An electrically addressed liquid crystal Fourier plane filter capable of real time optical image processing is described. The filter consists of two parts: a wedge filter having forty 9 deg segments and a ring filter having twenty concentric rings in a one inch diameter active area. Transmission of the filter in the off (transparent) state exceeds fifty percent. By using polarizing optics, contrast as high as 10,000:1 can be achieved at voltages compatible with FET switching technology. A phenomenological model for the dynamic scattering is presented for this special case. The filter is designed to be operated from a computer and is addressed by a seven bit binary word which includes an on or off command and selects any one of the twenty rings or twenty wedge pairs. The overall system uses addressable latches so that once an element is in a specified state, it will remain there until a change of state command is received. The drive for the liquid crystal filter is ? 30 V peak at 30 Hz to 70 Hz. These parameters give a rise time for the scattering of 20 msec and a decay time of 80 to 100 msec.

- Abstract
The use of randomized clinical trials, in particular placebo-controlled trials, for drug approval, is the subject of long-standing debate in the scientific community and beyond. This study offers consensus recommendations from clinical and academic experts to guide the selection of clinical trial design in psychiatry. Forty-one highly cited clinical psychiatrists and/or researchers participated in a Delphi survey. Consensus statements were developed based on the findings of a published, peer-reviewed systematic review. Participants evaluated statements in two survey rounds, following the Delphi method. The expert panel achieved consensus on 7 of 21 recommendations regarding the use of randomized clinical trials. The endorsed recommendations were: (i) Results from placebo-controlled trials are the most reliable and (ii) are necessary despite the growing placebo-effect; (iii) it is ethical to enroll patients in placebo-arms when established treatment is available, if there is no evidence of increased health risk; (iv) There is a need to approve new drugs with the same efficacy as existing treatments, but with different side-effect profiles; (v) Non-inferiority trials incur an increased risk of approving ineffective medications; (vi) The risk of approving an ineffective drug justifies trial designs that incur higher costs, and (vii) superiority trials incur the risk of rejecting potentially efficacious treatments. The endorsed recommendations inform the choice of trial-design appropriate for approval of psychopharmacological drugs. The recommendations strongly support the use of randomized clinical trials in general, and the use of placebo-controlled trials in particular., Competing Interests: Declaration of Competing Interest Guy M.

- Abstract
Objective: Discuss the experience of the New Jersey State Cancer Registry's (NJSCR's) transition to remote auditing of reporting facilities., Methods: We conducted remote audits from 2016-2019 for reporting years 2014-2017. Facilities were selected for audit if they (1) were <90% complete for the year; (2) had ≥10 electronic pathology records (HL7) without a corresponding hospital abstract; or (3) had not been audited in the past 5 years. HL7 records and disease index data were used to determine which cases were potentially unreported. Disease index data were linked to data from the NJSCR Surveillance, Epidemiology, and End Results Data Management System (SEER*DMS) via Match*Pro software. We describe the number of facilities audited and the number of unreported cases identified as a result of the audit process by reporting year and audit type. We also calculate the percent increase in cases reported by reporting year and describe salient challenges in the process., Results: During 4 years of data collection for the reporting years 2014-2017, 101 audits were completed and 10,546 cases were identified as unreported, representing a 7.1% increase in the number of reportable cases among those facilities audited. Challenges for the central registry involved organizing and reviewing large volumes of electronic data and Excel worksheets, and communications with facilities in the process of changing affiliations, personnel, or encryption policies., Conclusions: The new process has improved the audit experience for central registry staff and increased the capture of cases being reported to NJSCR. Facilities also made improvements to casefinding, reporting, and communications to the NJSCR.
