• #### Comparison of self-consistent field convergence acceleration techniques ﻿

(2012)
The recently proposed ADIIS and LIST methods for accelerating self-consistent field (SCF) convergence are compared to the previously proposed energy-DIIS (EDIIS) + DIIS technique. We here show mathematically that the ADIIS ...
• #### Comparison of the Z/γ∗ + jets to γ + jets cross sections in pp collisions at s=8$$\sqrt{s}=8$$TeV ﻿

(2015)
A comparison of the differential cross sections for the processes Z/γ * + jets and photon (γ)+jets is presented. The measurements are based on data collected with the CMS detector at s√=8s=8 \sqrt{s}=8 TeV corresponding ...
• #### Comparison study of ring current simulations with and without bubble injections ﻿

(2016)
For many years, stand-alone ring current models have been successfully producing storm time ring current enhancements without specifying explicit localized transient injections along their outer boundaries. However, both ...
• #### Comparisons of approximate bases for hydrogen in a magnetic field ﻿

(1983)
Solutions to the diamagnetic Hamiltonian for Rydberg states of hydrogen are studied in the low-magnetic-field regime where term mixing can be ignored. Several recently proposed approximate bases are compared by calculating ...
• #### Compensatory Mutations in Predicted Metal Transporters Modulate Auxin Conjugate Responsiveness in Arabidopsis ﻿

(2013-01)
Levels of the phytohormone indole-3-acetic acid (IAA) can be altered by the formation and hydrolysis of IAA conjugates. The isolation and characterization of Arabidopsis thaliana mutants with reduced IAA-conjugate sensitivity ...
• #### Competing mechanisms and scaling laws for carbon nanotube scission by ultrasonication ﻿

(2012)
Dispersion of carbon nanotubes (CNTs) into liquids typically requires ultrasonication to exfoliate individuals CNTs from bundles. Experiments show that CNT length drops with sonication time (or energy) as a power law t?m. ...
• #### The complex of partial bases for Fn and nite generation of the Torelli subgroup of Aut(Fn) ﻿

(2013)
We study the complex of partial bases of a free group, which is an analogue for Aut(Fn) of the curve complex for the mapping class group. We prove that it is connected and simply connected, and we also prove that its ...
• #### COMPLEX VARIABILITY OF THE Hα EMISSION LINE PROFILE OF THE T TAURI BINARY SYSTEM KH 15D: THE INFLUENCE OF ORBITAL PHASE, OCCULTATION BY THE CIRCUMBINARY DISK, AND ACCRETION PHENOMENA ﻿

(2012)
We have obtained 48 high-resolution echelle spectra of the pre-main-sequence eclipsing binary system KH 15D (V582 Mon, P = 48.37 days, e ∼ 0.6, MA = 0.6M , MB = 0.7M ). The eclipses are caused by a circumbinary disk (CBD) ...
• #### Compressibility of a Fermionic Mott Insulator of Ultracold Atoms ﻿

(2015)
We characterize the Mott insulating regime of a repulsively interacting Fermi gas of ultracold atoms in a three-dimensional optical lattice. We use inﾠsitu imaging to extract the central density of the gas and to determine ...
• #### Compton scattering in strong magnetic fields: Spin-dependent influences at the cyclotron resonance ﻿

(2014)
The quantum electrodynamical (QED) process of Compton scattering in strong magnetic fields is commonly invoked in atmospheric and inner magnetospheric models of x-ray and soft gamma-ray emission in high-field pulsars and ...
• #### Computational approaches to species phylogeny inference and gene tree reconciliation ﻿

(2013)
An intricate relationship exists between gene trees and species phylogenies, due to evolutionary processes that act on the genes within and across the branches of the species phylogeny. From an analytical perspective, gene ...
• #### Configuration of the Northern Antarctic Peninsula Ice Sheet at LGM based on a new synthesis of seabed imagery ﻿

(2015)
We present a new seafloor map for the northern Antarctic Peninsula (AP), including swath multibeam data sets from five national programs. Our map allows for the examination and interpretation of Last Glacial Maximum (LGM) ...
• #### Configuring robust DNA strand displacement reactions forﾠin situﾠmolecular analyses ﻿

(2012)
The number of distinct biomolecules that can be visualized within individual cells and tissue sections via fluorescence microscopy is limited by the spectral overlap of the fluorescent dye molecules that are coupled ...
• #### Confronting climate change in the Gulf region: prospects for sustaining our ecological heritage ﻿

(2001-10)
From Texas to Florida, the Gulf coast region is rich with ecological resources that support the region’s economic wealth. Over time, human activities from dam construction to shoreline development have dramatically altered ...
• #### Connecting the Sequence-Space of Bacterial Signaling Proteins to Phenotypes Using Coevolutionary Landscapes ﻿

(2016)
Two-component signaling (TCS) is the primary means by which bacteria sense and respond to the environment. TCS involves two partner proteins working in tandem, which interact to perform cellular functions whereas limiting ...
• #### Consequences of sex-selective harvesting and harvest refuges in experimental meta-populations ﻿

(2013)
Harvesting for food or sport is often non-random with respect to demographic state, such as size or life stage. The population- level consequences of such selective harvesting depend upon which states are harvested and how ...
• #### Conservation laws and conversion efficiency in ultraintense laser-overdense plasma interactions ﻿

(2013)
Particle coupling to the oscillatory and steady-state nonlinear force of an ultraintense laser is studied through analytic modeling and particle-in-cell simulations. The complex interplay between these absorption ...
• #### Conserved Noncoding Elements in the Most Distant Genera of Cephalochordates: The Goldilocks Principle ﻿

(2016)
Cephalochordates, the sister group of vertebrates + tunicates, are evolving particularly slowly. Therefore, genome comparisons between two congeners of Branchiostoma revealed so many conserved noncoding elements (CNEs), ...
• #### Conspecific Plasticity and Invasion: Invasive Populations of Chinese Tallow (Triadica sebifera)ﾠHave Performance Advantage over Native Populations Only in Low Soil Salinity ﻿

(2013)
Global climate change may increase biological invasions in part because invasive species may have greater phenotypic plasticity than native species. This may be especially important for abiotic stresses such as salt ...
• #### The Constrained Maximal Expression Level Owing to Haploidy Shapes Gene Content on the Mammalian X Chromosome ﻿

(2015)
X chromosomes are unusual in many regards, not least of which is their nonrandom gene content. The causes of this bias are commonly discussed in the context of sexual antagonism and the avoidance of activity in the male ...
