Annular pancreas is a relatively rare congenital diseasecaused by an embryologica1and anatomical disturbance in pancreas It may have no sympforns throughout the life and so occasionally discovered during an unrelevant surgery or autopsy but in most of the cases it shows itself as a duodenal obstruction during the in­fancy and childhood.Very rarely symptoms of the disease my be obser­ved in adul...

BACKGROUND Lymph nodes (LNs) are positioned strategically throughout the body as critical mediators of lymph filtration and immune response. Lymph carries cytokines, antigens, and cells to the downstream LNs, and their effective delivery to the correct location within the LN directly impacts the quality and quantity of immune response. Despite the importance of this system, the flow patterns in...

Current wireless sensor network routing protocols are still struggling to find valid paths between source and destination, and multipath routing for fault tolerance is quite a new research area and studied insufficiently. The multipath routing techniques designed for ad hoc network do not apply to the sensor network due to the lack of global ID in sensor networks. In this paper, we propose a no...

We present the implementation of a type inference algorithm for untyped object-oriented programs with inheritance, assignments, and late binding. The algorithm signiicantly improves our previous one, presented at OOPSLA'91, since it can handle collection classes, such as List, in a useful way. Also, the complexity has been dramatically improved, from exponential time to low polynomial time. The...

Design-for-testability is a very important issue in software engineering. It becomes crucial in the case of OO designs where control flows are generally not hierarchical, but are diffuse and distributed over the whole architecture. We introduce the concept of a "testing conflict" when potentially concurrent client/supplier relationships between the same classes along different paths exist in a ...

Eleven new quaternary rare-earth tellurides, CsLnZnTe3 (Ln=La, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, and Y), were prepared from solid-state reactions at 1123 K. These isostructural materials crystallize in the layered KZrCuS3 structure type in the orthorhombic space group Cmcm. The structure is composed of LnTe6 octahedra and ZnTe4 tetrahedra that share edges to form [LnZnTe3] layers. These layer...
