Genodermatosis is a hereditary skin disease with three inherited modes including single gene inheritance, multiple gene inheritance and chromosome inheritance. [1] There are many different types of genodermatosis; the prevalence of genodermatosis ranges from 1 per 6000 people to 1 per 500,000 people. [2]
[4] [5] [6] Pattern formation is genetically controlled, and often involves each cell in a field sensing and responding to its position along a morphogen gradient, followed by short distance cell-to-cell communication through cell signaling pathways to refine the initial pattern. In this context, a field of cells is the group of cells whose ...
This allows for representing pattern structures, taking into account more complex relationships between attributes than is possible in the case of flat, numerical feature vectors of fixed dimensionality that are used in statistical classification. Syntactic pattern recognition can be used instead of statistical pattern recognition if clear ...
A very common type of prior knowledge in pattern recognition is the invariance of the class (or the output of the classifier) to a transformation of the input pattern. This type of knowledge is referred to as transformation-invariance. The mostly used transformations used in image recognition are: translation; rotation; skewing;
The easiest way to create a classification is to use a template if there is one that is appropriate. See the template section below. If there is no template that will work you can add a classification by manually editing a category to insert links. The classification for Contraltos was created with this text:
This template should be used on organism categories to show the hierarchy of categories in the biological Tree of Life. Only existent categories will be shown. Only existent categories will be shown. For each parameter, enter the name of the category without Category: .
This pattern of development (with a distinct head and tail) is called cephalization. It is also argued that the development of an AP axis is important in locomotion – bilateral symmetry gives the body an intrinsic direction and allows streamlining to reduce drag. In addition to animals, the flowers of some plants also show bilateral symmetry.
de La Dure-Molla, Foruner and Berdal (2015) have proposed a new classification to supersede the Shield Classification (1973). This new classification is designed to overcome the shortcomings of its predecessor, mainly the clinical difficulty in using the Shield classification due to the overlapping signs & symptoms between the sub-types.
