description: Η παρούσα διατριβή εφαρμόζει τις βασικές αρχές της αφηγηματολογίας ως σύγχρονης θεωρίας της αφήγησης στις Φοίνισσες του Ευριπίδη στοχεύοντας σε μια βαθύτερη κατανόηση των εσωτερικών αφηγηματικών δομών του έργου. Στα δύο πρώτα κεφάλαια εξετάζεται η αφήγηση πριν και μετά την πρώτη μάχη Αργείων και Θηβαίων. Η πρώτη αναμέτρηση Αργείων και Θηβαίων αποτελεί τον δραματικό πυρήνα πριν από τον οποίο τα γεγονότα ιδιαίτερου δραματικού βάρους τυγχάνουν σκηνικής αφήγησης και μετά τον οποίο η δράση μετατίθεται εξωσκηνικά. Στο πρώτο κεφάλαιο («Ξαναγράφοντας το παρελθόν, οργανώνοντας το μέλλον: σκηνική αφήγηση και εξωσκηνικοί υπαινιγμοί») αποκωδικοποιούνται οι αφηγηματικοί μηχανισμοί που δομούν το πρώτο μέρος του έργου και εξάγονται συμπεράσματα σχετικά με το είδος της αφήγησης που χρησιμοποιείται για τα εξωσκηνικά γεγονότα και τον τρόπο με τον οποίο η τριπλή χρονική διάσταση ενσωματώνεται στην παροντική δραματική αφήγηση. Στο δεύτερο κεφάλαιο («Ανατρέποντας τις προσδοκίες: εξωσκηνική αφήγηση, αγγελικές ρήσεις και το ανοιχτό τέλος του έργου») εξετάζεται το δεύτερο μέρος της τραγωδίας, σημαντικότερο χαρακτηριστικό του οποίου είναι οι ανατροπές των αφηγηματικών προσδοκιών. Στο τρίτο κεφάλαιο («Διακειμενικότητα») μελετάται η διακειμενικότητα και επιχειρείται η αφηγηματολογική τοποθέτηση των Φοινισσών σε ένα ευρύτερο διακειμενικό πλαίσιο. Τέλος, στο τέταρτο κεφάλαιο («Χώρος») εξετάζεται η έννοια του χώρου στο δράμα και προτείνεται μια αφηγηματική «χαρτογράφηση» των Φοινισσών
description: The aim of this doctoral dissertation is to apply the basic principles of narratology as a modern theoretical tool to Euripides' Phoenissae. The first two chapters deal with the types of narration used before and after the first battle between the Argives and the Thebans. The battle works as a narrative nucleus, placed in the middle of the play, before and after which the dramatically important events are narrated on- and off-stage respectively. In the first chapter ("Rewriting the past, organizing the future: onstage narration and offstage allusions") I explore the narrative mechanisms that construct the first part of the play, interpreting the types of narration used for the description of the offstage events and the ways the tri-dimensional concept of time is infused into a present-oriented narrative. In chapter two ("Overturning the narrative expectations: offstage narrative, messenger speeches and the play's open end") I study the narrative of the second part of the play, whose most important characteristic are the narrative twists that overturn former narrative expectations. In the third chapter ("Intertextuality") I discuss the play's intertextual allusions, positioning it within a wider intertextual nexus. Finally, in chapter four ("Space") I examine the concept of dramatic space and I seek to draw the narrative "map" upon which the Phoenissae expands

description: We measure the low bias conductance of a series of substituted benzene diamine molecules while breaking a gold point contact in a solution of the molecules. Transport through these substituted benzenes is by means of nonresonant tunneling or superexchange, with the molecular junction conductance depending on the alignment of the metal Fermi level to the closest molecular level. Electron-donating substituents, which drive the occupied molecular orbitals up, increase the junction conductance, while electron-withdrawing substituents have the opposite effect. Thus for the measured series, conductance varies inversely with the calculated ionization potential of the molecules. These results reveal that the occupied states are closest to the gold Fermi energy, indicating that the tunneling transport through these molecules is analogous to hole tunneling through an insulating film.

