Optimization of a Third-Order Gradiometer for Operation in Unshielded Environments [PDF]

, 2005
The optimum geometry of a third-order gradiometer for operation in unshielded environments is discussed. The optimization result depends on the specific signal and noise conditions. The fetal heart is considered as an example of the signal source.

Pregnancy shifts endothelial progenitor cell morphology and function: Role of metabolism, pro‐inflammatory cytokines and fetal sex

The Journal of Physiology, EarlyView.
Abstract figure legend We recruited non‐pregnant women (NP), women in early pregnancy (EP) and late pregnancy (LP) for isolation of endothelial colony forming cells (ECFCs) via density gradient centrifugation. Plasma supernatant was collected for analysis of markers of glucose and lipid metabolism (fasting glucose, triglycerides, cholesterol, low ...

Tetraopes Milkweed Beetle Genomes Elucidate the Adaptive Basis of a Temperate Coevolutionary Radiation

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT The coevolutionary radiation of 27 species of Tetraopes longhorned beetles and their Asclepias milkweed hosts represents a classic example of adaptive evolution driven by plant chemical defences and herbivore counteradaptations. Investigations to date, however, have focused on a single species, Tetraopes tetrophthalmus, which feeds on the ...

Performance analysis of a cylindrical eddy current brake

IET Electric Power Applications, 2012
Skin effect and armature reaction are the two major factors that effectively influence the performance of eddy current brake. Although many analytical solutions consider the armature reaction, skin effect has a significant impact on the torque-speed characteristics of the brake as the most important performance factor. This study presents an analytical
