High-order replica bands in monolayer FeSe/SrTiO revealed by polarization-dependent photoemission spectroscopy.

The mechanism of the enhanced superconductivity in monolayer FeSe/SrTiO has been enthusiastically studied and debated over the past decade. One specific observation has been taken to be of central importance: the replica bands in the photoemission spectrum. Although suggestive of electron-phonon interaction in the material, the essence of these spectroscopic features remains highly controversial.

Noninvasive stereotactic radioablation for the treatment of atrial fibrillation: First-in-man experience.

Purpose: Catheter ablation is an effective therapy for atrial fibrillation (AF). However, risks remain, and improved efficacy is desired. Stereotactic body radiotherapy (SBRT) is a well-established therapy used to noninvasively treat malignancies and functional disorders with precision.

Safety and efficacy of stereotactic radioablation targeting pulmonary vein tissues in an experimental model.

Background: Stereotactic radioablation (SR), a commonly used therapy to treat malignant tumors, has been used to treat refractory ventricular tachycardia, but the feasibility of treating atrial fibrillation with SR is unknown.

Objective: We evaluated the safety and efficacy of SR targeting pulmonary vein (PV) antral tissues as a potential therapy for atrial fibrillation.

Methods: Seventeen adult canines and 2 adult swine underwent surgical fiducial marker placement, 3-dimensional anatomic rendering computed tomography angiogram of the left atrium, and creation of a treatment plan targeting the right superior PVs.

The Healthy for Life Taekwondo Pilot Study: A Preliminary Evaluation of Effects on Executive Function and BMI, Feasibility, and Acceptability.

There is growing consensus that exercise improves cognitive functioning, but research is needed to identify exercise interventions that optimize effects on cognition. The objective of this pilot study was to evaluate Taekwondo implemented in public middle school physical education (PE). Two classes were randomly assigned to either: five sessions per week of PE or three sessions of PE and two sessions of Taekwondo.
