delle acque reflue incrementandone, così, la crescita futura.
Relazione tra staminalità, deregolazione della compattazione cromatinica nucleare e potenzialità di aggressività biologica del melanoma cutaneo

description: Nonostante il progressivo incremento dei casi di melanoma maligno cutaneo diagnosticati precocemente, registrato negli ultimi vent’anni in seguito alla introduzione della demoscopia, gli indici di mortalità per questa neoplasia mostrano un andamento sostanzialmente invariato, a causa della sua frequente estrema aggressività, spesso indipendente dai tradizionali fattori prognostici, ed a causa della persistente assenza di cure realmente efficaci per il trattamento della malattia metastatica. Il tentativo di una accurata valutazione prognostica si scontra con la frequente imprevedibilità del comportamento biologico del melanoma, soprattutto in quelle lesioni (“area grigia”) con spessore intermedio (>1 mm, <2mm). La “stem cell theory” suggerisce che la derivazione dal compartimento staminale possa costituire un fattore determinante nell’induzione del fenotipo aggressivo di almeno un sottogruppo di melanomi cutanei. Il nostro studio si propone di indagare l’eventuale rapporto tra l’espressione di un marcatore di staminalità (nestina) ed i principali parametri clinico-patologici di valutazione prognostica di una serie di 129 pazienti, selezionata in base alla disponibilità dei dati completi di follow-up. I risultati dello studio verranno inoltre rapportati a quelli relativi all’espressione della proteina CAF-1/p60, direttamente coinvolta nella regolazione epigenetica della compattazione cromatinica, che in un nostro recente studio è risultata direttamente correlata con un comportamento aggressivo dei melanomi maligni cutanei. Lo scopo della ricerca è stato quello di valutare l’eventuale ruolo di queste molecole come markers predittivi di prognosi e possibili targets per terapia molecolare.

description: A recent article in Nature Physics unified key results from thermodynamics, statistics, and information theory. The unification arose from a general equation for the rate of change in the information content of a system. The general equation describes the change in the moments of an observable quantity over a probability distribution. One term in the equation describes the change in the probability distribution. The other term describes the change in the observable values for a given state. We show the equivalence of this general equation for moment dynamics with the widely known Price equation from evolutionary theory, named after George Price. We introduce the Price equation from its biological roots, review a mathematically abstract form of the equation, and discuss the potential for this equation to unify diverse mathematical theories from different disciplines. The new work in Nature Physics and many applications in biology show that this equation also provides the basis for deriving many novel theoretical results within each discipline.
The role of autophagy in neoplastic cell response to oncolytic viruses
Creators: name: Botta, Ginevra
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2009

description: Oncolytic conditionally replicating adenoviruses (CRAds) are viral mutants able to selectively replicate in tumour cells. CRAds are considered a promising platform for cancer therapy. dl922-947, bearing a mutation in E1A gene and AdΔΔ, carrying mutations in both E1A and E1B genes, exhibited an antitumour effect against glioma and prostate cancer cells, respectively. Recently, it is thought that the adequate modulation of autophagy can enhance efficacy of anticancer therapy. However, the outcome of autophagy manipulation depends on the autophagy initiator, the combined stimuli, the extent of cellular damage and the type of cells. In this study, I characterized the role of autophagy in oncolytic adenovirus-induced therapeutics effects. When autophagy was inhibited at different steps by chloroquine (HCQ) or 3-methyladenine (3-MA), the cytotoxicity of dl922-947 and AdΔΔ in glioma and prostate cancer cells was augumented. These findings indicate that autophagy is a cell survival response in infected cells. Moreover, I showed that the oncolytic adenoviruses activated the Akt/mTOR/p70s6k pathway, that plays a central role in the negative regulation of autophagy, and, accordingly, inhibited the ERK pathway, that is a positive regulator of autophagy. Interestingly, a MEK inhibitor, PD98059, synergistically sensitized glioma cells to dl922-947 by increasing autophagy inhibition. These findings suggest that a disruption of ERK signalling pathway could greatly enhance the efficacy of CRAds by inhibiting autophagy. The observation that autophagy inhibitors increase adenoviruses antitumor activity in cancer cells suggests a novel multimodal strategy for virotherapy.

