description: We present a three dimensional radiative transfer model to examine the effects of resonance line scattering in the post-shock flow behind a non-radiative supernova remnant shock. For a rippled shock front viewed edge-on, line scattering significantly reduces the observed flux of CIV 1549 and NV 1240, two important diagnostic lines in the ultraviolet spectra of supernova remnants. The correction factor (defined to be the ratio of the line flux that would be observed neglecting scattering, to the actual observed line flux) is a function of position within the filament. For sufficiently large regions that include crisp edges as well as more diffuse regions of the filament structure, the CIV and NV correction factors are between about 1.5 and 3.5 (and the CIV correction factor is invariably larger than the NV correction factor). The correction factors have a larger range when smaller regions are considered. The CIV correction factor is about 6 at the filament edges, while the NV correction factor is about 4. These simulations of resonance line scattering will be useful for the analysis of supernova remnant shock spectra.

description: Diagnosing epilepsy requires accurate seizure detection and classification, but traditional manual EEG signal analysis is resource-intensive. Meanwhile, automated algorithms often overlook EEG's geometric and semantic properties critical for interpreting brain activity. This paper introduces NeuroGNN, a dynamic Graph Neural Network (GNN) framework that captures the dynamic interplay between the EEG electrode locations and the semantics of their corresponding brain regions. The specific brain region where an electrode is placed critically shapes the nature of captured EEG signals. Each brain region governs distinct cognitive functions, emotions, and sensory processing, influencing both the semantic and spatial relationships within the EEG data. Understanding and modeling these intricate brain relationships are essential for accurate and meaningful insights into brain activity. This is precisely where the proposed NeuroGNN framework excels by dynamically constructing a graph that encapsulates these evolving spatial, temporal, semantic, and taxonomic correlations to improve precision in seizure detection and classification. Our extensive experiments with real-world data demonstrate that NeuroGNN significantly outperforms existing state-of-the-art models.

description:
Arab Americans constitute a diverse, sizeable ethnic minority in the United States. However, limited research has examined the content of Arab American ethnic identity and whether this ethnic identity differs by demographic factors. In the present study, we developed measures of Arab American ethnic identity and cultural practice, and assessed differences in those variables by gender, religious affiliation (Muslim, Christian), and age. Arab American adults recruited online from Amazon Mechanical Turk (N = 391) completed an adaptation of the Multidimensional Inventory of Black Identity and a measure of cultural practice that was created for this study based on pre-existing scales. Items loaded onto dimensions of identity (ethnic centrality, private regard, public regard), and subscales showed invariance across gender and religious upbringing. When examining group differences in ethnic identity, we found that attitudes regarding being Arab American varied by gender, such that Arab American women reported higher private regard and lower public regard than men. In turn, participants raised in Muslim households reported higher ethnic centrality and cultural practice than those raised in Christian households, potentially related to Muslims' status as a religious minority in the United Status. Finally, young adults were lower in centrality and private regard than older adults, suggesting either that ethnic identity may develop into adulthood or that young adults' ethnic identity may be influenced by growing up in American society post-9/11. Taken together, findings illustrate the heterogeneity in the ethnic identity of Arab Americans; further research is needed to understand individual differences in Arab Americans' ethnic identity.

description: The existence of quasi-long range order is demonstrated in nonequilibrium steady states in isotropic $XY$ spin chains including of two types of additional terms that each generate a gap in the energy spectrum. The system is driven out of equilibrium by initializing a domain-wall magnetization profile through application of an external magnetic field and switching off the magnetic field at the same time the energy gap is activated. An energy gap is produced by either applying a staggered magnetic field in the $z$ direction or introducing a modulation to the $XY$ coupling. The magnetization, spin current, and spin-spin correlation functions are computed analytically in the thermodynamic limit at long times after the quench. For both types of systems, we find the persistence of power-law correlations despite the ground-state correlation functions exhibiting exponential decay.

