Cell Size Control in Fission Yeast
… organisms, there is almost much variety in cell size as there is for cell function and cell type. However, within each cell type, cells stay remarkably faithful to a defined size over generations. Many factors have been found to influence this ability to specify and maintain cell size, yet clear …

The Hippo Signaling Pathway in Organ Size Control and Regeneraton
The Hippo (Hpo) signaling pathway controls cell growth, proliferation and apoptosis in both Drosophila and vertebrates. Our lab has previously demonstrated that Hpo signaling regulates gene expression by inhibiting a transcription complex consisting of the transcriptional coactivator Yorkie (Yki) …

Self-Assembly, Spatial-, and Size- Control of Gold Nanoparticle/Block Copolymer Conjugates
… with different block lengths of 4VP were synthesized via sequential living anionic polymerization. Two different approaches of functionalized AuNP with S4VP polymers were exposed. Pyridylterminated polystyrenes were employed as monodentate ligands for AuNP, while longer blocks of 4VP were used …

Tackling the Bottlenecks in Translational Nanomedicine: Towards Precision in Size Control and Facile Nanoformulation
… that include low targeting efficiency, imprecise size control, lack of scalable fabrication, rigorous stability requirement, and complicated manufacturing process. The common focus of the studies here is to address these bottlenecks by developing novel nanoparticle systems which are better …

Cell Size Control And Asymmetric Cell Fates In Start Of The Saccharomyces cerevisiae Cell Cycle
… called Start, requires growth to a critical cell size. This deterministic model did not address how cell size control can be achieved despite the stochasticity of elementary cellular processes. Furthermore, no clear connection between the commitment at Start and the molecular network controlling …

A study of revenues and expenditures in community colleges grouped by size, control, and curricular balance
… of three pertinent characteristics (size, control, and curricular balance) to the distribution of revenues by source and expenditures by function in community colleges. It was hypothesized that there would be no statistically significant differences among community colleges grouped by …

High precision mass-based assay to examine growth regulation of the cell cycle
… and regulation of cell cycle processes. Though size is considered to be a fundamental property of cell state, its measurement on a single-cell basis with high-resolution has been elusive primarily due to enormous experimental barriers. This thesis discusses the use of a cantilever based …

Development of Novel Synthetic Methods for Size-Tunable Synthesis of Superparamagnetic Iron Oxide Nanoparticles
… of magnetic nanoparticles vary dramatically with size, so reproducibly controlling size is critical for practical applications. This is particularly true when moving into clinical settings, where regulatory approval requires demonstrated reproducibility in efficacy that can only be achieved with …

Methods for nano-precise overlay in advanced in pick-and-place assembly
… J-FIL currently uses template shape-and-size control, along with x-y-q substrate position control, to overlay template patterns to substrate patterns. This method is designed to mix-and-match with photolithography (PL) and corrects distortions over a limited field size of 26mm x 33mm. …

Interactions Between Supersonic Gas Jets and Gas-Solid Fluidized Beds
… green sand reclamation and particle size control in fluid cokers. These two applications make use of the same attrition principles, and the main difference between them is that for green sand reclamation fragmentation is not desired, since its goal is just to remove an outer layer of …
