Tamoxifen (TAM) is the most widely used endocrine therapy for estrogen receptor (ER)-positive breast cancer patients, but side effects and the gradual development of insensitivity limit its application. We investigated whether Huaier extract, a traditional Chinese medicine, in combination with TAM would improve treatment efficacy in ER-positive breast cancers. MTT, colony formation, and invasio...

This article describes a fair and robust video streaming framework over IP networks. It is based on an MPEG4 Audio-Visual Object (AVOs) classification, TCP-Friendly transport and out-of-band unequal forward error protection. According to network congestion feedback, video source servers dynamically adjust their bit rates by adding and dropping MPEG-4 AVO to conform to the TCP-Friendly Rate Cont...

Low velocity noise can contaminate reflections and distort AVO amplitude information. I explore different inversion methods for suppressing low velocity noise while simultaneously preserving amplitudes along reflections. A velocity-stack inversion process is used for recreating models in velocity space that can reconstruct the reflections and the low velocity noise. Velocity-stack inversion is ...

Prestack migration is necessary before AVO analysis. Most of the present migration algorithms not only try to focus the reflections on the subsurface but also strive to preserve the amplitude for subsequent amplitude studies. A migration/inversion method developed by Lumley (1993) estimates the angle dependent reflectivity at each subsurface point by using least-squares Kirchhoff migration foll...

Abstract Most frequency-dependent AVO inversions are currently based on an approximate equation derived using isotropic medium. However, actual reservoirs usually show anisotropy, such as shale reservoirs, tight sandstone and fractured reservoirs. We propose a joint (JFAVO) inversion in anisotropic medium periodic layered double-porosity This JFAVO will allow us to quantitatively study the infl...

Subjective decision making can lead to errors in supplier selection. In the selection of suppliers, OEM (Original Equipment Manufacturing) Department has difficulty choosing because many suppliers have submitted offers cooperation. Therefore, we need a support system so that department determine appropriate purchasing products, services and materials. This uses SAW (Simple Additive Weighting) m...

A novel inter-disciplinary methodology for the generation of rock property and AVO feasibility maps or cubes to be used in subsurface characterization prospect de-risking is presented. We demonstrate workflow 1D, 2D 3D cases on data from North Sea Barents Sea, offshore Norway. The enables rapid extrapolation expected physics properties away well control along selected horizons, constrained by s...

For laterally complex media, it may be more suitable to take a different orientation of thedisplacement vector of Shear-waves. This may change the sign of several imaginary reflections andconversion coefficients to be used in reservoir characterization and AVO (Amplitude Versus Offset)analysis or modeling. In this new convention the positive direction of the displacement vector ofreflected Shea...
