How cratons-extremely stable continental areas of the Earth's crust-formed and remained largely unchanged for more than 2,500 million years is much debated. Recent studies of seismic-wave receiver function data have detected a structural boundary under continental cratons at depths too shallow to be consistent with the lithosphere-asthenosphere boundary, as inferred ...

Chlorophyll fluorescence Imaging and Microscopy PAM fluorometry were applied to study spatial dynamics of photosystem II quantum yield [Formula: see text] and non-photochemical quenching (NPQ) in resting and electrically stimulated Chara corallina cells in the absence and presence of the hydrophilic electron acceptor methyl viologen (MV) in the external medium. ...

Transplantable cell sheets containing osteoblasts were fabricated from periostea on temperature-responsive culture dishes. This study demonstrated the time-course of bone regeneration in living small animals. This continuous observation of bone regeneration was achieved by micro-computed tomography (µCT), which assessed the osteogenic capability of periosteal cells without biodegradable scaffolds. Real-time bone ...

Laboratory tests in rheumatology are important tools that help to support the diagnosis of autoimmune diseases, evaluate the disease activity, monitor the side effects of therapy, and also assist the physician to exclude rheumatologic mimics. Few relevant tests should be ordered after a detailed clinical review of the patient has ...

An efficient microwave-assisted one-pot two-step protocol was developed for the construction of disubstituted 2-amino-1H-imidazoles. This process involves the sequential formation of 2,3-dihydro-2-hydroxyimidazo[1,2-a]pyrimidinium salts from readily available 2-aminopyrimidines and α-bromoketones, followed by cleavage of the pyrimidine ring with hydrazine.

Polymer nanopillars (40-80 nm in diameter and 100 nm in pitch) were fabricated at high density over large areas directly on bulk tissue culture polystyrene plates using nanoimprint lithography. Nanoporous Si molds for imprinting were generated by transfer from an anodic alumina membrane. Ultrahigh aspect ratio polymer nanopillars were formed ...

ABSTRACTRecent work in adult psycholinguistics has demonstrated that activation of semantic representations begins long before phonological processing is complete. This incremental propagation of information across multiple levels of analysis is a hallmark of adult language processing but how does this ability develop? In two experiments, we elicit measures of incremental ...

Kelly 466, 10.1038/nature09275 (2010)Our recent study of pre- and post-copulatory sexual selection in the sex-role-reversed Gulf pipefish indicates that males prefer to mate with larger females compared to smaller females, that larger females transfer more eggs per copulation than ...

Strong, long-range Coulomb interactions can lead to correlated motions of multiple charged particles, which can induce important many-body effects in semiconductors. The exciton states formed from correlated electron-hole pairs have been studied extensively, but basic properties of multiple-exciton correlations-such as coherence times, population lifetimes, binding energies and the number of ...
