Evaluation of the effects of different distalization systems on dentoalveolar structures in Class II malocclusions using finite element analysis
This study aimed to evaluate the movement pattern of two different distalization systems during the distalization of the maxillary dentition from the maxillary canine to the second molar tooth and the stresses in the periodontal ligament by anchoring the mandibular dentition using the finite element analysis method. A standard three-dimensional finite element model was created that simulates the mechanics planned to be implemented with maxillary and mandibular teeth, periodontal ligaments, cortical and trabecular bones. Two different distalization mechanics were applied to this model with the Carriere Distalizer appliance ...

Biomechanical behavior of deep anterior lamellar keratoplasty: a finite element analysis
Comput Methods Biomech Biomed Engin. 2023 Dec 11:1-10. doi: 10.1080/10255842.2023.2290459. Online ahead of print.ABSTRACTDeep Anterior Lamellar Keratoplasty (DALK) is a surgical procedure used to restore sight and manage corneal diseases by replacing cloudy corneal tissue with allogeneic normal corneal tissue or artificial corneal material. However, the limited availability and mechanical defects of artificial corneal materials pose challenges in DALK. To predicting postoperative mechanical behavior of Deep Anterior Lamellar Keratoplasty (DALK), a three-dimensional finite element model of the postoperative DALK cornea with...

Design and implementation of low power FPGA-based optimal multiband filter with Spline function for denoising ECG signals
This article presents the design and implementation of a low power FPGA-based optimal multiband filter with Spline function for denoising ECG signals. The proposed multiband filter design utilizes least mean square algorithm to determine the optimal filter coefficients for multiple frequency bands, while the Spline function is used to interpolate the filter coefficients within each band to achieve a smooth transition between adjacent bands. The experimental work is carried out with ECGID database and it shows that the proposed filter outperforms in terms of benchmark performance matrices SNR, MSE, CC and PRD. The filter is...

Effect of pre-stress on dynamic finite element analysis of the temporomandibular joint
Comput Methods Biomech Biomed Engin. 2023 Dec 11:1-11. doi: 10.1080/10255842.2023.2290455. Online ahead of print.ABSTRACTThe pre-stress of the temporomandibular joint (TMJ) at the intercuspal position (ICP) was often neglected, which would cause errors in the finite element analysis. The purpose of this study was to investigate the effect of pre-stress on dynamic finite element analysis of the TMJs. One healthy female adult was recruited for medical imaging and motion data acquisition of the reference position (RP) to the ICP and the clicking teeth. The three-dimensional maxillofacial model including the maxilla, mandible,...

Enhancing efficacy and safety of glioma treatment: optimization and evaluation of a novel dual-cavity capsule structure through orthogonal testing
Comput Methods Biomech Biomed Engin. 2023 Dec 11:1-13. doi: 10.1080/10255842.2023.2291637. Online ahead of print.ABSTRACTExisting glioma treatments face challenges in simultaneously combining radiotherapy and chemotherapy while achieving long-term, stable continuous irradiation at low doses. To address this clinical challenge, two types of radiochemotherapy integrated dual-cavity capsules, single-capsule dual-cavity, and dual-capsule dual-cavity, were designed in this research. We employed finite element simulation and the Monte Carlo method to conduct stress-deformation simulation and dose analysis on the structure and ma...

Exhaled breath signal analysis for diabetes detection: an optimized deep learning approach
In this study, a flexible deep learning system for breath analysis is created using an optimal hybrid deep learning model. To improve the quality of the gathered breath signals, the raw data are first pre-processed. Then, the most relevant features like Improved IMFCC, BFCC (bark frequency), DWT, peak detection, QT intervals, and PR intervals are extracted. Then, using these features the hybrid classifiers built into the diabetic's detection phase is trained. The diabetic detection phase is modeled with an optimized DBN and BI-GRU model. To enhance the detection accuracy of the proposed model, the weight function of DBN is...

The fatal effect of shock waves on the head of a person wearing a polyurea-reinforced ballistic helmet
Comput Methods Biomech Biomed Engin. 2023 Dec 7:1-14. doi: 10.1080/10255842.2023.2285240. Online ahead of print.ABSTRACTBallistic helmets are an important part of personal protective equipment in war and are specifically designed to protect a person's head. The future trend is to improve the protective performance of helmets through the use of lightweight coatings, and polyurea, as one of the hottest elastomeric polymer coating materials in recent years, has excellent physical properties, especially its ability to improve the target's protection against blast shock waves. Therefore, in this study, using a validated head mo...
