In this paper, various prominent local and global descriptors are evaluated against each other for analyzing their performance on shape-based image retrieval. Local descriptors include Fourier descriptors, Weber’s local descriptor, local binary patterns, and local ternary patterns. The prominent global descriptors include moment invariants, generic Fourier(More)
A lot of research has been done in recognizing handwritten characters in many languages like Chinese, Arabic, Devnagari, Urdu and English. This paper focuses on the problem of recognition of isolated handwritten numerals in Gurumukhi script. We have used different feature extraction techniques such as projection histograms, background directional(More)
Text line segmentation is extremely important phase of OCR. Overlapped lines, skewed lines and connected components make the problem of line segmentation more complicated in Gurumukhi handwritten documents. The existence of these problems in handwritten text documents declines the performance of OCR system. In this paper, we present a technique to solve(More)
Building on the lead from antimalarial isonitriles 1-4 of marine origin, several easily accessible synthetic isonitriles were assessed for their antimalarial activity against Plasmodium falciparum (in vitro) and multidrug resistant Plasmodium yoelii in Swiss mice model (in vivo). Isonitrile 11 has shown promising activity in both these assays.
BACKGROUND Much attention has been recently focused on the role of cancer stem cells (CSCs) in the initiation and progression of solid malignancies. Since CSCs are able to proliferate and self-renew extensively due to their ability to express anti-apoptotic and drug resistant proteins, thus sustaining tumor growth. Therefore, the strategy to eradicate CSCs(More)
A series of artemisinin derived esters 7a-j, incorporating pharmacologically privileged substructure, such as biphenyl, adamantane and fluorene, have been prepared and evaluated for antimalarial activity against multidrug-resistant (MDR) Plasmodium yoelii nigeriensis by oral route. Several of these compounds were found to be more active than the(More)
Bone is the living composite biomaterial having unique structural property. Presently, there is a considerable gap in our understanding of bone structure and composition in the native state, particularly with respect to the trabecular bone, which is metabolically more active than cortical bones, and is readily lost in post-menopausal osteoporosis. We used(More)
