description: We show that a violation of the Clauser-Horne-Shimony-Holt (CHSH) inequality can be demonstrated in a certain kind of Bell experiment for all bipartite entangled states. Our protocol allows local filtering measurements and involves shared ancilla states that do not themselves violate CHSH. Our result follows from two main steps. We first provide a simple characterization of the states that violate the CHSH-inequality after local filtering operations in terms of witness-like operators. Second, we prove that for each entangled state $σ$, there exists another state $ρ$ not violating CHSH, such that $ρ\otimesσ$ violates CHSH. Hence, in this scenario, $σ$ cannot be substituted by classical correlations without changing the statistics of the experiment; we say that $σ$ is not simulable by classical correlations and our result is that entanglement is equivalent to non-simulability.

description: This research attempts to describe the verbal and non-verbal behavior of educators and students and how they can contribute together to the promotion of empathy. In particular, this study consists of two parts. The first part, consisting of three chapters, takes a theoretical approach to the subject of the study. Thus, the concepts of communication and empathy, which are central to the subject under discussion, are analyzed and discussed in theory, with a particular emphasis on communication within the classroom. In the second part the empirical approach to the subject of the study is made. Specifically, we present the teaching observation made in a first grade elementary school in the Prefecture of Attica and the subsequent teaching intervention, with a focus on communication, verbal and non-verbal, and cultivation of empathy. The paper concludes by referring to the limitations and extensions that this particular research might have and by citing the literature

description: This roundtable session held at the 2019 meeting of the American Association of Religious Studies explores how decolonial analytics and praxis can be applied productively in Tibetan/Buddhist Studies. As scholars, it is critical for us to consider how the racialized perceptions of non-Western religious traditions and peoples are tethered to their continued structural dispossession. A decolonizing intervention here means making the material hierarchies among peoples and their knowledge systems legible but also interrogating the politics of knowledge production in light of these overlapping colonial histories. Our discussion explicitly explores how our choices as scholars have effects in the real world, including how we represent Tibet and the Himalayas/Buddhism in our publications and teaching, the current inequalities of access to academic capital for Tibetan and nonwhite students/scholars, etc. We draw from Indigenous Studies approaches that center Indigenous knowledges and voices, given the history of their marginalization and ask how can we better center Tibetan/Himalayan voices/epistemologies in the study of Tibetan Buddhism.

description: Superheavy particles are a natural candidate for the dark matter in the universe and our galaxy, because they are produced generically during inflation in cosmologically interesting amounts. The most attractive model for the origin of superheavy dark matter (SHDM) is gravitational production at the end of inflation. The observed cosmological density of dark matter determines the mass of the SHDM particle as $m_X=$(a few)$\:\times 10^{13}$ GeV, promoting it to a natural candidate for the source of the observed ultra-high energy cosmic rays (UHECR). After a review of the theoretical aspects of SHDM, we up-date its predictions for UHECR observations: no GZK cutoff, flat energy spectrum with $dN/dE\approx 1/E^{1.9}$, photon dominance and galactic anisotropy. We analyze the existing data and conclude that SDHM as explanation for the observed UHECRs is at present disfavored but not yet excluded. We calculate the anisotropy relevant for future Auger observations that should be the conclusive test for this model. Finally, we emphasize that negative results of searches for SHDM in UHECR do not disfavor SHDM as a dark matter candidate. Therefore, UHECRs produced by SHDM decays and with the signatures as described should be searched for in the future as subdominant effect.

description: The present thesis presents an action research that was implemented during my participation in the European Voluntary Service (EVS), as a volunteer at a public kindergarten, which was situtated in Wrocław, Poland. The purpose of this paper is to investigate what kind of intercultural teaching practices a teacher can apply in a foreign-language working environment. The approach was a qualitative one and the research questions that arose were: (a) What daily practices can a teacher use? (b) What kind of activities can he/she apply? (c) What problems can he/she face? (d) Which factors enhance the interaction and communication between the participants of the research? The method of triangulation was implemented, using diary, participatory observation and interviews. The data were analyzed using the method of quality content analysis. The thesis was theoretically based on intercultural teaching practices and its principles

