OBJECTIVE To determine the incidence of postoperative rotation of flattened hydroxyapatite enucleation implants. METHODS A retrospective review of patients receiving flattened hydroxyapatite enucleation implants was performed to determine the incidence and severity of postoperative implant misalignment. RESULTS Flattened hydroxyapatite implants had been placed in 16 patients. Five were note...

In this paper we present designs of fibers having non-zero positive, non-zero negative and near-zero ultra-flattened dispersion with small dispersion slope and ultra-large effective area over a wide spectral range. The designs consist of a concentric multilayer segmented core followed by a trench assisted cladding and a thin secondary core. The central segmented core helps in maintaining desire...

The Indirect Tension Test (IDT) is frequently used for evaluation of asphalt material viscoelastic creep properties. With the increased use of finer aggregate gradations and polymer modified asphalt binders in asphalt materials, crushing can occur under the narrow loading heads. The new specimen configuration proposed has a trimmed area under the loading heads, creating a “flattened-IDT.” This ...

In the seL4 microkernel and other capability-based OSs, the right to use resources is managed using abstract capabilities (i.e., tokens). Capability systems for fungible resources such as memory are well understood, but it has proven difficult to integrate time—i.e., real-time scheduling—into this model, since timeliness (i.e., system-wide schedulability) is a property that is inherently diffic...

It has previously been shown that a soft mattress lessens the degree of head flattening that occurs in preterm infants in the early weeks of life. A follow up study of 31 infants of < 32 weeks' gestation found head flattening had resolved by 3-4 years of age, regardless of the type of mattress used in the neonatal period, and the children had heads similar in shape to full term controls.
