This paper introduces a fast infrared spots detection algorithm designed for field-programmable gate array (FPGA) implementation. The proposed algorithm processes four pixels per clock cycle and detects infrared spots in a single pass over a frame. The implementation of the algorithm is only composed of combinatorial logic and registers. Furthermore, the execution time of the algorithm is indep...

To determine the incidence and clinical relevance of active human herpesvirus 6 (HHV-6) infection, 92 consecutive unselected recipients of autologous or allogeneic stem cell grafts were investigated in a prospective longitudinal study. Active infection was assessed by the presence of viral deoxyribonucleic acid (DNA) in 846 peripheral blood mononuclear cell specimens and 115 plasma specimens, b...

When analysing the behavior of complex networked systems, it is often the case that some components within that network are only known to the extent that they belong to one of a set of possible ”implementations” – e.g., versions of a specific protocol, class of schedulers, etc. In this report we augment the specification language considered in BUCSTR-2004-021, BUCS-TR-2005-014, BUCS-TR-2005-015...

Distributional chaos was introduced in Schweizer and Smítal (Trans Am Math Soc 344:737–754, 1994) for continuous maps of the interval, as chaotic behavior based on development distances between orbits points system. In Balibrea et al. (Chaos Solitons Fractals 23(5):1581–1583, 2005), this phenomenon generalized to compact metric space distinguished into three different forms, DC1, DC2 DC3. Loran...

BACKGROUND It is well known that the tobacco industry has placed articles in scientific literature to maintain controversy over the dangers of tobacco use, while claiming that smokers are well-informed about risk. This study illuminates an industry attempt to directly undermine popular understanding of the hazards of smoking using an industry-created organization called Associates for Research ...

Abstract Introduction Many people wish to retain their independence as they age. Therefore, identifying factors that can predict sustainability of for older over time are essential preventing functional decline and maintaining quality life. Method Longitudinal, health, social economic data, from community-dwelling aged ≥75 years (collected at baseline (BL), 6, 12, 24 48 months), were obtained t...