The Mass of the Milky Way: Limits from a Newly Assembled Set of Halo Objects

description: We set new limits on the mass of the Milky Way, making use of the latest kinematic information for Galactic satellites and halo objects. In order to bind these sample objects to the Galaxy, their rest-frame velocities must be lower than their escape velocities at their estimated distances. This constraint enables us to show that the mass estimate of the Galaxy is largely affected by several high-velocity objects (Leo I, Pal 3, Draco, and a few FHB stars), not by a single object alone (such as Leo I), as has often been the case in past analyses. We also find that a gravitational potential that gives rise to a declining rotation curve is insufficient to bind many of our sample objects to the Galaxy; a possible lower limit on the mass of the Galaxy is about 2.2 x 10^12 Msolar. To be more quantitative, we adopt a Bayesian likelihood approach to reproduce the observed distribution of the current positions and motions of the sample, in a prescribed Galactic potential that yields a flat rotation curve. This method enables a search for the most likely total mass of the Galaxy, without undue influence in the final result arising from the presence or absence of Leo I, provided that both radial velocities and proper motions are used. The most likely total mass derived from this method is 2.5^+0.5_-1.0 x 10^12 Msolar (including Leo I), and 1.8^+0.4_-0.7 x 10^12 Msolar (excluding Leo I).

description: In this communication we present a method of complete basis set (CBS) extrapolation of correlation energies obtained with a systematic sequence of one-electron basis sets. Instead of fitting the finite-basis results with a certain functional form, we perform analytic re-summation of the missing contributions coming from higher angular momenta, $l$. The assumption that they vanish asymptotically as an inverse power of $l$ leads to an expression for the CBS limit given in terms of the Riemann zeta function. This result is turned into an extrapolation method that is very easy to use and requires no "empirical" parameters to be optimized. The performance of the proposed method is assessed by comparing the results with accurate reference data obtained with explicitly correlated theories and with results obtained with standard extrapolation schemes. On average, the errors of the zeta-function extrapolation are several times smaller compared with the conventional schemes employing the same number of points. A recipe for estimation of the residual extrapolation error is also proposed.

description: Electron-positron pair production from vacuum in a strong electric field oscillating in time is studied. The field is assumed to consist of two consecutive pulses, with variable time delay in between. Pair production probabilities are obtained by numerical solution of the corresponding time-dependent Dirac equation. Considering symmetric field configurations comprising two identical pulses, we show that the pulse distance strongly affects the momentum spectra of produced particles and even the total production probability. Conversely, in a highly asymmetric situation when the field contains low-intensity prepulse and high-intensity main pulse, we identify a range of field parameters where the prepulse despite its weakness can leave visible traces in the particle spectra.

description: The growing size of modern data sets brings many challenges to the existing statistical estimation approaches, which calls for new distributed methodologies. This paper studies distributed estimation for a fundamental statistical machine learning problem, principal component analysis (PCA). Despite the massive literature on top eigenvector estimation, much less is presented for the top-L-dim (L > 1) eigenspace estimation, especially in a distributed manner. We propose a novel multi-round algorithm for constructing top-L-dim eigenspace for distributed data. Our algorithm takes advantage of shift-and-invert preconditioning and convex optimization. Our estimator is communication-efficient and achieves a fast convergence rate. In contrast to the existing divide-and-conquer algorithm, our approach has no restriction on the number of machines. Theoretically, the traditional Davis-Kahan theorem requires the explicit eigengap assumption to estimate the top-L-dim eigenspace. To abandon this eigengap assumption, we consider a new route in our analysis: instead of exactly identifying the top-L-dim eigenspace, we show that our estimator is able to cover the targeted top-L-dim population eigenspace. Our distributed algorithm can be applied to a wide range of statistical problems based on PCA, such as principal component regression and single index model. Finally, We provide simulation studies to demonstrate the performance of the proposed distributed estimator.

description: High-tech communication aids are one form of augmentative and alternative communication (AAC) intervention offered to children following an assessment process to identify the most appropriate system based on their needs. Professional recommendations are likely to include consideration of child characteristics and communication aid attributes. Recommendations may be influenced by contextual factors related to the cultural work practices and service context of professionals involved, as well as by contextual factors from the child’s life including their family environment and wider settings. The aim of this study was to explore the influence of cultural and contextual factors on the real-time decision-making processes of specialized AAC professionals in the UK. A total of six teams were recruited to the study. Each team carried out an assessment appointment related to a communication aid recommendation for a child and family. Following the appointment, each team participated in a focus group examining their decision-making processes during the preceding assessment. Inductive coding was used to analyse the transcribed data, and three organizing themes emerged relating to the global theme of Cultural and Contextual Influencers on communication aid decision-making. An explanatory model was developed to illustrate the funnelling effect that contextual factors may have on decision-making, which can substantially alter the nature and timing of a communication aid recommendation. Implications for clinical practice and future research are discussed.

