BackgroundEmergency department based Physical Therapy (ED-PT) has been practiced globally in various forms for over 20 years and is an emerging resource in the US. While there is a growing body of evidence suggesting that ED-PT has a positive effect

Low back pain (LBP) leads to more than 4.3 million emergency department (ED) visits annually. Despite the number of ED visits for LBP, emergency medicine societies have not established clear guidelines for the evaluation and care of these patients. T

Augmented plasmonic damping of dipole-resonant gold (Au) nanoparticles (NP) physicochemically bonded onto edges of tungsten disulfide (WS2) nanosheets, ostensibly due to hot electron injection, is quantified using electron energy loss spectroscopy (E

Plasmonic nanocomposite materials have exhibited value for applications ranging from biological hyperthermia to optical sensing and waveguiding. Energy absorbed from incident irradiation can be re-emitted as light or decay into phonons that propagate

Electron probes can resolve bright and dark optical modes at subwavelength scales to distinguish localized effects, e.g., those of composition and geometry, via energy loss measurements. In this work, electron energy loss spectra of a metal nanospher
