Given a normal (multi-)modal logic Θ, a characterization is given of the finitely presentable algebras A whose logics LA split the lattice of normal extensions of Θ. This is a substantial generalization of [Rautenberg, 1980; Rautenberg, 1977] in which Θ is assumed to be weakly transitive and A to be finite. We also obtain as a direct consequence a result by [Blok, 1978] that for all cycle-free ...

Registration of multi-modal retinal images is very significant to integrate information gained from different modalities for a reliable diagnosis of retinal diseases by ophthalmologists. However, accurate image registration is a challenging, we propose an algorithm for registration of summed-voxel projection images (SVPIs) with color fundus photographs (CFPs) based on local patch matching. SVPI...

This paper argues that the notion of focal points is important in understanding bargaining processes. Recent literature confines a discussion of the usefulness of the notion to coordination problems and when bargaining experiments result in outcomes that are inconsistent with a straightforward interpretation of economic theory, some notion of ‘fairness’ is invoked. This paper uses symmetry requ...

We examine corresponding Cauchy-Riemann equations by using the non-commutativity for the product on split-biquaternions. Additionally, we describe the regularity of functions and properties of their differential equations on split-biquaternions. We investigate representations and calculations of the derivatives of functions of split-biquaternionic variables. c ©2016 all rights reserved.

Split-brain cats using a single hemisphere show impaired performance on a variety of behavioral tasks. This has been attributed to a loss of cortical mass action. To test this proposal in primates, performance on a nested match-to-sample task was compared in split-brain, hemispherectomized, and normal monkeys. As expected, split-brain monkeys using a single hemisphere performed worse than norma...

An understanding of relations between causes and effects is essential for making sense of the dynamic physical world. It has been argued that this understanding of causality depends on both perceptual and inferential components. To investigate whether causal perception and causal inference rely on common or on distinct processes, the authors tested 2 callosotomy (split-brain) patients and a gro...

Laterality experiments using reaction time were conducted to assess the performance of the right hemisphere of normal people on verbal tasks. The results show that if the task calls for pictorial encoding of visually presented verbal material, then the right hemisphere’s performance is superior to that of the left. When the task calls for linguistic analysis, the minor hemisphere displays no ap...

Sensory and cognitive functions were assessed in a right-handed male before and after partial and complete callosal commissurotomy. After the initial posterior section was made, there was no evidence of interhemispheric sensory transfer, although the left hemisphere did have access to stimulus-related semantic and episodic information from the right hemisphere. After the callosum was completely...