description: Recent work applying multidimentional coherent electronic spectroscopy at dilute samples in the gas phase is reviewed. The development of refined phase-cycling approaches with improved sensitivity has opened-up new opportunities to probe even dilute gas-phase samples. In this context, first results of 2-dimensional spectroscopy performed at doped helium droplets reveal the femtosecond dynamics upon electronic excitation of cold, weakly-bound molecules, and even the induced dynamics from the interaction with the helium environment. Such experiments, offering well-defined conditions at low temperatures, are potentially enabling the isolation of fundamental processes in the excitation and charge transfer dynamics of molecular structures which so far have been masked in complex bulk environments.

description: We consider mixed quasi-free states describing $N$ fermions in the mean-field limit. In this regime, the time evolution is governed by the nonlinear Hartree equation. In the large $N$ limit, we study the convergence towards the classical Vlasov equation. Under integrability and regularity assumptions on the initial state, we prove strong convergence in trace and Hilbert-Schmidt norm and provide explicit bounds on the convergence rate for a class of singular potentials of the form $V(x)=|x|^{-α}$, for $α\in(0,1/2)$.

description: We report and interpret HST/STIS long-slit observations of the optical and ultraviolet (1150 - 10270 Angstrom) emission-line spectra of the rapidly brightening Spot 1 on the equatorial ring of SN 1987A between 1997 September and 1999 October (days 3869 -- 4606 after outburst). The emission is caused by radiative shocks created where the supernova blast wave strikes dense gas protruding inward from the equatorial ring. We measure and tabulate line identifications, fluxes and, in some cases, line widths and shifts. We compute flux correction factors to account for substantial interstellar line absorption of several emission lines. Nebular analysis shows that optical emission lines come from a region of cool (T_e ~ 10^4 K) and dense (n_e ~ 10^6 cm^-3) gas in the compressed photoionized layer behind the radiative shock. The observed line widths indicate that only shocks with shock velocities V_s < 250 km/s have become radiative, while line ratios indicate that much of the emission must have come from yet slower (V_s < 135 k/ms) shocks. We are able to fit the UV fluxes with an idealized radiative shock model consisting of two shocks (V_s = 135 and 250 km/s). The observed UV flux increase with time can be explained by the increase in shock surface areas as the blast wave overtakes more of the protrusion. The observed flux ratios of optical to highly-ionized UV lines are greater by a factor of ~ 2 -- 3 than predictions from the radiative shock models and we discuss the possible causes. We also present models for the observed H-alpha line widths and profiles, which suggests that a chaotic flow exists in the photoionized regions of these shocks. We discuss what can be learned with future observations of all the spots present on the equatorial ring.

description: Software production research is quickly evolving on two parallel approaches: conventional and bio-inspired. The bio-inspired approaches are generally developed and presented as enhancements of the conventional ones. However the conventional approaches benefit from their integration with their global context, through software engineering methodologies, for being advantageous.The integration of bio-inspired approaches with bio-inspired software engineering methodologies will enrich them and let them be irrefutably be the best. This paper identify the motivations to the emergence of such bio-inspired software engineering, presents a first approach to it, with a road map, and some of its challenges.The application of this first approach on different software systems categories is presented with its summary evaluation. However, the evaluation on industrial scale remains a challenge.

description: Indonesia is one of the countries in Southeast Asia where malaria is a prominent public health concern with an estimated 15 million malaria cases annually and 42,000 deaths. The study explores the environmental risk factors of malaria guided by an eco epidemiological model of malaria transmission. A longitudinal and cross sectional approach has been employed for data gathering of the environmental variables, spatial and temporal patterns of malaria transmission, malaria vectors behaviour and human risk factors of malaria transmission in Indonesia. Three different regions in Indonesia were used for the study. The first area is West Timor which has the highest malaria incidence in Indonesia. The second location is Sukabumi District of West Java, which had a malaria outbreak in 2003. The final location is Kebumen District of Central Java, which has one of the highest malaria pocket areas in Java. All areas were divided into three different topographical settings - coastal, hilly and highland areas. In each study areas, the environmental data were analysed using t-test, ANOVA, Pearson Correlation, and General Linear Model Repeated Measures. Further, LISA (Local Indicators of Spatial Association) analysis using GIS was employed to explore local malaria spatial distribution and generate malaria maps for the malaria transmission areas based on the local spatial association. Adult mosquito (Anopheles spp) surveys were used to explore malaria vectors behaviour in different areas and different topographical settings. Finally, an interview program was used to collect data in order to understand human risk factors in malaria transmission. [...]

