We present designs, theory and the results of fabrication and testing for a novel parallel microrobotic assembly scheme using stress-engineered MEMS microrobots. The robots are 240-280 μm × 60 μm × 7-20 μm in size, each robot consist of a...
Liver disease of different etiologies confers significant morbidity and mortality and hence it constitutes a major health concern worldwide. Stemming from a range of causes, such as viral, drug-induced, alcoholic, or autoimmune, the rate of...
Light scattering from tissue originates from the fluctuations in intra-cellular and extra-cellular components, so it is possible that macroscopic scattering spectroscopy could be used to quantify sub-microscopic structures. Both electron microscopy...
A mobile agent is an autonomous program that can migrate under its own control from machine to machine in a heterogeneous network. In other words, the program can suspend its execution at an arbitrary point, transport itself to another machine, and...
Many alkaloids of biological importance have the 11H-pyrido (4,3,2-mn) acridine ring structure such as cystodytin and amphimedine. It would be desirable to find an effective way to synthesize a wide variety of these compounds using a single...
Acyl-coenzyme A: cholesterol acyltransferase (ACAT) plays important roles in cellular cholesterol homeostasis and in early stages of atherogenesis. ACAT has been investigated as a pharmaceutical target, yet its active site(s) remain largely...
Traditionally, mast cells have been studied for their role as proinflammatory effector cells in allergic disorders. Recent findings however have opened up the discussion in the community of immunologists regarding MCs should be considered as...
α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs) function as paracrine and autocrine receptors throughout the body. Most studies have focused on their role in fast excitatory neuronal signaling, and learning and memory. In...
Earth's high latitude ionosphere, highly disturbed by particle and energy inputs and associated aurora, is the stage for plasma wave activity across a wide range of frequencies. These waves often exhibit strikingly distinct time-frequency structure...
The opportunistic pathogen Pseudomonas aeruginosa secretes a protein that triggers the accelerated degradation of the cystic fibrosis transmembrane conductance regulator (CFTR) in airway epithelial cells. This protein, known as the CFTR inhibitory...

Spatial heterogeneity inherent in ecological systems impacts both diversity and community structure. However, little is known about the influence of habitat heterogeneity on temporal variability in communities. I performed several studies to...
Strong evidence exists showing that stellar evolution models are unable to accurately predict the fundamental properties of low-mass stars. Observations of low-mass stars in detached eclipsing binaries (DEBs) indicate that stellar models...
This thesis presents technologies for the design, fabrication, operation, and control of electrostatic MEMS micro-robots. It describes prototype micro-robots, with dimensions of 60 μm by 250 μm by 10 μm, that are capable of controllable...
Free electron lasers. ; Cherenkov radiation. ; Far infrared lasers. ; Lasers -- Resonators.
In the far infrared region of the electromagnetic spectrum, 15-3000 μm in wavelength, there is a lack of narrow band sources. The Cerenkov free electron laser (CFEL) shows promise to fill this gap. The Cerenkov resonator was analyzed theoretically...
