-In this paper we have compared WDR-ROI (Wavelet Difference Reductionregion of interest) concept and ASWDR-ROI (Adaptively Scanned Wavelet Difference Reduction-region of interest) algorithm. The term difference reduction refers to the way in which WDR encodes the locations of significant wavelet transform values. The WDR algorithm combines run-length coding of the significance map with an effic...
This paper describes methods for adapting the scanning order through wavelet transform values used in the Wavelet Difference Reduction (WDR) algorithm of Tian and Wells. These new methods are called Adaptively Scanned Wavelet Difference Reduction (ASWDR). ASWDR adapts the scanning procedure used by WDR in order to predict locations of significant transform values at half thresholds. These metho...
This is an attempt to devise a memory efficient WDR (Wavelet Difference Reduction) algorithm by decomposing a matrix using customized Echelon algorithm and applying WDR on it in parts. The standard process of WDR algorithm requires the entire matrix to be available in RAM (random access memory) which might not be feasible always or for a longer duration till the entire matrix is encoded. This i...

In this we have done hybridization of these two techniques in order to achieve higher compression rate an...
BACKGROUND To learn more about pain mechanisms produced by surgery, responses of wide dynamic range (WDR) and high threshold (HT) dorsal horn neurons were studied before and after an incision. For this study, an incision was made in a mechanically insensitive area of the receptive field (RF) of the dorsal horn neuron in the plantar aspect of the foot and changes in mechanical response propertie...
Conventional design method of the downhole tractor is based on cementing casing, which only suitable for smooth wellbore. For open hole well, conventional has poor adaptability and even cannot work normally. In order to improve obstacle surmounting performance wheeled (WDR) expand application range WDR, a double push rod-double spring support adjustment mechanism (DPRDSSAM) proposed in this pap...
Locations and response characteristics of nociceptive neurons in the dorsal horn of the spinal cord were studied in urethane-chloralose anesthetized Japanese macaques. There were two general categories of nociceptive neurons. Neurons of the first type, nociceptive specific (NS) neurons, responded only to intense mechanical stimuli. Neurons of the second type, wide dynamic range (WDR) neurons, w...
WD40 repeat (WDR) proteins are pleiotropic molecular hubs. We identify a WDR gene that is a conserved genomic neighbor of a chitin synthase gene in Ascomycetes. The WDR gene is unique to fungi and plants, and was called Fungal Plant WD (FPWD). FPWD is within a cell wall metabolism gene cluster in the Ascomycetes (Pezizomycotina) comprising chsD, a Chs activator and a GH17 glucanase. The FPWD, A...
The hermaphrodite germline of Caenorhabditis elegans initially engages in spermatogenesis and then switches to oogenesis during late stages of larval development. TRA-1, a member of the Ci/Gli family of transcriptional repressors, plays an essential role in this switch by repressing genes that promote spermatogenesis. WDR5 proteins are conserved components of histone methyltransferase complexes...
BACKGROUND There is growing evidence supporting a role for TRPA1 receptors in the neurotransmission of peripheral mechanical stimulation. In order to enhance understanding of TRPA1 contributions to mechanotransmission, we examined the effects a selective TRPA1 receptor antagonist, A-967079, on spinal neuronal activity following peripheral mechanical stimulation in uninjured, CFA-inflamed, and o...
