Unaddressed imbalance of multitemporal land cover (LC) data reduces deep learning (DL) model usefulness to forecast changes. To manage geospatial imbalance, there is a lack specialized cost-sensitive strategies available. Sample weights are typically derived from training instance frequencies, which disregard spatial pattern complexities. Therefore, this study proposes sample weighting approach...
Williams syndrome is a rare genetic disorder in which, it is claimed, language abilities are relatively strong despite mild to moderate mental retardation. Such claims have, in turn, been interpreted as evidence either for modular preservation of language or for atypical constraints on cognitive development. However, this review demonstrates that there is, in fact, little evidence that syntax, ...
The basis function theory of spatial representations explains how neurons i n the parietal cortex can perform nonlinear transformations from sensory to motor coordinates. The authors present computer simulations showing that unilateral parietal lesions leading to a neuronal gradient in basis function maps can account for the behavior of patients with hemineglect, including (a) neglect in line c...

Th is paper analyses the nature and causes of the patterns of inequality and poverty in India. Since the economic liberalization in the early 1990s, the evidence suggests increasing inequality (in both spatial and vertical terms) as well as persistent poverty. Th e macroeconomic policies possibly responsible for these trends include—fi scal tightening, regressive tax policies and expenditure cu...
Background: Sagittal imbalance is known as the main radiographic driver of disability in adult spinal deformity (ASD).In this study, the association of radiological spinopelvic parameters and clinical outcomes was evaluated following thecorrective surgery of sagittal imbalance, in order to explore the predictive ability of each parameter.Methods: A total of 23 patients, who underwent corrective...
We present a new algorithm for the eecient data-parallel implementation of spatial individual-or particle-based stochastic (i.e. Monte Carlo) simulations. The potential execution time saving achievable using this algorithm is critically dependent upon the degree of imbalance present in a given application. We have therefore developed a mathematical analysis of the general stochastic diierential...
We propose a distributed data structure for maintaining spatial data sets on message-passing, distributed memory machines. The data structure is based on orthogonal bisection trees and it captures relevant characteristics of parallel machines. The operations we consider include insertion, deletion, and range queries. We introduce parameters to control how much imbalance is tolerated at each pro...
