Ultrasound Studies of Caesarean Hysterotomy Scars
… a caesarean delivery were found to have a large defect. The proportion of women with large scar defects increased with the number of caesarean deliveries (14% in women after one caesarean compared with 21% after two caesareans, and 46% in those who had undergone three or more caesareans; …

Engineered [beta]TCP-binding HER-family protein fusions and their use for improving osteoprogenitor- mediated bone regeneration
… has been shown to aid in the healing of bone defects since the 1950s. Transplantation of freshly-aspirated autologous bone marrow, together with a scaffold, is a promising clinical alternative to harvest and transplantation of autologous bone for treatment of large defects. However, survival …

TOWARDS PERSONALIZED BONE TISSUE ENGINEERING: CLINICALLY INSPIRED APPLICATION OF 3D BIOPRINTING
… for treatment of bone injuries resulting in bony defects are still needed. Autologous bone grafts remain the standard treatment for segmental defects and non-unions. Engineered bone graft substitutes have failed to promote sufficient bone formation in large defects. The work presented here aims to …

Application of RMT-RNN improved decomposition onto defected system
… Theory coupled with Neural Networks (RMT-RNN) to large static systems with relatively large disorder in mesoscopic systems. It is a new algorithm that can quickly decompose random matrices with real eigenvalues for further study of physical properties, such as transmission probability, …

Polymer-tethered epidermal growth factor as an inductive biomaterial surface for connective tissue progenitors
… envisioned applications of CTP, such as treating large defects in bone, involve in vivo implantation of CTP attached to a scaffold, a process that creates an acute inflammatory environment that may be hostile to CTP survival. This project entails the design of a two-component polymeric implant …

STANDARDS TO CONTROL FRACTURE IN STEEL BRIDGES THROUGH THE USE OF HIGH-TOUGHNESS STEEL AND RATIONAL INSPECTION INTERVALS
… study. Results from this research demonstrate large defects are well-tolerated by high-toughness steel. Further, rational inspection intervals were calculated to demonstrate how an integrated FCP will allow for a better allocation of owner resources while also leading to increased steel bridge …

Characterization of the early stages of long bone regeneration in fractures and critical size defects in Xenopus Laevis
… or cancer irradiation can cause critical sized defects in long bones. Regeneration capabilities of most mammals in their long bones are robust in small defects such as fractures but diminish in large defects due to lack of proper cellular cues. A small animal in vivo model has been developed to …

Dual-Use Strain Sensors for Simultaneous Strain Measurement and Acoustic Source Location
… or X-ray inspections where visual inspections, large defects, and high levels of user experience are required. The ultrathin silicon membrane (USM) sensor developed by NanoSonic Inc. is a piezoresistive sensor, incorporating the best aspects of a conventional strain gauge and ultrasonic …

Macro- and micro-structural features direct bone regeneration in patterned biphasic calcium phosphate scaffolds
… for bone repair solutions for the treatment of large and load-bearing bone defects calls for the development of efficacious bone scaffolds. The design of such scaffolds involves a range of length scales from the centimeter down to the micron-scale. Biphasic calcium phosphate (BCP) scaffolds with …

Impulse breakdown characteristics of SF6 and its mixtures in highly non-uniform field gaps
… deposited on the surface of an insulator. Such defects can result in very low breakdown levels and, with large defects (e.g. particles several mm long), failure can occur even at the working stress of the equipment. The breakdown characteristics of gases in nonuniform fields, however, are much …

THE MANY FACES OF REGENERATION: ENGINEERING MULTIFUNCTIONAL SCAFFOLDS FOR CRANIOMAXILLOFACIAL APPLICATIONS
… jaw where bone is missing. People affected by large mandibular defects face consequences that go far beyond esthetics. For example, they often struggle to chew or speak, and this can affect daily life and overall well-being. Mandibular defects can arise from congenital conditions, accidents or, …

Metal oxides as buffer layers in polycrystalline CdTe thin-film solar cells
… ZnO, MgO, and the ternary alloy MgxZn1-xO have large optical band-gaps making them transparent to most of the solar spectrum and an ideal emitter layer adjacent to light-facing side of the absorber in a superstrate configuration. The optical and electrical properties of MgxZn1-xO emitters can be …

The effect of scaffold structure and biologic factors on bone regeneration in cap-based scaffolds measured using machine learning
… conduits are necessary in critically large defects. Hydroxyapatite (HAp) scaffolds are osteoconductive, synthetic grafts that provide an alternative to natural grafts, which have limitations. We and others have fabricated HAp scaffolds with a hierarchical structure that has macropores …
