Advances, applications, and limitations of portable and rapid detection technologies for routinely encountered foodborne pathogens

Frontiers in Microbiology, 2022
Traditional foodborne pathogen detection methods are highly dependent on pre-treatment of samples and selective microbiological plating to reliably screen target microorganisms.

Combining multiple markers significantly increases the sensitivity and precision of eDNA‐based single‐species analyses

Environmental DNA, 2023
The analysis of environmental DNA (eDNA) is becoming integrated as an established biomonitoring tool, often characterized by detection limits exceeding those of conventional counterparts. However, further improving the sensitivity of these methods may be

Capacity limits in face detection [PDF]

Cognition, 2022
Face detection is a prerequisite for further face processing, such as extracting identity or semantic information. Those later processes appear to be subject to strict capacity limits, but the location of the bottleneck is unclear. In particular, it is not known whether the bottleneck occurs before or after face detection.

Limits of Detecting Extraterrestrial Civilizations

CoRR, 2021
The search for extraterrestrial intelligence (SETI) is a scientific endeavor which struggles with unique issues -- a strong indeterminacy in what data to look for and when to do so. This has led to attempts at finding both fundamental limits of the communication between extraterrestrial intelligence and human civilizations, as well as benchmarks so as ...