description: We report the second study from the FUSE survey of molecular hydrogen in translucent clouds, for the line of sight toward HD 110432. This star lies beyond the Coalsack dark nebula, and with E(B-V) = 0.40, and A_V = 1.32 this line of sight bridges the gap between less extinguished diffuse cloud lines of sight with A_V \sim 1, such as Zeta Oph, and the translucent clouds with A_V \gtrsim 2 such as HD 73882. Through profile fitting and a curve-of-growth analysis, we have derived rotational populations for H2 for J = 0--7. The line of sight has a total molecular hydrogen column density, log N(H2) = 20.68 \pm 0.05 cm^{-2}, nearly identical to that toward Zeta Oph, but a factor of three less than HD 73882. The ratio of N(J=1) to N(J=0) yields a kinetic temperature T_{kin} = 63 \pm 7 K, similar to other lines of sight with A_V \gtrsim 1. The high-J lines show considerable excitation above this temperature. The high-J excitation is similar to that toward Zeta Oph, but much smaller than that toward HD 73882. Chemical modeling indicates that the physical conditions in the cloud(s) are very similar to those in the cloud(s) toward Zeta Oph. An analysis of IUE spectra of the Lyman-alpha line gives log N(H I) = 20.85 \pm 0.15 cm^{-2}. Combined with N(H2), we derive a hydrogen molecular fraction, f_{H2} = 0.58 pm 0.12, statistically identical to that found for the lines of sight toward Zeta Oph and HD 73882. We also report column densities for the HD and CO molecules. From the combined measurements of hydrogen and carbon- containing molecules, the line of sight toward HD 110432 appears quite similar to the diffuse cloud line of sight toward Zeta Oph, and quite dissimilar to the translucent cloud line of sight toward HD 73882.

description: Introduction: Treosulfan is an alkylating agent that is used for the treatment of ovarian cancer and for conditioning prior to stem cell transplantation. It is a prodrug that is activated non-enzymatically to two active epoxides. Objectives: To optimize a protocol for both in vivo samples handling and in vitro drug preparation. Treosulfan stability was tested in biological fluids at different conditions as well as for its cytotoxicity on cell lines. Results: Plasma samples can be safely frozen for a short period up to 8 h, however; for longer periods, samples should be acidified. Urine samples and cell culture media can be safely frozen regardless their pH. For in vitro investigations, incubation of treosulfan at 37 °C for 24 h activated 100% of the drug. Whole blood acidification should be avoided for the risk of hemolysis. Finally; treosulfan cytotoxicity on HL-60 cells has increased following pre-incubation for 24 h at 37 °C compared to K562 cell line. Conclusion: The stability profiling of treosulfan provided a valuable reference for handling of biological samples for both in vivo and in vitro studies. These results can be utilized for further investigations concerning the drug kinetics and dynamics in addition to the development of new pharmaceutical formulations.

The development of a numerical code for MHD simulation using the GPM algorithm is outlined. Validation tests simulating linear and nonlinear sound waves, linear MHD waves, advection of magnetic fields in a magnetized vortex, hydrodynamical shocks, and three-dimensional collapse are presented, demonstrating the viability of an MHD code using GPM. The characteristics of a GPM code are discussed and possible avenues for further development and refinement are mentioned. We conclude with a view of how GPM may complement other methods currently in development for the next generation of computational astrophysics.

description: The light-cone gauge approach to $T{\overline T}$ deformed models is generalised to models deformed by U(1) conserved currents $J^α$, $\widetilde J^α$, stress-energy tensor $T^α_β$, and their various quadratic combinations of the form $ε_{αβ} K_1^αK_2^β$. It is then applied to derive a ten-parameter deformed Hamiltonian for a system of scalars with an arbitrary potential, the flow equations for the Hamiltonian density, and the flow equations for the energy of the deformed model. The flow equations disagree with the ones recently proposed in arXiv:1903.07606. The results obtained are applied to analyse a CFT with left- and right-moving conserved currents deformed by these operators. It is shown that with a proper choice of the parameter of the $T{\overline T}$ deformation the deformed CFT Hamiltonian density is independent of the parameters of the $JΘ$ and $\bar J\overline Θ$ deformations. This leads to the existence of two extra relations which generalise the $JΘ=0$ and $\bar J\overline Θ=0$ relations of the undeformed CFT. The spectrum of the deformed CFT is found and shown to satisfy the flow equations.

