description: Observations from the Space Telescope Imaging Spectrograph define the flux of the DBQ4 star LDS749B from 0.12-1.0 μm with an uncertainty of ~1% relative to the three pure hydrogen WD primary HST standards. With T_{eff}=13575 K, log g=8.05, and a trace of carbon at <1x10^{-6} of solar, a He model atmosphere fits the measured STIS fluxes within the observational noise, except in a few spectral lines with uncertain physics of the line broadening theory. Upper limit to the atmospheric hydrogen and oxygen fractions by number are 1x10^{-7} and 7x10^{-10}, respectively. The excellent agreement of the model flux distribution with the observations lends confidence to the accuracy of the modeled IR fluxes beyond the limits of the STIS spectrophotometry. The estimated precision of ~1% in the predicted IR absolute fluxes at 30 μm should be better than the model predictions for Vega and should be comparable to the absolute accuracy of the three primary WD models.

description: In the present dissertation the law regime that regulates the overrating and/ or the under pricing of the transactions amongst members of the same group of enterprises is analyzed. More specifically, the legal frame is described as this was in effect in our country, and mainly the article of 39 Code of Taxation of Income, before the enactment of Law 3775/2009 (OFFICIAL JOURNAL OF THE HELLENIC REPUBLIC, A' 122/21-7-2009), the significances of overrating and under pricing are clarified and a reference is made to the market regulation provision of article 26 Law 3728/2008. Then, the modifications which the Law 3775/2009 amended to the article 39 are presented, as well as the provisions of the new article 39A. Then, the Directive 90/436/EEC is revised, on the evasion of double taxation at international level. Finally, certain conclusions are formulated in brief and an effort is made to propose solutions for the confrontation of the weaknesses of the legal regime.

On the Path-Integral Derivation of the Anomaly for the Hermitian Equivalent of the Complex $PT$-Symmetric Quartic Hamiltonian

description: It can be shown using operator techniques that the non-Hermitian $PT$-symmetric quantum mechanical Hamiltonian with a "wrong-sign" quartic potential $-gx^4$ is equivalent to a Hermitian Hamiltonian with a positive quartic potential together with a linear term. A naive derivation of the same result in the path-integral approach misses this linear term. In a recent paper by Bender et al. it was pointed out that this term was in the nature of a parity anomaly and a more careful, discretized treatment of the path integral appeared to reproduce it successfully. However, on re-examination of this derivation we find that a yet more careful treatment is necessary, keeping terms that were ignored in that paper. An alternative, much simpler derivation is given using the additional potential that has been shown to appear whenever a change of variables to curvilinear coordinates is made in a functional integral.

Η πρώτη καταφεύγει στη χρήση των περίπλοκων συστημάτων της αστρολογίας, ενώ η δεύτερη έχει απλοϊκότερη μορφή και εξαντλείται με την κά-θετη επίδραση των αστερισμών και των πλανητών πάνω στα βότανα, τους λίθους ή σε άλλα υλικά, ενώ ενέχει σε μεγάλο βαθμό και μαγικά στοιχεία.
description: Medical astrology is an important part of ancient astrology and its beginnings are found in Hellenistic and Greco-Roman period. Medical astrology is divided in two basic parts: the iatromathematica on the one hand and the astrological botanology and the construction of astrological amulets on the other. The former uses the complicated systems of astrology while the latter has simpler form and is consisted of the vertical influence of the stars and the planets on plants, stones or other materials, and it in-cludes many magical elements.

description: Supersymmetric bosonic backgrounds governed by first-order BPS equations, can be realised in a much broader setting by relaxing the requirement of closure of the superalgebra beyond the level of quadratic fermion terms. The resulting pseudo-supersymmetric theories can be defined in arbitrary spacetime dimensions. We focus here on the ${\cal N}=1$ pseudo-supersymmetric extensions of the arbitrary-dimensional bosonic string action, which were constructed a few years ago. In this paper, we recast these in the language of generalised geometry. More precisely, we construct the action and the corresponding supersymmetry transformation rules in terms of O($D$)$\times$O($D$) covariant derivatives, and we discuss consistent truncations on manifolds with generalised $G$-structure. As explicit examples, we discuss Minkowski$\times G$ vacuum solutions and their corresponding pseudo-supersymmetry. We also briefly discuss squashed group manifold solutions, including an example with a Lorentzian signature metric on the group manifold $G$.

