Bulk Condensation by an Active Interface.

We present experiments, supported by mechanically detailed simulations, establishing bulk condensation of a hard-bead fluid by a tiny population of orientable motile grains that self-assembles into a moving polarized monolayer. In a quasi-1D geometry two such layers, oppositely aligned, immobilize the condensed nonmotile component. We account for our observations through a continuum theory with a naturally nonreciprocal Cahn-Hilliard structure, whose predicted trends as a function of packing fraction are consistent with our observations.

Patient Preferences for Direct-to-Consumer Telemedicine Services: Replication and Extension of a Nationwide Survey.

Background: A 2017 survey of patient perspectives showed overall willingness and comfort to use telemedicine, but low actual use. Given recent growth and widespread exposure of patients to telemedicine, patient preferences are likely to have changed.

Objective: This study aimed to (1) identify demographic trends in patient preferences and experiences; (2) measure ease of use and satisfaction of telemedicine; and (3) measure changes in telemedicine use, willingness, and comfort since 2017.

Sublingual Administration of Tacrolimus is Safe and Provides Similar Drug Exposure to Per-oral Route in Liver Transplant Recipients During Early Postoperative Period-A Large, Retrospective, Observational Study.

Background/aims: Per-oral (PO) administration of tacrolimus (TAC) results in inadequate trough levels in the early postoperative period in liver-transplant (LT) recipients who undergo Roux-en-Y hepaticojejunostomy for biliary reconstruction. Sublingual administration (SL) of tacrolimus provides an alternative route in such patients.The objectives of this study were to assess the feasibility and safety of SL tacrolimus in adult LT-recipients in the early postoperative period and to compare therapeutic efficacy of SL administration of tacrolimus versus PO route.
