Current Biology, 2015 The sudden appearance of fossils that marks the so-called 'Cambrian explosion' has intrigued and exercised biologists since Darwin's time. In On the Origin of Species, Darwin made it clear that he believed that ancestral forms 'lived long before' their first fossil representatives.

Noncrossing partitions and the shard intersection order [PDF]
, 2009 We define a new lattice structure on the elements of a finite Coxeter group W. This lattice, called the shard intersection order, is weaker than the weak order and has the noncrossing partition lattice NC(W) as a sublattice. The new construction of NC(W)

Examining the Emotional Tone of Student Evaluations of Teaching
Canadian Journal of Learning and TechnologyStudent-written evaluation (N = 600) of professors was examined to determine the emotional tone of the words used to evaluate faculty. Using the revised Dictionary of Affect (DOA; Whissell, 2009), evaluation words (N = 26,764) uploaded to the Rate My ...

Advanced Healthcare Materials, EarlyView.A bioassembly approach is described using photo‐crosslinked gelatin‐based microgels containing calcium peroxide (CaO2) to generate oxygen (O2) and enhance cell survival in hypoxic conditions (1% O2). Bioassembly enables spatial patterning of individual CaO2‐laden and mesenchymal stem cell (MSC)‐laden microgels and allows for decoupling and mitigating ...

An analogue of distributivity for ungraded lattices [PDF]
, 2005 In this paper, we define a property, trimness, for lattices. Trimness is a not-necessarily-graded generalization of distributivity; in particular, if a lattice is trim and graded, it is distributive.
