Robust variance estimation in meta‐regression with dependent effect size estimates

…, E Tipton, MC Johnson - Research synthesis …, 2010 - Wiley Online Library
Conventional meta‐analytic techniques rely on the assumption that effect size estimates from
different studies are independent and have sampling distributions with known conditional …

Computational design of transmembrane pores

C Xu, P Lu, TM Gamal El-Din, XY Pei, MC Johnson… - Nature, 2020 - nature.com
Transmembrane channels and pores have key roles in fundamental biological processes 1
and in biotechnological applications such as DNA nanopore sequencing 2 , 3 – 4 , resulting …

Time is the enemy: mortality in trauma patients with hemorrhage from torso injury occurs long before the “golden hour”

…, S Nicholson, R Cestero, MC Johnson… - The American Journal of …, 2016 - Elsevier
Introduction The concept of the “Golden Hour” has been a time-honored tenet of prehospital
trauma care, despite a paucity of data to substantiate its validity. Non-compressible torso …

Kinetically controlled overgrowth of Ag or Au on Pd nanocrystal seeds: from hybrid dimers to nonconcentric and concentric bimetallic nanocrystals

C Zhu, J Zeng, J Tao, MC Johnson… - Journal of the …, 2012 - ACS Publications
This article describes a systematic study of the nucleation and growth of Ag (and Au) on Pd
nanocrystal seeds. By carefully controlling the reaction kinetics, the newly formed Ag atoms …

Testing inflation with large scale structure: connecting hopes with reality

…, Z Huang, D Huterer, D Jeong, MC Johnson… - arXiv preprint arXiv …, 2014 - arxiv.org
The statistics of primordial curvature fluctuations are our window into the period of inflation,
where these fluctuations were generated. To date, the cosmic microwave background has …

Dynamical and gravitational instability of an oscillating-field dark energy and dark matter

MC Johnson, M Kamionkowski - Physical Review D, 2008 - APS
Coherent oscillations of a scalar field can mimic the behavior of a perfect fluid with an
equation-of-state parameter determined by the properties of the potential, possibly driving …

Extremal limits and black hole entropy

SM Carroll, MC Johnson, L Randall - Journal of High Energy …, 2009 - iopscience.iop.org
Taking the extremal limit of a non-extremal Reissner-Nordström black hole (by externally
varying the mass or charge), the region between the inner and outer event horizons …

Neutron star mergers as a probe of modifications of general relativity with finite-range scalar forces

L Sagunski, J Zhang, MC Johnson, L Lehner… - Physical Review D, 2018 - APS
Observations of gravitational radiation from compact binary systems provide an unprecedented
opportunity to test general relativity in the strong field dynamical regime. In this paper, we …

Constraining local non-Gaussianities with kinetic Sunyaev-Zel'dovich tomography

…, MS Madhavacheril, S Ferraro, MC Johnson… - Physical Review D, 2019 - APS
Kinetic Sunyaev Zel’dovich (kSZ) tomography provides a powerful probe of the radial velocity
field of matter in the Universe. By cross-correlating a high resolution cosmic microwave …

First observational tests of eternal inflation

SM Feeney, MC Johnson, DJ Mortlock, HV Peiris - Physical review letters, 2011 - APS
The eternal inflation scenario predicts that our observable Universe resides inside a single
bubble embedded in a vast inflating multiverse. We present the first observational tests of …
