description: Η παρούσα μεταπτυχιακή εργασία μελετά συνολικά το βασιλικό παρεκκλήσι στα Πυργά, της επαρχίας Λάρνακας στην Κύπρο. Στόχος της είναι να παρουσιάσει μια νέα και ολοκληρωμένη ερμηνευτική προσέγγιση των ζητημάτων που απασχόλησαν την επιστημονική έρευνα στο παρελθόν, καθώς και των νεότερων που αναδεικνύονται, με το συνδυασμό ιστορικών και αρχειακών πηγών, με αναφορές στην αρχιτεκτονική και την εικονογραφία του μνημείου και με την αξιοποίηση κάθε άλλης χρήσιμης για την έρευνα πληροφορίας. Διερευνάται η μεσαιωνική ονομασία του οικισμού των Πυργών, ενώ, παράλληλα, επιχειρείται μια νέα ερμηνευτική ανάγνωση της ανάγλυφης επιγραφής «bazoges», στο νότιο υπέρθυρο του ναού. Περαιτέρω, γίνεται ειδική αναφορά στις αρχιτεκτονικές φάσεις του ναού και στα κατάλοιπα παρακείμενου κτίσματος της ίδιας περιόδου, ενώ παρουσιάζεται το εικονογραφικό πρόγραμμα και τα προβλήματα που προκύπτουν κατά την ανάλυσή του. Ως προς το διάκοσμο, προσδιορίζεται η τεχνοτροπία και αναλύονται οι γραπτές επιγραφές και τα μεταγενέστερα χαράγματα. Η ζωγραφική του βασιλικού παρεκκλησίου στα Πυργά αποτελεί ένα από τα καλύτερα δείγματα της περιόδου των Λουζινιάν στην Κύπρο, ενώ ο συνδυασμός βυζαντινών και δυτικών στοιχείων παρέχει ένα ιδιαίτερο εργαλείο αποτίμησης των επί μέρους ζητημάτων του μνημείου.
description: The present master thesis examines the Royal Chapel at Pyrga in the Larnaca district of Cyprus as a whole. The aim of this study is to present a new and interpretive approach to various issues pertaining to the Royal Chapel. New questions were formulated as a result of an interdisciplinary investigation of the historical and archival sources, the architecture and iconography, as well as of any further source material relevant to this subject. In essence, this thesis investigates the medieval name of the village of Pyrga, while attempting a new reading of the incised inscription “bazoges” on the lintel over the southern entrance of the church. Moreover, it closely examines the construction phases of the Chapel while paying particular attention to the ruins of an adjacent building that dates to the same period. It also scrutinizes the iconographical program and studies a number of associated problems. As for the wall paintings, the thesis determines their style, and analyzes their inscriptions and graffiti. It becomes clear that the frescoes of the Royal Chapel are one of the finest examples of the Lusignan period in Cyprus. Additionally, they present a fascinating amalgamation of Byzantine and Western elements.
On the rational approximation of Markov functions,with applications to the computation of Markovfunctions of Toeplitz matrices

description: We investigate the problem of approximating the matrix function $f(A)$ by $r(A)$, with $f$ a Markov function, $r$ a rational interpolant of $f$, and $A$ a symmetric Toeplitz matrix. In a first step, we obtain a new upper bound for the relative interpolation error $1-r/f$ on the spectral interval of $A$. By minimizing this upper bound over all interpolation points, we obtain a new, simple and sharp a priori bound for the relative interpolation error. We then consider three different approaches of representing and computing the rational interpolant $r$. Theoretical and numerical evidence is given that any of these methods for a scalar argument allows to achieve high precision, even in the presence of finite precision arithmetic. We finally investigate the problem of efficiently evaluating $r(A)$, where it turns out that the relative error for a matrix argument is only small if we use a partial fraction decomposition for $r$ following Antoulas and Mayo. An important role is played by a new stopping criterion which ensures to automatically find the degree of $r$ leading to a small error, even in presence of finite precision arithmetic.

description: We present experimental evidence for a hitherto unconfirmed type of angle-dependent magnetoresistance oscillation caused by magnetic breakdown. The effect was observed in the organic superconductor kappa-(BEDT-TTF)$_2$Cu(NCS)$_2$ using hydrostatic pressures of up to 9.8 kbar and magnetic fields of up to 33 T. In addition, we show that similar oscillations are revealed in ambient pressure measurements, provided that the Shubnikov-de Haas oscillations are suppressed either by elevated temperatures or filtering of the data. These results provide a compelling validation of Pippard's semiclassical picture of magnetic breakdown.

