Phased-MIMO Radar: A Tradeoff Between Phased-Array and MIMO Radars
Creators: name: Hassanien, Aboulnasr

Publisher: name: arXiv

Subjects: subject: Information Theory (cs.IT)

description: We propose a new technique for multiple-input multiple-output (MIMO) radar with colocated antennas which we call phased-MIMO radar. The new technique enjoys the advantages of MIMO radar without sacrificing the main advantage of phased-array radar which is the coherent processing gain at the transmitting side. The essence of the proposed technique is to partition the transmitting array into a number of subarrays that are allowed to overlap. Then, each subarray is used to coherently transmit a waveform which is orthogonal to the waveforms transmitted by other subarrays. Coherent processing gain can be achieved by designing a weight vector for each subarray to form a beam towards a certain direction in space. Moreover, the subarrays are combined jointly to form a MIMO radar resulting in higher resolution capabilities. The substantial improvements offered by the proposed phased-MIMO radar technique as compared to previous techniques are demonstrated analytically and by simulations through analysis of the corresponding beampatterns and achievable output signal-to-noise-plus-interference ratios. Both analytical and simulation results validate the effectiveness of the proposed phased-MIMO radar.

The effect of methyl testosterone on secondary sex characters and reproductive behaviour of gonadectomized sticklebacks (Gasterosteus aculeatus L.)
Creators: name: Wai, Evelyn
Publisher: name: University of British Columbia
Year: 2011

description: Treatment of gonadectomized adult male and female sticklebacks as well as normal juvenile, with methyl testosterone, either by immersion in a hormone solution or by implanting hormone pellets, induces the kidney cells to develop into granular and mucous cells, accompanied by an increase in cell height. Increase in cell height, up to a limit, is a function of the length of hormone treatment. Prespawning aggressiveness and territoriality is induced in gonadectomized fish of both sexes by maintaining them under long photoperiod for four to five weeks. Short photoperiod has no effect. Administration of methyl testosterone to the already aggressive fish showed no definite effect on this behaviour. The combined effect of long photoperiod and methyl testosterone treatment induces the nest-building behaviour in gonadectomized males and females with a much higher percentage in the former than in the latter. The component elements of the nest-building movement in the treated gonadectomized male is similar qualitatively and quantitatively to that of the normal reproducing male. Treated gonadectomized females show deviations from the normal male in their nest-building movements. Sexual behaviour is the same in castrates treated with methyl testosterone as in the normal reproducing male, but completely absent in the similarly treated gonadectomized females.

description: We report the formation of stable nanoparticle-polymer clusters obtained by electrostatic complexation. The nanoparticles placed under scrutiny are nanoceria (CeO2) coated by short poly(acrylic acid) moieties, whereas the polymers are cationic-neutral block copolymers. The cluster formation was monitored using different formulation pathways, including direct mixing, dialysis, dilution and quenching. In the first process, the hybrids were obtained by mixing stock solutions of polymers and nanoparticles. Dialysis and dilution were based on controlled desalting kinetics according to methods developed in molecular biology. The fourth process consisted in a rapid dilution of the salted dispersions and as such it was regarded as a quench of the cluster kinetics. We have found that one key parameter that controls the kinetics of formation of electrostatic clusters is the rate dIS/dt at which the salt is removed from the solution, where IS denotes the ionic strength. With decreasing IS, the electrostatically screened polymers and nanoparticles system undergo an abrupt transition between an unassociated and a clustered state. By tuning the desalting kinetics, the size of the clusters was varied from 100 nm to over 1 micrometer. At low ionic strength, the clusters were found to be kinetically frozen. It is proposed that the onset of aggregation is driven by the desorption-adsorption transition of the polymers onto the surfaces of the particles.

description: We present a thermal inflation model that incorporates the Affleck-Dine leptogenesis in heavy gravitino/moduli scenario, which solves the moduli-induced gravitino problem while producing a correct amount of baryon asymmetry and relic dark matter density. The model involves two singlet flat directions stabilized by radiative corrections associated with supersymmetry breaking, one direction that generates the Higgs μand B parameters, and the other direction that generates the scale of spontaneous lepton number violation. The dark matter is provided by the lightest flatino which might be identified as the axino if the model is assumed to have a U(1)_{PQ} symmetry to solve the strong CP problem. We derive the conditions for the model to satisfy various cosmological constraints coming from the Big-Bang nucleosynthesis and the dark matter abundance.

