The University of Surrey is a public research university located within the county town of Guildford, Surrey, in the South East of England, United Kingdom. The university specializes in science, engineering, medicine and business. It received its charter on 9 September 1966, and was previously situated near Battersea Park in south-west London. The institution was known as Battersea College of Technology before gaining university status. Its roots however go back to the Battersea Polytechnic Institute, founded in 1891 to provide further and higher education for London's poorer inhabitants.The university conducts extensive research on small satellites and has a high number of staff who are members of learned societies. The university has recently expanded into China by launching the Surrey International Institute with Dongbei University of Finance and Economics.The university's main campus is located on Stag Hill close to the centre of Guildford and adjacent to Guildford Cathedral. A second campus, at Manor Park, is located a short distance away and has been developed to expand upon existing accommodation, academic buildings and sporting facilities.The university is a major centre for satellite and mobile communications research. Recently, the British Prime Minister David Cameron announced a partnership between the University of Surrey, King's College London and the University of Dresden for the development of 5G technology.The university is a member of the Association of MBAs, the European University Association and Association of Commonwealth Universities. In tabloid magazine rankings, the University is ranked high consistently across The Times, the Guardian and the Sunday Times. According to the figures revealed by Higher Education Statistics Agency in 2014, the University of Surrey has the highest graduate employment rates recorded at a 96.9% beating the likes of Oxford University , University of Cambridge and King's College London .The university has 10 Fellows of the Royal Society, 21 Fellows of the Royal Academy of Engineering, one Fellow of the British Academy and 6 Fellows of the Academy of Social science.

Charron and co-authors propose the preservation of tensor covariance as the criterion for dynamically consistent approximation of the governing equations for global atmospheric and oceanographic flow. Earlier criteria, based on vector differential analysis, involve the preservation of individual conservation properties. Here, the two approaches are compared for the interested, but possibly perplexed, reader. Differences regarding terminology and some consistency issues relating to certain 'quasi-shallow' models are discussed. However, the overall similarity of the results of the two approaches and of the variational approach using Hamilton's principle of least action is evident. Relevant aspects of an approximate global model that uses an analytically tractable ellipsoidal geopotential coordinate system are also discussed. © 2015 Royal Meteorological Society. Source

Background:Sociodemographic inequalities in the stage of diagnosis and cancer survival may be partly due to differences in the appraisal interval (time from noticing a bodily change to perceiving a reason to discuss symptoms with a health-care professional). A number of symptom appraisal models have been developed describing the psychological factors that underlie how people make sense of symptoms, although none explicitly focus on sociodemographic characteristics.Methods:We therefore conducted a conceptual review synthesising all symptom appraisal models, and focus on potential links with sociodemographics that could be the focus of future research.Results:Common psychological elements across nine symptom appraisal models included knowledge, attention, expectation and identity, all of which could be sensitive to sociodemographic factors. For example, lower socioeconomic status (SES), male sex and older age are associated with lower health literacy generally and lower cancer symptom knowledge. Limited attentional resources, lower expectations about health and lack of social support also hamper symptom interpretation, and would be likely to be more prevalent in those from lower SES backgrounds. Symptom heuristics (‘rules of thumb’) may lead to symptoms being normalised because they are common within the social network, potentially disadvantaging older populations.Conclusions:A better understanding of the processes through which people interpret their symptoms, and the way these processes differ by sociodemographic factors, could help guide the development of interventions with the aim of reducing inequalities in cancer outcomes.British Journal of Cancer advance online publication, 3 March 2015; doi:10.1038/bjc.2015.39 www.bjcancer.com. © 2015 Cancer Research UK Source

I review current efforts to measure the mean density of dark matter near the Sun. This encodes valuable dynamical information about our Galaxy and is also of great importance for 'direct detection' dark matter experiments. I discuss theoretical expectations in our current cosmology; the theory behind mass modelling of the Galaxy; and I show how combining local and global measures probes the shape of the Milky Way dark matter halo and the possible presence of a 'dark disc'. I stress the strengths and weaknesses of different methodologies and highlight the continuing need for detailed tests on mock data - particularly in the light of recently discovered evidence for disequilibria in the Milky Way disc. I collate the latest measurements of ρdm and show that, once the baryonic surface density contribution Σb is normalized across different groups, there is remarkably good agreement. Compiling data from the literature, I estimate Σb = 54.2 ±4.9 Mȯpc-2, where the dominant source of uncertainty is in the Hi gas contribution. Assuming this contribution from the baryons, I highlight several recent measurements of ρdm in order of increasing data complexity and prior, and, correspondingly, decreasing formal error bars. Comparing these measurements with spherical extrapolations from the Milky Way's rotation curve, I show that the Milky Way is consistent with having a spherical dark matter halo at R0 ∼ 8 kpc. The very latest measures of ρdm based on ∼10000 stars from the Sloan Digital Sky Survey appear to favour little halo flattening at R0, suggesting that the Galaxy has a rather weak dark matter disc, with a correspondingly quiescent merger history. I caution, however, that this result hinges on there being no large systematics that remain to be uncovered in the SDSS data, and on the local baryonic surface density being Σb ∼ 55 Mȯpc-2. I conclude by discussing how the new Gaia satellite will be transformative. We will obtain much tighter constraints on both Σb and ρdm by having accurate 6D phase space data for millions of stars near the Sun. These data will drive us towards fully three dimensional models of our Galactic potential, moving us into the realm of precision measurements ofρdm. © 2014 IOP Publishing Ltd. Source

In papers on cold field electron emission from large-area field emitters (LAFEs), it has become widespread practice to publish a misleading FowlerNordheim-type (FN-type) equation. This equation over-predicts the LAFE-average current density by a large highly variable factor thought to usually lie between 10 3 and 10 9. This equation, although often referenced to FNs 1928 paper, is a simplified equation used in undergraduate teaching, does not apply unmodified to LAFEs and does not appear in the 1928 paper. Technological LAFE papers often do not cite any theoretical work more recent than 1928, and often do not comment on the discrepancy between theory and experiment. This usage has occurred widely, in several high-profile American and UK applied-science journals (including Nanotechnology), and in various other places. It does not inhibit practical LAFE development, but can give a misleading impression of potential LAFE performance to non-experts. This paper shows how the misleading equation can be replaced by a conceptually complete FN-type equation that uses three high-level correction factors. One of these, or a combination of two of them, may be useful as an additional measure of LAFE quality; this paper describes a method for estimating factor values using experimental data and discusses when it can be used. Suggestions are made for improved engineering practice in reporting LAFE results. Some of these should help to prevent situations arising whereby an equation appearing in high-profile applied-science journals is used to support statements that an engineering regulatory body might deem to involve professional negligence. © 2012 IOP Publishing Ltd.
