Water transport, embolism recovery and water storage in trees
(2014-02-25)
The ability to maintain hydraulic continuity in the xylem is essential to supply leaves with the water that must be exchanged for carbon dioxide. The metastable nature of xylem sap causes this system to be inherently ...
Long non-coding RNAs interact with PRC1 to impact Polycomb group protein recruitment and expression of Polycomb regulated genes
(2014-02-25)
Long non-coding RNAs (lncRNAs) are increasingly recognized as important regulators of genomic processes and cellular specification. Many lncRNAs regulate chromatin by functionally impacting the epigenetic state through ...
Data-driven analysis of mitotic spindles
(2014-02-25)
We have developed a method for automatic identification and tracing of microtubules in three dimensional electron tomography datasets. Additionally, we have developed a number of statistical techniques for working with ...
Fluctuation Timescales in Bacterial Gene Expression
(2014-02-25)
The stochastic nature of intracellular chemistry guarantees that even genetically identical cells sharing an environment will differ in composition. The question of whether this chemical diversity translates into significant ...
Magnetic trapping of molecules via optical loading and magnetic slowing
(2014-02-25)
This thesis demonstrates a new cooling and trap loading technique for molecules, leading to trapping of calcium monofluoride (CaF).
Between Patron and Priest: Amdo Tibet Under Qing Rule, 1792-1911
(2014-02-25)
In the late eighteenth century, a Qing-centered, pluralistic legal order emerged in the Tibetan regions of the Qing empire. In the Gansu borderlands known to Tibetans as "Amdo," the Qing state established subprefectures ...
Banlieue Stories: Mapping the Paris Suburbs On Screen, 1958-2012
(2014-02-25)
The substantive la banlieue does not simply describe a geographical territory, but rather names a particular articulation of images and narratives that constitute the ‘banlieue question’. This dissertation ...
Optics at interfaces: ultra-thin color coatings, perfect absorbers, and metasurfaces
(2014-02-25)
The vast majority of optical components and devices in use today can be grouped under the umbrella of ``bulk optics''; i.e. they generally have a non-negligible thickness compared to the wavelength of light. This is true ...
Political Literacy and the Politics of Eloquence: Ottoman Scribal Community in the Seventeenth Century
(2014-02-25)
In 1703, the chief scribe (reisü'l-küttab) Rami Mehmed Efendi (d. 1708) was appointed as the grand vizier in the Ottoman Empire. In scholarship, Rami Mehmed epitomizes the transition in the political cadres from the people ...
Differential Innate Immune Stimulation Elicited by Adenovirus and Poxvirus Vaccine Vectors
(2014-02-25)
Vaccines are one of the most effective advances in medical science and continue to be developed for applications against infectious diseases, cancers, and autoimmunity. A common strategy for vaccine construction is the use ...
