Reverberation Mapping of the Narrow-line Seyfert 1 Galaxy I Zwicky 1: Black Hole Mass [PDF]
Astrophysical Journal, 2019 We report results of the first reverberation mapping campaign of I Zwicky 1 during 2014–2016, which showed unambiguous reverberations of the broad Hβ line emission in the varying optical continuum.

Augmenting Environmental Interaction in Audio Feedback Systems
Applied Sciences, 2016 Audio feedback is defined as a positive feedback of acoustic signals where an audio input and output form a loop, and may be utilized artistically. This article presents new context-based controls over audio feedback, leading to the generation of desired

, 1999 The masses and emission-line region sizes of Active Galactic Nuclei (AGNs) can be measured by ``reverberation-mapping'' (measuring the lag of the emission-line luminosity after changes in the continuum). We use tis technique to calibrate similar size and

Spring Reverberation: A Physical Perspective [PDF]
, 2009 Spring-based artificial reverberation was one of the earliest attempts at compact replication of room-like reverberation for studio use. The popularity and unique sound of this effect have given it a status and desirability apart from its original use ...

FEBS Open Bio, EarlyView.Chemotherapies such as doxorubicin can have toxic effects on healthy cardiovascular/heart tissue. Following up on a doxorubicin toxicity study in mice without tumors where nitrate water was cardioprotective (lessened toxicity), this study with tumor‐bearing mice undergoing doxorubicin treatment showed no negative effect of nitrate and nitrite on drug ...

New Directions for Adult and Continuing Education, EarlyView.ABSTRACT This article explores how artificial intelligence (AI) can support online adult learning by aligning with Knowles’ four principles of andragogy: involvement, experience, problem‐centeredness, and relevance. Three activities were analyzed using a comparative case study (CCS) method.
