Visual Method for Detecting Contaminant on Dried Nutmeg Using Fluorescence Imaging

Repeatability of Detecting Visual Cortex Activity in Functional Magnetic Resonance Imaging

Introduction As functional magnetic resonance imaging (fMRI) is too expensive and time consuming, its frequent implementation is difficult. The aim of this study is to evaluate repeatability of detecting visual cortex activity in fMRI. Materials and Methods In this study, 15 normal volunteers (10 female, 5 male; Mean age±SD: 24.7±3.8 years) attended. Functional magnetic resonance images were ob...

Highly Sensitive FRET-Based Fluorescence Immunoassay for Detecting of Aflatoxin B1 Using Magnetic/Silica Core-Shell as a Signal Intensifier

Background: Recently, some new nanobiosensors using different nanoparticles or microarray systems for detection of mycotoxins have been designed . However, rapid, sensitive and early detection of aflatoxicosis would be very helpful to distinguish high-risk persons. Objectives: We report a highly sensitive competitive immunoassay using magnetic/silica core shell as a signal intensifier for the d...

A Novel Method for Detecting Targets on Inactive Radars Using an Adaptive Processing on the Ambiguity Function (RESEARCH NOTE)

In this paper a novel method for detecting targets in inactive radars is presented. In this method, the time history of cellsof the ambiguity function is used for detection. For this purpose, the cell history is considered as a random field. Then, using adaptive filter, the string time of the desired target are separated from the string time of noise and clusters in the environment. In order to...

A New 3d Fluorescence Imaging Method

Here we propose a novel fluorescence optical tomography method. In this method, ultrashort laser pulses are used to excite the fluorescent dye concentrated at the tumor region, and the temporal fluorescence light signals are detected around the boundaries of the target tissue. The temporal information of the fluorescence light intensity is employed to construct tomographic and 3D images of the ...
