Q-switching and mode-locking pulse generation with graphene oxide paper-based saturable absorber

The Journal of Engineering, 2015
Q-switched and mode-locked erbium-doped fibre lasers (EDFLs) are demonstrated by using non-conductive graphene oxide (GO) paper as a saturable absorber (SA).

Polarization‐Dependence of Nonlinear Optical Effects in Silicon: The Case of Ultrafast Processing

Advanced Physics Research, EarlyView.
The dependence of the input polarization for the nonlinear optical propagation in silicon is investigated theoretically and experimentally. The perturbative regime is examined using pump‐probe shadowgraphy and nonlinear transmission, whereas the case of permanent laser‐induced modifications is addressed using a combination of Raman micro‐spectroscopy ...

Three‐dimensional geometric morphometric analysis of diaphragmatic dome motion in COPD patients

The Anatomical Record, EarlyView.
Abstract Diaphragmatic dysfunction is a hallmark of chronic obstructive pulmonary disease (COPD), especially in emphysema, where hyperinflation alters diaphragm geometry and impairs inspiratory mechanics. However, quantitative three‐dimensional (3D) assessments of diaphragmatic dome shape and motion across COPD phenotypes are limited.

Lung Ultrasound for the Detection of Radiologic Progression of Interstitial Lung Abnormalities in Patients With Rheumatoid Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Interstitial lung disease (ILD) is an important extra‐articular manifestation of rheumatoid arthritis (RA) associated with high mortality and morbidity. Lung ultrasonography (LUS) has recently emerged as a possible screening tool. We assessed the role of LUS in monitoring radiologic progression and the development of new interstitial lung ...

Expert Perspectives: Defining and Managing Progressive Pulmonary Fibrosis in Systemic Sclerosis

Arthritis &Rheumatology, EarlyView.
Systemic sclerosis–associated interstitial lung disease (SSc‐ILD) is one of the leading causes of morbidity and mortality in SSc, affecting up to three‐quarters of patients. The disease course is highly heterogeneous, ranging from indolent, nonprogressive forms to rapidly progressive pulmonary fibrosis (PPF).

Portopulmonary hypertension practice patterns after liver transplantation

Liver Transplantation, EarlyView., 2022
Abstract Portopulmonary hypertension (POPH) is a type of pulmonary arterial hypertension occurring exclusively in those with portal hypertensive liver disease. Liver transplantation (LT) can significantly improve outcomes. Current guidelines counsel against immediate adjustments to targeted therapy after LT and suggest routine echocardiography as ...

Er:Ta₂O₅ waveguide optimization & spectroscopy

, 2008
The optimization of erbium-doped Ta thin film waveguides deposited by magnetron sputtering is described. Background losses below 0.4dB/cm have been obtained before post-annealing. A broad photoluminescence spectrum centered at 1534nm is obtained, and the

Outcomes in progressive pulmonary fibrosis in systemic autoimmune rheumatic diseases: real‐world data from the ILD‐PRO Registry

Arthritis &Rheumatology, Accepted Article.
Objective We evaluated baseline characteristics, treatment patterns, and outcomes in patients with systemic autoimmune rheumatic disease‐associated progressive pulmonary fibrosis (SARD‐PPF) and evaluated whether outcomes differed by SARD subtype. Methods The ILD‐PRO Registry is a prospective multicenter US registry of patients with PPF.
