Interference Aware-Coordinated Beamforming System in a Two-Cell Environment
(Institute of Electrical and Electronics Engineers (IEEE), 2009)In this paper, we propose jointly optimized transceiver algorithms called interference aware coordinated beamforming (IA-CBF) for a two-cell system where each base station is equipped with multiple transmit antennas. The ... -
Interference between independent fluctuating condensates
(Proceedings of the National Academy of Sciences, 2006)We consider a problem of interference between two independent condensates that lack true long-range order. We show that their interference pattern contains information about correlation functions within each condensate. ... -
Interference-mediated synaptonemal complex formation with embedded crossover designation
(Proceedings of the National Academy of Sciences, 2014)Biological systems exhibit complex patterns, at length scales ranging from the molecular to the organismic. Along chromosomes, events often occur stochastically at different positions in different nuclei but nonetheless ... -
Interferometric Approach to Measuring Band Topology in 2D Optical Lattices
(American Physical Society (APS), 2013)Recently, optical lattices with nonzero Berry’s phases of Bloch bands have been realized. New approaches for measuring Berry’s phases and topological properties of bands with experimental tools appropriate for ultracold ... -
Interferometric Measurement of Acceleration at Relativistic Speeds
(American Astronomical Society, 2017)We show that an interferometer moving at a relativistic speed relative to a point source of light offers a sensitive probe of acceleration. Such an accelerometer contains no moving parts, and is thus more robust than ... -
Interferometric Measurements of Variable 340 GHz Linear Polarization in Sagittarius A*
(IOP Publishing, 2006)Using the Submillimeter Array, we have made the first high angular resolution measurements of the linear polarization of Sagittarius A* at submillimeter wavelengths, and the first detection of intra-day variability in its ... -
Interferometric Observation of the Highly Polarized SiO Maser Emission from the v = 1, J = 5-4 Transition Associated with VY Canis Majoris
(IOP Publishing, 2004)We used the Submillimeter Array to image the SiO maser emission in the v = 1, J = 5−4 transition associated with the peculiar red supergiant VY Canis Majoris. We identified seven maser components and measured their relative ... -
Interferometric probe of paired states
(American Physical Society (APS), 2008)We propose a method for detecting paired states in either bosonic or fermionic systems using interference experiments with independent or weakly coupled low-dimensional systems. We demonstrate that our method can be used ... -
Interferometric Probes of Many-Body Localization
(American Physical Society (APS), 2014)We propose a method for detecting many-body localization (MBL) in disordered spin systems. The method involves pulsed coherent spin manipulations that probe the dephasing of a given spin due to its entanglement with a set ... -
Intergalactic Magnetic Fields from Quasar Outflows
(American Astronomical Society, 2001)Outflows from quasars inevitably pollute the intergalactic medium (IGM) with magnetic fields. The short-lived activity of a quasar leaves behind an expanding magnetized bubble in the IGM. We model the expansion of the ... -
Intergenerational Risk Sharing in the Spirit of Arrow, Debreu, and Rawls, with Applications to Social Security Design
(University of Chicago Press, 2007)This paper examines the optimal allocation of risk in an overlapping‐generations economy. It compares the allocation of risk the economy reaches naturally to the allocation that would be reached if generations behind a ... -
Intergenerational Risksharing and Equilibrium Asset Prices
(Elsevier, 2007)In the presence of overlapping generations, markets are incomplete because it is impossible to engage in risksharing trades with the unborn. In such an environment the government can use a social security system, with ... -
Intergroup Contact Facilitates Physiological Recovery following Stressful Intergroup Interactions
(Elsevier, 2010)A growing body of research has demonstrated the importance of intergroup contact in reducing fear, threat and anxiety in intergroup domains. Here we focus on the regulatory benefits of intergroup contact. We hypothesized ... -
Interhemispheric Sea-Level Forcing of the Antarctic Ice Sheet During the Last Ice Age
A long-standing hypothesis for global ice-sheet synchronization on orbital timescales invokes sea-level rise from increased loss of Northern Hemisphere (NH) ice sheets in response to insolation and greenhouse gas forcing ... -
Interim Correlated Rationalizability
(Society for Economic Theory, 2007)This paper proposes the solution concept of interim correlated rationalizability, and shows that all types that have the same hierarchies of beliefs have the same set of interim-correlated-rationalizable outcomes. This ... -
The Interjurisdictional Effects of Growth Controls on Housing Prices
(University of Chicago Press, 1987)No abstract provided. -
Interlayer Fractional Quantum Hall Effect in a Coupled Graphene Double Layer
(Springer Science and Business Media LLC, 2019-06-24)When a strong magnetic field is applied to a two-dimensional (2D) electron system, interactions between the electrons can cause fractional quantum Hall (FQH) effects. Bringing two 2D conductors close to each other, a new ... -
Interleukin-6 Secretion by Astrocytes Is Dynamically Regulated by PI3K-mTOR-Calcium Signaling
(Public Library of Science, 2014)After contusion spinal cord injury (SCI), astrocytes become reactive and form a glial scar. While this reduces spreading of the damage by containing the area of injury, it inhibits regeneration. One strategy to improve the ... -
Intermediate filaments enable pathogen docking to trigger type 3 effector translocation
(2016)Type 3 secretion systems (T3SSs) of bacterial pathogens translocate bacterial effector proteins that mediate disease into the eukaryotic cytosol. Effectors traverse the plasma membrane through a translocon pore formed by ... -
Intermediate Levels of Network Fluidity Amplify Economic Growth and Mitigate Economic Inequality in Experimental Social Networks
(Society for Sociological Science, 2015)Social connections are mutable. Prior experimental work has shown that circumstances fostering an intermediate rate of forming and breaking social ties (“network fluidity”) facilitate the maintenance of optimal levels of ...