The sensors have been tested with a beam of charged particles in two different configurations, perpendicular to and almost parallel to the incident beam. The second approach, known as the grazing angles method, is shown to be a powerful method to investigate not only the charge collection, but also the time-to-threshold properties as a function of the depth at which the charges are liberated.

Επίσης, γίνεται μια προσέγγιση και άλλων επιμέρους ποιημάτων του Φράσερι, με σκοπό μια συνολικότερη παρουσίαση του έργου ενός ποιητή, ο οποίος αν και σημαντικότατος στη χώρα του, παραμένει άγνωστος για τους περισσότερους στην Ελλάδα.
description: The present paper deals with the national poetry as a literary genre that emerged from the political conditions and social needs of the 19th century. The paper is also studying the poetry of two poets who are considered national poets in their country, for different reasons each. It deals namely with the poetry of Dionysios Solomos, Greece's national poet and Naim Frashëri, the respective national poet of Albania. The essay approaches the most popular patriotic poems of these two poets, attempting to reconcile their work and find the similarities and differences in content, philosophical beliefs and messages that Solomos and Frashëri seek to convey to the reader. The examined poems of Solomos are the “Hymn to Liberty” and “Free Besieged”, while the examined poems of Frashëri are Τhe True Desire of Albanians, “Bucolic and Agricultural” and “History of Skanderbeg”. Moreover, there is an overall approach of the poems of Frashëri, which aims to a better presentation of the work of a poet who, although very important in his own country, remains unknown to most in Greece.

description: The leptophilic weakly interacting massive particle (WIMP) is realized in a minimal renormalizable model scenario where scalar mediators with lepton number establish the WIMP interaction with the standard model (SM) leptons. We perform a comprehensive analysis for such a WIMP scenario for two distinct cases with an SU(2) doublet or singlet mediator considering all the relevant theoretical, cosmological and experimental constraints at present. We show that the mono-photon search at near-future lepton collider experiments (ILC, FCC-ee, CEPC, etc.) can play a significant role to probe the yet unexplored parameter range allowed by the WIMP relic density constraint. This will complement the search prospect at the near-future hadron collider experiment (HL-LHC). Furthermore, we discuss the combined model scenario including both the doublet and singlet mediator. The combined model is capable of explaining the long-standing muon (g-2) anomaly which is an additional advantage. We demonstrate that the allowed region for anomalous muon (g-2) explanation, which has been updated very recently at Fermi National Accelerator Laboratory, can also be probed at the future colliders which will thus be a simultaneous authentication of the model scenario.

Constraints on the Massive Supernova Progenitors

description: Generally accepted scheme distinguishes two main classes of supernovae (SNe): Ia resulting from the old stellar population (deflagration of a white dwarf in close binary systems), and SNe of type II and Ib/c whose ancestors are young massive stars (died in a core-collapse explosion). Concerning the latter, there are suggestions that the SNe II are connected to early B stars, and SNe Ib/c to isolated O or Wolf-Rayet (W-R) stars. However, little or no effort was made to further separate SNe Ib from Ic. We have used assumed SN rates for different SN types in spiral galaxies in an attempt to perform this task. If isolated progenitor hypothesis is correct, our analysis indicates that SNe Ib result from stars of main-sequence mass $23 \mathcal{M}_{\odot} \lesssim \mathcal{M} \lesssim 30 \mathcal{M}_{\odot}$, while the progenitors of SNe Ic are more massive stars with $\mathcal{M} \gtrsim 30 \mathcal{M}_{\odot}$. Alternatively, if the majority of SNe Ib/c appear in close binary systems (CBs) then they would result from the same progenitor population as most of the SNe II, i.e. early B stars with initial masses of order $\mathcal{M} \sim 10 \mathcal{M}_{\odot}$. Future observations of SNe at high-redshift ($z$) and their rate will provide us with unique information on SN progenitors and star-formation history of galaxies. At higher-$z$ (deeper in the cosmic past) we expect to see the lack of type Ia events, i.e. the dominance of core-collapse SNe. Better understanding of the stripped-envelope SNe (Ib/c), and their potential use as distance indicators at high-$z$, would therefore be of great practical importance.

