Orbital modulation of X-ray emission lines in Cygnus X-3

, 2009
We address the problem where the X-ray emission lines are formed and investigate orbital dynamics using Chandra HETG observations, photoionizing calculations and numerical wind-particle simulations.The observed Si XIV (6.185 A) and S XVI (4.733 A) line ...

KRAS and GNAS mutations in cell‐free DNA and in circulating epithelial cells in patients with intraductal papillary mucinous neoplasms—an observational pilot study

Molecular Oncology, EarlyView.
This study demonstrates that KRAS and GNAS mutations are more prevalent in patients with resected intraductal papillary mucinous neoplasms (IPMN) compared to those under clinical surveillance. GNAS mutations significantly differ between the two patient cohorts, indicating that their absence may serve as a potential biomarker to support conservative ...

Ultralow-threshold laser and blue shift cooperative luminescence in a Yb3+ doped silica microsphere

AIP Advances, 2014
An experimental investigation on ultralow threshold laser and blue shift cooperative luminescence (CL) in a Yb3+ doped silica microsphere (YDSM) with continuous-wave 976 nm laser diode pumping is reported.

Cross-linguistic similarity affects L2 cognate representation: blu vs. blue in Italian-English bilinguals [PDF]

, 2016
In a psycholinguistic study we explored semantic shifts of focal colours for ‘blue’ terms in Italian-English bilinguals. Italian speakers require more than one basic colour term to name blue colours: blu ‘dark blue’ and azzurro ‘light/medium blue ...

Integrative transcriptomic analysis identifies emetine as a promising candidate for overcoming acquired resistance to ALK inhibitors in lung cancer

Molecular Oncology, Volume 19, Issue 4, Page 1155-1169, April 2025.
We propose an efficient strategy to suppress ALK inhibitor (ALKi) resistance. By analyzing transcriptome data, we identified emetine as a potential inhibitor. We demonstrated that emetine exhibited effectiveness in inhibiting the growth of ALKi‐resistant cells, and further interpreted its impact on the resistant signatures through drug‐induced RNA ...

Near field spectral dispersion of dipole radiation: The maximum red and blue shifts, and the near and far field boundary

Results in Optics, 2021
Spectral dispersion of dipole radiation in near field zone is studied. Spectral changes are demonstrated using polychromatic incident light of Gaussian spectral profile as test examples. Both red and blue shifts are possible.

Gravity's universality: The physics underlying Tolman temperature gradients

, 2018
We provide a simple and clear verification of the physical need for temperature gradients in equilibrium states when gravitational fields are present. Our argument will be built in a completely kinematic manner, in terms of the gravitational red-shift ...

Genomic landscape and preclinical models of angiosarcoma

Molecular Oncology, Volume 19, Issue 4, Page 965-983, April 2025.
Angiosarcomas are a rare and aggressive cancer with a poor prognosis for patients. The genomic landscape of angiosarcoma can be highly complex and heterogenous; however, recent studies have identified some common features especially within anatomic and molecular subgroups.
