Interferon-lambda: A potent regulator of intestinal viral infections [PDF]

open access: yes, 2017
Interferon-lambda (IFN-λ) is a recently described cytokine found to be of critical importance in innate immune regulation of intestinal viruses. Endogenous IFN-λ has potent antiviral effects and has been shown to control multiple intestinal viruses and ...

Avramenko Diode Circuit Topology for Microwave Energy Harvesting in Goubau Line and Wireless Mediums

open access: yesIEEE Access, 2018
Wireless energy harvesting at microwave frequencies is a known challenge. The transmission medium to support delivery of a wireless energy is normally an insulator that conducts mainly a displacement current.

Measuring vacuum component impedance for the Argonne Advanced Photon Source upgrade

open access: yesPhysical Review Accelerators and Beams, 2020
The Advanced Photon Source plans to upgrade to a multibend achromat (MBA) lattice that will dramatically decrease the electron beam emittance, thereby enhancing the x-ray brightness by two to three orders of magnitude.

THZ POWER DIVIDER CIRCUITS ON PLANAR GOUBAU LINES (PGLS) [PDF]

open access: yesProgress In Electromagnetics Research C, 2012
Terahertz spectroscopy is a new tool for real time biological analysis. Unfortunately, investigations on aqueous solutions remain difficult and need to work on nanovolumes. Integrated Terahertz instrumentation remains a challenge. We demonstrate that Planar Goubau Line (PGL) technology could bring a real practical solution to reach this goal.

Mode Bifurcation and Fold Points of Complex Dispersion Curves for the Metamaterial Goubau Line

open access: yes, 2009
In this paper the complex dispersion curves of the four lowest-order transverse magnetic modes of a dielectric Goubau line ($\epsilon>0, \mu>0$) are compared with those of a dispersive metamaterial Goubau line.

Magnetotelluric data processing: a case study [PDF]

open access: yes, 1988
Magnetotelluric (MT) data collected simultaneously at one or more sites may be processed by a number of different methods. Such methods attempt to remove or suppress the effect of noise on the data channels. The desired results are accurate, unbiased and

Electromagnetic surface wave propagation in a metallic wire and the Lambert $W$ function

open access: yes, 2019
We revisit the solution due to Sommerfeld of a problem in classical electrodynamics, namely, that of the propagation of an electromagnetic axially symmetric surface wave (a low-attenuation single TM$_{01}$ mode) in a cylindrical metallic wire, and his ...

Wireless Energy Harvesting by Direct Voltage Multiplication on Lateral Waves From a Suspended Dielectric Layer

open access: yesIEEE Access, 2017
This paper explores the feasibility of wireless energy harvesting by direct voltage multiplication on lateral waves. Whilst free space is undoubtedly a known medium for wireless energy harvesting, space waves are too attenuated to support realistic ...

THz surface plasmon modes on planar Goubau lines

open access: yesOptics Express, 2012
The dispersion relation and confinement of terahertz surface plasmon modes propagating along planar Goubau lines are studied using guided-wave time domain spectroscopy. We demonstrate the radial nature of the surface plasmon mode known as the Goubau mode and the transverse confinement of the electric field over a few tenths of microns (~l/10).
