Buried-Anode Technology Leads to Advanced Lithium Batteries
A technology developed at the National Renewable Energy Laboratory has sparked a start-up company that has attracted funding from the Advanced Projects Research Agency-Energy (ARPA-E). Planar Energy, Inc. has licensed NREL\u27s buried-anode technology and put it to work in solid-state lithium batteries. The company claims its large-format batteries can achieve triple the performance of today\u27s lithium-ion batteries at half the cost, and if so, they could provide a significant boost to the emerging market for electric and plug-in hybrid vehicles

Stable transport in proton driven Fast Ignition
Proton beam transport in the context of proton driven Fast Ignition is
usually assumed to be stable due to protons high inertia, but an analytical
analysis of the process is still lacking. The stability of a charge and current
neutralized proton beam passing through a plasma is therefore conducted here,
for typical proton driven Fast Ignition parameters. In the cold regime, two
fast growing Buneman-like modes are found, with an inverse growth-rate much
smaller than the beam time-of-flight to the target core. The stability issue is
thus not so obvious, and Kinetic effects are investigated. One unstable mode is
found stabilized by the background plasma protons and electrons temperatures.
The second mode is also damped, providing the proton beam thermal spread is
larger than 10 keV. In Fusion conditions, the beam propagation should
therefore be stable.Comment: Submitted to Po
Threshold Resummation in Momentum Space from Effective Field Theory
Methods from soft-collinear effective theory are used to perform the
threshold resummation of Sudakov logarithms for the deep-inelastic structure
function F_2(x,Q^2) in the endpoint region x->1 directly in momentum space. An
explicit all-order formula is derived, which expresses the short-distance
coefficient function C in the convolution F_2=C*phi_q in terms of Wilson
coefficients and anomalous dimensions defined in the effective theory.
Contributions associated with the physical scales Q^2 and Q^2(1-x) are
separated from non-perturbative hadronic physics in a transparent way. A
crucial ingredient to the momentum-space resummation is the exact solution to
the integro-differential evolution equation of the jet function, which is
derived. The methods developed in this Letter can be applied to many other hard
QCD processes.Comment: 4 pages, 1 figure. Version to appear in PR
Public Perceptions of the Midwest’s Pavements - Minnesota - Phase III (Targeted Survey Report)
This research is being conducted as part of a larger study of the public’s perceptions of state-maintained rural highway pavements in Wisconsin, Minnesota, and Iowa. Later stages of this project will involve interviewing residents of the three states by telephone to gather information about people’s concerns about the pavements in general and specific stretches of highways in particular. Information from this effort is expected to aid the states’ Departments of Transportation refine the standards used to set pavement reconstruction priorities to better meet the needs of residents

Quantum Theory of Probability and Decisions
The probabilistic predictions of quantum theory are conventionally obtained
from a special probabilistic axiom. But that is unnecessary because all the
practical consequences of such predictions follow from the remaining,
non-probabilistic, axioms of quantum theory, together with the
non-probabilistic part of classical decision theory
Tilings, Chern-Simons Theories and M2 Branes
A new infinite class of Chern-Simons theories is presented using brane
tilings. The new class reproduces all known cases so far and introduces many
new models that are dual to M2 brane theories which probe a toric non-compact
CY 4-fold. The master space of the quiver theory is used as a tool to construct
the moduli space for this class and the Hilbert Series is computed for a
selected set of examples.Comment: 23 pages, minor changes, references adde
