Autor: Jordan W. Bishop, Philip S. Blom, Jeremy Webster, Will Reichard-Flynn, Youzuo Lin

Publikováno v: The Journal of the Acoustical Society of America. 152:2434-2445

We develop a deep learning-based infrasonic detection and categorization methodology that uses convolutional neural networks with self-attention layers to identify stationary and non-stationary signals in infrasound array processing results. Using fe

Effects of Resonant Electromagnetic Fields on Biofilm Formation in Pseudomonas aeruginosa

Autor: Janus A. J. Haagensen, Michael Bache, Livio Giuliani, Nikolaj S. Blom

Publikováno v: Applied Sciences, Vol 11, Iss 16, p 7760 (2021)

The global rise of antimicrobial resistance (AMR) constitutes a future health threat and dictates a need to explore alternative and non-chemical approaches. The aim of this study was to explore the use of weak resonant electromagnetic fields as a met

The 15 January 2022 climactic eruption of Hunga volcano, Tonga, produced an explosion in the atmosphere of a size that has not been documented in the modern geophysical record. The event generated a broad range of atmospheric waves observed globally

Estimating Effectiveness of Identifying Human Trafficking via Data Envelopment Analysis

Autor: Geri L. Dimas, Malak El Khalkhali, Alex Bender, Kayse Lee Maass, Renata A. Konrad, Jeffrey S. Blom, Joe Zhu, Andrew C. Trapp

Publikováno v: INFORMS Journal on Applied Analytics.

Transit monitoring is a preventive approach used to identify possible cases of human trafficking before exploitation while an individual is in transit or before crossing a border. Transit monitoring is often conducted by nongovernmental organizations

Evaluating the location capabilities of a regional infrasonic network in Utah, US, using both ray tracing-derived and empirical-derived celerity-range and backazimuth models

Autor: Fransiska K Dannemann Dugick, Philip S Blom, Brian W Stump, Chris T Hayward, Stephen J Arrowsmith, Joshua C Carmichael, Omar E Marcillo

Publikováno v: Geophysical Journal International. 229:2133-2146

SUMMARY More realistic models for infrasound signal propagation across a region can be used to improve the precision and accuracy of spatial and temporal source localization estimates. Motivated by incomplete infrasound event bulletins in the Western

Publikováno v: Bulletin of the Seismological Society of America. 112:553-574

We report on the source of seismoacoustic pulses that were observed across the state of Oklahoma (OK) during summer of 2019, and the subject of national media coverage and speculation. Seismic network data collected across four U.S. states and interv

Predicted coronavirus Nsp5 protease cleavage sites in the human proteome

Autor: Benjamin M. Scott, Vincent Lacasse, Ditte G. Blom, Peter D. Tonner, Nikolaj S. Blom

Publikováno v: Scott, B M, Lacasse, V, Blom, D G, Tonner, P D & Blom, N S 2022, ' Predicted coronavirus Nsp5 protease cleavage sites in the human proteome ', BMC Genomic Data, vol. 23, no. 1, 25 . https://doi.org/10.1186/s12863-022-01044-y

Background The coronavirus nonstructural protein 5 (Nsp5) is a cysteine protease required for processing the viral polyprotein and is therefore crucial for viral replication. Nsp5 from several coronaviruses have also been found to cleave host protein

Infrasound Propagation with Realistic Terrain and Atmospheres Using a Three-Dimensional Finite-Difference Time-Domain Method

Autor: Jordan W. Bishop, Philip S. Blom, David Fee

Infrasound observations and complimentary numerical simulations have shown that infrasound propagation is strongly influenced by topography within approximately 10 km from the source. Recent computational efforts using ray theory have shown that topo

Regional and global scale propagation simulations of infrasonic signals

Autor: Philip S. Blom

Publikováno v: The Journal of the Acoustical Society of America. 153:A218-A218

Infrasonic signals are frequently observed at large propagation distances of 100s to 1000s of kilometers from the source and, in extreme cases, signals have been observed to circle the globe. Simulating acoustic propagation at these large scales requ
