Perceptual and Motor Skills, 1991
Since apparent brightness increases as an intermittent luminous source decreases from flicker fusion to approximately 10 cps, the phenomenal blackness induced by an intermittent annulus should also increase as a result of brightness contrast. However, data from 5 observers showed the phenomenal blackness occurring with a 10-cps inducer was greater ...

SSRN Electronic Journal, 2003 Abstract We analyze the issues relative to the formation of sub-unions in a federation, called enhanced cooperation agreements in the European Union. When centralization is not politically feasible, an agreement among a subset of countries may allow such countries to exploit benefits from coordination that would otherwise be lost.

Immunogenetics, 1996
Hypermutation at the immunoglobulin (Ig) loci increases the mutation rate more than 10(5)-fold over the normal, spontaneous rate. We studied two kinds of cis-acting elements - 3' enhancers and promoters - in a system in which a gene encoding the mu heavy (H) chain (Igm) is transfected in vitro into a cell line with an active Ig mutator.

IEEE Transactions on Computers, 1991
A hypercube with extra connections added between pairs of nodes through otherwise unused links is investigated. The extra connections are made in a way that maximizes the improvement of the performance measure of interest under various traffic distributions. The resulting hypercube, called the enhanced hypercube, requires a simple routing algorithm and

Enhancer Transcription And Enhancer Function
The FASEB Journal, 2016We utilize a combination of genome‐wide and genetic approaches to investigate molecular mechanisms that underlie the development and function of macrophages. Our studies suggest a relatively simple model of hierarchical interactions between lineage‐determining and signal‐dependent transcription factors that are required to select functional cis‐active ...

As the field of refractive surgery continues to evolve, an increasing number of surgical options are available for LASIK enhancements. Nonetheless, older methods such as AK continue to play an important role in enhancement procedures. Improvements in instruments and techniques allow for previously made LASIK flaps to be safely lifted for additional ...

Modern technological warfare requires a level of cognitive ability and discipline unique in the history of armed conflict. Recent advances in physiology, nutrition, neuroscience, and engineering offer a significant potential to prevent or reduce the degradation of a warfighter’s mental or physical capabilities in this demanding environment. The authors

Science, 1972
Presentation of a masking stimulus enhances, rather than detracts from, detectability of certain multisegment targets. Present theories of backward masking cannot account for this "backward enhancement" effect, which resembles another puzzling phenomenon, previously reported as target recovery or disinhibition.
