Origin of horsetails and the role of whole-genome duplication in plant macroevolution

Whole-genome duplication (WGD) has occurred commonly in land plant evolution and it is often invoked as a causal agent in diversification, phenotypic and developmental innovation, as well as conferring extinction resistance....

Integrated genomic and fossil evidence illuminates life’s early evolution and eukaryote origin

Establishing a unified timescale for the early evolution of Earth and life is challenging and mired in controversy because of the paucity of fossil evidence, the difficulty of interpreting it and dispute over the deepest...

The developmental biology of <i>Charnia</i> and the eumetazoan affinity of the Ediacaran rangeomorphs.
Molecular timescales estimate that early animal lineages diverged tens of millions of years before their earliest unequivocal fossil evidence. The Ediacaran macrobiota (~574 to 538 million years ago) are largely eschewed from...

Estimation of Piston Surface Temperature During Engine Transient Operation for Emissions Reduction

Piston surface temperature is an important factor in the reduction of harmful emissions in modern gasoline direct injection (GDI) engines. In transient operation, the piston surface temperature can change rapidly, increasing...

The currency, completeness and quality of systematic reviews of acute management of moderate to severe traumatic brain injury
OBJECTIVE: To appraise the currency, completeness and quality of evidence from systematic reviews (SRs) of acute management of moderate to severe traumatic brain injury (TBI). METHODS: We conducted comprehensive searches to...
