* Positive feedback

Positive feedback loops, such as the simple X activates Y and Y activates X motif, essentially links output signals to their input signals and have been noted to be an important regulatory motif in cellular signal transduction because positive feedback loops can create switches with an all-or-nothing decision.

Some circuits may use Positive feedback and Negative feedback around the same amplifier, for example Triangle wave oscillators and active filters.

* Positive feedback

* Positive feedback

Positive feedback then occurs from the cross-connected inverters, thereby amplifying the small voltage difference between the odd and even row bit-lines of a particular column until one bit line is fully at the lowest voltage and the other is at the maximum high voltage.

Positive feedback ( or regenerative feedback ) occurs in a feedback loop when the mathematical sign of the net gain around the feedback loop ( sometimes called the loop gain ) is positive .< ref name = theorymodelling >

Positive feedback is a process in which the effects of a small disturbance on a system can include an increase in the magnitude of the perturbation.

Positive feedback tends to cause system instability.

Positive feedback may be controlled by signals in the system being filtered, damped, or limited, or it can be cancelled or reduced by adding negative feedback.

Positive feedback is used in digital electronics to force voltages away from intermediate voltages into ' 0 ' and ' 1 ' states.

Positive feedback in chemical reactions can increase the rate of reactions, and in some cases can lead to explosions.

Positive feedback in mechanical design causes tipping-point, or ' over-centre ', mechanisms to snap into position, for example in switches and locking pliers.

Positive feedback in economic systems can cause boom-then-bust cycles.

::" Positive feedback loops are sources of growth, explosion, erosion, and collapse in systems.

* The Inner Planes ( representing planes of elemental nature, such as Water, Earth, Fire, and Air, as well as the Positive and Negative energy planes )

Also called the Positive Material Plane ( in 1st Edition ), this is the plane of creation and energy, and is the total opposite of the Negative Energy plane.

Positive reactions include reported feelings of well being and a welcome energy boost.

Currently under construction, the NASA Ames Research Center's Sustainability Base, is designed to be a Net Positive building — producing more energy than it needs — with potable water consumption by more than 90 % when compared to an equivalent size building of conventional design, significantly reduced building maintenance costs when compared to an equivalent size building of conventional design, and an expected Platinum LEED certification.

Positive buoyant energy was estimated at 1200 j / kg over the Raleigh area

Positive mood can be caused by many different aspects of life as well as have certain effects on people as a whole.

‘ Positive ’ symptoms were caused by the functional release of the lower centres.

However, subsequent episodes such as season three's " Proof Positive " show that McGee's real intentions lie much deeper than this, and that his main motive is purely to understand this fascinating creature ( to whom his references as the Hulk are not shared by other characters ) for himself, for his amazement at the existence of such a remarkable creature has caused him to become totally obsessed with the Hulk to the extent that it has ruined his personal life ; the Hulk is permanently on his mind, and his annoyance over his lack of success in catching the Hulk is exacerbated by other people's refusal even to believe that the Hulk actually exists — not even his own colleagues at the National Register take the story seriously, and they view him as a laughing stock for believing that the Hulk is real.

Ratified in the Republican Party victory in 1952, the Positive State is now evidenced by political campaigns being waged not on whether but on how much social legislation there should be.

* Lex Naturalis, Ius Naturalis: Law as Positive Reasoning and Natural Rationality by Eric Engle, ( Elias Clarke, 2010 ).

For the and cases, a necessary and sufficient criterion for separability is given by the famous Positive Partial Transpose ( PPT ) condition.

This album, which drew inspiration from both soul and Motown, was produced by Mike Hedges, who had replaced Roger Bechirian as the Undertones ' producer following the 1981 release of Positive Touch.

*" Debunking as Positive Science " by Richard York and Brett Clark

Positive WNV test kits obtained via use of these kits should be confirmed by additional testing at a state health department laboratory or CDC.

Positive accounts of Aboriginal customs and encounters are also recorded in the journals of early European explorers, who often relied on Aboriginal guides and assistance: Charles Sturt employed Aboriginal envoys to explore the Murray-Darling ; the lone survivor of the Burke and Wills expedition was nursed by local Aborigines, and the famous Aboriginal explorer Jackey Jackey loyally accompanied his ill-fated friend Edmund Kennedy to Cape York.

Positive rights such as a " right to medical care " are emphasized more often by left-leaning thinkers, while right-leaning thinkers place more emphasis on negative rights such as the " right to a fair trial ".

Positive growth returned in 1999, however, aided by a 20 % devaluation of the Fijian dollar.

Positive electrode development was done by Dr. Masahiko Oshitani from GS Yuasa Company, who was the first to develop high-energy paste electrode technology.

The organ was totally reconstructed in 1997 by Klais Orgelbau of Bonn, retaining the existing instrument as far as was possible and restoring it largely to its 1895 condition, although the Positive division was kept.

* Positive hosting — attracts or is inhabited by beneficial insects or other organisms which benefit plants, as with ladybugs or some " good nematodes ".

; Positive association of social and individual values: ( or monotonicity ) If any individual modifies his or her preference order by promoting a certain option, then the societal preference order should respond only by promoting that same option or not changing, never by placing it lower than before.

The film inspired the song " One For the Cutters " by The Hold Steady, which appeared on their 2008 album Stay Positive.

* Detection Rate: The detection rate is defined as the number of intrusion instances detected by the system ( True Positive ) divided by the total number of intrusion instances present in the test set.

* False Alarm Rate: defined as the number of ' normal ' patterns classify as attacks ( False Positive ) divided by the total number of ' normal ' patterns.

# Positive reinforcement ( Reinforcement ): occurs when a behavior ( response ) is followed by a stimulus that is appetitive or rewarding, increasing the frequency of that behavior.

# Positive punishment ( Punishment ) ( also called " Punishment by contingent stimulation "): occurs when a behavior ( response ) is followed by a stimulus, such as introducing a shock or loud noise, resulting in a decrease in that behavior.
