Methanspaltung: Ein Ga3+‐modifiziertes mikroporöses Titanosilicat (ETS‐10) zeigt eine exzellente Photoaktivität in der Spaltung der C‐H‐Bindung von Methan bei Raumtemperatur. Die Aktivität wird dem Zusammenspiel aus Gallium‐induzierter Polarisation der C‐H‐Bindung und einem Titanoxid‐basierten Photoredoxprozess zugeschrieben.
Breaking down methane: A Ga3+‐modified microporous titanosilicate (ETS‐10) exhibits distinct photoactivity for the cleavage of the methane CH bond at room temperature. The highly enhanced activity is attributed to the synergistic effect of gallium‐induced CH bond polarization and a titania‐based photoredox process.
In this paper, we propose a feature generation and classification approach for universal steganalysis based on genetic algorithm (GA) and higher order statistics. The GA is utilized to select a subset of candidate features, a subset of candidate transformations to generate new features. The logistic regression model and Bayesian network model are then used as the classifier. Experimental results show...
In this paper, we propose a feature selection and transformation approach for universal steganalysis based on Genetic Algorithm (GA) and higher order statistics. We choose three types of typical statistics as candidate features and twelve kinds of basic functions as candidate transformations. The GA is utilized to select a subset of candidate features, a subset of candidate transformations and coefficients...

We present a new algorithm to compute the voxel-wise genetic contribution to brain fiber microstructure using diffusion tensor imaging (DTI) in a dataset of 25 monozygotic (MZ) twins and 25 dizygotic (DZ) twin pairs (100 subjects total). First, the structural and DT scans were linearly co-registered. Structural MR scans were nonlinearly mapped via a 3D fluid transformation to a geometrically centered...
Studies of cerebral asymmetry can open doors to understanding the functional specialization of each brain hemisphere, and how this is altered in disease. Here we examined hemispheric asymmetries in fiber architecture using diffusion tensor imaging (DTI) in 100 subjects, using high-dimensional fluid warping to disentangle shape differences from measures sensitive to myelination. Confounding effects...
