	Sensitivity (tests) - Wikipedia, the free encyclopedia
		The sensitivity of a binary classification test or algorithm, such as a blood test to determine if a person has a certain disease, or an automated system to detect faulty products in a factory, is a parameter that expresses something about the test's performance.
		Sensitivity alone does not tell us all about the test, because a 100% sensitivity can be trivially achieved by labeling all test cases positive.
		In the traditional language of statistical hypothesis testing, the sensitivity of a test is called the statistical power of the test, although the word power in that context has a more general usage that is not applicable in the present context.

	AGD - Why Are My Teeth Sensitive?
		Tooth sensitivity is caused by the stimulation of cells within tiny tubes located in the dentin (the layer of tissue found beneath the hard enamel that contains the inner pulp).
		Sensitivity may be defined as a short sharp pain, which is usually initiated by hot or cold foods or exposure to cold air.
		Toothpastes for sensitive teeth usually contain a desensitizing agent that protects the exposed dentin by blocking the tubes in the teeth that are connected to nerves.

	Sensitivity (ISO): Digital Imaging: Glossary: Learn: Digital Photography Review
		The lower the sensitivity, the finer the grain, but more light is needed.
		This is excellent for outdoor photography, but for low-light conditions or action photography (where fast shutterspeeds are needed), more sensitive or "fast" film is used which is more "grainy".
		When increasing the sensitivity, the output of the sensor is amplified, so less light is needed.

	Finer Health and Nutrition : Educational Information : Frequently Asked Questions about Gluten Sensitivity
		Gluten sensitivity implies that there is an ongoing immune reaction to gluten in the diet, usually detected as antibodies against a subprotein of gluten called gliadin.
		In recent years, testing for gluten sensitivity and celiac sprue usually is initiated with blood tests for antibodies against gliadin, the toxic subfraction of wheat gluten, or for an antiendomysial antibody that is produced against an enzyme present in the intestine and elsewhere in the body called tissue transglutaminase.
		In such people, gluten sensitivity is still possible but the probability (or in other words the chances or the odds) is lower than in a person who may be having symptoms attributable to gluten or that has antibodies detected.

	Michael Eigen: Sensitivity (Site not responding. Last check: 2007-11-06)
		For Freud, such sensitivity is mediated by what he calls a pleasure or body ego, an idea which resonates with older writings on "the flesh," "concupiscence," mischievous, destructive, enlivening Eros.
		To further complicate matters and bring out a challenge sensitivity opens, the idea, whole, intuitive sense or gestalt formed in the movement from PS to D may itself be explosive, threatening, de-stabilizing.
		Sensitivity may be too much or too little for itself, moving between flooding and starvation, whether in sensory, emotional, social, aesthetic, ethical, intellectual or spiritual domains.

	What is Multiple Chemical Sensitivity? (MCS)
		Multiple Chemical Sensitivity; in broad terms it means an unusually severe sensitivity or allergy-like reaction to many different kinds of pollutants including solvents, VOC's (Volatile Organic Compounds), perfumes, petrol, diesel, smoke, "chemicals" in general and often encompasses problems with regard to pollen, house dust mites, and pet fur and dander.
		Multiple chemical sensitivity unlike true allergies - where the underlying mechanisms of the problem are relatively well understood widely accepted, is generally regarded as "idiopathic" - meaning that it has no known mechanism of causation and it's processes are not fully understood.
		Sensitization is a true allergic reaction to one chemical or irritant and is caused by involvement within the body of mast cells and IgE antibodies.

		Sensitivity may be loosely defined as the short sharp pain felt when something touches the affected tooth.
		Another important cause of sensitivity is trauma to the tooth - if any tooth is constantly being traumatized due to bite problems or improper occlusion then that tooth is likely to become sensitive.
		This is due to the irritation caused by the infection of the gums at the root surface of the tooth.

		By sensitivity we mean symptoms or signs as related to chemical exposures at levels tolerated by the population at large, that is distinct from such well recognized hypersensitivity phenomenon as IgG-mediated immediate hypersensitivity reactions, contact dermatitis, and hypersensitivity pneumonitis.
		Rea wrote that "at their onset, symptoms of chemical sensitivity are almost always reversible." This is a very positive statement; however, he added that when organ involvement increases, responses are more difficult to decipher and reverse.
		He wrote that the factors that are influencing the onset of chemical sensitivity are total body load, the nutritional state, and bioaccumulation of toxic substances, as well as other factors.

	Understanding Headphone Power Requirements (Site not responding. Last check: 2007-11-06)
		Headphone manufacturers specify a sensitivity rating for their products that is very similar to loudspeaker sensitivity ratings.
		Sensitivity is then stated as the number of dB of actual sound level (SPL) produced by the headphones with 1 mW of input; headphone specifications commonly refer to this by the misleading term dB/mW.
		Think about these sensitivity definitions a moment: headphone sensitivity is rated using 1/1000 of a watt; loudspeaker sensitivity is rated using 1 watt.

	Celiac Disease and Gluten Sensitivity
		Recently, with the discovery of antibodies which are specific for celiac disease, screening of families of celiacs and select populations have identified a growing number of asymptomatic individuals who have circulating antibodies and changes on intestinal biopsies characteristic of celiac disease.
		Removal of wheat (gluten) from the diet of individuals with celiac disease or gluten sensitivity results in regeneration of the intestinal mucosal absorptive surface area and resolution of symptoms in most patients.
		Though sensitive, this antibody is also found in other diseases and is therefore not specific for celiac disease.

	Multiple Chemical Sensitivity
		Many such people are seeking special accommodations, applying for disability benefits, and filing lawsuits claiming that exposure to common foods and chemicals has made them ill. Their efforts are supported by a small cadre of physicians who use questionable diagnostic and treatment methods.
		They believe that although some people are very sensitive to various microorganisms, noxious chemicals, and common foods, there is no scientific evidence that an immunologic basis exists for generalized allergy to environmental substances.

	Sensitivity
		Apart from a cavity or a missing filling, the most common cause of tooth sensitivity is exposed dentin on the roots of your teeth.
		Normally, the dentin (the second, more sensitive layer of the tooth) is surrounded and protected by your enamel, cementum(special root covering) and gums.
		It is believed that the little tubes that connect the dentin to the nerve or pulp serve as sensory conductors.

		Measure of the sound pressure level generated at a distance of one meter from a speaker when the speaker is fed a 2.83 volt signal (1 watt at 8 ohms); efficiency of a speaker creating a certain sound pressure level from a given input with high figures representing a more efficient speaker.
		Speakers with a high sensitivity are able to play louder with a given input than speakers with a low sensitivity.
		Thus a speaker operating at a sensitivity of 88 dB with a 200-watt amplifier would put out the same sound level as a speaker with a sensitivity of 91 dB being driven by a 100-watt amplifier.

	Butterfly Effect
		The "Butterfly Effect" is the propensity of a system to be sensitive to initial conditions.Such systems over time become unpredictable,this idea gave rise to the notion of a butterfly flapping it's wings in one area of the world,causing a tornado or some such weather event to occur in another remote area of the world.
		Comparing this effect to the domino effect,is slightly misleading.There is dependence on the initial sensitivity,but whereas a simple linear row of dominoes would cause one event to initiate another similar one,the butterfly effect amplifies the condition upon each iteration.
		Animal populations may also be subject to the same phenomena.Work done by Robert May,suggests that predator-prey systems have complex dynamics making them prone to "boom" and "bust",due to the difference equations that model them.
