Progress in hydrate thermodynamic study necessitates robust and fast models to be incorporated in reservoir simulation softwares. However, numerous models presented in the literature makes selection o...
Lipid-anchored DNA Mediates Vesicle Fusion as Observed by Lipid and Content Mixing
DNA Vesicles Lipids Fuses
2016/5/25
A general method for synthesizing 5(')- and 3(')-coupled DNA-lipid conjugates has been developed and employed in DNA-mediated vesicle fusion. Vesicles presenting complementary DNA fuse, resulting in b...
Formation of Supported Lipid Bilayer Composition Arrays by Controlled Mixing and Surface Capture
tetrafluorophosphite mean amplitudes of vibration bond properties

We study compact group extensions of hyperbolic diffeomorphisms. We relate mixing properties of such extensions with
accessibility properties of their stable and unstable laminations.
We show that g...

Sparse constraints on signal decompositions are justified bytypical sensor data used in a variety of signal processing fields such as acoustics, medical imaging, or wireless, but moreover can lead to ...
Information Theory Based Estimator of the Number of Sources in a Sparse Linear Mixing Model
Information Theory Estimator of the Number of Sources Sparse Linear Mixing Model
2015/9/29
In this paper we present an Information Theoretic Estimator for the number of sources mutuallydisjoint in a linear mixing model. The approach follows the Minimum Description Length prescription and is...
Detecting the Presence of Mixing with Multiscale Maximum Likelihood
Log-concave Mixture detection
