Length-weight relationships of the anchoveta, Cetengraulis mysticetus, in the Gulf of Panama [PDF]
, 1965 ENGLISH: Knowledge of the length-frequency distribution and the length-weight relationships of the anchoveta is essential for converting the catch statistics of that species from pounds to numbers of fish. Such conversions are necessary for various types

Global regulation of robots using only position measurements [PDF]
, 1992 In this note we propose a simple solution to the regulation problem of rigid robots based on the availability of only joint position measurements. The controller consists of two parts: (1) a gravitation compensation, (2) a linear dynamic first-order ...

4D Printing of Multimaterial Flexible Magneto‐Active Polymers
Advanced Materials Technologies, Volume 11, Issue 9, 6 May 2026.Magneto‐active polymers are 3D‐printed with tunable mechanical and magnetic properties using both superparamagnetic and hard ferromagnetic fillers. Nano‐CT imaging reveals the spatial distribution of particles within the matrix. Programmable magnetization patterns and soft, flexible architectures enable responsive actuation, offering exciting ...

Detection of infalling hydrogen in transfer between the interacting galaxies NGC 5426 and NGC 5427
, 2011 Using velocity tagging we have detected hydrogen from NGC 5426 falling onto its interacting partner NGC 5427. Our observations, with the GHaFaS Fabry-Perot spectrometer, produced maps of the two galaxies in Halpha surface brightness and radial velocity ...
