description: In this paper we studied the fermi arc and the fermi pocket in cuprates in a short-range diagonal stripe phase with wave vectors $(7π/8, 7π/8)$, which reproduce with a high accuracy the positions and sizes of the fermi arc and fermi pocket and the superstructure in cuprates observed by Meng et al\cite{Meng}. The low-energy spectral function indicates that the fermi pocket results from the main band and the shadow band at the fermi energy. Above the fermi energy the shadow band gradually departs away from the main band, leaving a fermi arc. Thus we conclude that the fermi arc and fermi pocket can be fully attributed to the stripe phase but has nothing to do with pairing. Incorporating a d-wave pairing potential in the stripe phase the spectral weight in the antinodal region is removed, leaving a clean fermi pocket in the nodal region.

description: We examine the feasibility of a parity non-conserving (PNC) optical rotation experiment for the $^2$P$_{3/2}\rightarrow ^2$P$_{1/2}$ transition of atomic iodine at 1315 nm. The calculated $E1_{\rm PNC}$ to $M1$ amplitude ratio is $R=0.80(16)\times 10^{-8}$. We show that very large PNC rotations (greater than 10 $μ$rad) are obtained for iodine-atom column densities of $\sim 10^{22}$ cm$^{-2}$, which can be produced by increasing the effective interaction pathlength by a factor of $\sim 10^4$ with a high-finesse optical cavity. The simulated signals indicate that measurement of the nuclear anapole moment is feasible, and that a 1% PNC precision measurement should resolve the inconsistency between previous measurements in Cs and Tl.

description: We investigate the quasinormal spectrum of electromagnetic perturbations of rotating black strings. Among the solutions of Einstein equations in the presence of a negative cosmological constant there are asymptotically anti-de Sitter (AdS) black holes whose horizons have the topology of a cylinder. The stationary version of these AdS black holes represents rotating black strings. The conformal field theory (CFT) dual of a black string lives in a Minkowski space with a compact dimension. On the basis of the AdS/CFT duality, we interpret a CFT plasma moving with respect to the preferred rest frame introduced by the topology as the holographic dual to a rotating black string. We explore the consequences of this correspondence by investigating the electromagnetic perturbations of a black string for different rotation parameter values. As usual the electromagnetic quasinormal modes (QNM) correspond to the poles of retarded Green's functions of $R$-symmetry currents in the boundary field theory. The hydrodynamic regime of the QNM dispersion relations are analytically studied. Finally, we investigate numerically the effect of rotation on all the family of black-string electromagnetic quasinormal modes. We interpret these results from the CFT perspective and notice the emergence of effects like Doppler shift of the frequencies and dilation of the thermalization times.

description: The stem-group euarthropod Anomalocaris canadensis is one of the largest Cambrian animals and is often considered the quintessential apex predator of its time. This radiodont is commonly interpreted as a demersal hunter, responsible for inflicting injuries seen in benthic trilobites. However, controversy surrounds the ability of A. canadensis to use its spinose frontal appendages to masticate or even manipulate biomineralized prey. Here, we apply a new integrative computational approach, combining three-dimensional digital modelling, kinematics, finite-element analysis (FEA) and computational fluid dynamics (CFD) to rigorously analyse an A. canadensis feeding appendage and test its morphofunctional limits. These models corroborate a raptorial function, but expose inconsistencies with a capacity for durophagy. In particular, FEA results show that certain parts of the appendage would have experienced high degrees of plastic deformation, especially at the endites, the points of impact with prey. The CFD results demonstrate that outstretched appendages produced low drag and hence represented the optimal orientation for speed, permitting acceleration bursts to capture prey. These data, when combined with evidence regarding the functional morphology of its oral cone, eyes, body flaps and tail fan, suggest that A. canadensis was an agile nektonic predator that fed on soft-bodied animals swimming in a well-lit water column above the benthos. The lifestyle of A. canadensis and that of other radiodonts, including plausible durophages, suggests that niche partitioning across this clade influenced the dynamics of Cambrian food webs, impacting on a diverse array of organisms at different sizes, tiers and trophic levels.

