Cycloaddition reactions involving tetrazines have proven to be powerful bioorthogonal tools for various applications. Conceivably, sequential and selective labeling using tetrazine-based reactions can be achieved by tuning the reaction rate. By varying the substituents on tetrazines, cycloaddition rate variations of over 200 fold have been achieved with the same dienophile. Upon coupling with d...

The histones of all eukaryotes show only a low degree of primary structure homology, but our earlier crystallographic results defined a three-dimensional structural motif, the histone fold, common to all core histones. We now examine the specific architectural patterns within the fold and analyze the nature of the amino acid residues within its functional segments. The histone fold emerges as a...

This paper represent an efficient computational method to identify symmetry axis and centre curve in a 2-dimensional text, image and structure. An adaptive technique is proposed for symmetrical axis determination using mirror image. The proposed approach can adopt threshold value from first computation. Exclusive OR of logical original and mirror image is used for adopt threshold value. Here lo...

Fold duplexes transfer displacement from a lower to an upper bounding detachment system via trains of folds with broadly parallel geometries. While they have been previously recognised in orogenic systems where are considered be kinematically equivalent imbricating thrust ramps, we here describe the first example gravity-driven fold and (FATS) developed within late-Pleistocene mass transport de...

Typhoons can affect various hydrodynamic processes, such as upwelling, vertical mixing, and entrainment, which in turn influence the growth redistribution of phytoplankton. In this study, responses phytoplankton to consecutive typhoons Barijat Mangkhut summer 2018 northern South China Sea (NSCS) were investigated through combining remote sensing, numerical simulation, Argo profile data. Variati...