description: In the present study, a sample pretreatment based on the combination of vortex assisted liquid–liquid extraction and dispersive liquid–liquid microextraction has been proposed for the isolation and preconcentration of three acidic herbicides including fenoxaprop, fluazifop, and haloxyfop from edible oil samples. For this purpose, firstly, the analytes were extracted into sodium hydroxide solution (by deprotonating the analytes) which was used as a dispersive solvent in the following microextraction procedure. The obtained aqueous phase was mixed with acetic acid as a pH adjustment agent and co–disperser solvent. After the addition of dichloromethane (extraction solvent) to the above solution, it was quickly dispersed into deionised water. The validation parameters indicated that the limits of detection and quantification of the proposed method were in the ranges of 0.3–1.8 and 1.0–6.0 ng mL–1, respectively. Relative standard deviations of the method were obtained in the range of 4.8–6.2% and 5.2–9.1% for intra – (n = 6) and inter–day (n = 5) precisions, respectively. High extraction recoveries and enrichment factors ranged from 74 to 91%, and 185 to 227 were the other advantages of the method. These merits showed that the proposed method is efficient and sensitive for the determination of the studied analytes in the edible oil samples.

description: Der "Babylonische Fürstenspiegel", international auch bekannt als "Advice to a Prince", beinhaltet Richtlinien für königliches Verhalten und beschreibt Konsequenzen, sollten diese Richtliniennicht beachtet werden. Aufgrund dieser Elemente ist dem Inhalt dieses Texts viel Aufmerksamkeit in der Forschung gewidment worden, der literarischen Qualität des Textes gedoch ungleich weniger. In diesem Artikel werden Mittel zur Strukturierung des Textes untersucht und in Hinblick auf ihr Potenzial für ein tieferes Verständnis des Textes ausgewertet. Zunächst wird die literarische Natur des Textes behandelt, ebenso seine Verbindungen zu divinatorischen Texten, insbesondere zur terrestrischen Omenserie Šumma aāāālu. Darauf folgen zwei Fallstudien zu strukturierenden Elementen des Tets. In der ersten Fallstudie wird gezeigt, dass strukturierende Elemente für den Textzusammenhalt genutzt werden, um den Text als ein literarisches Ganzes zu präsentieren, was Auswirkungen auf die Interpretation und die Bedeutung des Textes hat. Die zweite Fallstudie behandelt die Mikrostruktur des Textes, insbesondere in Bezug auf die Gesamtstruktur des Babylonischen Fürstenspiegels. Dabei wird ausgeführt, dass Mikrostruktur genutzt werden kann um Elemente des Texts zu betonen, wodurch eine weitere Bedeutungsebene des Texts erschlossen werden kann.
description: The Babylonian Fürstenspiegel, also known as the Advice to a Prince, has attracted scholarly interest because it provides guidelines for royal behaviour and describes the consequences if these guidelines are not followed. While the content of this text has been amply discussed, the literary quality of the Fürstenspiegel has received decidedly less attention. In this paper, I examine some structural devices in the Babylonian Fürstenspiegel and analyse their potential for enriching our understanding of the text. I first discuss the literary nature of this text and its relationship with divinatory texts, particularly the terrestrial omen series Šumma aāāālu. I then analyse some structural devices employed in the text through two case studies. In the first case study, I argue that structural devices are used to make the text cohere as a literary whole, with implications for its wider meaning. In the second case study, I argue that the text's micro-structure, especially in relation to the text’s overall structure, can be used to add emphasis, providing another layer of meaning to this text.

Il potere del fischio. Un percorso tra usi e riusi cinematografici
Creators: name: Cosci, Marco
Publisher: name: Musica Docta
Year: 2023

description: Fin dall’avvento del cinema sonoro, il fischio umano è stato impiegato in una vasta gamma di situazioni, che vanno dalla spensieratezza all’ambito del perturbante. Nonostante la loro apparente semplicità, le melodie fischiate possono acquisire una centralità nella drammaturgia sonora di un film, grazie anche a quelle proprietà timbriche che collocano il fischio in uno spazio fluido tra il dominio vocale e quello strumentale. Il percorso didattico è rivolto a studenti di Teoria, analisi e composizione e Storia della musica dei licei musicali, nonché a quelli di analoghe discipline musicali insegnate nei conservatori e nei corsi universitari. A partire dall’analisi di alcune sequenze cinematografiche esemplificative in cui sono presenti brani di musica fischiati, si intende fornire strumenti analitici utili per comprenderne il ruolo fondamentale di tali musiche nella comunicazione multimediale. A tal fine, sono illustrati alcuni concetti chiave utili a inquadrare le strategie di costruzione audiovisive, fornendo metodologie di indagine e competenze applicabili anche ad altri elementi della colonna sonora. Infine, si focalizza l’attenzione sui processi di ri-semantizzazione attivati dalla citazione di musiche preesistenti, anche alla luce dei rimandi intertestuali e intermediali.

