A model-based analysis of sound transmission in a deep ice-covered Arctic ocean recorded during the Ice Experiment 2014 is presented. A source of opportunity transmitted mid-frequency (3500 Hz) 5 s duration continuous wave pulses. The source and rece

Vaccine boosters and infection can facilitate the development of SARS-CoV-2 antibodies with improved potency and breadth. Here, we observed super-immunity in a camelid extensively immunized with the SARS-CoV-2 receptor-binding domain (RBD). We rapidl

Two experiments on midfrequency acoustic transmission under ice in the Beaufort Sea are discussed. The APL-ICEX14 measurements were made using 3500 Hz 5s-long CW pulses for fixed geometry of source and receiver at ∼30 m depths and ∼720 m range. T

This paper is concerned with the development of a system for the discrimination of military munitions and unexploded ordnance (UXO) in shallow underwater environments. Acoustic color features corresponding to calibrated target strength as a function

Some users have been hesitant to take on the validation of alternative methods. However, recombinant factor C (rFC) tests are so highly analogous to the horseshoe crab-sourced Limulus amebocyte lysate (LAL) tests that users should consider their adva

A new, fully automated approach for obtaining an object's acoustic-color template –uncontaminated by background seafloor – from low-frequency sonar data is proposed. The developed family of algorithms eliminates several time-consuming tasks that

Mid-frequency (3.5 kHz) pulses (5 pings, 5s-long, one per minute) were radiated by an omnidirectional source of opportunity in a deep (3km) Arctic ocean at 30m depth under ice during the ICEX14 experiment, ALAS component. Data analysis and modeling r

The Target and Reverberation EXperiment 2013 (TREX13) included a comprehensive reverberation field project in the frequency band of 2–10 kHz, and was carried out off the coast of Panama City, FL, USA, from April 21 to May 17, 2013. A spatially fixe

Low frequency sonar has the capability of penetrating sediment and imaging buried objects, making it a candidate technology for the detection and classification of buried unexploded ordnance (UXO). To improve detection and classification, systems oft
