Preferential Location of Germanium in the UTL and IPC-2a Zeolites
(2014)The preferential location of Ge in the double four-membered rings (D4R) of zeolite UTL has been examined with periodic density functional theory calculations. In silicate UTL, Ge atoms are preferentially sited at the T1 ... -
Preferential uptake of antioxidant carbon nanoparticles by T lymphocytes for immunomodulation
(2016)Autoimmune diseases mediated by a type of white blood cell—T lymphocytes—are currently treated using mainly broad-spectrum immunosuppressants that can lead to adverse side effects. Antioxidants represent an alternative ... -
Pressure effects in the itinerant antiferromagnetic metal TiAu
(2017)We report the pressure dependence of the Néel temperature T N up to P ≈ 27 GPa for the recently discovered itinerant antiferromagnet (IAFM) TiAu. The T N ( P ) phase boundary exhibits unconventional ... -
Prethermalization production of dark matter
(2018)At the end of inflation, the inflaton field decays into an initially nonthermal population of relativistic particles which eventually thermalize. We consider the production of dark matter via freeze-in from this relativistic ... -
Prey Limitation Drives Variation in Allometric Scaling of Predator-Prey Interactions
(2018)Ecologists have long searched for a universal size-scaling constant that governs trophic interactions. Although this is an appealing theoretical concept, predator-prey size ratios (PPSRs) vary strikingly across and within ... -
Primary Salivary Human Stem/Progenitor Cells Undergo Microenvironment-Driven Acinar-Like Differentiation in Hyaluronate Hydrogel Culture
(2016)Radiotherapy for head and neck cancer often has undesirable effects on salivary glands that lead to xerostomia or severe dry mouth, which can increase oral infections. Our goal is to engineer functional, three-dimensional ... -
Principal-component analysis of two-particle azimuthal correlations in PbPb and $p\text{Pb}$ collisions at CMS
(2017)For the first time a principle-component analysis is used to separate out different orthogonal modes of the two-particle correlation matrix from heavy ion collisions. The analysis uses data from √sNN=2.76TeV PbPb and ... -
Pro-metastatic collagen lysyl hydroxylase dimer assemblies stabilized by Fe2+-binding
(2018)Collagen lysyl hydroxylases (LH1-3) are Fe2+- and 2-oxoglutarate (2-OG)-dependent oxygenases that maintain extracellular matrix homeostasis. High LH2 levels cause stable collagen cross-link accumulations that promote ... -
Probing color coherence effects in pp collisions at √s = 7TeV
(2014)A study of color coherence effects in pp collisions at a center-of-mass energy of 7 TeV is presented. The data used in the analysis were collected in 2010 with the CMS detector at the LHC and correspond to an integrated ... -
Probing dissociative electron attachment through heavy-Rydberg ion-pair production in Rydberg atom collisions
(2016)Electron transfer in collisions between low-n, n = 12, Rydberg atoms and targets that attach low-energy electrons can lead to the formation of heavy-Rydberg ion-pair states comprising a weakly-bound positive-negative ion ... -
Probing low-density carriers in a single atomic layer using terahertz parallel-plate waveguides
(2016)As novel classes of two-dimensional (2D) materials and heterostructures continue to emerge at an increasing pace, methods are being sought for elucidating their electronic properties rapidly, non-destructively, and ... -
Probing the Surface-Vacuum Interface with Spin-Sensitive Metastable Atom Deexcitation, Electron Capture and Electron Emission Spectroscopies
(1993)Spin-Polarized Metastable Atom Deexcitation (SPMDS) and Electron Capture (ECS) Spectroscopies probe the exponential tails of electronic wavefunctions extending from the surface into the vacuum, and are consequently extremely ... -
Production of high-n strontium Rydberg atoms
(2014)The photoexcitation of strontium Rydberg atoms with n~300 is being examined using a crossed laser-atom beam approach to enable study of quasi-stable two-electron excited states and of strongly-coupled Rydberg systems. -
Production of leading charged particles and leading charged-particle jets at small transverse momenta in $pp$ collisions at $\sqrt{s}=8\text{ }\text{ }\mathrm{TeV}$
(2015)The per-event yield of the highest transverse momentum charged particle and charged-particle jet, integrated above a given pminT threshold starting at pminT=0.8 and 1 GeV, respectively, is studied in pp collisions at √s=8 ... -
Production of succinic acid by engineered E. coli strains using soybean carbohydrates as feedstock under aerobic fermentation conditions
(2013)Escherichia coli strains HL2765 and HL27659k harboring pRU600 and pKK313 were examined for succinate production under aerobic conditions using galactose, sucrose, raffinose, stachyose, and mixtures of these sugars extracted ... -
Programmable bio-nano-chip system: a flexible point-of-care platform for bioscience and clinical measurements
(2015)The development of integrated instrumentation for universal bioassay systems serves as a key goal for the lab-on-a-chip community. The programmable bio-nano-chip (p-BNC) system is a versatile multiplexed and multiclass ... -
Programmable bio-nanochip-based cytologic testing of oral potentially malignant disorders in Fanconi anemia
(2015)Fanconi anemia (FA) is caused by mutations of DNA repair genes. The risk of oral squamous cell carcinoma (OSCC) among FA patients is 800-folds higher than in the general population. Early detection of OSCC, preferably at ... -
Programming in situ immunofluorescence intensities through interchangeable reactions of dynamic DNA complexes
(2012)The regulation of antibody reporting intensities is critical to various in situ fluorescence imaging analyses. While such control is often necessary to visualize sparse molecular targets, the ability to tune marker intensities ... -
Progressive shoaling of the equatorial Pacific thermocline over the last eight glacial periods
(2015)The depth of equatorial Pacific thermocline is diagnostic of the main modes of tropical climates. Past estimates of Pacific thermocline dynamics have been reconstructed either for the Last Glacial Maximum or on longer ...
