Extended search for the invisible axion with the axion dark matter experiment

This Letter reports on a cavity haloscope search for dark matter axions in the Galactic halo in the mass range 2.81–3.31μeV. This search utilizes the combination of a low-noise Josephson parametric amplifier and a large-cavity haloscope to achieve unprecedented sensitivity across this mass range. This search excludes the full range of axion-photon coupling values predicted in benchmark models of the invisible axion that solve the strong CP problem of quantum chromodynamics

Search for invisible axion dark matter with the Axion Dark Matter Experiment

This Letter reports the results from a haloscope search for dark matter axions with masses between 2.66 and 2.81μeV. The search excludes the range of axion-photon couplings predicted by plausible models of the invisible axion. This unprecedented sensitivity is achieved by operating a large-volume haloscope at subkelvin temperatures, thereby reducing thermal noise as well as the excess noise from the ultralow-noise superconducting quantum interference device amplifier used for the signal power readout. Ongoing searches will provide nearly definitive tests of the invisible axion model over a wide range of axion masses

Remote telesurgical mentoring: feasibility and efficacy

Abstract We report our experience in performing telesurgically-mentored procedures from Baltimore, MD to Thailand, Austria, Italy and Singapore. We additionally report on a case of remote robotic manipulation using a robot designed for Percutaneous Access of the Kidney (PAKY). Telementoring was performed using a video teleconferencing platform including audio, video, real-time video telestration and remote control of the AESOP robotic arm that manipulates the laparoscopic camera. The international telementoring was achieved over 3- ISDN lines (384 Kilobytes/sec). The robotic arm and PAKY robot were controlled over a separate analog POTS line. Telecommunications links were successfully established to these remote locations that ranged in distance from approximately 4,500-11,000 miles. There was no perceptible impact of time delay on the surgical procedures. All procedures were successfully completed without additional complications. Multiple laparoscopic surgeries to include varicocelectomy (4), nephrectomy (4), adrenalectomy (1) and cholecystectomies (2) were demonstrated. Remote robotic percutaneous access to the kidney was successfully conducted within fifteen minutes from Baltimore, Maryland to Rome, Italy

Variation in high-priority drug-drug interaction alerts across institutions and electronic health records

Objective: The United States Office of the National Coordinator for Health Information Technology sponsored the development of a “high-priority” list of drug-drug interactions (DDIs) to be used for clinical decision support. We assessed current adoption of this list and current alerting practice for these DDIs with regard to alert implementation (presence or absence of an alert) and display (alert appearance as interruptive or passive). Materials and methods: We conducted evaluations of electronic health records (EHRs) at a convenience sample of health care organizations across the United States using a standardized testing protocol with simulated orders. Results: Evaluations of 19 systems were conducted at 13 sites using 14 different EHRs. Across systems, 69% of the high-priority DDI pairs produced alerts. Implementation and display of the DDI alerts tested varied between systems, even when the same EHR vendor was used. Across the drug pairs evaluated, implementation and display of DDI alerts differed, ranging from 27% (4/15) to 93% (14/15) implementation. Discussion: Currently, there is no standard of care covering which DDI alerts to implement or how to display them to providers. Opportunities to improve DDI alerting include using differential displays based on DDI severity, establishing improved lists of clinically significant DDIs, and thoroughly reviewing organizational implementation decisions regarding DDIs. Conclusion: DDI alerting is clinically important but not standardized. There is significant room for improvement and standardization around evidence-based DDIs