description: Ένα από τα βασικά γνωρίσματα του ιδιωτικού δικαίου είναι η ελεύθερη ανάπτυξη της πρωτοβουλίας των κοινωνών αυτού. Υπάρχουν, ωστόσο, πτυχές της ιδιωτικής ζωής, η ρύθμιση των οποίων δεν είναι δυνατόν να αφεθεί αποκλειστικά στην ιδιωτική πρωτοβουλία όχι μόνο εξαιτίας του αντίκτυπου που αυτές έχουν στο κοινωνικό σύνολο αλλά και λόγω του ότι η προστασία αυτών έχει τεθεί υπό την εγγύηση του Κράτους. Χαρακτηριστικό παράδειγμα προς αυτή την κατεύθυνση αποτελεί η περίπτωση της κακής άσκησης της γονικής μέριμνας από τους φορείς αυτής, η οποία, μάλιστα, ενόψει του ότι συνιστά σοβαρή εκτροπή από την κανονικότητα της λειτουργίας της σχέσης μεταξύ γονέα και τέκνου είναι πολύ πιθανό να θέτει σε κίνδυνο την υγεία ή ακόμη και την ίδια τη ζωή του τέκνου. Αντικείμενο, λοιπόν, της παρούσας εργασίας είναι η σκιαγράφηση του βασικού πλαισίου των μέτρων που προβλέπει η νομοθεσία για την αντιμετώπιση των συνεπειών της κακής άσκησης της γονικής μέριμνας από τους φορείς αυτής. Ειδικότερα, στο Α΄ Μέρος της παρούσης γίνεται αναφορά στην έννοια, τη νομική φύση, τους φορείς, το περιεχόμενο, τη διάρκεια και την άσκηση της γονικής μέριμνας, στη συνέχεια στο Β΄ Μέρος παρατίθενται η έννοια της κακής άσκησης της γονικής μέριμνας και οι διάφορες μορφές αυτής, ενώ στο Γ’ Μέρος αναλύονται λεπτομερώς οι διάφορες δυνατότητες ένδικης προστασίας, έτσι όπως αυτές διαμορφώνονται ειδικότερα από το νόμο και την νομολογία με σκοπό τη διασφάλιση του συμφέροντος του τέκνου αλλά και της ίδιας της οικογένειας
description: One of the main characteristics of the private law is the uninhibited development of the initiative of its partakers. There are, however, aspects of the private life the regulation of which cannot solely rely on private initiative not only because of the impact that they have on society as a whole but also because their protection is guaranteed by the State. A typical example towards this direction is the bad exercise of parental responsibility by its agents, which, given that it constitutes a serious deviation from the normal function of the parent-child relationship, is very likely to place the child’s health or even life at risk. Τhe purpose of the present paper is therefore to outline the basic framework of the measures that legislation provides in order to adress the consequences of the bad exercise of parental responsibility by its agents. More specifically, in the first part of the paper, are cited the concept, the legal nature, the agents, the content, the duration and the exercise of parental responsibility. Consequently in the second part, the concept of bad exercise of parental responsibility and its various forms are being expanded, while in the third part are analyzed in detail the different alternatives for legal protection, as they are determined by the law and case-law to safeguard the interest of the child and the family itself
Trace analysis of protocols based on formal concurrent specifications
Creators: name: Kim, Myungchul
Publisher: name: University of British Columbia
Year: 2008

description: To increase the probability of computers communicating reliably with one another, protocol implementations must be tested for conformance to the standards on which they are based. Test case generation and trace analysis are two important topics in protocol testing research. Most of the work so far has focused on test case generation rather than trace analysis. Furthermore, most of the work has dealt only with the sequential aspects of the protocol specifications. In this thesis, a model that combines the two functions of test case generation and trace analysis in a unified framework is presented. The model, which is based on single module extended finite state machines, handles both control and data flows for single module specifications. Symbolic evaluation is used to detect and delete infeasible paths that may be generated. Practical considerations which may occur in a real test environment, such as out of order message sequences, are also addressed. A prototype implementation of the unified model was completed. The application of this method to X.25 LAPB shows that it can manage frame collision and control and data flows of the protocol rigorously. The model is extended to study the trace analysis of concurrent specifications based on multi-module extended finite state machines. This is done by introducing two additional models- concurrency and traceability. The concurrency model deals with concurrent properties such as concurrent events, concurrency blocks, global states, concurrency measures, deadlocks and data races which do not arise in sequential or single module specifications. The concurrency model allows a high-level abstraction to be used for understanding and analyzing concurrent behaviors. We also show how concurrency measures can be computed efficiently based on the concept of concurrency blocks. The traceability concept is needed to obtain the precise order of input/output messages of a module without state space explosion. This model for the trace analysis of concurrent specifications without translating them into their sequential equivalence is formalized and proposed for application to multi-module specification, multi-party testing and interoperability testing. The viability of the proposed methodology which can be applied to any specifications based on extended finite state machines is demonstrated using Estelle specifications in the thesis.

