An image retrieval methodology suited for search in large collections of heterogeneous images is presented.The proposed approach employs a fully unsupervised segmentation algorithm to divide images into regions and endow red pygmy dogwood the indexing and retrieval system with content-based functionalities.Low-level descriptors for the color, posit
Bacterial infections, particularly hospital-acquired infections caused by Pseudomonas aeruginosa, have become a global emtek freestone finger pull threat with a high mortality rate.Gram-negative bacteria including P.aeruginosa employ N-acyl homoserine lactones (AHLs) as chemical signals to regulate the expression of pathogenic phenotypes through a
The effect of intermediate stress (in situ tunnel axial) on a strainburst is studied with a three-dimensional (3D) bonded block distinct element method (DEM).A series of simulations of strainbursts under true triaxial in situ stress conditions (i.e.high tangential stress, moderate intermediate stress and low radial stress) of near-boundary rock mas
Abstract The use of high strength aluminium alloys, such as 6XXX and 7XXX series, is continuously increasing for automotive applications in view of their good strength-to-weight ratio.Their formability at room temperature is limited and they are thus often formed at high temperatures to enable production of complex geometries.Critical challenges du
The retinal pigment epithelium (RPE) is a neural monolayer lining the back of the eye.Degeneration of the RPE leads to severe vision loss in, so far incurable, diseases such as age-related macular degeneration and some forms of retinitis pigmentosa.A promising future replacement therapy may be autologous iris epithelial cell transdifferentiation in
