Removal of jitter noise in 3D shape recovery from image focus by using Kalman filter
Abstract
In regard to Shape from Focus, one critical factor impacting system application is mechanical vibration of the translational stage causing jitter noise along the optical axis. This noise is not detectable by simply observing the image. However, when focus measures are applied, inaccuracies in the depth occur. In this article, jitter noise and focus curves are modeled by Gaussian distribution and quadratic function, respectively. Then Kalman filter is designed and applied to eliminate this noise in the focus curves, as a post‐processing step after the focus measure application. Experiments are implemented with si...

A novel classification scheme to decline the mortality rate among women due to breast tumor
Abstract
Early screening of skeptical masses or breast carcinomas in mammograms is supposed to decline the mortality rate among women. This amount can be decreased more on development of the computer‐aided diagnosis with reduction of false suppositions in medical informatics. Our aim is to provide a robust tumor detection system for accurate classification of breast masses using normal, abnormal, benign, or malignant classes. The breast carcinomas are classified on the basis of observed classes. This is highly dependent on feature extraction process. In propose work, a novel algorithm for classification based on the comb...

ATR ‐FTIR spectroscopy and μ‐EDXRF spectrometry monitoring of enamel erosion caused by medicaments used in the treatment of respiratory diseases
In this study, we evaluated the erosive capacity of four most commonly prescribed respiratory disease syrup medicaments on enamel using micro‐energy‐dispersive X‐ray fluorescence spectrometry (µ‐EDXRF) and attenuated total reflection Fourier transform infrared spectroscopy (ATR‐FTIR). Fifty‐five enamel fragments obtained from 30 bovine teeth were treated with artificial saliva (S), acebrofilin hydrochloride (AC), ambroxol hydrochloride (AM), bromhexine hydrochloride (BR), and salbutamol sulfate (SS); by immersing in 3 mL of respective solutions for 1 min, three times a day at intervals of 1 hr, for 5 days. µ...

Airyscan super ‐resolution microscopy of mitochondrial morphology and dynamics in living tumor cells
Abstract
Mitochondrial morphology is regulated by continuous fusion‐and‐fission events that are essential for maintaining normal function. Despite the prominence of mitochondrial function in energy generation and cell signaling, understanding of processes of fusion and fission dynamics has been hampered by the lack of high‐resolution optical systems that accommodate live‐cell imaging. We have examined different confocal modalities in terms of resolution and signal‐to‐noise ratio (SNR) in a point scanning confocal microscope with Airyscan super‐resolution (AS‐SR). Results indicated that Airyscan (AS) provide...

Effect of novel chelating agents on the push ‐out bond strength of calcium silicate cements to the simulated root‐end cavities
Abstract
To compare the effects of different chelating agents on the push‐out bond strength of calcium silicate‐based cements to the simulated root‐end cavities. Root‐end cavities were prepared on the roots of fifty extracted maxillary anterior teeth. The specimens were then randomly divided into 5 groups (n = 10) based on the final irrigation regimen: Group 1: 17% EDTA, Group 2: 7% maleic acid, Group 3: QMix, Group 4: 2.25% peracetic acid (PAA), Group 5: 0.9% saline. Then, the samples from each group were subdivided into two groups (n = 5) based on the apical filling material. In group 1, root‐end caviti...

Polymerization shrinkage and porosity profile of dual cure dental resin cements with different adhesion to dentin mechanisms
Abstract
This research aims to probe the porosity profile and polymerization shrinkage of two different dual cure resin cements with different dentin bonding systems. The self‐adhesive resin cement RelyX U200 (named RU) and the conventional Allcem Core (named AC) were analyzed by x‐ray microtomography (μCT) and Scanning Electron Microscopy (SEM). Each cement was divided into two groups (n = 5): dual‐cured (RUD and ACD) and self‐cured (RUC and ACC). μCT demonstrated that the method of polymerization does not influence the porosity profile but the polymerization shrinkage. Fewer concentration of pores was obser...

Effects of EDTA gel and chlorhexidine gel on root dentin permeability
Abstract
The aim of this study was to evaluate the effect of 24% ethylenediaminetetraacetic acid (EDTA) gel and 2% chlorhexidine gel (CHX) in dentin permeability and smear layer removal from root canals instrumented with NiTi rotary system using histochemical staining and scanning electron microscopy (SEM) analysis. Overall, 43 premolars were classified into two experimental groups, EDTA (n = 20) and CHX (n = 20), and a negative control (NC) (n = 3). All specimens were instrumented and the irrigant solutions were used after each file change. The EDTA group received a final rinse with 5‐ml 1% NaOCl followed by...

Natural enamel caries in quinoline: Volumetric data and the pattern of infiltration
In conclusion, αd was the main predictor of quinoline infiltration, but it differed from the water volume with a small effect size, and the pore volume fraction with quinoline was much lower than previous estimates.
Volume of oil infiltrated in enamel caries is presented for histological zones relevant for progress and reversal of caries.
Oil infiltrated < 50% of the enamel pore volume and it is well correlated with permeability but not with mineral content. (Source: Microscopy Research and Technique)

Jansen ‐MIDAS: A multi‐level photomicrograph segmentation software based on isotropic undecimated wavelets
Abstract
Image segmentation, the process of separating the elements within a picture, is frequently used for obtaining information from photomicrographs. Segmentation methods should be used with reservations, since incorrect results can mislead when interpreting regions of interest (ROI). This decreases the success rate of extra procedures. Multi‐Level Starlet Segmentation (MLSS) and Multi‐Level Starlet Optimal Segmentation (MLSOS) were developed to be an alternative for general segmentation tools. These methods gave rise to Jansen‐MIDAS, an open‐source software. A scientist can use it to obtain several segmentatio...

Adhesion, unfolding forces, and molecular elasticity of fibronectin coatings: An atomic force microscopy study
In this study we have investigated the adhesion and mechanical properties of fibronectin coatings. The coatings were also used to study the role of the residence time and the influence of the loading rate in nonspecific interactions. The results showed that the adhesion force between silica and fibronectin increased with loading rate delivering similar values for residence times of 1 and 2 s. Further analysis indicated that the distance to the transition state was about 0.5 nm. Moreover, the adhesion force did not vary with the loading rate for contact time of 0 s. The unfolding of fibronectin domains also depended of the ...