description: This study aimed to assess the accuracy and factors influencing blood alcohol concentration self-estimation during voluntary breath testing. It also aimed to assess whether intended drinking behaviour changed after reviewing blood alcohol concentration and factors influencing this. A total of 462 Australian music festival patrons aged 18–40 years completed a survey exploring factors likely to affect estimation accuracy and provided an estimation of their blood alcohol concentration. A breathalyser reading was taken and participants were asked whether reviewing this reading changed their drinking intentions. Most respondents (58.4%) were accurate within 0.02% range, while 11.4% underestimated and 29.1% overestimated. Machine-read blood alcohol concentration was the most significant estimation accuracy predictor. Reviewing their readings changed the intention to drink in one-third of participants, indicating that voluntary breath testing may influence future drinking behaviour. Underestimation was associated with intention to drink less, whilst completing the survey earlier and <1 h since last drink was associated with intention to drink more.

description: We derive an exact solution to the problem of spin snake states induced in a nonhomogeneous magnetic field by a combined action of the Rashba spin-orbit and Zeeman fields. In an antisymmetric magnetic field the spin snake states are nonlocal composite particles, originating from spatially separated entangled spins. Adding an external homogeneous magnetic field breaks the spin-parity symmetry gapping out the spectral branches, which results in a regular beating pattern of the spin current. These new phenomena in a helical liquid of snake states are proposed for an experimental realization.

title: Εκτίμηση της κυκλοφοριακής κατάστασης ανά λωρίδα κυκλοφορίας σε αυτοκινητόδρομο με συνδεδεμένα οχήματα
Creators: name: Φιλοπουλου Ιρις

description: Στο πρώτο μέρος της εργασίας, συλλέχθηκαν μικροσκοπικά στοιχεία κίνησης που διαμορφώνονται από τη πορεία των οχημάτων σε αυτοκινητόδρομο στο Emeryville, της Καλιφόρνιας. Με τη χρήση των στοιχείων αυτών, υπολογίσθηκαν τα δεδομένα της κυκλοφοριακής κατάστασης ανά λωρίδα του αυτοκινητόδρομου κάθε 5 δευτερόλεπτα.
Κατ’ αρχάς, υπολογίσθηκαν τα δεδομένα που είναι απαραίτητα για την ολοκλήρωση της εκτίμησης από το φίλτρο Kalman. Τα δεδομένα αυτά εξήχθησαν από τα συγκεντρωτικά στοιχεία που ανακτώνται από τα οχήματα (μέσω των ενσωματωμένων αισθητήρων GPS) και από τους αισθητήρες που είναι τοποθετημένοι στην είσοδο και την έξοδο του αυτοκινητόδρομου. Τα δεδομένα που υπολογίσθηκαν περιλαμβάνουν, τις ταχύτητες των οχημάτων και  την συνολική ροη στην είσοδο – έξοδο του υπό μελέτη τμήματος, ανά λωρίδα κυκλοφορίας. Στη συνέχεια,  ακολούθησε ο υπολογισμός πρόσθετων δεδομένων (ροής οχημάτων που αλλάζουν λωρίδα) για την ολοκλήρωση της εκτίμησης από το μοντέλο όσον αφορά στα οχήματα που αλλάζουν λωρίδα κυκλοφορίας, με στόχο τη βελτίωση των αποτελεσμάτων. Τέλος υπολογίσθηκαν τα πραγματικά στοιχεία της κίνησης των οχημάτων για την αξιολόγηση των αποτελεσμάτων της εκτίμησης.
Στην επόμενη ενότητα της εργασίας, έγινε εφαρμογή του μοντέλου εκτίμησης με την εισαγωγή των παραπάνω στοιχείων/δεδομένων. Τα αποτελέσματα τις εκτίμησης περιέλαβαν την πυκνότητα των οχημάτων σε κάθε λωρίδα κυκλοφορίας και την ροή τους στη μη μετρήσιμη (δεν υπάρχει αισθητήρας μετρήσεων) ράμπα εισόδου του αυτοκινητοδρόμου. Το μοντέλο εκτίμησης εφαρμόσθηκε και για την περίπτωση που τα οχήματα δεν είναι στο σύνολό τους συνδεδεμένα (δεν διαθέτουν αισθητήρα GPS στο σύνολό τους). Στο τέλος της ενότητας, τα αποτελέσματα του μοντέλου συγκρίθηκαν με τα πραγματικά στοιχεία που έχουν υπολογιστεί στο πρώτο μέρος της εργασίας.
Στην τελευταία ενότητα της εργασίας, εφαρμόσθηκε το μοντέλο εκτίμησης για μια ακόμη φορά με την προσθήκη μοντέλου ροής για τα οχήματα που αλλάζουν λωρίδα. Έτσι και σε αυτή την  περίπτωση, εξήχθησαν νέα αποτελέσματα εκτίμησης της κυκλοφορίας σε λωρίδες του αυτοκινητόδρομου. Τα παραπάνω επαναλήφθηκαν και για τις περιπτώσεις όπου τα οχήματα στον αυτοκινητόδρομο δεν είναι όλα συνδεδεμένα. Τέλος στην ενότητα αυτή, εξετάστηκε αν τα αντίστοιχα αποτελέσματα εκτίμησης είναι βελτιωμένα και αποδεκτά συγκριτικά με τις πραγματικές συνθήκες κυκλοφορίας ανά λωρίδα στο τμήμα του αυτοκινητόδρομου.
Συμπερασματικά προέκυψε ότι το μοντέλο εκτίμησης λειτουργεί ικανοποιητικά σε όλες τις περιπτώσεις και δίνει αποδεκτά αποτελέσματα ακόμη και στις περιπτώσεις όπου τα συνδεδεμένα οχήματα είναι σχετικά περιορισμένα.

