Preparation of Proper Immunogen by Cloning and Stable Expression of cDNA coding for Human Hematopoietic Stem Cell Marker CD34 in NIH-3T3 Mouse Fibroblast Cell Line [PDF]

open access: yesAdvanced Pharmaceutical Bulletin, 2015
Purpose: Transmembrane CD34 glycoprotein is the most important marker for identification, isolation and enumeration of hematopoietic stem cells (HSCs). We aimed in this study to clone the cDNA coding for human CD34 from KG1a cell line and stably express ...

IMAGE COMPRESSION BY USING WALSH AND FRAMELET TRANSFORM

open access: yesMağallaẗ Al-kūfaẗ Al-handasiyyaẗ, 2019
In this paper, Framelet and Walsh transform are proposed for transformation, and then using arithmetic coding for compress an image. The goal is to achieve higher compression ratio by applying two levels Framelet transform (FLT), and then apply 2D Walsh ...

Joint source-channel coding for image transmission based on best wavelet packet

open access: yesTongxin xuebao, 2012
A novel joint source/channel image coding algorithm was proposed based on the best wavelet packet in a rate-distortion sense.Different from other wavelet packet image coding,the channel and the channel code information were introduced to the source ...

Coding gain in paraunitary analysis/synthesis systems [PDF]

open access: yes, 1993
A formal proof that bit allocation results hold for the entire class of paraunitary subband coders is presented. The problem of finding an optimal paraunitary subband coder, so as to maximize the coding gain of the system, is discussed.

Convolutional Sparse Coding Using Wavelets for Single Image Super-Resolution

open access: yesIEEE Access, 2019
In this paper, we propose the convolutional sparse coding based model in the wavelet domain for the task of single image super-resolution (SISR). The conventional sparse coding based approaches work on overlapping image patches and use the dictionary ...
