Cotton (Gossypium hirsutum L.) fibers are derived from ovule epidermis, which are developmentally similar to Arabidopsis trichome where several MYB transcription factors have been shown to control their formation. However, little is known about the molecular control of cotton fiber initiation. Here we isolated 55 cotton MYB domain-containing sequences(More)
Cotton (Gossypium hirsutum L.) fibers are single highly elongated cells derived from the outer epidermis of ovules. A large number of genes are required for fiber differentiation and development, but so far, little is known about how these genes control and regulate the process of fiber development. Here we examine the role of the cotton-fiber-specific R2R3(More)
We describe matrix computations available in the cluster programming framework, Apache Spark. Out of the box, Spark provides abstractions and implementations for distributed matrices and optimization routines using these matrices. When translating single-node algorithms to run on a distributed cluster, we observe that often a simple idea is enough:(More)
We propose a new formulation called hyperedge expansion (HE) for hypergraph learning. The HE expansion transforms the hypergraph into a directed graph on the hyperedge level. Compared to the existing works (e.g. star expansion or normalized hypergraph cut), the learning results with HE expansion would be less sensitive to the vertex distribution among(More)
Autologous fat grafting is an exciting part of plastic and reconstructive surgery. Fat serves as a filler and its role in tissue regeneration will likely play a more important role in our specialty. As we learn more about the basic science of fat grafting and the standardized techniques and instruments used for fat grafting, this procedure alone or in(More)
BACKGROUND The viability of fat grafts obtained by even a well-established technique remains poorly studied and unknown. This study was designed to determine the viability of fat grafts harvested and refined by the Coleman technique. METHODS Sixteen adult white women were enrolled in this study. In group 1 (n = 8), fat grafts were harvested and processed(More)
BACKGROUND Autologous fat transplantation has frequently been used by many surgeons for facial recontouring in esthetic patients, with good long-term results. However, this technique has not been used primarily in treating patients with hemifacial atrophy, and its efficacy and long-term outcome remain unknown. METHODS In a 7-year period, 31 patients with(More)
This study was conducted to evaluate the viability of fatty tissues within adipose aspirates after conventional liposuction and to examine their potential role as a source of donor material for possible future autogenous fat grafting. Samples of adipose aspirates (group I, n = 8) were obtained from adult female patients who underwent a conventional(More)
BACKGROUND Recent anatomical findings have suggested that facial fat distribution is complex and changes with age. Here, the authors developed a grafting technique based on the physiologic distribution and volume changes of facial fat compartments to achieve a youthful and natural-appearing face. METHODS Forty cadaveric hemifaces were used for the(More)
