Until now, most of works about Spatial Reasoning focused on artificial objects. This paper addresses Spatial Reasoning in the game of Go that is a domain where the objects look like "natural". Two criterias toward a definition of "natural" objects is proposed : fractal structure of objects and dependency between genesis and use of objects. Combinatorial complexity of the game of Go obliges the ...

We consider the problem of clustering grouped and functional data, which are indexed by a covariate, and assessing the dependency of the clustered groups on the covariate. We assume that each observation within a group is a draw from a mixture model. The mixture components and the number of such components can change with the covariate, and are assumed to be unknown a priori. In addition to lea...

We investigate the impact of large floods on civil conflict in a sample of 125 countries between 1985 and 2009, employing GDP growth as a potential transmission channel. We instrument for floods and control for potential spatial and temporal dependency of civil conflict. We find that floods increase the probability of conflict incidence through their effect on GDP growth.

We predict the formation of optical spatial solitons in photorefractive polymers. The orientational enhancement from the doped chromophores and the dependency of the quantum efficiency of generating mobile holes on the electric field make the polymeric solitons behave differently from other photorefractive solitons.

A principal component regression (PCR) based approach for studying the functional connectivity of blood oxygenation level dependent (BOLD) responses of functional magnetic resonance imaging (fMRI) is proposed. The temporal dependency of BOLD responses from different spatial areas is determined from the eigenvectors of the correlation matrix.

The aim of this study is to investigate if the use of individual, per segment reference values for cardiac strain allows for improved discrimination of pathological deformation. In a cohort of patients with a high likelihood of ischemic heart disease, preliminary results within the subgroup of patients without pathological findings on cardiac MRI suggest a spatial dependency of strain.

We propose a combined spatial and non-spatial probabilistic modeling methodology motivated by an inspection task performed by a group of miniature robots. Our models explicitly consider spatiality and yield accurate predictions on system performance. An agent’s spatial distribution over time is modeled by the Fokker–Planck diffusion model and complements current non-spatial microscopic and macr...

This paper presents the process of derivation and development of a spatial multinomial logit model and its application to a housing type choice problem. Over the past few years, a relatively small body of research was developed that tries to capture the spatial and temporal dependencies across decision-makers and alternatives. While temporal dependencies are often considered especially in dynam...

We characterised the spatial structure of soil microbial communities in an unimproved grazed upland grassland in the Scottish Borders. A range of soil chemical parameters, cultivable microbes, protozoa, nematodes, phospholipid fatty acid (PLFA) profiles, community-level physiological profiles (CLPP), intra-radical arbuscular mycorrhizal community structure, and eubacterial, actinomycete, pseudo...
