Power module heat dissipation with spatial inhomogeneity and induced nonuniform temperature distribution presents a challenging concern for system reliability due to thermo-mechanical stresses. These challenges are especially important nonplanar designs using 3-D packaging principles. Here, we develop spreader thermal switch capable of actively reducing gradients between silicon carbide (SiC) d...

A ten-year-old reconstruction surgery of a total nasal dorsum defect on the right nose involves medial arm flap and self-rib cartilage, complicated into fibrous tissue retraction, which caused nostril narrowing asymmetry. This complication was corrected using combination nasolabial for skin coverage modified, old rib cartilage graft to create supportive rim newly reconstructive ala. There is co...

The purpose of this article is to present a modified ultrasonic spreader and a new technique that are used for the retrieval of solid obstructions that can not be bypassed by conventional methods. The technique advocated and the instruments proposed are described. A clinical case is discussed to show the possibilities and limitations of both instrument and method.

A good rhinoplasty dissection is crucial to identify and release the vectoral forces on a deviated septum before correction. Even after completing the dissection, dorsal hump reduction, septoplasty, and osteotomy, there may be persisting septal deviation. A number of techniques have been identified to correct various kinds of deviations that persist after release. Cartilage grafts from the sept...

Super-spreaders are the nodes of a network that can maximize their impacts on other nodes, e.g., in the case of information spreading or virus propagation. Many centrality measures have been proposed to identify such nodes from a given network. However, it has been observed that the identification accuracy based on those measures is not always satisfactory among different types of networks. In ...

OBJECTIVES This study aims to show the placement of extended spreader grafts in reductive septorhinoplasty operations to support the nasal bony vault as well as the middle cartilaginous structures. PATIENTS AND METHODS Thirty-eight patients (16 males, 22 females; mean age 26.4 years; range 18 to 55 years) who underwent septorhinoplasty under general anesthesia via open approach between Januar...

BACKGROUND According to statistics of American Society of Plastic Surgeons, cosmetic rhinoplasty was the second most frequently performed cosmetic surgery. This study shares the experiences with component rhinoplasty. METHODS From 2004 to 2010, all patients underwent aesthetic nasal surgery were enrolled. The patients requiring only correction of septal deviation and those presenting with cl...