description: Σε αυτή την εργασία ασχοληθήκαμε με την ανάπτυξη και υλοποίηση ενός αλγορίθμου τύπου Gradient για την επίλυση του προβλήματος της βέλτιστης κατανομής των αποθηκευτικών χώρων σε μια γραμμή παραγωγής. Η μέθοδος βασίστηκε σε αυτήν που πρότειναν οι Gershwin και Schor (2000) και τροποποιήθηκε ώστε να μπορεί να συνεργαστεί με την εκτιμητική μέθοδο που αναπτύχθηκε από τους Diamantidis, Heavey και Papadopoulos (2005). Με τη συγκεκριμένη υλοποίηση πειραματιστήκαμε για πρώτη φορά με έναν αλγόριθμο τύπου Gradient σε σειριακές, διακριτές και αξιόπιστες γραμμές παραγωγής, στις οποίες κάθε σταθμός εργασίας μπορεί να αποτελείται από παράλληλες μηχανές. Επίσης, δημιουργήθηκαν υβριδικές μέθοδοι όπου ο αλγόριθμος συνδυάζεται με δύο άλλες διαδικασίες, μια Heuristic μέθοδο και μια διαδικασία Nested Partitions (NP). Πραγματοποιήθηκε για πρώτη φορά πειραματισμός της συγκεκριμένης μεθόδου σε γραμμές παραγωγής διαφόρων μεγεθών και σύγκριση αποτελεσμάτων με άλλους αλγορίθμους. Τα αποτελέσματα δείχνουν ότι ο αλγόριθμος έχει πολύ καλή συμπεριφορά και το σφάλμα απόδοσης είναι τις περισσότερες φορές μικρότερο του 1%. Η υβριδική μέθοδος Gradient – Heuristic δίνει επίσης πολύ καλά αποτελέσματα, ενώ η NP – Gradient υστερεί σε απόδοση και υπάρχουν υπολογιστικοί περιορισμοί. Από την άποψη χρονικών απαιτήσεων της CPU, η προτεινόμενη μέθοδος παρουσιάζεται πολύ ταχύτερη από όλες τις διαδικασίες με τις οποίες τη συγκρίναμε, ακόμη και σε μεγάλες γραμμές παραγωγής.
description: In this work we effectuate a Gradient method for the resolution of the Buffer Allocation Problem (BAP). The original method was proposed by Gershwin and Schor (2000) and it was modified so that it can collaborate with an estimative function, proposed by Diamantidis, Heavey and Papadopoulos (2005). Using this effectuation we were able to conduct experiments in serial, distinguishable and reliable production lines, in which each work station can be constituted of parallel machines. This is the first time that experimentation and comparison of results with other algorithms of the particular method was conducted. Moreover we developed two hybrid methods, in which the Gradient collaborates with other algorithms (Heuristic and NP). The results show that the algorithm works well and the performance fault is in the most cases lesser than 1%. The hybrid Gradient – Heuristic gives also very good results, but the NP – Gradient has worse performance and there are computational limits. From the standpoint of CPU time requirements, the proposed method was proved much faster than all the others that it was compared with, even in big production lines.

description: We prove a global fixed point theorem for the centralizer of a homeomorphism of the two dimensional disk $D$ that has attractor-repeller dynamics on the boundary with at least two attractors and two repellers. As one application, we show that there is a finite index subgroup of the centralizer of a pseudo-Anosov homeomorphism with infinitely many global fixed points. As another application we give an elementary proof of Morita's Theorem, that the mapping class group of a closed surface $S$ of genus $g$ does not lift to the group of diffeormorphisms of $S$ and we improve the lower bound for $g$ from 5 to 3.

