Spectroscopic observations of the fast X-ray transient and superluminal jet source SAX J1819.3-2525 (V4641 Sgr) reveal a best fitting period of Pspect = 2:81678 0:00056 days and a semiamplitude of K2 = 211:0 3:1 km s−1. The optical mass function is f (M) = 2:74 0:12 M . We find a photometric period of Pphoto = 2:81730 0:00001 days using a light curve measured from photographic plates. The folde...
We report on the rapid X-ray variability of the variable star and X-ray transient GM Sgr (SAX J1819.3–2525; XTE J1819–254) as observed on 15 Sept. 1999 by the proportional counter array (PCA) on board the Rossi X-ray Timing Explorer (RXTE). During the first ∼900 seconds of the first RXTE/PCA observation, GM Sgr showed very strong Xray fluctuations by a factor of 4 on time scales of seconds to a...
Abstract In this paper, we study the problem of finding solution system monotone variational inclusion problems recently introduced by Chang et al. (Optimization 70(12):2511–2525, 2020) with constraint a fixed-point set quasipseudocontractive mappings. We propose new iterative method that employs an inertial technique self-adaptive step size for approximating in Hilbert spaces and prove strong-...
the extent to which written corrective feedback on linguistic errors can play a role in helping l2 writers improve the accuracy of their writing continues to be an issue of interest to researchers and teachers since truscott (1996) mounted a case for its abolition. while there is growing empirical evidence that written corrective feedback can successfully target some types of linguistic error (...
the investigation would certainly offer implications for translation, where the translators mostly adhere to only the ideational meaning of the sl text neglecting its textual meaning, a practice which mostly leads to target language texts which have lower readability(compared with their source language counterparts) due to their displaced thematization strategies.
The Effects of the Shape and Size of the Clinical Target Volume on the Planning Target Volume Margin
PURPOSE To investigate the impact of clinical target volume (CTV) shape and size on CTV to planning target volume (PTV) margin expansion. METHODS AND MATERIALS Using numerical integration methods, margins accounting for random errors and systematic errors were calculated for CTVs of different shapes and sizes. We use k(r-95) and k(s-95) to represent the coefficients, for random errors and sys...
