Patient involvement in basic rheumatology research at Nijmegen: a three year’s responsive evaluation of added value, pitfalls and conditions for success

BMC Rheumatology, 2022
Background Empirical evidence for effective patient-researcher collaboration in basic research is lacking. This study aims to explore good working models and impact of patient involvement in basic rheumatology research and to identify barriers and ...

A comparison of normobaric and hypobaric hypoxia effects on cerebrovascular response pre and post maximal exercise

Experimental Physiology, Volume 111, Issue 11, Page 5154-5165, 1 November 2026.
Abstract A lack of consensus remains on whether normobaric hypoxia (NH) and hypobaric hypoxia (HH) may differentially impact physiological factors affecting cerebrovascular regulation, particularly with an additional strenuous exercise component. We sought to compare the acute effects of NH and HH on global cerebral blood flow (gCBF) at an altitude ...

Aerosol Retrieval Over Ocean From DPC‐2/GF‐5(02): Using RemoTAP Extended With a 3‐Parameter Ocean Bio‐Optical Model and Comparisons With a 1‐Parameter Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Multi‐angle polarimetric instruments (MAPs) enable the retrieval of essential aerosol properties over oceanic regions. MAPs retrieval algorithms commonly use a 1‐parameter ocean bio‐optical model (OBM), based on chlorophyll‐a concentration only to represent optical properties over open waters (case‐1), whereas the coastal water (mixture of ...

Deterministic-aided single dataset STAP method based on sparse recovery in heterogeneous clutter environments

EURASIP Journal on Advances in Signal Processing, 2018
Traditional space-time adaptive processing (STAP) usually needs many independent and identically distributed (i.i.d) training datasets for estimating clutter covariance matrix (CCM).

Suppression of Jammer Multipath in GNSS Antenna Array Receiver

Remote Sensing, 2022
Interference multipath is an important factor to affect the anti-jamming performance for the global navigation satellite system (GNSS) antenna array receiver. However, interference multipath must be considered in practical application. In this paper, the

How Program‐ and Community‐Led Design Settings Affect Resilience Approaches to Sustainable Development Projects

Sustainable Development, Volume 34, Issue 6, Page 8789-8804, October 2026.
ABSTRACT Sustainable Development interventions must deal with rapid and novel changes affecting complex social‐ecological systems, calling for design based on a resilience approach. However, limited analytical attention has been paid to the design settings in which such approaches are deployed.

FDA-STAP by Shrinkage Algorithm Under Range Ambiguity for Limited Training Samples

IEEE Access
When airborne radar detects targets, space-time adaptive processing (STAP) performs a vital role in clutter rejection. As is known, clutter rejection is limited by range ambiguity.