description: We study an atomic comagnetometer design based on the spin precessions of $^{129}$Xe and $^{131}$Xe atoms in glass cells. The quadrupole splittings in the precession spectrum of $^{131}$Xe are fully resolved, allowing a precise determination of the magnetic-dipole precession frequency. The transverse asymmetry of quadrupole interactions, due to both the geometry and surface properties of the cell, characterized by a non-zero asymmetry parameter $η$, modifies the dependence of the quadrupole splittings on the relative orientation between the cell axes and the bias magnetic field, and lead to additional corrections in the precession frequencies of $^{131}$Xe atoms. We examine these effects both theoretically and experimentally, and develop methods to quantify and control such shifts.

Εμφανίζεται με ρομβοεδρική δομή με τρεις ομάδες των πέντε στρώσεων με την ακολουθία Te1 – Bi – Te2 – Bi – Te1. Η ενίσχυση του υλικού (πρόσμειξη) με Ge οδηγεί στην σύνθεση συνεχών σειρών μονοδιάστατων υπερδομών, που αποτελούνται από ακολουθίες ομάδων των 5 και 7 στρώσεων. Έγιναν παρατηρήσεις δειγμάτων από κρυστάλλους (Bi,Ge)2+xTe3, με x<1, με την Ηλεκτρονική Μικροσκοπία. Η περίθλαση ηλεκτρονίων και η HRTEM, αποκάλυψαν την ύπαρξη διαφόρων μελών των εν λόγω σειρών του δείγματος. Η τεχνική της Precession (Μετάπτωση), χρησιμοποιήθηκε για την λήψη κινηματικών εικόνων περίθλασης, κατά μήκος διαφόρων αξόνων ζώνης. Οι εντάσεις των εικόνων μετρήθηκαν από τις ψηφιοποιημένες εικόνες, υποθέτοντας την ύπαρξη Γκαουσιανής κατανομής της έντασης. Η ανάλυση των δεδομένων χρησιμοποιώντας κατάλληλα προγράμματα, καταλήγει στην εξαγωγή της τελικής δομής των ομάδων 7 στρώσεων και εξακριβώνει την θέση των ατόμων Ge στην δομή του υλικού Bi2Te3.
description: Bi2Te3 has some technological importance due to it’s thermoelectric properties. It has a rhombohedral layered structure with three five – layer groups with the sequence Te1 – Bi – Te2 – Bi – Te1. Doping of Bi2Te3 with Ge leads to the formation of a continuous series of 1D superstructures that are built up of sequences of five and seven layer lamellae. Electron microscopy observations of specimens prepared of (Bi,Ge)2+xTe3 with x<1, were performed. Electron diffraction and high resolution electron microscopy reveal the presence of several members of the series in the same specimen. The electron beam precession technique was used in order to obtain kinematical electron diffraction patterns along several zone -axis. The intensities of the spots were measured from digitized images, assuming a Gaussian distribution of the intensity. The analysis of the data using standard software packages yields to the exact structure of the 7 layer lamella and thus to the accurate Ge sites in the Bi2Te3 matrix.

description: Motivated by far-reaching applications ranging from quantum simulations of complex processes in physics and chemistry to quantum information processing, a broad effort is currently underway to build large-scale programmable quantum systems. Such systems provide unique insights into strongly correlated quantum matter, while at the same time enabling new methods for computation and metrology. Here, we demonstrate a programmable quantum simulator based on deterministically prepared two-dimensional arrays of neutral atoms, featuring strong interactions controlled via coherent atomic excitation into Rydberg states. Using this approach, we realize a quantum spin model with tunable interactions for system sizes ranging from 64 to 256 qubits. We benchmark the system by creating and characterizing high-fidelity antiferromagnetically ordered states, and demonstrate the universal properties of an Ising quantum phase transition in (2+1) dimensions. We then create and study several new quantum phases that arise from the interplay between interactions and coherent laser excitation, experimentally map the phase diagram, and investigate the role of quantum fluctuations. Offering a new lens into the study of complex quantum matter, these observations pave the way for investigations of exotic quantum phases, non-equilibrium entanglement dynamics, and hardware-efficient realization of quantum algorithms.

