F-tag 501 medical director: where are we now?

It has been almost 4 years since the revised F-tag 501 medical director was released by the Centers for Medicare and Medicaid Services (CMS). There was much consternation at that time regarding the impact it would have on the future of long-term care and medical director–facility relationship. Much has been written on what the medical director should be doing given the new regulations. The ques...

Spin Dynamics in Exchange-biased F/af Bilayers

The spin dynamics of the ferromagnetic pinned layer of ferro-antiferromagnetic coupled NiFe/MnNi bilayers is investigated in a broad frequency range (30 MHz-6 GHz). A phenomenological model based on the Landau-Lifshitz equation for the complex permeability of the F/AF bilayer is proposed. The experimental results are compared to theoretical predictions.

Nikon 80-400

The 80-400 f/4.5-5.6G is a relatively large and bulky lens for the genre but overall, given its size I did not find it very heavy and found it to be well balanced even on a light D7100 without optional vertical grip. If this lens had the same metal construction as the 300 f/4 or 70-200 f/2.8 it would be even heavier. There is a lot of polycarbonate in the lens similar to the other recent f/4 ra...
