A Quantum-Gravity Perspective on Semiclassical vs. Strong-Quantum Duality
Creators: name: Isidro, J. M.
Publisher: name: arXiv
Year: 2005
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: It has been argued that, underlying M-theoretic dualities, there should exist a symmetry relating the semiclassical and the strong-quantum regimes of a given action integral. On the other hand, a field-theoretic exchange between long and short distances (similar in nature to the T-duality of strings) has been shown to provide a starting point for quantum gravity, in that this exchange enforces the existence of a fundamental length scale on spacetime. In this letter we prove that the above semiclassical vs. strong-quantum symmetry is equivalent to the exchange of long and short distances. Hence the former symmetry, as much as the latter, also enforces the existence of a length scale. We apply these facts in order to classify all possible duality groups of a given action integral on spacetime, regardless of its specific nature and of its degrees of freedom.

description: The wet denitrification technology has a good development prospect due to its simple system and mild reaction conditions, and the related research has become a hot topic in the field of flue gas purification. In this work, a novel simultaneous removal technology of NO from flue gas using Fe2+/Cu2+-catalytic H2O2/(NH4)2S2O8 system was developed for the first time. The feasibility of this new flue gas cleaning technology was explored through a series of experiments and performance analysis. The mechanism of oxidation products, free radicals and simultaneous removal of NO was revealed. The effects of the main process parameters on the removal of NO were investigated. Relevant results demonstrated that removing efficiency of NO was elevated when concentration of (NH4)2S2O8 or reacting temperature increased, while it was decreased after increasing by the raising of Fe2+, Cu2+ and H2O2 concentrations. The main radicals was ·OH and·SO4-, using electron spin resonance technique in the solution, and played very important role in NO removal. The main products was carried out by ion chromatography and elemental N material accountancy, and the results showed that it was sulfate and nitrate in the solution, which provided theoretical guidance for the subsequent treatment and resource utilization of absorption solution. The results of the study provided a theoretical basis for the industrial application of wet denitrification.

description: We identify a new shot noise suppression mechanism in a thin (~100 nm) heterostructure avalanche photodiode. In the low-gain regime the shot noise is suppressed due to temporal correlations within amplified current pulses. We demonstrate in a Monte Carlo simulation that the effective excess noise factors can be <1, and reconcile the apparent conflict between theory and experiments. This shot noise suppression mechanism is independent of known mechanisms such as Coulomb interaction, or reflection at heterojunction interfaces.

A Close Look at the Population of Supersoft and Quasi-Soft X-Ray Sources Observed in M31 with XMM-Newton
Creators: name: Orio, M.
Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The deepest X-ray images of M31, obtained with XMM-Newton, are examined in this paper to derive spectral and statistical properties of the population of the softest X-ray sources. Classifying supersoft X-ray sources (SSS) with criteria based on the same hardness ratios defined for recent Chandra observations, a quarter of the selected SSS turn out to be supernova remnants (SNR). Another quarter of SSS are spatially coincident with recent classical novae (but they are less than 10% of the nova population observed in the last 25 years). Only 3 among 15 non-SNR SSS show clear time variability, with X-ray flux variation of more than one order of magnitude within few months. Two of these sources display additional, smaller amplitude variability on time scales of several minutes. Their broad band spectra and those of the novae are approximately fit with a blackbody or white dwarf atmospheric model at near-Eddington luminosity for the distance of M31. Two SSS appear to reach very large, perhaps super-Eddington luminosities for part of the time, and probably eject material in a wind until the luminosity decreases again after a few months. One of the two objects has some characteristics in common with Ultra Luminous X-ray Sources observed outside the Local Group. Most Quasi-Soft Sources (QSS) are repeatedly detected. I discuss the possibilities that most QSS may be SNR in M31, or foreground neutron stars. Two X-ray sources with both a soft and hard component are in the positions of a recurrent nova and another object that was tentatively classified as a symbiotic nova. These two sources may be black hole transients.