GMRT observations of X-shaped radio sources

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)

description: We present results from a study of X-shaped sources based on observations using the Giant Metrewave Radio Telescope (GMRT). These observations were motivated by our low frequency study of 3C 223.1 (Lal & Rao 2005), an X-shaped radio source, which showed that the wings (or low-surface-brightness jets) have flatter spectral indices than the active lobes (or high-surface-brightness jets), a result not easily explained by most models. We have now obtained GMRT data at 240 and 610 MHz for almost all the known X-shaped radio sources and have studied the distribution of the spectral index across the sources. While the radio morphologies of all the sources at 240 and 610 MHz show the characteristic X-shape, the spectral characteristics of the X-shaped radio sources, seem to fall into three categories, namely, sources in which (A) the wings have flatter spectral indices than the active lobes, (B) the wings and the active lobes have comparable spectral indices, and (C) the wings have steeper spectral indices than the active lobes. We discuss the implications of the new observational results on the various formation models that have been proposed for X-shaped sources.

description: We investigate a scenario where the recently discovered non-thermal hard X-ray emission from the Ophiuchus cluster originates from inverse Compton scattering of energetic electrons and positrons produced in weakly interacting dark matter pair annihilations. We show that this scenario can account for both the X-ray and the radio emission, provided the average magnetic field is of the order of 0.1 microGauss. We demonstrate that GLAST will conclusively test the dark matter annihilation hypothesis. Depending on the particle dark matter model, GLAST might even detect the monochromatic line produced by dark matter pair annihilation into two photons.

Composite targets obtained by addition of BZO powder in molar percents ranging from 2.5 to 7 mol.% have been prepared and characterized. Measurements of the microwave surface impedance indicate a broadened transition in zero field, however compensated by a very large pinning frequency, indicating that while intergrain properties are still to be optimized the effect of nanometric inclusions substantially enhances the intragrain vortex pinning.

Manual training: from idealism to vocationalism
Creators: name: Hurley, John Francis
Publisher: name: University of British Columbia
Year: 2009

description: Manual Training had one of its intellectual origins in Switzerland in the work of Johann Pestalozzi, and was first introduced as a rational, educational programme in Germany by Friedrich Froebel. Pestalozzi and Froebel valued the practical manipulation of physical materials for cultural, educational and psychological reasons. John Dewey, American philosopher, psychologist and educator, believed in these principles and supported the establishment and growth of manual training in the United States. Progressive educators in Canada were important advocates for manual training. A leading "new educator," James Robertson, with the financial backing of William Macdonald, started manual training centres in Canadian schools in 1900. I argue that manual training became part of the Canadian school system for cultural, educational and psychological reasons grounded in the philosophies of Pestalozzi, Froebel and Dewey. The search for social, industrial and educational efficiency, the growth of industrialism, new scientific research, and urban growth were among forces justifying the Royal Commission for Industrial Training and Technical Education in 1914. The Commission provided new reasons and new impetus for manual training in the public school curriculum. Manual Training became a pre-vocational course of study and an introduction to the purely vocational training in High Schools. The vocational function of manual training was reinforced by the Putman-Weir survey of the British Columbia school system in 1925. I conclude with an illustrative portrait of the start of manual training in a mining town, Cumberland, to show the change of purpose of manual training. This investigation was mainly based in library research for historical information. The Robertson evidence was obtained from original documents, and the story of William Macdonald's contribution to manual training required research in McGill University and Macdonald College, Montreal. Manual Training as a vocational course became part of the superstructure of capitalist society preparing students to fit into the established economic order. One influential administrator, John Kyle, conceived of manual training benefiting students from lower classes.