description: Substance use behaviours have been found to cluster in youth, and cannabis use has been previously linked to tobacco and e-cigarette use. The objective of the current study was to examine the bidirectional associations between cannabis, e-cigarette, and cigarette use among a large sample of Canadian secondary school students. A sample of students in grades 9–11 (n = 14,652) from Ontario and Alberta, Canada who participated in two waves of the COMPASS Study (Time 1 (T1): 2015–2016; Time 2 (T2): 2016–2017) was identified. Autoregressive cross-lagged models investigated the stability of product use between T1 and T2, as well as the bidirectional associations between current cannabis, e-cigarette, and cigarette use while controlling for demographic covariates. Significant autoregressive and bidirectional associations between all three substances were observed. Students who reported using cigarettes and e-cigarettes at T1 were more likely to report using cannabis at T2. Similarly, students who reported using cannabis at T1 were more likely to report using cigarettes and e-cigarettes at T2. Given the bidirectional associations identified between cannabis, e-cigarette, and cigarette use in this research, continued monitoring of evolving policies related to cannabis and e-cigarette use in Canada is needed. Additionally, school and community-based prevention efforts targeting youth should consider addressing poly-substance use.
The imaginary part of the gravity action and black hole entropy

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: As observed recently in arXiv:1212.2922, the action of General Relativity (GR) in finite spacetime regions has an imaginary part that resembles the Bekenstein entropy. In this paper, we expand on that argument, with attention to different causal types of boundaries. This property of the GR action may open a new approach to the puzzles of gravitational entropy. In particular, the imaginary action can be evaluated for non-stationary finite regions, where the notion of entropy is not fully understood. As a first step in constructing the precise relationship between the imaginary action and entropy, we focus on stationary black hole spacetimes. There, we identify a class of bounded regions for which the action's imaginary part precisely equals the black hole entropy. As a powerful test on the validity of the approach, we also calculate the imaginary action for Lovelock gravity. The result is related to the corresponding entropy formula in the same way as in GR.

Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: The Gross-Pitaevskii equation for polarized molecules is an integro-differential equation, consequently it is complicated for solving. We find a possibility to represent it as a non-integral nonlinear Schrodinger equation, but this equation should be coupled with two linear equations describing electric field. These two equations are the Maxwell equations. We recapture the dispersion of collective excitations in the three dimensional electrically polarized BEC with no evolution of the electric dipole moment directions. We trace the contribution of the electric dipole moment. We explicitly consider the contribution of the electric dipole moment in the interaction constant for the short-range interaction. We show that the spectrum of dipolar BEC reveals no instability at repulsive short-range interaction. Nonlinear excitations are also considered. We present dependence of the bright soliton characteristics on the electric dipole moment.

