We study a class of artificial neural networks in which a physics-like conservation law upon the activity of connected neurons is imposed at each time. We postulate that the modification of the network activities may be interpreted as a learning capability if a judicious conservation law is chosen. We illustrate our claim by modeling a rat behavior in a labyrinth: the exploration of the labyrin...

One of the current chief goals of regenerative medicine involves finding a way to overcome the lack of efficient treatments for thousands of diseases. Recently, increasing evidence indicates that genetic defects observed in patient somatic cells could be erased and/or alleviated by direct reprogramming toward pluripotency and recapitulated upon directed differentiation to specific cell lineages...

The membranous labyrinth of the inner ear develops from the otic capsule between the fourth and twelfth weeks of intrauterine life. The cartilage around the capsule differentiates into the osseous labyrinth at 6-7 weeks' gestation and, at that time, is separated from the membranous portion by the perilymphatic space (Dayal, Farkushidy and Kokshanian, 1973). As the vestibular system is older phy...

The attenuation of neutron dose equivalent in concrete labyrinths with rectangular bends was studied by means of neutron sources and rem counters. The number of bends, the length of each section, and the width of the labyrinth could be varied. The results of these measurements were compared with the dose equivalent attenuation found in a labyrinth at the DESY 7-GeV electron synchrotron, with pu...

Abstract Postgraduate research students (PGRs) experience disproportionately high levels of psychological distress. Many factors contribute to this poor mental wellbeing and relate each other in complex dynamic ways. However, the relationship between PGRs their supervisor(s) is known strongly affect former. This study explores health with a focus on role student—supervisor relationship. Using c...

surgery to remove some part of the inner ear is an effective intervention to relieve of symptoms. an informed care can decline the patient's fears, and also a pre-operating patient education can facilitate the patient’s recovery. patients, who are in a labyrinthectomy waiting list, feel a combination of anxiety and release. they have spent lots of time to find a treatment for their severe ...
