(2019-08-01)Department: Chemical EngineeringTriple negative breast cancer (TNBC) is an aggressive subtype of breast cancer that lacks estrogen receptor, progesterone receptor, and HER2, making it difficult to treat with conventional medicine. One common form of ...
-
(2018-08-23)Department: Electrical EngineeringThe effects of ionizing radiation and displacement damage are two significant reliability concerns for transducer applications in radiation environments. Microelectromechanical systems (MEMS) are considered as potential ...
-
(2016-08-15)Department: Electrical EngineeringThe total ionizing dose (TID) response of HfO2-SiO2/SiGe pMOS FinFETs under different irradiation biases has been evaluated. Negative bias irradiation leads to the worst-case degradation. We attribute this result to an ...
-
(2012-04-09)Department: Electrical EngineeringSince their discovery, phosphors have been studied extensively and have pervaded our everyday lives. Despite the wealth of research conducted on phosphor powders there has been no research published on long-term effects ...
-
(2013-07-05)Department: Electrical EngineeringGallium Nitride (GaN)-based devices are used in space-based high power, high frequency applications due to high breakdown voltage and high carrier mobility and the large bandgap of GaN. The radiation effects and hot carrier ...
-
(2016-07-27)Department: Electrical EngineeringIn recent years, GaN-based high-electron-mobility-transistors (HEMT) have demonstrated excellent high power and high frequency performance compared with counterparts based on other materials. Although AlGaN/GaN HEMTs are ...
-
(2011-09-02)Department: Electrical EngineeringThe effects of low and medium energy x-rays on MOS capacitors with SiO2 or HfO2 gate dielectrics and Al and TaSi gate metallization have been studied using the Monte Carlo simulator, MRED. We find good agreement between ...
-
(2007-04-14)Department: Biomedical EngineeringThe objective of this study was to image tumor-targeting using a single chain fragment variable antibody to radiation-induced P-selectin in a heterotopic Lewis lung carcinoma model by near-infrared fluorescence imaging and ...
-
(2010-04-16)Department: Electrical EngineeringSingle-event transients (SETs) due to terrestrial or space radiation exposure have become a growing concern in modern high-speed data acquisition systems and space deployed electronics. Therefore the single-event vulnerability ...
-
(2012-08-06)Department: PhysicsRecent advances in radiation biology have caused a shift in focus from the classical view of direct DNA damage and repair to one that encompasses intricate cellular signaling pathways present at both the cell and tissue ...
-
(2008-04-28)Department: Interdisciplinary Materials ScienceThis dissertation presents the radiation-induced charge trapping studies of upcoming material systems of Si and SiC for future low power and high power technologies. HfO2/Si with metal gates has already been announced as ...
-
(2005-12-16)Department: Electrical EngineeringEnergy deposition from particles in space can cause upsets in microelectronic devices resulting in unreliable systems. A Geant4 based application, MRED (Monte Carlo Radiative Energy Deposition), is used to investigate ...
-
(2010-04-20)Department: Political ScienceIn this project, I examine Chantal Mouffe’s agonistic pluralism as a model for radical democracy. In so doing, I focus upon Mouffe’s simultaneous emphasis on liberalism as a necessary condition for the possibility of radical ...
-
(2007-12-13)Department: ChemistryProtein identification generally involves enzymatic digestion of proteins followed by mass spectrometry (MS) sequencing analysis of the resulting peptides, a process referred to as bottom-up proteomics. Another approach ...
-
(2012-12-20)Department: ReligionUntil 1990, most black and progressive churches in Namibia were proponents of a contextual variant of liberation theology. In it, Black churches and liberationists who were bound together by suffering, oppression, and ...
