(2017-09-14)Department: Cell and Developmental BiologyIn normal epithelial wound repair, cells across an epithelial sheet begin a coordinated process of re-epithelialization within minutes of wounding. These coordinated behaviors are driven by a calcium wave, a rise in ...
-
(2008-12-06)Department: Earth and Environmental SciencesThis study investigates the effects of earthworm burrowing on arsenic mobility and speciation in soil. The use of roxarsone in the poultry industry as a feed supplement is an increasing anthropogenic source of arsenic. ...
-
(2017-02-09)Department: Biomedical EngineeringDiffusion-weighted MRI (DWI) techniques have demonstrated the ability to non-invasively assess normal and pathological neural tissue. Recently-developed advanced DWI methods have the potential to provide quantitative ...
-
(2017-02-03)Department: PhysicsClinical imaging and biopsies are major tools for cancer diagnosis. We explore whether serial imaging coupled with a mathematical model could test and refine patient specific forecasts for therapy outcomes. We first ...
-
(2015-04-17)Department: PhysicsConventional MRI is sensitive to detect brain abnormalities non-invasively through excellent contrast generated by variation in relaxation times and water proton density. However, conventional MRI lacks the specificity and ...
-
(2011-12-13)Department: Interdisciplinary Materials ScienceProperties such as high electrical conductivity; chemical and electrochemical stability over a wide range of conditions; rapid electron transfer kinetics for different redox systems; and reproducible electrical, microstructural ...
-
(2008-04-11)Department: Chemical EngineeringThis research focuses three specific topics related to gas-phase adsorption: the synthesis and characterization of a novel carbon-silica composite adsorbent material, the diffusion of condensable vapors in single adsorbent ...
-
(2016-03-18)Department: PhysicsMeasurements of the spin-lattice relaxation rate in the rotating frame, R1rho, using spin-locking techniques have long been exploited to investigate relatively slow molecular motions and, more recently, to analyze chemical ...
-
(2014-04-27)Department: Environmental EngineeringCements blended with industrial byproducts are ubiquitous construction materials widely used in waste management. The use of blended cements as barriers for nuclear waste management necessitates prediction of durability ...
-
(2013-04-19)Department: Molecular Physiology and BiophysicsThe plasma membrane is highly organized as a means to regulate various processes including sorting of cargo for endocytosis. However, the mechanisms responsible for this organization are poorly understood. The B subunit ...
-
(2013-02-12)Department: Political ScienceThe number of children adopted into families that do not share their race, ethnicity, and national origin has steadily increased as families in developed states have turned to foreign countries for children to adopt. I ...