description: We present new results of the backscattering dominated prompt emission model in which the photons generated through pair annihilation at the centre of a gamma ray burst (GRB) are backscattered through Compton scattering by an outflowing stellar cork. %We show that the produced spectral features are capable of producing spectral features that are widely observed in GRBs. Using Comptonized pair annihilation spectrum accompanied by bremsstrahlung radiation for seed photons, we show that the obtained spectra produce low energy photon index in the range $α\sim -1.95$ to $-1.1$, steeper high energy slopes $β\sim -3.5$ to $-2.4$ and spectral peak energies $\sim$ few KeV to few $10\times$ MeV. These findings are consistent with the values covered in GRB prompt phase observations.

The frequency of planets in multiple systems

description: The frequency of planets in binaries is an important issue in the field of extrasolar planet studies, because of its relevance in estimating of the global planet population of our Galaxy and the clues it can give to our understanding of planet formation and evolution. However, only preliminary estimates are available in the literature. We analyze and compare the frequency of planets in multiple systems to the frequency of planets orbiting single stars. We also try to highlight possible connections between the frequency of planets and the orbital parameters of the binaries (such as the periastron and mass ratio.) A literature search was performed for binaries and multiple systems among the stars of the sample with uniform planet detectability defined by Fischer & Valenti (2005), and 202 of the 850 stars of the sample turned out to be binaries, allowing a statistical comparison of the frequency of planets in binaries and single stars and a study of the run of the planet frequency as a function of the binary separation. We found that the global frequency of planets in the binaries of the sample is not statistically different from that of planets in single stars. Even conservatively taking the probable incompleteness of binary detection in our sample into account, we estimate that the frequency of planets in binaries can be no more than a factor of three lower than that of planets in single stars. There is no significant dependence of planet frequency on the binary separation, except for a lower value of frequency for close binaries. However, this is probably not as low as required to explain the presence of planets in close binaries only as the result of modifications of the binary orbit after the planet formation.

description: The INvestigating Stellar Population In RElics is an on-going project targeting 52 ultra-compact massive galaxies at 0.12) through a short and intense star formation burst, that evolved passively and undisturbed until the present-day. Relics provide a unique opportunity to study the mechanisms of star formation at high-z. In this paper, we present the first INSPIRE Data Release, comprising 19 systems with observations completed in 2020. We use the methods already presented in the INSPIRE Pilot, but revisiting the 1D spectral extraction. For these 19 systems, we obtain an estimate of the stellar velocity dispersion, fitting separately the two UVB and VIS XSH arms at their original resolution. We estimate [Mg/Fe] abundances via line-index strength and mass-weighted integrated stellar ages and metallicities with full spectral fitting on the combined spectrum. Ages are generally old, in agreement with the photometric ones, and metallicities are almost always super-solar, confirming the mass-metallicity relation. The [Mg/Fe] ratio is also larger than solar for the great majority of the galaxies, as expected. We find that 10 objects have formed more than 75% of their stellar mass (M*) within 3 Gyr from the Big Bang and classify them as relics. Among these, we identify 4 galaxies which had already fully assembled their M* by that time. They are therefore `extreme relics' of the ancient Universe. The INSPIRE DR1 catalogue of 10 known relics to-date augment by a factor of 3.3 the total number of confirmed relics, also enlarging the redshift window. It is therefore the largest publicly available collection. Thanks to the larger number of systems, we can also better quantify the existence of a 'degree of relicness', already hinted at the Pilot Paper.

description: Vectorlike quarks have been shown to resolve certain long-standing discrepancies pertaining to the bottom sector. We investigate, here, the prospects of identifying the existence of a topless vectorlike doublet $(B,~Y)$, as is preferred by the electroweak precision measurements. Concentrating on single production, $viz.$ $B \bar b$ with $B \to b + Z/H$ subsequently, we find that the fully hadronic decay-channel is susceptible to discovery provided jet substructure observables are used. At the 13 TeV LHC with an integrated luminosity of 300 fb$^{-1}$, a modest value of the chromomagnetic transition moments allows for the exclusion of $M \lesssim 1.8(2.2)$ TeV in the $Z$ and $H$ channels respectively.

