Public understanding of solar radiation management
(IOP Publishing, 2011)We report the results of the first large-scale international survey of public perception of geoengineering and solar radiation management (SRM). Our sample of 3105 individuals in the United States, Canada and the United ... -
A Public-Key Infrastructure for Key Distribution in TinyOS Based on Elliptic Curve Cryptography
(IEEE, 2004)We present the first known implementation of elliptic curve cryptography over F2p for sensor networks based on the 8-bit, 7.3828-MHz MICA2 mote. Through instrumentation of UC Berkeley's TinySec module, we argue that, ... -

Publicly verifiable proofs of sequential work
(ACM Press, 2013)We construct a publicly verifiable protocol for proving computational work based on collision-resistant hash functions and a new plausible complexity assumption regarding the existence of "inherently sequential" hash ... -
Publisher Correction: Precision genome editing using cytosine and adenine base editors in mammalian cells
(Springer Science and Business Media LLC, 2021-11-17) -
Pulled, Pushed and Persuaded: Explaining Women’s Mobilization into the Salvadoran Guerrilla Army
(University of Chicago Press, 2006)Using a rare representative sample of grassroots activists and nonactivists, this study identifies three paths that consistently led Salvadoran women to involvement in the FMLM guerrilla army: politicized guerillas, reluctant ... -
Pulmonary Macrophage Transplantation Therapy
(2014)SUMMARY Bone marrow transplantation is an effective cell therapy but requires myeloablation, which increases infection-risk and mortality. Recent lineage-tracing studies documenting that resident macrophage populations ... -
Pulsar Timing Constraints on Cumulative and Individual Mass of Stars in the Galactic Center
(American Astronomical Society, 2014) -
Pulsar-black hole binaries in the Galactic Centre
(Oxford University Press, 2011)Binaries consisting of a pulsar and a black hole (BH) are a holy grail of astrophysics, both for their significance for stellar evolution and for their potential application as probes of strong gravity. In spite of extensive ... -
Pulsations in short gamma ray bursts from black hole-neutron star mergers
(American Physical Society (APS), 2013)The precise origin of short gamma ray bursts (SGRBs) remains an important open question in relativistic astrophysics. Increasingly, observational evidence suggests the merger of a binary compact object system as the source ... -
Pulsed Excimer (KrF) Laser Melting of Amorphous and Crystalline Silicon Layers
(American Institute of Physics, 1985)We have investigated depth of melting as a function of pulse energy density in amorphous and crystalline silicon layers. The melting threshold for KrF laser pulses (lambda=0.249 µm, tau=24×10−9 s) in amorphous (7660-Å-thick) ... -

Pumped Helium System for Cooling Positron and Electron Traps to 1.2K
(Elsevier BV, 2011)Extremely precise tests of fundamental particle symmetries should be possible via laser spectroscopy of trapped antihydrogen (H̅) atoms. H̅ atoms that can be trapped must have an energy in temperature units that is below ... -
Punctuated Shutdown of Atlantic Meridional Overturning Circulation during Greenland Stadial 1
(Nature Publishing Group, 2016)The Greenland Stadial 1 (GS-1; ~12.9 to 11.65 kyr cal BP) was a period of North Atlantic cooling, thought to have been initiated by North America fresh water runoff that caused a sustained reduction of North Atlantic ... -
Punctures for theories of class SΓ
(Springer Verlag, 2017)With the aim of understanding compactifications of 6D superconformal field theories to four dimensions, we study punctures for theories of class S?. The class S? theories arise from M5-branes probing C-2/Gamma, an ADE ... -
Punishment’s Place: The Local Concentration of Mass Incarceration

Pure and conformal CVD nickel and nickel monosilicide in high-aspect-ratio structures analyzed by atom probe tomography
(AIP Publishing, 2017)Low-resistance and uniform contacts are needed for modern 3-D silicon transistors. The formation of high-quality and conformal nickel silicide at the interface between silicon and metal contacts is a possible solution. ... -
Pure Samples of Quark and Gluon Jets at the LHC
(Springer Verlag, 2011)Having pure samples of quark and gluon jets would greatly facilitate the study of jet properties and substructure, with many potential standard model and new physics applications. To this end, we consider multijet and ... -
A purified population of multipotent cardiovascular progenitors derived from primate pluripotent stem cells engrafts in postmyocardial infarcted nonhuman primates
(American Society for Clinical Investigation, 2010)Cell therapy holds promise for tissue regeneration, including in individuals with advanced heart failure. However, treatment of heart disease with bone marrow cells and skeletal muscle progenitors has had only marginal ... -
The purinergic P2Y14 receptor axis is a molecular determinant for organism survival under in utero radiation toxicity
(Nature Publishing Group, 2013)In utero exposure of the embryo and fetus to radiation has been implicated in malformations or fetal death, and often produces lifelong health consequences such as cancers and mental retardation. Here we demonstrate that ...