description: The superfluid phases in the resonant dipolar Fermi gases are investigated by the standard mean-field theory. In contrast to the crossover from Bose-Einstein condensation (BEC) to Bardeen-Cooper-Schrieffer (BCS) superfluid in the Fermi gases with the isotropic interactions, the resonant dipolar interaction leads to two completely different BEC phases of the tight-binding Fermi molecules on both sides of the resonance, which are characterized by two order parameters with the distinct internal symmetries. We point that near the resonance, the two competitive phases can coexist, and an emergent relative phase between the two order parameters spontaneously breaks the time-reversal symmetry, which could be observed in the momentum resolved rf-spectroscopy.

description: In this paper, we study semiparametric estimation for a single-index panel data model where the nonlinear link function varies among the individuals. We propose using the refined minimum average variance estimation method to estimate the parameter in the single-index. As the cross-section dimension N and the time series dimension T tend to infinity simultaneously, we establish asymptotic distributions for the proposed estimator. In addition, we provide a real-data example to illustrate the finite sample behaviour of the proposed estimation method.

description: Using highly efficient GPU-based simulations of the tight-binding Bogoliubov-de Gennes equations we solve self-consistently for the pair correlation in rhombohedral (ABC) and Bernal (ABA) multilayer graphene by considering a finite intrinsic s-wave pairing potential. We find that the two different stacking configurations have opposite bulk/surface behavior for the order parameter. Surface superconductivity is robust for ABC stacked multilayer graphene even at very low pairing potentials for which the bulk order parameter vanishes, in agreement with a recent analytical approach. In contrast, for Bernal stacked multilayer graphene, we find that the order parameter is always suppressed at the surface and that there exists a critical value for the pairing potential below which no superconducting order is achieved. We considered different doping scenarios and find that homogeneous doping strongly suppresses surface superconductivity while non-homogeneous field-induced doping has a much weaker effect on the superconducting order parameter. For multilayer structures with hybrid stacking (ABC and ABA) we find that when the thickness of each region is small (few layers), high-temperature surface superconductivity survives throughout the bulk due to the proximity effect between ABC/ABA interfaces where the order parameter is enhanced.

description: Mass-loss rate, $\dot{M}$, is one of the key parameters affecting evolution and observational manifestations of massive stars, and their impact on the ambient medium. Despite its importance, there is a factor of ~100 discrepancy between empirical and theoretical $\dot{M}$ of late-type O dwarfs, the so-called weak-wind problem. In this Letter, we propose a simple novel method to constrain $\dot{M}$ of runaway massive stars through observation of their bow shocks and Stromgren spheres, which might be of decisive importance for resolving the weak-wind problem. Using this method, we found that $\dot{M}$ of the well-known runaway O9.5 V star zeta Oph is more than an order of magnitude higher than that derived from ultraviolet (UV) line-fitting (Marcolino et al. 2009) and is by a factor of 6 to 7 lower than those based on the theoretical recipe by Vink et al. (2000) and the Halpha line (Mokiem et al. 2005). The discrepancy between $\dot{M}$ derived by our method and that based on UV lines would be even more severe if the stellar wind is clumpy. At the same time, our estimate of $\dot{M}$ agrees with that predicted by the moving reversing layer theory by Lucy (2010).

description: The Heisenberg picture for non-Hermitian but $η$-pseudo-Hermitian Hamiltonian systems is suggested. If a non-Hermitian but $η$-pseudo-Hermitian Hamiltonian leads to real second order equations of motion, though their first order Heisenberg equations of motion are complex, we can construct a Hermitian counterpart that gives the same second order equations of motion. In terms of a similarity transformation we verify the iso-spectral property of the Hermitian and non-Hermitian Hamiltonians and obtain the related eigenfunctions. This feature can be used to determine real eigenvalues for such non-Hermitian Hamiltonian systems. As an application, two new non-Hermitian Hamiltonians are constructed and investigated, where one is non-Hermitian and non-PT-symmetric and the other is non-Hermitian but PT-symmetric. Moreover, the complementarity and compatibility between our treatment and the PT symmetry are discussed.

