Highly pathogenic (HP) H5N1 avian influenza (AI) is enzootic in several countries of Asia and Africa and constitutes a major threat, at the world level, for both animal and public health. Ducks play an important role in the epidemiology of AI, including HP H5N1 AI. Although vaccination can be a useful tool to control AI, duck vaccination has not proved very efficient in the field, indicating a ...

This paper analyzes the provision of end-to-end Quality of Service between nodes in a mobile ad hoc network and a fixed IP network that supports Differentiated Services. The ad hoc network incorporates the Stateless Wireless Ad Hoc Networks (SWAN) model to perform admission control for real-time traffic flows. We propose a new protocol, named DS-SWAN (Differentiated Services-SWAN), where end-to...

We define a numerical invariant, the differential Swan conductor, for certain differential modules on a rigid analytic annulus over a p-adic field. This gives a definition of a conductor for p-adic Galois representations with finite local monodromy over an equal characteristic discretely valued field, which agrees with the usual Swan conductor when the residue field is perfect.

Complications from Swan-Ganz catheters during insertion, long-term placement, or removal have been known since its development. I describe the unusual presentation of a pacing Swan-Ganz catheter mispositioned into the hepatic vein producing vascular obstruction, yet with adequate cardiac pacing.

Dear Editor, Pulmonary artery catheter is widely used in cardiovascular surgical practice. Various complications of the Swan-Ganz catheter during insertion, its long-term placement, or removal are well known since its introduction.1-5 Herein, we report a case of the inadvertent fracture of an entrapped Swan-Ganz catheter during its attempted removal with moderate external traction. A 36-year-ol...

Aims. The DQ white dwarfs are stars whose atmosphere is enriched with carbon, which for cool stars (Teff < 8000 K) is indicated by the Swan bands of C2 in the optical part of their spectra. With decreasing effective temperature these molecular bands undergo a significant blueshift (∼100–300 Å). The origin of this phenomenon has been disputed over the last two decades and has remained unknown. W...

The non-abelian tensor product of groups which has its origins in algebraic K-theory as well as inhomotopy theory, was introduced by Brown and Loday in 1987. Group theoretical aspects of non-abelian tensor products have been studied extensively. In particular, some studies focused on the relationship between the exponent of a group and exponent of its tensor square. On the other hand, com...

Most literature searching in biomedicine is now conducted via PubMed, Google Scholar or other web-based bibliographic search mechanisms. Yet until now a public, open, interoperable and complete web-adapted information schema for bibliographic citations, bibliographic references and scientific discourse has not been available. Such a schema, expressed in the form of a description logic compatibl...
