Efficient Sample Location Selection for Query Zone in Geo-Social Networks

open access: yesComplexity, 2021
While promoting a business or activity in geo-social networks, the geographical distance between its location and users is critical. Therefore, the problem of Distance-Aware Influence Maximization (DAIM) has been investigated recently.

Accommodating sampling location uncertainty in continuous phylogeography [PDF]

open access: yesVirus Evolution, 2022
AbstractPhylogeographic inference of the dispersal history of viral lineages offers key opportunities to tackle epidemiological questions about the spread of fast-evolving pathogens across human, animal and plant populations. In continuous space, i.e.

Intensity-Based Location Sampling Method For Investigating Socio-Economic Challenges: Ensuring External Validity In Surveys of Unknown Populations [PDF]

open access: yesSocioEconomic Challenges
Timely, representative evidence on users of public spaces and emergent venues is essential for diagnosing and addressing socioeconomic challenges. The Intensity-Based Location Sampling (ILS) method was developed to ensure the representativeness of ...

Use of fluorescence imaging to optimize location of tissue sampling in hard-to-heal wounds

open access: yesFrontiers in Cellular and Infection Microbiology, 2023
IntroductionWound microflora in hard-to-heal wounds is invariably complex and diverse. Determining the interfering organisms(s) is therefore challenging.

Semiparametric location estimation under non‐random sampling [PDF]

open access: yesStat, 2012
We study a class of semiparametric skewed distributions arising when the sample selection process produces non‐randomly sampled observations. Based on semiparametric theory and taking into account the symmetric nature of the population distribution, we propose both consistent estimators, i.e. robust to model mis‐specification, and efficient estimators,

Sampling experience in a cherry plantation

open access: yesInternational Journal of Horticultural Science, 2011
Experiments in a cherry plantation were performed to find out that samples taken from various parts of the foliage of the tree what extent represent the whole tree. One tree from three different cherry varieties was selected.

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 ...

CONTROL BY SAMPLE LOCATION IN PIGEONS' MATCHING TO SAMPLE [PDF]

open access: yesJournal of the Experimental Analysis of Behavior, 1998
Three experiments assessed the impact of sample location in pigeons' matching to sample. Experiments 1 and 2 demonstrated that after line or hue identity matching was acquired to high levels of accuracy with center‐key samples, varying sample location across the three keys disrupted performances.
