UNIFIED SCHEMES FOR RADIO-LOUD ACTIVE GALACTIC NUCLEI [PDF]
, 1995 The appearance of active galactic nuclei (AGN) depends so strongly on orientation that our current classification schemes are dominated by random pointing directions instead of more interesting physical properties.

Versatile Gasochromic Hydrogen Detection via Supraparticle‐Based Applied Composite Materials
Advanced Optical Materials, EarlyView.Silica‐platinum‐resazurin supraparticles are embedded into PMMA to form suprabeads and thin films. The thereby obtained indicators change color from purple to pink to colorless on hydrogen exposure. The indicator systems are tested under various environmental conditions, and their performance is related to their microscopically visualized structure ...

Observational Tests of Active Galactic Nuclei Feedback: An Overview of Approaches and Interpretation [PDF]
GalaxiesGrowing supermassive black holes (Active Galactic Nuclei; AGN) release energy with the potential to alter their host galaxies and larger-scale environment; a process named “AGN feedback”.

BLACK HOLE VARIABILITY AND THE STAR FORMATION–ACTIVE GALACTIC NUCLEUS CONNECTION: DO ALL STAR-FORMING GALAXIES HOST AN ACTIVE GALACTIC NUCLEUS? [PDF]
, 2013 We investigate the effect of active galactic nucleus (AGN) variability on the observed connection between star formation and black hole accretion in extragalactic surveys.

Advanced Robotics Research, EarlyView.This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.

DO QUIESCENT AND ACTIVE GALAXIES HAVE DIFFERENT MBH–σ* RELATIONS? [PDF]
, 2013 To investigate the validity of the assumption that quiescent galaxies and active galaxies follow the same black hole mass (MBH)–stellar velocity dispersion (σ*) relation, as required for the calibration of MBH estimators for broad line active galactic ...

Advanced Science, EarlyView.In macrophage‐myofibroblast transition, upregulated NNMT depletes S‐Adenosylmethionine (SAM) and nicotinamide adenine dinucleotide(NAD+), thereby triggering epigenetic reprogramming via Histone H3 Lysine 27 acetylation (H3K27ac) accumulation at the promoter region of master transcription factor Prrx1.

A semi-analytic model for the co-evolution of galaxies, black holes and active galactic nuclei [PDF]
, 2008 We present a new semi-analytic model that self-consistently traces the growth of supermassive black holes (BH) and their host galaxies within the context of the Lambda cold dark matter ( CDM) cosmological framework.

A New Sample of (Wandering) Massive Black Holes in Dwarf Galaxies from High-resolution Radio Observations [PDF]
Astrophysical Journal, 2019 We present a sample of nearby dwarf galaxies with radio-selected accreting massive black holes (BHs), the majority of which are non-nuclear. We observed 111 galaxies using sensitive, high-resolution observations from the Karl G.
