  Limit superior and limit inferior
In mathematics, the limit inferior and limit superior of a sequence can be thought of as limiting bounds on the sequence.
The value of this limit inferior is conjectured to be 2 - this is the Twin Prime Conjecture - but as yet has not even been proved finite.
The power set P(X) of a set X is a complete lattice, and it is sometimes useful to consider limits superior and inferior of sequences in P(X), that is, sequences of subsets of X.

 Limit superior and limit inferior - Wikipedia, the free encyclopedia
In mathematics, the limit inferior and limit superior (also called infimum limit and supremum limit, or liminf and limsup) of a sequence can be thought of as limiting bounds on the sequence.
Whenever the ordinary limit exists, the limit inferior and limit superior are both equal to it; therefore, each can be considered a generalization of the ordinary limit which is primarily interesting in cases where the limit does not exist.
Limits inferior/superior are related to big-O notation in that they bound a sequence only "in the limit"; the sequence may exceed the bound.

 Gray, Henry. 1918. Anatomy of the Human Body. Page 824
The superior temporal gyrus lies between the posterior ramus of the lateral fissure and the superior temporal sulcus, and is continuous behind with the supramarginal and angular gyri.
The inferior temporal gyrus is placed below the middle temporal sulcus, and is connected behind with the inferior occipital gyrus; it also extends around the infero-lateral border on to the inferior surface of the temporal lobe, where it is limited by the inferior sulcus.
Lateral to this fissure is the narrow tentorial part of the inferior temporal gyrus, and medial to it the fusiform gyrus, which extends from the occipital to the temporal pole; this gyrus is limited medially by the collateral fissure, which separates it from the lingual gyrus behind and from the hippocampal gyrus in front.

the groove between the duodenum and the right lateral and lower borders in front are the anastomosing superior and inferior pancreaticoduodenal arteries; the common bile duct descends behind, close to the right border, to its termination in the descending part of the duodenum.
The superior mesenteric artery passes down in front of the left half across the uncinate process; the superior mesenteric vein runs upward on the right side of the artery and, behind the neck, joins with the lienal vein to form the portal vein.
The inferior surface (facies inferior) is narrow on the right but broader on the left, and is covered by peritoneum; it lies upon the duodenojejunal flexure and on some coils of the jejunum; its left extremity rests on the left colic flexure.

 Special Study: Display of Customer Limit Orders
Because of the importance of limit order display to our markets, and indications that many limit orders are not being handled appropriately, the examination staff will focus efforts on ensuring that specialists and OTC market makers comply with limit order display obligations, and when appropriate, will refer serious violations to the Division of Enforcement.
Limit orders compete for trades because limit orders that are displayed have a greater chance of attracting other orders in the market.
The exchange represented that it reviewed limit order display compliance as part of each of the 322 investigations and found no instances in which the order(s) were not displayed in accordance with the exchange's rules and, therefore did not discipline any dealers for failing to display the best available customer limit orders.

 Limitations of Nanoweapons
These limits mean that countermeasures based on pre-nano technologies are often effective at slowing the advance of nanoweapons and sometimes capable of stopping nanotechnology altogether.
Nanotech devices are limited to using ultraviolet light or visible light in the blue to violet range as a medium of sensing or as a photovoltaic power source.
This well-known limitation means that purely military installations that require protection from nanoweapons are often built in places that are poor in those frequencies of light.

Inferior is not bound to initiate a cancellation action on the expiry of timeout; it takes a cancellation decision at its own discretion, which could even be before the expiry of timeout.
This time limit allows a Superior to tell Inferiors that they should be prepared to hold on to their promises after a prepared message is sent for a minimum period of time.
This indicates to the Inferior that the Superior is aware of the contradictory decision taken by it.

 Developing Intelligence: Multiple Capacity Limitations for Visual Working Memory
A fundamental debate concerns whether memory capacity limitations may be due to some central bottleneck, or whether there is an array of lower-level limitations that give rise to the simple "span" measures, or to the magic number "seven plus or minus two," frequently observed in behavioral experiments.
In the March issue of Nature, Xu & Chun describe their work to dissociate the contributions of inferior and superior intraparietal sulcus to visual short term memory, based on a visual short-term memory task in which both set size and object complexity was manipulated.
To further investigate whether VSTM capacity limits are due to item complexity, number of items, or both, Xu and Chun had subjects attempt to detect a change in the shape of 1 item from a display of 1, 2, 3, 4, or 6 "simple" or "complex" objects, while inside an fMRI magnet.

 eMedicine - Brown Syndrome : Article Excerpt by: Kenneth Wright, MD   (Site not responding. Last check: 2007-11-03)
Brown attributed the limited elevation to a short or tight anterior superior oblique tendon sheath.
Subsequent studies confirmed the cause of the syndrome to be a tight or inelastic superior oblique tendon.
In constant or intermittent acquired Brown syndrome, reduced telescoping elongation of the superior oblique tendon would be due to one of the following: vascular dilatation of the tendon sheath vessels and local edema occurring within the confined area of the trochlea.

The superior properties of Liquidmetal alloys are made possible by revolutionary scientific and technological innovations.
This is in distinct contrast to conventional metals where the as-cast forms have inferior mechanical properties compared to their wrought and forged forms, which limits the fabrication of intricate and sophisticated designs.
This very unique combination of superior properties in the domain of high-strength metals and the fabrication characteristics of plastics positions the family of Liquidmetal alloys as the new paradigm in materials science.

 Limit of a function - Wikipedia, the free encyclopedia
In mathematics, the limit of a function is a fundamental concept in mathematical analysis.
The limit of a function f(x) as x approaches c is a number L with the following property: given any target neighborhood of L, there is a neighborhood of c over which the values of f(x) remain within the target neighborhood.
This explicit statement is quite close to the formal definition of the limit of a function with values in a Hausdorff topological space.

The validity of an "upper limits" standard may later be called into question should the public not have a voice in their formation.
There is concern that the establishment of "tolerable upper limits" would cause some consumers to needlessly seek the counsel of a physician or other health professional when high-dose vitamin usage is in question.
Specifically, if an upper limit of consumption is established for magnesium, and excessive dosage may produce known symptoms of "loose stool," then this fact should be provided to consumers with the notation that the remedy is to reduce the dosage and that this symptom is completely reversible.
