Spatial Updating Depends on Gravity [PDF]

Frontiers in Neural Circuits, 2020
As we move through an environment the positions of surrounding objects relative to our body constantly change. Maintaining orientation requires spatial updating, the continuous monitoring of self-motion cues to update external locations. This ability critically depends on the integration of visual, proprioceptive, kinesthetic, and vestibular ...

On Spatial and Platial Dependence: Examining Shrinkage in Spatially Dependent Multilevel Models [PDF]

Annals of the American Association of Geographers, 2018
Multilevel models have been applied to study many geographical processes in epidemiology, economics, political science, sociology, urban analytics, and transportation. They are most often used to express how the effect of a treatment or intervention may vary by geographical group, a form of spatial process heterogeneity.

Intensity-dependent spatial summation [PDF]

Journal of the Optical Society of America A, 1985
Psychophysical evidence indicates that, in the human retina, the size of the spatial-summation area decreases as illuminance increases. Such a relationship would be beneficial for the detection of spatial contrast in the presence of photon noise. We analyze an image-processing mechanism in which the area of a strictly positive point-spread function ...

Exploring spatiotemporal pattern in the association between short-term exposure to fine particulate matter and COVID-19 incidence in the continental United States: a Leroux-conditional-autoregression-based strategy

Frontiers in Public Health, 2023
BackgroundNumerous studies have demonstrated that fine particulate matter (PM2.5) is adversely associated with COVID-19 incidence. However, few studies have explored the spatiotemporal heterogeneity in this association, which is critical for developing ...

Spatial dependency of action simulation [PDF]

Experimental Brain Research, 2011
In this study, we investigated the spatial dependency of action simulation. From previous research in the field of single-cell recordings, grasping studies and from crossmodal extinction tasks, it is known that our surrounding space can be divided into a peripersonal space and extrapersonal space. These two spaces are functionally different at both the

PARRONDO GAMES WITH SPATIAL DEPENDENCE [PDF]

Fluctuation and Noise Letters, 2012
Toral introduced so-called cooperative Parrondo games, in which there are N ≥ 3 players arranged in a circle. At each turn one player is randomly chosen to play. He plays either game A or game B. Game A results in a win or loss of one unit based on the toss of a fair coin. Game B results in a win or loss of one unit based on the toss of a biased coin,

Proposal and validation of geostatistical-based metrics to quantify within-field variability [PDF]

Revista Brasileira de Ciência do Solo
Metrics are fundamental to quantify and classify the spatial dependence of soil and agricultural attributes. This study aimed to propose and validate metrics based on two distinct approaches, one additive, which considers the arithmetic mean of the ...

GEOSTATISTICAL MODELING OF SOYBEAN YIELD AND SOIL CHEMICAL ATTRIBUTES USING SPATIAL BOOTSTRAP [PDF]

Engenharia Agrícola, 2019
The goal of this study was to use the spatial bootstrap method to model the spatial dependence structure of soybean yield and soil chemical attributes in an agricultural area.

A Novel Approach to Processing Very-High-Resolution Spaceborne SAR Data With Severe Spatial Dependence

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
An innovative approach, mainly featured by progressive iteration of partitioning and focusing, to processing very-high-resolution spaceborne synthetic aperture radar (SAR) data is presented in this article. Due to the long integration time endured during

PARRONDO GAMES WITH SPATIAL DEPENDENCE II [PDF]

Fluctuation and Noise Letters, 2012
Let game B be Toral's cooperative Parrondo game with (one-dimensional) spatial dependence, parameterized by N ≥ 3 and p0, p1, p2, p3 ∈ [0, 1], and let game A be the special case p0 = p1 = p2 = p3 = 1/2. In previous work we investigated μB and μ(1/2, 1/2), the mean profits per turn to the ensemble of N players always playing game B and always playing ...
