A Dysprosium Metallocene Single-Molecule Magnet Functioning at the Axial Limit.
Angewandte Chemie, 2017 ion of a chloride ligand from the dysprosium metallocene [(Cpttt )2 DyCl] (1Dy Cpttt =1,2,4-tri(tert-butyl)cyclopentadienide) by the triethylsilylium cation produces the first base-free rare-earth metallocenium cation [(Cpttt )2 Dy]+ (2Dy ) as a salt of ...

The $\pi \sigma$-Axial Exchange Current
, 1993 The axial exchange current operator that arises from the coupling of the axial field to the pion and effective scalar field in nuclei is constructed. The spatial dependence of this exchange current operator may be determined directly from the nucleon ...

On the structure of large N cancellations in baryon chiral perturbation theory [PDF]
, 2000 We show how to compute loop graphs in heavy baryon chiral perturbation theory including the full functional dependence on the ratio of the Delta--nucleon mass difference to the pion mass, while at the same time automatically incorporating the 1/N ...

Blastopore gating mechanism to regulate extracellular fluid excretion
iScience, 2023 Summary: Fluid uptake and efflux play roles in early embryogenesis as well as in adult homeostasis. Multicellular organisms have two main pathways for fluid movement: cellular-level, such as transcellular and paracellular pathways, and tissue-level ...

Improvement of solar cycle prediction: Plateau of solar axial dipole moment
, 2017 Aims. We report the small temporal variation of the axial dipole moment near the solar minimum and its application to the solar cycle prediction by the surface flux transport (SFT) model. Methods. We measure the axial dipole moment using the photospheric

Early axial spondyloarthritis [PDF]
Current Opinion in Rheumatology, 2010 To summarize recent advances in the classification of preradiographic axial spondyloarthritis (SpA).Inflammation in the sacroiliac joints precedes radiographic damage that is necessary to establish a diagnosis of ankylosing spondylitis (AS). Preradiographic axial SpA refers to patients with SpA who exhibit signs and symptoms of axial involvement, but ...
