The extreme Ultraviolet emission from the Sun between the Lyman-alpha lines of H I and C VI [PDF]

Symposium - International Astronomical Union, 1965
As a result of research carried out with rocket-borne grating spectrographs, the nature of the extreme ultraviolet spectrum of the Sun is now known to a short wavelength limit of 33.7 Å, the Lyman-alpha line of C VI. Most of the emission lines of wavelengths greater than 400 Å have been identified, as have those from 80 Å to 33.7 Å.

Extracellular vesicle lipidomics liquid biopsy reveals systemic and tumor microenvironment metabolic reprogramming in ovarian cancer

Molecular Oncology, EarlyView.
Extracellular vesicle (EV) lipidomic profiling of plasma and ascites from patients with high‐grade serous ovarian cancer and of ovarian cancer cell lines reveals enrichment of triglycerides (TGs), diacylglycerols (DGs), phosphatidylcholine (PCs), sphingomyelins (SMs), reflecting tumor metabolic reprogramming.

Search for emission-line galaxies towards nearby voids. List 2

, 1998
We present a second list of emission-line galaxies (ELGs) discovered during our survey of nearby voids. The project aims to answer the question of whether the giant galaxies are fair tracers of the large scale structure and whether the voids are really

The Magnitude of the Dark Ages 21 cm Signal in the Context of Existing Early and Late Time Constraints on ΛCDM

The Astrophysical Journal Letters
The dark ages 21 cm signal is a promising probe of the currently unobserved infant Universe between the formation of the cosmic microwave background around z  ≈ 1100 and the first galaxies around z  ≈ 30.

Improving accretion diagnostics for young stellar objects with mid-infrared hydrogen lines from JWST/MIRI

Astronomy & Astrophysics
Context. We present a comprehensive study of mid-infrared neutral hydrogen (H i) emission lines in 79 nearby (d < 200 pc) young stars using the James Webb Space Telescope (JWST) Mid-Infrared Instrument (MIRI).

Regulation of the lncRNA NEAT1 by p53‐ΔNp63 crosstalk modulates the DNA damage response and therapeutic efficacy in HNSCC

Molecular Oncology, EarlyView.
In head and neck squamous cell carcinoma (HNSCC) p53 and p63 exert opposite roles on the transcription regulation of the lncRNA NEAT1. Under basal conditions, p53 levels are low and p63 represses NEAT1 expression. Upon genotoxic stress, p53 is rapidly induced, displacing p63 from the NEAT1 promoter leading to NEAT1 transcriptional activation and ...

Looking at the Distant Universe with the MeerKAT Array: The H i Mass Function in the Local Universe

The Astrophysical Journal
We present measurements of the neutral atomic hydrogen (H i ) mass function (H i MF) and cosmic H i density (Ω _H I ) at 0 ≤ z ≤ 0.088 from the Looking at the Distant Universe with MeerKAT Array (LADUMA) survey.

A Semiblind PCA-based Foreground Subtraction Method for 21 cm Intensity Mapping

The Astrophysical Journal, 2023
The principal component analysis (PCA) method and the singular value decomposition (SVD) method are widely used for foreground subtraction in 21 cm intensity mapping experiments.