description: We calculate the vector form factor in K \to πl νsemileptonic decays at zero momentum transfer f_+(0) from numerical simulations of two-flavor QCD on the lattice. Our simulations are carried out on 16^3 \times 32 at a lattice spacing of a \simeq 0.12 fm using a combination of the DBW2 gauge and the domain-wall quark actions, which possesses excellent chiral symmetry even at finite lattice spacings. The size of fifth dimension is set to L_s=12, which leads to a residual quark mass of a few MeV. Through a set of double ratios of correlation functions, the form factor calculated on the lattice is accurately interpolated to zero momentum transfer, and then is extrapolated to the physical quark mass. We obtain f_+(0)=0.968(9)(6), where the first error is statistical and the second is the systematic error due to the chiral extrapolation. Previous estimates based on a phenomenological model and chiral perturbation theory are consistent with our result. Combining with an average of the decay rate from recent experiments, our estimate of f_+(0) leads to the Cabibbo-Kobayashi-Maskawa (CKM) matrix element |V_{us}|=0.2245(27), which is consistent with CKM unitarity. These estimates of f_+(0) and |V_{us}| are subject to systematic uncertainties due to the finite lattice spacing and quenching of strange quarks, though nice consistency in f_+(0) with previous lattice calculations suggests that these errors are not large.

description: It is common knowledge that we live in a world ruled by fear, violence, racism, xenophobia, intolerance and many other extreme events. The arising result of all these is a society on the edge of exhaustion, a society that is intensively flirting with fascism and indignant violence. The aim of this dissertation is to examine the crisis of Democracy and its values. By focusing on the case of Greece in the period of the recent financial crisis, the potential risks and threats towards Democracy are being exposed. Furthermore, unpleasant situations like the crisis of political representation, the unstable political reality, the extremely high unemployment rates, the anger and disappointment of Greek people and the overall feeling of insecurity that dominates the lives and choices of Greek citizens, are the reference points of this research. Under these circumstances important questions seem to arise. What is the role that Journalism plays in the reflection and the mediation of this political reality? Can Journalism still gain the trust of the people and affect public opinion? And finally, can Journalism contribute to the defense of the most vulnerable achievement of human race, Democracy?

This is accomplished by positioning the dots' energy levels such that a predetermined distribution of heat currents is realized across the chain in the steady state. The number of electrons in each cavity is conserved in the steady state which constrains the cavities' chemical potentials. We determine these chemical potentials analytically in the linear response regime where the energy differences between the dots' resonant levels and the neighboring chemical potentials are much smaller than the thermal energy. In this regime, the thermal control problem can be solved exactly, while, in the general case, thermal control can only be achieved in a relative sense, that is, when one only preassigns the ratios between different heat currents. We apply our results to two different cases: We first demonstrate that a "heat switch" can be easily realized with three coupled cavities, then we show that our linear response results can provide accurate results in situations with a large number of cavities.

description: Η παρούσα διπλωματική εργασία, χρησιμοποιώντας ως σώμα υλικού τον πρώτο κύκλο (δέκα επεισόδια) της τηλεοπτικής σειράς κινουμένων σχεδίων Απογοήτευση (Disenchantment) του Matt Groening, παραγωγή της διαδικτυακής πλατφόρμας Netflix και ως θεωρητικό πλαίσιο τις Περιγραφικές Μεταφραστικές Σπουδές (Toury, 1995) (Pedersen, 2011), και συγκεκριμένα την οπτικοακουστική μετάφραση, ασχολείται με τη συγκριτική ανάλυση της απόδοσης των ανθρωπωνυμίων στα ελληνικά, τα ισπανικά Ισπανίας και τα ισπανικά Λατινικής Αμερικής. Τα ανθρωπωνύμια που εντοπίζονται, κατηγοριοποιούνται με βάση το σημασιολογικό τους επίπεδο και έπειτα εξετάζονται οι μεταφραστικές στρατηγικές που επιλέγονται σε κάθε περίπτωση καθώς και τα μεταφραστικά αποτελέσματα τα οποία παρατηρούνται στις τρεις διαφορετικές εκδοχές. Στόχος είναι να μελετηθούν, όσο αυτό καθίσταται δυνατό, τα αίτια που οδήγησαν στις συγκεκριμένες μεταφραστικές επιλογές αλλά και σε ποιο βαθμό η γλωσσική πολιτική της Netflix τις επηρεάζει
description: The present master thesis using as a reference corpus the first season (ten episodes) of Matt Groening’s animated series Disenchantment, a production of the TV platform Netflix and as a theoretical framework the Descriptive Translation Studies (Toury, 1995) (Pedersen, 2011) and specifically the audiovisual translation, deals with the comparative study of the anthroponyms’ rendering in Greek, Spanish of Spain and of Latin America. Initially, I categorize the detected anthroponyms according to their semantic level and then I study the translational strategies which were used in each case and the translational results which I observe in the three different versions. My goal is to study, as far as possible, the reasons that led to these specific translational choices and to what degree Netflix’s linguistic policy affects them
description: Este trabajo de fin de master se basa en la primera temporada de la serie animada de televisión Disenchantment de Matt Groening, una producción de la plataforma de televisión Netflix y usa como marco teórico los Estudios Descriptivos de Traducción (Toury, 1995) (Pedersen, 2011) y específicamente la traducción audiovisual, y se centra en el análisis comparativo de las traducciones de los antropónimos en griego, castellano y español de América Latina. Los antropónimos que hemos identificado los hemos clasificado en categorías en función de su nivel semántico y a continuación hemos estudiado las estrategias de traducción que eran usadas en cada caso y los resultados de traducción que hemos observado en las tres versiones diferentes. El objetivo de este estudio es analizar, dentro de lo posible, los motivos que han llevado a estas decisiones de traducción y la manera en que se han visto determinadas por la política lingüística de Netflix
Models with Quartic Potential of Dynamical SUSY Breaking in Meta-Stable Vacua

