Lateral disk herniation into the intervertebral foramen if not recognized may result in a negative surgical exploration. The condition is readily recognized by computed tomography (CT), which demonstrates a soft-tissue mass in the intervertebral foramen, focal protrusion of the posterolateral margin of the disk into the foramen, absence of dural sac deformity, and occasionally the presence of c...

A case of vaginally delivered stillborn female thoracopagus conjoined twins is presented. Each twlin had a cleft lip and cleft palate. They shared a common pericardial sac and a common abdominal cavity. The liver was conjoined, and the small bowel was common to both twins. One twin was asplenic. Although the twins were monozygotic, their viscera were neither identical nor mirror-image to each o...

Fusion of embryos or larvae prior to metamorphosis is rarely known to date in colonial marine organisms. Here, we document for the first time that the embryos of the broadcast spawning coral Platygyra daedalea could fuse during blastulation and further develop into conjoined larvae, and the settlement of conjoined larvae immediately resulted in inborn juvenile colonies. Fusion of embryos might ...

This research is concerned with the performance behavior of conjoined supply chains, which typically arise in web-based retail. In particular, five performance measures, belonging to three performance measure classes, are used to study the performance effects of various operational factors on conjoined supply chains. The study is accomplished via experimental design and simulation analysis, and...

Networks can be used to represent syntactic trees of the semantic relations that hold between words in sentences. They can be alternately symbolized as association l i s t s or conjoined sets of t r i p les . A semantic net represents a sentence as a conjoined set of binary predicates. An algorithm is presented that converts a semantic network into predicate calculus formalism. The simpler synt...
