Magnetic Properties of Sm-Fe-N/Co-B Composite Magnets Prepared by Chemical Reduction by Tetsuji Saito

“…The Sm-Fe-N/Co-B composite powder acted as a single hard magnetic phase and showed a smooth hysteresis loop. The composite powder exhibited a higher remanence of 93.1 Am2/kg and a higher coercivity of 0.45 MA/m than a mixture of the Sm-Fe-N powder and Co-B powder prepared by a similar procedure but using a higher concentration of aqueous solution for the chemical reduction.…”

Finite-Time Orbit Control for Spacecraft Formation with External Disturbances and Limited Data Communication by Lei Xing, Dechao Ran, Jian Zhang, Li Huang

“…Combined with the adding one power integrator method and backstepping technique, a new finite-time tracking control strategy with adaptation law is designed to ensure that the closed-loop system is practical finite-time stable, and that the tracking errors of relative position and velocity are bounded within finite-time despite with limited data communication and external disturbances. …”

The three-dimensional N $$ \mathcal{N} $$ = 2 superfishnet theory by Moritz Kade

“…We use techniques inspired by the integrability of bi-scalar fishnet theory and adapted to superspace to calculate the zero-mode-fixed thermodynamic free energy, the corresponding critical coupling, and the exact all-loop scaling dimensions of various operators. Furthermore, we confirm the results of the supersymmetric dynamical fishnet theory by applying our methods to four-dimensional N $$ \mathcal{N} $$ = 1 superspace.…”
