1-D Van der Waals Foams Heated by Ion Beam Energy Deposition (open access)

1-D Van der Waals Foams Heated by Ion Beam Energy Deposition

One dimensional simulations of various initial average density aluminum foams (modeled as slabs of solid metal separated by low density regions) heated by volumetric energy deposition are conducted with a Lagrangian hydrodynamics code using a van der Waals equation of tate (EOS). The resulting behavior is studied to facilitate the design of future warm dense matter (WDM) experiments at LBNL. In the simulations the energy deposition ranges from 10 to 30 kJ/g and from 0.075 to 4.0 ns total pulse length, resulting in temperatures from approximately 1 o 4 eV. We study peak pressures and temperatures in the foams, expansion velocity, and the phase evolution. Five relevant time scales in the problem are identified. Additionally, we present a method for characterizing the level of inhomogeneity in a foam target as it is heated and the time it takes for a foam to homogenize.

8-oxoguainine enhances bending of DNA that favors binding of glycosylases (open access)

8-oxoguainine enhances bending of DNA that favors binding of glycosylases

Molecular dynamics (MD) simulations were carried out on the DNA oligonucleotide GGGAACAACTAG:CTAGTTGTTCCC in its native form and with guanine in the central G19:C6 base pair replaced by 8-oxoguanine (8oxoG). A box of explicit water molecules was used for solvation and Na+ counterions were added to neutralize the system. The direction and magnitude of global bending were assessed by a technique used previously to analyze simulations of DNA containing a thymine dimer. The presence of 8oxoG did not greatly affect the magnitude of DNA bending; however, bending into the major groove was significantly more probable when 8oxoG replaced G19. Crystal structures of glycosylases bound to damaged-DNA substrates consistently show a sharp bend into the major groove at the damage site. We conclude that changes in bending dynamics that assist the formation of this kink are a part of the mechanism by which glycosylases of the base excision repair pathway recognize the presence of 8oxoG in DNA.

9/11 Commission Recommendations: The Senate Confirmation Process for Presidential Nominees

On July 22, 2004, the National Commission on Terrorist Attacks Upon the United States, known as the 9/11 Commission, issued its final report, detailing the events up to and including the September 11, 2001 terrorist attacks upon the United States. The 9/11 Commission recommended that the Senate adopt rules requiring hearings and votes to confirm or reject national security nominees within 30 days of their submission at the start of each new presidential administration. Implementing the commission's proposal would involve imposing new restrictions on both the power of committee chairs to control the agenda of their committees and the rights of Senators to delay or block nominations through holds and extended debate. This report discusses in detail this proposal, how it could be implemented, and the potential effects of its implementation.

A 15-T Pulsed Solenoid for a High-Power Target Experiment (open access)

A 15-T Pulsed Solenoid for a High-Power Target Experiment

The MERIT experiment, which ran at CERN in 2007, is a proof-of-principle test for a target system that converts a 4-MW proton beam into a high-intensity muon beam for either a neutrino factory complex or a muon collider. The target system is based on a free mercury jet that intercepts an intense proton beam inside a 15-T solenoidal magnetic field. Here, we describe the design and performance of the 15-T, liquid-nitrogen-precooled, copper solenoid magnet.

A 200 Year Celebration: The Declaration and Address as an Evangelistic Action Place for the End Times transcript

A 200 Year Celebration: The Declaration and Address as an Evangelistic Action Place for the End Times

Lecture given Wednesday, September 23, 2009, 4:00 PM at Abilene Christian University: "In 1809, Thomas Campbell produced a document that has cast a long shadow over the Stone-Campbell Movement. He proposed the theme "the quest for Christian unity, peace, and purity." We will comment upon the literary composition and religious soils of this influential agenda, especially in Pennsylvania and Ireland, as reflected in recent literature; the role of scripture and its interpretation in accomplishing Campbell's goals; the eschatological unfolding of his vision; and important theological assumptions."

201 MHz Cavity R&D for MUCOOL and MICE (open access)

201 MHz Cavity R&D for MUCOOL and MICE

We describe the design, fabrication, analysis and preliminary testing of the prototype 201 MHz copper cavity for a muon ionization cooling channel. Cavity applications include the Muon Ionization Cooling Experiment (MICE) as well as cooling channels for a neutrino factory or a muon collider. This cavity was developed by the US muon cooling (MUCOOL) collaboration and is being tested in the MUCOOL Test Area (MTA) at Fermilab. To achieve a high accelerating gradient, the cavity beam irises are terminated by a pair of curved, thin beryllium windows. Several fabrication methods developed for the cavity and windows are novel and offer significant cost savings as compared to conventional construction methods. The cavity's thermal and structural performances are simulated with an FEA model. Preliminary high power RF commissioning results will be presented.
