Patients with suspected or confirmed high-consequence infectious diseases (HCIDs) may present for care at any acute care facility. However, there are limited data to inform recommendations for the design, maintenance, and operation of isolation spaces for patients with suspected or confirmed HCIDs. To address this gap, we developed consensus statements by convening a group of 29 subject matter experts to participate in a modified Delphi process facilitated by a validated tool (the RAND-developed ExpertLens system).

We show that perylene-3,4,9,10-tetracarboxylate forms dynamic dimers in aqueous solution, with lifetimes long enough to allow intermolecular processes such as singlet fission. As these are transient dimers rather than stable aggregates, they retain a significant degree of disorder.

This study establishes a novel link between and the reactivity descriptors of conceptual density functional theory (c-DFT). Specifically, we derive expressions that relate the reaction force constant to nuclear softness and variations in chemical potential.

Nonetheless, most studies of habitat conversion focus on changes in species occurrences or abundances. We analyzed >14,000 behavioral observations across 55 bird species in communities in northwestern Costa Rica to determine how land use affects reproductive, foraging, and other passive kinds of behaviors not associated with either foraging or reproduction.
