This study evaluated the effects of blood contamination and decontamination methods during different steps of bonding procedures on the microtensile bond strength of two-step self-etch adhesives to dentin. Sixty extracted human molars were ground flat to expose occlusal dentin. The 60 molars were randomly assigned to three groups, each treated with a(More)
One of today's most important developing wireless technologies is Cognitive Radio (CR). In our current fixed-assignment spectrum management policy, much of the available frequencies go unused. CR aims to make use of this unutilized space to provide wireless broadband services. This paper aims to give a background to CR and describe the key players in(More)
Simple benign tumors can present as part of a syndrome with substantial mortality. Fibrofolliculomas are benign skin tumors most often associated with the Birt-Hogg-Dubé syndrome (BHDS). The most life-threatening complication of this syndrome is renal cancer and other major features include multiple lung cysts and spontaneous pneumothorax. We present the(More)
This article has been accepted for publication in a future issue of this journal, but has not been fully edited. Content may change prior to final publication. Abstract—This paper proposes a Self-Adaptive Interactive Navigation Tool (SAINT), tailored for cloud-based vehicular traffic optimization in road networks. The legacy navigation systems make vehicles(More)
Clinical guidelines suggest that suspicious pigmented lesions of the plantar or palmar area require biopsy for early detection of acral melanoma. We present here a case of acral lentiginous melanoma in which various melanocytic atypia was observed at each biopsy site, including focal melanocytic proliferation. We suggest that this atypical melanosis is part(More)
Inspired by the advancement of vehicular networks and increasing concerns on driving safety, this paper proposes a framework of Context-Awareness Safety Driving (CASD). In vehicular networks, vehicles communicate with each other and share a variety of information. By utilizing those capability, CASD provides vehicles with a class-based safety action plan(More)
In order to support efficient data services on vehicular networks, we propose a Data-oriented Cluster-based Media Access Control Protocol (DCMAC). For Intelligent Transportation Systems (ITS), the demand for data services is increasing. Furthermore, most of vehicles will be equipped with Dedicated Short-Range Communications (DSRC) devices in the near(More)
