Free induction signal from biexcitons and bound excitons
(American Physical Society (APS), 1997)A theory of the free induction signal from biexcitons and bound excitons is presented. The simultaneous existence of the exciton continuum and a bound state is shown to result in a new type of time dependence of the free ... -
Free riding and participation in large scale, multi-hospital kidney exchange
(The Econometric Society, 2014)As multi-hospital kidney exchange has grown, the set of players has grown from patients and surgeons to include hospitals. Hospitals can choose to enroll only their hard-to-match patient–donor pairs, while conducting easily ... -
Free-boundary Linear Parameterization of 3D Meshes in the Presence of Constraints
(Institute of Electrical and Electronics Engineers (IEEE), 2005)Linear parameterization of 3D meshes with disk topology is usually performed using the method of barycentric coordinates pioneered by Tutte and Floater. This imposes a convex boundary on the parameterization which can ... -
The Free-Energy Landscape of Clusters of Attractive Hard Spheres
(American Association for the Advancement of Science, 2010)The study of clusters has provided the most tangible link between local geometry and bulk condensed matter. But experiments have not yet systematically explored the thermodynamics of even the smallest clusters. Here we ... -
Free-Living Tube Worm Endosymbionts Found at Deep-Sea Vents
(American Society for Microbiology, 2008)Recent evidence suggests that deep-sea vestimentiferan tube worms acquire their endosymbiotic bacteria from the environment each generation; thus, free-living symbionts should exist. Here, free-living tube worm symbiont ... -
Free-standing kinked nanowire transistor probes for targeted intracellular recording in three dimensions
(2013)Recording intracellular bioelectrical signals is central to understanding the fundamental behaviour of cells and cell-networks in, for example, neural and cardiac systems1–4. The standard tool for intracellular recording, ... -
Free-Standing Mechanical and Photonic Nanostructures in Single-Crystal Diamond
(American Chemical Society (ACS), 2012)A variety of nanoscale photonic, mechanical, electronic, and optoelectronic devices require scalable thin film fabrication. Typically, the device layer is defined by thin film deposition on a substrate of a different ... -
Freedom and the Ability to Sin

Freeze/Thaw-Induced Embolism: Probability of Critical Bubble Formation Depends on Speed of Ice Formation
(Frontiers Research Foundation, 2012)Bubble formation in the conduits of woody plants sets a challenge for uninterrupted water transportation from the soil up to the canopy. Freezing and thawing of stems has been shown to increase the number of air-filled ... -
Freezing of compact random heteropolymers with correlated sequence fluctuations
(AIP Publishing, 1998)Random heteropolymers (RHPs) with uncorrelated sequence fluctuations on the segmental scale can undergo a transition wherein, below a certain temperature, the thermodynamics is determined by a few dominant conformations. ... -
FREQ-Seq: A Rapid, Cost-Effective, Sequencing-Based Method to Determine Allele Frequencies Directly from Mixed Populations
(Public Library of Science, 2012)Understanding evolutionary dynamics within microbial populations requires the ability to accurately follow allele frequencies through time. Here we present a rapid, cost-effective method (FREQ-Seq) that leverages Illumina ... -
Frequency combs induced by phase turbulence

Frequency Domain Multimodel Analysis of the Response of Atlantic Meridional Overturning Circulation to Surface Forcing
(American Meteorological Society, 2013)The dynamics of the Atlantic meridional overturning circulation (AMOC) vary considerably among different climate models; for example, some models show clear peaks in their power spectra while others do not. To elucidate ... -
Frequency of Price Adjustment and Pass-through
(Oxford University Press (OUP), 2010)We empirically document using U.S. import prices that on average goods with a high frequency of price adjustment have a long-run pass-through that is at least twice as high as that of low-frequency adjusters. We show ... -
Frequency response of LaAlO3/SrTiO3 all-oxide field-effect transistors
(Elsevier BV, 2012)The frequency response of all oxide field-effect transistors with amorphous LaAlO3 on a crystalline SrTiO3 substrate is reported. The intrinsic cut-off frequencies of 4 μm gate-length devices are found to be approximately ... -
Frequent summer temperature extremes reflect changes in the mean, not the variance

FRESCo: finding regions of excess synonymous constraint in diverse viruses
(BioMed Central, 2015)Background: The increasing availability of sequence data for many viruses provides power to detect regions under unusual evolutionary constraint at a high resolution. One approach leverages the synonymous substitution rate ... -
Fresh air in the 21st century?
(Wiley-Blackwell, 2003)Ozone is an air quality problem today for much of the world's population. Regions can exceed the ozone air quality standards (AQS) through a combination of local emissions, meteorology favoring pollution episodes, and the ... -
FRET measurements of cell-traction forces and nano-scale clustering of adhesion ligands varied by substrate stiffness
(National Academy of Sciences, 2005)The mechanical properties of cell adhesion substrates regulate cell phenotype, but the mechanism of this relation is currently unclear. It may involve the magnitude of traction force applied by the cell, and/or the ability ... -
Friedel oscillations as a probe of fermionic quasiparticles
