Wandering spleen is a rare condition with a reported incidence of less than 0.5% in which the spleen migrates from its normal anatomical location to any other position in the abdomen. Women constitute 80% of cases and one third of the overall patients are children. It has different clinical presentations such as asymptomatic, painless mass in the abdomen, intermittent abdominal pain and acute a...

In this Comment, we contrast different conceptions of mind wandering that were presented in two recent theoretical reviews: Smallwood and Schooler’s (2006) The Restless Mind and Watkins’s (2008) Constructive and Unconstructive Repetitive Thought. We also introduce a new perspective on the role of executive control in mind wandering by integrating empirical evidence presented in Smallwood and Sc...

Background: Dementia is an important public health concern, affecting approximately 50 million people world- wide. The term "wandering" generally associated with negative behaviours among persons dementia; however, physical movements of wandering can benefit dementia. Despite its common usage, the does not have a standardized definition. aim this study was to examine definitions in academic lit...

A wandering liver is a rare development in both the adult and pediatric population where the liver is freely displaced along a transverse axis. We describe the first known occurrence in published literature of a wandering liver in an adult individual who also had an intestinal malrotation complicated by a midgut volvulus. The abnormal ability for a liver to wander presents a highly unusual anat...

In this article we discuss our approach to the evolution of wandering behavior in a multi agent system (MAS). Our discussion covers the various aspects of the system setup, the performed experiments and the interpretation of the results observed. Utilizing a genetic algorithm (GA) and multi layer perceptrons (ANN) we show how wandering behavior is developed provided a single fitness criterion. ...

The 'wandering spleen' is a rare condition due to extreme laxity or absence of ligaments that fix the organ in its normal anatomical position within the left upper quadrant. Without early surgical intervention, wandering spleen can lead to torsion and subsequent splenic infarction or rupture. Clinical suspicion plus urgent investigation and intervention are important, so as to salvage the splee...

Wandering spleen is a rare clinical entity characterised by splenic hypermobility resulting from laxity or maldevelopment of the suspensory gastrosplenic, splenorenal, and phrenicocolic ligaments. Diagnosis is quite difficult, especially in children because of the lack of symptoms and signs until splenic torsion have occurred. An array of investigations is possible but US with color Doppler, CT...

This article investigates the relation between mind wandering and the spacing effect in inductive learning. Participants studied works of art by different artists grouped in blocks, where works by a particular artist were either presented all together successively (the massed condition), or interleaved with the works of other artists (the spaced condition). The works of 24 artists were shown, w...

Converging evidence from neuroscience suggests that our attention to the outside world waxes and wanes over time. We examined whether these periods of "mind wandering" are associated with reduced cortical analysis of the external environment. Participants performed a sustained attention to response task in which they responded to frequent "nontargets" (digits 0-9) and withheld responses for inf...

Let T be a finite subset of the complex unit circle S, and define f : S 7→ S by f(z) = z. Let CH(T ) denote the convex hull of T. If card(T ) = N ≥ 3, then CH(T ) defines a polygon with N sides. The N -gon CH(T ) is called a wandering N -gon if for every two non-negative integers i 6= j, CH(f (T )) and CH(f (T )) are disjoint N -gons. A non-degenerate chord of S is said to be critical if its tw...
