The common frog is a poikilotherm and is able to function over a wide range of body core temperatures.. A poikilotherm (/ ˈ p ɔɪ k ə l ə ˌ θ ɜːr m, p ɔɪ ˈ k ɪ l ə ˌ θ ɜːr m /) is an animal (Greek poikilos – 'various', 'spotted', and therme – 'heat') whose internal temperature varies considerably.
Affected individuals initially notice a paleness of the affected region and feel severe pain. As the condition worsens, the region appears bluish and numb. In extreme cases, this will give way to paralysis and poikilothermia, possibly requiring amputation of the affected limb. [17]
The signs and symptoms of ischemia vary, as they can occur anywhere in the body and depend on the degree to which blood flow is interrupted. [4] For example, clinical manifestations of acute limb ischemia (which can be summarized as the "six P's") include pain, pallor, pulseless, paresthesia, paralysis, and poikilothermia.
In the LWE problem, the input to the algorithm has errors, i.e. for each pair () with some small probability. The errors are believed to make the problem intractable (for appropriate parameters); in particular, there are known worst-case to average-case reductions from variants of SVP. [12]
In 2014, Artur Avila won a Fields Medal for work including the solution of three Simon problems. [5] [6] Among these was the problem of proving that the set of energy levels of one particular abstract quantum system was, in fact, the Cantor set, a challenge known as the "Ten Martini Problem" after the reward that Mark Kac offered for solving it ...
With proper surgical care, acute limb ischaemia is a highly treatable condition; however, delayed treatment (beyond 6 to 12 hours) can result in permanent disability, amputation, and/or death. Early detection and steps towards fixing the problem with limb-sparing techniques can salvage the limb.
Likewise, renal insufficiency is sometimes caused by heart problems, and the treatment is thus led by a cardiologist. In psychiatry, however, grouping mental disorders by their cause is still an unsolved problem. Psychiatric textbooks and manuals cluster disorders by symptoms, which is thought to impede the search for effective treatments.
In mathematics, a collocation method is a method for the numerical solution of ordinary differential equations, partial differential equations and integral equations.The idea is to choose a finite-dimensional space of candidate solutions (usually polynomials up to a certain degree) and a number of points in the domain (called collocation points), and to select that solution which satisfies the ...
