Lived experiences of transgender and nonbinary people in the perioperative context: a qualitative study.

Background: Transgender and nonbinary (TNB) people experience obstacles that create barriers to accessing health care, including stigmatization and health inequities. Our intention was to describe the lived experiences of TNB patients and identify potential gaps in the education of health care professionals.

Methods: We conducted a qualitative descriptive study influenced by phenomenology by interviewing with TNB adults who underwent surgery in Canada within the previous 5 years.

Strong Solar Radiation Forces from Anomalously Reflecting Metasurfaces for Solar Sail Attitude Control.

We examine the theoretical implications of incorporating metasurfaces on solar sails, and the effect they can have on the forces applied to the sail. This would enable a significant enhancement over state-of-the- art attitude control by demonstrating a novel, propellant-free and low-mass approach to induce a roll torque on the sail, which is a current limitation in present state-of-the-art technology. We do so by utilizing anomalous optical reflections from the metasurfaces to generate a net in-plane lateral force, which can lead to a net torque along the roll axis of the sail, in addition to the other spatial movements exhibited by the sail from solar radiation pressure.
