Design and control of a cellular architecture-based adaptive wiring manifold
… wiring harnesses utilize fixed wiring harness architectures, consisting of either bundles of physical wires, electrical components with backplanes, or motherboard/card arrangements. All such designs are generally configured at manufacture and require significant rework when mission requirements …

Improved pattern growth and reconfiguration methods for a fault- tolerant cellular architecture
… the development of a fault tolerant parallel architecture. The main thrust of this research has been on distributing the control of the parallel architecture through the use of the ideas behind cellular automata. The control has been distributed, because having a single control unit …

A distributed control reconfiguration algorithm for 2-dimensional mesh architectures which tolerates single faults per row
… is developed for 2-dimensional mesh architectures and applied to a fault T tolerant cellular architecture. The reconfiguration is accomplished by adding communications paths to each cell which can be enabled by means of transistor switches controlled by decoding the contents of a …

Scheduling algorithms to improve utilization in toroidal-interconnected systems
BlueGene/L is a massively parallel cellular architecture system with a toroidal inter-connect, currently being developed at the IBM T.J.Watson Research Center. Cellular architectures with a toroidal interconnect are effective at producing highly scalable computing systems, but typically require job …

Mapping the Feeding Circuitry in the Mouse and Human Brain
… with little information about the hypothalamic cellular architecture in humans. Therefore, this thesis aims to map the feeding circuitry in the mouse and human brain, using transcriptomic approaches. To map the mouse hindbrain, we performed single nucleus RNA sequencing on hindbrain samples from …

A Coverage Area Estimation Model for Interference-Limited Non-Line-of-Sight Point-to-Multipoint Fixed Broadband Wireless Communication Systems
… must be based on a point-to-multipoint (PMP) cellular architecture with low base station antennas, thus possessing the ability to operate in true non-line-of-sight (NLOS) conditions. A possible limiting factor for these systems is link degradation due to interference. This thesis presents a …

Actin remodeling in motile cells
… regulated by actin binding proteins that control cellular architecture and movement. Here, we characterize actin remodeling in shear stress stimulated endothelial cells and in actin networks reconstituted with purified proteins. Fluid shear stress stimulation induces endothelial cells to elongate …

Effect of Postmortem Time and Preservation Fluid on the Tensile Material Properties of Bovine Liver Parenchyma
… a negative effect on the material properties and cellular architecture. Overall, this study illustrated that the effects of postmortem liver degradation varied with respect to the preservation fluid, storage time, and storage block size.

Design and application of a cellular, piezoelectric, artificial muscle actuator for biorobotic systems
… in animals. Biological muscles have a unique cellular structure that departs from traditional electromechanical actuators in several ways. A muscle consists of a vast number of muscle fibers and, more fundamentally, sarcomeres that act as cellular units or building blocks. A muscle's output …

Investigating Potential Multi-Protein Complexes Involving Emx2
… these four areas are marked by differences in cellular architecture and gene expression patterns. However, these physical boundaries are not evident during embryonic development of this structure. Rather, the neocortex initially appears uniform across its expanse, with one exception: a handful …

Cell markers for air chamber development in Marchantia polymorpha
… thanks to its small genome and its simple cellular architecture, is an excellent model for the study of developmental processes. Marchantia can propagate asexually producing small flat disc-like propagules, called gemmae, that develop into adult plants. Gemmae have an open mode of …

The dynamics and regulation of actin filaments in vascular endothelial cells and in a reconstituted purified protein system
… Proteins that regulate actin cycling control cellular architecture and movement. One method to measure parameters that characterize actin dynamics is photo activation of fluorescence (PAF), which can simultaneously estimate the fraction of total actin polymerized (PF) and the lifetime of actin …
