Embryonic Stem Cell Proliferation Stimulated By Altered Anabolic Metabolism From Glucose Transporter 2-Transported Glucosamine
(Nature Publishing Group, 2016)The hexose transporter, GLUT2 (SLC2A2), which is expressed by mouse embryos, is important for survival before embryonic day 10.5, but its function in embryos is unknown. GLUT2 can transport the amino sugar glucosamine ... -
An Embryonic Stem Cell-Based System for Rapid Analysis of Transcriptional Enhancers
(Wiley Periodicals, Inc., 2012)With the growing use of genome-wide screens for cis-regulatory elements, there is a pressing need for platforms that enable fast and cost-effective experimental validation of identified hits in relevant developmental and ... -
Emergence and evolution of inter-specific segregating retrocopies in cynomolgus monkey (Macaca fascicularis) and rhesus macaque (Macaca mulatta)
(Nature Publishing Group, 2016)Retroposition is an RNA-mediated mechanism to generate gene duplication, and is believed to play an important role in genome evolution and phenotypic adaptation in various species including primates. Previous studies ... -
Emergence of a super-synchronized mobbing state in a large population of coupled chemical oscillators
(Nature Publishing Group, 2016)Oscillatory phenomena are ubiquitous in Nature. The ability of a large population of coupled oscillators to synchronize constitutes an important mechanism to express information and establish communication among members. ... -
Emergence of Cooperation and Evolutionary Stability in Finite Populations
(Nature Publishing Group, 2004)To explain the evolution of cooperation by natural selection has been a major goal of biologists since Darwin. Cooperators help others at a cost to themselves, while defectors receive the benefits of altruism without ... -
Emergence of reconfigurable wires and spinners via dynamic self-assembly
(Nature Publishing Group, 2015)Dissipative colloidal materials use energy to generate and maintain structural complexity. The energy injection rate, and properties of the environment are important control parameters that influence the outcome of dynamic ... -
Emergence of Reward Coding in the Olfactory System
(2016-05-17)Identifying dangerous or rewarding elements in an animal’s surroundings is an important – if not primary – function of sensory systems. This holds particularly true for the mouse olfactory system since odors convey crucial ... -
Emergence of rich visual features from general architectural and learning constraints
(2023-05-11)The human visual system supports a wide variety of behavioral capacities including categorizing objects, reading written symbols, comparing numerosities, and detecting social interactions. What constraints and forms of ... -
The Emergence of Sex Differences

Emergence of simian immunodeficiency virus in rhesus macaques is characterized by changes in structural and accessory genes that enhance fitness in the new host species
(2016-02-25)The distribution of lentiviruses among primates reflects a history of interspecies transmission and emergence of new virus-host relationships. The degree to which viruses must adapt to the genetic environment of new host ... -
Emergence of species in evolutionary “simulated annealing”
(Proceedings of the National Academy of Sciences, 2009)Which factors govern the evolution of mutation rates and emergence of species? Here, we address this question by using a first principles model of life where population dynamics of asexual organisms is coupled to molecular ... -
Emergence of Very Broad Infrared Absorption Band by Hyperdoping of Silicon with Chalcogens
(AIP Publishing, 2013)We report the near through mid-infrared (MIR) optical absorption spectra, over the range 0.05–1.3 eV, of monocrystalline silicon layers hyperdoped with chalcogen atoms synthesized by ion implantation followed by pulsed ... -
The Emergence of ʿIlm al-Bayān: Classical Arabic Literary Theory in the Arabic East in the 7th/13th Century
(2016-09-12)This dissertation identifies a turning point in the development of literary theory as a discipline in the classical Arabic-Islamic world, starting in the Arabic East in the thirteenth century under the emerging framework ... -
Emergency Department Profits Are Likely To Continue As The Affordable Care Act Expands Coverage
(Health Affairs (Project Hope), 2014)To better understand the financial viability of hospital emergency departments (EDs), we created national estimates of the cost to hospitals of providing ED care and the associated hospital revenue using hospital financial ... -
Emergent and topological phenomena in many-body systems: Quantum spin liquids and beyond
(2021-09-03)Emergence refers to the phenomena in many-body systems not obvious from microscopic details and fundamental laws. In this dissertation, I will present some of the works that study exotic emergent phe- nomena. In the first ... -
Emergent Dark Matter, Baryon, and Lepton Numbers
(Springer, 2011)We present a new mechanism for transferring a pre-existing lepton or baryon asymmetry to a dark matter asymmetry that relies on mass mixing which is dynamically induced in the early universe. Such mixing can succeed with ... -
Emergent Dirac fermions and broken symmetries in confined and deconfined phases of Z2 gauge theories
(Springer Nature, 2017)Lattice gauge theories are ubiquitous in physics, describing a wide range of phenomena from quark confinement to quantum materials. At finite fermion density, gauge theories are notoriously hard to analyze due to the fermion ... -
Emergent Forces in Health Care Management: The Role of Patients, Foundations & Digital Technology in Shaping New Product Development
(2022-09-06)This dissertation investigates the role of emerging, external forces in shaping medical product development. Drawing on concepts from the technology innovation, nonmarket strategy, and health policy literatures, I evaluate ... -
Emergent Gapless Fermions in Strongly-Correlated Phases of Matter and Quantum Critical Points
(2018-08-17)States with gapless degrees of freedom are typically more complicated and less well- understood than systems possessing a gap. In this thesis, we study strongly-correlated systems described by gapless fermions. In most of ...
