Experimental Detection of Sign-Reversal Pairing in Iron-Based Superconductors

open access: yes, 2009
We propose a modified Josephson corner-junction experiment which can test whether the order parameter in the iron pnictides changes sign between the electron and hole pockets of the Fermi surface.Comment: 2 pages, 2 figures; After this paper was ...

Sensitivity Function Trade-offs for Networks with a String Topology

open access: yes, 2018
We present two sensitivity function trade-offs that apply to a class of networks with a string topology. In particular we show that a lower bound on the H-infinity norm and a Bode sensitivity relation hold for an entire family of sensitivity functions ...

A round-trip ticket: the importance of release processes for in-stream nutrient spiraling [PDF]

open access: yes, 2016
Most nutrient-spiraling studies have focused on estimates of gross uptake (Ugross), which show that streams take up dissolved inorganic nutrients very efficiently. However, studies based on estimates of net uptake (Unet) emphasize that streams tend to be

Estimation of stress intensity factor for corrosive environment [PDF]

open access: yes, 2010
Corrosion fatigue refers to the damage and failure of material under the combined action of cyclic stresses and corrosive environment, which affect the life of fatigue critical structures, such as, aero structures, submarine hulls, offshore structures ...

The impact of antiandrogen 2-hydroxyflutamide on the expression of steroidogenic enzymes in cultured porcine ovarian follicles [PDF]

open access: yes, 2014
We used our model system for agonism and antagonism of the androgen receptor (AR), in which the porcine ovarian follicles were exposed on the excessive concentration of an AR agonist- testosterone (T) or an AR antagonist- 2-hydroxyflutamide (2-Hf) to: (1)

Magnetic Properties of (VO)_2P_2O_7 from Frustrated Interchain Coupling

open access: yes, 1998
Neutron-scattering experiments on (VO)_2P_2O_7 reveal both a gapped magnon dispersion and an unexpected, low-lying second mode. The proximity and intensity of these modes suggest a frustrated coupling between the alternating spin chains.
