Episodes require treatment when they occur, and interval therapy may be used to prevent recurrence.

A return period also known as a recurrence interval is an estimate of the interval of time between events like an earthquake, flood or a river discharge flow of a certain intensity or size.

It is a statistical measurement denoting the average recurrence interval over an extended period of time, and is usually used for risk analysis ( e. g. to decide whether a project should be allowed to go forward in a zone of a certain risk, or to design structures to withstand an event with a certain return period.

A 100-year recurrence interval is the flood magnitude expected to be exceeded on the average of once in 100 years.

The inferred recurrence interval of Cascadia great earthquakes is approximately 500 years along the northern margin, and approximately 240 years along the southern margin.

for a spiral has motion as well as recurrence.

Psychotherapy is aimed at alleviating core symptoms, recognizing episode triggers, reducing negative expressed emotion in relationships, recognizing prodromal symptoms before full-blown recurrence, and, practicing the factors that lead to maintenance of remission Cognitive behavioural therapy, family-focused therapy, and psychoeducation have the most evidence for efficacy in regard to relapse prevention, while interpersonal and social rhythm therapy and cognitive-behavioural therapy appear the most effective in regard to residual depressive symptoms.

These recurrence relations are useful for discrete diffusion problems.

The APA guidelines state that, in general, pharmacotherapy of panic disorder should be continued for at least a year, and that clinical experience support continuing benzodiazepine treatment to prevent recurrence.

Successful treatment hinges on early diagnosis provided by a high index of suspicion and the use of CT scanning, nonoperative treatment for uncomplicated cases, and sometimes elective right hemicolectomy to prevent recurrence.

These results, however, are very sensitive to the accuracy of the twiddle factors used in the FFT ( i. e. the trigonometric function values ), and it is not unusual for incautious FFT implementations to have much worse accuracy, e. g. if they use inaccurate trigonometric recurrence formulas.

One way to find that analytic continuation is to use Euler's integral for positive arguments and extend the domain to negative numbers by repeated application of the recurrence formula,

Hyperinflation has always been a traumatic experience for the area which suffers it, and the next policy regime almost always enacts policies to prevent its recurrence.

In September 1967 Holt had suffered a recurrence of an old shoulder injury, which reportedly caused him agonising pain, and for this he was prescribed strong painkillers.

Many other types of solid tumors will be found to be very highly labeled on a case-by-case basis — a fact that becomes especially useful in searching for tumor metastasis, or for recurrence after a known highly active primary tumor is removed.

It may also be used as part of curative therapy, to prevent tumor recurrence after surgery to remove a primary malignant tumor ( for example, early stages of breast cancer ).

Transplanted kidneys are known to be affected by scleroderma and patients with early onset renal disease ( within one year of the scleroderma diagnosis ) are thought to have the highest risk for recurrence.

For traditional surgery, reported recurrence rates, which have been tracked for 10 years, range from 5-60 %.

Complications for ERA include burns, paraesthesia, clinical phlebitis, and slightly higher rates of deep vein thrombosis ( 0. 57 %) and pulmonary embolism ( 0. 17 %). One 3-year study compared ERA, with a recurrence rate of 33 %, to open surgery, which had a recurrence rate of 23 %.

" had composed a brilliant new score ( his most subtle yet ) to a scintillating libretto .... Iolanthe is the work in which Sullivan's operetta style takes a definite step forward, and metamorphosis of musical themes is its characteristic new feature .... By recurrence and metamorphosis of themes Sullivan made the score more fluid ...." Much of Sullivan's " fairy " music pays deliberate homage to the incidental music written by Felix Mendelssohn for a production of Shakespeare's A Midsummer Night's Dream.

* Recurrence period density entropy, an information-theoretic method for summarising the recurrence properties of a dynamical systems

A discrete function could be defined explicitly by a list, or by a formula for f ( n ) or it could be given implicitly by a recurrence relation or difference equation.

Although the recurrence risk is not increased, genetic counseling is often recommended for families who have had a pregnancy or child with Turner syndrome.

The MAC also condemned this act by Israel and called upon the Israeli authorities to take the strongest measures to prevent a recurrence of such a breach of the GAA and to refrain in the future from bringing to Jerusalem any equipment that was in excess of that allowed for under the terms of the GAA.

While surgery still remains as the standard for cystic echinococcosis treatment, there have been a number of studies that suggest that PAIR with chemotherapy is more effective than surgery in terms of disease recurrence, and morbidity and mortality.

In addition to the lack of efficacy, the required time commitment and the tendency for recurrence are additional reasons why individuals with SAD explore alternative treatments to light therapy.

Later events have since been assessed for probability of recurrence:

For such an online algorithm, a recurrence relation is required between quantities from which the required statistics can be calculated in a numerically stable fashion.

Adjuvant chemotherapy ( postoperative treatment ) can be used when there is little evidence of cancer present, but there is risk of recurrence.

For systems where the volume is preserved by the flow, Poincaré discovered the recurrence theorem: Assume the phase space has a finite Liouville volume and let F be a phase space volume-preserving map and A a subset of the phase space.

The recurrence of rheumatic fever is relatively common in the absence of maintenance of low dose antibiotics, especially during the first three to five years after the first episode.

This is shown by the recurrence of such words and phrases as:

In mathematical terms, the sequence F < sub > n </ sub > of Fibonacci numbers is defined by the recurrence relation

It is essential to face and prevent the recurrence of crises such as that

The gamma function must alternate sign between the poles because the product in the forward recurrence contains an odd number of negative factors if the number of poles between and is odd, and an even number if the number of poles is even.

" it is seen that when Wimsey is caught by a severe recurrence of his WWI shell-shock and nightmares, being taken care of by Bunter, the two of them revert to being " Major Wimsey " and " Sergeant Bunter ".

The logistic map is a polynomial mapping ( equivalently, recurrence relation ) of degree 2, often cited as an archetypal example of how complex, chaotic behaviour can arise from very simple non-linear dynamical equations.

This is partly based on risk of recurrence, but the internal / external divide is problematic.

The simultaneous treatment of all close contacts is recommended, even if they show no symptoms of infection ( asymptomatic ), to reduce rates of recurrence.

The generator is defined by the recurrence relation:

The Mersenne twister is a pseudorandom number generator developed in 1997 by and that is based on a matrix linear recurrence over a finite binary field.

This recurrence often occurs in times of relative immunosuppression, which is often in the context of malnutrition and other illnesses.
