The next generation of electronic hardware security may be at hand as researchers at New York University Tandon School of Engineering introduce a new class of unclonable cybersecurity security primiti...
Hot Electron and Pair Production from the Texas Petawatt Laser Irradiating Thick Gold Targets
Hot Electron Pair Production the Texas Petawatt Laser Thick Gold Targets Plasma Physics
2012/5/29
We present data from electron-positron pair production by an ultra-intense laser incident on solid Au targets with thickness between 1 and 4 mm. The experiment was performed at the Texas Petawatt Lase...
Shielding Experiments Under JASMIN Collaboration at Fermilab(III) - Measurement of High-Energy Neutrons Penetrating a Thick Iron Shield from the Antiproton Production Target by AU Activation Method
JASMIN Collaboration High-Energy Neutrons Thick Iron AU Activation Method
2012/5/17
In an antiproton production (Pbar) target station of the Fermi National Accelerator Laboratory (FNAL), the secondary particles produced by bombarding a target with 120-GeV protons are shielded by a th...
On the Lx-L6micron ratio as a diagnostic for Compton-thick AGN
X-rays: general X-rays: di use background X-rays: galaxies Infrared: galaxies
2011/10/11
As the mid-IR luminosity represents a good isotropic proxy of the AGN power, a low X-ray to mid-IR luminosity ratio is often claimed to be a reliable indicator for selecting Compton-thick (CT) AGN. We...
Effect of Dust on Lyman-alpha Photon Transfer in Optically Thick Halo
Effect Photon Transfe Optically Thick
2011/9/30
We investigate the effects of dust on Ly{\alpha} photons emergent from an optically thick medium by solving the integro-differential equation of the radiative transfer of resonant photons. To solve th...
3D Finite Element Analysis on ChaHanWuSu CFRD Built on Thick Alluvium Deposits
Alluvium Deposits Concrete Faced Rockfill Dam Finite Element Analysis (FEA)
2011/12/20
As a very popular dam style, more concrete- faced rockfill dams have been built in the world, but there is presently only a few high CFRDs with dam height more than 100m built on thick alluvium deposi...
The energy budget for X-ray to infrared reprocessing in Compton-thin and Compton-thick active galaxies
The energy budget X-ray Compton-thin
2011/1/13
Heavily obscured active galactic nuclei (AGNs) play an important role in contributing to the cosmic X-ray background (CXRB). However, the AGNs found in deep X-ray surveys are often too weak to allow d...
