A Review of Methods for Ship Detection with Electro-Optical Images in Marine Environments

Journal of Marine Science and Engineering, 2021
The ocean connects all continents and is an important space for human activities. Ship detection with electro-optical images has shown great potential due to the abundant imaging spectrum and, hence, strongly supports human activities in the ocean.

Polycyclic Aromatic Hydrocarbon Emission within Lyα Blobs [PDF]

, 2011
We present Spitzer observations of Lyα blobs (LABs) at z = 2.38-3.09. The mid-infrared ratios (4.5 μm/8 μm and 8 μm/24 μm) indicate that ~60% of LAB infrared counterparts are cool, consistent with their infrared output being dominated by star formation ...

Near-Infrared Spectra of Ultraluminous Infrared Galaxies [PDF]

The Astrophysical Journal, 1999
Near infrared spectra with resolution R ~ 1100 in the rest wavelength range 1.8-2.2 microns have been obtained for a complete sample of 33 ultraluminous infrared galaxies. Of the 33 objects observed, 2 show evidence of a central AGN through either a broad Paschen-alpha line or emission in the 1.963 micron fine structure of [Si VI].

Neutral Gas Outflows and Inflows in Infrared-Faint Seyfert Galaxies

, 2009
Previous studies of the Na I D interstellar absorption line doublet have shown that galactic winds occur in most galaxies with high infrared luminosities.

ON INFRARED DIVERGENCES

Nuclear Physics B, 1979
Revised 25 September 1978 We study the structure of infrared divergences in superrenormalizable interactions. We conjecture that there is an extension of the Bogoliubov-Parasiuk-Hepp theorem which copes also with infrared divergences. We discuss the consequences of this conjecture on the singularities of the Borel transform in a massless asymptotic ...

Molecular imaging predicts trastuzumab‐deruxtecan (T‐DXd) response in head and neck cancer xenograft models

Molecular Oncology, EarlyView.
Trastuzumab‐deruxtecan, a HER2‐targeting antibody‐drug conjugate, shows promising antitumor activity in head and neck squamous cell carcinoma with low HER2 expression. In vitro and in vivo studies demonstrated dose‐dependent cell death and tumor growth reduction in low HER2‐expressing cell lines, which correlated with drug accumulation measured using a

Transient Study of Femtosecond Laser–Induced Ge₂Sb₂Te₅ Phase Change Film Morphology

Micromachines, 2021
Femtosecond laser-induced crystallization and ablation of Ge2Sb2Te5 (GST) phase change film is investigated by reflectivity pump-probing technology. Below the ablation threshold, the face-centered cubic structure (FCC) state in the central area can be ...