description: Inspired by the newly reported $Z_{cs}(3985)^{-}$ by the BESIII Collaboration, we systematically investigate the strange hidden-charm tetraquark systems $cs\bar{c}\bar{u}$ with two structures: meson-meson and diquark-antidiquark. Two quark models: the chiral quark model (ChQM) and the quark delocalization color screening model (QDCSM) are used here. Similar results are obtained in both two quark models. There is no any bound state in either ChQM or QDCSM, which excludes the molecular state explanation ($D_{s}D^{*}/D_{s}^{*}D/D_{s}^{*}D^{*}$) of the reported $Z_{cs}(3985)^{-}$. However, the effective potentials for the diquark-antidiquark $cs\bar{c}\bar{u}$ systems shows the possibility of some resonance states with mass range of $3916.5\sim 3964.6$ MeV for $IJ^{P}=\frac{1}{2} 0^{+}$, $4008.8\sim 4091.2$ MeV for $IJ^{P}=\frac{1}{2} 1^{+}$, $4246.8\sim 4418.1$ MeV for $IJ^{P}=\frac{1}{2} 2^{+}$. So the observed $Z_{cs}(3985)^{-}$ state is possible to be explained as a compact resonance state composed of $cs\bar{c}\bar{u}$ with $IJ^{P}=\frac{1}{2} 0^{+}$ or $IJ^{P}=\frac{1}{2} 1^{+}$. The study of the scattering process of corresponding open channels is under way to check this conclusion.

description: The aim of this thesis is to present the theory of the disturbing function and to apply it to the study of the planar three body problem. More precisely, we develop an algorithm and implement it for the calculation of the expansion of that function. Then, we study the dynamics of our system by finding the families of periodic orbits and by presenting their stability through a symplectic mapping model. We study both the circular and elliptic planar three body problem, assuming that an asteroid is moving under the gravitational pertubation of Jupiter. We investigate the 2:1, 1:2, 3:1 and 1:3 resonances by expanding the disturbing function in a series up to 4th and 6th order and state the differences that arise.

Mansplaining in Academia: Narratives of Women Faculty Members at a University in Cagayan De Oro City
Creators: name: Yasay, Dominic
Publisher: name: Zenodo
Year: 2024

description: This study delves into the experiences of women faculty members at a tertiary university in Cagayan de Oro City who have faced “mansplaining” (a portmanteau of the words “man” and “explain”), a form of gendered communication where men condescendingly explain concepts to women, presuming their ignorance. Employing a descriptive phenomenological approach, I analyzed interviews to uncover the ways mansplaining occurs within academic settings as well as the meanings that women faculty attach to their experiences. Five emergent themes were identified, highlighting the varied manifestations of mansplaining, such as male superiors questioning women's expertise and interrupting them during discussions, which undermines women's contributions and breeds a culture of undervaluation.

These encounters significantly affect women's motivation, engagement, and self-perception, instilling doubt about their capabilities and place within the academic sphere. The participants in this study refrained from attributing mansplaining solely to gender dynamics. Instead, they highlighted the critical need for explicit policies that delineate roles and responsibilities while ensuring that women have the autonomy to express their ideas and assert their expertise confidently, even when diverging from male colleagues' perspectives. These approaches can mitigate mansplaining by fostering an inclusive environment that values and respects women's expertise.

The findings underscore the necessity of creating a supportive academic culture that recognizes and celebrates women's achievements without bias. Highlighting the importance of mentors and a supportive network, the study advocates for a respectful, open, and empowering academic atmosphere conducive to all faculty members' growth, irrespective of gender and position in academia.