description: В статье приведен анализ экстремальных погодных условий, отрицательно вли-яющих на полевые культуры. Рост и развитие озимой пшеницы тесно связаны с клима-тическими условиями среды, в которой она возделывается. Например, в начальной ста-дии всходов необходимы низкие температуры, полезные для их закаливания и успеш-ной перезимовки. Поэтому при выведении новых сортов необходимо учитывать такой показатель, как зимостойкость, позволяющий в зимний период переносить низкую температуру (до 15 °С) на узле кущения. Повреждения всходов озимой пшеницы в зимне-весенний период, вызванные низкими температурами, часто принимают за бо-лезни или действия вредителей. Губительным явлением для перезимовки всходов яв-ляются бесснежные зимы с продолжительными оттепелями, провоцирующие возобнов-ление вегетации. Резкое снижение температуры воздуха и замерзание почвы могут привести к стрессовым состояниям и гибели всходов озимой пшеницы. На ранних яро-вых культурах, в частности горохе, весенние заморозки также опасны и приводят к снижению продуктивности.
description: The article presents an analysis of extreme weather conditions that negatively affect field crops. The growth and development of winter wheat is closely related to the climatic conditions of the environment in which it is cultivated. Thus, in the initial phase of germina-tion, low temperatures are necessary, which are useful for their hardening and successful overwintering. Therefore, when breeding new varieties, it is necessary to take into account such an indicator as winter hardiness, which allows tolerating a low temperature at the tillering node up to – 15 °C in winter. During winter and spring, winter wheat seedlings damage caused by low temperatures is often mistaken for diseases or pests. A disastrous phenomenon for overwintering seedlings is snowless winters with prolonged thaws, which cause vegetative renewal. A rapid air temperature reduction and freezing of the soil can lead to stressful condi-tions and death of winter wheat seedlings. Spring frosts are also dangerous for early spring crops, such as peas. They lead to a decrease in productivity.

description: Cherenkov radiation may occur whenever the source is moving faster than the waves it generates. In a radiation dominated universe, with equation-of-state $w = 1/3$, we have recently shown that the Bardeen scalar-metric perturbations contribute to the linearized Weyl tensor in such a manner that its wavefront propagates at acoustic speed $\sqrt{w}=1/\sqrt{3}$. In this work, we explicitly compute the shape of the Bardeen Cherenkov cone and wedge generated respectively by a supersonic point mass (approximating a primordial black hole) and a straight Nambu-Goto wire (approximating a cosmic string) moving perpendicular to its length. When the black hole or cosmic string is moving at ultra-relativistic speeds, we also calculate explicitly the sudden surge of scalar-metric induced tidal forces on a pair of test particles due to the passing Cherenkov shock wave. These forces can stretch or compress, depending on the orientation of the masses relative to the shock front's normal.

description: It is shown that the laws of thermodynamics are extremely robust under generalizations of the form of entropy. Using the Bregman-type relative entropy, the Clausius inequality is proved to be always valid. This implies that thermodynamics is highly universal and does not rule out consistent generalization of the maximum entropy method.

description: Supervised machine learning methods for image analysis require large amounts of labelled training data to solve computer vision problems. The recent rise of deep learning algorithms for recognising image content has led to the emergence of many ad-hoc labelling tools. With this survey, we capture and systematise the commonalities as well as the distinctions between existing image labelling software. We perform a structured literature review to compile the underlying concepts and features of image labelling software such as annotation expressiveness and degree of automation. We structure the manual labelling task by its organisation of work, user interface design options, and user support techniques to derive a systematisation schema for this survey. Applying it to available software and the body of literature, enabled us to uncover several application archetypes and key domains such as image retrieval or instance identification in healthcare or television.

