Coercion is threat of actions which compels the patient to behave in a manner inconsistent with his own wishes. Coercion is inevitable in psychiatric practices. Various coercive techniques are chemical and physical restraints, seclusion and isolation. This chapter deals with various types of coercive interventions.

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Nb-doping Induced High Coercivity in Pr2Fe14B/α-Fe Nanocomposite Melt-spun Ribbons
The effect of niobium (Nb) doping on the microstructure and magnetic properties of as-spun Pr10Fe82.5-xB6.5Nbx ribbons was investigated. Nb doping significantly refines the grain size and enhances the coercivity, which increases from 380 kA/m (x = 0) to ...

Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics
Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

Multiple solutions for semilinear elliptic boundary value problems at resonance
successful in proving the existence of weak solutions for semilinear elliptic boundary value problems at resonance. One technique involves a variational approach where solutions are characterized as saddle points for a related functional.
