A 1-dimensional statistical mechanics model for nucleosome positioning on genomic DNA
The first level of folding of DNA in eukaryotes is provided by the so-called “10-nm chromatin fibre”, where DNA wraps around histone proteins (∼10 nm in size) to form nucleosomes, which go on to create a zig-zagging ... -
All-purpose, all-sky photometric redshifts for the DESI Legacy Imaging Surveys DR8
This dataset contains the catalogues described in Duncan et al. (2022), which presents photometric redshift (photo-z) estimates for the Dark Energy Spectroscopic Instrument (DESI) Legacy Imaging Surveys, currently the most ... -
Ammonium fluoride's analogy to ice: possibilities and limitations
Ammonium fluoride, NH4F, is often seen as an analogue to ice, with several of its solid phases closely resembling known ice phases. While its ionic and hydrogen-ordered nature puts topological constraints on the ice-like ... -
Bacteria as living patchy colloids: Phenotypic heterogeneity in surface adhesion
This dataset contains data corresponding to the figures in the main text of the manuscript "Bacteria as living patchy colloids: Phenotypic heterogeneity in surface adhesion" (Science Advances, 4, 4, eaao1170, 2018). Data ... -
Bicontinuous Soft Solids with a Gradient in Channel Size Designed for Energy Storage Applications
Examples of bicontinuous interfacially jammed emulsion gels ("bijels") are presented with a designed gradient in the channel size along the sample. These samples are created by quenching binary fluids which have a gradient ... -
BioRock rare earth element leaching data
Sets of data from the ESA BioRock experiment showing biomining/bioleaching of elements (rare earth elements). Experiment on board of the International Space Station to study microbe-mineral interactions in space. Data in ... -
BslA-stabilised emulsion droplets with designed microstructure
Original microscope images of BslA-stabilised emulsion droplets and two time-lapse confocal microscope sequences (available to view using ImageJ imaging software) of BslA-stabilised partially coalesced droplets melting in ... -
Changes of Fermi Surface Topology due to the Rhombohedral Distortion in SnTe
Stoichiometric SnTe is theoretically a small gap semiconductor that undergoes a ferroelectric distortion on cooling. In reality however, crystals are always nonstoichiometric and metallic; the ferroelectric transition is ... -
Changing the flow profile and resulting drying pattern of dispersion droplets via contact angle modification
Dataset corresponding to arXiv pre-print of: "Changing the flow profile and resulting drying pattern of dispersion droplets via contact angle modification". -
Chaotic behaviour of Eulerian MHD turbulence
We study the chaos of a turbulent conducting fluid using direct numerical simulation in the Eulerian frame. We predict that the Lyapunov exponent, which measures the exponential separation of initially close solutions of ... -
Chaotic properties of a turbulent isotropic fluid
By tracking the divergence of two initially close trajectories in phase space of forced turbulence, the relation between the maximal Lyapunov exponent λ, and the Reynolds number Re is measured using direct numerical ... -
Characterising shear-induced dynamics in flowing complex fluids using differential dynamic microscopy
Microscopic dynamics reveal the origin of the bulk rheological response in complex fluids. In model systems particle motion can be tracked, but for industrially relevant samples this is often impossible. Here we adapt ... -
Characteristics of small protoplanetary disc warps in kinematic observations
Dataset for the paper "Characteristics of small protoplanetary disc warps in kinematic observations" which was published in MNRAS . The dataset contains the hydrodynamical and radiative transfer output files from which the ... -
Chicxulub data
Data on the microbiology of the Chicxulub crater (Mexico) and associated geochemical data. -
Code and accessories for 'Subcritical instabilities in plane Poiseuille flow of an Oldroyd-B fluid'
Recently, detailed experiments on visco-elastic channel flow have provided convincing evidence for a nonlinear instability scenario which we had argued for based on calculations for visco-elastic Couette flow. Motivated ... -
Comparison of forcing functions in magnetohydrodynamics
Results are presented of direct numerical simulations of incompressible, homogeneous magnetohydrodynamic turbulence without a mean magnetic field, subject to different kinetic forcing functions commonly used in the literature. ... -
Competing Timescales Lead to Oscillations in Shear-Thickening Suspensions
Competing timescales generate novelty. Here, we show that a coupling between the timescales imposed by instrument inertia and the formation of interparticle frictional contacts in shear-thickening suspensions leads to ... -
Complex small-world regulatory networks emerge from the 3D organisation of the human genome
The discovery that overexpressing one or a few critical transcription factors can switch cell state suggests that gene regulatory networks are relatively simple. In contrast, genome-wide association studies (GWAS) point ... -
Computational phase diagrams of noble gas hydrates under pressure
We present results from a first-principles study on the stability of noble gas-water compounds in the pressure range 0-100 kbar. Filled-ice structures based on the host water networks ice-Ih, ice-Ic, ice-II, and C0 interacting ... -
Conching chocolate is a prototypical transition from frictionally jammed solid to flowable suspension with maximal solid content
The mixing of a powder of 10-50μm primary particles into a liquid to form a dispersion with the highest possible solid content is a common industrial operation. Building on recent advances in the rheology of such 'granular ...