Ιδιαίτερη προσπάθεια καταβλήθηκε για την ανεύρεση ενός εύκολου και αποτελεσματικού τρόπου θέρμανσης της συναρμολογημένης διάταξης των δακτυλίων, ώστε να προσομοιάζει το θερμό υπέδαφος που πραγματοποιείται η γεώτρηση. Ένα μικρό σπειροειδές κύκλωμα χάλκινων σωληνώσεων τοποθετήθηκε στο κέντρο της διάταξης ως μικρογραφία των αντίστοιχων πραγματικών εγκαταστάσεων. Εναλλάσσοντας το υλικό πλήρωσης της γεώτρησης στη διάταξη έγινε προσπάθεια αξιολόγησης των ιδιοτήτων των υλικών που χρησιμοποιούνται σε τέτοιες γεωθερμικές εγκαταστάσεις.

description: Boltzmann-Gibbs distribution arises as the statistical equilibrium probability distribution of money among the agents of a closed economic system where random and undirected exchanges are allowed. When considering a model with uniform savings in the exchanges, the final distribution is close to the gamma family. In this work, we implement these exchange rules on networks and we find that these stationary probability distributions are robust and they are not affected by the topology of the underlying network. We introduce a new family of interactions: random but directed ones. In this case, it is found the topology to be determinant and the mean money per economic agent is related to the degree of the node representing the agent in the network. The relation between the mean money per economic agent and its degree is shown to be linear.

description: Στην παρούσα διπλωματική εργασία παρουσιάζεται το πρόβλημα αντιμετάθεσης χρονοπρογραμματισμού εργασιών, ένα πρόβλημα με το οποίο έρχονται αντιμέτωπες όλες οι σύγχρονες βιομηχανίες, προκειμένου να αυξήσουν την παραγωγή τους, ελαχιστοποιώντας ταυτόχρονα το κόστος λειτουργίας τους. Πρόκειται για ένα πρόβλημα που αφορά την κατανομή των διαφόρων εργασιών μιας γραμμής παραγωγής στις διαθέσιμες μηχανές με αντικειμενικό στόχο την ελαχιστοποίηση του συνολικού χρόνου επεξεργασίας των εργασιών από τις μηχανές. Ως βασικοί κανόνες αυτού του προβλήματος τίθενται οι εξής: όλες οι εργασίες πρέπει να επεξεργαστούν από όλες τις μηχανές με την ίδια σειρά, οι μηχανές δε μπορούν να διακόψουν τη λειτουργία τους, κάθε χρονική στιγμή μία μηχανή μπορεί να επεξεργαστεί το πολύ μία εργασία και τέλος μία εργασία μπορεί να επεξεργαστεί μόνο από μία μηχανή. Για την επίλυση του συγκεκριμένου προβλήματος επιλέχθηκε ο μεθευρετικός αλγόριθμος της Τεχνητής Αποικίας Μελισσών (Artificial Bee Colony - ABC), ένας αλγόριθμος ο οποίος βασίζεται στην ευφυΐα του σμήνους και όχι στα χαρακτηριστικά του εκάστοτε προβλήματος  προκειμένου να βρει την βέλτιστη λύση. Ο αλγόριθμος αυτός, ιδιαίτερα διαδεδομένος στα συνεχή προβλήματα, τροποποιήθηκε κατάλληλα εδώ προκειμένου να επιλύσει το προαναφερθέν διακριτό πρόβλημα χρονοπρογραμματισμού εργασιών.
Στην  παρούσα εργασία, το πρόβλημα αντιμετάθεσης χρονοπρογραμματισμού εργασιών, αρχικά, εμφανίζεται με τη μορφή θεωρητικών αιτιοκρατικών προβλημάτων από την βιβλιογραφία. Σε αυτά εφαρμόζεται ο διακριτός αλγόριθμος ABC προκειμένου να διαπιστωθεί η αξιοπιστία και ευρωστία του. Εν συνεχεία, μοντελοποιείται ένα πραγματικό σύστημα παραγωγής ενός εργαστηρίου διακρίβωσης και επιλύεται από τον ABC, αρχικά θεωρούμενο ως αιτιοκρατικό πρόβλημα και στη συνέχεια ως στοχαστικό. Από την επίλυση αυτού του συστήματος προκύπτουν αποτελέσματα, μέσα από τα οποία καταλήγουμε σε συμπεράσματα για τη βέλτιστη λειτουργία του συγκεκριμένου συστήματος παραγωγής.
Iron-Based Superconductors as Parity Odd Superconductors

description: Parity is a fundamental quantum number to classify a state of matter. Materials rarely possess ground states with odd parity. We show that the superconducting state in iron-based superconductors is classified as an odd parity s-wave spin-singlet pairing state in a single trilayer FeAs/Se, the building block of the materials. In a low energy effective model constructed on the Fe square bipartite lattice, the superconducting order parameter in this state is a combination of a s-wave normal pairing between two sublattices and a s-wave $η$-pairing within the sublattices. Parity conservation was violated in proposed superconducting states in the past. The state has a fingerprint with a real space sign inversion between the top and bottom As/Se layers. The results demonstrate iron-based superconductors being a new quantum state of matter and suggest that the measurement of the odd parity can establish fundamental principles related to high temperature superconducting mechanism.

