Convolutional Neural Networks (CNNs) have achieved comparable error rates to well-trained human on ILSVRC2014 image classification task. To achieve better performance, the complexity of CNNs is continually increasing with deeper and bigger architectures. Though CNNs achieved promising external classification behavior, understanding of their internal work mechanism is still limited. In this work...

We demonstrate the imaging of buried features in a microstructure—a tiny hole in an aluminum thin film covered by a chromium layer—with nanometer lateral resolution using a transient temperature distribution restricted to within ;0.5 mm of the sample surface. This is achieved by mapping photothermally induced megahertz surface vibrations in an atomic force microscope. Local thermal probing with...

BACKGROUND Biochemical markers harvested from gingival crevicular fluid (GCF) may be useful to identify and predict periodontal disease progression and to monitor the response to treatment. C-telopeptide pyridinoline cross-links (ICTP), a host-derived breakdown product specific for bone, and interleukin-1beta (IL-1), a potent bone-resorptive cytokine, have been associated with periodontal tissu...

Introduction: In the last two decades, studies have shown that periodontal disease affects a wide range of human organs. These diseases affect body organs through various mechanisms. This study was performed in order to analyze the association between periodontal disease and coronary artery diseases among patients attending SH.M.KH hospital in Ilam during 2015.Materials and Method: In the prese...

The surface accessibility of macromolecules plays a key role in modulating molecular recognition events. RNA is a complex and dynamic molecule involved in many aspects of gene expression. However, there are few experimental methods available to measure the accessible surface of RNA. Here, we investigate the accessible surface of RNA using NMR and the small paramagnetic molecule TEMPOL. We inves...

BACKGROUND This study aims to compare the periodontal health status of current smokers versus nonsmokers. The study was carried out in the Dental department, Pakistan Institute of Medical Sciences (PIMS) between May 2009 and June 2010. A total of 280 male subjects, married, over the age of 18 were selected to take part in the study and their periodontal health was assessed by presence of calcul...

AIM This study assessed the influence of current oral contraceptive pills on periodontal health in young females. METHODS AND MATERIALS Seventy women ranging in age from 17 to 35 years (mean 24 years) had a comprehensive periodontal examination. Their current and previous oral contraceptive pill use was assessed by a questionnaire. A periodontal assessment was performed that included recordin...

INTRODUCTION A tapered dental implant (Laser-Lok [LL] surface treatment) with a 2 mm wide collar, that has been laser micromachined in the lower 1.5 mm to preferentially accomplish bone and connective tissue attachment while inhibiting epithelial downgrowth, was evaluated in a prospective, controlled, multicenter clinical trial. MATERIALS Data are reported at measurement periods from 1 to 37 ...

This report outlines the experimental, surgical, and prosthodontic protocols for a prospective clinical trial using the Endopore dental implant to replace single maxillary teeth. Twenty patients (10 male, 10 female) ranging in age from 30 to 60 years each received one implant (mean length 10.1 mm), which, after an initial healing period of 4 months, was restored with a single crown. Records col...

BACKGROUND AND AIMS The main purpose of this study was to assess intra- and inter-examiner reproducibility of probing depth measurements with a manual periodontal probe. MATERIALS AND METHODS In this study, 32 dental students in Tabriz Faculty of Dentistry with normal periodontium were evaluated. Each tooth of the upper right quadrants, except the third molars, was examined. Probing depths we...