description: The purpose of the present master thesis was to investigate the accessibility, professional development and the presence of female teachers in secondary education from 1930 to 1976. The first part, the theoretical one, presents the evolution of women’s education in Greece, in secondary and higher education, from the 19th to the 20th century, women professional activity, their relation to the teaching profession, the professional development and the social activity of the secondary education teachers during the feminist movement from the 19th to the mid 20th century. The second part is the research part and is structured in two chapters. In the first one, the distribution of secondary school teachers is being studied initially by gender and by gender and specialty afterwards, as well as the gender distribution of high-school and secondary high-school headmasters as it was formed by studying the Government Gazette and volumes of National Statistical Service of Greece, while in the second part is investigated, through autobiographical texts, personal and educational experiences of female teachers of secondary education, who taught in the first half of the 20th century.

description: Positive operator valued measurements (POVMs) play an important role in efficient quantum communication and computation. While optical systems are one of the strongest candidates for long distance quantum communication and information processing, efficient methods to implement POVMs in these systems are scarce. Here we propose an all-optical scheme to implement an arbitrary POVM using linear optical components on m-dimensional Hilbert space of internal degrees of freedom. Linear optical nature of the proposed scheme makes it efficient and robust. We show how the scheme can be applied for state tomography and for preparing arbitrary mixed states.

Το ερευνώμενο ζήτημα ανακύπτει μόνο στη δεύτερη περίπτωση, όταν δηλαδή η παράδοση ενός προσώπου ζητείται για το σκοπό παραπομπής του σε δίκη, αφού τότε μόνο ενδέχεται να υποβληθεί μετά την παράδοσή του στην Ελλάδα σε προσωρινή κράτηση. Η προβληματική αναφύεται τόσο στο πεδίο της έκδοσης όσο και στο πεδίο του ευρωπαϊκού εντάλματος σύλληψης, αν και η αντιμετώπισή της δεν είναι κοινή, εξαιτίας της διαφορετικότητας των δύο μηχανισμών διεθνούς δικαστικής συνδρομής.
description: This paper addresses the issue of whether the duration of the detention of a requested person abroad with a view to his extradition to Greece or due to the execution of a European Arrest Warrant should be included in the duration of the pre - trial detention that will be imposed to him following his surrender in Greece. Both extradition and European Arrest Warrant are measures of international judicial assistance aiming at the arrest and surrender of a person to the authorities of the requesting state for the purposes of executing a sentence or conducting a criminal prosecution against him. The issue in question arises only in the second case, since only in this case may the requested person be submitted in pre-trial detention. The problem arises both in extradition and European Arrest Warrant, nevertheless it is not commonly dealt with, because of the diversity of the two international judicial mechanisms.

description: A supergiants are objects in transition from the blue to the red (and vice versa) in the uppermost HRD. They are the intrinsically brightest "normal" stars at visual light with absolute visual magnitudes up to -9. They are ideal to study young stellar populations in galaxies beyond the Local Group to determine chemical composition and evolution, interstellar extinction, reddening laws and distances. We discuss most recent results on the quantitative spectral analysis of such objects in galaxies beyond the Local Group based on medium and low resolution spectra obtained with the ESO VLT and Keck. We describe the analysis method including the determination of metallicity and metallicity gradients. A new method to measure accurate extragalactic distances based on the stellar gravities and effective temperatures is presented, the flux weighted gravity - luminosity relationship (FGLR). The FGLR is a purely spectroscopic method, which overcomes the untertainties introduced by interstellar extinction and variations of metallicity, which plague all photometric stellar distance determination methods. We discuss the perspectives of future work using the giant ground-based telescopes of the next generation such as the TMT, the GMT and the E-ELT.

