Further investigation of empirical path-loss modeling for short forested paths
Proceedings of the 2012 IEEE International Symposium on Antennas and Propagation, 2012 This paper reports an experimental study of path-loss modeling in foliage environments for VHF and UHF short-range applications. Through the investigation, it is found that although the path loss in a forest can be conveniently modeled using linear regression, it is difficult to apply the extracted information to other forests due to the variety of ...

The disease mutation A77V in Ryanodine receptor RyR2 induces changes in energy conduction pathways in the protein [PDF]
, 2011 Energetically responsive residues of the 217 amino acid N-terminal domain of the cardiac Ryanodine receptor RyR2 are identified by a simple elastic net model. These residues lie along a hydrogen bonded path through the protein.

Advanced Engineering Materials, EarlyView.Collagen hydrolysate is evaluated as a sustainable binder for MgO‐C refractories. Its thermally induced cross‐linking and gas release lead to expansion and cracking in large bricks, but tailored batches with lignin, recyclates, or fine graphite improve the gas release while thermal treatment and stability.

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy
Advanced Engineering Materials, EarlyView.This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...