description: Cognitive radio is an intelligent and adaptive radio that improves the utilization of the spectrum by its opportunistic sharing. However, it is inherently vulnerable to primary user emulation and jamming attacks that degrade the spectrum utilization. In this paper, an algorithm for the detection of primary user emulation and jamming attacks in cognitive radio is proposed. The proposed algorithm is based on the sparse coding of the compressed received signal over a channel-dependent dictionary. More specifically, the convergence patterns in sparse coding according to such a dictionary are used to distinguish between a spectrum hole, a legitimate primary user, and an emulator or a jammer. The process of decision-making is carried out as a machine learning-based classification operation. Extensive numerical experiments show the effectiveness of the proposed algorithm in detecting the aforementioned attacks with high success rates. This is validated in terms of the confusion matrix quality metric. Besides, the proposed algorithm is shown to be superior to energy detection-based machine learning techniques in terms of receiver operating characteristics curves and the areas under these curves

description: The Uruguayan and New Zealand beef industries have developed under similar climatic conditions that favour pastoral farming. Both industries are export focused. However, the development paths taken by the two industries have been different. Porter's diamond is used as a framework for analysing the competitive strengths and weaknesses of each industry. It is concluded that the lower prices received by producers in the Uruguayan industry, linked historically to Uruguay's foot and mouth disease (FMD) status but now caused primarily by tariff issues in the North American market, have been a fundamental problem. This has led to different input-output ratios than have been experienced in New Zealand, and made investment based on intensification less attractive. The New Zealand industry has also benefited from deregulation, such that investors have been more willing to invest in the knowledge that their competitive position will be determined by market forces rather than by government behaviour. The key to the future prospects of the Uruguayan industry is by addressing the market access problems and the provision of a deregulated agribusiness environment. The challenge for the New Zealand industry is how to maintain and enhance its current position as other countries seek to copy and surpass its performance.

description: We investigate non-extremal D-instantons in an asymptotically $ AdS_5 \times S^5$ background and the role they play in the $ AdS_5 / CFT_4$ correspondence. We find that the holographic dual operators of non-extremal D-instanton configurations do not correspond to self-dual Yang-Mills instantons, and we compute explicitly the deviation from self-duality. Furthermore, a class of non-extremal D-instantons yield Euclidean axionic wormhole solutions with two asymptotic boundaries. After Wick rotating, this provides a playground for investigating holography in the presence of cosmological singularities in a closed universe.

description: Enterprise architecture (EA) has been present in scientific literature since the 1980s and has branched out into several research fields. EA delivers value by presenting business and ICT leaders with recommendations for adjusting policies and projects to achieve business goals. Although there are many works on the EA application in healthcare systems, the literature lacks studies that provide a systematic approach to this topic specifically. This work presents a deep and broad Systematic Literature Review (SLR) to select studies demonstrating current EA practices in healthcare systems. The researchers established an SLR protocol returning 280 primary studies after the first step of the Data Selection and a consolidated inclusion of 46 articles after the second step. They assessed the level of disagreement during the team's evaluations using Cohen's Kappa. This SLR revealed essential aspects of state-of-the-art EA application in healthcare systems, such as the most used methodologies and tools, best practices, and criteria considered for their choice. It also analyzed the main positive impacts, challenges, and critical success factors described by the studies' authors based on empirical approaches. Besides, this work brings the main publication channels and the most influential authors on the topic of EA in Healthcare systems.

description: This work compares the incomes of the rural families of the Southern Region of Brazil in the years of 1995 and 2001, using the special micro data tabulation of the National Sample Home Research (PNADs). The results show that the agricultural income is steady: the non - agricultural income has grown in some kinds of families; the pensions/retirement incomes have increased among the families in the universe of home agriculture; and the "other incomes" are irrelevant. It is inferred that low economical dynamism of the rural cities and the agricultural crisis led to agricultural income stagnation and also to an impoverishment process of the families. Thus, there is a need of redefining the public policies for the rural families concerning the diversity of incomes, as well as new sustainable mechanisms for the families in higher levels than the current ones.

