The Astrophysical JournalRadiation pressure is a key mechanism by which stellar feedback disrupts molecular clouds and drives H ii region expansion. This includes direct radiation pressure exerted by UV photons on dust grains, pressure associated with photoionization, and ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Outcomes in relapsed or refractory pediatric and AYA bone sarcomas remain poor, and the impact of early referral to specialized sarcoma centers on survival is unclear. Early centralization of care may improve local and systemic treatment quality, but evidence in this population is limited.

Thermodynamics of the H ii Region Sh2-158 and “Direct” Measurement of Its Turbulence
The Astrophysical JournalThree SITELLE hyperspectral cubes were used to obtain 12 million spectra sampling 11 emission lines of the H ii region Sh2-158. This data set enables the calculation of numerous diagnostics and physical parameters such as abundance, electronic density ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT The medical burdens of sickle cell disease (SCD) and transfusion‐dependent β‐thalassemia (TDT) are chronic and cumulative, even in children. Yet the effects expand beyond medications and healthcare visits due to their impacts on school attendance, academic performance, and peer engagement.

The Detection of Higher-order Millimeter Hydrogen Recombination Lines in the Large Magellanic Cloud
The Astrophysical Journal, 2023 We report the first extragalactic detection of the higher-order millimeter hydrogen recombination lines (Δ n > 2). The γ -, ϵ -, and η -transitions have been detected toward the millimeter continuum source N 105–1 A in the star-forming region N 105 in ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...

Resonant Scattering of the He i 1.0833 μm Triplet in H ii Regions: Emission Spectra
The Astrophysical JournalResonant scattering of He i 1.0833 μ m triplet photons by metastable He 2 ^3 S _1 is studied for optical depths characteristic of H ii regions. Regions with large He 2 ^3 S _1 column densities are predicted to have unusually broad multipeaked 1.0833 μ m ...

New Infrared Sources Associated with H II Regions [PDF]
Symposium - International Astronomical Union, 1973 Photometry and mapping in the wavelength range 1.65–20 μ of the H II regions W3 and NGC 7538 have led to the discovery of a dozen new infrared emission sources. The sources have flux densities ranging up to 10–23 Wm–2 Hz–1 at 20 μ and diameters from < 3 to 40″.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...