description: Excerpts from the report Introduction: Pyrethrum mists and aerosols have been used extensively in tobacco warehouses and factories to control the tobacco moth and the cigarette beetle. They are highly effective against the moth, but much less so against the beetle. A pyrethrum mist, originally called a "space spray," was developed to control the tobacco moth in open-type storage warehouses. It did this most efficiently. Later, an effort was made to adapt this treatment to control the cigarette beetle in all types of warehouses and factories. This was much less successful. Many misconceptions have arisen as to what can be expected of mists and aerosols. This method of applying insecticides has certain inherent limitations. The object of this paper is to explain how, where, and why pyrethrum treatments are effective, and where and why they may not be effective.
title: Atomic Bomb Blues: Myth and Melancholy in American Science Fiction Film of the 1950s
Creators: name: Williamson, James Bruce
Publisher: name: Goldsmiths, University of London
Year: 2022

description: Through a series of close readings of six Hollywood science fiction films of the 1950s, this thesis investigates the genre’s representation and rendering of social and political concerns specific to the historic moment through its repurposing and reimagining of mythic and archetypal narrative structures, conceptualised here as a corresponding phenomenon to the growth of interest in those areas of study within the academic community, for instance in the work of Campbell, Jung, and Frye. It establishes how this relationship is articulated in the form of a particular melancholic tone and attitude that contrasts with the ostensible stability and triumphalism of both the genre and American culture in this period, a melancholy that is apparent in the contemporary commentary of I.F. Stone and in the cybernetic theorising of Norbert Wiener. With an inductive method that connects formal and structural readings, grounded in a consideration of cinematic language and generic conventions, I address these recurring thematic concerns of the contemporary cultural and intellectual milieu that are also apparent in this selection of films. The thesis thus identifies direct adaptations of, and homologies with, prominent constellations of academic and popular thought in America at this time as they emerge through the corpus, and thereby argues for the value of such comparative analysis. The readings therefore address such phenomena as the popularity of Freudian psychology, the development of cybernetics, and the evolution of structural thought, identifying a clear bridge between these immediate historic and cultural concerns, and the functioning of the science fiction genre in cinema at this point in its own evolution. In so doing, it also lays the groundwork for a new history of science fiction film, suggesting a triangulation of the genre’s relationship with parallel social, cultural, and political trends through consideration of the mythic and the melancholic.

description: We study the evolution of elliptical galaxies at z >~ 1 on the basis of a sample of 247 Extremely Red Objects (EROs) with R-Ks >= 3.35 (AB) and Ks <= 22.1 (AB) constructed from BVRi'z'JHKs multicolor data of a 114 arcmin2 area in the Subaru/XMM Deep Survey Field. By fitting template spectra of old ellipticals (OEs) and young, dusty starbursts (DSs) to the multicolor data, we classify EROs into these two classes and estimate their redshifts. We find that 58% of the EROs in our sample belong to the OE class and that 24% of the OEs are fit by a spectrum having a disk component with the B-band bulge-to-total luminosity ratio of <= 0.9. We compare the observed surface density of OEs with predictions from passive evolution models. We then derive rest-frame B-band luminosity functions (LFs) of OEs in our sample at z=1-1.5 and 1.5-2.5. We find that the LF at z=1-1.5 roughly agrees with the LF of local ellipticals if a dimming of 1.3 mag from z=1.25 to the present epoch is assumed. On the other hand, the amplitude of the LF at z=1.5-2.5 is found to be lower than that of the local LF by a factor of ~ 3 over the whole range of magnitude observed. Taking account of a strong decrease in the number density of morphologically classified early-type galaxies at z >~ 1.5 found by several authors, we conclude that the majority of ellipticals seen at present have not established either a red color or a smooth 1/4-law profile before z ~ 1.5$.

