“…We present a new recovery analysis for a standard compressed sensing algorithm, Iterative Hard Thresholding (IHT) (Blumensath and Davies, 2008), which considers the fixed points of the algorithm. …”

The Impact of Parental Death on Child Outcomes: Evidence from Ethiopia. by Camfield, L, Himaz, R, Murray, H

“…If a parent dies early on in a child’s life (between ages 0 and 6) then the death per se does not seem to affect children’s health, education, sense of optimism or self-esteem at age 12, in part due to the fact that younger children are more likely to be absorbed into the care of close relatives. …”

Informing transport health impact assessment in London by Watkiss, P, Brand, C, Hurley, F, Pilkington, A, Mindell, J, Joffe, M, Anderson, R

“…It focuses on assessing and evaluating the more direct impacts of transport and health, where health is defined in its widest sense as a state of physical, mental and social well-being. …”

A robust a posteriori estimator for the residual-free bubbles method applied to advection-diffusion problems by Sangalli, G

“…The robustness is investiged, in the sense that we prove uniform equivalence between a norm of the numerical residual and a particular norm of the error.…”

Minimal Memory Automata by Benedikt, M, Ley, C, Puppis, G

“…We then show that this canonical automaton is minimal in a strong sense: it has the minimal number of control states and also the minimal amount of internal storage. …”

Multi-Adaptive Error Control for ODEs by Logg, A

“…The method is multi-adaptive in the sense that the timesteps for the different components are chosen individually and adaptively, as based on an a posteriori estimate of the maximum global error. …”

A posteriori error analysis for stabilised finite element approximations of transport problems by Houston, P, Rannacher, R, Suli, E

“…We show both analytically and through numerical experiments that the second approach is superior in the sense that it leads to sharper a posteriori error bounds and more economical adaptively refined meshes.…”

Parameter Synthesis for Probabilistic Timed Automata Using Stochastic Game Abstractions by Jovanovic, A, Kwiatkowska, M

“…We propose a method to synthesise optimal values of timing parameters for probabilistic timed automata, in the sense that the prob- ability of reaching some set of states is either maximised or minimised. …”

Diagonal Dominance and Positive Definiteness of Upwind Approximations for Advection Diffusion Problems by Golub, G, Silvester, D, Wathen, A

“…In addition his generous spirit has infused our discipline with a sense of positive endeavour.…”

The power of social media as a labour campaigning tool: lessons from OUR Walmart and the Fight for 15 by Pasquier, V, Wood, A

“…Social media can invigorate union campaign organising by facilitating workers' involvement in three main ways: by strengthening a sense of collective identity among dispersed workforces, by aggregating feelings of injustice and by enabling self-organised workers practical and emotional support. …”

Collaborative research for a changing climate: learning from researchers and stakeholders in the ARCC programme. by Lonsdale, K, Goldthorpe, M

“…Through interviews and discussions with researchers and stakeholders, the project drew out key messages from the project teams’ experiences and reflections on working together: what supports good collaboration; what gets in the way; how to bring together and make sense of different types of information (e.g. technical, risk based, experiential and values) and communicate complex terms such as uncertainty and risk. …”

Information inequality in the UK coronavirus communications crisis by Fletcher, R, Kalogeropoulos, A, Simon, F, Nielsen, R

“…In this report, which describes the results of six online panel surveys of UK respondents fielded from mid-April to late June 2020, we find that: (i) COVID-19 news use has declined significantly from mid-April to late June, (ii) and as news use has fallen, inequalities in COVID-19 news use have grown (in the sense that news use has become unevenly distributed). …”

Finite element analysis of Cauchy-Born approximations to atomistic models by Makridakis, C, Suli, E

“…These intermediate models can be seen as first level atomistic/quasicontinuum approximations in the sense that they involve only short-range interactions. …”
