A resolver-to-digital conversion method based on third-order rational fraction polynomial approximation for PMSM control (2018)
Journal Article

—In this paper, a cost-effective and highly accurate resolver-to-digital conversion (RDC) method is presented. The core of the idea is to apply a third-order rational fraction polynomial approximation (TRFPA) for the conversion of sinusoidal signals...

Agency in dementia care: systematic review and meta-ethnography (2018)
Journal Article

Objectives: Dementia often limits the agency of the person to such an extent that there is need for external support in making daily life decisions. This support is usually provided by family members who are sometimes legally empowered to engage i... Read More about Agency in dementia care: systematic review and meta-ethnography.

Formulation of Bioerodible Ketamine Microparticles as an Analgesic Adjuvant Treatment Produced by Supercritical Fluid Polymer Encapsulation (2018)
Journal Article

Pain is inadequately relieved by escalating doses of a strong opioid analgesic such as morphine in up to 25% of patients with cancer-related severe pain complicated by a neuropathic (nerve damage) component. Hence, there is an unmet medical need for...

Computer simulation clarifies mechanisms of carbon dioxide clearance during apnoea (2018)
Journal Article

Background Apnoeic oxygenation can come close to matching the oxygen demands of the apnoeic patient but does not facilitate carbon dioxide (CO2) elimination, potentially resulting in dangerous hypercapnia. Numerous studies have shown that high-flo... Read More about Computer simulation clarifies mechanisms of carbon dioxide clearance during apnoea.

The Three Hundred Project: the evolution of galaxy cluster density profiles (2018)
Journal Article

Recent numerical studies of the dark matter density profiles of massive galaxy clusters (Mhalo > 1015 M) show that their median radial mass density profile remains unchanged up to z > 1, displaying a highly self-similar evolution. We verify this by u... Read More about The Three Hundred Project: the evolution of galaxy cluster density profiles.

A validated analytical-numerical modelling strategy to predict residual stresses in single-track laser deposited IN718 (2018)
Journal Article

Direct Energy Deposition (DED) is being increasingly used to repair high value components that have been damaged in-service. The uptake of DED and laser cladding operations for repair is inhibited by accurate modelling techniques. Often the repair pr...

Production of high purity silica by microfluidic-inclusion fracture using microwave pre-treatment (2018)
Journal Article

© 2018 Demand for high purity silica used in component manufacture is set to outstrip current supply in the near future. As such, alternative processing routes to feed-stock materials suitable for use in lighting and solar cell fabrication are requir...

Treatment-resistant and multi-therapy-resistant criteria for bipolar depression: consensus definition (2018)
Journal Article

© The Royal College of Psychiatrists 2018. Background Most people with bipolar disorder spend a significant percentage of their lifetime experiencing either subsyndromal depressive symptoms or major depressive episodes, which contribute greatly to th...

A study of tuberculosis in road traffic-killed badgers on the edge of the British bovine TB epidemic area (2018)
Journal Article

The role of badgers in the geographic expansion of the bovine tuberculosis (bTB) epidemic in England is unknown: indeed there have been few published studies of bTB in badgers outside of the Southwest of England where the infection is now endemic in...

Looking Through Dementia: What Do Commercial Stock Images Tell Us About Aging and Cognitive Decline? (2018)
Journal Article

Commercial stock images are existing, artificially-constructed visuals used by businesses and mass media outlets to articulate certain values, assumptions and beliefs. Despite their pervasiveness and ready accessibility, little is known about the way...
