Traditional material used for the wire bond has been Au; however, its high cost combined with its susceptibility to reliability failure caused by excessive growth of IMCs (IMC) makes Cu to be an attractive replacement. Though, since an application of Cu to wire bond technology is relatively new, many of reliability failure mechanisms are unknown especially …

A Harmonic Function Method For Eeg Source Reconstruction, Hongguang Xi

Mathematics Dissertations - Archive

Neuronal activities generate the electrical current in the brain, and further result in the potential changes over the scalp. Electroencephalography (EEG) is a technique used to record the potential changes on the scalp. Even though fMRI, PET, MEG and other brain-imaging tools are widely used in brain research, they are limited by low spatial/temporal resolution, cost, mobility and suitability for long-term monitoring. In contrast, EEG signals have been successfully used to obtain useful diagnostic information (neural oscillations and response times) in clinical contexts. Further, they present the advantage to be highly portable, inexpensive, and can be acquired at the bedside …

Zoning’S Centennial: A Complete Account Of The Evolution Of Zoning Into A Robust System Of Land Use Law—1916-2016 (Part Iii), John R. Nolon

Elisabeth Haub School of Law Faculty Publications

In land use, there are two things that Americans dislike: one is sprawl, the other is density. This catch-22 can be resolved by mitigating those aspects of urban living associated with density: congestion, bulky buildings, sameness, design incongruities, unsafe streets, inefficiency, and the sense that neighborhoods are not livable and pleasant. These characteristics of density cut against sustainability. They define places that people want to leave as soon as they can. To reduce vehicle miles travelled and carbon emissions, as well as to prevent sprawl, we must create places of enduring value, located next to transit in walkable and sustainable …

The Impact Of Paroxysmal Sympathetic Hyperactivity Following Traumatic Brain Injury On Intensive Care Unit Length Of Stay And Discharge Disposition., Kimberly S. Meyer

Electronic Theses and Dissertations

Paroxysmal Sympathetic Hyperactivity (PSH) is a complication affecting a subset of patients with severe traumatic brain injury (TBI). It is associated with increased morbidity, longer lengths of stay, and delayed recovery (Perkes, Baguley, Nott, & Menon, 2010). The most prevalent signs and symptoms of PSH include unprovoked tachycardia, tachypnea, hypertension, dystonia, and diaphoresis (Lemke, 2007). If untreated, PSH can lead to impaired cerebral blood flow, sub-endocardial damage, dehydration, malnourishment, and contractures (Lemke, 2007). Results from this retrospective study indicate that there is no difference in intensive unit (ICU) length of stay in TBI patients with PSH compared to those without …

Examination Of The Relevance Of Pi3k And Pten Pathway In Ustilago Maydis., Nathaniel Edward Dalton

Ustilago maydis is a fungal pathogen that is an obligate parasite on Zea mays (Corn) in order to undergo and complete its sexual life cycle. The cells grow as a haploid form until they meet a compatible partner and undergo a dimorphic switch from a budding yeast-like cell type to a filamentous dikaryon. Infection of the host plant is characterized by leaf chlorosis, anthocyanin content, and formation of large galls that develop on the stem, leaves, cobs, and flowers. Many signaling cascades such as MAPK and PKA are involved in the regulation of the infection lifecycle. The Phosphatidylinosotiol 3 Kinase/ …

Identification And Characterization Of Genes Involved In Metabolism Of N5 Monoene Precursors To N5 Anacardic Acids In The Trichomes Of Pelargonium X Hortorum., Richa A. Singhal

Electronic Theses and Dissertations

Unusual monoenoic fatty acids (UMFA’s) and specialized metabolites called anacardic acids (AnAc) are produced in glandular trichomes of Pelargonium ´ hortorum (geranium). The UMFA’s, 16:1^∆11 and 18:1^∆13 are precursors for the synthesis of unsaturated AnAc 22:1n5and 24:1n5 that contribute to pest resistance in geraniums. UMFAs and their derived AnAc metabolites not only provide a useful biological marker that differentiates the biosynthetic pathway for unusual mononenes from the common fatty acids (i.e. stearic, palmitic, oleic, linoleic and linolenic) but also have industrial, medical and agricultural applications. Fatty acid biosynthesis enzymes like acyl carrier proteins (ACPs); thioesterases (TEs) and β-ketoacyl-ACP …
