Revealing the Mechanism of Sodium Diffusion in NaxFePO4 Using an Improved Force Field
(Journal of Physical Chemistry C, 20180402)Olivine NaFePO4 is a promising cathode material for Naion batteries. Intermediate phases such as Na0.66FePO4 govern phase stability during intercalationdeintercalation processes, yet little is known about Na+ diffusion ... 
Suggestion of reduced cancer risks following cardiac xray exposures is unconvincing
(European Journal of Epidemiology, 20180331) 
On Adomian Based Numerical Schemes for Euler and NavierStokes Equations, and Application to Aeroacoustic Propagation
(20180312)In this thesis, an Adomian Based Scheme (ABS) for the compressible NavierStokes equations is constructed, resulting in a new multiderivative type scheme not found in the context of fluid dynamics. Moreover, this scheme ... 
Quantitative weighted estimates for singular integrals and commutators
(20180227)In this dissertation several quantitative weighted estimates for singular integral op erators, commutators and some vector valued extensions are obtained. In particular strong and weak type $(p, p)$ estimates, CoifmanFe ... 
Time resolved amplified FRET identifies protein kinase B activation state as a marker for poor prognosis in clear cell renal cell carcinoma
(BBA Clinical, 201712)Purpose Clear cell Renal Cell Carcinomas (ccRCC), the largest group of renal tumours, are resistant to classical therapies. The determination of the functional state of actionable biomarkers for the assessment of these ... 
Acute toxicity, bioaccumulation and effects of dietary 1 transfer of silver from brine 2 shrimps exposed to PVP/PEIcoated silver nanoparticles to zebrafish
(Comparative Biochemistry and Physiology  part C: Toxicology & Pharmacology, 20170318)The extensive use and release to the aquatic environment of silver nanoparticles (NPs) could lead to their incorporation into the food web. Brine shrimp larvae of 24 h showed low sensitivity to the exposure to PVP/PEIcoated ... 
Sample size impact on the categorisation of continuous variables in clinical prediction
(Trends in Mathematics. Research Perspectives CRM Barcelona. Extended Abstracts Fall 2015. Biomedical Big Data; Statistics for Low Dose Radiation Research, 201712)Recent advances in information technologies are generating a growth in the amount of available biomedical data. In this paper, we studied the impact sample size may have on the categorisation of a continuous predictor ... 
A new approach to categorize continuous variables in prediction models: Proposal and validation
(Statistical Methods in Medical Research, 201712)When developing prediction models for application in clinical practice, health practitioners usually categorise clinical variables that are continuous in nature. Although categorisation is not regarded as advisable from ... 
Variable Lorentz estimate for nonlinear elliptic equations with partially regular nonlinearities
(Nonlinear Analysis, 20180215)We prove global Calder\'onZygmund type estimate in Lorentz spaces for variable power of the gradients to weak solution of nonlinear elliptic equations in a nonsmooth domain. We mainly assume that the nonlinearities are ... 
Zero limit of entropic relaxation time for the Shliomis model of ferrofluids
(20180211)We construct solutions for the Shilomis model of ferrofluids in a critical space, uniformly in the entropic relaxation time $ \tau \in (0, \tau_0) $. This allows us to study the convergence when $ \tau\to 0 $ for such solutions. 
Lorentz estimates for the gradient of weak solutions to elliptic obstacle problems with partially BMO coefficients
(Boundary Value Problems, 2017)We prove global Lorentz estimates for variable power of the gradient of weak solution to linear elliptic obstacle problems with small partially BMO coefficients over a bounded nonsmooth domain. Here, we assume that the ... 
Weghted Lorentz and LorentzMorrey estimates to viscosity solutions of fully nonlinear elliptic equations
(Complex Variables and Elliptic Equations, 2018)We prove a global weighted Lorentz and LorentzMorrey estimates of the viscosity solutions to the Dirichlet problem for fully nonlinear elliptic equation $F(D^{2}u,x)=f(x)$ defined in a bounded $C^{1,1}$ domain. The ... 
Modelling of Thermal Sterilization of highmoisture snack foods: feasibility analysis and optimization
(Food and Bioprocess Technology, 201801)Highmoisture snacks, such as steamed buns and rice cakes, are traditional and popular in Asian countries. However, their shelf life is short, primarily due to microbial spoilage. Current manufacturing methods address this ... 
Unlocking datasets by calibrating populations of models to data density: a study in atrial electrophysiology
(Science Advances, 20180110)The understanding of complex physical or biological systems nearly always requires a characterization of the variability that underpins these processes. In addition, the data used to calibrate these models may also often ... 
Uncertainty on radiation doses estimated by biological and retrospective physical methods
(Radiation Protection Dosimetry, 20170918)Biological and physical retrospective dosimetry are recognised as key techniques to provide individual estimates of dose following unplanned exposures to ionising radiation. Whilst there has been a relatively large amount ... 
An exact goodnessoffit test based on the occupancy problems to study zeroinflation and zerodeflation in biological dosimetry data
(Radiation Protection Dosimetry, 20180112)The goal in biological dosimetry is to estimate the dose of radiation that a suspected irradiated individual has received. For that, the analysis of aberrations (most commonly dicentric chromosome aberrations) in scored ... 
Cancer incidence among children and young adults who have undergone xray guided cardiac catheterization procedures
(European Journal of Epidemiology, 20180118)Children and young adults with heart disease appear to be at increased risk of developing cancer, although the reasons for this are unclear. A cohort of 11,270 individuals, who underwent cardiac catheterizations while aged ... 
On the estimation of variance parameters in nonstandard generalised linear mixed models: Application to penalised smoothing
(20180124)We present a novel method for the estimation of variance parameters in generalised linear mixed models. The method has its roots in Harville (1977)'s work, but it is able to deal with models that have a precision matrix ... 
An even simpler understanding of quantum weak values
(Annals of Physics, 201801)We explain the properties and clarify the meaning of quantum weak values using only the basic notions of elementary quantum mechanics. 
Wildland fire propagation modeling: firespotting parametrisation and energy balance
(Proceedings of the 17th International Conference on Computational and Mathematical Methods in Science and Engineering, CMMSE 2017, pp. 805  813, 20170704)Present research concerns the physical background of a wildfire propagation model based on the split of the front motion into two parts  drifting and fluctuating. The drifting part is solved by the level set method and ...
