Motor proteins are active enzymatic molecules that support important cellular processes by transforming chemical energy into mechanical work. Although the structures and chemomechanical cycles of motor proteins have been ...
• #### Molecular Probe of Pairing in the BEC-BCS Crossover ﻿

(2005)
We have used optical molecular spectroscopy to probe the many-body state of paired L6i atoms near a broad Feshbach resonance. The optical probe projects pairs of atoms onto a vibrational level of an excited molecule. The ...
• #### Molecular recognition of DNA by ligands: Roughness and complexity of the free energy profile ﻿

(2013)
Understanding the molecular mechanism by which probes and chemotherapeutic agents bind to nucleic acids is a fundamental issue in modern drug design. From a computational perspective, valuable insights are gained by the ...
• #### Molecular search with conformational change: One-dimensional discrete-state stochastic model ﻿

(2018)
Molecular search phenomena are observed in a variety of chemical and biological systems. During the search, the participating particles frequently move in complex inhomogeneous environments with random transitions between ...
• #### Molecular stripping, targets and decoys as modulators of oscillations in the NF-κB/IκBα/DNA genetic network ﻿

(2016)
Eukaryotic transcription factors in the NF-κB family are central components of an extensive genetic network that activates cellular responses to inflammation and to a host of other external stressors. This network consists ...
• #### Motor proteins and molecular motors: how to operate machines at the nanoscale ﻿

(2013)
Several classes of biological molecules that transform chemical energy into mechanical work are known as motor proteins or molecular motors. These nanometer-sized machines operate in noisy stochastic isothermal environment, ...
• #### 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 ...
• #### Multidimensional Almost-Periodic Schrödinger Operators with Cantor Spectrum ﻿

(2019)
We construct multidimensional almost-periodic Schrödinger operators whose spectrum has zero lower box-counting dimension. In particular, the spectrum in these cases is a generalized Cantor set of zero Lebesgue measure.
