• Objective: To compare the frequency of injury to clients and staff with use of 2 restraint systems. • Design: Retrospective database review. • Setting and participants: Youth admitted under both voluntary and involuntary commitments to residential behavioral and mental health programs in Pennsylvania and New York and staff from these institutions. • Methods: Restraint events that occurred dur...

I agree with John Southcott's overall premise that training in breakaway skills gives nurses some physical techniques to protect themselves and that this does not preclude them from using physical means of selfprotection (Opinion March 22).

Deformable elastic network (DEN) restraints have proved to be a powerful tool for refining structures from low-resolution X-ray crystallographic data sets. Unfortunately, optimal refinement using DEN restraints requires extensive calculations and is often hindered by a lack of access to sufficient computational resources. The DEN web service presented here intends to provide structural biologis...

Residual dipolar couplings are useful global structural restraints. The dipolar couplings define the orientation of a vector with respect to the alignment tensor. Although the size of the alignment tensor can be derived from the distribution of the experimental dipolar couplings, its orientation with respect to the coordinate system of the molecule is unknown at the beginning of structure deter...

Head direction cells form an internal compass signaling head azimuth orientation even without visual landmarks. This property is generated by a neuronal ring attractor that is updated using rotation velocity cues. The properties and origin of this velocity drive remain, however, unknown. We propose a quantitative framework whereby this drive represents a multisensory self-motion estimate comput...

The practices of seclusion and restraint may be used in a variety of health settings to control behaviour. Laws and policies that seek to regulate these practices define seclusion and restraint in various ways and there are gaps as to which practices are regulated and in what circumstances. This column provides an overview of consumer and carer perspectives as to what is meant by these practices.
