Protein contacts contain important information for protein structure and functional study, but contact prediction is very challenging especially for protein families without many sequence homologs. Recently evolutionary coupling (EC) analysis, which predicts contacts by analyzing residue co-evolution in a single target family, has made good progress due to better statistical and optimization te...

Ion channels are multi-subunit, multi-modal proteins that exhibit hierarchical organization, whereby the different components interact in a cooperative manner to realize a tunable function of the channel as a whole. Synergy is thus a fundamental aspect of ion channels threaded across all three complex system characteristics, namely, hierarchy, dynamism, and regulation. A full understanding of a...

Using Serre’s adelic interpretation of the cohomology, we develop “differential and integral calculus” on an algebraic curve X over an algebraically closed constant field k of characteristic zero, define an algebraic analogs of additive and multiplicative multi-valued functions on X, and prove corresponding generalized residue theorem and A. Weil reciprocity law. Using the representation theory...

abstract conservation tillage practices integrated with appropriate residue management is an efficient approach in sustainable agriculture to prevent the removal or burning of crop residues. two years field experiments were conducted to evaluate the effect of wheat residue management on yield, yield component and morphophysiological characteristics of corn. experimental design was split plot us...

field experiment was conducted to assess the efficacy of wheat residues and different densities of sunflower in weed control during 2007 growing season. the experimental design was a randomized complete block with three replications. the experiment was set up in factorial arrangement, amount of 0, 1250, 2500, 3750, 5000 kg ha-1 of wheat residue and burning of residue (5000 kg ha-1) were the lev...

Projection Reconstruction Nuclear Magnetic Resonance (PR-NMR) is a new technique to generate multi-dimensional NMR spectra, which have discrete features that are relatively sparsely distributed in space. A small number of projections from lower dimensional NMR spectra are used to reconstruct the multi-dimensional NMR spectra. We propose an efficient algorithm which employs a blocked Gibbs sampl...
