It is just the specificity principle! over the last couple of years, i have been writing detailed articles and posting up studies that clarify the different ways in which strength training.
The sensitivity and specificity of a quantitative test are dependent on the cut-off value above or below which the test is positive. In general, the higher the sensitivity, the lower the specificity, and vice versa. Receiver operator characteristic curves are a plot of false positives against true positives for all cut-off values.
Sensitivity and specificity of multiple tests is a common statistical problem in radiology because frequently two tests (a and b) with different sensitivities and specificities are combined to diagnose a particular disease or condition.
Specificity has to do with the specific responses that occur as a result of training. In order for long-term physiological changes or adaptations to occur, a repeated, or chronic, stimuli must be applied to the body, along with progressive overload.

Sensitivity and specificity analysis is used to assess the performance of a test. In medicine it can be used to evaluate the efficiency of a test used to diagnose a disease or in quality control to detect the presence of a defect in a manufactured product.
In composition, specificity refers to words that are concrete and particular rather than general, abstract, or vague. In composition, words that are concrete and particular rather than general, abstract, or vague.

The specificity of immune reactions was initially demonstrated with reactions of serum from ag-injected animals with ags in the form of pathogenic bacteria and their toxic culture filtrates and soon thereafter with a great variety of other ags, including plant proteins, red blood cells, milk, and ovalbumin, for example.
Many proteins select from a small repertoire of 3-dimensional folds retained over evolutional timescales and recruited for different functions, with changes in local structure and sequence to enable specificity.
March 11, 2013 posted by samanthi the key difference between sensitivity and specificity is that sensitivity measures the probability of actual positives, while specificity measures the probability of actual negatives. Sensitivity and specificity are two terms we come across in statistical testing.
Diagnostic accuracy (sensitivity and specificity) of magnetic resonance spectroscopy as an imaging tool in the differentiation of benign versus malignant.

The term the term differential pressure refers to fluid force per unit, measured in pounds per square inch (psi) or a similar unit subtracted from a higher level of force per unit.
Nowadays i work for a medical device company where in a medical test the big indicators of success are specificity and sensitivity. Imagine my surprise today when i found out that other fields use different metrics for the exact same problem.
The sensitivity of a test is the percentage of results that will be correctly positive when hiv is actually present. Lower rates of sensitivity will produce more false negative results. The specificity of a test is the percentage of results that will be correctly negative when hiv is not present.
There are lots of factors that combine to describe how valid a test is: sensitivity and specificity are two such factors. We often think of sensitivity and specificity as being ways to indicate the accuracy of the test or measure. In the clinical setting, screening is used to decide which patients are more likely to have a condition.

Patterson concreteness, (42) or specificity, involves the use of specific and concrete terminology, rather than general or abstract terminology, in the discussion of feelings, experiences, and behavior. It leads to differentiation of feelings and experiences rather.

The specificity of a is 1 (one element) the specificity of b is 101 (one id reference and one element) the specificity of c is 1000 (inline styling) since 1 101 1000, the third rule (c) has a greater level of specificity, and therefore will be applied.
A high-specificity test will correctly rule out almost everyone who doesn’t have the disease and won’t generate many false-positive results.
Specificity of enzymes one of the properties of enzymes that makes them so important as diagnostic and research tools is the specificity they exhibit relative to the reactions they catalyze. A few enzymes exhibit absolute specificity; that is, they will catalyze only one particular reaction.
Replacing a differential carrier, changing bearings or a ring and pinion can be a challenging process. Adjusting it to just right for a long life and quiet operation is the most difficult part of the repair.
The specificity tells us how likely the test is to come back negative in someone who does not have the characteristic. Among all people without the characteristic, what proportion will test negative? 90% of specificity is pretty good.
Specificity is how the test performs in people who are known to not have disease. Highly specific tests tend to be negative in patients without disease. This parameter also depends on the underlying biology of the disease and characteristics of the test.
The transforming growth factor–β (tgf-β) family of secreted proteins is implicated in the control of widely diverse physiologies and its dysregulation with disease. In this review, which contains 7 figures and 343 references, we describe the exquisite nature of tgf-β family signaling in its roles in diverse and context-specific cellular behaviors.
Sensitivity and specificity of case definitions may vary according to the purpose of the case identification. For a severe disease with epidemic potential like sars or ebola haemorrhagic fever, epidemiologists will choose to use first a very sensitive case definition to cast a wide net: they want to avoid missing cases that can further spread the disease.
The specificity at line b is 100% because the number of false positives is zero at that line, meaning all the negative test results are true negatives. The middle solid line in both figures that show the level of sensitivity and specificity is the test cutoff point.
Using stem cell differentiation models to verify antibody specificity.
From a scientific point of view, the method with the highest sensitivity and specificity should be used as diagnostic test. Although real-time pcr has a very good sensitivity and the highest specificity among the 3 tests used, this method is only partially suitable for application in the field.
The specificity of enzymes for their substrate is absolute specificity. Enzymes not only show absolute specificity for their substrate but also for the type of reaction they catalyze. For example, the β-1,4-glycosidic linkage of lactose can only be hydrolyzed by lactase enzyme and this reaction yields glucose and galactose.
21 jan 2011 the degree of metal binding specificity in metalloproteins such as metallothioneins (mts) can be crucial for their functional accuracy.
The blog explains what we mean by - and how to calculate - 'sensitivity', 'specificity', 'positive predictive value' and 'negative predictive value' in the context of diagnosing disease. The diagnostic process is a crucial part of medical practice.

Protein - protein - the specificity of enzymes: since the substrate must fit into the active site of the enzyme before catalysis can occur, only properly designed molecules can serve as substrates for a specific enzyme; in many cases, an enzyme will react with only one naturally occurring molecule.
Specificity is the proportion of truly nondiseased persons who are so identified by the screening test. It is a measure of the probability of correctly identifying a nondiseased person. Successful application of sensitivity and specificity is an important part of practicing evidence-based medicine.

The two graphs again illustrate that sensitivity and specificity are complementary. As the proportion infected in the population at large goes up, one part of the test improves and the other degrades. The moral is this: sensitivity and specificity are intrinsic features of the tests, but interpreting them depends strongly on the environment.