In conclusion, this research contributes to the dialogue on gender dynamics in academia, offering insights and recommendations for promoting equity and inclusivity. By addressing the systemic roots of mansplaining, institutions can cultivate a more supportive environment for women, ensuring their contributions are valued and their voices are heard, thus advancing the broader goal of gender equality in academic settings.

description: A finite poset X carries a natural structure of a topological space. Fix a field k, and denote by D(X) the bounded derived category of sheaves of finite dimensional k-vector spaces over X. Two posets X and Y are said to be derived equivalent if D(X) and D(Y) are equivalent as triangulated categories. We give explicit combinatorial properties of a poset which are invariant under derived equivalence, among them are the number of points, the Z-congruency class of the incidence matrix, and the Betti numbers. Then we construct, for any closed subset Y of X, a strongly exceptional collection in D(X) and use it to show an equivalence between D(X) and the bounded derived category of a finite dimensional algebra A (depending on Y). We give conditions on X and Y under which A becomes an incidence algebra of a poset. We deduce that a lexicographic sum of a collection of posets along a bipartite graph is derived equivalent to the lexicographic sum of the same collection along the opposite graph. This construction produces many new derived equivalences of posets and generalizes other well known ones. As a corollary we show that the derived equivalence class of an ordinal sum of two posets does not depend on the order of summands. We give an example that this is not true for three summands.

description: Στον τομέα της τηλεφωνίας, η ποιότητα των υπηρεσιών ορίστηκε από την διεθνή ένωση τηλεπικοινωνιών ως η αθροιστική επίδραση της απόδοσης των υπηρεσιών που καθορίζει τον βαθμό ικανοποίησης του χρήστη. Αυτός ο ορισμός περικλείει την ανθρώπινη αξιολόγηση και απαιτεί μια κατάλληλη υποκειμενική στάθμιση των διαφορετικών ατελειών όπως ο θόρυβος, η ηχώ κ.α.Με την εμφάνιση των ψηφιακών τηλεφωνικών δικτύων νέοι τύποι εξασθενήσεων, όπως το αποτέλεσμα των λανθασμένων bits στην κωδικοποίηση, έκαναν σημαντική την αντικειμενική μέτρηση παραμέτρων που εκφράζουν την ποιότητας υπηρεσιών.Σκοπός της εργασιάς ήταν η εκτέλεση μετρήσεων δεικτών που εκφράζουν την ποιότητα υπηρεσιών που παρέχουν οι τρείς εταιρείες κινητής τηλεφωνίας Cosmote, Vodafone και Wind.Οι μετρήσεις πραγματοποιήθηκαν σε δύο χώρους εμπορικού ενδιαφέροντος στη Θεσσαλονίκη, στην οδό Τσιμισκή και στο εμπορικό κέντρο Cosmos Mediterranean. Στην οδό Τσιμισκή πραγματοποιήθηκαν μετρήσεις σε δυο διαφορετικές χρονικές στιγμές, σε ώρες αιχμής (καθημερινή μεσημέρι) και σε ώρες μη αιχμής (Κυριακή πρωί). Στο εμπορικό κέντρο Cosmos Mediterranean πραγματοποιήθηκαν μετρήσεις για δυο διαφορετικά προφίλ χρηστών (αντρικό και γυναικείο προφίλ).Ο τεχνικός εξοπλισμός που χρησιμοποιήθηκε ήταν το λογισμικό Nemo Handy v.1.90.79, ένα κινητό τηλέφωνο Nokia 6680 και ένας δέκτης GPS Bluetooth.In the field of telephony, quality of service (QoS) was defined by the ITU-T as the collective effect of service performance which determine the degree of satisfaction of a user of the service. This definition includes the human evaluation and demands an appropriate subjective recording of diverse defects such as noise, echo, etc. With the advent of digital telephone networks new types of impairments, such as the effects of bit errors in coding, made important the objective measurements of parameters that express the quality of services. Aim of this work was the implementation of measurements of indicators that express the quality of services that they provide the three companies of mobile telephony Cosmote, Vodafone and Wind. The measurements were realized in two places of commercial interest in Thessalonica, in the Tsimiski road and in the commercial centre Cosmos Mediterranean. In the Tsimiski road were realized measurements in two different time moments, in rush hours (daily midday) and in non rush hours (Sunday mornings). In the commercial centre Cosmos Mediterranean were realized measurements for two different profiles of users (man’s profile and woman’s profile). The technical equipment that was used was the software Nemo Handy v.1.90.79, a mobile telephone Nokia 6680 and a GPS Bluetooth receiver.