description: Our aim is to study the polarization of thermal dust emission to see if the alignment of grain by radiative torques could explain the observed relation between the degree of polarization and the intensity in dense cores. Predictions are made for polarimetry observations with the Planck satellite. Our results are based on model clouds derived from MHD simulations of magnetized turbulent flows, while the continuum radiative transfer problem is solved with Monte Carlo methods in order to estimate the three-dimensional distribution of dust emission and the radiation field strength affecting the grain alignment. The influence of grain alignment efficiency is examined in the calculated polarization maps. We are able to reproduce the P/I-relation with the grain alignment by radiative torques. The decrease in intrinsic polarization and total emission means that sub-mm polarimetry carries only little information about the magnetic fields in dense cores with high visual extinction. The interpretation of the observations will be further complicated by the unknown magnetic field geometry and the fact that what is observed as individual cores may, in fact, be a superposition of several density enhancements. According to our calculations, Planck will be able to map dust polarization reliably when A_V > 2 mag at spatial resolution of 15'.

description: Elements with low First Ionization Potential (FIP) are known to be three to four times more abundant in active region loops of the solar corona than in the photosphere. There have been observations suggesting that this observed "FIP bias" may be different in other parts of the solar corona and such observations are thus important in understanding the underlying mechanism. The Solar X-ray Monitor (XSM) on board the Chandrayaan-2 mission carried out spectroscopic observations of the Sun in soft X-rays during the 2019-20 solar minimum, considered to be the quietest solar minimum of the past century. These observations provided a unique opportunity to study soft X-ray spectra of the quiescent solar corona in the absence of any active regions. By modelling high resolution broadband X-ray spectra from XSM, we estimate the temperature and emission measure during periods of possibly the lowest solar X-ray intensity. We find that the derived parameters remain nearly constant over time with a temperature around 2 MK, suggesting the emission is dominated by X-ray Bright Points (XBPs). We also obtain the abundances of Mg, Al, and Si relative to H, and find that the FIP bias is ~2, lower than the values observed in active regions.

Non-Pauli Errors in the Three-Dimensional Surface Code

description: A powerful feature of stabiliser error correcting codes is the fact that stabiliser measurement projects arbitrary errors to Pauli errors, greatly simplifying the physical error correction process as well as classical simulations of code performance. However, logical non-Clifford operations can map Pauli errors to non-Pauli (Clifford) errors, and while subsequent stabiliser measurements will project the Clifford errors back to Pauli errors the resulting distributions will possess additional correlations that depend on both the nature of the logical operation and the structure of the code. Previous work has studied these effects when applying a transversal $T$ gate to the three-dimensional colour code and shown the existence of a non-local "linking charge" phenomenon between membranes of intersecting errors. In this work we generalise these results to the case of a $CCZ$ gate in the three-dimensional surface code and find that many aspects of the problem are much more easily understood in this setting. In particular, the emergence of linking charge is a local effect rather than a non-local one. We use the relative simplicity of Clifford errors in this setting to simulate their effect on the performance of a single-shot magic state preparation process (the first such simulation to account for the full effect of these errors) and find that their effect on the threshold is largely determined by probability of $X$ errors occurring immediately prior to the application of the gate, after the most recent stabiliser measurement.
description: 15 pages (+ 8 page appendices), 11 figures; v2 added additional simulation results for the case of depolarising errors occuring immediately before the application of the CCZ gate. Added additional references

Also the method used to extract Fpi from the measured longitudinal cross section was critically reconsidered. Final values for the separated longitudinal and transverse cross sections and the extracted values of Fpi are presented.

description: The comparative study of monasticism in pre-Norman Ireland and Asia Minor during the early Byzantine period reveals, despite their different social backgrounds and cultural heritage, common spiritual loci stemming from common spiritual roots. The writer claims that their similar attitude towards the pre-Christian tradition is a main feature of their common way of thinking, but presents the insistence of the early Irish monastic upon the Christological and Trinitarian teaching of the Greek Fathers as the main reason for the spiritual affinity between Celtic and Byzantine monasticism. This strong affinity is expressed not only in theology but also in the interpretation and organization of monastic life, in which the charismatic dimension takes precedence over institutional elements. The study covers such theological matters as Tranitarian doctrine and the place of man within the world as an imago Dei, and also examines susch controversial issues as penitential practices, the relationship between institutions and charisma, and the characteristics and the role of the Holy Man. In both traditions the spiritual life is delineated as life in the Spirit, leading from catharsis to deification, that is, actual participation in the ineffable and unapproachable Divine nature

description: We describe a fault-tolerant version of the one-way quantum computer using a cluster state in three spatial dimensions. Topologically protected quantum gates are realized by choosing appropriate boundary conditions on the cluster. We provide equivalence transformations for these boundary conditions that can be used to simplify fault-tolerant circuits and to derive circuit identities in a topological manner. The spatial dimensionality of the scheme can be reduced to two by converting one spatial axis of the cluster into time. The error threshold is 0.75% for each source in an error model with preparation, gate, storage and measurement errors. The operational overhead is poly-logarithmic in the circuit size.

