A number of forensic techniques have been developed to identify the use of digital multimedia editing operations. In response, several anti-forensic operations have been designed to fool forensic algorithms. One operation that has received considerable attention is median filtering, since it can be used for image enhancement or anti-forensic purposes. As a(More)
INTRODUCTION Recent advances in the treatment of NSCLC highlight the importance of distinguishing NSCLC subtypes and genotypes. We aimed to determine whether histological specimens obtained from computed tomography (CT)-guided biopsy are suitable for specific subtyping and epidermal growth factor receptor (EGFR) analyses of NSCLC. PATIENTS AND METHODS The(More)
In an indoor environment, there commonly exist a large number of multipaths due to rich scatterers. These multipaths make the indoor positioning problem very challenging. The main reason is that most of the transmitted signals are significantly distorted by the multipaths before arriving at the receiver, which causes inaccuracies in the estimation of the(More)
INTRODUCTION Treatment with epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) has been associated with favorable progression free survival (PFS) in patients with non-small cell lung cancers (NSCLC) harboring EGFR mutations. However, a subset of this population doesn't respond to EGFR-TKI treatment. Therefore, the present study aimed(More)
The temperature evolution of icosahedral medium-range order formed by interpenetrating icosahedra in CuZr metallic glassforming liquids was investigated via molecular dynamics simulations. Scaling analysis based on percolation theory was employed, and it is found that the size distribution of clusters formed by the central atoms of icosahedra at various(More)
Driven by the demand for supporting the rapidly increasing wireless traffic, the next generation communication system, i.e. the 5G system, needs to accommodate a massive number of users and judiciously manage the interference. One promising candidate, the time reversal (TR) system, uses a large bandwidth and designs transmitting waveforms such that the(More)
Due to the time-varying nature of wireless channels and the Internet backbone traffic, it is a challenging task to maintain the quality of wireless multimedia streaming throughout the transmission. An effective solution is to adapt the codec setting based on the wireless channel condition or the Internet backbone state. In this chapter, we present three(More)
In many glass-forming liquids, fractional Stokes-Einstein relation (SER) is observed above the glass transition temperature. However, the origin of such phenomenon remains elusive. Using molecular dynamics simulations, we investigate the break- down of SER and the onset of fractional SER in a model of metallic glass-forming liquid. We find that SER breaks(More)
Multimedia data are sensitive to delay which deteriorates the video quality and the perception of the viewer. Due to the sensitivity to the delay, transmitting multimedia data over inherently variant wireless channels is a big challenge. Although wireless systems have employed adaptive modulation and coding (AMC) to combat the variation of the environment,(More)
Next-generation wireless networks are expected to support exponentially increasing number of users and demands of data, which all rely on the essential media: spectrum. Notice that the 5G networks are featured either by wide bandwidth like mmWave systems, or by large-scale antennas like massive MIMO. We find those two trends, together with waveforming or(More)
