This paper introduces a next generation software-based GPS receiver technology that is capable of providing meters level accuracy, independent raw measurements and PVT (position, velocity, time) solutions using as little as 1-2ms (millisecond) of I/Q samples. This unprecedented performance is based on a revolutionary patent pending technology called Deep-RTM. Unlike conventional software based ...

BACKGROUND Medical researchers often use longitudinal observational studies to examine how risk factors predict change in health over time. Selective attrition and inappropriate modeling of regression toward the mean (RTM) are two potential sources of bias in such studies. METHOD The current study used Monte Carlo simulations to examine bias related to selective attrition and inappropriate mo...

Abstract Full-waveform inversion (FWI) of limited-offset marine seismic data is a challenging task due to the lack refracted energy and diving waves from shallow sediments, which are fundamentally required update long-wavelength background velocity model in tomographic fashion. When these events absent, reliable initial necessary ensure that observed simulated waveforms kinematically fit within...

Abstract The data-domain least-squares reverse time migration (LSRTM), a promising imaging method for obtaining high-resolution reflectivity image, can be implemented by matching the de-migrated data to observed one. However, LSRTM requires expensive computational costs in its implementation due tremendous memory usage (direct storage on disk/memory) saving source wavefields and repeatable forw...

The potential for real-time PCR (RTm-PCR) detection of the genetically engineered strain Pseudomonas putida GN2 was studied during 2-chlorobenzoate (2-CB) degradation in three different soils. The strain contained the constructed plasmid pGN2 which encoded genes for 2-CB oxidation (cbdA) and the green fluorescent protein (gfp). P. putida GN2 numbers were assessed by plating onto 2-CB minimal me...

In this paper we propose Re-Transport Media (RTM), a peer-to-peer streaming architecture which amortizes the bandwidth costs of serving internet media by cooperatively distributing the streaming load among connected clients. Conventional media streaming architectures typically impose significant bandwidth load on the server’s Internet uplink, requiring the content provider to serve the stream t...