description: With the recent addition of the Narrow Field Mode (NFM), the Multi Unit Spectroscopic Explorer (MUSE) integral-field spectrograph on VLT UT4 now offers an AO-corrected field of view of 7.5'' x 7.5'' with a mean resolution of 3000 at 480-930 nm. Using MUSE in NFM we have observed 2MASS J01033563-5515561 (AB) b (Delorme 1 (AB) b), a 47 pc distant 12-14 MJup object orbiting a pair of young M5 stars at 84 AU (Eriksson et al. 2020). Observations covered 2.5 hours and obtained a near-visual spectrum (4750-9350 Å) of this hot, young planet/brown dwarf, in addition to resolving both components of the 0.25’’ binary (Fig. 1). Here we present some highlights from our analysis of Delorme 1 (AB) b in Eriksson et al. (2020, A&A 638, L6). The most interesting one being very strong H𝛼 emission, 17 times the local continuum with a mean equivalent width of -138+-13 Å, accompanied by H𝛽 and weaker He I lines. Together, these lines provide a strong indication that Delorme 1 (AB) b could be actively accreting, possibly putting it at tension with its estimated age of 30-45 Myr, or hinting at the presence of an unusually old disk.

description: Since 1999, we have been conducting a radial velocity survey of 179 K giants using the CAT at UCO/Lick observatory. At present ~20-100 measurements have been collected per star with a precision of 5 to 8 m/s. Of the stars monitored, 145 (80%) show radial velocity (RV) variations at a level >20 m/s, of which 43 exhibit significant periodicities. Our aim is to investigate possible mechanism(s) that cause these observed RV variations. We intend to test whether these variations are intrinsic in nature, or possibly induced by companions, or both. In addition, we aim to characterise the parameters of these companions. A relation between log g and the amplitude of the RV variations is investigated for all stars in the sample. Furthermore, the hypothesis that all periodic RV variations are caused by companions is investigated by comparing their inferred orbital statistics with the statistics of companions around main sequence stars. A strong relation is found between the amplitude of the RV variations and log g in K giant stars, as suggested earlier by Hatzes & Cochran (1998). However, most of the stars exhibiting periodic variations are located above this relation. These RV variations can be split in a periodic component which is not correlated with log g and a random residual part which does correlate with log g. Compared to main-sequence stars, K giants frequently exhibit periodic RV variations. Interpreting these RV variations as being caused by companions, the orbital param eters are different from the companions orbiting dwarfs. Intrinsic mechanisms play an important role in producing RV variations in K giants stars, as suggested by their dependence on log g. However, it appears that periodic RV variations are additional to these intrinsic variations, consistent with them being caused by companions.

description: Stabilization of closed string moduli in toroidal orientifold compactifications of type IIB string theory are studied using constant internal magnetic fields on D-branes and 3-form fluxes that preserve N=1 supersymmetry in four dimensions. Our analysis corrects and extends previous work by us, and indicates that charged scalar VEV's need to be turned on, in addition to the fluxes, in order to construct a consistent supersymmetric model. As an explicit example, we first show the stabilization of all Kahler class and complex structure moduli by turning on magnetic fluxes on different sets of D9-branes that wrap the internal space T^6 in a compactified type I string theory, when a charged scalar on one of these branes acquires a non-zero VEV. The latter can also be determined by adding extra magnetized branes, as we demonstrate in a subsequent example. In a different model with magnetized D7-branes, in a IIB orientifold on T^6/Z_2, we show the stabilization of all the closed string moduli, including the axion-dilaton at weak string coupling g_s, by turning on appropriate closed string 3-form fluxes.