Superradiant emission of a thermal atomic beam into an optical cavity

description: We theoretically analyze the collective dynamics of a thermal beam of atomic dipoles that couple to a single mode when traversing an optical cavity. For this setup we derive a semiclassical model and determine the onset of superradiant emission and its stability. We derive analytical expressions for the linewidth of the emitted light and compare them with numerical simulations. In addition, we find and predict two different superradiant phases; a steady-state superradiant phase and a multi-component superradiant phase. In the latter case we observe sidebands in the frequency spectrum that can be calculated using a stability analysis of the amplitude mode of the collective dipole. We show that both superradiant phases are robust against free-space spontaneous emission and $T_2$ dephasing processes.

Combining Observational and Experimental Data to Improve Efficiency Using Imperfect Instruments

description: Randomized controlled trials generate experimental variation that can credibly identify causal effects, but often suffer from limited scale, while observational datasets are large, but often violate desired identification assumptions. To improve estimation efficiency, I propose a method that leverages imperfect instruments - pretreatment covariates that satisfy the relevance condition but may violate the exclusion restriction. I show that these imperfect instruments can be used to derive moment restrictions that, in combination with the experimental data, improve estimation efficiency. I outline estimators for implementing this strategy, and show that my methods can reduce variance by up to 50%; therefore, only half of the experimental sample is required to attain the same statistical precision. I apply my method to a search listing dataset from Expedia that studies the causal effect of search rankings on clicks, and show that the method can substantially improve the precision.

I rapporti tra l'Unione Europea e la NATO
Creators: name: Cherillo, Alessia

description: Il presente lavoro di ricerca si propone di analizzare lo stato attuale delle relazioni tra l’Unione europea e la NATO  perseguendo  un duplice obiettivo: da un lato, l’analisi dei progressi compiuti negli ultimi anni in termini di meccanismi ed ambiti di cooperazione tra le due organizzazioni e dall’altro lo svisceramento delle problematiche ed i nodi politici irrisolti che ne ostacolano un’efficace attuazione.
L’analisi non prescinde dai mutamenti che lo scenario internazionale, nonché le organizzazioni stesse, ha subito soprattutto durante la fase successiva alla guerra fredda, fase in cui la natura sostanziale della NATO ha dovuto necessariamente tramutarsi sulla base di contingenze che  imponevano una rivalutazione della sua logica  di difesa. 
Ed è inevitabile approfondire il corollario di tali meccanismi evolutivi che si traduce in una diversa e più  concreta cooperazione tra l’Ue e la NATO.

Another Co*cryption Method

subject: F.1.1; E.3

description: We consider the enciphering of a data stream while being compressed by a LZ algorithm. This has to be compared to the classical encryption after compression methods used in security protocols. Actually, most cryptanalysis techniques exploit patterns found in the plaintext to crack the cipher; compression techniques reduce these attacks. Our scheme is based on a LZ compression in which a Vernam cipher has been added. We make some security remarks by trying to measure its randomness with statistical tests. Such a scheme could be employed to increase the speed of security protocols and to decrease the computing power for mobile devices.
Nonequilibrium transport and optical properties of model metal--Mott-insulator--metal heterostructures

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: Electronic properties of heterostructures in which a finite number of Mott-insulator layers are sandwiched by semi-infinite metallic leads are investigated by using the dynamical-mean-field method combined with the Keldysh Green's function technique to account for the finite bias voltage between the leads. Current across the junction is computed as a function of bias voltage. Electron spectral functions in the interacting region are shown to evolve by an applied bias voltage. This effect is measurable by photoemission spectroscopy and scanning tunneling microscopy. Further predictions are made for the optical conductivity under a bias voltage as a possible tool to detect a deformed density of states. A general discussion of correlated-electron based heterostructures and future prospect is given.

description: Using light-cone sum rule techniques, we estimate the form factors which parametrise the hadronic matrix elements that are relevant for semi-leptonic three-body proton decays. The obtained form factors allow us to determine the differential rate for the decay of a proton ($p$) into a positron ($e^+$), a neutral pion ($π^0$) and a graviton ($G$), which is the leading proton decay channel in the effective theory of gravitons and Standard Model particles (GRSMEFT). The sensitivity of existing and next-generation neutrino experiments in detecting the $p \to e^+ π^0 G$ signature is studied and the phenomenological implications of our computations for constraints on the effective mass scale that suppresses the relevant baryon-number violating GRSMEFT operator are discussed.
