Check out this month’s instructional video—“Red reflex.” Testing the red reflex is a simple and efficient way for FPs and pediatricians to rapidly screen children for ophthalmic conditions that, if left untreated, could lead to irreversible visual loss, blindness, and even death. By using a direct ophthalmoscope, readily available in the primary care physician’s office, the practitioner illumin...

The aim of this study is to investigate the improvement in strength a top-hat profile hollow-section beam used vehicle structure by attaching different shapes internal reinforcements. base was first considered as hat-shape which jointed flat plate using spot-welds. Three types sheet metal reinforcements were formed and attached inside beam’s structure. Then, they tested experimentally under low...

Near side impact crashes – especially pole impacts – have the potential to induce antero-lateral oblique loads to the chest. Current side impact dummies and most laboratory experimental studies have been designed to assess direct lateral impacts. A recent analysis of real world crashes indicated that the human chest experiences oblique loading in side impact crashes – in particular crashes into...

A way to classify the security level of a cryptographic device is to estimate the effort an adversary has to invest in an attack to be successful. While there are metrics and mathematical models to determine the complexity of attacks on cryptographic algorithms and protocols, estimating the security level of an implementation is more complicated. This is because attacks on the implementation de...

All cumulative semantic interference is not equal: A test of the Dark Side Model of lexical access

This paper presents the results of a study on crash conditions and occupant characteristics in side impacts to support the development of advanced side impact test procedures. The US vehicle fleet has been changing in recent years with a growing population of light trucks and vans, and the rapid introduction of side impact inflatable restraints for both thoracic and head protection. The study u...
