The easiness at which adversarial instances can be generated in deep neural networks raises some fundamental questions on their functioning and concerns on their use in critical systems. In this paper, we draw a connection between overgeneralization and adversaries: a possible cause of adversaries lies in models designed to make decisions all over the input space, leading to inappropriate highc...

Most research on human fear conditioning and its generalization has focused on adults whereas only little is known about these processes in children. Direct comparisons between child and adult populations are needed to determine developmental risk markers of fear and anxiety. We compared 267 children and 285 adults in a differential fear conditioning paradigm and generalization test. Skin condu...

Why should you help a competitor? Why should you contribute to the public good if free riders reap the benefits of your generosity? Cooperation in a competitive world is a conundrum. Natural selection opposes the evolution of cooperation unless specific mechanisms are at work. Five such mechanisms have been proposed: direct reciprocity, indirect reciprocity, spatial selection, multilevel select...

abstract background: committing an error is part of the human nature. no health care provider, despite the mastery of their skills, is immune from committing it. medical error in the labor and obstetrics wards as well as other health units is inevitable and reduces the quality of health care, leading to accident. sometimes these events, like the death of mother, fetus, and newborn, would be bey...

purpose: to evaluate refractive state in patients with unilateral congenital nasolacrimal duct obstruction. methods: in this descriptive prospective study, patients with unilateral congenital nasolacrimal duct obstruction scheduled for surgery were enrolled over a period of two years (2007-2009). cycloplegic refractive error in both eyes was measured under anesthesia before surgery (probing, si...

purpose: to determine the correlation between hand dominancy and eye dominancy with visual acuity and refraction in subjects with refractive errors. methods: this cross-sectional study includes 620 patients undergoing lasik. their refractive error (dry and cycloplegic), hand dominancy, eye dominancy (by hole-in-the-hand method) and visual acuity were determined. exclusion criteria were monocula...
