Envelope biogenesis and spore formation in Bacillus subtilis
(2016-05-02)The bacterial cell wall exoskeleton (or peptidoglycan) protects cells from osmotic lysis, specifies their shape, and its biosynthetic pathway is a widely-exploited antibiotic target. My thesis research focused on defining ... -
The Envelope of Global Trade: The Political Economy and Intellectual History of Jute in the Bengal Delta, 1850s to 1950s
(2013-03-05)During the second half of the nineteenth century, peasant smallholders in the Bengal delta – an alluvial tract formed out of the silt deposits of the Ganges, Brahmaputra, and Meghna river-systems – expanded their cultivation ... -
Envelope Structure of Synechococcus sp. WH8113, A Nonflagellated Swimming Cyanobacterium
(BioMed Central, 2001)Background: Many bacteria swim by rotating helical flagellar filaments [1]. Waterbury et al. [15] discovered an exception, strains of the cyanobacterium Synechococcus that swim without flagella or visible changes in shape. ... -
The Environment and Directed Technical Change
(2009)This paper introduces endogenous and directed technical change in a growth model with environmental constraints and limited resources. A unique final good is produced by combining inputs from two sectors. One of these ... -
Environment-assisted metrology with spin qubits
(American Physical Society (APS), 2012)We investigate the sensitivity of a recently proposed method for precision measurement [Phys. Rev. Lett. 106, 140502 (2011)], focusing on an implementation based on solid-state spin systems. The scheme amplifies a quantum ... -
Environment-Assisted Precision Measurement
(American Physical Society, 2011)We describe a method to enhance the sensitivity of precision measurements that takes advantage of the environment of a quantum sensor to amplify the response of the sensor to weak external perturbations. An individual qubit ... -
Environment-Assisted Quantum Transport
(Institute of Physics, 2009)Transport phenomena at the nanoscale are of interest due to the presence of both quantum and classical behavior. In this work, we demonstrate that quantum transport efficiency can be enhanced by a dynamical interplay of ... -
Environment-Assisted Quantum Transport in Ordered Systems
(IOP Publishing, 2012)Noise-assisted transport in quantum systems occurs when quantum time evolution and decoherence conspire to produce a transport efficiency that is higher than what would be seen in either the purely quantum or purely classical ... -
Environment-Assisted Quantum Walks in Photosynthetic Energy Transfer
(American Institute of Physics, 2008)Energy transfer within photosynthetic systems can display quantum effects such as delocalized excitonic transport. Recently, direct evidence of long-lived coherence has been experimentally demonstrated for the dynamics of ... -
Environmental and Biological Controls on the Initiation and Growth of a Middle Triassic (Anisian) Reef Complex on the Great Bank of Guizhou, Guizhou Province, China
(SEPM (Society for Sedimentary Geology), 2006)The Great Bank of Guizhou (GBG) is an isolated Late Permian to Late Triassic carbonate platform in the Nanpanjiang Basin of Guizhou Province, southwest China. A faulted syncline exposes a cross section of the platform ... -
Environmental and Genetic Perturbations During Development Shape Multi-Organ Health Outcomes
(2020-09-10)The developmental origin of health and disease hypothesis (DOHaD) postulates that environmental and genetic factors present during prenatal and perinatal stages alter development and fundamentally influence adolescent and ... -
Environmental and Molecular Analysis of the Floral Transition in the Lower Eudicot Aquilegia Formosa
(BioMed Central, 2011)Background Flowering is a critical transition in plant development, the timing of which can have considerable fitness consequences. Until recently, research into the genetic control of flowering time and its associated ... -
Environmental Barriers to T Cell Metabolism and Function
(2022-03-17)Immunometabolism describes the interface between immune cell function and metabolism. This interplay is governed by both cell-intrinsic metabolic programs that shape immune cell function, as well as environmental metabolites ... -
Environmental Controls on Microbial Ecophysiology
(2021-08-31)Geobiology is the study of the interactions between the living and non-living components of an environment. Microbes are vital members of the Earth’s biosphere and their diverse metabolisms allow them to catalyze electron ... -
Environmental Covariation of Metazoans and Microbialites in the Lower Ordovician Boat Harbour Formation, Newfoundland
(Elsevier BV, 2017-11)An antagonistic view of the relationship between microbialites and metazoans has long been inferred, in part because of the large scale anticorrelation of these two groups through geologic time. The nexus of this relationship ... -

Environmental Exposures and Diabetes Risk
(2022-06-06)With type 2 diabetes (T2D) reaching epidemic proportions globally and domestically, and mounting evidence for the role of environmental exposures in diabetes risk, the time is ripe for further epidemiologic investigation ... -
Environmental Exposures and Female Reproductive Aging
(2021-07-12)Reproductive aging is one of the major determinants of fertility and can profoundly affect women’s health and well-being in later life. Epidemiological studies have identified external factors related to reproductive aging, ... -
Environmental Exposures, Mental Health Outcomes, and Connection to the Metabolome: An Exposomics Framework
(2023-05-12)Anxiety and depression are the most prevalent of all psychiatric disorders both domestically and globally, fueling an urgency to identify and intervene on possible individual- and population-level risk factors. With the ... -
