The synthesis of nonsymmetrical polyamines (PAs) has, up to now, been problematic due to lengthy synthetic procedures, lack of regioselectivity, and very poor atom economy. An innovative synthetic protocol for nonsymmetrical PAs using a modified Ugi reaction ( N-split Ugi) which simplifies the synthesis of these tricky compounds is described. We believe that this new synthesis may open the door...

This paper presents how a working prototype of a VLAN (Virtual LAN) and GVRP (Generic VLAN Registration Protocol) aware Ethernet switch for Linux can be built using a “Writing code is good but integrating existing code is much better” approach. The paper is split into two parts. The first part describes the development of the signalling component of the network: the GVRP daemon, the second part...

The Network Management Research Group (NMRG) started an activity to collect traces of the Simple Network Management Protocol (SNMP) from operational networks. To analyze these traces, it is necessary to split potentially large traces into more manageable pieces that make it easier to deal with large data sets and simplify the analysis of the data. This document introduces some common definition...

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...
