New discretization method applied to NBV problem: Semioctree.
PloS one
Nov 1, 2018
This paper presents a discretization methodology applied to the NBV (Next Best View) problem, which consists of determining the heuristical best position of the next scan. This new methodology is a hybrid process between a homogenous voxelization and...
Identification of cervical cancer using laser-induced breakdown spectroscopy coupled with principal component analysis and support vector machine.
Lasers in medical science
Jun 26, 2018
Cervical cancer is one of the most widespread diseases in women. Traditional cancer diagnosis is extremely complicated and relies on subjective interpretation of biopsy material. In this work, laser-induced breakdown spectroscopy (LIBS) was used in c...
Laser Cutting as a Rapid Method for Fabricating Thin Soft Pneumatic Actuators and Robots.
Soft robotics
Jun 20, 2018
Pneumatically actuated soft robots address many challenges with interfacing with delicate objects, but these actuators/robots are still bulky and require many hours to fabricate, limiting their widespread use. This article reports a novel design and ...
Comparative microstructural analysis of bone osteotomies after cutting by computer-assisted robot-guided laser osteotome and piezoelectric osteotome: an in vivo animal study.
Lasers in medical science
Apr 13, 2018
Most industrial laser applications utilize computer and robot assistance, for guidance, safety, repeatability, and precision. In contrast, medical applications using laser systems are mostly conducted manually. The advantages can be effective only wh...
Carboxybetaine-modified succinylated chitosan-based beads encourage pancreatic β-cells (Min-6) to form islet-like spheroids under in vitro conditions.
Journal of materials science. Materials in medicine
Dec 30, 2017
In vitro, pancreatic β-cells tend to reduce their ability to aggregate into islets and lose insulin-producing ability, likely due to insufficient cell-cell and cell-matrix interactions that are essential for β-cell retention, viability and functional...

Antibacterial mechanisms of a novel type picosecond laser-generated silver-titanium nanoparticles and their toxicity to human cells.
International journal of nanomedicine
Dec 20, 2017
In this study, we explored the antibacterial mechanisms for a novel type of Ag-TiO compound nanoparticles (NPs) produced from an Ag-TiO alloy using a picosecond laser and evaluated the toxicity of the Ag-TiO NPs to a range of human cell types. Transm...
The potential of computer vision, optical backscattering parameters and artificial neural network modelling in monitoring the shrinkage of sweet potato (Ipomoea batatas L.) during drying.
Journal of the science of food and agriculture
Sep 11, 2017
BACKGROUND: Drying is a method used to preserve agricultural crops. During the drying of products with high moisture content, structural changes in shape, volume, area, density and porosity occur. These changes could affect the final quality of dried...
A neural controller for online laser power adjustment during the heat therapy process in the presence of nanoparticles.
Australasian physical & engineering sciences in medicine
Apr 10, 2017
The present research evaluated the efficiency of a control approach to control the temperature of a breast tumor mass in the presence of nanoparticles exposed to laser radiation. However, if the radiation is carried out in open loop manner it may res...
Online 3D Ear Recognition by Combining Global and Local Features.
PloS one
Dec 9, 2016
The three-dimensional shape of the ear has been proven to be a stable candidate for biometric authentication because of its desirable properties such as universality, uniqueness, and permanence. In this paper, a special laser scanner designed for onl...
Analyzing the performance of fluorescence parameters in the monitoring of leaf nitrogen content of paddy rice.
Scientific reports
Jun 28, 2016
Leaf nitrogen content (LNC) is a significant factor which can be utilized to monitor the status of paddy rice and it requires a reliable approach for fast and precise quantification. This investigation aims to quantitatively analyze the correlation b...
