Hybrid nanoreceptors for high sensitivity detection of small molecules by NMR chemosensing

High-sensitivity 2H NMR in solids by 1H detection.

The 2H quadrupolar coupling is an excellent nuclear magnetic resonance (NMR) probe of segmental orientation, molecular dynamics, or hydrogen-bonding in solids and liquid crystals.1,2 It has provided information on protein dynamics3 and structure,4 on motions in polymers,5 on bond-order parameters in liquid crystals,6 on dynamics of guest molecules in zeolites,7 clays,8 and inclusion compounds,9...

extremal region detection guided by maxima of gradient magnitude

a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...

INTERACTION OF PROTEINS WITH SMALL MOLECULES

Feature Selection for Small Sample Sets with High Dimensional Data Using Heuristic Hybrid Approach

Feature selection can significantly be decisive when analyzing high dimensional data, especially with a small number of samples. Feature extraction methods do not have decent performance in these conditions. With small sample sets and high dimensional data, exploring a large search space and learning from insufficient samples becomes extremely hard. As a result, neural networks and clustering a...
