Flow structure and unsteady characteristics of fountain flow induced by dual impinging jets
The flow-field structure and mechanical characteristics of dual impinging jets are critical issues during the takeoff and landing phases of aircraft. However, the unsteady characteristics of the fountain effect induced by dual impinging jets have not yet

DTI denoising for data with low signal to noise ratios [PDF]
Low signal to noise ratio (SNR) experiments in diffusion tensor imaging (DTI) give key information about tracking and anisotropy, e. g., by measurements with small voxel sizes or with high b values.

Low-Noise Techniques in Detectors [PDF]
We concentrate in this review on the fundamentals of low-noise techniques and on understanding the limits in the charge signal measurements. Charge collection and signal formation in detectors, the origin and properties of noise, noise and amplification of charge, and detectors and signal processing are discussed. (AIP)

Analysis and Optimization of Noise Response for Low-Noise CMOS Image Sensors [PDF]
CMOS image sensors are nowadays widely used in imaging applications and particularly in low light flux applications. This is really possible thanks to a reduction of noise obtained, among others, by the use of pinned photodiode associated with a ...

Design and analysis strategies for robust microbiome ageing research
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an
