Abstract

We discuss some fundamental characteristics of a phase-modulating device suitable to holographically project a monochrome video frame with 1280 x 720 resolution. The phase-modulating device is expected to be a liquid crystal over silicon chip with silicon area similar to that of commercial devices. Its basic characteristics, such as number of pixels, bits per pixel, and pixel dimensions, are optimized in terms of image quality and optical efficiency. Estimates of the image quality are made from the noise levels and contrast, while efficiency is calculated by considering the beam apodization, device dead space, diffraction losses, and the sinc envelope. OCIS codes: 090.2870, 090.1760, 090.5694, 160.3710.

Abstract

INTRODUCTION: Postoperative morbidity and mortality in older patients with comorbidities undergoing gastrointestinal surgery are a major burden on healthcare systems. Infections after surgery are common in such patients, prolonging hospitalisation and reducing postoperative short-term and long-term survival. Optimal management of perioperative intravenous fluids and inotropic drugs may reduce infection rates and improve outcomes from surgery. Previous small trials of cardiac-output-guided haemodynamic therapy algorithms suggested a modest reduction in postoperative morbidity. A large definitive trial is needed to confirm or refute this and inform widespread clinical practice. METHODS: The Optimisation of Perioperative Cardiovascular Management to Improve Surgical Outcome II (OPTIMISE II) trial is a multicentre, international, parallel group, open, randomised controlled trial. 2502 high-risk patients undergoing major elective gastrointestinal surgery will be randomly allocated in a 1:1 ratio using minimisation to minimally invasive cardiac output monitoring to guide protocolised administration of intravenous fluid combined with low-dose inotrope infusion, or usual care. The trial intervention will be carried out during and for 4 hours after surgery. The primary outcome is postoperative infection of Clavien-Dindo grade II or higher within 30 days of randomisation. Participants and those delivering the intervention will not be blinded to treatment allocation; however, outcome assessors will be blinded when feasible. Participant recruitment started in January 2017 and is scheduled to last 3 years, within 50 hospitals worldwide. ETHICS/DISSEMINATION: The OPTIMISE II trial has been approved by the UK National Research Ethics Service and has been approved by responsible ethics committees in all participating countries. The findings will be disseminated through publication in a widely accessible peer-reviewed scientific journal. TRIAL REGISTRATION NUMBER: ISRCTN39653756.

Abstract

The contrast ratio and the speed of a 16 x 16 electrically addressed spatial light modulator, composed of a ferroelectric liquid-crystal layer on top of a VLSI silicon backplane, are measured with different methods but consistent results. The results are presented and compared with recently reported results on a similar spatial light modulator [Appl. Opt. 33, 2775 (1994)]. Key words: Electrically addressed spatial light modulator, ferroelectric liquid crystal.

Abstract

An important device for optoelectronic neural networks is a two-dimensional nonlinear thresholding element that is optically written and optically read. The liquid-crystal light valve is the only commercially available device that is suitable for this application. Three different types of valve are analyzed with respect to their suitability for two different types of neural network.

Abstract

BACKGROUND: D-Cycloserine has potential to enhance exposure therapy outcomes. The current study presents a preliminary randomized, placebo-controlled double-blind pilot trial of DCS-augmented one-session treatment (OST) for youth (7-14 years) with specific phobia. A secondary aim of this pilot study was to explore the effects of youth age and within-session fear reduction as potential moderators of DCS outcomes in order to generate hypotheses for a larger trial. It was hypothesized that DCS would be associated with greater improvements than placebo, that children (7-10 years) would have greater benefits than adolescents (11-14 years), and that DCS effects would be stronger for participants with the greater within-session fear reduction during the OST. METHODS: Thirty-five children and adolescents were randomized to either OST combined with DCS (n = 17), or OST combined with placebo (PBO; n = 18) and assessed at 1 week, 1 month, and 3 month following treatment. RESULTS: There were no significant pre- to post-treatment or follow-up benefits of DCS relative to placebo. Secondary analyses of age indicated that relative to PBO, DCS was associated with greater improvements for children (but not adolescents) on measures of severity at 1-month follow-up. Children in the DCS condition also showed significantly greater improvement to 1 month on global functioning relative to other groups. Conversely, adolescents had significant post-treatment benefits in the PBO condition on symptom severity measures relative to DCS, and adolescents in the DCS condition had significantly poorer functioning at 3 months relative to all other groups. Finally, there was a trend for within-session fear reduction to be associated with moderating effects of DCS, whereby greater reduction in fear was associated with greater functioning at one-month follow-up for children who received DCS, relative to PBO. LIMITATIONS: The study sample was small and therefore conclusions are tentative and require repl

Abstract

This work presents the measurement of the dielectric anisotropy of selected nematic liquid crystals in the 0.01–6 GHz range, and comparison of the measurements with the birefringence values at optical frequencies. The effect of alignment on the reproducibility of dielectric measurements was also measured. It was found that a good surface alignment is essential to achieve reproducibility. Finally, it was experimentally confirmed that there is a strong correlation between the dielectric anisotropy in the microwave region and the birefringence at visible frequencies.

Abstract

Background: This study examined the feasibility and preliminary effectiveness of d-cycloserine (DCS)–augmented cognitive behavioral therapy (CBT) for children and adolescents with difficult-to-treat Obsessive Compulsive Disorder, in a double-blind randomized controlled pilot trial (RCT).Methods: Seventeen children and adolescents (aged 8–18 years) with a primary diagnosis of OCD, which was deemed difficult-to-treat, were randomly assigned to either nine sessions of CBT including five sessions of DCS-augmented exposure and response prevention (ERP) [ERP + DCS] or nine sessions of CBT including five sessions of placebo-augmented ERP [ERP + PBO]. Weight-dependent DCS or placebo doses (25 or 50 mg) were taken 1 hour before ERP sessions.Results: At post treatment, both groups showed significant improvements with 94% of the entire sample classified as responders. However, a greater improvement in the ERP + DCS relative to the ERP + PBO condition was observed at 1-month follow-up on clinician-rated obsessional severity and diagnostic severity, and parent ratings of OCD severity. There were no changes across time or condition from 1- to 3-month follow-up.Conclusions: In this preliminary study, DCS-augmented ERP produced significant improvements in OCD severity from posttreatment to 1-month follow-up, relative to a placebo control condition, in severe and difficult-to-treat pediatric OCD. The significant effect on obsessional severity suggests that DCS augmentation might be associated with enhanced modification of obsessional thoughts during ERP, and warrants further investigation.

40. Compact correlator based on a holographic memory: limitations due to current LCTV technology

Author

Duelli, M., Pourzand, A.R., Collings, N., and Dändliker, R.

Abstract

A hybrid digital/optical correlator system has been built that performs pure phase correlation[1]. The pure phase correlation[2] uses only the phase information of the object and template, i.e. it takes the phase distribution of the Fourier transform of the object to be recognised and it correlates it with the phase-only filter (POF) defined by Homer[3]. This type of correlator shows sharp correlation peaks, a high light efficiency, and a high discrimination capability.