(Βάσει του νόμου οι παλιές κοινότητες συγχωνεύτηκαν σε δήμους, οι οποίοι αναλαμβάνουν την τοπική ανάπτυξη της περιοχής τους).

Ο "Καποδίστριας εξετάζεται "εκ των έσω" δηλ. από τη σκοπιά των φορέων της τοπικής αύτοδιοίκησης καθώς επίσης και των υποκειμένων που βιώνουν και ερμηνεύουν τις συνέπειές του αναδεικνύοντας τις συγκλίσεις και αποκλίσεις μεταξύ τους
description: The doctoral thesis examines the administrative reordering and the new spacial classification, which emerged with the 2539/97 Law, known as "Kapodistrias" law, within the framework of the modernization of local administration. (According to the law, old communities have merged into municipalities, taking charge of the local developemnt of their areas). The central question concerns the ways that "kapodistrias" law id socially interpreted and culturally implemented on a local level, in particular, in the municipalities of Axioupoli and Herso, in the prefecture of Kilkis. Focusing on the municipal elections and thecultural events of the newlly-extended municipalities, we are examining the way villages are represented, and how local agents are claiming or reinterpreting their local identity and particularly in the present. "Kapodistrias" law is being examined "from within" which means from the viewpoint of the agents of local administration, as well as of the subjects experiencing and interpreting its consequences, designating the convergences and divergences between them

description: We show that an effective quadratic Zeeman effect can be generated in $^{52}$Cr by proper laser configurations, and in particular by the dipole trap itself. The induced quadratic Zeeman effect leads to a rich ground-state phase diagram, can be used to induce topological defects by controllably quenching across transitions between phases of different symmetries, allows for the observability of the Einstein-de Haas effect for relatively large magnetic fields, and may be employed to create $S=1/2$ systems with spinor dynamics. Similar ideas could be explored in other atomic species opening an exciting new control tool in spinor systems.

description: Solar flares, with energies ranging over several orders of magnitude, result from impulsive release of energy due to magnetic reconnection in the corona. Barring a handful, almost all microflares observed in X-rays are associated with the solar active regions. Here we present, for the first time, a comprehensive analysis of a large sample of quiet Sun microflares observed in soft X-rays by the Solar X-ray Monitor (XSM) on board the Chandrayaan-2 mission during the 2019-20 solar minimum. A total of 98 microflares having peak flux below GOES A-level were observed by the XSM during observations spanning 76 days. By using the derived plasma temperature and emission measure of these events obtained by fitting the XSM spectra along with volume estimates from concurrent imaging observations in EUV with the Solar Dynamics Observatory/Atmospheric Imaging Assembly (SDO/AIA), we estimated their thermal energies to be ranging from 3e26 to 6e27 erg. We present the frequency distribution of the quiet Sun microflares with energy and discuss the implications of these observations of small-scale magnetic reconnection events outside active regions on coronal heating.

Very Large Excesses of 18O in Hydrogen-Deficient Carbon and R Coronae Borealis Stars: Evidence for White Dwarf Mergers

description: We have found that at least seven hydrogen-deficient carbon (HdC) and R Coronae Borealis (RCB) stars, have 16O/18O ratios close to and in some cases less than unity, values that are orders of magnitude lower than measured in other stars (the Solar value is 500). Greatly enhanced 18O is evident in every HdC and RCB we have measured that is cool enough to have detectable CO bands. The three HdC stars measured have 16O/18O < 1, lower values than any of the RCB stars. These discoveries are important clues in determining the evolutionary pathways of HdC and RCB stars, for which two models have been proposed: the double degenerate (white dwarf (WD) merger), and the final helium-shell flash (FF). No overproduction of 18O is expected in the FF scenario. We have quantitatively explored the idea that HdC and RCB stars originate in the mergers of CO- and He-WDs. The merger process is estimated to take only a few days, with accretion rates of 150 Msun/ yr producing temperatures at the base of the accreted envelope of 1.2 - 1.9 x 10^8 K. Analysis of a simplified one-zone calculation shows that nucleosynthesis in the dynamically accreting material may provide a suitable environment for a significant production of 18O, leading to very low values of 16O/18O, similar to those observed. We also find qualitative agreement with observed values of 12C/13C and with the CNO elemental ratios. H-admixture during the accretion process from the small H-rich C/O WD envelope may play an important role in producing the observed abundances. Overall our analysis shows that WD mergers may very well be the progenitors of O18-rich RCB and HdC stars, and that more detailed simulations and modeling are justified.