description: We calculate the inclusive and diffractive photoproduction of heavy quarks in proton-proton collisions at Tevatron and LHC energies, where the photon reaches energies larger than those ones accessible at DESY-HERA. The integrated cross section and the rapidity distributions for charm and bottom production are computed within the color dipole picture employing three phenomenological saturation models based on the Color Glass Condensate formalism. Our results demonstrate that the experimental analyzes of these reactions is feasible and that the cross sections are sensitive to the underlying parton dynamics.

description: This study reported the determination of humic acid (HA) and sodium alginate (Na-Alg) at glassy carbon electrode (GCE) modified with iron oxide (Fe2O3) and copper oxide (CuO) nanoparticles (NPs), respectively. The synthesised NPs were characterised using spectroscopic and microscopic techniques. Successful modification of the electrode with NPs was confirmed with 1 mM Ferri/Ferro ([Fe(CN)6]3−/4−) redox probe using cyclic voltammetry and electrochemical impedance spectroscopy (EIS). Results indicated that GCE-Fe2O3 and GCE-CuO have higher current responses with lower charge transfer resistance (Rct) compared with the bare GCE. Electrocatalytic oxidation of HA and Na-Alg at the modified electrode showed a current drop due to adsorption of the analyte or electrode fouling effect. GCE-CuO showed better resistance to the analyte fouling effect with 17.7% and 31.1% current drops after second scan in HA and Na-Alg, respectively. The limit of detection values were 5.42 μM (HA), 5.06 μM (Na-Alg) at GCE-Fe2O3 electrode and 4.88 μM (HA), 3.82 μM (Na-Alg) at GCE-CuO electrode using LSV technique. The adsorption equilibrium constant β at the electrodes ranged from 3.03 to 60.50 × 104 M−1, while free energy due to adsorption ΔGo ranged from −25.57 to −32.99 kJmol−1. The developed sensors can be used for detection and monitoring of HA and sodium alginate in treated and untreated water samples.

description: I due volumi qui recensiti sono rivolti principalmente – ma non solo – agli studenti di Scienze della Formazione primaria; essi rispondono al bisogno di formazione che in chi frequenta questi corsi (e nei docenti di questi ordini di scuola) risulta spesso assi carente. Il volume di Asinari si presenta come una sorta di compendio che tocca un po’ tutti gli àmbiti riguardanti la musica, e che potrebbe fornire un utile supporto a coloro i quali, sprovvisti di una formazione specifica, dovranno studiare le discipline musicali nel loro percorso universitario. La miscellanea di Mari, realizzata con musicisti e docenti che la affiancano nei suoi corsi, è maggiormente incentrata sull’aspetto didattico: ai contributi di natura pedagogica e metodologica, corredati da un’analisi del quadro normativo, si affiancano interventi di carattere pratico, contenenti suggerimenti operativi e proposte didattiche concrete. Al di là delle diverse impostazioni, i contributi dei due volumi sono accomunati dall’elevato valore formativo attribuito alla musica: pur percorrendo strade diverse, gli autori cercano di condurre l’educazione musicale sulla strada dell’emancipazione dal ruolo di mero intrattenimento che l’accompagna da lungo tempo.

description: The dynamics of the acceleration of ultrathin foil targets by the radiation pressure of superintense, circularly polarized laser pulses is investigated by analytical modeling and particle-in-cell simulations. By addressing self-induced transparency and charge separation effects, it is shown that for "optimal" values of the foil thickness only a thin layer at the rear side is accelerated by radiation pressure. The simple "Light Sail" model gives a good estimate of the energy per nucleon, but overestimates the conversion efficiency of laser energy into monoenergetic ions.

