Biologically inspired detection of circular patterns
2020 10th International Symposium on Signal, Image, Video and Communications (ISIVC), 2021The human visual system (HVS) is particularly efficient to detect and identify specific patterns even if incomplete or occluded. For example the HVS is able to determine a circular configuration in a complex scene by reconstructing non-visible parts of the object under study.

Fluorometric Detection of BiologicalS-Nitrosothiols
Analytical Biochemistry, 1997A technique is presented for the quantitative detection of S-nitrosothiols formed by model biological thiols, cysteine, glutathione, and serum albumin. The technique is based on the detection of fluorescent compound 1-[H]-naphthotriazole formed between 2,3-diaminonaphthalene and nitrous acid released from S-nitrosothiols by treatment with mercuric ...

The use of nanocrystals in biological detection
Nature Biotechnology, 2003In the coming decade, the ability to sense and detect the state of biological systems and living organisms optically, electrically and magnetically will be radically transformed by developments in materials physics and chemistry. The emerging ability to control the patterns of matter on the nanometer length scale can be expected to lead to entirely new

Trends in Biological Detection
2014This chapter shortly summarizes some highlights from the development of modern biodetectors and looks forward in what directions the development is going. The initial expectations may have settled to a more realistic level and biodetectors are now finding their role in different military and security applications. Also biodetectors originally developed

An algorithm for the detection of peaks in biological signals
Computer Programs in Biomedicine, 1982An algorithm based on the theory of maxima and minima is described for the detection of peaks in digitized biological signals. A three-point 'sliding' window is used to identify the peaks, while a threshold window involving a combination of amplitude, slope or duration criterion is employed to eliminate spurious peaks.

Detection of shape changes in biological features *
Journal of Microscopy, 2000The question of analysing shape changes over time, such as during growth and during the progress of disease, is an important fundamental issue for many applications. Recent mathematical developments in the understanding of the detailed structure of shape spaces have made possible the quantitative study of shape variation.

Detection of Structural Features in Biological Signals
Journal of Signal Processing Systems, 2009In this article structures in biological signals are treated. The simpler--directly visible in the signals, which still demand serious methods and algorithms in the feature detection, similarity investigation and classification. The major actions in this domain are of geometric, thus simpler sort, though there are still hard problems related to simple ...

Biological methods for marine toxin detection
Analytical and Bioanalytical Chemistry, 2010The presence of marine toxins in seafood poses a health risk to human consumers which has prompted the regulation of the maximum content of marine toxins in seafood in the legislations of many countries. Most marine toxin groups are detected by animal bioassays worldwide.

A method for the detection of superoxide in biological systems
Archives of Biochemistry and Biophysics, 1982Abstract The ability to detect superoxide in biological milieu is filled with a number of difficult problems. For example, the ferricytochrome c assay method cannot be used in the presence of NADPH-cytochrome P -450 reductase since cytochrome c is preferentially reduced by this enzyme. We have found that the superoxide-dependent oxidation of one
