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.

Outflows in rho Ophiuchi as Seen with the Spitzer Infrared Array Camera

, 2009
Using the IRAC images from the Spitzer c2d program, we have made a survey of mid-infrared outflows in the rho Ophiuchi molecular cloud. Extended objects that have prominent emission in IRAC channel 2 (4.5 micron) compared to IRAC channel 1 (3.6 micron ...

A Cre‐dependent lentiviral vector for neuron subtype‐specific expression of large proteins

FEBS Letters, EarlyView.
We designed a versatile and modular lentivector comprising a Cre‐dependent switch and self‐cleaving 2A peptide and tested it for co‐expression of GFP and a 2.8 kb gene of interest (GOI) in mouse cortical parvalbumin (PV+) interneurons and midbrain dopamine (TH+) neurons.

High discrimination infrared polarimetry via intrinsic anisotropic photogating in black phosphorus meta-polarization detectors

Nature Communications
Filterless miniaturized polarization photodetectors are essential for next-generation ultracompact optical and optoelectronic systems. However, achieving high polarization discrimination and high sensitivity over a broad wavelength range based on a ...

Mid-infrared and optical spectroscopy of ultraluminous infrared galaxies: A comparison [PDF]

, 1999
New tools from Infrared Space Observatory (ISO) mid-infrared spectroscopy have recently become available to determine the power sources of dust-obscured ultraluminous infrared galaxies (ULIRGs).

Infrared Quantum Information [PDF]

Physical Review Letters, 2017
We discuss information-theoretic properties of low-energy photons and gravitons in the S-matrix. Given an incoming n-particle momentum eigenstate, we demonstrate that unobserved soft photons decohere nearly all outgoing momentum superpositions of charged particles, while the universality of gravity implies that soft gravitons decohere nearly all ...

The role of histone modifications in transcription regulation upon DNA damage

FEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

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 ...
