Cases of fractured mobile unicompartmental knee bearings have recently been reported. The purpose of this study was to understand the mechanics behind these fractures and to examine the influence of different design modifications. A parametric finite element model was used to examine the influence of different geometrical factors on the stresses within the bearing. Crack initiation occurred cli...

BACKGROUND The purpose of this study was to determine flap parameter accuracy, extent of the opaque bubble layer, and incidence of skip lines in femtosecond laser-assisted stromal in situ keratomileusis (LASIK) using the WaveLight(®) FS200 laser and optoelectronic clinical measurements. METHODS Images from 101 flaps were automatically recorded during consecutive routine LASIK procedures perfo...

Code obfuscation is a relatively new technique of software protection and it works by deterring reverse engineering attempts by malicious users of software. The objective of obfuscation is to make the logic embedded in code incomprehensible to automated program analysis tools used by adversaries. Opaque predicates act as tool for obfuscating control flow logic embedded within code. In this posi...

Recently, improving eating quality and processing properties has become one of the most important objectives in japonica rice breeding programs in Korea. This study was carried out to determine the agronomy and physicochemical characteristics of the opaque endosperm rice “S-21-3-8” regenerated from seed-derived callus culture of a rice cultivar, “Ilpum”. S3 generation of opaque endosperm mutant...

Algebraic data types and catamorphisms (folds) play a central role in functional programming as they allow programmers to define recursive data structures and operations on them uniformly by structural recursion. Likewise, in object-oriented (OO) programming, recursive hierarchies of object types with virtual methods play a central role for the same reason. There is a semantical correspondence ...

Exploring intentionality from an externalist perspective, I distinguish three kinds of intentionality in the case of seeing, which I call transparent, translucent, and opaque respectively. I then extend the distinction from seeing to knowing, and then to believing. Having explicated the three-fold distinction, I then critically explore some important consequences that follow from granting that ...

The arrival of best-effort hardware transactional memory (TM) creates a challenge for designers of transactional memory runtime libraries. On the one hand, using hardware TM can dramatically reduce the latency of transactions. On the other, it is critical to create a fall-back path to handle the cases where hardware TM cannot complete a transaction, and this path ought to be scalable and reason...

Neisseria gonorrhoeae is naturally competent for DNA transformation. Under most conditions encountered in vivo, gonococci express one or more opacity (Opa) proteins on their surfaces. Recently, it was shown that DNA preferentially binds to the surfaces of Opa-expressing organisms compared to those of isogenic Opa-negative strains, presumably due to the numerous cationic residues in the predicte...

This paper proposes a new design of overlayable transmissive color marker. Each marker is transparent and the marker has different colors, and outside of the marker is a region for estimating order of the overlay. ID patterns are detected from overlaid markers by splitting an input image in red, green and blue channel image. The overlaid order is estimated with the use of average color in the e...