The political thought of Daniel Dulany, the Elder
Creators: name: Yirush, Craig Bryan
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is an examination of the political thought of Daniel Dulany, the Elder (1689-1753), a leading Maryland lawyer and assemblyman of the early 18th century. Starting with an examination of the structure of Maryland politics up to and including the 1720’s, it argues that Dulany, as the leader of the Maryland lower house, used that institution’s growing powers to make a vigorous challenge to proprietorial rule between 1722 and 1729; and that this challenge was met by an equally strong one from the lord proprietor. The key issue was the lower house’s desire for the extension of the English statutes law. By the late 1720’s, this conflict had resulted in an administrative and political stalemate. The pamphlet that Dulany wrote came out of this context; and this paper argues that it is the best expression of Maryland political thought in the early 18th century. It is also claimed that, because it is one of the earliest surviving southern political writings, it can offer us insight on the nature of ideas available to colonial Americans before the American Revolution. The key concepts in the pamphlet are then examined in detail. A case is made that Dulany has a strong idea of the rights of the individual subject, and that this is the reason why he desires the English statute law. His position on rights is examined, and an argument is made for the influence of John Locke’s idea of natural rights on Dulany. Next the issue of virtue is taken up. Dulany is seen to have a non-civic conception of virtue, one that includes a strong respect for the protection of a private realm. Dulany’s views on the public good are also seen to include a respect for the rights of the subject. Finally it is argued that his desire for the protections afforded by English statute law involves a downp’aying of the role of the active, publicly concerned citizen in favour of a formal legal setup. Lastly, the various sources used in the pamphlet are examined. In the conclusion, a demonstration of the ways in which Dulany ‘s concept of rights contributed to his overall political philosophy is offered. Finally, the reading of Dulany’s pamphlet offered in this thesis is briefly compared to the reading of early modern political theory presented in modern historiography.

description: We present a two-dimensional theoretical model for the slow chemical corrosion of a thin film of a disordered solid by suitable etching solutions. This model explain different experimental results showing that the corrosion stops spontaneously in a situation in which the concentration of the etchant is still finite while the corrosion surface develops clear fractal features. We show that these properties are strictly related to the percolation theory, and in particular to its behavior around the critical point. This task is accomplished both by a direct analysis in terms of a self-organized version of the Gradient Percolation model and by field theoretical arguments.

description: The modulational instability of broadband optical pulses in a four-state atomic system is investigated. In particular, starting from a recently derived generalized nonlinear Schrödinger equation, a wave-kinetic equation is derived. A comparison between coherent and random phase wave states is made. It is found that the spatial spectral broadening can contribute to the nonlinear stability of ultra-short optical pulses. In practical terms, this could be achieved by using random phase plate techniques.

description: Quantum classification and hypothesis testing are two tightly related subjects, the main difference being that the former is data driven: how to assign to quantum states $ρ(x)$ the corresponding class $c$ (or hypothesis) is learnt from examples during training, where $x$ can be either tunable experimental parameters or classical data "embedded" into quantum states. Does the model generalize? This is the main question in any data-driven strategy, namely the ability to predict the correct class even of previously unseen states. Here we establish a link between quantum machine learning classification and quantum hypothesis testing (state and channel discrimination) and then show that the accuracy and generalization capability of quantum classifiers depend on the (Rényi) mutual informations $I(C{:}Q)$ and $I_2(X{:}Q)$ between the quantum state space $Q$ and the classical parameter space $X$ or class space $C$. Based on the above characterization, we then show how different properties of $Q$ affect classification accuracy and generalization, such as the dimension of the Hilbert space, the amount of noise, and the amount of neglected information from $X$ via, e.g., pooling layers. Moreover, we introduce a quantum version of the Information Bottleneck principle that allows us to explore the various tradeoffs between accuracy and generalization. Finally, in order to check our theoretical predictions, we study the classification of the quantum phases of an Ising spin chain, and we propose the Variational Quantum Information Bottleneck (VQIB) method to optimize quantum embeddings of classical data to favor generalization.

description: Phosphate ore, which may be associated with natural radionuclides, has been used for a long time as a builder in detergents. The daily use and discharge of detergents in wastewater may lead to the accumulation of radionuclides in the environment. Therefore, the current study was carried out to determine the radioactivity levels of 226Ra, 232Th, 40K, and 238U in 15 samples of detergent powders that are widely used in Saudi Arabia, using gamma-ray spectrometry (HPGe). The results showed that these radionuclides were below or similar to the recommended limits, except 238U in two types of detergent powders. Further, radium equivalent activity (Raeq), the outdoor and indoor absorbed dose rate (D), and annual effective dose (E) were calculated to assess the radiological hazard effects due to radionuclides in detergent powders. The results indicate that the analyzed samples of detergent powders are safe for consumers and the environment.
Acoustic and perceptual cues to gender identification : a study of transsexual voice and speech characteristics
Creators: name: Wollitzer, Lisa Candice
Publisher: name: University of British Columbia

