Sedimentary Iron Cycling and the Origin and Preservation of Magnetization in Platform Carbonate Muds, Andros Island, Bahamas [PDF]
, 2007 Carbonate muds deposited on continental shelves are abundant and well-preserved throughout the geologic record because shelf strata are difficult to subduct and peritidal carbonate units often form thick, rheologically strong units that resist ...

Image transfer through a chaotic channel by intensity correlations
, 2005 The three-wave mixing processes in a second-order nonlinear medium can be used for imaging protocols, in which an object field is injected into the nonlinear medium together with a reference field and an image field is generated. When the reference field

Mechanisms of Body Alignment in a Diurnal Songbird Migrant
Ethology, Volume 132, Issue 6, Page 399-411, June 2026.The graphical abstract illustrates the body alignment mechanism of a diurnal songbird migrant, the dunnock (Prunella modularis). Dunnocks consistently expressed an angular body alignment, with inter‐individual variation at the level of the population.
