In this study, we propose a novel method to investigate P300 variability over different trials. The method incorporates spatial correlation between EEG channels to form a cooperative coupled particle filtering method that tracks the P300 subcomponents, P3a and P3b, over trials. Using state space systems, the amplitude, latency, and width of each subcomponent are modeled as the main underlying p...

To verify the eventual relationship between maxillary lateral incisor agenesis (MLIA) and one of the clinically established facial biotypes. The analysis was performed in and between 3 groups: individuals with MLIA, their relatives and a control population defined as “normal” or unaffected. Among these, a comparison between adults and growing individuals was also carried out. The dolicofacial b...

While stress is expected to increase developmental instability (DI), not all studies confirm this. This heterogeneity could in part be due to the use of subtle differences between the left and right side of bilateral symmetrical organisms to quantify DI, leading to large sampling error obscuring associations with DI. Traits that develop simultaneously more than twice (such as flower petals or b...

The effects of aging and brain damage on time perception are not well understood. In this study, we test the hypothesis that aging affects timing variability and that parietal damage affects timing magnitude. Young and healthy college-age students, older subjects, and a patient with bilateral parietal damage were assessed on their ability to estimate and produce time intervals ranging from four...

The novel reinforcement to the data glove based dynamic signature verification system, using the Photometric measurement values collected simultaneously from photo plethysmography (PPG) during the signing process is the emerging technology. Skilled forgers try to attempt the genuine signatures in many numbers of trials. The wide gap in the Euclidian distances between forgers and the genuine tem...

Materials and methods 740 joints of 74 healthy children (27 girls/47 boys), mean aged 11.3 years were examined with bilateral US in 5 preselected joints to assess the interobserver variability. In 17 of these children (6 girls/11 boys), mean aged 10.1 years, 170 joints was examined in an intraobserver substudy, with a 2 week interval between the first and second examination. All US measurements...

In the present research, we exploited a continuous hydrological simulation to investigate on key variables responsible of flood peak formation. With this purpose, a distributed hydrological model (DREAM) is used in cascade with a rainfall generator (IRP-Iterated Random Pulse) to simulate a large number of extreme events providing insight into the main controls of flood generation mechanisms. In...

Variations in the arterial pattern of upper limb are common and have been reported by several investigators [1–3]. The great variability of this arterial pattern may be attributed to the failure of regression of some paths of embryonic arterial trunks [2, 3]. The presence of superficial brachial artery and the usual pattern of its branching in the upper arm or forearm have also been reported wi...

hip fractures are one of the most common injuries which present to an orthopaedic surgeon. most of these cases are unilateral .bilateral simultaneous femur neck fracture is a rare occurrence. we report a case of a bilateral neck femur fracture in a 30 year male following a generalized tonic clonic seizure in view of its rarity and also to increase the awareness of such rare injuries. the patien...

A defining feature of the basal ganglia is their anatomical organization into multiple cortico-striatal loops. A central tenet of this architecture is the idea that local striatal function is determined by its precise connectivity with cortex, creating a functional topography that is mirrored within cortex and striatum. Here we formally test this idea using both human anatomical and functional ...