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

description: We search for models of dynamical SUSY breaking in meta-stable vacua which might have dual string descriptions with a few brane probes. Two models with quartic superpotential are proposed: One of them might be closely related to the dual gauge theory to the flavored Maldacena-Nunez geometry by Casero, Nunez, and Paredes with a few additional brane probes corresponding to massive flavors. The other model might be dual to the Klebanov-Strassler geometry with one fractional D3-brane and a few D7-branes as probes.

description: We consider the application of a Fleischer$-$Jegerlehner-like treatment of tadpoles to the calculation of neutral scalar masses (including the Higgs) in general theories beyond the Standard Model. This is especially useful when the theory contains new scalars associated with a small expectation value, but comes with its own disadvantages. We show that these can be overcome by combining with effective field theory matching. We provide the formalism in this modified approach for matching the quartic coupling of the Higgs via pole masses at one loop, and apply it to both a toy model and to the $μ$NMSSM as prototypes where the standard treatment can break down.

description: Pressurized elastic shells are ubiquitous in nature and technology, from the outer walls of yeast and bacterial cells to artificial pressure vessels. Indentation measurements simultaneously probe the internal pressure and elastic properties of thin shells, and serve as a useful tool for strength testing and for inferring internal biological functions of living cells. We study the effects of geometry and pressure-induced stress on the indentation stiffness of ellipsoidal and cylindrical elastic shells using shallow-shell theory. We show that the linear indentation response reduces to a single integral with two dimensionless parameters that encode the asphericity and internal pressure. This integral can be numerically evaluated in all regimes and is used to generate compact analytical expressions for the indentation stiffness in various regimes of technological and biological importance. Our results provide theoretical support for previous scaling and numerical results describing the stiffness of ellipsoids, reveal a new pressure scale that dictates the large-pressure response, and give new insights to the linear indentation response of pressurized cylinders.