Clustering-induced attraction in granular mixtures of rods and spheres

description: Depletion-induced aggregation of rods enhanced by clustering is observed to produce a novel model of attractive pairs of rods separated by a line of spheres in a quasi-2D, vertically-shaken, granular gas of rods and spheres. We show that the stability of these peculiar granular aggregates increases as a function of shaking intensity. Velocity distributions of spheres inside and outside of a pair of rods trapping a line of spheres show a clear suppression of the momentum acquired by the trapped spheres. The condensed phase formed between the rods is caused by a clustering instability of the trapped spheres, enhanced by a vertical guidance produced by the confining rods. The liberated area corresponding to direct excluded-volume pairs and indirect depletion-aggregated pairs is measured as a function of time. The stability of rod pairs mediated by spheres reveals an attraction comparable in strength to the one purely induced by depletion forces.

Initial Planetesimal Sizes and the Size Distribution of Small Kuiper Belt Objects

description: We show, by comparing observations with theoretical models, that the observed Kuiper Belt size distribution is well matched by coagulation models, which start from an initial planetesimal population with radii of about 1km, and subsequent collisional evolution. We find that the observed size distribution for R > 30km has not been modified by collisional evolution over the age of the solar system, and that the size distribution below R ~ 30km has been modified by collisions and that its slope is well matched by collisional evolution models that use published strength laws. We investigate in detail the resulting size distribution of bodies ranging from 0.01km to 30km and find that its slope changes several times as a function of radius before approaching the expected value for an equilibrium collisional cascade of material strength dominated bodies for R < 0.1km. Compared to a single power law size distribution that would span the whole range from 0.01km to 30km, we find a strong deficit of bodies around R ~10km and a strong excess of bodies around 2km. This deficit and excess are caused by an excess mass in small planetesimals in the km size range that was left over from the runaway growth phase and that leaves a signature in the size distribution that is not erased after 4.5 Gyrs of collisional evolution. Observations of the small KBO size distribution can therefore test if large KBOs grew as a result of runaway growth and constrain the initial planetesimal sizes. We find that results from recent KBO occultation surveys and the observed KBO size distribution can be best matched by an initial planetesimal population that contained about equal mass per logarithmic mass bin in bodies ranging from 0.4km to 4km in radius. In addition, we find that we cannot match the observed KBO size distribution if most of the planetesimal mass was contained in bodies that were 10km in radius or larger.

description: We have developed a patch implementing multivariate polynomials seen as a multi-base algebra. The patch is to be released into the software Sage and can already be found within the Sage-Combinat distribution. One can use our patch to define a polynomial in a set of indexed variables and expand it into a linear basis of the multivariate polynomials. So far, we have the Schubert polynomials, the Key polynomials of types A, B, C, or D, the Grothendieck polynomials and the non-symmetric Macdonald polynomials. One can also use a double set of variables and work with specific double-linear bases like the double Schubert polynomials or double Grothendieck polynomials. Our implementation is based on a definition of the basis using divided difference operators and one can also define new bases using these operators.

description: LHS1070 is a nearby multiple system of low mass stars. It is an important source of information for probing the low mass end of the main sequence, down to the hydrogen-burning limit. The primary of the system is a mid-M dwarf and two components are late-M to early L dwarfs, at the star-brown dwarf transition. Hence LHS1070 is a valuable object to understand the onset of dust formation in cool stellar atmospheres.This work aims at determining the fundamental stellar parameters of LHS1070 and to test recent model atmospheres: BT-Dusty,BT-Settl, DRIFT, and MARCS models.Unlike in previous studies, we have performed a chi^2-minimization comparing well calibrated optical and infrared spectra with recent cool star synthetic spectra leading to the determination of the physical stellar parameters Teff, radius, and log g for each of the three components of LHS1070.
