PURPOSE Persons with multiple chronic diseases must integrate self-management tasks for
potentially interacting conditions to attain desired clinical outcomes. Our goal was to identify …

We demonstrate, to our knowledge, the first bright circularly polarized high-harmonic beams
in the soft X-ray region of the electromagnetic spectrum, and use them to implement X-ray …

Background Interventions to improve care for persons with chronic medical conditions often
use quality of life (QOL) outcomes. These outcomes may be affected by coexisting (comorbid…

We generate angularly isolated beams of circularly polarized extreme ultraviolet light through
the first implementation of non-collinear high harmonic generation with circularly polarized …

High-harmonic generation driven by femtosecond lasers makes it possible to capture the
fastest dynamics in molecules and materials. However, thus far, the shortest isolated …

Optical interactions are governed by both spin and angular momentum conservation laws,
which serve as a tool for controlling light–matter interactions or elucidating electron dynamics …

PURPOSE Lower continuity of care has been associated with higher rates of adverse outcomes
for persons with multiple chronic medical conditions. It is unclear, however, whether this …

OBJECTIVE: To explore the constructs underlying a self-report assessment of multimorbidity.
STUDY DESIGN AND SETTING: We conducted a cross-sectional survey of 352 HMO …

Strong-field ionization provides fundamental insight into light-matter interactions, encoding
the structure of atoms and molecules on the subångström and subfemtosecond scales. In this …

Background: The Cancer Research Network (CRN) comprises the National Cancer Institute
and 11 nonprofit research centers affiliated with integrated health care delivery systems. The …
