Collective Modes of a Soliton Train in a Fermi Superfluid.
We characterize the collective modes of a soliton train in a quasi-one-dimensional Fermi superfluid, using a mean-field formalism. In addition to the expected Goldstone and Higgs modes, we find novel long-lived gapped modes...

Genetic disruption of serine biosynthesis is a key driver of macular telangiectasia type 2 aetiology and progression
Abstract: Background: Macular telangiectasia type 2 (MacTel) is a rare, heritable and largely untreatable retinal disorder, often comorbid with diabetes. Genetic risk loci subtend retinal vascular calibre and...

Massively parallel solvers for elliptic partial differential equations in numerical weather and climate prediction
The demand for substantial increases in the spatial resolution of global weather and climate prediction models makes it necessary to use numerically efficient and highly scalable algorithms to solve the equations of large-scale...

Development of a core competency framework for clinical informatics
Objectives: Until this point there was no national core competency framework for clinical informatics in the UK. We report on the final two iterations of work carried out in the formation of a national core competency framework....

The Role of Mediators in Diffusing the Community Foundation Model of Philanthropy
We examine the role of mediators in locally embedding the community foundation model of philanthropy to enable its global diffusion. We hold that mediators, as trusted agents within elite networks, promote and legitimate...

Efficient multigrid preconditioners for atmospheric flow simulations at high aspect ratio
Many problems in fluid modelling require the efficient solution of highly anisotropic elliptic partial differential equations (PDEs) in ‘flat’ domains. For example, in numerical weather and climate prediction, an elliptic PDE...

Robust set-point regulation for ecological models with multiple management goals

Population managers will often have to deal with problems of meeting multiple goals, for example, keeping at specific levels both the total population and population abundances in given stage-classes of a stratified...

Improving multilevel Monte Carlo for stochastic differential equations with application to the Langevin equation
This paper applies several well-known tricks from the numerical treatment of deterministic differential equations to improve the efficiency of the multilevel Monte Carlo (MLMC) method for stochastic diffe- rential equations...

Matrix-free GPU implementation of a preconditioned conjugate gradient solver for anisotropic elliptic PDEs

Many problems in geophysical and atmospheric modelling require the fast solution of elliptic partial differential equations (PDEs) in “flat” three dimensional geometries. In particular, an anisotropic elliptic PDE for the...

High Circular Polarization of Electroluminescence Achieved via Self-Assembly of a Light-Emitting Chiral Conjugated Polymer into Multidomain Cholesteric Films.
We demonstrate a facile route to obtain high and broad-band circular polarization of electroluminescence in single-layer polymer OLEDs. As a light-emitting material we use a donor-acceptor polyfluorene with enantiomerically pure...

Ophthalmology of clinically normal alpacas ( Vicugna pacos ) in the United Kingdom
Background: Alpacas are being more frequently presented to veterinarians in the UK. It is important to validate whether published normal ocular parameters are consistent with the alpaca population in the UK. Methods: Ophthalmic...

Petascale solvers for anisotropic PDEs in atmospheric modelling on GPU clusters
Memory bound applications such as solvers for large sparse systems of equations remain a challenge for GPUs. Fast solvers should be based on numerically efficient algorithms and implemented such that global memory access is...

Evidence vs. Professional Judgment in Ranking “Power Few” Crime Targets
Abstract: Research question: How accurately can local police officers use professional judgement to identify the highest-crime street locations and offenders with the most crime and harm, in comparison to an evidence-based...
