Semasiography('writing with signs', fromGreeksemasia'signification' +graphia'writing') is the use of symbols, calledsemasiographs, to "communicate information without the necessary intercession of forms of speech". This non-phonetic based technique is studied insemasiologywithin the field oflinguistics. Semasiography ...

Whennis greater than 30, this is a good approximation of results from more sensitive tests. For example, a pa...

Incontrol theory, astate observer,state estimator, orLuenberger observeris a system that provides anestimateof theinternal stateof a given real system, from measurements of theinputand output of the real system. It is typically computer-implemented, and provides the basis of many practical applications. Knowing the s...

Instatistics,sufficiencyis a property of astatisticcomputed on asample datasetin relation to a parametric model of the dataset. A sufficient statistic contains all of the information that the dataset provides about the model parameters. It is closely related to the concepts of anancillary statisticwhich contains no inf...

Protein structure predictionis the inference of the three-dimensional structure of aproteinfrom itsamino acidsequence—that is, the prediction of itssecondaryandtertiary structurefromprimary structure. Structure prediction is different from the inverse problem ofprotein design. Protein structure prediction is one of th...

Aposition weight matrix (PWM), also known as aposition-specific weight matrix (PSWM)orposition-specific scoring matrix (PSSM), is a commonly used representation ofmotifs(patterns) in biological sequences. PWMs are often derived from a set of aligned sequences that are thought to be functionally related and have become...