UNITED STATES OF AMERICA – Mississippi • 229 teeth, MMNS VP-6995 (10 teeth), SC 2013.28.581 (Fig. 30A–C), SC 2013.28.582 (Fig. 30G–I), SC 2013.28.583, SC 2013.28.584 (Fig. 30D–F), SC 2013.28.585, SC 2013.28.586, SC 2013.28.587 (Fig. 30J–L), SC 2013.28.588 (8 teeth), SC 2013.28.589 (15 teeth), SC 2013.28.590 (36 teeth), SC 2013.28.591 (15 teeth), SC 2013.28.592 (51 teeth), SC 2013.28.593 (87 teeth).
Description
The isolated teeth are tall, needle-like, and, in profile view, posteriorly curving to varying degrees (Fig. 30A, D, G, J). The crown is conical to somewhat laterally compressed, with the anterior face of the latter morphology being narrower than that of the posterior face (Fig. 30B, E, H). In anterior/posterior view, the crown may be weakly medially curved. Enameloid is not evident on any specimens, but the posterior surface bears numerous closely spaced, parallel vertical ridges extending up to three-quarters of the tooth height. The teeth have a labial carina that extents the height of the tooth. In basal view, the tooth has a circular to elliptical outline, and a circular pulp cavity is deep and framed by a thin wall of dentine (Fig. 30C, F, I, L).
Remarks
The fossil material we examined compares very well to an extant Lophius americanus Cuvier & Valenciennes, 1837 in the MSC collection (MSC 50198), as well as illustrations of Miocene material reported from elsewhere (Purdy et al. 2001: fig. 66c; Schultz 2006: pl. 1 figs 1b, 2b). The lophiid teeth are easily distinguished from the teeth of all other Catahoula Formation teleosts by their tall, needle-like and curved crown, posterior longitudinal ridges, labial carina, and circular basal outline. Additional extant lophiid comparative specimens are needed to further elucidate the taxonomic affinities of these remains.

description: We discuss indirect manifestations of graviton exchange, predicted by large extra dimensions, in fermion-pair production at a high-energy e^+e^- collider. By means of specifically defined asymmetries among integrated angular distributions, the graviton exchange signal can be cleanly distinguished from the effects of either vector-vector contact interactions or heavy scalar exchanges. The role of initial electron and positron beams polarization is also discussed. The method is applied to a quantitative assessment of the sensitivity to the mass cut-off parameter M_H of the KK graviton tower in the ADD scenario, and of the potential identification reach of this mechanism obtainable at the currently planned Linear Collider.

description: The influence of intraphase diffusion on the oxidation of toluene over manganese-based oxide, MnFeOx, under isothermal conditions was investigated. The one-dimensional (1D) heterogeneous model was developed to explain the experimental results. The model can be applied under certain operating conditions, i.e., conditions with negligible resistance to external mass transfer. The article describes the numerical solution of the equations of the proposed model. The relevance of the 1D heterogeneous model compared to the 1D pseudohomogeneous model was also emphasized. Validation of the proposed models was carried out by comparing with experimentally measured results. Both models were found to describe the experimental system studied quite well, with the 1D heterogeneous model providing better insight into the relationship between the rate of chemical reaction and the rate of intraphase diffusion.

