Reconstruction of piano hammer force from string velocity [PDF]
The Journal of the Acoustical Society of America, 2016 A method is presented for reconstructing piano hammer forces through appropriate filtering of the measured string velocity. The filter design is based on the analysis of the pulses generated by the hammer blow and propagating along the string. In the five lowest octaves, the hammer force is reconstructed by considering two waves only: the incoming wave

High-velocity string of knots in the outburst of the planetary nebula Hb4 [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 The bipolar collimated outflows of the Hb4 Planetary Nebula (PN) exhibit an evident decrease in their expansion velocity with respect to the distance from the central star. So far, similar velocity law has also been found in Herbig-Haro objects. The interpretation of this peculiar velocity law and the classification of the outflows is the main focal ...

Casting behavior of the string structures considering axial elongation
Nihon Kikai Gakkai ronbunshu, 2019 A flexible string is used at various places. Typical examples are a cable for power transmission and communication and a wire for cranes and elevators. In addition, there are the uses such as a fly-fishing line, climbing rope and a mowing machine to cut ...

Influence of Coiled Tubing Size and Lowering Depth on Velocity String Operation
Shiyou jixie, 2020 Aiming to resolve the problem of liquid loading at the well bottom during gas well production and increase the well production by installing coiled tubing as a velocity string, a study on the influence of coiled tubing size and lowering depth on velocity

Neutrino currents in wakes of cosmic strings
European Physical Journal C: Particles and Fields, 2020 Neutrinos rotating around Abelian Higgs strings will generate a neutral current close to the string. As the string moves through the cosmic plasma, the velocity kick generated by the motion of the string will enhance the neutrino current in the wake ...

Large-scale peculiar velocities from cosmic strings [PDF]
Nature, 1987 Recent observations1–3 indicate that large regions of the Universe 60 h−1 Mpc in radius (where h is the Hubble constant in units of 100 km s−1 Mpc−1) may be streaming coherently with velocities up to 1,000 km s−1 with respect to the rest frame determined by the cosmic microwave background.

Finding novel vulnerabilities of hypomorphic BRCA1 alleles
Molecular Oncology, EarlyView.Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have

A Knowledge‐Based Approach for Understanding and Managing Additive Manufacturing Data
Advanced Engineering Materials, EarlyView.Additive manufacturing processes generate a large amount of data. Effectively managing, understanding, and retrieving information from this data remains a major challenge. Therefore, we propose an ontology‐based approach to integrate heterogeneous data, enable semantic queries, and support decision‐making.
