NOISE REDUCTION IN ACOUSTIC DISDROMETRY
8th European Conference on Noise Control 2009, 2023 This paper reports progress on the development of a novel rain disdrometer and the methods of noise reduction. The proposed instrument will measure the raindrop size distribution using the sound generated by raindrops landing in a tank of water. When an incident hydrometeor impacts on the surface of a liquid, two processes create an acoustic signal ...

Noise Reduction of an Axial Piston Pump by Valve Plate Optimization
Chinese Journal of Mechanical Engineering, 2018 Current researches mainly focus on the investigations of the valve plate utilizing pressure relief grooves. However, air-release and cavitation can occur near the grooves. The valve plate utilizing damping holes show excellent performance in avoiding air-

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer
FEBS Letters, EarlyView.Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...

Amplitude noise reduction in semiconductor lasers with weak, dispersive optical feedback [PDF]
, 1994 We present the theory and measurements of the amplitude noise spectrum from a semiconductor laser with weak optical feedback (Pfb/Pout ~10^-6) from an external cavity containing an element of dispersive loss.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
FEBS Letters, EarlyView.Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Noise reduction algorithm for glueball correlators
Physics Letters B, 2014 We present an error reduction method for obtaining glueball correlators from Monte Carlo simulations of SU(3) lattice gauge theory. We explore the scalar and tensor channels at three different lattice spacings.