Revised equipartition & minimum energy formula for magnetic field strength estimates from radio synchrotron observations
Creators: name: Beck, Rainer
name: Krause, Marita
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The commonly used classical equipartition or minimum-energy estimate of total magnetic fields strengths from radio synchrotron intensities is of limited practical use because it is based on the hardly known ratio K of the total energies of cosmic ray protons and electrons and also has inherent problems. We present a revised formula, using the number density ratio K for which we give estimates. For particle acceleration in strong shocks K is about 40 and increases with decreasing shock strength. Our revised estimate for the field strength gives larger values than the classical estimate for flat radio spectra with spectral indices of about 0.5-0.6, but smaller values for steep spectra and total fields stronger than about 10 muG. In very young supernova remnants, for example, the classical estimate may be too large by up to 10x. On the other hand, if energy losses of cosmic ray electrons are important, K increases with particle energy and the equipartition field may be underestimated significantly. Our revised larger equipartition estimates in galaxy clusters and radio lobes are consistent with independent estimates from Faraday rotation measures, while estimates from the ratio between radio synchrotron and X-ray inverse Compton intensities generally give much weaker fields. This may be explained e.g. by a concentration of the field in filaments. Our revised field strengths may also lead to major revisions of electron lifetimes in jets and radio lobes estimated from the synchrotron break frequency in the radio spectrum.

description: Honeybees forage on diverse flowers which vary in the amount and type of rewards they offer, and bees are challenged with maximizing the resources they gather for their colony. That bees are effective foragers is clear, but how bees solve this type of complex multi-choice task is unknown. Here, we set bees a five-comparison choice task in which five colours differed in their probability of offering reward and punishment. The colours were ranked such that high ranked colours were more likely to offer reward, and the ranking was unambiguous. Bees' choices in unrewarded tests matched their individual experiences of reward and punishment of each colour, indicating bees solved this test not by comparing or ranking colours but by basing their colour choices on their history of reinforcement for each colour. Computational modelling suggests a structure like the honeybee mushroom body with reinforcement-related plasticity at both input and output can be sufficient for this cognitive strategy. We discuss how probability matching enables effective choices to be made without a need to compare any stimuli directly, and the utility and limitations of this simple cognitive strategy for foraging animals.

description: Reconnection heating has been considered as a potential source of the heating of the interstellar medium. In some galaxies, significant polarised radio emission has been found between the spiral arms. This emission has a form of `magnetic arms' that resembles the spiral structure of the galaxy. Reconnection effects could convert some of the energy of the turbulent magnetic field into the thermal energy of the surrounding medium, leaving more ordered magnetic fields, as is observed in the magnetic arms. Sensitive radio and X-ray data for the grand-design spiral galaxy M 83 are used for a detailed analysis of the possible interactions of magnetic fields with hot gas, including a search for signatures of gas heating by magnetic reconnection effects. Magnetic field strengths and energies derived from the radio emission are compared with the parameters of the hot gas calculated from the model fits to sensitive X-ray spectra of the hot gas emission. The available X-ray data allowed us to distinguish two thermal components in the halo of M 83. We found slightly higher average temperatures of the hot gas in the interarm regions, which results in higher energies per particle and is accompanied by a decrease in the energy density of the magnetic fields. The observed differences in the energy budget between the spiral arms and the interarm regions suggest that, similar to the case of another spiral galaxy NGC 6946, we may be observing hints for gas heating by magnetic reconnection effects in the interarm regions. These effects, which act more efficiently on the turbulent component of the magnetic field, are expected to be stronger in the spiral arms. However, with the present data it is only possible to trace them in the interarm regions, where the star formation and the resulting turbulence is low.

Intimate archives : Japanese-Canadian family photography 1939-1949
Creators: name: Kunimoto, Namiko
Publisher: name: University of British Columbia
Year: 2009

