Retraction fibers (RFs) determine orientation of the cell division axis and guide the spreading of daughter cells. Long and unidirectional RFs, which are especially apparent during mitosis of cells in three-dimensional (3D) environments, enable improved control over cell fate, following division. However, 3D gel environments lack the cues necessary for...
The complexity of designing and testing today's system on chip (SOC) is increasing due to greater integrated circuit (IC) density and higher IO and memory frequencies. SOCs for the mobile phone and tablet market have the unique challenge of short product development windows, at times less than six months, and...
Ultra-wideband (UWB) radio has become an attractive alternative for wireless communications due to the robustness to multipath fading, low power transmission, mostly-digital implementation, and low cost. Furthermore, short-range, high data-rates applications are possible with UWB radios due to the wide spectral
allocations at 3.1 - 10.6 GHz.

High speed serial links are critical components for addressing the growing demand for I/O bandwidth in next-generation computing applications, such as many-core systems, backplane and optical data communications. Due to continued process scaling and circuit innovations, today's CMOS serial link transceivers can achieve tens of Gb/s per pin. However, most...
For the past half century, CMOS process scaling has followed Moore's law, approximately doubling transistor density every 18 months. While locally routed wires have generally scaled with transistor size, longer wires have scaled at a slower rate and in some cases have grown larger as chip size and complexity have...
Biorhythm theory proponents believe that humans have
a 23-day physical cycle, a 28-day emotional cycle, and a
33-day intellectual cycle. According to biorhythm theories
a person in the positive portion of any single cycle, the performance potential is enhanced for those tasks related to
that particular rhythm. When each cycle...
The focus of this thesis involves development of highly transparent, n-channel, accumulation- mode thin-film transistors employing a zinc tin oxide (ZTO) channel layer. ZTO-based transparent thin-film transistors (TTFTs) show improved device performance compared to ZnO-based TTFTs. An estimated peak effective mobility for these devices as high as ~100 cm² V⁻¹sec⁻¹...
The classical chi-square goodness of fit test and the Neyman smooth tests are generalized for arbitrarily right-censored samples. The test statistics are shown to have limiting chi-square distributions under completely specified (simple) null hypotheses and random censorship. Limiting distributions of the generalized chi-square goodness of fit tests are also established...
The problem of footstep level resolution indoor path tracking and gait velocity
lacks a good solution. The current solutions are either prohibitively expensive [4],
extremely invasive to deploy [1], or too inaccurate to achieve the sub meter level
resolution required to track foot paths. By combining existing pedestrian dead
reckoning...
