• #### A Mott insulator continuously connected to iron pnictide superconductors ﻿

(2016)
Iron-based superconductivity develops near an antiferromagnetic order and out of a bad-metal normal state, which has been interpreted as originating from a proximate Mott transition. Whether an actual Mott insulator can ...
• #### Mott localization in a pure stripe antiferromagnet ${\mathrm{Rb}}_{1\ensuremath{-}\ensuremath{\delta}}{\mathrm{Fe}}_{1.5\ensuremath{-}\ensuremath{\sigma}}{\mathrm{S}}_{2}$ ﻿

(2015)
A combination of neutron diffraction and angle-resolved photoemission spectroscopy measurements on a pure antiferromagnetic stripe Rb1−δFe1.5−σS2 is reported. A neutron diffraction experiment on a powder sample shows that ...
• #### Mott localization in a pure stripe antiferromagnet Rb1−δFe1.5−σS2 ﻿

(2015)
A combination of neutron diffraction and angle-resolved photoemission spectroscopy measurements on a pure antiferromagnetic stripe Rb1−δFe1.5−σS2 is reported. A neutron diffraction experiment on a powder sample shows that ...
• #### MUC1 stimulates EGFR expression and function in endometrial cancer ﻿

(2016)
The current standard of care for endometrial cancer patients involves hysterectomy with adjuvant radiation and chemotherapy, with no effective treatment for advanced and metastatic disease. MUC1 is a large, heavily ...
• #### Multi-component symmetry-projected approach for molecular ground state correlations ﻿

(2013)
The symmetry-projected Hartree–Fock ansatz for the electronic structure problem can efficiently account for static correlation in molecules, yet it is often unable to describe dynamic correlation in a balanced manner. Here, ...
• #### Multi-endpoint, High-Throughput Study of Nanomaterial Toxicity in Caenorhabditis elegans ﻿

(2015)
The booming nanotechnology industry has raised public concerns about the environmental health and safety impact of engineered nanomaterials (ENMs). High-throughput assays are needed to obtain toxicity data for the rapidly ...
• #### Multicanonical molecular dynamics by variable-temperature thermostats and variable-pressure barostats ﻿

(2013)
Sampling from flat energy or density distributions has proven useful in equilibrating complex systems with large energy barriers. Several thermostats and barostats are presented to sample these flat distributions by molecular ...
• #### Multilayered, Hyaluronic Acid-Based Hydrogel Formulations Suitable for Automated 3D High Throughput Drug Screening of Cancer-Stromal Cell Cocultures ﻿

(2015)
Validation of a high-throughput compatible 3D hyaluronic acid hydrogel coculture of cancer cells with stromal cells. The multilayered hyaluronic acid hydrogels improve drug screening predictability as evaluated with a panel ...
• #### Multiparameter adjoint tomography of the crust and upper mantle beneath East Asia: 1. Model construction and comparisons ﻿

(2015)
We present a 3-D radially anisotropic model of the crust and mantle beneath East Asia down to 900 km depth. Adjoint tomography based on a spectral element method is applied to a phenomenal data set comprising 1.7 million ...
• #### Multiple Facets of Arabidopsis Seedling Development Require Indole-3-Butyric Acid–Derived Auxin ﻿

(2011)
Levels of auxin, which regulates both cell division and cell elongation in plant development, are controlled by synthesis, inactivation, transport, and the use of storage forms. However, the specific contributions of various ...
• #### A Multiplexable, Microfluidic Platform for the Rapid Quantitation of a Biomarker Panel for Early Ovarian Cancer Detection at the Point-of-Care ﻿

(2015)
Point-of-care (POC) diagnostic platforms have the potential to enable low-cost, large-scale screening. As no single biomarker is shed by all ovarian cancers, multiplexed biomarker panels promise improved sensitivity and ...

(2012)
• #### Multiplicity and transverse momentum dependence of two- and four-particle correlations in pPb and PbPb collisions ﻿

(2013)
Measurements of two- and four-particle angular correlations for charged particles emitted in pPb collisions are presented over a wide range in pseudorapidity and full azimuth. The data, corresponding to an integrated ...
• #### Multireference symmetry-projected variational approximation for the ground state of the doped one-dimensional Hubbard model ﻿

(2014)
The few determinant (FED) approximation introduced in our previous work [Phys. Rev. B 87, 235129 (2013)] is used to describe the ground state, characterized by well-defined spin and space group symmetry quantum numbers as ...
• #### Multiscale Approach to the Determination of the Photoactive Yellow Protein Signaling State Ensemble ﻿

(2014)
The nature of the optical cycle of photoactive yellow protein (PYP) makes its elucidation challenging for both experiment and theory. The long transition times render conventional simulation methods ineffective, and yet ...
• #### Multispacecraft observations and modeling of the 22/23 June 2015 geomagnetic storm ﻿

(2016)
The magnetic storm of 22–23 June 2015 was one of the largest in the current solar cycle. We present in situ observations from the Magnetospheric Multiscale Mission (MMS) and the Van Allen Probes (VAP) in the magnetotail, ...
• #### Munc18b is an essential gene in mice whose expression is limiting for secretion by airway epithelial and mast cells ﻿

(2012)
Airway mucin secretion and MC (mast cell) degranulation must be tightly controlled for homoeostasis of the lungs and immune system respectively. We found the exocytic protein Munc18b to be highly expressed in mouse ...
• #### Mutation of the Arabidopsis LON2 peroxisomal protease enhances pexophagy ﻿

(2014)
Peroxisomes are critical organelles housing various, often oxidative, reactions. Pexophagy, the process by which peroxisomes are selectively targeted for destruction via autophagy, is characterized in yeast and mammals but ...
• #### Mutations in Global Regulators Lead to Metabolic Selection during Adaptation to Complex Environments ﻿

(2014)
Adaptation to ecologically complex environments can provide insights into the evolutionary dynamics and functional constraints encountered by organisms during natural selection. Adaptation to a new environment with abundant ...
• #### Mutualistic interactions between Upiga virescens (Pyralidae), a pollinating seed-consumer, and Lophocereus schottii (Cactaceae) ﻿

(1999)
Pollinating seed-consuming interactions are rare, but include fig–fig wasp and yucca–yucca moth interactions, both of which are thought to be coevolved. Conditions favoring such mutualisms are poorly known but likely ...
