Outcomes and characteristics of COVID-19 patients treated with continuous positive airway pressure/high-flow nasal oxygen outside the intensive care setting

open access: yesERJ Open Research, 2021
Background Continuous positive airway pressure (CPAP) and high-flow nasal oxygen (HFNO) have been used to manage hypoxaemic respiratory failure secondary to coronavirus disease 2019 (COVID-19) pneumonia.

Developing and testing the ExerciseGuide UK website for people with lung cancer: reflections on the added value of patient and public involvement within a doctoral degree

open access: yesResearch Involvement and Engagement, 2022
Plain English summary This commentary describes how patient public involvement has been used to adapt a website called ExerciseGuide UK. This website provides a personalised physical activity program and education to those diagnosed with lung cancer. The

Is a staged reloading protocol effective to time the removal of circular frames?: a retrospective analysis

open access: yesBone & Joint Open, 2022
Aims: The timing of when to remove a circular frame is crucial; early removal results in refracture or deformity, while late removal increases the patient morbidity and delay in return to work.

Exhibition: Sea of Hull [PDF]

open access: yesBritish Journal of General Practice, 2017
Hull, 9 July 2016 (City of Culture 2017). Part of the free exhibition, SKIN, the Ferens Gallery, Hull , 22 April–13 August 2017. It’s been a while since I last wandered around a city centre at three in the morning (and I am not sure I have ever done it sober), but last July I was walking with over 3000 others into the middle of Hull.

On Sumsets and Convex Hull [PDF]

open access: yesDiscrete & Computational Geometry, 2014
One classical result of Freimann gives the optimal lower bound for the cardinality of A+A if A is a d-dimensional finite set in the Euclidean d-space. Matolcsi and Ruzsa have recently generalized this lower bound to |A+kB| if B is d-dimensional, and A is contained in the convex hull of B.

Set Estimation Under Biconvexity Restrictions

open access: yes, 2020
A set in the Euclidean plane is said to be biconvex if, for some angle $\theta\in[0,\pi/2)$, all its sections along straight lines with inclination angles $\theta$ and $\theta+\pi/2$ are convex sets (i.e, empty sets or segments). Biconvexity is a natural

The Gauged (2,1) Heterotic Sigma-Model [PDF]

open access: yes, 1997
The geometry of (2,1) supersymmetric sigma-models with isometry symmetries is discussed. The gauging of such symmetries in superspace is then studied.

A New Method for Constructing Self-Dual Codes over Finite Commutative Rings with Characteristic 2

open access: yesMathematics
In this work, we present a new method for constructing self-dual codes over finite commutative rings R with characteristic 2. Our method involves searching for k×2k matrices M over R satisfying the conditions that its rows are linearly independent over R

Actions For (2,1) Sigma-Models and Strings [PDF]

open access: yes, 1997
Effective actions are derived for (2,0) and (2,1) superstrings by studying the corresponding sigma-models. The geometry is a generalisation of Kahler geometry involving torsion and the field equations imply that the curvature with torsion is self-dual in
