Superadditive effects of multiple lesions in a connectionist architecture: Implications for the neuropsychology of optic aphasia
We have tested this hypothesis by modeling superadditive effects of damage in a connectionist architecture.
More broadly, superadditive effects of damage provide a novel class of explanations for neuropsychological deficits that might previously have seemed to imply the existence of highly specialized processing components.

 Photographic silver halide developer composition and process for forming photographic silver images - Patent 5998110
The fl-and-white aqueous alkaline photographic developer composition of claim 1 wherein said auxiliary superadditive 3-pyrazolidone developing agent is represented by the formula: ##STR6## wherein R.sub.4 represents a phenyl group; and R.sub.5 and R.sub.6, which may be the same or different, each represents a hydrogen atom or an alkyl group.
Generally, the combinations of developing agents showing superadditivity consist of one developing agent from the dihydroxybenzene type (hydroquinone) and one developing agent from either the aminophenol type or the 3-pyrazolidone type.
The amount of such superadditive auxiliary developing agent used in the present invention is from about 0.001 to 0.2 moles per liter, preferably from about 0.025 to 0.1.

 Lower Expectations and Lower Previsions
Note this other fundamental fact: if you have a set of probability distributions that creates an affinely superadditive lower expectation, the convex hull of this set of distributions will create the same lower expectation.
The relationship between credal sets and superadditive, positively affine lower expectations is simple: they are different representations of the same thing.
For lower expectation models that are not superadditive positively affine, the situation is more complicated.

In contrast, the energetic effects of the 434 and 435, and 434 and 437, substitution pairs on binding of Ang are fully additive and 2.5 kcal/mol beyond additive, respectively.
Superadditivities (0.9-2.4 kcal/mol) are also observed for several multisite replacements involving these inhibitor residues and two Ang residues, Arg5 and Lys40, from this part of the interface.

Experiment Four:  The same procedure as Experiment 3 was replicated, but the bottom three associates of each list were used.
General Discussion:  So, when a full list was studied, they found a superadditive priming effect on the critical lures.
  When fewer items were presented, the superadditive priming was lost, but critical lures were still found to be more highly activated that than the non-presented control items.

On the other hand, superadditive lifting is descriptive in the sense that it requires the characterization of superadditive lifting functions.
It is well-known that mixed-integer rounding is a special case of superadditive lifting and in several cases mixed-integer rounding leads to strong valid inequalities.
These simple prescriptive techniques lead to strong superadditive lifting inequalities that are difficult to describe explicitly.

 AMCA: Power indices and the veil of ignorance by Federico Valenciano   (Site not responding. Last check: 2007-11-05)
That is, reinterpreting power indices as utility functions representing von Neumann-Morgenstern preferences over the set of lotteries on roles in simple superadditive games or the voting rules modeled by them.
As a result an axiomatization in Roth's setting emerges in which our axioms acquire a clear interpretation in terms of attitudes towards risk involving roles in voting rules under the "veil of ignorance" concerning the role to play.
It postulates the indifference between adopting the voting procedure described by any simple game and the one resulting from this when a minimal winning coalition is deleted, IF it is equally probable to play a role in the deleted coalition or in its complementary, and all roles are equally probable within each of these coalitions.

We put the word ``must" in quotation marks because the proof of this restriction is yet to exist.

In view of Theorem 4, the superadditivity conjecture is equivalent to the following property:

Large deviations for global maxima of independent superadditive processes with negative drift and an application to optimal sequence alignments
We examine the distribution of the global maximum of an independent superadditive process with negative drift.
We show that, under certain conditions, the distribution's upper tail decays exponentially at a rate that can be characterized as the unique positive zero of some limiting ogarithmic moment generating functio.

 General Notes: Photographic Formulas
It is still perfectly functional as a developer, though it tends to produce less contrast as it ages, and prints should always be developed face up to prevent unwanted stains.
The hydroquinone in the formula breaks down and ceases to produce its superadditive effect with the metol, but the metol and glycin continue to function long after the hydroquinone is exhausted.
Ansel Adams probably got the idea for his variant from using Ansco 130 well beyond the effective life of the hydroquinone.

 [No title]
All attempts to find superadditivity in BOLD signals using non-speech objects have been unsuccessful, and it has been suggested that the superadditive criterion may be too conservative for non-speech object stimuli (Beauchamp 2005: Laurienti et al.
One possible explanation for the lack of superadditive findings in BOLD is that fMRI must record from a population of neurons and lacks the capability to record from single neurons.
In that case, the experimenters would not have seen superadditivity in the BOLD signal even if multisensory neurons in the area were superadditive, but this would have been due to only the constraints of the BOLD signal itself.

Some of the significant results obtained in these works, however, relied on the assumption that the characteristic function games were superadditive.
This power index has a number of useful properties, including the satisfaction of individual rationality even when games are not superadditive.
Furthermore, there exists a strong relationship between the new power index and the core of the game (the set of stable solutions).

We explore the determinants of the payoffs an individual player may obtain in the equilibria of superadditive n-player coalitional games with transferable payoff.
We provide conditions necessary and sufficient for the lower bound on a player's equilibrium payoff to coincide with his reservation payoff, and show that if this lower bound is strictly larger than the reservation payoff, then there is an implied condition whose obvious interpretation is in terms of competing groups of players.

 Optimization Online - Integer programming, duality and superadditive functions
Abstract: Given $A \in Z^{m\times n}$, $b \in Z^m, c \in R^n$, we consider the integer program $P_d: \max \{c'x\vert Ax=b;x\in Z^n_+\}$ which has a well-known abstract dual optimization problem stated in terms of superadditive functions.
Using a linear program $Q$ equivalent to $P_d$ that we have introduced recently, we show that its dual $Q^*$ can be interpreted as a simplified and tractable form of the abstract superadditive dual, and identifies a subclass of superadditive functions, sufficient to consider in the abstract dual.
This class of superadditive functions is also used to characterize the integer hull of the convex polytope $\{x \in R^n\vert \:Ax=b;x\geq0\}$.