description: Few studies address the assessment and management of the voice and speech patterns of Male-to-Female Transsexuals (MTS). The clinician working with this population may therefore be faced with considerable difficulty in planning valid and effective intervention programmes. The purpose of this study was to investigate acoustic and perceptual-acoustic aspects of MTS voice to suggest the most effective and relevant therapy activities for this clinical population. Of particular interest was the anatomical-acoustic mismatch inherent in MTS speech. A further motivation was to investigate the relationship between salient acoustic variables associated with gender identification and their perceptual correlates. Where such relationships can be demonstrated, clinical practice may be simplified by targeting only the most salient features. Subjects were eleven Male-to-Female Transsexuals. Acoustic samples from an equal number of each of anatomical male and female speakers served as a reference. Multidimensional correlates characterizing female voice as distinct from male voice were identified. Social validation was used to determine how “successful” MTS speakers were in achieving a female voice. Results from the anatomical female and male speakers in combination with the information regarding the success of the MTS speakers were then used to suggest the most salient cues to feminine voice. Results suggest the FO average is the dominant characteristic in distinguishing male from female voice. Other distinguishing features include signal-to-noise ratio, Fl and the perceptual judgement of larynx height. Characteristics separating MTS speakers from both anatomical groups were the extent of FO shift relative to habitual speaker FO and antero-posterior tongue posture. Moderate to strong relationships for several pairs of acoustic and perceptual variables were found. The data suggest that speaker FO and pitch are not heavily constrained by physical characteristics of a speaker. For MTS speakers, this means that the individual’s ability to achieve a more feminine voice may not be restricted by an anatomically male vocal tract. Results of correlational analyses suggest that several acoustic variables may have influenced naive listener judgements of masculinity-femininity.

description: Online learning methods, like the online gradient algorithm (OGA) and exponentially weighted aggregation (EWA), often depend on tuning parameters that are difficult to set in practice. We consider an online meta-learning scenario, and we propose a meta-strategy to learn these parameters from past tasks. Our strategy is based on the minimization of a regret bound. It allows to learn the initialization and the step size in OGA with guarantees. It also allows to learn the prior or the learning rate in EWA. We provide a regret analysis of the strategy. It allows to identify settings where meta-learning indeed improves on learning each task in isolation.

description: The design of large libraries of oligonucleotides having constant GC-content and satisfying Hamming distance constraints between oligonucleotides and their Watson-Crick complements is important in reducing hybridization errors in DNA computing, DNA microarray technologies, and molecular bar coding. Various techniques have been studied for the construction of such oligonucleotide libraries, ranging from algorithmic constructions via stochastic local search to theoretical constructions via coding theory. We introduce a new stochastic local search method which yields improvements up to more than one third of the benchmark lower bounds of Gaborit and King (2005) for n-mer oligonucleotide libraries when n <= 14. We also found several optimal libraries by computing maximum cliques on certain graphs.

description: Μέχρι στιγμής δύο μέλη της οικογένειας των BMPs – οι BMP2 και BMP7 έχουν παραχθεί και λάβει έγκριση για τη θεραπεία καταγμάτων, ενώ βρίσκεται σε πειραματικό στάδιο η διερεύνηση της θεραπευτικής τους αξίας σε περιπτώσεις αναγέννησης χόνδρου. Εξαιτίας των χημικών και βιολογικών χαρακτηριστικών τους, συνήθως χορηγούνται σε συνδυασμό με ειδικούς φορείς (carriers) οι οποίοι προστατεύουν ή ακόμα και ενισχύουν την βιολογική τους δράση. Στην παρούσα εργασία η διαδικασία προσθήκης ενός μορίου βιοτίνης στο Ν-τελικο άκρο της ανθρώπινης πρωτεΐνης BMP2 είχε ως τελικό σκοπό την πρόσδεσή της τελευταίας σε νανοεπιφάνειες για εφαρμογές στο πεδίο της Μηχανικής των Ιστών (tissue engineering). Η βιοτίνη παρέχει ισχυρά πλεονεκτήματα που την καθιστούν ελκυστικό υποψήφιο για σήμανση των πρωτεϊνών. Καταρχάς το μικρό μοριακό της βάρος (MW = 244.31 da) δεν παρεμποδίζει τις χημικές και βιολογικές λειτουργίες των πρωτεϊνών και επιπλέον η βιοτίνη συνδέεται ισχυρά και μεγάλη επιλεκτικότητα με την στρεπταβιδίνη γεγονός που μας προσφέρει πολλά πλεονεκτήματα στον εντοπισμό αλλά και την προσκόλληση της βιοτινυλιωμένης πρωτεΐνης σε επιφάνειες με καλυμμένες με στρεπταβιδίνη.
description: Until now, two members of BMPs family- BMP2 and BMP7, have been produced and approved for bone fractions treatment, while their therapeutic potential in cartilage regeneration is under investigation. Because of their chemical and biological characteristics, they are usually treated in combination with specific carriers which protect or even enhance their biological activities.Ιn the present study, the process of adding a biotin molecule to the N- terminal of human BMP2 protein served the purpose of binding to nano –surfaces for tissue engineering applications. Biotin molecule, provides strong advantages which makes it an attractive candidate for protein labeling. At first, it’s small molecular weight (MW = 244.31 da) does not impede to chemical and biological functions of proteins. Besides that biotin binds with great strength and specificity with streptavidin which provides o lot of advantages in localization and attachment of the biotinylated protein to surfaces covered with streptavidin.
The Four Pathways to Counterfactuality
Creators: name: Fraser, Stewart
Publisher: name: Zenodo
Year: 2024
Subjects: Linguistics, Counterfactual, Irrealis, Past Tense, Grammaticalization, Grammaticization

