Image denoising with multi-layer perceptrons, part 1: comparison with existing algorithms and with bounds [PDF]

, 2012
Image denoising can be described as the problem of mapping from a noisy image to a noise-free image. The best currently available denoising methods approximate this mapping with cleverly engineered algorithms.

Laplacian growth with separately controlled noise and anisotropy

, 2001
Conformal mapping models are used to study competition of noise and anisotropy in Laplacian growth. For that, a new family of models is introduced with the noise level and directional anisotropy controlled independently.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Conscious walk assessment for the joint evaluation of the soundscape, air quality, biodiversity, and comfort in Barcelona

Noise Mapping
High environmental noise as well as poor biodiversity and air pollution pose significant challenges for the European population, particularly those residing in urban areas, impacting clearly on citizens’ health.

Urban Background Noise Mapping: The General Model [PDF]

Acta Acustica united with Acustica, 2014
Surveys show that inhabitants of dwellings exposed to high noise levels benefit from having access to a quiet side. However, current practice in noise prediction often underestimates the noise levels at a shielded façade. Multiple reflections between façades in street canyons and inner yards are commonly neglected and façades are approximated as ...

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

The Environment (Air Quality and Soundscapes) (Wales) Act 2024

Noise Mapping
The Welsh Government’s policy on noise and soundscape is underpinned by two key pieces of legislation: the Well-being of Future Generations (Wales) Act 2015, and the Environment (Air Quality and Soundscapes) (Wales) Act 2024.

Towards Mapping of Noise Impact [PDF]

, 2022
AbstractNoise impact management goes hand in hand with the capability to predict the noise impact on exposed communities. Three tools to that purpose are presented in this chapter: the Noise Management Toolset (NMT), the Demo Virtual Community Tool (VCT) and Dynamic Noise Mapping.

Evanescent-wave Johnson Noise in small devices

, 2017
In many quantum computer architectures, the qubits are in close proximity to metallic device elements. The fluctuating currents in the metal give rise to noisy electromagnetic fields that leak out into the surrounding region.
