Machine learning and pattern recognition methods have been used to diagnose Alzheimer's disease (AD) and mild cognitive impairment (MCI) from individual MRI scans. Another application of such methods is to predict clinical scores from individual scans. Using relevance vector regression (RVR), we predicted individuals' performances on established tests from their MRI T1 weighted image in two ind...

due to the algorithmic simplicity, cellular automata (ca) models are useful and simple methods in structural optimization. in this paper, a cellular-automaton-based algorithm is presented for simultaneous shape and topology optimization of continuum structures, using five-step optimization procedure. two objective functions are considered and the optimization process is converted to the single ...

We investigated residual brain damage in subjects who suffered severe traumatic brain injury (TBI) in childhood, and its relationship with declarative memory impairment. Magnetic resonance imaging (MRI) volumetric data and memory performance were compared between 16 adolescents with antecedents of severe TBI and 16 matched normal controls. Volumes of grey matter, white matter, cerebrospinal flu...

Abstract This author introduces the concept of Stepwise Strategy Approach (SSA) for dealing with a number of problems arises in the current age of technology. This new idea is combined with the knowledge of Grey Theory for adding flexibility to decision making process. Grey theory is useful for grasping the ambiguity exists in the utilized information and the fuzziness appears in the human judg...

issue of verbal abuse is very common all over the world. There is a wrong notion that this type of abuse is the least harmful and does not carry any disastrous consequences in terms of mental health. This is a wrong belief as it is now being reported more vigorously that such type of abuse is detrimental to mental health. Verbal abuse is in the form of offensive language, usage of swear words, ...

This article reports tests of the relationships between problematic Internet use (PIU), time spent using the Internet, and psychosocial problems from the two perspectives. Ten individual meta-analyses were first conducted to identify weighted mean correlations among the five variables included within the models. The correlations derived from the meta-analyses were subsequently used in path anal...

Introduction Different MRI methods have been applied with success to the investigation of structural changes induced by natural aging (Galluzzi 2008). However, when using a single methodology it might be difficult to disentangle the relative proportion of different types of alterations in different anatomical locations. In the present study, we measured simultaneously voxel-based morphometry (V...

BACKGROUND Interictal episodes of aggression are often reported in patients with epilepsy. Some have characteristics of what has been referred to as episodic dyscontrol or intermittent explosive disorder (IED). Although structural brain abnormalities are thought to play a part in the pathophysiology of aggression, there are few in vivo studies of structural cerebral changes in patients with epi...

Background—Interictal episodes of aggression are often reported in patients with epilepsy. Some have characteristics of what has been referred to as episodic dyscontrol or intermittent explosive disorder (IED). Although structural brain abnormalities are thought to play a part in the pathophysiology of aggression, there are few in vivo studies of structural cerebral changes in patients with epi...

Neuroimaging findings suggest that excessive Internet use shows functional and structural brain changes similar to substance addiction. Even though it is still under debate whether there are gender differences in case of problematic use, previous studies by-passed this question by focusing on males only or by using gender matched approach without controlling for potential gender effects. We des...
