On the Convergence of Conjugate Gradient and GMRES Algorithms in the Forward Backward Sweep Method for Optimal Control

open access: yesOptimal Control Applications and Methods, EarlyView.
Optimal control combines state and adjoint equations, which yield the state (x$$ x $$) and adjoint (lambda) variables as a function of the control variables (u$$ u $$). This structure allows us to design strategies for iteratively updating the control variable, based on conjugate gradient (CG) or GMRES algorithms.

Prevalence and Spirometric Transitions of PRISm and Obstruction: A Population‐Based Study

open access: yesRespirology, EarlyView.
ABSTRACT Background and Objective This study aims to assess the prevalence and longitudinal transitions of spirometric patterns defined by the lower limit of normal (LLN) criteria: normal airflow (FEV1/FVC≥LLN, FEV1 ≥ LLN); preserved ratio impaired spirometry (PRISm; FEV1/FVC≥LLN, FEV1 < LLN); or obstruction (FEV1/FVC

Maximising Participation in the Australian National Lung Cancer Screening Program: A Discrete Choice Experiment of Eligible, High‐Risk Individuals

open access: yesRespirology, EarlyView.
A discrete choice experiment of lung cancer screening attributes. Study results demonstrate that lung cancer screening uptake could be significantly increased by offering program navigators and personalised invitations. The findings contribute significant insights to inform future improvements to the design and implementation of the Australian National

Epigenetic Dysregulation of the NKX2‐1/SPDEF Axis Drives Persistent Goblet Cell Differentiation and Epithelial Barrier Dysfunction in Chronic Obstructive Pulmonary Disease

open access: yesRespirology, EarlyView.
This study investigated airway epithelial barrier dysfunction persistence in ex‐smokers with COPD and underlying mechanisms using single‐cell RNA and ATAC sequencing. Epigenetic NKX2‐1/SPDEF dysregulation maintains goblet cell hyperplasia and barrier dysfunction despite long‐term smoking cessation.
