In this paper we propose an extension of the Scalar-CostaScheme (SCS), called Soft-SCS, which offers better or equal achievable rates than SCS for the AWGN channel. After recalling the principle of SCS we highlight its secure implementations regarding the Watermarked contents Only Attack, and we also describe the relations between the alphabet size and the secure embedding parameters. Since the...

infiltration and its modeling are important in design and implementation of irrigation projects, drainage, water-resources management, soil-conservation, hydrological studies, and artificial-recharge of groundwater and are influenced by different characteristics of soil and infiltrated water including the amount of salinity and sodium. the aim of this study was to evaluate the infiltration mode...

Based on a fully coupled, high-resolution regional climate model, this study analyzed three-dimensional temperature and momentum changes in the South China Sea (SCS) from 1970 to 2000, during which period the climate shifts from a decadal La Ni~ na-like condition (before 1976/1977) to a decadal El Ni~ no-like condition afterward. With a set of partially coupled experiments, sea surface temperat...

Recent studies have shown that stellate cells (SCs) of the medial entorhinal cortex become hyper-excitable in animal models of temporal lobe epilepsy. These studies have also demonstrated the existence of recurrent connections among SCs, reduced levels of recurrent inhibition in epileptic networks as compared to control ones, and comparable levels of recurrent excitation among SCs in both netwo...

Tides and their dynamic processes in the South China Sea (SCS) are studied by assimilating Topex/Poseidon altimetry data into a barotropic ocean tide model for the eight major constituents (M2 S2 K1 O1 N2 K2 P1 Q1) using a tidal data inversion scheme. High resolution ( 10 km) and large model domain are adopted to better resolve the physical processes involved and to minimize the uncertainty fro...

Flow patterns may affect the potential of thrombus formation following plaque rupture. Computational fluid dynamics (CFD) were employed to assess hemodynamic conditions, and particularly flow recirculation and vortex formation in reconstructed arterial models associated with ST-elevation myocardial infraction (STEMI) or stable coronary stenosis (SCS) in the left anterior descending coronary art...

Digital watermarking has been proposed for the copyright protection of multimedia documents, e.g., natural images, audio, video. One important unsolved problem in the field of digital watermarking is the synchronization of the watermark receiver after D/A-A/D conversion or local desynchronization attacks, e.g. StirMark’s random bending attack. In this paper, we present a channel model for water...
