SIMULATION STUDY ON THE EFFECT OF SAND DIGGING AND HEAPING ON SAR IMAGING IN THE PEARL RIVER ESTUARY [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
There are frequent sand digging and heaping activities in shoal in the Pearl River Estuary (PRE). Water depth has changed in patches, which can be imaged by synthetic aperture radar (SAR).

Disentanglement Dynamics in Nonequilibrium Environments

Entropy, 2022
We theoretically study the non-Markovian disentanglement dynamics of a two-qubit system coupled to nonequilibrium environments with nonstationary and non-Markovian random telegraph noise statistical properties. The reduced density matrix of the two-qubit system can be expressed as the Kraus representation in terms of the tensor products of the single ...

Hyper-Selection in Dynamic Environments [PDF]

2008 IEEE Congress on Evolutionary Computation (IEEE World Congress on Computational Intelligence), 2008
In recent years, several approaches have been developed for genetic algorithms to enhance their performance in dynamic environments. Among these approaches, one kind of methods is to adapt genetic operators in order for genetic algorithms to adapt to a new environment.

CO2 concentration detection based on TDLAS technology [PDF]

MATEC Web of Conferences
With the growth of industrialization and energy consumption, a large number of CO2 gas emissions lead to global warming and cause a series of environmental problems, which have a great negative impact on the global ecosystem.

Adaptive multi-wavelength temperature retrieval method [PDF]

MATEC Web of Conferences
This paper addresses the limitations of traditional multi-spectral temperature measurement methods, such as low computational efficiency and sensitivity to noise, by introducing an efficient temperature inversion method based on a collaborative design of

A rush of blood to the head: Temporal dimensions of retrenchment, environment and turnaround performance [PDF]

, 2017
In this work we test the general assumption in the turnaround literature that time is critical for firm survival, especially during the retrenchment stage.We study three time dimensions of change at this stage: timing, speed and rhythm.

MCAF-Net: A non-invasive early screening method for coronary artery disease based on a multi-scale cross-modal model [PDF]

MATEC Web of Conferences
Coronary artery disease (CAD) is one of the leading causes of death worldwide. Achieving early, non-invasive, and highly accurate detection of CAD is crucial for reducing its mortality rate.

EDEN: evolutionary dynamics within environments [PDF]

Bioinformatics, 2017
AbstractSummaryMetagenomics revolutionized the field of microbial ecology, giving access to Gb-sized datasets of microbial communities under natural conditions. This enables fine-grained analyses of the functions of community members, studies of their association with phenotypes and environments, as well as of their microevolution and adaptation to ...

Mutator dynamics in fluctuating environments [PDF]

Proceedings of the Royal Society of London. Series B: Biological Sciences, 2002
Populations with high mutation rates (mutator clones) are being found in increasing numbers of species, and a clear link is being established between the presence of mutator clones and drug resistance. Mutator clones exist despite the fact that in a constant environment most mutations are deleterious, with the spontaneous mutation rate generally held ...
