An Intelligent Safety System for Human-Centered Semi-Autonomous Vehicles
Nowadays, automobile manufacturers make efforts to develop ways to make cars
fully safe. Monitoring driver's actions by computer vision techniques to detect
driving mistakes in real-time and then planning for autonomous driving to avoid
vehicle collisions is one of the most important issues that has been
investigated in the machine vision and Intelligent Transportation Systems
(ITS). The main goal of this study is to prevent accidents caused by fatigue,
drowsiness, and driver distraction. To avoid these incidents, this paper
proposes an integrated safety system that continuously monitors the driver's
attention and vehicle surroundings, and finally decides whether the actual
steering control status is safe or not. For this purpose, we equipped an
ordinary car called FARAZ with a vision system consisting of four mounted
cameras along with a universal car tool for communicating with surrounding
factory-installed sensors and other car systems, and sending commands to
actuators. The proposed system leverages a scene understanding pipeline using
deep convolutional encoder-decoder networks and a driver state detection
pipeline. We have been identifying and assessing domestic capabilities for the
development of technologies specifically of the ordinary vehicles in order to
manufacture smart cars and eke providing an intelligent system to increase
safety and to assist the driver in various conditions/situations.Comment: 15 pages and 5 figures, Submitted to the international conference on

Cold-induced urticaria with a familial transmission: a case report and review of the literature
Abstract Introduction Cryopyrin-associated periodic syndrome is a rare genetic disorder causing cold-induced urticaria, severe arthralgias, and (potentially) renal failure and hearing loss. Therapies that effectively control the symptoms and prevent the complications of this debilitating disorder are now available, making recognition of this disease important. Case presentation A 60-year-old Caucasian woman presented with complaints of rash and joint pains to a general medicine clinic. Her history showed that her symptoms were linked to cold exposure, but the results of a cold stimulation time test were negative. Several generations of her family had similar symptoms. Conclusions This case highlights the importance of considering cryopyrin-associated periodic syndrome in the differential diagnosis of cold-induced urticaria. Several medications targeting interleukin-1-beta are available, providing significant relief from symptoms and improvement in quality of life in affected patients.</p
What lies beneath: A comparison of reading aloud in pure alexia and semantic dementia
Exaggerated effects of word length upon reading aloud performance define Pure Alexia, but
have also been observed in Semantic Dementia. Some researchers have proposed a readingspecific
account, whereby performance in these two disorders reflects the same cause:
impaired orthographic processing. In contrast, according to the primary systems view of
acquired reading disorders, Pure Alexia results from a basic visual processing deficit,
whereas degraded semantic knowledge undermines reading performance in Semantic
Dementia. To explore the source of reading deficits in these two disorders, we compared the
reading performance of 10 Pure Alexic and 10 Semantic Dementia patients, matched in terms of overall severity of reading deficit. The results revealed comparable frequency effects on
reading accuracy, but weaker effects of regularity in Pure Alexia than Semantic Dementia.
Analysis of error types revealed a higher rate of letter-based errors and a lower rate of
regularisation responses in Pure Alexia than Semantic Dementia. Error responses were most
often words in Pure Alexia but most often nonwords in Semantic Dementia. Although all
patients made some letter substitution errors, these were characterised by visual similarity in
Pure Alexia and phonological similarity in Semantic Dementia. Overall, the data indicate
that the reading deficits in Pure Alexia and Semantic Dementia arise from impairments of
visual processing and knowledge of word meaning, respectively. The locus and mechanisms
of these impairments are placed within the context of current connectionist models of
reading

A preliminary study of genetic factors that influence susceptibility to bovine tuberculosis in the British cattle herd
Associations between specific host genes and susceptibility to Mycobacterial infections such as tuberculosis have been reported in several species. Bovine tuberculosis (bTB) impacts greatly the UK cattle industry, yet genetic predispositions have yet to be identified. We therefore used a candidate gene approach to study 384 cattle of which 160 had reacted positively to an antigenic skin test (‘reactors’). Our approach was unusual in that it used microsatellite markers, embraced high breed diversity and focused particularly on detecting genes showing heterozygote advantage, a mode of action often overlooked in SNP-based studies. A panel of neutral markers was used to control for population substructure and using a general linear model-based approach we were also able to control for age. We found that substructure was surprisingly weak and identified two genomic regions that were strongly associated with reactor status, identified by markers INRA111 and BMS2753. In general the strength of association detected tended to vary depending on whether age was included in the model. At INRA111 a single genotype appears strongly protective with an overall odds ratio of 2.2, the effect being consistent across nine diverse breeds. Our results suggest that breeding strategies could be devised that would appreciably increase genetic resistance of cattle to bTB (strictly, reduce the frequency of incidence of reactors) with implications for the current debate concerning badger-culling
Dioxin Toxicity In Vivo Results from an Increase in the Dioxin-Independent Transcriptional Activity of the Aryl Hydrocarbon Receptor
The Aryl hydrocarbon receptor (Ahr) is the nuclear receptor mediating the toxicity of dioxins -widespread and persistent pollutants whose toxic effects include tumor promotion, teratogenesis, wasting syndrome and chloracne. Elimination of Ahr in mice eliminates dioxin toxicity but also produces adverse effects, some seemingly unrelated to dioxin. Thus the relationship between the toxic and dioxin-independent functions of Ahr is not clear, which hampers understanding and treatment of dioxin toxicity. Here we develop a Drosophila model to show that dioxin actually increases the in vivo dioxin-independent activity of Ahr. This hyperactivation resembles the effects caused by an increase in the amount of its dimerisation partner Ahr nuclear translocator (Arnt) and entails an increased transcriptional potency of Ahr, in addition to the previously described effect on nuclear translocation. Thus the two apparently different functions of Ahr, dioxin-mediated and dioxin-independent, are in fact two different levels (hyperactivated and basal, respectively) of a single function
The Transfer of Evolved Artificial Immune System Behaviours between Small and Large Scale Robotic Platforms
This paper demonstrates that a set of behaviours evolved in simulation on a
miniature robot (epuck) can be transferred to a much larger scale platform (a
virtual Pioneer P3-DX) that also differs in shape, sensor type, sensor
configuration and programming interface. The chosen architecture uses a
reinforcement learning-assisted genetic algorithm to evolve the epuck
behaviours, which are encoded as a genetic sequence. This sequence is then used
by the Pioneers as part of an adaptive, idiotypic artificial immune system
(AIS) control architecture. Testing in three different simulated worlds shows
that the Pioneer can use these behaviours to navigate and solve object-tracking
tasks successfully, as long as its adaptive AIS mechanism is in place.Comment: 12 pages, 3 figures, 2 tables, 9th International Conference on
