Calculations of Magnetic Exchange Interactions in Mott--Hubbard Systems

An efficient method to compute magnetic exchange interactions in systems with strong correlations is introduced. It is based on a magnetic force theorem which evaluates linear response due to rotations of magnetic moments and uses a novel spectral density functional framework combining our exact diagonalization based dynamical mean field and local density functional theories. Applications to spin waves and magnetic transition temperatures of 3d metal mono--oxides as well as high--T_{c} superconductors are in good agreement with experiment

Comorbid disease and ethnicity in emergency hospital admissions in east London

Statistical Analysis Plan – This aim of this comparative study is to determine in a cohort of non-COVID emergency hospital admissions within the same representative population in east London, whether there is a difference in outcomes in patients of different ethnicities. It will test the hypothesis that patients of Black, Asian and other ethnicities have poorer outcomes defined using mortality and length of stay. Data generated has the potential to influence and shape relevant policy and practice to improve health outcomes in BAME communities

Acute Kidney Injury in COVID-19: secondary analysis of prospective data from the EthICAL study

Statistical Analysis Plan – This secondary analysis of the EthICAL study will focus on the incidence, risk factors and outcomes associated with AKI within COVID-19 patients admitted to five acute hospitals in East London. We will also examine follow-up data to investigate what proportion of COVID-19 patients who developed an AKI never recovered their renal function and progressed to chronic kidney disease (CKD)
