Magnetic Field and Torque Output of Packaged Hydraulic Torque Motor
Energies, 2018 Hydraulic torque motors are one key component in electro-hydraulic servo valves that convert the electrical signal into mechanical motions. The systematic characteristics analysis of the hydraulic torque motor has not been found in the previous research,

On the Temperature Dependence of Ferro-Magnetic Saturation [PDF]
Proceedings of the National Academy of Sciences, 1933 Accurate data on the saturation intensity of magnetization at low temperatures for monocrystalline materials were recently published by Allen and Constant(1) who, moreover, show that their results fit into the following interesting law: Let the saturation intensity at the temperature T be denoted by MST, the same intensity at the absolute zero of ...

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network
FEBS Letters, EarlyView.Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.