description: Le développement accéléré des services et des techniques nouvelles transforme non seulement notre existence quotidienne par leurs applications spectaculaires, telle que "l'électronique, mais exerce aussi une influence considérable sur les structures économiques et sociales. La concentration des entreprises, le développement des sociétés à vocation internationale à l'échelon des économies de grand espace, l'avènement d'un nouveau type de dirigeants d'entreprise, sont des phénomènes parmi tant d'autres qui modifient le milieu où s'exercera demain la profession comptable. L'évolution que connaît la comptabilité ces dernières années est caractérisée par des actions de plus en plus grandes et universelles, d'uniformisation et d'harmonisation. La normalisation que cela implique au niveau tant national, régional que mondial, met un accent particulier sur les méthodes comptables qui paraissent les plus appropriées. L'objectif essentiel de cette recherche donc de former des esprits capables de s’adapter à une transformation continue des méthodes et des techniques comptables. Les progrès des études de comptabilité dans le monde international des universités doivent donner une impulsion puissante à l'extension des objectifs et au progrès des normes valables à la fois sur le plan national et sur le plan international. L'étude des expériences tentées dans différents pays sur l'échiquier international nous permettra de mieux comprendre les modèles des systèmes comptables développés et de relever certaines analogies et convergences qui font progresser la doctrine comptable et la comptabilité elle-même.
Os Corpos Celestes São Projeções da Quarta Dimensão? Uma Teoria Fora da Caixa

description: Este trabalho apresenta uma teoria original que propõe que todos os corpos celestes — como estrelas, planetas, luas, buracos negros e galáxias — são manifestações ou projeções de estruturas existentes na quarta dimensão. Assim como uma sombra bidimensional é a projeção de um objeto tridimensional, esses corpos seriam projeções tridimensionais de entidades ou sistemas quadridimensionais. A teoria sugere que o que percebemos como estático ou fixo nos céus é, na verdade, apenas uma fração visível de uma realidade muito maior e dinâmica, que escapa à percepção humana comum. Essa visão se conecta com antigas tradições espirituais e filosóficas, e propõe uma nova forma de compreender o universo e nosso lugar nele.

description: We present a comprehensive study on the silver bismuthate Ag$_2$BiO$_3$, synthesized under high-pressure high-temperature conditions, which has been the subject of recent theoretical work on topologically complex electronic states. We present X-ray photoelectron spectroscopy results showing two different bismuth states, and X-ray absorption spectroscopy results on the oxygen $K$-edge showing holes in the oxygen bands. These results support a bond disproportionated state with holes on the oxygen atoms for Ag$_2$BiO$_3$. We estimate a band gap of $\sim$1.25~eV for Ag$_2$BiO$_3$ from optical conductivity measurements, which matches the band gap in density functional calculations of the electronic band structure in the non-symmorphic space group $Pnn2$, which supports two inequivalent Bi sites. In our band structure calculations the disproportionated Ag$_2$BiO$_3$ is expected to host Weyl nodal chains, one of which is located $\sim$0.5~eV below the Fermi level. Furthermore, we highlight similarities between Ag$_2$BiO$_3$ and the well-known disproportionated bismuthate BaBiO$_3$, including breathing phonon modes with similar energy. In both compounds hybridization of Bi-$6s$ and O-$2p$ atomic orbitals is important in shaping the band structure, but in contrast to the Ba-$5p$ in BaBiO$_3$, the Ag-$4d$ bands in Ag$_2$BiO$_3$ extend up to the Fermi level.

description: Using a first-principles cluster expansion, we shed light on the solid-state phase diagram and structure of the recently discovered high-performance thermoelectrics, Pb-Ag-Sb-Te alloys. The observed nanoscale inhomogeneities are shown to be coherent precipitates of ordered (Ag)m(Sb)n(Te)m+n phases, such as AgSbTe2, all immiscible with rocksalt PbTe. The solubility is high for PbTe in AgSbTe2 and low for (Ag,Sb)Te in PbTe (8% vs. 0.6% at 850 K). The differences in the phonon spectra of PbTe and AgSbTe2 confirm that the inhomogeneities enhance the thermoelectric performance.

