Our results support previous research suggesting that cannabinoids are a safe and effective treatment for TS and should be considered in treatment-resistant cases. Further studies are needed to substantiate our findings.
The primary purpose of this article is to review the potential therapeutic value of freely available VR content as an addition to the practitioners ‘toolkit’. Research has shown that virtual reality (VR) may be useful to extend existing guided imagery-based practices found in traditional mental health therapy. However, the use of VR technology within routine mental health practice remains low, despite recent reductions in equipment costs. A systematic scoping review and interdisciplinary analysis of freely available VR experiences was performed across two popular online databases (SteamVR and Oculus.com). A total of 1785 experiences were retrieved and screened for relevance with 46 meeting the inclusion criteria. VR content was then reviewed for potential therapeutic value by an interdisciplinary panel with experience across a number of therapeutic interventions including cognitive behavioural therapy, Rogerian counselling, mindfulness-based therapies. and family therapy. Eleven (22%) of the 50 freely available VR experiences were reported to have therapeutic potential as tools to support routine mental health therapy. These included support with the following mental health issues—low mood, social anxiety, stress reduction and fear of heights. Guidance of a qualified mental health practitioner was recommended in all cases to maximise the benefit of the VR experiences retrieved. While the quality is variable, freely available VR experiences may contain valuable content that could support mental health therapy. This includes as a homework activity or as an initial setting for case formulation and behavioural experiments.
This paper presents a novel FPGA implementation of a two dimensional (8x8) point Discrete Cosine Transform. It is shown how the development of a suitable architectural style can produce high quality circuit designs for a specific technology, in this case the Xilinx XC6200 series of FPGA. Distributed arithmetic and exploitation of parallelism and pipelining are used to produce a DCT implementation on a single FPGA that operates at 25 frames per second with VGA resolution which is the equivalent of 2 million multiplications or additions per second.
Details are presented of the IRIS synthesis system for high-performance digital signal processing. This tool allows non-specialists to automatically derive VLSI circuit architectures from high-level, algorithmic representations, and provides a quick route to silicon implementation. The applicability of the system is demonstrated using the design example of a one-dimensional Discrete Cosine Transform circuit.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
