Enhancer selectivity in space and time: from enhancer–promoter interactions to promoter activation

Nature Reviews Molecular Cell Biology
The primary regulators of metazoan gene expression are enhancers, originally functionally defined as DNA sequences that can activate transcription at promoters in an orientation-independent and distance-independent manner.

Kindling the Darkness: A Practical Low-light Image Enhancer

ACM Multimedia, 2019
Images captured under low-light conditions often suffer from (partially) poor visibility. Besides unsatisfactory lightings, multiple types of degradations, such as noise and color distortion due to the limited quality of cameras, hide in the dark.

Deep Photo Enhancer: Unpaired Learning for Image Enhancement from Photographs with GANs

2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2018
This paper proposes an unpaired learning method for image enhancement. Given a set of photographs with the desired characteristics, the proposed method learns a photo enhancer which transforms an input image into an enhanced image with those ...

ENHANCING EVOLUTION AND ENHANCING EVOLUTION

Bioethics, 2010
ABSTRACTIt has been claimed in several places that the new genetic technologies allow humanity to achieve in a generation or two what might take natural selection hundreds of millennia in respect of the elimination of certain diseases and an increase in traits such as intelligence.

Are “Genetic Enhancements” Really Enhancements?

Cambridge Quarterly of Healthcare Ethics, 2000
The word enhancement is value laden and potentially misleading in the context of genetics. Dictionary definitions of enhance include “increase in value,” “improve,” “appreciate,” and “inflate.” The term genetic enhancement would be better replaced with a more neutral term such as “genetic manipulation” to reflect the fact that the consequences ...

Evaluating Enhancer Function and Transcription.

Annual Review of Biochemistry, 2020
Cell-type- and condition-specific profiles of gene expression require coordination between protein-coding gene promoters and cis-regulatory sequences called enhancers.

Adaptive contrast enhancement and de-enhancement

Pattern Recognition, 1991
Abstract Two different interpolative schemes for adaptive contrast enhancement have been presented for speeding up the contrast enhancement algorithm proposed by Beghdadi and Negrate. To reduce the enhancement of noise in relatively flat regions present in the image, an adaptive power variation technique is used in which the degree of contrast ...
