Recent advances in serial block-face imaging using scanning electron microscopy (SEM) have enabled the rapid and efficient acquisition of 3-dimensional (3D) ultrastructural information from a large volume of biological specimens including brain tissues. However, volume imaging under SEM is often hampered by sample charging, and typically requires specific sample preparation to reduce charging a...

BACKGROUND AND OBJECTIVES This study compared the performance of family practice residents selected through the National Resident Matching Program (NRMP) with those selected outside the NRMP and that of US medical graduates (USMGs) versus international medical graduates (IMGs). METHODS Surveys were mailed to all 470 US family practice residencies asking Match status and USMG versus IMG status...

OBJECTIVE To investigate the impact of a weekly email based board review course on individual resident performance on the American Board of Pediatrics (ABP) General Pediatrics Certifying Examination for pediatric residents and, specifically, residents with low ABP In-training Examination (ITE) scores. METHODS Weekly board-type questions were emailed to all pediatric residents from 2004-2007. ...

There is intense interest in applying machine learning to problems of causal inference in healthcare, economics, education, and other fields. In particular, individuallevel causal inference has applications such as precision medicine and personalized advertising. We give a new theoretical analysis and family of algorithms for estimating individual treatment effect (ITE) from observational data....

The aim of this study is to evaluate the effect of preheating on composite resins’ mechanical and physical properties. Preheating of composite resins positively affects the degree of conversion, viscosity, microleakage, marginal adaptation, microhardness and color change however, the flexural strength is adversely affected.  

reduced adsorption of NO3–N and NH4–N by anionic and cationic resins, respectively. Kjonaas (1999) also Ion exchange resins have widely been used in mineralization studies observed no detectable effect of freezing on resin staof organic materials. However, the stability of resin (anionic and cationic) under changing physical environmental conditions is not bility. Lehmann et al. (2001) have obs...

The purpose of this research is to mine a large set of heterogeneous audiology data to create a decision support system (DSS) to choose between two hearing aid types (ITE and BTE aid). This research is based on the data analysis of audiology data using various statistical and data mining techniques. It uses the data of a large NHS (National Health Services, UK) facility. It uses 180,000 records...

ITE Journal / novEmbEr 2006 Foreword As former chair of the Pedestrian and Bicycle Council (PBC) of the Institute of Transportation Engineers (ITE), I received phone calls from people in all corners of the United States who were looking for information on their specific pedestrian and bicycle questions and needs. Although I did not tabulate all of the calls, several topics were common. Perhaps ...

BACKGROUND Bisphenol A (BPA) is an endocrine disruptor with potential toxicity. Composite resins may not contain pure BPA, but its derivatives are widely used. Several studies found doses of BPA or its derivatives in saliva or urine of patients after composite resin placement. OBJECTIVE The aims of this study were to establish an exhaustive list of composite resins marketed in Europe and thei...

Computer-aided design and computer-aided manufacturing (CAD/CAM) denture base manufacturers claim to produce their resin pucks under high heat and pressure. Therefore, CAD/CAM dentures are assumed to have enhanced mechanical properties and, as a result, are often produced with lower denture base thicknesses than conventional, manually fabricated dentures. The aim of this study was to investigat...
