Introduction: According to the American Society of Radiation Oncology, all patients receive radiation therapy during their illness, where radiation is delivered by the medical linear accelerator (Linac). The aim of this study was to evaluate the quality assurance (QA) of the Linac in analyzing the used dose profile in the treatment of cancer tumors. Materi...

We present the results of a combined investigation of the spectral and kHz QPO evolution around the Z-track in GX5-1 based on high-quality Rossi-XTE data. In spectral analysis, we find that the Extended ADC emission model provides very good fits to all of the spectra, and the results point clearly to a model for the nature of the Z-track in this source, in agreement with previous results for th...

We present the design and performance analysis of a new integrated track reconstruction code developed for the STAR experiment at RHIC. The code is meant to replace multiple previous tracker codes written in FORTRAN many years ago, and to readily enable integration of new and varied detector components. The new tracker is written from the ground up in C++ using a strong object -oriented model. ...

MOTIVATION Easily visualization of complex data features is a necessary step to conduct studies on next-generation sequencing (NGS) data. We developed STAR, an integrated web application that enables online management, visualization and track-based analysis of NGS data. RESULTS STAR is a multilayer web service system. On the client side, STAR leverages JavaScript, HTML5 Canvas and asynchronou...

STAR [1] is an active collider heavy-ion experiment at RHIC/BNL (Upton, USA). The main tracking detector of the experiment is the Time Projection Chamber (TPC). Due to the collision rate increasing (up to 40 KHz for Au+Au 200 GeV/n and up to 1 MHz for pp 500 GeV) and recording rate (up to 10 KHz) the STAR experiment requires a fast track reconstruction procedure which can deal with high track d...

We present results of a detailed study of X-ray flaring in the Z-track source Sco X-1 in a highly superEddington state made using high quality Rossi-XTE data from the PCA and HEXTE instruments. The emission model successfully used to explain the dipping LMXB, and other classes of LMXB in recent years, was applied to study the physical evolution along the Z-track which remains a major problem. T...

We complement our study of α/Fe enhanced stellar population models of Lick absorption indices (Thomas et al., 2003) by comparing two sets of α/Fe enhanced models. In both models the impact on Lick indices due to α/Fe enhancement is accounted for through a modification of the stellar absorption line-strengths using the response functions of Tripicco & Bell (1995). One set of models, however, use...

current practices in railway track analysis and design are reviewed and discussed in this paper. the mechanical behavior of railway track structure comprising of various components has not been fully understood due to the railway track structural complexity. although there have been some improvements in the accuracy of current track design methods in recent decades, there are still considerable...
