Dissipative Processes and Their Role in the Evolution of Radio Galaxies [PDF]
Galaxies, 2019 Particle acceleration in relativistic jets, to very high levels of energy, occurs at the expense of the dissipation of magnetic or kinetic energy. Therefore, understanding the processes that can trigger this dissipation is key to the characterization of ...

Linking high-energy cosmic particles by black-hole jets embedded in large-scale structures [PDF]
, 2017 The origin of ultrahigh-energy cosmic rays (UHECRs) is a half-century-old enigma1. The mystery has been deepened by an intriguing coincidence: over ten orders of magnitude in energy, the energy generation rates of UHECRs, PeV neutrinos and isotropic sub ...

A relativistic mixing‐layer model for jets in low‐luminosity radio galaxies [PDF]
, 2009 We present an analytical model for jets in Fanaroff & Riley Class I (FR I) radio galaxies, in which an initially laminar, relativistic flow is surrounded by a shear layer.

Photopatternable PEDOT:PSS Hydrogels for High‐Resolution Photolithography
Advanced Science, EarlyView.A photosensitive biphasic conducting polymer hydrogel (PB‐CH) is rationally designed with PEDOT:PSS as the conductive phase and a light‐sensitive matrix as the mechanical phase. Such a PB‐CH offers a unique combination of excellent conductivity (≈30 S cm⁻¹), robust mechanical performance (with stretchability up to 50%), and high photopatternability ...

Ultra-high-energy cosmic rays from black hole jets of radio galaxies [PDF]
, 2008 The Auger Collaboration reports (Auger Collaboration 2007 Science 318 939, The Pierre Auger Collaboration 2008 Astropart. Phys. 29 188) that the arrival directions of ≳60 EeV ultra-high-energy cosmic rays (UHECRs) cluster along the supergalactic plane ...

Macromolecular Rapid Communications, EarlyView.Multidrug resistant Pseudomonas (P.) aeruginosa is detected in many infected wounds and is challenging to treat with antibiotics. As an alternative, this work incorporates anti‐P. aeruginosa Neko phages into electrospun fibres to explore their potential for treating infected wounds.

The X-ray jets of active galaxies [PDF]
, 2008 Jet physics is again flourishing as a result of Chandra’s ability to resolve high-energy emission from the radio-emitting structures of active galaxies and separate it from the X-ray-emitting thermal environments of the jets.

Similarity Assessment of the Engineering Concepts: Decision‐Making Support and Metrics
Systems Engineering, EarlyView.ABSTRACT The new product development (NPD) process is a systematic approach to bring new products and innovations to market. Nowadays, this process is affected by a number of influencing factors associated with the fast‐paced technological changes. One of those factors is the distributed design nature of product development activities: team members are

Relativistic jet feedback - II. Relationship to gigahertz peak spectrum and compact steep spectrum radio galaxies [PDF]
, 2018 We propose that Gigahertz Peak Spectrum (GPS) and Compact Steep Spectrum (CSS) radio sources are the signposts of relativistic jet feedback in evolving galaxies.

Science Triggers and Situational Interest in Everyday Family Life
Journal of Research in Science Teaching, EarlyView.ABSTRACT Interest in science is critical for science learning. The family plays a major role in supporting the development of children's interest in science by eliciting and fostering interest and engagement with science content and practice. This study characterizes triggers for interest in science in everyday family life and measures the duration of ...
