Tapering (economics)
Quantitative easing (QE) is a monetary policy action whereby a central bank purchases predetermined amounts of government bonds or other financial assets in order to stimulate economic activity. Quantitative easing is a novel form of monetary policy that came into wide application after the financial crisis of 2007-2008. It is intended to stabilize an economic contraction when inflation is very low or negative and when standard monetary policy instruments have become ineffective. Quantitative tightening (QT) does the opposite, where for monetary policy reasons, a central bank sells off some portion of its own held or previously purchased government bonds or other financial assets, to a mix of commercial banks and other financial institutions, usually after periods of their own, earlier, quantitative easing purchases. Similar to conventional open-market operations used to implement monetary policy, a central bank implements quantitative easing by buying financial assets from com ...

Tapering (mathematics)
In mathematics, physics, and theoretical computer graphics, tapering is a kind of shape deformation. Just as an affine transformation, such as scaling or shearing, is a first-order model of shape deformation, tapering is a higher order deformation just as twisting and bending. Tapering can be thought of as non-constant scaling by a given tapering function. The resultant deformations can be linear or nonlinear. To create a nonlinear taper, instead of scaling in ''x'' and ''y'' for all ''z'' with constants as in: : q= \begin a & 0 & 0 \\ 0 & b & 0 \\ 0 & 0 & 1 \end p, let ''a'' and ''b'' be functions of ''z'' so that: : q= \begin a(p_z) & 0 & 0 \\ 0 & b(p_z) & 0 \\ 0 & 0 & 1 \end p. An example of a linear taper is a(z) = \alpha_0 + \alpha_1z, and a quadratic taper a(z) = _0 + _1z + _2z^2. As another example, if the parametric equation of a cube were given by ''ƒ''(''t'') = (''x''(''t''), ''y''(''t''), ''z''(''t'')), a nonlinear taper could be applied so that ...

Tapering (medicine)
In medicine, tapering is the practice of gradually reducing the dosage of a medication to reduce or discontinue it. Generally, tapering is done is to avoid or minimize withdrawal symptoms that arise from neurobiological adaptation to the drug. Prescribed psychotropic drugs that may require tapering due to this physical dependence include opioids, selective serotonin reuptake inhibitors, antipsychotics, anticonvulsants, and benzodiazepines. Cross-tapering Cross-tapering refers to the practice of reducing one drug, while introducing a new medication that is titrated to an effective dose. This can be used, for example, when changing antipsychotic medications. Peer support groups Peer support groups, such as ''survivingantidepressants.org'', provide a medium where those tapering medication can discuss approaches and withdrawal symptoms. ''Surviving antidepressants'' advocate for a slower rate of tapering than that used in standard medical practice. Many such groups exist on Fac ...

Opioid Tapering
Opioid tapering is the reduction of opioid Opioids are substances that act on opioid receptors to produce morphine-like effects. Medically they are primarily used for pain relief, including anesthesia. Other medical uses include suppression of diarrhea, replacement therapy for opioid us ... doses over time. Opioid tapering is typically done in people taking opioids for chronic pain. Tapering may be conducted in medically-supervised inpatient or outpatient settings. Community-based opioid tapering increased after the 2016 "Centers for Disease Control and Prevention, Center for Disease Control Guideline for Prescribing Opioids in Chronic Pain" was published, and many prescribers and organizations instigated opioid tapering practices in order to reduce opioid prescribing. While the CDC guideline was intended to inform primary care physicians on new prescription initiation, in many cases it was misapplied beyond this narrow scope and used to inform opioid tapering practices among ...

Tapering (signal Processing)
In signal processing and statistics, a window function (also known as an apodization function or tapering function) is a mathematical function that is zero-valued outside of some chosen interval, normally symmetric around the middle of the interval, usually near a maximum in the middle, and usually tapering away from the middle. Mathematically, when another function or waveform/data-sequence is "multiplied" by a window function, the product is also zero-valued outside the interval: all that is left is the part where they overlap, the "view through the window". Equivalently, and in actual practice, the segment of data within the window is first isolated, and then only that data is multiplied by the window function values. Thus, tapering, not segmentation, is the main purpose of window functions. The reasons for examining segments of a longer function include detection of transient events and time-averaging of frequency spectra. The duration of the segments is determined in e ...
