• #### PRYSM v2.0: A Proxy System Model for Lacustrine Archives ﻿

(2018)
Reconstructions of temperature and hydrology from lake sedimentary archives have made fundamental contributions to our understanding of past, present, and future climate and help evaluate general circulation models (GCMs). ...
• #### Pseudorapidity and transverse momentum dependence of flow harmonics in $p\mathrm{Pb}$ and PbPb collisions ﻿

(2018)
Measurements of azimuthal angular correlations are presented for high-multiplicity pPb collisions at √sNN=5.02TeV and peripheral PbPb collisions at √sNN=2.76TeV. The data used in this work were collected with the Compact ...
• #### Pseudorapidity dependence of long-range two-particle correlations in $p\mathrm{Pb}$ collisions at $\sqrt{{s}_{\mathit{NN}}}=5.02$ TeV ﻿

(2017)
Two-particle correlations in pPb collisions at a nucleon-nucleon center-of-mass energy of 5.02TeV are studied as a function of the pseudorapidity separation (Δη) of the particle pair at small relative azimuthal angle ...

(2015)
The pseudorapidity distribution of charged hadrons in pp collisions at s=13 TeV is measured using a data sample obtained with the CMS detector, operated at zero magnetic field, at the CERN LHC. The yield of primary charged ...

(2012)
We report the discovery of PSR J1838−0537, a gamma-ray pulsar found through a blind search of data from the Fermi Large Area Telescope (LAT). The pulsar has a spin frequency of 6.9 Hz and a frequency derivative of −2.2 × ...
• #### PSR J2021+4026 in the Gamma Cygni Region: The First Variable y-Ray Pulsar Seen by the Fermi Lat ﻿

(2013)
Long-term monitoring of PSR J2021+4026 in the heart of the Cygnus region with the Fermi Large Area Telescope unveiled a sudden decrease in flux above 100 MeV over a timescale shorter than a week. The "jump" was near MJD ...
• #### Pyoverdine, a siderophore from Pseudomonas aeruginosa, translocates into C. elegans, removes iron, and activates a distinct host response ﻿

(2018)
Pseudomonas aeruginosa, a re-emerging, opportunistic human pathogen, encodes a variety of virulence determinants. Pyoverdine, a siderophore produced by this bacterium, is essential for pathogenesis in mammalian infections. ...
• #### Quantitative analysis of gas phase molecular constituents using frequency-modulated rotational spectroscopy ﻿

(2019)
Rotational spectroscopy has been used for decades for virtually unambiguous identification of gas phase molecular species, but it has rarely been used for the quantitative analysis of molecular concentrations. Challenges ...
• #### Quantitative Analysis of α-Synuclein Solubility in Living Cells Using Split GFP Complementation ﻿

(2012)
Presently incurable, Parkinson's disease (PD) is the most common neurodegenerative movement disorder and affects 1% of the population over 60 years of age. The hallmarks of PD pathogenesis are the loss of dopaminergic ...
• #### Quantitative comparison of adaptive sampling methods for protein dynamics ﻿

(2018)
Adaptive sampling methods, often used in combination with Markov state models, are becoming increasingly popular for speeding up rare events in simulation such as molecular dynamics (MD) without biasing the system dynamics. ...