description: The dissertation deals with finding new discrete linear and nonlinear transforms and the formation of new algorithms capable extracting local information and finding non linear structures, hidden grammar and periodicity of information. We construct a class of iniertible square sparse matrices in a sense that these matrices result from a recursive procedure with the use of dilation and union operators. These matrices compose a multiscale analysis in the space of sequences of finite length, that provide control of local information. We use the properties of the matrices to develop a prediction model for nearly periodic sequences. We construct non linear invertilbe transforms of RIESZ products of the above matrices and we develop cipher method

description: The miscible displacement of a shear-thinning fluid by another of same rheological properties is studied experimentally in a transparent fracture by an optical technique imaging relative concentration distributions. The fracture walls have complementary self-affine geometries and are shifted laterally in the direction perpendicular to the mean flow velocity {\bf U} : the flow field is strongly channelized and macro dispersion controls the front structure for Péclet numbers above a few units. The global front width increases then linearly with time and reflects the velocity distribution between the different channels. In contrast, at the local scale, front spreading is similar to Taylor dispersion between plane parallel surfaces. Both dispersion mechanisms depend strongly on the fluid rheology which shifts from Newtonian to shear-thinning when the flow rate increases. In the latter domain, increasing the concentration enhances the global front width but reduces both Taylor dispersion (due to the flattening of the velocity profile in the gap of the fracture) and the size of medium scale front structures.

description: We present results of Swift optical, UV and X-ray observations of the afterglow of GRB 050801. The source is visible over the full optical, UV and X-ray energy range of the Swift UVOT and XRT instruments.Both optical and X-ray lightcurves exhibit a broad plateau (Δt/t ~ 1) during the first few hundred seconds after the gamma-ray event. We investigate the multiwavelength spectral and timing properties of the afterglow, and we suggest that the behaviour at early times is compatible with an energy injection by a newly born magnetar with a period of a few tenths of a millisecond, which keeps the forward shock refreshed over this short interval by irradiation. Reverse shock emission is not observed. Its suppression might be due to GRB ejecta being permeated by high magnetic fields, as expected for outflows powered by a magnetar.Finally, the multiwavelength study allows a determination of the burst redshift, z=1.56.

Security proof of a three-state quantum key distribution protocol without rotational symmetry

description: Standard security proofs of quantum key distribution (QKD) protocols often rely on symmetry arguments. In this paper, we prove the security of a three-state protocol that does not possess rotational symmetry. The three-state QKD protocol we consider involves three qubit states, where the first two states, |0_z> and |1_z>, can contribute to key generation and the third state, |+>=(|0_z>+|1_z>)/\sqrt{2}, is for channel estimation. This protocol has been proposed and implemented experimentally in some frequency-based QKD systems where the three states can be prepared easily. Thus, by founding on the security of this three-state protocol, we prove that these QKD schemes are, in fact, unconditionally secure against any attacks allowed by quantum mechanics. The main task in our proof is to upper bound the phase error rate of the qubits given the bit error rates observed. Unconditional security can then be proved not only for the ideal case of a single-photon source and perfect detectors, but also for the realistic case of a phase-randomized weak coherent light source and imperfect threshold detectors. Our result on the phase error rate upper bound is independent of the loss in the channel. Also, we compare the three-state protocol with the BB84 protocol. For the single-photon source case, our result proves that the BB84 protocol strictly tolerates a higher quantum bit error rate than the three-state protocol; while for the coherent-source case, the BB84 protocol achieves a higher key generation rate and secure distance than the three-state protocol when a decoy-state method is used.

description: Gate-all-around nanowire transistor, due to its extremely tight electrostatic control and vertical integration capability, is a highly promising candidate for sub-5 nm technology node. In particular, the junctionless nanowire transistors are highly scalable with reduced variability due to avoidance of steep source/drain junction formation by ion implantation. Here we demonstrate a dual-gated junctionless nanowire \emph{p}-type field effect transistor using tellurium nanowire as the channel. The dangling-bond-free surface due to the unique helical crystal structure of the nanowire, coupled with an integration of dangling-bond-free, high quality hBN gate dielectric, allows us to achieve a phonon-limited field effect hole mobility of $570\,\mathrm{cm^{2}/V\cdot s}$ at 270 K, which is well above state-of-the-art strained Si hole mobility. By lowering the temperature, the mobility increases to $1390\,\mathrm{cm^{2}/V\cdot s}$ and becomes primarily limited by Coulomb scattering. \txc{The combination of an electron affinity of $\sim$4 eV and a small bandgap of tellurium provides zero Schottky barrier height for hole injection at the metal-contact interface}, which is remarkable for reduction of contact resistance in a highly scaled transistor. Exploiting these properties, coupled with the dual-gated operation, we achieve a high drive current of $216\,\mathrm{μA/μm}$ while maintaining an on-off ratio in excess of $2\times10^4$. The findings have intriguing prospects for alternate channel material based next-generation electronics.