description: Σκοπός της συστηματικής ανασκόπησης είναι η ανίχνευση συσχέτισης των επιπέδων μαγνησίου ορού με τη νοσηρότητα και τη θνητότητα ασθενών με καρδιακή ανεπάρκεια. Μεθοδολογία: Η επιλογή των μελετών έγινε μετά από αναζήτηση σχετικών άρθρων στις ηλεκτρονικές βάσεις δεδομένων Pubmed και Scopus. Η αξιολόγηση της ποιότητας των επιλεγμένων μελετών διενεργήθηκε με βάση τα κριτήρια ποιότητας QUIPS tool. Αποτελέσματα: Οκτώ μελέτες κρίθηκαν κατάλληλες για τη συστηματική ανασκόπηση, στις οποίες περιλαμβάνονται 8651 ασθενείς με καρδιακή ανεπάρκεια με χαμηλό κλάσμα εξώθησης. Στο 50% των μελετών, η υπομαγνησιαιμία θεωρείται ανεξάρτητος προγνωστικός παράγοντας για την καρδιαγγειακή θνητότητα, συμπεριλαμβανομένου του αιφνίδιου θανάτου. Σε μία μελέτη μόνο, επίπεδα μαγνησίου >2,4mg/dl αποτελούν ανεξάρτητο προγνωστικό παράγοντα θνητότητας μη καρδιαγγειακής αιτιολογίας, ενώ δεν αποδεικνύεται στατιστικά σημαντική συσχέτιση των επιπέδων μαγνησίου ορού με τη νοσηρότητα ασθενών με καρδιακή ανεπάρκεια. Συμπέρασμα: Οι ασθενείς με καρδιακή ανεπάρκεια που εμφανίζουν υπομαγνησιαιμία σχετίζονται εν μέρει με αυξημένη καρδιαγγειακή θνητότητα, συμπεριλαμβανομένου του αιφνιδίου θανάτου
description: The purpose of the systematic review is the detection of the association of serum magnesium on mortality and morbidity in Heart Failure patients. Methods: The selection of the studies was based on searching in the data bases, Pubmed and Scopus. The assessment of the quality of the selected studies was accomplished according to validated quality criteria in prognostic studies (QUIPS tool). Results: Eight studies were considered appropriate for participating in the systematic review, which include 8651 Heart Failure patients with low LVEF (left ventricular ejection fraction). In half studies, hypomagnesemia is considered to be independent prognostic factor for cardiovascular mortality, including sudden death. Only in one study do magnesium levels > 2.4 mg/dl comprise independent prognostic factor for all cause mortality, whilst there is no statistical association of serum magnesium on morbidity outcomes in Heart Failure patients. Conclusion: Heart failure patients who develop hypomagnesemia are partially associated with increased cardiovascular mortality, including sudden death
The scaling attractor and ultimate dynamics for Smoluchowski's coagulation equations

description: We describe a basic framework for studying dynamic scaling that has roots in dynamical systems and probability theory. Within this framework, we study Smoluchowski's coagulation equation for the three simplest rate kernels $K(x,y)=2$, $x+y$ and $xy$. In another work, we classified all self-similar solutions and all universality classes (domains of attraction) for scaling limits under weak convergence (Comm. Pure Appl. Math 57 (2004)1197-1232). Here we add to this a complete description of the set of all limit points of solutions modulo scaling (the scaling attractor) and the dynamics on this limit set (the ultimate dynamics). The main tool is Bertoin's Lévy-Khintchine representation formula for eternal solutions of Smoluchowski's equation (Adv. Appl. Prob. 12 (2002) 547--64). This representation linearizes the dynamics on the scaling attractor, revealing these dynamics to be conjugate to a continuous dilation, and chaotic in a classical sense. Furthermore, our study of scaling limits explains how Smoluchowski dynamics ``compactifies'' in a natural way that accounts for clusters of zero and infinite size (dust and gel).
Geometrical Structures of Space-Time in General Relativity

description: Space-Time in general relativity is a dynamical entity because it is subject to the Einstein field equations. The space-time metric provides different geometrical structures: conformal, volume, projective and linear connection. A deep understanding of them has consequences on the dynamical role played by geometry. We present a unified description of those geometrical structures, with a standard criterion of naturalness, and then we establish relationships among them and try to clarify the meaning of associated geometric magnitudes.

description: Brightness-temperature fluctuations in the redshifted 21-cm background from the cosmic dark ages are generated by irregularities in the gas-density distribution and can then be used to determine the statistical properties of density fluctuations in the early Universe. We first derive the most general expansion of brightness-temperature fluctuations up to second order in terms of all the possible sources of spatial fluctuations. We then focus on the three-point statistics and compute the angular bispectrum of brightness-temperature fluctuations generated prior to the epoch of hydrogen reionization. For simplicity, we neglect redshift-space distortions. We find that low-frequency radio experiments with arcmin angular resolution can easily detect non-Gaussianity produced by non-linear gravity with high signal-to-noise ratio. The bispectrum thus provides a unique test of the gravitational instability scenario for structure formation, and can be used to measure the cosmological parameters. Detecting the signature of primordial non-Gaussianity produced during or right after an inflationary period is more challenging but still possible. An ideal experiment limited by cosmic variance only and with an angular resolution of a few arcsec has the potential to detect primordial non-Gaussianity with a non-linearity parameter of f_NL ~ 1. Additional sources of error as weak lensing and an imperfect foreground subtraction could severely hamper the detection of primordial non-Gaussianity which will benefit from the use of optimal estimators combined with tomographic techniques.
