Wavelength Dependence of Two Photon and Free Carrier Absorptions in InP
Nonlinear absorption at 1.064 and 1.535 μm wavelengths by two photon and free carrier absorption processes in undoped and Fe doped InP has been investigated.

Meteor-Head Echo Observations Using an Antenna Compression Approach with the 450 MHz Poker Flat Incoherent Scatter Radar
In this work we present a novel use of the Poker Flat Incoherent Scatter Radar (PFISR) to study meteor-head echoes with wide (W) beams.

Spectral Observations of Polar Mesospheric Summer Echoes at 33 Cm (450 Mhz) with the Poker Flat Incoherent Scatter Radar
We report on multi-beam spectral observations of polar mesospheric summer echoes (PMSE) at 450 MHz (Bragg scattering wavelength of ∼33cm) carried out with the Poker Flat Incoherent Scatter Radar (PFISR)…

Temporal Evolution of Neutral, Thermospheric Winds and Plasma Response Using PFISR Measurements of Gravity Waves
We analyze the temporal variability of the propagation and dissipation of two southeast (SE)ward-propagating gravity waves (GWs) observed by the Poker Flat Incoherent Scatter Radar (PFISR) on 13 December 2006.

Activity of New NOP Receptor Ligands in a Rat Peripheral Mononeuropathy Model: Potentiation of Morphine Anti-Allodynic Activity by NOP Receptor Antagonists
The effect of new NOP receptor agonists and antagonists in the rat chronic constriction injury model was investigated.

Efficient Duration and Hierarchical Modeling for Human Activity Recognition
In this paper, we argue that in dealing with ADLs, it is beneficial to exploit both their typical duration patterns and inherent hierarchical structures.
