BACKGROUND Radiofrequency ablation (RFA) is effective for treating Barrett's esophagus (BE) but often involves multiple endoscopy sessions over several months to achieve complete response. OBJECTIVE Identify structural markers that correlate with treatment response by using 3-dimensional (3-D) optical coherence tomography (OCT; 3-D OCT). DESIGN(More)
—We study the problem of optimally adapting ongoing cloud gaming sessions to maximize the gamer experience in dynamic environments. The considered problem is quite challenging because: (i) gamer experience is subjective and hard to quantify, (ii) the existing open-source cloud gaming platform does not support dynamic reconfigurations of video codecs, and(More)
Blind compressive sensing (CS) is considered for reconstruction of hyperspectral data imaged by a coded aperture camera. The measurements are manifested as a superposition of the coded wavelength-dependent data, with the ambient three-dimensional hyperspectral datacube mapped to a two-dimensional measurement. The hyperspectral datacube is recovered using a(More)
Three-dimensional (3D) tissue imaging methods are expected to improve surgical management of cancer. In this study, we examined the feasibility of two 3D imaging technologies, optical coherence tomography (OCT) and optical coherence microscopy (OCM), to view human breast specimens based on intrinsic optical contrast. Specifically, we imaged 44 ex vivo(More)
The rapid increase of biomedical literature available on the web has made it increasingly difficult to find precise information. To implement an accurate biomedical information retrieval (IR) system, we must deal with the variants of biomedical terms carefully. In this paper, we focus on the generation of aliases, synonyms, acronyms, and lexical variants of(More)
A new design of Psycho-Acoustic Model in MPEG-214 AAC encoding is proposed. Differing from the conventional PC-based and DSP-based encoders, it was based on hybrid architectures. It was optimized at algorithmic and at architectural levels. At algorithmic level, MDCT-based PAM and fixed-coefficients were used to replace the original FFPbased PAM and(More)
—Generally, the Log-MAP kernel of the turbo decoding consume large memories in hardware implement-tation. In this paper, we propose a new Log-MAP kernel to reduce memory usage. The comparison result shows our proposed architecture can reduce the memory size to 26% of the classical architecture. We also simplify the memory data access in this kernel design(More)
—The paper presents a new low complexity design of Psycho-Acoustic Model (PAM), which is the key technology for MPEG-2/4 Advanced Audio Coding (AAC) encoding. The real-time constraint of MPEG AAC leads to a heavy computational bottleneck on today's portable devices. To overcome this problem, design analysis and optimization of PAM are addressed at the(More)
