• #### Balancing anti-herbivore benefits and anti-pollinator costs of defensive mutualists ﻿

(2014)
Quantifying costs and benefits of ostensibly mutualistic interactions is an important step toward understanding their evolutionary trajectories. In food-for-protection interactions between ants and extrafloral nectar ...
• #### Band Jahn-Teller structural phase transition inﾠY2In ﻿

(2018)
The number of paramagnetic materials that undergo a structural phase transition is rather small, which can perhaps explain the limited understanding of the band Jahn-Teller mechanism responsible for this effect. Here we ...

• #### A Bayesian Approach to Social Structure Uncovers Cryptic Regulation of Group Dynamics in Drosophila melanogaster ﻿

(2015)
Understanding the mechanisms that give rise to social structure is central to predicting the evolutionary and ecological outcomes of social interactions. Modeling this process is challenging, because all individuals ...
• #### Bayesian inference of phylogenetic networks from bi-allelic genetic markers ﻿

(2018)
Phylogenetic networks are rooted, directed, acyclic graphs that model reticulate evolutionary histories. Recently, statistical methods were devised for inferring such networks from either gene tree estimates or the sequence ...
• #### Bayesian Inference of Reticulate Phylogenies under the Multispecies Network Coalescent ﻿

(2016)
The multispecies coalescent (MSC) is a statistical framework that models how gene genealogies grow within the branches of a species tree. The field of computational phylogenetics has witnessed an explosion in the development ...
• #### Beam Energy Dependence of Jet-Quenching Effects in $\mathrm{Au}+\mathrm{Au}$ Collisions at $\sqrt{{s}_{\mathrm{NN}}}=7.7$, 11.5, 14.5, 19.6, 27, 39, and 62.4 GeV ﻿

(2018)
We report measurements of the nuclear modification factor RCP for charged hadrons as well as identified π+(−), K+(−), and p(¯p) for Au+Au collision energies of √sNN=7.7, 11.5, 14.5, 19.6, 27, 39, and 62.4 GeV. We observe ...
• #### Beam Energy Dependence of Moments of the Net-Charge Multiplicity Distributions in Au+Au Collisions at RHIC ﻿

(2014)
We report the first measurements of the moments—mean (M), variance (σ2), skewness (S), and kurtosis (κ)—of the net-charge multiplicity distributions at midrapidity in Au+Au collisions at seven energies, ranging from √sNN=7.7 ...
• #### Beam energy dependence of rapidity-even dipolar flow in Au+Au collisions ﻿

(2018)
New measurements of directed flow for charged hadrons, characterized by the Fourier coefficient v1, are presented for transverse momenta pT, and centrality intervals in Au+Au collisions recorded by the STAR experiment for ...
• #### Beam-Energy Dependence of Charge Separation along the Magnetic Field in Au+Au Collisions at RHIC ﻿

(2014)
Local parity-odd domains are theorized to form inside a quark-gluon plasma which has been produced in high-energy heavy-ion collisions. The local parity-odd domains manifest themselves as charge separation along the magnetic ...
• #### Beam-Energy Dependence of Directed Flow of $\mathrm{\ensuremath{\Lambda}}$, $\overline{\mathrm{\ensuremath{\Lambda}}}$, ${K}^{\ifmmode\pm\else\textpm\fi{}}$, ${K}_{s}^{0}$, and $\ensuremath{\phi}$ in $\mathrm{Au}+\mathrm{Au}$ Collisions ﻿

(2018)
Rapidity-odd directed-flow measurements at midrapidity are presented for Λ, ¯Λ, K±, K0s, and ϕ at √sNN=7.7, 11.5, 14.5, 19.6, 27, 39, 62.4, and 200 GeV in Au+Au collisions recorded by the Solenoidal Tracker detector at the ...
• #### Beam-Energy Dependence of the Directed Flow of Protons, Antiprotons, and Pions in Au+Au Collisions ﻿

(2014)
Rapidity-odd directed flow (v1) measurements for charged pions, protons, and antiprotons near midrapidity (y=0) are reported in √sNN=7.7, 11.5, 19.6, 27, 39, 62.4, and 200 GeV Au+Au collisions as recorded by the STAR ...
• #### Beam-energy-dependent two-pion interferometry and the freeze-out eccentricity of pions measured in heavy ion collisions at the STAR detector ﻿

(2015)
We present results of analyses of two-pion interferometry in Au+Au collisions at √sNN=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 Energy ...
• #### Benchmark measurements and simulations of dose perturbations due to metallic spheres in proton beams ﻿

(2013)
Monte Carlo simulations are increasingly used for dose calculations in proton therapy due to its inherent accuracy. However, dosimetric deviations have been found using Monte Carlo code when high density materials are ...
• #### Bi-Phasic photocatalytic particles prepared by sequential layer depositions for water cleaning and purification ﻿

(2016)
Bi-phasic photocatalyic particles have been prepared in the form of Janus-like structures (bi-phasic materials with two distinct properties on opposing sides of the particle) using a new synthetic procedure consisting of ...
• #### Biexciton, single carrier, and trion generation dynamics in single-walled carbon nanotubes ﻿

(2013)
We present a study of free carrier photogeneration and multicarrier bound states, such as biexcitons and trions (charged excitons), in semiconducting single-walled carbon nanotubes. Pump-and-probe measurements performed ...
• #### Bifunctional metal phosphide FeMnP films from single source metal organic chemical vapor deposition for efficient overall water splitting ﻿

(2017)
Developing stable and efficient bifunctional catalysts for overall water splitting into hydrogen and oxygen is a critical step in the realization of several clean-energy technologies. Here we report a robust and highly ...

• #### Biochar and Microbial Signaling: Production Conditions Determine Effects on Microbial Communication ﻿

(2013)
Charcoal has a long soil residence time, which has resulted in its production and use as a carbon sequestration technique (biochar). A range of biological effects can be triggered by soil biochar that can positively and ...