Energy Dependance of Azimuthal Correlations (and more) in Nucleus-Nucleus Collisions at the CERN SPS

Year: 2009

description: Analysing two-particle azimuthal and pseudorapidity-azimuth correlations of high-pT hadrons, experiments at the RHIC have obtained results - "the double hump", "the ridge" etc. - which provide interesting information about properties of the hot, dense medium produced in central high-energy heavy-ion collisions as well as of its interaction with products of hard scattering. However, not all of the observed effects have been fully explained by theory or models yet; such explanations are hampered in part by the lack of good reference from lower collision energies. In an attempt to further our understanding of angular dihadron correlations NA49 has, as one of the first experiments at the SPS, performed a number of scans of these correlations in Pb+Pb, Si+Si and p+p collisions at sqrt(sNN) = 17.3 GeV, as well as central Pb+Pb collisions at sqrt(sNN) = 12.3, 8.8, 7.6 and 6.3 GeV. Results of these scans have been compared to UrQMD simulations. Our experimental results from two-particle azimuthal correlations show a flattened away-side peak in central Pb+Pb (Au+Au) collisions, only weakly depends on collision energy over the whole investigated energy range - suggesting this effect originates from sources other than jet-medium interactions. This hypothesis is reinforced by good agreement with UrQMD regardless of whether jet production was enabled in the model or not. On the other hand, the amplitude of the near-side peak in central Pb+Pb (Au+Au) collisions drops visibly with decreasing collision energy, flattening out around sqrt(sNN) = 8.8 GeV and turning into a depletion below that energy - possibly an effect related to the onset of deconfinement. Finally, hints of the ridge structure can be observed in pseudorapidity-azimuth correlation functions from central Pb+Pb collisions at sqrt(sNN) = 17.3 GeV.

description: We present local numerical models of accretion disk turbulence driven by the magnetorotational instability with varying shear rate. The resulting turbulent stresses are compared with predictions of a closure model in which triple correlations are modelled in terms of quadratic correlations. This local model uses five nondimensional parameters to describe the properties of the flow. We attempt to determine these closure parameters for our simulations and find that the model does produce qualitatively correct behaviour. In addition, we present results concerning the shear rate dependency of the magnetic to kinetic energy ratio. We find both the turbulent stress ratio and the total stress to be strongly dependent on the shear rate.

The model includes self-consistently the effects of particle screening, electron degeneracy and correlations between electrons and ions. We successfully validate the model over a wide range of plasma coupling against molecular-dynamics simulations of classical plasma of like-charged electrons and ions. We present calculations of the relaxation rates in dense hydrogen and show that, while electron-ion correlation effects are indispensable in classical, like-charged plasmas at any density and temperature, quantum diffraction effects prevail over e-i correlation effects in dense hydrogen plasmas.

Trρ_A^n for any integer n is calculated as the four-point function of a particular type of twist fields and the final result is expressed in a compact form in terms of the Riemann-Siegel theta functions. In the decompactification limit we provide the analytic continuation valid for all model parameters and from this we extract the entanglement entropy. These predictions are checked against existing numerical data.

Stochastic Measures and Modular Evolution in Non-equilibrium Thermodynamics

description: We present an application of the theory of stochastic processes to model and categorize non-equilibrium physical phenomena. The concepts of uniformly continuous probability measures and modular evolution lead to a systematic hierarchical structure for (physical) correlation functions and non-equilibrium thermodynamical potentials. It is proposed that macroscopic evolution equations (such as dynamic correlation functions) may be obtained from a non-equilibrium thermodynamical description, by using the fact that extended thermodynamical potentials belong to a certain class of statistical systems whose probability distribution functions are defined by a stationary measure; although a measure which is, in general, different from the equilibrium Gibbs measure. These probability measures obey a certain hierarchy on its stochastic evolution towards the most probable (stationary) measure. This in turns defines a convergence sequence. We propose a formalism which considers the mesoscopic stage (typical of non-local dissipative processes such as the ones described by extended irreversible thermodynamics) as being governed by stochastic dynamics due to the effect of non-equilibrium fluctuations. Some applications of the formalism are described.

