The measurement of ionospheric absorption using extraterrestrial radio waves [PDF]
, 1957 Introduction: The discovery by Jansky in 1932 of the presence of radio waves incident upon the earth from outer space has led to several new methods of studying the earth's upper atmosphere.

Galaxy Morphology - Halo Gas Connections
, 2005 We studied a sample of 38 intermediate redshift MgII absorption-selected galaxies using (1) Keck/HIRES and VLT/UVES quasar spectra to measure the halo gas kinematics from MgII absorption profiles and (2) HST/WFPC-2 images to study the absorbing galaxy ...

FEBS Open Bio, EarlyView.Osimertinib reduces angiogenesis and PDL1 expression in in ovo tumors, transforming them into ‘cold tumors’ with lower immune activity. Anatomopathological and transcriptomic analyses highlight its therapeutic impact on tumor biology. This study underscores osimertinib's potential to reshape the tumor microenvironment and provides insights into its ...

The convolution theorem for nonlinear optics
, 2007 We have expressed the nonlinear optical absorption of a semiconductor in terms of its linear spectrum. We determined that the two-photon absorption coefficient in a strong DC-electric field of a direct gap semiconductor can be expressed as the product of

A potential tumor suppressor role of PLK2 in glioblastoma
FEBS Open Bio, EarlyView.PLK2 was consistently downregulated in GBM tissues. Overexpression of PLK2 in GBM cell lines U87MG and U251 reduced their tumorigenic potential and enhanced cell cycle arrest and apoptosis. Suggesting that PLK2 overexpression could potentially be leveraged as a therapeutic strategy to inhibit tumor progression and enhance apoptosis, providing new ...

Architected Lattices with a Topological Transition
Advanced Engineering Materials, EarlyView., 2023 This article develops topological metamaterials showing multidirectional two‐step deformation under compression by embedding contact‐enabled topological mechanisms into lattice structures. Experiments on 3D‐printed 2D and 3D lattices and finite element simulations are conducted to demonstrate the working principle of the topological metamaterials.

Identification of inhibitors of the Salmonella FraB deglycase, a drug target
FEBS Open Bio, EarlyView.A high‐throughput screen was used to identify inhibitors of Salmonella FraB, a drug target. Characterization of top hits (identified after an additional counter screen) revealed that some triazolidines, thiadiazolidines, and triazolothiadiazoles are mixed‐type inhibitors of FraB.

Sensitivity of p-mode absorption on magnetic region properties and kernel functions
, 2011 Aims. Magnetohydrodynamic (MHD) sausage tube waves are excited in magnetic flux tubes by p-mode forcing. These tube waves carry energy away from the p-mode cavity which results in a source of absorption.
