(American Physical Society, 2014-04)Rapidity-odd directed flow (v[subscript 1]) measurements for charged pions, protons, and antiprotons near midrapidity (y = 0) are reported in √s[subscript NN] = 7.7, 11.5, 19.6, 27, 39, 62.4, and 200 GeV Au+Au collisions ... -
Beam-energy-dependent two-pion interferometry and the freeze-out eccentricity of pions measured in heavy ion collisions at the STAR detector
(American Physical Society, 2015-07)We present results of analyses of two-pion interferometry in Au + Au collisions at √s[subscript NN] =7.7, 11.5, 19.6, 27, 39, 62.4, and 200 GeV measured in the STAR detector as part of the BNL Relativistic Heavy Ion Collider ... -
BEAM-FORMING ERRORS IN MURCHISON WIDEFIELD ARRAY PHASED ARRAY ANTENNAS AND THEIR EFFECTS ON EPOCH OF REIONIZATION SCIENCE
(iop, 2016-03)Accurate antenna beam models are critical for radio observations aiming to isolate the redshifted 21 cm spectral line emission from the Dark Ages and the Epoch of Reionization (EOR) and unlock the scientific potential of ... -
Beam-Recoil Polarization Measurement of π[superscript 0] Electroproduction on the Proton in the Region of the Roper Resonance
(American Physical Society, 2017-07)The helicity-dependent recoil proton polarizations P[superscript '][subscript x] and P[superscript ′][subscript z] as well as the helicity-independent component P[subscript y] have been measured in the p([→ over e],e[superscript ... -
Beam-Target Double-Spin Asymmetry ALT in Charged Pion Production from Deep Inelastic Scattering on a Transversely Polarized 3He Target at 1.4<Q2<2.7 GeV2
(American Physical Society, 2012-01)We report the first measurement of the double-spin asymmetry A[subscript LT] for charged pion electroproduction in semi-inclusive deep-inelastic electron scattering on a transversely polarized [superscript 3]He target. The ... -
A beamforming approach to phase-amplitude modulation analysis of multi-channel EEG
(Institute of Electrical and Electronics Engineers (IEEE), 2012-08)Phase-amplitude modulation is a form of cross frequency coupling where the phase of one frequency influences the amplitude of another higher frequency. It has been observed in neurophysiological recordings during sensory, ... -
Beaming into the Rat World: Enabling Real-Time Interaction between Rat and Human Each at Their Own Scale
(Public Library of Science, 2012-10)Immersive virtual reality (IVR) typically generates the illusion in participants that they are in the displayed virtual scene where they can experience and interact in events as if they were really happening. Teleoperator ... -
BEAMS Lab at MIT: Status report
(Elsevier Ltd., 2009-10)The Biological Engineering Accelerator Mass Spectrometry (BEAMS) Lab at the Massachusetts Institute of Technology is a facility dedicated to incorporating AMS into life sciences research. As such, it is focused exclusively ... -
Bearing Capacity of Spatially Random Cohesive Soil Using Numerical Limit Analyses
(American Society of Civil Engineers, 2011-03)This paper describes a probabilistic study of the two dimensional bearing capacity of a vertically loaded strip footing on spatially random, cohesive soil using Numerical Limit Analyses (NLA‐CD). The analyses uses a Cholesky ... -

Beating the bugs: roles of microbial biofilms in corrosion
(Walter de Gruyter GmbH, 2013-10)Microbiologically influenced corrosion (MIC) is a complex type of environmentally assisted corrosion. Although poorly understood and challenging to ameliorate, it is increasingly appreciated that MIC accelerates failure ... -
Beating the classical limits of information transmission using a quantum decoder
(American Physical Society, 2018-01)Encoding schemes and error-correcting codes are widely used in information technology to improve the reliability of data transmission over real-world communication channels. Quantum information protocols can further enhance ... -
Beating the Random Assignment on Constraint Satisfaction Problems of Bounded Degree
(Schloss Dagstuhl--Leibniz-Zentrum fuer Informatik, 2015-08)We show that for any odd k and any instance I of the max-kXOR constraint satisfaction problem, there is an efficient algorithm that finds an assignment satisfying at least a 1/2 + Omega(1/sqrt(D)) fraction of I's constraints, ... -
Beating the SDP bound for the floor layout problem: A simple combinatorial idea
(University of Toronto Press Inc, 2017-08)For many mixed-integer programming (MIP) problems, high-quality dual bounds can be obtained either through advanced formulation techniques coupled with a state-of-the-art MIP solver, or through semi-definite programming ... -
BEATING THE SPIN-DOWN LIMIT ON GRAVITATIONAL WAVE EMISSION FROM THE VELA PULSAR
(Institute of Physics/American Astronomical Society, 2011-08)We present direct upper limits on continuous gravitational wave emission from the Vela pulsar using data from the Virgo detector's second science run. These upper limits have been obtained using three independent methods ... -
Beatquency domain and machine learning improve prediction of cardiovascular death after acute coronary syndrome
(Nature Publishing Group, 2016-10)Frequency domain measures of heart rate variability (HRV) are associated with adverse events after a myocardial infarction. However, patterns in the traditional frequency domain (measured in Hz, or cycles per second) may ... -

Beauty itself doth of itself persuade: A cross-cultural study of candidate appearance and electoral success in new democracies
(Princeton University, 2010-10)A flurry of recent studies indicates that candidates who simply look more capable or attractive are more likely to win elections. In this article, we investigate whether voters‘ snap judgments of appearance travel across ... -
The bedrock structured programming system
(Association for Computing Machinery (ACM), 2013-01-01)We report on the design and implementation of an extensible programming language and its intrinsic support for formal verification. Our language is targeted at low-level programming of infrastructure like operating systems ...
