Recovery in forensic mental health services: a review and meta-ethnography of reported accounts of service user experiences
The ‘Recovery Approach’ is widely regarded as the guiding principle for mental health service delivery in the UK. Forensic services face unique challenges in applying this approach. Numerous studies have explored themes associated with recovery in these settings but it is currently unclear how themes relate to each other.
This study set out to build a theoretical model of service user experiences of recovery in forensic mental health settings. Semi-structured interviews were conducted with sixteen service users about their experience of recovery. Grounded Theory methodology, with a constructivist epistemology, was used to analyse the interview data. A cyclical model was developed, with five core recovery processes that inter-related; these were: the environment, connectedness, hope for the future, who I am and empowerment. These occurred in three phases of 1) feeling safe and secure, 2) moving forwards, and 3) empowerment. These processes were encompassed by two additional themes of arriving at hospital and changes over time.
This study is the first to provide a clear model of service user experiences of recovery in this setting. Clinical and research implications are discussed

Titanium honeycomb structure
A brazed titanium honeycomb sandwich system for supersonic transport wing cover panels provides the most efficient structure spanwise, chordwise, and loadwise. Flutter testing shows that high wing stiffness is most efficient in a sandwich structure. This structure also provides good thermal insulation if liquid fuel is carried in direct contact with the wing structure in integral fuel tanks
Development of a non-linear simulation for generic hypersonic vehicles - ASUHS1
A nonlinear simulation is developed to model the longitudinal motion of a vehicle in hypersonic flight. The equations of motion pertinent to this study are presented. Analytic expressions for the aerodynamic forces acting on a hypersonic vehicle which were obtained from Newtonian Impact Theory are further developed. The control surface forces are further examined to incorporate vehicle elastic motion. The purpose is to establish feasible equations of motion which combine rigid body, elastic, and aeropropulsive dynamics for use in nonlinear simulations. The software package SIMULINK is used to implement the simulation. Also discussed are issues needing additional attention and potential problems associated with the implementation (with proposed solutions)
Families of Linear Efficiency Programs based on Debreu's Loss Function
Gerard Debreu introduced a well known radial efficiency measure which he called a “coefficient of resource utilization.†He derived this scalar from a much less well known “dead loss†function that characterizes the monetary value sacrificed to inefficiency, and which is to be minimized subject to a normalization condition. We use Debreu’s loss function, together with a variety of normalization conditions, to generate several popular families of linear efficiency programs. Our methodology also can be employed to generate entirely new families of linear efficiency programs.

‘My journey through the system’: a grounded theory of service user-perceived experiences of recovery in forensic mental health services

Nanosecond channel-switching exact optical frequency synthesizer using an optical injection phase-locked loop (OIPLL)
Experimental results are reported on an optical frequency synthesizer for use in dynamic dense wavelength-division-multiplexing networks, based on a tuneable laser in an optical injection phase-locked loop for rapid wavelength locking. The source combines high stability (50 dB), narrow linewidth (10 MHz), and fast wavelength switching (<10 ns)