description: In certain situations a past tense marker in conjunction with another word, gives a sentence a counterfactual meaning. For example “In present day English “if you competed tomorrow, you would win” implies that the competing (and the winning) will probably not take place. That is the past tense marker in conjunction with "if" gives an irrealis vibe to the sentence. Also the past tense meaning has been lost. 

There is a grammatical process behind this shift of meaning. I describe four "pathways" that have produced counterfactuality within the historical English period.

I contend that this process split "ought" from "owe" and "might" from "may" well over a thousand years ago. And more recently split "should" from "shall", "would" from "will" and "could" from "can". In present day English, in certain situations the first element is simply the past of the second element. But this is just a holdover from ancient times. All ten words listed here are definitely separate words.

You might has noticed that I mentioned "irrealis vibe" in the first paragraph. This is because the counterfactual (or irrealis, same thing) markers are never absolute, they are never 100% counterfactual. Indeed we have negation markers for that job (like "not" (usually along with "do") in English). I believe that all counterfactual markers have a valve of about "90% not going to happen" (AKA 90% counterfactual or 90% irrealis) when they first split off from the mother word. However over time, this percentage can vary, as indeed any part of the meaning can vary. 

One could say that counterfactual markers are the unintended detritus of an unplanned grammaticalization process. OK, but are they useful ? Mmmh, well they are used. So I guess you could say that they are useful. But we mustn't be so self-centred to think that all that exists in nature is put there to serve us.

description: Two super-integrable and super-separable classical systems which can be considered as deformations of the harmonic oscillator and the Smorodinsky-Winternitz in two dimensions are studied and identified with motions in spaces of constant curvature, the deformation parameter being related with the curvature. In this sense these systems are to be considered as a harmonic oscillator and a Smorodinsky-Winternitz system in such bi-dimensional spaces of constant curvature. The quantization of the first system will be carried out and it is shown that it is super-solvable in the sense that the Schrödinger equation reduces, in three different coordinate systems, to two separate equations involving only one degree of freedom.

description: Based on a spectral analysis of the X-ray continuum that employs a fully relativistic accretion-disk model, we conclude that the compact primary of the binary X-ray source GRS 1915+105 is a rapidly-rotating Kerr black hole. We find a lower limit on the dimensionless spin parameter of a* greater than 0.98. Our result is robust in the sense that it is independent of the details of the data analysis and insensitive to the uncertainties in the mass and distance of the black hole. Furthermore, our accretion-disk model includes an advanced treatment of spectral hardening. Our data selection relies on a rigorous and quantitative definition of the thermal state of black hole binaries, which we used to screen all of the available RXTE and ASCA data for the thermal state of GRS 1915+105. In addition, we focus on those data for which the accretion disk luminosity is less than 30% of the Eddington luminosity. We argue that these low-luminosity data are most appropriate for the thin alpha-disk model that we employ. We assume that there is zero torque at the inner edge of the disk, as is likely when the disk is thin, although we show that the presence of a significant torque does not affect our results. Our model and the model of the relativistic jets observed for this source constrain the distance and black hole mass and could thus be tested by determining a VLBA parallax distance and improving the measurement of the mass function. Finally, we comment on the significance of our results for relativistic-jet and core-collapse models, and for the detection of gravitational waves.
