Complex Earthquakes and Teichmuller Theory
(American Mathematical Society, 1998)It is known that any two points in Teichmuller space are joined by an earthquake path. In this paper we show any earthquake path \(\mathbb{R} \rightarrow T(S)\) extends to a proper holomorphic mapping of a simplyconnected ... -
Complex Evolutionary Events at a Tandem Cluster of Arabidopsis thaliana Genes Resulting in a Single-Locus Genetic Incompatibility
(Public Library of Science, 2011)Non-additive interactions between genomes have important implications, not only for practical applications such as breeding, but also for understanding evolution. In extreme cases, genes from different genomic backgrounds ... -
Complex impedance of a spin injecting junction
(AIP Publishing, 2002)Theory of the ac spin injection from a ferromagneticelectrode into a normal conductor through a tunnel or Schottky contact is developed. Diffusion and relaxation of nonequilibrium spins results in a frequency-dependent ... -
Complex Interactions Between Estrogen, Strain, and Exercise-Induced Periosteal Bone Growth
(John Wiley & Sons, 2007)Understanding the relationship between bone strain and bone growth is critical for interpreting variations in skeletal robusticity. Recently we presented a model for interactions between estrogen, strain, and periosteal ... -
Complex Modular Architecture Around a Simple Toolkit of Wing Pattern Genes
(Springer Science and Business Media LLC, 2017-01-30)Identifying the genomic changes that control morphological variation and understanding how they generate diversity is a major goal of evolutionary biology. In Heliconius butterflies, a small number of genes control the ... -
Complex molecule formation around massive young stellar objects
(Royal Society of Chemistry (RSC), 2014)Interstellar complex organic molecules were first identified in the hot inner regions of massive young stellar objects (MYSOs), but have more recently been found in many colder sources, indicating that complex molecules ... -
Complex moments of parton distributions and new sum rules

Complex N-Heterocycle Synthesis via Iron-Catalyzed, Direct C-H Bond Amination
(American Association for the Advancement of Science (AAAS), 2013)The manipulation of traditionally unreactive functional groups is of paramount importance in modern chemical synthesis. We have developed an iron-dipyrrinato catalyst that leverages the reactivity of iron-borne metal-ligand ... -
The Complex Optical to Soft X-Ray Spectrum of Low-Redshift Radio-quiet Quasars. II. Comparison with Free-Free and Accretion Disk Models
(IOP Publishing, 1995)We compare the optical to soft X-ray spectral energy distributions (SEDs) of a sample of bright low-redshift (0.048 < z < 0.155), radio-quiet quasars, with a range of thermal models which have been proposed to explain the ... -
The complex optical to soft x-ray spectrum of the low-redshift radio-quiet quasars
(IOP Publishing, 1994)Eight high signal-to-noise ROSAT Position Sensitive Proportional Counter (PSPC) observations of six low-redshift (o.048 less than z less than 0.155) radio-quiet quasars have been analyzed to study ant soft excess. All the ... -
Complex Ordered Patterns in Mechanical Instability Induced Geometrically Frustrated Triangular Cellular Structures
(American Physical Society, 2014)Geometrical frustration arises when a local order cannot propagate throughout the space because of geometrical constraints. This phenomenon plays a major role in many systems leading to disordered ground-state configurations. ... -
Complex Organic Molecules During Low-Mass Star Formation: Pilot Survey Results
(IOP Publishing, 2014)Complex organic molecules (COMs) are known to be abundant toward some low-mass young stellar objects (YSOs), but how these detections relate to typical COM abundance are not yet understood. We aim to constrain the frequency ... -
Complex organic molecules in organic-poor massive young stellar objects
(EDP Sciences, 2015)Context. Massive young stellar objects (MYSOs) with hot cores are classic sources of complex organic molecules. The origins of these molecules in such sources, as well as the small- and large-scale differentiation between ... -
Complex Organic Molecules toward Embedded Low-mass Protostars
(American Astronomical Society, 2017-06-02)Complex organic molecules (COMs) have been observed toward several low-mass young stellar objects (LYSOs). Small and heterogeneous samples have so far precluded conclusions on typical COM abundances, as well as the origin(s) ... -
Complex Patterns of Gene Duplication in the APETALA3 and PISTILLATA Lineages of the Ranunculaceae
(University of Chicago Press, 2003)It has been proposed that the diversification of the MADS-box gene family of transcription factors has played a major role in the radiation of land plants. This suggestion is based on the critical roles that these genes ... -
Complex RIA calcium dynamics and its function in navigational behavior
(Landes Bioscience, 2013)Recently, we have reported novel and complex calcium dynamics in the RIA interneuron, which has been implicated in several navigational behaviors in C. elegans. Here, we review our findings on the compartmentalized and ... -
Complex Wavenumber Rossby Wave Ray Tracing
(American Meteorological Society, 2012)This paper presents a methodology for performing complex wavenumber ray tracing in which both wave trajectory and amplitude are calculated. This ray-tracing framework is first derived using a scaling in which the imaginary ... -
The Complex X‐Ray Absorbers of NGC 3516 Observed by BEPPOSAX
(IOP Publishing, 2000)In this paper we present the analysis of two broadband (0.1-150 keV) BeppoSAX observations of the Seyfert 1 galaxy NGC 3516. The two observations were taken 4 months apart, on 1996 November 8 and 1997 March 12. We report ... -

Complexes of Native Ubiquitin and Dodecyl Sulfate Illustrate the Nature of Hydrophobic and Electrostatic Interactions in the Binding of Proteins and Surfactants
(American Chemical Society (ACS), 2011)A previous study, using capillary electrophoresis (CE) [J. Am. Chem. Soc.2008, 130, 17384–17393], reported that six discrete complexes of ubiquitin (UBI) and sodium dodecyl sulfate (SDS) form at different concentrations ...
