Homogeneous Photometry for Star Clusters and Resolved Galaxies. II. Photometric Standard Stars
, 2000 Stars appearing in CCD images obtained over 224 nights during the course of 69 observing runs have been calibrated to the Johnson/Kron-Cousins BVRI photometric system defined by the equatorial standards of Landolt (1992, AJ, 104, 340).

Pediatric Blood &Cancer, EarlyView.ABSTRACT Purpose Pediatric central nervous system (CNS) tumors often recur despite multimodality therapy. Although re‐irradiation (re‐RT) has historically been limited by concerns for severe late toxicities, modern techniques have renewed interest in this approach. Proton therapy provides dosimetric advantages that may enable curative re‐treatment with

Laser frequency stabilization using a spatially multiplexed microfabricated Rb vapor cell
Applied Physics ExpressWe demonstrate a laser stabilization based on a spatially-multiplexed, microfabricated rubidium vapor cell. This design integrates multiple optical apertures within a cell, enabling a single input beam to simultaneously capture both Doppler-broadened and

Defining Roles in Pediatric Palliative Care: Perspectives From Oncology and Palliative Care Teams
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Early integration of pediatric palliative care (PPC) is associated with improved symptom management, quality of life, and healthcare utilization for children with cancer. Despite this, variation persists in how PPC is understood, operationalized, and integrated within pediatric oncology programs. In particular, ambiguity surrounding
