A radio-jet-galaxy interaction in 3C 441 [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 Multi-wavelength imaging and spectroscopy of the z=0.708 radio galaxy 3C441 and a red aligned optical/infrared component are used to show that the most striking aspect of the radio-optical ``alignment effect'' in this object is due to the interaction of the radio jet with a companion galaxy in the same group or cluster.

POWERFUL RELATIVISTIC JETS IN SPIRAL GALAXIES [PDF]
International Journal of Modern Physics: Conference Series, 2012 The discovery of high-energy (E > 100 MeV) γ rays from Narrow-Line Seyfert 1 Galaxies (γ-NLS1s) has confirmed the presence of powerful relativistic jets in this class of active galactic nuclei (AGN). Although the jet emission is similar to that of blazars and radio galaxies, γ-NLS1s have some striking differences: relatively small masses (106-8 M⊙),

Substituent‐Based Modulation of Self‐Assembly and Immunogenicity of Amphipathic Peptides
Advanced Science, EarlyView.This study systematically investigates how positional and subtle changes, such as substituents on the phenyl ring attached to short amphipathic peptides, influence their self‐assembly, fibril morphology, and immunogenic responses. ABSTRACT Self‐assembled peptide‐based biomaterials provide versatile platforms for biomedical uses, featuring customizable ...

Prioritized Real‐Time UAV‐Based Vessel Detection for Efficient Maritime Search
Journal of Field Robotics, EarlyView.ABSTRACT Real‐time vessel detection in maritime environments is crucial for diverse applications requiring speed and accuracy. Static camera views often introduce blind spots, compromising detection efficiency. This paper proposes a novel, real‐time UAV‐based system that uses a dynamic camera control strategy to address this limitation.

The Jet-Cloud Interaction in 3CR Galaxies: Preliminary Results in Four Galaxies [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractWe present preliminary results of the Gemini/GMOS longslit spectra for four radiogalaxies: 3C 135, 3C 180, 3C 234 and 3C 284. These objects are a subsample of a set of galaxies with noticeable extended structure selected from the HST/WFPC2 3CR Snapshot Survey, data taken with the filters F555W, F702W and narrow-ramp.
