LiYF4:Ho crystal in a magnetic field: high resolution optical spectroscopy

EPJ Web of Conferences, 2017
Low-temperature high-resolution optical spectra of LiYF4:Ho in an external magnetic field H are presented. A field-dependent transformation of the hyperfine structure of holmium spectral lines is studied for the cases H||c and H┴c.

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

Molecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

The Limits of Line Broadening: Modeling Stellar Spectra and Formation Temperatures at High Resolution

The Astrophysical Journal
The modeling of stellar spectra is pervasive in astronomy. Conventionally, the shapes of absorption lines are modeled by convolving thermal profiles (computed given some model stellar atmosphere and line list) with broadening kernels intended to account ...

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

The impact of interpolation in high-resolution spectroscopy

Astronomy & Astrophysics
Aims. We explore the impact that spectral interpolation introduces in radial velocity (RV) time-series that are extracted using templatebased methods, in particular systematic biases induced in this process. Methods.

PAK1 activation drives divergent resistance mechanisms to aromatase inhibition and tamoxifen in a luminal: A breast cancer model

Molecular Oncology, EarlyView.
Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

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

The 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
