The forms of the neutral, non-strange pseudoscalar propagator matrix and mixed axial current correlator, 〈0|T (AμAν)|0〉, are discussed at next-toleading (one-loop) order in chiral perturbation theory, and the results compared to those obtained using QCD sum rules. This comparison provides a check of the truncations employed in the sum rule treatment of the current correlator. Values for the slo...

DNA methylation is reconfigured during male reproduction in plants, but little known regarding the mechanisms controlling these epigenetic dynamics. New research highlights how cell cycle can influence dynamics observed gametogenesis and may induce variation clonally propagated plants. Stable inheritance of marks, such as histone modifications methylation, to daughter cells crucial for transmis...

We have described a series of tethered oligonucleotide probes (triplex TOPs) that recognize one singlestranded and one double-stranded region of an RNA simultaneously through the formation of Watson-Crick and Hoogsteen base pairs, respectively. Here we describe studies on the kinetics and mechanism of triplex TOP‚RREAU association and dissociation. Because triplex TOP‚RREAU complexes cannot be ...

Human and non-human animal behavior is highly malleable adapts successfully to internal external demands. Such behavioral success stands in striking contrast the apparent instability neural activity (i.e., variability) from which it arises. Here, we summon considerable evidence across scales, species, imaging modalities that variability represents a key, undervalued dimension for understanding ...
