BACKGROUND: Levels of self-reported health do not always correlate with levels of physical disability in stroke survivors. We aimed to explore what underlies the difference between subjective self-reported health and objectively...

Octahedral platinum(iv) complexes such as trans,trans,trans-[Pt(N3)2(OH)2(pyridine)2] (1) are stable in the dark, but potently cytotoxic to a range of cancer cells when activated by UVA or visible light, and active in vivo....

The role of radiology in anatomy teaching in UK medical schools
AIMS: To investigate the current use of radiology in anatomy teaching across the UK, and to determine the level of interest expressed in expanding its role in medical education. MATERIALS AND METHODS: A 22-question electronic...
Repeated daily restraint stress induces adaptive behavioural changes in both adult and juvenile mice
Chronic stress is known to be a risk factor for the development of depression and anxiety, disorders which often begin during adolescence. Restraint stress is a commonly used stressor in adult rodents, however the effects of...

Sharp bounds on Helmholtz impedance-to-impedance maps and application to overlapping domain decomposition
We prove sharp bounds on certain impedance-to-impedance maps (and their compositions) for the Helmholtz equation with large wavenumber (i.e., at high frequency) using semiclassical defect measures. Gong et al. (Numer. Math....
A new transform method I
A new method for solving boundary-value problems (BVPs) for linear and certain nonlinear PDEs was introduced by one of the authors in the late 1990s. For linear PDEs, this method constructs novel integral representations (IRs)...
Model free audit methodology for bias evaluation of tumour progression in oncology
Many oncology studies incorporate a blinded independent central review (BICR) to make an assessment of the integrity of the primary endpoint, progression free survival. Recently, it has been suggested that, in order to assess...

Chronic stress is known to be a risk factor for the development of depression and anxiety, disorders which often begin during adolescence. Restraint stress is a commonly used stressor in adult rodents, however the effects of...
Analysis of a Helmholtz preconditioning problem motivated by uncertainty quantification
This paper analyses the following question: let Aj, j = 1,2, be the Galerkin matrices corresponding to finite-element discretisations of the exterior Dirichlet problem for the heterogeneous Helmholtz equations ∇⋅ (Aj∇uj) +...
Re: the role of radiology in anatomy teaching in UK medical schools
Sir – We thank Raja and colleagues1 for their interest in our article and share their enthusiasm for the integration of radiology in anatomy teaching. This is something that we feel passionate about. Two of our authors are...
Scattering by finely-layered obstacles
We consider the scalar Helmholtz equation with variable, discontinuous coefficients, modeling transmission of acoustic waves through an anisotropic penetrable obstacle. We first prove a well-posedness result and a...
High-frequency bounds for the Helmholtz equation under parabolic trapping and applications in numerical analysis
This paper is concerned with resolvent estimates on the real axis for the Helmholtz equation posed in the exterior of a bounded obstacle with Dirichlet boundary conditions when the obstacle is trapping. There are two resolvent...
Wavenumber-explicit parametric holomorphy of Helmholtz solutions in the context of uncertainty quantification
A crucial role in the theory of uncertainty quantification (UQ) of PDEs is played by the regularity of the solution with respect to the stochastic parameters; indeed, a key property one seeks to establish is that the solution...

Spurious Quasi-Resonances in Boundary Integral Equations for the Helmholtz Transmission Problem
We consider the Helmholtz transmission problem with piecewise-constant material coefficients, and the standard associated direct boundary integral equations. For certain coefficients and geometries, the norms of the inverses of...
Arylboronic Acid Catalyzed C-Alkylation and Allylation Reactions Using Benzylic Alcohols
The arylboronic acid catalyzed dehydrative C-alkylation of 1,3-diketones and 1,3-ketoesters using secondary benzylic alcohols as the electrophile is reported, forming new C–C bonds (19 examples, up to 98% yield) with the release...
Numerical estimation of coercivity constants for boundary integral operators in acoustic scattering
Coercivity is an important concept for proving existence and uniqueness of solutions to variational problems in Hilbert spaces. But while coercivity estimates are well known for many variational problems arising from partial...
Domain decomposition preconditioning for high-frequency Helmholtz problems with absorption
In this paper we give new results on domain decomposition preconditioners for GMRES when computing piecewise-linear finite-element approximations} of the Helmholtz equation $-\Delta u - (k^2+ \ri \eps)u = f$, with absorption...