description: Objectives: Though the pathophysiology underlying schizophrenia (SCZ) and bipolar disorder (BD) is not fully understood, immune function may be dysregulated, with microglia, the brain’s resident immune cells, implicated in this process. Signaling between the neuronal chemokine fractalkine (CX3CL1) and its microglial receptor CX3CR1 facilitates neuron-microglia interactions, influencing microglial activation and synaptic function. As such, alterations in fractalkine signaling may contribute to immune and synaptic alterations observed in SCZ and BD. Methods: Protein and mRNA expression of fractalkine, CX3CR1, and a disintegrin and metalloproteinase 10 (ADAM10), a sheddase that cleaves fractalkine, were quantified in postmortem frontal cortex from individuals with SCZ (n = 35), BD (n = 34), and matched controls (n = 35) using immunoblotting and droplet digital PCR. In addition, the relationship between fractalkine pathway members and levels of the pre-synaptic protein SNAP-25 was examined. Results: Fractalkine protein levels were significantly lower in SCZ relative to controls. Expression of members of the fractalkine signaling pathway was unchanged in BD. CX3CR1 protein levels were significantly correlated with SNAP-25 levels. Conclusions: The observed deficit in fractalkine protein levels in SCZ is consistent with impaired neuron-microglia crosstalk in this disorder. Furthermore, our data is suggestive of an aberrant association between microglial function and synaptic density in SCZ.

description: The conceptual modelling built from text is rarely an ontology. As a matter of fact, such a conceptualization is corpus-dependent and does not offer the main properties we expect from ontology. Furthermore, ontology extracted from text in general does not match ontology defined by expert using a formal language. It is not surprising since ontology is an extra-linguistic conceptualization whereas knowledge extracted from text is the concern of textual linguistics. Incompleteness of text and using rhetorical figures, like ellipsis, modify the perception of the conceptualization we may have. Ontological knowledge, which is necessary for text understanding, is not in general embedded into documents.

Communication in a Vancouver social agency
Creators: name: Chave, Dorothy Mary
Publisher: name: University of British Columbia
Year: 2011

description: This report is a study of communication between a range of groups that make up the "society’ of Alexandra Neighbourhood House, a member agency of the Greater Vancouver Community Chest and Council. The purpose of the study is to: 1) identify certain parts of this society as sub-cultural groups; 2) to analyse selected aspects of interaction as they characteristically take place within each group; 3) to compare these aspects of communication within the Neighbourhood House organization with interaction in other unrelated bureaucratic settings. The purpose has not included any attempt to evaluate the function of the agency in the context of the social welfare community. The main method of analysis in this report has been a comparative one in which eleven aspects of interaction have been drawn from a study of communication done by Keesing on elite groups in Samoa. For further comparative scope examples of interaction in community development projects in India have been used. Data for the research on the Neighbourhood House have come from the writer's experience as a caseworker at Alexandra Neighbourhood House during the years i960 and 1961. In that time interviews were held with representative persons from the sub-cultural groups. The findings include uncovering certain constellations of values that appear to be present in certain sub-groups in the society. The concept of 'value' has not been stringently worked out but rather what are called values in this report are the writer's opinion of the important elements, stated or implied, in the respondents' statements. No attempt has been made to assess the relative importance of the values within the groups concerned. Certain similarities and differences in the aspects of interaction in groups in the House and in the: non-Western societies compared have been brought out. The effect of imposed or 'foreign' elements in a society such as the introduction of persons who hold authority outside the traditional lines has also been compared. It was not possible in an initial study such as this to reach a full synthesis between the establishment of the groups as sub-cultures, the identification of characteristic modes of intra-group interaction and finally the type of inter group communication within the society. However, it is believed that the report does point to some sources of Inter group difficulty and misunderstanding.
The orientations of galaxy groups and formation of the Local Supercluster

description: We analysed the orientation of galaxy groups in the Local Supercluster (LSC). It is strongly correlated with the distribution of neighbouring groups in the scale till about 20 Mpc. The group major axis is in alignment with both the line joining the two brightest galaxies and the direction toward the centre of the LSC, i.e. Virgo cluster. These correlations suggest that two brightest galaxies were formed in filaments of matter directed towards the protosupercluster centre. Afterwards, the hierarchical clustering leads to aggregation of galaxies around these two galaxies. The groups are formed on the same or similarly oriented filaments. This picture is in agreement with the predictions of numerical simulations.

