On Black Hole Masses and Radio Loudness in AGN
, 2000 The distribution of radio to optical fluxes in AGN is bimodal. The physical origin for this bimodality is not understood. In this Letter I describe observational evidence, based on the Boroson & Green PG quasar sample, that the radio loudness bimodality ...

Suppressed radio emission in supercluster galaxies: enhanced ram pressure in merging clusters? [PDF]
, 2007 The environmental influence on the 1.4 GHz continuum radio emission of galaxies is analyzed in a 600 deg2 region of the local Universe containing the Shapley Supercluster (SSC).

Mental imagery for musical changes in loudness
Frontiers in Psychology, 2012 Musicians imagine music during mental rehearsal, when reading from a score, and while composing. An important characteristic of music is its temporality.

A Unified Theory of Psychophysical Laws in Auditory Intensity Perception
Frontiers in Psychology, 2020 Psychophysical laws quantitatively relate perceptual magnitude to stimulus intensity. While most people have accepted Stevens’s power function as the psychophysical law, few believe in Fechner’s original idea using just-noticeable-differences (jnd) as a ...

Merging the Psychophysical Function With Response Times for Auditory Detection of One vs. Two Tones
Frontiers in Psychology, 2022 The purpose of this study is to take preliminary steps to unify psychoacoustic techniques with reaction-time methodologies to address the perceptual mechanisms responsible for the detection of one vs. multiple sounds.

Somatosensory tinnitus: current evidence and future perspectives [PDF]
, 2017 In some individuals, tinnitus can be modulated by specific maneuvers of the temporomandibular joint, head and neck, eyes, and limbs. Neuroplasticity seems to play a central role in this capacity for modulation, suggesting that abnormal interactions ...

Peptide Sequencing With Single Acid Resolution Using a Sub‐Nanometer Diameter Pore
Advanced Functional Materials, EarlyView.To sequence a single molecule of Aβ1−42–sodium dodecyl sulfate (SDS), the aggregate is forced through a sub‐nanopore 0.4 nm in diameter spanning a 4.0 nm thick membrane. The figure is a visual molecular dynamics (VMD) snapshot depicting the translocation of Aβ1−42–SDS through the pore; only the peptide, the SDS, the Na+ (yellow/green) and Cl− (cyan ...

Loudness (annoyance), prediction procedure for steady sounds [PDF]
, 1972 Method has been devised to predict loudness level of any steady sound solely from its measured power spectrum level. Method is based on assumption that, with respect to loudness sensation, the human auditory system acts as open-loop transmission system ...
