Chromatin-Associated Proteins HP1 and Mod(mdg4) Modify Y-Linked Regulatory Variation in the Drosophila Testis
(Genetics Society of America, 2013)Chromatin remodeling is crucial for gene regulation. Remodeling is often mediated through chemical modifications of the DNA template, DNA-associated proteins, and RNA-mediated processes. Y-linked regulatory variation (YRV) ... -
Chromodynamics of Cooperation in Finite Populations
(Public Library of Science, 2007)Background: The basic idea of tag-based models for cooperation is that individuals recognize each other via arbitrary signals, so-called tags. If there are tags of different colors, then cooperators can always establish ... -
Chromosomal attachments set length and microtubule number in the Saccharomyces cerevisiae mitotic spindle
(The American Society for Cell Biology, 2014)The length of the mitotic spindle varies among different cell types. A simple model for spindle length regulation requires balancing two forces: pulling, due to microtubules that attach to the chromosomes at their ... -
Chromosomal Barcoding of E. Coli Populations Reveals Lineage Diversity Dynamics at High Resolution
(Nature Publishing Group, 2020-03)Evolutionary dynamics in large asexual populations is strongly influenced by multiple competing beneficial lineages, most of which segregate at very low frequencies. However, technical barriers to tracking a large number ... -
Chromospheric Variability in Sloan Digital Sky Survey M Dwarfs. Ii. Short-timescale Hα Variability
(American Astronomical Society, 2010)We present the first comprehensive study of short-timescale chromospheric H alpha variability in M dwarfs using the individual 15 minute spectroscopic exposures for 52,392 objects from the Sloan Digital Sky Survey. Our ... -
Chromothripsis and beyond: rapid genome evolution from complex chromosomal rearrangements
(Cold Spring Harbor Laboratory Press, 2013)Recent genome sequencing studies have identified several classes of complex genomic rearrangements that appear to be derived from a single catastrophic event. These discoveries identify ways that genomes can be altered in ... -
CHROMOTHRIPSIS FROM DNA DAMAGE IN MICRONUCLEI
(2015)Genome sequencing has uncovered a new mutational phenomenon in cancer and congenital disorders called chromothripsis. Chromothripsis is characterized by extensive genomic rearrangements and an oscillating pattern of DNA ... -
Chronaxie Measurements in Patterned Neuronal Cultures from Rat Hippocampus
(Public Library of Science, 2015)Excitation of neurons by an externally induced electric field is a long standing question that has recently attracted attention due to its relevance in novel clinical intervention systems for the brain. Here we use patterned ... -
Chronic effects of temperature on mortality in the Southeastern USA using satellite-based exposure metrics
(Nature Publishing Group, 2016)Climate change may affect human health, particularly for elderly individuals who are vulnerable to temperature changes. While many studies have investigated the acute effects of heat, only a few have dealt with the chronic ... -
Chronology and geochemistry of Taxinan basalts from the Tarim basin: evidence for Permian plume magmatism
(Chinese Academy of Sciences, 2008)A new K-Ar age of 289.6Ma has been obtained for Taxinan basalt in the southwest Tarim basin of the northwest China. This age is consistent with the Ar-Ar age of 290. 1Ma from the same sample. This dating confirms the ... -
The Chronology of Leonardo Bruni's Later Works (1437-1443)

Chronology of Linear Enamel Hypoplasia Formation in the Krapina Neanderthals
(PaleoAnthropology Society, 2014)During childhood, systemic physiological stresses such as illness, disease, and malnutrition can disrupt the growth of dental enamel. These disruptions are often recorded in the form of linear enamel hypoplasia (LEH). Many ... -
Chuar Group of the Grand Canyon: Record of Breakup of Rodinia, Associated Change in the Global Carbon Cycle, and Ecosystem Expansion by 740 Ma
(Geological Society of America, 2000)The Chuar Group (similar to 1.600 m thick) preserves a record of extensional tectonism, ocean-chemistry fluctuations, and biological diversification during the late Neoproterozoic Era. An ash layer from the top of the ... -

Circadian Control of Global Isoprene Emissions
(Nature Publishing Group, 2012)Circadian rhythms govern many aspects of our lives, and it is thought that earth-atmosphere interactions are similarly affected. In this correspondence, we show that reported circadian rhythms can be explained by a variety ... -
Circling the Spheres: A Dialogue
(Duke University Press, 1998)Presents a dialogue focusing on the notion of separate spheres in American literary history. Identification of women writers in the antebellum period; Examination of literary ethnography traditions; View on the development ... -
Circuit Lower Bounds for Low-Energy States of Quantum Code Hamiltonians
(2021-09-10)The No Low-energy Trivial States (NLTS) conjecture of Freedman and Hastings, 2014 -- which posits the existence of a local Hamiltonian with a super-constant quantum circuit lower bound on the complexity of all low-energy ... -
Circuit-to-Hamiltonian from tensor networks and fault tolerance
(2023-09-28)We define a map from an arbitrary quantum circuit to a local Hamiltonian whose ground state encodes the quantum computation. All previous maps relied on the Feynman-Kitaev construction, which introduces an ancillary `clock ...