description: Anthony Cohen, in The Symbolic Construction of Community, writes: "the symbolic expression of community and its boundaries increases in importance as the actual geo-social boundaries of the community are undermined, blurred or otherwise weakened." As Japanese-Canadians were uprooted from familiar communities throughout British Columbia and overwhelmed with the loss of those closest to them, photography was employed to recentre themselves within a stable, yet somewhat imaginative, network of relations. Looking became an act of imaginative exchange with the subject - conflating the act of seeing with the act of knowing. Photographs became "the most cherished possession" at a time when all else familiar had been lost. It is my contention that domestic photographs and albums produced at this time worked to construct, preserve and contain the visual and imaginative narrative of cohesive family stability and communal belonging, despite divisive political differences, disparate geographical living situations, and elapsed family traditions. While acknowledging that photographs construct and embody a multiplicity of meanings, I am interested in the ways Japanese- Canadian albums were employed during the internment to foster a sense of place while internees existed in a liminal or transitional, marginal space. These representations attempt (and of course sometimes fail) to authenticate a seemingly cohesive biography. Declarations of positive experiences abound throughout the seven family albums I address in this project. Yet there is a double nature to these affirmations. Inscribing "happy times" or "joy" alludes to the silent binary of sadness that is effaced from the images. Representations of state surveillance and poor living conditions are virtually never included but did nonetheless exist. It is not my intention, however, to suggest that photographs are entirely deceptive anymore than they are undeniable truths. Rather, I want to argue that the production, organization and narration of photographs enabled internees to resist being subsumed by fears of persecution and obliteration. The intersection of the photographic image with the viewer constructs a narrative of stability, potentially resulting in a positive experience. Inscribing a positive identity onto images of one's body plays a role in the production of contentment: it is an act which simultaneously elides present troubles and safeguards fond memories for the future, it is a conscious and unconscious maneuver constituting one's personal history. Thus the images not only reinforce a positive experience, but also participate in creating one. It is only when anxieties cannot be contained that representation breaks down. "Intimate Archives" seeks to situate domestic photographs of Japanese-Canadians during the 1942- 1949 exile as intersecting with historical crisis and subjective narrative, tracing the possibilities of meaning for both the depicted subjects and the possessor of the images.

Contrary to the results reported on related systems, we find a transition from the conducting state to an insulating state and a decrease of T$_{C}$ with increasing pressure while the lattice structure remains unchanged. We show that this unusual behavior is driven by a gradual change of the spin state of Co$^{3+}$ ions from magnetic intermediate-spin (t$_{2g}^5$e$_{g}^{1}$; S=1) to a nonmagnetic low-spin (t$_{2g}^6$e$_{g}^{0}$; S=0) state.

The first case study found that climate variability, financial risk, marketing risk, and personal risk were regarded as the major sources of farming risk in the Upper Eyre Peninsula of South Australia. The main management strategies used by farmers included diversifying varieties, minimising tillage, minimising area of risky crops and maximising area of the least-risky crop, having high equity, having farm management deposits and other off-farm investments, and "leaving marketing to experts". The second case study revealed that climate variability was ranked as the most important source of farming risk in southwest Queensland. This was then followed by financial risks, government policy, and marketing risks. The main management strategies used were enterprise diversification (having predominantly cattle and farming cash crops), conserving moisture, using zero till planting, diversified sales (selling only part of the farm's production at any one time), and having off-farm investments. The paper then attempts to reconcile the two case studies by comparing the results with studies from the United States of America, Canada, Netherlands, and New Zealand.

description: Pt nanocontacts, like those formed in mechanically controlled break junctions, are shown to develop spontaneous local magnetic order. Our density functional calculations predict that a robust local magnetic order exists in the atoms presenting low coordination, i. e., those forming the atom-sized neck. In contrast to previous work, we thus find that the electronic transport can be spin-polarized, although the net value of the conductance still agrees with available experimental information. Experimental implications of the formation of this new type of nanomagnet are discussed.

