Lyomyces denudatus, a new species with a disjunct distribution [PDF]
, 2022 We describe a new corticioid species Lyomyces denudatus based on morphological and molecular data (nuc rDNA ITS). It occurs both in the extreme south of South America and New Zealand. Our phylogenetic analyses place it near L.

Binaural rendering from microphone array signals of arbitrary geometry [PDF]
, 2021 A method of binaural rendering from microphone array signals of arbitrary geometry is proposed. To reproduce binaural signals from microphone array recordings at a remote location, a spherical microphone array is generally used for capturing a soundfield.

Miniature photonic-crystal hydrophone optimized for ocean acoustics [PDF]
Journal of Acoustical Society of America (March 2011), 2010 This work reports on an optical hydrophone that is insensitive to hydrostatic pressure, yet capable of measuring acoustic pressures as low as the background noise in the ocean in a frequency range of 1 Hz to 100 kHz. The miniature hydrophone consists of a Fabry-Perot interferometer made of a photonic-crystal reflector interrogated with a single-mode ...

Ionospheric response to the 2009 sudden stratospheric warming over the equatorial, low, and middle latitudes in the South American sector [PDF]
, 2015 The present study investigates the ionospheric total electron content (TEC) and F-layer response in the Southern Hemisphere equatorial, low, and middle latitudes due to major sudden stratospheric warming (SSW) event, which took place during January ...

Acoustic contributions of a sound absorbing blanket placed in a double panel structure: Absorption Versus Transmission [PDF]
The Journal of the Acoustical Society of America 128, 2 (2010) 8, 2010 The objective of this paper is to propose a simple tool to estimate the absorption vs. transmission loss contributions of a multilayered blanket unbounded in a double panel structure and thus guide its optimization. The normal incidence airborne sound transmission loss of the double panel structure, without structure-borne connections, is written in ...

JUE Insight: The (Non-)Effect of Opportunity Zones on Housing Prices [PDF]
, 2022 Will the Opportunity Zones (OZ) program, America's largest new place-based policy in decades, generate neighborhood change? We compare single-family housing price growth in OZs with price growth in areas that were eligible but not included in the program. We also compare OZs to their nearest geographic neighbors.

A study of the secondary cosmic $γ$ -ray flux in India during the Great American solar eclipse on 21$^{st}$ August 2017 [PDF]
, 2019 We present the results from the measurement of secondary cosmic gamma-ray flux using a NaI(Tl) scintillator detector during a total solar eclipse. The unique feature of this experiment is that it was carried out at a place where the solar eclipse was not observable. The total solar eclipse of August 21, 2017, was visible in most of the regions of North

Experimental comparison of autodyne and heterodyne laser interferometry using a Nd:YVO4 microchip laser [PDF]
Journal of the Optical Society of America A 28, 8 (2011) 1741-1746, 2012 Using a Nd:YVO4 microchip laser with a relaxation frequency in the megahertz range, we have experimentally compared a heterodyne interferometer based on a Michelson configuration with an autodyne interferometer based on the laser optical feedback imaging (LOFI) method regarding their signal to noise ratios.

Comparative study of autodyne and heterodyne laser interferometry for imaging [PDF]
Journal of the Optical Society of America A 27 (2010) 2450, 2014 For given laser output power, object under investigation and photodiode noise level, we have theoretically compared the signal to noise ratio (SNR) of a heterodyne scanning imager based on a Michelson interferometer and of an autodyne setup based on the Laser Optical Feedback Imaging (LOFI) technique. In both cases, the image is obtained point by point.
