Biometric Fusion and Recognition

Biometric is the science and technology of measuring and analyzing biological data of human body, extracting a feature set from the acquired data and comparing this set against the template set in the database. In this paper, Recognition through fusion of face and iris biometric images based on wavelet features and Kernel Fisher Discriminant Analysis (KFDA) is developed. Discrete Wavelet Transform (DWT) of face and iris image is used to reduce the dimensions which help to prevent from requirement of storage space of database. Nearest Neighbour classifier is selected to assign class to its nearest neighbour. Then, nonlinear original input space can be converted through a nonlinear map function into a linear high-dimensional feature space with the use of KFDA

Chronic mechanical irritation and oral squamous cell carcinoma: A systematic review and meta-analysis

The objective of the present article was to qualitatively and quantitatively review the association between chronic mechanical irritation and oral squamous cell carcinoma (OSCC). PubMed, SCOPUS, and Web of Science databases were searched using the keyword combinations “chronic trauma and oral squamous cell carcinoma; chronic irritation and oral squamous cell carcinoma; chronic irritation and oral cancer; and chronic trauma and oral cancer.” Duplicates and irrelevant articles were excluded after the title and abstract screening. The full texts of the remaining articles were assessed using selection criteria. A total of 375 (PubMed-126; SCOPUS-152; WOS-97) articles were screened, and 343 duplicates and irrelevant articles were excluded from the study. Only 9 of the remaining 32 articles met the selection criteria and were included in the qualitative analysis. Buccal mucosa and tongue, being highly prone to chronic irritation through the dental prosthesis, were the common sites for OSCC. Edentulous subjects with ill-fitting dentures were at a high risk of developing chronic irritation associated-OSCC. According to the Joanna Briggs Institute of risk assessment, eight of the nine included studies had a low risk of bias. The quantitative analysis showed a significant association (p < 0.00001) between the chronic oral mucosal irritation and OSCC with an overall risk ratio of 2.56 at a confidence interval of 1.96-3.35. Chronic oral mucosa irritation has a significant association with OSCC, and the nature of association could be that of a potential co-factor (dependent risk factor) rather than an independent risk factor

Reply to the letter regarding “Chronic mechanical irritation and oral squamous cell carcinoma: A systematic review and meta-analysis”

Dear Editor, We thank Dr. Jian Xie for the valuable inputs on our paper titled ‘Chronic mechanical irritation and oral squamous cell carcinoma: A systematic review and meta-analysis [1].’ The first concern of Dr. Xie was that we had included two studies that were based on the same population. We re-examined these papers, one was published in 2010 [2] and the other in 2017 [3] by the same group of authors. Given the significant time difference between the two papers, we did not want to presume they were from the same sample population. There is no clear evidence that they are from the same sample population. Read more in PDF

Robust estimation of bacterial cell count from optical density

Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals &lt;1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data

Synthesis of solution processed f-CNT@Bi2S3 hybrid film coated linen fabric as a free-standing textile structured photo catalyst

A unique metallic carbon hybrid film, synthesized with synchronized distribution of bismuth sulfide (Bi2S3) and exfoliated multiwall carbon nanotubes (MWCNTs), has been proposed for use as freestanding textile electrodes in photo catalysts. The defect-rich morphology of Bi2S3 nanowire decorated MWCNT hybrid enhances the photocatalytic activity, electronic properties, cyclic stability, and electron pathways. The proposed f-CNT@Bi2S3-hybrid linen fabric electrode demonstrated a defect-rich morphology synchronized with high electrical conductivity. These properties greatly enhanced the photocatalytic activity and electron transfer. The high photocatalytic activity is attributed to the synergistic effect of the high electron affinity of MWCNTs and the structural distortion caused by Bi2S3 nanowires. Degradation of methylene blue dye was accelerated owing to the elevated activity of Bi2S3 nanowires, which provides fast absorption of contaminants and reduction of oxidative species. Our proposed system of metallic carbon freestanding textile electrode opens the broad applications of textile-based photochemical devices.This work was supported by the Korea Research Fellowship Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Science and ICT (2017H1D3A1A01055133)

Two days National Conference -VISHWATECH 2014 Heterogeneous Catalysts for Biodiesel Synthesis By Transesterification

Abstract-This review focuses on the heterogeneous base-catalyzed Trans esterification in terms of catalyst development, based on the published research, especially over the last decade. Heterogeneous base catalysis is the most viable process for the Trans esterification of triglyceride into biodiesel. The research and development on heterogeneous base catalysis for biodiesel synthesis have focused mainly on improving its slow reaction rate up to the level of its homogeneous counterpart. The heterogeneous catalysis features lower corrosiveness, environmental friendliness, easy catalyst recovery and high process integrity, all at levels superior to those of homogeneous catalysis

SUCCINYLCHOLINE CAUSING CARDIAC ARREST

A case history of a 45 year old male is presented, who suffered a cardiac arrest following the administration of a single dose of succinylcholine. The arrest was associated with hyperkalemia and massive elevation of serum creatine phosphokinase. Asystole was prolonged and refractory to treatment, although cardiac activity was eventually restored. The possible cause of the circulatory collapse is discussed and reports of similar cases reviewed

Automatic Recognition Of Traffic Signs Using Fann And Opencv

Automation Recognition of Traffic Signs is integrated and automation software for Traffic Symbol Recognition. The proposed system detects candidate regions as Maximally Stable Extremely Region (MSERs), which offers robustness to variations in lighting conditions. Recognition is based on Artificial Neural Network (ANN) classifiers. The training data are generated from real footage road signs which will be fetched using camera board and by applying threshold values we get proper training data for each frame. By applying thinning mechanism like erode and corrode and segmentation we can recognize proper shape and symbol. The proposed system is accurate at high vehicle speeds, operates under a range of weather conditions, runs at an average speed of 10 frames per second, and recognizes all classes of ideogram-based (non-text) traffic symbols from real footage road signs. Comprehensive comparative results to illustrate the performance of the system are presented

Efficacy of scaffold-mediated localized chemotherapy in cancer: a systematic review of current research

Objective: To assess the efficacy of scaffold-mediated localized chemotherapy in cancer. Methods: Databases including PubMed, Cochrane Library, and SCOPUS were searched for articles reporting the use of scaffold-mediated localized drug delivery in cancer. Essential data including scaffold fabrication material and methods, drug dosage and release duration and its effect on the cancer cells were extracted. Results: 15 articles out of 60 screened, fulfilled the eligibility criteria. Among the 15 studies, 5 studies included only cell lines and 2 studies were on mouse models, while 8 studies involved a combination of cell lines and mouse models. Scaffold materials included both synthetic polymers such as poly-lactide, polycaprolactone and natural materials including d-periosteum and human micro-fragmented adipose tissueA wide number of other variables included the fabrication procedure, drugs used, and the methods used to assess the effects on cancer. As a result, it was not possible to make any direct comparison of the efficacy of the therapeutic strategy used in each of these studies. Conclusion: Irrespective of the many variables, a common consensus in all the included studies was that scaffold mediated localized drug delivery effectively reduced cancer cell viability by increasing drug bioavailability to the target tissue, while its localized effect reduced the risk of systemic toxicity
