In cellular systems there is usually an overlap cell coverage area (area covered by two or more base stations) which has valuable practical applications. Particularly, it permits the queuing of handover requests as a handover prioritization scheme. The modeling of the sojourn time in the overlap area is a topic which is not sufficiently explored, and even less is the effect it may have on the p...

Transcription typing is one of the basic visual-motor control tasks with practical importance. Brain imaging studies (fMRI and PET) have discovered 2 phenomena related to transcription typing, involving different activation patterns of brain areas. In behavioral studies, Salthouse (1986) summarized 29 quantitative behavioral phenomena of transcription typing, 19 of which were modeled by TYPIST ...

Queuing theory provides a theoretical framework for quantitative understanding of the performance of streaming applications. There are questions, however, as to the suitability of queuing models to real applications. Here, we investigate the correspondence between a relatively simple queuing model of an FPGA-accelerated BLAST implementation and empirical measurements taken from executions of th...

In recent years, the rapid progress of hardware technology has enabled people to use mobile terminals away from the ofice or home with the use of cellular phones. However there are not a little remaining issues which are narrow bandwidth of wireless communications, the limited battery duration of mobile terminals, and others. This paper proposes a common memory management mechanism for mobile t...

AIMS To produce and characterise a monoclonal antibody specific for O-acetylated sialomucin and to assess its use in immunohistochemistry on a panel of normal and diseased intestinal tissue samples. METHODS Mouse monoclonal antibodies were developed following immunisation with highly purified human colonic mucin. One of these (MMM-17) showed strong binding to mucin throughout the normal colon...

The proliferation of cells in culture requires the presence of growth factors in the medium, provided either by serum or purified proteins. Cells are made quiescent by contact inhibition and sharply diminishing the concentration of growth factors overnight; they are then stimulated by restoring the original high concentration of the growth factors. The addition activates a coordinated group of ...

Accurate modeling of queueing dynamics is important in the design and analysis of Internet congestion control. However, as demonstrated in this paper, existing window-based queueing models [26,30] are often not capable of precisely capturing the transient behavior (i.e., self-clocking and burstiness) of TCP-like protocols and their resulting analysis may be inaccurate in practice. As one exampl...

Available bandwidth is an important factor that can be used to adapt the sending rate to network conditions, so that packet loss, caused by congestion, can be significantly reduced before error control mechanisms are employed. To this end, we propose an active probing-based queuing delay propagation model (QDPM)-based scheme for available bandwidth estimation. Common assumptions, including use ...

The technique of metal magnetic memory (MMM) has great advantages in detecting early failures such as stress concentration and fatigue damage of ferromagnetic components, which has been widely applied due to its high efficiency, low requirements for surface preparation and ease of operation. However, research into the quantitative description of defect characteristics is still far from adequate...
