First Molar Eruption, Weaning, and Life History in Living Wild Chimpanzees
(Proceedings of the National Academy of Sciences, 2013)Understanding dental development in chimpanzees, our closest living relatives, is of fundamental importance for reconstructing the evolution of human development. Most early hominin species are believed to show rapid ... -
First molecular phylogeny of the circumtropical bivalve family Pinnidae (Mollusca, Bivalvia): Evidence for high levels of cryptic species diversity
(Elsevier BV, 2014)The family Pinnidae Leach, 1819, includes approximately 50 species of large subtidal and coastal marine bivalves. These commercially important species occur in tropical and temperate waters around the world and are most ... -
The First Myriapod Genome Sequence Reveals Conservative Arthropod Gene Content and Genome Organisation in the Centipede Strigamia maritima
(Public Library of Science, 2014)Myriapods (e.g., centipedes and millipedes) display a simple homonomous body plan relative to other arthropods. All members of the class are terrestrial, but they attained terrestriality independently of insects. Myriapoda ... -
First observations of iodine oxide from space
(American Geophysical Union, 2007)We present retrievals of IO total columns from the Scanning Imaging Absorption Spectrometer for Atmospheric Chartography (SCIAMACHY) satellite instrument. We analyze data for October 2005 in the polar regions to demonstrate ... -
First Passage Analysis of the Folding of a β-Sheet Miniprotein: Is it More Realistic Than the Standard Equilibrium Approach?
(American Chemical Society, 2014)Simulations of first-passage folding of the antiparallel β-sheet miniprotein beta3s, which has been intensively studied under equilibrium conditions by A. Caflisch and co-workers, show that the kinetics and dynamics are ... -
First phylogenetic analysis of Dryophthorinae (Coleoptera, Curculionidae) based on structural alignment of ribosomal DNA reveals Cenozoic diversification
(Wiley, 2021-02-09)Dryophthorinae is an economically important, ecologically distinct, and ubiquitous monophyletic group of pantropical weevils with more than 1,200 species in 153 genera. This study provides the first comprehensive phylogeny ... -
The First Phylogenetic Analysis of Palpigradi (Arachnida)—The Most Enigmatic Arthropod Order
(CSIRO Publishing, 2014)Palpigradi are a poorly understood group of delicate arachnids, often found in caves or other subterranean habitats. Concomitantly, they have been neglected from a phylogenetic point of view. Here we present the first ... -
First Principles Semiclassical Calculations of Vibrational Eigenfunctions
(American Institute of Physics, 2011)Vibrational eigenfunctions are calculated on-the-fly using semiclassical methods in conjunction with ab initio density functional theory classical trajectories. Various semiclassical approximations based on the time-dependent ... -
First principles study of point defects in SnS
(Royal Society of Chemistry, 2014)Photovoltaic cells based on SnS as the absorber layer show promise for efficient solar devices containing non-toxic materials that are abundant enough for large scale production. The efficiency of SnS cells has been ... -
The first record of Laboulbeniales (Fungi, Ascomycota) on Ants (Hymenoptera, Formicidae) in The Netherlands
(Ascomycete.org, 2012)Laboulbeniales (Fungi, Ascomycetes) are obligate ectoparasites of arthropods, mostly true insects. 80% of all Laboulbeniales parasitize beetles, 10% flies. Also other groups of insects are known to support Laboulbeniales ... -
First Results from Pan-STARRS1: Faint, High Proper Motion White Dwarfs in the Medium-Deep Fields
(IOP Publishing, 2011)The Pan-STARRS1 survey has obtained multi-epoch imaging in five bands (Pan-STARRS1 gP1, rP1, iP1, zP1, and yP1) on twelve “Medium Deep Fields”, each of which spans a 3.3 degree circle. For the period between Apr 2009 and ... -
The First Scale of Attention: Linguistic Form and Aesthetic Experience in the Novel
(2013-08-27)We read a novel one sentence at a time. The first scale of attention for even the longest novel is the play of forces within the thousands of individual sentences. This project aims to rescale the analysis of novelistic ... -
First Season MWA EoR Power Spectrum Results at Redshift 7
(American Astronomical Society, 2016)The Murchison Widefield Array (MWA) has collected hundreds of hours of Epoch of Reionization (EoR) data and now faces the challenge of overcoming foreground and systematic contamination to reduce the data to a cosmological ... -
First Season QUaD CMB Temperature and Polarization Power Spectra
(IOP Publishing, 2008)QUaD is a bolometric CMB polarimeter sited at the South Pole, operating at frequencies of 100 and 150 GHz. In this paper we report preliminary results from the first season of operation (austral winter 2005). All six CMB ... -
First Single Particle Measurements of the Proton and Antiproton Magnetic Moments
(2013-09-23)We report a new comparison of the proton (p) and antiproton \((\bar{p})\) magnetic moments. In nuclear magnetons, \(\mu_p/\mu_N\) = 2.792 846 (7) [2.5 ppm], while \(\mu_{\bar{p}}/\mu_N\) = 2.792 845 (12) [4.4 ppm]. The ... -
First stars of the ρ Ophiuchi dark cloud
(EDP Sciences, 2016)Star formation in molecular clouds can be triggered by the dynamical action of winds from massive stars. Furthermore, X-ray and UV fluxes from massive stars can influence the life time of surrounding circumstellar disks. ... -
First Structure Formation: A Simulation of Small‐Scale Structure at High Redshift
(American Astronomical Society, 2001)We describe the results of a simulation of collisionless cold dark matter in a Lambda CDM universe to examine the properties of objects collapsing at high redshift (z = 10). We analyze the halos that form at these early ... -
The First Vlbi Detection of an Ultracool Dwarf: Implications for the Detectability of Sub-Stellar Companions
(IOP Publishing, 2009)We present milliarcsecond-resolution radio very long baseline interferometry (VLBI) observations of the ultracool dwarfs TVLM 513–46546 (M8.5) and 2MASS J00361617+1821104 (L3.5) in an attempt to detect sub-stellar companions ... -
First-Person Action Experience Reveals Sensitivity to Action Efficiency in Prereaching Infants
(Proceedings of the National Academy of Sciences, 2013)Do infants learn to interpret others’ actions through their own experience producing goal-directed action, or does some knowledge of others’ actions precede first-person experience? Several studies report that motor ... -