description: The second order perturbative field equations for slowly and rigidly rotating perfect fluid balls of Petrov type D are solved numerically. It is found that all the slowly and rigidly rotating perfect fluid balls up to second order, irrespective of Petrov type, may be matched to a possibly non-asymptotically flat stationary axisymmetric vacuum exterior. The Petrov type D interior solutions are characterized by five integration constants, corresponding to density and pressure of the zeroth order configuration, the magnitude of the vorticity, one more second order constant and an independent spherically symmetric second order small perturbation of the central pressure. A four-dimensional subspace of this five-dimensional parameter space is identified for which the solutions can be matched to an asymptotically flat exterior vacuum region. Hence these solutions are completely determined by the spherical configuration and the magnitude of the vorticity. The physical properties like equations of state, shapes and speeds of sound are determined for a number of solutions.

Insitu measurement of dynamic soil properties with emphasis on damping
Creators: name: Stewart, William Patrick
Publisher: name: University of British Columbia
Year: 2009

description: Measurements of the shear wave velocity (Vs) of near-surface soils by downhole and crosshole techniques have become fairly common, including the use of the seismic cone penetration test (SCPT) both at UBC and commercially. A full trace (typically in the order of 400ms long) of the received signal is normally recorded at selected depths, but traditionally only one point is used to determine Vs,. This research is to determine if, these records could provide, at minimal cost, further information on soil properties. Initially alternate methods of Vs calculation were investigated, but the main thrust of this research was use of the amplitude information in the signals to determine bow-strain damping. A variety of equipment; including three source types (mechanical swing hammer, Buffalo gun, and drop weight), three types of receivers (accelerometer, geophone, and bender), and the use of two cones; has been investigated and used for SCPTrs at several sites. The nature of the measured signals in both the time and frequency domain has been investigated and the importance of windowing to isolate the shear wave from the balance of the signal has been clearly demonstrated. The cross-over method of velocity determination has been most commonly used at UBC. Two other methods (cross-correlation and phase of cross-spectrum) have been developed and compared. The recommended approach is the phase of the cross-spectrum method applied to windowed signals. Five methods of damping calculation have been considered in some detail. Three of the methods (rise time, attenuation coefficient, and spectral ratio slope{SRS)) were available in the literature, and the other two methods (modified SHAKE and damping spiral) were developed as part of this research. The most general is the damping spiral method, and it can be shown that the SRS method is a special case of the damping spiral approach. The SRS method is applied simultaneously for several depths within a soil layer, eliminates geometric corrections and was found to be the most accurate approach. Attempts were made to evaluate damping from actual earthquake records, both local (Pender Island earthquake, using SHAKE) and foreign (Eotung array, Taiwan, using the SRS method), but met with little success. Specific recommendations have been developed for all three facets of the measurement and calculation of damping. It has been shown that these recommendations lead to results that are repeatable and that are consistent with both laboratory and published values, for both shear wave velocities and damping.

description: We perform force-free simulations for a neutron star orbiting a black hole, aiming at clarifying the main magnetosphere properties of such binaries towards their innermost stable circular orbits. Several configurations are explored, varying the orbital separation, the individual spins and misalignment angle among the magnetic and orbital axes. We find significant electromagnetic luminosities, $L\sim 10^{42-46} \, [B_{\rm pole}/ 10^{12}{\rm G}]^2 \, {\rm erg/s}$ (depending on the specific setting), primarily powered by the orbital kinetic energy, being about one order of magnitude higher than those expected from unipolar induction. The systems typically develop current sheets that extend to long distances following a spiral arm structure. The intense curvature of the black hole produces extreme bending on a particular set of magnetic field lines as it moves along the orbit, leading to magnetic reconnections in the vicinity of the horizon. For the most symmetric scenario (aligned cases), these reconnection events can release large-scale plasmoids that carry the majority of the Poynting fluxes. On the other hand, for misaligned cases, a larger fraction of the luminosity is instead carried outwards by large-amplitude Alfv{é}n waves disturbances. We estimate possible precursor electromagnetic emissions based on our numerical solutions, finding radio signals as the most promising candidates to be detectable within distances of $\lesssim 200$\,Mpc by forthcoming facilities like the Square Kilometer Array.