Musicologia e critica musicale: specificità, interazioni, implicazioni pedagogico-didattiche
Creators: name: Misuraca, Pietro
Publisher: name: Musica Docta
Year: 2023

description: Quelli del musicologo e del critico musicale sono due profili professionali distinti e ben caratterizzati, ma possono essere complementari e se ne può auspicare un possibile incontro. Il presente contributo, tirando le fila di un lungo dibattito, si sofferma sulla specificità delle due professioni, sul bagaglio di conoscenze a entrambe necessario e sulle loro funzioni differenziate ma all’occorrenza interscambiabili. Una fruttuosa circolarità può infatti innescarsi nel momento in cui entrambe le attività si pongano l’obiettivo primario di «manifestare attraverso la parola la specifica esperienza musicale e le specifiche qualità dell’opera» (Adorno), affrontando la sfida della transcodificazione verbale e fornendo al lettore chiavi di interpretazione e di accesso. La formazione dei professionisti della musica e il loro ruolo nella società italiana sono temi che si legano inevitabilmente alle questioni spinose dell’insegnamento musicale e della posizione marginale che esso occupa nel nostro ordinamento scolastico, con pesanti ricadute sul lavoro quotidiano di coloro che operano professionalmente nell’ambito musicale. Nonostante i problemi pratici che condizionano la produzione giornalistica, il discorso critico non dovrebbe essere mera cronaca, ma un anello della catena ermeneutica. Ogni critica seria sulla performance è anche un’esegesi dell’opera eseguita. La competenza musicologica consentirebbe al critico di riappropriarsi dell’autorevolezza negli spazi liberi e privi di filtri del web e di mantenere una propria funzione all’interno di uno scenario culturale che negli ultimi anni è profondamente cambiato. Allo stesso modo, il giudizio critico-estetico dovrebbe rientrare fra le componenti di ogni esercizio musicologico che ambisca a qualche ampiezza di respiro culturale e che sappia rendersi capace di creare un ponte di collegamento con una platea più vasta. Questione non meno importante è il confronto con il pensiero e la creatività contemporanea: l’attuale assenza di dibattito critico sulla musica nuova è infatti un problema che investe tanto il mandato etico-politico del critico musicale quanto i rapporti tra musicologia e società civile.

description: Il presente contributo propone alcune riflessioni sulle caratteristiche peculiari e sulle maggiori criticità di Wikipedia, con particolare riguardo verso la prospettiva legata allo studio della storia della musica. Come caso specifico viene presa in esame la voce dedicata ad Alessandro Scarlatti. A partire dall’analisi delle considerazioni scritte nella pagina di “discussione” e delle modifiche effettuate dagli utenti, si ripercorrono le tappe più significative dell’evoluzione di tale voce, per poi avanzare delle considerazioni di carattere generale derivanti dal confronto con il corrispettivo lemma di un progetto “tradizionale” di comprovata autorevolezza: il Dizionario biografico degli Italiani.

description: We show how to incorporate chiral symmetry breaking in the soft-wall version of the AdS/QCD model by using a modified dilaton profile and a quartic term in the bulk scalar potential. This allows one to separate the dependence on spontaneous and explicit chiral symmetry breaking. Moreover our 5D model automatically incorporates linear trajectories and non chiral-symmetry restoration for highly excited radial states. We compare our resulting mass spectra in the scalar, vector and axial-vector sectors with the respective QCD resonances and find reasonable agreement using the known values for the pion mass and decay constant.

description: L’archivio del centro di ricerca, produzione e didattica musicale Tempo Reale’ fondato da Luciano Berio nel 1987, costituisce un patrimonio di grande importanza per la storia recente della musica elettronica. Il contributo dà conto delle iniziative portate a termine per la sua valorizzazione, così come di alcuni progetti in corso di realizzazione: in particolare, sono esposti i metodi e le prospettive adottati con l’obiettivo di divulgare la conoscenza del patrimonio, ampliare l’accesso e coinvolgere i potenziali stakeholder dell’archivio. A partire da questa esperienza circoscritta, facendo ricorso al concetto di ‘attivazione’ del patrimonio, sono delineati alcuni orizzonti teorici che chiamano in causa la possibile costruzione e trasmissione partecipata di una ‘cultura della musica elettronica’.

description: We propose a new strategy for detecting the CP-violating phases and the effective mass of muon Majorana neutrinos by measuring observables associated with neutrino-antineutrino oscillations in $π^{\pm}$ decays. Within the generic framework of quantum field theory, we compute the non-factorizable probability for producing a pair of same-charged muons in $π^{\pm}$ decays as a distinctive signature of $ν_μ-\bar{ν_μ}$ oscillations. We show that an intense neutrino beam through a long baseline experiment is favored for probing the Majorana phases. Using the neutrino-antineutrino oscillation probability reported by MINOS collaboration, a new stringent bound on the effective muon-neutrino mass is derived.
