An Integrated Encyclopedia of DNA Elements in the Human Genome

open access: yesNature, 2012
The human genome encodes the blueprint of life, but the function of the vast majority of its nearly three billion bases is unknown. The Encyclopedia of DNA Elements (ENCODE) project has systematically mapped regions of transcription, transcription factor

Lubricant film formation in rough surface non-conformal conjunctions subjected to GPa pressures and high slide-to-roll ratios

open access: yesScientific Reports, 2020
A ball-on-disc machine was employed in a highly idealised setting to study the interplay between oil film formation and surface irregularities in single-sided rough elasto-hydrodynamic lubricated (EHL) conjunctions.

In-situ polymerized siloxane urea enhanced graphene-based super-fast, durable, all-weather elec-photo-thermal anti-/de-icing coating

open access: yesJournal of Science: Advanced Materials and Devices, 2023
Ice accumulation is a pervasive natural phenomenon that exerts a severe and catastrophic impact on a broad range of social systems. Previous investigations on anti-/de-icing techniques have primarily focused on mild laboratory conditions, which have ...

Simple combinations of lineage-determining transcription factors prime cis-regulatory elements required for macrophage and B cell identities

open access: yesMolecules and Cells, 2010
Summary Genome-scale studies have revealed extensive, cell type-specific co-localization of transcription factors, but the mechanisms underlying this phenomenon remain poorly understood.

Expanded encyclopaedias of DNA elements in the human and mouse genomes

open access: yesNature, 2020
The human and mouse genomes contain instructions that specify RNAs and proteins and govern the timing, magnitude, and cellular context of their production. To better delineate these elements, phase III of the Encyclopedia of DNA Elements (ENCODE) Project
