High-Resolution Vacuum Ultraviolet Photoelectron Spectroscopy

open access: yesCHIMIA, 2001
The development of narrow bandwidth tunable laser systems in the vacuum ultraviolet region of the electromagnetic spectrum and of new experimental methods has recently enabled a significant improvement in the resolution that can be achieved by ...

κ Andromedae b Is a Fast Rotator from KPIC High-resolution Spectroscopy

open access: yesThe Astronomical Journal
We used the Keck Planet Imager and Characterizer to obtain high-resolution ( R ∼ 35,000) K -band spectra of κ Andromedae b, a planetary-mass companion orbiting the B9V star, κ Andromedae A. We characterized its spin, radial velocity, and bulk atmospheric

High resolution optical spectroscopy of IRAS 09425-6040 (=GLMP 260)

open access: yes, 2006
We present high resolution optical spectroscopic observations of IRAS 09425-6040, a peculiar, extremely red, C-rich AGB star showing prominent O-rich dust features in its ISO infrared spectrum attributed to crystalline silicates.

Dual targeting of RET and SRC synergizes in RET fusion‐positive cancer cells

open access: yesMolecular Oncology, EarlyView.
Despite the strong activity of selective RET tyrosine kinase inhibitors (TKIs), resistance of RET fusion‐positive (RET+) lung cancer and thyroid cancer frequently occurs and is mainly driven by RET‐independent bypass mechanisms. Son et al. show that SRC TKIs significantly inhibit PAK and AKT survival signaling and enhance the efficacy of RET TKIs in ...

PDS 70b Shows Stellar-like Carbon-to-oxygen Ratio

open access: yesThe Astrophysical Journal Letters
The ~5 Myr PDS 70 is the only known system with protoplanets residing in the cavity of the circumstellar disk from which they formed, ideal for studying exoplanet formation and evolution within its natal environment.

High resolution spectroscopy in the microwave and far infrared [PDF]

open access: yes, 1990
High resolution rotational spectroscopy has long been central to remote sensing techniques in atmospheric sciences and astronomy. As such, laboratory measurements must supply the required data to make direct interpretation of data for instruments which ...

Strength through diversity: how cancers thrive when clones cooperate

open access: yesMolecular Oncology, EarlyView.
Intratumor heterogeneity can offer direct benefits to the tumor through cooperation between different clones. In this review, Kuiken et al. discuss existing evidence for clonal cooperativity to identify overarching principles, and highlight how novel technological developments could address remaining open questions.