Dynamics of Relativistic Magnetized Blast Waves

description: The dynamics of a relativistic blast wave propagating through magnetized medium is considered taking into account possible inhomogeneities of density and magnetic field and additional energy supply. Under the simplifying assumption of a spherically symmetric explosion in a medium with toroidal magnetic field self-similar solutions for the internal dynamics of the flow are derived. In the weakly magnetized case, when the bulk of the flow may be described by the unmagnetized solutions, there is a strongly magnetized sheath near the contact discontinuity (when it exists). Self-similar solutions inside the sheath are investigated. In the opposite limit of strongly magnetized upstream plasma new analytical self-similar solutions are found. Possible application to the physics of Gamma-Ray Bursts is discussed.

description: Excerpts from the report Introduction: Institutional grocery wholesaling is a function of food distribution in which carload and truckload shipments of food and related products are procured from packers, manufacturers, and other suppliers, moved into a warehouse, stored, and then sold and delivered to food service institutions. These operations require a vast amount of physical handling, coordination of wholesaling and food service functions, and detailed record keeping. Among the types of food service customers supplied by institutional grocery wholesalers are airline caterers, amusement park concessionaires, ball parks, cafeterias, caterers, dairy bars, drive-ins, governmental institutions and establishments, hospitals, hotels, in-plant feeding establishments, motels, public and private clubs, restaurants, river boats, schools, soda fountains, and summer camps. These customers vary in size from multimillion dollar operations to annual sales volumes of less than a thousand dollars. Services such as personal sales calls, delivery, and supplier credit are usually extended to food service customers. The primary objectives of this study were: (1) To define the operating policies and practices of some successful institutional wholesalers; and (2) to ascertain what services wholesalers are extending to customers to help them operate more efficiently and effectively.

description: Neutrino event generators are an essential tool needed for the extraction of neutrino mixing parameters, the mass hierarchy and a CP violating phase from long-baseline experiments. In this article I first describe the theoretical basis and the approximations needed to get to present-days generators. I also discuss the strengths and limitations of theoretical models used to describe semi-inclusive neutrino-nucleus reactions. I then confront present day's generators with this theoretical basis by detailed discussions of the various reaction processes. Finally, as examples I then show for various experiments results of the generator GiBUU for lepton semi-inclusive cross sections as well as particle spectra. I also discuss features of these cross sections in terms of the various reaction components, with predictions for DUNE. Finally, I argue for the need for a new neutrino generator that respects our present-day knowledge of both nuclear theory and nuclear reactions and is as much state-of-the-art as the experimental equipment. I outline some necessary requirements for such a new generator.

description: Excerpts from the report Introduction: Transportation of fresh vegetables to ships stationed in foreign waters and to overseas bases is often a major problem for the officers and crew of a U. S. Navy supply ship. Maintenance of the original quality is difficult when the vegetables must be carried aboard the ship for a month or longer. In addition, waste is sometimes considerable during the long transit and storage periods before the vegetables are consumed. Any improved methods of handling or packaging which would lengthen the storage life or maintain the original quality and reduce the amount of waste of fresh vegetables during transit would be of considerable value. Studies were begun in 1954 at the U. S. Department of Agriculture's Plant Industry Station at Beltsville, Md., to investigate various new handling and packaging methods for prolonging storage life and maintaining quality of fresh vegetables. Supply ship conditions were simulated for these studies. Later, in the spring of 1958, a test shipment was made which used much of the information gained from the laboratory research. The test was conducted aboard the USS Rigel, a supply ship assigned to the Sixth Fleet, operating in the Mediterranean. This report is a summary of the results of that test.

description: Sugar-sweetened beverage (SSB) taxes have been implemented by various regions across the world and previous studies have demonstrated their effect of lowering SSB consumption. The current study taps into a unique SSB tax situation in Cook County, Illinois. By analyzing around 2,000 households located in Cook County and its adjacent counties using fixed effects and difference-in-differences estimation, the current research indicated an approximately 30% drop in SSB consumption after the tax went into effect and a full recovery in consumption after the tax was officially repealed.

description: We report on low-resolution spectroscopy of GX339-4 during its current, extended X-ray `off' state in May 2000 (r=20.1) obtained with the VLT Focal Reducer/low dispersion Spectrograph (FORS1). Although we do not positively detect the secondary star in GX339-4 we place an upper limit of 30 percent on the contribution of a ``normal'' K-type secondary star spectrum to the observed flux. Using this limit for the observed magnitude of the secondary star, we find a lower limit for the distance of GX339-4 to be 5.6 kpc.
