eDNA Is a Useful Environmental Monitoring Tool for Assessing Stream Ecological Health

open access: yesEnvironmental DNA, Volume 6, Issue 4, July–August 2024.
Ecosystem health assessments made by traditional biomonitoring techniques were compared to those made using eDNA at 53 sites throughout New Zealand. We found a high degree of correlation and convergence between biotic indices calculated from traditional biomonitoring techniques and from eDNA.

The Loss of Starlink Satellites in February 2022: How Moderate Geomagnetic Storms Can Adversely Affect Assets in Low‐Earth Orbit

open access: yesSpace Weather, Volume 22, Issue 4, April 2024.
Abstract On 3 February 2022, SpaceX launched 49 Starlink satellites, 38 of which unexpectedly de‐orbited. Although this event was attributed to space weather, definitive causality remained elusive because space weather conditions were not extreme.

Link-Layer Capacity of NOMA Under Statistical Delay QoS Guarantees [PDF]

open access: yes, 2018
In this paper, we study the achievable link-layer rate, namely, effective capacity (EC), under the per-user statistical delay quality-of-service (QoS) requirements, for a downlink nonorthogonal multiple access (NOMA) network with M users.

FEM amd BEM computing costs for acoustical problems

open access: yesArchives of Acoustics, 2014
FEM and BEM computing costs are compared for acoustical problems. The cost analysis was carried out for bounded areas of simple shapes for objects with acoustical losses (e.g. with sound absorbing materials).
