Measuring Membership Privacy on Aggregate Location Time-Series [PDF]

open access: yes, 2020
While location data is extremely valuable for various applications, disclosing it prompts serious threats to individuals' privacy. To limit such concerns, organizations often provide analysts with aggregate time-series that indicate, e.g., how many ...

Information-theoretic analysis of realistic odor plumes: What cues are useful for determining location? [PDF]

open access: yesPLoS Computational Biology, 2018
Many species rely on olfaction to navigate towards food sources or mates. Olfactory navigation is a challenging task since odor environments are typically turbulent.

Sampling Males Who Inject Drugs in Haiphong, Vietnam: Comparison of Time-Location and Respondent-Driven Sampling Methods [PDF]

open access: yesJournal of Urban Health, 2015
Accurate measurements of HIV prevalence and associated risk factors among hidden and high-risk groups are vital for program planning and implementation. However, only two sampling methods are purported to provide representative estimates for populations without sampling frames: time-location sampling (TLS) and respondent-driven sampling (RDS).

Batch and sampling time exert a larger influence on the fungal community than gastrointestinal location in model animals: A meaningful case study

open access: yesFrontiers in Nutrition, 2022
Fungi play a fundamental role in the intestinal ecosystem and health, but our knowledge of fungal composition and distribution in the whole gastrointestinal tract (GIT) is very limited.

Diversity of culturable endophytic fungi vary through time in Manihot esculenta Crantz

open access: yesBrazilian Journal of Biology, 2022
Endophytic fungi are a ubiquituos group that colonize all plant species on earth. Studies comparing the location of endophytic fungi within the leaves and the sampling time in Manihot esculenta Crantz (cassava) are limited.

Investigating the role of task relevance during rhythmic sampling of spatial locations

open access: yesScientific Reports, 2023
Recently it has been discovered that visuospatial attention operates rhythmically, rather than being stably employed over time. A low-frequency 7–8 Hz rhythmic mechanism coordinates periodic windows to sample relevant locations and to shift towards other,

Island characteristics and sampling methodologies influence the use of stable isotopes as an ecosystem function assessment tool

open access: yesEcological Solutions and Evidence, 2021
Monitoring seabird‐derived nutrients on islands following invasive mammal eradications may provide a useful, cost‐ and time‐efficient indication of the recovery of ecosystem function; however, the technique has only been investigated on environmentally ...