description: The parameter dependence of the various attractive solutions of the three variable nonlinear Lorenz model equations for thermal convection in Rayleigh-Bénard flow is studied. Its bifurcation structure has commonly been investigated as a function of r, the normalized Rayleigh number, at fixed Prandtl number σ. The present work extends the analysis to the entire (r,σ) parameter plane. An onion like periodic pattern is found which is due to the alternating stability of symmetric and non-symmetric periodic orbits. This periodic pattern is explained by considering non-trivial limits of large r and σ. In addition to the limit which was previously analyzed by Sparrow, we identify two more distinct asymptotic regimes in which either σ/r or σ^2/r is constant. In both limits the dynamics is approximately described by Airy functions whence the periodicity in parameter space can be calculated analytically. Furthermore, some observations about sequences of bifurcations and coexistence of attractors, periodic as well as chaotic, are reported.

description: Η επιμόρφωση αποτελεί το σύνολο των δραστηριοτήτων και των διαδικασιών που συνδέονται με τη σύλληψη, το σχεδιασμό και την εφαρμογή ειδικών προγραμμάτων που έχουν ως πρωταρχικό σκοπό τον εμπλουτισμό, την αναβάθμιση και την περαιτέρω ανάπτυξη των ακαδημαϊκών, θεωρητικών, και πρακτικών επαγγελματικών και προσωπικών ενδιαφερόντων, ικανοτήτων, γνώσεων και δεξιοτήτων των εκπαιδευτικών κατά την διάρκεια της θητείας τους. Αν και οι εκπαιδευτικοί κατά τη διάρκεια των προπτυχιακών σπουδών τους έχουν αποκτήσει τις θεμελιώδεις γνώσεις με τη βοήθεια των οποίων θα αντιμετωπίσουν τις προκλήσεις μέσα στην τάξη, είναι χρήσιμο αν όχι απαραίτητο να παρακολουθούν επιμορφωτικά προγράμματα έτσι ώστε να κάνουν πιο αποτελεσματικό το έργο της διδασκαλίας και να μπορούν να εξελιχθούν επαγγελματικά. Οι εκπαιδευτικές προκλήσεις που αντιμετωπίζουν οι εκπαιδευτικοί μπορούν να περιγραφούν από τις κοινωνικοπολιτισμικές συνθήκες που επικρατούν στην Ελλάδα. Πιο συγκεκριμένα: 1. τα τελευταία χρόνια έχει αυξηθεί κατά πολύ ο αριθμός των μαθητών που έχουν διαγνωστεί με κάποια μορφή μαθησιακής δυσκολίας ή με συναισθηματικές διαταραχές 2. η Ελλάδα τα τελευταία χρόνια έχει δεχθεί μεγάλο αριθμό μεταναστών και προσφύγων με συνέπεια οι τάξεις να έχουν γίνει πολυπολιτισμικές 2 3. οι οικονομικές συνθήκες, οι κρίσεις μέσα στην οικογένεια και πολλοί άλλοι παράγοντες έχουν αυξήσει τον αριθμό των παιδιών που παρουσιάζουν παραβατικές συμπεριφορές Πολλές φορές λοιπόν, η βασική εκπαίδευση που έχουν λάβει εκπαιδευτικοί από το πανεπιστήμιο δεν επαρκεί προκειμένου να αντιμετωπίσουν τις καταστάσεις που προαναφέραμε. Έτσι είναι επιτακτική η ανάγκη για περαιτέρω επιμόρφωση. Η αυτοαξιολόγηση είναι μία διαδικασία κατά την οποία ο εργαζόμενος κρίνει την ίδια του την εργασία. Όσον αφορά το εκπαιδευτικό σύστημα οι τομείς της αυτοαξιολόγησης είναι η αυτοαξιολόγηση της σχολικής μονάδας, η αυτοαξιολόγηση του μαθητή, η αυτοαξιολόγηση του εκπαιδευτικού και η αυτοαξιολόγηση της ομάδας του διδακτικού προσωπικού. Κατά τη διαδικασία της αυτοαξιολόγησης ο εκπαιδευτικός διερευνά τα συναισθήματα του, τον εαυτό του, παρατηρεί και αξιολογεί τις ενέργειές του, τις επιδόσεις του, την εκπαιδευτική του επάρκεια και επαναπροσδιορίζει τους στόχους του. Η αυτοαξιολόγηση των εκπαιδευτικών είναι μία διαδικασία που στοχεύει στη βελτίωσή τους, επικεντρώνεται στους εκπαιδευτικούς πραγματοποιείται από τους εκπαιδευτικούς, είναι συνεχής και δεν σταματά να βελτιώνεται, δεν έχει συγκεκριμένο τρόπο που πραγματοποιείται, αποτελεί στάδιο λήψης αποφάσεων από τους εκπαιδευτικούς για το έργο και τη συμπεριφορά τους, τους δίνει τη δυνατότητα να δουν τα επιτεύγματά τους και τέλος αποτελεί μέθοδο αυτογνωσίας και αυτό αποδοχής.

