[1] [2] In traditional morphometry, volume of the whole brain or its subparts is measured by drawing regions of interest (ROIs) on images from brain scanning and calculating the volume enclosed. However, this is time consuming and can only provide measures of rather large areas. Smaller differences in volume may be overlooked.
The region of interest for which Markov's inequality gives a lower bound. A region of interest (often abbreviated ROI) is a sample within a data set identified for a particular purpose. [1] The concept of a ROI is commonly used in many application areas. Existing as a vicinity, or within one.
An increase in open interest along with an increase in price is said by proponents of technical analysis [4] to confirm an upward trend. Similarly, an increase in open interest along with a decrease in price confirms a downward trend. An increase or decrease in prices while open interest remains flat or declining may indicate a possible trend ...
Volume analysis is used to confirm and predict price directions. [3] The theory behind volume analysis rests primarily on the assumption that a high trade volume signals market consensus behind the corresponding movement in price, and thus that the trend in price is likely to continue. [ 5 ]
Mathematical and theoretical biology, or biomathematics, is a branch of biology which employs theoretical analysis, mathematical models and abstractions of living organisms to investigate the principles that govern the structure, development and behavior of the systems, as opposed to experimental biology which deals with the conduction of ...
Biological data has also been difficult to define, as bioinformatics is a wide-encompassing field. Further, the question of what constitutes as being a living organism has been contentious, as "alive" represents a nebulous term that encompasses molecular evolution, biological modeling, biophysics, and systems biology.
Ecological analysis of CO 2 in an ecosystem. Systems ecology is an interdisciplinary field of ecology, a subset of Earth system science, that takes a holistic approach to the study of ecological systems, especially ecosystems. [1] [2] [3] Systems ecology can be seen as an application of general systems theory to ecology.
Sequence analysis in molecular biology includes a very wide range of processes: The comparison of sequences to find similarity, often to infer if they are related ( homologous ) Identification of intrinsic features of the sequence such as active sites , post translational modification sites, gene-structures , reading frames , distributions of ...