description: In the past few years collisionally pumped extreme ultraviolet (XUV) lasers utilizing a capillary discharge were demonstrated. An intense current pulse is applied to a gas filled capillary, inducing magnetic collapse (Z-pinch) and formation of a highly ionized plasma column. Usually, a small current pulse (pre-pulse) is applied to the gas in order to pre-ionize it prior to the onset of the main current pulse. In this paper we investigate the effects of the pre-pulse on a capillary discharge Ne-like Ar XUV laser (46.9nm). The importance of the pre-pulse in achieving suitable initial conditions of the gas column and preventing instabilities during the collapse is demonstrated. Furthermore, measurements of the amplified spontaneous emission (ASE) properties (intensity, duration) in different pre-pulse currents revealed unexpected sensitivity. Increasing the pre-pulse current by a factor of two caused the ASE intensity to decrease by an order of magnitude - and to nearly disappear. This effect is accompanied by a slight increase in the lasing duration. We attribute this effect to axial flow in the gas during the pre-pulse.

description: The radio mini halos (MH) observed in relaxed clusters probe the presence of relativistic particles on scales of hundreds of kpc, beyond the scales directly influenced by the central AGN, but the nature of the mechanism that produces the relativistic electrons is still debated. In this work we explore the connection between thermal and non-thermal components of the ICM in a sample of MH and we study its implications for hadronic models for the origin of the relativistic electrons. We studied the thermal and non-thermal connection by carrying out a point-to-point comparison of the radio and the X-ray surface brightness. We extended the method generally applied to giant radio halos by considering the effects of a grid randomly generated through a Monte Carlo chain. Contrary to what is generally observed for giant radio halos, we find that the mini-halos in our sample have super-linear scaling between radio and X-rays, which suggests a peaked distribution of relativistic electrons and magnetic field. We used the radio and X-ray correlation to constrain the physical parameters of a hadronic model and we compared the model predictions with current observations. Specifically, we focus on a model where cosmic rays are injected by the central AGN and they generate secondaries in the ICM, and we assume that the role of turbulent re-acceleration is negligible. This model allows us to constrain the AGN cosmic ray luminosity in the range $\sim10^{44-46}$ erg s$^{-1}$ and the central magnetic field in the range 10-40 $μ$G. The resulting $γ$-ray fluxes calculated assuming these model parameters do not violate the upper limits on $γ$-ray diffuse emission set by the Fermi-LAT telescope. Further studies are now required to explore the consistency of these large magnetic fields with Faraday rotation studies and to study the interplay between the secondary electrons and the ICM turbulence.

description: There are several examples of bipartite entangled states of continuous variables for which the existing criteria for entanglement using the inequalities involving the second order moments are insufficient. We derive new inequalities involving higher order correlation, for testing entanglement in non-Gaussian states. In this context we study an example of a non-Gaussian state, which is a bipartite entangled state of the form $ψ(x_{\rm a},x_{\rm b})\propto (αx_{\rm a}+βx_{\rm b})e^{-(x_{\rm a}^2+x_{\rm b}^2)/2}$. Our results open up an avenue to search for new inequalities to test entanglement in non-Gaussian states.
